Abstract: A perforator for making perforations in a continuous film which is thereafter cut into individual filmstrips having variable lengths. A die set unit of the perforator has a plurality of punches and corresponding dies which are respectively arranged along the continuous film. The die set unit performs die-punching N times (N=1, 2, 3 . . . ) in every first section having a variable length Lx, and the measuring feeder transports the continuous film by a first length after each of (N−1) times die-punching and by a second length after the last die-punching for every first section. The first length is given as Lx/N, and the second length corresponds to the first length plus the length L2 of a second section disposed alternately with the first section along the continuous film. In alternative, the die set unit is constituted of first to nth die sets aligned in order from downstream to in the film transporting direction. The ith die set of the die sets has a number Gi (i=1, 2 , . . .

Abstract: A photo filmstrip (10) has a length from a front end to a rear end (10a), and the length is different according to a strip type. To wind the photo filmstrip about a spool (36), at first, the front end is retained on the spool. The photo filmstrip is wound about the spool at high speed by rotating the spool fast. After the high-speed winding, the photo filmstrip is wound about the spool at low speed by rotating the spool slowly. During the low-speed winding, the rear end is detected at a photo sensor (47, 84, 99) disposed a first distance away from the spool rotated in the low-speed winding. The spool is stopped from rotating upon detecting the rear end, to regularize a length of an unwound portion of the photo filmstrip irrespective of the length of the photo filmstrip.

Abstract: A side printing apparatus includes a plurality of light emitting members arranged in a line perpendicular to the forward direction of a film so as to provide several kinds of dot patterns which are exposed on the film as latent images of characters, symbols and so on. A detector for detecting the film position is provided to produce position signals which operate to cause a control to drive selectively the light emitting members to emit light in accordance with the position signals. The light rays from the light emitting members are focussed on the film as light spots.

Abstract: A side printing apparatus for providing latent images of information marks, such as manufacturer's name, date information, film size, frame numbers and the like at the longitudinal sides adjacent each picture frame of a photosensitive product, is adapted to scan the surface of the photosensitive product moving with continuous motion with a deflecting device which deflects a beam of laser light in a direction perpendicular to the direction of the continuous motion of the photosensitive product. Before the deflection, the beam of laser light is modulated according to the pattern of marks by which the latent image is required to be provided on the photosensitive material.

Abstract: A side printing apparatus for providing on a continuously moving film latent images of characters, numerals, symbols and the like which are later photographically developed. The light image forming arrangement is deenergized so as to prevent the provision of such light images at least during the movement of the film in a reverse direction for preventing double exposure of the film. The deenergization of the light image forming arrangement is caused by a direction discriminator for discriminating the movement of the film in the forward and reverse directions in conformity with two series of pulse signals with a phase difference of 90.degree. therebetween from a rotary encoder rotating in synchronism with the movement of the film.

Abstract: A printing apparatus for printing a colored mark in a colored dot pattern on a colored light sensitive material which is moving. A plurality of picture element display sections are aligned in a row perpendicular to the direction of movement of the colored light sensitive material, each of the plurality of picture element display sections emitting a single colored dot, and selectively emitting light to form a dot pattern. Each of the picture element display sections comprises a plurality of sources of lights of different colors, and a plurality of light guides for transmitting the respective colored lights. The outlet ends of the plurality of light guides are regularly arranged so that the light guides transmitting different colored lights are adjacent to each other, thereby mixing the different colors of lights. By changing the intensity of the light sources, a colored dot having the desired color and intensity is produced.

Abstract: A side printing apparatus for providing latent images of characters, numerals, symbols and the like on a photographic film moving in continuous motion includes a film sensitivity responsive means for generating several kinds of pulse having different pulse lengths which are predetermined in accordance with sensitivity of film. The pulse operates to cause a light image forming device to be energized for a time defined corresponding to the pulse length thereof so as to provide a latent image of character, numeral, symbol or the like on a photographic film.

Abstract: A side printing apparatus for photographically exposing marks onto a strip of continuously moving photosensitive material as a latent image that includes a multielement luminous display unit with a plurality of light emitting elements arranged at regular intervals. The image of the displayed mark on the multielement luminous display unit is focused on the lengthwise moving photosensitive material through a reduction lens system. The light emitting elements are selectively driven to display different marks according to various types of photosensitive materials.
