Technical Field

[0005] The present invention relates to a safe electronic boot for a casino for storing a plurality of game cards that are drawn one by one for a game. Background Art

[0006] In a casino, games using game cards are played on a gaming table. The game cards for the game are stored in a shoe on the gaming table. The shoe can store, for example, 8 decks of game cards. A dealer can play the game by drawing game cards one by one from the shoe.

[0007] When the game cards stored in the shoe are exhausted as the game progresses, the dealer loads new game cards into the shoe. Specifically, when the dealer loads game cards into the shoe, a stop card is inserted at a position slightly in front of the most distal end of the already loaded game cards. If the stop card is drawn as the game progresses, the dealer leaves the remaining game cards in the shoe and directly interrupts the subsequent game, and then removes the remaining game cards from the shoe and loads new game cards.

[0008] The game cards loaded into the shoe are packaged in a pre-shuffled state. When loading new game cards into the shoe, it is necessary to open the card pack, then take out a plurality of (e.g., 8 decks) shuffled game cards and store them in the shoe. Summary of the Invention

[0009] Since the game cards stored in the shoe are used for games in a casino, the details and arrangement order of the game cards stored in the shoe cannot be known to anyone. That is, a high level of security is required for casino shoes. In particular, when taking out multiple game cards after opening a card pack and loading them into the shoe, it is necessary to keep the details of the game cards unknown to players or dealers.

[0010] In addition, during the period of loading new game cards into the shoe, the game must be interrupted. If the interruption time is long, the game participants will feel bored and the turnover of the casino will also decline. Therefore, it is desired that the loading of game cards into the shoe can be carried out smoothly.

[0011] An object of the present invention is to provide a safe electronic shoe for a casino that can ensure security and smoothly load game cards.

[0066] Hereinafter, the electronic shoe of the embodiment of the present invention will be described. In this embodiment, a casino safety electronic shoe (hereinafter, simply referred to as "electronic shoe") used on a gaming table in a casino for storing multiple game cards that are drawn one by one by a dealer for playing games will be described. This electronic shoe is used on a gaming table in a casino. The game can be, for example, a certain card game. In this embodiment, the electronic shoe used for this card game will be described.

[0067] (First Embodiment)

[0068] Figure 1 Is a perspective view of the electronic shoe of the first embodiment of the present invention, Figure 2 Is a side view of the electronic shoe of the first embodiment of the present invention, Figure 3 Is a top view of the electronic shoe of the first embodiment of the present invention, Figure 4 Is a front view of the electronic shoe of the first embodiment of the present invention. The electronic shoe 100 as a whole has a rectangular parallelepiped shape. The electronic shoe 100 stores multiple game cards in such a way that its short side is parallel to the long side of the game card. The game cards are drawn one by one from the front end of the electronic shoe 100 to the outside of the electronic shoe 100 by the extraction operation of the dealer.

[0069] The electronic shoe 100 includes a storage portion 10, an opening portion 20, a drawing guide portion 30, a hammer body 40, and a main body 50. The lower half and the rear portion of the electronic shoe 100 form the main body 50. The storage portion 10 is continuously extended forward from the rear end portion of the main body 50. The storage portion 10 stores a plurality of stacked game cards. As described above, the plurality of stacked game cards are horizontally stored in the storage portion 10. The long sides of the game cards are supported on the bottom surface of the storage portion 10. In addition, the game cards are stored in the storage portion 10 with their backs facing forward.

[0070] The bottom surface 11 of the storage portion 10 is inclined so as to descend toward the opening portion 20. The storage portion 10 has a structure with its upper surface and left side surface (i.e., the right side when facing the direction in which the game cards are drawn out) open. That is, the right side surface of the storage portion 10 has a side wall 12 with a height corresponding to the height of the stored game cards (the length of the short side of the game cards). On the left side surface, a relatively low side wall 14 is also erected from the bottom surface 11. In addition, the side wall 14 is formed to have a height corresponding to the height of the stored game cards at a portion close to the opening portion 20.

[0071] The relatively low portion of the side wall 14 is a side surface opening portion of the left side surface, and an upper surface opening portion that is continuous with the side surface opening portion and opens the storage portion 10 upward is formed. Through the side surface opening portion and the upper surface opening portion, a plurality of game cards can be loaded into the storage portion 10.

[0072] Figure 5 It is a diagram showing a situation where a plurality of game cards are loaded into the electronic shoe according to the first embodiment of the present invention. A plurality of game cards are stored in a card pack P after being shuffled in advance. The card pack P is sealed and is unsealed by the dealer when loaded into the electronic shoe 100. Figure 5 The shown card pack P has the upper half portion corresponding to a plurality of game cards removed, and only the lower half portion stores a plurality of game cards.

[0073] As Figure 5 As shown, the dealer inserts a plurality of game cards stored in the card pack P that is only half into the storage portion 10 from the side surface opening portion and the upper surface opening portion. At this time, after the dealer places the card pack P with the game cards on the side surface opening portion and fixes it at once, while pulling out the card pack P, the dealer neatly stores the plurality of game cards in the storage portion 10 by abutting against the side wall 12 inside the storage portion 10.

[0074] The side walls 14 with a relatively low height are formed at the positions of the lower parts of the multiple game cards relative to the side opening part, and function as stoppers for restricting the lateral movement of the multiple game cards stored therein. Thereby, even when the side cover 13 is in the open state, the game cards are neatly stored in the storage part 10, the game cards do not move left and right or up and down, and the game cards do not fly out of the storage part 10. Further, as described later, the hammer body 40 presses the lowermost game card toward the opening part 20, so that the game cards move sequentially in the front-rear direction as they are sequentially drawn out from the front end, and thus do not fly out of the storage part 10.

[0075] The storage part 10 is provided with a side cover 13 which has a shaft on the outer side of the side wall 14 formed at a relatively low position. The side cover 13 rotates between a covering position and an open position by rotating about this shaft. When in the covering position, the side cover 13 is in an upright posture, closes the side opening part, and covers the stored game cards. When in the open position, the side cover 13 is in a posture that rotates further than the horizontal posture and opens the side opening part.

