In such a case, once a device failure or jam occurs, it tends to occur frequently unless the device is repaired. When all of this information is stored in the memory, the capacity of the memory is inevitably large. Even if a relatively large capacity memory is used, the amount of error history storage is naturally limited, and if errors that frequently occur are stored consecutively, the old history will be deleted in chronological order, and a sufficient error history will be known. There is a problem that it is not possible.

In consideration of the above facts, the present invention efficiently stores necessary maintenance information in a memory having a relatively small capacity, reads it out, and records an error history so that maintenance can be performed efficiently in a short time. It is an object of the present invention to obtain an information storage method for an image recording device that enables the above.

[0008]

According to the first aspect of the present invention, the replacement information indicating the replacement time of the consumables such as the remaining amount of the image recording material accommodated in the magazine and the remaining amount of the solvent, and the two types of image recording. Various information contents of jam information shown when a clogging of a material conveying system is detected and failure information shown when a failure of each component of the apparatus is detected are stored in a memory in the order of occurrence. In this case, since the storage amount is predetermined (for example, 99 pieces of information), when the storage amount exceeds the predetermined storage amount, the oldest information is deleted, and new information is stored in a so-called scroll manner.

Generally, a jam in the transport system often occurs a plurality of times at the same place, but it is not necessary to store the jam each time.

Therefore, in the present invention, when the information other than the exchange information is detected among the various information, the information to be compared with the immediately preceding information is compared, and if they are the same, the storage of the detected information content is omitted. To do. As described above, by avoiding the continuous storage of the same information, necessary information can be effectively stored in a limited storage amount, and the reliability of the information at the time of maintenance is improved.

Next, the operation of this embodiment will be described. In the image recording apparatus 10 having the above-described configuration, the sensitive material magazine 14 has the storage unit 2
After being set within 00, the photosensitive material 16 is pulled out by the nip roller 18 and cut into a predetermined length by the cutter 20. The cut photosensitive material 16 is conveyed and inverted by the conveying rollers 19, 21, and 23, and is conveyed to the exposure unit 22 with its photosensitive (exposure) surface facing upward. When the photosensitive material 16 is nipped by the conveying roller 26, the driving of the conveying roller 26 is temporarily stopped, and the photosensitive material 16 is in a standby state immediately before the exposure unit 22.

On the other hand, while the photosensitive material 16 is being conveyed, the original 54 on the original placing plate is press-cleaned.

That is, first, the light source 40 is activated, and the reflecting mirror 46 enters the optical path of the image light with which the exposure unit 22 is irradiated, and the moving mirrors 42A and 42A.
The light emitted through B and the fixed mirror 44 is reflected in a substantially right angle direction. The reflected light is incident on and detected by the light detection sensor 56, whereby the image density of the image of the document 54 (in other words, whether the image of the document 54 is a print document or a photo document). Is measured, and the exposure conditions of the color adjustment filter (CC filter) and the aperture slit plate 52 are set based on the measured values.

Then, the reflecting mirror 46 is removed from the optical path of the image light, and the light source 40, the moving mirrors 42A, 4 and
2B and the lens unit 48 return to the home position (image scanning start position).

Here, the driving of the carrying rollers 24 and 26 is started again, and the photosensitive material 16 is exposed to the exposing section 22.
At a predetermined speed. In this case, since the guide plate 28 and the exposure surface glass 30 are arranged in the exposure section 22, the photosensitive material 16 is flat (while the deformation is corrected) and passes between the two conveying rollers (exposure section). .

At the same time when the photosensitive material 16 is conveyed (passes through the exposure section 22), the light source 40, the moving mirrors 42A and 42B, and the lens unit 48 move along the document placing plate 50, and are placed on the document placing plate 50. The document 54 placed is irradiated with light, and the reflected image light (image light) is scanned and exposed on the photosensitive material 16 located in the exposure section 22 via the fixed mirror 44.

After the exposure is started, the exposed photosensitive material 16 is sequentially guided by the guide plate 27 and inverted (that is, the image exposure surface is directed downward), and then the conveying roller 2 is used.
It is sent to the water application section 62 by 9, 31, 33, and 35.

