Problems solved by technology

In addition, whether it is a single-pass scanner or a multi-pass scanner has its specific driving power conditions, but if the scanner's placement environment cannot provide specific driving power conditions, the scanner will not work
It can be seen from this that the known double-sided document scanner needs to be limited to a specific type of power supply to operate, so it lacks flexibility in use and will cause inconvenience to users.

Embodiment Construction

[0029] Please refer to Figure 1A to Figure 4 . The paper-fed double-sided document scanner 1 includes a first image sensing component 10 , a second image sensing component 11 , a paper feeding mechanism 12 , a power receiving interface 13 , a channel 14 , and a control circuit 16 . The control circuit 16 is coupled to the first image sensing component 10 , the second image sensing component 11 , the paper feeding mechanism 12 and the power receiving interface 13 (shown by dashed lines in the figure).

[0030] In a specific embodiment, the channel 14 may include a paper feeding path in a horizontal direction or a paper feeding path extending in multiple different directions, but not limited thereto. The first image sensing element 10 and the second image sensing element 11 can be respectively disposed on opposite sides of the channel 14 and arranged alternately. The paper feeding mechanism 12 is used to feed documents 2 through the channel 14 . The paper feeding mechanism 1...

Abstract

The invention discloses a paper feeding double-sided file scanner capable of changing a scanning mode according to power input. The scanner comprises a first image sensing component, a second image sensing component, a paper feeding mechanism, an electric power receiving interface and a control circuit, wherein the paper feeding mechanism is used for feeding a file through the first image sensing component and the second image sensing component; the electric power receiving interface is used for receiving power; when received electric power is lower than a preset threshold value, the control circuit controls the scanner to scan the first side and the second side of the file in a first mode; and when the received electric power reaches the preset threshold value, the control circuit controls the scanner to scan the first side and the second side of the file in a second mode.

Description

technical field [0001] The present invention relates to a paper-fed double-sided document scanner, in particular to a scanner capable of scanning double-sided documents in different scanning modes according to different power supply. Background technique [0002] Known double-sided document scanners are divided into multi-pass scanners with one image sensing component, such as a CCD Image Sensor with a charge-coupled device, and multi-pass scanners with two image sensing components. Single pass (one-pass) scanner. [0003] For the scanning mode of the single-pass scanner, the document only needs to pass through two sets of image sensing components that are relatively staggered once, and the scanner can scan the images on both sides of the document; however, the multi-pass scanner only has one set of images. Like the sensing assembly, multi-pass scanners must therefore have a paper return path that provides a paper return path for the document to return and pass through the ...
