Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for recording on a recording material, and more particularly, to a discharge driving roller for discharging the recording material by rotating the recording material, and a pressure contact with the discharge driving roller. The present invention relates to a recording apparatus provided with a paper discharge driven roller that can take a position and a position retracted upward.

[0002]

2. Description of the Related Art There is an ink jet printer (hereinafter abbreviated as "printer") as one of recording apparatuses. The printer has a side view of a recording head for recording on a recording material and a discharge path of the recording material. A discharge main frame made of a plate-like member that extends substantially horizontally from the vicinity of the recording head toward the downstream side, and a state provided on the upper side of the discharge main frame and parallel to the discharge main frame, By rotating the upstream side end portion of the discharge main frame as a rotation fulcrum, the discharge subsidiary made of a plate-like body is configured to be switchable between a state in which the downstream side is lifted from the discharge main frame. A frame, a paper ejection drive roller provided below the paper ejection main frame for ejecting a recording material on which recording has been performed by rotating, and a window hole provided in the paper ejection main frame. The paper is ejected so that it projects downward. Provided on the frame, by the sheet discharge sub-frame is rotated, and the discharge follower roller retracted upward away from the paper discharge driving rollers are provided with a.

The reason why the paper discharge driven roller is retractable upward from the paper discharge drive roller is as follows. That is, when the paper ejection driven roller is a toothed roller, more specifically, it is a toothed roller that has a plurality of teeth around it and is sharply sharpened so that the tips of the teeth make point contact with the printing surface. Then, when the recording material is, for example, a compact disc medium, the teeth come into point contact with the printing face of the compact disc medium to act on the data storage portion immediately below the printing face of the compact disc medium. This is because data may be destroyed in rare cases. Therefore, in order to prevent such a problem, it is possible to switch the discharge driven roller so that it is not pressed against the recording material to be conveyed.

By the way, since the recording material ejects ink droplets from the ink jet recording head, when the recording material is plain paper or the like, it absorbs the ink droplets and wavy in the main scanning direction (cockling phenomenon). ) Occurs.
If such a cockling phenomenon occurs in the vicinity of the inkjet recording head, the recording surface (printing surface) may come into contact with the inkjet recording head, and so-called head rubbing may occur. Therefore, in order to prevent this, it is desirable to provide a regulation roller near the downstream side of the inkjet recording head to regulate the lifting of the recording material.

[0005]

However, as described above, the paper discharge driven roller is moved upward by the paper discharge main frame and the paper discharge subframe that rotates about the upstream end of the paper discharge main frame as a fulcrum. In the retracting configuration, if a regulating roller is provided in the vicinity of the downstream side of the inkjet recording head, that is, on the upstream side of the discharge subframe, and the regulating roller is retracted upward by the rotation of the discharge subframe, the regulation is performed. Since the roller is located in the vicinity of the rotation fulcrum of the paper discharge subframe, the amount of upward withdrawal becomes small, and it becomes impossible to secure a sufficient amount of withdrawal. On the other hand, if the retracting mechanism of the regulation roller is provided separately and independently from the rotating mechanism of the paper discharge subframe, the structure becomes complicated and the cost increases.

Therefore, the present invention has been made in view of such a problem, and its object is to rotate a discharge roller by a regulating roller arranged in the vicinity of a rotation fulcrum of the discharge slave frame. , To evacuate upward with a sufficient amount of evacuation.

[0007]

