Title: Key driving device
Inventor: MURATA YOSHIYUKI
IPC: G10F1/02
Filed: 1990-06-26
Abstract: PURPOSE:To speed up both key pushing operation and key detaching operation by providing a key driving means which drives the front end part of a key so as to operate and repulse it, and simultaneously, attracts and drives a second electromagnet means, and drives the rear end part of the key so as to operate and attract it by this. CONSTITUTION:The key driving means 10 which drives the front end part side of the key 1 so as to operate and repulse it, and simultaneously, attracts and drives the second electromagnet means 15, and drives the rear part side of the key 1 so as to operate and attract it by this is provided. Then, at the time of driving the key 1 to a key pushing direction or a key detaching direction, a first and a second electromagnets 14, 15 installed at the front end part and the rear end part of the key 1 (or front end part and its opposite part of key) are excited so that attractive force and repulsive force are generated simultaneously at one side and the other side respectively. Accordingly, the force in a rotating direction due to the repulsive force is added to the force in the rotating direction of the key 1 due to the attractive force. Therefore, the key 1 comes to be rotated by the larger force compared with a case that it is driven by only the attractive force (or repulsive force). Thus, the speedup of both the key pushing operation and the key detaching operation can be attained.
