Abstract: A photosensitive material such as film is conveyed while the widthwise edges thereof are guided by width guides. The width guides have an adjusting part such as a screw to adjust the position thereof when the width of the photosensitive material changes. The adjusting part, even when the width dimension of the sensitized material does not change, is driven at a specified interval such as every few hours to remove a precipitate such as a developer which is deposited on the adjusting part.

Abstract: A film holder provides a lighttight environment where a film unit may be inserted while enclosed within a lighttight envelope. After insertion the envelope may be removed from the film unit to allow the exposure of the film unit by a source of electromagnetic radiation mounted on one wall of the holder. The source of electromagnetic radiation is mounted on a block to reciprocate back and forth toward the film surface to allow the source of electromagnetic radiation to press against the film unit when the envelope is retracted from the holder and the block may be withdrawn from contact with the film unit to allow the reinsertion of the envelope to cover the exposed film unit.

Abstract: An automatic focus state detecting apparatus is capable of focus detection with respect to an object in different focus state detection areas, such as a narrow area or a wide area of an object field, or in areas extending in different directions in the object field. The focus state detecting area may be selected automatically or manually, and the automatic selection may depend upon whether the object is stationary or moving, and the direction of movement. Automatic switching between narrow and wide focus state detecting areas may occur after an in-focus state or a nearly in-focus state is obtained in the narrow area, after a predetermined time has elapsed from the selection of the narrow area, or after a predetermined number of focus detecting operations in the narrow area. Defocus amounts may be calculated for a plurality of sub-areas of the wide area. The defocus amount or a lens driving amount may be limited when the wide area is selected.

Abstract: In a camera capable of recording sound data corresponding to photographed frames of a film respectively, the sound data can be recorded in a first memory (e.g. a sound IC card), and data indicating correspondence between the photographed frames of a film and the sound data respectively can be recorded in a second memory (e.g. a film). Though the first memory, namely, the sound recording memory and the second memory, namely, the film are separate, the recorded sounds can accurately correspond to the photographed frames of the film respectively.In a sound playback apparatus, by attaching thereto a medium in which sound data are recorded in each area thereof and a print in each frame of which a code indicating a sound recording area is recorded, the sound playback apparatus can play back sound data corresponding to the photographed frames of the film respectively from the medium.

Abstract: A clamp is provided at the nut of a guitar for clamping the strings to prevent them from sliding across the nut. The clamp was a boss portion in which a bore is formed. A set screw is provided in one end as a plug. A screw with a handle is threaded into the other end of the bore and six cylindrical spacers are disposed between the plug and the screw with the handle. Slots are cut in the boss which expose the ends of the spacers so that the strings of the guitar can be slid between the ends of the spacers. Tightening the screw with the handle clamps the strings between the spacers. The clamp has a step, formed on one side of it, on which a nut is mounted. The nut is divided into three sections whose heights and orientations are adjustable to suit the camber of the fret board of the guitar and the height of the frets, so as to eliminate the need for shimming or filing the nut.

Abstract: An image forming apparatus for forming an image on a photosensitive recording medium by exposing the photosensitive recording medium to light by way of a mask member which is placed on an exposure station. The apparatus comprises a first transport device which transports the mask member through the exposure station and a second transport device which transports the photosensitive recording medium through the exposure station. A first exposure unit irradiates light upon the photosensitive record medium by way of said mask member at the exposure station to record an image formed on the mask member on the photosensitive recording medium. Alternatively, when a mask member is not used, a second exposure unit directs light through an auxiliary member having a light-passing image thereon to project and record the light-passing image onto the photosensitive recording medium.

The shape of the corrugations of the damper increases as the position approaches from the inner periphery to the outer periphery.

Abstract: An image recording apparatus forms the image by using a photo-sensitive sheet accommodated in a cartridge, one side of which has a bar code attached. In this recording apparatus, a remaining amount of the sheet in the cartridge at a given time is calculated by substracting a used amount of the sheet detected by a rotary encoder installed on a motor shaft of a sheet feeding device from a total amount of the sheet detected by reading the bar code through a bar code reading device, and is displayed on a display. And, this recording apparatus corrects the remaining amount of the sheet in the cartridge based on a rewound amount of the sheet detected by the rotary encoder when a single copy mode is selected. Further, the apparatus displays copyable numbers according to the remaining amount of the sheet based on a copy size set.

Abstract: A dedicated electronic flash unit for automatically varying flash spread based on camera-to-subject distance. Specifically, in one embodiment, a light source includes a flash tube mounted adjacent a reflector. An actuator comprises an electric stepper motor for controlling the movement of a pair of opposed diffusion plates. The actuator includes a pair of armatures that are energized, in response, to the output of the camera's rangefinding system. When a photograph is to be taken, the diffusion plates are pivoted by the actuator to one of three different positions. In one position, the neutral position, the diffusion plates are positioned on opposite sides of the reflector. In a second position, the actuator pivots the diffusion plates such that one of the plates covers the light output of the reflector to create wide-angle illumination of the subject.
