Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping mechanism for removing dirt due to ink droplets or the like on the ejection port surface of a recording head of an ink jet recording apparatus, and more particularly to a microminiature recording such as a recording apparatus of a printer-integrated camera. The present invention relates to stabilization of a wiping speed of a recording apparatus having a head.

[0002]

2. Description of the Related Art Conventionally, as a wiping mechanism of a serial type ink jet recording apparatus, a vertically movable wiper is moved to a position where it comes into contact with an ejection opening surface of a recording head mounted on the carriage to scan the carriage. Therefore, many simple mechanisms for wiping the discharge port surface with a wiper have been adopted. This mechanism is called "lateral wiping".

FIG. 18 is a diagram for explaining the relationship between the scanning position and the wiping load in the wiping mechanism utilizing the scanning operation of the carriage. (A)-(e)
Shows the positional relationship between the wiper C106 and the carriage B104 during the scanning operation of the carriage B104. The graph schematically shows changes in the wiping load of the carriage in the positional relationships shown in (a) to (e). The wiping load is a load due to elastic force and frictional force generated by the carriage coming into contact with the wiper during wiping.

(A) is a position where the carriage B104 starts to contact the wiper C106. From here, the carriage B104 scans toward the position shown in (b) and gradually deforms the wiper C106, so that the reaction force due to the elasticity of the wiper C106 gradually increases.
Then, in the state shown in (c), the wiping load reaches the maximum value.

After passing through the position shown in (c), the direction of the elastic reaction force of the wiper C106 is changed to the carriage B10.
4, the wiping load sharply decreases because it becomes a direction (upward in the figure) orthogonal to the scanning direction of 4, and maintains a substantially constant value up to the position shown in (e). When the position shown in (e) is passed, the carriage B104 moves to the wiper C10.
Since it is separated from 6, the wiping load becomes "0".

Since it is necessary to set the scanning speed to an appropriate speed in order to perform good wiping, a speed command is given to the motor for driving the carriage B104 with the appropriate scanning speed as the target speed.

FIG. 19 is a diagram showing how the wiping speed changes in the conventional ink jet recording apparatus.
(A) to (e) of FIG. 19 correspond to (a) to (e) of FIG. The wiping load described with reference to FIG. 18 is shown by a dotted line in FIG. 19, the speed command value is shown by a thick solid line, and the actual scanning speed is shown by a thin solid line.

In the conventional general ink jet recording apparatus, since at least several tens of CC or more of ink is loaded on the scanning carriage in addition to the recording head, the weight of the carriage is about 100 grams or more. Therefore, the “inertial force associated with the mass of the carriage and its drive system” and the “motor generated torque” are sufficiently large, and as shown in FIG. 19, even if the wiping load changes, the contact with the wiper blade may occur. The fluctuation of the scanning speed caused by the increase of the wiping load of the carriage resulting from this was slight and did not pose a problem.

[0009]

In recent years, there is an increasing tendency to demand portability for recording devices. For example, a so-called digital camera, which can immediately display an image captured by an optical system on a screen and can also store the image data in a storage medium, is rapidly spreading. It is considered to incorporate a recording function in this digital camera.

In order to realize an ultra-compact and lightweight recording device built in a digital camera, the ink tank mounted on the carriage is limited to the ink amount capable of printing one or several sheets of paper. Miniaturized to size, the carriage is miniaturized to a mass of a few grams. As a result, it becomes possible to select an ultra-small motor for driving the carriage for scanning.

However, when the ink tank and the carriage are miniaturized and the motor is miniaturized, a problem which has not existed in the past has occurred. That is, an increase in load due to contact with the wiper blade has become a problem.