[0076] The opening part 20 exposes the foremost game card among the multiple game cards stored in the storage part 10 to the outside. The opening part 20 is formed in an arch shape and exposes the central part of the back surface of the game card. The dealer can draw out the foremost game card with its back facing up onto the gaming table by pressing the exposed part downward and sliding it.

[0077] A curtain 21 is formed at the opening part 20 to cover the back surface of the foremost game card exposed from the opening part 20. The curtain 21 is composed of a plurality of flexible thin wire-like members and is separated left and right at the center. The wire-like members are arranged to be inclined toward the drawing-out direction from left and right toward the center and from the root toward the front end. The dealer can apply a force to the game card from near the left-right separation of these wire-like members to draw out the game card.

[0078] The drawing guide part 30 guides the foremost game card to be drawn out from the opening part 20. Specifically, the drawing guide part 30 includes: an inclined part 32 which is inclined so as to connect from the opening part 20 to the upper surface of the gaming table; and a restricting part 31 which guides the game card to move in the drawing-out direction by restricting the upward and lateral movement of the drawn game card. The game card is drawn out while being guided by the drawing guide part 30, and the front surface printed with the face value and suit is drawn out onto the gaming table with the face facing downward. Fine embossing is applied to the inclined part 32, whereby the front surface of the game card easily slides.

[0079] Figure 6This is a diagram showing the structure of the hammer body according to the first embodiment of the present invention. The hammer body 40 is used to push the lowermost game card among multiple game cards toward the opening 20. The hammer body 40 has a roller 41 with a lateral axis. The lower end of the roller 41 slightly protrudes from the bottom surface of the hammer body 40. Thus, by rotating the roller 41, the hammer body 40 can move in the front-rear direction.

[0080] The lateral width of the hammer body 40 corresponds to the lateral width of the storage portion 10. In addition, the hammer body 40 has an inclined surface 42 in front of it. As described above, the game cards are stored in the storage portion 10 with their backs facing the opening 20, so the front surface of the lowermost game card abuts against the inclined surface 42 of the hammer body 40.

[0081] The hammer body 40 can move back and forth along the bottom surface 11 of the storage portion 10. As described above, the storage portion 10 is inclined toward the opening 20, so the hammer body 40 moves toward the opening 20 due to its own weight. When multiple game cards are loaded in the storage portion 10, the inclined surface 42 of the hammer body 40 pushes the lowermost game card toward the opening 20. In this way, due to the action of the hammer body 40, the foremost game card is always pushed from the rear to the opening 20 and thus exposed from the opening 20.

[0082] The hammer body 40 can be fixed to the rear position of the storage portion 10 by a magnet or a locking mechanism. As Figure 5 shown, when loading the game cards into the storage portion 10, the hammer body 40 is fixed at this fixed position, and a space is formed in the storage portion 10 capable of storing a new set of multiple game cards. Further, by detecting that multiple game cards are stored in the storage portion 10 by a sensor, based on the detection of this sensor, the fixation of the magnet or the locking mechanism on the hammer body 40 can be automatically released. If the fixation is released, the hammer body 40 moves toward the opening 20 along the bottom surface 11 of the storage portion 10 due to its own weight, abuts against the lowermost game card, and pushes the loaded multiple game cards from the lowermost to the opening 20. It should be noted that, for example, by detecting that the side cover 13 closes the side opening or the upper surface cover 15 described later closes the upper surface opening, the situation that the game cards are stored in the storage portion 10 can be detected.

[0083] It should be noted that the roller 41 of the hammer body 40 can be configured to be rotatable only in the direction that makes the hammer body 40 move forward (the side with the inclined surface 42), and not rotatable in the direction that makes the hammer body 40 move backward. Thus, when the game cards are sequentially drawn out from the foremost end, even if a force is applied to the hammer body 40 in the backward direction, the hammer body 40 will not move backward.

[0084] The upper surface portion of the main body 50 is provided with a plurality of result display lights 52. In addition, a result display button 53, a result display light 54, and a result display 55 are provided on the left side surface of the main body 50.

[0085] The side opening portion, the side cover 13, and the result display button 53 are all provided on the side facing the dealer when the electronic shoe 100 is placed on the gaming table. That is, since the electronic shoe 100 is placed on the left side of the dealer, the side opening portion and the result display button 53 are provided on the left side facing the dealer. Thus, it is easy for the dealer to operate the result display button 53 of the electronic shoe 100 placed on the gaming table and to load new game cards into the storage portion 10 from the side opening portion.

[0086] In addition, the result display 55 is also provided on the left side facing the dealer. Thus, the game result can be shown to the dealer without being seen by the players.

[0087] Figure 7 is a perspective view of the electronic shoe according to the first embodiment of the present invention, Figure 8 is a side view of the electronic shoe according to the first embodiment of the present invention, Figure 9 is a top view of the electronic shoe according to the first embodiment of the present invention. In Figures 7 to 9 the electronic shoe, the side cover 13 closes the side opening portion, and the upper surface cover 15 is mounted on the storage portion 10 and closes the upper surface opening portion.

[0088] In this way, by covering the side with the side cover 13 and the upper surface with the upper surface cover 15, the game cards stored in the storage portion 10 are completely invisible, ensuring safety. As described above, the side cover 13 can rotate about a rotation axis provided at the lower portion, so that it can pivot between the open position shown in Figure 1 and the covering position shown in Figure 7 If the side cover 13 is rotated and located at the covering position, the side wall 12 on the right side and the side cover 13 are both upright, and their upper ends become the slide rails of the upper surface cover 15.

[0089] In this way, since the upper end of the side cover 13 becomes the slide rail of the upper surface cover 15 when the side cover 13 is located at the covering position, in order to make the upper surface cover 15 located at the covering position, first, the side cover 13 needs to be made upright and located at the covering position covering the side. In other words, the structure is such that the upper surface cover 15 cannot be closed unless the side cover 13 is closed.

