Abstract: PROBLEM TO BE SOLVED: To prevent paper from coming off from a tractor in the midst of printing and a sprocket hole from being broken or the paper itself from being torn in the midst of carrying paper even when the paper is thin by changing tension in the case of carrying the paper in accordance with the thickness of the paper. SOLUTION: In the case of printing on the thin paper, the switching knob of a cam is operated by a changing means 20 so as to switch a condition to a thin paper printing condition, and an interlocked switching pawl 18 is also switched. Namely, the switching knob is turned counterclockwise to press the abutting edge of a brace by a cam surface. Thus, the tension for pulling continuous paper P in the carrying direction is changed to be small. Therefore, the paper P on which a toner image is fixed is ejected to an ejection roller 19 side by the pawl 18 in the printing device 1.  In the device 1, the tension in the case of carrying the paper P being the thin paper is changed to be a small value corresponding to the thin paper from a value corresponding to plain paper, whereby the paper P is prevented from coming off from the tractor 11, the sprocket hole of the paper P is prevented from being broken or the paper P itself is prevented from being torn in the midst of carrying the paper.

Title: Diode pumped laser system and its method
Inventor: JOHN G SUUSA
IPC: H01S3/094
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To promote reduction in the opening of beams, without the damage to output density by converting divergent arriving beams into a single-mode output by means of a laser crystal executing optical pumping. SOLUTION: The output of a laser 60 is pumped by a laser crystal 75 and that which actually reaches a recording medium 50 is the beam which is emitted from the laser crystal 75. A series of lenses 77 and 79 converge the outputs of the laser 60 to an end face 85 of the crystal 75. The laser beams are distributed, when they leave a slit 69 of the laser 60 and they diverge at the end part of the slit. Thus, the end faces 85 and 87 are bent in a bow form with the optical output supplied to the end face 85 of the crystal 75 so as to form a resonance cavity part. Consequently, the laser output is generated. For generating a smooth imaging spot, it is desirable that a single cross-operation mode, having output divergence which approximates as much as possible to the output divergence of a source whose diffraction is restricted be obtained.
