An X movement button 12 for instructing the console 11 to move in the X direction and a Y movement button 13 for instructing movement in the Y direction are arranged side by side. In addition, a coin insertion slot 14 is provided.
Although not shown in FIG. 1, a coin insertion sensor 15 that detects coin insertion is provided at the coin insertion slot 14.

  The upper part of the housing 3 is covered with a shielding plate 7 so that the inside cannot be seen from the outside, and the horizontal moving body 60 is moved back and forth and left and right (XY direction) in the space hidden by the shielding plate 15. A moving mechanism for moving is provided. An expansion pipe 65 is suspended from the horizontal moving body 60, and a gripping device 70 is suspended from the lower end of the expansion pipe 65.

The moving mechanism of the horizontal moving body 60 will be described with reference to FIGS.
A pair of front and rear fixed rails 21 and 22 oriented in the left and right horizontal direction (X direction) are installed at the same height, and a moving rail 41 oriented in the front and rear horizontal direction (Y direction) is provided between the fixed rails 21 and 22. It is suspended so as to be movable in parallel in the X direction.

As shown in FIG. 5, the front fixed rail 21 has a substantially rectangular C cross section and is open at the bottom to form horizontal flange portions 21a and 21a on both sides of the opening. Projections 21b, 21b projecting upward are provided, and a projection 21c is formed at the center between the projections 21b, 21b.
At both ends of the protrusion 21c oriented in the center Y direction, a rectangular hole oriented in the Y direction and a groove extending to the rectangular hole are formed by a pair of front and rear flange portions 21d, 21d.

In the fixed rail 21, the front and rear, left and right wheels 24 are placed on the horizontal flange portions 21a and 21a, and the moving body 23 is supported so as to be movable.
The movable body 23 is formed by bending a rectangular plate into a U-shape and bending the lower portions of both side portions 23b and 23b outward with the central portion 23a facing upward to form flange portions 23c and 23c. Projecting outwardly from 23b, two wheels 24 are rotatably supported side by side on the left and right sides.

  In the moving body 23, the main body portion is inserted into the fixed rail 21 with the flange portions 23c and 23c exposed downward from the lower opening of the fixed rail 21, and the wheels 24 on both sides rest on the horizontal flange portions 21a and 21a. It is supported so as to be movable in the X direction.

  A long screw rod 25 pivotally supported at both ends is installed in the fixed rail 21 in the left-right longitudinal direction, and the screw rod 25 is threaded through a nut 26 provided integrally with the moving body 23. doing.

One end of the screw rod 25 passes through the bearing and is fitted with a gear 25a. The gear 27a is fitted on the drive shaft of the X movement motor 27 fixed to the upper surface of the end of the fixed rail 21 and the gear 25a. And the drive of the X movement motor 27 rotates the screw rod 25 through the meshing of the gear (see FIG. 4).
The rotation of the screw rod 25 moves the nut 26 screwed together with the moving body 23 in the X direction.

In this way, the upper surface of the front end of the moving rail 41 is fixed to the flanges 23c, 23c exposed below the moving body 23 moving in the X direction.
The moving rail 41 has a roller 40 projecting from the rear end thereof, and is supported by the rear fixed rail 22 through the roller 40 so as to be movable.
Therefore, the moving rail 41 is guided by the fixed rails 21 and 22 by the drive of the X moving motor 27 and is translated in the left and right X directions.

Near the left and right ends of the front fixed rail 21, brackets 30, 30 protrude rearward, respectively, and optical sensors 31, 31 are attached to the brackets 30, 30 (see FIG. 3).
As shown in FIG. 5, the bracket 30 is formed by bending a long rectangular plate so that the base end portion 30a abuts on the upper surface of the fixed rail 21, and the vertical portion 30b bent downward extends along the side surface of the fixed rail 21 to The lower end of the portion 30b is bent so that the horizontal tip portion 30c protrudes rearward, and the optical sensor 31 is fixed to the lower surface of the horizontal tip portion 30c.

  The base end portion 30a of the bracket 30 abuts on the flange portions 21d and 21d of the protrusion 21c, and penetrates the bracket 30 and the groove into the receiving plate 32 inserted into the rectangular hole below the flange portions 21d and 21d. The two left and right bolts 33 are screwed together.

