ABSTRACT:
A control cam plate having a periphery divided into four sections of different radiuses is driven to rotate by a cam motor mounted on a supporting table. The supporting table is rotatably secured in a microwave oven, and one end of the supporting table is fixed to a manually operable selection lever for shifting the location of the control cam plate. A switching means is associated with the control cam plate for controlling a repetition rate of a power supply to a magnetron employed in the microwave oven in response to slide operation of the manually operable selection lever. In a preferred form, a menu drum is provided in such a manner as to rotate in response to the slide operation of the manually operable selection lever, thereby facilitating recognition of cooking modes.