[0090] The upper surface cover 15 moves to the covering position shown in Figure 7 by sliding backward along the slide rail from the front. Thus, by installing the upper surface cover 15, the side cover 13 is also fixed at the covering position.

[0091] The electronic shoe 100 may also be provided with sensors (not shown) for detecting that the side cover 13 and the upper surface cover 15 are respectively in the covering positions. The sensors may use magnets or optical sensors. When the sensors do not detect that the side cover 13 and the upper surface cover 15 are in the covering positions, the control device of the electronic shoe 100 outputs an error signal.

[0092] When it is detected by the sensors that the side cover 13 and the upper surface cover 15 are not in the covering positions, the electronic shoe 100 actuates the extraction restricting pin 38 described later, thereby prohibiting the extraction of the game cards.

[0093] Figure 10 is a sectional view taken along line A-A of Figure 9 . As shown in Figure 10 , the bottom surface of the storage portion 10 supports the long side of the game card C, and the side wall 14 functions as a stopper and abuts against the short side of the game card C to restrict the lateral movement of the game card C. The side cover 13 is continuous with the lower-formed side wall 14 and is located above the side wall 14, but the inner surface of the side cover 13 in the covering position is located slightly more outward than the inner surface of the side wall 14. That is, a gap g is formed between the inner surface of the side wall 14 and the inner surface of the side cover 13 in the covering position.

[0094] With this structure, the plurality of game cards that move toward the opening 20 in the storage portion 10 due to the sequential extraction of the game cards from the foremost end are not restricted in movement by the side cover 13 protruding from the side wall 14, and thus can move toward the opening 20.

[0095] Figure 11 is a diagram showing details of the extraction guiding portion of the first embodiment of the present invention. In Figure 11 , the internal structure of the restricting portion 31 with a part of the restricting portion 31 removed is shown. The inside of the restricting portion 31 includes: a code reading sensor 33 and a code reading sensor 34 for reading codes representing at least the numerical values (card face values) of the shuffled game cards; and a card detection sensor 35 and a card detection sensor 36 for detecting that the game card C has been extracted.

[0096] It should be noted that the restricting portion 31 of the extraction guiding portion 30 is detachable, and in addition, the extraction guiding portion 30 may also be detachable from the opening 20. Thus, various maintenance can be performed.

[0097] Figure 12 is a diagram showing an example of the game card of the first embodiment of the present invention. Markings M1 and M2 representing code information are printed on the game card at positions corresponding to the code reading sensor 33 and the code reading sensor 34. Both the markings M1 and M2 are printed with UV ink that cannot be visually confirmed under natural light.

[0098] The code reading sensor 33 and the code reading sensor 34 each have a lamp for irradiating ultraviolet rays and a sensor for reading a mark. Marks M1 and M2 representing code information are formed in two sections at the end of the short side of the card. The two rows of marks M1 and M2 are printed in multiple columns to form code information. The code information is represented by the combination of the presence or absence of marks M1 and M2.

[0099] The code reading sensor 33 reads the mark M1, and the code reading sensor 34 reads the mark M2. The electronic shoe 100 reads the code information based on the combination of the read marks M1 and M2. The code reading sensor 33 and the code reading sensor 34 obtain the code information by sequentially reading the marks M1 and M2 of the drawn game card in the drawing direction. The code information represents the face value of the game card C. Thus, the electronic shoe 100 can determine the face value of the drawn game card C.

[0100] The electronic shoe 100 determines the game result based on the determined face value of the card. The game result is any one of Player Win, Banker Win, and TIE. If the game result display button 53 is pressed, the corresponding lamp in the result display lamp 52 is lit according to the determined game result.

[0101] The six result display lamps 52 respectively correspond to the game results of Player Win, Banker Win, TIE, Player Pair, Banker Pair, and Banker. If the game result display button 53 is pressed again while the result display lamp 52 is lit, the result display lamp 52 goes out and prepares for the next game.

[0102] The card detection sensors 35 and 36 are fiber optic sensors for detecting the presence or absence of the game card C. The card detection sensors 35 and 36 are separately provided before and after in the card drawing direction. If a card is drawn, first, only the card detection sensor 35 is turned on, then the card detection sensors 35 and 36 are turned on, then only the card detection sensor 36 is turned on, and finally, the card detection sensors 35 and 36 are turned off.

[0103] If the card detection sensors 35 and 36 are not turned on or off in this order, it can be considered that the game card C has moved backward. In this case, the electronic shoe 100 determines that the card has been drawn incorrectly and lights the corresponding error display lamp 51.

[0104] The extraction guide portion 30 is further provided with a restricting rod 37 for preventing two game cards from being extracted simultaneously. The restricting rod 37 is configured as a metal piece. The restricting rod 37 is provided on both sides of the extraction guide portion 30.

[0105] Figure 13 FIG. is a diagram showing the function of the restricting rod according to the first embodiment of the present invention. A gap through which only one game card can pass is provided between the restricting rod 37 and the inclined portion 32. The restricting rod 37 functions to press a game card C being extracted while sliding along the inclined portion 32 from above.

[0106] In Figure 13 even if the second game card C2 is pulled forward as the foremost game card C1 is extracted, since the foremost game card C1 passes between the restricting rod 37 and the inclined portion 32, the foremost game card C1 is pressed against the inclined portion 32, and the second game card C2 cannot move forward any further, thereby preventing two cards from being extracted.

[0107] The extraction guide portion 30 is further provided with an extraction restricting pin 38. The extraction restricting pin 38 is buried under the inclined portion 32 in a state where the game card C can be extracted, and protrudes from the inclined portion 32 in a state where the game card C cannot be extracted, and restricts the extraction of the game card C.

[0108] In a card game, the game result is determined based on the face values of the game cards extracted in sequence. Whether the 5th and 6th cards should be extracted is determined based on the face values of the first 4 cards extracted. Therefore, the electronic shoe 100 can determine the end of the game based on the face values of the game cards C extracted in sequence.

