Handheld Laser Scanner

Abstract

The invention discloses a handheld laser scanner. The handheld laser scanner comprises an engine part and a holding part; the engine part is fixed at the upper end of the holding part; a circuit board is arranged in the holding part; an optical sensor and a control circuit are arranged on the circuit board, and are electrically connected; a laser emitter and a reading lens are arranged in the engine part; the laser emitter is electrically connected with the circuit board in the holding part; the engine part further includes a laser scanning window inwards recessed; an ash removing mechanism for removing dust on the laser scanning window is arranged at the upper end of a scanning head of the laser scanning window; and an up-down sliding mechanism for driving the ash removing mechanism to operate is arranged on the front end side surface of the laser scanning window. The handheld laser scanner has the following beneficial effects thatautomatic ash removal is realized; the ash removing mode is convenient and flexible; the life cycle of the laser scanner can be prolonged; the fault rate of the laser scanner is largely reduced; the working efficiency is improved; the loss is reduced; and the feasibility is high.

Description

technical field [0001] The invention relates to a scanner, in particular to a hand-held laser scanner. Background technique [0002] The laser scanner is used to record the price, name, item number and other information of the commodity, and scan the barcode optically, which can quickly read the data, reduce a lot of time that originally required manual data entry, and save management and personnel costs. At present, the scanners for reading and barcodes can be divided into two types: fixed and handheld according to the operation mode. Among them, the handheld barcode scanner is a relatively economical and convenient device for reading barcodes. When the scanner reads the barcode, the positional relationship and angle between the scanning head and the barcode label are closely related to whether the barcode data can be read correctly and quickly. [0003] The scanning head of the laser scanner in the prior art is designed with a concave structure, and more dust will adhere ...

AI Technical Summary

Problems solved by technology

[0003] The scanning head of the laser scanner in the prior art is designed with a concave structure, and more dust will adhere to it during continuous use, so that the laser scanning head will not be able to scan effectively during the scanning process. As a result, the laser scanner will be limited after a period of use, and in supermarkets and other large manufacturers or places where laser scanners are used, once the scanning fails or the barcode cannot be scanned, it will directly affect the work and lead to stand still, cause loss
