Description

  The present invention relates to a locking device for a gaming machine.

  A locking device for a gaming machine is known as a device that locks a gaming machine main body and a front door supported on the front surface of the gaming machine so as to be opened and closed. Specifically, the locking device generally includes a pair of upper and lower hook members, a link, and a lock member. Each flange member rotates about a fulcrum as an axis, thereby being locked and detached from the locked member attached to the front door. The link can be reciprocated in the vertical direction, and each flange member is attached to both ends of the link. The locking member is installed on the front door and is rotated when unlocked. The lock member transmits the rotational movement of the key to the link and moves the link upward or downward.

  According to this locking device, when the unlocking member is operated with the key during normal unlocking, the link moves upward or downward, and the hook members at both ends are interlocked to rotate around the fulcrum to move from the locked member. break away. However, in this locking device, when a force is applied from the outside through the gap between the front door and the gaming machine main body in the direction of rotating the hook member in the direction of disengagement from the locked member using a wire such as a wire. May be transmitted to the other hook member via the link, and the hook members may be detached from the respective locked members and illegally unlocked.

As a locking device for coping with such a problem, devices described in the following patent documents are known.
Japanese Patent No. 3437543 JP 2000-288214 A

  Therefore, in order to reliably prevent such unauthorized unlocking, the present invention is simpler and includes a mechanism that does not transmit the power to at least one saddle member when an external force that promotes rotation is applied to the saddle member. It is an object of the present invention to provide a gaming machine locking device that can cope with various types of gaming machines.

  It is another object of the present invention to provide a gaming machine locking device that has a higher crime prevention capability that can detect unauthorized operations.

  The gaming machine locking device of the present invention is a gaming machine locking device having a gaming machine main body and a front door, and a plurality of locked members fixed to either the gaming machine main body or the front door. A locking member that is opened and closed by a key fixed to the other of the gaming machine main body and the front door, and an unlocking member that is reversibly driven by the locking member and has the same number of elongated holes as the number of the locked members; The unlocking member includes a hook member supported to be relatively movable on the other side and engaged with and disengaged from each of the locked members, and a one-way pin driven only at one end of the elongated hole of the unlocking member. A plurality of links for transmitting only movement to each of the flange members.

  The gaming machine locking device of the present invention may include a relative movement detection sensor that detects relative movement between the unlocking member and each of the links.

  In the locking device of the present invention, the link has a one-way pin that is driven only at one end of the elongated hole of the unlocking member. With this one-way pin, only movement in one direction is transmitted between the link and the unlocking member. That is, only the movement of the unlocking member is transmitted to the link, and no movement is transmitted from the link to the unlocking member. For this reason, even if an unauthorized unlocking operation is performed on the collar member from the outside, the movement of the collar member is interrupted between the unlocking member and the link and is not transmitted to the unlocking member. For this reason, since other saddle members are not interlocked, unauthorized opening of the front door can be prevented. Further, by using links having different lengths, it can be easily used as a locking device for gaming machines having different shapes and dimensions, and is highly versatile.

  In the gaming machine locking device of the present invention, there is little or no relative movement between the unlocking member and the link when operating with a regular key. However, when the collar member is operated, the link moves greatly with respect to the unlocking member, and the relative movement between the unlocking member and the link increases. By detecting this movement with a relative movement detection sensor, an unauthorized operation can be known.

  Embodiments of the present invention will be described below with reference to the drawings. This locking device is used in the gaming machine shown in FIG. 1, and this gaming machine includes a gaming machine main body 1, a front door 2, and a locking device 3 provided thereon. A main part of the locking device 3 is provided on the front door 2, and two locked members 4 are provided on the gaming machine main body 1.

  As shown in FIG. 2 as a side view of the main part of the locking device 3 and as shown in FIG. 3 as a rear view thereof, this locking device includes two locked members 4 provided in the gaming machine body 1 and a front door. 2 includes a locking member 5, an unlocking member 6, two links 7, and two hook members 8.

  The lock member 5 is fixed to the peripheral frame portion of the front door 2 with screws 21. The lock member 5 includes a shaft portion 51 that can be swung by a key (not shown) and a cam plate 52 that is fixed to the tip of the shaft portion 51.

  The unlocking member 6 is housed in a shallow recess 22 in the peripheral frame portion of the front door 2. The recess 22 is longer than the longitudinal direction of the unlocking member 6 and has a width that does not hinder the movement of the unlocking member 6. The unlocking member 6 is formed of a rectangular metal plate, and has an engagement hole 61 through which the tip of the cam plate 52 is inserted and elongated holes 62 and 62 provided at both ends, respectively. When the unlocking member 6 is rotated by a key, its cam plate 52 is engaged through the engagement hole 61 and is pushed in the longitudinal direction. In addition, the longitudinal direction of the long holes 62 and 62 and the direction in which the unlocking member is pushed and moved are parallel to each other.

