Description

[Technical field]

[0001] The present invention relates to gaming machines such as pachinko gaming machines (commonly referred to as "pachinko machines"). [Background technology]

[0002] Gaming machines such as pachinko machines are equipped with a gaming board having a play area where games are played by game balls flowing down, and a certificate showing information about the gaming machine (game board) is attached to the gaming board (for example, Patent Document 1). In this type of gaming machine, in addition to the certificate, a model sticker and a spec sticker showing the model and specifications of the gaming board are also attached to the gaming board.

[0003] However, if the content displayed on a specific sticker such as a stamp or a specification sticker is difficult to see, some players may become disillusioned with the gaming machine and lose interest in the game. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-49227 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned circumstances, an object of the present invention is to provide a gaming machine that can make displays using specific stickers such as certificate stamps easier to see, thereby preventing a decline in the player's interest. [Means for solving the problem]

[0006] Means 1: In the gaming machine, "A gaming machine equipped with a gaming board having a gaming area along which gaming balls flow, A game is played by a player hitting a game ball into the game area through the player's operation, A lottery is held when the gaming ball passes through a predetermined area provided in the gaming area, and a bonus is awarded to the player according to the result of the lottery; The game board is A sticker base is provided on a front component constituting the outer periphery of the play area so as to be detachable from the front, and a specific sticker is attached to the front surface of the sticker base. The seal base is A demolding trace portion is provided on the rear surface, and a protrusion portion is provided that protrudes rearward beyond the demolding trace portion. It is characterized by:

[0007] Here, "front component member" refers to "a member attached to the front of a flat game panel (game board) with a game area provided in front of it", "a member provided with a rail member such as an outer rail that divides the game area", "a member formed integrally with a flat game panel (game board) with a game area provided in front of it", etc.

[0008] Examples of "specific stickers" include "certificate stamps displaying information about the gaming board, such as the manufacturer's name (manufacturer's name) of the gaming machine (game board), the serial number, and the type of gaming board", "spec stickers displaying information about the gaming board's specifications, such as the probability of a jackpot, number of winning balls, number of jackpot rounds, and count number", "copyright stickers displaying information about the copyright of the gaming machine (game board)", and "AM stickers displaying information about the inspection of the gaming machine (game board)".

[0009] Furthermore, examples of a removable "seal base" include "one that is removable by engaging a locking claw" and "one that is removable by using a mounting screw."

[0010] The "demolding traces" are traces left on the seal base by a mechanism (e.g., an ejector pin, a push-up core, a straight-up core, an ejection core, etc.) for removing the seal base from the molding die (metal mold), and are slightly concave, convex, or inclined compared to other parts. Examples of the shapes of these "demolding traces" include "a part of a circle, such as a semicircle," "circle," "triangle," "square," "pentagon," "hexagon," "polygon," "irregular shape," "star shape," "heart shape," etc.

[0011] Furthermore, examples of the "protrusion" of the seal base include "protrusions in a columnar shape," "protrusions in a rib shape," "protrusions in a lattice shape," "protrusions in a wall shape (dam shape)," etc.

[0012] According to the configuration of Means 1, the present invention is a gaming machine equipped with a gaming board having a gaming area in which gaming balls flow down, the gaming board is detachably attached from the front to a front component that forms the outer periphery of the gaming area, and has a sticker base on the front surface to which a specific sticker is affixed, and the sticker base has a demolding trace portion on its rear surface and a protrusion that protrudes rearward beyond the demolding trace portion (see chapter [9-1. Demolding trace portion provided on front component] in [Form for implementing the invention], the descriptions of the front component 1000, the stamp attachment portion 1012, the gaming board first information display portion 1015, the demolding trace portion 2519, Figures 164 and 165, etc.).

[0013] According to this configuration, in a game board having a game area where games are played with game balls, a removal trace portion is provided on the rear surface of the sticker base on which a special sticker such as a certificate stamp is attached, so that the front surface of the sticker base does not have any unevenness due to the removal trace portion. As a result, the special sticker attached to the front surface of the sticker base does not have any unevenness or wrinkles due to the removal trace portion, making it possible to make the display of the special sticker easier to see and suppressing a decrease in the interest of the player.

[0014] In addition, since the rear surface of the seal base is provided with a protrusion that protrudes further rearward than the demolding traces, the demolding traces of the seal base do not come into contact with the rear member, and rattling due to contact with the demolding traces does not occur. Therefore, even if some vibration is transmitted to the seal base, the seal base does not rattle, and the display of the specific seal affixed to the seal base can be clearly seen.

[0015] It is preferable that the protrusions extend along the rear surface of the seal base in the form of ribs, a grid, a wall, etc. This increases the strength and rigidity of the seal base, reducing distortion of the seal base due to environmental changes such as temperature and humidity, and aging, and allowing the display of the specific seal to be maintained in good condition for a long period of time.

[0016] It is also desirable that the special seal affixed to the seal base hinders access to the parts (e.g., locking claws, mounting screws, etc.) that detachably attach the seal base. This makes it necessary to peel off or tear off the special seal affixed to the seal base when removing the seal base from the game board during assembly or recycling, and leaves traces of the removal of the seal base, making it possible to determine whether the product is a defective product or a reused product, and also eliminates concerns about the special seal (certificate stamp) because it is necessary to tear off the special seal to remove the seal base.

[0017] Also, the sticker base may be made of a transparent material, and the removal trace portion may be provided at a portion that overlaps with the specific sticker in the front-to-back direction. In this way, when the specific sticker is attached to the front surface of the sticker base, the removal trace portion of the sticker base is hidden by the specific sticker and cannot be seen from the front, but when the specific sticker is not attached, the removal trace portion is visible, making it possible to realize that the specific sticker has been forgotten to be attached when assembling the game board.

[0018] In addition, the removal trace portion of the sticker base may be provided in a portion that does not overlap with the specific sticker in the front-rear direction, in other words, in a portion that is not hidden by the specific sticker. This makes it possible to suggest the position where the specific sticker is to be affixed by the removal trace portion.

[0019] Furthermore, the protrusion of the seal base may be provided at least along the outer periphery. In other words, the seal base may be provided with a wall-shaped protrusion (dam portion, peripheral wall portion, etc.) that protrudes from the outer periphery rearward beyond the demolding trace portion. This provides the same effects as those described above, and the protrusion can reinforce the outer periphery of the seal base, thereby increasing the strength and rigidity of the seal base. Therefore, it is possible to reduce distortion of the seal base due to environmental changes such as temperature and humidity, and aging, and the display by the specific seal can be maintained in good condition for a long period of time.

[0020] Means 2: In the configuration of Means 1, "The seal base is The protrusions are provided at least along the outer periphery. The present invention is characterized in that

[0021] According to the configuration of Means 2, the seal base has a protrusion provided at least along the outer circumferential edge (see the descriptions of the certificate stamp base 1012b, the first information seal base 1016, Figures 164 and 165, etc. in the [Form for implementing the invention]).

[0022] According to this configuration, the protrusion of the seal base is provided along the outer periphery. In other words, the seal base is provided with a wall-shaped protrusion (dam portion, peripheral wall portion, etc.) that protrudes from the outer periphery rearward beyond the demolding trace portion. This provides the same effect as above, and the protrusion can reinforce the outer periphery of the seal base, thereby increasing the strength and rigidity of the seal base. Therefore, it is possible to reduce distortion of the seal base due to environmental changes such as temperature and humidity, and aging, and the display by the specific seal can be maintained in good condition for a long period of time.

[0023] Means 3: In the configuration of means 1 or means 2, The gaming machine includes: The pachinko machine is characterized in that the game area is provided with a prize opening into which game balls can enter, and a predetermined bonus is awarded when a game ball enters the prize opening.

[0024] Here, the term "winning port" refers to a "general winning port that is always open within the game area", a "start winning port (starting port) that is always open within the game area and through which a lottery is held to determine whether or not a special pattern will be drawn to determine whether or not a favorable game state in which the player is advantageous will be generated as a predetermined special benefit when a game ball enters", a "variable winning port (variable starting port, accessory winning port, etc.) that allows a game ball to enter as a predetermined special benefit within the game area when a game ball enters a specific receiving port (chucker) within the game area", and a "variable winning port (variable starting port, accessory winning port, etc.) that allows a game ball to enter as a predetermined special benefit depending on the result of a lottery held to determine a normal pattern when a game ball passes through a specific area (gate, through chucker, etc.) within the game area. These include "variable start winning ports (variable start winning ports)"; "variable start winning ports (variable start winning ports) in which, depending on the result of a lottery for a normal pattern that is drawn when a gaming ball passes through a specific area (e.g., a gate, a chucker, etc.) within the gaming area, a gaming ball can enter as a specified bonus, and a lottery for a special pattern is held to determine whether or not the entry of the gaming ball will create an advantageous gaming state that gives the player an advantage as a specified bonus; "V winning ports, which, when a gaming ball that enters a bonus winning port is allocated by an allocation means and enters, create an advantageous gaming state that gives the player an advantage as a specified bonus; and "big winning ports and bonus winning ports that open and close in a specified pattern to allow the entry of a gaming ball, creating an advantageous gaming state that gives the player an advantage as a specified bonus."

[0025] In addition, the "pachinko machine" is a machine equipped with "a lottery means for drawing a special symbol for generating a favorable game state in which a player is advantageous as a predetermined privilege by a game ball entering a start port, a special lottery result display means as a display device for variably displaying the special symbols according to the lottery result of the special symbols drawn by the lottery means and then displaying them as stopped special symbols, and displaying the special lottery result drawn from the combination of the stopped special symbols, and a favorable game state generating means for opening and closing a large prize port in a predetermined pattern when the special lottery result display means displays the special lottery result that generates the favorable game state (so-called digital pachinko machine)" and "a distribution means for distributing game balls that have entered a special feature prize port." and advantageous game state generating means for opening and closing the special feature winning port in a predetermined pattern as a predetermined privilege when the game ball allocated by the allocation means enters the V winning port, thereby generating an advantageous game state in which the player is at an advantage (so-called swing-type machine), "having a large prize port and a special feature winning port, and opening and closing the large prize port or the special feature winning port in a predetermined pattern depending on the result of the lottery for a special pattern drawn by the entry of a game ball into the start port (starting ball entry), and when the game ball that entered the special feature winning port is allocated to the V winning port, the special feature winning port or the large prize winning port is opened and closed in a predetermined pattern as a predetermined privilege, thereby generating an advantageous game state in which the player is at an advantage (so-called multi-function machine)," etc.

[0026] According to the configuration of the third means, the gaming machine is a pachinko machine in which a winning hole into which a gaming ball can enter is provided in the gaming area, and a predetermined privilege is awarded when the gaming ball enters the winning hole. This makes it possible to achieve the action and effect of any of the above-mentioned means in the pachinko machine. Effect of the Invention

[0027] Thus, according to the present invention, a gaming machine can be provided that can make displays using specific stickers such as stamps easier to see, thereby preventing a decline in the player's interest. [Brief description of the drawings]

The left lower connecting member 13 is attached to the lower outer frame member 41 by screwing a screw into the lower outer frame member 41 through the horizontal fixing portion 13a and the lower horizontal fixing portion 13c with the horizontal fixing portion 13a abutting against the upper surface of the left end side of the lower outer frame member 41 and the lower horizontal fixing portion 13c inserted into the notch 41a on the left side surface of the lower outer frame member 41.

[0054] Next, the right outer frame assembly 20 comprises a right outer frame member 21 which extends up and down with a constant width (depth) in the front-to-back direction, an upper right connecting member 22 attached to the upper end of the left side of the right outer frame member 21, a lower right connecting member 23 attached to the lower end of the left side of the right outer frame member 21, an upper hook member 24 attached to the upper part of the left side of the right outer frame member 21, and a lower hook member 25 attached to the lower part of the left side of the right outer frame member 21.

[0055] The right outer frame member 21 extends vertically with a constant cross-sectional shape, and is formed from an extruded aluminum alloy material. The right outer frame member 21 has a recess 21a that is recessed flat toward the left in a rear portion of the right side surface of the member when the right side surface is divided into three equal portions in the front-to-rear direction, a bulge 21b that bulges leftward from a portion of the left side surface opposite the recess 21a, and a hollow portion 21c that penetrates the bulge 21b vertically. The strength and rigidity of the right outer frame member 21 are increased by the recess 21a and the bulge 21b, and the weight is reduced by the hollow portion 21c.

[0056] The right outer frame member 21 has a plurality of grooves extending vertically formed on both the left and right side surfaces. The grooves on the right side surface are V-shaped, and the grooves on the left side surface are semicircular. The right outer frame member 21 is formed in a symmetrical shape to the left outer frame member 11 of the left outer frame assembly 10.

[0057] The upper right connecting member 22 is for connecting the upper end of the outer frame right member 21 and the right end of the outer frame upper member 30. The upper right connecting member 22 includes a flat horizontal fixing portion 22a extending horizontally, a flat upper lateral fixing portion 22b extending upward from the middle in the front-to-rear direction on the right side of the horizontal fixing portion 22a, and a pair of flat lower lateral fixing portions 22c extending downward from both the front and rear sides of the upper lateral fixing portion 22b on the right side of the horizontal fixing portion 22a. The upper right connecting member 22 is formed by bending a flat metal plate.

[0058] The upper right connecting member 22 is attached to the right outer frame member 21 by inserting the rear lower horizontal fixing portion 22c into the hollow portion 21c of the right outer frame member 21, abutting the horizontal fixing portion 22a against the upper end of the right outer frame member 21, and further abutting the front and rear lower horizontal fixing portions 22c against the left side surface of the right outer frame member 21, and then screwing a screw into the lower horizontal fixing portion 22c from the outside of the right side surface of the right outer frame member 21. The upper right connecting member 22 is attached to the upper outer frame member 30 by abutting the horizontal fixing portion 22a against the lower surface of the right end side of the upper outer frame member 30, and inserting the upper horizontal fixing portion 22b into the notch portion 30a on the right side surface of the upper outer frame member 30, and then screwing a screw into the upper outer frame member 30 through the horizontal fixing portion 22a and the upper horizontal fixing portion 22b.

[0059] The right lower connecting member 23 is for connecting the lower end of the outer frame right member 21 and the right end of the outer frame lower assembly 40 (outer frame lower member 41). The right lower connecting member 23 includes a flat horizontal fixing portion 23a extending horizontally, a flat upper horizontal fixing portion 23b extending upward from the right side of the horizontal fixing portion 23a and extending rearward from the horizontal fixing portion 23a, a flat lower horizontal fixing portion 23c extending downward from a portion on the lower side of the upper horizontal fixing portion 23b rearward from the horizontal fixing portion 23a, and a flat abutting portion 23d extending short to the left from the rear side of the upper horizontal fixing portion 23b. The right lower connecting member 23 is formed by bending a flat metal plate.

[0060] The right-lower connecting member 23 is attached to the right outer frame member 21 by screwing a screw into the upper horizontal fixing portion 23b from the outside of the right side surface of the outer frame right member 21 with the rear surface of the abutment portion 23d abutting against the front surface of the bulging portion 21b of the right outer frame member 21, the right surface of the upper horizontal fixing portion 23b abutting against the left surface of the right outer frame member 21, and the lower surface of the horizontal fixing portion 23a coinciding with the lower end of the right outer frame member 21.

[0061] An outer frame hook 653 of a locking unit 650 in the main frame 4, which will be described later, is hooked to the upper hook member 24 and the lower hook member 25. The upper hook member 24 includes a flat mounting portion 24a that extends vertically with a constant width in the front-rear direction and is attached to the left side surface of the outer frame right member 21, and a flat hook piece portion 24b that extends leftward from the front edge of the mounting portion 24a and to which the upper outer frame hook 653 is hooked.

[0062] The lower hook member 25 includes a flat mounting portion 25a which extends vertically with a constant width in the front-to-rear direction and is attached to the left side surface of the outer frame right member 21, a flat hanging piece portion 25b which extends leftward from the front edge of the mounting portion 25a and to which the lower outer frame hook 653 is hooked, and an insertion opening 25c which penetrates the hanging piece portion 25b in the front-to-rear direction and through which the lower outer frame hook 653 can be inserted.

[0063] [2-2. Upper outer frame components] The upper outer frame member 30 of the outer frame 2 will be described in detail mainly with reference to Fig. 16. The upper outer frame member 30 is for connecting the upper ends of the left outer frame assembly 10 and the right outer frame assembly 20, which are spaced apart from each other on the left and right sides. The upper outer frame member 30 has a width in the front-to-rear direction substantially the same as that of the left outer frame member 11 and the right outer frame member 21 in the front-to-rear direction, a constant thickness in the up-down direction, extends in the left-to-right direction, and is made of wood. The upper outer frame member 30 is formed so that its length in the left-to-right direction is the same as that of the lower outer frame member 41 of the lower outer frame assembly 40, which will be described later.

[0064] The upper outer frame member 30 has cutouts 30a at the center in the front-rear direction on both the left and right side surfaces, which are recessed toward the center in the left-right direction while penetrating vertically. The upper horizontal fixing part 12b of the upper left connecting member 12 and the upper horizontal fixing part 22b of the upper right connecting member 22 are inserted into the cutouts 30a at both left and right ends.

[0065] The upper frame member 30 also has a mounting step 30b at its left end, the top and front surfaces of which are recessed from the general surface. The upper frame hinge assembly 50, which will be described later, is attached to this mounting step 30b.

[0066] [2-3. Lower outer frame assembly] The lower frame assembly 40 of the outer frame 2 will be described in detail mainly with reference to Fig. 18. Fig. 18 is an exploded perspective view of the lower frame assembly of the outer frame as viewed from the front. The lower frame assembly 40 connects the lower ends of the left and right frame assemblies 10 and 20, which are spaced apart from each other on the left and right, and serves to close off and decorate the area below the door frame 3 in the pachinko machine 1.

[0067] The lower outer frame assembly 40 comprises a lower outer frame member 41 which extends left and right and connects the lower ends of the left and right outer frame assembly 10 and the right outer frame assembly 20 which are spaced apart left and right, a box-shaped front panel member 42 which is arranged in front of the lower outer frame member 41 and extends left and right along the lower outer frame member 41 and is open at the rear, a box-shaped rear panel member 43 which is attached to the rear side of the front panel member 42 and is attached to the upper surface of the lower outer frame member 41, extending left and right and is open at the front, and an anti-ball jamming mechanism 44 formed at the left end of the upper surface of the rear panel member 43.

[0068] The lower outer frame member 41 has a width in the front-to-rear direction substantially the same as that of the left outer frame member 11 and the right outer frame member 21 in the front-to-rear direction, a constant thickness in the up-down direction, extends in the left-to-right direction, and is made of wood. The lower outer frame member 41 is formed to have a length in the left-to-right direction the same as that of the upper outer frame member 30 in the left-to-right direction.

[0069] The outer frame lower member 41 has cutouts 41a at the center in the front-rear direction on both left and right side surfaces, which penetrate vertically and are recessed toward the center in the left-right direction. The lower lateral fixing portion 13c of the lower left connecting member 13 and the lower lateral fixing portion 23c of the lower right connecting member 23 are inserted and attached into the cutouts 41a at both left and right ends. This allows the lower ends of the left outer frame member 11 and the right outer frame member 21 to be connected to each other.

[0070] The outer frame lower member 41 is recessed from the top surface and has a recess 41b into which the lower part of the back panel member 43 is inserted. The recess 41b extends left and right and extends from a rearward position in the center of the front-rear direction to the front end side. This recess 41b makes the volume of the back panel internal space 40a formed by the front panel front member 42 and the back panel rear member 43 as large as possible.

[0071] The front panel front member 42 has the same left-right length as the outer frame lower member 41, is formed in a horizontally long rectangular box shape with a short depth in the front-to-back direction relative to its height, and is open on the entire rear side. The front panel front member 42 closes the open rear side with the rear panel member 43, thereby forming the front panel internal space 40a which becomes part of the enclosure 624 of the main frame speaker 622 in cooperation with the rear panel member 43. The front panel front member 42 has an elongated hole-shaped opening 42a on the front surface near the right end, which penetrates from front to back and extends from left to right.

