DRIVING GEAR OF BODY BY MOTOR

摘要

PURPOSE: To stop a driven body by an electric motor repeatedly and with a high reliability at a predetermined position without applying an excessive voltage by providing an initializing means to a particular power supply phase to the motor switched by the operation of more than one switch related to mechanical displacement measuring means. CONSTITUTION: A blind is made as a cassette type, is housed in a box construction body 12 fixed to a reveal 13, and a roller shutter is wound around a pipe- shaped motor 4 inside a roller pipe 3. And the motor 4 and a counting device 5 are made in one united body and is driven with the motor 4. And a calculating device 5 memorizes the stop position of the blind and is set so as to operate a reverse rotation switch before a predetermined time when a partition profile portion 14 comes to the boundary above the box structural body 12 and also memorizes the stop position of the portion where the blind is not wound and the switch of the calculating device 5 is operated when he blind is at a non-wind position requested.