In order to solve the above-mentioned problems, a recording apparatus according to claim 1 of the present application has a recording head for recording on a recording material and a paper discharge path of the recording material as viewed from the side. A sheet discharge main frame that extends from the vicinity of the downstream side of the recording head to the downstream side, a sheet discharge main frame that is provided above the sheet discharge main frame and is parallel to the sheet discharge main frame, and a state of the sheet discharge main frame. By rotating with the upstream end as the rotation fulcrum,
A paper discharge sub-frame composed of a plate-like member, which is configured to be able to switch between a state in which the downstream side is lifted from the paper discharge main frame, and a lower side of the paper discharge main frame, which is provided by rotating the recording main frame. A discharge driving roller that discharges the recording material that has been performed, and the discharge sub-frame so as to project downward from a window hole provided in the discharge main frame,
A recording apparatus provided with a sheet discharge driven roller which is separated from the sheet discharge drive roller and retracts upward by the rotation of the sheet discharge subframe, and is arranged in the vicinity of the downstream side of the recording head. , A freely rotatable restriction roller, and a holder rotation shaft provided between the restriction roller and the paper discharge driven roller in the paper discharge main frame as a rotation center,
It is rotatably provided by looking at the paper discharge path of the recording material.
A regulation roller holder that pivotally supports the regulation roller, the regulation roller holder protruding above the paper ejection slave frame from a window hole provided in the paper ejection slave frame, and the paper ejection slave frame. A sliding portion that slides on the upper surface of the frame is provided between the holder rotation shaft and the regulation roller, and when the paper ejection slave frame rotates, the sliding portion is lifted by the upper surface of the paper ejection subframe. And the regulation roller holder is rotated by sliding on the upper surface of the sheet discharge subframe, whereby the regulation roller is retracted upward together with the sheet discharge subordinate roller. Characterize.

According to the first aspect of the present invention, the discharge main frame extending downstream from the vicinity of the downstream side of the recording head, and the upstream end of the discharge main frame provided on the upper side of the discharge main frame. In the configuration in which the discharge driven roller is retracted upward by a discharge secondary frame that rotates so that the downstream side floats above the discharge main frame with the rotation fulcrum as a fulcrum,
It is possible to provide a regulating roller in the vicinity of the rotation fulcrum of the paper ejection slave frame, and to rotate the paper ejection slave frame upward with a sufficient retraction amount by rotating the paper ejection slave frame. Become. That is, the regulation roller is near the recording head to prevent the recording material from being rubbed by the head,
That is, since it is provided in the vicinity of the rotation fulcrum of the paper discharge subframe, the amount of retreat to the upper side cannot be gained if the regulating roller is directly provided in the paper discharge subframe.

Therefore, a regulation roller holder that pivotally supports the regulation roller is provided so as to be rotatable around a holder rotation shaft provided between the regulation roller and the paper discharge driven roller. Further, a sliding portion that projects above the discharge subframe and slides on the upper surface of the discharge subframe is provided between the holder rotation shaft and the regulation roller. By doing so, when the paper ejection slave frame rotates, the sliding portion is lifted by the upper surface of the paper ejection slave frame, and by sliding on the upper surface of the paper ejection slave frame, the regulation roller holder rotates. As a result, the regulation roller retracts upward together with the paper discharge driven roller.

That is, while the regulation roller is configured to be retracted upward together with the paper ejection driven roller by the rotation of the paper ejection slave frame, the rotation fulcrum of the regulation roller holder that pivotally supports the regulation roller is the paper ejection slave. Since it is set separately from the rotation fulcrum of the frame, it is possible to increase the amount of retreat of the restriction roller above, as compared with the case where the restriction roller holder is directly provided in the vicinity of the rotation fulcrum of the paper discharge subframe. The regulation roller can be retracted upward with a sufficient amount of retraction, and since the regulation roller is retracted together with the paper ejection driven roller by rotating the paper ejection subframe, the retraction mechanism of only the regulation roller is independent. The structure is simpler and the cost increase can be prevented compared to the structure provided in the above.

According to a second aspect of the present invention, there is provided a recording apparatus according to the first aspect.
In the above, in the upper surface of the paper discharge sub-frame, a portion on which the sliding portion slides has a raised shape.
According to the invention of claim 2 of the present application, since the portion of the upper surface of the sheet discharge sub-frame on which the sliding portion slides has a raised shape, the upper surface of the sheet discharge sub frame is flatter than that of the case. As a result, the amount of rotation of the regulation roller (regulation roller holder) can be increased, so that the regulation roller can be retracted further upward.