[0109] If the game ends, the dealer presses the result display button 53 to turn on the result display lamp 52, and further presses the result display button 53 to turn off the result display lamp 52 and start the next game. After the game ends (the game result is determined), by pressing the result display button 53 twice, before the next game starts, the extraction of the game card is prohibited.

[0110] The extraction restricting pin 38 protrudes in such a prohibited extraction state and prevents the extraction of the prohibited game card. It should be noted that the extraction restricting pin 38 can be set to be buried in the inclined portion 32 in a state where extraction is prohibited, and can protrude in response to the upstream card detection sensor 35 detecting a card in a state where extraction is prohibited, thereby preventing the extraction of the game card. It should be noted that further, even in cases where the game card is extracted excessively, the game card is sent back in the reverse direction, and the game card stays at the opening 20, etc., the extraction restricting pin 38 can still operate.

[0111] Thus, there is no need for the operation of protruding the extraction restricting pin 38 whenever the game ends and retracting the extraction restricting pin 38 whenever the game starts. This can prevent the dealer or the player from being irritated by the mechanical noise generated by the up-and-down movement of the extraction restricting pin 38, and can also reduce the possibility of malfunction caused by repeated operations.

[0112] In the above-described embodiment, the side cover 13 is configured to be rotatably movable between the covering position and the open position. However, alternatively, the side cover 13 may be configured to be movable between the covering position and the open position by translational movement. In addition, the side cover 13 may be configured to be mountable at the covering position and also detachable from the covering position.

[0113] (Second Embodiment)

[0114] Hereinafter, the electronic shoe according to the second embodiment of the present invention will be described. In the electronic shoe according to the second embodiment of the present invention, the same reference numerals are added to the structures that are the same as those of the electronic shoe according to the first embodiment, and the description will be appropriately omitted. Figure 14 is a perspective view of the electronic shoe according to the second embodiment of the present invention. Figure 14 The electronic shoe with the upper surface cover mounted is shown. The basic structure of the electronic shoe 101 in the present embodiment is the same as that of the electronic shoe 100 in the first embodiment. The electronic shoe 101 includes a storage portion 10, an opening portion 20, an extraction guide portion 30, a hammer body 40, and a main body 50.

[0115] Figure 15 is a top view of the electronic shoe according to the second embodiment of the present invention, Figure 16 is a perspective view of the electronic shoe according to the second embodiment of the present invention. Figure 15 and Figure 16 The electronic shoe with the upper surface cover removed is shown. On the bottom surface 11 of the electronic shoe 101, a hammer body stopper 111 is provided at a position about 1 / 4 of the total length of the storage portion 10 from the rear end of the storage portion 10. One hammer body stopper 111 is provided on each of the left and right sides. The left and right hammer body stoppers 111 are continuously formed from the side walls 12 and 14, respectively. The height of the hammer body stopper 111 is about 1 mm.

[0116] If the hammer body 40 is placed on the rear end side of the storage portion 10 in a state where the upper surface cover 15 is removed, since the front end of the inclined surface 42 abuts against the hammer body stopper 111, the hammer body 40 is restricted from sliding down along the inclined surface of the bottom surface 11 and can stay on the rear end side of the storage portion 10 (upper holding position). In this state, that is, in a state where the hammer body 40 does not push the game cards forward, the dealer can perform the recovery of the remaining game cards and the loading of new game cards.

[0117] In addition, on the outer side of the upper end of the side cover 13 of the storage part 10 and on the outer side of the upper end of the side wall 12, there are provided locking protrusions 16 protruding outward. The locking protrusions 16 are provided above the slide rail 17. By engaging the locking protrusion 154 of the upper surface cover 15 described later between the slide rail 17 and the locking protrusion 16, the upper surface cover 15 is mounted and fixed to the storage part 10.

[0118] The distance from the hammer body stopper 111 to the rear end of the storage part 10 is designed such that, in a state where the front end of the inclined surface 42 of the hammer body 40 is restricted from sliding down along the inclined surface of the bottom surface 11 by the hammer body stopper 111, a gap g2 large enough to insert a finger is ensured between the rear end of the upper surface of the hammer body 40 and the rear end of the storage part 10. By ensuring this gap g2, the dealer can pick up the hammer body with a finger and hold it in the upper holding position.

[0119] Figure 17 It is a perspective view of the upper surface cover of the second embodiment of the present invention. A plurality of ribs 152 are formed on the inner side surface 151 of the upper surface cover 15 in the longitudinal direction. In addition to improving the rigidity of the upper surface cover 15, the ribs 152 also function to suppress the excessive erection of the game cards stored therein due to the action of the hammer body 40 when the upper surface cover 15 is mounted on the electronic shoe 101. That is, when the upper surface cover 15 is mounted on the electronic shoe 101, the ribs 152 abut against the upper surface (the upper long side) of the game cards stored in the storage part 10 and pushed forward by the hammer body 40.

[0120] In addition, a pressing protrusion 153 is provided on the rear end side of the inner side surface 151. In the present embodiment, the pressing protrusion 153 is provided at a position close to one side in the width direction, but the pressing protrusion 153 may be provided at the center in the width direction, a plurality of pressing protrusions 153 may be provided in the width direction, or the pressing protrusion 153 may be provided across the entire width direction.

[0121] Furthermore, longitudinal walls are formed on the long sides on both sides of the upper surface cover 15, and a plurality of locking protrusions 154 are provided at the lower ends of the longitudinal walls so as to face the inside in the width direction. When the upper surface cover 15 is in a position completely covering the storage part 10 (i.e., Figure 14 the position of the upper surface cover 15 in

[0122] Figure 18 It is a perspective view showing the relationship between the upper surface cover and the hammer body of the second embodiment of the present invention. Figure 18 The positional relationship between the two when the hammer body 40 is in the upper holding position and the upper surface cover 15 is in a state of being about to be mounted in the covering position is shown. At this time, the pressing protrusion 153 abuts against the rear end portion of the upper surface 43 of the hammer body 40.

