Abstract

PROBLEM TO BE SOLVED: To facilitate insertion of curled manual insert paper by fitting a lower guide member which supports manual insert paper from the bottom side, and an upper guide member which faces the lower guide member at a constant interval and retreats backwards as a front end advances to both-end side. SOLUTION: This guide is of such an arc shape as the front end 54 of an upper guide member 52 has a central part 53 protruding forward to the maximum paper width and the front end of the paper whose length is minimum protrudes by a length long enough for the front end of the paper of minimum length to reach a conveyance roller 44. Manual insert paper 56 is placed on a lower guide member 50, using size marking, and the central part 57 of the front end of the manual insert paper 56 is positioned between the upper guide member 52 and the lower guide member 50 to move the paper 56 forward. The curled part 58 of the manual insert paper 56 comes into contact with the front end 54 of the upper guide member 52 to correct the curled part 58 as the paper 56 is inserted, enters the underside of the upper guide member 52, and advances to the conveyance passage through the conveyance roller.

Next, a first embodiment of the present invention will be described. 2 and 1, the lower guide member 50 of the manual paper insertion guide 48 is provided in a horizontal state. The left and right widths of the lower guide member 50 are large so that wide sheets such as A0 and A1 can be inserted. The front and rear length of the lower guide member 50 (as viewed from the user) is such that the user can place a manual feed sheet and place a hand on the sheet to hold down the sheet, or a sheet between the upper guide member to be described later. Is of a predetermined size so that the central part of can be positioned. A0, A1, A2, A2 are symmetrically arranged on the upper surface of the lower guide plate 50.
The mark 51 is marked so that the position where the sheet is placed according to the size of the sheet such as 3 can be known.

The upper guide member 52 of the manual paper insertion guide 48 has a plate shape protruding forward at a thickness of about 5 mm and is provided horizontally. The front edge 54 of the upper guide member 52 has a central portion 53 forward with respect to the maximum sheet width (for example, the left and right width of A0 (841 mm), the left and right width of A1 (594 mm), etc.) and the minimum length of the sheet ( For example, the leading end of a vertically fed postcard size paper) is
4 is an arc curve protruding by a length (for example, about 50 mm) that can reach the position No. 4. Therefore, the slope of the tangent is
It is larger at the end. That is, the angle between the left and right directions is larger toward the end.

It is preferable that the vertical height of the sheet insertion opening 42 (the distance between the lower guide member 50 and the upper guide member 52) is smaller. This is because paper can be more easily inserted while performing curl correction with higher precision. Also, the smaller the distance, the less the possibility that a small curl enters the insertion port as it is. Also, there is a small possibility that something other than the paper enters and gets caught in the transport roller 44. However, since there is an assembly error, it is set to 3 mm by design. That is, for example, there is an assembly error of about ± 1 mm.
Since the distance of mm remains, the distance does not close.

[0013] With this configuration, the user can:
In the case of using the manual paper, as shown in FIG. 1, the manual paper 56 is formed by using the mark 51 according to the size.
It is placed on the lower guide member 50 and the manual feed paper 5
6 is connected to the central portion 5 of the upper guide member 52.
3 and the lower guide member 50. And
The sheet 56 is advanced as it is. Then, the curled portion 58 of the manual paper 56 is moved to the front edge 5 of the upper guide member 52.
In the case of No. 4, when the sheet 56 is further advanced, the curl portion 58 is corrected. In this manner, all the curled portions 58 are corrected and enter the lower side of the upper guide member 52, and in this state, are sandwiched by the transport rollers 44 and the transport path 4
6 is conveyed.

Next, in FIG. 4, the contents of the document conveyed by the conveying rollers 6 and 8 are written by the optical system 28 onto the photosensitive drum 30 charged by the charging charger 32 to form a latent image, and the developing roller 34 Is developed. Then, the toner image is transferred by the transfer charger 36.
The image is transferred to the manual paper 56. Then, the sheet 56 is separated from the photosensitive drum 30 by the separation charger 38 and sent to the fixing device 24, and the sheet 56 on which the toner is fixed is
The sheet is discharged from the copying machine 2 through a sheet discharge port (not shown).

Since the upper guide member 52 is a plate having a thickness of about 5 mm, the upper guide member
The curl portion 58 closer to the end than the portion abutting the second edge 54 can be wrapped around the upper guide member 52 as it is while the curl is still maintained. Therefore, the curl can be gradually corrected, and the curl can be corrected without any difficulty. Further, since the inclination of the tangent line of the edge 54 of the upper guide member 52 becomes larger toward the end, the straightening speed becomes lower as the curl at the end is further reduced.

In the case of inserting a manual paper having a wide left and right width wound into a roll into the manual paper insertion slot, if the center of the leading end is pressed by hand, the left and right portions naturally curl greatly. The work of inserting the paper is very complicated. However, even in the case of such a sheet, if the edge 54 of the upper guide member 52 retreats rearward as it advances toward both ends as in the present invention, the center of the leading end of the sheet is guided to the lower guide. If only the paper is positioned between the member 50 and the upper guide member 52 and the paper is thereafter moved forward,
Curls can be corrected naturally.

Next, a second embodiment of the present invention will be described. In FIG. 3, the edge 64 of the upper guide member 62 is
It is straight. Other configurations are the same as those of the first embodiment. Therefore, the front edge 6 from the central portion 63 to the edge portion
The inclination of the tangent line 4 is equal at any position.
Therefore, the central portion 63 of the upper guide member 62 is sharper than in the case of the first embodiment, and the central portion of the leading end of the sheet is formed by the central portion 63 of the upper guide member 62 and the lower guide member 60. The work of sandwiching between them is easier.
