The operation handle portion 21 is unitized by attaching a ring-shaped operation lever 21b to a substantially hemispherical gripping body 21a forming a fixed base, and is detachably fixed to the lower ball tray 16 via screws. It is integrated with the lower ball tray 16. The operation handle portion 21 incorporates a variable resistor and a switch (both not shown) for the rotary solenoid 23 as an electric operation input means inside the grip body 21a. A metal touch sensing ring (not shown) is attached to the outer periphery, and a wiring inserted through the inside of the gripping body 21a is electrically connected to the firing control device 41.

  As shown in FIG. 3 or FIG. 5, the hitting ball drive unit 22 includes a rotary solenoid 23 as a drive source housed in the housing portion 28 a of the installation panel 28 with the rotating shaft 23 a projecting rearward. The reciprocating-type hitting ball 24 connected and fixed to the rotary shaft 23 a of the rotary solenoid 23, and the hitting ball provided at the tip of the hitting ball 24 as the rotary solenoid 23 is driven. The part 24a is swung to a position facing the hitting ball launch position of the launch rail 33. That is, for each energization excitation of the rotary solenoid 23, the hitting portion 24a of the hitting ball 24 can hit the hitting ball launching position on the launching rail 33 and launch the pachinko ball sent to the hitting ball launching position. ing. The rotary solenoid 23 is detachably fixed to a metal-made holding plate 34 that is detachably fixed to the back side of the installation board 28 via screws, so that the entire hitting ball driving unit 22 can be handled integrally. It is like that.

  The firing control device 41 performs overall input / output control of the electrical components of the rotary solenoid 23 and other ball hitting device 20 and the ball feeding device, and is a circuit board (not shown) having a required circuit. In the case body 42 made of synthetic resin molding. The launch control device 41 (case body 42) is pivotally supported on the back side of the installation panel 28 (inner frame 12) via a hinge mechanism 36 so as to be detachable and openable. The firing control device 41 (case body 42) will be described based on a state in which the firing control device 41 is attached to the installation panel 28 as shown in FIG.

  On the right side portion of the facing surface 42c of the case body 42 facing the installation board 28, second support pieces 45, 45 extending toward the front (on the installation board 28 side) are provided at positions spaced apart in the vertical direction. Holes 45a and 45a are formed in each of the second support pieces 45 and 45 so that the shaft parts 28c and 28c of the first support pieces 28b and 28b can be inserted through the second support pieces 45 and 45, respectively. (See FIG. 1, FIG. 6 or FIG. 7). That is, when the holes 45a and 45a are aligned above the shafts 28c and 28c, the case body 42 (launch control device 41) is moved downward to move the shafts to the holes 45a and 45a. The parts 28c and 28c are inserted, and the case body 42 (launch control device 41) is pivotally supported to be openable and closable with respect to the installation board 28 (inner frame 12). Here, the second support pieces 45, 45 of the case body 42 abut on the first support pieces 28 b, 28 b of the installation panel 28, and the downward movement of the launch control device 41 is restricted, and the launch control device 41 is Hold in place. That is, the hinge mechanism 36 that pivotally supports the firing control device 41 so as to be openable and closable is constituted by the shaft portions 28 c and 28 c formed in the installation board 28 and the hole portions 45 a and 45 a formed in the case body 42. .

  Further, as shown in FIG. 1, an inclined surface 43 is formed on the right side surface 42 a of the case body 42. Here, the inclined surface 43 abuts the inclined surface 43 on the left side surface 25a (see FIG. 4) of the recovery rod 25, and the opposed surface 42c of the case body 42 abuts on the first support piece 28b. When this is done, the distance from the left side surface 25a of the recovery bowl 25 to the holes 45a, 45a formed in the case body 42 and the distance to the shafts 28c, 28c formed in the installation board 28 are substantially equal. It is set as follows. That is, the case body 42 is positioned by bringing the inclined surface 43 into contact with the left side surface 25a of the collection basket 25 and bringing the opposing surface 42c of the case body 42 into contact with the first support piece 28b. Each shaft portion 28c and the hole portion 45a can be vertically aligned.

