In addition, the gap formed between the operation base 51 and the base lid portion 31 is set to be bent along the radial direction of the unit base 24, and the operation base 51 and the contact region forming portion 39 are slightly spaced ( For example, they are sufficiently close (or abutted) with a gap sufficiently narrower than the thickness of a one-yen coin). Further, the sliding portion 87 abuts against the convex portion 86 while being urged by the urging member 90, the guide pin 76 is fitted into the guide groove 77, and the other end portion 25b of the rotating shaft 25 is on the frame side. It protrudes from the bearing portion 36b.

  At this time, since the fitting preventing portion 81 is provided on the base lid portion 31 at a location off the guide groove 77 on the concentric circle of the guide groove 77, the guide groove 77 is temporarily removed from the extension line of the guide pin 76. When the rotation support portion 38 and the rotation fitting space portion 55 are brought close to each other in the state where the guide pin 76 is brought into contact, the guide pin 76 contacts the fitting prevention portion 81. As a result, the locking boss 56 and the operation-side bearing portion 36a are prevented from coming into contact with each other, and the thickness of the one-yen coin is larger between the rear end portion of the operation base portion 51 and the front edge portion of the contact region forming portion 39. Create a sufficiently wide gap. Further, the rotation support portion 38 cannot be sufficiently fitted into the rotation fitting space portion 55, and the sliding portion 87 is prevented from coming into contact with the convex portion 86. Accordingly, it is possible to prevent the inconvenience of assembling the firing operation unit 17 in a state where the guide pin 76 is detached from the guide groove 77.

  When the rotation shaft 25 is inserted into the unit base 24 and the rotation operation unit 26 is assembled, the stopper 61 is attached to the other end 25b of the rotation shaft 25 and the flange 63 is brought into contact with the frame side bearing portion 36b. In this state, the stopper 61 is fixed by the fixing member 62. Then, the movement of the rotation shaft 25 and the rotation operation unit 26 in the direction away from the unit base 24 (the direction of dropping) is restricted and the rattling along the axial direction of the rotation shaft 25 is prevented. The Further, the posture setting biasing member 67 is locked between the stopper side biasing lock receiving portion 68 and the base side biasing lock receiving portion 69, and the firing operation unit 17 is assembled. Then, the assembled launching operation unit 17 rotates the rotation operation unit 26, the rotation shaft 25, and the stopper 61 in the initial state return direction A by the urging force of the posture setting urging member 67, and the guide pin 76 is moved. The rotation operation unit 26 is maintained in the rotation start posture by contacting the start end side contact wall 78.

  Further, in order to attach the firing operation unit 17 to the front frame 3, the stop signal wiring and the touch detection signal wiring are passed through a wiring opening (not shown) provided in the unit fixing part 15, and the firing operation unit 17 17 is set to a posture in which the connecting portion 65 faces the unit fixing portion 15 side. Then, in this posture, the unit base 24 is inserted into the unit fixing portion 15, and the positioning pin 30 is fitted into the positioning recess 21. Then, the wiring lead-out portion 48 is covered with the unit fixing portion 15 (see FIG. 2A), and the connecting portion 65 passes through the connecting opening 20 and is in the normal state (that is, the initial state where it is not rotated). As a result, the rotation operation unit 26 and the connection receiving unit 19 can rotate together. At this time, the posture (phase) of the connecting portion 65 can be maintained in a state in which the turning operation portion 26 assumes the turning start posture by the biasing force of the posture setting biasing member 67. The inconvenience that the part 65 rotates carelessly can be eliminated, and the connecting part 65 can be easily engaged with the connection receiving part 19. Then, when the connecting portion 65 is engaged with the connecting receiving portion 19 and the firing operation unit 17 is sufficiently pushed into the unit fixing portion 15, a screw or the like is provided from the back side of the lower plate unit 13 (the back side of the front frame 3). The fastening base (not shown) is inserted, the unit base 24 and the unit fastening portion 15 are fastened to fix the firing operation unit 17, and the stop signal wiring and touch detection signal wiring are connected to the front frame 3 side. Connect to a connector (not shown).

  The firing operation unit 17 mounted on the front frame 3 in this way covers the engaging portion between the rotation shaft 25 and the rotation operation unit 26 with the unit base 24, and the stopper 61 covers the front frame 3 and the unit base 24. And cover with. Therefore, it is possible to avoid the engagement portion between the rotation shaft 25 and the rotation operation unit 26 and the engagement portion between the rotation shaft 25 and the unit base 24 from being exposed, and the launch operation unit 17 is illegally disassembled. Can be prevented. Further, it is difficult to impair the design of the launch operation unit 17. Furthermore, since the connecting portion 65 is provided in the stopper 61, there is no need to separately provide a member for engaging the rotating shaft 25 and the unit base 24 and a member for connecting the rotating shaft 25 and the launching device 18. The number of parts constituting the launch operation unit 17 can be reduced.