The recording apparatus according to claim 3 of the present application is the recording apparatus according to claim 1.
Alternatively, in the second aspect, a cam portion is formed on the holder rotation shaft, and the sheet discharge subframe is rotated by rotating the holder rotation shaft. According to the invention of claim 3 of the present application, a cam portion is formed on the holder rotation shaft, and the paper discharge slave frame is rotated by rotating the holder rotation shaft. , Both the discharge subframe and the regulation roller holder are rotated by the holder rotation shaft, and therefore, the mechanism for rotating the discharge subframe and the regulation roller holder is simplified to reduce the cost. Is possible.

Here, FIG. 1 shows the printer 10.
It is a side sectional view of 0. In FIG. 1, the right side of the drawing is the upstream side (rear side of the printer) of the paper P conveyance path, and the left side of the drawing is the downstream side (front side of the printer).

The printer 100 is provided with a paper feeding device 2 for feeding the paper P upstream. The paper feeding device 2 is provided with a hopper 16 on which the sheets P as cut sheets are accumulated and stored in an inclined posture. The hopper 16 is provided so as to be rotatable around a rotation fulcrum (not shown) located above the rear portion of the sheet feeding device 2, and its tip is pressed against and separated from the sheet feeding roller 14 which is driven to rotate. It is designed to work. And
The hopper 16 presses the paper feed roller 14 under pressure, and the paper feed roller 14 rotates in the pressure contact state, so that the uppermost one of the accumulated paper P is delivered to the downstream side. The paper feed roller 14 has a substantially D-shape when viewed from the side, and is controlled so that the flat portion thereof faces the paper P during the printing operation (the state of FIG. 1).
Reduce the transport load.

A paper guide 15 as a plate-like member is provided substantially horizontally below the paper feed roller 14 and the front end of the paper P fed from the paper feed device 2 obliquely contacts the paper guide 15. It touches and is smoothly guided to the downstream side. A transport driving roller 19a that is rotatably driven downstream from the paper guide 15, a transport driven roller 19b that is in pressure contact with the transport driving roller 19a,
Is provided, and the sheet P is nipped by the conveyance roller 19 and is conveyed at a constant pitch to the downstream side. The transport driven roller 19b is axially supported on the downstream side of the transport driven roller holder 18, and the transport driven roller holder 18 is provided so as to be rotatable about the rotation shaft 18a in the clockwise direction and the counterclockwise direction in FIG. In addition, the transport coil 19b (not shown) is urged to rotate the transport driven roller 19b in the direction in which the transport driven roller 19b is constantly in pressure contact with the transport drive roller 19a (counterclockwise direction in FIG. 1).

The transport driven roller holder 18 can be rotated clockwise in FIG. 1 by a cam 26 which is rotated by an operation lever (not shown) operable by the user. The transport driven roller 19b can be located at a position separated from the transport drive roller 19a.

Next, from the paper feed roller 14 to the transport roller 19
A sheet detector 17 including a sensor body 17a and a detector 17b for detecting the passage of the sheet P is disposed on the sheet P feeding path. The detector 17b has a substantially V shape when viewed from the side, and has a rotating shaft 17c near the center thereof.

Has been done. The sensor main body 17a located above the detector 17b includes a light emitting portion (not shown) and a light receiving portion (not shown) that receives light from the light emitting portion, and the sensor main portion 17a is located above the rotating shaft 17c of the detector 17b. The rotation operation blocks and passes the light traveling from the light emitting section to the light receiving section. Therefore, as shown in FIG. 1, when the detector 17b is rotated so as to be pushed upward with the passage of the paper P, the upper side of the detector 17b is disengaged from the sensor main body 17a, whereby the light receiving portion is in the light receiving state. Therefore, the passage of the paper P is detected.