[0072] The length of the back panel 43 in the left-right direction is slightly shorter than that of the outer frame lower member 41, and the front is formed in a box shape with an open front. The back panel 43 cooperates with the front panel 42 to form the back panel internal space 40a, which is a part of the enclosure 624 of the main frame speaker 622, by attaching the front panel 42 to the front surface. The back panel 43 has a cylindrical connecting tube portion 43a in the left-right center of the upper surface, which extends left and right, protrudes upward, and communicates with the back panel internal space 40a. The connecting tube portion 43a is inclined so that the upper end is located higher from the front end side, which coincides with the general upper surface of the back panel 43, toward the rear. In this embodiment, the upper end of the connecting tube portion 43a is inclined at an angle of 45 degrees.

[0073] The connecting tube portion 43a has a length in the left-right direction that is approximately 1 / 3 of the length of the entire back panel member 43, and a depth in the front-rear direction that is slightly shorter than the depth of the entire back panel member 43. A plurality of ribs 43b that connect the front end side and the rear end side are provided inside the connecting tube portion 43a. When the main body frame 4 is closed to the outer frame 2, the upper end of the connecting tube portion 43a is connected to a connecting portion 621c of a speaker cover 621 of a speaker unit 620a of a board unit 620 in the main body frame 4, and is in communication with the internal space of the speaker unit 620a, forming an enclosure 624.

[0074] The ball jamming prevention mechanism 44 is intended to prevent the game ball B from being pinched between the outer frame 2 and the main frame 4 by causing the game ball B to remain at the left end of the upper surface of the rear panel member 43, at the portion of the outer frame lower hinge member 60.

[0075] The ball jamming prevention mechanism 44 is formed at the left end of the upper surface of the rear panel member 43 and comprises a mounting portion 44a formed flat to accommodate the outer frame lower hinge member 60 described later, a first discharge outlet 44b opening upward at the left end of the mounting portion 44a, a second discharge outlet 44c opening upward to the right of the first discharge outlet 44b in the mounting portion 44a, a vertical wall portion 44d extending upward from the rear and right sides of the mounting portion 44a, and an upper end protrusion 44e protruding forward from the upper end of the vertical wall portion 44d and inclined so that the upper surface is positioned upward as it extends toward the rear.

[0076] The first discharge opening 44b is formed at a position that coincides with a discharge hole 60d of the outer frame lower hinge member 60 described later. The first discharge opening 44b and the second discharge opening 44c are formed to a size that allows the game ball B to pass through. The first discharge opening 44b and the second discharge opening 44c do not communicate with the front panel internal space 40a, and open to the rear surface of the front panel rear member 43. Therefore, the game ball B that enters the first discharge opening 44b and the second discharge opening 44c can be discharged to the rear of the front panel rear member 43.

[0077] When an illegal tool such as a piano wire is inserted through the gap between the outer frame lower hinge member 60 and the main frame lower hinge assembly 520 described later, the ball-biting prevention mechanism 44 can prevent the illegal tool from entering by the standing wall portion 44d rising from the rear end of the mounting portion 44a. Even if the tip of the illegal tool abuts against the standing wall portion 44d and bends upward, it abuts against the upper end protrusion portion 44e that protrudes forward and is provided at the upper end of the standing wall portion 44d, and further intrusion can be prevented. Therefore, it is possible to prevent illegal acts from being performed through the outer frame lower hinge member 60.

[0078] Incidentally, when the rear end of the placement portion 44a is provided with the standing wall portion 44d, if a game ball B falls onto the placement portion 44a for some reason when the main frame 4 is opened relative to the outer frame 2, the game ball B is likely to remain on the placement portion 44a because the standing wall portion 44d prevents the game ball B from moving rearward from the outer frame 2. If the game ball B remains on the placement portion 44a, the game ball B will be caught between the outer frame 2 and the main frame 4 when the main frame 4 is closed relative to the outer frame 2, causing a problem that the main frame 4 cannot be closed.

[0079] In contrast, in the ball jamming prevention mechanism 44 of this embodiment, the game ball B that has fallen onto the outer frame lower hinge member 60 or onto the mounting portion 44a can be discharged to the rear of the curtain board rear member 43 (rear of the outer frame 2) through the discharge hole 60d of the outer frame lower hinge member 60 and the first discharge outlet 44b, or through the second discharge outlet 44c, thereby preventing the game ball B from getting caught between the outer frame 2 and the main body frame 4.

[0080] The lower outer frame assembly 40 comprises a pair of guide members 45 arranged at a distance from each other on the upper surfaces of the front panel member 42 and the rear panel member 43, a flat grill member 46 which closes the opening 42a of the front panel member 42 from the rear, a port member 47 having two cylinders extending forward and backward and which is attached inside the front panel member 42 so as to close the opening 42a by sandwiching the grill member 46, and a frame-shaped sealing member 48 which is arranged at the upper end of the connecting tube portion 43a of the rear panel member 43.

[0081] The pair of guide members 45 are contacted by the lower end of the door frame 3 when the main body frame 4 is closed against the outer frame 2. The guide members 45 are made of a low-friction material with low friction resistance, making the lower end of the main body frame 4 easier to slide, facilitating opening and closing.

[0082] The grill member 46 is a strip-like plate extending in the left-right direction and has a plurality of blades 46b spaced apart in the up-down direction. The blades 46b are inclined so that the front end is higher than the rear end. The grill member 46 allows ventilation between the inside of the front panel member 42 (front panel internal space 40a) and the outside through the gaps between the blades 46b.

[0083] The port member 47, by means of two cylinders, communicates between the panel internal space 40a (enclosure 624) and the front of the outer frame 2 through the gap between the blade portions 46b of the grill member 46. The port member 47 is formed of two cylinders with a specified inner diameter and a specified length, and can resonate and amplify the low-pitched sounds emitted backward (inside the enclosure 624) from the main frame speaker 622 by the principle of Helmholtz resonance, radiating rich low-pitched sounds to the front (player side) of the outer frame 2. In other words, in this embodiment, the enclosure 624 of the main frame speaker 622 is of a bass reflex type, and can make the player hear deep low-pitched sounds.

[0084] When the main frame 4 is closed against the outer frame 2, the sealing member 48 is sandwiched and compressed between the upper end of the connecting tube portion 43a and the lower end of the connecting portion 621c of the speaker cover 621 on the main frame 4, and prevents sound from within the enclosure 624 of the main frame speaker 622 from leaking between the connecting tube portion 43a and the connecting portion 621c.

[0085] According to the grill member 46 of this embodiment, the air vibrations emitted from the main frame speaker 622 to the outside from the front panel internal space 40a can be directed by the inclined blades 46b through the lower cutout opening 295b of the handle cover 295 in the handle cover unit 290 at the diagonally upper front side toward the front cylinder 291a of the handle cover base 291 in which the handle unit 180 is housed. As a result, when a player inserts his / her fingers inside the handle cover 295 (the front cylinder 291a of the handle cover base 291) and rotates the handle 197 (the device for striking the game ball B), the main frame speaker 622 is vibrated to send air into the front cylinder 291a, surprising the player and providing an unprecedented performance.

[0086] In addition, since the port member 47 is open toward the front, a portion of the sound pressure emitted from the port member 47 through the multiple blade portions 46b of the grill member 46 is emitted forward, so that the sound effects emitted from the port member 47 can be heard by players seated in front of the pachinko machine 1 and other players wandering around the gaming hall in which the pachinko machine 1 is installed. The sound effects can also attract the attention of players, making it possible to provide a pachinko machine 1 that is highly appealing to players.

[0087] Furthermore, since the port member 47 is provided in the lower outer frame assembly 40 of the outer frame 2, the volume of the enclosure 624 of the main frame speaker 622 provided in the main frame 4 can be increased, making it possible to output a deeper bass sound, which entertains the player and prevents a decline in interest.

[0088] [2-4. Outer frame upper hinge assembly] The outer frame upper hinge assembly 50 of the outer frame 2 will be described in detail mainly with reference to Fig. 19. Fig. 19(a) is an exploded perspective view of the outer frame upper hinge assembly of the outer frame when disassembled and viewed from above the front, and Fig. 19(b) is an exploded perspective view of (a) when viewed from below the front. The outer frame upper hinge assembly 50 is attached to the upper end of the outer frame left assembly 10 and the left end of the outer frame upper member 30, and is used to attach the main body frame 4 to the outer frame 2 so as to be hinged and rotatable. The outer frame upper hinge assembly 50 includes an outer frame upper hinge member 51 attached to the upper end of the recess 11a of the outer frame left member 11 and the mounting step portion 30b of the outer frame upper member 30, a locking member 52 attached to the outer frame upper hinge member 51, and a mounting screw 53 that attaches the locking member 52 to the outer frame upper hinge member 51.

[0089] The outer frame upper hinge member 51 includes an upper fixing portion 51a in the form of a horizontally extending flat plate attached to the upper surface of the mounting step portion 30b of the outer frame upper member 30, a flat forward extending portion 51b extending forward from the front edge of the upper fixing portion 51a, a bearing groove 51c extending forward from the middle of the right edge of the forward extending portion 51b to the left-right center of the forward extending portion 51b and penetrating vertically, a flat horizontal fixing portion 51d extending downward from the left edge of the upper fixing portion 51a, and a flat edge wall portion 51e extending downward from the edge from the left edge of the forward extending portion 51b around the front edge to the portion where the bearing groove 51c opens and continuing to the horizontal fixing portion 51d. The outer frame upper hinge member 51 is formed by punching and bending a metal plate by press molding. The outer frame upper hinge member 51 can rotatably support a main body frame upper hinge pin 512 (described later) of the main body frame upper hinge member 510 within the bearing groove 51c.

[0090] The locking member 52 includes a band-shaped locking body 52a extending forward and backward, an operating piece 52b protruding rightward from the rear end of the locking body 52a, an elastically deformable rod-shaped elastic portion 52c extending leftward from the rear end of the locking body 52a and then extending diagonally left forward, and a mounting hole 52d penetrating vertically near the rear end of the locking body 52a. The locking member 52 is made of synthetic resin. The locking member 52 is rotatably attached to the lower surface of the forward extending portion 51b of the outer frame upper hinge member 51 at a position rearward of the bearing groove 51c by a mounting screw 53.

[0091] When the locking member 52 is attached to the outer frame upper hinge member 51, the locking body 52a can block the bearing groove 51c in a plan view, and the right side surface near the front end extends forward so that it can abut against a portion of the edge wall portion 51e of the outer frame upper hinge member 51 that extends to the opening of the bearing groove 51c. In addition, the tip of the elastic portion 52c extending leftward from the rear end of the locking body 52a abuts against the inner circumferential surface of the edge wall portion 51e of the outer frame upper hinge member 51. The locking member 52 is biased in a direction in which the front end rotates leftward around the mounting hole 52d by the biasing force of the elastic portion 52c. Therefore, in a normal state, the right side surface near the front end of the locking body 52a of the locking member 52 abuts against the edge wall portion 51e. In this state, a space capable of accommodating main body frame upper hinge pin 512 of main body frame upper hinge member 510 is formed in a portion of bearing groove 51c forward of lock body 52a.

[0092] By operating the operation piece 52b, the lock member 52 can rotate the lock body 52a against the biasing force of the elastic portion 52c. By operating the operation piece 52b, the lock body 52a can be rotated in a direction in which its front end moves leftward, so that the lock body 52a can be retracted from the bearing groove 51c in a plan view, and the bearing groove 51c can be fully opened. This allows the main body frame upper hinge pin 512 to be inserted into the bearing groove 51c or removed from the bearing groove 51c.

[0093] [2-5. Hinge parts under outer frame] The lower outer frame hinge member 60 of the outer frame 2 will be described in detail mainly with reference to Fig. 16. The lower outer frame hinge member 60 comprises a flat horizontal portion 60a extending horizontally, a flat rising portion 60b rising upward from a portion on the left side of the horizontal portion 60a rearward of the center in the front-rear direction, a lower outer frame hinge pin 60c protruding upward from near the front end of the horizontal portion 60a, and a discharge hole 60d penetrating the horizontal portion 60a from top to bottom and large enough to allow only one game ball B to pass through. The lower outer frame hinge member 60 is formed by punching and bending a metal plate by press molding.

[0094] The horizontal portion 60a of the outer frame lower hinge member 60 is formed in a trapezoidal shape with the left side as the base in a plan view. The outer frame lower hinge pin 60c is cylindrical, and is formed in a truncated cone shape with a narrowed upper end above the vertical center. This outer frame lower hinge pin 60c is attached to a position near the front end of the horizontal portion 60a, which is leftward. The discharge hole 60d is formed in the horizontal portion 60a so as to contact the central portion of the rising portion 60b in the front-rear direction and extend rightward from the left side of the horizontal portion 60a in an inverted U-shape. This discharge hole 60d is formed to be approximately the same size as the first discharge port 44b of the ball jamming prevention mechanism 44 in the outer frame lower assembly 40.

[0095] When assembled to the outer frame 2, the rear of the horizontal portion 60a of the outer frame lower hinge member 60 is placed on the placement portion 44a of the rear panel member 43 of the outer frame lower assembly 40, and is fixed to the rear panel member 43 with screws (not shown). The rising portion 60b is attached with screws (not shown) to a portion forward of the bulging portion 11b on the right side surface of the outer frame left member 11. The outer frame lower hinge member 60 cooperates with the outer frame upper hinge member 51 to attach the main frame 4 so as to be able to open and close by inserting the outer frame lower hinge pin 60c into the outer frame lower hinge hole 521a in the main frame lower hinge assembly 520 of the main frame 4.

[0096] Moreover, in the assembled state of the outer frame 2, the discharge hole 60d coincides with the first discharge opening 44b of the ball jamming prevention mechanism 44 in the outer frame lower assembly 40. This allows the game ball B on the horizontal portion 60a to drop (discharge) to the rear of the outer frame 2 through the discharge hole 60d and the first discharge opening 44b. In more detail, when the main frame 4 is closed to the outer frame 2, the game ball B that has fallen between the outer frame 2 and the main frame 4 rolls to the rear side where the gap is wider, and can be discharged from the discharge hole 60d, since the gap between the outer frame 2 and the main frame 4 gradually narrows as the main frame 4 is closed. In this case, the discharge hole 60d is formed at a position that is approximately the same as the rear end of the main body frame 4 when the main body frame 4 is closed against the outer frame 2 when assembled to the pachinko machine 1. Therefore, by discharging the game ball B that falls between the outer frame 2 and the main body frame 4 through the discharge hole 60d, it is possible to easily prevent the game ball B from rolling rearward beyond the main body frame 4, and it is possible to make it difficult for the game ball B to become trapped in the area of ​​the outer frame lower hinge member 60.

[0137] The left-right length of the first sheet metal part 118a is the same as the left-right length of the intermediate reinforcing frame 117. The left-right length of the second sheet metal part 118b is shorter than that of the first sheet metal part 118a. The second sheet metal part 118b is attached so as to span the left-right central part of the first sheet metal part 118a. The thickness tc of the second sheet metal part 118b is about 1.7 times the thickness of the first sheet metal part 118a.

[0138] When assembled to the door frame 3, the intermediate reinforcing frame 117 is located below the door window 101a and behind the dish unit 200 (the performance operation unit 300 described later) (see Figures 33 and 37). As shown in the figure, the lower end of the glass frame 161 (locking piece 161b) in 160 abuts against the upper surface of the upper flange portion 117b in the intermediate reinforcing frame 117. In other words, the glass unit 160 is placed on the upper flange portion 117b. Furthermore, the lower rear surface (rear surface of the locking piece 161b) of the glass frame 161 in the glass unit 160 abuts against the front surface of the rear flange portion 117c in the intermediate reinforcing frame 117. This allows the intermediate reinforcing frame 117 to restrict the downward movement of the glass unit 160 and the rearward movement of the lower part of the glass unit 160. In this embodiment, the rear surface of the rear flange portion 117c is located forward of the rear surface of the glass unit 160 and does not protrude rearward.

[0139] In this embodiment, the intermediate reinforcement frame 117 has a larger vertical width at both left and right ends than the vertical width at the center in the left and right direction, and is attached to the left reinforcement frame 111 and the right reinforcement frame 112 at the parts where the vertical width is larger, so that it is attached more firmly than the intermediate reinforcement frames in conventional door frames.

[0140] The intermediate reinforcing frame 117 has an upper flange portion 117b, a rear flange portion 117c, and a lower flange portion 117d, and is formed into a cross-sectional shape that combines two crank shapes. The intermediate reinforcing frame 117 is also composed of two metal sheets, a first metal sheet portion 118a and a second metal sheet portion 118b. For this reason, the intermediate reinforcing frame 117 has higher strength and rigidity than the intermediate reinforcing frame 114 of the door frame 3 of the first embodiment. Therefore, the door frame reinforcing unit 110 itself has higher strength and rigidity than the door frame reinforcing unit of a conventional door frame.

[0141] In this way, since the strength and rigidity of the intermediate reinforcement frame 117 (door frame reinforcement unit 110) is increased, the intermediate reinforcement frame 117 (door frame reinforcement unit 110) will not warp (plastically deform) even if a player grabs the upper tray 201 or the lower tray 202 and pulls hard, or pulls hard on the lever operation part 304 of the performance operation unit 300 described later. Therefore, it is possible to prevent a gap from being formed between the door frame 3 and the main body frame 4 due to the intermediate reinforcement frame 117 warping.

[0142] Furthermore, even if an attempt is made to commit fraud by strongly pulling the upper tray 201 or the lever operating portion 304 forward to form a gap between the door frame 3 and the main frame 4, as described above, the intermediate reinforcement frame 117 (door frame reinforcement unit 110), which has increased strength and rigidity, will cause the door frame 3 to plastically deform and no gap will be formed between it and the main frame 4, thereby providing a pachinko machine 1 that has a high deterrent effect against fraudulent activities.

[0143] In addition, the intermediate reinforcement frame 117 has an upper flange portion 117b on which the glass unit 160 is placed, and a rear flange portion 117c extending upward from the upper flange portion 117b, so that it can support the weight of the glass unit 160, and even if an attempt is made to insert an illegal tool between the upper flange portion 117b and the lower end of the glass unit 160, the insertion of the illegal tool can be prevented by the rear flange portion 117c extending upward, thereby providing a pachinko machine 1 that has a high deterrent effect against illegal activity.

[0144] As shown in FIG. 38, the intermediate reinforcing frame 117 is configured such that the distance L1 from the rear surface of the base plate portion 117a to the rear end of the upper flange portion 117b is slightly shorter than the distance L2 from the upper surface of the upper flange portion 117b to the upper end of the rear flange portion 117c. The distance L0 obtained by adding the distance L1 and the distance L2 is longer than the distance (not shown) from the rear surface of the base plate portion 117a to the rear end of the door frame 3. Therefore, if the rear flange portion 117c is not bent upward and is extended backward in the same manner as the upper flange portion 117b, the rear end of the rear flange portion 117c is configured to protrude rearward beyond the rear end of the door frame 3. In other words, the angle at which the rear flange portion 117c is extended (bent) relative to the upper flange portion 117b is set to a length that allows the rear end of the rear flange portion 117c to enter the game board 5 at the rear.

[0145] [3-1e-2. Modified intermediate reinforcement frame] Next, modified examples (modifications 1 to 5) of the intermediate reinforcing frame 117 will be described in detail with reference to Fig. 39 and Fig. 40. Fig. 39(a) is an explanatory diagram showing modified example 1 of the intermediate reinforcing frame in a door frame, (b) is an explanatory diagram showing modified example 2 of the intermediate reinforcing frame, and (c) is an explanatory diagram showing modified example 3 of the intermediate reinforcing frame. Fig. 40(a) is an explanatory diagram showing modified example 4 of the intermediate reinforcing frame in a door frame, and (b) is an explanatory diagram showing modified example 5 of the intermediate reinforcing frame. Note that here, parts having the same configuration as the intermediate reinforcing frame 117 will be described with the same reference numerals.

