Description

Scanning device

Technical Field

The present disclosure relates to a scanning device, and more particularly, to a scanning device capable of increasing the scanning width and being used for objects to be measured with different scanning ranges

Background

Generally, a scanning device in the market, such as a conventional machine, scans an object with a fixed and narrow width. However, if it is necessary to scan a piece of cloth or other wide objects for detection, it is necessary to improve the scanning device or add another scanning device.

However, in the conventional improvement method, it is often necessary to select a specific specification of components or to combine a plurality of components according to the width of the object to be scanned, so as to improve the scanning device.

These approaches require expensive parts or require pieces to be put together. However, any piece together without any overall layout is prone to cause gaps or height differences between the components or structures, so that if the object to be tested needs to touch the scanning device for scanning, resistance is generated between the scanning device and the object to be tested, and thus, a roller or other means is needed to overcome these problems.

Furthermore, the combination of parts may cause poor compatibility or interference problems without general consideration, for example, if there are more than two image sensors in the scanning device, the depth of field between the two image sensors may be inconsistent. Therefore, a scanning device is needed to solve the above-mentioned problems.