FIG. 20 is a diagram showing how the wiping speed fluctuates in a conventional recording apparatus in which the carriage is downsized. (A) to (e) in the figure are (a) to (e) in FIG.
Corresponds to (e). The wiping load described with reference to FIG. 18 is shown by a dotted line in FIG. 20, the speed command value is shown by a thick solid line, and the actual scanning speed is shown by a thin solid line.
Referring to FIG. 20, since the wiping load increases from the section (a) to the section (c), the scanning speed is 10% of the target.
The speed is reduced to less than half with respect to 0 mm / sec. Next, when the carriage passes the position (c) and the wiping load is suddenly lightened, the operation speed exceeds the target speed and rises to near 150 mm / sec.

As described above, the wiping speed of the miniaturized carriage is unstable. If the wiping speed is unstable, the function of cleaning the face surface of the recording head is remarkably deteriorated by wiping, which deteriorates the printing quality and is inconvenient.

In order to avoid this problem, it is possible to increase the inertial force by attaching a weight to the carriage or the motor shaft. Further, it is conceivable to increase the obtained torque by increasing the size of the motor. But,
These are inconvenient because they go against the original purpose of reducing the size and weight of the recording apparatus.

It is an object of the present invention to provide a recording apparatus which scans a small and lightweight carriage stably against a change in wiping load.

[0016]

In order to achieve the above object, an ink jet recording apparatus of the present invention has a recording head having an ejection port surface having at least one ejection port for ejecting ink droplets, The recording head and the recording material are moved relative to each other to perform recording, the removing member is brought into contact with the ejection port surface, and the removing member and the ejection port surface are moved relatively to each other to eject the ejection port. In an inkjet recording apparatus having a mechanism for removing unwanted matter on the surface, before the removing member contacts the ejection port surface, the relative speed between the removing member and the ejection port surface is determined by measuring the relative velocity between the removing member and the ejection port surface. It is characterized by having a control device for controlling to a second speed which is higher than a first speed which is a relative speed between the removing member and the discharge port surface suitable for removing the.

Therefore, before the removing member comes into contact with the discharge port surface, the removing member and the discharge port surface move relatively at a relative speed sufficiently higher than the speed suitable for removing the unwanted matter. Therefore, since the inertial force is small, even if the relative speed decreases when the removing member and the discharge port surface start to contact with each other, it does not decelerate to an inappropriate speed.

The control device guides the relative speed between the removing member and the discharge port surface from the second speed to the first speed when the removing member starts to contact the discharge port surface. May be controlled as follows.

Therefore, the control device controls so as to reduce the relative speed between the removing member and the discharge port surface in accordance with the deceleration caused by the contact between the removing member and the discharge port surface. The relative speed of can be smoothly brought close to the first speed suitable for removing the unwanted matter.

Further, the control unit guides the relative speed between the removing member and the discharge port surface from the second speed to the first speed through a plurality of stages of deceleration with different decelerations. You may control to.

Therefore, since the relative speed between the removing member and the discharge port surface is gently decelerated, overshoot and undershoot are reduced, and the control device can control the relative speed almost according to the speed command.

Further, the deceleration process may have two stages.

Further, the two-stage deceleration process includes the second step.
From the first speed to a third speed that is higher than the first speed with a predetermined first deceleration, and from the third speed to the first speed, the first speed. It may be a second deceleration process of decelerating at a second deceleration smaller than the deceleration.

Further, the control device controls the third speed so that the relative speed between the removing member and the discharge port surface becomes the first speed due to the undershoot generated after the first deceleration process. You may choose.

Therefore, since the relative speed between the removing member and the discharge port surface is controlled to the first speed by the command from the control device and the undershoot, the relative speed is achieved by the undershoot after reaching the first speed. Is not lowered more than necessary.

Further, the control device selects the second deceleration so that the relative speed between the removing member and the discharge port surface is maintained at the first speed when returning from the undershoot. May be.

Therefore, since the relative speed between the removing member and the discharge port surface is maintained at the first speed when returning from the undershoot, overshoot does not occur and the relative speed is quickly stabilized at the first speed.

