The present invention relates to a suitable locking device.

[0002]

2. Description of the Related Art A front frame of a gaming machine has one end fixed to a main frame by a hinge, and the other end is a free end which is rotatable with respect to the main frame. A locking device that enables locking with the main body frame is provided. As such a locking device, for example, registered utility model No. 250845
In Japanese Patent Laid-Open No. 2 (1994), a locking rod is provided inside a base frame body having an L-shaped cross section for a mounting plate and a supporting plate so as to be vertically slidable along the supporting plate, and the locking rod is provided by a tension spring. Upper and lower ends of the locking rod are connected to a hook member that is biased upward and pivotally supported on the upper and lower portions of the support plate, and a cylinder lock is provided on the mounting plate in the middle of the mounting plate. There is described a structure in which a cam plate that is attached so as to be inserted inward from the hole and a cam plate that engages with the locking rod is fixed to the tip of the lock shaft.

In a gaming machine provided with such a locking device, when a hinge is used as a fulcrum to press to close the front frame, the hook member comes into contact with the receiving metal fitting provided on the main body frame, and the hook member is released. When the locking rod slides downward as it tilts upward and the front frame is further pressed and closed, the locking rod returns to the locking position due to the restoring force of the tension spring, the hook member engages with the receiving metal, and the front frame is engaged. Is locked to the body frame. Then, insert the key into the cylinder lock, rotate the cam plate in the unlocking direction by the key operation, slide the locking rod, release the engagement between the receiving bracket and the hook member, and use the hinge as the fulcrum to front frame. Can be opened. Many such gaming machines are installed and used in pachinko parlors, game centers, etc., but the trouble occurs due to the individual gaming machines being in a usable state, or for some reason, waiting or It has become necessary to manage whether or not a trouble is being processed by a computer or the like. Therefore, the closed / open state of the front frame with respect to the main frame is electrically detected.

For example, in Japanese Utility Model Registration No. 2547830, as shown in FIG. 14, a bracket 52 fixed to a base frame 51 is operated in response to a swing member 53 and the swing of the swing member. There is described a structure in which a non-contact switch 54 is provided, and a receiving portion 55 on the main body side is provided with an abutment portion 56 for abutting and rocking the rocking member 53. According to this, when the front frame (not shown) is closed to the main body side, the swing member 53 strikes against the contact portion 56 of the receiving bracket 55 on the main body side and swings, whereby the non-contact switch 54.
Is operated and the front frame is opened, the swing member 53
Oscillates in the opposite direction and the non-contact switch 54 is actuated in the opposite direction accordingly, so that a signal indicating the closing and opening of the front frame is obtained from the non-contact switch 54. Such a locking device is bulky because the swinging member for actuating the non-contact switch protrudes toward the main body side, and the front frame is opened to allow various types of game machines provided on the back side of the front frame. It is necessary to pay attention to the work such as installation, adjustment and replacement of the equipment and parts, and the operator often gets injured by the finger swinging on the swinging member. Further, in the locking device having such a structure, the number of the constituent parts is large and the cost is increased.

In a gaming machine that employs such a locking device, when the front frame is opened for an unauthorized purpose by some method, for example, the use of an unauthorized copy of the master key, the swing member is moved to the front. Since it projects to the back side of the frame, you can easily swing the swinging member with your finger, etc.
Although the front frame is not closed to the main body side, the non-contact switch can be operated in the same manner as when the front frame is closed to the main body side. If the swinging member is fixed with adhesive tape or the like so as to maintain that state, the operation of the non-contact switch is the same as when the front frame is closed to the main frame, even if the front frame is left open. It is possible to illegally operate devices and parts arranged on the back surface of the front frame.

[0006]

The present invention was created as a result of earnest research in view of the above-mentioned actual circumstances,
The number of parts is small, the structure is simple, and it is compact, and it does not hinder the work such as installation, adjustment, and replacement of various devices and parts for game machines, and there is no risk of injury to workers. The purpose is to provide the device at low cost. Further, it is also an object to provide a locking device for a gaming machine in which an illegal operation or the like is difficult to be performed when the front frame is opened for an illegal purpose.

At this time, the switch actuating member slides along the supporting plate against the biasing force of the second tension spring from a position where the inclined edge of the switch actuating member abuts the receiving metal fitting and unlocking is confirmed. The lock of the front frame is confirmed by operating the switch. On the other hand, in the locked state,
When the cylinder lock is unlocked by using the key, the locking rod disengages the upper and lower hooks from the receiving metal fitting along the support plate against the biasing force of the first tension spring. It is unlocked by sliding to the position and then opening the front frame. At that time, the switch actuating member is slid back by the urging force of the second tension spring as the front frame is opened, and the switch is operated to confirm that the front frame is unlocked. According to this configuration, as will be apparent from the embodiments described later, the locking device can be made compact without being bulky, and the front frame is opened, and the gaming machine provided on the back face of the front frame. Installation and adjustment of various equipment and parts for
There is no hindrance to work such as replacement, and there is no risk of an operator getting injured by catching a finger or the like. Further, the structure is simple, the number of parts is small, and the cost is low.

The switch operating member has a plate portion having an inclined edge that abuts against the receiving metal member and an operating portion of the switch, the plate portion facing the hook portion of the locking rod, It is preferable that it is slidably disposed between the locking rod and the support plate. According to this, even if the front frame is opened for an unauthorized purpose, the plate portion of the switch operating member faces the hook portion of the locking rod and is slidably disposed between the locking rod and the support plate. Therefore, it is difficult for the finger or the like to slide the switch operating member against the biasing force of the second tension spring, and it is also difficult to keep the switch operating member in the sliding state. , There is no fear that an unauthorized operation is performed on a device or a part arranged on the back side thereof.

Further, the switch may be a non-contact switch, and may operate by sensing the presence or absence of an operating portion of the switch operating member.
