Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a printer, a copying machine,
The present invention relates to an image recording apparatus such as a facsimile machine or a printing machine, which records on a sheet by printing, transferring, copying, printing or the like.

[0002]

2. Description of the Related Art Conventionally, for example, in some laser printers,
As shown in FIG. 4, the sheet S in the sheet feeding cassette 1 is sent out by the rotation of the sheet feeding roller 2 and abuts against the pair of registration rollers 3, and the sheet is transferred while the timing of the pair of registration rollers 3 is set. After S is conveyed to the lower side of the photoconductor 4 and the image formed on the surface of the photoconductor 4 is transferred to the sheet S by the transfer device 5, the heating roller 6a and the pressure roller of the fixing device 6 are further transferred. 6
The transfer image on the sheet S is fixed through the space b, and the fixed sheet S is discharged from the discharge port 8 of the recording apparatus main body 7 and stacked on the discharge stack unit 9 in a face-down state with the recording surface facing downward. There are things I tried to do.

[0003]

However, in a printer that stacks in a face-down state, since the sheets S after recording are stacked in page order, it is necessary to change the page order of the sheets S picked up from the paper discharge stack section 9. Although there is no advantage, the recording surface faces downward, so the sheet S
When checking the recording state on the sheet, it is troublesome to manually turn over the discharged sheets on the discharged sheet stack section 9.

SUMMARY OF THE INVENTION An object of the present invention is to make it easy to check the recording state on a sheet when stacking face-down on a sheet discharge stack section.

[0005]

Therefore, according to the first aspect of the present invention, a printer for stacking sheets S after recording on the discharge stack section 12 in a face-down state, for example, as in the following illustrated embodiment. In an image recording apparatus such as the above, on the outer surface of the recording apparatus main body such as the printer main body 10,
With a confirmation window 13 that allows you to look inside,
A conveyance path 15 for conveying the sheet S after recording with the recording surface facing the confirmation window 13 is provided inside the confirmation window 13.

A second aspect of the present invention is characterized in that the confirmation window 13 is covered with a transparent member 25 in the image recording apparatus of the first aspect, for example, as in the following illustrated embodiment. .

According to a third aspect of the present invention, the transparent member 25 is detachable in the image recording apparatus according to the second aspect, for example, as in the following illustrated embodiment.

[0008]

According to the present invention, when confirming the recording state on the sheet S after recording, the recording surface of the sheet S facing the confirmation window 13 side is seen through the confirmation window 13.

According to the second aspect, the confirmation window 13 is closed by the transparent member 25.

According to the third aspect of the invention, the transparent member 25 is detached if necessary.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of the entire internal mechanism of a laser printer which is an embodiment of the present invention, and FIG. 2 is an external perspective view thereof.

Reference numeral 10 in the drawing denotes a printer main body. The printer body 10 has a box-shaped outer shape, and
The middle right side is the front part 10a and the left side is the back part 10b. In the front portion 10a of the printer body 10, a paper discharge port 11 is opened in the upper portion, and a paper discharge stack portion 12 is provided immediately below it. In addition, a confirmation window 13 through which the inside can be seen is provided at the upper and lower center of the front portion 10a.
The confirmation window 13 is covered with a transparent member 25.

The transparent member 25, as shown in FIG.
A plastic plate or a glass plate is used to form a horizontally long shape that is substantially the same as the confirmation window 13, and guide ribs 26 are provided along the left and right sides of the back surface thereof. The guide ribs 26 have an L-shaped cross section and are provided so as to face each other on the left and right.

Inside the confirmation window 13, as shown in FIG. 1, a conveyance path 15 for conveying the sheet S after recording is formed along the inner surface of the front surface 10a of the printer body 10. The transport path 15 is formed between the transport guide plates 14, one of which is connected to the outlet of the fixing device 16 and the other of which is connected to the paper discharge port 11. Further, in the printer main body 10, a photoconductor 17 is arranged substantially at the center, and a transfer device 18 is arranged thereon. A paper feed cassette 19 is detachably attached to the back surface portion 10b of the printer body 10.

When recording on the sheet S,
As shown in FIG. 1, the sheet S in the paper feed cassette 19 is fed out by the rotation of the paper feed roller 22 and abuts against the registration roller pair 23, and then the registration roller pair 23.
Then, the sheet S is conveyed to the upper side of the photoconductor 17 at a timing. Then, the image formed on the surface of the photoconductor 17 is transferred to the lower surface of the sheet S by the transfer device 18. The sheet S after the transfer is guided by a conveyance guide (not shown) and conveyed to the fixing device 16, where the heating roller 16a and the pressure roller 16a are pressed.
The transfer image on the sheet S is fixed by the la 16b. Then, the sheet S exiting the fixing device 16 passes through the conveyance path 15 with the recording surface facing the confirmation window 13 side, is discharged from the paper discharge port 11 and is face down to the paper discharge stack unit 12. To stack.

When it is desired to check the recording state on the sheet S after such recording, the recording surface of the sheet S is confirmed by a confirmation window 13.
Peek from

In the above embodiment, the confirmation window 13 is covered with the transparent member 25. In this case, the transparent member 2
It is convenient to attach 5 to the confirmation window 13 to make it detachable. When a jam occurs in the transport path 15, the transparent member 25 is removed to open the confirmation window 13, and the jammed paper is removed from the confirmation window 13. After the jam processing, the transparent member 25 is fitted to the confirmation window 13 again.

Further, the transparent member 25 may be constructed so as to be openable and closable, not removable.

[0019]

According to the present invention, therefore, when confirming the recording state on the sheet S after recording, it suffices to look through the recording surface of the sheet after recording facing the confirmation window. It is possible to easily confirm the recording state on the discharged sheet without the trouble of manually inverting the sheet as in the conventional case.

According to the second aspect, since the confirmation window is closed with the transparent member, it is possible to prevent dust from entering the main body of the recording apparatus through the confirmation window.

According to the third aspect of the present invention, the transparent member can be attached and detached. Therefore, for example, when a sheet after recording is jammed in the conveyance path, the transparent member is removed and the jammed paper is removed from the confirmation window. Therefore, the jam processing can be facilitated.
