2B is exposed to the outside from the side plate 27G, and the tube 820
The ink flowing out onto the top plate 260 is led to the drain tank 800. This protects the inside of the controller unit 200 from ink leakage from the recording system unit 100.

In this example, the tube 82B is connected to the tube 820, but it is also possible to guide all the ink collected by the cap 140 onto the top plate 280 and guide the ink from the hole 288 through the tube to the drain tank 800. By doing so, the configuration of the tube system can be made extremely simple.

3.4 Recovery system (1) Cap opening/closing mechanism FIGS. 28 and 28 show the closed and open states of the cap 140 with respect to the cap cover 150. Here, 141A and 141B indicate the vertical movement of the cap 140. The guide rail 142A is the cap 140
This is a holding member that holds the holder rotatably around a vertical axis and is slidable along the rail 141A. 143B is rail 1
This is a member that connects and separates the sliding member provided at 41B. Further, 825 is a waste ink reservoir provided below the cap 140, to which a tube 820 is connected.

According to this configuration, a sufficient work area is ensured during maintenance work of the cap 140, and such work becomes extremely easy. Further, according to this example, since the cap 140 is rotatable about the vertical axis, it is possible to prevent the nozzles of the head from being contaminated by color mixing of ink in the cap portion.

Further, in the figure, 145 is the back surface of the cap.

This rear surface 145 is made engageable with the cam surface 342B of the pinch roller side plate 342, and the cap 140 is moved downward when the pinch rollers 100 and 300 are connected while the pinch roller 330 remains open. to close the lower paper feed mechanism.

(2) Cap Cover FIGS. 30 and 31 are a perspective view showing an example of the configuration of the cap cover 150 and the cap 14, respectively.
FIG. cap cover 1
50 is given the habit of always moving toward the cap side by a spring 151. Moreover, 152 is a roller that can be engaged with a portion 149 on the front surface of the cap 140.

These rollers 152 and the portion 149 are disengaged when the cap 140 is in a position facing the cap cover 150, and the spring 151 moves the cover 150 toward the cap 140 to cover the cap 140. Become. Thereby, the cap 140 can be protected from dryness, dust, and the like.

Also, when the cap 140 is moved, the roller 152 is moved to the portion 1.
48 and the cover 150 retreats against the spring force, so the movement of the cap 140 is not obstructed by the cover 150.

(3) Capping of the head unit The capping process for the head unit 110 can be performed by the processing procedure described later with reference to FIG. In order to obtain an appropriate and reliable engagement state at the cap position, in this example, a recess 1 is provided on the front surface of the cap as shown in FIG.
46, and on the other hand, as shown in FIGS. 28 and 32, a convex portion 13El that can fit into this concave portion 146 is provided on the side of the heel 110, as shown in FIGS. Since the assembly 130 is given the habit of moving toward the cap, when the cap 140 faces the head unit 110 by the process described later, the protrusion 136 fits into the recess 146, and the cap 140 is prevented from moving in this position. The cap 1 is blocked and the head unit 110 is
40 can be accurately and reliably positioned, and appropriate recovery processing can be performed.

3.5 Recording head assembly FIG. 32 shows an example of the configuration of the recording head assembly 130. As shown in FIG. Protrusion 134. And a protrusion that can be fitted into the recess of the cap 140! Set up 3G, and 13
8 is a fan for backing up the suction of the recording paper P onto the platen 392 by the fan 390F.

This head assembly 130 is attached to a movable base shown in Figure 33.

3.6 Recording head assembly in recording unit 1
Support Structure 30 FIG. 33 shows the disassembled state of the support structure of the recording head assembly 130 in the recording system unit 100. 160 is a fixed base, and 170 is a movable base movably provided on the fixed base 1BO. be. A recording head assembly 130 is fixed on a movable table 170.

On the underside of the fixed base 160 is a motor for driving the movable base 170 (
A drive mechanism 180 including a pulse motor) is fixed. A screw is fixed to the tip of the motor shaft of the drive mechanism 180 via a universal joint, and a guide mechanism 181 that converts motor rotation into linear motion is coupled to this screw. This guide mechanism 181 protrudes upward from an opening 181 formed approximately in the center of the fixed base l60, and extends a portion of the guide mechanism 181 to the movable base 17.
Attach to the bottom of 0.

Therefore, the drive mechanism 1
80 moves the movable base 170.

The drive mechanism 18G is positioned and fixed to the fixed base 180, and the guide mechanism 181 is fixed to the movable base 170 so that the movable base 170 moves back and forth in a direction perpendicular to the recording surface (when set) in the paper feeding unit 300. Install.

