DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for an image reading apparatus such as an image forming apparatus, a facsimile, a scanner, a printing machine, an ATM, a banknote counter, a ticket vending machine, a ticket gate, and the like, particularly an image forming apparatus such as a copying machine. The present invention relates to a transport cleaning method and a transport cleaning device for an image reading device.

[0002]

2. Description of the Related Art An image forming apparatus such as a copying machine is provided with an image reading device for reading an image on a document. The originals are placed one by one or in an insertion slot or an auto document feeder or ADF with a plurality of sheets stacked, and when read, separated one by one using a friction member such as a paper feed roller. It is conveyed to a reading device and read optically or electronically. In general, the paper sheet is conveyed by a pressing force at which the paper sheet is pressed by the friction member and a frictional force generated by a friction coefficient between the paper sheet and the friction member.

As shown in FIG. 15, a document is conveyed by a copying machine or a book scanner between a contact glass 101 serving as a document reading surface and a belt 102 facing the contact glass 101. Paper 103
, The paper 103 is conveyed while being pressed against the contact glass 101 by the belt 102, and an image on the paper 103 is read by a well-known optical system (not shown) located below the contact glass 101. In this case, the paper 103 is conveyed by the frictional force of the belt 102, and the paper 103 and the contact glass 101 are slipping. The belt 102 contacts the contact glass 101 and moves while rubbing the contact glass 101 when the paper 102 is not conveyed. Contact glass 101
The paper is constantly rubbed by the conveyor belt 102 or the paper 103. Therefore, foreign matter such as dust and paper dust attached to the belt 101 is rubbed against the contact glass 101, and the paper 103 directs the characters and images to be read toward the contact glass 101, so that the pencil or ink Cleaning of the transport path is important due to phenomena such as rubbing of the contact path on the contact glass.

[0004]

In an image reading apparatus, it is required to avoid a double feed in which two or more sheets of a document are not fed or a single sheet is fed, and to reliably feed one sheet. Further, even if the paper can be fed, it is not desirable that the paper is jammed, that is, the paper jam occurs in the transport path until the paper is discharged. However, daily use increases the number of occurrences of non-feeding, double feeding, and paper jams when used for a long period of time.

[0005] These non-feeds, double feeds and paper jams cause friction,
It is thought to be caused by paper curl and static electricity. The decrease in the frictional force is caused by the decrease in the coefficient of friction between the friction member and the sheet, thereby reducing the conveyance force, and the adhesion of foreign matter to the conveyance path increases the resistance to the sheet conveyance. The static electricity attracts the paper to the transport path and increases the transport resistance. In order to prevent these inconveniences, it is important to remove foreign substances and static electricity attached to the friction member.

In order to remove the dirt from the transport roller, a paper having a relatively weak adhesive applied to its surface, that is, a cleaning sheet is passed instead of a normal transfer paper to remove foreign substances by adhering to the cleaning sheet. That
This is disclosed in JP-A-5-85636 and JP-A-5-92834. Although cleaning is exemplified in the image forming process, they can also be used in the original reading process.

[0007] However, these techniques are proposals relating to a mechanism for sandwiching and transporting a sheet solely between rollers, and the transport rollers and the like become clean, but in particular, A is used in a document reading section of a copier or a book scanner.
Rather than transporting the paper sandwiched between rollers as in DF, the paper is transported by the frictional force between the paper and the belt pressed against one side of the paper, and the other side of the paper slides on the reading glass etc. No cleaning means having such a mechanism has been proposed. In particular, if a writing medium such as a pencil or ink adheres to a reading surface of an image on which a reading surface of a sheet slides, the reading performance may be reduced even if a conveyance failure such as a non-feeding jam does not occur.

In an apparatus having a cleaning mechanism incorporated therein, a mechanism for cleaning dirt on the cleaning member is important. If the maintenance mechanism is complicated, it is difficult to maintain a favorable state of the transport path.

As described above, there is a demand for a mechanism for transporting a sheet on a fixed surface by belt transport, which is simple in maintenance and capable of performing reliable cleaning.

