Description of the Related Art Generally, an image recording apparatus having a recording mechanism of an ink jet system, a thermal transfer recording mechanism, or the like performs a recording operation while scanning the recording mechanism relative to a sheet material such as paper. To obtain a two-dimensional image.

[0003] Figure 3 b is one of the image recording apparatus
This is a conventional example of an ink jet recording apparatus . In this configuration, a recording sheet is intermittently fed in a predetermined direction by a conveyance roller mechanism, and an ink jet mechanism as a recording unit is scanned in a direction perpendicular to the direction. The sheet 1 is conveyed in the direction of arrow A by a sheet supply mechanism (not shown), and is guided between the upper guide 11 and the lower guide 12. The upper guide 11 and the lower guide 12 are supported by a bottom plate 102 which forms a part of the apparatus main body.

Further, the sheet 1 enters a joining portion between the sub-scanning roller 13 and the sub-scanning driven roller 14 supported by the bearings 31 and 32. By rotation of both rollers, the sheet 1 becomes the bottom plate 1
02 while being supported by the platen 19 fixed to 02
The sheet enters the joint between the discharge roller 20 and the discharge driven roller 21 supported by 34. The discharge guide 24 is supported by the bottom plate 102, and guides the discharge direction of the recording sheet 1 conveyed in the direction of arrow A to the outside of the apparatus main body by the rotation of the discharge roller 20 and the discharge driven roller 21.

[0005] A left side plate 103 and a right side plate 104 having vertical surfaces are fixed to the left and right sides of the bottom plate 102. The bearing portions 31 and 33 are supported by the left side plate 103, and the bearing portions 32 and 34 are supported by the right side plate 104.
And the right side plate 104. The transport motor 17 for applying a rotational driving force to the sub-scanning roller 13 and the discharge roller 20 is fixed to the left side plate 103 via a motor stopper 26.

A sub-scanning roller 13 is located above the platen 19 at the back.
The main scanning rail 6 arranged in parallel with the axial direction of FIG. The carriage 7 is inserted into the main scanning rail 6 and is movable in the axial direction of the main scanning rail 6 by the main scanning motor 2 fixed above the left side plate 103.

The carriage 7 has ink cartridges (black 8Bk, cyan 8C, magenta 8M, yellow 8Y) having four colors of ink attached at predetermined positions. Each ink cartridge 8 holds an ink jet head in which a plurality of nozzles (not shown) are arranged on the lower side in a direction perpendicular to the direction of movement of the carriage 7. It can be discharged toward the 19 side.

When the carriage 7 is in a standby state before recording at the position indicated by the one-dot chain line on the right side of FIG. 3 , that is, at a so-called home position, a nozzle held by each ink cartridge 8 at the time of image recording is located immediately below the carriage 7. A recovery unit 9 for maintaining the device in a good state and for recovering it to a good state is fixed to a bottom plate 102 constituting the apparatus main body.

[0011]

However, in the conventional ink jet recording apparatus as described above, since parts related to image recording are dispersedly mounted on each part at the bottom of the apparatus main body, each of the members of the conveying means is not provided. It is difficult to obtain high precision in the relative positional relationship, and there is a problem as described below.

(1) Due to poor positional accuracy between the moving force applying member for applying the moving force to the sheet material such as each roller pair and the conveying path guide member or the recording sheet support member, the conveying direction of the recording sheet is limited by its width. It tends to be non-uniform in the direction, and liable to cause transport failures such as skew, corner breaks, and catching.

(2) The non-uniformity in the transport direction during the movement, that is, the non-uniformity of the velocity vector component in the specific direction, makes the transport amount non-uniform. In particular, if the recording sheet has the non-uniformity in the plane above the support member of the recording sheet in the image recording portion, the recording sheet is loosened or stretched,
When an image is recorded there, the image is distorted due to slack or tension, and furthermore, it is impossible to carry out a predetermined amount of accurate conveyance, so that image density unevenness or streaks in the conveyance direction occurs on the image. , Lowering the image quality.

(3) The main part of the image recording portion is ink
Since the parts are concentrated in the lower part of the main body of the jet recording apparatus and relatively inside, the assembling workability is very poor when assembling the parts.

(4) If the recording sheet has a conveyance failure near the image recording portion, the recording sheet is located at the lower part of the main body of the recording apparatus and relatively inside, so that the recording sheet can be easily removed. Absent.

The present invention relates to recording of an ink jet recording apparatus.
The main members involved in sheet conveyance are configured to be able to be positioned accurately with respect to each other, stabilizing the conveyance of the recording sheet and improving the image quality of the recorded image, and at the same time, improving the assemblability and conveyance of the members. An object of the present invention is to improve the processability of a defective recording sheet.

