03 is rotatably held by the arm 304A with respect to the cylinder 304.

As shown in FIG. 5, a cap spring 306 is installed between the cap holder 303 and the base 14 facing the cap holder 303. The cap spring 306 keeps the cap holder 303 always in the recording head cartridge 1.
It is biased to the side. Here, the cylinder 304 is the base 14
It is rotatably supported by the cylinder axis.

Therefore, the cylinder 304 and the cap 3
01, the rotational force is applied by the cap spring 306 centering on the cylinder axis. Cylinder 30
4 includes a cylinder control unit 30 as shown in FIGS.
4C is integrally formed, and the cylinder control unit 304
The tip of C contacts the cam portion 19A of the pump cam gear 19 rotatably held by the base 14.

Therefore, the rotation of the cylinder 304 is controlled by the cam controller 1 of the pump cam gear 19 via the cylinder controller 304C.
Will be controlled by 9A. That is, along the cam portion 19A of the pump cam gear 19, the cylinder control portion 30
By moving 4C up and down (in FIG. 4, operation in the direction perpendicular to the paper surface), the cap 301 can press or release the cap to the recording head cartridge 1 via the cylinder 304. .

The pump cam gear 19 and the drive transmission portion held by the base 14 are provided at the right end of the base 14 avoiding the paper path (paper passage), and the pump cam gear 19 is press-fitted into the paper feed roller 6 by a press-fit shaft. Wearing LF gear 1

When the carrier 2 does not perform the clutch operation, the pump cam gear 19 has a partially toothless portion 19B.
Therefore, the transmission of the LF gear 18 is cut off and the drive is not transmitted to the pump cam gear 19.

When the pump cam gear 19 is rotated by driving the paper feed motor 23 after performing the clutch operation by the carrier 2 in FIG. 6, the piston shaft 305 and the cap 30 due to the rotation of the pump cam gear 19 are rotated.
The operation of No. 1 is shown in a chart.

The horizontal axis is the rotation angle of the pump cam gear 19, and the operation chart of the cap 301 is shown in the upper direction in the capping direction.
In the chart of the piston shaft 305, the upward direction is the negative pressure generation direction. The discharge port surface position indicated by the horizontal axis shows the relationship of the discharge port surface with respect to the cap 301, and when the upper surface of the cap 301 touches here, the capping operation is completed,
A portion indicated by a dotted line is an overstroke portion of the cap 301. That is, it shows the operation of the cap 301 when the recording head cartridge 1 is not mounted.

As can be seen from this chart, as the pump cam gear 19 rotates, the state changes from the capping-released state to the capping state, and at the same time, negative pressure is generated. Therefore, the ink can be sucked out from the recording nozzles of the recording head cartridge 1. The pump cam gear 19
Is configured to return to the original position by reversing after going to the right end shown in the chart.

As described above, in the pump mechanism portion, the cap 301 is pressed against the recording head cartridge 1 by being held by the base 14 and by interposing the cap spring 306 between the base 14 and the cap holder 303.

Therefore, the recording head cartridge 1 is capped at the time of non-recording to prevent the nozzle from drying, and at the time of ejection failure due to bubbles generated in the nozzle or dust adhering to the nozzle portion, the pump portion is operated to cause the nozzle portion of the recording head cartridge 1 to operate. By ejecting more ink, it is possible to normalize the ejection.

The cap 30 is provided by the pump mechanism section described above.
The ink sucked from the recording head cartridge 1 via 1 is treated as waste ink. The waste ink enters the cylinder 304 and is discharged from the cylinder end 304D by the movement of a piston (not shown). Cylinder end 30
4D is inserted in the base 14 and is rotatably held by the base 14. Cylinder end 304D
A cylinder absorber 311 is inserted in the. The cylinder absorber 311 is made of foamed sponge, and a material having a good ink transfer property is selected. Ie cylinder 304

Is fixedly supported by the blade holder 308 on the lower side and has a free end on the upper side. The upper end portion of the blade 302 is configured to have a length that can contact the ejection opening surface of the recording head cartridge 1 when the recording head cartridge 1 passes by the drive of the carrier motor 10. Therefore, when the ejection port surface of the recording head cartridge 1 is passed over the blade 302, the upper end portion of the blade 302 comes into contact with the ejection port surface, and the upper end portion of the blade 302 flexes the surface of the ejection port surface. You will be squeezed.

By this operation, foreign matter such as dust adhering to the vicinity of the nozzle on the ejection port surface is removed to always perform normal recording (wiping operation).

Further, the blade holder 308 moves to the direction away from the discharge port surface while tilting in the direction away from the cap 301, and retracts to the position where it does not touch the discharge port surface. It is rotatably supported.

In FIG. 1, the carrier 2 is moved to the right, and the carrier 2 is configured to perform the retracting operation by tilting the blade release lever 309 to the right.

In 08, the retracting operation is released, and it is configured to return to a position where it can contact the discharge port surface.

FIG. 7 shows a chart for explaining the operation.

When the carrier 2 moves to the right in the above figure,
The figure below shows the carrier 2 moving from the right end to the left. In each case, the vertical axis is the height of the tip of the blade 302,
As it goes up, it is the direction in which it comes into contact with the discharge port surface. The horizontal axis indicates the position of the carrier 2.

The horizontal line marked as the discharge port surface position in FIG. 7 shows the position of the discharge port surface with respect to the blade 302, and when the tip of the blade 302 is above the line (indicated by the dotted line in the figure). In the range), the tip of the blade 302 flexes in the bending direction by that amount and performs a wiping operation. That is, the dotted line in the figure indicates the blade 3 that is bent when it comes into contact with the ejection port surface when the recording head cartridge 1 is installed.
The movement of the tip of 02 is shown.

In the above figure, when the carrier 2 moves to the right, the contact between the blade 302 and the discharge port surface starts at point A (that is, the wiping operation indicated by the dotted line in the figure), and the carrier 2 is further moved. At point B, the carrier 2 begins to tilt the blade release lever, so that the blade 302
Ends the wiping operation after being separated from the ejection port surface.