  Therefore, when the bolt 33 is tightened, the head portion of the bolt 33 and the receiving plate 32 can sandwich the flange portions 21d and 21d and the base end portion 30a of the bracket 30 to fix the bracket 30, and when the bolt 33 is loosened. The bracket 30 together with the bolt 33 and the receiving plate 32 can be displaced in the left-right X direction along the groove.

In this way, the optical sensor 31 attached to the bracket 30 that can be displaced in the X direction is provided with the light projector and the light receiver facing each other in the front-rear direction, and it can be determined whether or not there is an actuator between them.
Then, a plate-like actuator 34 is projected at a predetermined position on the upper surface of the moving rail 41 that moves in parallel, and the actuator 34 that moves together with the moving rail 41 is a projector of the photosensor 31 provided at both ends of the fixed rail 21. This can be detected when it reaches between the light receivers.

When the actuator 34 detects the optical sensor 31, the movement limit of the moving rail 41 is controlled to stop the movement.
As described above, since the left and right photosensors 31, 31 can be easily displaced in the X direction, the movement limit in the X direction can be easily changed.

  The moving rail 41 oriented in the front-rear horizontal direction (Y direction) is provided with the same moving mechanism as the fixed rail 21. As shown in FIG. 6, the shape of the moving rail 41 is the same as that of the fixed rail 21, and the section is rectangular. A moving body 43 that is C-shaped and is inserted therein is movably supported via a wheel 44, and a screw rod 45 is threaded through a nut 46 that is provided integrally with the moving body 43.

The screw rod 45 is rotated by the motor 47 fixed to the upper surface of the rear end portion of the moving rail through the meshing of the gear in the same manner as the drive mechanism.
Thus, the upper surface of the horizontal moving body 60 is fixed to the flange portions 43c and 43c exposed below the moving body 43 that moves in the front-rear direction.

  As in the case of the fixed rail 21, brackets 50, 50 are projected to the left in the vicinity of both front and rear ends of the moving rail 41, and optical sensors 51, 51 are attached to the brackets 50, 50. (See FIG. 3).

  The mounting method of the bracket 50 to the moving rail 41 is the same as described above, and the base end portion of the bracket 50 is brought into contact with the flange portions 41d and 41d of the ridge 41c and inserted into the rectangular holes under the flange portions 41d and 41d. The front and rear bolts 53 penetrating the bracket 50 and the groove are screwed to the receiving plate 52 (see FIG. 6).

Therefore, when the bolt 53 is tightened, the bolt 53 and the receiving plate 52 can sandwich the flange portions 41d and 41d and the base end portion of the bracket 50 to fix the bracket 50. When the bolt 53 is loosened, The optical sensor 51 can be moved by easily displacing the bracket 50 together with the receiving plate 52 in the front-rear direction along the groove.
Therefore, the movement limit of the horizontal moving body 60 in the front-rear Y direction can be easily changed.

The horizontal moving body 60 is a rectangular casing, and an extendable pipe 68 extends vertically downward from the bottom wall.
As shown in FIG. 7, the telescopic pipe 68 has five pipes P ₁ , P ₂ , P ₃ , P ₄ , and P ₅ whose diameters are sequentially reduced from the top and are slidably connected to each other so as to be telescopic. It is configured.

  In the housing 60a of the horizontal moving body 60, a mechanism for taking in and out the wire 63 that moves up and down in the telescopic pipe 68 is built in, and the wire 63 is attached to the rotating drum 62 rotated by the Z moving motor 61 as shown in FIG. A free roller 65 is pivotally supported at the tip of a swing arm 64 that swings about the rotation shaft of the rotary drum 62.

  The swing arm 64 is urged counterclockwise in FIG. 6 by a spring (not shown), and the wire 63 fed out from the rotary drum 62 is wound around the free roller 65 and then extended downward to form the housing 60a. The inside of the telescopic pipe 68 extends downward through an opening 60b formed in the bottom wall.

A micro switch 66 is disposed below the swing arm 64 so that the swing of the swing arm 64 can be detected.
Further are arranged microswitch 67 is under the microswitch 66, the microswitch 67 is the upper end of the pipe P ₅ lowermost which has risen in the telescopic pipe 68 protruding the opening 60b of the bottom wall of the housing 60a Time can be detected.

