Abstract: A photographic printing apparatus includes a reading device for reading image information from a film, and an exposure condition computing device for computing exposure conditions for exposing a photosensitive material based on the image information read by the reading device. The apparatus further includes an image information converter for converting the image information read by the reading device into image information expected to appear on the photosensitive material when the photosensitive material is exposed to the image information on the film under the exposure conditions computed by the exposure condition computing device. The image information converted by the image information converter is displayed on a monitor. The exposure condition computing device receives instructions through a control panel to correct the exposure conditions for the image information displayed on the monitor, or instructions not to correct the exposure conditions.

Abstract: In a drum brake, a wheel cylinder is located between a pair of adjacent shoe ends for a pair of brake shoes and a piston inserted into the wheel cylinder is slidably engaged through an anchor provided on a backing plate and further the piston is provided with a flange on the side thereof pressing a brake shoe so that the anchor is interposed between the flange of the piston and the wheel cylinder, and, furthermore, a strut is located between the other pair of adjacent shoe ends for the pair of the brake shoes in order to lighten a weight of the brake and facilitate a disassembly and assembly of the brake.
