  • Patent number: 4648685
    Abstract: A sawtooth voltage waveform for driving a galvanometer mirror is applied until the voltage reaches a peak value exceeding a prescribed voltage value at which the galvanometer mirror is angularly displaced through a maximum angle at one stroke end of reciprocating angular movement thereof. The voltage is then changed from the peak value to the prescribed voltage value after the galvanometer mirror has been angularly displaced through the maximum angle. The voltage is kept at the prescribed voltage value for a time interval to attain a desired period of the reciprocating angular movement of the galvanometer mirror. The voltage may be increased along a ramp or reduced along a fall toward the peak value.

  • Patent number: 4535342
    Abstract: A recording laser beam is intensity-modulated and is caused to scan a photosensitive recording material in both the main and sub scanning directions. The position of the recording laser beam on the recording material in the main scanning direction is detected and position reference pulses are generated each time the laser beam moves along the recording material in the main scanning direction by a predetermined constant distance. The recording laser beam is intensity-modulated only for a predetermined constant time interval between each pair of adjacent position reference pulses and is made essentially null for the rest time interval between the adjacent position reference pulses so that a unit area of the recording material corresponding to one picture element is exposed to the recording laser beam for a predetermined constant time interval regardless of fluctuation in the scanning speed of the recording laser beam.

  • Patent number: 4484073
    Abstract: In a system for reading out radiation image information recorded on a stimulable phosphor sheet which emits light upon stimulation by stimulating rays according to the recorded radiation image information, the phosphor sheet is two-dimensionally scanned by a laser beam and the light emitted therefrom is detected by a photodetector. The integrated output of the photodetector is read out for every unit of time period corresponding to a picture element of the radiation image. Position reference pulses are generated every time the relative position of the laser beam scans on the phosphor sheet by a standard amount in the main scanning direction. The integrated value of the output of the photodetector is read out every time the output is integrated for a fixed time period within each time interval between the position reference pulses.