Pipe P ₁ uppermost telescopic pipe 68 is secured to the bottom wall of the horizontal moving body 60 (see FIG. 6), the pipe P ₅ of the lowest stage is fitted to the lower end to the upper attaching member 71 of the gripping device 70 A locking tool 63a at the lower end of the wire 63 suspended in the telescopic pipe 68 is fitted to the upper mounting member 71 (see FIGS. 7 and 8).

  Therefore, the gripping device 70 is suspended from a wire 63 that hangs down from the horizontal moving body 60, and the swinging of the gripping device 70 is prevented by the five-stage telescopic pipe 68 that covers the periphery of the wire-63. The gripping device 70 is always located directly under the head.

  When the Z movement motor 61 is driven to rotate the rotary drum 62 and wind the wire 63, the gripping device 70 rises. As the gripping device 70 rises, the telescopic pipe 68 is changed from the lower pipe to the upper pipe one by one. When the rotary drum 62 is reversely rotated to unwind the wire 63, the gripping device 70 is lowered by its own weight, and the telescopic pipe 68 is extended.

And when in the state in which the wire 63 is hung lowermost pipe P ₅ and gripping device 70, the wire 63 is subjected to any tension in the Z direction is pulled downwardly, thus the swinging arm 64 downward It swings and the contact of the micro switch 66 is turned on. However, when the gripping device 70 descends and touches the prize 8 or reaches the bottom wall of the housing 3, the wire 63 is loosened and is attached by a spring. The biased swing arm 64 swings upward as indicated by a two-dot chain line in FIG. 6 to turn off the contact of the micro switch 66, and detects that the gripping device 70 has come into contact with the prize 8 or the bottom wall. can do.

Even when the telescopic pipe 65 is extended to the longest, the wire 63 is loosened. Similarly, it can be detected that the contact of the micro switch 66 is turned off and the lowering of the gripping device 70 has reached the limit.
The lowering limit height of the gripping device 70 is lower than the bottom wall of the housing 3 and reaches the lowering limit when the gripping device 70 is inserted into the prize throwing cylinder 9 (see FIG. 12).

Further, when the rotating drum 62 to reduce the telescopic pipe 68 is incorporated sequentially placed five pipes winding wire 63, the microswitch upper end of the lowermost pipe P ₅ is projecting the opening 60b of the bottom wall of the housing 60a 67 can detect this and detect that the upper limit of the gripping device 70 has been reached.

In the present prize acquisition game device 1, since the expansion pipe 65 has five stages, which is larger than the conventional one, the vertical movement distance of the gripping device 70 can be increased, and the rising position of the gripping device 70 when it is most contracted can be further increased. It can be set to a high position.
Furthermore, the uppermost position of the gripping device 70 can be further increased by providing six or more expansion pipes.

  As shown in FIGS. 8 and 9, in the gripping device 70, the support frame 72 that erects the upper mounting member 71 supports the arm opening / closing motor 73 at the center, and is protruded from the support frame 72 to the left and right. The base ends 75a and 75a of the gripping arms 75 and 75 are pivotally supported on the brackets 72a and 72a via the support shafts 74 and 74, respectively.

The left and right gripping arms 75 and 75 are symmetrical, bend at a substantially right angle at the center and extend downward, and gripping claws 76 and 76 project from the tip portions thereof.
Rollers 77 and 77 are pivotally supported on the base end portions 75a and 75a of the gripping arms 75 and 75, and a pair of front and rear springs are provided between the projections below the base end portions 75a and 75a. 78 is interposed to bias both gripping arms 75 and 75 toward each other.

An oblong disc-shaped rotary cam 79 is fixed to the drive shaft protruding downward of the arm opening / closing motor 73 supported by the support frame 72 in the horizontal position, and the rotation cam 79 has the above-mentioned periphery on the periphery. The left and right rollers 77 and 77 of the base end portions 75a and 75a of the gripping arms 75 and 75 are in contact with each other.
Therefore, the left and right gripping arms 75 and 75 are biased in the closing direction by the spring 78 and sandwich the rotating cam 79 via the rollers 77 and 77.

  When the oval rotating cam 79 is at a rotation angle such that the left and right widths are long as shown by the solid line in FIG. 8 and the broken line in FIG. 9, the gripping arms 75 and 75 are in the fully open state. Yes, when the rotary cam 79 is rotated by driving the arm opening / closing motor 73, the left and right widths of the rotary cam 79 are gradually shortened, and the gripping arms 75, 75 are closed by the urging force of the spring 78. When rotated 90 degrees, the horizontal width becomes the shortest as shown by the two-dot chain line in FIGS. 8 and 9, and the gripping arms 75, 75 are completely closed.

