A punching transport apparatus attached to an end surface a cylindrical inner surface drum includes two transport units which are connected with a pulse motor, two belts, and two pulleys so as to be able to move in synchronism to each other. The two transport units are linked to two punching units through linkage blocks. Transport carriers of the transport units are threadingly engaged with ball screws which are linked to the pulleys so that the transport carriers are loosely fitted to guide rails. Receiving an input signal which is entered in accordance with a plate edge distance which is determined by the specifications of a printer, a controller drives the pulse motor under the control of a pulse count. As a result, from an origin position which is determined in accordance with a condition which is detected by an origin sensor, the two transport units and the two punching units move in a central axis direction X.

Punching apparatus and punching method for cylindrical inner surface

A photosensitive material is mounted onto an inner surface of a cylindrical inner surface drum. An input signal which provides the size of the photosensitive material is supplied to a controller. As the controller drives a pulse motor under the control of a control signal, a moving part with which punching units are connected is moved in a circumferential direction of the drum by means of the pulse motor and positioned at the desired positions for punching. Then only two punching units, determined by the controller in accordance with the size of the photosensitive material, are driven to punch holes in the photosensitive material.

A travel roller moves between the initial and the end points in a loosening unit while supporting a photosensitive material to thereby form a loop thereof. A first sensor, for detecting that the travel roller locates on the end point, is provided in the loosening unit. When it is not detected at the end of recording that the travel roller locates on the end point, a portion of the photosensitive material is cut off, whereby the photosensitive material is divided into a sheet with a reproduced image and an unexposed photosensitive material. The unexposed photosensitive material is rewound until a leading edge portion thereof reaches a recording unit, and then an image to be reproduced next is recorded onto the unexposed photosensitive material.

An apparatus for laser recording of an image onto a selected length of photosensitive material has a loosening device positioned downstream from a feeding device for feeding the photosensitive material in a first direction so that the photosensitive material is loosened in a second direction to form a loop of a predetermined length selected by a user. In one aspect of the invention, the leading edge of the photosensitive material is held at a recording position. A cutting device is disposed between the loosening device and the feeding device and cuts off a photosensitive material sheet from the photosensitive material. An image to be reproduced is then recorded onto the photosensitive material sheet.

An image scanning apparatus comprises a linear light source being arranged in parallel with a picture plane to be scanned. The linear light source is composed of a cylindrical rod made of a transparent material on which light diffusing reflecting layer of stripe-shaped is provided along a longitudinal axis of the cylindrical, rod and a lighting means for entering light fluxes into the inside of the rod at least from one end thereof to emit light fluxes each having directivity from the outer surface of the rod.
