Abstract: A thickness detecting mechanism is provided for detecting a thickness of a to-be-measured article. The thickness detecting mechanism includes a detecting arm and an optical displacement sensing module. The detecting arm is moved as the to-be-measured article is sustained against the detecting arm. The detecting arm includes a surface. The optical displacement sensing module detects the surface of the detecting arm when the detecting arm is respectively located in a first position and a second position. According to the displacement amount of the detecting arm from the first position to the second position, the thickness of the to-be-measured article is acquired.

Abstract: A sheet laminating apparatus with an instant heat control function includes a first cylindrical roller, a second cylindrical roller, a first long metal sheet, a first heat-generating case, a second long metal sheet, a second heat-generating case, a contact sensor and a controller. The first long metal sheet and the second long metal sheet are very thin and small, so that the temperature is quickly changed. By using the contact sensor to detect the surface temperature of the first cylindrical roller under control of the controller, the instant heat control function of the sheet laminating apparatus is achieved.

Abstract: A spacing interval control method is used in a sheet laminating apparatus for controlling a constant spacing interval between any two adjacent ones of multiple documents. The sheet laminating apparatus includes an automatic document feeding mechanism and a sheet laminating mechanism. By means of multiple sensors within the automatic document feeding mechanism, multiple documents are successively transported from the automatic document feeding mechanism to the sheet laminating mechanism at a constant spacing interval between any two adjacent ones of multiple documents. As a consequence, the documents after being heated or pressed by the sheet laminating mechanism will be cut into multiple separate and identical-sized laminated documents.

Abstract: A paper shredder includes a shredder body, a bin, a sensing module and a dust cleaner. The dust cleaner has a cleaning element for cleaning the sensing module. The cleaning element is attached on a swing rod. The swing rod has a first end adjacent to the sensing module and a second end inserted into the bin. During the bin is withdrawn from the paper shredder, the swing rod is swung by the inner wall of the bin and thus the cleaning element is contacted with the sensing module to clear off the dust on the sensing module.

Abstract: A floating sheet article thickness detecting device for use in a sheet article processing mechanism includes two guiding slots, two glidable guide blocks, an elastic sustaining member and at least one thickness sensing module. The two glidable guide blocks are respectively embedded into the two guiding slots to render synchronous shift actions in the guiding slots. The elastic sustaining member includes a stationary sustaining element and a movable sustaining element. The stationary sustaining element and the movable sustaining element are separated when the sheet article passes therebetween, so that the movable sustaining element is subject to a thickness shift to form an elastic gap therebetween. The sheet article is fed into a sheet article feeding channel through the elastic gap. The thickness sensing module is synchronously moved with the thickness shift of the movable sustaining element according to the thickness of the sheet article, thereby generating a thickness detecting signal.