The removing member is a member made of a material which has elasticity and is deformable by an external force. In the process of removing the unwanted matter by the removing member, the removing member acts as the discharge port surface. There may be a deformation process in which the removal member starts to come into contact with each other and gradually deforms against the elasticity of the removal member, and a wiping process in which the removal member having the shape completely deformed in the deformation process slides on the ejection port surface.

The controller reduces the relative speed between the removing member and the discharge port surface to the third speed in the deforming process by the first deceleration process, and in the wiping process, the relative speed between the removing member and the discharge port surface is reduced to the third speed. The first speed may be maintained after the relative speed is reduced to the first speed by the deceleration process of 2.

Therefore, since the control device raises the relative speed to the sufficiently high second speed before the deformation process, when the inertial force loses the reaction force and the deceleration occurs, the control unit removes the unnecessary substances. Since it is possible to approach the suitable first speed and the deceleration is relaxed when the speed is lowered to the third speed,
The undershoot can bring the relative speed to the first speed, and the first speed is maintained when returning from the undershoot.

Further, the control device may select a deceleration applied to the removing member in the deformation process as the first deceleration.

Therefore, the control device controls so as to lower the relative speed in accordance with deceleration due to the deceleration applied to the removing member during the deformation process, so that the first speed, which is suitable for removing the unwanted matter, can be smoothly approached. You can

Further, it may be a serial type ink jet recording apparatus in which the recording head is mounted on a carriage capable of reciprocating along a scanning path.

Further, a means for moving the removing member to a position in contact with the ejection port surface of the recording head is provided, and the carriage is scanned while the removing member is moved to a position in contact with the ejection port surface. The discharge member surface may be wiped by the removing member by operating.

At, proportional, integral and derivative operations are performed. The proportional, integral, and derivative calculation results are added by the adder d4 and then amplified.

More specifically, the proportional calculator d1 multiplies the speed error by the gain Gp. The integral calculation unit d2 integrates the velocity error and multiplies the integral value by the gain Gi. The differential operation part d3 differentiates the speed error and multiplies the differential value by the gain Gd. Then, the output values of the respective calculation units d1, d2, d3 are summed in the addition unit d4, multiplied by the gain G, and the result is supplied to the motor driver b4 as a voltage value for driving the motor b5 (Fig. 9).

On the other hand, when the carry motor M002 rotates in the reverse direction, the switching slider B211 and the switching cam B2 are moved.
The pressure plate head B 213 and a lock mechanism (not shown) are driven via 12 and the driving force is transmitted to the sheet feeding roller C 110 on the side of the media pack C 100. That is, the pressure plate head B213 passes through the window portion C102A (see FIG. 4) of the shutter C102 of the media pack C100 by the driving force of the transport motor M002 at the time of reverse rotation,
The print medium C104 accumulated in the media pack C100 is pressed downward in FIG. As a result, the print medium C104 at the lowest position in FIG. 4 is pressed against the paper feed roller C110 in the media pack C100. In addition, a lock mechanism (not shown) is a transport motor

In this way, the conveyance motor M002 rotates in the reverse direction so that only one print medium C104 is taken out from the media pack C100 in the direction of arrow C in FIG. 9, and then the conveyance motor M002 rotates in the normal direction. The print medium C104 is conveyed in the direction of arrow B.

FIG. 16 is an explanatory diagram of signal processing in the printer section B100.

The image reproduced on the camera unit A100 side, that is, the image read from the CF card 105 is JPEG-decompressed by the ASIC 103 and resized to a resolution suitable for printing, as shown in FIG. Then, the resized image data (YUV) is sent to the printer unit B100 via the interface unit 210. The printer unit B100 performs image processing on the image data sent from the camera unit A100 by the image processing unit 201,
As shown in FIG. 16, conversion of image data into RGB signals, input γ correction according to camera characteristics, color correction and color conversion using a look-up table (LUT), and binarized signal for printing. To convert. In the binarization process, the second memory 202 is used as an error memory in order to perform the error diffusion (ED) process. In the present embodiment, the binarization processing unit in the image processing unit 201 performs error diffusion processing, but it is also possible to perform other processing such as binarization processing using a dither pattern.

