Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a printer-integrated digital camera.

[0002]

2. Description of the Related Art Conventionally, various printer-integrated digital cameras have been proposed, but none of them has been proposed in consideration of actual usability by combining a printer unit and a digital camera unit.

[0003]

Therefore, when the printer section is in a state other than the standby state, such as when the cartridge is replaced, when the photographing operation is started using the digital camera section in such a state, the tilt of the machine due to vibration or operation is caused. As a result, the inside of the machine becomes dirty, and as a result, the print image quality may be deteriorated. In particular, when the printer unit is of the ink jet type, the head is exposed at positions other than the standby position.
Liquid ink leaks, which can result in soiling inside the machine and soiling clothes.

Accordingly, a technical problem to be solved by the present invention is to provide a printer-integrated digital camera which does not cause any trouble when the printer unit enters a state other than a normal print standby state. It is.

[0005]

SUMMARY OF THE INVENTION The present invention provides a printer-integrated digital camera having the following configuration to solve the above technical problems.

A printer-integrated digital camera includes a digital camera unit for performing a photographing operation and a printer unit. The printer unit includes a head for recording on a recording medium,
And a replaceable cartridge having a recording material to be supplied to the head. The printer-integrated digital camera includes cartridge replacement detection means for detecting replacement of the cartridge, and digital camera section operation prohibition means for prohibiting operation of the digital camera section in response to detection by the cartridge replacement detection means.

In the above configuration, when the cartridge replacement detecting means detects the replacement of the cartridge (not only when the actual cartridge replacement operation is detected, but also when the actual cartridge replacement operation has not yet started, the cartridge replacement operation will be performed soon). The digital camera unit operation prohibiting unit prohibits the operation of the digital camera unit (including a case where the start is predicted). Thus, during the replacement of the cartridge, it is possible to prevent the vibration caused by the operation of the digital camera unit and the inclination of the machine due to the photographing operation from occurring.

According to the above configuration, it is possible to prevent the printer unit from vibrating or tilting during the operation of the printer unit, thereby preventing the quality of the print image from deteriorating. In addition, it is possible to prevent a printing agent such as ink from leaking and causing stains. Further, since the digital camera section does not operate during the cartridge replacement, it is safe to use.

Therefore, when the printer section is in a state other than the normal print standby state, it is possible to prevent a problem from occurring.

[0010] Specifically, the recording agent is an ink.
For example, when the printer unit is an ink jet system, ink which is a liquid recording agent is used, but even in such a case, ink does not leak during cartridge replacement. Therefore, no dirt or clothes are stained inside the machine.

Preferably, the apparatus further comprises an operation prohibition display means for displaying operation prohibition of the digital camera section. Thus, when the digital camera unit operation prohibition unit prohibits the operation of the digital camera unit, it is possible to know from the display of the operation prohibition display unit that the digital camera unit is in the operation prohibition state. Therefore, usability can be improved.

When the cartridge needs to be replaced, the printer unit is in a state other than the normal standby state. The cartridge replacement detection means detects this.

When the remaining amount of the recording material in the cartridge becomes small, the cartridge needs to be replaced. Therefore,
Preferably, the cartridge replacement detecting means detects the replacement of the cartridge by detecting the remaining amount of the recording material is small.

Before replacing the cartridge, it is necessary to open the cartridge chamber lid. Therefore, preferably, the cartridge replacement detecting means detects the replacement of the cartridge by detecting that the lid of the cartridge chamber is opened.

On the other hand, when the replacement of the cartridge is completed,
It is no longer necessary to prohibit the operation of the printer unit. Therefore,
Preferably, the apparatus further comprises a cartridge replacement completion detecting means for detecting the completion of replacement of the cartridge. The digital camera unit operation prohibiting unit cancels the operation prohibition of the digital camera unit when the cartridge replacement completion detecting unit detects the completion of the replacement of the cartridge.

9 (YES in FIG. 9), as shown in FIG. 9, first, the light emission timing of the flash 6 is calculated based on the photometric value in order to perform flash photography (# 111). Next, flash unit 1
It is determined whether or not the charge storage capacitor in 08 has already been charged with light necessary for light emission (# 112). If charging has not been completed (NO in # 112), the unfilled flag is set to "1". To start charging (# 113, # 11
4), the focus indication lamp 907 flashes (114a), and #
Return to 112 and wait for completion of charging.

