Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material discharging apparatus for discharging and conveying a sheet material on which an image is recorded, and a recording apparatus having the same.

[0002]

2. Description of the Related Art A recording device having functions such as a printer, a copying machine and a facsimile, or a recording device used as an output device of a composite electronic device or a workstation including a computer, a word processor and the like is based on image information and is made of paper or plastic. An image is recorded on various sheet materials such as a thin plate. These recording devices are classified into an inkjet system, a wire dot system, a thermal system, a laser beam system, and the like depending on the recording system.

Of the above-mentioned recording methods, an ink-jet recording apparatus (inkjet recording apparatus) performs recording by ejecting ink from a recording unit (recording head) onto a sheet material, and the recording unit is made compact. Easy, high-definition images can be recorded at high speed, and can be recorded on plain paper without requiring special processing,
Since the running cost is low and the non-impact method is used, there are advantages that there is little noise and that it is easy to record a color image using multicolor ink.

In such an ink jet recording apparatus, the sheet material fed by the feeding means is held by the flat platen in the recording area, and the image is recorded by the recording head held by the carriage as the holding means. After that, the sheet is discharged and transported by the discharging means provided on the downstream side in the transport direction. In the discharge means, usually, a plurality of pressure contact rollers that are in contact with the image surface side of the sheet material are juxtaposed in a direction orthogonal to the sheet conveying direction, and the pressure contact rollers are constantly in pressure contact with the discharge roller, whereby Sheet material is nipped and conveyed.

[0005]

However, in the above-mentioned conventional example, the state of the sheet material after image recording may be different depending on the type (characteristic) of the sheet material, which may cause the following problems. .

For example, when a sheet material such as plain paper that easily absorbs ink is used, the sheet material is likely to be wrinkled or wrinkled due to the ink penetrating, or the ink is received on a base such as a polyester film. When a sheet material such as OHP paper coated with layers is used, the film itself does not absorb the ink, so that waviness does not occur, but there is a problem that it takes time to dry the ink.

As described above, in the case of a sheet material whose paper surface may wavy after image recording, the image surface side of the sheet material is constantly pressed by the pressure contact roller to prevent the sheet material from floating in the recording area. It was necessary to prevent the sheet material from rubbing against the recording head to stain the image or damage the recording head.

On the other hand, in the case of a sheet material on which the ink is hard to dry, the pressure contact roller contacts the image surface of the sheet material before the ink on the image surface dries, so that the ink on the image surface adheres to the pressure contact roller. In addition, when the pressure contact roller makes one rotation, the ink attached thereto may be transferred to the image surface of the sheet material, which may cause image contamination.
In order to prevent this, it is conceivable to provide a cleaning means for wiping off the ink adhering to the pressure contact roller, but this increases the cost and even if the cleaning means is provided, the ink adhered to the pressure contact roller is completely removed. It was difficult to wipe it off.

The present invention has been made in view of the above problems, and an object thereof is to prevent problems caused by the state of a sheet material after image recording which differs depending on the type (characteristic) of the sheet material. .

[0010]

A typical structure of the present invention for achieving the above object is to provide a drive rotating body and the drive rotation in a sheet material discharging device for discharging and conveying a sheet material having an image recorded thereon. A plurality of driven rotating bodies that are driven to rotate by being pressed against the body, and the driven rotating body is configured to abut or separate from the drive rotating body according to the type of sheet material. Characterize.

According to the above construction, the driven rotary body is brought into contact with or separated from the drive rotary body according to the type of the sheet material. Therefore, the conveying method according to the characteristics of each sheet material can be adopted. You can choose. For example, when the sheet material easily absorbs the ink, the driven rotating body is brought into contact with the driving rotating body to prevent the sheet material from floating up by controlling the corrugation of the sheet material,
Further, when the sheet material does not easily absorb the ink, at least the driven rotating body disposed in the recording image area is separated from the driving rotating body to prevent the ink of the sheet material from adhering to the driven rotating body. be able to.

Here, the structure of the discharge part 4 according to the present invention will be described in detail with reference to FIGS. 4 and 5. As shown in FIGS. 4 and 5, of the driven rotor, the spur 42 is disposed in the recording image area of the sheet material S, and is attached to the discharge roller 41 according to the type (characteristic) of the sheet material S. It is configured to be able to contact or separate from each other.

The spur 42 is attached by a spring 45 to a support member 44 which is attached to an exterior member (not shown) so as to be movable up and down (in the direction of the arrow in the figure), and when contacted with the sheet material S as shown in FIG. The spring 44 bends to generate an appropriate pressure. A slide member 46 for switching the position of the spur 42 with respect to the discharge roller 41 (the contact position shown in FIG. 4 or the separated position shown in FIG. 5) is provided on the exterior member.