[0146] (Modification 1 of intermediate reinforcing frame) The intermediate reinforcing frame 117A shown in Fig. 39(a) is made of a single thick metal plate (sheet metal). This intermediate reinforcing frame 117A also provides the same effects as those described above. In addition, since this intermediate reinforcing frame 117A is made of a single sheet metal, there is no need to assemble it with rivets or the like, as compared to when it is made of multiple sheets of metal, and it is possible to reduce costs. Note that this intermediate reinforcing frame 117A may also be provided with a bead portion 117e.

[0147] (Modification 2 of intermediate reinforcing frame) The intermediate reinforcing frame 117B shown in Fig. 39(b) has a lower flange portion 117d extending rearward from the lower end of the base portion 117a. The lower flange portion 117d extending rearward can also increase the strength and rigidity of the intermediate reinforcing frame 117B, achieving the same effects as those described above. The intermediate reinforcing frame 117B may be made of a single metal plate as shown in the figure, or may be made of multiple metal plates like the intermediate reinforcing frame 117 described above. The intermediate reinforcing frame 117B may also be provided with a bead portion 117e.

[0148] (Modification 3 of intermediate reinforcement frame) In the intermediate reinforcing frame 117C shown in FIG. 39(c), the rear end of the upper flange portion 117b extends to the rear surface of the glass unit 160, and the rear flange portion 117c extending upward from the rear end of the upper flange portion 117b is located rearward of the glass unit 160. This intermediate reinforcing frame 117C also provides the same effects as above. In addition, in this intermediate reinforcing frame 117C, the width (depth) in the front-rear direction of the upper flange portion 117b is wider than the upper flange portion 117b of the above intermediate reinforcing frame 117, so that the glass unit 160 can be received over a wide range. The intermediate reinforcing frame 117C may be made of one sheet metal as shown in the figure, or may be made of multiple sheets of metal like the above intermediate reinforcing frame 117. The intermediate reinforcing frame 117C may also be provided with a bead portion 117e. The glass frame 161 of the glass unit 160 may also be provided with a locking piece 161b similar to the above.

[0149] (Modification 4 of intermediate reinforcement frame) In the intermediate reinforcing frame 117D shown in FIG. 40(a), the rear flange portion 117c extends downward from the rear end of the upper flange portion 117b. More specifically, the rear flange portion 117c hangs down from the rear end of the upper flange portion 117b. This configuration also increases the strength and rigidity of the intermediate reinforcing frame 117D, and the upper plate 201 and the lever operation portion 304 of the door frame 3 are not distorted (plastically deformed) even if they are strongly pulled forward. In addition, the glass unit 160 can be placed on the upper flange portion 117b of the intermediate reinforcing frame 117D. Note that, in FIG. 40(a), the rear surface of the rear flange portion 117c does not protrude rearward from the rear surface of the glass unit 160, but the rear flange portion 117c may protrude rearward from the glass unit 160. In addition, the intermediate reinforcing frame 117D may be made of one sheet metal as shown in the figure, or may be made of multiple sheets metal like the intermediate reinforcing frame 117 described above. Moreover, the intermediate reinforcing frame 117D may also be provided with a bead portion 117e. Moreover, the glass frame 161 of the glass unit 160 may be provided with a locking piece 161b similar to that described above.

[0150] (Modification 5 of intermediate reinforcement frame) In the intermediate reinforcement frame 117E shown in FIG. 40(b), the rear flange portion 117c extends downward from the rear end of the upper flange portion 117b. More specifically, the rear flange portion 117c extends obliquely downward from the rear end of the upper flange portion 117b. This configuration also increases the strength and rigidity of the intermediate reinforcement frame 117E, and the intermediate reinforcement frame 117E will not be distorted (plastically deformed) even if the upper tray 201 or the lever operation portion 304 of the door frame 3 is pulled strongly forward. When the door frame 3 is closed, the rear end side of the rear flange portion 117c of the intermediate reinforcement frame 117E is inserted into the game board 5 (here, into the front component 1000). The insertion of the rear flange portion 117c forms a meandering gap, so that even if an illegal tool is inserted along the front surface of the game board 5, it can be blocked by the rear flange portion 117c, and the deterrent effect against illegal acts can be increased.

[0151] The rear flange portion 117c of the intermediate reinforcing frame 117E may be in contact with the game board 5. This allows the door frame 3 and the game board 5 to be positioned via the rear flange portion 117c, and the game board 5 to be supported by the rear flange portion 117c. When the rear flange portion 117c is in contact with the game board 5, the game board 5 may be grounded. Furthermore, the intermediate reinforcing frame 117E may be made of one sheet metal as shown in the figure, or may be made of multiple sheets of metal like the intermediate reinforcing frame 117. The intermediate reinforcing frame 117E may also be provided with a bead portion 117e. The glass frame 161 of the glass unit 160 may also be provided with a locking piece 161b similar to the above.

[0152] [3-1e-3. Other countermeasures examples] Next, a countermeasure against the formation of a gap between the door frame 3 and the main frame 4 by pulling the upper tray 201 etc. forward will be described. As a specific example 1, for example, a distance sensor (e.g., a simple switch, optical sensor, magnetic sensor, proximity sensor, displacement sensor, etc.) that detects the distance (change in distance) between the vicinity of the center in the left-right direction of the intermediate reinforcing frame 117 and the game board 5 may be provided, and when the signal from the distance sensor exceeds a predetermined threshold, an alarm may be issued to that effect. In this case, the distance sensor may be provided in the main frame 4, in the game board 5, or in the door frame 3.

[0153] In the specific example 1, as described above, since the strength and rigidity of the intermediate reinforcing frame 117 (door frame reinforcing unit 110) is increased, the door frame 3 will not be plastically deformed even if it is pulled forward with a strong force. However, if it is pulled strongly, it may be elastically deformed, causing a change in the distance between the door frame 3 and the game board 5, resulting in a gap, so a gap sensor is provided to detect the distance. This makes it possible to detect the change in distance due to elastic deformation by the distance sensor, and to notify the player that the door frame 3 has been pulled forcibly in response to a detection signal from the distance sensor, thereby preventing the player from pulling the door frame 3 unnecessarily hard or from pulling the door frame 3 hard to commit a fraudulent act, thereby providing a pachinko machine 1 with high crime prevention effects.

[0154] As a second specific example, for example, the door frame opening switch (not shown) provided near the right end on the front side of the main frame 4 may be provided at the rear near the center in the left-right direction of the intermediate reinforcing frame 117. As a result, when the upper tray 201 of the door frame 3 is pulled strongly and the center in the left-right direction of the intermediate reinforcing frame 117 is elastically deformed so as to move forward, the door frame opening switch detects the opening of the door frame 3 and issues a warning to that effect. In this case, the door frame opening switch may be provided both near the right end of the main frame 4 and near the center in the left-right direction. Also, the door opening switch near the center in the left-right direction may be provided on the game board 5.

[0155] Furthermore, as a third specific example, for example, a strain sensor may be provided on the intermediate reinforcing frame 117, and when a signal from the strain sensor exceeds a predetermined threshold value, a warning to that effect may be issued.

[0156] As a fourth specific example, for example, a hook-shaped intermediate hook (not shown) that moves in conjunction with the door frame hook 652 of the locking unit 650 may be provided at a rear portion near the center in the left-right direction of the intermediate reinforcing frame 117 in the main frame 4, so that when the door frame 3 is closed relative to the main frame 4, the intermediate hook engages with the intermediate reinforcing frame 117. This makes it possible to prevent the intermediate reinforcing frame 117 near the center in the left-right direction from distorting (plastically or elastically deforming) so as to bulge forward, even if the upper tray 201, etc., is pulled forward, due to the engagement of the intermediate hook.

[0157] [3-1e-4.Summary] The above door frame reinforcement unit 110 has the following technical features.

[0158] (Technical feature background) A pachinko machine as a gaming machine is equipped with a main frame that supports a game board so that it can be attached and detached from the front, and a door frame that is attached to the main frame so that it can be opened and closed from the front. The door frame is hinged at one of the left and right front edges of the main frame and has a window section closed by a glass plate through which the playing area of ​​the game board can be seen from the front.

[0159] In this type of gaming machine, a frame-shaped reinforcing metal sheet made up of multiple metal plates is attached to the door frame, and multiple hooks are engaged from the main frame to the edge of the reinforcing metal sheet on the open side opposite the hinge side, preventing the door frame from opening even if it is pulled forward (for example, patent document: JP 2008-110159 A).

[0160] However, in the technology of the above patent document, for example, when a ball plate (e.g., upper plate, lower plate, etc.) provided on the front surface of the door frame is put with a hand and pulled forward, the door frame (reinforced metal plate) may be distorted so that the center of the door frame in the left-right direction bulges forward. When the door frame is distorted, a gap is formed between the door frame and the main frame, and there is a risk that an illegal tool may be inserted into the gaming machine through the gap.

[0161] Therefore, in consideration of the above-mentioned situation, the following means aims to provide an amusement machine that makes it difficult for a gap to form between the door frame and the main body frame even when the door frame is pulled, thereby preventing fraudulent activities using such gaps.

[0162] (Technical solution) Means 1: In the gaming machine, "A main frame that detachably supports a game board having a game area where a game is played with a game ball from the front, A door frame having a window portion that allows the play area to be viewed from the front and that is provided on the main body frame so as to be openable and closable from the front; A gaming machine comprising: The door frame is a reinforcing sheet metal unit having a first reinforcing portion extending laterally along a lower side of the window portion, The first reinforcing portion is a substrate portion parallel to an opening surface of the window portion; an upper flange portion extending rearward from an upper end edge of the base plate portion; a rear flange portion extending upward or downward from a rear end edge of the upper flange portion; The device is characterized by being equipped with the following features.

[0163] Here, examples of the "first reinforcing portion" include "one made of one metal plate (sheet metal)" and "one made of multiple metal plates (sheet metal)".

[0164] According to the configuration of the first means, the gaming machine includes a main frame supporting a gaming board having a gaming area where a game is played with gaming balls so as to be detachable from the front, and a door frame having a window part that allows the gaming area to be viewed from the front and that is provided on the main frame so as to be openable and closable from the front, the door frame includes a reinforcing sheet metal unit having a first reinforcing part extending left and right along the lower side of the window part, the first reinforcing part including a base part parallel to the opening surface of the window part, an upper flange part extending rearward from the upper end edge of the base part, and a rear flange part extending upward or downward from the rear end edge of the upper flange part (see the description of the door frame reinforcing unit 110, Figs. 35 to 40, etc. in the chapter [3-1. Overall configuration of the door frame base unit] in [Mode for carrying out the invention]).

[0165] As a result, a reinforcing sheet metal unit is provided in the door frame that is provided so as to be able to open and close from the front relative to the main frame, and the strength and rigidity of the door frame are increased by the reinforcing sheet metal unit. This reinforcing sheet metal unit has a first reinforcing part that extends in the left-right direction along the lower side of the window part of the door frame, and the first reinforcing part is provided with a flat base plate part, an upper flange part that extends rearward from the upper end edge of the base plate part, and a rear flange part that extends upward or downward from the upper flange part. When the rear flange part extends upward from the rear end edge of the upper flange part, the cross-sectional shape of the first reinforcing part is crank-shaped, and when the rear flange part extends downward from the rear end edge of the upper flange part, the cross-sectional shape of the first reinforcing part is U-shaped, so that the strength and rigidity can be increased compared to conventional reinforcing parts (reinforcing sheet metal) whose cross-sectional shapes are linear or L-shaped. In other words, because the strength and rigidity of the first reinforcing part of the reinforcing sheet metal unit is higher than before, even if the door frame is pulled strongly forward near the center in the left-right direction, the first reinforcing part will not warp (plastically deform), and no gap will be formed between the door frame and the main body frame. Therefore, even if someone tries to commit fraud by pulling the door frame forward to form a gap between the door frame and the main body frame, the first reinforcing part (reinforcing sheet metal unit) with increased strength and rigidity will not warp the door frame and form a gap between the main body frame, making it possible to provide a gaming machine that is highly deterrent to fraud.

[0166] Furthermore, as mentioned above, the first reinforcement part (reinforcement sheet metal unit) will not distort even if the door frame is pulled strongly forward near the left-right center, so it is possible to provide parts with shapes that are easy for the player to pull forward (for example, upper and lower trays, lever-shaped presentation operation parts, protruding or protruding push button-shaped presentation operation parts, protruding decorative bodies, recessed decorative bodies, etc.), making it possible to provide a gaming machine that can provide even more enjoyment to players.

[0167] A glass unit that closes the window may be placed on the upper flange. This allows the weight of the glass unit to be supported by the upper flange (reinforcement sheet metal unit), so the load on the resin member (e.g., the door frame base) made of synthetic resin that constitutes the door frame can be reduced compared to when the glass unit is supported by the resin member, and early deterioration of the resin member due to excessive load can be suppressed.

[0168] In addition, when the glass unit is placed on the upper flange, if the front surface of the rear flange extending upward from the rear edge of the upper flange is brought into contact with the rear surface of the glass unit, the rear flange can prevent the lower end of the glass unit from moving rearward. This makes it possible to attach the glass unit to the door frame by fixing the upper end of the glass unit, making it easy to attach (remove) the glass unit.

[0169] Furthermore, in the first reinforcing portion, it is desirable to make the sum of the lengths of the upper flange portion and the rear flange portion in the directions along the respective faces longer than the length from the base portion to the front surface of the game board. This makes the sum of the lengths of the upper flange portion and the rear flange portion in the extending directions longer than the distance (length) from the base portion to the front surface of the game board, so that the strength and rigidity of the first reinforcing portion can be increased compared to when that length is shorter, and it can be made less likely to warp even if the door frame is pulled forward.

[0170] Furthermore, as described above, when the sum of the length of the upper flange portion and the length of the rear flange portion is made longer than the length from the base portion to the front surface of the game board, the tip of the rear flange portion can be positioned behind the front surface of the game board. In other words, the rear flange portion can be inserted into the game board from the front. As a result, even if someone tries to insert an illegal tool along the front surface of the game board, the insertion of the illegal tool can be prevented by the rear flange portion inserted into the game board, and a game machine with high deterrent effect against illegal acts can be provided.

[0171] It is also preferable that the first reinforcing portion is provided with a lower flange portion extending forward or backward from the lower edge of the base plate portion. In this way, the first reinforcing portion has an upper flange portion extending backward from the upper edge of the base plate portion, and also has a lower flange portion extending forward or backward from the lower edge of the base plate portion, so that the strength and rigidity of the first reinforcing portion can be further increased, and a gaming machine capable of reliably achieving the above-mentioned effects can be provided.

[0172] Furthermore, it is preferable that the first reinforcing portion has a thicker sheet metal than the other reinforcing portions in the reinforcing sheet metal unit. This also increases the strength and rigidity of the first reinforcing portion, thereby providing a gaming machine that can achieve the same effects as those described above.

[0173] The gaming machine may further be provided with a gap sensor that detects the gap between the first reinforcing part and the gaming board. That is, as described above, since the strength and rigidity of the first reinforcing part (reinforcing sheet metal unit) are increased, the door frame will not be plastically deformed even if it is pulled forward with a strong force. However, if it is pulled strongly, it may be elastically deformed, changing the gap between the door frame and the gaming board and creating a gap, so a gap sensor that detects the gap may be provided. This allows the gap sensor to detect the change in gap due to elastic deformation, making it possible to notify the player that the door frame has been pulled forcibly in response to a detection signal from the gap sensor, and it is possible to stop the player from pulling the door frame unnecessarily hard or pulling the door frame hard to commit a fraudulent act, thereby providing a gaming machine with high crime prevention effect.

[0174] Means 2: In the configuration of Means 1, "The upper flange portion is A glass unit is placed to close the window. It is characterized by:

[0175] According to the configuration of the second aspect, a glass unit that closes the window is placed on the upper flange. (See the description of upper flange 117b and FIG. 37 in the [Mode for Carrying Out the Invention].)

[0176] This allows the weight of the glass unit to be supported by the upper flange portion (reinforcement sheet metal unit), thereby reducing the load on the resin member (e.g., the door frame base) made of synthetic resin that makes up the door frame, and preventing premature deterioration of the resin member due to excessive load.

[0177] In addition, since the glass unit is placed on the upper flange, when the front surface of the rear flange extending upward from the rear edge of the upper flange comes into contact with the rear surface of the glass unit, the rear flange can prevent the lower end of the glass unit from moving rearward. This makes it possible to attach the glass unit to the door frame by fixing the upper end of the glass unit, making it easy to attach (remove) the glass unit.

[0178] Means 3: In the configuration of means 1 or means 2, "The first reinforcing portion is The sum of the lengths of the upper flange portion and the rear flange portion in the directions along their respective faces is longer than the length from the base portion to the front face of the game board. It is characterized by:

[0179] According to the configuration of the third aspect, the sum of the lengths of the upper flange and the rear flange in the first reinforcing portion is longer than the length from the base portion to the front surface of the game board. (See the description of the intermediate reinforcing frame 117 and FIG. 38 in the [Mode for Carrying Out the Invention].)

[0180] As a result, the sum of the extension lengths of the upper flange portion and the rear flange portion is longer than the distance (length) from the base portion to the front of the game board, thereby making it possible to increase the strength and rigidity of the first reinforcing portion compared to when the length is shorter, and making it less likely to distort even when the door frame is pulled forward.

[0181] In addition, since the sum of the length of the upper flange portion and the length of the rear flange portion is longer than the length from the base portion to the front surface of the game board, it is possible to position the tip of the rear flange portion behind the front surface of the game board. In other words, it is possible to insert the rear flange portion into the game board from the front. As a result, even if someone tries to insert an illegal tool along the front surface of the game board, the insertion of the illegal tool can be prevented by the rear flange portion inserted into the game board, and a game machine with high deterrent effect against illegal acts can be provided.

[0182] Means 4: In any one of the configurations of means 1 to 3, "The first reinforcing portion is and a lower flange portion extending forward or rearward from the lower edge of the base portion. It is characterized by:

[0183] According to the configuration of the fourth aspect, the first reinforcing portion is provided with a lower flange portion extending forward or backward from the lower end edge of the base plate portion. (See the description of lower flange portion 117d and FIG. 36 in the [Mode for Carrying Out the Invention].)

[0184] As a result, the first reinforcing portion has an upper flange portion extending rearward from the upper edge of the base portion, and a lower flange portion extending forward or rearward from the lower edge of the base portion, thereby further increasing the strength and rigidity of the first reinforcing portion and providing a gaming machine that can reliably achieve the above-mentioned effects.

[0185] Means 5: In any one of the configurations of means 1 to 4, "The first reinforcing portion is The thickness of the sheet metal is thicker than that of the other reinforcing parts in the reinforcing sheet metal unit. It is characterized by:

[0186] According to the configuration of the fifth aspect, the first reinforcing portion is made thicker than the metal plates of the other reinforcing portions in the reinforcing sheet metal unit. (See the description of the intermediate reinforcing frame 117 and FIG. 36 in the [Mode for Carrying Out the Invention].)

[0187] As a result, the plate thickness of the first reinforcing part is made thicker than the plate thickness of the other reinforcing parts, which also increases the strength and rigidity of the first reinforcing part, and an amusement machine can be provided that can achieve the same effects as described above.

[0188] The first reinforcing portion may have a thick plate thickness over its entire length in the left-right direction, or may have a thick plate thickness only in a portion of its entire length in the left-right direction (for example, within a predetermined range from the center in the left-right direction).

[0189] Means 6: In any one of the configurations of means 1 to 5, A distance sensor that detects the distance between the first reinforcing portion and the game board, The invention is characterized by the fact that it further comprises:

[0190] Here, examples of the "distance sensor" include a "switch," a "optical sensor," a "magnetic sensor," a "proximity sensor," and a "displacement sensor." The distance sensor may be provided on the first reinforcing portion (door frame), on the game board, or on the main body frame. The switch serving as the distance sensor may be, for example, a switch used in a door opening sensor (door opening switch). By using a switch similar to that of the door opening sensor, the input circuit may be designed in the same way as the input circuit of the door opening sensor, etc. Also, since it is a simple contact, depending on the connection method, it is possible to easily combine multiple inputs by connection such as wired-OR.