When charging is completed (YES in # 112),
If the focus indication lamp 907 is blinking, it goes out (# 11).
2a, # 112b) and proceed to # 115. In # 115,
After the completion of the charging is confirmed, the charging is stopped, and it is determined at # 116 whether or not the unfilled flag is "1".

If the unsatisfied flag is "1"(# 116)
In YES), in the "0" this MiTakashikan flag # 117 waits until the switch S ₁ is turned off (# 11
8). Then, when the switch S ₁ is turned off (# 118
Then, the process returns to # 100, and a so-called release lock is performed.

On the other hand, if the unsatisfied flag is "0" in # 116 (NO in # 116), the flow shifts to # 119, where the subroutine of exposure control 2 is executed, and then the flow advances to # 120 in FIG. .

The subroutine of exposure control 2 follows the flow shown in FIGS.

That is, first, the interrupt is prohibited (# 4
01), the focus indication lamp 907 is turned on (# 401)
a), a determination whether or not the switch S ₂ is on (#
401a).

[0085] If the switch S ₂ is turned off (# 401
NO in b), if the switch S ₁ is turned on (# 401d
In YES), waits, if switch S ₁ is turned off (#
(NO in 401d), and proceeds to # 100 in FIG.

[0086] If the switch S ₂ is turned on (# 401
b) and if the display on LCD 905 is on,
The image to be displayed on the image display LCD 905 is locked, and the same image is continuously displayed (# 401x). Next, the camera shake amount is detected (# 401c), and the exposure time Tv and the aperture value Av obtained by the photometric calculation are output to the exposure control unit 106 (# 402). The exposure control unit 106 drives the aperture of the camera 1 based on these data, and outputs a shutter control signal to the timing generator 201 in accordance with the exposure time Tv to expose the CCD 101. When a signal indicating that the exposure has been started is input from the exposure control unit 106 (# 403), the CPU 100 starts a timer in the CPU 100 based on the flash emission timing obtained in # 111 (# 40).
4). The light emission of the flash 6 is performed at a timing after a predetermined time has elapsed from the start of exposure of the CCD 101.

Next, as shown in FIG.
Determines whether an exposure completion signal has been input from the exposure control unit 106 (# 405). This determination is made because the exposure time Tv is a predicted value. For example, if the brightness of the subject suddenly increases during the counting operation of the flash emission timer, the exposure control unit 106 does not need to reach the flash emission timing. May output an exposure completion signal.

That is, when the exposure control unit 106 outputs an exposure completion signal before the flash emission timing (YES in # 405), the process proceeds to # 408a, where the exposure operation is ended without causing the flash 6 to emit light.

If the flash emission timing is reached before the exposure is completed (NO in # 405, YE in # 406)
S), causing the flash 6 to emit light and the exposure control unit 1
06 to output a shutter close signal (# 407, # 40
8) The process proceeds to # 408a, and the exposure operation ends.

At step # 408a, the in-focus indication lamp 907 is turned off. Next, the image display on the screen display LCD 905 is unlocked, and the captured image from the CCD 101 is displayed on the monitor (# 408b). Then, it is determined whether or not the camera shake amount during exposure exceeds a predetermined value (# 408c). If not (NO in # 408c), only the image signal captured from the CCD 101 is stored in the image memory of the camera body 1. 209 is controlled (# 409). If it exceeds (YES in # 408c), the image signal from the CCD 101 is added to the camera shake information and written in the image memory 209 (# 408d, # 409). Here, information is added only when the camera shake is maximum, but the camera shake amount may be always recorded. When the above process is completed, an interrupt is enabled in # 410 and the process returns.

On the other hand, if it is determined in # 109 of FIG. 8 that the luminance is not low as a result of the photometry (NO in # 109),
A subroutine of exposure control 1 without flash emission is executed (# 110).

The exposure control 1 subroutine follows the flow shown in FIG.

That is, first, the interrupt is prohibited in # 301, and the focus indication lamp 907 is turned on (# 301
a), a determined on the switch S ₂ (# 301b).

