| A paper stacker for use with a printer which prints connected sheets that are to be stacked in a folded relationship having a surface for receiving the paper with a frame surrounding the paper that is raised in relationship to the paper in order to maintain paper within the confines of the frame as the frame moves upwardly. The frame is balanced by a constant force spring, and is indexed by optical sensors. The frame includes two adjustable fences for variously sized paper which adjustably moves with paddles to press the paper edges downwardly in the stack. Pinch rollers for driving the paper include low inertia drive rollers formed of a relatively low density plastic material with a pair of idler rollers. To improve stacking, ironing tractor idler rollers iron the tractor perforations, and chains orient the catenary stacking movement. | ||||||

| 123 | Image forming apparatus having a movable separator for separating a recording medium from a feeding belt | US505146 | 1995-07-21 | US5764264A | 1998-06-09 | Yasuyuki Takanaka |
| An image forming apparatus having a movable separator to separate a recording medium from a feeding belt includes feeding structure for feeding an attached recording medium in a predetermined feeding direction. Image forming structure receives the recording medium from the feeding structure and forms images on the received recording medium. The separator is located on a downstream side of the image forming structure, and separates the attached recording medium from the feeding structure in a direction which is angled from the predetermined feeding direction. The separator moves to push the recording medium from a non-recording face thereof to a recording face thereof while the recording medium is stopped during intermittent feeding to cause even separation of the recording medium from the feeding structure. | ||||||
| 124 | Double-sided printing system for continuous forms | US353126 | 1994-12-09 | US5548390A | 1996-08-20 | Eiichi Sugisaki; Mitsuhiro Ino; Masato Nagayama |
| An intermediate buffer device for absorbing the difference in paper feeding speed between first and second printers is disposed therebetween. The first printer prints on a first surface of continuous forms in accordance with the top-surface printing data input from a host apparatus, and the second printer prints on the second surface of continuous forms in accordance with the back-surface printing data input from a host apparatus. A detecting portion detects the amount of retention in the intermediate buffer device. A printer controller stops printing and paper feeding by the second printer when the amount of retention falls below a first set value L1 and stops paper feeding and printing by the first printer when the amount of retention exceeds a second set value L2. | ||||||

| A thermal printer of the type printing an image on a printing paper wound in the form of a roll. Curling of the printing paper wound in the roll form occurs when the thermal printer is placed in its standby mode over more than a predetermined period of time while the printing paper is held between a platen roller and a thermal head. In order to prevent curling of the printing paper, the printing paper is rewound when the standby mode lasts over more than the predetermined period of time. | ||||||
