  Furthermore, it has a control means 52 for controlling at least the gripping device body 20 and the gripping means, and a storage means 53 for storing gripping operation start positions of the two gripping arms 9 in the maintenance mode.

  Next, the operation state of such a prize holding device 10 will be described.

  First, in the normal mode, the control means 52 controls the gripping device main body 20, the lifting device 18, the moving device 31, and the gripping means 21 as follows according to an operation input to the operation means 50 by the operator.

  It waits in a state where the left gripping arm 9a is positioned at the left end of the rail 12, the right gripping arm 9b is positioned at the right end of the rail 12, and the gripping device main body is at the home position positioned on the near side.

  When a coin insertion or game start button input is detected, the game is started, the input signal of the forward switch SW1 is waited, and when the input signal of the forward switch SW1 is detected, the gripping device body 20 is detected while the signal of the forward switch SW1 is detected. Move forward.

  Next, when the input signal of the left arm switch SW2 is detected while waiting for the input signal of the left arm switch SW2, the left grip arm 9a is moved to the right while the input signal of the left arm switch SW2 is being detected.

  As a result, the operator can stop the left gripping arm 9a that has moved rightward at the prize position intended by the operator.

  As a result, the operator can stop the right gripping arm 9b that has been moved to the left at the prize position intended by the operator.

  In this state, the lowering positions of the gripping arms 9a and 9b are determined, and the lifting device 18 lowers the gripping device main body 20.

  When the gripping arms 9a and 9b are lowered to appropriate positions, the lowering operation of the gripping device main body 20 is stopped, and the gripping arms 9a and 9b are moved from the gripping motion start position O to the gripping motion end position P as shown in FIG. Is moved by moving the distance Q up to.

  When the gripping arms 9a and 9b are pressed against the prize K by the movement of the gripping arms 9a and 9b, a force in the direction opposite to the moving direction is applied to the gripping arms 9a and 9b by the prize K.

  The reaction force of the torsion spring 23 acts on the force in the opening direction, and the gripping force is applied to the gripping arms 9a and 9b.

  Next, after this prize gripping operation, the gripping device body 20 is raised by the lifting device 18.

  Next, the gripping device main body 20 is moved onto the prize dropping port 11 by the moving device 31.

  At that position, the gripping arms 9 a and 9 b are moved in the opening direction by the stepping motor, and the prize K is dropped to the prize dropping port 11.

  Next, a case where the mode changeover switch 51 is operated to switch to the maintenance mode will be described.

  In the maintenance mode, the control unit 52 controls the storage unit 53, the gripping device main body 20, the lifting device 18, the moving device 31, and the gripping unit 21 as follows.

  First, when switching to the maintenance mode, when the coin door 40 is opened, adjustment switches as shown in FIG. 4 are stored, and among the adjustment switches in the attract mode, the test switch is pressed while pressing the service switch 45. When 46 is turned ON, the input signal is detected and switched to the maintenance mode, the gripping device main body 20 is raised and moved to the home position, and in this state, the apparatus is on standby.

  The service switch 45 and the test switch 46 constitute a mode changeover switch 51.

  After the gripping device main body 20 moves to the home position, the control means 52 detects the signals of the forward switch SW1, the left arm switch SW2, and the right arm switch SW3, and the gripping device main body 20 The grip arms 9a and 9b are moved respectively.

  Further, the asthma detected by the signal of the maintenance switch 48 provided in the switch box 44 shown in FIG. 3, the position data of the gripping arms 9 a and 9 b in the gripping device body 20, that is, the gripping operation start position O is stored in the storage unit 53. Then, the gripping device main body 20 is lowered, the gripping arms 9a and 9b are moved in the closing direction (the direction in which the gripping arms 9a and 9b are close to each other) by the distance Q, the gripping device main body 20 is lifted, and the storage means 53 Based on the position data of the gripping arms 9a and 9b stored in the above, control is performed to move the gripping arms 9a and 9b to the gripping operation start position O.

  Note that the position data of the gripping arms 9a and 9b may be stored in the storage means 53 each time the left and right gripping arms 9a and 9b move and stop during the adjustment of the gripping operation start position O.

  As described above, after the gripping operation, the gripping arms 9a and 9b return to the previous gripping operation start position O, so that the gripping motion start position O determined according to the prize is used as a reference, and the gripping force adjustment mechanism 25 is used. The adjustment of the gripping force and the adjustment of the distance Q can be repeatedly performed, and appropriate adjustments can be made for individual prizes.

  Further, the operator presses the maintenance switch 48 to lower the gripping device main body 20, gripping the gripping arms 9a and 9b, lift the gripping device main body 20, and move the gripping arms 9a and 9b to the gripping motion start position O. Since it is possible to repeatedly execute fewer steps than the normal mode of return, various adjustments are repeatedly made, such as a prize grip / lift test, grip force adjustment, distance Q adjustment, and post-adjustment test. However, the time required for adjustment can be shortened than usual.

  In particular, if only the gripping force adjustment is performed, the operator can repeatedly perform the adjustment / test without squatting.

  Next, various adjustments will be described.

  The distance Q can be adjusted with the volume 47 shown in FIG. 4 in the range of 10 mm to 300 mm, for example.

  The adjustment of the gripping force is performed by removing the pin 38 from the pin insertion hole 37 and inserting the pin 38 into the predetermined restriction hole 36 with one end of the torsion spring 23 rotated by a predetermined angle restriction body. The spring tension based on the set angle by the first restricting means 26 can be changed, and the first restricting means is made by sliding the slide member 32 along the arm piece 30 and stopping it at the predetermined scale hole 29 position. The elastic force according to the length to the support position can be changed by changing the support position on the one end 28 side from the center of the 26 torsion part.

  For example, when the second restricting means 27 changes the angle of the other end 33 side of the torsion spring 23 in the B direction, the urging force (gripping force) in the A direction on the one end 28 side increases, and on the contrary, decreases.

  Further, when the first restricting means 26 moves the support position on the one end 28 side in the C direction, the elastic force (gripping force) decreases, and conversely increases.

  Therefore, by adjusting the first restricting means 26 and the second restricting means 27, it is possible to reliably perform fine adjustment from a place where the gripping force of the grip arm 9 is large to a small place.

  When the maintenance switch 48 is pushed while the gripping device main body 20 is lowered and an input signal of the maintenance switch 48 is detected, the lowering of the gripping device main body 20 is stopped, the gripping operation is performed, and the lift is performed. May be.

  Also, when the maintenance switch 48 is pushed during the ascent and an input signal of the maintenance play switch 48 is detected, the raising of the gripping device body 20 is stopped and the left and right gripping arms 9a and 9b are returned to the gripping operation start position O. You may do it.

  Further, during the maintenance mode, the depth direction adjusting means can be adjusted so that the position of the gripping device main body 20 in the depth direction can be stopped at an arbitrary position.

  As the depth adjusting means, for example, the enter switch 49 in FIG. 4 is pushed, the forward switch SW1 in FIG. 1 is pushed to move backward, and the left arm switch SW2 is pushed to move forward. .

  At this time, the position of the gripping device body 20 in the depth direction adjusted by the depth adjusting means may be stored in the storage means 53.

  When detecting switching from the maintenance mode to the normal mode, the control means 52 returns the gripping arm 9 and the gripping device body 20 to the home position.

  The present invention is not limited to the embodiments described above, and can be modified into various forms within the scope of the gist of the present invention.

  For example, in the above-described embodiment, the case where the urging force in the closing direction is applied to the gripping arm by the torsion spring has been described. However, the present invention is not limited to this example. Can be used.
