Abstract

The invention relates to a drive device of scanner, which comprises a support mounted inside the base to support the image sensor. Said drive device comprises a guide unit mounted inside the base along the first direction; several transverse rolling wheels mounted on the bottom of support and rolling on the top surface of guide unit; several longitudinal rolling wheels rolling on the surface of guide unit; a pushing unit for forcing a second direction pushing force on the supported surface of guide unit; and a power unit for driving the support move along the first direction. The invention can improve the motion stability and scanning quality.

Description

technical field [0001] The invention relates to a driving device of an image scanner, in particular to a driving device of the scanner which can make the scanning component move smoothly and thus improve the scanning quality. Background technique [0002] Such as figure 1 , 2, and 3, the general scanner 10 has a base 11, a metal guide rod 12 installed in the base 11 along a first direction X, and a second direction perpendicular to the first direction X Y is placed and sleeved on the metal guide rod 12 and carries a support frame 14 of a contact image sensor 13, a power installed in the base 11 and capable of driving the support frame 14 to move along the first direction X unit 15, and a cover glass cover 16 placed on the top side of the base 11. [0003] When scanning, the support frame 14 is sleeved on the metal guide rod 12 and slides, and often swings along the first direction X, resulting in poor scanning quality, and has the disadvantage of relatively large friction ...
