Abstract
An information output projection of a handy terminal is adapted to engage an information input hole of a data processing device. A light shutting out member is provided between an opening of the information input hole and an information receiving element in the data processing device. The light shutting out member is adapted to be opened by a depression force of the information output projection when the information output projection is inserted from the opening of the information input hole thereinto. Accordingly, malfunction of the device due to entry of optical noise from the opening of the information input hole is prevented.
