The control unit 21 is used as a work area of the CPU 21a1 for controlling the entire apparatus, a ROM 21a2 for storing various programs and various data, and the like, and temporarily stores various data such as the number of recordings. It has a RAM 21a3 and an input / output switching interface 21a7 for separating a facsimile from a printer.

In the case of transmitting or copying a document, one line of image data from the optical reading system 3 is stored in the line memory 21a4 for storing the image of each line of the image data. In this case, one line of combined data is stored. The image data stored in the line memory 21a4 is added with a recording system control code through the CPU 21a1 and output from the input / output switching interface 21a7 to the CPU 4a of the recording system 4, and the CPU 4a converts the recording system control code into the image data. By decoding, image recording is performed.

Next, control of the image recording function will be described. First, the data and the recording system control code sent from the peripheral computer are taken into the control unit 21 via the printer interface 21f1. Then, the image is output from the input / output switching interface 21a7 to the CPU 4a of the recording system 4, and the CPU 4a decodes the recording system control code to record an image. At this time, the control unit
The CPU 21a1 included in 21 is configured not to control the image recording. This simplifies the separation between facsimile and printer.

Next, the original is transmitted while the image received in the memory is being printed out, or
7 shows details of the movement of the document D and the recording sheet P when the reading operation and the recording operation are simultaneously performed, for example, when performing a direct copy operation in which a document is set and a recording operation is performed while the original is being read.

A plurality of documents D set on the document tray 9 with the reading surface facing down are separated and fed one by one by a separation roller 3c and a friction knit 3b pressed against the separation roller 3c, and are conveyed by a conveyance roller 3e and a conveyance roller 3d. And discharged out of the apparatus by discharge rollers 3g and discharge rollers 3f.
While the original D is being conveyed, the original D is irradiated with light by the close contact type image sensor 7 of the optical reading system 3 and the reflected light is converted into an electric signal to read image information.

As shown in FIG. 4, the details of the operation of separating the originals D one by one by the separating roller 3c and the friction piece 3b pressed against the separating roller 3c will be described. The lowermost document D (1) loaded on the document table 2a and the document tray 9 is a separation roller 3
c, the Nth original D (N) hits the friction piece 3b,
Other documents are sandwiched between these documents. In this situation, when the separation roller 3c rotates in the direction of the arrow,
The N-th original D (N) is caused by friction with the friction piece 3b,
From the original D (2) to the (N-1) th original D (N-1), the movement between the originals is hindered by the friction between the originals, so that the original is not conveyed, but is in contact with the separation roller 3c. Only the original D (1) is transported. The first document D (1) is conveyed while being rubbed with the second document D (2), and is charged with static electricity, and the static electricity is also accumulated in the second and subsequent document bundles that are not conveyed. .

When the first document D (1) has been conveyed, the second document comes to the bottom and comes into contact with the separation roller 3c. When the separation roller 3c rotates in the direction of the arrow again, the two Only the original of the eye is conveyed. Thereafter, the same operation as described above is performed until the stacked originals D disappear, and static electricity is accumulated in the unconveyed original bundle.

On the other hand, when the recording sheet P set on the sheet feeding tray 8 is fed to the recording system 4, the sheet separating roller 14c rotates in the feeding direction (clockwise direction in FIG. 2).
The recording sheet P is separated and fed one by one at a nip portion between the sheet separation roller 14c and the separation pad 14a which is in pressure contact with the sheet.

The recording sheet P separated and fed one by one from the sheet feeding device 15 is guided to the nip portion between the conveying roller 16a and the pressure contact roller 16c, is nipped and conveyed, and is moved between the photosensitive drum 12b and the transfer roller 12c. It is sent to the nip.

The photosensitive drum 12b is driven by an integrally mounted gear and rotates in the transport direction (clockwise direction in FIG. 2). A gear is also integrally attached to the transfer roller 12c, and is driven by meshing with the gear of the photosensitive drum 12b, and rotates in the counterclockwise direction in FIG. The toner image is transferred onto the surface of the recording sheet P sent to the nip between the photosensitive drum 12b and the transfer roller 12c by the above-described process.

The recording sheet P on which the toner image has been transferred is
It is transported to the heat fixing device 17. The pressure roller 17b rotates counterclockwise in FIG. 2, and a heater 17a is disposed at a position facing the pressure roller 17b. A film 17d is attached to the outer periphery of the heater 17a so as to be driven by the pressure roller 17b. Recording sheet P conveyed to thermal fixing device 17
Is guided to the nip portion between the pressure roller 17b and the film 17d, the image surface side is heated, and the toner image formed on the recording sheet P is fixed.

The recording sheet P on which the image has been fixed is guided to the nip portion of the discharge roller pair 18, and the discharge direction of the recording sheet P is switched between straight and U-turn depending on the direction of the flapper 19. When the flapper 19 is at the position shown in FIG. 2, the recording sheet P makes a U-turn through the guide section 20, is conveyed to the discharge roller pair 13 and is discharged from the discharge port 23, and the recording sheet discharge table 2b and the sheet discharge The sheet is discharged and loaded on the tray 10.

