いる。In a copying machine, a paper device in which two rollers are arranged side by side at a fixed interval, a belt is wrapped around the rollers, one of the rollers is driven to run a papermaking belt, and the paper is conveyed by the running of the belt. Nine things are known to be used. This device is designed to be attached to the main body of the copying machine with the belt and rollers formed into a papermaking unit by a frame, and copying can be done by operating a handle attached to the room so that it can be rotated by a predetermined angle. By pulling it out of the machine, you can remove jammed paper.

なることもあった。In such a paper conveyance device, paper jams can be easily removed, but if the paper becomes very wrinkled, it may come into contact with surrounding components and damage itself or tear itself when pulled out. . Particularly, as shown in FIG. 1, when paper 2 on which a toner image has been transferred from photosensitive drum 1 of a copying machine is transported, the paper may become accordion-shaped (indicated by l) due to a peeling error of peeling finger 3. If the paper conveyance device is pulled out toward the front in the figure by operating the handle in this state, the paper may damage the surface of the photoreceptor. In addition, there were cases where the paper was torn and remained in the back of the copying machine, making it difficult to remove.
従って、本発明の目的は、用紙の皺苦茶の程度が大きく

ないようにしている。In order to achieve such an object, according to the present invention, at least one roller is juxtaposed at a constant interval, a belt is wrapped around the rollers, and one roller is driven to cause the belt to run. The paper machine, belt, and rollers are integrated into the frame and attached to the machine body, and can be pulled out from the machine body by operating a rotatable handle on the frame. In the continuous paper transport device, the rollers are supported by a first frame such that the belt can pivot relative to the frame about one of the rollers while maintaining a predetermined spacing. A cam is fixed to the rotating shaft of the handle, and a cam abutting member is fixed to the first frame at a position facing the cam, respectively, to stop the belt from pivoting, and the rotation of the cam by operating the handle is fixed. provides a paper conveyance device characterized by a belt that pivots along with the belt, and by expanding the space in which the paper is conveyed by pivoting the belt, it is possible to prevent jams when the device is pulled out. This prevents the paper from coming into contact with surrounding parts.

も一つのローラとがあればよい。The paper conveying device 10 has a pair of rows 211, 12, and 13 arranged side by side at a constant interval, and a belt 14 that is passed around these rollers.
is driven by a motor or the like, and causes the belt 14 to run. As shown in FIG. 1, the belt 14 is formed as a large number of narrow bands in the axial direction of the roller, and has a series of holes 15 on the upper paper conveyance surface so as to apply negative pressure.
A vacuum chamber 16 is provided on the bottom surface of the belt in the paper conveyance path.
(Fig. 83) is formed, and the paper is sucked onto the belt surface through the belt hole 1S. For this reason, Laura
One row (11) has a large diameter and the other rows 912.13 have a small diameter, so that a vacuum chamber 16 is provided in the belt 14. However, the present invention is not limited to such a device, and basically includes one
It is sufficient to have one belt and at least one roller supporting the belt so that it can run.

かで自る。The paper conveying device 10 is detachably attached to a copying machine (not shown) as a whole by a lower frame 1F (FIG. 1). A handle 19 is attached to one side surface 1s of the frame 1T so as to be rotatable by a predetermined angle via a shaft 20, and is biased by a coil spring or the like, and as shown in FIG. You can do it by rotating it in the direction of ^.

In other words, the unit 24 is configured as a unit 24, and the unit 24 is attached to the frame IT by the rollers 11 so that the belt 14 pivots vertically with respect to the frame 1T about the rollers 11 while maintaining a predetermined interval. is supported by. Therefore, the unit 24 can pivot as indicated by the arrow in FIG.

The unit 24 is held in the traveling operating position. Although this cam contact member 26 is illustrated as a round bar extending and supported on both sides of the second frame 23, it may also be in the shape of a bottle protruding from each side. Instead, it may be provided only on the side surface 25 on the handle side. In this case, the rotation axis 20 of the handle 1s is the frame 1T.
It is not necessary that the cams extend to both sides 111, 21 of the cam 22, and it is sufficient to attach the 22 cams to the side 18. In short, any structure may be used as long as the cam 22 and the contact member 26 can stop the unit 24 from pivoting downward.

(solid line position in the figure) Next, when the handle 19 is rotated in the direction of the arrow ^ in FIG. 2, the cam 22 rotates via the rotating shaft 20 as shown by the broken line in FIG. Due to this rotation, the recessed portion 2T of the papermaking cam 22 is separated from the contact member 26, and the unit 2
4 has nothing to support its own weight, so roller 11
The abutting member 26 touches the other cam surface 2 of the cam 22 with
8 (dashed line in Figure 3). Therefore, the belt 14 and rollers 12 and 13 all descend,
The space between the photoreceptor drum 1 and the photoreceptor drum 1 is expanded. This descending length can be arbitrarily set depending on the shape of the cam l1lf28 of the cam 22.

When engaged, the entire conveying device is locked. This lock is designed to be unlocked by operating or rotating the handle 19. That is, when the handle 19 is operated, the unit 24 is lowered and the lock is released simultaneously, and the handle 18 is moved to the second position in the tt state.
When pulled toward the front in the figure, the entire device 10 is pulled out along the rails (not shown) of the copying machine.

機械に用いることもで舞ることは明らかである。According to the present invention, it is possible to widen the space for a paper jam that occurs in a narrow space, so that the jammed paper does not come into contact with surrounding members, such as the surface of the photoreceptor drum when the paper transport device is pulled out. Therefore, it is important to eliminate scratches caused by rubbing. In the embodiment, the paper conveying device is described as a paper conveying device used in a copying machine, but it is obvious that the present invention is not limited to this and can be used in other machines as well.
