On the upper and lower parts of the front frame 2, sashes 4 are provided.
A parallel moving unit is provided which is capable of moving in parallel in the front-rear direction when the front frame 2 is opened and closed. As shown in detail in FIGS. 5 and 6, the parallel moving means includes a parallel link mechanism 12 that supports the sash 4 so that the sash 4 can move in parallel to the front frame 2.
The front frame 2 includes a coil spring 13 as a spring member that biases the sash 4 rearward. The parallel link mechanism 12 includes links 14 that connect the front frame 2 and the sash 4 on both left and right sides of the front frame 2. Coil spring 1
3 is engaged with the support shaft 15 of the link 14 on the front frame 2 side, and urges the link 14 counterclockwise in the drawing.

When the front frame 2 is closed, the sash 4 is wound by the machine frame 1 as shown in FIGS. 3 and 5.
It is pushed into the inner back part of the front frame 2 against the biasing force of 3.
When the front frame 2 is opened, as shown in FIGS. 4 and 6, the sash 4 is pushed rearward in parallel with the front frame 2 via the parallel link mechanism 12 by the urging force of the coil spring 13, so that the outlet 6 is moved to the front. It is designed to be released from the frame 2. Therefore, when the front frame 2 is opened, the sash 4 is automatically opened, so that the transparent plate 5 can be replaced easily and quickly in one step.

7 to 15 show another embodiment of the parallel moving means. In the parallel moving means shown in FIG. 7, a connecting rod 17 for connecting the left and right links 14 is attached to the upper and lower parallel link mechanisms 12 or one of the parallel link mechanisms 12 so that the sash 4 can be moved in parallel more smoothly. In the parallel moving means shown in FIG. 8, the parallel link mechanism 12
A bending and stretching link 18 is used for the. In the parallel moving means shown in FIG. 9, bending and stretching links 18 are provided on the left and right sides of the front frame 2 and the sash 4. A spring member (not shown) that biases the sash 4 rearward with respect to the front frame 2 is incorporated in the bending and stretching link 18. Further, the connecting rod may be installed between the left and right or upper and lower bending links 18. In any of these embodiments, the sash 4 can be automatically opened when the front frame 2 is opened, and the transparent plate 5 can be replaced easily and quickly in one step.

The parallel moving means shown in FIGS. 10 to 13 includes a gear mechanism 20 for converting the opening / closing movement of the front frame 2 into the parallel movement of the sash 4. The gear mechanism 20 includes a curved gear 21 fixed to the machine frame 1 near the hinge 3.
A small diameter pinion 22 rotatably supported by the front frame 2 so as to mesh with the curve gear 21, and a small diameter pinion 22.
The large-diameter pinion 23 is provided coaxially with the large-diameter pinion 23, and the long rack 24 fixed to the side surface of the hinge 3 of the sash 4 so as to mesh with the large-diameter pinion 23 is a long rack.
On the side opposite to the hinge 3, the sash 4 is supported by the front frame 2 so as to be slidable in the front-rear direction by a guide (not shown).

When the front frame 2 is opened, the small diameter pinion 22 is rotated counterclockwise in the figures by the curve gear 21, and the rack 24 is sent out rearward by the large diameter pinion 23, as shown in FIGS. 12 and 13. , The sash 4 is retracted in parallel with the front frame 2, and the outlet 6 is moved to the front frame 2.
It is designed to be released from. Therefore, according to this embodiment as well, the sash 4 is automatically opened when the front frame 2 is opened, and the transparent plate 5 can be replaced easily and quickly in one step.

The parallel moving means shown in FIG. 14 and FIG.
The front frame 2 is provided with a guide mechanism 26 that detachably supports the sash 4 and guides the sash 4 so that the sash 4 can move in parallel. The guide mechanism 26 is composed of four L-shaped guide plates 27 attached to the insides of the corners of the front frame 2 and four rollers 28 pivotally attached to the corners of the sash 4. . The sash 4 is attached to each guide plate 27 via rollers 28.
A downward-sloping inclined groove 29 for guiding the parallel translation in the front-rear direction is formed. The roller 28 is provided in the middle of the inclined groove 29.
A larger diameter insertion / removal section 30 is provided upward, and
A locking portion 31 and a holding portion 32 having a diameter smaller than that of the roller 28 are provided downward at the rear end and the front end of the inclined groove 29, respectively.

Therefore, according to this guide mechanism 26, as shown in FIG.
As shown in FIG. 5A, the roller 28 can be inserted into and removed from the insertion / removal section 30, and the sash 4 can be attached to and detached from the front frame 2. Further, as shown in (b) of the figure, by locking the roller 28 to the locking portion 31, the sash 4 can be arranged at the closed position inside the front frame 2. Further, if the sash 4 in the closed position is pushed backward by hand and the roller 28 is fitted to the holding portion 32 as shown in FIG.
Can be quickly opened to the rear of the front frame 2, and the transparent plate 5 can be easily replaced at this open position.

In the above embodiment, the take-out port 6 is provided at the upper end of the sash 4, but the take-out port is provided on the side surface of the sash on the side opposite to the hinge, and the transparent plate is laterally taken in and out from this side for replacement. You can also Also, FIG. 14 and FIG.
When the guide mechanism 26 shown in FIG. 2 is used, the transparent plate 5 may be fixedly attached to the inside of the sash 4, and the integrated product may be detached from the front frame 2 to be replaced. In addition, the present invention may be applied to various game machines such as a slot machine and the like, and the shapes and configurations of the respective parts may be appropriately changed and embodied without departing from the spirit of the present invention.
