[0036] ===Embodiment===

[0037] <<Configuration of Prize Acquisition Game Device 1>>

[0038] The configuration example of the prize acquisition game device 1 according to the present embodiment will be described using Figures 1 to 3 FIGs. Figure 1 FIG. 1 is an external view showing the configuration of the prize acquisition game device 1 according to the present embodiment. Figure 2 FIG. 2 is a block diagram showing the configuration of the prize acquisition game device 1 according to the present embodiment. Figure 3 FIG. 3 is a schematic view showing the configuration of the moving part 50 according to the present embodiment.

[0039] In the following description, each direction is defined as shown in each figure, that is, the vertical direction is defined as the "up and down direction", and "up" and "down" are defined according to gravity. In addition, the front and back directions are defined from the perspective of a player facing the prize acquisition game device 1, "front" is the front side, and "back" is the back side. In addition, the direction perpendicular to the up and down and front and back directions is defined as the "left and right direction", and "right" and "left" are defined based on observation from the player side.

[0040] The prize acquisition game device 1 of the present embodiment is used when a player plays a prize acquisition game, and is equipped with an accommodation part 10 for storing one or more prizes and a base part 80 provided below the accommodation part 10.

[0041] As Figure 1 shown, the accommodation part 10 is formed of transparent members (e.g., transparent resin, glass, etc.) on the front surface and the left and right sides, so that the player can see the prizes accommodated in the accommodation space. A switch door 11 is provided at the front part of the accommodation part 10, allowing a service provider (e.g., a store clerk, etc.) to display and replenish the prizes.

[0042] The accommodation space enclosed by the accommodation part 10 serves as a game field for the player to play the prize acquisition game.

[0043] As Figure 1 and Figure 2 shown, the accommodation part 10 in the present embodiment has an acquisition part 20 for performing an operation of acquiring a prize, a moving part 50 for moving the acquisition part 20, and a display part 60 for displaying the prize in the accommodation space.

[0044] Note that in the present embodiment, as Figure 1 shown, the acquisition part 20 is arranged corresponding to each game area where the game field is divided into left and right, and each acquisition part is configured to be able to move within each game area.

[0045] The acquisition part 20 is a prize acquisition unit that acquires the prize (the prize displayed in the display part 60) accommodated in the accommodation part 10 by opening and closing the arm. As Figure 1 shown, the acquisition part 20 in the present embodiment is configured to be able to grasp the prize with three arms and is connected to the lower end of the lifting member 52a.

[0046] The moving part 50 moves the acquisition part 20 within the game field formed by the accommodation part 10. As Figure 2 shown, the moving part 50 in the present embodiment has a horizontal moving part 51 and a vertical moving part 52.

[0047] The horizontal moving part 51 moves the acquisition part 20 horizontally (i.e., front and back and left and right) on the game field. As Figure 3As shown, the horizontal movement unit 51 in this embodiment includes a left - right movement unit 53 and a front - rear movement unit 54.

[0048] The left - right movement unit 53 moves the acquisition unit 20 left and right on the game field.

[0049] As Figure 3 shown, the left - right movement unit 53 in this embodiment includes a pair of fixed rails 53a extending in the left - right direction, a left - right movement motor 53b, an encoder (not shown), and a limit sensor (not shown).

[0050] The pair of fixed rails 53a are fixed to the upper part of the accommodation unit 10 so as to be parallel to each other in the left - right direction. The front - rear movement unit 54 is attached to the pair of fixed rails 53a so as to be able to slide in the left - right direction. By driving the left - right movement motor 53b, the front - rear movement unit 54 can move left and right along the fixed rails 53a.

[0051] The encoder detects the number of revolutions of the left - right movement motor 53b. Based on the output of this encoder, the position of the front - rear movement unit 54 in the left - right direction (in other words, the position of the acquisition unit 20 in the left - right direction) can be detected.

