An acceleration sensing device comprising an electrically conductive annular conductive support ring, an electrically conductive sphere to be placed on the upper inner periphery of said support ring, and an electrically conductive contact disposed in the neighborhood of said ball, thereby the device being capable of detecting acceleration in any direction by the use of the electrical conduction between the support ring and the contact through the ball.

Acceleration sensing device

A multi-stylus printing head cell in which a plurality of styli or electrodes are placed in and bonded to a plurality of parallel grooves formed in one of the major surfaces of a base in such a way that one end portions of the styli may extended out of the base; the exposed conductors of a flat flexible cable are overlaid upon the styli and made into electrical connection therewith; a retaining plate is placed over the exposed conductors; and the legs or side walls of a U-shaped holder are folded inwards over the retaining plate, whereby the base, the styli, the flat flexible cable, the retainer and the holder may be securely held as a unitary construction.