[0123] The rear end portion of the upper surface 43 of the hammer body 40 has a flange portion 431 formed to extend from the upper surface 43. The dealer can grab the hammer body 40 or lift the rear end side by hooking a fingertip on the flange portion 431.

[0124] Figure 19 It is a perspective view of an electronic shoe according to a second embodiment of the present invention. Figure 19 The figure shows a state where new game cards are loaded while the hammer 40 is held at the upper holding position. In order to load a plurality of game cards into the entire space in front of the hammer 40 held at the upper holding position, the dealer stores the game cards in the storage section 10 in a horizontal state. As a result, the upper surfaces of the plurality of game cards are located at a lower position, and do not hinder the upper surface cover 15 from being installed in the storage section 10.

[0125] Figure 20A and Figure 20B This is a diagram for explaining the function of the pressing protrusion according to the second embodiment of the present invention. Figure 20A and Figure 20B 1 shows the position and movement of the pressing protrusion 153 when the upper surface cover 15 slides from the front to the rear along the slide rail 17. When the upper surface cover 15 is located further forward than the covering position, as shown in FIG. Figure 20A As shown, the pressing protrusion 153 is located away from the upper surface 43 of the hammer body 40. When the upper surface cover 15 slides from the front and reaches the covering position, the pressing protrusion 153 presses the rear end of the upper surface 43 of the hammer body 40 downward.

[0126] The hammer 40 is supported by the pressing protrusion 153 with the rear end of the bottom surface as a fulcrum ( Figure 20B The front end of the hammer 40 is tilted upward due to the lever principle. As a result, the front end of the hammer 40 rests on the hammer stopper 111. In this state, the hammer 40 is not restricted from moving by the hammer stopper 111, but slides downward along the inclined bottom surface 11 due to its own weight. At this time, due to the weight portion 44 of the hammer 40 (refer to Figure 18 ) is located in front of the hammer body 40 (below the inclined surface 42), so the hammer body 40 passes over the hammer body stopper 111 and slides down smoothly.

[0127] It should be noted that the diameters of the two ends of the roller 41 corresponding to the hammer stopper 111 can be designed to be smaller to adapt to the thickness of the hammer stopper 111. Therefore, the roller 41 does not need to pass over the hammer stopper 111, and the roller 41 will not be blocked by the hammer stopper 111, and the hammer 40 can move smoothly.

[0128] In this way, by sliding the upper cover 15 to the covering position, the hammer 40 is released from the state of being held in the upper holding position by the hammer stopper 111, and then slides downward to push the last game card forward. That is, in response to the upper cover 15 reaching the covering position, the holding of the hammer 40 is released. As a result, a plurality of game cards stand up due to the angle of the inclined surface of the hammer 40, but the standing of the game cards is suppressed by the rib 152 of the upper cover 15 installed.

[0129] Conventionally, the upper surface cover is installed in a state where the hammer body is slid forward due to its own weight while the upper surface cover is opened, thereby causing a plurality of game cards to stand up along the inclined surface of the hammer body. In this case, the upper surface cover overcomes the force of the hammer body moving forward due to its own weight, and the upper surface of the standing plurality of game cards is pressed downward, thereby installing the upper surface cover to the storage portion. In this case, the upper surface cover is installed from the upper side to the lower side relative to the storage portion, and a fixing method such as a magnet has to be used. When the hammer body causes a plurality of game cards to stand up due to its own weight, there is a case where the upper surface cover is tilted upward.

[0130] In contrast, in the present embodiment, the upper cover 15 is mounted on the storage portion 10 by sliding. The upper cover 15 is configured so that the upper cover 15 can slide relative to the storage portion 10, thereby being secured to the storage portion 10 by the locking protrusions 16 (see FIG. Figure 16 ) is engaged with the locking protrusion 154 of the upper cover 15 and fixed to the storage portion 10, so that the upper cover 15 can be prevented from tilting up. In addition, since the movement restriction of the hammer body 40 by the hammer body stopper 111 is released by the action of sliding the upper cover 15 in this way and the hammer body 40 slides forward, the uppermost end of the plurality of game cards can be pushed forward by the hammer body 40 at the same time as the upper cover 15 is installed in the covering position or just after the upper cover 15 is installed in the covering position, and the plurality of game cards can be effectively prevented from standing up due to the weight of the hammer body 40 by the rib 152 of the upper cover 15.

[0131] Figure 21 2 is a perspective view of an electronic shoe according to a second embodiment of the present invention. Figure 21 In FIG. 1 , the hammer 40 passes over the hammer stopper 111 and pushes a plurality of game cards forward from the end. As described above, such a state is achieved by installing the upper surface cover 15. Figure 21 , a state is shown in which the hammer 40 pushes a plurality of game cards forward after the upper surface cover 15 is removed.

[0132] Figure 22This is a perspective view showing an enlarged front portion of the electronic shoe according to the second embodiment of the present invention. In Figure 22 it shows a reverse stopper 112 being exposed by removing a part of the component on the left side. At the front end of the storage portion 10, there are two left and right reverse stoppers 112 provided to cover the upper surface opening portion. The reverse stopper 112 is used to restrict the reverse movement of the game card stored at the foremost end of the storage portion 10 due to the operation of the dealer.

[0133] The reverse stopper 112 includes a base end portion 1121 that extends rearward and upward and in a direction substantially parallel to the plane direction of the stored game card, a reverse restricting portion 1122 that is continuous from the front end of the base end portion 1121 and bends downward at a substantially right angle, and a suppressing portion 1123 that is continuous from the front end of the reverse restricting portion 1122 and extends rearward along the upper surface of the stored game card.

[0134] Figure 23A and Figure 23B This is a diagram for explaining the function of the reverse stopper of the present invention. Figure 23A It shows the normal state. In Figure 23A this state, the lower ends of the respective game cards are in contact with the bottom surface 11. As Figure 23B shown, if the foremost (frontmost) game card is pushed upward with a finger, the upper end of the foremost game card rises along the base end portion 1121 of the reverse stopper 112 and abuts against the reverse restricting portion 1122. Thereby, the reverse movement of the foremost game card can be prevented.

