Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that records on a recording medium, and particularly relates to a recording device in which a recording means moves back and forth.

Today, with the development of information processing systems, various recording devices have been developed. One recording method used in such a recording apparatus is a serial type recording apparatus that performs recording while moving a recording head.

For example, in the case of inkjet recording, the recording method is as shown in FIG. It is constructed so that it can transmit the driving force of .

During recording, the motor 54 is driven forward and backward to cause the carriage 51 to travel back and forth in parallel with the platen 55, and in synchronization with this, ink is selectively ejected from the recording head 50 to record on the recording sheet 56. It is.

In the inkjet recording, it is necessary to always maintain a constant distance between the orifice surface of the recording head 50 and the recording sheet 56. For this reason, conventionally, as shown in FIG.
I try not to let it float away. Furthermore, carriage 5
1 is rotatably mounted around a guide rail 52, and a contact portion 51a formed at the front of the carriage is configured to contact the sheet pressing plate 58 by its own weight.

The guide rail 52 is attached at a portion 52a to a left side plate 58 on which a motor 54 and the like are mounted, and is attached to a right side plate 59 at a portion 52b at the other end.

[Problems to be Solved by the Invention] In the recording apparatus, a scraping sound is generated when the carriage 51 slides on the guide rail 52, and this is caused by
There was a risk that the vibration would be transmitted from the portion 52b to the left side plate 58 and the right side plate 59, causing other members to resonate. In addition to the rubbing noise during sliding, rattling noise generated in the slight gap between the shaft hole of the carriage 51 and the guide rail 52 was also a source of noise.

On the other hand, vibrations generated from the motor 54 or a paper feed motor (not shown) attached to the left side plate 58 are transmitted to the guide rail 52, causing noise generated between the left side plate 58 and 52a, and between the right side plate 59 and the The drive source was the sound generated between the guide rail 52b and the shaft gap between the guide rail 52 and the carriage 51.

For example, in a recording device such as an inkjet recording device in which the sound of the recording head itself is low, the above-mentioned noise source may become particularly noticeable.

Furthermore, the above-mentioned vibrations are not only a problem as sound (but also cause a slight deterioration of recording accuracy. In other words, the above-mentioned vibrations are transmitted to the recording head 50 on the carriage 51, and by vibrating this, for example, inkjet recording In the head, slight differences are created in the flying direction of the droplets, which may shift the landing point of the droplets, which may lead to deterioration in recording.

[Means for Solving the Problems] The present invention for solving the problems described above provides a recording apparatus for recording on a recording medium, which includes a platen, a guide member provided along the platen, and a guide member provided along the guide member. The recording device is characterized in that it has a recording means that can reciprocate along the guide member, a support means for supporting the guide member, and an elastic body provided between the guide member and the support means.

[Operations] According to the present invention, it is possible to minimize the scraping noise, rattling noise, etc. that occurs when the recording means moves, and also to suppress vibrations transmitted from a drive source such as a motor to the guide member. This makes it possible to provide a recording device with low noise and high recording accuracy.

Further, below the conveyance roller 2a, as shown in FIG. 2, a paper pan 2f is attached which is curved along the circumferential surface of the conveyance roller 2a. The paper pan 2f extends to the manual feed port 12 and is configured to serve as a lower guide for the manually fed recording sheet l.

Further, upper guide plates 2g and 2h are attached above the paper pan 2f at a predetermined interval, and constitute a conveyance path for the recording sheet 1.

In the above configuration, when the conveyance motor 2e is driven to rotate the conveyance roller 2e in the direction of arrow a in FIG.
The recording sheet l fed from the front pinch roller 2b
, is nipped by the conveying roller 2a, is conveyed in a U-turn along the curve of the conveying roller 2a, and is further conveyed by the rear pinch roller 2.
b2 and the conveyance roller 2a, and is conveyed to the recording position located above.

On the other hand, the recording sheet 1 fed from the manual feed port 12 is nipped by the conveyance roller 2a and the rear pinch roller 2b2, and conveyed to the recording position.

Here, the recording sheet l is automatically fed to the conveying means 2 A.
SFII will be briefly explained.

This is removably attached to the recording device, and as shown in FIG.

When the roller rotates in the direction indicated by the arrow in the figure, one of the uppermost layers is separated and fed and comes into contact with the nip between the registration roller lid located downstream thereof and the upper roller lle pressed against it. and the registration roller 11. When d rotates in the direction of arrow C in FIG. 2, the recording sheet 1 is nipped by the registration roller lid and the upper roller lie which rotates following the registration roller lid, and is fed to the sheet conveying means 2.

The driving force transmission configuration to the registration roller lid includes a first

The tip of the sheet pressing member 3 is located below the recording position by the recording means 7, and the conveyed recording sheet 1 is pressed by the member 3 against the conveying roller 2a. As a result, the recording sheet 1 at the recording position will not be lifted off the platen 4.

