DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail with reference to the drawings.

[First Embodiment] FIGS. 1 to 4 show a cable holding mechanism and a recording apparatus according to the first embodiment. FIG. 1 is an explanatory view of the cable holding mechanism, and FIG. 2 is a recording apparatus. 3 is a perspective explanatory view of an information processing device using the recording device. Here, as the order of description, the overall configurations of the recording device and the information processing device will be described first, and then the cable pressing mechanism used for this will be described.

[Overall Structure of Recording Apparatus] In FIG. 2, a carriage 1 is mounted on a head cartridge 4 in which a recording head 2 constituting a recording means and an ink tank 3 are connected. One end of the carriage 1 on the recording head 2 side is fitted to a lead screw 6 rotatably attached to the chassis 5 so as to be slidable in the axial direction.
A guide portion is provided at the other end of the carriage 1, and the guide portion is slidably fitted in a guide rail 5a formed on the chassis 5 in parallel with the axial direction of the lead screw 6.

The carriage 1 is constructed so as to be capable of reciprocating in the axial direction thereof as the lead screw 6 rotates while the posture thereof is always kept constant.

That is, as shown in FIG. 2, the lead screw 6 has a screw gear G3 fixed to the left end of the screw and a pinion gear G1 fixed to the output shaft of the carriage motor 7 and meshes with each other. A lead pin (not shown) attached to the carriage 1 is fitted in a guide strip 6 a formed in a spiral shape at 6 with a predetermined pitch. Therefore, when the lead screw 6 rotates with the forward rotation and the reverse rotation of the carriage motor 7, the carriage 1 reciprocates.

In synchronization with the reciprocating movement of the carriage 1,
By driving the recording head 2 and ejecting ink in accordance with a recording signal, one line recording is performed on the recording material 8. That is, the recording head 2 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 droplet forming energy that acts on the liquid in the acting portion. Equipped with generating means.

As the energy generating means for generating such energy, a recording method using an electromechanical transducer such as a piezo element, electromagnetic waves such as a laser are radiated 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 technology and 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.

When one line is recorded by scanning the carriage 1, the recording medium 8 is conveyed by one line by the conveying means and the next line is recorded. The conveyance of the recording medium 8 is performed by the conveyance roller 9. And pinch roller 10 that presses against this
And the pair of rotating bodies of the discharge roller 11 and the spur 12 that abuts on the discharge roller 11.

To explain this in detail, the recording material 8 whose recording surface faces the ejection opening surface of the recording head 2 is brought into pressure contact with the conveying roller 9 by the pinch roller 10, and the conveying roller 9 causes the conveying motor 13 to move. By appropriately rotating by, the paper is conveyed to the recording position as needed. After the recording, the recording material 8 is pressed against the discharge roller 11 by the spur 12 and is discharged and conveyed outside the apparatus by the rotation of the discharge roller 11. The transport roller 9 and the discharge roller 11 are driven by the transport motor 13, but the driving force is transmitted by the reduction gear train G2.

A spur that contacts the recording surface side of the recording material 8
The position of the rotation axis of 12 is fixed, and the contact position between the spur 12 and the recording material 8 does not change regardless of the thickness of the recording material 8, while the contact position of the recording material 8 contacts the non-recording surface side of the recording material 8. Discharge roller
The discharge roller 11 is deformed according to the thickness of the recording material 8 so as to respond to the change in the thickness of the recording material 8. Specifically, the discharge roller 11 is made of thin rubber,
It is formed in a conical shape and deforms with a restoring force in the radial direction.
Therefore, the deformation is performed according to the pressure contact force against the spur 12 and the thickness of the recording material 8.

The same effect can be obtained by forming the discharge roller 11 from a material having a large elastic deformation, such as a porous sponge, a resin having a very low hardness, or a rubber. The entire discharge roller 11 may be pressed against the spur 12 by a spring or the like.

Therefore, regardless of the thickness of the recording material 8, it is possible to stably convey the recording material by keeping the distance between the recording head 2 and the recording material 8 at a predetermined amount.

Further, in FIG. 2, 14 is a paper sensor, which detects the presence or absence of the recording material 8. Reference numeral 15 is a flexible cable made of a material having good bending resistance such as polyimide, which connects the apparatus main body A and the carriage 1 to each other.
A recording signal is transmitted from the electric circuit to the recording head 2 mounted on the carriage 1. One end of the flexible cable 15 is held by the pinch roller frame 17 by the cable holder 16.

