[Prior art]
2. Description of the Related Art Conventionally, some image forming apparatuses such as a copy form an image on both sides of a recording medium. This type of image forming apparatus includes, for example, a reversing re-feeding device (recording medium storage device) R as shown in FIG. 9 and is orthogonal to the recording medium conveyance direction f so as to be able to perform, for example, jam processing. It is detachable from the image forming apparatus main body in the direction.
[0003]
The reversing re-feeding device R feeds a recording medium on which an image has been formed on one surface by the image forming device from the direction of arrow g, inserts it into the switchback transport path 2 by the switchback roller 1 in the direction of arrow i, and temporarily stores therein. After that, the switchback roller 1 is reversely rotated to switch back in the direction of arrow j, reversed 180 degrees by the reversing roller 3 and transported through the transport path 5 by the plurality of transport roller pairs 4 and sent out in the direction of arrow k. Then, the sheet is returned to the sheet supply path 7 again by the relay roller 6 of the image forming apparatus main body, re-supplied to the image forming apparatus and an image is formed on the other surface, and then discharged.
[0004]
However, in order to form an image on both sides of a recording medium having a maximum length Pmax on which an image can be formed, as shown in FIG. The path length L needs to be longer than the maximum length Pmax of the recording medium on which an image can be formed. For this reason, there is a problem in that the transport path length L of the switchback transport path 2 becomes large, and the entire image forming apparatus becomes large.
[0005]
Therefore, in the conventional reversing re-feeding device R, for example, as shown in FIG. 11, a rib 8 is provided in the switchback conveyance path 2 in the front of the recording medium insertion direction, and the switchback conveyance path 2 is provided in the direction of the arrow i. In some cases, the leading end of the inserted recording medium is conveyed in the direction of arrow m and lifted upward, for example, to avoid contact with the relay roller 6 so that the length of the reversing sheet re-feeding device R is shortened.
[0006]
However, in such a conventional reversing and re-feeding device R, the height h of the reversing and re-feeding device R is increased by an amount corresponding to the provision of the rib 8, so that the reversing and re-feeding device R is pulled out from the image forming apparatus main body. Therefore, there is a problem that a necessary space around the main body of the image forming apparatus must be ensured to be large.
[0007]
For this reason, as shown in FIG. 12, the inventor rotates to the raised position shown by the solid line in the figure when attached to the image forming apparatus main body, and the non-raised position shown by the chain line in the figure when pulled out from the image forming apparatus main body. The reverse re-feeder R provided with the guide member 9 that rotates in the reverse direction is proposed. In such an inverting re-feeding device R, the height h of the inverting re-feeding device R can be reduced when it is pulled out from the image forming apparatus main body. Installation space can be reduced.

Send out.
[0041]
FIG. 2 shows the front of the reversing and re-feeding device 22 in the sheet insertion direction (recording medium insertion direction) I. A guide member 50 is provided in front of the sheet reversing device 22 in the sheet insertion direction I. As shown in the drawing, the guide member 50 has a shaft-shaped base 52 having shafts 51 at both ends rotatably supported by the frames on both sides of the reversing and re-feeding device 22, and extends downward from a rear end of the shaft base 52. For example, three lever portions 54 for attaching a leaf spring-like elastic member 53 bent in the form of three are provided at the base portion 52 at an interval in the axial direction as shown in the figure, and each is extended forward from the base portion 52 in the paper insertion direction I. And a guide portion 55.
[0042]
A notch is provided at the tip of each guide portion 55. The base end of the second guide portion 58 is inserted into the cut to support the shaft, and the second guide portion 58 is rotatably attached to each guide portion 55. Although not shown, a biasing member is provided at the mounting portion, and biases the second guide member 58 counterclockwise.
[0043]
Then, as shown in FIG. 2, when the reversing re-feeding device 22 is detached from the copying machine main body 10, the guide member 50 holds the guide portion 55 in a horizontal state by gravity. The guide member 58 is also placed in a horizontal state by contacting the lower portion of the base end with another member (for example, a bottom plate provided in the reversing re-feeding device) so that the guide portion 55 and the second guide member 58 are aligned with each other as shown in FIG. I do.