Since it is supported by the same base 25 as the bearing portion 31, the positional relationship between the two can be accurately defined. Discharge guide
24 is a means for guiding into the housing outside of the apparatus body 101 to the recording sheet 1 is conveyed by the discharge roller 20 and follower roller 21.

A sub-scanning pulley 15 is fixed to a left end of the sub-scanning roller 13 in FIG. 1, and a discharge pulley 22 is fixed to a left-side end of the discharge roller 20 in FIG. On the other hand, the transport motor 17 is fixed to the base 25 via a motor stopper 26 at the lower left portion of the base 25. A transport motor pulley 17 is fixed to a rotation shaft of the transport motor 17, and transmits a rotational driving force to the sub-scanning pulley 15 and the discharge pulley 22 via the sub-scanning belt 16 and the discharge belt 23. At this time, the diameter of the discharge pulley 22 depends on the conveying speed of the discharge roller 20 and the sub-scanning roller 13.
Is set to be slightly faster than the transfer speed of the above.
Further, the gripping force on the sub-scanning roller 13 side with respect to the recording sheet 1 is set to be stronger than the gripping force on the discharge roller 20 side. The recording sheet 1 does not slack on the platen 19.

On the upper left side of the platen 19, the sub-scan roller 13
The main scanning rail 6 arranged in parallel with the axial direction of the
Fixed to 101. The carriage 7 has a bearing 7
The main scanning rail 6 is inserted through A, and can be moved in the axial direction of the main scanning rail 6 (the directions of arrows B and C in FIG. 1). The main scanning motor 2 is disposed above the left side of the main scanning rail 6 and is fixed to a side plate of the apparatus main body 101. A main scanning motor pulley 3 is fixed to a rotating shaft of the main scanning motor 2, and can rotate integrally with the rotating shaft. Idler pulley 5
Is a position facing the main scanning motor pulley 3 in the direction of arrow B in FIG. 1 and is rotatably supported by a side plate of the apparatus main body 101.

The main scanning belt 4 is a main scanning motor pulley 3
Between the main scanning motor 2 and the idler pulley 5
Is driven with the rotation of. The main scanning belt 4 and the carriage 7 are connected between the pulleys 3 and 5, and the carriage 7 is driven in the arrow B direction or the arrow C direction by rotation of the main scanning motor 2. A roller 7B rotatably supported is disposed below the carriage 7 (see FIG. 2), and rolls on the recording sheet 1 supported by a platen shaft to thereby provide a space between the carriage 7 and the recording sheet 1 in the height direction. Is defined.

The carriage 7 has four ink cartridges 8 each having different color inks fixed at predetermined positions. These are a black ink cartridge 8Bk, a cyan ink cartridge 8C, a magenta ink cartridge 8M, and a yellow ink cartridge 8Y. Platen at the bottom of each ink cartridge 8
An ink jet head 8A composed of a plurality of nozzles arranged in a direction perpendicular to the moving direction of the carriage 7 and a mechanism for applying an ink ejection force to the nozzles is provided at a position opposed to 19 as shown in FIG. keeping. Each of the inkjet heads 8A can eject ink dots from the ink in the ink cartridge toward the recording sheet 1 supported on the platen 19. The inkjet head 8A has various types of energy for ejecting ink. In this embodiment, the inkjet head 8A is provided with a means for generating thermal energy (for example, an electrothermal converter or a laser beam), and the thermal energy causes a change in the state of the ink. We use what causes it. According to this method, the recording density is increased,
This is because high definition can be achieved.

When the carriage 7 and the ink cartridges 8Y, 8M, 8C, 8Bk, etc. loaded thereon do not perform the image recording operation, the carriage 7 is controlled by the drive of the main scanning motor 2 so that the ink cartridges 8Y, 8M ,
It is possible to move together with 8C and 8Bk to the position shown by the solid line in FIG. 1 which is outside the recording area. When the carriage 7 is at the above position, in order to prevent clogging due to drying inside each nozzle, a cap for sealing the nozzle of each ink jet head 8A so as to keep the inside of the nozzle wet. Caps 10Y, 10M, 10C and 10Bk are used as base material.
Is placed on top.

A recovery unit 9 is disposed on the base 25 behind the caps 10Y, 10M, 10C, and 10Bk to perform a recovery process for recovering more than the ejection of ink due to unnecessary bubbles or impurities generated inside each nozzle. Have been. Inside the recovery unit 9, there is a built-in suction pump that reduces the pressure inside each cap 10Y, 10M, 10C, 10Bk, sucks unnecessary bubbles and impurities inside each nozzle together with ink, and removes them from inside the nozzle. doing. The suction pump has a mechanism for converting the rotational driving force into a negative pressure, and obtains the rotational driving force of the sub-scanning roller 13 through the gears 41 and 42 to obtain the driving force of the pump.