[0094] If the switch S ₂ is turned off (# 301
NO in b), if the switch S ₁ is turned on (# 301d
In YES) waits, if switch S ₁ is turned off (# 3
(NO in 01d), the process proceeds to # 100 in FIG.

[0095] If the switch S ₂ is turned on (# 301
b) and if the display on LCD 905 is on,
The image to be displayed on the image display LCD 905 is locked, and the same image is continuously displayed (# 301x). Next, the camera shake amount is detected (# 301c), and the exposure time Tv and the aperture value Av obtained by the photometric calculation are output to the exposure control unit 106 (# 302). The exposure control unit 106 drives the aperture of the camera body 1 based on these data, and outputs a shutter control signal to the timing generator 201 in accordance with the exposure time Tv to expose the CCD 101. The CPU 100 receives a signal indicating that the exposure has been started from the exposure control unit 106 (# 303).
It is determined whether an exposure completion signal has been output from the exposure control unit 106 (# 305). When the exposure time Tv has been reached, the exposure control section 106 outputs an exposure completion signal (# 30).
If the answer is 5), the exposure operation ends.

When the exposure operation is completed, as in the processing of # 408a to # 410 in the exposure control 2 routine,
The in-focus display lamp 907 is turned off (# 305a), and the image display on the image display LCD 905 is unlocked (# 30).
5b), the image signal captured by the CCD 101 is written into the image memory 209 of the camera 1, and the amount of camera shake during the exposure operation is compared with a predetermined value (# 305c). YES), the camera shake information is added together with the image signal and written into the internal memory (# 305d, # 308). When the above process is completed, an interrupt is enabled in # 309 and the process returns.

When the exposure control subroutine in # 110 in FIG. 8 or # 119 in FIG. 9 is completed,
Go to 0, update the frame number by 1 and display it on the display 1
7 is displayed. Next, when shooting of all frames is completed and shooting of all frames in the image memory 209 is completed (YES in # 121), a warning is displayed or voiced in # 122 to call attention of the photographer. . No warning is given if recording is possible.

[0098] Then, the processing proceeds to # 123 in FIG. 10, the switch S ₁ is waiting to be turned off, the switch S ₁ is turned off (YES at # 123), CPU 100 is CCD101 the outputs a signal Turn off the power and 1
The shooting for the frame is ended (# 124).

After the above processing, it is determined whether or not the flash 6 has been charged for the next photographing (# 125). If charging is not completed (# 125
NO), the uncharging completion flag is set to “1”, and charging is started to complete charging (# 126, # 127), and # 1
Return to 25. On the other hand, if the charging is completed (YES in # 125), the unfilled flag is set to "0" and the charging is stopped. (# 128, # 129). And again, FIG.
To # 100, and repeat the above-described operations of # 100 to # 129.

Next, a description will be given of the processing executed when an interrupt occurs after # 104 in which the interrupt is enabled, with reference to the flowcharts of FIGS. This interruption occurs when the mode changeover switch 8 is set to the "print" mode position for instructing printing or the "reproduction" mode position for instructing reproduction, that is, when the switch S _PRT or S _REP is on, and Fifteen
Occurs when is operated.

When this interrupt occurs, it is determined in # 201 whether the unsatisfied flag is "1". If it is "1", it is determined that an interrupt has occurred during charging of the charge storage capacitor, and # 202 To stop charging once, and if "0", skip # 202 and switch S in # 203.
Determine if _PRT is on. If the switch S _PRT is on (YES in # 203), it is determined that the operation has shifted to the printing operation, the above-described battery check is performed (# 203a), and the above-described shooting prohibition process is performed (# 203).
b) After detecting the attitude of the camera body 1 (# 203c), which will be described in detail later, the process proceeds to # 204. On the other hand switch S
_{If the PRT} is off (NO in # 203), the process goes to # 2 in FIG.
Proceed to 23.

FIG. 29 and FIG. 30 correspond to # 203 of FIG.
13C is a detailed flowchart of the posture detection in # 217s of FIG. 12 described later.

