TH51402A - A device for selecting the print character of a ribbon-less printer? - Google Patents

Abstract

The DC60, in its design, provides a mechanism for selecting the print character of an endless print bar in a printer. By limiting the rotation of the endless print bar 7 to prevent character smearing (7B), excessive rotational force on the endless print bar 7 can be avoided, allowing for the selection of the desired character (7A). This is useful in cases where the endless print bar 7 is used for full-edge or half-edge printing. Focusing on the fact that both half-edge and full-edge printing capabilities can be achieved by providing a rotating control frame 6 as the printing pressure support, the device is unique because the selection of character (7A) is limited by the connection of the endless print bar 7E drive extension and the 14B flexible extension of the character assembly. The movable stop 14, and in the absence of the 7E drive extension connected to the 14B flexible section, character selection 7A is made possible, and control frame 6 receives the printing pressure on character 7A. In arranging a device for character selection of the endless print bar in a printer, when limiting the rotation of the endless print bar 7 to prevent smudging of character 7B, it is possible to avoid excessive rotational force acting on the endless print bar 7, and thus enable the selection of the desired character 7A. In various cases, such as when the endless print bar 7 is used for full-edge printing or half-edge printing, from the focus on the fact that both half-edge and full-edge printing capabilities can be achieved by providing a rotatable control frame 6 as the printing pressure support part, such a device will have... Due to the nature of character selection, 7A is limited by the attachment of the 7E drive extension of the endless print bar 7 and the 14B escaping section of the 14 movable stop section. In the absence of the 7E drive extension attached to the 14B escaping section, character selection of 7A is enabled, and control frame 6 applies the printing pressure to character 7A.

Claims (15)

1. Character selection device for an endless print bar in a printing press with at least one endless print bar formed by multiple characters spaced evenly apart. This device is positioned between the selector wheel and the printing pressure support, which is mounted to the printing press frame. The device allows the selection of the desired character on the endless print bar. The endless print bar character selection device in this printing press is unique because it comprises a movable stop with a control shaft for fitting the selector wheel and a return mechanism on the side of the printing pressure support, located between the selector wheel and the printing pressure support; a stop support that braces against the return mechanism of the movable stop to control its movement; a drive projection formed on the inner edge surface of the endless print bar that is fitted to the selector wheel; and a control frame that is fitted to this drive projection of the endless print bar. It will have the ability to rotate forward and backward, along with the movement of the endless print bar, to position the printed characters at the printing location where those positions will receive the appropriate printing pressure. When the drive extension can be fitted with the escaping part of the movable stop, the fitting between the drive extension and the escaping part, along with the movement of the endless print bar, limits the selection of printed characters of the endless print bar while still allowing slight movement of the movable stop. And when the drive extension of the endless print bar is not fitted with the escaping part of the movable stop, the selection of printed characters along with the movement of the endless print bar is enabled, and the control frame is made capable of receiving printing pressure on the printed characters. 2. Character Selection Device for Endless Print Bars in Printing Presses with at least one endless print bar formed by multiple characters spaced evenly apart, provided between the selector wheel and the printing pressure support, which is mounted to the printing press frame. This device enables the selection of the desired character for the endless print bar. The character selection device for endless print bars in printing presses is unique because it comprises a movable stop with a control shaft for fitting the selector wheel and a return mechanism on the side of the printing pressure support, located between the selector wheel and the printing pressure support; a stop support that braces against the return mechanism of the movable stop to control its movement; a drive projection formed on the inner edge surface of the endless print bar that is fitted to the selector wheel; and a control frame that is fitted to this drive projection of the endless print bar. It will have the ability to rotate forward and backward, along with the movement of the endless print bar, to position the printed characters at the printing location where those positions will receive the appropriate printing pressure. The assembly between the drive and return parts, along with the movement of the endless print bar, causes slack in the endless print bar to allow for free rotation of the selector wheel. 3. The character selection device for the endless print bar in the printers under either Patent 1 or 2 is unique because the elongated guide window for sliding assembly into the movable stop is formed in the movable stop part, allowing the movable stop to be mounted onto the stop, and the beveled anti-defect surfaces of the printer housing assembly and the beveled anti-defect surfaces of the stop part assembly are formed on the stop and the elongated guide window for sliding assembly. 4. The character selection device for the endless print bar in the printer under Patent 3 has a special characteristic because such printer will have a stage one printing section and a stage two printing section. In the stage one printing section, the beveled defect-preventing surface of the first frame assembly is formed on the printing frame, and the beveled defect-preventing surface of the first stop assembly, which is capable of fitting onto the said beveled defect-preventing surface of the first frame assembly, is formed on the movable stop of that section. In the stage two printing section, the beveled defect-preventing surface of the second frame assembly is formed on the printing frame, and the beveled defect-preventing surface of the second stop assembly, which is capable of fitting onto the said beveled defect-preventing surface of the second frame assembly, is formed on the movable stop of that section. Each stage one printing section and stage two printing section will have An endless print bar is formed with protruding sections, a movable stop piece mounted on the printer chassis, and a stop support piece. 5. The character selection device for the endless type ribbon in the printer under either Patent 1 or 2 is unique because such control frame is interchangeable with a character support that can be permanently mounted on the printer chassis. 6. The character selection device for the endless type print bar in the printer under Patent 5 has a unique characteristic because the character support base is constructed from a material that is harder than the printer housing. 7. The device for selecting the character of an endless tapered tape in a printer under either Patent 5 or 6 is special because the endless tapered tape has a flat outer edge that is not formed by the character and a flat inner edge that is opposite the character and fits onto the character receiving base. 8.