In the present embodiment, the transport rollers, the transport motor, and the like are configured to be displaceable by a displacement means to a position where they can be attached to and detached from the apparatus main body. On the discharge side of the device body 101, a base support that can expand and contract on both the left and right sides when viewed from the discharge side
Each end of a slide rail 35 as a means and a slide rail 36 is attached. Meanwhile, slide rail 35
The other end of the slide rail has engagement holes 43 and 44, and the other end of the slide rail 36 has an engagement hole (not shown) at a position symmetrical to the engagement holes 43 and 44.
There are 45 and 46. These engagement holes are located in the lower part on both sides of the base 25.
Engagement pins 47 and 48 which engage with 43, 44, 45 and 46 and engagement pins 49 and 50 (not shown) are fixed. This allows the base 25 to be moved by a plurality of slide rails 35 and 36 together with the slide operation .
The rollers are used to
Guide the recording sheet to the position that is separated and opposed at intervals and records
The recording position where ink jet recording can be performed on the sheet
Remove the base from the inkjet recording device outside the body
It can be moved to a detachable position where it can be removed .

The upper guide 11, the lower guide 12, the discharge guide 24,
Bearings (31, 32, 33, 34), platen 19, transport motor 1
7. The base 25 to which the recovery unit 9 and the like are fixed is supported by these two slide rails 35 and 36,
With 37 it is possible to withdraw in the discharge direction. After being pulled out, the base 25 can be removed from the slide rail by removing the engagement between the engagement pins 47, 48 and the engagement pins 49, 50 (not shown) from the engagement holes 43, 44, 45, 46. .

The recording operation is as follows. The recording sheet 1 is transported in the direction of arrow A by a sheet transport mechanism (not shown), and is inserted between the upper guide 11 and the lower guide 12 fixed to the base 25. Further, the recording sheet 1 is guided in the traveling direction by the two guides 11 and 12, and enters the joining portion between the sub-scanning roller 13 and the sub-scanning driven roller 14. Both guides 11, 12
The positional relationship between the recording sheet 1 and the sub-scanning roller 13 and the sub-scanning driven roller 14 is precisely defined, so that the recording sheet 1 reaches the joining portion accurately. When the transport motor 17 is driven and controlled, the sub-scanning roller 13 and the sub-scanning driven roller 14 rotate, the recording sheet 1 is carried out onto the platen 19, and further reaches the joining portion of the discharge roller 20 and the discharge driven roller 21. Here, the transport roller temporarily stops.

The height of the joint between the sub-scanning roller 13 and the sub-scanning driven roller 14, the upper surface of the platen 19, and the junction between the discharge roller 20 and the discharge driven roller 21 are precisely defined. Since the parallelism between the joint on the side of the roller 13 and the joint on the side of the discharge roller 20 is also precisely defined, the recording sheet 1 performs an accurate conveyance by obtaining a uniform conveyance direction and conveyance speed in the width direction. I can do it. Therefore, the recording sheet 1 does not slack on the platen 19, and a conveyance failure hardly occurs.

Next, when the main scanning motor 3 is driven and controlled, the carriage 7 starts to move in the direction of arrow C in FIG. 1. During this movement, an ink discharge signal corresponding to the image is output from the main body control unit. Each cartridge 8Y, 8M, 8C,
8Bk is supplied to the inkjet head 8A and the platen
Ink is ejected onto the recording sheet 1 on the top 19 to form an image having a predetermined width. Thereafter, the main scanning motor 2 is driven to rotate in the reverse direction, and the carriage 7 moves in the direction of arrow B and reaches outside the image forming area. Thereafter, the intermittent feeding of the recording sheet 1 is repeated, and each time, the scanning drive of the carriage 7 and the ink ejection operation of each ink jet head 8A are repeated to obtain a two-dimensional image.

In order to assemble the main members in the recording portion related to the conveyance of the recording sheet 1, after assembling on the base 25 in advance, the base 25 is pushed and slid with the handle 37, and
The rear surface of the base 25 may be positioned by abutting against the stop plates 27 and 28.
It has been maintained above. If the recording sheet 1 has a conveyance failure near the image recording area, if the base 25 is pulled out with the handle 37, the conveyance failure sheet can be pulled out together, so that the processing can be easily performed.

