Handheld printer

Abstract

The invention discloses a handheld printer, and relates to the technical field of printers. The handheld printer comprises a machine shell, an ink box, a main roller, a main control board and an FPC device, wherein the FPC device comprises a flexible circuit board; the main control board and the flexible circuit board are both arranged in the machine shell, the ink box can be placed inside the machine shell, the flexible circuit board is electrically connected with the main control board, and the flexible circuit board can be electrically connected with the ink box; a printing driving module,a position sensor module and an ink box recognition module are integrated on the flexible circuit board; and the main roller is connected with the machine shell, the main roller is connected with a magnet, and the magnet is opposite to a Hall element inside the position sensor module. According to the handheld printer, the printing driving module, the position sensor module and the ink box recognition module are integrated on one flexible circuit board, so that the space utilization rate is improved, the wiring number can be reduced, the assembly complexity is reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of printers, in particular to a handheld printer. Background technique [0002] Currently, hand-held small printers are used in more and more scenarios due to their light weight, small size, portability, and convenient printing. A traditional hand-held small printer includes a housing in which a main control board, an ink cartridge and a circuit board are arranged, and the circuit board is respectively connected with the main control board and the ink cartridge to drive the ink cartridge for printing. [0003] In the prior art, a circuit board is usually used as the carrier of the position sensor module and the ink cartridge identification module, and is connected to the main control board through wiring. [0004] However, due to the limitation of the internal structure of the printer, the position sensor module and the ink cartridge identification module need to be installed in different positions,...

AI Technical Summary

Problems solved by technology

[0004] However, due to the limitation of the internal structure of the printer, the position sensor module and the ink cartridge identification module need to be installed in different positions, so only multiple circuit boards can be installed to meet the installation requirements, and the circuit boards are connected to the main control board through wiring. The increase in the number of circuit boards leads to an increase in the number of wiring inside the printer casing, and the lines are mixed and chaotic. Mistakes are prone to occur during assembly and wiring, resulting in hardware damage and affecting production efficiency.