By the closing operation of the left and right grip arms 75, 75, the prize 8 can be sandwiched and gripped.
The present prize acquisition game apparatus 1 is intended for a larger prize than before, and accordingly, the opening width of the holding arms 75, 75 is increased so that the larger prize can be sandwiched. A large gripping arm is used.

The base end portions 75a and 75a of the support frame and the gripping arms 75 and 75 are covered with the united case 80 divided in the first and second half.
The drive mechanism of the gripping device 70 of the present prize acquisition game apparatus 1 has the above-described structure, and is driven and controlled by a computer. A schematic block diagram of the control system is shown in FIG.

The CPU 85 uses the RAM 87 as appropriate according to the program written in the ROM 86 to perform control processing and advance the game.
Various instruction signals and detection signals are input to the CPU 85 via the input interface 88.
Operation signals and the like from the coin insertion sensor 15, the X movement button 12, and the Y movement button 13 are input.

  Of the optical sensors 31 and 31 that detect the limit of movement of the horizontal moving body 60 and the gripping device 70 in the X direction, the optical sensor 31 on the left side in the X direction is an X home position switch that detects the home position of the gripping device 70. The right optical sensor 31 corresponds to an X limit switch that detects the movement limit of the gripping device 70 in the X direction, and also detects the limit of movement of the horizontal moving body 60 and the gripping device 70 in the Y direction. Of the optical sensors 51, 51, the front optical sensor 31 in the Y direction corresponds to a Y home position switch that detects the home position of the gripping device 70, and the rear optical sensor 51 moves the horizontal moving body 60 in the Y direction. This corresponds to a Y limit switch that detects the limit.

  Detection signals from the X home position switch (light sensor) 31, Y home position switch (light sensor) 51, X limit switch (light sensor) 31, and Y limit switch (light sensor) 51 are sent to the CPU 85 via the input interface 88. Is input.

  Further, the micro switch 66 corresponds to a Z tension switch for detecting the Z downward tension of the wire 63, and the micro switch 67 corresponds to a Z limit switch for detecting the upper limit of the gripping device 70 in the Z direction. Detection signals from the micro switch 66 and the Z limit switch 67 are also input to the CPU 85.

  The CPU 85 that has input the above various signals processes the drive instruction signal and outputs the drive instruction signal to the X movement motor 27, Y movement motor 47, Z movement motor 61, and arm opening / closing motor 73 via the output interface 89. Drive control.

The control procedure by the above control system will be described below based on the flowchart of FIG.
Immediately before the start of the game, the gripping device 70 is located at the highest position where the telescopic pipe 65 is contracted in the home position above the premium throwing cylinder 9 in the left front of the housing 3 and the gripping arm. 75 and 75 are in a closed state, and the prize acquisition game device 1 is in an advertising state by lighting or sound (step 1).

  When the player inserts a coin into the coin insertion slot 14 of the console 11, the coin insertion sensor 15 detects the insertion of the coin (step 2), and proceeds to step 3 to start the game.

  When the X movement button 12 is pressed (step 3), the process proceeds to step 4 where the X movement motor 27 is driven and the gripping device 70 at the home position moves to the right in the X direction to detect the X direction movement limit. Until the switch 31 is turned on (step 6), the steps 4, 5 and 6 are repeated to continue the rightward movement of the X, and the gripping device 70 has reached the required position until the X limit switch 31 is turned on. When the X movement button 12 is released sometimes, the process jumps from step 5 to step 7 and the gripping device 70 stops at the same position.

  If the gripping device 70 reaches the limit in the X direction and the X limit switch 31 is turned on while the X movement button 12 is being pressed, the process proceeds from step 6 to step 7 and the gripping device 70 stops at the limit position.

  Next, when the Y movement button 13 is pressed (step 8), the Y movement motor 47 is driven and the gripping device 70 moves rearward (back side) Y (step 9), and the Y limit switch 51 is turned on (step 11). ), When the operation button 13 is released when the desired gift is reached, the process proceeds from step 10 to step 12 and the gripping device 70 stops at the same position.

  If the gripping device 70 reaches the limit in the Y direction and the Y limit switch 51 is turned on while the Y movement button 13 is being pressed, the process proceeds from step 11 to step 12, and the gripping device 70 stops at the limit position.