A cable pressing member 18 is guided by the lead screw 6 which is a guide shaft of the carriage 1 and is moved between the left and right bearings 2a and 2b (see FIG. 1) for inserting the carriage 1 into the lead screw 6. It is freely inserted. The operation of the cable pressing member 18 will be described later.

Reference numeral 19 is an ink tank lever for attaching and detaching the ink tank 3 on the carriage 1.

The recording apparatus of this embodiment has a home position where the carriage 1 is closest to the carriage motor 7 side and a carriage position shown in FIG.
The carriage 1 can be stopped at two positions of the ink tank 3 or the replacement position where the head cartridge 4 is attached or detached (however, because of the reversal of the scanning direction of the carriage 1 during the recording operation, or the apparatus main body). Except for the stop to wait for the recorded data to be transferred from). The ink tank lever 19 is operated in the exchange position.

In FIG. 3, reference numeral 20 is a printer unit equipped with the above-described recording device, and 21 is a keyboard unit equipped with keys for inputting characters and the like and keys for giving various commands. , 22 is a display unit equipped with a display for displaying the input information and the like. Further, 23 is a printer opening opened in the housing for operating the printer unit 20 from the outside, and 24 is a printer lid for closing the printer unit 20 when there is no need to operate the printer unit 20. When operating the ink tank 3, the control key of the keyboard portion 21 is operated, or the carriage 1 is moved to the replacement position according to a software instruction, the printer lid 24 is opened, and the operation is performed through the opening 23. .

{Cable Holding Mechanism} Next, a cable holding mechanism for holding the flexible cable 15 will be described.

First, FIG. 4 shows a state of the flexible cable 15 when the cable holding member is not used. In this case, one end of the flexible cable 15 is held by the cable holder 16 and the other end of the flexible cable 15 is held by the carriage 1 and moves while being deformed as the carriage 1 moves. At this time, since the flexible cable 15 repeatedly bends as the carriage 1 moves, the flexible cable 15 is made of a material having good bending resistance, such as polyimide. These materials are
Since the rigidity of the flexible cable 15 is relatively high, as shown in FIG.
Is deformed into a shape with a large bending radius.

As described above, the flexible cable 15 is
If a large bending radius is used, flexible cable 15
When the ink tank lever 19 or the like is operated, the operator's finger or the like is touched, the operability deteriorates, and in the worst case, the cable 15 may be disconnected. is there. Further, the flexible cable 15 may come into contact with the guide rail 5a, or may come into contact with other constituent members of the recording apparatus, which may hinder the operation.

In order to prevent the above obstacles, in this embodiment, as shown in FIG. 1, a cable pressing member 18 for restricting the moving range of the flexible cable 15 is provided.

When the carriage 1 is at the home position, the cable pressing member 18 is located on the right bearing 2b side as shown in FIG. 1 (a). When the recording operation is started or the movement to the exchange position is instructed from this state, the lead screw 6 rotates and the carriage 1 advances in the direction of arrow b in FIG. At this time, since the cable pressing member 18 is only lightly inserted into the lead screw 6, the cable pressing member 18 is not moved by the rotation of the lead screw 6. Therefore, immediately after the carriage 1 starts moving, the cable pressing member 18 stays in its place, and the cable pressing member 18 moves.
It moves relative to the left (toward the left bearing 2a).

When the cable holding member 18 comes into contact with the left bearing 2a by the movement of the carriage 1, the cable holding member 18 receives a force from the carriage 1 and moves in the direction of arrow b with the movement of the carriage 1. . While the carriage 1 continues to move in the direction of the arrow b, the relative positional relationship between the cable pressing member 18 and the carriage 1 does not change. At this time, the right end of the cable pressing member 18 is configured so as to hardly protrude from the right end of the carriage 1 (see FIG. 1B).

Therefore, as shown in FIG. 1B, even if the carriage 1 reaches the right end of its scanning range, the cable pressing member 18 does not interfere with the operation of the carriage 1.

Next, as described above, when the carriage 1 moves to the right end of the scanning range, reverses from it and starts moving to the left, immediately after that, the moving force is not applied to the cable pressing member 18 again. That is, until the cable pressing member 18 contacts the right bearing 2b, the cable pressing member 18 tries to stay there even if the carriage 1 moves.

