Title:
STARTER OF AUTOMATIC DOOR
Document Type and Number:
Japanese Patent JP2636102
Kind Code:
B2
Abstract:
PURPOSE: To enable a control machine for opening or closing a door to be driven by fixing a light emitting element of a sub machine and a light receiving element of a main machine to an opposed position and operating a starting switch of the sub machine.
CONSTITUTION: A main machine 4 and a sub machine 3 are set up in a position where they are opposed to each other at both sides of an all glass door 1 which is opened or closed by means of a door engine. When a starting switch of the sub machine 3 is operated, a light emitting element D1 emits its light and a light receiving element D2 of the main machine 4 receives this light, a transistor T of a photostarting circuit 41 becomes a state of being conducted, transmitting a receiving signal P to a microcomputer 42, and thereby a program is started. Then, a light signal is transmitted to a light receiving element D4 in a door engine case from a light emitting element D3 of a transmitting part 43, thus a door starting motor is driven by a control machine 6.
