摘要： An image recording device and an optical fiber are provided which can obtain scanned beam spots having configurations which extend in an elongated manner in a subscanning direction and which are rectangular, and which are suitably used for recording onto a heat-mode-type photosensitive recording material. The image recording device records an image by illuminating a light beam outputted from an exposure head which is connected to a semiconductor laser unit via an optical fiber. In the image recording device, the optical fiber is an optical fiber having a core whose cross-sectional configuration in a direction intersecting an optical axis of the light beam is an elongated and a rectangular configuration. An image is focused by a focusing lens such that a short width direction of a light beam emitted from a light exit portion of the optical fiber is oriented in a main scanning direction on a recording medium.

摘要： An image-wise exposure apparatus includes a mirror array device comprising a plurality of small mirrors which are two-dimensionally arrayed in two directions normal to each other and a drive mechanism for changing the orientations of the respective small mirrors independently from each other so that light impinging upon each of the small mirrors is reflected selectively in one of a first direction in which the reflected light impinges upon the photosensitive material and a second direction in which the reflected light does not impinge upon the photosensitive material. A control circuit controls the drive mechanism according to an image signal. In the image-wise exposure apparatus, picture element shifting is carried out. There is provided an antireflective mask which limits the effective aperture of each small mirror to a continuous region not longer than 1.5 a/m as measured in a direction in which the picture element shifting operation is carried out, wherein a represents the mirror pitches in the direction of the picture element shifting and m represents the times by which the number of exposure dots are multiplied by the picture element shifting in the direction.

摘要： A radiation image read-out apparatus comprises a stimulating ray source constituted by many point light sources for sequentially emitting stimulating rays onto a portion of a stimulable phosphor sheet carrying a radiation image stored therein, and a line sensor constituted by many solid state photoelectric conversion devices. The line sensor extends over the length of the portion of the stimulable phosphor sheet linearly exposed to stimulating rays. Light emitted by the exposed portion of the stimulable phosphor sheet is received and photoelectrically converted by the solid state photoelectric conversion devices. The stimulating ray source and the line sensor are moved with respect to the stimulable phosphor sheet in a main scanning direction normal to the array of the solid state photoelectric conversion devices, and then moved with respect thereto in the array direction each time one main scanning step is finished.

摘要： An optical shutter array comprising a transparent substrate of a material exhibiting an electrooptic effect having parallel channels and electrodes of a conductive resin composition disposed in the channels can be driven with a lower voltage while minimizing cross-talk. Contact pads on the channel electrodes facilitate wire bonding to the electrodes, and a transparent dielectric film covering the substrate surface prevents damage to the electrodes by air discharge and provides abrasion resistance. The use of an anisotropic conductive connector and a flexible printed wiring connector ensures simple positive wire connection.