Further, the front end of the carriage 5 is always in contact with the sheet pressing member 3, as will be described later.

(Carriage) The carriage 5 is for reciprocating the recording means 7 in the width direction of the recording sheet l.

The carriage 5 is slidably attached at both ends to guide rails 6 having a circular cross section and fixed to the left and right side walls 13a and 13b.

Further, the carriage 5 is attached to be rotatable about the guide rail 6, and is attached so that the front side of the carriage 5, that is, the side facing the recording sheet 1, is slanted forward.As a result, the carriage 1 and the carriage l The carriage is configured such that the front end of the carriage comes into contact with the sheet pressing member 3 due to the weight of the recording means 7 mounted thereon.

Here, the state in which the guide rail 6 is fixed to the left and right side walls 13a and 13b will be explained in detail with reference to FIG.

FIG. 3 is a cross-sectional view of the aforementioned fixing portion taken along the axis of the guide rail 6. As shown in FIG. Left end side 6a of guide rail 6
has a groove 6b that is one step smaller than the outer diameter of the guide rail 6.

Further, a hole with approximately the same diameter as the guide rail 6 is bored in the left side wall 13a, and the left side rubber ring 20 is fitted into the guide rail 6 on which the left rubber ring 20 is attached. Here guide rail 6
Only vibrations in the direction of the arrow a in the figure, that is, in the circumferential direction, can be transmitted between the left side plate 13a and the left side plate 13a, but this transmission is suppressed to a minimum by the left rubber ring 20.

Next, a groove 6d smaller than the outer diameter of the guide rail 6 is also provided on the right end side 6c of the guide rail 6, and a right rubber ring 21 is attached thereto. The diameter of the hole in the right side wall 13b is set to be smaller than the outer diameter of the guide rail 6, and the right rubber ring 21 has approximately the same outer diameter as the hole in the right side wall 13b when installed, and the guide rail 6 is attached at both ends of the rubber ring 21. There are flanges 21a and 21b that have an outer diameter that is approximately equal to the outer diameter.Therefore, if the guide rail 6 is misaligned in the left/right direction, it is attached to the right side wall 13b via the flange portions 21a and 21b of the right rubber ring 21. The structure is designed to prevent

Therefore, between the guide rail 6 and the left side plate 13a, not only the arrow direction in the figure, that is, the outer circumferential direction, but also the side direction
Although the structure is such that vibrations in the directions (directions) can also be transmitted, the transmission is suppressed to a minimum by the right rubber ring 21.

As shown in FIG. 1, a slit portion 22 is provided in the upper part of the shaft hole of the right side wall 13b, and the groove-shaped portion of the right end rubber ring 21 of the guide rail 6 shown in FIG. 3 is inserted into the slit portion 22. The structure is such that the elasticity of the periphery of the slit portion 22 of the right side wall 13b serves as a spring stopper.

(Transmission Means) The transmission means IO transmits the driving force of the carriage motor 9 to the carriage 5 in order to move the carriage 5 back and forth.

As shown in FIG. 1, its configuration is such that a drive pulley lOa is attached to one end of the movement range of the carriage 5, a driven pulley 10b is attached to the other end, and a carriage motor 9 is connected to the drive pulley 10a. are doing. Furthermore, an endless timing belt IOC is stretched parallel to the guide rail 6 between the pulleys 10a and 10b,
A part of this timing belt 10c is attached to the carriage 5.
is fixed.

Therefore, when the carriage motor 9 is driven forward and backward,
These driving forces are transmitted to the carriage 5 via the timing belt 10c, and the carriage 5 reciprocates along the guide rail 6.

(Recording Means) The recording means is mounted on the carriage 5 as described above, and records an ink image on the recording sheet l conveyed by the conveyance means 2. As the recording means in this apparatus, an inkjet recording method is suitably used.

The inkjet recording method includes a liquid ejection port for ejecting recording ink liquid as flying droplets, a liquid flow path communicating with the ejection port, and a part of this liquid flow path. and ejection energy generating means for providing ejection energy for causing the ink liquid to fly. The ejection energy generating means is then driven in accordance with the image signal to eject ink droplets and record an image.

Examples of the ejection energy generating means include a method using pressure energy generating means such as an electromechanical transducer such as a piezo element, and an electromagnetic energy generating means that generates flying droplets by irradiating and absorbing electromagnetic waves such as a laser into the ink liquid. There are two methods: a method using a thermal energy key generating means such as an electrothermal converter, and a method using a thermal energy generating means such as an electrothermal converter. Among these methods, a method using a thermal energy generating means such as an electrothermal converter is preferable because it allows the ejection ports to be arranged in a high density manner and also enables the recording head to be made compact.

