摘要： A dot matrix printing apparatus including a carriage (20) having mounted thereon a coupling device (42) co-operating with an endless toothed belt (36) for moving the carriage (20) in a reciprocating manner. An arcuate member (46) is provided having a surface complementary to the teeth on the belt (36) for engagement therewith. A pair of guide members (44) extend from the carriage (20) and are spaced from the surface of the arcuate member (46) to define a guide path therebetween. Each of the guide members (44) has a respective projection (52) which extends under the guide path and acts as a support and retaining member for the belt (36).

摘要： A printer (10) for printing on record media having different thicknesses utilizes a platen supporting arm assembly (30) which is pivotable to move the platen (26) towards and away from a print head (24). Another supporting arm assembly (60), also pivotable, is provided to carry a record media feed roller (36) and is interconnected with the platen supporting arm assembly (30) by means of a pin and slot arrangement (90, 82) to effect a substantially equal gap between the platen (26) and the print head (24) and between the feed roller (36) and a pressure roller (62) cooperating therewith. A camming means (90) is rotated to bring about movement of the supporting arm assemblies (30, 60) into printing position and a latching means (116) is connected with the camming means (90) and rotated thereby to maintain the platen supporting arm assembly in printing position.
摘要翻译：用于在具有不同厚度的记录介质上打印的打印机（10）利用压板支撑臂组件（30），所述压板支撑臂组件可枢转以使压板（26）朝向和远离打印头（24）移动。提供另一个也可枢转的支撑臂组件（60），用于承载记录介质进给辊（36），并通过销和槽排列（90,82）与压板支撑臂组件（30）互连以实现压板（26）和打印头（24）之间以及进给辊（36）和与其配合的压力辊（62）之间的基本相等的间隙。旋转装置（90）旋转以使支撑臂组件（30,60）移动到打印位置，并且闩锁装置（116）与凸轮装置（90）连接并旋转，从而保持压板支撑臂组装在打印位置。

摘要： A slip/receipt printer (10) is provided with a separator bracket (150) attached at one edge thereof to a forms compensating arm (30) in cantilever manner. Guide means (176, 178) are provided on the separator bracket (150) to provide a precise path for receipt paper (116). The separator bracket (150) is biased by magnetic means (164) towards the arm (30) for supporting the receipt paper (116). A slip or form (12) is inserted into the printer (10) on the top surface of the separator bracket (150).