SUMMARY OF THE INVENTION In view of the above problems, the present invention is capable of cleaning foreign substances on a belt surface or an image reading surface mainly in a mechanism for transporting paper by a surface such as a belt.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The transport cleaning method of the present invention will be described with reference to FIG. The present invention relates to a contact glass 1 serving as a document reading unit and a contact glass 1
Belt 3 as a friction member for feeding and transporting the sheet to the image reading device 3 having a known optical system reading device (not shown) located below the contact glass 1. Using a cleaning sheet 4 as a cleaning member made of an adhesive applied to the outer peripheral surface of the sheet,
This is for cleaning the contact glass 1 and / or the transport belt 2. In FIG. 1, the cleaning sheet 4 is used for cleaning the contact glass 1 and the conveyor belt 2, but may be used for cleaning either one of them.

The image reading apparatus 3 is provided in an electrophotographic image forming apparatus 5 as a well-known copying machine as shown in FIG. An image on a document supplied and conveyed by a well-known ADF is read by a reading device. The cleaning sheet 4 is set on a well-known document table (not shown) on which a document supplied to the contact glass 1 is normally placed, and by pressing a copy start switch S (see FIG. 2), the cleaning belt 4 is moved. Is supplied and conveyed toward the contact glass 1.

Since the cleaning sheet 4 is in the form of an endless belt, the conveyance belt 2 moving in the direction of arrow A repeatedly attracts and separates the conveyance sheet 2 and the contact glass 1 from each other. Move in Road 6. At the same time, the cleaning sheet 4 cleans the contact glass 1 and the transport belt 2 with the adhesive applied to the outer peripheral surface. Normally, the transport path 6 is configured so that only one sheet of paper is transported, so that a roller having a thickness other than a sheet cannot be transported, but the cleaning sheet 4 is formed of a soft member. So there is no problem in transportation.

If the cleaning sheet 4 is not an endless belt but a single sheet, the contact area with the contact glass 1 and the conveyor belt 2 is large, so that the frictional resistance due to the adhesive becomes very large. However, the cleaning effect cannot be satisfactorily exhibited due to, for example, a state in which the cleaning sheet 4 is stuck to one of the contact glass 1 and the transport belt 2. Does not happen.

The cleaning sheet 4 is transported along the transport path 6 in the same manner as ordinary paper, and both the contact glass 1 and the transport belt 2 are cleaned at the same time. The cleaning sheet 4 is formed by rolling a thin sheet having a surface coated with an adhesive into a cylindrical shape.

FIG. 2 shows an embodiment of the transport cleaning apparatus to which the present invention is applied. In this embodiment, the transport cleaning device 6 is an image forming apparatus in which a document cover 7 provided with a transport belt 2 forming a part of an ADF (not shown in detail) is opened upward for cleaning the contact glass 1. 4, which is detachable with respect to 4 and is attached by a pair of attachment members 8.

The mounting member 8 includes a fixed portion 9 that is partially dropped into the image forming apparatus 4 and a swing portion 1 that is swingably supported at one end of the fixed portion 9 that is exposed in the dropped state.
The recess 13 is formed so as to engage with a projection (not shown) provided on the image forming apparatus 4 side so that it does not easily come off when dropped into the image forming apparatus 4.

The rectangular frame 12 of the transport cleaning device 6 has steps 11 on both side edges. When cleaning is performed by the transport cleaning device 6, the document cover 7 is opened, the transport cleaning device 6 is positioned at a predetermined position above the contact glass 1, and then the fixing member 9 is dropped to form the image forming member 8. The transport cleaning device 6 is fixedly attached to a fixed position by attaching to the apparatus 1 and engaging the swinging section 10 with the step section. The oscillating portion 10 is urged by a spring (not shown) provided inside the mounting member 8 so as to press the step portion 11 toward the contact glass 1 side. Absent.

