摘要： A point of sale (POS) receipt printer that includes a selective release mechanism that converts the printer into a check account verifying machine. The conversion mechanism magnetizes and selectively reads the account and bank information from existing magnetic characters on a check presented face-up to the receipt printer. The mechanism includes a magnet to magnetize the characters and a read head to read and analyze the signal waveform from each character. The check is pressed up against the read head and the magnetic characters are read only after the printing carriage of the receipt printer has moved to a dead zone within the printer housing.

摘要： A printer has a bi-directional stepper motor that drives an endless toothed belt which is secured to a print head carriage for driving the carriage back and forth across the printer along a line of printing. A timing strip is molded integral with the frame of the printer and positioned under the print head carriage. An optical sensor of the light emitting diode and phototransistor type is secured to the underside of the carriage and positioned to straddle the timing strip as the carriage is driven back and forth across the printer. The printer controller uses timing strip/sensor signals to place the print head in a home position when the printer is turned on and also when the print head has been moved from an operating position, e.g. in the case of changing a ribbon. The timing strip/sensor signals are also used to detect a carriage jam condition.

摘要： The present invention features a cutting mechanism for a receipt-printing machine, which has paper dispensed from a paper-supply roll. The cutting mechanism has a "v"-shaped, guillotine blade that is held in a blade holder. The blade is driven via the blade holder against a stationary blade and into cutting contact with a paper web containing receipt indicia. The paper web is dispensed from a paper-supply roll located within the printer. A displaceable cover is provided to allow for convenient paper loading and, occasionally, paper jam clearing. There is a blade guide which has side mountings for guiding at least one end tab of the guillotine blade into perpendicular contact with the paper web. The guillotine blade is driven through the blade guide into cutting contact with the paper by a drive cam. The drive cam rotatively engages the blade holder, providing the blade with a forward thrust. The cam is driven by a motor-driven gear train that has a timing gear. The rotating timing gear activates a switch after every complete rotation, which terminates power to the motor, thus allowing a single rotation for the drive cam and, hence, a single cutting cycle. The guillotine retracts from the blade guide under the influence of spring biasing, and is then ready for the next cutting cycle. The guillotine blade is retracted to a remote position within the printer.

摘要： A device for connecting a toothed timing belt to a printhead carriage includes an arcuate member and a pair of posts extending downwardly from the carriage. The arcuate member includes a generally concave surface and a generally convex surface which is complementary to the toothed configuration of the timing belt. The posts are provided with angled surfaces located adjacent to the convex surface of the arcuate member to define passageways into which the belt is placed. Ledges at the lower ends of the posts prevent unintended slippage of the belt from the device when the belt is not under tension.

摘要： A dot matrix print head has a heat sink substantially surrounding the head for dissipating heat therefrom. A print head carriage includes a pivot or bearing assembly on one side of the print head and includes a bail type clamp pivoted on the carriage on the other side of the print head. The arrangement allows the heat sink to swing from a covered print head operating position to an uncovered position for servicing or for removing the print head.

摘要： A ribbon is driven past the printing station of a printer only when the print head is moved in the right-to-left direction across the printer. An endless timing belt causes rotation of a gear pulley that is in mesh with an idler gear. The idler gear is supported on a pair of projecting fingers of a plate that is swingable on the center of the gear pulley. The idler gear is responsive to the direction of rotation of the gear pulley through a drag effect of the projecting fingers with the bottom surface of the idler gear.

摘要： A mechanism for compensating for different thicknesses of record media at a printing station utilizes a platen supporting or carrying assembly which is pivotable to move the platen toward the print head. Another supporting assembly, also pivotable, is provided to carry a record media drive roller and is interconnected with the platen supporting assembly by means of a pin and slot arrangement to effect a substantially equal gap at the platen-print head and at the pressure roller-drive roller. A first cam member is rotated to engage with and to swing the platen supporting assembly into printing position and a second cam member is connected with the first cam member and rotated thereby to maintain the assembly in printing position.

摘要： A printer for negotiating transactions at the point of sale in retail establishments. The POS printer includes a selective check reading mechanism that converts the receipt printer into a check reader. The mechanism includes a magnet to magnetize magnetic characters on a check and a read head to read and analyze the signal waveform from each character. The check is pressed up against the read head and the magnetic characters are read only after the printing carriage of the receipt printer has moved to a dead zone within the printer housing. In the dead zone, a tab, riding on the printing carriage, releases a spring-biased pivot arm. The pivot arm becomes free to pivot, thus releasing a spring-biased plunger, the face of which, in turn, forces the check and its indicia against the read head.

摘要： A new paper loading system is featured with a convenient drop-in paper loading and a full slip path in a receipt printer. The paper is dropped into a paper receiving bucket disposed in the central portion of the printer. The paper is fed from the bucket; and thereafter, a receipt is printed. Then, the paper is cut to the appropriate receipt length. A slip path is also provided for insertion of a single or multi-part form used for credit or check validation. The relative position of the slip path would normally interfere with the drop-in loading of the paper supply roll into the bucket. The system allows the fixed blade assembly to support a slip path upon a rear surface thereof. The slip path is substantially parallel or adjacent to the paper receipt path, which passes between assemblies supporting a fixed blade and a movable, rotary blade. The fixed blade unlatches and pivots away from the rotary blade, thus opening the printer and exposing the paper loading bucket for access thereto. The design eliminates the previous interference of the paper path with the slip path.
摘要翻译：新的纸张装载系统具有便利的纸盒装载和收据打印机中的全滑动路径。将纸张落入设置在打印机的中心部分的纸容纳桶中。纸从桶中进料; 之后，打印收据。然后，将纸切割成适当的收据长度。还提供滑动路径用于插入用于信用或检查验证的单个或多部分形式。滑动路径的相对位置通常会干扰供纸辊进入铲斗的下落负载。该系统允许固定刀片组件在其后表面上支撑滑动路径。滑动路径基本上平行或相邻于纸张接收路径，该纸张接收路径在支撑固定刀片和可移动旋转刀片的组件之间通过。固定刀片脱离旋转刀片，从而打开打印机并露出纸张装载桶以便进入其中。该设计消除了纸张路径与滑动路径之前的干扰。