In the lower diagram, the carrier 2 is moved from the right end to the left. At the point C, the protrusion (not shown) of the carrier 2 tilts the blade lever 310 to the right, so that the tip of the blade 302 is moved to the initial position. It returns to the position and prepares for the next wiping operation.

With this configuration, the carrier 2 is moved to the right end in FIG. 1 to perform the wiping operation of the ejection port surface of the recording head cartridge 1. Therefore, this operation is performed when necessary. Then, it becomes possible to obtain a normal record.

After turning on the ED 206, the image signal is read via the scanner driver unit 513 while driving the carrier motor 10.

Here, the drive speed of the carrier motor 10 can be changed depending on the original reading mode of the scanner head 200. The mode is a combination of the reading resolution and the gradation of each reading value.
1 has a resolution of 360 dpi in the main scanning direction, the resolution of the sensor 202 of the scanner head 200 is 360 dpi in the sub-scanning direction, and an output of 64 gradations can be obtained. Therefore, for example, 360 dpi in the main scanning direction and 360 dpi in the sub-scanning direction.
From 64 gradation reading to 90 dpi in the main scanning direction,
Fax with 2 gradations in the sub-scanning direction of 90 dpi and fax with the main scanning direction of 200 dpi.
There is also a mode that considers the consistency with. Main scanning direction 360
In a mode with a large amount of data, such as a reading of 64 gradations in a dpi of 360 dpi in the sub-scanning direction, it takes time to process and transfer data, so the carrier drive speed is slowed down to 90 dpi in the main scanning direction and 90 dpi in the sub-scanning direction. The carrier driving speed can be increased when reading gradations.

When the reading of one line is completed, the paper feed motor 23 conveys one line to read the next line. Such an operation is repeated until the original is finished. The standby position of the carrier 2 when the scanner head 200 is attached to the carrier 2 does not have to be the same as the position when the recording head cartridge 1 is attached, and the reading surface 200b of the scanner head 200 is used for maintenance of the recording head cartridge 1. If the shape avoids the recovery unit 300 (the blade 302 or the cap 301) that performs the operation, the idle position is moved to increase the traveling stability of the carrier 2 by moving the standby position to the recovery unit 300 side. It may be used as a section. In this embodiment, the line segment 214 in FIG. 2 is the stop position of the carrier 2 on which the scanner head 200 is mounted.

Further, as shown in FIG. 1, a white reference 9 having a reference reflectance of reflection density of 0.1 or less is provided for the purpose of determining the level of the image signal, and the CPU 502 is a carrier equipped with the scanner head 200. After moving 2 to above the white reference 9, the LED 206 is turned on and the signal from the sensor 202 is read and used as the reference of the image signal. Also, CPU5
The timing at which 02 performs the above-described white reference check may be immediately after the scanner head 200 is mounted, immediately before reading the original, or during the reading of the original.

As described above, the recording apparatus of this embodiment is capable of recording on the recording paper 22 by the recording head cartridge 1 and reading an original by the scanner head 200. In the case of the paper 22, the manuscript is also included, except for the case where only the description about the recording is given.

If there is the recording paper 22 between the two, the recording paper 22 can be sent to the paper feed port of the recording apparatus.

The automatic paper feed motor 101 is provided with a motor pinion (not shown) at the tip of the output shaft, and is engaged with the claw 115a of the gear box 115 for accommodating the reduction gear train 103 composed of a plurality of two-stage gear trains. And is fixed. The automatic paper feed motor 101 is a pulse motor, which is a two-phase excitation type.
It is driven in a bipolar manner and makes one lap in 20 steps. Also,
The total gear ratio for deceleration from the automatic paper feed motor 101 to the drive gear 116 is about 1:74.

Next, the detection of the initial position (home position) of the automatic paper feeder 100 will be described. As shown in FIGS. 12 and 13D, an initial position detecting cam 116d is provided at a position of the drive gear mechanism that faces the detecting portion 102a of the sheet feeding initial sensor 102. The initial position detecting cam 116d is separated from the detecting portion 102a of the paper feeding initial sensor 102 at the home position once per revolution to output an on signal from the paper feeding initial sensor 102, and the initial position detecting cam 116d. Is configured to output an off signal from the paper feed initial sensor 102 by pressing the detection unit 102a. The initial position (home position) of the automatic paper feeding unit 100 is detected based on the on (off) signal from the paper feeding initial sensor 102.

A series of operations of the automatic sheet feeder 100 having the above-mentioned structure will be described with reference to FIGS. FIG.
17 to 17 are diagrams showing the operation of the portion corresponding to FIG. 13 over time, and FIG. 18 is a timing chart of each element.

The operation of the automatic paper feed unit 100 includes an automatic paper feed mode in which the recording papers 22 stacked in the paper feed guide unit 14a are separated and fed one by one, and an operator himself / herself inserts the recording papers into the paper feed port. There is a manual feed mode in which 22 is directly supplied. First, the automatic paper feed mode will be described.

<Automatic Paper Feeding Mode> FIG.
2 shows the state of the home position before 2 is loaded. At this time, each element of the automatic paper feeder 100 is in the state of (1) in FIG. (A) The paper stopper 104 is in the paper stopper hole 14b of the paper feed guide portion 14a of the base 14. Therefore, the leading edge of the recording paper 22 stacked on the paper feed guide portion 14a is positioned by the paper stopper 104. (B) The separation roller 105 is in the inoperative position because the cam maximum radius portion 113c of the cam portion 113b of the separation roller shaft 113 is in contact with the cam receiving portion 111a of the separation roller shaft. (C) In the auxiliary roller 108, the cam maximum radius portion 114c of the cam portion 114b of the auxiliary roller shaft 114 is in contact with the cam receiving portion 111b of the auxiliary roller shaft, and the separation roller 105
It is in the inoperative position as well. (D) The cam 116d for detecting the initial position of the drive gear mechanism is the detection unit 10 of the paper feed initial sensor 102.
It is separated from 2a. As a result, the paper feed initial sensor 102 outputs an on signal.

