Input pen for input device of character or the like

Abstract

Abstract PURPOSE:To extend a life of an input pen, by constituting so that reaction force in case when the first coil spring is compressed through a pen point becomes larger than resultant force which is obtained by adding reaction force of the second coil spring and magnetic adsorption force of a permanent magnet and a magnet plate, and inputting a character, etc. CONSTITUTION:When the tip part of a pen point 17 is pushed in, a coil spring 23 is compressed, and when its reaction force becomes stronger than resultant force of magnetic force for adsorbing a magnet 22 to a magnetic plate 15, and reaction force of a coil spring 24, the magnet 22 is detached from the magnetic plate 15, and the spring 24 is compressed. As a result, the magnet 22 is detached from the pen point 17, and a coil 18 which is circuit-connected through the pen point 17, and the magnet 22 are disconnected, therefore, a resonance point of an LC circuit constituted of a capacitor 16 and the coil 18 is shifted from that which is in a static state, and display information of an input plate is inputted.
