Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device such as a word processor and a printer, and more particularly to a recording device which holds a recording medium after recording on a moving member and then discharges it onto a discharge stacking member.

[0002]

2. Description of the Related Art In recent years, in recording devices such as word processors and printers, a recording medium is intermittently conveyed in a predetermined direction, and a carriage having an ink jet recording head as a recording means is scanned in a direction perpendicular to the recording medium conveying direction. A serial-type recording apparatus for performing recording has been developed and put into practical use.

In the above ink jet recording apparatus,
There is no problem in the case of normal recording, for example, the recording density of standard documents or tables, but in the case of high recording density such as color recording, coated paper is used to efficiently dry the recording paper. It was An apparatus has also been proposed in which a recording apparatus is provided with a drying mechanism to dry recording paper after recording.

Alternatively, in consideration of the manufacturing cost and running cost of the apparatus, there has been proposed a structure which does not rub the recording sheets discharged after recording without providing a drying mechanism. For example, both ends outside the recording area of the recording medium after recording may be held by rails, and when recording is completed, the intervals of the rails may be widened and the recording medium may be stocked in the discharge tray.

[0005]

However, in the structure shown in the above-mentioned prior art, when coated paper or plain paper is used as the recording paper, the recording paper stocked after recording is rubbed with each other unless some drying mechanism is provided. Occurs. Further, when the drying mechanism is provided, the manufacturing cost and the power consumption increase, which may increase the running cost.

In the method of holding both ends of the recording medium after recording outside the recording area by rails, when a wide recording paper, for example, A3 size (294 × 420 mm) recording paper is held by rails in the longitudinal direction, When a recording paper having a weak stiffness (stiffness) is used, there are the following problems under the environment of high temperature and high humidity (the stiffness of the paper becomes weak).

In other words, since the rigidity of the recording paper is low, the central portion is slack, and the recording surface is rubbed against the recording paper already loaded on the discharge tray, or both ends of the recording paper are not conveyed along the rails. was there. In particular, when an image having a high recording density such as color recording is recorded, or when a recording paper in which the ink dries slowly is used, the adverse effect caused by the friction between the recording papers is great. Further, when holding both ends of the recording paper on the rails, it is necessary to move the left and right rails to match the paper size with respect to the recording papers of different sizes, which may be mechanically complicated and costly. there were.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to obtain a good image while maintaining the image quality even when a recording medium having a low rigidity or a recording medium having a different width size is used. To provide a device.

[0009]

A typical means according to the present invention for solving the above-mentioned problems is a feeding means for feeding a recording medium, and an image on the recording medium according to image information. Recording means for recording, ejecting means for ejecting the recording medium after recording, moving member movable in the ejecting direction of the recording medium for supporting the recording medium ejected by the ejecting means, And a discharge stacking member for stacking the recording medium discharged and supported on the moving member.

[0010]

According to the above-described means, the recording medium after recording is conveyed by the discharging means, stocked and held on the moving member for a predetermined time, and when the recording is completed, the moving member is moved to the standby position. The recording medium is discharged onto the discharge stacking member.

[0011]

EXAMPLES Next, the case where the above means is applied to an ink jet printer adopting a serial type ink jet recording system will be described with reference to the drawings. FIG. 1 is a perspective explanatory view showing an external configuration of an inkjet printer, FIG. 2 is a sectional view showing a schematic configuration of the inkjet printer, FIG. 3 is an explanatory diagram showing a configuration of a moving member according to the first embodiment, and FIG. 4 is a recording sheet. 5 is a flowchart for determining the time to stock on the moving member of FIG.

First, a schematic structure of an ink jet printer to which the present invention is applied will be described with reference to FIGS. 1 and 2. The ink jet printer in this embodiment is shown in FIG.
As shown in FIG.
The recording sheet 3 as a recording medium is fed to perform recording.

In FIG. 1, 4 is an operation panel for setting the number of recordings, recording density, etc., 5 is a cover for protecting the recording means, and 6 is a discharge tray which is a discharge stacking member for discharging recording sheets after recording. Is. 7 is the discharge tray 6
It is a stacker lever which is a moving member for holding the recording sheet 3 prior to discharging the recording sheet 3.

