PURPOSE:To obtain an electronic equipment containing an operating mode switchable switch with which a user can easily confirm the operating mode of the switch and also can prevent the misoperation. CONSTITUTION:When the state of a multi-type switch group 1 is changed, a gate array 2 generates an interruption to a one-chip microcomputer 3-1 and also writes the interruption factor. When the interruption factor is confirmed, the microcomputer 3-1 inquires the array 2 about the presence or absence of a push-button switch. If the presence of the push-button switch is confirmed, a timer is started to generate a sound of the tone quality accordant with the operating mode of the button switch. Then the operating mode of the switch is carried out when the timer decides that the operation of the push-button switch is carried on for a fixed time. Thus a user can recognize the operating mode from the tone quality. |