[0191] According to the configuration of Means 6, the gaming machine further includes a gap sensor that detects the gap between the first reinforcing portion and the gaming board. (See chapter [3-1e-3. Other Countermeasures] in [Mode for Carrying Out the Invention].)

[0192] In this configuration, as described above, the strength and rigidity of the first reinforcing portion (reinforcing sheet metal unit) is increased, so that the door frame will not be plastically deformed even if it is pulled forward with a strong force. However, pulling it too hard may cause elastic deformation, changing the distance between the door frame and the game board and creating a gap, so a gap sensor is provided to detect the distance. This makes it possible to detect the change in distance due to elastic deformation using the gap sensor, and to report that the door frame has been pulled forcibly in response to the detection signal from the gap sensor. This makes it possible to stop players from pulling the door frame unnecessarily hard or from pulling it hard to commit fraud, and thus makes it possible to provide a gaming machine with high crime prevention effects.

[0193] In this way, according to the above solution, it is possible to provide an amusement machine that makes it difficult for a gap to form between the door frame and the main body frame even when the door frame is pulled, thereby preventing fraudulent activities using such gaps.

[0194] (Relationship between the solution of technical features and embodiments) The door window 101a of the door frame base 101 in the door frame base unit 100 of the door frame 3 in this embodiment corresponds to the window portion of the above-mentioned solution means, the door frame reinforcement unit 110 of the door frame base unit 100 in this embodiment corresponds to the reinforcing sheet metal unit of the above-mentioned solution means, and the intermediate reinforcement frame 117 (intermediate reinforcement frames 117A to 117E) of the door frame reinforcement unit 110 in this embodiment corresponds to the first reinforcement portion of the above-mentioned solution means.

[0195] (Characteristic Effects of the Present Embodiment) According to the pachinko machine 1 of this embodiment, the door frame 3, which is provided on the main body frame 4 so as to be able to be opened and closed from the front, is provided with a door frame reinforcing unit 110 made of a combination of multiple metal plates, and the strength and rigidity of the door frame 3 are increased by the door frame reinforcing unit 110. The door frame reinforcing unit 110 has an intermediate reinforcing frame 117 extending in the left-right direction along the lower side of the door window 101a of the door frame 3, and the intermediate reinforcing frame 117 is provided with a flat board portion 117a, an upper flange portion 117b extending rearward from the upper end edge of the board portion 117a, and a rear flange portion 117c extending upward or downward from the upper flange portion 117b. When the rear flange portion 117c extends upward from the rear end edge of the upper flange portion 117b, the cross-sectional shape of the intermediate reinforcement frame 117 (intermediate reinforcement frame 117A, intermediate reinforcement frame 117B, intermediate reinforcement frame 117C) is crank-shaped, and when the rear flange portion 117c extends downward from the rear end edge of the upper flange portion 117b, the cross-sectional shape of the intermediate reinforcement frame 117D (intermediate reinforcement frame 117E) is U-shaped, so that the strength and rigidity can be increased compared to conventional reinforcement parts (intermediate reinforcement frames) whose cross-sectional shapes are linear or L-shaped. In other words, since the strength and rigidity of the intermediate reinforcement frame 117 of the door frame reinforcement unit 110 is increased compared to conventional ones, the intermediate reinforcement frame 117 does not warp (plastically deform) even if the vicinity of the center in the left-right direction of the door frame 3 is strongly pulled forward, and no gap is formed between the door frame 3 and the main frame 4. Therefore, even if an attempt is made to commit fraud by pulling the door frame 3 forward to form a gap between the door frame 3 and the main frame 4, the intermediate reinforcement frame 117 (door frame reinforcement unit 110), which has increased strength and rigidity, will not cause the door frame 3 to distort and form a gap between it and the main frame 4, thereby providing a pachinko machine 1 that has a high deterrent effect against fraudulent activities.

[0196] Furthermore, as mentioned above, even if the door frame 3 is pulled strongly forward near the center in the left-right direction, the intermediate reinforcement frame 117 (door frame reinforcement unit 110) will not be distorted, so it is possible to provide shapes that are easy for the player to pull forward (for example, an upper tray 201 or lower tray 202, a lever-shaped presentation operation unit (lever operation unit 304), a protruding or protruding push button-shaped presentation operation unit (press operation unit 303), a protruding decorative body, a recessed decorative body, etc.), making it possible to provide a pachinko machine 1 that is more entertaining to players.

[0197] Furthermore, since the glass unit 160 that closes the door window 101a is placed on the upper flange portion 117b, the weight of the glass unit 160 can be supported by the upper flange portion 117b (door frame reinforcement unit 110).This reduces the load on the resin member (e.g., the door frame base 101) made of synthetic resin that constitutes the door frame 3, and suppresses early deterioration of the resin member due to excessive load.

[0198] Furthermore, since glass unit 160 is placed on upper flange portion 117b and the rear surface of glass unit 160 abuts against the front surface of rear flange portion 117c extending upward from the rear end edge of upper flange portion 117b, rear flange portion 117c can prevent rearward movement of the lower end side of glass unit 160. This makes it possible to attach glass unit 160 to door frame 3 by fixing only the upper end side of glass unit 160, making it easy to attach (remove) glass unit 160.

[0199] Furthermore, in the intermediate reinforcement frame 117, the sum (L0) of the lengths (L1 and L2) in the directions along each surface of the upper flange portion 117b and the rear flange portion 117c is longer than the length from the base portion 117a to the front surface of the game board 5. Therefore, the strength and rigidity of the intermediate reinforcement frame 117 can be increased compared to when the length is shorter, and the intermediate reinforcement frame 117 is less likely to distort even when the door frame 3 is pulled forward.

[0200] In addition, since the sum (L0) of the length L1 of the upper flange portion 117b and the length L2 of the rear flange portion 117c is longer than the length from the base portion 117a to the front surface of the game board 5, it is possible to position the tip of the rear flange portion 117c behind the front surface of the game board 5. In other words, it is possible to insert the rear flange portion 117c into the game board 5 from the front, as in the intermediate reinforcing frame 117E. As a result, even if someone tries to insert an illegal tool along the front surface of the game board 5, the intrusion of the illegal tool can be prevented by the rear flange portion 117c inserted into the game board 5, and a pachinko machine 1 with a high deterrent effect against illegal acts can be provided.

[0201] In addition, since the intermediate reinforcement frame 117 is provided with a lower flange portion 117d extending forward or rearward from the lower edge of the base portion 117a in addition to the upper flange portion 117b, the strength and rigidity of the intermediate reinforcement frame 117 can be further increased, and a pachinko machine 1 can be provided that can reliably achieve the above-mentioned effects.

[0202] Furthermore, the intermediate reinforcement frame 117 is made thicker than the sheet metal of the other reinforcing parts in the door frame reinforcement unit 110 (left reinforcement frame 111, right reinforcement frame 112, upper reinforcement frame 113), which also increases the strength and rigidity of the intermediate reinforcement frame 117 (door frame reinforcement unit 110), making it possible to provide a pachinko machine 1 that can achieve the same effects as described above.

[0203] Also, a distance sensor for detecting the distance between the intermediate reinforcing frame 117 and the game board 5 may be further provided. That is, as described above, since the strength and rigidity of the intermediate reinforcing frame 117 (door frame reinforcing unit 110) are increased, the door frame 3 will not be plastically deformed even if it is pulled forward with a strong force. However, if it is pulled strongly, it may be elastically deformed, changing the distance between the door frame 3 and the game board 5 and creating a gap, so a distance sensor for detecting the distance is provided. As a result, since the distance sensor can detect the change in distance due to elastic deformation, it is possible to notify the player that the door frame 3 has been pulled forcibly in response to the detection signal from the distance sensor, and it is possible to stop the player from pulling the door frame 3 unnecessarily hard or from pulling the door frame 3 hard to commit a fraudulent act, and a pachinko machine 1 with high crime prevention effect can be provided.

[0204] [3-1f. Door frame upper hinge assembly] The upper door-frame hinge assembly 120 of the door-frame base unit 100 will be described mainly with reference to Figures 34 and 35. The upper door-frame hinge assembly 120 is attached to the upper left corner of the door-frame reinforcement unit 110 when viewed from the front. The upper door-frame hinge assembly 120 is for attaching the door frame 3 to the main body frame 4 so as to be hinged and rotatable in cooperation with the lower door-frame hinge member 125. The upper door-frame hinge assembly 120 includes a hinge bracket 121 attached to the door-frame reinforcement unit 110, an upper door-frame hinge pin 122 attached to the hinge bracket 121 so as to be movable in the up-down direction, a flange member 123 attached to the upper door-frame hinge pin 122, and a lock spring 124 that biases the upper door-frame hinge pin 122 to move upward.

[0205] The hinge bracket 121 includes a flat mounting piece 121a that is rectangular when viewed from the front, and flat protruding pieces 121b that extend forward from the upper and lower sides of the mounting piece 121a. The mounting piece 121a of the hinge bracket 121 is attached to the door frame reinforcement unit 110. The hinge bracket 121 is formed by bending a metal plate.

[0206] The door-frame upper hinge pin 122 is a cylindrical metal rod bent into an L-shape. When assembled to the door-frame upper hinge assembly 120, the portion of the door-frame upper hinge pin 122 that extends vertically penetrates from below near the front ends of the pair of protruding pieces 121b in the hinge bracket 121, the upper end extends upward beyond the upper protruding piece 121b, and the portion that extends horizontally abuts against the lower surface of the lower protruding piece 121b. The upper end of the door-frame upper hinge pin 122 is rotatably inserted into the door-frame upper hinge hole 511a of the upper hinge main body 511 in the main body frame upper hinge member 510 of the main body frame 4.

[0207] The flange member 123 is an E-ring, and is attached to a portion between the pair of protruding pieces 121b of the door-frame upper hinge pin 122. The lock spring 124 is formed in a coil shape, and is placed around a portion of the door-frame upper hinge pin 122 that extends vertically between the flange member 123 and the lower protruding piece 121b of the hinge bracket 121. The lock spring 124 urges the door-frame upper hinge pin 122 upward via the flange member 123.

[0208] In the upper door-frame hinge assembly 120, the upper door-frame hinge pin 122 is biased upward by the lock spring 124, and the horizontally extending portion of the lower end of the upper door-frame hinge pin 122 abuts against the lower surface of the lower protruding piece 121b, restricting further upward movement. In this state, the upper end of the upper door-frame hinge pin 122 protrudes a predetermined amount above the upper surface of the upper protruding piece 121b.

[0209] When the horizontally extending portion of the lower end of the door-frame upper hinge pin 122 of the door-frame upper hinge assembly 120 is moved downward against the biasing force of the lock spring 124, the door-frame upper hinge pin 122 can be moved downward as a whole, and the upper end of the door-frame upper hinge pin 122 can be retracted below the upper surface of the upper protruding piece 121b. Therefore, the door-frame upper hinge assembly 120 can insert the upper end of the door-frame upper hinge pin 122 into the door-frame upper hinge hole 511a of the main body frame upper hinge member 510 from below, and can pull it out downward. As a result, by inserting the upper end of the door-frame upper hinge pin 122 into the door-frame upper hinge hole 511a of the main body frame upper hinge member 510, the upper left end of the door frame 3 as viewed from the front can be supported so as to be hinge-rotatable relative to the main body frame 4.

[0210] Furthermore, in the upper door-frame hinge assembly 120, the portion of the upper door-frame hinge pin 122 that extends vertically is positioned coaxially with a lower door-frame hinge pin 126 of a lower door-frame hinge member 125 described below. This allows the upper door-frame hinge pin 122 and the lower door-frame hinge pin 126 to hinge rotate the door frame 3 relative to the main body frame 4 in a favorable state.

[0211] [3-1g. Door frame bottom hinge parts] The door-frame bottom hinge member 125 of the door-frame base unit 100 will be described mainly with reference to Figures 34 and 35. The door-frame bottom hinge member 125 is attached to the lower left corner of the door-frame reinforcement unit 110 when viewed from the front. The door-frame bottom hinge member 125 cooperates with the door-frame upper hinge assembly 120 to attach the door frame 3 to the main body frame 4 so that it can rotate about a hinge.

[0212] The lower door frame hinge member 125 comprises a flat mounting piece 125a which is attached to the door frame reinforcement unit 110 and is rectangular when viewed from the front, a flat protruding piece 125b which extends forward from the lower edge of the mounting piece 125a, and a lower door frame hinge pin 126 (see Figure 35, etc.) which protrudes downward from the underside near the front end of the protruding piece 125b.

[0213] The mounting piece 125a and the protruding piece 125b of the lower door-frame hinge member 125 are formed by bending a metal plate. The lower door-frame hinge pin 126 is a cylindrical metal bar with a tapered chamfer on the outer periphery of the lower end. When assembled to the door-frame base unit 100, the lower door-frame hinge pin 126 is attached to a portion of the protruding piece 125b that is coaxial with the portion of the upper door-frame hinge pin 122 of the upper door-frame hinge assembly 120 that extends vertically.

[0214] This door-frame lower hinge member 125 can support the door frame 3 relative to the main body frame 4 so that it can rotate about a hinge by inserting the door-frame lower hinge pin 126 into the door-frame lower hinge hole 522a of the main body frame lower hinge assembly 520.

[0215] [3-1h. Cylinder lock] The cylinder lock 130 in the door frame base unit 100 of the door frame 3 will be described in detail mainly with reference to Figs. 41 to 43. Fig. 41(a) is a perspective view of the cylinder lock of the door frame seen from the front, (b) is a perspective view of the cylinder lock of (a) seen from the rear front, (c) is a perspective view of the cylinder lock in a conventional pachinko machine seen from the front, and (d) is a perspective view of the cylinder lock of (a) seen from the rear. Fig. 42(a) is an exploded perspective view of the cylinder lock of Fig. 41(a) seen from the front, and (b) is an exploded perspective view of the cylinder lock of Fig. 41(a) seen from the rear. Fig. 43(a) is an explanatory view showing the movable mechanism of the cylinder lock of Fig. 41(a) from the front, (b) is an explanatory view of the cylinder lock shown in a state rotated 90 degrees counterclockwise from the state of (a), and (c) is an explanatory view of the cylinder lock shown in a state rotated 90 degrees clockwise from the state of (a).

[0216] The cylinder lock 130 is attached to the cylinder mounting frame 115 of the door frame reinforcement unit 110, and cooperates with the locking unit 650 of the main frame 4 to be used for opening and closing the door frame 3 and the main frame 4, and for opening and closing / locking the outer frame 2 and the main frame 4. The cylinder lock 130 comprises a cylindrical cylinder body 131 extending forward and backward, a keyhole 132 formed in the front end surface of the cylinder body 131, and a rotation transmission member 133 provided at the rear of the cylinder body 131, which rotates together with the rotation of a regular key inserted in the keyhole 132.

[0217] The cylinder body 131 of the cylinder lock 130 penetrates the front piece of the cylinder mounting frame 115 from the rear, and the rear end is attached to the front piece. The rotation transmission member 133 is formed in a cylindrical shape (more specifically, a conical cylinder shape whose diameter increases toward the rear) with an open rear, and has a pair of notches cut from the rear end toward the front at positions opposite each other across the central axis. The rotation transmission member 133 is formed so that the transmission cylinder 654 of the locking unit 650 in the main body frame 4 is inserted from the rear, and the rotation of the rotation transmission member 133 (the key inserted in the keyhole 132) can be transmitted to the transmission cylinder 654 to rotate it by inserting a pair of protrusions of the transmission cylinder 654 into the pair of notches.

[0218] In more detail, the cylinder lock 130 comprises a first cam member 134 provided at the rear end side of the cylinder body 131 and which rotates together with the genuine key inserted into the keyhole 132 when it is rotated; a second cam member 135 which is rotatably attached around an axis in the front-to-rear direction at a position below the cylinder body 131 on the cylinder mounting frame 115; a strip-shaped first arm 136 which has an upper end side rotatably attached at a position to the right of the rotation center of the first cam member 134 and a lower end side rotatably attached at a position to the right of the rotation center of the second cam member 135; and a strip-shaped second arm 137 which has an upper end side rotatably attached at a position below the rotation center of the first cam member 134 and a lower end side rotatably attached at a position below the rotation center of the second cam member 135.

[0219] The cylinder lock 130 also includes a rear cover 138 attached to the cylinder mounting frame 115 so as to cover the cylinder body 131, the first cam member 134, the first arm 136, and the second arm 137 from the rear, except for the second cam member 135 (rotation transmission member 133), and a rivet 139 that attaches both the upper and lower ends of each of the first arm 136 and the second arm 137 to the first cam member 134 and the second cam member 135, respectively, so that they can rotate.

[0220] The first cam member 134 has an upper end side of a first arm 136 attached to the rear side, and an upper end side of a second arm 137 attached to the front side. The second cam member 135 is rotatably attached from the rear side by the cylinder mounting frame 115, and a rotation transmission member 133 is attached to the rear side across the front side of the cylinder mounting frame 115 so as to be rotatable together with the first cam member 134. The second cam member 135 has a lower end side of the first arm 136 attached to the front side, and a lower end side of the second arm 137 attached to the front side forward of the first arm 136.

[0221] In each of the first cam member 134 and the second cam member 135, a portion where the first arm 136 is attached and a portion where the second arm 137 is attached are separated by an angle of 90 degrees around the respective rotation axes. Also, in each of the first cam member 134 and the second cam member 135, the portion where the first arm 136 is attached is provided at a position farther from the rotation center than the portion where the second arm 137 is attached.

[0222] The rear cover 138 is removably attached to the cylinder mounting frame 115 at its upper end by screws (not shown), with the shaft portion 138a, which protrudes cylindrically outward from the lower ends of both the left and right sides, engaged with the L-shaped locking slit 115b of the cylinder mounting frame 115.

[0223] In this cylinder lock 130, the cylinder mounting frame 115, the cylinder body 131, the rotation transmission member 133, the first cam member 134, the second cam member 135, the first arm 136, and the second arm 137 are formed from metal.

[0224] When the cylinder lock 130 is assembled to the door frame 3 , the front end of the cylinder body 131 is substantially aligned with the front end of the cylinder insertion opening 440 b of the door frame right side unit 430 .

[0225] Here, the conventional cylinder lock 130A will be described. As shown in Figures 41(c) and (d), the conventional cylinder lock 130A has a cylinder body 131 that penetrates the front piece of the cylinder mounting frame 115A from the rear and has its rear end attached to the front piece. In this cylinder lock 130A, a rotation transmission member 133 is provided on the axis of the cylinder body 131.

[0226] Next, the operation of the cylinder lock 130 of this embodiment will be described. In the conventional cylinder lock 130, as shown in Figures 41(c) and (d), the rotation transmission member 133 is provided on the axis of the cylinder body 131, whereas in the cylinder lock 130 of this embodiment, as shown in Figures 41(a) and (b), the rotation transmission member 133 is provided at a position spaced downward from the axis of the cylinder body 131.

[0227] 43(a), in the normal state, the upper and lower ends of the first arm 136 are attached to the right of the rotation centers of the first cam member 134 and the second cam member 135, respectively, and the upper and lower ends of the second arm 137 are attached to the lower of the rotation centers of the first cam member 134 and the second cam member 135. The cylinder body 131 can be rotated by an angle of 90 degrees in both the clockwise and counterclockwise directions from the normal state with the use of a regular key.

[0228] In this state, when the first cam member 134 is rotated counterclockwise via the cylinder of the cylinder body 131 with the key inserted in the keyhole 132, the first arm 136 and the second arm 137 move upward. At this time, since the upper end side of the first arm 136 is attached to the right of the rotation center of the first cam member 134, a large force acts on the first arm 136 to rotate the second cam member 135 counterclockwise, whereas since the upper end side of the second arm 137 is attached below the rotation center of the first cam member 134, almost no force acts on the second arm 137 to rotate the second cam member 135 counterclockwise.

