<p>PURPOSE:To improve operability at the time of a manual handling with a constantly positive key input ensured by arranging a solid-state member, mechanically supporting a pair of electrodes, on the back surface of the pair of electrodes constituting a keyboard. CONSTITUTION:The pressing operation of a key top 3a of a keyboard part causes a conductor 5 to be projected having slight roundness to a pair of electrodes 7a and 7b sides according to the bending of the key top 3a. At that time, the downward bending of the pair of 7a and 7b can be prevented and a closed circuit actuation ensured with the resistance to the conductor 5 arisen with a solid-state member 13 arranged on the back surface of the electrodes 7a and 7b or a thin type battery 9 functioning as the solidstate member.</p> |
