In practice, the scanning area 115 of the first platform 11 is configured to transmit the scanning light of the scanning module 20 to the object 80 to be scanned to generate the image signal 25 in cooperation with the scanning module 20.

The positioning adjustment module 30 is disposed on the second platform 12, and the positioning adjustment module 30 includes a length adjustment mechanism 31 and a first sensor 32. The positioning adjustment module 30 is adjacent to the first platform 11 and the second platform 12 The line is set. In practice, the first sensor 32 can be designed as a slotted modular component, and the user can fit the first sensor 32 into the length adjusting mechanism 31 and adapt to the actual use. In contrast, the first sensor 32 is used to detect the boundary position 81 of the object 80 and issue a boundary signal 82.

The processing module 40 is electrically connected to the scanning module 20 and the first sensor 32 for receiving the image signal 25 and the boundary signal 82. The processing module 40 receives the image signal 25 and can store the image signal 25 in the device. Built-in dynamic memory or a variety of storage modules such as external hard drives or flash drives. When the first sensor 32 presses the trigger, the processing module 40 activates the scanning module 20 to scan and controls the scanning module 20 to move to the boundary position 81 according to the boundary signal 82 to avoid overtravel scanning. Therefore, the boundary signal 82 is generated before the scanning module 20 is actuated to the boundary position 81.