[0052] The limit sensor is used to detect when the front - rear movement unit 54 reaches the limit position in the left - right direction (i.e., when the acquisition unit 20 reaches the limit position in the left - right direction).

[0053] The front - rear movement unit 54 moves the acquisition unit 20 in the front - rear direction on the game field.

[0054] As Figure 3 shown, the front - rear movement unit 54 in this embodiment includes a movable rail 54a extending in the front - rear direction, a front - rear movement motor 54b, an encoder (not shown), and a limit sensor (not shown).

[0055] The vertical movement unit 52 is attached to the movable rail 54a so as to be able to slide in the front - rear direction. The vertical movement unit 52 can move in the front - rear direction along the movable rail 54a by driving the front - rear movement motor 54b.

[0056] The encoder detects the number of revolutions of the front - rear movement motor 54b. The position of the vertical movement unit 52 in the front - rear direction (i.e., the position of the acquisition unit 20 in the front - rear direction) can be detected based on the output of this encoder.

[0057] The limit sensor is used to detect when the vertical movement unit 52 reaches the limit position in the front - rear direction (i.e., when the acquisition unit 20 reaches the limit position in the front - rear direction).

[0058] The vertical movement unit 52 moves the acquisition unit 20 in the vertical direction (i.e., the up - down direction) on the game field.

[0059] As Figure 3 shown, the vertical moving part 52 in this embodiment has a lifting member 52a configured to be freely telescopic in the up and down directions, a wire winding unit (not shown), a vertical moving motor (not shown), an upper limit sensor (not shown), and a lower limit sensor (not shown).

[0060] The lifting member 52a is configured by telescopically assembling a plurality of pipes with sequentially decreasing diameters, so as to be freely slidable. The acquisition part 20 is connected to the lower end of the lifting member 52a in a state of being connected to a wire passing through the inside of the pipe.

[0061] The wire winding unit is driven by an up and down moving motor to wind the wire, so as to lift the acquisition part 20 while sequentially accommodating the lower pipes in the upper pipes, or to unwind the wire, so as to lower the acquisition part 20 while sequentially feeding out the lower pipes from the upper pipes.

[0062] The upper limit sensor detects whether the rising of the acquisition part 20 has stopped by winding the wire connected to the acquisition part 20.

[0063] The lower limit sensor detects whether the falling of the acquisition part 20 has stopped based on the change in the tension of the wire connected to the acquisition part 20.

[0064] The display part 60 is used to display the prizes in the accommodation part 10 and forms the bottom surface of the game field as Figure 1 shown. The display part 60 in this embodiment is composed of a frame and a panel (not shown).

[0065] The frame is supported within the base part 80 and is configured to be able to support a plurality of panels. The panel is configured such that the prizes can be displayed on its upper surface and can be removed from and supported relative to the frame.

[0066] In addition, the arrangement area where the panels are arranged becomes a display area where the prizes can be displayed, while the arrangement area where no panels are arranged becomes an opening area where the prizes can be delivered.

[0067] When the prizes (dropped) acquired by the acquisition part 20 and then dropped pass through the opening area of the display part 60, they are considered to have moved from the game field to the base part 80. The prizes dropped from the opening area of the display part 60 are detected by an optical sensor and then guided to the prize outlet 96 via a guiding path. The optical sensor detects whether there is a prize by using a light emitting element and a light receiving element installed on the guiding path.

[0068] The base part 80 is the base of the housing provided below the accommodation part 10 and holds the accommodation part 10 at a high position so that the player can play the game facing forward in a standing position.

[0069] As Figure 1 andFigure 2 As shown, the base 80 in this embodiment has an operation unit 90, a game fee detector 93, a prize outlet 96, a setting unit 100, a control unit 110, and a storage unit 120.

[0070] The operation unit 90 allows a player to operate the game. As Figure 1 and Figure 2 shown, the operation unit 90 in this embodiment has at least a joystick 91 and operation buttons 92.

