Description

Scanning device and image forming apparatus Technical Field The present utility model relates to the field of image forming technologies, and in particular, to a scanning device and an image forming apparatus. Background A multifunctional image forming apparatus having copy and scan functions has a scanning device by which a user can scan contents on a sheet. The scanning device compresses the paper on the light-transmitting manuscript table through the paper pressing plate component, so that the image reader can accurately acquire the content on the paper. In the prior art, as shown in fig. 1, some platen assemblies 14 include a platen metal 141 and a background plate Mylar sheet 142 (Mylar sheet), the background plate Mylar sheet 142 is glued to the platen metal 141, and the platen metal 141 is connected to the pressing member of the scanner 10. During operation of the scanner 10, the background plate Mylar sheet 142 contacts the paper, and the platen assembly 14 compresses the paper against the light transmissive platen under the action of the compression member. However, when the background plate Mylar sheet 142 is adhered to the platen 141, once the adhesion is poor, the background plate Mylar sheet 142 is prone to be skewed, wrinkled or air bubble, which further results in uneven contact surface between the background plate Mylar sheet 142 and the paper, and affects the scanning effect. In addition, the adhesive mode has short service life, and the adhesive effect gradually decreases after long-term use. And this kind of mode needs to assemble the cardboard alone, installs the cardboard again on the scanning device, involves the part more, and the equipment process is comparatively complicated, and the cost is higher. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a scanning device and image forming equipment, which are used for replacing the existing assembly paper pressing plate, so that the cost of the scanning device can be reduced. According to a first aspect of the present utility model there is provided a scanning device comprising; the first light-transmitting manuscript table is used for transmitting scanning light; And the conveying lower cover comprises a paper pressing area, wherein the paper pressing area is used for pressing the sheet passing through the paper pressing area to the first light-transmitting manuscript table so that the scanning light scans the sheet. According to the scanning device, the sheet passing through the paper pressing area is pressed to the first light-transmitting manuscript table by the paper pressing area on the lower cover, so that scanning light scans the sheet, the existing assembly paper pressing plate is replaced, and the cost of the scanning device can be reduced. In some embodiments, the conveying lower cover comprises a conveying lower cover body and a paper pressing plate, wherein the paper pressing plate and the conveying lower cover body are integrally formed, and the paper pressing area is the paper pressing plate. In some embodiments, the paper pressing plate includes a paper pressing plate body and a plurality of elastic members, and the elastic members are stressed to elastically deform so as to push the paper pressing plate body towards the first light-transmitting platen.
