Furthermore, a plurality of connecting clamp holes are formed in both sides of the cover body, and a plurality of connecting clamping blocks matched with the connecting clamp holes are arranged on both sides of the mounting cover.

The utility model also provides a bar code printer which comprises the paper detection mechanism.

The beneficial effects of the utility model are:

compared with the defects of the prior art, in the utility model, when paper is fed, paper passes through the paper feeding channel from the paper guide, so that the paper feeding length and the paper feeding gap of the paper are detected, wherein when the paper is small, the sliding mechanism can drive the sensor assembly and the paper feeding channel to move through the locking block, so that the sensor assembly moves to one end of the sliding mechanism and moves to the maximum locking distance; when the paper is great, slide mechanism drive the sensor module reaches the paper feed passageway removes slide mechanism's the other end moves minimum locking distance, and passes through spacing portion carries on spacingly, consequently, paper detection mechanism can control the paper feed passageway removes in order to adapt to the not paper of equidimension, makes paper detection mechanism have the advantage that can adapt to the paper size.

Furthermore, the two clamping plates are respectively matched with the clamping grooves, so that the sensor assembly is more stable when the sliding mechanism moves.

Furthermore, the mounting cover can be stably buckled on the cover body through the matching of the connecting clamping blocks and the connecting clamping holes.

Because the paper detection mechanism can be adjusted according to the size of the paper, the bar code printer has the advantage of being suitable for the size of the paper.

Detailed Description

As shown in fig. 1 to 6, in this embodiment, the present invention includes a housing 1, a paper guide 2 is disposed on the housing 1, a sliding mechanism 3 is disposed on the paper guide 2, the sliding mechanism 3 drives a sensor component 4 to move, a paper feeding channel 10 is disposed on the sensor component 4, one end of the paper feeding channel 10 is an open end, the other end of the paper feeding channel 10 is a limit end, a locking block 5 matched with one end of the sensor component 4 is disposed on the sliding mechanism 3, and a limit portion 6 matched with the other end of the sensor component 4 is disposed on the housing 1. The slide mechanism 3 drives the locking block 5 to move, so that the locking block 5 can move simultaneously with the sensor assembly 4, and because one end of the paper feeding channel 10 is an open end, and the other end of the paper feeding channel is a limiting end, paper can enter from the open end of the paper feeding channel 10 and is close to the limiting end of the paper feeding channel 10.

Compared with the defects of the prior art, in the utility model, when paper is fed, the paper passes through the paper feeding channel 10 from the paper guide 2, so as to detect the paper feeding length and the paper feeding gap of the paper, wherein when the paper is small, the sliding mechanism 3 can drive the sensor assembly 4 and the paper feeding channel 10 to move through the locking block 5, so that the sensor assembly 4 moves to one end of the sliding mechanism 3 and moves to the maximum locking distance; when the paper is great, slide mechanism 3 drive sensor subassembly 4 reaches paper feed passageway 10 moves slide mechanism 3's the other end moves minimum locking distance, and passes through spacing portion 6 carries on spacingly, consequently, paper detection mechanism can control paper feed passageway 10 moves in order to adapt to not equidimension paper, make paper detection mechanism have the advantage that can adapt to the paper size.
