Abstract: A form feeding control device includes a sensor provided at an inlet mouth of a printer to sense whether or not a continuous form exists in the inlet mouth. A control unit feeds the continuous for transfer thereto of a printed image corresponding to one page of the continuous form. The printed image is then fixed on the continuous form. The control unit also feeds the continuous form to fix the printed image on one page when the sensor senses that the end of the continuous form has passed through the inlet mouth and that a printed image has been transferred to the continuous form.

Abstract: In a printer for printing information onto a continuous form, at least one of opposite side edges of the continuous form is detected by a side-edge detecting arrangement. It is judged that a traveling abnormality of the continuous form occurs, when a detecting signal representative of the at least one side edge of the continuous form detected by the side-edge detecting arrangement continues for a preset period of time and more. If the continuous form is provided therein with sprocket holes, the side-edge detecting arrangement may include a pair of side-edge detectors each for detecting the sprocket holes in a corresponding one of opposite side edge portions of the continuous form. In this case, it is judged that the traveling abnormality of the continuous form occurs, when the detecting signal representative of the sprocket holes in each side edge portion of the continuous form is not continuously outputted within a preset period of time and more.

Abstract: A justification system for use in an electrophotographic printer. The justification system comprises a detector which detects pulses occuring at intervals each covering a segment of a continuous form. A counter coupled to the detector counts the number of main scannings over the surface of a photoconductive drum during the time to feed each segment, as confirmed in the detector. The counted value is compared with a reference value by a differential arithmetic unit, the output of which is fed to a speed control to control the feed speed of the continuous form. This compensates for the fluctuations in printing positions of each segment due to systematic errors such, as expansion of the continuous form.

Abstract: A lens frame holding device for mounting the optical unit of a copying machine in which the position of the lens frame in the direction of the optical axis is regulated so that, if a lens frame is removed from the housing for maintenance or the like, it can be easily and accurately reassembled without the need for adjustment. A housing has bottom and vertical walls at opposite ends of the bottom wall, and supporting cuts are formed in the vertical walls for supporting the lens frame. Two hooking slots are formed in each vertical wall, and elastic lens holding members are provided for securing the lens frame to the housing. The lens holding members each having two hooking portions adapted to engage with the hooking slots. With the lens holding members laid over the lens frame set in the supporting cuts, the lens frame is fixedly secured to the housing using the hooking portions and hooking slots.

Abstract: A zoom lens barrel for a variable magnification type copying machine in which the lenses are readily mounted and adjusted and the optimum angular positions thereof employed. Two movable lenses are fixedly held by respective movable lens frames, the latter being inserted into an axial hole formed in a single movable lens barrel which is moved in the axial direction as the magnification setting of these zoom lenses vary. At least one of the movable lens frames is fixedly secured to the movable lens barrel, while the other movable lens frame is supported in the movable lens barrel in such as a manner as to move in the axial direction as the magnification changes. The one movable lens frame includes a first mechanism for adjusting the angular position of the one movable lens frame with respect to the movable lens barrel without moving the movable lens frame in the axial direction, and a second mechanism for adjusting the position of the one movable lens frame in the axial direction thereof.

Abstract: A varying magnification copying device of small size and low manufacturing cost in which a region of movement of a zoom lens system for an enlargement copying operation is shared with a region of movement of a half-speed mirror for the equal magnification and reduction copying operations. The zoom lens system is moved along the optical axis thereof by a feed screw rotated by a digitally-controlled stepping motor. The zoom lens system, which includes front and rear frames varying front and rear lens systems, is adjsuted in magnification factor by a cam and cam follower mounted on the rear and front frames, respectively. The cam is rotated by a pinion gear which is engaged with a rack which extends parallel to the feed screw. Movement of the zoom lens system perpendicular to the optical axis is accomplished through a lead cam and cam follower.
