[Action]

First, to attach the main mechanism covering cover to the mechanism plate, the engaged portion formed on one side of the main mechanism covering cover is engaged with the engaging portion formed on the back plate of the mechanism plate, The positioning recess formed on the other side of the main mechanism cover is engaged with the positioning projection formed on the back of the mechanism plate, and the locking member pivotally supported by the back plate is rotated to rotate the main mechanism cover. This is performed by inserting and locking the locking projection at the tip of the locking member into the locking hole formed in the above. On the other hand, to remove the main mechanism covering cover from the mechanism plate, the locking member is rotated in a direction in which the locking projection is disengaged from the locking hole. Is disengaged. In other words, the main mechanism cover body of the present invention is locked on one side by the engaging portion and the engaged portion in the same manner as in the prior art, but on the other side after being positioned by the positioning recess and the positioning protrusion. Since the locking projections of the rotating locking member are merely engaged with the locking holes, the locking member can be mounted at an accurate position, and the locking member is damaged, so that the cover by the main mechanism cover body can be removed. It is possible to eliminate an accident that the operation cannot be performed, and the operation can be performed extremely easily. In addition, since the locking structure by the locking member is performed by the locking hole and the locking protrusion fitted into the locking hole,
Even if the pachinko machine receives a strong impact from the outside or is used for a long period of time, ensure that the locking mechanism between them does not come off and that the main mechanism is covered with a cover. And the relationship between the locking hole and the locking projection can be stably maintained for a long period of time by the positioning projection and the positioning recess.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the structure of the back surface of a pachinko machine in which a mechanism plate to which a main mechanism covering cover according to the embodiment is applied will be described with reference to FIG. In the figure, pachinko machine 1
A mechanism plate 2 is arranged on the back surface of the device so as to be freely opened and closed. As is well known, the mechanism plate 2 has a prize ball collecting mechanism for collecting prize balls on its front side and a prize ball discharging mechanism for discharging prize balls on its rear side. Specifically, the prize ball collecting mechanism formed on the front of the mechanism plate 2 includes a prize ball collecting gutter 3 for collecting generated prize balls at one place, and a prize ball collected on the prize ball collecting gutter 3. And a winning ball processing mechanism 4 for driving a prize ball discharging mechanism 8 to be described later. Further, a prize ball discharging mechanism formed on the rear surface of the mechanism plate 2 includes a prize ball tank 5 for storing a large amount of prize balls, and a prize ball arrangement for aligning and flowing down the prize balls stored in the prize ball tank 5. A gutter 6, a curve gutter 7 for reducing the ball pressure of the prize balls from the prize ball alignment gutter 6 and supplying the prize balls to a prize ball discharge mechanism 8, and discharging the prize balls supplied by the curve gutter 7 in a predetermined number. Prize ball discharging mechanism 8 and the like.
Further, on the back of the mechanism plate 2, a back plate 9 constituting a rear wall of a prize ball discharge passage for guiding a prize ball discharged from the prize ball discharge mechanism 8 is attached. By the way, on the back of the prize ball discharge mechanism 8 and the prize ball processing mechanism 4 built in the mechanism plate 2, the prize ball discharge mechanism cover 10 and the prize ball processing mechanism cover which constitute the main part of this embodiment are provided. The cover bodies 27 are each detachably attached. The reason why the covering cover body is detachably attached in this manner is that in the case of the prize ball discharging mechanism 8, a well-known prize ball storage cylinder and a vertical stopper member are integrally formed on the support plate 14, and the support plate 14 By locking and fixing with the fixing member 15, it is built in the mechanism plate 2, but the number of prize balls stored in the storage cylinder is changed.
In other words, it is necessary to replace some or all of the prize ball discharging mechanism 8 in order to change the number of prize balls to be discharged. This is because the ball discharge mechanism 8 can be removed from the mechanism plate 2 and replaced. Another reason is that the prize ball discharge device 8 can be repaired when an accident occurs in which the prize ball is not discharged smoothly and the prize ball is not discharged. On the other hand, in the case of the prize ball processing mechanism 4, since the prize balls collected by the prize ball collecting gutter 3 are mechanically processed one by one, the operation of the mechanical part may not be performed smoothly. This is so that it can be repaired when it occurs. Therefore, first, the configuration of the prize ball discharging mechanism covering cover 10 will be described with reference to FIGS. 1 and 2. Are formed in a substantially U-shaped cross section so as to cover the front end thereof, and engagement projections 11a and 11b are provided on both sides of a lower front end thereof so as to protrude downward. The engagement projections 11a and 11b are engaged with engagement recesses 16a and 16b (described later) formed on the back plate 9 to support the lower portion of the prize ball discharge mechanism cover 10 on the back surface of the mechanism plate 2. Has become. Further, a locking hole 12 is formed on the back surface of the prize ball discharging mechanism covering cover 10 at a substantially central position on the upper surface thereof. The locking hole 12 is adapted to be fitted with a locking projection 21 of a locking member 17 described later, which is rotatably provided on the back plate 9. Further, a positioning recess 13 having a predetermined length is cut out at the upper end edge of the prize ball discharging mechanism cover 10. On the other hand, the rear plate 9 has an opening shape without a portion corresponding to the prize ball discharging mechanism 8 as a matter of course, but the engaging recesses 16a and 16b are formed in the rear plate 9 below the opening. Have been. The engaging recesses 16a and 16b are
It is formed in the shape of a socket into which a and 11b are inserted. A locking member 17 is rotatably supported on the rear plate 9 above the opening. As shown in FIG. 2, the locking member 17 has a base 18 formed in a cylindrical shape, and the base 18 is screwed to the back surface of the back plate 9 via a spacing member 19 formed in a cylindrical shape. It is attached rotatably by screwing in. On the back surface of the distal end of the locking member 17, a locking projection 21 is provided so as to project therefrom, and the locking projection 21 fits into the locking hole 12. A positioning projection 22 is provided below the locking member 17 along the opening edge of the opening, and the positioning projection 22 is engaged with the positioning recess 13. As shown in FIG. 1, FIG. 2, and FIG. 4, since the illustrated prize ball discharge mechanism 8 has three rows of prize ball storage cylinders, the prize ball discharge mechanism 8 is discharged from the outermost row of storage cylinders. A prize ball receiving portion 23 for receiving the prize ball and guiding the prize ball to the inside is projected from the back plate 9, and the prize ball discharged from the prize ball discharge mechanism 8 falls toward a bell 25 located below the prize ball. A guiding member 24 for guiding is provided below the prize ball discharging mechanism 8. The prize ball discharging mechanism cover body configured as described above.