  As shown in FIG. 1 or FIG. 5 to FIG. 7, the left side portion of the case body 42 (that is, the side portion opposite to the side portion where the hinge mechanism 36 is formed) A protrusion piece 46 a is formed at the left end of the protrusion 46 and protrudes forward (on the installation panel 28 side). Here, when the case body 42 (launch control device 41) is rotated in the direction close to the installation board 28 via the hinge mechanism 36, the pair of projecting pieces 46a is formed on the installation board 28. It is set to be inserted between the restricting portions 30 and 30. That is, when the protruding piece 46a is inserted between the restricting portions 30 and 30, the upper and lower edges of the protruding piece 46a contact the restricting portions 30 and 30, and the vertical movement of the firing control device 41 is restricted. It is supposed to be. As shown in FIG. 6 or 7, the upper and lower corners on the front end side of the protruding piece 46a are chamfered, and when the case body 42 is rotated in the direction close to the installation panel 28, The protruding piece 46a can be easily inserted between the restricting portions 30 and 30.

  A hook member (first engaging portion) 47 that is elastically deformable is formed on the left side of the upper surface 42b of the case body 42. As shown in FIG. 6 or FIG. 7, the hook member 47 has a fixing portion 48 fixed to the case body 42, and extends from the upper end of the fixing portion 48 rearward (in a direction away from the installation panel 28). A claw portion 49a is formed on the upper surface side of the main body 49. The claw portion 49a is inclined upward from the front side to the rear side. That is, the main body 49 of the hook member 47 extends upward and parallel to the upper surface 42b of the case body 42 so that the main body 49 can be elastically deformed in a direction close to the upper surface 42b of the case body 42. It has become.

  Here, when the launch control device 41 is rotated toward the installation panel 28 (the inner frame 12) via the hinge mechanism 36, the mechanism is formed on the inclined surface 49b of the claw portion 49a of the hook member 47. It is set so that the lower end edge 19a of the set panel 19 abuts. In this state, by further rotating the launch control device 41 toward the installation board 28, the hook member 47 is pushed downward along the inclination of the inclined surface 49b to be elastically deformed, and the rear of the claw portion 49a. When the lower end edge 19a of the mechanism setting panel 19 reaches the side, the hook member 47 returns and the lower end edge 19a and the claw 49a of the mechanism setting panel 19 are engaged, and the firing control device 41 is installed. It is fixed in a closed state with respect to the back side of the board 28 (inner frame 12). Thus, the mechanism set board 19 functions as a second engagement portion that is detachably engaged with the hook member 47 formed on the case body 42.

  When the firing control device 41 is closed with respect to the installation board 28, the protruding piece 46a provided on the protruding portion 46 of the case body 42 is inserted between the restricting portions 30 and 30. While restricting the vertical movement of the firing control device 41, the projection 46 abuts against the rear end faces 30a, 30a of the restriction portions 30, 30, thereby restricting the rotation of the case body 42 toward the installation panel 28. Yes. Also, as shown in FIG. 1, when the firing control device 41 is fixed to the installation board 28, the hitting ball 24 is positioned in a space 39 defined between the members 28 and 41. The hitting ball driving unit 22 is covered by the closed launch control device 41.

  Further, the hook member 47 is formed with an extending portion 49c extending rearward from the claw portion 49a, and the claw portion 49a is engaged with the lower end edge portion 19a of the mechanism set board 19. At this time, the extending portion 49c extends to the rear side of the mechanism set board 19 (the side away from the installation board 28) (see FIG. 1 or FIG. 7). That is, the hook member 47 is elastically deformed by pushing down the extending portion 49c downward (on the upper surface 42b side of the case body 42), thereby engaging the hook member 47 with the lower edge 19a of the mechanism set panel 19. It can be released.

