Problems solved by technology

This structure is bulky, making it inconvenient to manufacture compact wearable smart devices, and the transmission and reception of optical signals must pass through two mirrors and swing components. After multiple reflections, the optical energy is lost, resulting in low utilization of laser signals. The recognition rate is reduced; and since each reflective surface is not absolutely flat, multiple reflections can also cause optical distortion

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] combine figure 1 and figure 2 As shown, the scanner of the present invention includes a light source transmitter 1, a swing assembly 2, a reflector 3 and a light source receiver 4, the scanner reduces the number of reflections, improves the recognition rate of the barcode 5, and is compact in structure and light in weight, and can Suitable for wearable smart devices.

[0024] The light source emitter 1 can be a laser diode for emitting point light. The light emitted by the light source transmitter 1 is visible light with a wavelength not less than 650nm. However, when the scanner is used for a long time, it is easy to generate heat, which directly affects the wavelength of the emitted light, causing the wavelength of light received by th...

Abstract

The invention provides a scanner which comprises a light source emitter, a reflector arranged corresponding to the light source emitter, a swing assembly driving the reflector to swing and a light source receiver, and light emitted by the light source emitter is reflected by the reflector to form a scanning light beam with time difference so as to scan a bar code. The light source receiver receives light beams reflected by the bar code to read the code, and the reflector and the light source receiver are both arranged on the swing assembly and synchronously swing along with the swing assembly. Compared with the prior art, the reflecting mirror and the light source receiver are both arranged on the swing assembly, so that the reflecting mirror and the light source receiver synchronously swing along with the swing assembly, the position of the reflecting mirror and the position of the light source receiver are relatively fixed all the time, the reflection frequency is reduced, the bar code recognition rate is increased, and the structure is compact.

Description

technical field [0001] The present invention relates to the technical field of scanners, in particular to a scanner and a wearable smart device with the scanner. Background technique [0002] With the development of science and technology, more and more barcode payment scanning and application scanning are involved in life. A scanner is a reading device used to read the information contained in a barcode. Using optical principles, the content of the barcode is decoded and then transmitted to a computer or other identification device through a data line or wirelessly. Barcode scanners are widely used in commercial POS cashier systems, express warehousing and logistics, books, clothing, medicine, banking, insurance and communications. [0003] In the technical solution with the application number of 201210278779.4 in the prior art, the light source transmitter and the light source receiver are separated in the horizontal direction and arranged at an angle to each other. In or...
