[0007] However, in the above-mentioned conventional sheet conveying device, there is a concern that static electricity generated by conveying the sheet moves from the sheet to the first guide surface and accumulates on the first guide surface and inside the device.
In this case, in this sheet conveying device, there is a possibility that the processing quality of the processing section may be lowered due to electrostatic dust and the like being attracted, or that the sheets conveyed to the sheet stacking section may differ from those previously conveyed to the sheet stacking section. The sheets are attached to each other due to static electricity, resulting in poor stacking of the sheets

Embodiment 1
[0076] Such as Figure 1 ~ Figure 4 As shown, the image reading device 1 has a main body portion 8 and an opening and closing portion 9 . The main body part 8 is a flat substantially box-shaped body, and a figure 1 The operation panel 5 is shown. Such as figure 2 As shown, the image forming unit 4 is provided on the lower side of the main body portion 8 . Although not shown, the image forming unit 4 accommodates an image forming unit such as an inkjet type or a laser type. Such as figure 2 as well as Figure 4 As shown, a reading unit 30 is provided on the upper side of the main body portion 8 . A platen glass 7 is disposed on the upper surface of the reading unit 30 , and the upper surface of the platen glass 7 serves as a placement surface 8A. When reading a document such as a sheet or a book in a stationary state, the document is placed on the placement surface 8A.

Embodiment 2
[0140] In the image reading device 1 of Embodiment 1, the discharge section member 60 is not connected to the ground, but for example Figure 10 In the image reading apparatus according to the second embodiment shown, the discharge part 60 may also be connected to the ground line E1. The other structures of the second embodiment are the same as those of the first embodiment, so illustration and description are omitted.
[0141] In the image reading device of Embodiment 2, the conductive member 60 has the ground portion 67 on the front end side of the engaging portion 66A. The ground portion 67 is continuous with the contact portion 63 .
[0142] A fixing screw 102 and a compression coil spring 101 are arranged in a space around the engaged portion 76A of the guide member 70 . The fixing screw 102 is located on the lower side of the ground portion 67 and fixes a section of the ground wire E1 to the guide member 70 . The other end of the ground wire E1 is disposed inside the ...
Embodiment 3
[0145] In the image reading device 1 of Embodiment 1, the first guide surface 70G and the contact portion 63 of the conductive member 60 contact the sheet 99 conveyed to the sheet stacking portion 6 from the lower side, but is not limited to this structure. For example, if Figure 11 In the image reading apparatus of Embodiment 3 shown, the first guide surface and the contact portion of the conductive member may also come into contact with the sheet conveyed to the sheet stacking portion from the upper side.
[0146] The image reading apparatus of Embodiment 3 has: the supply portion 305 , sheet stacking portion 6 , automatic document conveyance mechanism 10 , and conveyance path P1 in which the upper and lower relationships in Embodiment 1 are substantially reversed. Part 306, automatic document feeding mechanism 310, and feeding path P31. That is, the supply portion 305 is located on the upper side of the sheet stacking portion 306 . After advancing to the left from the su...

Abstract
The present invention provides a sheet conveyor device that restricts or reduces degradation of processing quality in a processing portion and occurrence of a sheet stacking failure on a sheet stack portion due to buildup of static electricity. The sheet conveyor device includes a processing portion; a sheet stack portion where sheets on which processing has been performed by the processing portion are stacked; and a conveyor that is configured to convey a sheet to the processing portion and further conveys the sheet along the conveyance path to the sheet stack portion. The conveyor includes an ejection roller that ejects the sheet being conveyed along the conveyance path, to the sheet stack portion. The sheet conveyor device includes a first guide surface that is disposed downstream of the ejection roller in the conveyance path and directs the sheet toward the sheet stack portion while contacting the sheet being conveyed; a contact portion that is exposed at the midway of the first guide surface and comes into contact with the sheet being conveyed; and a conducting member having a discharge portion that discharges static electricity transferred to the contact portion by contact between the sheet and the contact portion.
Description
technical field [0001] The present invention relates to a sheet conveying device. Background technique [0002] Patent Document 1 discloses an example of a conventional sheet conveying device. The sheet conveying device has: a processing section that performs processing on the sheet; a sheet stacking section that stacks the sheets processed by the processing section; and a conveying unit that transfers the sheet It is guided to the processing section, and further transported along the transport path that guides the sheet to the sheet stacking section. The transport unit has discharge rollers. The discharge rollers convey the sheets conveyed along the conveyance path toward the sheet stacking portion. In addition, the sheet conveying device has a first guide surface. The first guide surface is provided on the downstream side of the discharge roller in the conveyance path. The first guide surface guides the conveyed sheet toward the sheet stacking portion while contacting...
