Description

Adjustable scanning device

The present invention relates to a scanning device, and more particularly to an adjustable scanning device with an adjustable scanning channel size.

A conventional scanning device includes a base, a first contact sensor (CIS), an upper cover, and a second contact sensor. The first contact sensor is mounted on the base, and the upper cover is pivotally connected to the base above the first contact sensor. The second contact sensor is fixedly mounted on the lower surface of the upper cover, and forms a fixed scanning path with the first contact sensor for the scanning object to pass and scan.

However, the thickness of the scanned objects is not the same, such as paper, bank cards, etc., their thickness difference is relatively large, if you set a small fixed scanning channel, for thicker cards, especially bank cards, etc. When entering the scanning channel, the card may enter into a misalignment or skew due to a large friction with the first contact sensor and the second contact sensor, and an effective scanning cannot be performed. However, if a large fixed scanning channel is set, when the thin paper enters the scanning channel scanning, the paper is out of focus due to the excessive distance between the paper and the second contact sensor.

Therefore, it is necessary to provide an adjustable scanning device that can adjust the size of the scanning channel as needed to meet different needs of users.

The purpose of the present invention is to provide an adjustable scanning device that can adjust the size of the scanning channel as needed to meet the different needs of the user.
