Optionally, the camera rotates around a pivot, and the distance between the pivot and each place of the scanning window is equal.

Optionally, a motor is connected to the pivot for driving the pivot to rotate.

Optionally, a display screen is disposed on the front surface of the housing, an opening extends from the front end surface of the housing to the back surface, and a circular arc transparent lens is embedded in the opening to form the scanning window.

Optionally, a light supplementing lamp is included, and the light supplementing lamp and the camera are integrated and rotate simultaneously.

Optionally, an aiming light source to project an aiming pattern, the aiming light source being integrated with the camera.

Optionally, when the camera rotates to different positions, the distance between the scanning window and the camera remains unchanged.

Optionally, the rotation angle of the camera is 0-90 degrees.

Optionally, an angle sensor is included to control the rotation angle of the camera.

Compared with the prior art, the utility model has the following beneficial effects:

according to the bar code scanner, the circular arc-shaped scanning window is arranged, so that when the camera rotates to different angles, bar codes can be acquired through the scanning window, and the rotation angle of the camera can be increased; and because the volume of the parts which need to be rotated is small, the volume of the whole bar code scanner is reduced and the reliability of the bar code scanner is improved on the premise of increasing the rotation angle of the camera.

Detailed Description

For a better understanding of the utility model with objects, structures, features, and effects, the utility model will be described further with reference to the drawings and to the detailed description.

The barcode scanner 100 disclosed by the utility model can be a device which can perform barcode scanning, such as PDA (Personal Digital Assistance), a mobile phone, a tablet personal computer, an interphone, a scanning gun and the like.

In one embodiment shown in fig. 1 and 2, the barcode scanner 100 is a PDA, the barcode scanner 100 includes a housing 1 for holding, and a display screen 2 is disposed on the front surface of the housing 1, so as to display barcode information collected by the barcode scanner 100. The front end face of the shell 1 is provided with an opening 3, the opening 3 extends from the front end face of the shell 1 to the back face, and a circular arc-shaped transparent lens 4 is embedded in the opening 3, so that a circular arc-shaped scanning window 5 is formed.

A scan engine 6 is accommodated in the housing 1 and exposed to the scan window 5, so as to collect bar codes through the scan window 5. The scanning engine 6 is integrated with a camera 7, a light supplementing lamp 8 and a sighting light source 9, the camera 7 is used for collecting bar code images, the light supplementing lamp 8 is used for providing light for lighting bar codes, the sighting light source 9 is used for projecting sighting patterns to aim at the bar codes, the scanning engine 6 is accommodated in a support 10 made of metal, one end of the support 10 is connected with a motor 12 through a pivot 11, the other end of the support 10 is connected with an angle sensor 13, the motor 12 drives the pivot 11 to rotate so as to drive the scanning engine 6 to rotate, and the angle sensor 13 monitors and controls the rotation angle of the scanning engine 6; the pivot 11 is set to have equal distances from the transparent lens 4 of the scanning window 5, that is, the pivot 11 can be used as the axis of the circular arc-shaped transparent lens 4, so that the distance between the camera 7 and the transparent lens 4 is kept unchanged no matter what angle the scanning engine 6 rotates, the image distortion generated by the transparent lens 4 is adjusted by an algorithm, and the adjustment cost is reduced.

As can be seen from the figure, the transparent lens 4 is approximately in a circular arc shape with 90 degrees, so that the scanning engine 6 can rotate from a direction facing the front to a direction facing the back, that is, the rotation angle of the scanning engine 6 is 0-90 degrees, the rotation angle of the scanning engine 6 is greatly improved, and the requirements of different rotation angles of different users are met. The rotation angle of the scan engine 6 may be continuously variable between 0-90 ° as desired, such as any angle between 0-90 ° with a user-input rotation angle of 31 °, 62.5 °, etc.; alternatively, the rotation angle of the scan engine 6 may be stepwise varying between 0-90 °, i.e. the scan engine 6 may be rotated only by a specific few degrees, such as 20 °, 45 °, 60 °, 75 °, etc.

In other embodiments, the camera 7 and the light-compensating lamp 8 may not be integrated, but may be provided separately; or only the camera 7 is rotatable, but other elements (such as the light-compensating lamps 8) are not rotatable, so that a plurality of light-compensating lamps 8 with different light-emitting angles can be arranged, when the camera 7 rotates to a certain angle, the corresponding light-compensating lamps 8 are turned on, and of course, all the light-compensating lamps 8 can be turned on under the premise of neglecting power consumption.

The bar code scanner of the utility model has the following beneficial effects:

according to the bar code scanner 100, the circular arc-shaped scanning window 5 is arranged, so that when the camera 7 rotates to different angles, bar codes can be acquired through the scanning window 5, and the rotation angle of the camera 7 can be increased; and because the volume of the parts which need to be rotated is small, the volume of the whole bar code scanner 100 is reduced on the premise of increasing the rotation angle of the camera 7, and the reliability of the bar code scanner 100 is provided.

The above detailed description is merely illustrative of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the utility model.
