JP 2003-27532 A

  The problem to be solved by the invention is that the setting hole is illegally changed because the keyhole of the setting lock exists in the OFF operation position and the movable piece is separated from the switch button.

  In the slot machine setting change device according to the present invention, a setting lock, a lock switch, a setting operation unit, a setting switch, and a control device are installed in the mechanism housing, and the setting lock is operated by a human by an off operation position and an on operation. The lock switch is provided with a switch button on the switch body, and when the movable piece rotates from the on operation position to the off operation position, the lock switch outputs an off signal to the control device. When turning from the OFF operation position to the ON operation position, the lock switch outputs an ON signal to the control device. When the setting operation unit is operated by a person, the setting switch outputs an installation signal to the control device, and the control device locks. The setting change process is canceled by the OFF signal input from the switch, the control device permits the setting change process by the ON signal input from the lock switch, and the control device performs the setting change process. In a setting change device for a slot machine that changes and sets the probability of winning in a winning lottery process when an installation signal is input from the setting switch in the enabled state, the movable piece moves from the on operation position to the off operation position. As the switch rotates, the switch button of the lock switch is pushed in the direction of the switch body so as to contact or approach the switch body, and as the movable piece rotates from the off operation position to the on operation position, the switch of the lock switch The main feature is that the movable piece and the lock switch are installed inside the mechanism housing so as to release the push of the button in the direction of the switch body and leave the switch body. In the setting change device of the slot machine according to the present invention, the lock switch may be connected to the input port of the control device in a normally open form.

  In the slot machine setting changing device according to the present invention, when the movable piece of the set lock exists in the OFF operation position, the movable piece contacts or contacts the switch body by pushing the switch button of the lock switch in the direction of the switch body. Since the unauthorized operation member cannot enter between the movable piece and the switch button, even if the setting operation unit is pressed with the unauthorized operation member and the setting switch outputs the setting signal to the control device, Since the ON signal from the lock switch is not input and the control device does not set the permission for the setting change processing, the control device performs the setting change processing even if the setting operation unit is pushed by the unauthorized operation member. Since it is not executed, it is possible to prevent an illegal act of a player who sets the probability of winning by lottery by changing it illegally, and the movable piece of the setting lock is turned on from the off operation position. Since the set lock must be operated with a key in order to be present at the work position, even if the movable piece is separated from the switch button, the player's fraud is set by changing the probability of winning by the lottery. There is an advantage that an action can be prevented. In the setting change device of the slot machine according to the present invention, if the lock switch is connected to the input port of the control device in a normally open form, the logic circuit for the input port of the control device can be used as is, Even if the normally open contact and normally closed contact of the lock switch are improperly shorted while the movable piece of the set lock is in the OFF operation position, the control device does not set the permission for the setting change process. Therefore, it is possible to prevent an illegal act of a player who illegally changes and sets the probability of winning by lottery.

  1 to 3 show the best mode for carrying out the invention. FIG. 1 schematically shows a setting change device of a slot machine. FIG. 2 is an exploded view of the power supply device 122 provided with the setting lock 1, the lock switch 2, the setting operation unit 3, and the setting switch 4 of the setting change device. FIG. 3 shows the appearance of the assembled power supply device 122.

  In FIG. 1 a, when the keyhole 8 of the inner cylinder 7 in the set lock 1 exists at the off operation position 11 displayed on the front surface of the outer cylinder 6, the movable piece 10 provided on the inner cylinder shaft 9 is a lock switch. When the switch button 15 of No. 2 is pressed and the keyhole 8 exists at the ON operation position 12 displayed on the front surface of the outer cylinder 6, the inner part of the inner cylinder 7 is arranged so that the movable piece 10 is separated from the switch button 15 of the lock switch 2. The cylinder shaft 9 and the movable piece 10 are connected so as to rotate together.

  In FIG. 1 b, when the key hole 8 of the inner cylinder 7 exists at the off operation position 11 of the outer cylinder 6, the tip of the movable piece 10 protruding from the switch body 17 of the switch button 15 in the lock switch 2 is the switch body 17. The switch body 17 is touched or contacted with the switch body 17. When the tip of the switch button 15 is pushed in the direction of the switch body 17, the switch button 15 pushes the movable contact 21 connected to the common contact 18, and the movable contact 21 leaves the normal close contact 19 and connects to the normally open contact 20. Is done.

  In FIG. 1 c, when the key hole 8 of the inner cylinder 7 is present at the ON operation position 12 of the outer cylinder 6, the movable piece 10 is separated from the switch button 15, and the tip of the switch button 15 is a spring or movable contact outside the figure. The movable contact 21 protrudes from the switch body 17 by its own spring force, and the movable contact 21 is separated from the normal close contact 19 and connected to the normal close contact 19 by a spring not shown or the spring force of the movable contact 21 itself. The lock switch 2 is used as a normally open type in which a common contact 18 and a normally open contact 20 are individually connected to input ports 22; 23 of an input interface for a CPU (not shown) in the control device 5.

  In short, the best mode is to touch the switch body 17 by pressing the switch button 15 of the lock switch 2 in the direction of the switch body 17 as the movable piece 10 rotates from the on operation position 12 to the off operation position 11. As the movable piece 10 rotates from the off-operation position 11 to the on-operation position 12, the pressing of the switch button 15 of the lock switch 2 in the direction of the switch body 17 is released to move away from the switch body 17. Further, the movable piece 10 and the lock switch 2 are characterized in that they are installed inside the mechanism housing 101 shown in FIG.

  Therefore, as shown in FIG. 1 a, when the keyhole 8 of the setting lock 1 exists at the off operation position 11, the movable piece 10 pushes the switch button 15 and comes into contact with the switch body 17. Therefore, even if the unauthorized operation member 28 is inserted through a gap between the closed front frame 103 (see FIG. 4) and the mechanism housing 101 (see FIG. 4), the unauthorized operation member 28 is moved to the movable piece 10 and the switch button 15. Cannot enter between. Therefore, even if the player operates the unauthorized operation member 28 with the hand 16, presses the setting operation unit 3 with the unauthorized operation member 28, and the setting switch 4 outputs the setting signal to the control device 5, the control device 5 is locked. The ON signal from the switch 2 is not input, and the control device 5 does not set permission for the setting change process. For this reason, even if the setting operation unit 3 is pushed by the unauthorized operation member 28, the control device 5 does not execute the setting change process, so that an unauthorized setting change by the player as in the conventional case can be prevented. Further, as shown in FIG. 1 b, in order for the keyhole 8 of the setting lock 1 to be made to exist from the off operation position 11 to the on operation position 12, the key of FIG. Since the rotary operation has to be performed, even if the movable piece 10 is separated from the switch button 15, it is possible to prevent an illegal setting change by a player as in the conventional art. As shown in FIG. 1b, the normally closed contact 19 and the normally open contact 20 of the lock switch 2 are improperly short-circuited in a state where the movable piece 10 of the setting lock 1 exists at the OFF operation position 11. However, since the control device 5 does not set permission for the setting change process, it is possible to prevent an illegal act by a player who changes and sets the probability of winning by lottery.