[0071] The joystick 91 is an operation lever for the player to move the acquisition unit 20 in the horizontal direction. The operation buttons 92 are operation buttons for the player to determine the position of the acquisition unit 20 in the horizontal direction. When the player presses the operation buttons 92, the acquisition unit 20 starts to descend at the determined position.

[0072] The game fee detector 93 detects the payment of the game fee by the player. The game fee detector 93 in this embodiment has a coin slot 94, a coin detection sensor (not shown), a coin passage path (not shown), and a coin box (not shown).

[0073] In this embodiment, when the player inserts a predetermined number of coins into the coin slot 94, the prize acquisition game starts. The coins inserted through the coin slot 94 are detected by the coin detection sensor.

[0074] The coin detection sensor is, for example, an optical sensor, and detects whether there are coins inserted through the coin slot 94 by means of a light emitting part and a light receiving part attached to the coin passage. The coins passing through the coin passage path in this way are stored in the coin box.

[0075] The prize outlet 96 is provided on the front surface of the base 80 for taking out the prizes that fall when the prizes acquired by the acquisition unit 20 fall through the opening area of the display unit 60.

[0076] When the player performs a game operation or the like, or when the service provider performs a setting operation, the setting unit 100 is used. As Figure 1 and Figure 2 shown, the setting unit 100 in this embodiment has a setting operation unit 101 and a screen display 102.

[0077] The setting operation unit 101 is used to receive operation inputs. The setting operation unit 101 in this embodiment is constituted by a touch panel and receives input instructions from the operator from the pressing position of the operator.

[0078] The touch panel is laminated on top of the screen display 102. When a touch operation is performed on the screen, the pressing position (contact position) can be detected based on the change in electrostatic capacitance between the fingertip and the conductive film.

[0079] The screen display 102 displays various screens, such as a game screen and a setting screen. The screen display 102 in the present embodiment is composed of a liquid crystal display.

[0080] The control unit 110 is provided in the base 80 and is a control unit for performing various controls on the prize acquisition game device 1. As Figure 2 shown, the control unit 110 includes at least a CPU 111 and a memory 112.

[0081] The CPU 111 is an arithmetic processing device for controlling the entire game device. The memory 112 is used to secure areas for storing programs of the CPU 111, working areas, etc., and includes storage elements such as RAM.

[0082] The storage unit 120 is a unit that stores programs and data for the control unit 110 to execute game processing. In the present embodiment, memory elements such as a ROM of a read-only memory area are provided.

[0083] <<Configuration of the acquisition unit 20>>

[0084] <Acquisition unit 130 of the comparative example>

[0085] First, before describing the configuration of the acquisition unit 20 according to the present embodiment, the configuration of the conventional acquisition unit 130 will be described using Figures 4 to 6 as a comparative example. Figure 4 is a perspective view showing the configuration of the acquisition unit 130 of the comparative example. Figure 5 is a front view showing the configuration of the acquisition unit 130 of the comparative example. Figure 6 is a plan view showing the configuration of the acquisition unit 130 of the comparative example. Note that in each figure, the acquisition unit 130 with the design cover removed is shown.

[0086] As Figures 4 to 6 shown, the acquisition unit 130 of the comparative example includes a base 131 that can be connected to the lower end of the lifting member 52a, an arm 139 that performs opening and closing operations, a claw 140 attached to the tip of the arm 139, an arm connection portion 138 that removably connects the arm 139 to the base 131, and a drive unit 141 that opens and closes the arm 139.

[0087] The base 131 of the comparative example has a radially extending protrusion 132 so as to have equal angular intervals around a central axis along the vertical direction. Specifically, as Figure 6As shown, it is composed of a first protrusion 132A, a second protrusion 132B, and a third protrusion 132C in the shape of a three-pronged protrusion. The first protrusion 132A, the second protrusion 132B, and the third protrusion 132C of the three-pronged protrusion shape are offset at intervals of 120 degrees in three directions with the central axis of the base 131 as the center.

