Abstract: A travelling carriage driving apparatus includes a unit being controlled so as to be always located in a predetermined position, and a travelling carriage accommodating the unit. A guide mechanism allows the travelling carriage to be freely reciprocated. A deviation detecting mechanism detects a deviation of the unit from the predetermined position during the movement of the travelling carriage. A unit position adjusting mechanism is coupled to the unit and the travelling carriage, and moves in a predetermined direction, the unit accommodated in the travelling carraige. A controller controls the unit position adjusting mechanism in accordance with the detected deviation of the unit so that the unit is located in the predetermined position.

Abstract: A very stable deflection system usable with a beam of radiant energy incorporates a self-resonant scanning galvanometer located within an evacuated chamber. The chamber has a hermetic radiant energy transmissive window. An exterior laser source provides a beam of monochromatic light which is directed onto the mirror of the galvanometer. Repetitive deflection of the galvanometer mirror at a predetermined frequency results in the beam being projected onto a target so as to form a very stable and repeatable scanning line. Movement of the target provides a multi-line raster on which an image can be formed.

Abstract: A laser printer comprises two reference clock generators to define the rotational speed of a polygon mirror (main scanning rotational mirror); namely, a first reference clock generator which generates a clock signal whose frequency is set so as to correspond to a scanning line density for a millimeter system, and a second reference clock generator for generating a clock signal whose frequency is set so as to correspond to a scanning line density for an inch system. One of these clock generators is selected in accordance with the scanning line density of received image data. As the rotational speed of the polygon mirror decreases, a decrease and an increase in the image data density occur in the directions of main- and sub-scan, respectively, whereas as the rotational speed of the polygon mirror increases, an increase and a decrease in the image data density occur in the directions of main- and sub-scan, respectively.

Abstract: A servo system for a braked accelerative transport in which a signal representing velocity of a carriage within the transport is compared to a first reference signal representing desired carriage velocity. The comparison yields an error signal which is used to adjust the brake of the transport. A hydraulic valve having an adjustable needle is used as the brake. A second selectable reference signal is provided so that the first reference signal can be bypassed when the carriage is reset at high velocity or is at reset. The valve is also bypassed on reset so that the adjusted brake mechanism is left intact on reset.

Abstract: A light beam scanning device in which a light beam is scanned over an image or recording surface at a constant velocity independent of beam position and disturbances in the drive to the system. A position detecting device produces a signal representing the position of the light beam over the surface with the light beam being scanned by an optical deflector device. A feedback loop such as a phase-locked loop controls the movement of the optical deflector in response to a signal produced by the position detecting device and a reference signal.

Abstract: A raster scanner has a laser as a source of a scan beam, an optical system including a rotating polygon for scanning the laser beam across the object to be scanned, and a detector pair for identifying the start-of-scan (SOS) and end-of-scan (EOS) positions of the beam scanning path. One or both detectors are modified to incorporate a peak responding circuit which produces a signal whose voltage level represents the maximum light intensity of the scan beam as the scan beam scans across the detector or detectors. The peak responding circuit includes an output tap permitting the peak signal to be read by a suitable voltage reading meter.

Abstract: A facsimile recorder has a motor driving a scanning element and also generating recorder pulses occurring proportionally to the recorder scanning speed. A circuit for synchronizing the scanning motor with incoming framing pulses of a facsimile signal comprises a first dual data type flip flop with a first output, a first input receiving the framing pulses and a second input receiving the recorder pulses. The flip flop produces a gating pulse of duration corresponding to the interval between asynchronous occurrence of framing and recorder pulses which causes transmission of power to the recorder motor during the asynchronous interval. Consequently the motor speed and hence the period of the recorder pulses are varied in proportion to asynchronism until the framing and recorder pulses are coincident when the motor is synchronous with the framing pulses.Power is transmitted to the recorder motor at a particular frequency derived from a frequency standard. In addition to varying the time the power is transmitted the frequency of the power and hence the speed of the motor is varied by a second flip flop so as to reduce the time needed to bring the motor into synchronism with the received framing pulses.
