Receipt printing machine

Abstract

The invention provides a receipt printing machine. The receipt printing machine comprises a paper bin, a first rolling rotary shaft, a second rolling rotary shaft, a paper feeding nozzle, a printing machine head, a cutter device, a paper transferring device, a paper outlet nozzle and a paper withdrawing opening. Printing paper is stored in the paper bin, and the paper bin is obliquely arranged relative to the paper feeding nozzle and located above the paper feeding nozzle. The printing paper sequentially passes through the first rolling rotary shaft and the second rolling rotary shaft to be conveyed to the paper feeding nozzle and then is printed by the printing machine. The cutter device cuts the printed printing paper into small receipts, the small receipts are transferred to the paper outlet nozzle through the paper transferring device to be discharged, and when not taken away within the preset time, the small receipts are transferred by the paper transferring device from the paperoutlet nozzle to the paper withdrawing opening to be sent out. The receipt printing machine ingeniously utilizes the space, is small in size, has the functions of automatic paper transferring and automatic recovery, and is easy and convenient to use.

Description

technical field [0001] The invention relates to the field of printer equipment, in particular to a self-service small ticket printer. Background technique [0002] Conventional small ticket printers use roll-feed or flat-in and flat-out. The diameter of the paper roll of the roll-type invoice is limited by the space of the paper warehouse and the bearing strength of the paper shaft. If you choose a super-large paper roll to save the number of paper changes , the paper cutting force is forced to increase, the cutter wears faster, and the life of the printer is reduced; the flat-in flat-out type requires a large space for the paper warehouse, which does not conform to the design concept of the ultra-thin cabinet structure of self-service equipment; this patent adopts "S "Type paper feeding, which effectively solves the above problems, and also adds functions such as automatic paper feeding and automatic paper recycling of the printer.
