Description

  The present invention relates to an unlocking device essential for a gaming machine such as a pachinko machine or a slot machine installed in a hall, and more particularly to an electric unlocking device for a gaming machine of a built-in motor type.

The gaming machine is standardly equipped with a locking mechanism for locking the glass window and the frame, and a manual unlocking device for inserting and rotating a key to release the lock.
The basic mechanism of the locking device and unlocking device has been established, but the shape is slightly different for each model and manufacturer, and there are several types of keys used.
In order to eliminate compatibility with keys used in other halls even if the keys are of the same type, security measures are taken so that they cannot be operated unless the key numbers match.
For this reason, in halls where gaming machines of different types are installed, hall attendants end up carrying multiple keys.
Therefore, when installing in halls, the standard unlocking device was replaced with an unlocking device dedicated to each hall to unify the keys.

By unifying the keys, the number of keys to be carried decreases, but the operability is still not improved because the keys have to be turned.
Therefore, as described in Patent Document 1 and Patent Document 2, an electric unlocking device that releases a lock by a motor has been proposed.
Since the device described in Patent Document 1 is specialized for the electric type ignoring the conventional manual unlocking device, the basic structure is completely different from the standard device.
Therefore, even a part of the standard equipment cannot be used, so in order to adopt the device described in Patent Document 1, it will be replaced with a standard equipment. Considering the trouble of replacement and the cost of the device, it must be said that there is a lot of waste.
The device described in Patent Document 2 is a type in which a locking claw is pulled with a wire and can be unlocked with a manual unlocking device. Although there is an advantage that can be used, in order to use the manual unlocking device in the hall, it is necessary not only to newly install another device but also to change the unlocking device.
Considering the actual situation where the standard unlocking device has been replaced for use in the hall, if the motor is built into the unlocking device, it will be electrified at the time of replacement. Two birds with one stone because it can be done together.

The gaming machine is devised so that the inside is not tampered with from the side or the back side, and the internal operation is possible only when the locking device is unlocked and the glass window or frame is opened.
The built-in type electric unlocking device has a structure in which the locking of the glass window and the frame body is released by rotating the cam with the claw interlocked with the locking device by a predetermined angle in a predetermined direction by the motor. In order to be able to operate the inside of the game machine other than forcibly opening the game machine itself, it becomes impossible to release the lock due to malfunction or a malfunction between the claw cam and the locking device. There was no.
If you forcibly open it, there is a high possibility of ruining the gaming machine even if you work carefully over time.

  The present invention is an electric motor-operated unlocking device for a gaming machine (hereinafter simply referred to as an unlocking device) capable of recovering a gaming machine with minimal damage even when unlocking becomes impossible. The structure is such that a rotation shaft in which a cam with a claw is attached to a tip protruding from the housing and a motor for rotating the rotation shaft are incorporated in the housing. When the moving shaft is connected with a detachable coupling and the surface opposite to the rotating shaft protruding side in the housing is released, the motor can be removed from the releasing surface.

  The motor can have a structure in which a lead wire for power supply can be removed, a part to be a release surface can be easily broken, or a structure closed by a lid.

  Since the unlocking device is assembled without exception, the surface opposite to the rotating shaft protruding side in the housing is exposed on the front surface of the gaming machine, the unlocking device of the present invention falls into a situation where it cannot be unlocked. Then, only the portion exposed from the gaming machine is destroyed or released by pushing it open, and the lock can be forcibly released by extracting the motor and directly rotating the rotating shaft.

  If the lead wire for power supply can be removed, the motor can be removed and removed smoothly, and the part that becomes the release surface can be easily broken, or if it is closed with a lid, the unlocking device Damage can be minimized.

An unlocking device according to the present invention will be described with reference to the drawings.
FIG. 1 shows an unlocking device according to the present invention. In this unlocking device, a mounting flange 2 is fixed to one end surface of a housing 1, and the unlocking device is rotated from the surface to which the flange 2 is fixed. The moving shaft 3 protrudes.
The rotating shaft 3 can be attached with a cam 4 with a claw at the projecting tip portion. The cam 4 with the claw is a cam 4a. With a claw removed from a manual unlocking device provided as a standard. 4b. From 4c, the one attached to the manual unlocking device mounted on the table is used as it is.
Further, in the housing 1, a motor 5 is incorporated in a cylindrical portion in which a lock (cylinder key) is incorporated in a manual unlocking device.