[0135] It should be noted that, as Figure 23B shown, a slight upward movement (reverse) before the upper end of the foremost game card abuts against the reverse restricting portion 1122 is allowed, but the foremost game card cannot be moved before the second game card can be drawn out.

[0136] Figure 24A and Figure 24B This is a diagram for explaining the reverse movement in the conventional electronic shoe. In Figure 24A and Figure 24B the example, the upper surfaces of multiple game cards stored in the storage portion are covered by a flat top portion 150. In such a case, as Figure 24A shown, if the foremost game card is pushed upward with a finger, the front end of the foremost game card enters along the top portion 150 and rises into the space between the top portion 150 and the upper ends of the multiple game cards after the second one, so that the lower end portion of the second game card is exposed. Thereby, the finger can contact the second game card, and as Figure 24B shown, the second game card can be drawn out by skipping over the foremost game card.

[0137] In contrast, in the present embodiment, since the reverse movement of the foremost game card is restricted by the reverse stopper 112, the second game card cannot be contacted and drawn out, and cheating in which game cards are drawn out in an order different from the original arrangement order can be prevented.

[0138] In the second embodiment of the present invention, the following technology is disclosed.

[0139] (1) A safety electronic shoe for a casino, which is used for storing a plurality of game cards that are drawn one by one for playing games, and includes:

[0140] A storage part for storing a plurality of stacked game cards;

[0141] An opening part for exposing the foremost game card among the plurality of game cards stored in the storage part;

[0142] A drawing guide part for guiding the foremost game card to be drawn out from the opening part;

[0143] A hammer body for pushing the rearmost game card among the plurality of game cards toward the opening part; and,

[0144] An upper surface cover that can slide between a covering position for covering the upper surface of the plurality of game cards and an open position for opening the upper surface of the plurality of game cards,

[0145] The bottom surface of the storage part is inclined so as to descend toward the opening part,

[0146] The hammer body is configured to move along the bottom surface of the storage part toward the opening part in a state where the rearmost game card is pushed toward the opening part in response to the movement of the rearmost game card toward the opening part as the foremost game card is sequentially drawn out.

[0147] The bottom surface of the storage part is provided with a hammer stopper for holding the hammer body in an upper holding position by abutting against the front end of the hammer body.

[0148] By making the upper surface cover located at the covering position, the state in which the hammer body is held at the holding position is released, and the hammer body moves toward the opening part due to its own weight and pushes the rearmost game card toward the opening part.

[0149] (2) A safety electronic shoe for a casino, which is the safety electronic shoe according to (1), wherein,

[0150] The upper surface cover has a pressing protrusion on the inner side surface.

[0151] When the upper surface cover is in the covering position, the pressing protrusion presses downward on the rear end portion of the upper surface of the hammer body held in the holding position by the hammer stopper, so that, according to the lever principle, the front end of the hammer body passes over the hammer stopper, and the hammer body moves toward the opening due to its own weight and pushes the last game card toward the opening.

[0152] (3) A safety electronic boot for use in a casino, which is the safety electronic boot for use in a casino as described in (1) or (2), wherein:

[0153] The hammer body has a flange portion extending rearward from an upper surface thereof.

[0154] (4) A safety electronic boot for use in a casino, which is the safety electronic boot for use in a casino as described in any one of (1) to (3), wherein:

[0155] The hammer stopper is arranged on both sides of the bottom surface of the storage portion.

[0156] (5) A safety electronic boot for casino use, which is the safety electronic boot for casino use according to any one of (1) to (4), wherein:

[0157] The hammer stopper is provided at a position where a gap can be ensured between the rear end of the hammer and the rear end of the storage portion when the hammer is held at the holding position.

[0158] (6) A casino safety electronic boot for storing a plurality of game cards that are drawn one by one for playing a game, and comprising:

[0159] A storage portion for storing a plurality of stacked game cards;

[0160] an opening portion for exposing a leading game card among the plurality of game cards stored in the storage portion;

[0161] a drawing guide portion for guiding the frontmost game card to be drawn out from the opening; and

[0162] a hammer for pushing the last game card among the plurality of game cards toward the opening,

[0163] A reverse stopper is provided at an upper portion of the front end of the storage portion, the reverse stopper being used to restrict reverse movement of the game cards stored in the front end of the storage portion.

[0164] (7) A safety electronic boot for a casino, which is the safety electronic boot described in (6), wherein,

[0165] The reverse stopper is arranged to cover the opening part on the upper surface of the storage part.

[0166] (8) A safety electronic boot for a casino, which is the safety electronic boot described in (6) or (7), wherein,

[0167] The reverse stopper includes: a base end portion that extends rearward and upward and in a direction substantially parallel to the plane direction of the game card stored in the storage part; and a reverse restricting portion that is continuous from the front end of the base end portion and bends downward at a substantially right angle.

[0168] (Third Embodiment)

[0169] Hereinafter, the electronic boot of the third embodiment of the present invention will be described. Figures 25 to 31 They are respectively a perspective view, a top view, a right side view, a left side view, a front view, a bottom view, and a rear view of the electronic boot of the third embodiment of the present invention. In addition, Figure 32 is a perspective view of removing the upper surface cover of the electronic boot of the third embodiment of the present invention.

[0170] In the electronic boot of the third embodiment, for the structures that are the same as those of the electronic boot of the second embodiment, the same reference numerals are added and their descriptions are appropriately omitted. The basic structure of the electronic boot 102 of this embodiment is the same as that of the electronic boot 101 of the second embodiment. The electronic boot 102 includes a storage part 10, an opening part 20, a drawing guide part 3, a hammer body 40, and a main body 50.

[0171] In the electronic boot 102 of this embodiment, compared with the electronic boot 101 of the second embodiment, the corner part at the front end of the drawing guide part 30 is chamfered to form a rounded corner. Thereby, when the dealer draws the game card C from the electronic boot 102, it is easy to perform the action of turning over the game card C so that the front side faces up. That is, if the dealer draws the game card C with the index finger of the right hand while pressing the pulp of the thumb of the right hand against the corner part on the dealer's side, the thumb contacts the front side of the game card C, the index finger contacts the back side of the drawn game card C, and then the game card C can be pinched, and the subsequent action of turning over the game card C can be easily performed.

