Abstract: A control device includes: a print data acquisition unit configured to acquire print data, which is formed of a plurality of lines and indicates a coloration state of each pixel included in the plurality of lines; a head drive unit configured to supply, to a thermal head formed of a plurality of heating elements each corresponding to the pixel, an electric current for heating the thermal head for each pixel; a motor drive unit configured to supply, to a motor configured to move heat-sensitive paper relative to the thermal head, a drive current for step driving the motor for each line; a speed control unit configured to control, based on the number of colored pixels of a determination subject line among yet-to-be-printed lines of the print data, a relative moving speed of the heat-sensitive paper moved by the motor; and a preheating control unit configured to cause the head drive unit to output, when the determination subject line is a specific line being a line in which the number of colored pixels of the det

Abstract: A laser therapeutic apparatus for treating a patient by irradiating selected body parts by laser beams generated by a plurality of laser probes. The laser probes are supported by a common support table and a lock mechanism is provided to selectively lock and release the laser probes to maintain and release the orientation thereof. Each laser probe includes an inner cylinder and an outer cylinder and a spring for biasing the inner cylinder axially within the outer cylinder. The end of the inner cylinder is provided with one or more lights that are energized when the associated probe is emitting a laser beam. The end of each laser probe further includes indicating rings for visually indicating the extent of the axial movement of the inner cylinder with respect to the outer cylinder.

Abstract: A laser therapeutic apparatus having an oscillator for generating a laser beam, a condenser lens for condensing the laser beam radiated from the oscillator, a plurality of optical fiber cables for guiding the condensed laser beam, and a probe connected to the distal end of each of the optical fiber cables to apply the laser beam to an affected part of a human body. The probe may be detachably connected to the distal end of the optical fiber through an optical connector. A plurality of optical fibers may have their respective laser beam emergent ends dispersedly disposed over the distal end portion of a probe casing constituting the probe. There may be prepared detachable cap-shaped attachments having various sizes which are conformable with various affected parts of patients, and a selected one of the attachments may be attached to the distal end portion of the probe casing. Thus, it is possible to carry out laser therapy efficiently and effectively.