FIG. 29 is a flowchart in the case where the inclination of the camera body 1 is not appropriate for printing but printing is permitted. In step # 802, the CPU 100 determines whether or not the inclination detection result of the posture detection unit 704 is at a level that hinders obtaining good print quality.

If it is determined that the inclination is at a level at which good print quality can be obtained, the routine returns. For example, the step of # 203c is completed, and the process proceeds to # 204 in FIG.

On the other hand, if it is determined in step # 802 that the inclination is at a level at which good print quality cannot be obtained, the flow proceeds to step # 804, issues a warning, and returns. As a mode of the warning, for example, a predetermined warning mark is displayed on the display 17. Alternatively, the focus indication lamp 907 blinks. Alternatively, an alarm sound is emitted.

FIG. 30 is a flowchart for the case where printing is prohibited when the inclination of the camera body 1 is not appropriate for printing. In step # 810, the CPU 100 determines whether or not the inclination detection result of the posture detection unit 704 is at a level that hinders obtaining good print quality.

When it is determined that the inclination is at a level at which good print quality can be obtained (NO in # 810), if the printing operation by the printer unit is prohibited, the printing prohibition is canceled (# 812). , # 714), and returns.

If it is determined that the inclination is at a level at which good print quality cannot be obtained, the flow shifts to step # 820, and a warning similar to step # 804 in FIG. 29 is issued. After the warning is given for a predetermined time (# 822), the printing operation by the printer unit is prohibited (# 824), and the process returns.

By the way, the inclination of the camera body 1 occurs when the place where the camera body 1 is placed for printing is inclined, or when the user holds the camera body 1 by hand. Alternatively, the inclination may be measured, and “warning only” or “prohibition” may be used as appropriate.

For example, in the above embodiment, the mode is completely switched between the camera mode and the printing mode. However, the mode may be such that printing is performed simultaneously with shooting. In such a case, printing should be permitted in hand-held shooting in principle, and printing should be prohibited only in an extremely inclined posture such as vertical shooting.

Returning to FIG. 11, at step # 204, the display 17
Then, a display indicating that the print mode is set is displayed, and then it is determined whether the access button 14 has been turned on from off, that is, whether or not the access button 14 has been pressed (# 205). Access button 1
If the access button 14 is turned on (YES in # 205), the process proceeds to # 206, and if the access button 14 remains off or on, or is turned off from on (NO in # 205), # 21 is reached.
Move to 0.

In step # 206, it is determined that the access button 14 has been pressed, and the frame number is incremented by 1 and the display 17
And an address controller (not shown) outputs address data corresponding to the frame number in order to reproduce an image corresponding to the frame number (# 20).
7). After waiting for the time for the above processing in # 208,
LCD for displaying image information corresponding to the current frame number
The image is displayed on the monitor 905 (# 209). Then, the presence or absence of camera shake is determined based on camera shake information corresponding to the display image (# 209a), and if there is no camera shake (# 209).
(NO at a), and the process directly returns to # 205. On the other hand, if there is camera shake (YES in # 209a), the camera shake display 602 is turned on as shown in FIG.
During 0, it is displayed that the frame displaying the monitor image has camera shake (# 209 '), and the process returns to # 205. Thus, each time the access button 14 is turned on, the frame number is incremented by one, and the process of displaying the image corresponding to the frame number on the image display LCD 905 is repeated.

On the other hand, in # 210, the access button 14
Is turned on, and if it is turned on (# 21)
If it is 0 (YES in step # 21), the process returns to step # 205.
(0 and NO), the process proceeds to # 211 in FIG.

Next, in FIG. 12, the access button 1
When access button 15 is turned on in place of # 4 (# 21)
If the access button 15 remains off or on, or is turned off from on (NO in # 211), the process proceeds to # 216.

At step # 212, it is determined that the access button 15 has been pressed, and
And the address controller outputs address data corresponding to the frame number to reproduce an image corresponding to the frame number (# 213). # 214
After waiting for a time for processing, the image information corresponding to the current frame number is displayed on the image display LCD 905 on the monitor (# 215). Then, based on the camera shake information corresponding to the displayed image, it is determined whether or not the image of the frame contains a camera shake (# 215a). If there is no camera shake, the process directly returns to # 211. # 209 '
Similarly, the camera shake display 602 is turned on, and it is displayed that the frame of the monitor image display 60 has a camera shake (# 21).
5b) Return to # 211. Thus, each time the access button 15 is turned on, the frame number is decremented by one, and the process of displaying the image corresponding to the frame number on the image display LCD 905 is repeated.