The binarized print data is temporarily stored in the band memory 204 by the band memory control unit 203. Encoder counter 2 of printer unit B100
09, each time the carriage B 104 equipped with the recording head 207 and the encoder 208 moves by a fixed distance,
The encoder pulse from the encoder 208 enters. Then, in synchronization with this encoder pulse, the band memory 2
04 and the mask memory 205, the print data is read out, and based on the print data, the head controller 20
6 controls the recording head 207 to record an image.

The band memory control in FIG. 16 will be described.

The plurality of nozzles in the recording head 207 are formed in rows so as to have a density of 1200 dpi, for example. When the carriage is scanned once in order to record an image using the recording head 207, the number of nozzles in the sub-scanning direction (hereinafter, also referred to as “vertical (Y direction)”) and the main scanning direction (hereinafter, “ , "Horizontal (X direction)"), it is necessary to create print data for one print area (print data for one scan) in advance. In the block diagram of FIG. 14, the recording data is created by the image processing unit 201, and the band memory control unit 20
3 is temporarily stored in the band memory 204. After the print data for one scan is stored in the band memory 204, the carriage is scanned in the main scanning direction. At that time, the encoder pulse input from the encoder 208 is counted by the encoder counter 209, the print data is read from the band memory 204 according to the encoder pulse, and an ink droplet is ejected from the print head 207 based on the image data. It Recording head 20
When a bidirectional recording method of recording an image (forward recording and backward recording) during forward scanning and backward scanning of 7 is adopted, image data is read from the band memory 204 according to the scanning direction of the recording head 207. . For example, the address of the image data read from the band memory 204 is sequentially incremented during the forward pass recording, and the address of the image data read from the band memory 204 is sequentially decremented during the backward pass recording.

Actually, when the image data (C, M, Y) created by the image processing unit 201 is written in the band memory 204 and the image data for one band is prepared, the scan of the recording head 207 is performed. Is possible. Then, the recording head 207 scans, the image data is read from the band memory 204, and the image is recorded by the recording head 207 based on the image data. During the recording operation,
Image data to be recorded next is created by the image processing unit 201, and the image data is written in the area of the band memory 204 corresponding to the recording position.

As described above, the band memory control is performed by the recording data (C, M, Y) created by the image processing unit 201.
Is written in the band memory 204 and the operation of reading the print data (C, M, Y) from the band memory 204 in order to send the print data (C, M, Y) to the head control unit 206 according to the scanning operation of the carriage is switched.

The mask memory control in FIG. 16 will be described.

This mask memory control is necessary when the multi-pass printing method is adopted. In the case of the multi-pass printing method, a print image for one row having a width corresponding to the length of the nozzle row of the print head 207 is printed by dividing the print head 207 into a plurality of scans. That is, the carry amount of the print medium that is intermittently carried in the sub-scanning direction is 1 / N of the length of the nozzle row. For example, when N = 2, the print image for one row is scanned twice. (N = 4), and when N = 4, the print image for one line is divided into four scans and printed (four-pass print). Similarly, when N = 8, 8-pass printing is performed, and when N = 16, 16-pass printing is performed. Therefore, the recording image for one line is recorded on the recording head 207.
Will be completed by multiple scans of.

Actually, the mask memory 205 stores mask data for assigning the image data to the scanning of the recording head 207 a plurality of times, and the mask data and the image data are logically ANDed. Based on this, the recording head 207 ejects ink to record an image.

