(Operation of Example)
Next, the operation of the upper ball tray unit of the pachinko machine configured as described above will be described. When a player inserts a prepaid card into the card insertion slot 19a of the card unit 19 and presses the ball lending button 83 of the ball lending operation unit 81 disposed on the upper ball tray unit 15, The ball paying device is activated, and a predetermined number of pachinko balls S are supplied to the ball storage portion 46 of the ball receiving tray portion 45 through the communication tube portion 34a (feed port 34). The pachinko balls S fed to the ball reservoir 46 roll along the inclination of the ball tray 45 toward the ball rectifying passage 47 and are aligned in a row. In this state, when the player operates the hitting ball launching device 20, the ball feeding device 30 sends out the pachinko balls S in the ball receiving tray 45 to the hitting mechanism one by one through the ball intake 35. . The bottom surface of the ball tray 45 is formed so as to incline downward as it goes rightward, and the ball rectifying passage 47 is formed on the downstream side thereof, so that the pachinko ball S fed to the ball tray 45 is provided. Can be taken into the plane exactly one ball at a time. In addition, since the LED 79 is arranged on the rear side of each elongated hole 23a opened in the bulging portion 23 of the cover member 21, the LED 79 can be turned on to light up and decorate the upper ball tray unit 15. , The decorativeness of the game is improved.

  By the way, when the pachinko machine 10 is used for a long period of time, the ball lending operation unit 81, the lamp unit 68, the ball removal mechanism 57, or the ball removal device disposed in the accommodation space 22 of the upper ball tray unit 15 is used. The button 88 may be in trouble such as failure or damage. In this case, the locking means 18 is operated to release the engagement between the locking means 18 and the locked portion 39 of the rear plate member 31 (upper ball dish unit 15), and the cover member 21 is formed. The entire upper ball tray unit 15 is rotated around the pivot 28a to open the back side of the upper ball tray unit 15 (see FIG. 10). In this state, by removing a screw for fixing the cover member 21 and the rear plate member 31, and pulling the rear plate member 31 to the rear side (the middle frame 12 side), the first support shaft in the hinge mechanism 51 is drawn. 52 slides relative to the connecting member 54 and is displaced from the first state in which the rear plate member 31 is in contact with the rear side of the cover member 21 to the second state in which the rear member 31 is separated from the cover member 21 ( (See FIG. 11). Next, the housing space 22 is completely opened by rotating the rear plate member 31 toward the middle frame 12 with respect to the cover member 21 (see FIG. 12). As described above, the cover member 21 and the rear plate member 31 are pivotally supported via the hinge mechanism 51 so that the rear plate member 31 is simply rotated with respect to the cover member 21. The accommodation space 22 defined between the members 21 and 31 can be opened.

  That is, the parts 57, 68, 81, 88 arranged in the accommodation space can be exchanged without disassembling the cover member 21 and the rear plate member 31, so that the parts 57, 68, 81, 88 can be performed. Can't be lost or accidentally dropped and damaged. Further, as described above, the cover member 21 and the rear plate member 31 are connected together via the hinge mechanism 51, so that the rear plate member 31 is only rotated after being once separated from the cover member 21. Thus, the storage space 22 can be easily opened, work time can be shortened and work efficiency can be improved, and both members 21 and 31 can be prevented from being damaged when opened, thereby reducing waste and cost. It becomes possible to reduce. When removing the screws for fixing the cover member 21 and the rear plate member 31, it is only necessary to remove the screw indicated by the mark 43 of the metal plate member 40. Can prevent the removal of different screws.