Thereby, the winning ball processing mechanism covering cover 27 can be easily attached to the back plate 9. Conversely, when removing the winning ball processing mechanism covering cover 27, first, the locking member 32 is rotated to remove the locking projection from the locking hole 29, and one end of the winning ball processing mechanism coating cover 27 is removed. The engaging projections 28a and 28b are pulled out from the opening edge of the opening 26 by pulling out the winning ball processing mechanism covering cover 27 obliquely and laterally thereafter, and the whole can be removed from the back plate 9. In this manner, the installation of the winning ball processing mechanism cover 27 can be performed extremely easily and smoothly.
Since no excessive force is applied in the attaching / detaching operation, it can be reliably used for a long period of time. In the above-described embodiment, the prize ball discharging mechanism covering cover 10 and the winning ball processing mechanism covering cover 27 are illustrated as the main mechanism covering covers. However, a cover body covering other major mechanisms may be used. Also, the rear plate 9 of the mechanism plate 2 on which the cover body is provided includes a side plate of the mechanism plate 2. In addition, one of the engaging portion and the engaged portion may be configured as a hinge connection, but if not configured so, it is easier to cope with a problem of the main mechanism.

[Effect of the invention]

As is clear from the above description, the main mechanism covering cover body in the mechanism plate according to the present invention has one side,
In the same manner as in the prior art, the locking is performed by the engaging portion and the engaged portion, but the other is positioned by the positioning concave portion and the positioning protrusion, and then locked by the locking convex portion of the rotating locking member. Since it only engages with the hole, it can be mounted at the correct position, and it is possible to eliminate the accident that the locking member is broken and the main mechanism cover cannot be covered. It can be done very easily. Further, since the locking structure by the locking member is performed by the locking hole and the locking projection fitted into the locking hole, the pachinko machine may be used when a strong impact is externally applied or when the pachinko machine is used for a long time. The main mechanism can be reliably covered with the cover, and the relationship between the locking holes and the locking projections can be determined. The projections and the positioning recesses can be stably maintained for a long time.