Also, in FIG. 16, the CF card 105
The voice data stored in the printer is transmitted by the ASIC 102 to the printer unit B100 via the interface 210 in the same manner as the image data. Printer unit B100
The audio data sent to is encoded by the audio encoder 230 and recorded as code data in the image to be printed. When it is not necessary to include voice data in the print image, or when an image without voice data is printed, naturally the encoded voice data is not printed and only the image is printed.

In this embodiment, the camera section A100
The printer built-in camera in which the printer unit B100 is integrated has been described. However, the camera unit A10
0 and the printer unit B100 may be separate devices and connected by the interface 210, and the same function can be realized.

FIG. 17 is a graph for explaining the wiping speed control in this embodiment. In the present embodiment, similar to the conventional wiping mechanism described with reference to FIG. 18, wiping is performed using the scanning operation of the carriage. 17A to 17E are the same as FIGS.
Corresponds to (e). The wiping load described with reference to FIG. 18 is shown by a dotted line in FIG. 17, the speed command value is shown by a thick solid line, and the actual scanning speed is shown by a thin solid line.

Further, in FIG. 17, (a) to (a) of FIG.
(C) is called a first area, and (c) to (e) are called a second area.

The target speed (Vw1) during wiping in this embodiment is 100 mm / sec. By controlling the speed command as indicated by the thick solid line in FIG. 17, the scanning speed during wiping (second region) is 100 which is the target speed.
mm / sec.

Specifically, first, the speed command is raised to 250 mm / sec (Vw3) before the wiping is started. As a result, the scanning speed is also about 250 mm / s.
It becomes ec. After that, the speed command is passed from Vw3 to Vw at the first deceleration inclination from a position slightly passing the scanning position of (a) (here, α in time) to the position of (c).
Lower to 2. Vw2 is faster than Vw1 and is 120 mm / sec in this embodiment. next,
The speed command is switched to the second deceleration slope from the position (c), and the speed command is lowered until it becomes Vw1. The second deceleration slope is gentler than the first deceleration slope. It is β in time from the position (c) until the speed command becomes Vw1.

By giving the above-described speed command to the scanning speed control system, the scanning speed after the start of the wiping can be maintained at the target speed of 100 mm / sec (Vw1). This speed control utilizes the inertial force of the carriage and its drive system.

At the position (b), the wiping load exceeds the torque generated by the miniaturized motor, so that deceleration (negative acceleration) occurs. Therefore, the scanning speed is set higher than the target speed (Vw1) in advance, and the speed command is lowered in accordance with the deceleration, so that the scanning speed at the position (c) where the wiping is started is close to the target speed Vw1. I am trying. Further, by switching from the first deceleration slope to the second deceleration slope before the speed command reaches the target speed Vw1, the scanning speed including the undershoot is maintained at almost the target speed Vw1. In FIG. 17, the undershoot is indicated by γ.

The second deceleration inclination is such that the scanning speed is maintained at the target speed Vw1 in accordance with the return from the undershoot. This is realized by adjusting β in FIG. As a result, the scanning speed is reduced to the target speed, and then the speed is stably maintained.

In order to realize the control of the scanning speed as described above, the above Vw1, Vw2, Vw3, α,
A parameter such as β may be adjusted according to the torque generated by the motor and the inertial force of the carriage and its drive system.

The speed command is applied to the target speed Vw with the second deceleration slope.
If the speed command is reduced to 1, then the speed command is changed to the target speed Vw.
Keep 1 Then, the speed command is started to be lowered slightly (here, δ in terms of time) from the position of (e). As a result, the influence of the rapid increase in speed caused by the rapid decrease in the wiping load at the position (e) is reduced.

In the present embodiment, the apparatus using the carriage scanning mechanism using the lead screw is shown as an example, but the present invention is not limited thereto and can be changed within the range not departing from the spirit of the present invention. is there. For example, a carriage scanning mechanism using a belt, a wire or the like may be used.

In the present embodiment, a closed loop carriage scanning control device using a DC motor as a drive source is shown as an example, but the present invention is not limited to this and does not violate the spirit of the present invention. The range can be changed. For example, open-loop control using a pulse motor or a hybrid motor may be used.

