Abstract
Abstract In an input device, a scanning pulse is supplied in time division fashion to a plurality of switching means effecting information input indications. The scanning pulse applied to the driven switching means is detected by a probe to stop the operation of address means which varies its contents in accordance with the scanning pulse. The content of the address means during the stoppage thereof are indicated as input information on the driven switching means.
