Title:
MOBILE TYPE OPERATING MACHINE
Document Type and Number:
Japanese Patent JPS6394310
Kind Code:
A
Abstract:
PURPOSE:To prevent an operating machine main body without constantly directing an originating device to the operating machine and to improve the safety of an operation by remotely operating a mobile type operating machine by an optical signal. CONSTITUTION:The operating machine receives the optical signal from a remote operating part 18 to travel and a receiver 12 receiving this optical signal is disposed in the operating machine. In the receiver 12, photodiodes 14, 15 are disposed and when the optical signal of a prescribed wavelength is received, the signal is supplied to a controller 16. In the remove operating part 18, the originating device 20 for an information signal and the originating device 21 for a holding signal are incorporated and the optical signal is generated according to respective operating switches disposed on the operating part 18 from the originating device 20. Then, the light emitting direction thereof is limited by the irradiation port 18A of the operating part 18 to provide a directivity. Accordingly, the optical signal is not transmitted without directing the irradiation port 18A to the direction of the receiver 12, nor the operating machine is operated.
