[0013]
9 is inserted into the insertion groove 21 of the rotary drum 4 in advance, and the mounting portion 3 ′ is sandwiched between a pair of opposing bullets 22. To do. And in a non-display state message board 3 is parallel to the vertical piece 6a of the substrate 6, as shown in Figure 7, it is one of the detection switch LS ₁ as shown in FIG. 7 turned OFF by the contact of the actuating cam 34 In this state, when the operation switch SW is closed, the relay R is activated so that one relay contact RA is switched from the switching contacts a, a ′ to b, b ′ and the other relay contact RB is switched to the switching contacts c, c. Since 'is switched to' d 'and' d ', respectively, an energization circuit of the switching contacts b and b', the detection switch LS ₂ , the driving motor 1 and the switching contacts d and d 'is formed, and the driving motor 1 rotates forward. By this rotation, the rotary drum 4 is also rotated forward via the gear transmission mechanism 2 so that the message board 3 is in a display state that is perpendicular to the vertical piece 6a from the non-display state parallel to the vertical piece 6a of the substrate 6, that is, FIG. The state indicated by the solid line Rotates in the state shown in Luo FIG phantom.
In the above description, when the driving motor 1 rotates, the end pieces 31a and 31b of the coil spring 31 are locked to the driving pin 33 and the driven pin 32 in a loaded state, so that the rotating drum 4 is integrated with the gear transmission mechanism 2. is rotated in the forward direction, since thereby actuating cam 34 away from one of the detection switches LS _1, the switch LS ₁ the detectable but it becomes ON, switching contact a, a 'and c, c' are both non-conductive state Therefore, the forward rotation of the drive motor 1 is maintained.
[0014]
Next, in the display state in which the rotating drum 4 is rotated 90 ° and the message board 3 protrudes at a right angle, the operation cam 34 contacts the other detection switch LS ₂ , so that the detection switch LS ₂ is turned OFF and is used for driving. When the energization circuit of the motor 1 is cut off, the rotation of the driving motor 1 stops and the state shown in FIG. 8 is obtained.
In the above, the drive motor 1 rotates by 90 degrees or more of the rotating drum 4 due to inertia, but the elastic torque transmitting mechanism 30 including the coil spring 31 is interposed between the terminal gear 20 of the gear transmitting mechanism 2 and the rotating drum 4. Therefore, the excessive rotation due to the inertia of the driving motor 1 is elastically absorbed by acting in the direction in which the both end pieces 31a and 31b of the coil spring 31 are separated, and the rotating drum 4 rotates 90 ° correctly. Since the message board 3 protrudes at a right angle, the display of the message board can be easily confirmed from the outside.
[0015]
When the operation switch SW is turned off from this state, the relay R is deactivated, the switching contacts b and b ′ of the relay contacts RA and RB and the contacts d and d ′ are turned off, and the switching of one relay contact RA is performed. The contact points a and a ′ and the switching contacts c and c ′ of the other relay contact RB are turned on, and the energization circuit of the switching contacts a and a ′, the detection switch LS ₁ , the drive motor 1 and the switching contacts c and c ′. Thus, the drive motor 1 rotates in the reverse direction, and the rotation causes the message board 3 together with the rotating drum 4 to return from the display state to the non-display state, and the operating cam 34 contacts the detection switch LS ₁ to detection switch LS ₁ is turned OFF, the rotation of the driving motor 1 is stopped.
Also in this case, the excessive rotation of the drive motor 1 is absorbed by the coil spring 31 by the elastic torque transmission mechanism 30. Further by rotation of the drive motor 1, the actuating cam 34 is away from the other detection switch LS _2, the detection switch LS ₂ is restored to ON, the state shown in Figure 7.
[0016]
In the above description, when an external force is applied to the message board 3 in the non-display state or in the display state and the rotating drum 4 rotates from the non-cover state to the display state or from the display state to the non-display state, the rotational force is Since the terminal gear 20 is in a fixed state by meshing with the gear transmission mechanism 2, particularly the worm 16 and the worm wheel 18, the terminal gear 20 is absorbed by the coil spring 31 interposed between the rotary drum 4 and the terminal gear 20, and has a buffering action. can get.
Note the rotary drum 4 by the action of an external force to rotate, which an integral operation cam 34, since the motor 1 is made energized away from the detection switch LS ₁ to LS ₂ to the drive motor 1 is overloaded In this overload state, the overload prevention circuit S operates and the drive motor 1 is de-energized.
[0017]
In the above embodiment, the case where the operation cam 34 is integrally attached to the rotating drum 4 is illustrated, but FIGS. 10 to 13 are operated via the sleeve 40 on the terminal gear 20 of the gear transmission mechanism 2 instead of the rotating drum 4. Another embodiment in which the cam 34 is provided integrally is shown, and there is no substantial difference from the previous embodiment in the remaining configuration.
[0018]
In this configuration, when the operation switch SW is closed from the non-display state of the message board, the drive motor 1 rotates in the forward direction as described above, whereby the rotary drum 4 also rotates in the forward direction and the message board 3 is displayed. When the operation switch SW is turned off from this state, the drive motor 1 is reversely rotated, whereby the rotating drum 4 is also reversely rotated to restore the message board to the non-display state. There is no substantial difference from the example.
[0019]
In this configuration, external force F acts on the message board 3 in the non-display state or in the display state, and the rotating drum 4 moves from the non-display state to the display state as shown by the phantom lines in FIG. When rotating in the direction of the non-covered state from the display state indicated by the phantom line, the rotational force is such that the terminal gear 20 is in a fixed state due to the engagement of the gear transmission mechanism 2, particularly the worm 16 and the worm wheel 18. And the operating cam 34 is not likely to be separated from the detection switches LS _{1 to} LS _{2. In} this embodiment, the control circuit 34 is overloaded. The prevention circuit S can be omitted.
[0020]
In the above embodiment, the operation switch is turned on and off from a remote position so that the required display can be made. However, the operation switch is turned on by an electric signal generated when the game machine is in a specific state (for example, a big hit). The display may be turned on and off.
[0021]
