Abstract
PURPOSE: To make a simple and small construction having a reduced number of counters by generating touch data upon the start and end of key depression in accordance with the recorded content difference of the counted values of the counters.
CONSTITUTION: When the key code of a key, which is started to be depressed, is fed from a switch group 10, the counted value of the counter for counting a preset clock of a key logic 20 is stored in the data memory 32 of a logic 30 which is under an offering condition with the reguest code from the logic 20. In accordance with the change in the request code of the logic 20 in response to the end of the key depression, the logic 30 stores in the memory 32 the counted value of the counter of the logic so that the differentiation of the both stored contents, which are stored in the memory 32, is performed in accordance with the program of the memory 32 through a central operation controller 31 thereby to generate the touch response data. As a result, the construction is made so simple and small that one counter is provided while dispensing with the counter for each cannel.