[0229] In this way, when the first cam member 134 rotates counterclockwise from the normal state, the force is transmitted mainly via the first arm 136, the second cam member 135 rotates counterclockwise, and the rotation transmission member 133 rotates together with the second cam member 135. The force acting upward due to the counterclockwise rotation of the first cam member 134 is proportional to the left-right distance between the portion where the first arm 136 and the second arm 137 are attached to the first cam member 134 and the rotation center of the first cam member 134. Therefore, as the first cam member 134 rotates counterclockwise from the normal state, the force acting upward in the first arm 136 decreases, whereas the force acting upward in the second arm 137 increases.

[0230] Therefore, when first cam member 134 exceeds 45 degrees in counterclockwise rotation from the normal state, the force acting upward on second arm 137 becomes greater than that on first arm 136, and second cam member 135 rotates counterclockwise mainly via second arm 137. Then, the key inserted in keyhole 132 can be rotated counterclockwise up to an angle of 90 degrees from the normal state (see FIG. 43(b)).

[0231] Furthermore, when using the key to rotate the key 90 degrees counterclockwise from the normal state and then rotate it 90 degrees clockwise to return it to the normal state, the operation is reversed to that described above.

[0232] On the other hand, when the first cam member 134 is rotated clockwise via the cylinder of the cylinder body 131 by a key inserted in the keyhole 132 from the normal state, the first arm 136, the upper end of which is attached to the right of the rotation center of the first cam member 134, moves downward, and the second arm 137, the upper end of which is attached below the rotation center of the first cam member 134, moves upward. At this time, since the upper end of the first arm 136 is attached to the right of the rotation center of the first cam member 134, a large force acts to rotate the second cam member 135 in the clockwise direction by the first arm 136, whereas since the upper end of the second arm 137 is attached below the rotation center of the first cam member 134, almost no force acts from the second arm 137 to rotate the second cam member 135 in the clockwise direction.

[0233] In this way, when the first cam member 134 rotates in the clockwise direction from the normal state, the force is transmitted mainly via the first arm 136, the second cam member 135 rotates in the clockwise direction, and the rotation transmission member 133 rotates together with the second cam member 135. The force that transmits the rotation of the first cam member 134 by the first arm 136 and the second arm 137 to the second cam member 135 is proportional to the left-right distance between the portion where the first arm 136 and the second arm 137 are attached to the first cam member 134 and the rotation center of the first cam member 134. Therefore, as the first cam member 134 rotates in the clockwise direction from the normal state, the force of the first arm 136 that tries to rotate the second cam member 135 decreases, whereas the force of the second arm 137 that tries to rotate the second cam member 135 increases.

[0234] Therefore, when first cam member 134 exceeds 45 degrees in the clockwise rotation angle from the normal state, the force of second arm 137 tending to rotate second cam member 135 becomes greater than that of first arm 136, and second cam member 135 rotates in the clockwise direction mainly via second arm 137. Then, the key inserted in keyhole 132 can be rotated up to an angle of 90 degrees in the clockwise direction from the normal state (see FIG. 43(c)).

[0235] Furthermore, when using the key to rotate the lock 90 degrees clockwise from its normal state to return it to its normal state by rotating it 90 degrees clockwise again, the operation is the reverse of that described above.

[0236] In this way, according to the cylinder lock 130 of the present embodiment, the first cam member 134 and the second cam member 135 are connected by the first arm 136 and the second arm 137 which are attached at a 90 degree angle from each other to transmit rotation, so that no matter what rotation position the first cam member 134 (the key inserted in the keyhole 132) is in, the rotation can be transmitted by at least one of the first arm 136 and the second arm 137 to rotate the second cam member 135 (rotation transmission member 133), thereby enabling the door frame 3 and the main frame 4 to be locked and unlocked smoothly.

[0237] Furthermore, according to the cylinder lock 130 of this embodiment, by transmitting rotation using the first arm 136 and the second arm 137 as a rotation transmission mechanism, the axis of the rotation transmission member 133 (the transmission cylinder 654 of the locking unit 650 in the main body frame 4) can be set at a different position relative to the axis of the cylinder body 131. This makes it possible to change the position of the cylinder body 131 in the door frame 3 to any position without changing the locking unit 650, and allows the cylinder body 131 (keyhole 132) to be provided in a position that does not interfere with the decoration of the door frame 3, thereby making it possible to provide a pachinko machine 1 with a highly decorative door frame 3.

[0238] Furthermore, as described above, even if the position of the cylinder body 131 is changed in the door frame 3, there is no need to change the locking unit 650 in the main body frame 4, so the locking unit 650 can be reused, thereby suppressing any increase in costs associated with the pachinko machine 1.

[0239] Incidentally, in the conventional cylinder lock 130A, the rotation transmission member 133 is provided at the rear of the cylinder body 131, so that a fraudulent person who knows the configuration may insert a tool from the front to the rear of the cylinder body 131 and use the tool to fraudulently rotate the rotation transmission member 133, thereby opening the door frame 3 and committing a fraudulent act. In contrast, in the cylinder lock 130 of this embodiment, the rotation transmission member 133 is provided at a position away from the axis (rear) of the cylinder body 131, so even if a tool is inserted at the rear of the cylinder body 131 to rotate the rotation transmission member 133, the rotation transmission member 133 cannot be rotated because the rotation transmission member 133 is not present at that position, and therefore it is possible to prevent a fraudulent act of opening the door frame 3, the main body frame 4, etc.

[0240] Furthermore, in cylinder lock 130, second arm 137 connects portions of first cam member 134 and second cam member 135 that are spaced apart by a rotation angle of 90 degrees relative to first arm 136. Therefore, even if the portions of either first arm 136 or second arm 137 attached to first cam member 134 and second cam member 135 are positioned on a line connecting the center of first cam member 134 and the center of second cam member 135, the other of first arm 136 or second arm 137 connects the portions that are furthest from the line connecting the center of first cam member 134 and the center of second cam member 135. Therefore, even if one of first arm 136 or second arm 137 is positioned at the dead center of first cam member 134 and second cam member 135 and therefore cannot transmit rotation from first cam member 134 to second cam member 135, the other of first arm 136 or second arm 137 can transmit rotation from first cam member 134 to second cam member 135. As a result, there is no significant resistance to the rotation of first cam member 134 and the key inserted in keyhole 132 can be rotated smoothly, making it easy to lock and unlock the door, and also making it possible to avoid forcing the key inserted in the keyhole to rotate, thereby preventing damage to the key.

[0241] Furthermore, since the rotation of the key inserted into the keyhole 132 is transmitted to the rotation transmission member 133 located in an eccentric position by two arms, the first arm 136 and the second arm 137, even if one of the arms is damaged for some reason, the rotation can be transmitted by the remaining arm, making it possible to provide a pachinko machine 1 having a highly reliable cylinder lock 130.

[0242] In addition, the rotation of the key inserted in the keyhole 132 is transmitted to the rotation transmission member 133 located at an eccentric position by the smooth rod-shaped (strip-shaped) first arm 136 and second arm 137. If the rotation were transmitted by a gear, there is a risk that the gear would rotate and rotate the rotation transmission member 133 by catching the tip of a tool on the teeth of the gear. However, by making the first arm 136 and the second arm 137 into a rod-shaped arm with a smooth surface, it is possible to make it difficult for the tip of a tool to get caught on the first arm 136 or the second arm 137. This makes it possible to prevent the rotation transmission member 133 from being rotated by moving the first arm 136 or the second arm 137. This makes it possible to reliably prevent the locking unit 650 from being operated improperly and the door frame 3 or the main frame 4 from being unlocked.

[0243] In addition, in the cylinder lock 130 of this embodiment, the first arm 136 and the second arm 137 are used as a rotation transmission mechanism for transmitting the rotation of the first cam member 134 to the second cam member 135, but this is not limited to this, and for example, a rotation transmission mechanism using multiple gears, a rotation transmission mechanism using a gear and a rack gear, a rotation transmission mechanism using a sprocket and a chain, a rotation transmission mechanism using a pulley and a belt, etc. may also be used.

[0244] [3-1i. Ball feeding unit] The ball feeding unit 140 of the door frame base unit 100 will be described in detail mainly with reference to Figures 44 and 45. Figure 44(a) is a perspective view of the ball feeding unit of the door frame base unit seen from the front, and (b) is a perspective view of the ball feeding unit seen from the back. Figure 45(a) is an exploded perspective view of the ball feeding unit seen from the front, and (b) is an exploded perspective view of the ball feeding unit seen from the back with the rear case and anti-tampering member removed. The ball feeding unit 140 can supply the game balls B supplied from the upper tray 201 of the tray unit 200 one by one to the ball launching device 540 of the main frame 4, and can extract the game balls B stored in the upper tray 201 to the lower tray 202 by operating the upper tray ball extraction button 222.

[0245] The ball feeding unit 140 includes a box-shaped front cover 141 having an entrance 141a penetrating in the front-rear direction through which the game balls B are supplied from the upper tray 201 of the tray unit 200 and a ball ejection port 141b opening below the entrance 141a, and a rear cover 142 that is box-shaped and has an open front end, a rear cover 142 that closes the rear end of the front cover 141 and has a ball supply port 142a for supplying the game balls B that enter from the entrance 141a of the front cover 141 penetrating in the front-rear direction to the ball launching device 540, and a rear cover 142 and The ball removal member 143 is rotatably supported around an axis extending in the front-to-back direction between the front cover 141 and the front cover 141, and has a partition portion 143a that separates the entrance 141a and the ball removal opening 141b at the rear of the front cover 141, a ball feeding member 144 that is rotatably supported around an axis extending in the up-down direction between the front cover 141 and the rear cover 142 and sends the game balls B on the partition portion 143a of the ball removal member 143 one by one to the ball supply opening 142a of the rear cover 142, and a ball feeding solenoid 145 that rotates the ball feeding member 144.

[0246] As shown in the figure, when viewed from the front, this ball feeding unit 140 has a ball feeding member 144 arranged to the right of the entrance 141a, a ball removal member 143 arranged to the left of the ball feeding member 144, and a ball feeding solenoid 145 arranged to the right of the ball feeding member 144.

[0247] The front cover 141 of the ball feeding unit 140 has an arc-shaped slit 141c formed concentrically with the center of rotation of the ball extracting member 143 to the left of the ball extracting opening 141b when viewed from the front, and the operating rod 143c of the ball extracting member 143 described later extends forward from this slit 141c. In addition, the upper side of the front cover 141 extends upward from the upper edge of the entrance 141a, and is formed so as to close from the rear the portion of the ball feeding guideway and the ball extracting guideway 241c of the rear base 241 in the upper tray ball extracting unit 240 that is open to the rear at the upstream end side when the door frame 3 is assembled.

[0248] The ball removal member 143 comprises a partition portion 143a which acts as a partition between the entrance 141a and the ball removal opening 141b below the entrance 141a and has its upper surface lowering toward the ball feeding member 144, a pivoting rod portion 143b which extends downward from the end of the partition portion 143a opposite the ball feeding member 144 and is bent in an L-shape from near the middle in the vertical direction toward the lower center of the ball removal opening 141b, with its lower end supported for rotation around an axis extending in the front-to-rear direction, a rod-shaped operating rod 143c which protrudes forward from the upper end of the rotating rod portion 143b, and a weight portion 143d which protrudes from the side of the rotating rod portion 143b below the operating rod 143c on the opposite side from the partition portion 143a. The operating rod 143c of the ball removal member 143 is formed so as to protrude forward through an arc-shaped slit 141c formed in the front cover 141 (see FIG. 44(a)). The operating rod 143c abuts against the upper end (upper surface) of the operating transmission part 242b of the upper tray ball removal slider 242, which moves downward by pressing the upper tray ball removal button 222 of the tray unit 200, through the ball feed opening 101e of the door frame base 101.

[0249] The ball feeding member 144 has a cutoff portion 144a that is fan-shaped in plan view and is centered on the rotation axis extending vertically toward the entrance 141a and the partition portion 143a of the ball extracting member 143, a ball holding portion 144b that is recessed in an arc shape from the rear end of the cutoff portion 144a toward the rotation axis, and a rod-shaped shaft portion 144c that extends downward from the rear end of the ball holding portion 144b. The cutoff portion 144a and the ball holding portion 144b in the ball feeding member 144 are formed adjacent to each other within an angle range of about 180° centered on the rotation axis. The ball holding portion 144b of the ball feeding member 144 is sized to be able to hold one game ball B. The ball feeding member 144 rotates around the rotation axis by moving the shaft portion 144c, which is arranged at an eccentric position with respect to the rotation axis, in the left-right direction by the drive of the ball feeding solenoid 145.

[0250] The ball feeding member 144 is adapted to rotate between a supply position where the blocking portion 144a faces the direction of the partition portion 143a and the ball holding portion 144b faces the direction communicating with the ball supply port 142a, and a holding position where the ball holding portion 144b faces the direction of the partition portion 143a. When the ball feeding member 144 is in the supply position, the game ball B held by the ball holding portion 144b is supplied from the ball supply port 142a to the ball launching device 540, and the game ball B that has entered the partition portion 143a from the entrance 141a is prevented from moving toward the ball holding portion 144b (ball supply port 142a) by the blocking portion 144a, and remains on the partition portion 143a. On the other hand, when the ball feeding member 144 rotates to the holding position, the ball holding portion 144b faces the partition portion 143a, and the end portion of the ball holding portion 144b on the rod portion 144c side closes the ball supply port 142a, and only one game ball B on the partition portion 143a is held in the ball holding portion 144b.

[0251] The ball feeding unit 140 also includes a ball feeding operating rod 146 whose tip swings up and down when driven (energized) by the ball feeding solenoid 145, and a ball feeding crank 147 which rotates around an axis extending in the front-to-back direction due to the movement of the tip of the ball feeding operating rod 146 swinging up and down, and which rotates the ball feeding member 144 around an axis extending in the vertical direction.

[0252] The ball feeding operating rod 146 is provided with an iron plate 146a at a position below the ball feeding solenoid 145. The ball feeding operating rod 146 extends left and right, and the end (right end) opposite the ball feeding crank 147 is attached to the front cover 141 and the rear cover 142 so as to be rotatable around an axis extending forward and backward. When the ball feeding solenoid 145 is driven, the iron plate 146a of the ball feeding operating rod 146 is pulled toward the ball feeding solenoid 145 (upward) by the generated magnetic force, and the left end side close to the ball feeding crank 147 rotates upward around the right end. After that, when the driving of the ball feeding solenoid 145 is released, the magnetic force disappears and the weight of the iron plate 146a acts, rotating the left end side close to the ball feeding crank 147 downward around the right end, returning to the initial state. As a result, the ball feeding operating rod 146 has its left end (tip) near the ball feeding crank 147 swung up and down by the ball feeding solenoid 145.

[0253] The ball delivery crank 147 comprises an engagement portion 147a extending in the left-right direction and capable of engaging with the up-and-down moving tip of the ball delivery operating rod 146, an axle portion 147b arranged on the opposite side of the engagement portion 147a engaging with the ball delivery operating rod 146 and supported rotatably around an axis extending in the front-to-rear direction between the front cover 141 and the rear cover 142, and a transmission portion 147c extending upward from the axle portion 147b and engaging with a rod-shaped rod portion 144c (see Figure 45 (b)) which protrudes downward from a position eccentric to the rotation center of the ball delivery member 144.

[0254] This ball feeding unit 140 can rotate a ball feeding crank 147 around an axis extending forward and backward via the ball feeding operating rod 146 by moving the tip (left end) of the ball feeding operating rod 146 upward by driving the ball feeding solenoid 145.

[0255] When the ball feeding solenoid 145 is not driven (normally), the ball feeding operation rod 146 is separated from the lower end of the ball feeding solenoid 145 and the tip is positioned downward, and in this state, the ball feeding member 144 is positioned in the feeding position. When the ball feeding solenoid 145 is driven, the ball feeding operation rod 146 is attracted to the lower end of the ball feeding solenoid 145 and the tip (left end) is positioned upward, and the ball feeding member 144 rotates to the holding position. In other words, when the ball feeding solenoid 145 is driven (ON state), the ball feeding member 144 receives one game ball B, and when the ball feeding solenoid 145 is deactivated (OFF state), the game ball B received by the ball feeding member 144 can be sent (supplied) to the ball launcher 540 side. The drive of the ball feeding solenoid 145 in this ball feeding unit 140 is controlled in synchronization with the drive control of the firing solenoid 542 by the launch control unit 633b (see Figure 126) of the payout control board 633.

[0256] In addition, the ball feeding unit 140 is configured to receive a moment of rotation in a counterclockwise direction as viewed from the front by the ball removal member 143, which is rotatably supported by the pivot, or the weight portion 143d. However, the rotation of the ball removal member 143 is restricted by the actuation rod 143c protruding forward from the ball removal member 143 coming into contact with the upper end of the actuation transmission portion 242b of the upper tray ball removal slider 242, which is operated by pressing the upper tray ball removal button 222 of the tray unit 200. Therefore, in the normal state, the partition portion 143a of the ball removal member 143 is located between the entrance 141a and the ball removal opening 141b to separate them, and the game ball B does not enter the ball removal opening 141b side.

[0257] When the player presses the upper tray ball removal button 222 of the tray unit 200 downward, the upper tray ball removal slider 242 slides downward together with the actuation transmission part 242b, and the actuation rod 143c also moves downward relatively with the downward movement of the actuation transmission part 242b. When the actuation rod 143c moves downward together with the actuation transmission part 242b, the ball removal member 143 rotates in a counterclockwise direction when viewed from the front, and the partition part 143a moves from between the entrance 141a and the ball removal opening 141b to release the partition. As a result, the game ball B that entered from the entrance 141a falls to the ball removal opening 141b side, and is discharged from the ball removal opening 141b to the ball removal guide path 241c of the upper tray ball removal unit 240 in the tray unit 200, and can be discharged (supplied) to the lower tray 202 through the lower tray ball supply opening 211c.

[0258] Furthermore, the upper tray ball removal slider 242, which forms the operating transmission part 242b with which the operating rod 143c of the ball removal member 143 abuts, is biased upward by a spring. Therefore, even if a game ball B is supplied forcefully onto the partition part 143a, the impact can be absorbed by the spring via the operating rod 143c, preventing damage to the ball removal member 143 etc. and preventing the game ball B from bouncing off the partition part 143a.

[0259] Additionally, ball feeding unit 140 is formed with a rectangular mounting recess 142b (see FIG. 45(b), etc.) recessed forward at the upper right when viewed from behind of ball supply port 142a in rear cover 142, and anti-tampering member 148 is attached within mounting recess 142b. Anti-tampering member 148 of ball feeding unit 140 is formed from a hard metal plate such as tool steel or stainless steel, and is detachably attached from the rear side within mounting recess 142b of rear cover 142.

[0260] The anti-tampering member 148 has an outer shape formed in a rectangular shape extending from left to right when viewed from the front, and includes an upper piece portion 148a and a lower piece portion 148b that are separated vertically at approximately the center in the vertical direction within a predetermined distance to the left from the right side, and an inclined portion 148c that is formed in a C-chamfered shape at the tip side (right end side when viewed from the front) of the opposing sides of the upper piece portion 148a and the lower piece portion 148b. The upper piece portion 148a of the anti-tampering member 148 is bent so that the right end when viewed from the front protrudes backward with respect to the general surface of the anti-tampering member 148. The lower piece portion 148b extends on the same plane as the general surface of the anti-tampering member 148. As a result, the upper piece portion 148a and the lower piece portion 148b form a V-shaped groove that widens toward the right when viewed from the top.

[0261] When the tamper-proof member 148 is attached to the mounting recess 142b of the rear cover 142, the V-shaped groove formed by the upper piece 148a and the lower piece 148b communicates with the inside of the ball supply port 142a.