Thereafter, in step 13, the arm opening / closing motor 73 is driven to rotate the rotary cam 79 by 90 degrees to open the gripping arms 75, 75, and then the gripping device 70 is lowered by driving the Z movement motor 61 (step 14).
When the lowered gripping device 70 comes into contact with the prize 8 or the bottom wall (see the two-dot chain line in FIG. 12), the wire 63 is loosened and the Z tension switch 66 is actuated to proceed from step 15 to step 16, and the arm opening / closing motor 73 Is driven to close the gripping arms 75 and 75 to grab the prize 8.

  Regardless of whether the gripping is successful or unsuccessful, the gripping device 70 is lifted (step 17). When the gripping device 70 is lifted to the upper limit and the Z limit switch 61 is activated (step 18), the lifting is stopped and the process proceeds to step 19.

  In step 19, the gripping device 70 is moved in the X left home position direction by driving the X movement motor 27, and in step 20, the gripping device 70 is moved in the Y forward home position direction by driving the Y movement motor 47. Steps 19, 20, 21, and 22 are performed until the X home position switch 31 is actuated (step 21) and the Y home position switch 51 is actuated (step 22), that is, until the gripping device 70 returns to the home position. The movement of the gripping device 70 in the XY direction is continued repeatedly.

  When the Y home position switch 51 is activated, the process proceeds from step 22 to step 23, the movement in the Y direction is stopped, and only the movement of the gripping device 70 toward the X direction home position is continued (steps 23, 24). When the position switch 31 is operated, the process proceeds from step 24 to step 26, the movement in the X direction is also stopped, and the gripping device 70 is stopped at the home position.

  If steps 19, 20, 21, and 22 are repeated to move the gripping device 70 in the XY direction and the X home position switch 31 is activated first, the process proceeds from step 21 to step 25, The movement stops and only the movement of the gripping device 70 toward the Y-direction home position continues (steps 20, 21, 25). When the Y-home position switch 51 is activated, the process proceeds from step 25 to step 26 to move in the Y direction. The gripping device 70 stops at the home position.

When the gripping device 70 returns to the home position in this manner, the Z movement motor 61 is driven in step 26 to lower the gripping device 70.
Since the gripping device 70 is located directly above the prize throwing cylinder 9, when it is lowered as it is, it enters into the prize throwing cylinder 9, the expansion pipe 65 extends to the longest, and the gripping device 70 reaches the lowering limit. The tension switch 66 is lowered until it operates (steps 26 and 27).

  When the Z tension switch 66 is actuated (step 27) and the gripping device 70 reaches the lowering limit, the gripping device 70 is lowered until it almost enters the prize throwing cylinder 9 as shown by the solid line in FIG. Then, the process proceeds to step 28, where the arm opening / closing motor 73 is driven to open the gripping arms 75, 75. If the gripping arms 75, 75 are holding the prize 8, the prize 8 is dropped to the prize receiver. Then, the player can open the prize take-out lid 10 and take out the prize 8 from the prize receiver.

  Thereafter, the gripping device 70 is raised (step 29). When the upper limit is reached and the Z limit switch 67 is actuated (step 30), the operation proceeds to step 31 to drive the arm opening / closing motor 73 to close the gripping arms 75, 75. Then, the process returns to step 1 to finish one game.

Unlike the prior art, the gripping device 70 descends into the prize throwing cylinder 9 and then opens the prize 8 and drops it to the prize receptacle, so that the prize 8 falls from a low height and the impact of the fall on the prize 8 is small. Even if a precision machine or a fragile object is used as a prize, there is no possibility of damaging the prize.
Therefore, there are many types of articles that can be handled as prizes, and the versatility for the types of prizes is high.

As described above, the present prize acquisition game device 1 has a large prize placed in the housing 3 for a large prize 8 than the conventional one, and a grip arm 75 for gripping the large prize 8. 75 is using a big one.
Therefore, as shown in FIG. 2, the range in which the gripping device 70 can move so as not to interfere with the side wall of the housing 3 is the gripping device 70 ′ having a small gripping arm 75 ′ shown by a two-dot chain line in FIG. Narrower than the case.