In this embodiment, since the transport motor 17 and the drive transmission system are integrally formed with the sub-scanning roller 13 and the discharge roller 20, there is no change in tension due to the attachment and detachment of the sub-scanning belt 16 and the discharge belt 23. The driving response is stabilized. Therefore,
The transfer amount is constant, and the image quality is improved.

[Other Embodiments] In the above-described embodiment, the ink jet recording system is used as the recording means. However, an electric current is supplied to the electrothermal converter according to a recording signal, and the heating is performed by the electrothermal converter by heating exceeding nucleate boiling. It is further preferable that the recording is performed by discharging the ink from the discharge port by the growth of the generated bubble.

Regarding the typical configuration and principle, it is preferable to use the basic principle disclosed in, for example, US Pat. Nos. 4,723,129 and 4,740,796. This method can be applied to both the so-called on-demand type and the continuous type. In particular, in the case of the on-demand type, the system is arranged corresponding to a sheet or a liquid path holding a liquid (ink). By applying at least one drive signal corresponding to the recorded information and providing a rapid temperature rise above nucleate boiling to
This is effective because heat energy is generated in the electrothermal transducer, causing film boiling on the heat-acting surface of the recording head, and as a result, bubbles in the liquid corresponding to this drive signal one-to-one can be formed. The liquid is ejected through the ejection opening by the growth and contraction of the bubble to form at least one droplet. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are immediately and appropriately performed, so that particularly excellent liquid ejection can be achieved, which is more preferable.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable.

Further, if the conditions described in US Pat. No. 4,313,124 of the invention relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angled liquid flow path) as disclosed in the above-mentioned respective specifications, The present invention also includes a configuration using U.S. Pat. Nos. 4,558,333 and 4,459,600 which disclose a configuration in which a heat acting portion is arranged in a bending region.

Japanese Unexamined Patent Application Publication No. 59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal transducer for a plurality of electrothermal transducers, or an aperture for absorbing pressure waves of thermal energy. Unexamined Japanese Patent Application Publication No.
The effect of the present invention is effective even in a configuration based on JP-A-59-138461. That is, according to the present invention, the recording can be performed reliably and efficiently regardless of the form of the recording head.

Further, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of a recording medium on which a recording apparatus can record.

Such a recording head may have a configuration satisfying its length by a combination of a plurality of recording heads, or a configuration as a single recording head integrally formed.

In addition, even in the case of the serial type described above, the recording head fixed to the carriage or mounted on the carriage enables electrical connection with the apparatus main body and supply of ink from the apparatus main body. A replaceable chip type recording head or a cartridge type recording head in which an ink tank is provided integrally with the recording head itself may be used.

Further, in addition to the above-described capping means, a cleaning means, a pressurizing or suctioning means, an electrothermal conversion type, or another means other than the capping means, provided as a structure of the ink jet recording apparatus of the present invention. Preheating means by a heating element or a combination thereof,
Performing a preliminary ejection mode in which ejection is performed separately from printing is also effective for performing stable printing.

Regarding the type and number of recording heads mounted on the carriage, for example, instead of providing a plurality of recording heads as in the above-described embodiment, only one recording head may be provided for a single color ink. That is, the recording mode of the recording apparatus may be configured only for the mainstream color such as black, not for color recording.

In addition, in the above-described embodiment, the ink is described as a liquid. However, an ink which solidifies at room temperature or below and which softens or liquefies at room temperature, or an ink jet recording system 30 ink itself
It is common to control the temperature so that the viscosity of the ink is in the stable ejection range by adjusting the temperature within the range of not less than 70 ° C and not more than 70 ° C if the ink is in a liquid state when the use recording signal is applied. good. In addition, positively prevent the temperature rise due to thermal energy by using it as energy for changing the state of the ink from a solid state to a liquid state, or use an ink that solidifies in a standing state to prevent evaporation of the ink. In any case, the ink is liquefied by the application of the heat energy according to the recording signal, and the ink is liquefied, and the liquid ink is discharged. The present invention is also applicable to a case where an ink that liquefies for the first time by energy is used.

The ink in such a case is disclosed in JP-A-54-5
No. 6847 or Japanese Patent Application Laid-Open No. Sho 60-71260, in which the porous sheet is opposed to the electrothermal converter in a state of being held as a liquid or solid substance in the concave portion or through hole of the porous sheet. It is good. The most effective one for each of the above-mentioned inks is to execute the above-described film boiling method.

Further, as the form of the ink jet recording apparatus described above, in addition to those used as image output terminals of information processing equipment such as computers, copying apparatuses combined with readers and the like, and facsimile apparatuses having a transmission / reception function can be used. It may take a form.