[0172] In the electronic shoe 102 of the present embodiment, magnets are respectively built in the rear end of the upper surface cover 15 and the rear end portion of the storage portion 10 that contacts the rear end of the upper surface cover 15 when the upper surface cover 15 is installed. Thus, in the state where the upper surface cover 15 is installed on the electronic shoe 102, its position is maintained by the magnetic force of the magnets. In addition, by sliding the upper surface cover 15 against the magnetic force of the magnets, the upper surface cover 15 can be easily detached.

[0173] In the electronic shoe 102 of the present embodiment, metal reinforcing plates are respectively built in the side surface cover 13 and the side wall portion that integrally forms the side surface with the side surface cover 13. Thus, when grasping the side surface cover 13 and the portion of the side wall 12 opposite to the side surface cover 13 to lift the electronic shoe 102, even when an inward pressure is applied to the side surface cover 13, the deformation of the side surface cover 13 can be reduced.

[0174] In the electronic shoe 102 of the present embodiment, a protrusion 157 extending in the front-rear direction is formed on the outer side of the side surface of the upper surface cover 15. Thus, in the state where the upper surface cover 15 is installed, it is possible to easily hook a finger on the protrusion 157 to lift the electronic shoe 102.

[0175] As Figure 31 shown, an interface 62 for connecting to an external device and a power switch 61 of the electronic shoe 102 are assembled on the back surface of the electronic shoe 102.

[0176] As Figure 32 shown, chamfers are applied to the outer side portions 132 at the front end and the upper end of the rear end of the side surface cover 13 and the portions 141 of the side wall 14 opposite to the outer side portions 132 of the side surface cover 13. Thus, during the process of the upper surface cover 15 sliding to the closed position, it is possible to prevent the inner side surface of the upper surface cover 15 from getting stuck on the step at the boundary between the upper end of the side surface cover 13 and the side wall 14 and hindering the smooth sliding.

[0177] Figure 33 FIG. is a diagram showing a display example of the result display of the third embodiment of the present invention. The result display 55 of the present embodiment displays information in two rows. Specifically, on the result display 55, as the game result, on the left side, in the upper half, the face value and suit of the two game cards C as the banker's hand are displayed, and in the lower half, the units digit of the sum of the face values of the two game cards C as the banker's hand is displayed. On the right side, in the upper half, the face value and suit of the two game cards C as the player's hand are displayed, and in the lower half, the units digit of the sum of the face values of the two game cards C as the player's hand is displayed.

[0178] In the electronic shoe 102 of the present embodiment, as the result display lamp 54, in addition to the lamps for respectively displaying the results of the player winning, the banker winning, and a tie, a lamp for displaying the banker 6 is also provided. The banker 6 means that the banker's hand wins with 6. In this case, even if a bet is placed on the banker winning, the amount of game coins paid is half of the bet amount. In addition, in the case where a betting area for betting on the banker winning with 6 (referred to as "super 6", "lucky 6", etc.) is provided in the betting area, the game coins placed here are paid at a multiple larger than 1 times (for example, 24 times).

[0179] Like this, in the case of the banker 6 appearing, the dealer must perform a payment operation different from the normal one. Therefore, in the electronic shoe 102 of the present embodiment, a lamp for indicating the appearance of the banker 6 is provided as one of the result display lamps 54.

[0180] Figure 34 It is a perspective view showing the details of the drawing guiding part of the third embodiment of the present invention. In Figure 34 it shows the internal structure of the restricting part 31 after removing the restricting part 31. The front end parts of the side walls 12 and 14 are respectively provided with restraining parts 18 for restraining the upward warping of the game cards C stored. The lower surface of the restraining part 18 has a downwardly convex curved shape. According to this structure, the front end of the foremost game card C stops in front of the restricting rod 37, and the foremost game card C stored in the storage part 10 will not be pushed onto the restricting rod 37 due to its own weight and the pressing of the hammer body 40.

[0181] With such a structure, when the restricting part 31 is removed as shown in Figure 34 and the restricting rod 37 is maintained, the game cards C will not get in the way. That is, the height of the restricting rod 37 needs to be finely adjusted to prevent two cards from being drawn. Thus, sometimes adjustment needs to be performed during the process of using the electronic shoe 102. In this case, the foremost game card C will not contact the restricting rod 37 either. Therefore, the adjustment of the restricting rod 37 can be performed without removing the game cards C from the storage part 10.

[0182] As shown in Figure 34 the electronic shoe 102 of the present embodiment is provided with a sensor cover 39 for covering the code reading sensors 33, 34 and the card detection sensors 35, 36. The sensor cover 39 is provided with packing for dust prevention treatment on the outer peripheral part so that the paper dust of the game cards C will not invade the inside. The sensor cover 39 is made of a transparent material.

[0183] In addition, on the sensor substrate, the periphery of the sensor chip is surrounded by a sponge-like dustproof material or a sealing material so that the paper dust of the game card C does not enter the code reading sensors 33 and 34 and the card detection sensors 35 and 36.

[0184] Figure 35 It is a perspective view of the restricting portion of the third embodiment of the present invention. The restricting portion 31 has a substantially fork-like shape, and a locking claw 22 is provided on the lower surface of the front end portion. The locking claw 22 is locked to the claw receiving holes 19 formed at the front end portions of the side walls 12 and 14. By the engagement of the locking claw 22 of the restricting portion 31 with the claw receiving holes 19 of the side walls 12 and 14, it is possible to prevent the front end portions of the side walls 12 and 14 from expanding outward to the left and right and to prevent the front end portion of the restricting portion 31 from tilting upward.