Further, in the present embodiment, as an example, the first deceleration slope and the second deceleration slope in the speed command are linear deceleration slopes, but the present invention is not limited to this, and the present invention is not limited to this. It can be changed without departing from the spirit of. For example, a curve such as a cubic function may be applied without any problem.

Further, in the present embodiment, as an example, the "lateral wiping" device for wiping the ejection port surface of the recording head by scanning the carriage with respect to the fixed wiper is shown. However, the present invention is not limited to this. It is not limited to. The present invention can be applied to any device as long as the wiper and the discharge port surface move at a relative speed. As another example of the wiping mechanism, one in which the wiper scans the stopped carriage and one in which the wiper rotates to perform the wiping can be considered. Even in that case, if the motor for driving the wiper is ineffective, the relative speed of the wiper and the carriage during wiping can be kept good by controlling the scanning speed or rotation speed of the wiper according to the gist of the present invention. .

The member for removing ink in this embodiment may be a rubber blade or a sponge-like member.

Further, in the present embodiment, an example in which a speed command having a two-step deceleration inclination is given when decelerating the scanning speed of the carriage from 250 mm / sec to 100 mm / sec is shown, but undershoot causes wiping. As long as it does not adversely affect the effect, the measurement command may be decelerated to the target speed of 100 mm / sec in one step. Further, a speed command having a deceleration gradient of three steps or more may be used.

[0120]

According to the present invention, before the removing member comes into contact with the discharge port surface, the removing member and the discharge port surface are relatively moved at a relative speed sufficiently higher than the speed suitable for removing the unwanted matter. Since the inertial force is small, it does not decelerate to an inappropriate speed even if the relative speed decreases when the removal member and the discharge port surface start to contact, and it is a good waste material because the inertial force is small. Can be removed. Therefore, the ultra-small recording head,
Even in an inkjet recording apparatus having a small inertial force, which is a combination of a microcarriage and a microdrive motor, it is possible to stably remove unnecessary substances. This makes it possible to provide an ultra-small inkjet recording device that can be built in, for example, a digital camera while maintaining high printing quality.

Further, since the control device controls so as to reduce the relative speed between the removing member and the discharge port surface in accordance with the deceleration caused by the contact between the removing member and the discharge port surface, the removing member and the discharge port surface are controlled. The relative speed of can be smoothly approached to the first speed suitable for removing the unwanted matter, and the unwanted matter can be favorably removed over the entire discharge port surface.

Further, since the relative speed between the removing member and the discharge port surface is gently reduced, overshoot and undershoot are reduced, and the control device can control the relative speed almost in accordance with the speed command. Unwanted substances can be stably and satisfactorily removed over the entire outlet surface.

Further, the relative speed between the removing member and the discharge port surface is determined by the command from the control device and the undershoot.
Since the speed is controlled to, the relative speed is not reduced more than necessary by the undershoot after reaching the first speed, and stable removal of unnecessary substances is possible.

Further, since the relative speed between the removing member and the discharge port surface is maintained at the first speed when returning from the undershoot, overshoot does not occur and the relative speed quickly stabilizes at the first speed. Stable removal of unwanted substances.

Further, since the control device raises the relative speed to the sufficiently high second speed before the deformation process, when the inertial force loses the reaction force and the deceleration occurs, it is possible to remove the unnecessary substances. It is possible to approach a suitable first speed, and since the deceleration is relaxed when the speed is lowered to the third speed, it is possible to make the relative speed the first speed by undershooting.
Since the first speed is maintained when returning from the undershoot, the relative speed quickly stabilizes at the first speed.

Further, since the control device controls so as to reduce the relative speed in accordance with the deceleration due to the deceleration applied to the removing member in the deformation process, it is possible to smoothly approach the first speed suitable for removing the unwanted matter. You can