Subsequently, downstream of the conveying roller 19, a platen 28 and an ink jet recording head 13 which constitute a recording portion of the printer 100 are arranged so as to face each other vertically. The platen 28 is long in the main scanning direction (the front-back direction of the paper surface of FIG. 1), and the paper P conveyed below the inkjet recording head 13 by the conveyance roller 19 is the platen 2.
8 supported from below. The inkjet recording head 13 is provided on the bottom of a carriage 10 on which the ink cartridge 11 is mounted, and the carriage 10 reciprocates in the main scanning direction while being guided by a carriage guide shaft 12 extending in the main scanning direction.

Next, a sheet discharge section of the printer 100 is provided downstream from the ink jet recording head 13, and a sheet discharge drive roller 20a which is rotationally driven and the sheet discharge drive roller 20 are provided.
A paper discharge roller 20 including a paper discharge driven roller 20b that is rotated by being lightly pressed against a is provided, and the paper P printed by the inkjet recording head 13 is nipped by the paper discharge roller 20. The sheet is discharged by rotating the sheet discharge driving roller 20a.

The paper discharge driven roller 20b is a toothed roller having a plurality of teeth on its outer circumference, and the paper discharge driven roller holder 23 is provided.
It is rotatably supported by. The rotation shaft of the paper discharge driven roller 20b is composed of an elastically deformable rod spring (not shown), so that the paper discharge driven roller 20b slightly moves in the direction orthogonal to the axial direction according to the paper thickness of the paper P. It can be displaced.

Next, the paper discharge driven roller holder 23 which pivotally supports the paper discharge driven roller 20b is attached to the paper discharge driven frame 25. The paper discharge sub-frame 25 is formed of a plate-like member that is long in the main scanning direction, and is viewed from the side of the paper discharge path of the paper P in FIG.
As shown in, the ink jet recording head 13 extends substantially horizontally from the vicinity of the downstream side toward the downstream side. The discharge sub-frame 25 is also long in the main scanning direction, and extends substantially horizontally from the vicinity of the downstream side of the inkjet recording head 13 toward the downstream side. It is attached in a state of being pressed against from above by 27.

Here, the paper discharge driven roller 20b is separated from the paper discharge driving roller 20a and retracted upward by the paper discharge driven frame 25 rotating about the upstream end of the paper discharge main frame 24 as a fulcrum. It is possible to do this for the following reasons. That is, the printer 1
In addition to the sheet P as a cut sheet, a print medium 00 is thick and does not easily bend, for example, a compact disc medium (hereinafter abbreviated as CD) can be conveyed and printed. However, since the paper ejection driven roller 20b is a toothed roller as described above, when the teeth make point contact with the printing surface of the CD, they act on the data storage portion immediately below the printing surface of the CD. May destroy data. Therefore, in order to prevent such a problem, when the print medium is a CD, the paper discharge driven roller 20b does not come into pressure contact with the print surface of the CD.
The paper discharge driven roller 20b is retracted upward. At this time,
The sheet discharge auxiliary roller 22 and the regulation roller 29, which will be described later, are also configured to be retracted upward at the same time, which will be described later in detail.

Subsequently, a paper discharge auxiliary roller 22 is provided slightly upstream of the paper discharge driven roller 20b, and the paper P is pressed slightly downward by the paper discharge auxiliary roller 22. Further, the nip point between the paper discharge drive roller 20a and the driven follower roller 20b is set slightly upstream, and further, the transport drive roller 19a and the transport driven roller 19 are set.
The nip point with b is set slightly downstream. As described above, the sheet P is in a curved state in which it is slightly convex downward between the paper discharge roller 20 and the transport roller 19, and the sheet P positioned below the inkjet recording head 13 is in the platen 28.
The paper P is prevented from floating,
Normal print quality is maintained. The paper ejection auxiliary roller 22 is a toothed roller like the paper ejection driven roller 20b described above, has an elastically deformable rotation shaft (bar spring) (not shown), and the paper ejection auxiliary frame 25. It is rotatably supported by a paper discharge auxiliary roller holder 21 attached to the.

