Problems solved by technology

[0003] However, in a conventional scanner, when the sensing device 14 moves, the flexible circuit board 18 will stretch or bend accordingly. When the flexible circuit board 18 is bent, it will easily rub against the transparent cover 13, thus Scratches on the transparent cover 13 seriously affect the quality of scanning, or the bent flexible circuit board 18 often interferes with the sensing device 14, causing the scanner to fail

Abstract

This invention relates to one scanner, which comprises one shell, one host board, one sensor device, one roller structure and flexible transmission parts, wherein, the host board in set into shell and the sensor is into shell moving between first and second positions; roller structure has one axis part connected to the sensor device; the flexible transmission part has one first end and second end with first end connected to above sensor device and with second end connected to the above host board.

Description

technical field [0001] The invention relates to a scanner, in particular to a wire winding mechanism in the scanner. Background technique [0002] 1 shows a schematic diagram of a traditional contact image scanner (Contact Image Sensor scanner), which has an upper casing 11, a lower casing 12, a transparent cover 13, a sensing device 14, a guide rod 15, and a driving device 16. And flexible circuit board 18. The upper casing 11 has an opening 111 , and the transparent cover 13 is disposed on the opening 111 , and the object to be scanned (not shown in the figure, such as paper, photo, etc.) is placed on the transparent cover 13 . The sensing device 14 is arranged between the upper casing 11 and the lower casing 12, and a contact image sensor (not shown in the figure) is arranged inside. Scan objects to scan. The guiding rod 15 is disposed inside the lower casing 12 , and the sensing device 14 is connected to the guiding rod 15 by using the spanning portion 141 . The driv...
