Image information handling device

An image information processing device, comprising:

• means for deflecting a light beam;
• means for modulating the light beam by a pattern signal in synchronism with said deflection;
• means for polarizing the light beam;
• means sensitive to the light beam as deflected and modulated;
• means disposed in the path of said light beam for varying the plane of polarization of said polarized light beam;
• and
• means for directing a light beam having a different plane of polarization to a different light path,
• whereby the magnification of said light beam on said sensitive means can be varied.

A light information recording device, comprising:

• a light beam generator;
• a light modulator for modulating the light beam generated from said generator, by an external information signal;
• a galvanometer mirror for automatically defining the path for the modulated light beam by an external signal;
• a plurality of beam expanders along a plurality of beam paths, each beam expander providing a different magnification of beam diameter of the light beam when the beam passes therethrough;
• reflector means disposed on the output side of said beam expanders for directing the light beam to a common scanning means;
• and
• an optical lens for image-forming the scanned light beam on a light beam recording medium;
• whereby light information of a desired magnification may be recorded by the selection of any one of said light beam paths.

An image information processing device, in which a light beam is modulated by an image information signal and the modulated light beam is focussed on a light beam sensitive medium, said device comprising:

• a light beam generator;
• means for providing, a character code signal and character size signal;
• an interace circuit;
• a buffer circuit for said character code signal;
• a buffer circuit for said character size signal;
• a character generator;
• control means connected to said character code signal buffer circuit, said character size signal buffer circuit and said character generator, said control means controlling systematically the generation of a high-frequency signal for light beam modulation, the scanning of the light beam, and the change character size;
• a high-frequency signal oscillator connected to said control means;
• driver means for scanning means connected to said control means;
• driver means for character size changing optical means connected to said control means;
• a light beam modulator connected to said high-frequency signal oscillator;
• optical scanning means connected to said driver means for scanning means;
• and
• character size changing optical means connected to said driver means for the character size changing optical means,
• said optical scanning means and said character size changing optical means being operated in a predetermined relationship by said control means, and said character size changing optical means being operated in response to a character size changing signal input.

An image information handling device comprising:

• means for modulating a light beam by an image information signal;
• a medium for receiving the modulated light beam;
• scanning means for causing the modulated beam to scan said medium;
• and
• optical means between said modulating means and said scanning means for selectively directing the modulated beam along any one of a plurality of light paths extending to said medium, said optical means also being effective to vary the image forming characteristic of the light beam incident on said medium.
