It can be engaged with the engagement groove 11b of No.1.

Next, the first embodiment of the front panel locking device will be described. Reference numeral 17 denotes a guide piece fixed perpendicularly to the open back end of the front panel 7, and has a LL-shaped cross section. Screws 18 and 18 are attached to the front panel 7 at the horizontal portion 17a, while a recessed portion 19 is provided horizontally in the center of the vertical portion 17b.

Reference numeral 20 denotes a movable piece arranged in parallel to the inner surface of the guide piece 17 so as to be able to move up and down, and vertically elongated guide holes 21 and 21 penetrated through the upper and lower parts of the movable piece 20 are located at the upper and lower ends of the vertical part 17b of the guide piece 17. They are guided by guide pins 22, 22 planted nearby.

An L-shaped operation knob 20a is projected from the upper part of the movable piece 20, while a recess 20a is provided at the rear end of the central part.
b is horizontally recessed.

Reference numeral 23 denotes a locking projection protruding vertically outward from the base end of the recess 20b of the movable piece 20, and is capable of engaging with the locking portion 10 of the base piece 8.

A spring 24 is hung between the horizontal portion 17a of the guide piece 17 and the lower end of the movable piece 20, and urges the movable piece 20 upward.

Next, the operation and effect of the first embodiment of the front panel locking device having the above-described structure will be explained.

First, when opening the closed front panel 7, when the operating knob 20a is pressed and the movable piece 20 is moved downward, the latching protrusion 23 of the movable piece 20 engages the latching portion 10 of the base piece 8. As the base piece 8 and the movable piece 20 are separated from each other,
The lower end edge of the latch protrusion 23 rubs against the lower guide edge 9C of the latch hole 9 and is guided forward, so that the front panel 7 is pushed forward (see FIG. 5).

On the other hand, when closing the open front panel 7, when closing the front panel 7 while pressing, the upper end edge of the latch protrusion 23 slides against the upper guide edge 9a of the latch hole 9 and moves downward. As a result of being pushed, the movable piece 20 is moved down against the spring 24, and the latching protrusion 24 is engaged in the latching part 10. As a result, the state of engagement of the movable piece 20 with the base piece 8 is changed. The front panel is locked and the closed state of the front panel relative to the window frame 4 is locked (see FIG. 4).

Therefore, the front panel 7 can be easily moved by operating the movable piece 20.
While the front panel 7 can be unlocked, the front panel 7 can be reliably locked simply by pressing the front panel 7 to close it.

Next, the second embodiment of the front panel locking device will be explained according to FIG. Hole 9A
, 9A are arranged vertically in a concave shape, while latching protrusions 23A, 23A are respectively protruded from the upper and lower parts of the movable piece 20A, which is arranged parallel to the outside of the guide piece 17A provided on the front panel 7A. , latching portions 10A formed in both latching holes 9A,
It is configured to be releasably engaged with the IOA.

Therefore, in the second embodiment, the front panel 7A (7) can be locked and unlocked more reliably.

Note that other functions and effects are substantially the same as those of the first embodiment, and therefore their explanations will be omitted.

That is, in the present invention, a concave hook part 10 is installed vertically at the lower part of the base piece 8 which is attached to the inner surface of the open side of the window frame of the pachinko machine, and the base piece 8 is hinged to the lower part of the window frame so as to be openable and closable. Front panel 7
A guide piece 17 is fixed to the back end of the open side of the movable piece 20, and the guide piece 17 has a latch protrusion 23 that is removably engaged with the latch part 10. The locking devices are movably arranged side by side, and the front end of the base piece 8 is recessed with a locking hole 9 having an inclined upper guide edge 9a and a lower guide edge 9C on the upper and lower edges. The latching portion 10 is recessed in a vertically elongated manner behind the guide edge 9a, and the upper end of the latching portion 10 projects above the rear end of the inner edge of the upper beam to form a hook-shaped latching claw 9b; The guide piece 17 is bent into a cross-sectional shape, and a recess 19 is formed in the vertical portion 17b for inserting the locking protrusion 23 of the movable piece 20.
A guide pin 22 for guiding the guide hole 21 of the movable piece 20 is provided in a protruding manner, and the movable piece 20 has a manual operation knob 20a bent at the top thereof, and a recess 20b recessed on the rear side. The front panel locking device for a pachinko machine is designed so that the front panel can be reliably locked and unlocked with respect to the window frame by having a vertically elongated locking protrusion 23 that is bent outward. This is an excellent idea that is extremely practical.