As shown in FIG. 2, the recording sheets 3 accommodated in the cassette 2 are fed one by one from the uppermost surface by a feeding roller 8 having a D-shaped cross section which is a feeding means. The recording sheet 3 is guided by the guide members 9 provided above and below the friction roller 10a and the driven roller.
It is conveyed onto the platen 11 by the cooperation of 10b.

Recording is performed by a recording head 12 which is recording means provided so as to face the platen 11. The recording head 12 is mounted on a carriage 13 and records an image according to image information while scanning the carriage 13 along a guide rail 13a in a direction perpendicular to the drawing.

As the recording means, an ink jet recording method is used in which ink is recorded by ejecting ink from the recording head 12. Also, the ink component used contains 50% water.
Ink containing ~ 90% is used. That is, the recording head 12 has a fine liquid discharge port (orifice), a liquid passage and an energy acting portion provided in a part of the liquid passage, and energy for generating a droplet forming energy that acts on the liquid in the acting portion. Equipped with generating means.

As an energy generating means for generating such energy, a recording method using an electromechanical transducer such as a piezo element, electromagnetic waves such as laser are irradiated to generate heat, and droplets are ejected by the action of the heat generation. There are a recording method using an energy generating means, a recording method using an energy generating means for heating a liquid and discharging the liquid by an electrothermal converter such as a heating element having a heating resistor.

Among them, a recording head used in an ink jet recording method for ejecting a liquid by thermal energy has a high density of liquid ejection ports (orifices) for ejecting recording liquid droplets to form ejection liquid droplets. Since they can be arranged, high resolution recording is possible. Among them, the recording head using the electrothermal converter as the energy generating means can easily be made compact, and has the advantages of the IC technology and the microfabrication technology, which have been remarkably improved in the technology and the reliability in the recent semiconductor field. This is advantageous because it can be used in two parts, high-density mounting is easy, and the manufacturing cost is low.

The recording sheet 3 after the image recording is the platen 11
A discharge roller 14a that is conveyed to the downstream side and is discharge means.
It is held on the stacker lever 7 by the spur 14b, and when recording is completed, the stacker lever 7 is moved to a standby position described later and discharged onto the discharge tray 6.

In this embodiment, the ink jet recording system is used as the recording means, but the electrothermal converter is energized in response to a recording signal, and the film boiling caused in the ink is caused by the thermal energy applied by the electrothermal converter. It is more preferable that the recording is performed by ejecting the ink from the ejection port due to the growth and contraction of bubbles generated in the ink.

With regard to its typical structure and principle, it is preferable to use the basic principle disclosed in, for example, US Pat. Nos. 4,723,129 and 4740796. This method can be applied to both the so-called on-demand type and continuous type, but in the case of the on-demand type in particular, it is arranged corresponding to the sheet or liquid path holding the liquid (ink). By applying at least one drive signal to the electrothermal transducer, which corresponds to the recorded information and provides a rapid temperature rise beyond nucleate boiling,
This is effective because heat energy is generated in the electrothermal converter to cause film boiling on the heat acting surface of the recording head, and as a result bubbles in the liquid can be formed in a one-to-one correspondence with this drive signal. Due to the growth and contraction of the bubbles, the liquid is ejected through the ejection opening to form at least one droplet. It is more preferable to make this drive signal into a pulse shape because bubbles can be grown and contracted immediately and appropriately, so that particularly excellent liquid ejection can be achieved.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. If the conditions described in US Pat. No. 4,313,124 of the invention relating to the rate of temperature rise of the heat acting surface are adopted, more excellent recording can be performed.

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

Further, JP-A-59-123670, which discloses a structure in which a common slit is used as a discharge portion of a plurality of electrothermal converters, and an opening for absorbing a pressure wave of thermal energy are disclosed. Japanese Patent Application Laid-Open No. Sho-A-Ko
The effect of the present invention is effective even if the configuration is based on Japanese Patent Publication No. 59-138461. That is, according to the present invention, recording can be reliably and efficiently performed 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 which 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 one recording head integrally formed.

In addition, even in the case of the serial type described above, it is possible to electrically connect to the apparatus main body and supply ink from the apparatus main body by mounting the recording head fixed to the carriage or the carriage. A replaceable chip type recording head or a cartridge type recording head in which an ink tank is integrally provided in the recording head itself may be used.

