Abstract

PURPOSE: To ensure an easy operation by detecting the fact that the data output has received at CPU without fail after confirmation of the operation of the key switch via the display unit.
CONSTITUTION: The data output corresponding to the item is sent to CPU in accordance with the key operation of item input key switch 51. At the same time, the strobe signal is transmitted to CPU, and the fact that the data has been delivered assuredly through display unit 59 is confirmed. Receiving the data output and the strobe signal, CPU produces the monitor signal. Then the book identification signal and the page identification signal are transmitted to CPU via multiplexer 56 and in accordance with the monitor signal, and at the same time buzzer 60 is actuated. Thus, the operator knows that the key switch is operated and that the data output is received at CPU assuredly to ensure easy operation.
