Abstract: A camera with a built-in mask comprising a mask that is mounted on the optical axis between an imaging lens and the plane of a film, whereby photographing is performed by light cutting or light filtering the mask image of a pattern or a symbol in a manner that the image of an object is partially converted with the mask image.

Abstract: A braille printer that embosses braille characters line by line, in which embossing dies formed in the form of a line on which a plurality of projections or recesses for embossing braille characters, and debossing dies, on which a plurality of projections or recesses are formed in a line, are made to face each other, and the recesses and projections at positions corresponding to printing signals are pressed against each other. Cams for making the embossing dies move forward are disposed at both end positions of a line of characters below each of the embossing dies which are held at embossing positions in such a manner as to be movable forward or backward. The contour of each of these cams at both end positions of the line of characters have an apex, each of these apices being the same distance from a cam shaft.

Abstract: A braille printer that embosses braille characters by a method wherein a paper feed mechanism using a motor is disposed in the entry of a paper feed passage, a motor controler for feeding paper on which braille characters are embossed to an emboss start position according to one dot line spacing and character line spacing is mounted thereto, and the projections and recesses of both the dies at positions corresponding to the braille signals at an embossing position in the midway of the paper feed passage, wherein there are disposed a lead-edge position sensor for detecting the lead-edge position of paper is disposed in the paper-feed passage, and an obverse-/reverse-surface indicator for outputting an obverse-/reverse-surface indication signal indicating which one of either or the obverse surface or reverse surface of the paper should be printed, and an initial paper-feed controller for, in response to a detection signal from the leading-edge position sensor and the obverse-/reverse-surface indication signal,