Further, it is preferable to add recovery means for the recording head, preliminary auxiliary means, etc., which are provided as a configuration of the recording apparatus of the present invention, because the effects of the present invention can be further stabilized. Specific examples thereof include a capping unit for the recording head, a cleaning unit, a pressurizing or suction unit, an electrothermal conversion type or a heating element other than this, or a preheating unit using a combination thereof,
It is also effective to perform stable recording by performing a preliminary ejection mode in which ejection is performed separately from recording.

Regarding the type or number of recording heads mounted on the carriage, for example, only one 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 recording mode of the recording apparatus is not limited to a recording mode of only the mainstream color such as black, but may be a combination of a plurality of recording heads integrally formed, but a mixed color of different colors or a mixed color It is also applicable to a device having at least one of the full colors according to

In addition, although the ink is explained as a liquid in the above-mentioned embodiments, it is an ink which is solidified at room temperature or lower and softens or liquefies at room temperature, or in the ink jet recording system. 30 inks
It is common to adjust the temperature within the range of ℃ to 70 ℃ to control the viscosity of the ink so that it is in the stable ejection range. good. In addition, it is possible to prevent the temperature rise due to thermal energy from being positively used as the energy for changing the state of the ink from a solid state to a liquid state, or to use ink that solidifies when left standing for the purpose of preventing ink evaporation. However, in any case, when heat ink is liquefied by application of heat energy according to a recording signal and liquid ink is ejected, or when the ink reaches a recording sheet, it begins to solidify. It is also applicable when using an ink that has the property of being liquefied for the first time by energy.

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

Further, as the form of the above-mentioned ink jet recording apparatus, besides the one used as an image output terminal of information processing equipment such as a computer, a copying apparatus combined with a reader or the like, and further a facsimile apparatus having a transmission / reception function. It may be a form or the like.

Although an example of using the ink jet recording system as the recording means has been described above, the present invention is not limited to the ink jet recording system, and other thermal transfer recording system, thermal recording system, and Can also be applied to a recording method other than the impact recording method such as the wire dot recording method. Further, it is not necessary to limit to the serial recording method, and a so-called line recording method may be used.

[First Embodiment] Next, the structure of the stacker lever 7 will be described with reference to FIG. The stacker lever 7 is composed of a pair of left and right levers 7a and 7b, and is attached rotatably in the direction of the arrow around the support shafts 15a and 15d provided in the apparatus body 1. A part of the peripheral surface of the support shafts 15a and 15b is provided with a gear portion over a predetermined length.
15c and 15d are formed respectively.

Reference numeral 16 is a drive motor for rotating the stacker lever 7. By rotating the drive motor 16 in the forward and reverse directions, the rotation directions of the levers 7a and 7b are switched. Transmission gears 18 and 19 are in mesh with a motor gear 17 attached to the drive motor 16. The transmission gear 18 is connected to the support shaft 15 via the transmission gear 20.
It meshes with the gear part 15c of a. The transmission gear 19 is a gear portion of the support shaft 15b via transmission gears 21 and 22 meshing with each other.
It meshes with 15d.

Before the start of recording, the levers 7a and 7b are
It stands by so as to overlap the standby position shown by the solid line in FIG. When recording is started, the drive motor 16 is rotated in the clockwise direction (the direction of the solid line arrow in FIG. 3), and the motor gear 17 is rotationally driven in the same direction. At this time, the driving force is transmitted from the motor gear 17 to the support shaft 15c through the transmission gear 18 and the transmission gear 20, and the lever 7a is rotated counterclockwise to be set at the position shown by the chain line in the figure. It on the other hand,
The driving force is transmitted from the motor gear 17 to the support shaft 15d through the transmission gear 19 and the transmission gears 21 and 22, and the lever 7b is rotated clockwise and set to the position shown by the chain line in the figure. The levers 7a and 7b are preferably set at the timing when the recording sheet 3 is fed or when the recording conveyance operation is performed.

When the recording is completed, the drive motor 16 is rotated in the counterclockwise direction (the direction of the broken arrow in FIG. 3), and the motor gear 17 is rotationally driven in the same direction. At this time, the driving force is transmitted from the motor gear 17 to the support shaft 15c via the transmission gear 18 and the transmission gear 20, and the lever 7a is rotated clockwise and returned to the standby position shown by the solid line in the figure. On the other hand, the driving force is transmitted from the motor gear 17 to the support shaft 15d through the transmission gear 19 and the transmission gears 21 and 22, and the lever 7b is rotated clockwise and returned to the standby position shown by the solid line in the figure. ..