(Effects of Example)
Next, the operation of the mounting structure of the launch control device in the pachinko machine according to the embodiment will be described. First, a method for attaching the launch control device 41 to the inner frame 12 will be described. Holes 45a, 45a of the second support pieces 45, 45 formed in the case body 42 (launch control device 41) are formed on the first support pieces 28b, 28b formed on the back side of the installation board 28 (inner frame 12). Under the alignment above the shaft portions 28c, 28c, the case body 42 is moved downward to insert the shaft portions 28c, 28c into the holes 45a, 45a. As a result, the launch control device 41 is pivotally supported so as to be openable and closable with respect to the installation panel 28 (inner frame 12) via the holes 45a and 45a and the shafts 28c and 28c (ie, the hinge mechanism 36). The Here, an inclined surface 43 is formed on the right side surface 42 a of the case body 42, the inclined surface 43 abuts on the left side surface 25 a of the collection basket 25 located on the back side of the installation panel 28, and the case body 42. Since the case body 42 is positioned by abutting the opposing surface 42c of the first support piece 28b, the holes 45a, 45a and the shaft portions 28c, 28c can be aligned vertically. A person can save time and labor for accurately aligning the hole 45a and the shaft portion 28c, and the work load can be reduced.

  Further, when the launch control device 41 is pivoted toward the installation panel 28 (inner frame 12) while the launch control device 41 is pivotally supported via the hinge mechanism 36, the case body 42 is formed. The lower end edge portion 19a of the mechanism set panel 19 comes into contact with the inclination of the inclined surface 49b of the hook member 47 (claw portion 49a), and further rotates, whereby the hook member 47 is pushed down and elastically deformed, Finally, the hook member 47 engages with the lower edge 19a of the mechanism set board 19. This restricts rearward movement of the firing control device 41 (movement in a direction away from the middle frame 12), and the protrusion 46 formed on the case body 42 causes the installation board 28 (middle frame 12). The forward movement of the firing control device 41 (moving in the direction approaching the middle frame 12) is restricted by contacting the rear end surfaces 30a, 30a of the regulating portions 30, 30 formed in the 28 is fixed in a closed state. Here, when the firing control device 41 is closed, the firing control device 41 covers the rear of the hitting ball driving unit 22 (the rotary solenoid 23 and the hitting ball 24). It is possible to prevent the pachinko balls dropped from the 19 ball processing units from coming into contact with the hitting ball driving unit 22.

  Further, when the hook member 47 of the case body 42 is engaged with the lower edge 19 a of the mechanism setting panel 19, the firing control device 41 is urged downward by the hook member 47. That is, since the upward movement of the firing control device 41 is restricted, the shaft portion 28c is prevented from coming off from each hole 45a, and the firing control device 41 falls off the installation panel 28 and is damaged. There is nothing. Further, when the launch control device 41 is closed to the installation panel 28, the protruding piece 46a formed on the protruding portion 46 of the case body 42 is inserted between the restricting portions 30 and 30, The case body 42 (launch control device 41) does not move up and down, and the launch control device 41 can be reliably prevented from falling off.

  Here, when the pachinko machine 10 is transported, the pachinko machine 10 is usually placed horizontally to lower the position of the center of gravity so that the pachinko machine 10 does not easily fall over due to vibration during transportation. In this case, since the launch control device 41 according to the present embodiment is configured to extend the shaft portions 28c and 28c in the vertical direction, when the pachinko machine 10 is placed horizontally, the launch control device 41 is provided. The device 41 is either suspended from the shafts 28c and 28c through the holes 45a and 45a or placed on the shafts 28c and 28c. Therefore, even when the engagement state between the hook member 47 and the lower end edge portion 19a of the mechanism set panel 19 is released due to vibration during transportation, the holes 45a and 45a with respect to the launch control device 41. Since the force that moves the launch control device 41 in the horizontal direction (above the pachinko machine 10) does not act on the shafts 28c, 28c from the bottom, the launch control device 41 falls off the inner frame 12 and is damaged. Is prevented. Furthermore, since the movement of the firing control device 41 is restricted by the hook member 47 and the protruding piece 46a as described above, it is possible to more reliably prevent the firing control device 41 from dropping and being damaged.