  Therefore, the positions of the optical sensors 31 and 31 for determining the movement limit in the right and left X direction of the holding device 70 and the positions of the optical sensors 51 and 51 for determining the movement limit in the front and rear Y direction are set to the large holding arms 75 and 75. It is fixed at the required position.

  In the case where the size of the prize 8 is small as in the prior art, the gripping arm may be replaced with a small one and the mounting positions of the optical sensors 31, 31, 51, 51 may be changed.

  For example, in order to displace the optical sensor 31, the bolts 33 that fix the bracket 30 supporting the optical sensor 31 to the fixed rail 21 are loosened, and the flange portions 21d and 21d and the proximal end portion 30a of the bracket 30 are sandwiched. The light sensor 31 is moved to the required position by loosening the space between the receiving plate 32 and displacing the bracket 33 together with the bolt 33 and the receiving plate 32 in the right and left X direction along the groove and tightening the bolt 33 again. It is fixed with.

The left and right photosensors 31, 31 on the fixed rail 21 can be displaced outward as the prize size decreases, and the range of movement of the gripping device 70 can be expanded.
The moving range in the front-rear direction of the gripping device 70 can also be enlarged or reduced by displacing the front-rear optical sensors 51, 51 in the moving rail 41 in the front-rear Y direction by the same operation.

  In this way, the present prize acquisition game apparatus 1 can cope with a change in the prize size by a simple operation without exchanging the entire mechanism for moving the gripping device 70, and is excellent in versatility with respect to the prize size. Yes.

  In addition, the present prize acquisition game apparatus 1 is connected to a 5-stage pipe, which has a larger number of stretchable pipes 68 than the conventional one, to prevent swinging of the wire 63 suspending the gripping apparatus 70 and maintain linearity, so that the ascending / descending distance is large. Since the highest position is high, it is possible to deal with small to large prizes.

  In addition, by extending and extending the telescopic pipe horizontally, even in the case of a prize acquisition game device whose tip pierces the prize, it is possible to increase the moving distance of the distal end by increasing the number of stages of the telescopic pipe, resulting in a large prize Can also cope with.

  In the above embodiment, for example, the optical sensors 31 and 31 that determine the movement limit in the left-right direction of the gripping device 70 are separately displaced. However, both the optical sensors 31 and 31 approach or separate from each other by the same distance. As shown in FIG. 13, the racks 91 and 92 that extend in parallel to face the central pinion 90 are engaged with each other, and brackets 93 and 94 are projected from the racks 91 and 92, respectively. The optical sensors 95 and 96 may be provided at predetermined positions of the brackets 93 and 94, that is, on a locus along which the actuator 97 moves.

When the pinion 90 rotates at the center fixed position, the racks 91 and 92 move in opposite directions so that the optical sensors 95 and 96 supported by the brackets 93 and 94 can be simultaneously moved closer and away from each other. Work becomes easy.
The pinion 90 can be locked at an arbitrary angle.

  As another embodiment, as shown in FIG. 14, a belt 103 is hung between the left and right pulleys 101 and 102 via a guide roller 104, and brackets 105 and 106 are fixed to predetermined positions on the left and right sides of the belt 103. The optical sensors 107 and 108 are provided at predetermined positions of the brackets 105 and 106, that is, on the locus on which the actuator 109 moves.

When the pulley 103 and 102 are rotated to rotate the crossed belt 103, the brackets 105 and 106 move in the opposite directions together with the optical sensors 107 and 108, and the optical sensors 107 and 108 simultaneously approach or separate from each other. And can be displaced.
Therefore, the work accompanying the change of the prize size is easy.

In the above embodiment, the optical sensor is disposed on the side of the rail or the like that guides the moving object, and the actuator that operates the optical sensor is provided on the side of the moving object. An actuator may be arranged on the side, and a light sensor may be provided on the side of the moving object.
By doing so, the movement limit in the position direction can be detected by one optical sensor.

Moreover, although the optical sensor was used to detect the movement limit, other limit switches, magnetic sensors, etc. can also be used.
Furthermore, in the above-described embodiment, the horizontal movement of the gripping device is the movement in the left-right direction and the front-rear direction, that is, the movement in the X direction and the Y direction corresponding to the XY coordinates. It is also possible to displace the sensor for detecting the movement limit even in the prize acquisition game device configured to move and move in the radial direction from the origin.

