Abstract: A vehicle disc brake includes pad retainers. Each pad retainer includes: a pair of retainer portions; a connecting piece connecting the pair of retainer portions together; and pad returning portions. The retainer portion includes: an inner piece; an outer piece; and a deep side piece which is laid on the opposing surface so as to connect the outer piece and the inner piece together. The pad returning portion is formed by inclining a distal end portion of a narrow elongated piece while causing the distal end portion to warp into a curved shape. A dislodgement preventing projecting portion is formed through pressing on at least one of the outer piece and the inner piece so as to project towards an interior of a pad guide groove so that the lug piece can ride thereover when the lug piece is inserted into the pad guide groove.

Abstract: A presensitized offset printing plate is identified by its reflected light as one of the known presensitized plates of different light reflective characteristics. White light is casted on a freshly introduced presensitized plate to be tested so as to measure the intensity of the reflected light from the surface of the photosensitive layer thereon in four color signals, which are a magenta signal, yellow signal, cyan signal and black-and-white signal. Then the reflected light is compared in each color signal with the reference data which are inherently determined with respect to known presensitized plates of different light reflective characteristics, whereby the tested presensitized plate is recognized or identified as one of the known presensitized plates. Said reference data, which are different with respect to the known plates, are stored in memory means.