The slide member 46 is provided with a slide arm 46a for sliding the member 46 in the direction of the arrow in the drawing, and a cam portion 46b for vertically moving the support member 44, and the cam portion 46b is provided with the cam portion 46b. A protrusion 44a provided on the support member 44 is engaged. Therefore, by sliding the slide member 46 in the direction of the arrow in the figure, the support member 44 moves up and down in the direction of the arrow in the figure. That is, the sheet material S
By sliding the slide member 46 according to the type (characteristic), the spur 42 is brought into contact with the discharge roller 41 as shown in FIG. 4, or the discharge roller 41 as shown in FIG.
It can be separated from 41.

Of the driven rotary member, the discharge roller 43 is arranged outside the recording image area of the sheet material S, and is in constant contact with the discharge roller 41 as shown in FIGS. 4 and 5. Has become. The discharge roller 43 is attached to the above-mentioned exterior member (not shown) with a spring 45.
By the appropriate pressure generated by the bending of the sheet material S
Is pressed against the discharge roller 41. Therefore, for example, the spur
Even when 42 is separated from the discharge roller 41, both ends of the sheet material S are pressed against the discharge roller 41 by the discharge rollers 43, so that the sheet material S can be conveyed well.

As shown in FIGS. 4 and 5, among the driven rotors, the spur 42 disposed in the recording image area of the sheet material S has a small contact area with the sheet material S (the present embodiment). In the form, it is formed as a thin plate such as a gear-shaped plastic or metal having a pointed tip, and the discharge roller 43 arranged outside the recorded image area of the sheet material S has a large contact area with the sheet material S. (Elastomer or metal roller)
It is formed as. As a result, ink hardly adheres to the spur 42 that rotates by contacting the image surface of the sheet material, and the sheet can be satisfactorily conveyed by the discharge roller 43 and the discharge roller 41 excluding the spur 42.

With the above-described structure, the sheet material S on which an image is formed by the carriage portion 5 is nipped and conveyed by the discharge roller 41, the spur 42, and the discharge roller 43, or the discharge roller, depending on its state. It is conveyed by being sandwiched between 41 and the discharge roller 43 and discharged onto a discharge tray (not shown).

Next, the operation of the discharging section 4 when the state of the sheet material after image formation is different depending on the type of the sheet material (sheet material having good ink absorption, sheet material where ink is hard to dry) will be described. To do.

When the sheet material is a sheet material such as plain paper having a good ink absorption, as shown in FIG. 4, the spur 42 is discharged from the discharge roller in order to regulate waviness and wrinkles on the paper surface. The sheet 41 is brought into contact with 41 to form a nip portion for sandwiching and conveying the sheet material S between the discharge roller 41 and the spur 42 and the discharge roller 43. Thereby, the sheet material S after the image recording
Since it is possible to regulate waviness, wrinkles, and the like on the sheet of paper, it is possible to prevent the sheet material S from rising in the recording area. Therefore, it is possible to prevent image stains, damage to the recording head, and the like, which are caused by the sheet material S rubbing against the recording head 7.

On the other hand, when the sheet material is a sheet material such as a polyester film having a receiving layer coated on a base and the drying property of the ink is not so good, the spur 42 is discharged as shown in FIG. The sheet material S is nipped and conveyed only at the nip portion formed between the discharge roller 41 and the discharge roller 43 while being separated from the roller 41. As a result, the spur 42
An image in which the tip of the sheet peels off the receiving layer soaked with ink and the ink is attached to the tip, and the ink attached after one rotation is transferred to the image surface of the sheet material S, leaving a spur mark. It can prevent dirt.

In the case of a sheet material on which the ink is hard to dry, no waviness or wrinkles on the paper surface due to the absorption of the ink is generated. Therefore, it is sufficient to press both end portions outside the recording image area without pressing the image surface of the sheet material S. It is enough.

However, at this time, the corrugation of the sheet material does not occur, but the sheet material may be lifted up for some reason. Therefore, as shown in FIG. A configuration may be adopted in which the direction is inclined outward by an angle θ with respect to the direction. As a result, the sheet material S nipped and conveyed by the discharge rollers 43 and the discharge rollers 41 is applied with the tension t directed outward in the width direction, so that the spur 42 is separated and the sheet is separated as shown in FIG. Even if the material is lifted, the lift of the sheet S can be prevented and good image recording can be performed in the recording area.

[Other Embodiments] In the above embodiment, in the case of a sheet material having poor dryness, the spurs 42 contacting the inside of the recorded image area of the sheet material are retracted from the start of recording to the end of recording (discharge roller 41). However, the present invention is not limited to this. However, the present invention is not limited to this, and the sheet material is discharged and conveyed by pressing the discharge roller 43 that is in contact with the outside of the recording image area of the sheet material.