When the cable holding member 18 comes into contact with the right bearing 2b due to the movement of the carriage 1, the cable holding member 18 receives a force from the carriage 1 and moves in the direction of arrow a as the carriage 1 moves. . At this time, the flexible cable 15 tries to rise to form a large loop due to its rigidity, but the cable pressing member
18 protrudes to the right, and the floating of the flexible cable 15 is suppressed (see FIG. 1A).

When the cable holding member 18 holds the flexible cable 15 from rising, the rigidity of the cable 15 applies a force F1 shown in FIG.
Is to be separated from the right bearing 2b. When the cable pressing member 15 is separated from the right bearing 2b by this force F1, even if the carriage 1 returns to the home position, the cable pressing member 18 cannot move to the state shown in FIG. The holding effect decreases.

Therefore, in this embodiment, the relationship between the frictional force F2 (see FIG. 1A) generated by the insertion of the lead screw 6 and the cable pressing member 18 and the force F1 is as follows.
It is set so that F1 <F2.

As a result, even when the flexible cable 15 and the cable holding member 18 are in contact with each other, the cable holding member 18 acts to hold down the flexible cable 15, and the carriage 1 moves in the direction of the arrow in FIG. 1 (a). The cable pressing member 18 moves relatively to the right bearing 2b side with respect to the carriage 1 as the cable pressing member 18 is reversed and moved from the b direction to the a direction.

The cable holding member 18 is the right bearing 2b.
When it comes into contact with the carriage 1, it receives a force from the carriage 1 and moves in the direction of the arrow a together with the carriage 1. Therefore, the flexible cable 15 is pressed by the cable pressing member 18, and lifting is restricted.

In order to replace the ink tank 3 and the like,
When the carriage 1 is moved from the home position to the exchange position (movement in the direction of arrow b in FIG. 1), the cable pressing member 18 is not at the position for pressing the flexible cable 15 (the position for contacting the right bearing 2b) as it is.
Therefore, in the present embodiment, when replacing the ink tank 3 or the like, the carriage 1 is moved from the home position in the direction of the arrow b so as to overshoot the replacement position, then reversed and moved for a while, and then the carriage 1 is moved to the replacement position. I'm trying to stop. As a result, the cable pressing member 18 is located at the position where it abuts on the right bearing 2b, so that the flexible cable 15 is pressed to prevent it from floating, and the operator does not touch the flexible cable 15 when replacing the ink tank 3 or the like. Can be prevented.

[Second Embodiment] In the first embodiment described above,
Depending on the moving direction of the carriage 1, the cable pressing member 18
The position has changed, but as in the second embodiment described below,
The flexible cable 15 may be constantly pressed except when the carriage 1 is at the right end of the moving area.

FIG. 5 is an explanatory view of the structure of the cable pressing mechanism according to the second embodiment. The members having the same functions as those in the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

The cable holding mechanism according to the second embodiment is different from the first embodiment in that the cable holding member 18 is pressed by the pressing spring 25. That is, FIG. 5 (a)
As shown in FIG. 5, the normal cable pressing member 18 is biased by the spring 25 and is in contact with the right bearing 2b.
The urging force F3 of the cable pressing member 18 by the spring 25 is F1 in comparison with the force F1 received by the cable pressing member 18 due to the rigidity of the flexible cable 15 described above.
<F3 relationship is set.

Due to the above-mentioned force relationship, the cable pressing member 18 is not pushed back by the flexible cable 15.

Then, when the carriage 1 comes to the right of the moving area, as shown in FIG.
The tip of 18 abuts on the chassis 5, and the external force causes the cable pressing member 18 to move toward the left bearing 2a side against the bias of the spring 25. At this time, the cable pressing member 18
Does not hinder the movement of the carriage 1.
A rotational force of the carriage motor 7 and a force F4 for moving the carriage 1 via the lead screw 6 and the lead pin;
The urging force F3 of the spring 25 is set to have a relationship of F3 <F4. As a result, the carriage 1 can be smoothly moved over the entire movement area without hindering the rotation of the carriage motor 7.

As described above, by adding the spring 25 to the structure of the first embodiment, the flexible cable 15 is lifted regardless of the moving area and moving direction of the carriage 1 and without hindering the movement of the carriage 1. You can hold it down.

[Third Embodiment] In the above-described first and second embodiments, an example in which the cable pressing member 18 is guided by the lead screw 6 has been shown, but the present invention is not limited to this, and the carriage itself can be used for guiding. It is also possible to adopt such a configuration.