FIG. 14 shows a state in which the automatic feed motor 101 has started to rotate and the drive gear mechanism has rotated about 43 ° from the home position. This position is also the manual feed mode position. At this time, each element of the automatic paper feeder 100 is in the state of (2) in FIG. (A) The paper stopper 104 comes out of the paper stopper hole 14b of the paper feed guide portion 14a of the base 14 and becomes an inoperative position, and a supply path is formed between the paper stopper 104 and the paper feed guide portion 14a. (B) The separation roller 105 is still in the inoperative position. (C) The spare roller 108 is also in the inoperative position. (D) The cam 116d for detecting the initial position of the drive gear mechanism rotates, and the detection unit 102a of the paper feed initial sensor 102 is pushed in. As a result, the feed initial sensor 102 outputs an off signal.

In FIG. 15, the automatic paper feed motor 101 further rotates and the drive gear mechanism moves from the home position to about 9 degrees.
It is a state rotated by 3 °. At this time, the automatic paper feeding unit 100
18 is in the state of (3) in FIG. (A) The paper stopper 104 is in the inoperative position as described above. (B) The separation roller 105 comes into contact with the separation sheet 112 on the paper feed guide portion 14a and comes to the working position prior to the auxiliary roller 108. (C) The spare roller 108 is still in the inoperative position,
The recording paper 22 is not yet fed and is in the initial position. The separation roller 105 is first set to the working position because the spare roller 1
This is to prevent the double feeding of the recording sheets 22 by confirming the separation mechanism of the separating unit before the feeding of the recording sheets 22 by 05 occurs. (D) The cam 116d for detecting the initial position of the drive gear mechanism is the same as that described above for the paper feed initial sensor 102.
The sheet feeding initial sensor 102 outputs an off signal.

In FIG. 16, the automatic paper feed motor 101 further rotates, and the drive gear mechanism moves from the home position to about 1 degree.
It is in a state of being rotated by 29 °. At this time, the automatic paper feeding unit 10
Each element of 0 is in the state of (4) in FIG. (A) The paper stopper 104 is in the inoperative position as described above. (B) The separation roller 105 is in the working position as described above. (C) The auxiliary roller 108 is in the operating position, and the feeding of the recording paper 22 is started. When there are a plurality of recording sheets 22 on the separation sheet 112, the coefficient of friction between the auxiliary roller 108 and the recording sheets 22 is larger than the coefficient of friction between the recording sheets 22, so only the uppermost recording sheet 22 is conveyed. Begin to. The coefficient of friction between the separation sheet 112 and the recording paper 22 is
Since the friction coefficient between the recording papers 22 is still larger, the plural recording papers 22 are not conveyed at one time. Here, the friction coefficient between the auxiliary roller 108 and the recording sheet 22 .mu.y The friction coefficient between the recording sheets 22 ... .mu.k The friction coefficient between the recording sheet 22 and the separation sheet 112 ... .. .mu.mb, the relation is .mu.y>.mu.k> .mu.mb. (D) The cam 116d for detecting the initial position of the drive gear mechanism is the same as that described above for the paper feed initial sensor 102.
The sheet feeding initial sensor 102 outputs an off signal.

In FIG. 17, the automatic paper feed motor 101 further rotates, and the drive gear mechanism moves from the home position to about 2 degrees.
It is a state rotated by 33 °. At this time, the automatic paper feeding unit 10
Each element of 0 is in the state of (5) in FIG. (A) The paper stopper 104 is in the inoperative position as described above. (B) The separation roller 105 is in the operating position as described above, and the recording paper 22 passes over the separation section and the separation roller 10
The sheet is sent to the sheet feeding port of the recording apparatus by the number 5. (C) The auxiliary roller 108 begins to be in the inoperative position. The reason why the preliminary roller 108 is first set to the inoperative position is the same as the reason described in the state of FIG.
Before the separation mechanism of the separation unit is released by setting 08 in the inactive position first, the recording paper 22 by the auxiliary roller 108 is released.
This is because the conveyance is stopped and the double feeding of the recording paper 22 is prevented. (D) The cam 116d for detecting the initial position of the drive gear mechanism is the same as that described above for the paper feed initial sensor 102.
The sheet feeding initial sensor 102 outputs an off signal.

Thereafter, the state returns to the state shown in FIG. 13, and one cycle of the operation is completed. In the device of the present invention, the diameters of the separation roller 105 and the auxiliary roller 108 are small for downsizing. Therefore, since the recording paper 22 does not reach the paper feed port in the operation of one cycle, the recording paper 22 is normally fed in four cycles.

Further, the paper sensor 25 (see FIG. 1) provided in the vicinity of the paper feed port detects whether or not the recording paper 22 is normally conveyed toward the paper feed port, and FIG. If the presence of paper is detected at a position where the drive gear mechanism rotates about 115 ° from the initial position, which is the state between FIG. 15 and FIG. 15, the automatic paper feed motor 101 is driven for another 2 cycles + 78 °, and the automatic paper feed is started from there. The paper feed mechanism of the recording apparatus is activated in cooperation with the unit 100.

This is for aligning the leading edge of the recording paper 22 (taking out the resist), and when the recording paper 22 is conveyed while being pushed in by the automatic paper feeder 100, the recording paper 22 to the recording device is conveyed. There is also the effect of improving the bite of. At this time, the feeding speed in the automatic paper feeding unit 100 is
It is set almost the same as the recording device side. Note that, depending on the type of the recording paper 22, the recording paper 22 may not be fed to the position of the paper sensor 25 even in the second cycle.
It will be detected by.

After the recording paper 22 is fed to the recording apparatus side, the automatic paper feeder 100 returns to the initial state shown in FIG.

