[0026]
Next, the operation of the locking device of the pachinko machine 10 described above will be described.
In a state where the front frame 12 and the glass frame 20 of the pachinko machine 10 are closed and locked, the first movable lock plate 41 and the second movable lock plate 42 of the lock mechanism main body 30 are the first spring 36 and the second It is held at the upper limit position by the force of the spring 37. For this reason, the unlocking shaft 55 at the reference position of the lock body 50 attached to the glass frame 20 is connected to the connecting portion M1 of the first opening 41h of the first movable lock plate 41 and the first movable lock plate 41, as shown in FIG. The second movable lock plate 42 is passed through the connection portion M2 of the second opening 42h.
[0027]
When the cylinder lock 51 is operated by key operation from this state and the rotation shaft 50j of the cylinder lock 51 is rotated to the right in FIG. 4A, the unlocking shaft 55 of the cylinder lock 51 is accordingly moved to the second movable lock. It moves along the lower right arc portion 42e of the second opening 42h of the plate 42. In this movement process, the unlocking shaft 55 of the cylinder lock 51 engages with the L-shaped portion 41r of the first opening 41h of the first movable lock plate 41, and as shown in FIG. The plate 41 is pushed downward against the force of the first spring 36. As a result, the first engaging claw 32 of the locking mechanism main body 30 is disengaged from the first claw support 7 of the machine base frame 11, and the front frame 12 is unlocked.
[0028]
Further, in the process in which the unlocking shaft 55 of the cylinder lock 51 moves along the lower right arc 42e of the second opening 42h of the second movable locking plate 42, the unlocking shaft 55 is the first inclined surface of the guide member 52. The guide member 52 is pushed down against the force of the elastic member 53 while being in contact with 59a and sliding in a direction away from the valley bottom 59v (see FIGS. 1C and 4B). For this reason, after the table frame 12 is unlocked, when the hand is released from the key of the cylinder lock 51, the guide member 52 is pushed up by the force of the elastic member 53, and the unlocking shaft 55 is connected to the first inclined surface 59 a of the guide member 52.

As a result, the unlocking shaft 55 is returned to the original position along the lower right arc portion 42e of the second opening 42h of the second movable locking plate 42, and at the bottom 59v while sliding on the first inclined surface 59a. The position is returned to the position (reference position) (see FIG. 4A).
[0029]
When the cylinder lock 51 is operated by key operation and the rotation shaft 50j of the cylinder lock 51 is rotated to the left in FIG. 4A, the unlocking shaft 55 of the cylinder lock 51 is attached to the first movable lock plate 41 accordingly. It moves along the lower left arc 41e of the first opening 41h. In this movement process, the unlocking shaft 55 of the cylinder lock 51 is engaged with the L-shaped portion 42r of the second opening 42h of the second movable lock plate 42, and as shown in FIG. The plate 42 is pushed downward against the force of the second spring 37. As a result, the second engaging claw 34 of the locking mechanism body 30 is disengaged from the second claw support 28 of the glass frame 20, and the glass frame 20 is unlocked.
[0030]
Further, in the process in which the unlocking shaft 55 of the cylinder lock 51 moves along the lower left arc portion 41e of the first opening 41h of the first movable locking plate 41, the unlocking shaft 55 is connected to the second inclined surface 59b of the guide member 52. The guide member 52 is pushed down against the force of the elastic member 53 while sliding in a direction away from the valley bottom 59v (see FIGS. 1C and 4C). Therefore, after the glass frame 20 is unlocked, when the hand is released from the key of the cylinder lock 51, the guide member 52 is pushed up by the force of the elastic member 53, and the unlocking shaft 55 is moved to the second inclined surface 59 b of the guide member 52. Is pressed upward. As a result, the unlocking shaft 55 is returned to the original position along the lower left arc portion 41e of the first opening 41h of the first movable lock plate 41, and the position of the valley bottom 59v while sliding on the second inclined surface 59b. It returns to (reference position) (see FIG. 4A).
