Abstract
PURPOSE: To eliminate a troublesome operation of a setting key and also to prevent occurrence of an erroneous setting by a system wherein a preset memory is provided and the value is transmitted to a subtraction counter through an existing key operation.
CONSTITUTION: An hour data set in a display memory DM with a setting means S is set to a subtraction counter SC by way of AND gate circuit A3 by actuating a start/stop key SS. When the hour data is not stored in a preset memory PM, the status is detected with a zero detecting means ZD, a circuit A2 is activated, therefore the hour data of the key SS can be set in the memory PM. Where the data is stored in the memory PM and a change is not required, a transmission to the memory PM is blocked by the circuit A2. Then, where a value of the memory PM is changed, the data can be changed by storing the hour data of the subtraction counter SC to the memory PM through erasing it with an erase key K. Then, after actuating the key K to set to the display memory DM, a data transmitting key IK is actuated so that the hour data of the memory PM will be stored in the sounding memory M by way of a circuit A5.