Further, there is an example in which the moving body moves in the vertical Z direction. For example, in the embodiment shown in FIG. 15, a plurality of rotating discs 120 rotating in the center are provided in the radial horizontal direction, and the outer periphery has four vertical positions. A vertically moving body 122 that moves up and down along a guide rail 121 oriented in the direction is disposed.
A prize pushing member 123 is provided on the up-and-down moving body 122 so as to be stretchable toward the center.

  A prize is placed on each turntable 120 and rotated, and the player operates the up-and-down moving body 122 to raise it to the height of the aimed prize, and the prize pushing member 123 is projected at an optimal timing to give the prize. Play to plunge.

In such a game apparatus, a sensor for detecting the upper and lower movement limits of the vertical moving body 122 is provided, and the sensor is also attached so as to be vertically movable.
Therefore, the position of the sensor can be easily displaced according to the size of the prize, and versatility with respect to the prize size can be enhanced.

Next, still another embodiment will be described with reference to FIG.
The prize game acquisition apparatus according to the present embodiment is a game apparatus having the same structure as the prize acquisition game apparatus 1 shown in FIGS. 1 to 12, and the control system is the same as that shown in the block diagram of FIG. There is only a difference in the method of moving the gripping means to the home position.

Therefore, the control procedure will be described below based on the flowchart shown in FIG.
The process from the advertisement state in Step 1 to the determination of whether or not the Z limit switch 61 is activated in Step 68 is exactly the same as Step 1 to Step 18 in the flowchart of FIG.

  When the gripping device 70 descends and tries to grip the prize 8, the gripping device 70 rises regardless of whether the gripping is successful or unsuccessful (step 67), rises to the upper limit, and the Z limit switch 61 is activated. (Step 68), the ascent is stopped and the routine proceeds to Step 69.

  In step 69, the gripping device 70 is first moved in the X left home position direction by driving the X movement motor 27. In the next step 70, it is determined whether or not the X home position switch 31 is operated, and there is no operation. In the meantime, the process returns to step 69 and continues to move to the left in the X direction.

  Similarly, in step 71, the gripping device 70 is moved in the Y front home position direction by driving the Y movement motor 47, and the gripping device 70 is moved to the home position until the Y home position switch 51 is actuated (step 72). The movement is continued until it returns to step 73, and the process proceeds to step 73.

  As described above, after the gripping device 70 grips the prize 8, it moves to the home position where the prize throwing cylinder 9 is located. First, the gripping apparatus 70 moves to the left in the X direction and then moves forward in the Y direction to the home position. It is controlled to reach.

  Therefore, it is avoided that the gripping device 70 that has succeeded in gripping the prize 8 reaches the home position, and the prize 8 is prevented from coming into contact with the front wall, and approaches the front wall (player side wall) of the transparent plate 6 of the housing 3. Thus, it is possible to prevent the prize 8 gripped and moved so as to come into contact and rub, or to drop the prize 8 gripped by the contact or rubbing.

  Since the housing 3 grips the left and right side walls of the transparent plate 6 with the gripping arm 75 sandwiching the prize 8 from the left and right, the prize 8 gripped even when the gripping arm 75 is closest to the left and right side walls. There is no contact with the left and right side walls, and the rear wall of the transparent plate 6 is located far behind the movement range of the gripping device 70, so that the gripped prize 8 does not touch.

  Therefore, there is a risk of contact with the prize 8 in which only the front wall of the transparent plate 6 is gripped. However, as described above, by moving the X in the left direction first, the prize 8 is prevented from coming into contact with the front wall. Thus, the above-described problems can be prevented.

In particular, when handling a larger prize 8 than before, there is a high possibility that the prize 8 will come into contact with the transparent plate 6 of the housing 3. Even in such a case, the return route to the home position is as described above. Can solve such problems.
Steps 73 to 78 are the same as steps 26 to 31 in the flowchart of FIG.

  As another method for controlling the movement of the gripping device 70 to the home position, as long as the prize 8 gripped by the front wall of the transparent plate 6 is in a range where it does not come into contact, the movement in the X left direction and the Y forward direction is performed simultaneously. And then only move in the X left direction first, then move in the Y forward direction, or if the X left direction and the Y forward movement are performed simultaneously and the X left limit is reached, After that, the home position is reached only by moving forward in the Y direction.

  Thus, by moving the X left direction and the Y front direction at the same time halfway, the return time to the home position can be shortened without bringing the gripped prize 8 into contact with the front wall.
