Problems solved by technology

The frame 13 that fixes the glass plate 12 is generally made of plastic and has a protrusion 13a. When the scanning module 3 moves under the glass plate 12, the plastic deformation of the frame 13 may cause the scanning module 3 to collide when moving. to the protruding portion 13a, causing the scanning module 3 to fail to move smoothly to the bottom of the document platform 11 for scanning operations
However, if the protrusion 13a is removed and the glass plate 12 is directly bonded to the vertical wall 13b of the frame 13, although the problem of moving the scanning module 3 can be solved, the glass plate 12 will lose the support of the protrusion 13a, and debonding will occur after long-term use. problem, so as to shorten the service life of the auto-feed scanning unit

Abstract

The invention provides an automatic paper feeding scanning device. The automatic paper feeding scanning device includes an automatic paper feeding device and a flatbed scanner. The platform scanner includes a housing, a scanning module and a scanning platform, and the scanning platform has a first scanning window and a second scanning window, which are used to fix the first light-transmitting plate and the second light-transmitting plate respectively, wherein the second scanning window The inner edge is complementary to the side edge of the second transparent plate. The present invention has the advantages of preventing the scanning module from being impacted while moving and preventing dust from falling into the housing.

Description

technical field [0001] The invention relates to a scanning device, in particular to an automatic paper-feeding scanning device. Background technique [0002] Various machines equipped with an automatic paper feeding device to provide an automatic paper feeding function, such as printers, scanners, fax machines, etc., have become common peripheral devices for computers. Such as figure 1 as shown, figure 1 It is a front sectional view of an existing automatic paper feeding scanning device. The existing automatic paper feeding scanning device 1 includes an automatic paper feeding device 1 a and a scanning device 1 b, wherein the automatic paper feeding device 1 a is installed on the upper cover 2 . The automatic paper feeder 1a has a paper feed outlet 14 for feeding paper out of the automatic paper feeder 1a. [0003] The scanning device 1b includes a scanning housing 10, a light-transmitting platform 11, a glass plate 12, a frame 13 and a scanning module 3, wherein the scan...