Here, a method of determining the stock time T of the recording sheet 3 after the recording is finished will be described with reference to the flowchart shown in FIG. First, in step S1,
The initial value of the stock time T is set to 0 seconds. The initial value of T may be set to a value larger than 0. Next, the process proceeds to steps S2 to S3 to determine the type of recording sheet 3. The type of the recording sheet 3 may be set by the user on the operation panel 4, but it is also possible to identify the recording sheet 3 on the apparatus body side by providing the cassette 2 with a mechanism for selecting the recording sheet 3. If the recording sheet 3 is coated paper, the process proceeds to step S4 and the time T obtained by adding t ₁ to T
Let + t ₁ be the stock time. If the recording sheet 3 is an OHP sheet, the process proceeds to step S5 and t _{2 is set} to T _2.
The time T + t ₂ obtained by adding is the stock time. Incidentally, it is assumed that there is a relationship of t ₂ > t ₁ between the above t ₁ and t ₂ .

Next, in step S6, the type of ink used for recording is identified. In order to identify the type of ink, a known technique for identifying the ink cartridge, for example, electrically identifying a resistance element or the like is used. If the ink at this time is a quick-drying type, the time T + t ₃ obtained by adding t ₃ to T proceeds to step S7 and the stock time.

Next, in step S8, it is determined whether the recording mode is the HQ mode (high quality mode) or another recording mode such as the thinning mode, and H
In the Q mode, the time T + t ₅ obtained by adding t ₅ to T after step S9 is set as the stock time. In the other recording mode, the time T + t ₄ obtained by adding t ₄ to T in step S10 is set. Is the stock time.

Next, in step S11, the total number of dots used for recording one page is counted by the dot counter provided in the apparatus body 1. If this value is larger than the preset number of dots n, step S12 To T to t ₆
The time T + t ₆ obtained by adding is the stock time. Alternatively, the stock time may be added to T by multiplying the total number of dots by a preset constant a. Between the values of the t ₃ ~t _6, and _{t 6> t 5> t 4} > that there is a relation of t _3.

In this embodiment, the time for stocking the recording sheet 3 on the stacker lever 7 is changed according to the recording density. However, the temperature of the recording head 12 increases as the ink ejection amount increases, so recording It is also possible to detect the temperature of the head 12 and lengthen the stock time if the temperature of the recording head 12 is high.

Further, since the ink dries quickly when the temperature of the outside air is high, it is possible to determine the stock time in consideration of the ambient temperature by providing the ambient temperature detection means in the apparatus main body 1. is there.

According to the above construction, even when a recording paper having low rigidity is used as the recording sheet 3, the central portion of the recording sheet 3 immediately after recording is held by the stacker lever 7, so that the ink drying time is secured. Therefore, it is possible to prevent the recording sheet 3 already discharged to the discharge tray 6 from being rubbed and causing stains. Further, it is possible to deal with the small-sized recording sheet 3 by holding the central portion.

Further, an ink containing water is applied to the recording sheet 3
When recording is performed by discharging the ink, the ink has a component that evaporates on the surface of the paper and a component that penetrates into the paper. At this time, most of the components that permeate the paper are water, and the water mainly swells the wood fibers constituting the paper, and the recording paper immediately after recording is curved so that the recording surface side becomes convex. When the water that has penetrated the paper evaporates, the swollen wood fibers contract,
It is curved so that the recording surface side is concave. Therefore, by holding the central portion of the recording sheet 3 by the stacker lever 7, it is possible to reduce the curl that occurs during ink fixing.

Further, depending on the recording density, the stacker lever 7
By changing the time for stocking the recording sheet 3 after recording on top, the ink drying time can be sufficiently secured, and the recording sheet 3 immediately after recording rubs against the already discharged recording sheet 3 and the recording surface becomes It can be prevented from becoming dirty.