[0044]
However, when the reversing and re-feeding device 22 is attached to the copying machine main body 10, the positioning member 60 provided in the copying machine main body 10 enters through the long hole 57 formed in the frame of the reversing and re-feeding device 22 and engages. In this case, as shown in FIG. 4, the reversing re-feeding device 22 is positioned in the copying machine main body 10. At the same time, the positioning member 60 engages with the elastic member 53 and pushes through the elastic member 53 to rotate the guide member 50 about the support shaft 51 in the direction of arrow P, and as shown in FIG. It is held in a rotating state at an angle θ in contact with a stopper member 62 provided in the main body 10.
[0045]
At this time, the second guide member 58 is rotated in the direction of arrow Q by the urging force of the urging member together with the rotation of the guide member 50. Then, the guide member 50 is set to the ascending position, and the second guide member 58 is turned to the ascending position by rotating the second guide member 58 by an angle φ with respect to the guide member 50 with the base end lower portion O pressed against another member. The tip of the second guide member 58 is raised to the height H, and the two guide members 58 are apparently inclined at an angle α.
[0046]
Thus, when the sheet on which the single-sided image is formed is inserted into the reversing and re-feeding device 22, the leading end in the insertion direction I is guided upward by the guide member 50, and then further guided upward by the second guide member 58. Then, the sheet is stored in the reversing and re-feeding device 22 with the height in the front of the sheet insertion direction I raised by the height H. Therefore, since the sheet is stored with the leading end thereof lifted, the length of the sheet reversing device 22 in the sheet insertion direction I can be shortened.
[0047]
Conversely, when pulling out the reversing and re-feeding device 22 from the copying machine main body 10 for jam processing or the like, as shown in FIG. 2, the engagement with the positioning member 60 is released and the guide member 50 is reversed based on gravity. Rotate. In addition, since the second guide member 58 abuts on the other portion of the second guide member 58 at the base lower portion O with the reverse rotation of the guide member 50, the second guide member 58 reversely rotates against the urging force of the urging member. Then, the guide member 50 is returned to the non-elevated position, and the second guide member 58 is rotated reversely with respect to the guide member 50 to return to the non-elevated position, as shown in FIG.
[0048]
As a result, the size of the reversing and re-feeding device 22 to be pulled out can be reduced, the space used around the image forming device when drawing out the reversing re-feeding device 22 can be narrowed, and the space required for installing the image forming device can be reduced.
[0049]
If the height of the front of the sheet is raised at an angle θ using a conventional reversing sheet re-feeding device R using one guide member 9 as shown in FIG. 12, as shown in FIG. The length of the guide member 9 must be N longer than the length M where the guide member 50 and the second guide member 58 shown in FIGS. 2 to 4 are connected, so that the copier main body 10 can be reduced in size. Can not. If the length of the guide member 9 is reduced to increase the height H, the angle θ must be increased. If the angle θ is increased, it takes time to return the guide member 9 to the non-elevated position.
[0050]
Incidentally, a small roller 64 may be rotatably provided as a third guide member in front of the second guide member 58 in the sheet insertion direction I, for example, as shown in FIG. 7 is a biasing member for biasing the second guide member 58, which is not shown in the above-described example, and is wrapped around a support shaft 66 of the second guide member 58, and one end is guided by the guide portion 55. And the other end is hooked on the second guide member 58. Reference numeral 67 denotes a shaft hole into which the support shaft 66 is inserted at the end of the guide portion 55.
[0051]
In this way, as shown in FIG. 8, when the paper 70 is further guided upward by the second guide member 58, the small roller 64 contacts and rotates the small roller 64, and the paper 70 and the second guide member 58 The frictional resistance is greatly reduced, and the paper 70 can be smoothly guided upward.
[0052]
In the above-described example, the case where the recording medium storage device is the reversing re-feeding device 22 has been described. However, the recording medium storage device is not limited to the reversing re-feeding device 22 and can be attached to the image forming apparatus main body so as to be freely drawn. For example, a paper feeding device or a paper discharging stack device may be used as long as a recording medium such as paper or an OHP film is inserted and stored.
