Embodiment Construction

[0020] When scanning, the text on the paper should be parallel or approximately parallel to the image sensor to obtain a clear image, and the scanning pen must be perpendicular or approximately perpendicular to the paper to conform to people's usage habits. The two are contradictory. The existing technology To solve this contradiction by customizing lens groups and reflectors, the present invention proposes a solution with better effect and lower cost.

[0021] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] figure 2 It is a schematic diagram of the overall appearance of an embodiment of the scanning pen of the present invention. Such as figure 2 As shown, in the technical solution of this embodiment, the scanning pen includes from the outside: a housing 1 , a trigger pin 2 , a function key 3 and a collection window 4 .

[0023] The trigger pin 2 is located at ...

Abstract

The invention discloses a scanning pen, and belongs to the field of peripheral input equipment of computers. The scanning pen comprises a shell, a main circuit board positioned at the upper end of the shell, and an image sensor board positioned at the lower end of the shell, wherein the image sensor board is equipped with an image sensor and a lens. The scanning pen also comprises an inter-board connecting seat used for connecting the main circuit board and the image sensor board, so that when the scanning pen scans, the image sensor is parallel or approximately parallel to a canned medium. In the scanning pen, the circuit board is connected through the inter-board connecting seat, so that a universal lens instead of the customized special lens system is adopted, a reflector used for changing an optical path in the prior art is saved, the influence of the reflector on the optical path is eliminated, the flexibility of the structure is improved and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of computer peripheral input devices, in particular to a scanning pen used for text entry. Background technique [0002] In people's work and life, it is often necessary to enter scattered text. At present, the scanning pen is an effective tool for realizing loose text entry. The existing technology of the scanning pen is realized by using a reflective optical path. [0003] US Patent US6509893B1 has introduced the structure of the existing scanning pen in detail. figure 1 It is a schematic structural diagram of a scanning pen in the prior art. Such as figure 1 As shown, the main circuit board 106 is assembled at the middle rear of the casing 101 . The front end of the main circuit board 106 is soldered with an image sensor 103 . A customized lens system 116 is assembled on top of the image sensor 103 . The lens group 115 is fixed at the front end of the lens system 116 , and the mirror 117 is fixed at the rear...