[0031]
Thus, according to the locking device of the pachinko machine 10 according to the present embodiment, the unlocking shaft 55 of the cylinder lock 51 always receives the force in the direction of returning to the reference position by the action of the guide member 52 and the elastic member 53. Therefore, when the cylinder lock 51 is not operated by key operation, the unlocking shaft 55 is always located at the reference position. For this reason, when the glass frame 20 is closed, there is no need to return the unlocking shaft to the reference position by a key operation as in the prior art. That is, simply by closing the glass frame 20, the unlocking shaft 55 of the cylinder lock 51 automatically engages with the receiving portions (connecting portions M1, M2) of the locking mechanism main body 30. Therefore, the operability when closing the glass frame 20 is improved.
[0032]
Further, when the unlocking shaft 55 of the cylinder lock 51 is at the reference position, the unlocking shaft is restrained from the radial direction by the first inclined surface and the second inclined surface, so that the unlocking shaft is in a stable state. It can be held at the reference position.
The cylinder lock 51 is configured to be attached to the glass frame 20 by an attachment member 54, and is inserted into the insertion portion 12h on the front frame 12 side in the process of closing the glass frame 20. A positioning frame 54p is provided. Therefore, unlocking shaft 55 of the cylinder lock 51 is easily fitted into the accepted portion of the locking mechanism body 30 (connecting portions M1, M2) in the course of the glass frame 20 is closed.
[0033]
Here, in this embodiment, the example in which the unlocking shaft 55 of the cylinder lock 51 is in the upper limit position is shown as the reference position of the unlocking shaft 55, but as shown in FIG. The state where the unlocking shaft 55 is in the right limit position can be set as the reference position of the unlocking shaft 55. In this case, it is necessary to shift the attachment positions of the guide member 52 and the elastic member 53 by 90 °.
In this way, by setting the state where the unlocking shaft 55 of the cylinder lock 51 is in the right limit position as the reference position of the unlocking shaft 55, as shown in FIG. The lock main body 50 (cylinder lock 51) may be used for the lock mechanism main body 30 that lifts and unlocks the front frame 12 and depresses the second movable lock plate to unlock the glass frame 20. It becomes possible.
[0034]
Further, in the present embodiment, the cylinder lock 51 having one unlocking shaft 55 on the cam plate 50b of the rotating shaft 50j has been described as an example. However, as illustrated in FIG. It is also possible to provide two unlocking shafts 55 at positions facing each other across the axis. In this case, the guide member 52 may be configured so that only the unlocking shaft 55 on one side can be returned to the reference position. Thus, by providing the two unlocking shafts 55, the first movable lock plate 41 is pushed up to unlock the front frame 12, and the second movable lock plate is pushed up to unlock the glass frame 20. The cylinder lock 51 can be used for the locking mechanism main body 30 of the method of performing the above.
[0035]
In the present embodiment, the guide member 52 is moved to the upper limit position (the right limit position in FIG. 6) by the elastic member 53 to return the unlocking shaft 55 of the cylinder lock 51 to the reference position. As shown in FIG. 7, elastic members 53u and 53d are provided above and below the attachment member 54, and the unlocking shaft 55 of the cylinder lock 51 is positioned at the reference position when the guide member 52 is at the center position of the attachment member 54. You may do it.
[0036]
Moreover, in this embodiment, although the example which uses the attachment member 54 for the attachment of the cylinder lock 51 and the positioning of the cylinder lock 51 with respect to the locking mechanism main body 30 was shown, as shown to FIG. 8, FIG. It is also possible to fix a frame 27 extending vertically to 54 and to form a claw holder 28 for a glass frame on the upper and lower ends of the frame 27.
Thus, by fixing the frame 27 to the attachment member 54, the glass frame 20 can be reinforced by the frame 27. Further, since the glass frame claw holders 28 are formed on the upper and lower ends of the frame 27, the number of parts on the glass frame side can be reduced.
[0037]