Next, a regulating roller 29 is arranged on the upstream side of the discharge assisting roller 22 and in the vicinity of the downstream side of the ink jet recording head 13. The regulation roller 29 is a toothed roller like the paper ejection driven roller 20 b and the paper ejection auxiliary roller 22, and plays a role of restricting the lifting of the paper P in the vicinity of the inkjet recording head 13. That is, the paper P is the inkjet recording head 13
Since ink droplets are ejected from the printer, the phenomenon of waviness in the main scanning direction due to absorption of ink droplets (cockling phenomenon)
However, if such a cockling phenomenon occurs in the vicinity of the inkjet recording head 13, the printing surface may contact the inkjet recording head 13 and so-called head rubbing may occur. Therefore, the regulation roller 29 regulates the lifting of the sheet P to prevent the above-mentioned head rubbing. The mounting structure of the regulation roller 29 will be described later in detail.

The above is the overall configuration of the printer 100.
Next, the paper discharge driven roller 20b and the paper discharge auxiliary roller 22
The retracting means for retracting the regulation roller 29 upward will be described with reference to FIGS. 2 and 3. Here, FIG. 2 is a side sectional view of the paper discharge main frame 24 and the paper discharge subframe 25. FIG. 2A shows a state in which the paper discharge driven roller 20b is in pressure contact with the paper discharge drive roller 20a, and FIG. The state in which the paper driven roller 20b is separated from the paper discharge drive roller 20a is shown. 3A and 3B are enlarged side views of the regulation roller holder 30. FIG. 3A shows a state where the regulation roller 29 projects downward, and FIG. 3B shows a state where the regulation roller 29 retracts upward.

First, in FIG. 2 (A), as described above, the discharge sub-frame 25 is provided in parallel with the discharge main frame 24 so that the coil spring 27 presses the discharge sub-frame 25 from above. On the upstream side of the paper discharge main frame 24, there are two claw portions 24b that are bent vertically downward to form an L-shape in the longitudinal direction of the paper discharge main frame 24 (main scanning direction: front and back direction in FIG. 2) ( (Not shown in detail). Also,
The upstream side of the paper discharge subframe 25 is uniformly bent vertically downward (in the direction indicated by reference numeral 25d) in the longitudinal direction (front and back directions in the drawing) to form an L-shape.
Insertion holes 25e for inserting the claw portions 24b are provided in 5d at two positions in the longitudinal direction of the paper discharge subframe 25 (details not shown).
The claw portion 24b is formed so as to protrude from the insertion hole 25e, and the upper end of the bent portion 25d (reference numeral 25c in FIG. 3).
(Shown with)).

Next, a groove portion 24a extending in the longitudinal direction is formed in the paper discharge main frame 24, and a holder rotating shaft 31 extending in the longitudinal direction is fitted in the groove portion 24a. The holder rotation shaft 31 has a fan-shaped cam portion 3 when viewed in the axial direction.
1a is formed, whereby the holder rotation shaft 31 is formed.
When is rotated, the cam portion 31a pushes up the paper ejection slave frame 25, and the paper ejection slave frame 25 bends the bent portion 25d.
2 is rotated in the clockwise direction in FIG. 2 with the upper end portion of the sheet, that is, the upstream side end portions of the discharge main frame 24 and the discharge subframe 25 as the fulcrum of rotation, and as shown in FIG. The downstream side of 25 is configured to be lifted from the paper discharge main frame 24.

That is, the paper discharge sub-frame 25 can be switched by the holder rotating shaft 31 between a state parallel to the paper discharge main frame 24 and a state in which the downstream side is lifted from the paper discharge main frame 24. The holder rotation shaft 31 can be rotated by an operation lever (not shown) that can be operated by the user. As described above, the paper ejection driven roller 2 provided on the paper ejection subframe 25 is provided.
0b and the discharge assisting roller 22 are changed from the state shown in FIG. 2A to the state shown in FIG. 2B by the rotation of the discharge auxiliary frame 25, and are separated from the discharge driving roller 20b and retracted upward. To do.

