Embodiment Construction

[0019] The CIS scanner provided by the present invention utilizes an elastic supporting component to keep a fixed distance between the contact image sensor module and the window glass when moving. The elastic supporting component may include a ring unit and a branch unit. Wherein, the annular unit is movably sleeved on the guide rod. The branch unit passes through the hole of the carrying device, abuts against and supports the contact image sensor module, and keeps a fixed distance from the window glass when moving.

[0020] The side view of the first embodiment of the present invention is as figure 2 As shown, it includes a window glass 300, a contact image sensor module 302, a carrying device 304, a guide rod 306, two smooth components 308, a guide component 310 and an elastic support component 312a. The window glass 300 is used to place documents or pictures 314 to be scanned. The contact image sensor module 302 is located under the window glass 300 and includes a conta...

Abstract

The invention provides a scanner that includes a connection type image sensor and an elastically supporting component. The elastically supporting component makes image sensor avoid the disadvantage of blur image captured by the image sensor caused by vertical shifting that is caused by mechanical friction or some factors that cannot be anticipated when connection type image sensor module is scanning.

Description

technical field [0001] The present invention relates to a scanner, in particular to a scanner comprising an elastic supporting component. Background technique [0002] A scanner with a contact image sensor (CIS) is a common computer peripheral device used to scan documents or pictures for conversion into digital data for storage or further processing by a computer. [0003] A CIS scanner module generally includes a light source, a focusing lens, an image sensor and a carrying device. However, the focus range of the CIS scanner module is only 0.3mm, that is, the document or picture can be clearly recorded ±0.3mm is the acceptable image range, beyond this range, the received image will be blurred and unrecognizable. Since the focus range of the CIS scanner module is too small, such as figure 1 As shown, when the carrying device 108 moves along the guide rod 200 , there may be unpredictable vertical displacement due to the uneven guide rod 200 or other mechanical factors, so ...