On the upper surface of the fixed base 1130, there are guide rails in front and behind the opening 1131! 62 and 183 are fixed. The direction of this rail coincides with the direction of movement of the movable base 170. On the other hand, on the lower surface of the movable base 170, there are guide rollers 171 and 17 whose axes are perpendicular to the front and rear sides.
Install 2. The front guide roller 171 is located inside the idle rail 182, and the rear guide roller 172 is located inside the idle rail 182.
is located inside the rear guide rail 183, and therefore, the movable base 170 is regulated by these guide rails and guide rollers and moves on a predetermined path.

On the upper surface of the fixed base 160, the upper portion of a first roller 1B4 fixed to the lower surface thereof protrudes through an opening 185. The axis of this roller 1G4 coincides with the moving direction of the movable table 170. On the other hand, when the movable table moves forward (when moving forward to the recordable position), the first receiver is connected to the roller 1B.
The second support fixes a roller 173 to the lower surface of the movable base 170 so as to face the roller 173. The axis of this roller 173 is perpendicular to the axis of the first roller 184. Further, the width of the front guide rail 182 is approximately equal to the diameter of the surface side roller 171 at its front portion, and the width of the rear guide rail 183 is approximately equal to the diameter of the rear roller 172 at its rear portion.
approximately equal to the diameter of the rear roller 1 at its front part.
Therefore, when the movable platform moves forward, the front roller 171 is restrained and fixed by the front part of the front guide rail 182, and the backup roller 172
is located in front of the rear guide rail 183, so the movable base 170 becomes a swinging unit in a horizontal plane around the front roller 171. In addition, at this time, the first
The receiver is a roller 164 The second receiver on the movable table side is a roller 1
73 are placed thereon, the rocking motion can be performed more smoothly. Further, due to this swinging motion, the positioning operation of the front surface portion of the recording head assembly 130 fixed to the movable base 170 for positioning with respect to the reference plane on the paper feeding unit side of the recording head assembly 13G can be performed very easily and smoothly.

On the other hand, as shown in FIG. 34, a locking mechanism 183 is fixed to the lower surface of the fixed base 180 for fixing the movable base 170 to the fixed base 160 when the movable base is retreated.

The lock mechanism 183 includes a solenoid 184 and a lock lever 185 that is driven by the solenoid and rotates in a vertical plane. The lock lever 185 is a 0-mouth 7 clever lever that forms a groove 185A on the upper side of its rotating tip.
85 projects to the upper surface side of the fixing base 160 through an opening 18B formed in the fixing base 18G. Movable platform! A retaining pin 174 is fixed to the lower surface side of 70. This engagement pin 174
is positioned directly above the rotating tip of the lock lever 185 when the movable base 17G is retreated. Therefore, when the movable base 170vk is retracted, the solenoid 184
By operating the lock lever 185, the retaining pin on the movable table 170 side is engaged in the groove 185A at the rotating tip of the lock lever 185. As a result, the movable table 170 (1, therefore, the recording head assembly 130) is reliably fixed and supported by the fixed table 180 (for example, the recording head assembly 130 is reliably fixed to the recording head unit during transport of the m-load).

When the movable base 100 is connected to the recording head unit 100 and the paper feeding unit, the movable base 17 described above moves forward.
Due to the rocking effect of 0, the positioning protrusion 132 on the front surface of the recording head assembly 130 is
(paper feeding unit) 30G reliably contacts the reference surface 306B. Furthermore, in this state, another projection 134 for positioning on the front surface of the recording head assembly 130 has a
The platen 392 is pressed by the spring force, whereby the recording surface of the recording paper P regulated by the platen 392 is reliably positioned with respect to the nozzles of the assembly 130.

4. Configuration of control system Figure 35 is a block diagram showing the electrical configuration of the entire image forming apparatus to which the present invention is applied. In this figure, an IC is a host that sends image information to be recorded via an optical fiber. It's a computer.

MD is a modulator/demodulator that performs mutual conversion between optical signals and electrical signals.

CC is a communication controller that has the function of extracting only image data from a data signal obtained from the host computer HC and sending it to the image memories INN and INS.

MP is a main processor including a CPU, and performs various controls of the entire device.

MO is a mechanical controller that includes a CPU, and in addition to communicating with the head assembly mechanism described later, it also includes a pulse motor Ml for feeding the fan fault recording paper and a DC motor 1112- for moving the cap up and down.
It controls the rotation of a pulse motor M3, etc. for horizontally moving the head assembly back and forth.

The recording head unit has four recording heads (Y, M.