Further, when the pre-notated click member 47 is provided close to the hinge mechanism 36, even when a slight vibration occurs, a larger load on the hook member 47 by the principle of leverage since it takes, easily engagement of the lower edge portion 19a of the full-click member 47 and the mechanism set Release 19 is released. In contrast, in the present embodiment, the pre-notated click member 47, the upper surface 42b of the case body 42, the side (right side) of the forming side of the hinge mechanism 36 and the opposite side of the side portions ( It is formed close to the left side). That is, the release of the engagement between the lower edge portion 19a of the front notated click member 47 and the mechanism set plate 19, it is possible to reliably prevented.

  Next, a method for removing the launch control device 41 from the installation panel 28 (the middle frame 12) will be described. An operator puts his / her finger on the extending portion 49c of the hook member 47 formed on the launch control device 41 (case body 42), and moves the hook member 47 downward (in a direction close to the upper surface 42b of the case body 42). By being pushed down and elastically deformed, the engagement between the two 47 and 19 is released. In this state, the firing control device 41 is rotated in a direction away from the installation panel 28 via the hinge mechanism 36, and the firing control device 41 is further lifted upward to allow the shaft portion to pass through the holes 45a and 45a. By removing 28c, 28c, the launch control device 41 is detached from the installation panel 28 (inner frame 12). Here, since the extension part 49c is formed to extend to the rear of the mechanism set board 19, an operator can easily put his / her finger on the extension part 49c, and the launch control device 41 can be easily removed. That is, even if a problem occurs in the launch control device 41, the launch control device 41 can be easily replaced or maintained.

  By the way, as described above, the conventional pachinko machine covers the rear of the hitting ball driving unit 22 with a holding table and pivotally supports the launch control device 41 on the holding table. Therefore, when the hitting ball drive unit 22 has a problem and the replacement or maintenance work is performed, after the launch control device 41 is removed, the holding base must be further removed, and the work is complicated. On the other hand, in the pachinko machine 10 according to the embodiment, the rear side of the hitting ball driving unit 22 is directly covered by the launch control device 41, so that the hook member 47 and the lower edge 19a of the mechanism set board 19 are provided. It is possible to expose the hitting ball drive unit 22 simply by releasing the engagement with the release control device 41 and opening the launch control device 41 with respect to the installation board 28, and the replacement and maintenance work of the hit ball driving unit 22 is easy. The operation such as replacement can be simplified. Furthermore, by removing the launch control device 41 that is open with respect to the installation board 28, maintenance work and the like of the hitting ball drive unit 22 can be performed more easily.

  In the embodiment, when the hook member is formed on the upper surface of the firing control device and the hook member is engaged with the lower edge of the mechanism set panel, the firing control device is directed downward by the hook member. To prevent the shaft portion from coming out of the hole, but when a hook member is formed on the inner frame side and engaged with the first engagement portion formed in the firing control device, Even if the firing control device is urged downward, it is possible to restrict the shaft portion from coming off from the hole. Note that the shape and configuration of the first engagement portion formed on the launch control device side and the second engagement portion formed on the middle frame side are not limited to those of the embodiment, and various conventionally known types A member can be employed, and preferably, one of the first engaging portion and the second engaging portion may be formed by a hook member as described above. That is, the second engagement portion is not limited to the lower end edge portion of the mechanism set board, and a member that can be detachably engaged with the first engagement portion can be formed on the middle frame. Note that the gaming machine is not limited to a pachinko machine, and may be an arrangement ball machine or the like, and controls a hitting ball drive unit that launches a game ball toward the surface of the game board and the hitting ball drive unit. Any gaming machine provided with a launch control device can be used.
