ちながら繰返し動作を行なう。 Conventionally, this type of device has 24 units as shown in Figure 1.
For example, by combining a single-pole double-throw mechanism changeover switch 1 that outputs a switching signal using a time-synchronized time switch or the like, and a single-pole double-throw microswitch 3 that controls the intermittent drive of a synchronous motor 2, the changeover switch 1 is switched to the terminal 103, an electric circuit is formed, a voltage is applied to the synchronous motor 2, it starts rotating, and a special cam A4 fixed to the output shaft of the synchronous motor 2 connects the micro switch 3 to the terminal 302. Rotate until it switches to the side. During this rotation, a special cam B5 (not shown) serving as a driven portion controls a switch and outputs a pulse. In addition, in the next operation, when the changeover switch 1 is switched to the terminal 102 side, an electric circuit is formed and a voltage is applied to the synchronous motor 2, which starts rotating and uses the special cam A4 to switch the microswitch 3 to the terminal 303 side. Rotate until it switches to . Each time the switch 1 performs such a switching operation, the operation is repeated while maintaining the relationship with the contacts of the microswitch 3.

生することが出来なくなることがあつた。 However, when this micro switch 3 is used, the switching lever 6 that pushes up the plunger 11 of the micro switch 3 is pushed up in the direction of arrow B by the inclined surface 401 of the special cam A4, as shown in FIG. 3 is terminal 30
At the same time as switching to the terminal 303 side, the electric circuit is cut off and the synchronous motor 2 stops rotating in the direction of the arrow A, and the micro switch 3 is switched to the terminal 303 side without overtravel. After stopping, the synchronous motor 2 rotates slightly in the opposite direction of arrow A due to play in the reduction gear within the synchronous motor 2, and the special cam A4 is shifted by θ 1 ° from the switching position of the micro switch 3. Due to the spring force of the built-in spring (not shown) in the plunger 11 of No. 3, the plunger 11 returns in the direction of arrow C, resulting in unstable contact on the terminal 303 side or failure to contact either the terminal 303 side or the terminal 302 side. Furthermore, even if the switch 1 was switched, no voltage was applied to the synchronous motor 2, making it unable to rotate and generating pulses.

い。 In addition, when the special cam A4 further rotates in the direction of arrow A and the roller 7 of the switching lever 6 falls into the recess 402 of the special cam A4 as a reverse operation, this recess 402 prevents the reverse rotation in the opposite direction of arrow A. Therefore, the contact state of the micro switch 3 to the terminal 302 side is perfect, and the above-mentioned problem does not occur.

変化しない。 To explain the operation using this configuration and circuit, when the switch 1 is switched to the terminal 103 side, the AC power supply 12 is connected to the terminals 202 and 203 of the synchronous motor 2.
terminal 101 of switch 1 - terminal 103 of switch 1 - terminal 303, 303A of micro switch 3, 3A - terminal 301, 301A of micro switch 3, 3A
The synchronous motor 2 starts rotating in the direction of the arrow A, and rotates until the roller 7 of the switching lever 6 falls into the recess 402 of the special cam 4. At the same time, the microswitches 3 and 3A close the terminal 301.
-terminal 302, terminal 301A-terminal 302A side, resulting in the switching state shown by the broken line in FIG. 3, and the power supply from the power supply 12 to the synchronous motor 2 is cut off and stopped. After the rotation of synchronous motor 2 has stopped,
The above-mentioned reverse rotation of the output shaft 201 cannot be performed because the roller 7 has fallen into the recess 402 of the special cam A4, and the switching states of the micro switches 3 and 3A do not change.

ている。 Next, when the switch 1 is switched to the terminal 102 side, the AC power supply 1 is connected to the terminals 202 and 203 of the synchronous motor 2.
2 is the terminal 101 of switch 1 - the terminal 102 of switch 1 - the terminal 30 of micro switch 3, 3A
2,302A-A voltage is applied through the terminals 301, 301A of the micro switches 3, 3A, the synchronous motor 2 starts rotating in the direction of arrow A, the roller 7 of the switching lever 6 is pushed up from the recess 402 of the special cam 4, and Pushed up by the inclined surface 401, the plunger 11 of the micro switch 3 switches to the terminal 301-terminal 303 at position D shown in FIG. Since the power supply 12 is applied to the synchronous motor 2, it continues to rotate by an angle of θ 1 ° + α, and the plunger 11A of the micro switch 3A
is switched from terminal 301A to terminal 303A, and the application of power supply 12 to synchronous motor 2 is cut off and stopped. After the rotation of the synchronous motor 2 has stopped, the above-mentioned reversal angle Q1° of the output shaft 201 differs from the operating position of the micro switches 3, 3A on the inclined surface 401 of the special cam A4 by ΔS [the rotation angle of the special cam A4] difference,
In other words, since the deviation angle Q1゜+α] of the synchronous motor 2 is provided, the terminal 30 of the micro switch 3A
Even if the contact state of 1A-terminal 303A becomes unstable, the terminal 301-terminal 30 of micro switch 3
Since the contact state of switch 3 is a complete contact state with an overtravel smaller than △S, next switch 1
The terminal waits until terminal 101-terminal 103 is switched.

ものにはすべて適用できるものである。 During the rotation of the synchronous motor 2, a pulse sending switch (not shown) is controlled by the protrusion 501 of the special cam B5. Although the above example has shown the application of this invention to a pulse generator,
This invention can be applied to any device that drives a driven part by a certain amount in response to a switching signal.

組替えせずに調整使用出来る。 As described above, since the present invention controls the rotation of the synchronous motor 2 by alternately combining the switching of the switch 1 and the micro switches 3 and 3A, the switching state of the micro switch due to reversal of the synchronous motor is different from the conventional one. Even if the motor becomes unstable, one microswitch always maintains a complete switching state, and the phenomenon in which the synchronous motor becomes unable to rotate is prevented. In addition, since the pressing amount of the microswitches 3 and 3A can be easily changed using the adjustment screw, by feeding the adjustment screw in consideration of the amount of reversal due to the difference in the characteristics of the synchronous motor, it is possible to rearrange the synchronous motor, which could not be incorporated in the past. It can be used without any adjustment.