Incidentally, as shown in FIG. 1, a capping means 18 is provided at the left end of the movement range of the carriage 5. The capping means 18 has the function of covering the ink ejection surface of the print head 7 during non-printing, thereby preventing the ink near the ejection ports of the print head 7 from drying out and from solidifying accordingly.

In addition, a pump (not shown) is connected to the capping means 18, and the pump is driven in order to prevent ink discharge failure, removal, or prediction thereof, and its suction force can suck ink from the discharge port to perform recovery processing. It has become.

(Discharging means) The discharging means 8 is the recording sheet l recorded by the recording means 7.
It is for discharging.

As shown in FIGS. 1 and 2, this configuration includes a discharge roller 8a and a spur 8b in contact with the discharge roller 8a. A discharge gear 8 is provided at the end of the roller shaft 8C of the discharge roller 8a.
d is attached, and this discharge gear 8d is the idle gear 2.
It meshes with d.

Therefore, when the conveyance motor 2e is driven, its driving force is transmitted to the discharge roller 8a, which rotates, and the recording sheet 1 is discharged by the cooperative action of the discharge roller 8a and the spur 8b. The discharged recording sheet 1 is transferred to a discharge stacker 8f located above the discharge roller 8a.

As described above, in this embodiment, both ends of the sliding guide rail 6 of the carriage 5 on which the recording head 7 is mounted are not directly fixed to the left and right side walls 13a, 13b, and as shown in FIG. As shown, since the carriage 5 is fixed via the left rubber ring 20 and the right rubber ring 21, vibrations from the carriage 5 are transmitted to the left and right walls 13a.

13b, and the left and right walls 13a, 13
It also prevents vibrations from being transmitted to the guide rail 6. Furthermore, the guide rail 6 and the left and right side walls 13a.

It also prevents the gap between 13b and 13b.

Furthermore, in this embodiment, the motor for driving the carriage 5, the carriage motor 9, the motor for paper feeding, and the conveyance motor 2e are attached to the left side wall 13a, which is a larger source of vibration than the right side wall 13b. You will have . Therefore, in this embodiment, the left side wall 13a
The side only receives the outer periphery of the guide rail 6,
lateral receiving or positioning on the right side wall 13b side;
The structure was designed to reduce the transmission of vibration as much as possible by stopping the parts from being pulled out.

In addition, in this embodiment, the rubber rings are 20°21 on the left and right sides.
It has a structure in which the rail and guide rail 6 are integrated, and the rail can be handled as a shaft with a rubber ring, making it easy to handle the rail during assembly or service.

[Other Embodiments] FIG. 4 shows a modification of the shape of the left rubber ring 20 of the fixing portion of the guide rail 6 in the embodiment of the box 1 described above.

That is, a groove 20c is provided along the circumference of the left rubber ring 20, and a groove 23 is provided in the circumferential direction of the left rubber ring 20, so that the contact portion with the left side wall 13a is a part of the circumferential ring. This makes the effect even more effective.

Further, in the embodiment shown in FIG. 5, the left rubber ring 20 is knurled to make the damping effect more effective, similar to the embodiment shown in FIG. In addition, the same effect can be obtained even if the shape of the left rubber ring 20 has a partial protrusion.

Further, in the embodiment shown in FIG. 6, a flange portion 20a is provided on the right side of the left rubber ring 20, so that it functions as a buffer material when the carriage 5 moves toward the left end due to some abnormality. .

Furthermore, FIG. 7 shows that the other embodiment described above has a guide rail 6.
While the left rubber ring 20a is attached to the left side, in this embodiment shown in FIG. 7, the left side is also attached to the guide rail 6! 13a is separated by the left rubber ring 20 and has a structure that does not transmit vibrations.

As explained above, according to the above-mentioned embodiment, by providing a member made of an elastic material between the guide member and the left and right side walls that support it, rattling noise generated between the guide rail and the carriage can be avoided. It was possible to minimize noise such as noise and scraping, and it was also possible to suppress vibrations transmitted to the guide rail from the drive source such as the motor. Furthermore, by suppressing the vibration of the guide rail, more accurate recording is possible, and a recording device with low noise and high recording accuracy has been realized.

It should be noted that the present invention, particularly when applied to an inkjet recording system, brings about excellent effects in the bubble jet recording head and recording apparatus proposed by Canon (2). This is because such a system can achieve higher recording density and higher definition.