In the water coating section 62, the photosensitive material 16 is sent between the guide plate 70 and the coating tank 64, and further,
It is nipped and conveyed by the squeeze roller 68. here,
Water is filled (supplemented) in the coating tank 64. Therefore, the photosensitive material 16 fed between the guide plate 70 and the coating tank 64 is coated with water by the supply roller 66, and further, the squeeze roller 68. As a result, excess water is removed and the water passes through the water application section 62.

In this case, since a plurality of rows of ribs 76 are formed on the bottom of the coating tank 64 so as to be inclined with respect to the conveying direction of the photosensitive material 16, the photosensitive material 16 is formed between the guide plate 70 and the coating tank 64. The frictional resistance when passing between the two is reduced, and scratches at certain positions of the photosensitive material 16 are prevented. Furthermore, since the ceramic heater 102 is attached to the guide plate 70 to raise the temperature of the water filled in the coating tank 64 to a predetermined temperature (for example, 40 ± 2 ° C.), the photosensitizer passing through the coating tank 64 is exposed. The permeation amount (infiltration amount) of water into the emulsion surface of the material 16 increases and the saturation amount is certainly reached.

The photosensitive material 16 coated with water as the image forming solvent in the water coating section 62 is squeeze roller 6
8, the toner is sent to the thermal development transfer unit 104.

On the other hand, the image receiving material 108 is also the image receiving material magazine 10.
The cutter 1 is pulled out from the 6 by the Nipro roller 110.
After being cut to a predetermined length by 12, the upper conveyance guide plate 182 and the lower conveyance guide plate 18 of the image receiving material conveying section 180 are cut.
4 and is fed to the heat development transfer section 104.

In this case, after cutting the image receiving material 108, the nip by the nip roller 110 is released, and the image receiving material 1
Deformation and change in physical properties due to nipping of the tip portion (image forming surface) of 08 for a long time are prevented. Further, a plurality of ribs 188 and 192 are formed on the upper conveyance guide plate 182 and the lower conveyance guide plate 184 of the image receiving material conveying section 180, so that the image receiving material 108 can be conveyed quickly without being scratched.

In the heat development transfer section 104, the heating drum 11
6 between the outer circumference and the laminating roller 120
And the image receiving material 108 is fed.

Further, here, the image receiving material 108 conveyed to the heat development transfer section 104 is synchronized with the conveyance of the photosensitive material 16,
The photosensitive material 16 has a predetermined length (20 m in this embodiment).
m) In the preceding state, it is sent between the laminating roller 120 and the heating drum 116 and superposed.

The photosensitive material 16 and the image receiving material 108, which are superposed by the laminating roller 120, remain in the superposed state with the heating drum 116 and the endless pressure contact belt 11.
It is sandwiched between the heating drum 116 and the heating drum 116, and is approximately 1/2 round (between the winding roller 134 and the winding roller 140).
Be transported to. When the photosensitive material 16 is heated during this nip conveyance, it releases a movable dye, and at the same time, this dye is transferred to the dye fixing layer of the image receiving material 108 to obtain an image.

Further, of the photosensitive material 16 and the image receiving material 108 sandwiched between the endless pressure contact belt 118 and the heating drum 116, both ends in the width direction of the photosensitive material 16 located outside the heating drum 116 are located inside. Since the image receiving material 108 protrudes from both end portions in the width direction of the image receiving material 108 and is superposed on the image receiving material 108, the protruding portion is in close contact with the outer periphery of the heating drum 116.

After that, when the photosensitive material 16 and the image receiving material 108 are nipped and conveyed and reach the lower portion of the heating drum 116, the peeling claw 154 is moved by a solenoid (not shown) and precedes the image receiving material 108 by a predetermined length. The peeling claw 154 engages with the leading end of the conveyed photosensitive material 16 to peel the leading end of the photosensitive material 16 from the outer periphery of the heating drum 116.