When the cleaning start switch (not shown) is depressed in a state in which the cleaning device 15 is attached to a fixed position, the transport cleaning device 6 moves the cleaning roller 15 as a cleaning unit having an adhesive applied to the outer peripheral surface thereof to a frame. The contact glass 1 is moved relative to the contact glass 1 along a pair of long holes 14 provided on the inner surface of the body 12 to clean the contact glass 1. As described in FIG. 1 regarding the description of the transport cleaning method, when one sheet is used for cleaning, the frictional resistance due to the adhesive is extremely large because the contact area with the contact glass and the transport belt is large. In the present invention, cleaning is performed using the cleaning roller 15 in the present invention.

FIG. 3 shows the cleaning roller 15 provided inside the frame 12 shown in FIG.
5 shows a moving means 16 for relatively moving with respect to. The moving means 16 includes a pair of motors 18 as rotation driving means for rotatably supporting both ends of the cleaning roller 15 by a shaft 17 of the cleaning roller 15, and the cleaning roller 15 via the motor 18 by the elongated hole shown in FIG. And a pair of shafts 20 and 20 ′ for moving the pair of belts 19 horizontally.
And a motor 21 for driving the shaft 20 to rotate.

Since the moving means 16 has such a structure, when the cleaning start switch is pressed in a state where the transport cleaning device 6 is mounted at a fixed position, the motor 21 rotates and the cleaning roller 15 is brought into contact with the contact glass. It is moved relative to 1, specifically, reciprocated. At this time, the motor 18 is connected to the cleaning roller 1.
5 is rotationally driven in a direction opposite to the direction in which it rotates with its relative movement with respect to the contact glass 1.

That is, when the motor 21 drives the shaft 20 to rotate clockwise as shown by the arrow C and moves the cleaning roller 15 together with the belt 19 in the direction of the arrow D, the motor 18 rotates the cleaning roller 15 in the direction indicated by the arrow E. When the cleaning roller 15 is driven to rotate in the clockwise direction and the motor 21 drives the shaft 20 to rotate in the counterclockwise direction indicated by the arrow F and the cleaning roller 15 is moved together with the belt 19 in the direction of the arrow G, the motor 18 rotates the cleaning roller 1 in the direction of the arrow. It is driven to rotate clockwise as indicated by the H direction. The shaft 20 ′ is
However, the shaft 20 'may be provided with another motor, and if the belts 19, 19 are separately driven, the shafts 20, 20' become unnecessary.

As shown in FIG. 4, the motor 18 is

As shown in FIG. 5, the fixing member 22 for fixing the motor 18 may be reciprocated by pulling the fixing member 22 with the wire 23. The fixing member 22 is slidable by a pair of cylindrical guide rods 24, and slides along the guide rods 24 by an annular wire 23 wound around a wire drive pulley (not shown) once. The pair of guide rods 24 is
This is because the fixing member 22 does not tilt.

As shown in FIG. 6, if a key 25 which engages with a key groove provided in the guide rod 24 is provided, or if the guide rod is formed into a prismatic shape (not shown), the guide rod 24 becomes one. Alternatively, the motor 18 may be provided with wheels 26 as shown in FIG.

FIG. 8 shows another embodiment of the moving means. The moving means 27 includes a pair of pinions 28 provided at both ends of the shaft 17 of the cleaning roller 15, and a pinion 28.
A pair of gears 29 always engaged with the gear 29, a rack 30 engaged with the gears 29, and reciprocating means (not shown) for rotatably supporting the shaft 17 outside the pinion 28 and reciprocating the cleaning roller 15. ing. The gear 29 is supported by the frame 12. In FIGS. 3, 4, 5, 6, and 7, the reciprocating means may have a configuration in which the motor 18 simply supports the shaft 17 so as to be rotatable.

According to the moving means 27, cleaning is performed by reciprocating the cleaning roller 15 in the horizontal direction along the elongated holes 14 shown in FIG. On this occasion,
The rack 30, the gear 29, and the pinion 28 rotationally drive the cleaning roller 15 in a direction opposite to the direction in which the cleaning roller 15 is rotated by its relative movement with respect to the contact glass 1. In this case, the relationship between the moving direction and the rotating direction of the cleaning roller 15 is the same as the relationship already described with reference to FIG. Cleaning roller 15
The rotation direction can be appropriately set by the number of gears disposed between the rack 30 and the pinion 28, and the rotation speed can be appropriately set by the diameter of the gears and the pinion.