Next, in FIG. 3, the regulating roller 29 arranged near the upstream end portions of the discharge main frame 24 and the discharge sub-frame 25 (in the vicinity of the downstream side of the ink jet recording head 13) has a rotating shaft 29a. By being pivotally supported by the regulation roller holder 30, it is possible to freely rotate below the paper discharge main frame 24. The regulation roller holder 30 is rotatable about the holder rotation shaft 31 by a shape such that it holds the holder rotation shaft 31 located between the regulation roller 29 and the paper discharge driven roller 20b. By rotating, it is possible to swing vertically in the window hole 24c formed in the paper discharge main frame 25 and the window hole 25a formed in the paper discharge subframe 25. still,
The regulation roller holder 30 has a direction in which the regulation roller 29 always projects downward by a coil spring (not shown) (see FIG. 3).
It is urged to rotate in the clockwise direction.

In addition, the regulating roller holder 30 is formed with a portion projecting upward from the upper surface of the paper discharge sub-frame 25, and the portion projecting upward projects in the direction of the back of the paper of FIG. The sliding portion 32 is formed, and the window hole 2
It can slide on the edge of 5a (the upper surface of the paper discharge subframe 25) (see also FIG. 2). As described above, when the paper discharge subframe 25 rotates about the upper end of the bent portion 25d (the portion indicated by the reference numeral 25c in FIG. 3) as a fulcrum, the regulation roller holder 30 moves as shown in FIGS. 3A to 3B. The sliding portion 32 is lifted up by the paper ejection slave frame 25, and the sliding portion 32 is moved by the paper ejection slave frame 2.
By sliding on the upper surface of 5, the counter roller rotates in the counterclockwise direction in FIG. 3, and the regulation roller 29 retreats upward. And FIG.
As shown in (B), printing is performed on the thick print medium T (for example, the above-mentioned CD) with the regulation roller 29, the paper ejection driven roller 20b, and the paper ejection auxiliary roller 22 retracted upward. This makes it possible to prevent the print medium T from being adversely affected.

That is, the regulation roller 29 prevents the head P of the paper P from rubbing against the ink jet recording head 13 as described above.
Although it should be disposed in the vicinity of the downstream side of the sheet, the regulation roller 29 is provided with the sheet ejection driven roller 20b or the sheet ejection auxiliary roller 2
As in the case of 2, the position of the regulating roller 29 is close to the rotation fulcrum of the discharge subframe 25 (the portion indicated by the reference numeral 25c) only by providing it on the discharge subframe 29, and the amount of retreat upward cannot be earned. However, the print medium T cannot be reliably protected.
However, the regulation roller 29 is provided on the regulation roller holder 30, and the regulation roller holder 30 is rotated about a rotation fulcrum (holder rotation shaft 31) different from the rotation fulcrum of the paper ejection slave frame 25. With this configuration, the regulation roller 29 can be sufficiently retracted upward.

Incidentally, the holder rotating shaft 31 is used for the paper discharge subframe 2
5 is a rotation shaft for rotating both the regulation roller holder 30 and the regulation roller holder 30. By configuring as described above, the paper ejection driven roller 20b and the paper ejection auxiliary roller 22 are provided on both sides of the holder rotation shaft 31. , And the regulation roller 29 can be rotated.

By the way, the portion where the sliding portion 32 slides is
In the present embodiment, as shown in FIG. 3, it is formed in a raised shape (portion indicated by reference numeral 25b), and the amount of rotation of the regulation roller holder 30 is increased by the raised shape, and the regulation roller 29 is retracted further upward. It is possible to let them do it.

[0034]

As described above, according to the present invention, the regulating roller is axially supported while the regulating roller is retracted upward together with the ejecting driven roller by the rotation of the ejecting driven frame. Since the rotation fulcrum of the regulation roller holder is set separately from the rotation fulcrum of the paper ejection slave frame, the regulation roller holder is set above the regulation roller as compared with the case where the regulation roller holder is directly provided near the rotation fulcrum of the paper ejection slave frame. It is possible to increase the amount of displacement of the regulating roller, and thus the regulating roller can be retracted with a sufficient retracting amount.
