  As shown in FIG. 4, the launching device 40 includes a base plate 65 (corresponding to the “base member” of the present invention), a firing motor 68 corresponding to the “electric drive source” of the present invention, a striking rod 67, and the like. Assemble and prepare various parts.

  The striking rod 67 has a structure in which a striking portion 67S protrudes from the tip of a substantially strip-shaped main body, and a striking coil spring is fixed to the striking portion 67S. Further, the striking rod 67 is disposed on the rear surface side of the base plate 65, and a rotating shaft 69 penetrating the base plate 65 is fixed at a position near the base end of the striking rod 67. Further, the striking portion 67S faces a striking window 63W (see FIG. 3) formed on the firing rail 63. The rotation shaft 69 is pivotally supported on the base plate 65 by a bearing (not shown), so that the striking rod 67 rotates and the striking portion 67S moves forward and backward to the striking window 63W.

  As shown in FIG. 5, stoppers 77 and 77 are provided on the rear surface of the base plate 65, and the rotation range of the striking rod 67 is restricted by these stoppers 77 and 77.

  As shown in FIG. 4, a resilient element 66 </ b> E through which the rotation shaft 69 passes is attached to the front surface of the base plate 65. The resilient element 66E is formed by sandwiching a torsion spring 66 between a rotating disk 74 laid on the front surface of the base plate 65 and a cylindrical cap 70 fixed to the tip of the rotating shaft 69. The torsion spring 66 is wound around a cylindrical portion (not shown) extending from the cylindrical cap 70 or the rotating disk 74. One end of the torsion spring 66 is locked to the cylindrical cap 70 and the other end is locked to the rotating disk 74.

  The rotating disk 74 is rotatable with respect to the rotating shaft 69, and a gear (not shown) is formed on the peripheral surface of the rotating disk 74. When the operation knob 28 (see FIG. 2) is mounted on the operation knob mounting portion 28T fixed to the front surface of the base plate 65, the operation knob 28 is operated by the gear mechanism including the rack gear 75 and the idle gear 76 shown in FIG.

More specifically, a part of the peripheral surface of the cylindrical body is formed to bulge outwardly in correspondence with the connector connecting portion 78 provided in the firing motor 68 (see FIG. 5). Here, the cover body 45 is large enough to accommodate the firing motor 68 in a non-contact state. Thereby, when the cover body 45 is resin, the deformation of the cover body 45 due to the heat of the firing motor 68 can be prevented. In this embodiment, the cover body 45 and the substrate housing case 42 are not in contact with the outer surface of the firing motor 68 made of at least metal. Therefore, there is no particular problem even if the cover body 45 and the substrate housing case 42 are in contact with the resin connector connection portion 78 and the vinyl harness 48 that are difficult to transmit heat. Also, cover body 45 has its distal end is abutted against the base plate 65 side. This ensures that the game ball is impossible enter from between the tip of the base plate 65 and the cover member 45. Furthermore, as shown in FIG. 6, a rectangular recess 46 for avoiding contact with the screw 46N to which the firing motor 68 is fixed is formed in the tip portion of the cover body 45 that is attached to the flange portion 68F.

  As shown in FIG. 3, a longitudinally long slit 47 (corresponding to the “notch” of the present invention) is formed on the peripheral surface of the cover body 45. These slits 47 are formed at positions where the cover bodies 45 are equally arranged, and are opened at the front end portion of the cover body 45. The widths of the slits 47 are, for example, substantially the same as the radius of the game ball so that the game ball cannot enter the inside of the cover body 45. Thereby, the heat of the firing motor 68 can be efficiently released to the outside of the cover body 45 while preventing the game ball from colliding with the firing motor 68. Of these slits 47, a slit 47A (corresponding to the “harness insertion hole” of the present invention, which is formed in a bulging portion of the cover body 45, that is, a portion in which the connector connecting portion 78 provided in the firing motor 68 is accommodated. 6) is slightly wider than the other three slits 47, so that the harness 48 connected to the connector connecting portion 78 can be inserted. That is, the slit 47 </ b> A allows the heat of the firing motor 68 to escape to the outside of the cover body 45 and allows the harness 48 connected to the firing motor 68 to be drawn out of the cover body 45. Further, since the slit 47A is opened at the tip end side of the cover body 45, when the harness 48 is passed through the slit 47A, when the substrate storage case 42 is fixed to the base plate 65, the tip open portion of the slit 47A is opened. It is sufficient to pass the harness 48 from the top, and workability is improved.

The cover body 45 can be arranged at a position as designed with respect to the firing motor 68.

Now, when the maintenance work of the launching device 40 is performed by interrupting the game by the pachinko gaming machine of the present embodiment, it is as follows. When a game is performed and the firing motor 68 is continuously driven for about 2 hours, the temperature of the firing motor 68 becomes 40 to 50 ° C. In such a situation, the front frame 90 may be opened for maintenance, and an operator's hand may be inserted around the firing motor 68. However, in the pachinko gaming machine according to the present embodiment, since the entire circumference of the firing motor 68 is covered with the cover body 45, the operator's hand can be prevented from directly touching the firing motor 68. Moreover, the space is formed between the firing motor 68 and the cover member 45 and the substrate storage case 42. That is, the cover body 45 is in a non-contact state with respect to the firing motor 68, and the heat of the firing motor 68 is not easily transmitted to the cover body 45. Can be done.

In addition, when the front frame 90 is opened, game balls may spill over the launching device 40, but in the pachinko gaming machine of this embodiment, the periphery of the launch motor 68 is covered by the cover body 45. it is not name that game ball strikes the firing motor 68.

Thus, according to this embodiment, since the cover body 45 covering the firing motor 68 is loosely fitted to the firing motor 68, the heat generated from the firing motor 68 is not easily transmitted to the cover body 45 directly. Accordingly, for example, during maintenance work, it is possible to prevent the operator's hand from directly touching the firing motor 68 and to prevent the operator from feeling uncomfortable when the operator's hand touches the cover body 45. Further, since the front end portion of the cover body 45 is pressed against the base plate 65 side, thereby preventing the collision game ball to the calling morphism motor 68, the hand of man can be prevented from directly touching the firing motor 68 . Further, since the cover body 45 is formed with a plurality of slits 47 in which a game ball cannot enter, the heat of the launch motor 68 is removed from the cover body 45 while preventing the game ball from colliding with the launch motor 68. Can escape efficiently.