[0185] Figure 36 It is a perspective view of the upper surface cover of the third embodiment of the present invention. A plurality of rib portions 152 are formed on the inner side surface 151 of the upper surface cover 15. In addition, guide portions 155 extending in the length direction are formed on the inner side surface 151 at positions close to the left and right side walls 156. When the upper surface cover 15 is mounted on the electronic shoe 102, the upper ends of the side walls 12 and 14 and the side surface cover 13 are inserted into the gaps between the guide portions 155 and the left and right side walls 156.

[0186] That is, in a state where the upper surface cover 15 is mounted, the upper ends of the side walls 12 and 14 and the side surface cover 13 are fitted and fixed in the gaps between the guide portions 155 formed on the inner side surface 151 of the upper surface cover 15 and the side walls 156. Thereby, in a state where the upper surface cover 15 is mounted, the side walls 12 and 14 and the side surface cover 13 are reliably fixed to the upper surface cover 15, and in cooperation with the action of the above-described metal reinforcing plate, it is possible to reduce the deformation when lifting the electronic shoe 102.

[0187] In a card game using the electronic shoe 102, there are game operations of a type called a riffle card game in which a player is allowed to turn over a game card C drawn from the electronic shoe 102, and a game operation of a type called an open card game in which a dealer himself / herself turns over a game card C drawn from the electronic shoe 102. In the case of an open card, the dealer draws out one game card C from the electronic shoe 102, turns it over, and places it on the game table.

[0188] Figure 37 It is a perspective view of the electronic shoe of the third embodiment of the present invention. In the case of an open card as described above, bottom heightening members 71 and 72 for raising the bottom of the electronic shoe 102 are mounted on the bottom surface of the electronic shoe 102. As a result, the height of the upper surface of the drawing guide portion 30 on which the drawn game card C slides from the tabletop of the game table becomes higher, and it is easier for the dealer to pinch the drawn card.

[0189] The bottom heightening member 71 is installed at the front end portion of the bottom surface. In addition, two bottom heightening members 72 are respectively installed on the left and right of the rear end portion of the bottom surface. The bottom heightening member 71 can be installed on the bottom surface by screws, and the bottom heightening member 72 can be installed on the bottom surface by acting as a screw itself.

[0190] In the electronic boot 102 of the present embodiment, similar to the electronic boot 101 of the second embodiment, it is closed by the upper surface cover 15, so that the holding of the hammer body 40 at the upper part of the storage portion 10 is released, and the hammer body 40 slides out of the storage portion 10 and presses the rearmost end of the stored game card C forward. In this way, since the structure is such that the hammer body 40 slides down by installing the upper surface cover 15, the user cannot accurately visually confirm whether the hammer body 40 is in the state of pressing the game card C forward after sliding.

[0191] Therefore, an observation window can be provided on the upper surface cover 15. This observation window can be an observation window provided at the upper part of the upper surface cover 15 and capable of observing the hammer body 40 held at the upper end portion of the storage portion 10. Thus, when the upper surface cover 15 is installed on the electronic boot 102 and the hammer body 40 slides downward, the hammer body 40 cannot be observed from the observation window, and the user can confirm that the hammer body 40 has slid down.

[0192] A sensor for detecting whether the hammer body 40 has slid from the holding position can be used instead of the observation window. For example, a sensor composed of an LED lamp and a photodiode sensor can be provided at a position corresponding to the hammer body 40 to detect whether there is a hammer body 40 at the holding position.

[0193] A computer is built into the main body 50 of the electronic boot 102 in the present embodiment. This computer includes an arithmetic processing device, a memory, and a storage device, and as the processing portion of the electronic boot 102, it runs through the program of the present embodiment and executes the following information processing. First, the processing portion stores the information of the card face value of the drawn card and the game result as log information together with the information of its date and time in the storage device. In addition, when the processing portion detects that the upper surface cover 15 has been opened and closed, and when any error occurs, these events are also stored as log information together with the information of their date and time in the storage device.

[0194] Furthermore, analysis software for analyzing these log information can be run by the processing portion. For example, this analysis software performs statistical processing on the game results or performs statistical processing on the card face values of the drawn game cards C.

[0195] The processing unit is connected to an external computer via interface 62. Thus, the external computer can read various log information stored in the storage device by being connected to the processing unit via interface 62. Therefore, the processing unit has a security function to output log information only to trusted external computers. Specifically, the processing unit communicates with the connected external computer only when an ID and a password are set and the ID and password are input from the connected external computer.

[0196] The processing unit obtains information on the face value of the game card C drawn from the code reading sensors 33 and 34. As described above, the game card C is printed with two lines of marks M1 and M2 in UV ink, and the code reading sensors 33 and 34 obtain information on the face value by reading the marks M1 and M2. At this time, a threshold value is set for the sensors to determine whether there are marks in the marks M1 and M2.

[0197] The processing unit executes a program for teaching (training) the threshold value for determining the presence or absence of the mark for the code reading sensors 33 and 34. Conventionally, the threshold value was set by operating each of the multiple sensors. According to the electronic shoe 102 of the present embodiment, these multiple code reading sensors 33 and 34 can be trained by the processing unit and an external computer connected to the processing unit.

[0198] In this training, the game card C is assembled at the position where the mark M1 is read by the code reading sensor 33, the reading value of the code reading sensor 33 is obtained, and the threshold value of the code reading sensor 33 is set based on this. In addition, similarly, the game card C is assembled at the position where the mark M2 is read by the code reading sensor 34, the reading value of the code reading sensor 34 is obtained, and the threshold value of the code reading sensor 34 is set based on this.

[0199] It should be noted that as an alternative, in the training, the processing unit can draw out the game card C, and at the same time, obtain the change in the reading values of the code reading sensors 33 and 34 (the values of the parts with the marks M1 and M2 and the parts without the marks M1 and M2), and set the threshold value based on this reading value.

[0200] In addition, the processing unit and an external computer connected to the processing unit also train the hue of the game card C. In this training, for example, about 20 game cards C are drawn out, and between them, the code reading sensors 33 and 34 are used for reading, so that the processing unit determines the hue of the game card C to adjust the white balance.
