<p>PURPOSE:To eliminate the need for much space and to provide an inexpensive voice output function by providing a voice output means common to a plurality of devices and by controlling the switching of voice output means by using a control means. CONSTITUTION:CPU 3a, a voice synthesizing device 3e, a buzzer output device 3f, and relay output device 3g are arranged as a controller 3. When the entrance judgment result obtained by using a card reader 1A is OK, lock is released by the controller 3 to which a signal is inputted. When the result is N.G., the CPU 3a controls the relay output device 3g to close a contact 1A, so that the voice synthesizing device 3e announces the request for re-read via a speaker 4Aa. At this time, judgment is made by an adjacent card reader 1B. If a contact 1B is closed by N.G., a buzzer 4B sounds in place of announcement. Thus, by using the common voice synthesizing device 3e, the voice by one card reader can be replaced by buzzer when the other card reader is operating.</p> |