<Manual Feed Mode> The automatic paper feed motor 101 is rotated and stopped to the position shown in FIG. Since the separation roller 105, the auxiliary roller 108, and the paper stopper 104 are in the non-acting position, the operator can directly insert a desired sheet into the paper feed port of the recording apparatus beyond the paper stopper.

This mode is used for, for example, thick sheets that cannot be fed and conveyed by the automatic sheet feeder.

The operation control sequence of the automatic sheet feeder in the above-mentioned configuration will be described with reference to the flow charts of FIGS.

FIG. 33 is a flow chart for explaining the processing of the initial operation of the automatic paper feeder when the power of the recording apparatus or the information processing apparatus is on.

When the initials of the automatic paper feeder are started,
In S201, a value corresponding to A = 82 steps is set and stored as an initial value in the initial step storage area in the RAM. This value is the number of steps to drive the automatic paper feed motor 101 from the off → on edge of the paper feed initial sensor 102 to the home position.

In the next step S202, it is determined whether or not the paper feed initial sensor 102 is turned on.

At this time, if the paper feed initial sensor is on, the automatic paper feed motor is driven for 300 steps in S203 in order to turn off the paper feed initial sensor, and then the process proceeds to the next S204. To do.

If the paper feed initial sensor is off, the process directly proceeds to the next step S204.

In the next S204, the automatic paper feeding motor 101
In step S205, the automatic feed motor is driven by the number of steps corresponding to the value A stored in the initial step storage area after the off → on edge of the paper feed initial sensor 102 is detected. After that, the automatic paper feed motor is stopped, and the process proceeds to the next S206.

At the next step S206, it is determined whether the automatic paper feed mode or the manual feed mode is designated. In the automatic paper feed mode, the initials of the automatic paper feed unit are completed.

If it is determined in S206 that the manual feed mode is set, the process proceeds to S207.

In step S207, the automatic paper feed motor is driven 176 steps to change the state of each component in the automatic paper feed unit to the position corresponding to the manual feed mode, and the automatic paper feed motor is stopped.
The initials of the automatic paper feeder are completed.

Next, FIG. 34 is a flow chart for explaining the processing of the operation of the automatic paper feed section until the drive of the paper feed motor in the automatic paper feed operation is started.

When a sheet feeding command is given, S22
In 1, the normal feeding drive of the automatic sheet feeding motor is started, and the automatic sheet feeding is started.

At the next step S222, N is set in the rotation number storage area in the RAM as an initial value for determining how many rotations the separation roller and the auxiliary roller have made after the automatic sheet feeding operation is started. = 1 is set, and in the following S223, it is determined whether or not it is the first rotation after the various rollers start the automatic paper feeding operation.

If it is determined in S223 that this is the first rotation, the flow shifts to S228. Since the area in which the paper feed initial sensor is turned on is measured during the first rotation, the paper feed initial sensor is turned off from the position where the automatic paper feed motor is driven 1300 steps from the home position of the automatic paper feed unit in S228. Detection of on edge is started.

Then, in S229, the measurement from the off → on edge to the on → off edge of the sheet feeding initial sensor is performed, and in the subsequent S230, the value from the off → on edge to the on → off edge of the sheet feeding initial sensor. After storing half of that in the initial step storage area, the process proceeds to S231.

In S231, the content of the rotation number storage area is changed to 2 in order to prepare for the decision to start driving for the second rotation.

In the following S223, it is judged again whether or not the driving of the various rollers is the first rotation, but this time it is the second rotation, so it is judged that it is not the first rotation, and S224. Transition to.

In S224, in the second rotation driving, the paper sensor 25 is detected to be ON at the timing when the 470-step automatic paper feeding motor is driven from the home position.

When it is determined in S225 that the paper sensor is on, the process proceeds to S226, and when the automatic paper feed motor is driven by 3261 steps, the drive of the paper feed motor is started.

In S227, the automatic paper feeding motor is driven from the off → on edge of the paper feeding initial sensor up to the value stored in the initial step storage area, and then stopped to complete the paper feeding operation. Becomes

If it is determined in S225 that the paper sensor is off, the process proceeds to S232.

In S232, it is determined whether or not the various rollers have been driven four times.

At the time point described above, the rotations of the various rollers are two rotations, so the process proceeds to S231 to prepare for the determination that the drive is the third rotation, and the third rotation is continuously driven. To do.

Then, in S223, it is judged again whether or not the drive is the first rotation. However, since the drive is the third rotation this time, the process proceeds to S224, and in the third drive,
At the place where the 470-step automatic paper feed motor is driven from the home position, the paper sensor is detected to be on.

When it is determined in S225 that the paper sensor is on, the process proceeds to S226, and the same control as described above is performed as S226 → S227.

Further, in S225, the paper sensor is turned on.
If it is determined to be ff, the same control as in S232 described above is performed, and at the time point described above, the rotation of each type of roller is three revolutions, so the process proceeds to S231, and at the fourth drive. Preparation is made for the judgment that there is, and the fourth rotation is continuously driven.

Next, in S223, it is judged again whether or not the drive is the first rotation. However, since this time the drive is the fourth rotation, the flow shifts to S224, and in the drive of the fourth rotation, 470 from the home position. When the step automatic paper feeding motor is driven, the on detection of the paper sensor is performed again.

When it is determined in S225 that the paper sensor is on, the process proceeds to S226, and the same control as that described above is performed from S226 to S227.

If it is determined in S225 that the paper sensor is off, the process proceeds to S232.

This time, since the paper sensor has not been turned on even in the drive section for the fourth rotation, S23
3, the error message is displayed on the display, and the user is informed by the buzzer that the user is in an abnormal state. Then, the process proceeds to S227, and the same control as S227 described above is performed to end the process. .