[0088] The arm 139 of the comparative example is composed of three arms: a first arm 139A, a second arm 139B, and a third arm 139C, and radially extends around the central axis of the base 131 at intervals of 120 degrees. That is, as Figure 6 shown, a first arm 139A, a second arm 139B, and a third arm 139C are provided corresponding to the first protrusion 132A, the second protrusion 132B, and the third protrusion 132C.

[0089] The arm connection part 138 of the comparative example is composed of three parts: a first arm connection part 138A, a second arm connection part 138B, and a third arm connection part 138C, and is provided for each arm. That is, as Figure 4 shown, the first arm connection part 138A connects the first arm 139A to the first protrusion 132A of the base 131. Similarly, the second arm connection part 138B connects the second arm 139B to the second protrusion 132B of the base 131, and the third arm connection part 138C connects the third arm 139C to the third protrusion 132C of the base 131.

[0090] The drive unit 141 of the comparative example is composed of three parts, a first drive unit 141A, a second drive unit 141B, and a third drive unit 141C, one for each arm. As Figures 4 to 6 shown, the first drive unit 141A, the second drive unit 141B, and the third drive unit 141C respectively correspond to the first arm 139A, the second arm 139B, and the third arm 139C, and respectively drive the opening and closing of the first arm 139A, the second arm 139B, and the third arm 139C.

[0091] As Figure 4 shown, the first drive unit 141A has an arm opening and closing motor 141Aa and a gearbox 141Ab connected to the arm opening and closing motor 141Aa. The first arm 139A performs an opening and closing operation by the power of the arm opening and closing motor 141Aa transmitted via the gearbox 141Ab. Similarly, the second drive unit 141B has an arm opening and closing motor 141Ba and a gearbox 141Bb connected to the arm opening and closing motor 141Ba, and the third drive unit 141C has an arm opening and closing motor 141Ca and a gearbox 141Cb connected to the arm opening and closing motor 141Ca.

[0092] In the case of this comparative example, as Figure 4As shown, the drive units 141 (first drive unit 141A to third drive unit 141C) of the comparative example are arranged in the acquisition unit 130 in a standing state along the vertical direction (up and down direction). Therefore, as Figure 5 shown, an increase in the vertical thickness L1 (i.e., vertical height) can cause the entire acquisition unit 130 to become larger.

[0093] In addition, in the acquisition unit 130 of the comparative example, the upper spaces of each arm connection part 138 are empty respectively. For example, when observing the first arm connection part 138A, as Figures 4 to 6 shown, the upper space 143 of the first arm connection part 138A is an empty space (shown by the shaded area in the figure). Similarly, the upper spaces of the second arm connection part 138B and the third arm connection part 138C are empty. Since a large number of such empty spaces are formed in the acquisition unit 130, there is a risk that the entire acquisition unit 130 will become larger.

[0094] <The acquisition unit 20 of the present embodiment>

[0095] will be used Figures 7 to 11 to describe a configuration example of the acquisition unit 20 according to the present embodiment. Figure 7 is a schematic diagram showing the configuration of the acquisition unit 20 according to the present embodiment. Figure 8 is a front view showing the configuration of the acquisition unit 20 according to the present embodiment. Figure 9 is a plan view showing the configuration of the acquisition unit 20 according to the present embodiment.

[0096] Figure 10 is a schematic diagram for describing the relationship between the arm 29, the arm connection part 28, and the drive unit 35 according to the present embodiment. Figure 11 is a schematic diagram showing the arm 29 in the closed position according to the present embodiment. Note that in each figure, the acquisition unit 20 with the design cover removed is shown.

[0097] As Figures 7 to 9 shown, similar to the case of the above comparative example, the acquisition unit 20 according to the present embodiment includes a base 21 connected to the lower end of the lifting member 52a, an arm 29 that performs an opening and closing operation, a claw 30 attached to the tip of the arm 29, an arm connection part 28 that removably connects the arm 29 to the base 21, and a drive unit 35 that opens and closes the arm 29.

