Abstract: A stimulable phosphor is exposed to a radiation passing through an object to have a radiation image stored therein, and then exposed to stimulating rays to read out the radiation image and obtain an electric image signal. The image signal is processed under conditions suitable for the type of image recording and used to reproduce a visible image. The conditions of exposure to the radiation and the image processing conditions are adjusted by a single action of selecting the setting conditions predetermined according to the type of image recording. Also, read-out of an identification code provided on the stimulable phosphor and the exposure of the radiation are started by a single action. Or, the read-out of the identification code is conducted in response to memorizing of information on the object.
Abstract: The present invention provides an ink dot printer wherein an electrostatic field is produced between ends of needles and an electrode, and the needles are selectively actuated to cause ink sticking to the ends of the needles to fly with a Coulomb force thereby to form dots with ink thus flown on record paper which covers the electrode without contacting the needles with the record paper. By this construction, noises are signficantly reduced and the ends of the needles are not damaged while printing results of a high resolution can be obtained. In addition, a tapered configuration of the ends of the needles will facilitate separation of the ink from the needles, assuring the uniformity of dots in shape and size. In case a positive voltage is applied to the electrode while the needles are grounded, treatment for insulation can be performed easily, allowing production of printing heads with ease and at a reduced cost.

Abstract: A light beam scanning and recording device for optically reading a form slide with a raster scan, combining a signal representing the form with a data signal and recording the combined information on a recording sheet also using a raster scan. A portion of a beam scanning the form is split off and directed through an optical encoder device having an alternating transparent and opaque pattern. A detected signal from the encoder is used to detect shifts in the raster scan pattern and to consequentially properly align the data signal with the form information by controlling a clock signal synchronizing the data signal. A common optical system including vertical and horizontal beam deflectors is employed for both reading and recording beams.

The format line data memory is provided with a horizontal pattern memory and a vertical pattern memory. The horizontal pattern memory memorizes various horizontal patterns in the direction parallel to the scanning line of the light beam scanning means. The vertical pattern memory memorizes the kind of the horizontal pattern according to the position of the scanning line. The vertical pattern memory generates the horizontal pattern code according to the scanning line signal and the horizontal pattern memory generates the selected horizontal pattern for every scanning line.

Abstract: A format pattern carried on a format transparency is photoelectrically converted into an electric signal. The electric signal representing the format pattern is inputted into an "exclusive-or" circuit together with a character pattern signal representing output information of a computer. The output of the "exclusive-or" circuit controls an on-off modulator which modulates a laser beam for recording the output information of the computer. The modulated laser beam is deflected by a beam scanner to scan a photosensitive or heat sensitive film to record thereon the format pattern together with the computer output information.
Abstract: A dot character recording device in which a recording surface is scanned with a laser beam modulated in accordance with the dot patterns of characters to be recorded. The time width of the modulating signal is adjusted in accordance with the beam position in order to maintain a constant scanning line and hence character dot width. Preferably, the pulse width of the modulating signal is increased in the scanning direction at recording positions where the density of the beam would otherwise be low so as to apply additional optical energy.
