OPERATION RESPONSE CONTROL MECHANISM

PURPOSE:To provide an operation response control mechanism capable of quickly informing an operation response to an operator in accordance with the operation of an input device. CONSTITUTION:This operation response control mechanism is provided with an input device control mechanism 3 for receiving input coordinate data from a touch panel, an operation response permitting mechanism 5 having a table indicating the validity/invalidity of input coordinate data, a comparing part 4, and a response signal generating part 6. The comparing part 4 compares input coordinate data with the contents of the table included in the mechanism 5, and when the input coordinate data are valid as the result of comparison, drives the generating part 6 to execute an operation response by means of changes in voice, lamps and touch symbols for the touch panel.