  The flange member 8 is formed of a metal plate having a locking groove 81 on one end side, and a tip side portion of the locking groove 81 serves as a hook 82. The hook 82 is locked with the locking portion of the locked member 4 so that the front door 2 and the gaming machine main body 1 are locked. The flange member 8 is pivotally supported by the shafts 23 and 23 of the peripheral frame portion of the front door 2 at its center portion. Further, the flange member 8 is slidably connected by a link 7 and a shaft hole 83 which will be described later. Further, the flange member 8 is urged by a coil spring 84 in the clockwise direction in the figure.

  The link 7 is formed of a metal rod, and one end of the link 7 is bent in a right angle direction so as to have a function as a shaft portion and is fitted into the shaft hole 83 of the eaves member 8. The other end portion has a function as the engaging pin 71, and a cap is fixed to the tip so as not to fall out from the long hole 62. The engaging pin 71 is always in contact with the inner peripheral surface of one end of the long hole 62 by the biasing force of the coil spring 84.

  The locking device of the present embodiment has the structure described above.

  In this locking device, when the locking member 5 is rotated with a key (not shown), the cam plate 52 shown in FIG. 3 is rotated in the clockwise direction, and the unlocking member 6 is pushed down through the engagement hole 61. The movement of the unlocking member 6 presses the engagement pin 71 of each link 7 at the inner peripheral end face on the upper side of the two long holes 62, 62, and the two links 7, 7 are pushed downward. By the movement of the links 7 and 7, the left end portions of the eaves members 8 and 8 move downward, and the eaves members 8 and 8 swing around the shafts 23 and 23, respectively. As a result, the hooks 82, 82 of the saddle members 8, 8 are separated from the locking portions of the locked members 4, 4, the locking between the front door 2 and the gaming machine main body 1 is released, and the front door 2 is connected to the gaming machine main body. 1 can be opened.

  When the lock member 5 is turned by the key and the key is pulled out of the lock member 5, the hook members 8 and 8 are returned to the positions shown in FIGS. 2 and 3 by the coil springs 84 and 84, respectively. In the locking device of this embodiment, when the opened front door 2 is pressed against the gaming machine body 1 and the door is closed, the hook members 8 and 8 are pushed by the locking portions of the locked members 4 and 4 and swing. , And automatically locked to the locking portions of the locked members 4 and 4.

  Next, a case where one of the flange members 8 is illegally rotated will be described.

  When the upper hook member 8 in FIG. 2 is rotated against the urging force of the coil spring 84 with a wire or the like, the upper hook member 8 rotates in the counterclockwise direction. This rotation pushes down the upper link 7. The engagement pin 71 fixed to the link 7 also moves downward together with the link, but the engagement pin 71 moves downward in the elongated hole 62 of the upper elongated hole 62 of the unlocking member 6. While the engagement pin 71 moves from the upper end side to the lower end side within the elongated hole 62, the engagement pin 71 cannot press the unlocking member 6 and the unlocking member 6 does not move. Since the unlocking member 6 does not move, the lower link 7 and the lower hook member 8 do not move. For this reason, the lower hook member 8 remains locked with the locked member 4 of the gaming machine body 1 and is not unlocked. For this reason, even if the upper unlocking is performed, the lower door is not unlocked, so the front door 2 cannot be opened from the gaming machine main body 1. This can prevent unauthorized opening.

  In the locking device of this embodiment, the link 7 can be easily used as a locking device for other types of gaming machines by changing the length of the link 7. For this reason, versatility is high. The link 7 is formed by bending a metal rod. By forming with a metal rod, compared to a conventional link that cuts out and bends a plate material, it is easy to deal with forming and design changes, and can be made more versatile.

  Furthermore, in the locking device of the present embodiment, the unlocking member 6 is accommodated in the shallow concave portion 22 of the peripheral frame portion of the front door 2. In other words, the unlocking member 6 is surrounded by the peripheral frame portion of the front door 2 having the concave portion 22 and the inner surface of the six surfaces is surrounded, which makes it difficult to perform unauthorized operations from the outside. Therefore, it is effective for an attempt to unlock the unlocking member 6 by illegally driving it.

  A sensor 9 shown in FIG. 4 can be provided as a sensor for detecting an unauthorized operation. The sensor 9 includes a pin-shaped terminal 91 provided on the unlocking member 6 and a spring terminal 92 formed of a thin spring plate provided on the link 7. When the unlocking member 6 and the link 7 move relative to each other, the terminal 91 comes into contact with the spring terminal 92 and electricity is conducted. Thereby, for example, an alarm can be sounded. The sensor 9 is not limited to that shown in FIG. 4, and may be any sensor that can detect the relative movement of the unlocking member 6 and the link 7.

It is a perspective view of the gaming machine used in the example. It is a side view of the locking device of an Example. It is a reverse view of the locking device of an Example. It is a side view which shows the principal part of the locking device with a sensor.