As described above, as described above, not only the friction between the recording sheets when the uppermost recording sheet is separated and conveyed one by one by the sheet feeding device 15 but also the image is recorded on the recording sheet P. Static electricity is also accumulated during contact with the film 17d during the process of forming the film thereon and the process of fixing the image.

The leading end of the recorded recording sheet P discharged to the recording sheet discharge table 2b is attracted in the direction of the original D by the static electricity accumulated in the bundle of originals D transported on the original tray 9 before being conveyed. However, since the recording sheet P cannot approach the original D due to the ribs 9a formed on the back surface of the original tray 9, the suction force generated by the static electricity accumulated on the recording sheet P and the original D is greatly reduced. be able to. The drawn recording sheet P comes into contact with the rib 9a, so that the original tray 9
The area in contact with the surface is reduced, and the generated static electricity is greatly reduced. Thus, it is possible to prevent the recording sheet P from being attracted to the back surface of the document tray 9.

Further, when the trailing end of the recording sheet P is discharged from the discharge port 23, the recording sheet P is stacked along the sheet discharge tray 10 by its own weight. Therefore, it is possible to prevent a jam from being caused without obstructing a discharge path of a recording sheet discharged thereafter, and it is possible to greatly improve reliability as a product.

In the above embodiment, the document tray 9
Base thickness is 2.5mm, rib height is 4.5m
m (about 1.8 times the basic thickness), but the present invention is not limited to this. Basic wall thickness 2m in experiment
If the height of the rib is as low as about 1.5 mm, suction may occur even if no jam occurs.If the height of the rib is about 3 mm (about 1.5 times the basic thickness), The effect of the invention could be obtained.

Here, the higher the rib, the greater the effect is because the attractive force by the electric charge is inversely proportional to the square of the distance.
The effect of the present invention can be obtained as long as the sum of the basic thickness of the document tray and the height of the rib is equal to or more than a predetermined amount.

[Second Embodiment] Next, a second embodiment of the image processing apparatus according to the present invention will be described. FIG. 5 is an external perspective view showing the overall configuration of the image processing apparatus according to the present embodiment. Parts that are the same as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the first embodiment, the document tray 9 is formed by providing the ribs 9a on the rear surface of the plate-shaped molding material. However, the stacked document D and the recorded recording sheet P are separated by a certain distance. The same effect can be obtained even if the document tray is constituted only by the ribs.

As shown in FIG. 5, in the image processing apparatus according to this embodiment, a document tray 24 composed of only ribs is provided on the document mounting table 2a of the cartridge cover 2. The operation of the document D and the recording sheet P in this apparatus is the same as that of the first embodiment,
Is composed of only the ribs, compared with the case where two trays are arranged close to the front of the apparatus main body 1, there is no feeling of pressure and a clear impression can be given to the user.

In this embodiment, the original tray 24
Is composed of two ribs, but may be composed of three or more ribs.

[Third Embodiment] Next, a third embodiment of the image processing apparatus according to the present invention will be described. FIG. 6 is an enlarged view of a document tray of the image processing apparatus according to the present embodiment. In the first and second embodiments, the ribs are used to separate the stacked originals D and the recorded recording sheets P. However, even if the plate-like portion of the original tray is formed in a step shape, the same is applied. The effect can be obtained.

The document tray 25 shown in FIG. 6 is formed of a molding material as in the first embodiment, and has a step 25a at a substantially central portion along the moving direction of the document D. As a result, similarly to the first and second embodiments, it is possible to prevent the recording sheet P from being attracted to the back surface of the document tray 25, and it is possible to prevent a jam when the recording sheet P is discharged.

In the sheet conveying apparatus according to each of the above-described embodiments, the document tray as the sheet stacking means before reading and the sheet discharge tray as the sheet stacking means after recording are arranged adjacent to each other. The effects of applying the present invention to a sheet conveying apparatus or an image processing apparatus in which these are rotated by 90 °, that is, the sheet stacking means before reading and the sheet discharging means after recording are arranged vertically adjacent to each other, are also available. Obtainable.

[0054]

As described above, the image processing apparatus according to the present invention has a rib or the like at the rear side of the stacking means located in front of the pre-read sheet stacking means and the post-recording sheet stacking means. Providing the separation means enables a predetermined distance between the sheet discharged to the rear loading means and the sheet loaded to the front loading means. Therefore, even when the discharged sheets are charged with static electricity of a voltage opposite to that of the stacked sheets, they do not approach each other more than the interval secured by the separation means, and the suction force due to the static electricity can be greatly reduced. it can. Further, the area of the sheet discharged by the separation means in contact with the stacking means on the front side is reduced, and the generated static electricity is greatly reduced. Thus, it is possible to prevent the discharged sheet from being attracted to the stacking means on the front side.

Therefore, it is possible to prevent the occurrence of a jam without significantly hindering the discharge of a sheet to be discharged later, thereby greatly improving the reliability of the product.