The configuration will be described as a third embodiment with reference to FIG. The members having the same functions as those in the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 6, the cable pressing member 26 is attached to the carriage 1 so as to be rotatable about a shaft 27. Then, it is biased in the direction of arrow c in FIG. 6 by a spring (not shown) and stopped at a position substantially parallel to the lead screw 6 by a stopper (not shown). The force F5 that urges the cable pressing member 26 of the spring has a relationship of F1 <F5 with the force F1 received from the rigidity of the flexible cable 15 described above. By having this relationship, the cable pressing member 26 is not pushed back by the flexible cable 15.

At the position of the chassis 5 located in the right end moving area of the carriage 1, the cable pressing member 26 is provided.
A guide member 28 for guiding the rotation of the is fixed. The guide member 28 has a groove bent in an arc shape so as to guide the tip end of the cable pressing member 26 upward in FIG.

In the above arrangement, the carriage 1 is shown in FIG.
In the state of (a), the cable pressing member 26 is in a collapsed state, and suppresses the floating of the flexible cable 15. Then, as shown in FIG. 6B, when the carriage 1 comes to the right side of the moving area, the cable pressing member
The tip end of 26 abuts on the guide member 28, and the tip end of the cable pressing member 26 is rotated 90 degrees along the guide groove by the external force thereof to stand up and is stored so as to contact the right end side surface of the carriage 1.

When the cable pressing member 26 rotates, the rotational force of the carriage motor 7 is changed to a force F4 for driving the carriage 1 via the lead screw 6 and the lead pin so that the operation of the carriage 1 is not disturbed. ,
The force relationship with the force F5 for urging the cable pressing member 26 by the spring is set so that F4> F5.

With this setting, the rotation of the carriage motor 7 is not hindered and the carriage 1
Can move smoothly over the entire range of movement.

As described above, by attaching the cable pressing member 26 to the carriage 1 and urging the cable pressing member 26 with the spring, the carriage 1 is flexible regardless of the carriage moving region and the moving direction and without hindering the operation of the carriage 1. It is possible to prevent the cable from rising.

[Other Embodiments] In the above-mentioned embodiments, the ink jet recording system is used as the recording means, but the electrothermal converter is energized according to a recording signal, and the thermal energy applied by the electrothermal converter is changed. It is more preferable that the recording is performed by ejecting the ink from the ejection port due to the growth and contraction of the bubbles generated in the ink by utilizing the film boiling 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 gives 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 openings 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, which is an invention relating to the rate of temperature rise on 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 ejection 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.

Japanese Patent Laid-Open Publication No.
The effect of the present invention is effective even if the configuration is based on Japanese Patent Laid-Open No. 59-138461. That is, according to the present invention, recording can be surely and efficiently performed regardless of the form of the recording head.

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 a recovery means for the recording head, a preliminary auxiliary means, etc., which are provided as a constituent of the recording apparatus of the present invention, because the effects of the present invention can be further stabilized. Specifically, these are capping means, cleaning means, pressurizing or suctioning means for the recording head, preheating means by electrothermal conversion type or other heating element or a combination thereof, and recording. It is also effective to perform a stable recording by performing a preliminary discharge mode in which another discharge is performed.

Regarding the type and 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 with at least one of the full colors according to

In addition, in the above-mentioned embodiments, the ink is described as a liquid, but it is an ink that solidifies at room temperature or lower and softens or liquefies at room temperature, or in the ink jet recording system. 30 inks
Generally, the temperature is controlled in the range of ℃ to 70 ℃ to control the temperature of the ink so that the viscosity of the ink is within 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 the solid state to the 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 applying heat energy according to the recording signal and liquid ink is ejected, or when the ink reaches the 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 described in JP-A-54-5.
As described in Japanese Patent No. 6847 or Japanese Patent Laid-Open No. 60-71260, a mode in which it is opposed to the electrothermal converter in a state of being held as a liquid or a solid in the concave portion or through hole of the porous sheet. 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 device, besides the one used as an image output terminal device of an information processing equipment such as a computer, a form of a copying device combined with a reader or the like, and a form of a facsimile device having a transmitting / receiving function. It may be one that takes

Although an example using an ink jet recording system as the recording means has been described above, the present invention need not be limited to the ink jet recording system, and other thermal transfer recording systems, thermal recording systems, and Can also be applied to an impact recording method such as a wire dot recording method or another recording method.

Further, the above-mentioned cable pressing mechanism can be applied not only to a serial type recording apparatus, but also to a reading apparatus or the like in which, for example, a carriage is equipped with an optical system reading means and the carriage is scanned to read document information. It is possible.