[0262] According to this fraud prevention member 148, when a fraudulent game ball B with a string attached is shot from the upper tray into the game area 5a by the ball launching device 540 via the ball feeding unit 140, and the string attached to the fraudulent game ball B is manipulated to move the fraudulent game ball B into or out of the first starting hole 2002 or the like, the momentum of the fraudulent game ball B shot (shot) by the ball launching device 540 causes the string attached to the fraudulent game ball B to be inserted between the upper piece 148a and the lower piece 148b, and the string can then be cut by the narrow V-shaped portion formed by the upper piece 148a and the lower piece 148b, thereby preventing fraudulent activities using the fraudulent game ball B with a string attached.

[0263] [3-1j. Foul Cover Unit] The foul cover unit 150 of the door frame base unit 100 will be described in detail mainly with reference to Figs. 46 and 47. Fig. 46(a) is a perspective view of the foul cover unit of the door frame base unit seen from the front, and Fig. 46(b) is a perspective view of the foul cover unit seen from the back. Fig. 47 is a front view of the foul cover unit with the cover member removed. The foul cover unit 150 is attached to the right side of the lower part of the rear side of the door frame base 101 when viewed from the rear. The foul cover unit 150 guides the game ball B (foul ball) that has been shot by the ball launching device 540 and has not reached the game area 5a of the game board 5 to the lower tray 202, and also guides the game ball B that has been paid out from the payout device 580 to the upper tray 201 or the lower tray 202. As shown in the figure, the fall cover unit 150 comprises a shallow box-shaped unit body 151 attached to the rear side of the door frame base 101 and open at the front, and a flat cover member 152 attached to the front of the unit body 151.

[0264] The foul cover unit 150 is equipped with a through ball passage 150a that penetrates from front to back at the upper left corner when viewed from the front, connecting the lower normal payout passage 610a of the lower full ball path unit 610 of the main body frame 4 and the upper tray ball supply port 211a of the tray unit 200, and a full ball receiving port 150b that opens toward the rear on the lower right side when viewed from the front, and is capable of communicating with the lower full payout passage 610b of the lower full ball path unit 610 of the main body frame 4.

[0265] The foul cover unit 150 also has a foul ball receiving port 150c that opens upward on the right side of the full ball receiving port 150b when viewed from the front, and receives game balls B (foul balls) that have been launched by the ball launching device 540 of the main frame 4 but have not reached the game area 5a, and a ball discharge port 150d that opens forward near the lower right corner when viewed from the front, and discharges game balls B received in the full ball receiving port 150b and the foul ball receiving port 150c forward, and is connected to the lower tray ball supply port 211c of the tray unit 200.

[0266] Furthermore, the foul cover unit 150 is provided with a storage passage 150e formed by the unit body 151 and the cover member 152 between the full ball receiving port 150b, the foul ball receiving port 150c, and the ball discharge port 150d, and having a width sufficient to store a predetermined amount of game balls B.

[0267] The through ball passage 150a is formed across both the unit body 151 and the cover member 152. The full ball receiving port 150b and the foul ball receiving port 150c are formed in the unit body 151. The ball discharge port 150d is formed in the cover member 152. The storage passage 150e is formed by the unit body 151 and the cover member 152.

[0268] The fall cover unit 150 also includes a flat plate-shaped movable piece 153 which forms part of the inner wall of the storage passage 150e and whose lower end is rotatably attached to the unit body 151 and the cover member 152, a full tank detection sensor 154 which detects the rotation of the movable piece 153 in a direction away from the storage passage 150e, and a spring 155 which biases the movable piece 153 toward the storage passage 150e.

[0269] When the lower tray 202 of the tray unit 200 is filled with game balls B and the game balls B are no longer discharged from the ball discharge port 150d to the lower tray 202 side, the foul cover unit 150 can store a certain number of game balls B in the storage passage 150e. When a certain number of game balls B are stored in the storage passage 150e, the weight of the game balls B causes the movable piece 153 to rotate so that the upper end of the movable piece 153 moves in a direction away from the storage passage 150e against the biasing force of the spring 155, and the rotation is detected by the full tank detection sensor 154. As a result, it can be determined that the lower tray 202 is full of game balls B, so when the full tank detection sensor 154 detects the full tank, the payout of any more game balls B is stopped and the fact is notified to the player or the attendant of the game hall, and the player can be prompted to clear the full tank of the lower tray 202.

[0270] In addition, the ball cover unit 150 is attached to the lower side of the through ball passage 150a at the rear side of the unit body 151, and is provided with a door opening / closing abutment 150f against which the operating protrusion 613a of the dispensing passage opening / closing door 613 of the lower full ball path unit 610 in the dispensing unit 560 of the main body frame 4 described later can abut (see FIG. 79). The door opening / closing abutment 150f is inclined so that it moves forward as the rear surface faces downward. When the operating protrusion 613a of the dispensing passage opening / closing door 613 abuts against this door opening / closing abutment 150f, the dispensing passage opening / closing door 613 can be rotated to open the downstream ends (front openings) of the lower normal dispensing passage 610a and the lower full dispensing passage 610b.

[0271] [3-2. Glass unit] The glass unit 160 in the door frame 3 will be described in detail mainly with reference to Figures 31 and 32. The glass unit 160 is inserted from the rear into the glass unit attachment portion 101h and detachably attached so as to close the door window 101a of the door frame base 101 in the door frame base unit 100. When the door frame 3 is closed relative to the main body frame 4, this glass unit 160 makes the playing area 5a of the playing board 5 attached to the main body frame 4 visible from the player side (front) and closes the front of the playing area 5a.

[0272] The glass unit 160 comprises a frame-shaped glass frame 161 that is larger than the inner peripheral shape of the door window 101a of the door frame base 101 and can be attached to the glass unit mounting portion 101h, two transparent glass plates 162 that close the inside of the glass frame 161 and have their outer peripheries attached to the glass frame 161, and a pair of glass unit mounting members 163 that are rotatably attached to the rear side of the door frame base 101 in the door frame base unit 100 for mounting the glass frame 161 to the door frame base 101.

[0273] The glass frame 161 has a pair of mounting pieces 161a extending outward in a flat plate shape from positions lower than the upper left and right corners in a front view, and a band-shaped locking piece 161b protruding downward from the lower end and extending along the lower side. The mounting pieces 161a of the glass frame 161 can be brought into contact with the protruding portion 163b of the glass unit mounting member 163. The locking piece 161b can be inserted into the space between the door frame base 101 and the rear flange portion 117c of the intermediate reinforcing frame 117 of the door frame reinforcing unit 110 so as to be placed on the upper flange portion 117b of the intermediate reinforcing frame 117 (see Figures 37 and 85). In this embodiment, the rear surface of the locking piece 161b abuts against the front surface of the rear flange portion 117c. The two glass plates 162 are attached to the front end side and the rear end side of the glass frame 161, respectively, and are spaced apart from each other in the front and rear directions so that a space is formed between them.

[0274] The glass unit mounting member 163 has a disk-shaped base 163a that is rotatably attached around an axis extending forward and backward on the rear side of the door frame base 101, and a rod-shaped protrusion 163b that protrudes from the base 163a in a direction perpendicular to the rotation axis. The glass unit mounting member 163 is rotatably attached to the outside of the two upper corners of the four corners of the door window 101a on the rear surface of the door frame base 101.

[0275] To attach the glass unit 160 to the door frame base 101, first, the glass unit attachment member 163 attached to the door frame base 101 is rotated so that the protruding portion 163b is positioned above the base portion 163a. ​​Then, from the rear side of the door frame base 101, the locking piece 161b of the glass frame 161 of the glass unit 160 is inserted from above into the gap between the door frame base 101 and the rear flange portion 117c of the intermediate reinforcing frame 117 of the door frame reinforcing unit 110 and placed on the upper flange portion 117b, and the front end of the glass frame 161 is abutted against the rear surface of the glass unit attachment portion 101h of the door frame base 101. Then, the glass unit attachment member 163 is rotated so that the protruding portion 163b is positioned below the base portion 163a, and the protruding portion 163b is abutted against the rear surface of the attachment piece 161a of the glass frame 161. This causes the glass unit 160 to be attached to the door frame base 101.

[0276] When removing the glass unit 160 from the door frame base 101, the above-mentioned procedure can be reversed to remove the glass unit 160. In this way, the glass unit 160 is detachable from the door frame base 101 (door frame base unit 100).

[0277] In the glass unit 160, when the protrusion 163b of the glass unit mounting member 163 is in a rotation position located below the base 163a, the protrusion 163b restricts the rearward movement of the glass frame 161, so that even if vibration or the like acts on the glass unit mounting member 163, the protrusion 163b will not rotate to a position where it is above the base 163a. ​​Therefore, the restriction on the rearward movement of the glass frame 161 will not be released naturally, and the glass unit 160 will not come off the door frame base 101 naturally.

[0278] [3-3. Security cover] The security cover 170 in the door frame 3 will be described in detail mainly with reference to Figures 31 and 32. The security cover 170 is attached to the rear side of the door frame base unit 100 so as to cover the lower part of the rear surface of the glass unit 160, and is made of a transparent synthetic resin. The security cover 170 includes a flat body portion 171 having an outer periphery formed into a predetermined shape, a flat rear projection 172 that protrudes rearward along the outer periphery of the body portion 171, and a pair of locking pieces 173 that are spaced apart on the left and right, protrude forward beyond the body portion 171, and are capable of being locked to the rear side of the door frame base 101.

[0279] The main body 171 of the security cover 170 is formed so that the lower end thereof protrudes downward from the lower end of the glass unit 160 when attached to the door frame base unit 100. The upper end of the main body 171 is formed in a shape that conforms to the lower end of the play area 5a of the play board 5 when assembled to the pachinko machine 1. In more detail, the upper end of the main body 171 is formed in a shape that conforms to a part of the inner rail 1002, the out guide part 1003, a part of the lower right rail 1004, and the right rail 1005 of the component member 1000 described later, and is formed so as not to protrude into the play area 5a when assembled to the pachinko machine 1.

[0280] The rear protrusion 172 is formed around substantially the entire circumference of the outer periphery of the main body 171. Therefore, the security cover 170 is formed by the main body 171 and the rear protrusion 172 into a shallow box shape that is open to the rear, and has high strength and rigidity. The rear protrusion 172 also protrudes rearward from a part of the rear surface of the main body 171 that is different from the outer periphery of the main body 171. The rear protrusion 172 protruding rearward from a part of the rear surface of the main body 171 is formed so as to fit along a part of the outer rail 1001 in the front component 1000 of the game board 5 when assembled into the pachinko machine 1.

[0281] In addition, the rear protrusion 172 is not formed in a portion of the game board 5 located between the outer rail 1001 and the inner rail 1002 when assembled in the pachinko machine 1. As a result, the game ball B (the game ball B launched by the ball launcher 540) passing between the outer rail 1001 and the inner rail 1002 does not come into contact with the rear protrusion 172 of the security cover 170, and does not hinder the game ball B from being shot into the game area 5a.

[0282] The pair of locking pieces 173 are elastically locked to the rear side of the door frame base unit 100 (the speaker duct 103 and the cable cover 109). This allows the security cover 170 to be easily attached to and detached from the door frame base unit 100.

[0283] When the security cover 170 is assembled to the pachinko machine 1, the front surface of the main body 171 abuts against the rear surface of the glass unit 160 (the rear end of the glass frame 161), and the rear projection 172 excluding the portion projecting rearward from the bottom edge of the main body 171 is inserted into the security recess 1009 of the front component 1000. Also, the security cover 170 is in a state in which the rear projection 172 projecting rearward from the bottom edge of the main body 171 projects rearward beyond the front surface of the front component 1000 so as to contact the bottom surface of the front component 1000. As a result, the area between the security cover 170 and the game board 5 (front component 1000) is complexly bent by the rear protrusion 172 of the security cover 170 and the security recess 1009 of the front component 1000, so that even if an attempt is made to insert an illegal tool such as a piano wire into the game area 5a between the security cover 170 and the front component 1000 from below the front of the game board 5, the attempt will be blocked by the rear protrusion 172 and the security recess 1009, preventing the illegal tool from entering the game area 5a.

[0284] [3-4a.Handle unit] Next, the handle unit 180 in the door frame 3 will be described in detail with reference to Figs. 48 to 52. Fig. 48 is an exploded perspective view of the handle unit, the plate unit, and the performance operation unit in the door frame as viewed from the front, and Fig. 49 is an exploded perspective view of the handle unit, the plate unit, and the performance operation unit in the door frame as viewed from the rear. Fig. 50 is an exploded perspective view of the handle unit in the door frame as viewed from the front, and Fig. 51 is an exploded perspective view of the handle unit in the door frame as viewed from the rear. Fig. 52(a) is an explanatory diagram showing the relationship between the handle base, the handle, the handle return spring, and the handle touch sensor in the handle unit in a perspective view, and Fig. 52(b) is an explanatory diagram showing the relationship between the handle base, the handle, the handle return spring, the handle touch sensor, and the inner base in the handle unit in a perspective view as viewed from the rear. Note that in Fig. 53, the position of the first mounting portion 190a in the handle return spring 190 is changed for ease of understanding.

[0285] The handle unit 180 in this embodiment is attached to the door frame base unit 100 from the front within the cylindrical handle cover unit 290, and when operated by the player, the game ball B in the upper tray 201 can be shot into the game area 5a of the game board 5.

[0286] The handle unit 180 comprises a handle base 181 whose rear end is attached to the handle mounting surface of the door frame base 101, a handle 197 rotatably attached to the front end of the handle base 181, a disk-shaped cover base 183 attached to the handle base 181 so as to cover the centre of the front end side of the handle 197, a handle decorative board 184 attached to the front side of the cover base 183 and having multiple LEDs 184a mounted on its front side, and a handle front lens 185 attached to the cover base 183 so as to cover the front side of the handle decorative board 184.

[0287] The handle unit 180 also includes an inner base 186 that is attached to the front of the handle base 181 behind the handle 197, an axle member 187 that has the handle 197 attached to its front end and is rotatably attached by the inner base 186 and the handle base 181 and has a drive gear portion 187a on its outer periphery, a transmission gear 188 that meshes with the drive gear portion 187a of the axle member 187, and a handle rotation detection sensor 189 that has a detection shaft 189a that rotates integrally with the transmission gear 188 and is sandwiched between the handle base 181 and the inner base 186.

[0288] Furthermore, the handle unit 180 is equipped with a handle return spring 190 having one end attached to the handle base 181 and the other end attached to the handle 197, urging the handle 197 to return it to its initial rotation position (the end of rotation in the counterclockwise direction when viewed from the front), and an auxiliary spring 191 having one end attached to the inner base 186 and the other end attached to the transmission gear 188, urging the detection shaft 189a of the handle rotation detection sensor 189 in the clockwise direction when viewed from the front via the transmission gear 188.

[0289] The handle unit 180 also includes a handle touch sensor 192 attached to the handle base 181 behind the inner base 186, a single button 193 whose tip side protrudes outward from the left side of the front end outer circumferential surface of the handle base 181 when viewed from the front and whose base end side is attached to the handle base 181 behind the inner base 186 so as to be rotatable around an axis extending forward and backward, and a single button operation sensor 194 attached to the handle base 181 and detects the pressing operation of the single button 193.

[0290] The handle base 181 of the handle unit 180 includes a cylindrical base 181a extending forward and backward, a disk-shaped front end 181b protruding radially from the front end of the base 181a, and three grooves 181c recessed from the outer circumferential surface of the cylindrical base 181a and extending in the axial direction, and formed at unequal intervals in the circumferential direction. The base 181a of the handle base 181 is formed to have an outer diameter slightly smaller than the inner diameter of the rear cylinder of the handle cover base 291 in the handle cover unit 290. The three grooves 181c are formed at positions corresponding to the three protrusions of the handle cover base 291. Therefore, the base 181a can be inserted into the rear cylinder of the handle cover base 291 with the three grooves 181c aligned with the three protrusions, and the handle base 181 cannot rotate relative to the handle cover base 291 by inserting the protrusions into the three grooves 181c.

[0291] The handle base 181 is provided with a sensor accommodating recess 181d in which the handle touch sensor 192 is accommodated from the front, a tab abutment portion 181e with which the tab-shaped terminal 192a of the handle touch sensor 192 abuts, and an attachment hole 181f provided in the tab abutment portion 181e (see FIG. 52). The handle touch sensor 192 is accommodated in the sensor accommodating recess 181d, and the tab-shaped terminal 192a of the handle touch sensor 192 abuts against the tab abutment portion 181e. At the same time, the rear portion of the inner base 186 is inserted into the handle base 181 from the front, and the attachment piece 186a (see FIG. 53) of the inner base 186 is positioned in front of the tab-shaped terminal 192a. Then, by screwing a mounting screw (not shown) into the mounting hole 181f from the front of the mounting piece 186a of the inner base 186 and tightening it, the handle touch sensor 192 can be attached to the handle base 181 together with the inner base 186. At this time, by screwing the mounting screw so that the U-shaped second mounting portion 190b provided on the rear end side of the handle return spring 190 is sandwiched between the mounting piece 186a of the inner base 186 and the tab-shaped terminal 192a of the handle touch sensor 192, the rear end side of the handle return spring 190 can be attached to the handle base 181 and the handle return spring 190 and the handle touch sensor 192 can be electrically connected. The part of the tab abutment portion 181e in the handle base 181 can be seen from the front through a slit 197e in the handle 197, which will be described later, and a screwdriver as a tool can be approached from the front through the slit 197e.

[0292] Handle 197 has a conductive plating layer on its surface. Handle 197 has four projections, a first projection 197a, a second projection 197b, a third projection 197c, and a fourth projection 197d, which protrude outwardly from the outer circumferential surface at a distance in the circumferential direction, two slits 197e which extend in an arc shape about the rotation axis (shaft member 187) and penetrate in the front-rear direction, a spring attachment piece 197f provided at one end of one of the slits 197e in a portion recessed toward the center of handle 197 and facing forward, and an attachment hole 197g which penetrates spring attachment piece 197f in the front-rear direction.

[0293] With the annular first mounting portion 190a provided at the front end of the handle return spring 190 in contact with the upper surface of the spring mounting piece 197f of the handle 197, a mounting screw (not shown) is screwed into the mounting hole 197g from the front and tightened, thereby mounting the front end side of the handle return spring 190 from the front and electrically connecting the plated layer on the surface of the handle 197 to the handle return spring 190. This electrically connects the handle touch sensor 192 and the handle 197 via the metal handle return spring 190, making it possible to detect the touch of the player to the handle 197.

[0294] The four protrusions on the handle 197, that is, the first protrusion 197a, the second protrusion 197b, the third protrusion 197c, and the fourth protrusion 197d, are provided in order in a counterclockwise direction when viewed from the front.

[0295] In this way, according to the handle unit 180 of this embodiment, since both ends of the metal handle return spring 190 that electrically connects the handle touch sensor 192 and the handle 197 are attached by mounting screws, it is possible to reliably connect electrically compared to the case where both ends of the handle return spring 190 are simply in contact, and it is possible to reliably prevent poor contact (detection failure of the handle touch sensor 192). Therefore, even if a chemical solution such as alcohol or sodium hypochlorite used for cleaning in a game hall where this pachinko machine 1 is installed enters the handle unit 180, or gas is generated from the chemical solution and adheres to the handle return spring 190, etc., causing corrosion or oxidation of the surface, poor contact does not occur, and the handle touch sensor 192 can reliably detect the touch of the player.

[0296] Furthermore, in the handle unit 180 of this embodiment, a screwdriver for turning the mounting screws can be approached from the front through the slit 197e of the handle 197 to the first mounting portion 190a and the second mounting portion 190b, which are both ends of the handle return spring 190, making the handle unit 180 easy to assemble and maintain.

[0297] This handle unit 180 is attached to the handle mounting seat of the door frame base 101 via the handle cover unit 290. The handle mounting seat of this door frame base 101 is inclined so that the right end side is located further back than the left end side in a plan view, and faces outward (toward the open side), so the handle unit 180 is also inclined outward in a plan view (in other words, its tip is inclined so as to face the outside of the pachinko machine 1 with respect to a line perpendicular to the front surface of the pachinko machine 1.) and is attached and fixed to the door frame 3. This makes it easy for the player to grip the handle 197 of the handle unit 180, and allows the player to perform a rotation operation without any discomfort.