Next, FIG. 35 is a flow chart for explaining the processing of the operation of the automatic paper feed section when switching from the automatic paper feed mode to the manual feed mode. First, in step S270, it is determined whether or not there is an instruction from the information processing apparatus, which is the main body, to switch from the automatic sheet feeding mode to the manual sheet feeding mode. If there is an instruction, the process proceeds to step S271 to turn on the automatic sheet feeding motor 176. The step forward drive is performed, and the process of switching from the automatic paper feed mode to the manual feed mode is completed. If there is no command from the information processing apparatus, which is the main body, in S270 to switch from the automatic paper feed mode to the manual feed mode, the process ends.

FIG. 36 is a flow chart for explaining the processing of the operation of the automatic paper feed section when switching from the manual feed mode to the automatic paper feed mode.

First, in S280, it is determined whether or not there is an instruction from the information processing apparatus, which is the main body, to switch from the manual feed mode to the automatic paper feed mode. If there is an instruction, the process proceeds to S281 and the automatic paper feed is performed. The motor is reversely driven by 176 steps to complete the switching process from the manual feed mode to the automatic paper feed mode. Further, in S280, if there is no command from the information processing apparatus which is the main body to switch from the manual feed mode to the automatic paper feed mode, the processing is ended as it is.

Next, the manual sheet feeding process will be described with reference to FIG.

First, the operator passes the leading edge of the recording sheet under the automatic sheet feeding section and inserts it toward the sheet feeding port of the printer main body so that the leading edge of the recording sheet hits the sheet feeding roller and the pinch roller. , And the manual paper feeding process starts. First, in S250, it is determined whether or not there is a sheet feed command by key input or the like. If there is a sheet feed command, the process proceeds to the next S251.

In S251, the paper sensor is turned on.
If it is determined to be true, the process proceeds to S252, and the normal rotation drive of the automatic paper feed motor is started. And the next S25
In No. 3, when the automatic paper feed motor is driven by 612 steps, the drive of the paper feed motor is started, and the leading edge of the sheet is fed to the paper feed roller.

Further, in the subsequent S254, the automatic paper feed motor operates from the off → on edge of the paper feed initial sensor to (value A stored in the initial step storage area).
After driving for +176) steps, the operation is stopped and the manual paper feeding operation is completed. In S250, if there is no sheet feeding command by key input or the like, the process returns to S25.
It returns to 0 and waits for a paper feed command.

Furthermore, in S251, when it is determined that the paper sensor is off, the process proceeds to S255, the error process is performed, and the process is terminated.

Further, FIG. 19 shows a state of the information processing apparatus 400 when the display section 403 is in a displayable state and the keyboard section 402 is in an operable state. Further, in FIG. 20, the display unit 403 which also serves as a protective cover of the main body of the information processing apparatus 400 is closed and put in the stored state, and the printer unit 40
1 shows a state in which the printer cover 407 is opened to operate 1.

As shown in FIG. 22, the printer unit 401
Is incorporated, for example, in the rearmost part of the information processing device 400, but its mounting direction is such that the automatic paper feeding unit 100 is on the keyboard unit 402 side and the paper ejection roller 15 is on the rear end side of the information processing device 400. It is located in. That is,
The conveyance direction of the recording sheet is a direction in which the recording sheet is inserted from the keyboard side of the information processing apparatus 400 and discharged toward the rear end side of the housing. Further, the paper passing path passes through a gap between the lower surface of the keyboard unit 402 and the upper surface of the housing of the information processing device 400,
It is configured to reach the printer unit 401.

FIG. 21 shows a state in which the recording paper 22 is set on the information processing device 400. The keyboard portion shown in FIG. 19 has a hinge (not shown) at its rear end, that is, on the side close to the display portion 403, and is rotatable around the hinge. When the normal keyboard portion 402 is used, the state shown in FIG. 19 is used. When the recording paper 22 is set, the front end of the keyboard portion 402 is lifted and rotated as shown in FIG. 21 to facilitate the setting of the recording paper 22. Can be done. At this time, it is also possible to fix the keyboard portion 402 in the released state by a stopper (not shown).

After the recording paper 22 is set, it is possible to perform the recording operation with the keyboard portion 402 left as it is, or to perform the recording operation by closing the keyboard portion 402 and returning to the state of FIG. It is possible. In order to perform the recording operation in the latter state, even if a plurality of recording sheets are stacked between the lower surface of the keyboard unit 402 and the upper surface of the housing of the information processing apparatus 400, the movement of the recording sheets 22 is not hindered. Sufficient clearance is secured.

Further, the recording paper 22 stacking section on the upper surface of the housing of the information processing apparatus 400 is provided with a guide member so that the recording papers can always be stacked at a predetermined position. In the case of the information processing apparatus, since the left side of the recording sheet is used as the reference position during the recording operation, the recording sheet 22 is abutted against the left sheet guide 408 when the recording sheet is set, and further, the recording sheet width is set. By moving the right paper guide 409 which is movable in the width direction of the recording paper in accordance with the width of the recording paper, it is possible to stably convey the recording paper.

Next, the procedure performed by the operator when it is necessary to operate the printer unit 401 from the outside will be described.

The operation performed by the operator with respect to the printer unit 401 is, firstly, the recording head cartridge 1, the ink tank 8 and the scanner head 20 mounted on the carrier 2.
When removing or attaching 0, secondly, when cleaning the white reference 9 provided on the base 14 when it is contaminated for some reason, thirdly, the recording paper 22 is jammed for some reason. , Recording paper 22
When the ink is left in the printer unit 401, it is removed. Fourthly, when the recording ink is scattered to the outside of the area where the recording paper 22 exists for some reason and the base 14 is contaminated, it is cleaned. , Etc. are possible.

In the first case, when the operator operates the exchange key (not shown), the carrier 2 is in the exchange position (the carrier position in the enlarged view surrounded by the one-dot chain line in FIG. 20) by the means of the flowchart described later. Move to. In the exchange position, the carrier 2 is located in the printer opening 406 of the housing of the information processing device 400, and the printer opening 406 in the exchange position is shaped so that the operator can directly touch the carrier 2 with his / her hand. Has become. As a result, the operator can attach and detach the recording head cartridge 1 and the like from the carrier through the printer opening 406.

