This invention relates to a radiographic apparatus which comprises a radiographic image photographing unit for photographing a radiographic image of an object irradiated with radiation by a radiation generating device, a distance measuring system for measuring the distances or distance from the radiation generating device to the radiographic image photographing unit and/or the object, and distance information indicating means for indicating distance information obtained by the distance measuring system.

Radiographic apparatus

A method for manufacturing a semiconductor apparatus for detecting radiation provided with phosphor comprises the steps of forming a phosphor layer integrally with a meshed partition plate having partitions per pixel of the semiconductor apparatus for detecting radiation, and of separating the phosphor per pixel by removing the phosphor on the partitioning portion of the partition plate by the irradiation of laser beam in the form of grooves together with the surface layer of the partitioning portions in order to make the phosphor thick to obtain a higher sensitivity, and also to make pixel pitches finer to enhance resolution, thus obtaining exact images without creating any cross talks between pixels.

Apparatus for detecting radiation and method for manufacturing such

A large-area, compact and highly reliable radiation detector is produced by a process comprising the steps of laminating a phosphor sheet to a substrate having at least a photoelectric transducer, a driving element and a wiring matrix, and sealing the phosphor sheet and substrate thus laminated, by imparting a sealing medium to at least part of the peripheral portions of the phosphor sheet and the substrate, at least one of the steps being carried out in a vacuum chamber, to thereby bring the phosphor sheet into close contact with the substrate by atmospheric pressure.

Radiation detector and process for its production

A sheet carrier apparatus of the present invention includes a first and a second rotary roller member, at least one of them having a rotary driving force. The second rotary roller member is constructed so as to be able to rotate around the first rotary roller member while it is being driven by the first rotary roller member. In order to control these rollers, the sheet carrier apparatus includes a control device for selectively setting the direction in which a sheet is moved from among a plurality of directions by controlling the rotary driving of the rotary roller members while carrying a sheet and by controlling the degree of angular displacement causing the second rotary roller member to rotate around the first rotary roller member while a sheet is grasped between them.

Sheet carrier apparatus and a picture image recording apparatus

The sheet conveying unit of the present invention has a roller for conveying a sheet which contacts therewith, a supporting portion for rotatably supporting both sides of the roller, a drive motor for rotatively driving the roller, and a frame portion for holding the supporting portion and the drive motor and making them integral with each other. The rotary shaft of the roller and the rotary shaft of the drive motor are a common shaft. The rotor of the drive motor is mounted on the common shaft, and the stator of the drive motor is mounted on the frame portion.

In an image recording apparatus, a supply magazine and a receive magazine are arranged almost in a row, and a sheet transport path is formed along the periphery of both magazines. A recording sheet, which is taken out of the supply magazine, is once moved to a path whose transport resistance is small, so that the trailing edge of the recording sheet is completely out of the supply magazine. Then, a subscanning operation for image recording is performed along the path whose transport resistance is small.

Image recording apparatus

An apparatus for adjusting the inclination of an optical element or the like is provided with a predetermined shaft, an optical element fitted to the predetermined shaft, a mounting seat for supporting the optical element, a keep member for holding and fixing the optical element between it and the mounting seat, and a spherical seat movable in a direction intersecting the predetermined shaft between the mounting seat and the optical element for adjusting the inclination of the optical element. A method for mounting and adjustng the optical element includes the steps of mounting the optical element on the spherical seat supported on the predetermined shaft, detecting an inclination angle of the optical element and shifting the spherical seat to adjust the optical element.

An image recording method having a first step of recording an image on a first area of a recording medium by the major scanning by a light beam scanning optical system and a first subsidiary scanning in which the recording medium is moved relative to the light beam scanning optical system in a direction intersecting the major scanning, and a second step of recording an image on a second area of the recording medium by the major scanning and a second subsidiary scanning in which the recording medium is moved relative to the light beam scanning optical system so that the first area again crosses the scanning area of the light beam scanning optical system.

Light beam image recording apparatus having commonly driven member

An image recording apparatus has a feed system for feeding a recording sheet from a feed magazine to a drum, a drum system for winding the recording sheet therearound and rotating to align the recording position with a predetermined position on the circumferential surface of the drum, a scanning system for main-scanning the recording sheet at the recording position of the sheet with an optically modulated beam, and a storage system for storing the recording sheet on which an image has been formed. The drum is rotated in opposite directions during feed and storage of the sheet.
