Abstract:
1. A transmission mechanism for scanning device, comprising: a scanning unit, having a connecting portion and a supporting portion; a rail, wherein the scanning unit is slidely disposed on the rail through the supporting portion; and a transmission element, connected to the connecting portion of the scanning unit to drive the scanning unit sliding along the rail, wherein the rail is located on a plane, the scanning unit slides on the plane, and an orthogonal projection of the connecting portion on the plane and an orthogonal projection of the supporting portion on the plane are overlapped with each other, wherein the scanning unit has two side surfaces opposite to each other, the two side surfaces are both orthogonal to moving directions of the scanning unit, and the transmission element is a synchronous belt, and an end of the synchronous belt is connected to one of the two side surfaces of the scanning unit, while another end of the synchronous belt goes around the rail and is connected to the other one of the two side surfaces of the scanning unit.