  Then, after the ball tray 45 is once separated from the ball tray notch 24 of the cover member 21, the rear plate member 31 is rotated, so that the cover member 21 and the ball tray 45 interfere with each other. Matching is prevented, and the rear plate member 31 can be smoothly rotated. The hinge mechanism 51 includes first and second support shafts 52 and 53 pivotally supported by the cover member 21 and the rear plate member 31, a shaft hole 54 a through which the support shafts 52 and 53 are inserted, and a guide. The connecting member 54 is formed with a hole 54b. Thus, since the hinge mechanism 51 has a simple configuration with a small number of parts, the parts cost can be kept low and the assembling work can be easily performed. Further, in the state in which the rear plate member 31 is held in the first state, the connecting member 54 is substantially parallel to the rear plate member 31, so that the upper ball tray unit 15 (base portion 28) is always provided. The size in the front-rear direction can be reduced, and the degree of freedom in design of the upper ball tray unit 15 is increased.

  Further, the engaging rail portion 41 of the metal plate member 40 disposed on the back side of the rear plate member 31 is engaged with the engaging portion on the lower edge of the front frame 13, and the upper rail plate 41 is engaged with the engaging rail portion 41. Since the gap formed between the unit 15 and the middle frame 12 is shielded, foreign matter can be prevented from being inserted into the pachinko machine 10 through the gap, and illegal acts can be prevented. Further, since the rear plate member 31 (upper ball tray unit 15) is reinforced by the metal plate member 40, the rear plate member 31 (upper ball tray unit 15) can be prevented from being deformed. Since the second support shaft 53 pivotally supported by the rear plate member 31 is fixed by the metal plate member 40, there is no need to separately provide a fixing means for fixing the second support shaft 53. Can be reduced.

  Further, since the turning range of the rear plate member 31 is restricted by the bent portion 42 formed in the metal plate member 40, the housing space is opened in a state where the rear plate member 31 is opened at a predetermined position. Since the ball lending operation unit 81, the lamp unit 68, the ball removal mechanism 57, or the ball removal button 88 accommodated in the ball 22 can be attached and detached, the work efficiency is improved. Furthermore, since it is not necessary to provide another regulating member that regulates the rotation of the rear plate member 31, the cost does not increase. And by forming the said bending part 42, it can prevent more reliably that a foreign material is inserted into the inside of the pachinko machine 10 from the side part of the upper ball tray unit 15, and it is more reliable about an illegal act. Can be prevented.

  By the way, when the pivot 28a and the hinge mechanism 51 are provided on different end sides (one is provided on the left end side and the other is provided on the right end side), the upper ball tray unit 15 (the cover member 21). ) Is turned and the rear side is directed to the front side, and the rear plate member 31 is rotated with respect to the cover member 21 in this state, the housing space 22 is opened to the rear side, and the workability is very poor. Become. On the other hand, the upper ball tray unit 15 of this embodiment has a pivot 28a that rotatably connects the cover member 21 and the inner frame 12, and a cover member 21 and a rear plate member 31 that are rotatably connected. Since the hinge mechanism 51 is provided on the same end side (left end portion) of the cover member 21 and the rear plate member 31, the upper ball tray unit 15 is rotated so that the back side faces the front side. By rotating the rear plate member 31 in this state, the accommodation space 22 is opened to the front side. Accordingly, it is possible to easily replace various components housed in the housing space 22. Since the wiring notch 33 is formed on the rear plate member 31 on the side where the hinge mechanism 51 is formed (left side), when the rear plate member 31 is rotated, The introduced wiring does not hinder the work.

  Further, when the ball tray 45 is attached to the cover member 21 side, in order to completely open the accommodation space 22, the ball tray 45 is rotated after the rear plate member 31 is rotated. Must be removed. On the other hand, in the upper ball tray unit 15 according to the present embodiment, since the ball tray portion 45 is attached to the rear plate member 31, the accommodation space 22 can be formed only by rotating the rear plate member 31. It can be fully opened. That is, the ball removal mechanism 57, the lamp unit 68, the ball lending operation unit 81, and the ball removal button 88 can be exchanged without removing the ball receiving tray 45, and the operation is simplified.