On the contrary, when the carrier 2 is at the home position, it is not preferable to replace the recording head cartridge 1 or the like because the vicinity of the ink ejection port of the recording head cartridge 1 may be damaged. Therefore, at the home position of the carrier 2, the printer opening 406 has a closed shape so that the operator cannot directly touch the carrier 2.

In the second case, the operator operates when the carrier 2 is at the home position. Since the white reference 9 of the printer unit 401 of the present embodiment is attached in the vicinity of the exchange position on the opposite side of the home position in the scanning range of the carrier 2, the printer opening 406 is provided when the carrier 2 is in the home position. Operator is white standard 9
It is shaped so that you can touch it.

In the case of this embodiment, since the exchange position is near the place where the white reference 9 is attached, the space where the operator puts his / her finger is shared with the printer opening when the carrier is operated in the first case. Therefore, it is not necessary to enlarge the printer opening 406 unnecessarily, and
0 It is possible to prevent the rigidity of the housing from decreasing.

In the third case, and in the fourth case, the second
The operation can be performed while the carrier 2 is at the home position as in the case of. Carrier 2 as mentioned above
Since the printer opening 406 near the home position of the recording sheet 22 is blocked, the recording sheet 22 and the entire recordable range of the base 14 cannot be touched, but most of the recording sheet 22 can be touched. It is possible to clean the jam and clean the base 14. Since the opening in this case does not need to be as wide as in the first and second cases, the opening can be made narrower than the printer opening at the carrier exchange position, and the information processing apparatus 400 It is possible to prevent the rigidity of the housing from lowering.

Next, of the operation of the information processing apparatus using the recording apparatus of this embodiment, matters related to the recording operation will be described with reference to a block diagram of an electric circuit and a software flowchart.

5, a sensor detection unit for detecting the output of a sensor such as the paper feed initial sensor 102 is shown. Further, reference numeral 404
Is an external storage device such as an FDD, HDD, or RAM card, and reference numeral 405 is an external interface for communicating with another information processing device or directly connecting to an internal bus to control peripheral devices. ing. Although not included in the block diagram of FIG. 23, there is another power supply unit for supplying power to the above electric circuit, which includes, for example, a rechargeable battery, a disposable dry battery, or an information processing unit. There is a converter for AC power supply when the apparatus main body is fixed and used.

Recording is performed on the recording paper 22 by the recording device section with the above-described electric circuit configuration. The outline of the recording operation control sequence will be described below with reference to the flowcharts of FIG.

FIG. 24 is a flow chart for explaining the processing when the power of the recording apparatus or the information processing apparatus is turned on and off. S1 is in the power-off state, and the timer 50
Functions other than the operation of FIG. 5 (FIG. 23) are stopped.
The operation is started from the power-off state by a power-on signal, that is, the power switch is turned on. In the recording apparatus, the power-on process of S2 is first executed. When S2 ends, the process next proceeds to S3 and the power is turned on.
The recording operation and the like are performed in the power-on state.
When a power-off signal is detected in the power-on state, the process proceeds to S4 and power-off processing is executed. When S4 ends, the process proceeds to S1 and the power is turned off. Therefore, when the power is turned on and off, a predetermined process is performed to turn the power on and off. When the pause signal is detected in the state of S3, the process proceeds to S5 and the pause process is executed. The pause signal means, for example, when the display unit 403 shown in FIG.
A means for detecting this when the user performs an action such as when the user is operating the device but not when the device is operating, such as when the device is folded on top of the two or when the battery is replaced. For example, it is a signal output by a sensor that detects opening / closing of the display unit 403, a sensor that detects attachment / detachment of a battery, or the like. Further, the temporary stop process is a process performed to prevent damage or failure of the device when the device is used differently from the basic use, and will be described in detail later. When the temporary stop process ends in S5, the process proceeds to S6, and the temporary stop state is set. In the suspended state, the functions other than the necessary parts are stopped or the power is turned off. When the temporary stop release signal is detected in the temporary stop state, the process proceeds to S7 and the temporary stop release processing is performed. The temporary stop release signal is a signal paired with the temporary stop signal, for example, when the display unit 403 changes from a closed state to an open state, or when the battery is removed from the attached state. Etc. is a signal indicating that the device has returned to the operable state. Further, the temporary stop release process is a process for returning to the state before the temporary stop, and the details will be described later. As a result, even when the user carelessly opens and closes the display unit 403 during operation of the device or attaches or detaches the battery, it is possible to return to the original state. S7
When the temporary stop release process is completed in step S3, the process returns to the power-on state in step S3. For the temporary stop signal, it may be possible to select whether or not to perform the temporary stop processing when the signal is detected. For example, when it is better to close the display unit 403 because the recording device handles paper during operation, the device setting should be selected so that the pause process is prohibited when the display unit 403 is opened and closed. can do.

FIG. 25 is a flow chart for explaining the S2 power-on process. First, in S11, automatic paper feed initialization is performed. Details are as described above.

Next, in S12, the recovery system, paper feed, and home position initialization are performed. Specifically, the paper feed motor 23 and the carrier motor 10 are initialized as a recovery system. After that, the paper feed motor 23 is driven to loosen the paper feed drive mechanism, so that the paper feed motor 23 is driven by a predetermined amount in the reverse direction and the forward direction, respectively. Next, home position initialization, that is, the position of the carrier 203 is determined. Specifically, after the carrier motor 10 is driven and the position at which the output of the home position sensor 26 is switched is set to the reference position of the carrier 203, the paper feed motor 23 and the carrier motor 10 are driven so that the ejection port of the recording head cartridge 1 is ejected. The cap 301 is closed by the cap 301.

