Duplication dynamics automatic adjustment structure assembly of stylus printer

Abstract

The invention discloses a duplication dynamics automatic adjustment structure assembly of a stylus printer. The duplication dynamics automatic adjustment structure assembly of the stylus printer comprises a support and a paper-thickness regulating shaft of an eccentric shaft, wherein one end of the paper-thickness penetrates through the support, and then a paper-thickness slection lever is fixedly installed at a tail end of the paper-thickness regulating shaft. The paper-thickness selection lever is in a sector structure, and a surface of the selection lever is divided into an inner sector shape and an outer sector shape. File position teeth are arranged on one end surface of the inner sector shape along diameter direction of the inner sector. Blocking needles locked in the file position teeth are arranged on the support. A U-shaped photo-electricity sensor is installed on the end surface of the support nearby the paper-thickness selection lever. Blocking slices capable of sheltering beams of the U-shaped photo-electricity sensor are arranged on the paper-thickness selection lever. A duplication dynamics state of the automatic adjustment stylus printer is capable of abandoning a duplication dynamics adjustment manner of manually regulating the duplication dynamics through a panel press button in the traditional technology. The duplication dynamics automatic adjustment structure assembly of the stylus printer is simple in structure, reasonable and compact, saving in bill material and high in printing efficiency.

Description

technical field [0001] The invention relates to a structural assembly for automatically adjusting the copying strength of a dot matrix printer. Background technique [0002] Bills often need to be copied and printed in multiple copies. Dot matrix printers play an irreplaceable role in the peripheral application market of specific industries due to their multi-layer copying characteristics. The copying ability of dot matrix printers refers to the printer. The ability to print up to "several pages" on carbon printing paper, the duplication ability of a dot matrix printer is related to the strength with which the product's printing needle hits the printing medium. Therefore, for printing media of different thicknesses, the requirements for the impact force of the printing needle on the printing medium are different, especially for multiple superimposed copy printing, the required impact force is relatively high, so that the data of each bill is clear and unambiguous. In the tr...

Problems solved by technology

In the traditional technology, the copying strength of dot matrix printer needs to be manually adjusted by the user through the panel buttons. Every time for printing media with different thicknesses, the user must manually adjust the copying strength through the panel buttons, which increases the cumbersome operation. Once the customer forgets to manually Adjusting the copying strength will cause the printed bills to be unclear and waste materials; at the same time, the dot matrix printer needs to be equipped with special panel buttons and corresponding control circuits, which increases the structural complexity of the dot matrix printer. Certain restrictions, aesthetics are affected
