In the parallel type information input device having this cable, serial data is output from the main body of the information input device, so that the cable can have only one data transmission core wire.

Further, in the parallel type information input device having the light emitting means, since the optical signal obtained by converting the serial data is output from the information input device main body, no cable is required, so the cable becomes an obstacle during the operation. It does not entangle or get entangled.
