摘要： A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system has a drive gear which slips against a toothless portion of a driven gear while paper is being fed through the printer for printing by a print head. When printing stops, the drive gear reverses its rotation, causing the driven gear to engage the drive gear. A cutter blade is controlled by the driven gear, with the blade cutting off the paper as the drive gear is in reverse rotation. After the paper is cut, the drive gear resumes its forward rotation, rotating the blade away from the paper. After the blade has been rotated, the drive gear continues to turn, but slips on the toothless portion of the driven gear. Friction losses are minimized as the energy lost as friction is low and full torque is applied to both cutting and opening rotations of the cutter blade.

摘要： A printer mechanism includes a single motor turning a system drive gear in a paper feeding direction, and in a cam driving direction, opposite the paper feeding direction. When the system drive gear is turned in the paper feeding direction, a paper feeding spring clutch drives a paper feed roll with the system drive gear. When the system drive gear is turned in the cam driving direction, a drive cam is driven by a cam driving spring clutch. The drive cam has a first surface driving a moving knife blade across a stationary knife blade in a cutting direction, and in a return direction opposite the cutting direction. With this movement in the cutting direction, the moving knife is held against the stationary knife blade, and, with movement in the return direction, the moving knife is moved away from the stationary knife blade, by means of a second surface of the drive cam. Provision is made to allow the cam driving clutch and cam to return to an original configuration after an event in which knowledge is lost of the operating mode and position of the mechanism.

摘要： A document feed roller opening mechanism and a method for operating that opener provide efficient and reliable operation. In the document feed roller opening mechanism, a print head transport motor is used to open the document feed rollers. A carrier post is implemented to engage a document insert lever when the print head carrier is positioned over a cam on the document insert lever. Thus engaged, the document insert lever rotates to pull a left end of the document insert pressure roller. The left end of the document insert pressure roller slides towards a front of the printer and a right end pivots slightly in a right frame. A spring implemented therein compresses as the document insert pressure roller moves away from a stationary document insert feed roller. This spring provides pressure to the document insert feed roller when the rollers are together. With the document insert feed rollers open, one may easily slide a document in from the side of the printer.

摘要： A thermal printing station includes a split rotary platen, which is driven in rotation to move a paper web across a thermal print head held against the split rotary platen. The split rotary platen includes a motor-driven shaft, a main platen roll driven by the shaft, and a platen roll extension, which is slidable along the shaft between a first position, in which the platen roll extension is engaged with to turn with the main platen roll, and a second position, in which the platen roll extension is disengaged from the main platen roll, being allowed to remain stationary due to friction forces arising from contact with the thermal print head. The first position is used for printing on a wide paper web, while the second position is used for printing on a narrow paper web, which extends only along the main platen roll. A clip is attached to the shaft to hold the platen roll extension in the first or second position.

摘要： A computer display includes a pivotally mounted upper housing having a display screen, a brake used to retard pivoting motion of this upper housing, and a release mechanism for releasing the brake so that the upper housing can be freely moved. The display screen is preferably a touchscreen, which is touched to indicate a selection made by the user, with the brake resisting a tilting movement of the screen as it is touched. In a first version, two brakes are used to retard motion in both directions, with a single release wheel being turned in one direction to allow rearward motion of the upper housing and in another direction to allow forward motion of the upper housing. In a second version, a single brake is released by stopping motion of a release mandrel to unwrap a clutch spring. In a third version, two brakes, operating near opposite edges of the upper housing to stop downward movement of the upper housing, provide a particularly stiff mechanism for mounting the upper housing, and are simultaneously released by turning a knob to pivot a shaft.
