Abstract

A steel blade I is used to transfer a contact point 2. The blade is held between friction shoes 3-3 mounted on stationary frame 4 and between friction shoes 5 and 6 mounted on a reciprocating frame 7. The friction shoe 6 is made of a semiconductive rubber having an electrostatic adhesive effect when a voltage is applied. The blade 1 is normally held in a fixed position by the friction produced by shoes 3-3 which exceeds the normal friction produced by shoes 5 and 6.

Storage Device

A steel blade I is used to transfer a contact point 2. The blade is held between friction shoes 3-3 mounted on stationary frame 4 and between friction shoes 5 and 6 mounted on a reciprocating frame 7. The friction shoe 6 is made of a semiconductive rubber having an electrostatic adhesive effect when a voltage is applied. The blade 1 is normally held in a fixed position by the friction produced by shoes 3-3 which exceeds the normal friction produced by shoes 5 and 6.

If a code bit is to be stored, a voltage of short duration is applied between the blade 1 and the shoe 6 at a time when the frame 7 is moving downward. As a result of the application of this voltage, an adhesive effect is created between blade 1 and shoe 6 and the friction between the blade 1 and shoes 5 and 6 exceeds that between the blade 1 and the shoes 3-3 and the blade 1 moves with frame 7. The blade 1 remains displaced, being held by the friction shoes 3-3 until reset by the upward motion of the reset plate 8.