Next, in S13, the time from the last ejection or suction of the recording head cartridge 1 by the timer 505 to the present is measured, and if the interval is a predetermined time n or more, the process proceeds to S14 to recover the recording head. The process is performed, and if it is the following, the process proceeds to S15. In S14, as the recovery processing of the recording head cartridge 1,
The ejection of the recording head cartridge 1 into the cap 301, the cleaning of the ejection opening of the recording head cartridge 1 by the blade 302, the suction of ink from the recording head cartridge 1 by the pump unit, and the like are performed. As a result of the recovery process in which the recording head cartridge 1 is left unused for a long period of time, it is possible to prevent ink ejection defects and the like due to an increase in viscosity due to evaporation of ink at the ejection port of the recording head cartridge 1. After S14, the process proceeds to S15 to check whether the paper sensor detects the presence of paper. If the paper is present, the process proceeds to S16. If the paper is not present, the process proceeds to S17.
In S16, the detected paper is discharged. That is, after the paper sensor 25 detects the absence of paper, the paper feed motor 23 is driven in the forward direction up to a predetermined amount. Next, in S17, the power-on process ends.

FIG. 26 is a flow chart for explaining the S4 power off process. First, in S21, it is checked whether the recording head cartridge 1 is in the capping state,
If it is not in the capping state, proceed to S22, and if it is in the capping state, proceed to S23. In S22, the carrier motor 10 and the paper feed motor 23 are driven to bring the recording head cartridge 1 into the capping state. Then S
At 23, the power of the recording apparatus is turned off and the function is stopped. In the present process, even when the recording head cartridge 1 is not in the capping state, that is, even when the power switch is turned off during the execution of recording, etc., the recording head cartridge 1 is reliably turned off after the capping state. This prevents occurrence of ejection failure due to an increase in viscosity due to evaporation of ink when the ejection opening portion 1 is exposed to the atmosphere.

FIG. 27 is a flow chart for explaining the S5 temporary stop processing. First, in S31, it is checked whether or not there is a process currently being executed, and if there is a process being executed, S32 is executed.
If not, go to S33. In S32, the process currently being executed is executed by a predetermined amount. Specifically, the process is executed until the recording of the line being executed is completed if the recording is being executed, and until the operation is completed if the paper feeding or the automatic paper feeding operation is being executed. If the paper discharge process is in progress, the process is immediately stopped.
Next, in S33, the current state is stored. That is, if there is any interrupted processing, the interrupted status, the status of the display unit 403 or the operation panel (not shown), the online status, the offline status, or the power saving mode for battery power supply, if any, is stored in the memory. . Next, in S34, the recording head cartridge 1 is put into the capping state.
If you are already capped, do nothing. Then S
Proceeding to step 35, the power of unnecessary portions is turned off in the temporary stop state. Next, the process proceeds to S36 and the S5 temporary stop process ends. Even if a pause signal is detected during printing in this process, the recording head cartridge 1 is reliably capped, and it is prevented that the recording head cartridge 1 is left uncapped and ejection failure occurs.

FIG. 28 is a flow chart for explaining the S7 temporary stop cancellation processing. First, in S41, a predetermined portion is initialized. Specifically, the position determination of the carrier 203, the rattling of the paper feed motor 23, the initial position setting of the automatic paper feed mechanism, and the like are performed in S11 and S12. Next, the process proceeds to S42, and the pre-pause state stored in S33 is checked. Next, the process proceeds to S43 and the process of returning to the state before the temporary stop is performed. Specifically, if there is any interrupted process, the process is completed and the states of the display unit 403 and the operation panel are restored. Next, the processing proceeds to S44, and the S7 temporary stop cancellation processing is ended. Therefore, even if the recording apparatus is temporarily suspended during processing, it is possible to continue the processing after the restoration and before the temporary stop.

FIG. 29 is a flow chart for explaining the processing in the S3 power-on state.

First, in S51, various errors are checked and error processing is performed. Specifically, for example, when there is no recording paper in the recording device, when the recording head cartridge 1 or the ink tank 8 is not attached, the ink tank 8
When there is no ink inside, when a paper jam is detected during the recording process, when the temperature of the recording head cartridge 1 is abnormally increased, when a scanning error of various motors is detected, etc. It is displayed on the panel and sounds a buzzer to warn. Next, in S52, key operation and command reception from the keyboard section 402, the operation panel, the external interface section 405, etc. are checked, and the corresponding processing is performed. Specifically, when the paper feed key is pressed, the paper is inserted, discharged, and the paper is fed by a predetermined amount according to the situation. When the online key is pressed, or when an online or offline command is received, the error status is checked and the online status and offline status are processed. If a command related to recording or the like is received, the corresponding process is performed. Furthermore, when a key input for replacing the recording head cartridge 1 or the ink tank 8 or the absence of ink in the ink tank 8 is detected, the carrier motor 10 is driven to move the carrier 203 to an easily replaceable position. After the transfer and the replacement are completed, the carrier motor 10 and the paper feed motor 23 are driven to move the recording head 201 to the cap 301, and the ink is sucked from the ejection port of the recording head cartridge 1 by the pump unit. Even when air is mixed in the ink flow path between the recording head cartridge 1 and the ink tank 8 when the ink tank 8 is replaced, the mixed air can be sucked out of the recording head cartridge 1 by suction of the ink. It is possible to prevent occurrence of ejection failure due to air inclusion in the cartridge 1. Then S5
Proceeding to step 3, recording processing is performed. Details will be described later. Then S5
If the power-off signal is checked and the power-off signal is detected, the process proceeds to the power-off process of S4 described above.
If not detected, the process returns to S51.