[0298] [3-4a-1. Modified examples of the handle unit] Next, modified examples of the handle unit will be described. Note that of the multiple modified examples shown below, only one of the modified examples may be used, or multiple modified examples may be used in appropriate combination with the above embodiment.

[0299] (Variation 1) In the above embodiment, the tab-shaped terminal 192a of the handle touch sensor 192 and the second mounting portion 190b of the handle return spring 190 are attached together with a mounting screw, but the present invention is not limited to this. For example, a protrusion may be provided on the handle 197, and the shape of the front end side (first mounting portion 190a) of the handle return spring 190 may be shaped to conform to a part of the outer periphery of the protrusion of the handle 197, so that the front end of the handle return spring 190 is engaged with the protrusion. This makes the front end side of the handle return spring 190 come into line contact with the protrusion, and the contact area increases compared to point contact, making it possible to prevent poor contact. In this case, it is desirable to provide the protrusion of the handle 197 in a location that is unlikely to be exposed to chemicals such as alcohol or sodium hypochlorite used for cleaning. Alternatively, a cover may be provided in the location to prevent chemicals such as alcohol from being applied.

[0300] (Variation 2) Also, for example, a configuration as shown in FIG. 54 may be used. FIG. 54 is an explanatory diagram showing a modified example of the handle unit, in a perspective view from behind, the relationship between the handle base, the handle, the handle return spring, the handle touch sensor, and the inner base. In this modified example, the handle 197 is composed of a main body 197A and an annular ring portion 197B, and the ring portion 197B is formed of metal or resin having a plating layer on its surface. The ring portion 197B of the handle 197 is provided so that the outer circumferential surface is exposed to the outside at the rear end of the handle 197 (the front end of the handle base 181). The ring portion 197B and the handle touch sensor 192 may be electrically connected by an electric wire 198.

[0301] Specifically, one of the round terminals 198a of the electric wire 198, which has round terminals 198a at both ends, is sandwiched between the mounting piece 186a of the inner base 186 and the tab-shaped terminal 192a of the handle touch sensor 192, and is screwed together with them with a mounting screw, and the other round terminal 198a of the electric wire 198 is screwed to the mounting part 197h of the ring part 197B of the handle 197. As a result, when a player grips the handle 197, his / her finger touches the ring part 197B, and the contact can be detected via the ring part 197B and the electric wire 198. Therefore, as in the above, contact failure (detection failure of the handle touch sensor 192) can be reliably prevented, so that even if a chemical solution such as alcohol or sodium hypochlorite is used for cleaning in a game hall where the pachinko machine 1 is installed, contact failure does not occur, and the handle touch sensor 192 can reliably detect the touch of the player.

[0302] Incidentally, ring portion 197B of handle 197 may be fixed to main body portion 197A so as to be rotatable integrally therewith, or may be guided by main body portion 197A or handle base 181 so as to be rotatable relative thereto. In addition, although an annular ring portion 197B has been shown above, a non-annular ring portion 197B that does not go all the way around, such as a C-shape, may also be used.

[0303] In the above, handle 197 is shown as being composed of main body portion 197A and ring portion 197B, but this is not limited to this, and ring portion 197B may be an independent portion having a separate configuration from handle 197.

[0304] (Variation 3) Also, for example, the handle touch sensor 192 may be provided at a different position, and an electric wire 198 having round terminals 198a at both ends may be used, with one round terminal 198a screwed together with the tab-shaped terminal 192a by a mounting screw, and the other round terminal 198a screwed together with the second mounting portion 190b of the handle return spring 190 by a mounting screw. This also makes it possible to reliably prevent poor contact (detection failure of the handle touch sensor 192) in the same manner as above, so that even if chemicals such as alcohol or sodium hypochlorite are used for cleaning in the game hall where the pachinko machine 1 is installed, poor contact will not occur and the handle touch sensor 192 can reliably detect the touch of the player. In this case, the front end side (first mounting portion 190a) of the handle return spring 190 may be attached to the handle 197 by a mounting screw, or may be engaged with a protrusion provided on the handle 197.

[0305] (Variation 4) Also, for example, a mounting hole may be provided on the back surface of the handle 197, one of the round terminals 198a of the electric wire 198 having round terminals 198a at both ends may be screwed together with the tab-shaped terminal 192a of the handle touch sensor 192 with a mounting screw, and the other round terminal 198a may be screwed with a mounting screw screwed into the mounting hole of the handle 197. In this case, the length of the electric wire 198 is set to a length that allows the handle 197 to rotate. As for the portion where the round terminal 198a of the electric wire 198 in the handle 197 is screwed, for example, in the case where the handle 197 has a ring portion 197B as shown in FIG. 54, the ring portion 197B may be provided so as to rotate integrally with the main body portion 197A, and the round terminal 198a may be screwed to a mounting portion 197h of the ring portion 197B. This also ensures that poor contact (detection failure of the handle touch sensor 192) is prevented, as described above. Therefore, even if chemicals such as alcohol or sodium hypochlorite are used during cleaning in the gaming hall in which this pachinko machine 1 is installed, poor contact will not occur and the handle touch sensor 192 can reliably detect the player's contact.

[0306] (Other variations) In the above, the handle 197 is screwed to a plating layer provided on the handle, but the present invention is not limited to this, and for example, if a metal part is provided on the handle 197, the handle touch sensor 192 may be screwed to the metal part and electrically connected to the handle touch sensor 192. As the metal part, the above-mentioned ring part 197B may be made of metal, for example.

[0307] In the above, the handle touch sensor 192 has the tab-shaped terminal 192a, but the present invention is not limited to this and the handle touch sensor may have a connector. In this case, the tip end of the electric wire connected to the connector may be electrically connected to the handle 197 directly or via the handle return spring 190.

[0308] [3-4a-2.Summary] The above-mentioned handle unit 180 has the following technical features. (Technical feature background) A pachinko machine as a gaming machine is provided with a handle operated by a player to launch a gaming ball into a gaming area, and a touch sensor for detecting that the player is touching the handle (for example, Patent Document: JP 2020-137794 A). In conventional gaming machines such as those in the above patent document, the touch sensor and the handle are electrically connected via a spring for returning the handle to its original position, and the touch of the player to the handle is detected. In this type of conventional gaming machine, the end of the spring for returning the handle on the touch sensor side and the end on the handle side are brought into contact with each other using the biasing force of the spring.

[0309] Incidentally, in game halls where gaming machines are installed, chemicals such as alcohol and sodium hypochlorite may be used to clean and disinfect the gaming machines. If the chemicals used for cleaning get into the handles, or if gas is generated and adheres to springs, the surfaces of the springs may corrode or oxidize, causing electrical contact problems. This contact problem may cause the launch of game balls to become unstable or even impossible, reducing the interest of players.

[0310] In view of the above-mentioned circumstances, the following means aims to provide a gaming machine that can reliably detect contact of the handle by a player.

[0311] (Technical solution) Means 1: In the gaming machine, "A gaming machine equipped with a handle unit for launching a gaming ball into a gaming area, The handle unit includes: A rotatable handle; a handle base that rotatably supports the handle; A touch sensor provided on the handle base; The touch sensor has one end screwed together with the electrode tab of the touch sensor, or the tip of an electric wire connected to the electrode tab or the connector of the touch sensor, and the other end is in contact with a plated portion or a metal portion of the handle, and is provided with a metal linear body formed in a linear shape.

[0312] Here, examples of the "linear body" include a "spring" and a "wire".

[0313] According to the configuration of the first means, the game machine is provided with a handle unit for launching game balls into a game area, and the handle unit includes a rotatable handle, a handle base rotatably supporting the handle, a touch sensor provided on the handle base, and a metal linear body having one end screwed together with an electrode tab of the touch sensor or a tip of an electric wire connected to the electrode tab or the connector of the touch sensor, and the other end contacting a plated part or a metal part of the handle and formed into a linear shape. (See the description of Chapter [3-4a. Handle Unit], Figures 50 to 54, etc. in [Mode for Carrying Out the Invention].)

[0314] In this configuration, in a handle unit for launching game balls into a game area, one end of a metal linear body, the other end of which is in contact with a plated or metal part of the handle, is screwed together with an electrode tab of a touch sensor provided on a handle base, or with the tip of an electric wire connected to an electrode tab or a connector of the touch sensor. That is, one end of the linear body is screwed to an electrode tab of the touch sensor, or with the tip of an electric wire electrically connected to the touch sensor via an electrode tab or a connector. As a result, compared to a case in which one end of the linear body is simply in contact without being screwed, even if a chemical solution such as alcohol or sodium hypochlorite used for cleaning the gaming machine penetrates into the handle, or gas is generated and adheres to a spring, etc., causing corrosion or oxidation of the surface, poor contact does not occur, and the touch sensor can reliably detect the touch of a player to the handle via the linear body. Therefore, a gaming machine can be provided that allows players to enjoy the game in good conditions without the launch of the game ball becoming unstable or being unable to launch the game ball due to detection problems with the touch sensor, and that can suppress a decline in the player's interest.

[0315] It is preferable that the touch sensor be attached to the handle base by screwing the electrode tab of the touch sensor, which allows the attachment of one end of the linear body and the touch sensor to be performed simultaneously, thereby reducing the effort required for assembly and disassembly.

[0316] Also, the other end of the linear body may be engaged with a protrusion protruding from the handle. This allows electrical connection by engaging the other end of the linear body with the protrusion of the handle, thereby reducing the effort (man-hours) required for assembling and disassembling the handle unit and suppressing increases in the cost of the gaming machine.

[0317] Furthermore, the other end of the linear body may be screwed to the handle. This makes it possible to make it difficult for poor contact to occur not only at the one end but also at the other end, since the other end of the linear body is screwed to the handle. Therefore, even if the linear body is corroded or oxidized by a chemical solution such as alcohol or sodium hypochlorite when cleaning the gaming machine, poor contact will not occur, and the touch sensor can reliably detect the player's contact with the handle via the linear body.

[0318] Furthermore, when the other end of the linear body is also screwed as described above, it is desirable to be able to approach the screws (mounting screws) at one end and the other end of the linear body from the same direction with a tool such as a screwdriver. This allows both ends of the linear body to be screwed from the same direction, reducing the effort required for assembling the handle unit and suppressing increases in the cost of the gaming machine.

[0319] In addition, it is preferable that the linear body is a spring that biases the handle around the axis. In this way, since the linear body that electrically connects the handle and the touch sensor is the spring that biases the handle, the number of parts of the handle unit can be reduced compared to when the linear body is a member (e.g., an electric wire) separate from the spring, and an increase in the cost of the gaming machine can be suppressed.

[0320] Means 2: In the configuration of Means 1, "The other end of the linear body is engaged with a protrusion protruding from the handle." The present invention is characterized in that

[0321] Here, "protrusion" refers to "something that is integrally molded with the handle," "something that is insert molded into the handle (e.g., a metal pin)," "something that is separate from the handle and attached to the handle (e.g., a metal pin, screw, etc.)," ​​etc.

[0322] According to the configuration of Means 2, the other end of the linear body is engaged with a protrusion protruding from the handle. (See chapter [3-4a. Handle unit] in [Mode for carrying out the invention].)

[0323] As a result, the other end of the linear body is electrically connected by engaging it with the protrusion on the handle, which reduces the effort (man-hours) required for assembling and disassembling the handle unit and suppresses any increase in costs associated with the gaming machine.

[0324] The other end of the linear body may be engaged with a protrusion on the handle and then screwed in. This makes it possible to prevent contact failures from occurring on the other end of the linear body in addition to one end, and the touch sensor can reliably detect the touch of the handle by the player.

[0325] Means 3: In the configuration of means 1 or means 2, "The other end of the linear body is screwed to the handle." The present invention is characterized in that

[0326] According to the configuration of the third aspect, the other end of the linear body is screwed to the handle. (See the description of the handle return spring 190 and FIG. 52 in the [Mode for Carrying Out the Invention].)

[0327] As a result, since the other end of the linear body is also screwed to the handle, contact failure is unlikely to occur not only on one end but also on the other end. Therefore, even if the linear body is corroded or oxidized by chemicals such as alcohol or sodium hypochlorite when cleaning the gaming machine, contact failure will not occur and the touch sensor can reliably detect the player's contact with the handle via the linear body.

[0328] Since one end and the other end of the linear body are screwed, it is desirable to be able to approach each screw (mounting screw) with a tool such as a screwdriver from the same direction. This allows both ends of the linear body to be screwed from the same direction, reducing the effort required for assembling the handle unit and suppressing increases in the cost of the gaming machine.

[0329] Means 4: In any one of the configurations of means 1 to 3, "The linear body is a spring that biases the handle around its axis." It is characterized by:

[0330] According to the configuration of the fourth aspect, the linear body is a spring that biases the handle around its axis. (See the description of the handle return spring 190 in the [Mode for Carrying Out the Invention].)

[0331] As a result, the linear body electrically connecting the handle and the touch sensor is made to be a spring that biases the handle, so that the number of parts in the handle unit can be reduced compared to when the linear body is a separate member from the spring (e.g., an electric wire), and increases in costs associated with the gaming machine can be suppressed.

[0332] In this way, according to the above-mentioned solution, it is possible to provide a gaming machine that can reliably detect the touch of the handle by the player.

[0333] (Relationship between the solution of technical features and embodiments) The handle unit 180 in the door frame 3 of this embodiment corresponds to the handle unit of the above-mentioned solution, the handle base 181 of the handle unit 180 in this embodiment corresponds to the handle base of the above-mentioned solution, the handle return spring 190 of the handle unit 180 in this embodiment corresponds to the linear body and spring of the above-mentioned solution, the handle touch sensor 192 of the handle unit 180 in this embodiment corresponds to the touch sensor of the above-mentioned solution, the tab-shaped terminal 192a of the handle touch sensor 192 in this embodiment corresponds to the electrode tab of the above-mentioned solution, and the handle 197 of the handle unit 180 in this embodiment corresponds to the handle of the above-mentioned solution.

[0334] (Characteristic Effects of the Present Embodiment) According to the pachinko machine 1 of this embodiment, in the handle unit 180 for launching the game ball B in the door frame 3 into the game area 5a, one end side (second mounting part 190b side) of the handle return spring 190 as a metal linear body whose other end side (first mounting part 190a side) is in contact with the plating part of the handle 197 is screwed together with the tab-shaped terminal 192a of the handle touch sensor 192 provided on the handle base 181. In other words, one end side of the handle return spring 190 is screwed to the tab-shaped terminal 192a of the handle touch sensor 192. As a result, compared to a case where one end of the handle return spring 190 is not screwed but simply brought into contact, even if a chemical liquid such as alcohol or sodium hypochlorite used when cleaning the pachinko machine 1 penetrates into the handle unit 180, or gas is generated and adheres to the spring, causing the surface to corrode or oxidize, no contact failure occurs, and the handle touch sensor 192 can reliably detect the player's contact with the handle 197 via the handle return spring 190. Therefore, the launch of the game ball B does not become unstable or the game ball B cannot be launched due to a detection malfunction of the handle touch sensor 192, and the pachinko machine 1 can be provided that allows the player to enjoy the game in good conditions and suppresses a decline in the player's interest.

[0335] In addition, the handle touch sensor 192 can be attached to the handle base 181 by screwing the tab-shaped terminal 192a of the handle touch sensor 192. Therefore, the attachment of one end side (the second attachment portion 190b side) of the handle return spring 190 and the attachment of the handle touch sensor 192 can be performed simultaneously, thereby reducing the effort required for assembly and disassembly.

[0336] Furthermore, since the other end side (first attachment part 190a side) of the handle return spring 190 is screwed to the handle 197, contact failure is unlikely to occur not only at the one end side (second attachment part 190b side) but also at the other end side (first attachment part 190a). Therefore, even if the handle return spring 190 etc. is corroded or oxidized by chemicals such as alcohol or sodium hypochlorite when cleaning the pachinko machine 1, contact failure will not occur, and the handle touch sensor 192 can reliably detect the player's contact with the handle 197 via the handle return spring 190.

[0337] Furthermore, at one end side (the second mounting portion 190b side) and the other end side (the first mounting portion 190a side) of the handle return spring 190, each screw (mounting screw) can be approached with a tool such as a screwdriver from the same direction (the front in this case), and since both ends of the handle return spring 190 can be screwed from the same direction, the effort required for assembling the handle unit 180 can be reduced and the increase in costs associated with the pachinko machine 1 can be suppressed.

[0338] Furthermore, since the linear body electrically connecting the handle 197 and the handle touch sensor 192 is the handle return spring 190 that biases the handle 197, the number of parts in the handle unit 180 can be reduced compared to when the linear body is a separate member (e.g., an electric wire) from the handle return spring 190, and an increase in the cost of the pachinko machine 1 can be suppressed.

[0339] The other end side (first attachment portion 190a side) of the handle return spring 190 may be engaged with a protrusion protruding rearward from the handle 197. This allows the other end side of the handle return spring 190 to be electrically connected by engaging with the protrusion of the handle 197, thereby reducing the effort (man-hours) required for assembling and disassembling the handle unit 180 and suppressing an increase in the cost of the pachinko machine 1.

[0340] [3-4b.Handle cover unit] The handle cover unit 290 in the door frame 3 will be described in detail mainly with reference to Figures 48 and 49. The handle cover unit 290 comprises a handle cover base 291 which covers the outer periphery rearward of the handle 197 in the handle unit 180 and has its rear end attached to the handle mounting seat surface of the door frame base 101, and a handle cover 295 which covers the outer periphery with a gap between it and the handle cover base 291 and has its rear end attached to the dish unit main body 252 of the dish unit 200.

[0341] The handle cover base 291 comprises a cylindrical rear tube portion extending forward and backward with an inner diameter capable of inserting the base 181a of the handle base 181, and multiple (here, three) protrusions protruding inward from the inner circumference of the rear tube portion and extending forward and backward, and provided at positions corresponding to the groove portions 181c of the handle base 181 in the circumferential direction.

[0342] The rear end of the rear cylinder portion is attached to the handle mounting seat surface of the door frame base 101. This rear cylinder portion is formed to have the same length as the base portion 181a of the handle base 181, and the base portion 181a of the handle base 181 is inserted into the rear cylinder portion. The three protrusions correspond to the three groove portions 181c of the handle base 181, and by inserting them into the groove portions 181c, the handle base 181 can be made non-rotatable relative to the handle base 181.

[0343] The handle cover 295 has a front hole 295a at its front end that is larger in diameter than the handle 197, and is formed in a tubular shape resembling a frustum (snow igloo-shaped, bowl-shaped, etc.) that bulges out toward the rear, and is provided with a plurality of (four in this case) notched openings 295b cut out from the rear end toward the front in the circumferential direction. The rear end of the handle cover 295 is attached to the dish unit main body 252 of the dish unit 200.

[0344] Even if liquid such as a drink or a game ball B enters the cylinder, the handle cover unit 290 of this embodiment can discharge it downward through the lower cutout opening 295b.

[0345] Also, the cutout opening 295b on the lower side of the handle cover 295 is provided on an extension line of the inclination direction of the blade portion 46b of the grill member 46 in the outer frame lower assembly 40 of the outer frame 2. This allows the wind (wind pressure) discharged diagonally upward and forward from the grill member 46 via the blade portion 46b due to the vibration of the main frame speaker 622 to enter the cylinder through the cutout opening 295b. Therefore, when a player inserts his / her fingers into the cylinder of the handle cover 295 and rotates the handle 197 (a device for driving in the game ball B), the main frame speaker 622 is vibrated to send wind into the front cylinder portion 291a, surprising the player and allowing an unprecedented performance to be performed. In other words, a sound pressure stimulus can be applied to the fingers of the player operating the handle 197, which can surprise the player, give him a sense of an upcoming opportunity, or cause him to change the amount of handle operation, thereby entertaining the player and preventing him from becoming bored, thereby preventing a decline in interest in the game.

