Abstract

PURPOSE:To enable saving of a space by a method wherein a manual insertion feed device is mounted to the front of a machine body, and a manual insertion sheet is conveyed in a direction extending at right angles with a manual insertion direction. CONSTITUTION:When a manual insertion sheet S is inserted and placed on a manual insertion tray 21 along a side regulating plate 23 and a copy button is depressed, a conveyance belt 22 is started to rotate, and the sheet S is conveyed in a direction of an arrow mark A. When an end part is detected by a sheet end sensor 25, the deep part of the sheet S is situated in a position along a conveyance reference. A solenoid 31 is then turned ON, and through rocking of an arm 27a, a conveyance roller 30 is also rocked in the direction of an arrow mark B and brought into contact with the sheet A. A drive force is transmitted to the conveyance roller 30 through a shaft 26, a pulley 33, a belt 36, a pulley 35, and a shaft 29. The sheet S is conveyed in the direction of an arrow mark D and conveyed to a resist roller pair 6 through conveyance roller pairs 37, 39, and 40, and after a picture is duplicated, the sheet is discharged in a discharge tray 11.

A fixing device 10 is provided downstream of the belt 9, and a paper discharge tray 11 is provided downstream of the fixing device 10. Also, on the right side of the aircraft 2,
A manual feed tray 12 on which a manual receipt S is placed is provided, and a paper feed roller pair 13 is provided on the downstream side of the tray 12 to feed the manual receipt S to the registration roller pair 6. ing. On the other hand, the copying section 7 has a cylindrical photosensitive drum 15, and around the drum 15, a negative charger 16, a developer 17, a transfer charger 19, and a cleaner 20 are arranged. .

Then, the manual receipt S placed on the manual tray 12
is fed to the registration roller pair 6 by the paper feed roller pair 13, and is conveyed by the roller pair 6 in synchronization with the toner image on the photosensitive drum 15. Then, the image is transferred to the sheet S by the transfer charger 19, and the sheet S is conveyed to the fixing device 10 by the conveyor belt 9. Furthermore, the image is fixed on the sheet S by a fixing device 10, and the sheet S is discharged to a paper discharge tray 11.

(C) Problems to be Solved by the Invention By the way, in the above-mentioned copying machine 1a, the manual feed tray 12
is located on the right side of the machine body 2, so when placing the manual receipt S on the tray 12, sufficient space is required on the right side of the machine body 2, which is an obstacle to space saving.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an image forming apparatus that allows manual receipts to be inserted from the front of the machine, thereby solving the above-mentioned problems.

(d) Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances. For example, referring to FIGS. 1 and 3, manual receipts (
A manual feeding device (21,
22, 23), the manual feeding device (21, 22, 23) is connected to the body (
2) Manual receipt (S) installed on the front and inserted manually
The device is characterized in that it is configured to be conveyed in a direction perpendicular to the manual feeding direction.

(f) Function Based on the above configuration, the manual feeding device (21°22.23
) The sheet (S) that is manually fed into the manual feeding system r!
l(21, 22, 23), the paper is fed in a direction perpendicular to the manual feeding direction, an image is formed thereon, and the paper is discharged to the outside of the machine (2).

Note that the above-mentioned symbols are shown for reference and do not limit equivalent configurations.

(F) Examples Examples of the present invention will be described below with reference to the drawings.

Note that the same parts as those described above are given the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 2 and 3, the copying machine 1 is equipped with a manual feed tray 21 on the front side of the machine body 2 and below the cassette 3. A conveyor belt 22 for conveying the sheet S, and a side regulating plate 23 for regulating the sides of the sheet S are provided.

As shown in FIG. 1, the conveyor belt 22 is connected to a drive roller 22 driven by a drive means (not shown).
a and the driven roller 22b, and the belt 2
A sheet end sensor 25 is disposed on the back side of the sheet. Further, the side regulating plate 23 is configured to be able to slide in the direction of arrow E with respect to the manual feed tray 21, and can be moved in accordance with the sheet size. Further, on the right side of the conveyor belt 22, a shaft 26 is supported by the machine body 2, and the shaft 26 supports arms 27a, 27b.
is swingably supported. And these arm 2
A shaft 29 is rotatably supported by 7a and 27b, and a conveyance roller 30 is fixed to the shaft 29. Further, a solenoid 31 is connected to one end of the arm 27a, and on the opposite side of the solenoid 31, one end is connected to the body 27a.
A spring 32 fixed to is connected. Further, a pulley 33 is fixed to the shaft 26, and a pulley 33 is fixed to the shaft 29.
A pulley 35 is fixed to these pulleys 7 and 33.
A belt 36 is stretched around 35. Note that 37, 39, and 40 in FIG. 2 indicate a pair of conveying rollers.

Since this embodiment has the above-described configuration, when the operator inserts and places the manual receipt S on the manual tray 21 along the side regulation plate 23 and presses a copy button (not shown), the conveyor belt 22 rotates. The sheet S is conveyed in the direction of the arrow (see FIG. 1). Then, when the edge of the sheet S is detected by the sheet edge sensor 25, the conveyor belt 22 is stopped. As a result, the manual receipt S is positioned with the rear side aligned with the conveyance reference. Then, the solenoid 31 is turned on, and the arm 27a is moved by the spring 32.
It swings in the direction of arrow B (see Fig. 1) against the Furthermore,
As the arm 27a swings, the conveying roller 30 also swings in the direction of arrow B and comes into contact with the manual receipt S. 1. The driving force from a driving means (not shown) is transmitted to the conveying roller 30 via the shaft 26, pulley 33, belt 36, pulley 35, and shaft 29.
The roller 30 moves in the direction of arrow C (see Fig. 1).
Rotate to. Then, due to the rotation of the roller 30, the manual receipt S is conveyed in the direction of the arrow (see FIG.
transported to. Then, the image is copied on the sheet S by the same operation as described above, and the sheet S is discharged to the paper discharge tray 11.

In the above-mentioned embodiment, the manual receipt S was conveyed to the rear side of the machine body 2 by the conveyor belt 22, but the invention is not limited to this, and as shown in FIG. Due to the weight of the difference receipt S, the sheet S moves towards arrow A.
The tray 21' may have an abutment plate 21'a erected on the back side, and the manual receipt S that has slipped in the direction will be moved against the abutment plate 21'a. It comes into contact with and stops. At this time, when the sheet end sensor 25 detects the sheet S, the shaft 26' rotates in the direction of arrow F, and the sheet S is held between the roller 30'a and the conveyance roller 30'b. Then, when the roller 30'b starts rotating in the G direction, the manual receipt S is conveyed in the direction of the arrow, an image is formed thereon by the same operation as described above, and the sheet is discharged to the paper discharge tray 11.

(G) As described in detail, according to the present invention, the manual feeding device is provided at the front of the machine body and is configured to feed manually fed manual receipts in a direction perpendicular to the manual feeding direction. Therefore, no extra space is required on the right side of the fuselage, making it possible to save space.