FIG. 30 is a flow chart for explaining the recording process in S53. First, in S61, it is checked whether or not a command for executing recording, for example, a paper feed command or the reception of data to be recorded is received. If there is a recording command, the process proceeds to S62, and if not, the process proceeds to S71 and the present process is terminated. In S62, the online state is checked. If it is in the online state, the process proceeds to S63, and if it is in the offline state, the process proceeds to S71 and the present process is terminated. In S63, it is checked whether the recording head cartridge 1 is mounted on the carrier 2. If installed, S6
If not, the process proceeds to S64. S64
Then, an error is displayed on the display unit 403 or the operation panel, or a buzzer sounds to warn. In S65, a process for starting recording is performed. Specifically, the temperature of the recording head cartridge 1 is adjusted by the heater in the recording head cartridge 1, and the ejection adjustment is performed by ejecting the recording head cartridge 1 out of the recording area.
The amount of deviation of the carrier motor 10 during forward / reverse scanning is measured by a home position sensor, and the deviation is corrected during bidirectional recording. Next, in S66, the paper feed is checked. When the paper is not inserted at the recording position in the automatic paper feed state, the automatic paper feed motor 101 is driven to feed the paper. Next, the process proceeds to S67 to execute recording in units of one line.
Specifically, the carrier motor 10 is driven and ink is ejected by the recording head cartridge 1 to perform recording,
When the recording of one line is completed, a predetermined amount of paper is fed and the process proceeds to S68. In S68, an error check is performed. If there is an error, the process proceeds to S70, and if there is no error, the process proceeds to S69. The error check is, for example, the detection of the lower end of the paper, the detection of the paper jam, the detection of the presence or absence of ink, the scanning error of various motors, etc. The detected error is processed in S51 described above. In S69, reception of a command indicating the end of recording, for example, a paper discharge command, is checked. If the recording is completed, the process proceeds to S70, and if the recording is not completed, the process returns to S67 to continue the recording. In S70, a recording end process is performed. Specifically, the paper is discharged, the recording head cartridge 1 is capped, and the like. Then S7
The process proceeds to 1 and the recording process in S53 is completed.

FIG. 31 is a flow chart for explaining the reading process in S53. First, in S81, it is checked whether or not there is a command for executing reading, for example, a reading start command. If there is a read command, S8
If not, the process proceeds to S92 to end this process. In S82, the online state is checked. If it is in the online state, the process proceeds to S83, and if it is in the offline state, the process proceeds to S92 and the present process is terminated. In S83, it is checked whether the scanner head 200 is attached to the carrier 2. If it is attached, the process proceeds to S85, and if not attached, the process proceeds to S84. In S84, an error is displayed on the display unit 403 or the operation panel, or a buzzer sounds to warn. In S85, processing for starting reading is performed. Specifically, the LED in the scanner head 200 is turned on, the amount of deviation of the carrier motor 10 during forward and reverse scanning is measured by a home position sensor, and the deviation is corrected during bidirectional recording.
Next, in S86, white reference correction processing is performed. Specifically, the carrier motor 10 is driven to move the reading unit of the scanner head 200 to the white reference 9 provided on the base 14, the white reference 9 is scanned to read the white level, and the white level is read according to the read level. It is stored as a correction value of the reading level that is read later. Next, in S87, the paper feeding is checked. When the paper is not inserted at the recording position in the automatic paper feed state, the automatic paper feed motor 101 is driven to feed the paper. Next, the process proceeds to S88, and reading is performed in units of one line. Specifically, the carrier motor 10 is driven and reading is performed by the scanner head 200,
When the reading of one line is completed, a predetermined amount of paper is fed and the process proceeds to S89. In S89, the error is checked, and if there is an error, the process proceeds to S91, and if there is no error, the process proceeds to S90. The error check is, for example, the detection of the lower end of the paper, the detection of the paper jam, the scanning error of various motors, and the like, and the detected error is processed in S51 described above. In S90, reception of a command indicating the end of reading, for example, a paper discharge command is checked. If the reading is completed, the process proceeds to S92. If the reading is not completed, the process returns to S88 to continue the reading. In S91, a recording end process is performed. Specifically, paper ejection, scanner head 2
The home position of 00 is moved. Next, the process proceeds to S92, and the reading process in S53 is completed.

FIG. 32 is a flow chart for explaining a device replacement process on the carrier 2 for performing the recording process and the reading process in S53. This means that when the recording device is in the power-on state of S3, for example, the keyboard unit 402
This process is started when an interruption is caused by an exchange key (not shown) in (1) or when an insufficient amount of ink is detected. First, in S101, it is determined whether or not there is an instruction to mount or replace the recording head cartridge 1, the ink tank 8, or the scanner head 200 on the carrier 2. If there is a replacement instruction, the process proceeds to S102, and if not, the process proceeds to S106 and the present process is terminated. In S102, when the carrier 2 is at the home position, the paper feed motor 23 is driven to release the fixing of the carrier 2, and the carrier motor 10 is driven to move the carrier 2 to a predetermined exchange position. In the replacement position, the operator selects the monochrome recording head cartridge 51 or the color recording head cartridge 5 among the recording head cartridges 1.
3 is replaced, the ink tank 8 that is out of ink is replaced, the scanner head 200 is replaced for reading, and so on. Then S1
In step 03, it is determined whether the exchange end key is pressed or a predetermined time has elapsed and there is an instruction to end the exchange. If there is an instruction to end replacement, proceed to S104,
If not, the process returns to S103 and waits for an instruction. S
At 104, the carrier motor 10 is driven to move the carrier 2 to the home position. Next, in S105, the type is detected according to the device such as the recording head cartridge 1 or the scanner head 200 newly mounted on the carrier 2, and the parameters necessary for using each device are stored in the RAM 503 via the interface unit 506.
Perform necessary processing such as setting to. At this time, the position of the home position is changed depending on whether the one mounted on the carrier 2 is the scanner head 200 or the recording head cartridge 1. In the case of the scanner head 200, the home position is changed from the carrier position when the recording head cartridge 1 is mounted. Also set to the position on the recovery part (blade or cap) side. In this embodiment, the line segment 214 shown in FIG. 2 is the reference stop position of the carrier 2 on which the scanner head 200 is mounted.