[0346] Furthermore, since sound pressure (sound wind) from the main frame speaker 622 can be supplied into the handle cover unit 290 through the cutout opening 295b, the inside of the handle cover unit 290 can be made cooler. This makes the environment around the player's hands and fingers operating the handle 197 more comfortable, thereby relieving stress on the player and preventing a decline in interest in the game.

[0347] As described above, the sound pressure (sound wind) emitted forward from the port member 47 provided in the outer frame lower assembly 40 of the outer frame 2, which is different from the door frame 3 in which the handle 197 and the handle cover unit 290 are provided, is guided by the multiple blade portions 46b of the grill member 46 to stimulate the fingers of the player who is operating the handle 197 with his / her fingers inserted into the handle cover unit 290. Therefore, compared to a case in which a vibration device is provided in the handle 197, there is no damage to the various sensors (handle rotation detection sensor 189, handle touch sensor 192, single button operation sensor 194, etc.) and bearing mechanism provided in the handle 197, and it is possible to make the handle unit 180 less likely to be damaged, and it is possible to avoid causing discomfort to the player due to damage to the handle unit 180 and suppress a decrease in the player's interest in the game.

[0348] Furthermore, since the handle cover 295 has a cutout opening 295b, when opening the door frame 3 or the main frame 4, the user can hook his / her finger into the cutout opening 295b on the right side and pull it, which can be used as a handle when opening the door frame 3, etc.

[0349] In addition, since the handle cover 295 has the cutout opening 295b, the rotational position of the handle 197 can be easily fixed by gripping the handle 197 and the cutout opening 295b with fingers, and the game ball B can be continuously shot into the game area 5a with a constant strength without continuously twisting the hand. In this way, the game ball B can be shot into the game area 5a by rotating the handle 197 in various ways, so that a pachinko machine 1 can be provided that allows the player to select a shooting operation that suits him / her.

[0350] Furthermore, since the handle 197 is provided in the lower right corner of the door frame 3 on the opposite side to the hinge side, and the cutout opening 295b is provided in a portion facing the right side of the outer peripheral surface of the handle cover 295 of the handle cover unit 290, the cutout opening 295b can be used as a handle for opening and closing the door frame 3. Therefore, there is no need to provide the door frame 3 with a handle that would make it look unattractive, and the appearance of the door frame 3 can be improved.

[0351] [3-5. Overall structure of the plate unit] The tray unit 200 in the door frame 3 will be described in detail mainly with reference to Figures 48 and 49. The tray unit 200 is attached to a portion below the door window 101a on the front side of the door frame base 101 of the door frame base unit 100. The tray unit 200 includes an upper tray 201 for storing game balls B to be shot into the game area 5a, and a lower tray 202 arranged below the upper tray 201 and capable of storing game balls B supplied from the upper tray 201 and the foul cover unit 150.

[0354] The plate decoration unit 250 comprises a lower plate main body 251 which is attached to the lower front part of the plate unit base 211 and has a lower plate 202, a plate unit main body 252 which is attached to the front part of the plate unit base 211 so as to cover the outer periphery of the lower plate main body 251, a lower plate ball removal unit 260 which is attached to the underside of the lower plate main body 251, and a left plate decoration unit 270 and a right plate decoration unit 275 which are attached to the upper front part of the plate unit main body 252, spaced apart from each other on the left and right.

[0355] The performance operation unit 300 is provided with a performance operation section 301 that can be operated by the player, which includes a pressing operation section 303 that can be pressed by the player, a lever operation section 304 that allows the player to operate the lever in the forward and backward directions, and the performance operation section 301 that can be operated by the player. The performance operation unit 300 is provided with a base unit 400 that is attached to the dish base unit 210, and a lever operation section unit 410 that is attached to the base unit 400 so as to be rotatable around an axis that extends in the left-right direction. The pressing operation section 303 is provided on the upper surface of the base unit 400.

[0356] The tray unit 200 bulges forward as a whole, with the performance operation unit 300 positioned in the left-right center so that the top surface of the performance operation unit 301 faces diagonally upward and forward, with the upper tray 201 positioned to the left of the performance operation unit 300 on the top surface and the ball lending operation unit 220 positioned to the right of the performance operation unit 300, and the lower tray 202 positioned below the upper tray 201 and to the left of the performance operation unit 300.

[0357] [3-5a. Upper plate] The upper tray 201 of the tray unit 200 will be described in detail mainly with reference to Figures 48 and 49. The upper tray 201 is formed by a tray unit base 211 and an upper tray body 212, and is formed in a container shape that is open upward and bulges forward more on the left side than the center when viewed from the front. The upper tray 201 (upper tray body 212) bulges forward most at about 1 / 3 of the left end to the right side relative to the left-right width of the door frame 3. The upper tray 201 has a guide passage portion 201a (see Figure 37) whose front end recedes backward as it moves from the most bulging portion to the right when viewed from the front, and whose depth in the front-to-back direction is slightly larger than the outer diameter of the game ball B. The entire bottom surface of the upper tray 201, including the guide passage portion 201a, is inclined so that the right end side is lower, and the right end side of the guide passage portion 201a when viewed from the front is recessed below the ball dispensing operation unit 220.

[0358] When assembled to the tray unit 200, the upper tray 201 has a bottom surface that is inclined downward from a position lower than the upper tray ball supply port 211a of the tray unit base 211 to a position slightly lower than the outer diameter of the game ball B relative to the upper end of the upper tray ball delivery port (not shown). This allows the game ball B released forward from the upper tray ball supply port 211a to be received and stored within the upper tray 201, and the received game ball B can be supplied from the right end side of the guide passage portion 201a through the upper tray ball delivery port to the ball delivery unit 140 side.

[0359] In addition, the guide passage section 201a is equipped with a metal earth fitting that is electrically grounded (earthed) in the pachinko machine 1, and when the game ball B comes into contact with it (rolls), the static electricity charged to the game ball B can be removed.

[0360] [3-5b. Lower plate] The lower tray 202 of the tray unit 200 will be described in detail mainly with reference to Figure 48 etc. The lower tray 202 is located below the upper tray 201, to the left of the left-right center of the tray unit 200 (door frame 3) when viewed from the front. The lower tray 202 is formed of a lower tray main body 251 and a tray unit base 211. The lower tray 202 is formed in the shape of a container capable of storing game balls B, and is provided with a lower tray ball removal hole 202a that penetrates the bottom wall vertically and allows game balls B to be discharged (see Figure 29). The lower tray ball removal hole 202a of the lower tray 202 is closed by a lower tray ball removal lid of the lower tray ball removal unit 260 so as to be able to be opened and closed.

[0361] The lower tray 202 is formed in a generally rectangular shape extending left and right when viewed from above, with the front end on the left side protruding further forward than the right side from the center in the left-right direction. The lower tray 202 has a lower tray ball removal hole 202a that penetrates from top to bottom, located near the front end near the right end. The lower tray 202 is inclined so that the bottom surface is lower toward the lower tray ball removal hole 202a. When assembled to the tray unit 200, the lower tray ball removal hole 202a of the lower tray 202 is located below the performance operation unit 300, to the left of the front of the lower tray ball supply port 211c.

[0362] When the lower tray ball ejection hole 202a is closed, the lower tray 202 can store the game ball B released forward from the lower tray ball supply port 211c, and by opening the lower tray ball ejection hole 202a, the stored game ball B can be discharged below the tray unit 200 (e.g., a cash box). Also, when the lower tray ball ejection hole 202a of the lower tray 202 is open, since the lower tray ball ejection hole 202a is disposed in front of the lower tray ball supply port 211c, the game ball B released forward from the lower tray ball supply port 211c can be quickly discharged downward from the lower tray ball ejection hole 202a by moving the shortest distance.

[0363] [3-5c. Dish base unit] The dish base unit 210 in the dish unit 200 will be described in detail mainly with reference to Figures 48 and 49.

This allows the game ball B paid out from the payout device 580 of the payout unit 560 to be supplied (paid out) into the upper tray 201 through the upper tray ball supply port 211a.

[0368] When assembled to the door frame 3, the lower tray ball supply port 211c has a front end that opens into the rear wall of the lower tray 202, and a cylindrical rear end that penetrates the lower tray ball passage port 101f of the door frame base 101 from the front side and connects to the front end of the ball discharge port 150d of the foul cover unit 150. As a result, the game ball B circulating in the storage passage 150e of the foul cover unit 150 is supplied into the lower tray 202 through the lower tray ball supply port 211c. In addition, the downstream end of the ball removal guide path 241c in the rear base 241 of the upper tray ball removal unit 240 is connected to the cutout portion 211d formed in the cylindrically extending portion of the lower tray ball supply port 211c. As a result, by operating the upper tray ball removal button 222, the game ball B stored in the upper tray 201 is discharged from the lower tray ball supply port 211c into the lower tray 202 through the upper tray ball supply port, the entrance 141a and ball removal port 141b of the ball supply unit 140, the ball supply guide path and ball removal guide path 241c of the upper tray post-ball removal unit 240, and the cutout portion 211d.

[0369] When assembled to the tray base unit 210, the upper tray ball supply port is located in front of the ball receiving port (not shown) of the rear base 241 in the upper tray ball removal unit 240, and the game ball B in the upper tray 201 is supplied from the ball receiving port of the upper tray ball removal unit 240 to the ball supply guide path.

[0370] [3-5c-2. Upper plate body] The upper tray body 212 of the tray base unit 210 will be described in detail mainly with reference to Figures 48 and 49. The upper tray body 212 is attached to the front of the tray unit base 211 and cooperates with the tray unit base 211 to form the upper tray 201. The upper tray body 212 is formed in a container shape (dish shape) with an open top and rear. The upper tray body 212 extends left and right, and the left side bulges forward more than the center left and right when viewed from the front. The front end of the upper tray body 212 retreats rearward from the most forward bulging part toward the right when viewed from the front, and the depth in the front-to-rear direction is formed to a width slightly larger than the outer diameter of the game ball B. The bottom surface of the upper tray body 212 is inclined so that the right end is the lowest. The upper part of the upper tray body 212 near the right end is closed.

[0371] When the upper tray body 212 is assembled to the tray unit 200, the portion that is closed at the top near the right end is attached so that it fits under the ball lending operation unit 220. In addition, the upper tray body 212 has a performance operation unit attachment portion 212a formed in the middle of the upper part in the left-right direction, and a part of the performance operation unit 300 is attached to this performance operation unit attachment portion 212a.

[0372] [3-5c-3. Dish unit relay board] The dish unit relay board 214 of the dish base unit 210 is intended to relay the connection between the door frame sub-relay board 105 (see Figure 72) in the door frame base unit 100 and the left dish decorative board, right dish decorative board, and rotating body decorative board 416, etc. The dish unit relay board 214 is attached near the lower right corner of the rear surface of the dish unit base 211. When attached to the dish unit base 211, this dish unit relay board 214 has its rear surface facing the rear side of the dish unit base 211.

[0373] [3-5c-4. Ball lending operation unit] The ball dispensing operation unit 220 of the tray base unit 210 will be described mainly with reference to Figures 48 and 49. This ball dispensing operation unit 220 is for discharging game balls B stored in the upper tray 201 to the lower tray 202, dispensing a predetermined number of game balls B into the upper tray 201 of the tray unit 200 after inserting cash or a prepaid card into a ball dispensing machine (not shown) installed adjacent to the pachinko machine 1, displaying the remaining amount of cash or a prepaid card inserted into the ball dispensing machine, returning the cash or a prepaid card inserted into the ball dispensing machine minus the amount of the dispensed game balls B, adjusting the volume, and adjusting the amount of light.

[0374] The ball lending operation unit 220 includes an upper tray ball removal button 222, a ball lending button 224, a return button 225, a ball lending display unit 226, and an adjustment button 229 consisting of four buttons arranged in a cross shape.

[0375] The upper tray ball removal button 222 protrudes upward in a cylindrical shape, and can be moved downward when the player presses it. The ball lending button 224 is formed in a circular shape, and the character "ball" (ball) is inscribed on the upper surface. The return button 225 is formed in a triangular shape. The ball lending display unit 226 is composed of three 7-segment LEDs and one bullet-shaped LED, and can be clearly seen by the player when illuminated.

[0376] The ball lending operation unit 220 can discharge game balls B stored in the upper tray 201 to the lower tray by pressing the upper tray ball removal button 222. Furthermore, when cash or a prepaid card with a remaining balance is inserted into the ball lending machine and the ball lending button 224 is pressed, a predetermined number of game balls B are supplied to the upper tray 201. When the return button 225 is pressed, the amount of the lent game balls B is deducted from the cash or prepaid card inserted into the ball lending machine and returned. The ball lending display unit 226 displays the remaining amount of cash or prepaid card inserted into the ball lending machine. Furthermore, the ball lending display unit 226 displays an error code when the ball lending machine breaks down.

[0377] The adjustment button 229 is used to adjust the volume of the music, voice, sound effects, and other sounds for the performance output from the top center speaker and top side speaker of the door frame 3 and the low-frequency main frame speaker 622 of the main frame 4, and to adjust the light intensity (brightness) of the LEDs of the various decorative boards provided on the door frame 3 and the game board 5, and the brightness of the display screen of the performance display device 1600, etc.

[0378] By the way, when the volume or light intensity is adjusted using the pressing operation unit 303 of the performance operation unit 301, when a player participation type performance that requires the operation of the performance operation unit 301 is not being performed, the performance operation unit 301 is operated appropriately to display a setting menu for adjusting the volume or light intensity on the performance display device 1600, and an item to be adjusted is selected, and then the pressing operation unit 303 or the lever operation unit 304 is operated to change the volume or brightness of the light intensity, etc., which takes time (time) to adjust the volume or light intensity. In contrast, according to this embodiment, the volume or light intensity can be directly adjusted by operating the adjustment button 229, and a pachinko machine 1 can be provided that simplifies the time required for adjusting the volume or light intensity and allows adjustment in a short time.

[0379] [3-5c-5. Upper tray ball removal unit] The upper tray pre-ball removal unit and upper tray post-ball removal unit 240 in the tray base unit 210 will be described in detail mainly with reference to Figure 49. The upper tray post-ball removal unit 240 cooperates with the ball delivery unit 140 to discharge the game balls B stored in the upper tray 201 to the lower tray 202 when the upper tray ball removal button 222 of the ball lending operation unit 220 is pressed.

[0380] The upper tray ball removal unit 240 comprises a rear base 241 attached to the rear surface of the tray unit base 211 so as to close the upper tray ball supply port from the rear, an upper tray ball removal slider 242 attached to the front surface of the rear base 241 so as to be slidable in the vertical direction, a spring (not shown) that biases the upper tray ball removal slider 242 upwardly, and a rear cover 244 attached to the rear side of the rear base 241.

[0381] The rear base 241 is equipped with a ball receiving opening (not shown) that protrudes upward from the portion where the upper tray ball removal slider 242 is slidably attached and opens toward the front, allowing the game ball B to pass through, a ball feed guide path that guides the game ball B received in the ball receiving opening downward on the rear surface of the rear base 241 and then rearward, and a ball removal guide path 241c that guides the game ball B downward from a position lower than the ball feed guide path on the rear surface of the rear base 241 and then guides it to the right when viewed from behind.

[0382] The ball receiving port is formed at a position that opens forward through the upper tray ball supply port of the tray unit base 211 at the downstream end (right end when viewed from the front) of the guide passage section 201a of the upper tray 201 when assembled to the tray base unit 210. The ball supply guide path is formed so that the entrance 141a of the ball supply unit 140 is located at the rear of the lower part when assembled to the door frame 3. This allows the game ball B supplied to the upper tray 201 to enter the entrance 141a of the ball supply unit 140 through the ball receiving port and the ball supply guide path.

[0383] The left and right extending portion of the ball removal guideway 241c protrudes further to the right in rear view than the portion where the upper tray ball removal slider 242 is slidably attached, is inclined so that the right end side in rear view is lower, and opens to the right side in rear view. The rear side of the left and right extending portion of the ball removal guideway 241c is closed by the rear cover 244. When assembled to the door frame 3, the ball removal guideway 241c is formed so that the upper part of the portion extending vertically below the ball feeding guideway is located in front of the ball removal opening 141b of the ball feeding unit 140, and the right end of the left and right extending portion in rear view is connected to the cutout portion 211d of the lower tray ball supply opening 211c in the tray unit base 211. As a result, the game ball B discharged from the ball removal port 141b of the ball feeding unit 140 is released into the lower tray 202 from the lower tray ball supply port 211c via the ball removal guide path 241c and the cutout portion 211d.

[0384] The upper tray ball removal slider 242 is formed in a square shape when viewed from the front, and includes an actuation receiving part (not shown) protruding forward from the upper left corner, and an actuation transmitting part 242b protruding rearward from the rear surface of the actuation receiving part. The actuation receiving part has a flat upper surface. The actuation transmitting part 242b is inclined so that the upper surface is positioned downward as it approaches the rear, and the lower surface extends horizontally so as to connect with the rear end of the upper surface.

[0385] When the upper tray ball removal slider 242 is assembled to the door frame 3, the actuation receiving portion protrudes forward through the tray unit base 211 from the rear side, and the lower end of the upper tray ball removal button 222 abuts against the upper surface of the actuation receiving portion. Also, when the upper tray ball removal slider 242 is assembled to the door frame 3, the actuation transmission portion 242b protrudes rearward from the rear base 241, and the actuation rod 143c of the ball removal member 143 of the ball feeding unit 140 abuts against the upper surface.

[0386] The spring has an upper end attached to the rear base 241 and a lower end attached to the upper tray ball removal slider 242, and urges the upper tray ball removal slider 242 upward. Therefore, the upper tray ball removal slider 242 is positioned at the upper limit of its upward movement due to the urging force of the spring, and can move downward by resisting the urging force of the spring.

[0387] The upper tray ball removal unit 240 positions the upper tray ball removal slider 242 at its upward end of movement due to the biasing force of the spring, and positions the upper tray ball removal button 222 at its upward end of movement via the actuation receiving part of the upper tray ball removal slider 242. In addition, because the upper tray ball removal slider 242 is positioned at its upward end of movement due to the biasing force of the spring, the actuation rod 143c abutting against the upper surface of the actuation transmission part 242b is prevented from moving downward, and the partition part 143a of the ball removal member 143 is positioned between the entrance 141a and the ball removal opening 141b, separating the two.

[0388] Therefore, when the upper tray ball removal button 222 is not pressed, the entrance 141a and the ball removal port 141b in the ball feeding unit 140 are partitioned, and the game ball B sent from the upper tray 201 to the ball receiving port can be sent from the entrance 141a and the ball feeding member 144 through the ball supply port 142a to the ball launching device 540 side.

[0389] On the other hand, when the upper tray ball removal button 222 is pressed downward against the spring force, the upper tray ball removal slider 242 moves downward, and the operating rod 143c of the ball removal member 143 that is in contact with the upper surface of the operating transmission part 242b of the upper tray ball removal slider 242 can move downward, and the ball removal member 143 rotates due to the load of the weight part 143d of the ball removal member 143, and the partition part 143a retreats from between the entrance 141a and the ball removal opening 141b. As a result, the game ball B that entered the entrance 141a from the upper tray 201 through the ball receiving opening and the ball delivery guideway is discharged forward from the ball removal opening 141b that opens below the entrance 141a. Then, the game ball B discharged forward from the ball removal opening 141b passes through the ball removal guide path 241c and is guided through the cutout portion 211d into the lower tray ball supply opening 211c, and is then released from the lower tray ball supply opening 211c into the lower tray 202, and the game ball B in the upper tray 201 is discharged into the lower tray 202.

[0390] When the downward pressure on the upper tray ball removal button 222 is released, the upper tray ball removal slider 242 moves upward due to the spring force, the upper tray ball removal button 222 rises, and the ball removal member 143 rotates due to the operating rod 143c abutting the operating transmission part 242b, so that the partition part 143a is positioned between the entrance 141a and the ball removal opening 141b, returning to the original state.

[0391] In this way, the upper tray ball removal unit 240 can feed the game ball B in the upper tray 201 to the ball launching device 540 side via the ball feeding unit 140, or discharge it to the lower tray 202 side.