[0098] The base 21 of the present embodiment has a protruding part 22 that extends radially so as to have equal angular intervals around the central axis along the vertical direction. Specifically, as Figure 9As shown, it consists of a first protrusion 22A, a second protrusion 22B, and a third protrusion 22C in the shape of a three-pronged protrusion. The first protrusion 22A, the second protrusion 22B, and the third protrusion 22C of the three-pronged protrusion shape are offset at intervals of 120 degrees in three directions around the central axis of the base 21.

[0099] The arm 29 of this embodiment consists of three arms: a first arm 29A, a second arm 29B, and a third arm 29C, and extends radially around the central axis of the base 21. Specifically, as Figure 9 shown, the first arm 29A, the second arm 29B, and the third arm 29C are provided corresponding to the first protrusion 22A, the second protrusion 22B, and the third protrusion 22C, respectively, and each arm 29 extends radially to have an equal angular interval (120-degree interval) around the central axis of the base 21. As Figure 7 shown, the arm 29 has a claw 30 attached to its tip, and the arm connection part 28 is connected to its base.

[0100] The arm connection part 28 of this embodiment consists of three parts: a first arm connection part 28A, a second arm connection part 28B, and a third arm connection part 28C, and is provided for each arm. That is, as Figure 7 shown, the first arm connection part 28A connects the first arm 29A to the first protrusion 22A of the base 21. Similarly, the second arm connection part 28B connects the second arm 29B to the second protrusion 22B of the base 21, and the third arm connection part 28C connects the third arm 29C to the third protrusion 22C of the base 21. Hereinafter, only the first arm connection part 28A will be specifically described, and the rest will be omitted because all the arm connection parts 28 have the same configuration.

[0101] As Figure 10 and Figure 11 shown, the first arm connection part 28A includes a protrusion 28Aa, an arm shaft 28Ab that serves as a central axis when the first arm 29A rotates, a transmission gear 28Ac that rotates integrally with the arm shaft 28Ab, a torsion spring 28Ad as an example of an elastic body, and a fastening part 28Ae.

[0102] As Figure 11 shown, the protrusion 28Aa is provided at one end of the first arm connection part 28A and abuts against the stopper 24 of the base 21 to limit the rotational operation of the first arm 29A in the closing direction.

[0103] The arm shaft 28Ab is inserted into an insertion hole (not shown) of the first arm connection part 28A and is attached to the base 21 through a through hole (not shown) of the first protrusion 22A. The transmission gear 28Ac is assembled to be integrated with the arm shaft 28Ab and transmits power to the first arm 29A by driving the driving unit 35.

[0104] The torsion spring 28Ad applies a clamping force to the arm 29, and as Figure 9 shown, the torsion spring 28Ad is attached to the arm shaft 28Ab by tightening the fastening portion 28Ae to prevent detachment. The first arm connecting portion 28A is connected to the first arm 29A via the torsion spring 28Ad.

[0105] The drive unit 35 of this embodiment is composed of three parts, the first drive unit 35A, the second drive unit 35B, and the third drive unit 35C, one for each arm. As Figures 7 to 9 shown, the first drive unit 35A, the second drive unit 35B, and the third drive unit 35C respectively correspond to the first arm 29A, the second arm 29B, and the third arm 29C, and respectively drive the opening and closing of the first arm 29A, the second arm 29B, and the third arm 29C. Hereinafter, only the first drive unit 35A will be specifically described, and the rest will be omitted because all drive units 35 have the same configuration.

[0106] As Figure 10 and Figure 11 shown, the first drive unit 35A has an arm opening / closing motor 35Aa, a gearbox 35Ab connected to the arm opening / closing motor 35Aa, an output shaft 35Ac of the gearbox 35Ab, and a transmission gear 35Ad attached to the output shaft 35Ac.