The peeled photosensitive material 16 is wound around the bending guide roller 142 and then conveyed by the photosensitive material discharge roller 158, and is accumulated in the waste photosensitive material storage box 178 by the photosensitive material discharge roller 160.

On the other hand, the heating drum 1 separated from the photosensitive material 16
Image receiving material 108 moving while being in close contact with 16
Moves between the heating drum 116 and the peeling claw 154 separated from the outer periphery thereof, and is guided by the material receiving guide 166 and sent to the peeling roller 174. Further, here, the material is peeled from the outer periphery of the heating drum 116 by the peeling roller 174 and the peeling claw 176, and the material receiving guide 17
While being guided to 0, it is conveyed by the receiving material discharge roller 172 and accumulated on the tray 177.

Here, in the present embodiment, the control device 1 receives a jam in the transport system of the photosensitive material 16 and the image receiving material 108 which occurs during processing, failure information of each part of the apparatus, and replacement information of consumables.
It is stored in 96 memories. This memory storage routine will be described with reference to FIG.

In step 350, if an error occurs during processing, a symbol corresponding to the error content is set, and in the next step 352, whether this error symbol is exchange information or not.
Judge whether it is failure information or jam information. Here, if it is determined that the information is the failure information or the jam information, step 35
4, the previous error symbol (error symbol stored in the address "1") is read out, and then these are compared in step 356.

If they match as a result of comparison, it is judged that it is not necessary to store such continuous information, and the process returns to the main routine.

If it is determined in step 356 that they do not match, the process proceeds to step 358. In addition,
When it is determined in step 352 that the information is the exchange information, steps 354 and 356 are skipped and the process proceeds to step 358.

At step 358, the stored error symbol is shifted to the address "2" and thereafter. As a result, the information stored in the address "99" is erased.

At the next step 360, the newest error symbol is stored in the address "1", and the process returns to the main routine.

As described above, in this embodiment, only the failure information and the jam information are canceled without being stored in the memory when they match the previous information. This allows
It is possible to store a large number of different types of information within a limited storage amount without storing a large amount of the same information. Therefore, it can be effectively used as information at the time of maintenance.

Next, the operation procedure of the error history mode will be described with reference to the flowchart of FIG.

Mode setting key 20 on operation panel 180
When the user operates 8 and further operates "7" on the ten-key pad 184, the process shifts from the normal processing routine to the error history mode control routine shown in FIG.

In step 380, the lamp corresponding to the magnification setting lamp "100" is turned on, and it is displayed that the error history mode is set.

At the next step 382, the variable I is set to 1, then at step 384, the address "1" is displayed on one of the LCD display portions 186, and the step 386 is performed.
Then, the symbol of the latest error content is displayed on the other LCD display unit 188.

Here, steps 388 to 40
In 6, display control is performed, and the process proceeds to step 408. That is, every time the recording start key 182 or the magnification down key 194 is operated, the addresses are 1, 2, 3, ... 98, 9
The error symbols are displayed in order from the newest (steps 388, 390, 392, and so on).
394, 396). Further, every time the scale down key 194 is operated, the address is displayed as 99, 98 ... 2, 1, 99, and accordingly, the error symbols are displayed in the oldest order (steps 398, 400, 402, 404). , 40
6).

At step 408, the mode setting key 20
It is determined whether or not 8 is operated, and in the case of a negative determination,
Returning to step 388, the display control is repeated, and in the case of a positive determination, the process proceeds to step 410, the lamp indicating the error history mode is turned off, and the error history mode ends.

As described above, in this embodiment, as shown in FIG. 5, the error history is not stored in the memory in the order of occurrence, but only the failure information and the jam information are not continuously stored and are limited. Since the stored amount (99) is effectively used, a lot of different kinds of information can be known during maintenance. For this reason, the context of failure, jam, and various types of exchange information becomes clear, and maintenance, trouble analysis, etc. can be performed in a short time.

[0101]

As described above, the information storage method for an image recording apparatus according to the present invention efficiently stores necessary maintenance information in a memory having a relatively small capacity, reads it out, and knows an error history. It has an excellent effect that maintenance can be efficiently performed in a short time.
