イッチ入力信号として入力する入力回路からなることを
特徴とするスイッチ入力装置。Outputs a code signal corresponding to the combination of a plurality of switches arranged in parallel to generate electrical signals by opening and closing the contacts, and a switch whose operation is selected by the electrical signal from the switch, and the switch is operated. an encoder circuit that outputs a switch operation signal indicating that the switch has been activated; and an encoder circuit that outputs a switch operation signal indicating that the switch has been activated, and an operation signal that enables switch input with a delay of at least the amount of chuck generation time that occurs when the contact is opened or closed by the switch operation signal from the encoder circuit. A switch input device comprising: an actuation signal generating circuit that outputs an output; and an input circuit that inputs a code signal from an encoding circuit as a switch input signal only when the actuation signal is input.
