PURPOSE:To make it possible to easily and reliably finish the reserving operations of a program timer by flashing a lamp corresponding to a reserving program button in case the reserving operations are insufficient. CONSTITUTION:In case a reservation finishing button 11 is depressed while depressing a time input button 114 but not a channel input button 115, the content of a first time memory 131 is changed from the condition ''A'', under which no time and channel are reserved, to the condition ''T1'' under which they are reserved. However, the content of a first channel memory 132 is left under the condition ''A'' because there is no input. As a result, a memory content judging unit 126 feeds ''1'' to an OR circuit 1200 to operate a counter 142. This counter 142 counts a preset number of the pulses from the clock circuit 141 thereby to change the output levels from ''1'' to ''0'' and ''0'' to ''1'' upon each counting operation. These outputs are fed to the first program lamp, which is flashed so that the operation insufficiency can be recognized. |