[0107] The gearbox 35Ab reduces the rotational force of the arm opening / closing motor 35Aa and outputs it. Note that the transmission gear 35Ad can be directly attached to the output shaft of the arm opening / closing motor 35Aa (not shown) without passing through the gearbox 35Ab.

[0108] When the transmission gear 35Ad is rotated by the drive of the arm opening / closing motor 35Aa via the gearbox 35Ab, the power is transmitted to the transmission gear 28Ac meshing with the transmission gear 35Ad. Therefore, the first arm 29A connected to the first arm connecting portion 28A via the torsion spring 28Ad rotates around the arm shaft 28Ab.

[0109] In the case of the acquisition unit 20 according to this embodiment, different from the case in the comparative example, when two adjacent arms 29 among the three arms 29 are regarded as a group, as Figure 7 or Figure 9 shown, in each group, the drive unit 35 for opening and closing the other arm 29 among the two arms 29 is arranged in the upper space of the arm connecting portion 28 connecting one arm 29 to the base 21. This arrangement is achieved by attaching the drive unit 35 for driving the other arm 29 to the base 21 in a manner inclined toward one arm 29. That is, as Figure 9 shown, each drive unit 35 is arranged in a trident shape around the central axis of the acquisition unit 20.

[0110] Specifically, as Figure 7 or Figure 9 shown, the second drive unit 35B corresponding to the second arm 29B is disposed in the upper space of the first arm connection portion 28A corresponding to the first arm 29A. Here, this arrangement is achieved by rotating the second drive unit 35B corresponding to the second arm 29B about the output shaft 35Bc of the second drive unit 35B and tilting the base 21 toward the first arm 29A.

[0111] Then, as Figure 7 or Figure 9 shown, the third drive unit 35C corresponding to the third arm 29C is disposed in the upper space of the second arm connection portion 28B corresponding to the second arm 29B. Here, this arrangement is achieved by rotating the third drive unit 35C corresponding to the third arm 29C about the output shaft 35Cc of the third drive unit 35C and tilting the base 21 toward the second arm 29B.

[0112] In addition, as Figure 7 or Figure 9 shown, the first drive unit 35A corresponding to the first arm 29A is disposed in the upper space of the third arm connection portion 28C corresponding to the third arm 29C. Here, this arrangement is achieved by rotating the first drive unit 35A corresponding to the first arm 29A about the output shaft 35Ac of the first drive unit 35A (see Figure 11 ) and tilting the base 21 toward the third arm 29C.

[0113] In other words, as Figure 9 shown, each drive unit (the first drive unit 35A to the third drive unit 35C) is arranged in a trident shape around the central axis of the acquisition unit 20 within the acquisition unit 20.

[0114] In this way, in the present embodiment, the drive units 35 (the first drive unit 35A to the third drive unit 35C) are arranged in a state inclined with respect to the vertical direction (up and down direction) within the acquisition unit 20. Therefore, as Figure 8 shown, the thickness L2 in the vertical direction (i.e., the height in the vertical direction) can be made thinner than the thickness L1 in the above comparative example (see Figure 5 ). In other words, since the height of the drive units 35 can be arranged to be low in the vertical direction, the entire acquisition unit 20 can be reduced by storing the drive units 35 compactly inside the main body. In addition, by making the acquisition unit 20 thinner, the amount of movement in the vertical direction within the accommodation space of the acquisition unit 20 can be increased compared to the comparative example.

[0115] In addition, in the above comparative example, the upper spaces of each arm connection portion 138 in the acquisition unit 130 are empty respectively, but in this embodiment, the upper spaces of each arm connection portion 28 in the acquisition unit 20 are effectively utilized. Therefore, by reducing the wasted space inside the main body, the drive units 35 corresponding to each arm 29 can be stored compactly inside the main body, and thus the entire acquisition unit 20 can be downsized.
