Abstract
A plurality of ON-OFF switch type operating keys are connected through respective 'AND' gates to an encoder which delivers coded signals as predetermined by the operated keys to a micro-computer where a cooking program is instituted. A switch connected to the control inputs of the 'AND' gates is closed to disable the outputs from the operated keys. Alternatively the keys may be arranged in a matrix and connected to an encoder. The keys are scanned with scan signals applied to the matrix from the micro-computer through the normally closed contact of a switch. The switch may be opened to disable the outputs from the operated keys. A cooking range is controlled in accordance with the cooking program.