  Further, each of the ball removal mechanism 57, the lamp unit 68, the ball lending operation unit 81, and the ball removal button 88 disposed in the accommodation space 22 has a fixing portion 27, which is provided inside the accommodation space 22, respectively. 36, 38, 70, 70b, 70c, 86, and 93 are fixed to the ball removal mechanism 57, the lamp unit 68, the ball lending operation unit 81, and the ball removal button 88. It can be prevented from being removed or replaced with unauthorized parts. Further, the ball removal mechanism 57, the lamp unit 68, the ball lending operation unit 81, and the ball removal button are disposed on the side of the ball rectifying passage 47 having a small width dimension in the front-rear direction and a relatively large space in the accommodation space 22. By arranging 88, the space of the accommodation space 22 can be effectively used, and the upper bowl tray unit 15 can be prevented from being enlarged.

  In addition, since the first flange portion 85 extending outward is formed at the upper end edge of the ball lending operation unit 81, it is inserted into the first mounting hole 25 of the bulging portion 23 from above. As a result, the first flange portion 85 abuts on the upper surface 23b of the bulging portion 23 (cover member 21), and the ball lending operation unit 81 can be easily positioned, and the assembling workability is improved. Further, since the second flange portion 91 extending outward is formed at the lower end edge of the ball removal button 88, the second flange portion 91 is formed on the bulging portion 23 (the cover member 21). The ball removal button 88 can be prevented from coming off by contacting the upper surface 23b (the inner surface of the accommodation space 22). In addition, since the support plate 93 for restricting the downward movement of the ball removal button 88 is disposed inside the accommodation space 22, the rear plate member 31 is rotated so that the ball removal button 88 is Even when the connection between the connecting portion 90 and the actuating member 63 of the ball removal mechanism 57 is released, the drop of the ball removal button 88 is prevented, so that the work efficiency is not lowered.

(Example of change)
In addition, as a structure of a ball | bowl tray unit, it is not restricted to the thing of an Example, A various change is possible. For example, although the hinge mechanism is provided on the left end side of the cover member and the rear plate member, the present invention is not limited to this, and the cover mechanism and the rear plate member may be provided on the right end side. Further, the cover member is pivotally supported with respect to the gaming machine, and the rear plate member is rotated rearward with respect to the cover member via the hinge mechanism. May be pivotally supported by the gaming machine, and the cover member may be rotated forward with respect to the rear plate member by the hinge mechanism. Furthermore, not only the structure which attaches a ball | bowl tray part to a rear-plate member but it can also be set as the structure attached to a cover member. Each of the rear plate member and the cover member can be rotated by an arbitrary angle by changing the shape angle of the bent portion of the metal plate member disposed on the rear plate member.

  In addition, although the said ball saucer part was made to incline downward toward the right direction, you may make it incline below toward the left direction, and it is comprised so that it may incline below toward the center part of a ball | bowl tray part. You can also. That is, the ball tray portion is formed so that its bottom surface is inclined in a predetermined direction, and on the inclined lower end portion side, a ball rectifying path set to a width dimension substantially equal to the diameter dimension of the game ball is formed. The game balls stored in the ball tray portion can be aligned in a line on the ball rectification path, and the game balls can be stably taken into the machine. In this case, the formation position of the ball discharge port is also changed so as to be positioned at the inclined lower end portion of the ball rectification path (ball tray portion).

  The configuration of the hinge mechanism is not limited to that of the embodiment, and any conventional configuration can be used as long as either the rear plate member or the cover member is rotated to open or close the accommodation space. Various configurations can also be adopted. In the embodiment, each of the ball lending operation unit, the ball removing mechanism, and the lamp unit is accommodated in the accommodation space. However, the present invention is not limited to this, and a speaker or the like may be accommodated. It is. In the embodiment, the upper ball tray unit is used as an example of the ball tray unit. However, the upper ball tray unit is not limited to this and may be a lower ball tray unit. In addition, the gaming machine is not limited to a pachinko machine, and may be an arrangement ball machine, a pachinko slot machine, or the like, which is a gaming machine equipped with a ball receiving portion on the front side for storing gaming balls. Any game machine can be suitably employed.