For example, as shown in FIGS. 7 to 9, when the spur as a driven rotating body for pressing the sheet material and the discharge rollers are initially retracted and the rear end portion of the sheet material is discharged and conveyed. The spur may be brought into contact with. In the apparatus shown in the figure, a plurality of spurs 42 as driven rotors are arranged side by side over the entire width direction of the sheet material (direction orthogonal to the conveying direction), and the spurs 42 can move up and down in the direction of the arrow in the figure. Attached to the support member 44 by a spring 45. The protrusion 44a provided on the support member 44 engages with the cam portion 46b of the slide member 46 which is slidable in the direction of the arrow in the figure. Then, at both ends in the width direction of the slide member 46, the arm portions 46c protruding into the moving area of the carriage portion 5,
46d are provided respectively. Therefore, when the arm portion 46c is pushed by the movement of the carriage portion 5 in the direction of the arrow B, the spur 42 comes into contact with the discharge roller 41 (see FIG. 7), or the arm portion 46d is moved by the movement of the carriage portion 5 in the direction of the arrow C. When is pressed, the spur 42 is separated from the discharge roller 41.

In the apparatus having the above-mentioned structure, when the sheet material is a sheet material such as plain paper having good ink absorption, as shown in FIGS. The sheet material S is pressed and the sheet material S is nipped and conveyed in cooperation with the discharge roller 41.

On the other hand, when the sheet material is a sheet material in which the receiving layer is coated on the base such as a polyester film and the drying property of the ink is not so good, a switch (not shown) or a host computer for sending image data is used. The signal identifies the type of sheet material in the device.

Then, when the leading edge of the fed sheet material S is detected by the PE sensor 32 and the PE sensor lever 35 (see FIG. 9) and is conveyed to a predetermined recording start position, FIG. 8), the carriage portion 5 pushes the arm portion 46d of the slide member 46 in the direction of arrow C in FIG. 8 to slide the slide member 46 in the same direction. As a result, the support member 44 is pulled up, and the spur 42 attached to the support member 44 is separated from the discharge roller 41 as shown in FIGS. 8B and 9A.

After that, an image is recorded on the sheet material S, and before the trailing end of the sheet material S passes through the nip portion of the conveying roller pair 36, 37, as shown in FIG.
42 is at a retracted position separated from the discharge roller 41. Here, when the rear end portion of the sheet material S reaches the nip portion of the pair of conveying rollers 36 and 37, the carriage portion 5 moves the arm portion 46c of the slide member 46 to the arrow in FIG. 7 as shown in FIG. 7A. Push in the B direction to slide the slide member 46 in the same direction. As a result, the support member 44 is pushed downward, and the spur 42 attached to the support member 44 is moved to the position shown in FIGS.
As shown in (b), the sheet material S is nipped and conveyed by contacting the discharge roller 41.

Here, as shown in FIG. 9B, the diameter of the spur 42 is D, and the nip portion a of the pair of conveying rollers 36, 37 is a.
When the length between the discharge roller pair 41 and 42 and the nip portion b of the discharge roller pair is L, the relationship between the two is πD> L. Therefore, even if the spur 42 comes into contact with the image surface of the sheet material and the ink adheres when the sheet material S is nipped and conveyed by the pair of discharge rollers 41 and 42 at the rear end portion of the sheet material S, the spur 42 still remains. Since the rear end of the sheet material S has passed through the nip portion b of the discharge roller pair 41, 42 after one rotation, the ink adhering to the spurs 42 is not transferred to the image surface of the sheet material S. Absent.

A cleaner 41a is attached to a portion of the discharge roller 41 which is in contact with the spur 42.
The ink adhering to the spur 42 is wiped off before the next sheet material is fed.

Therefore, even with the above-mentioned structure, it is possible to select the conveying method according to the characteristics of the sheet material, and similar to the above-described embodiment, a problem occurs depending on the state of the sheet material after image recording. (Image stains and the like) can be prevented.

Further, in the above-mentioned embodiment, an example in which the present invention is applied to a recording apparatus provided with a serial type recording head for recording while scanning in the width direction of the sheet material is shown.
The present invention is not limited to this, and the present invention can be effectively applied to a recording apparatus including a full-line type recording head having a length corresponding to the maximum width of a sheet material that can be recorded by the recording apparatus. Such a recording head may have a configuration that satisfies the length by combining a plurality of recording heads, or a configuration as a single recording head that is integrally formed.

In addition, even in the case of the serial type described above, when the recording head is fixed to the carriage or mounted on the carriage, it is possible to electrically connect to the apparatus main body and supply ink from the apparatus main body. A replaceable chip type recording head may be used.

Regarding the type and number of recording heads mounted on the carriage, for example, only one recording head is provided corresponding to a single color ink, or a plurality of inks having different recording colors and densities are supported. And a plurality of them may be provided. That is, for example, the printing mode of the printing apparatus is not limited to a printing mode of only a mainstream color such as black, and may be a printing head integrally configured or a combination of a plurality of printing heads.