As for typical configurations and principles thereof, it is preferable to use the basic principles disclosed in, for example, US Pat. No. 4,723,129 and US Pat. No. 4,740,796. This method can be applied to both the so-called on-demand type and continuous type, but especially in the case of the on-demand type, it is necessary to arrange the liquid (ink) in accordance with the sheet and liquid path that hold it. The electrothermal converter that is
Generating thermal energy in the electrothermal transducer to produce film boiling on the thermally active surface of the recording head by applying at least one drive signal that corresponds to recorded information and provides a rapid temperature rise above nucleate boiling. As a result, bubbles in the liquid (ink) can be formed in a one-to-one correspondence with this drive signal, which is effective. The growth and contraction of this bubble causes the liquid (ink) to be ejected through the ejection opening, forming a small amount (at least one ink).If this drive signal is in the form of a pulse, the growth and contraction of the bubble will occur immediately and appropriately. This makes it possible to achieve ejection of liquid (ink) with particularly excellent responsiveness, which is more preferable.As this pulse-shaped drive signal,
U.S. Pat. No. 4,463,359, U.S. Pat. No. 4,345,26
Those described in Specification No. 2 are suitable.

Furthermore, if the conditions described in US Pat. No. 4,313,124 concerning the invention regarding the temperature increase rate of the heat acting surface are adopted, even more excellent recording can be performed.

The configuration of the recording head includes, in addition to the combination configuration of ejection ports, liquid paths, and electrothermal converters (straight liquid flow path or right-angled liquid flow path) as disclosed in the above-mentioned specifications, a heat acting section. The present invention also includes configurations using US Pat. No. 4,558,333 and US Pat. No. 4,459,600, which disclose configurations in which the wafer is placed in a bending region. In addition, JP-A-59 discloses a configuration in which a slit common to a plurality of electrothermal converters is used as a discharge part of the electrothermal converters.
-123670 and Japanese Patent Application Laid-Open No. 59/1989 disclosing a configuration in which a discharge portion is made to correspond to an opening that absorbs pressure waves of thermal energy.
The effects of the present invention are also effective even if the structure is based on the publication No.-138461. That is, regardless of the form of the recording head, according to the present invention, recording can be performed reliably and efficiently.

Furthermore, 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 that can be recorded by a recording apparatus. Such a recording head may have either a configuration in which the length is satisfied by a combination of a plurality of recording heads, or a configuration as a single recording head formed integrally. Furthermore, the size of the reading area used for actual correction and the area to provide extra space can also be appropriately selected.

In addition, even serial types such as upper tsuba can be used as a recording head fixed to the device body, or by being attached to the device body, electrical connection to the device body and ink supply from the device body can be made. The present invention is also effective when using 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.

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, to the present invention, because the effects of the present invention can be further stabilized. Specifically, these include capping means for the recording head, cleaning means, pressure or suction means, preheating means using an electrothermal transducer or another heating element, or a combination thereof; It is also effective to perform a preliminary ejection mode in which ejection is performed separately from printing in order to perform stable printing.

In addition, regarding the type and number of recording heads installed, for example, in addition to one type that corresponds to single-color ink, there is also a plurality of recording heads that correspond to multiple inks with different recording colors and densities. It may be something that can be done. That is, for example, the recording mode of the recording apparatus is not limited to a recording mode for only a mainstream color such as black, but may also be a recording mode in which the recording head is configured integrally or in a combination of multiple colors, The present invention is also extremely effective for devices equipped with at least one full color by color mixture.

Additionally, in the embodiments of the present invention described above,
Although ink is described as a liquid, it is an ink that solidifies at room temperature or below, but softens or liquefies at room temperature, or in an inkjet method, the ink itself is
Generally, the temperature is adjusted within the range of 0°C or more and 70°C or less so that the viscosity of the ink is within the stable ejection range, so if the ink is in a liquid state when the recording signal is applied, good. In addition, the temperature increase caused by thermal energy can be actively prevented by using it as energy for changing the state of the ink from a solid state to a liquid state.
Alternatively, ink that solidifies when left unused is used to prevent ink evaporation, and in either case, the ink is liquefied by applying thermal energy in response to a recording signal, and the liquid ink is ejected, or the recording medium The present invention is also applicable to the case of using inks that are liquefied only by thermal energy, such as those that already begin to solidify at the time of reaching . Ink in such cases is disclosed in Japanese Patent Application Laid-open No. 54-56847 or Japanese Patent Application Laid-open No. 60-71.
In a state where it is held as a liquid or solid in the porous sheet recesses or through holes, as described in Japanese Patent No. 260,
It may also be configured to face the electrothermal converter. In the present invention, the most effective method for each of the above-mentioned inks is to implement the above-mentioned film boiling method.

In addition, the inkjet recording apparatus of the present invention can be used as an image output terminal for information processing equipment such as a computer, or as a copying apparatus combined with a reader or the like, or as a facsimile apparatus having a transmitting and receiving function. It may also be something that takes .

[Effects of the Invention] According to the present invention described in detail, it is possible to provide a recording device with low noise and improved recording accuracy.
