摘要:
A device for selecting print characters of endless printing bands in a printer that, when restricting the rotation of endless printing bands for preventing fouling of display characters, can avoid excessive rotational force from acting on the endless printing bands and enable selection of desired print characters in cases where, for example, the endless printing band is for full-periphery printing or half-periphery printing. Both half-periphery printing capability and full-periphery printing capability can be implemented by providing regulating blocks capable of rotation as print pressure bearing members, the device is characterized in that selection of print characters is restricted by engagement of drive projections of an endless printing band and an elastic section of a movable stopper member and that, in the case where no drive projection engages with the elastic section, selection of print character is made possible and a regulating block receives the print pressure on the print character.

There is disclosed an endless flexible printing band and method of making such printing bands. A wide endless band having columns and rows of raised printing characters is molded onto a sheet having columns and rows of visually readable characters corresponding to the printing characters. Following molding, the wide band is slit into a plurality of printing bands.

A pre-ink die-plate dater includes a casing having a bolt transversely extending therethrough to which at least one disk member is mounted, a die-plate rotatably reeved around a first shaft of the disk member and a second shaft, a bottom board pivotally connected to an underside of the casing and having an oblong opening defined therein so as to receive a stamping face of the die-plate therein. An adjusting member is disposed between the casing and the bottom board and connected to the bottom board by two screws. A distance between the bottom board and the adjusting member is adjusted by rotating the screws.

A printing mechanism is described comprising a plurality of type carriers (12, 34) which on their outer peripheral face carry in one region printing types and in another region indicator types (44). The printing types can be brought into a printing position by turning the type carriers (12, 34). A setting means (32, 20, 24) including an actuating knob (32) can be brought into a drive connection with each of the type carriers (12, 34) for rotation thereof. Stop means (100, 102, 104, 106, 110) limit the turning travel of the type carriers (12, 34). Detent elements (96) hold the actuating knob against rotation relative to the type carrier (12, 34) which is in drive connection with the setting means (32, 20, 24), with a detent moment governed by the spring hardness of the detent elements. The spring hardness and thus the detent moment are determined so that when a moment is applied greater than the detent moment, rotation is permitted between the actuation knob and the type carrier, and when a moment is applied, there is no relative rotation between the actuation knob and the type carrier, and the type carrier is turned.

A type band for a printer comprises a track of marks to be scanned (timing marks) at least one of which is obliquely positioned relative to its adjoining marks. The centers of all marks are equidistantly spaced. When the horizontally moving type band is vertically displaced, the time spacing of the scanning signal of the obliquely positioned timing mark is changed over the scanning signal of its adjacent timing mark. The magnitude of the vertical displacement of the type band is derived from the change in this time spacing. The displacement data thus obtained permit compensating for the vertical displacement of the type band (using, for instance, a stepper motor).
摘要:
A type arrangement data editing apparatus in which type arrangement data from a type carrier is automatically edited in accordance with the carrier set carried by the type carrier. A first area of a ROM stores the basic type arrangement data for a plurality of basic character sets. A second area of the ROM stores replacement data which is replaced for specific symbols in the basic character sets, and the start addresses of the type arrangement data for each set. An identifier identifies which character set and which replacement data are carried on the type carrier. A microprocessor stores a program for retrieving the respective type arrangement data and inserting the replacement data therein. The data is sent to a RAM, where it is compared to input data to print a specific print symbol.
摘要:
An adjustable stamp is provided having at least one loop-shaped type ribbon guided by an adjustment wheel and a support strip, the type set for printing being disposed at the bottom side of the support strip, and a frame plate supporting a printing plate producing a permanent imprint and having a window through which the type disposed on the support strip projects. The frame plate is displaceably supported by means of guide strips leading into the interior of the housing of the stamp and is displaceable by means of a manipulating device connected to the guide strips.
摘要:
An endless printing band (1) consists preferably of rubber or synthetic rubber and in its production is cut from a hose-like blank by cuts extending along its edge. Said printing band (1) has in the one region of its outer side visually readable characters (3) and in an opposite region laterally inverted raised printable characters (5). In the region of the readable characters (3) on the inner side (11) of the printing band (1) inwardly projecting cams (6) are provided for the advance of the band while the inner side (7) of the region comprising the printable characters (5) is smooth. To nevertheless ensure at both band regions equal amounts of material for as uniform as possible shrinkage in the production of the printing band (1) in the region of the transport cams (6) on the outer side of the band (1) remote from the cams (6) recesses (9) are provided whose lowermost point (10) lies beneath the center of the band (1) between the cams (6) and preferably substantially at the height of the inner side (11) of said band region between the cams (6). As a result, at the run (2) of the band (1) having cams (6) and the likewise raised readable characters (3) so much material is saved that the material accumulation of the two band regions or runs (2 and 4) is substantially the same and this gives the same shrinkage in the production. (FIG. 1).
摘要:
A printing apparatus is provided which utilizes rolling pressure contact for printing, and includes a plurality of sets of serially arranged character elements mounted for movement on the external surface of a printing drum. Movement of the sets to place a desired character into printing position is accomplished by controlling the speed of a motor driving a pulley connected by cable to a given character set, relative to the speed of a motor driving the printing drum in rotational movement.
摘要:
A strip assembly for a printing device having an endless type band frictionally driven by drive and idler pulleys between print hammers and a platen comprises a wear strip and wiper strip attached together at a common end. The wiper strip has a wiper portion extending from the point of attachment which terminates in a scraper edge. A retention device mounted in proximity with the drive pulley comprises means connectable to the common end to hold said wear strip under tension and said wiper strip in spring loaded condition with the scraper edge in contact with the drive surface of the drive pulley for cleaning wear strip residue and other deposits from the pulleys and the type band.
