Abstract: Film boxes for attachment to and use with a camera are keyed and secured by thumb screws to a shutter housing of the camera to permit detachment and accurte reattachment. Light restrictive devices negate transmission of light into each film box upon removal of same. A longitudinally displaceable film reel drive permits rapid disengagement and reengagment of the film boxes without careful alignment and a belt drive prevents, through slippage, film tearing forces.

Abstract: Device for connecting two components of a motion-picture camera. A thermal expansion compensation pendulum (Rost pendulum) (3) is disposed between the two components (10, 11), said pendulum being composed of a first element (31) connected with one component (11), a second element (32) connected with the component (10), and at least one intermediate element having axial and/or radial play between both elements (31, 32) and being connected therewith. The coefficient of thermal expansion of the intermediate element or elements (33) is a multiple of the coefficients of thermal expansion of the first and second elements.

Abstract: A color image recording apparatus records a color image on a photosensitive recording medium by repeating exposure against the photosensitive recording medium successively through mask members for red (R), green (G) and blue (B) images. The apparatus includes a memory having two (or more) conversion tables (I) and (II) for exposure conditions to be set on a panel surface by an operator. The conversion table (I) indicates exposure scanning speed corresponding to the exposure conditions to be set on the panel surface, and the conversion table (II) indicates one or plural stages of different scanning speeds correlative with each of the scanning speeds indicated by the conversion table (I). In deciding the exposure conditions by trial printing, a trial print mode is set, and keys are operated to carry out exposure per image area in plural stages of scanning speeds defined in the conversion tables (I) and (II).

Abstract: An image recording apparatus capable of providing an intended numbers of output copies regardless of the mask member feed mode. A set of the mask members are automatically fed from a laser printer to a color copying portion after the set is produced at the laser printer. Further, another set of mask members already on hand can also be set on a mask member tray, and the another set can be delivered to the color copying portion. The mask members are normally printed with bar codes indicative of the numbers of the output copies. The bar codes can be invalidated in case of the mask feed mode from the tray, and newly input numbers of copies are obtainable in the mask feed mode from the tray.

Abstract: An image recording apparatus having a sheet cartridge which stores therein an elongated photosensitive recording medium. A locking mechanism is provided selectively engageable with the sheet cartridge or a light shielding member which is positioned to prevent the cartridge from being exposed to light. A control means is provided to provide locking state of sheet cartridge or the light shielding member by controlling the locking mechanism to its locking position. This control is made in response to a signal indicative of the installation of the sheet cartridge at its predetermined position. The control means is also adapted to provide unlocking state of the sheet cartridge or the light shielding member by controlling the locking mechanism to its unlocking position. This control is made in response to a signal indicative of the complete discharge of the elongated photosensitive recording medium out of the sheet cartridge.

Abstract: A microfilm reader/printer for selecting a desired image from images recorded on a microfilm roll to print the desired image, the images being recorded by the duo photographing system in two channels so that the images recorded in one channel are in the normal orientation while the images recorded in the other channel are in the inverted orientation. Desired images are printed by the microfilm reader/printer always in the normal orientation irrespective of the orientation thereof recorded in either one of the two channels on the duo mode microfilm automatically without the need of manual operation. Channel exchanging means and image rotating means are combined so that orientation of images is inverted every time the channel being retrieved is exchanged so as to display or print desired images in the same orientation. The channel exchanging means may be mechanical or optical means, and the image rotating means may be optical or electronic image processing means.

Abstract: A front projection composite photography system using a pair of perpendicular reflex screens combines two projected background scenes with a staged scene in a single camera shot for a versatile range of special effects. Complementary mattes are used outside the projectors and camera for either soft or hard edged merging into overall projected background scenes. A camera-projector housing cabinet includes all elements compactly except for stage reflex screens which are externally located in a small studio room. A lens permits use of a small secondary reflex screen used with a larger primary screen behind a movable stage setup. The camera, two projectors and respective associated three half mirrored transparent beam splitters provide registration adjustments for registration of all composite picture portions for immediate observation through the camera viewfinder so the film will be properly aligned and so that a complex composite picture may be produced with a single camera take.

Abstract: According to the method of the invention, photographic media are transported from one treatment station to another by means of a conveyor belt (1) on which they are held by temporary adhesion by using adhesive means, said media (10) being then removed from the belt by means of an extractor (9). The adhesive means have, with respect to the belt (1), an adhesive power different from the adhesive power they have with respect to the medium (10), so that, during the extraction phase, they remain either on the belt (1) or on the medium (10), according to the desired aim. The invention allows to improve the performances and to extend the application fields of apparatuses using the transfer principle by conveyor belt with temporary adhesion.

Abstract: Variable magnification optics for an image forming apparatus has a plurality of optical members, especially a first mirror and a lens located at the rear of the mirror, which are movable in association with each other and over a minimum of distance. This reduces the exclusive space which the optics occupies in the apparatus and, therefore, the overall dimensions of the apparatus. The mirror and lens which are interlocked with each other do not need independent drive lines, whereby the overall dimensions of the apparatus are further reduced.