C, B), and forms an image on the recording paper (fan fault paper) L in the image memory IN based on the image data obtained from the INS.At this time, ink supply to each part of the head, recovery processing, etc. This takes place under the control of the mechanism AM for the helad assembly.

In the two embodiments, each of the blocks described above is assembled on a separate printed board. The image memory has a storage capacity of 1 megabyte including the mask and slave.

Next, referring to FIG. 36, an outline of the operation of the apparatus performed when the power is turned on will be described.

First, when the power is turned on (step st),
Each unit having a CPU (MP, MO shown in Figure 35)
, AM) performs various hardware checks such as a memory check and a boat status check for each unit.

Next, main control of the entire device is transferred to the main processor MP.

- Check the presence or absence of recording paper, the presence or absence of ink, the opening/closing status of the door, the installation status of the recording head 110, etc. (Step S
3).

As a result, if it is determined that there is no error (step S0), the online mode is set and communication with the host computer He is enabled (step S5).

In online mode, image data sent from the host computer is stored in the image memories INN and INS.
When a predetermined amount of data is accumulated, the cap is lowered and the head assembly is advanced to the printing position to perform printing (image formation) (step S8). Even during this printing, image data is continuously received from the host computer IC. (that is, image data writing and reading are performed asynchronously), and such printing operations are repeatedly performed unless an error occurs (step S7).
).

Further, if the switch is pressed while the online mode is set in step S5, the device is disconnected from the host computer HC and enters the offline mode (step S8).

Next, a test print, which will be described in detail later, is performed (step S9). The test pattern used in this test print is stored in a ROM (not shown). After printing a predetermined amount of test patterns, the test printing is automatically stopped.

Thereafter, to return the device to online mode, the switch can be pressed again (steps S8→S5).

If the occurrence of an error is detected in step S7, the device is set to offline mode (step 5I).
O), This error refers to conditions such as jamming, running out of recording paper, or out of ink, so remove the causes of these errors. Step 2) Press the switch to return the device to online mode ( Step 512).

FIG. 37 is a flowchart illustrating the operation of this apparatus at the start of normal printing.

First, when the power is turned on (step 520), the recording head assembly is retracted to the home position (step 521), and then the cap is lowered (step 522).
), then the recording head assembly is advanced by a pulse motor and stopped at a print position corresponding to a predetermined number of pulses (step 523).

Then, head control for printing is performed (step 523).

FIG. 38 is a flowchart showing a control procedure for covering the front surface of the recording head assembly with a cap.

First, the recording head assembly is retreated to the home position. When the assembly reaches this home position, a predetermined output is obtained from the home position sensor (step 530).

Next, +24V is applied to the DC motor for driving the cap to raise the cap (step 531).

When the cap rises and reaches the predetermined cap position, a sensor output is obtained to notify that fact, and at that point the voltage applied to the DC motor is changed to +5V (step 532). Balances the torque of the motor and stops it.

Thereafter, a predetermined number of pulses are supplied to the pulse motor for driving the recording head assembly, thereby moving the assembly to the cap position (step 533).

Since the tip of the recording head assembly has already penetrated into the inside of the cap, the DC motor for driving the cap is disconnected from the power source (step 534).

Thus, the cap lowers under its own weight and the cap action is completed by zero or more engaging the recording head assembly.

Next, communication between the host computer or host system and the present image forming apparatus will be explained.

・While switching the Vap mill monitor, adjust the volume to the voltage value written on the top of the recording head unit.

5. Modification of recording surface forming means The recording surface positioned with respect to the recording head unit is 1
It can also be formed as follows.

First, in the example described above, the fan 138 provided in the assembly 130 was operated to blow air from the assembly 130 side to the platen 382 side in order to back up the adsorption of the recording paper P to the platen 382. In a modified example, the fan 138 is operated in the opposite direction so as to attract the recording paper P to the front surface of the assembly 130. In this case, on the front surface of the assembly 130, there are horizontal line-shaped protrusions 1 arranged on the L sides of the recording head.
The height of the No. 15 assembly 130 from the front is made higher than the height of the recording head. Further, the operation of the fan 390F for attracting the recording paper P to the platen 382 is stopped.

By doing so, the recording paper P can be attracted to the front surface of the assembly 130 by the suction action of the fan 138, and the distance between the surface of the recording paper P and the recording head can be maintained appropriately by the linear projections 115. Recording can be performed stably on the recording paper P. Furthermore, while the fan 138 continues to operate, the heater for heating the print head is controlled to keep the temperature inside the print head assembly 130 constant based on the detection result of a temperature sensor provided in the print head assembly 130.