The rotating shaft 3 is supported by a bearing (not shown) in the housing 1, and a key 6a is provided on the end surface of the rotating shaft 3 so as to cross the center of the shaft.
Further, the motor shaft 5a is formed with a key groove 6b for fitting the key 6a on the tip surface, and the rotating shaft 3 and the motor 5 are constituted by the key 6a and the key groove 6b. Are connected by a detachable coupling 6.

Reference numeral 7 denotes a lead wire for supplying power to the motor 5. The lead wire 7 is introduced into the housing 1 from the side surface of the flange 2, and a plug 7a is attached to the tip.
On the other hand, the motor 5 is provided with a connector 5b, and the lead wire 7 is detachably connected to the motor 5 by fitting the plug 7a into the connector 5b.
The motor 5 employs a pulse control system, and can always recognize how much angle it is rotating from the reference position in either the left or right direction.

The shape and dimensions of the housing 1 are designed to be compatible with the standard manual unlocking device, and the unlocking device of the embodiment has a cylindrical portion where the motor is incorporated. However, since the protruding portion is incorporated so as to be exposed from the gaming machine, there is no problem when it is replaced with a manual unlocking device.
As shown in FIG. 2, the built-in motor 5 is controlled based on an unlocking signal generated from a remote controller so as to execute an operation according to the rotation of a key manually operated by a controller.

That is, when the unlock button of the remote controller is operated, the controller receives the unlock signal in S1, determines whether the signal requires unlocking of the glass window or the frame, and S3 Alternatively, the motor is rotated in either the left or right direction in S4.
In S5 to check whether the motor has rotated by an angle necessary to release the lock, for example, the shape of the timing cam attached to the rotating shaft is physically detected by a limit switch, magnetic sensor, optical sensor, etc. The number of pulses counted by an encoder attached to the motor shaft is preferably used.
When it is confirmed that the motor has been rotated by a predetermined angle, the motor is temporarily stopped in S6, and a timer for 10 seconds, for example, is operated in S7. When the 10 seconds have elapsed, the motor is reversed in S8 and the reference position is set. Return to.
The same means as the detection of the rotation angle is used to confirm whether or not the position has returned to the reference position. When it is confirmed in S9 that the position has returned to the reference position, the motor is stopped in S10.

In the unlocking device of the embodiment, the surface of the housing 1 opposite to the surface from which the rotating shaft 3 protrudes is sealed by adhering the detachable lid 8.
Therefore, in this unlocking device, a part corresponding to the keyhole in the standard unlocking device is incorporated with a part of the housing protruding in a columnar shape, and a set of unlocking devices such as a motor incorporated in the inside Is completely protected from the outside.

For example, when a motor breaks down so that it cannot be unlocked, the game machine itself has been forcibly opened to operate the internal equipment, but the unlocking device of the present invention is equipped. If it is a gaming machine, the surface is released by forcibly peeling the detachable lid 8, the plug 7 a is pulled out from the connector 5 b, the lead wire 7 is removed from the motor 5, and the motor 7 is pulled to couple The motor shaft 5a and the rotating shaft 3 are separated at the portion 6, so that only the motor 5 can be removed.
When the motor 5 is removed, the joint portion of the coupling 6 can be seen in the back of the housing 1, so that the key 6a can be picked with a tool such as radio pliers and manually rotated.

The embodiment is closed by adhering the detachable lid, but it is closed with a synthetic resin lid, or the portion is made thin, and the lid is removed from the synthetic resin and the motor is removed. You can also
In addition, the structure of the coupling is not limited as long as the motor shaft is separated from the rotating shaft and the motor can be removed, and the lead wire connected to the motor can be freely attached and detached by the plug and the connector. If not, you can disconnect.

  As described in detail above, the rotating shaft can be manually operated by removing the motor, and even if a part of the housing is destroyed at that time, the main body of the gaming machine is not affected at all. If it is replaced with a lock device, the gaming machine can be returned to its original state, and in the worst case, minimal damage such as partial destruction of the housing is required.
