A paper feeder for a printer having a platen and a printing member disposed in confronting relation to the platen includes a pair of slide blocks which can be moved to vary the spacing therebetween dependent on the width of recording paper placed on the platen, each of the slide blocks supporting a track rotating body having a plurality of pins mounted on a peripheral surface thereof and spaced at prescribed intervals, a paper holder member confronting the track rotating body, and a drive roller. A drive shaft is disposed in each of the slide blocks for driving the track rotating body and the drive roller. A roller shaft supports thereon a pair of pinch rollers for contacting the drive rollers, respectively, and is movable away from the slide blocks, the pinch rollers being held by the paper holder members for slidable movement along the roller shaft in response to movement of the slide blocks.

Variable width paper feeder for perforated and unperforated paper

In a moving object, such as automobile, having a steering gear which determines a traveling course, and a traveling distance detector which detects a traveling distance; a direction detection apparatus comprising a steering position detector detecting an amount of displacement of the steering gear, and an arithmetic unit which calculates a traveling direction of the moving object from a steering position signal proportional to the amount of displacement and a traveling distance signal proportional to the traveling distance, thereby to detect the traveling direction of the moving object. The apparatus can detect the traveling direction without being affected by a magnetic deviation, an abnormal magnetic field, etc.

Direction detection apparatus

A direction detection apparatus comprising a magnetic sensor which senses a geomagnetic azimuth, a turning-angle sensor which senses a turning angle dynamically, a magnetic-disturbance detector which detects a magnetic disturbance on the basis of the output of the magnetic sensor, and a signal switching device which transmits either the magnetic sensor output or the turning-angle sensor output to a display device in accordance with a signal from the magnetic-disturbance detector. The traveling direction of a moving object can be detected as a precise geographic azimuth even when the moving object lies in a place subject to the magnetic disturbance.

A composite switch assembly including in a cylindrical rotary knob, four contact mechanisms in which four quadrantal push buttons are combined and arrayed into a circular form and which are operated by the four push buttoms respectively, and two contact mechanisms which are operated by turning the rotary knob clockwise and counterclockwise respectively, thereby to permit a switch arrayal and a control configuration corresponding to the moving directions of a controlled object.

Composite switch assembly

A direction detection apparatus which detects the traveling direction of a moving object on the basis of the movement of a weight. It comprises a centrifugal force detector, a clock signal generator, and a velocity detector, and also a detection device which receives signals from the detectors and the generator to provide a directional angle.