As described above, in the embodiment of the transport cleaning device, as shown in FIG. 9, the rotation direction of the cleaning roller 15 is set to the J direction which is opposite to the direction in which the cleaning roller 15 moves along with the contact glass 1 by moving in the I direction. By forcibly rubbing the cleaning roller 15 and the contact glass 1, the cleaning is performed strongly with a force larger than the mere adhesive force of the adhesive, and the dirt is removed from the contact glass 1.
Has been shown to be able to cope with the case where it adheres for a long time, or causes a certain chemical reaction, and adheres very firmly, as shown in FIG.
The direction K may be the direction that follows the contact glass 1 by the movement in the direction I. In this case, unless the cleaning roller 15 is actively driven to rotate,
The motor 18 is not necessarily required, and the shaft 17 may be rotatably supported on the belt by a suitable means known in the art.

The cleaning means removes foreign matter such as dust and paper dust adhering to the cleaning roller 15 by applying a blade 31 shown in FIG. 11 in contact with the peripheral surface of the cleaning roller 15 or an adhesive shown in FIG. It may be provided with a roller 32 applied.

The roller 32 desirably rotates in the same direction as the cleaning roller 15 in order to efficiently clean the cleaning roller 15.
As shown in FIG. 5, the roller 32 and the contact glass 1 can be brought into contact with the contact glass 1 together with the cleaning roller 15 so that the roller 32 and the contact glass 1 rotate in a direction opposite to the direction in which the cleaning glass 15 rotates. Since the cleaning roller 15 and the cleaning roller 15 move in opposite directions at the respective contact positions, the cleaning efficiency is improved. As shown in FIG. 14, a blade 33 for cleaning the roller 32 can be brought into contact with the roller 32. The blades 31 and 33 are supported by a frame, and the roller 32 is supported by a configuration similar to the above-described configuration for supporting the cleaning roller 15.

If the positions where the blades 31, 33 and the roller 32 are installed are such that the removed foreign matter 34 collects on the upper and upper surfaces of the blades and rollers as shown in FIGS. The contact glass 1 is prevented from dropping and adhering, and foreign matter is easily removed. The rotation of the cleaning roller 15, the rotation of the roller 32, the contact / separation state of the blade, and the like are controlled so that the cleaning roller 15 or the like is moved only in one direction so that the soil once cleaned does not adhere to the contact glass or the like again. You may do it. Blade 31,
The roller 32 may be in contact with the cleaning roller 15 as needed.

In the embodiment of the transport cleaning apparatus, an example of cleaning the contact glass 1 has been described.
In order to clean the transport belt 2 provided in the ADF shown in FIG. 2, a transport cleaning device 6 may be attached to the document cover 7. The configuration for attachment can be the same as when the contact glass 1 is cleaned. Since the transport belt 2 can be driven, if the transport belt 2 is driven, it is not always necessary to provide a driving unit for the cleaning roller.

The transport cleaning device used in the image forming apparatus of the type in which the contact glass 1 moves does not necessarily need to have a driving means for the cleaning roller. When the contact glass 1 is to be cleaned, the original cover 7 is unnecessary. Therefore, after the original cover 7 is removed, the transport cleaning is usually performed using a member in which the original cover 7 is attached to the main body of the image forming apparatus 5. The device 6 may be attached.

To facilitate removal of the cleaning roller 15, the roller 32, and the blades 31, 33, it is possible to recover and maintain the cleaning performance and prevent the deterioration thereof by removing dirt adhered after the removal. It is preferable because it becomes easy. Combinations of the rotation direction of the cleaning roller 15, the roller 32, the installation positions of the blades 31, 33, the roller 32, and the like are not limited to those described above, and can be freely combined within the scope of those skilled in the art.

In the above embodiment, the present invention is applied to an image reading apparatus of an electrophotographic image forming apparatus as a copying machine. However, the present invention is not limited to this. Others, within the scope of those skilled in the art,
Fax, scanner, printing machine, ATM, banknote counter,
