摘要： A forms feed tractor belt includes drive members molded around a thin, flexible band at longitudinal intervals. To make the belt, slots are first punched at longitudinal intervals in at least one side of the flexible band. Drive members are then molded around the band at the slots except for at least one drive memberless interval at each end of the band. The ends of the band are overlapped so that the slots of the drive memberless intervals coincide. Final drive members are then molded around the slots of each pair of coincided drive memberless intervals to complete the endless tractor belt.

摘要： There is disclosed herein a forms feed tractor mechanism having a belt with pins and driving elements extending threrethrough. The pins are adapted to engage perforated holes along the edge of a recorded medium. Driver means are provided for rotating the belt and pins and thereby rotate the engaged medium. Also, there is provided a spring tensioner for maintaining tension on the belt. The tractor includes a door which is rotatably snapped fitted into the housing of the tractor and maintained above the plane of the record medium by an extension on the lower surface thereof. The belt and pins are constructed by molding the pins around the belt side so that the belt is below the feeding surface of the tractor mechanism upon which the paper rests.

摘要： The present printer is adapted to be easily equipped with removable and interchangeable paper feed modules of several different types. Each of the paper feed modules is specifically adapted to feed a particular type of paper through the printer and each is easily replaceable by the purchaser of the printer to be used for feeding a specific type of paper therethrough. The printer is provided with a main frame including a pair of side support members and an elongate platen extends between the side support members and is fixed at opposite ends thereto. Three different types of removable and interchangeable paper feed modules are illustrated in the present application and each includes a pair of elongated end plates with a paper moving mechanism supported intermediate the elongated end plates. The end plates are each provided with a pivoted mounting member adapted to engage a guide slot in the main frame side support members and a mounting notch is provided in the midportion of each of the end plates to swing into clamping engagement with the platen when the elongated end plates are pivoted about the pivotal axis of the mounting members so that the removable paper feed module may be inserted into the working region of the printer and on the side of the platen opposite the printhead and pivoted toward the printhead to bring the clamping notch into clamping engagement with the platen.

摘要： A user replaceable printer ribbon shield of simple design is provided for use in high speed matrix printers utilizing continuous forms. The shield is detachably mounted. During printing, the shield prevents outfolds in the forms from catching on the ribbon and prevents ribbon ink from migrating to the forms. It moves with the platen slightly away from the matrix print head when the machine is idle for at least a preset period of time. This causes the ribbon to move away from the ends of the print wires in the matrix print head to keep print wire lubricatng oil from migrating to the ribbon.
摘要翻译：提供简单设计的用户可更换打印机带状屏蔽，用于使用连续形式的高速矩阵打印机。屏蔽可拆卸地安装。在打印过程中，防护罩可以防止色带中出现的褶皱变形，从而防止色带墨水转移到表格上。当机器空闲至少预设一段时间时，它随着压板稍微离开矩阵打印头而移动。这使得色带从矩阵打印头中的打印线的端部移开，以保持打印线润滑油不会移动到色带。

摘要： A ribbon positioning mechanism comprises a ribbon cartridge, a nosepiece, a stepper motor and flexible ribbon guides connecting the ribbon cartridge to the nosepiece. The nosepiece has two side members connected by a bridge, one of which has a downwardly extending leg. A rack located on the bottom of the leg engages a pinion attached to the stepper motor for lifting the nosepiece into a desired position. A ribbon, having a plurality of parallel color bands, passes from the ribbon cartridge via the flexible ribbon guides and through the nosepiece where it is aligned with a print head. The nosepiece freely slides on vertical guide posts attached to a print head carrier and printer logic controls the stepper motor to align the desired color band with the print head.

摘要： There is disclosed herein a dot matrix tilting print head assembly in which the print head is rotatably mounted in a frame. A solenoid is provided for rotating the print head a controlled distance so that printing occurs between previously printed dots. A pin extending from the print head is positioned into a larger diameter hole in the frame for controlling the distance to be one half of the center-to-center distance between printed dots. This entails maintaining very low tolerances for the mechanically moving parts. In addition, there is provided support members for allowing the removal of the print head alone from the frame means.

摘要： An improved mechanism is provided for preventing long-term oil contamination of the print ribbon in a wire matrix printer. In the event that the print ribbon has an excess of oil thereon, it will cause the printed characters to be alternatively too light or too dark thereby reducing the print quality on the document. The print head of the wire matrix printer is operated to an idle or at rest position when printing is not being effected, a camming mechanism retracts the print head away from the platen and document. When this occurs, a stationary member on the printer carriage engages the ribbon and moves it away from contact with the print head in the vicinity of the apertures through which the print wires are guided for printing. With the ribbon moved away from the apertures, the lubricant oils on the print wires do not flow on to the ribbon. The retracting of the print head away from the platen and document by the camming mechanism also permits the easy insertion of new forms into the printer.

摘要： In a printing system employing a spliced endless print ribbon, an opening is provided in the ribbon adjacent the splice to enable sensing of the approach of the splice to the print station. Printing is suspended as the splice passes the print station to avoid undesirable printing quality and damage to the splice. The same sensing means detects lack of ribbon movement, indicative of a ribbon jam, to suspend printing and ribbon drive.