Also, the arm 29 can be moved upright and the lateral levers 24, 25 can be moved in parallel with the discharge direction of the recording sheet 3 for setting. The lateral levers 24 and 25 can be smoothly moved in parallel by the pins 29b and 30b protruding from the arms 29 and 30 moving along the elongated holes 24a and 25a, respectively. Further, when returning the lateral levers 24 and 25 to the standby position, the racks and gears can be rotated in the opposite direction and folded to the standby position by activating a drive motor (not shown) in the reverse direction. The method of determining the stock time of the recording sheet 3 on the stacker lever 23 is the first.
It is similar to the embodiment.

[Third Embodiment] Next, a third embodiment of the moving member will be described with reference to FIGS. In this embodiment, the stacker lever 35 is configured by using an elastic body that can expand and contract. In FIG. 6, a stacker lever 35 is provided on the upper surface of the apparatus main body 1 at the discharge port of the recording sheet 3 in parallel with the discharge tray 6 and capable of expanding and contracting in the arrow direction.

It is configured such that one of them is provided at a location and one of them is selectively used. In FIG. 11, stacker levers 35 that can extend and contract in the direction of the arrow are provided at four positions in the width direction in parallel with the discharge tray 6 at the discharge port of the recording sheet 3 provided on the upper surface of the apparatus main body 1. Since the structure of the stacker lever 35 is the same as that of the third embodiment, its explanation is omitted.

Of the levers 35a to 35d, the lever 35 will be described below.
When all a to 35d are used, lever A, lever 35a,
A method of determining the stock time T of the recording sheet 3 is defined by setting the lever B when 35d is used, the lever C when using the levers 35b and 35c, and the lever D when none of the levers 35a to 35d is used. Stacker lever 35
The usage state of will be described with reference to the flowchart shown in FIG.

First, in step S21, the initial value of the stock time T is set to 0 second. The initial value of T may be set to a value larger than 0. Then the recording mode proceeds to step S22 to determine whether the color recording or other monochromatic recording such as migration to the time obtained by adding the t ₁ T + t ₁ the stock time T in step S23 in the case of color recording And

Next, in step S24, it is determined whether or not the image information is a character-only recording. If the image information is character-only recording, the operation proceeds to step S25 and the recording mode is HS.
It is determined whether or not the mode (high speed mode or thinning mode), and if it is the HS mode, the process proceeds to step S26 and the recording sheet after recording in the state of the lever D in which none of the levers 35a to 35d is used. 3 is discharged directly to the discharge tray 6.

[0057] In the above step S25, if the recording mode is other than HS mode, the time obtained by adding the t ₂ T + t ₂ as a stock time T the procedure proceeds to step S27~ step S28, all the levers 35a~35d Is pulled out, and the recording sheet 3 after recording is discharged in the state of the lever A.

If the image information includes not only characters but also graphs and image data in step S24, the process proceeds to step S29 and the recording mode is set to H.
It is determined whether the S-mode, the step S30~ step S31 time obtained by adding t ₃ to T proceeds to T + t ₃ as stock time when a HS mode, the lever 35

If the recording mode is other than the HS mode in step S29, that is, the HQ mode,
Step S32~ step S33 time plus t ₄ to T proceeds to T + t ₄ as stock time, the lever 35b,
Only 35c is pulled out, and in the state of lever C, the recording sheet 3 after recording is ejected while supporting the central portion thereof.

According to the above configuration, the recording form, the image information,
Further, by changing the time T for stocking on the stacker lever 35 of the recording sheet 3 immediately after recording according to the recording mode or the like, it is possible to perform recording while maintaining high image quality without recording stains.

The levers 35a to 35d can be effectively reduced in curl by selectively using each lever according to the curl state of the recording sheet 3. For example, when it is easy to curl upward after recording, only the levers 35a and 35d are pulled out, and the recording sheet 3 after recording is ejected while supporting both sides of the recording sheet in the state of lever B.
If it is easy to curl upward after recording,
It is also possible to eject only 35c while supporting the central portion of the recording sheet 3 after recording with the lever C in the state of the lever C.

Further, the higher the recording density, the more easily the recording sheet 3 curls. Therefore, the higher the recording density, the curl can be reduced by stocking the recording sheet 3 on the stacker lever 35 for a long time.

In the first to fourth embodiments, the recording sheets after recording are provided by equipping the levers 7a and 7b, the lateral levers 24 and 25, and the lever 35a with a heating and drying means such as a planar heater. It is possible to speed up the drying of 3.