  In order to operate the launch operation unit 17 to launch a game ball, first, the launch operation unit 17 is grasped by hand from the rotation operation unit 26 side, and a finger is engaged with the engagement protrusion of the rotation operation unit 26. 53, and the fingertip abuts against the contact region forming portion 39. In this state, the rotation operation portion 26 is applied to the biasing force of the posture setting biasing member 67 and the biasing force of the launching side biasing member of the launching device 18. Against this, it rotates in the direction B for adjusting the firing force. Then, the rotational force of the rotation operation unit 26 is transmitted to the connection receiving unit 19 via the rotation shaft 25, the stopper 61, and the connection unit 65, and the connection reception unit 19 rotates together with the rotation operation unit 26. Further, the operation of the stop switch 43 is released, and the launching operation in the launching device 18 is started. Then, when the rotation operation unit 26 is continuously rotated in the firing force increase adjustment direction B, the connection receiving unit 19 continues to rotate and the firing force of the firing device 18 is gradually set stronger.

  At this time, since the firing operation unit 17 includes the guide mechanism 75, the rotation operation unit 26 can be operated smoothly. Further, when the rotation operation unit 26 is rotated, the vibration generating mechanism 85 slides the sliding part 87 on the convex part 86, and the sliding part 87 gets over the convex part 86a and is adjacent to the convex part 86a. Whenever it fits in between, the sliding part 87 and the convex part 86a collide, and a vibration and a collision sound are generated. Therefore, the player can grasp that the rotation operation unit 26 has moved by feeling vibration with the hand operating the firing operation unit 17 or listening to the collision sound with the ear. Thereby, it is possible to obtain an indication as to whether or not the rotation operation unit 26 is maintained at a certain position, and it becomes easy to continuously set the desired launching force of the game ball. Further, a gap with a dimension sufficiently narrower than the thickness of a one-yen coin is formed between the unit base 24 and the rotation operation unit 26, and the outside of the firing operation unit 17 is formed in the gap. Since the depth of the portion exposed to (i.e., the separation distance d between the rotation support portion 38 and the contact region forming portion 39) is set to be smaller than the radius of the one-yen coin, the player holds the coin in this gap. Therefore, it is difficult to maintain the rotation position of the rotation operation unit 26. Therefore, it becomes easy to prevent the player from attempting to play a game while keeping the firing force of the game ball in a constant state without touching the firing operation unit 17, and the player can be encouraged to execute a healthy game.

  By the way, in the above embodiment, the guide pin 76 of the guide mechanism 75 is provided on the rotation operation unit 26 side, and the guide groove 77 is provided on the unit base 24 side. However, the present invention is not limited to this, and the guide pin is a unit. It may be provided on the base 24 side and the guide groove may be provided on the rotation operation unit 26 side. Further, although the sliding portion 87 of the vibration generating mechanism 85 is provided on the rotating operation portion 26 side and the protruding portion 86 is provided on the unit base 24 side, the present invention is not limited to this. In short, it is only necessary that the sliding portion 87 can slide on the convex portion 86 as the rotational operation portion 26 rotates. For example, a convex portion is provided on the unit base 24 and slides on the rotational operation portion 26. You may provide a part in the state which can be rotated together.

  Furthermore, in the said embodiment, although the rotation operation part 26 was comprised by the some structural member (the operation base 51, the decoration member 52), this invention is not limited to this, The rotation operation part 26 is one structural member. You may comprise. In the above embodiment, a gap having a dimension sufficiently narrower than the thickness of a one-yen coin is bent between the unit base 24 and the rotation operation unit 26, and the firing operation unit is included in the gap. Although the depth of the portion exposed to the outside of 17 is set to a size smaller than the radius of the 1-yen coin, the present invention is not limited to this, and the standard of the size of the gap is another coin (10-yen coin or 100-yen coin). You may set with the thickness and radius of a coin. That is, a gap having a dimension sufficiently narrower than the thickness of a coin other than a 1-yen coin (for example, a 10-yen coin or a 100-yen coin) is formed between the unit base 24 and the rotation operation unit 26 in a bent state. And the depth of the part exposed outside the firing operation unit 17 in the gap may be smaller than the radius of a coin other than a 1-yen coin (for example, a 10-yen coin or a 100-yen coin).

  And although the launch operation unit 17 of the said embodiment was comprised so that the turning power of the rotation operation part 26 might be directly transmitted to the launch device 18, and the launch device 18 was operated, this invention is not limited to this. For example, a variable resistor capable of outputting an adjustment signal is built in the launch operation unit, and the adjustment signal (specifically variable) is adjusted by rotating the adjustment rotation shaft of the variable resistor by the rotational force of the rotation operation unit 26. The resistance value of the resistor may be changed, and the firing force of the launching device may be set based on the adjustment signal.

  Further, in the above embodiment, a pachinko gaming machine which is a typical gaming machine has been described as an example, but the present invention is not limited thereto, and a launch operation unit for performing a launch operation of a game ball is provided on the front frame. Any gaming machine may be used as long as it is equipped.
