摘要: Systems for discriminating among a plurality of type carriers differing in number of characters and pitch of characters are disclosed. In one circuit, the type carrier is provided with synchronizing marks and discrimination marks in addition to the usual type character marks. The synchronizing mark is located at the beginning of a set of characters, and the discrimination mark is located a predetermined distance from the synchronizing mark according to the number of characters and pitch of the particular type carrier. This distance is determined by counting type character marks. In another circuit, one or more discrimination marks are provided between type character marks at the beginning of a set of characters. The number of discrimination marks indicates the number of characters of the particular type carrier. In either circuit, a counter of only a few stages and a simple decoding circuit are all that are required to carry out the discrimination operation.

摘要: A dot printer in which vibration is eliminated without the use of a separate counterweight. The printer includes first and second hammer banks each holding a plurality of dot printing elements. The first and second hammer banks are spaced apart from each other a predetermined distance in the direction in which a printing sheet passes. A motor and oppositely-phased drive cams reciprocate the two hammer banks in opposite directions parallel to a dot printing direction.

摘要: To adjust the posture of a sheet being conveyed, movable checker members provided adjacent to the conveyance path for the sheet are once driven in the direction of conveyance of the sheet before the members touch the sheet and are subsequently decelerated, the members being caused to abut against the front end of the sheet during the deceleration, thereby checking the sheet and thus correcting any skew thereof. Further, for positioning the sides of the sheet, the sheet is taken out of a hopper by way of a separating device and is guided and fed in such a manner that its front corner will not be caused to abut against a side registration guide, and subsequently the sheet is conveyed toward the guide by way of obliquely extending conveyer belt devices and one side of the sheet is brought into contact with the guide for positioning after a front corner of the sheet has passed at least the edge of the guide.

摘要: A printing apparatus comprising a type carrier to travel along a print line on a printing paper, a plurality of printing hammers to be selectively driven to strike the printing paper against an inking ribbon and the inking ribbon against a platen in front of the inking ribbon, and a support member supporting the type carrier, inking ribbon and platen thereon, wherein the support member is movable between a position holding the type carrier, inking ribbon and platen in positions capable of performing printing operation but intercepting the line of sight between the print line and the operator's eyes and a position holding the type carrier, inking ribbon and platen in inoperative positions but providing an unobstructed line of sight from the operator's eyes toward the print line for enabling the operator to clearly view the printed information along the print line.

摘要: In a perfecting printing machine, a switch-back mechanism moves backwardly each sheet delivered out of the printing section, and a switching gate provided immediately after the switch-back mechanism selects a first sheet path to return the sheet whose one side has been printed to the printing section and a second sheet path so that the sheet whose both sides have been printed is delivered to the stacker after being moved backwardly by the switch-back mechanism.

摘要: An upper cover for a line printer in which an upper cover hood can be easily opened forwardly to permit full maintenance of the printing mechanism. The upper cover hood is pivotally coupled through a rear hinge holder to a forwardly-extending support member via a balance holder. A balancing mechanism is pivotally coupled at one end to the balance holder. At the front end of the support member a hook member is hingedly attached, the other end of which is adapted to be swung into position and coupled to a pin which is rigidly coupled to a side wall of the upper cover hood. A cushioning packing is disposed along the front edge of the upper cover hood.
