<p>PURPOSE:To omit a detecting switch, and to make the titled device small in size and low in cost by providing a motor for driving to rotate a rotating body, and a control means for controlling an operating state of the device in accordance with an output of an encoder. CONSTITUTION:An encoder of a magnetic pulse reading system for executing read by a magnetic detecting element which is attached to a fixed part of a motor 1 is attached to the titled device, therefore, an encoder output corresponding to a rotational phase or the motor 1 is generated. Also, a cam disk 2 and the motor 1 rotate as one body, therefore, a rotational phase of the cam disk 2 becomes the same as the rotational phase of the motor 1. Accordingly, the rotational phase of the cam disk 2 can be derived exactly by a control device 4.</p> |
