Abstract

PURPOSE: To highly precisely stop a rotary body at a prescribed position by converting the rotary motion of a rotary solenoid into a straight-line motion and using the engagement of a contact pin and the notch part of a cam disk. CONSTITUTION: When the command signal of rotary stoppage is inputted to the rotary solenoid 5, the cam disk 1 stops as follows. When the rotary solenoid 5 becomes an off-state, a guide pin 9 slightly moves to a left direction. Then, the contact pin 6 slightly moves to the left direction by the pin 9. Thus, the contact pin 6 is brought into contact with the peripheral part of the cam disk 1 and it continues rotation for a while. Then, the pin 6 drops into the notch part 1A. A lower end part 9A release the contactor 10A of a microswitch 10 by the movement of a sliding plate 9 in the left direction, and the microswitch 10 is turned off. Then, an antenna rotary plate is precisely stopped.