On the other hand, in # 216, the access button 15
Is turned on, and if it is turned on (# 21)
If YES in # 6, the process returns to # 211 and if it is off (# 21)
(NO at 6), and proceeds to # 250.

At # 250, it is determined whether or not the erase switch _SE is turned on. When the erase switch S _E is turned on (YES at # 250), the image display LCD90
5 to delete the image displayed on the monitor (# 25
1), the process proceeds to # 203 in FIG. On the other hand, when the erase switch _SE is not turned on (NO in # 250),
# Proceeds to 217 to determine whether the switch S ₂ is turned on.

Switch S_TwoIs not turned on (# 21
7 is NO), it is determined that printing is not performed, and
Returning to # 203, the above processing is repeated. On the other hand,
Chi S _TwoIs turned on (YES in # 217),
The presence or absence of a report is determined (# 217a), and if there is no camera shake,
(NO in # 217a), camera body as in # 203c
After detecting the posture of No. 1 (# 217s), proceed to # 218.
If there is camera shake (YES in # 217a), camera shake table
Indicator 602 blinks, and the frame to be printed
A warning that there is camera shake (# 207 '), within a predetermined time
Switch S again_TwoIs on, go to # 218, where
If it is not turned on again within the fixed time, the process proceeds to # 203 (#
217c, # 217d).

In step # 218, the CPU 100 outputs a print command signal to shift to the printing operation. Upon receiving the signal, the image processing unit 300 starts signal processing for a printing operation. The CPU 100 displays on the display 17 that the printing is being performed (# 21).
9), the print operation is controlled (# 220).

The control of the printing operation is executed according to the sequence shown in FIG.

That is, the CPU 100 first feeds one sheet of printing paper to the printing position (# 510). Next, preliminary ejection is performed at the home position of the recording head 5 'to make the printing operation more reliable (# 520).
The clogging of the recording head 5 'is eliminated, and the ink or the like of the ink from which the moisture has evaporated adheres to recover the nozzles whose performance has been reduced.

Next, CPU 100 starts the printing operation (# 530). That is, the in-focus indication lamp 907 is turned on (# 531), the image information is subjected to image processing for printer output, and the printer unit 111 is pre-toned out (# 532).

FIG. 25 is a detailed flowchart of the printing operation of # 532 in FIG.

First, at step # 532-1, the CPU 100
Camera body 1 using acceleration sensor of camera shake detection section 400
Of vibration degree is input. Next, in # 532-2,
Based on the data previously input in # 532-1, it is determined whether or not the vibration level is at a level that hinders obtaining good print quality.

If it is determined that the degree of vibration is at a level at which a good print quality can be obtained, then at step # 532-3
After performing a predetermined amount of operations such as moving the recording head 5 ', ejecting ink, and feeding the recording paper 11' as a normal printing operation, the process proceeds to the next step # 532-4. # 5
In step 32-4, the CPU 100 determines whether or not printing of the current page has been completed. If not completed, the process returns to # 532-1 unless an error is detected (# 532-1).
If the error is detected, the process proceeds to # 535 in FIG. 19 (YES in # 532-10).

At step # 535 in FIG.
Blinks (# 535), and when the error is cleared (YES in # 536), the process proceeds to # 532, where the printing operation is continued, while when the error is not cleared (# 5).
(NO at 36), and waits for the switch _{SPPT to} be turned off (# 537). When the switch S _PRT is turned off, the printing is stopped (# 538), the focus indication lamp 907 is turned off (# 539), and the process returns to # 100 in FIG.

If the printing of the current page has been completed at # 532-4 in FIG. 25, the step of # 532 in FIG. 19 is completed, and the flow shifts to # 540 in FIG.

On the other hand, if it is determined in step # 532-2 of FIG. 25 that the degree of vibration is at a level at which good print quality cannot be obtained, the flow shifts to step # 532-5, where the recording head 5 'is moved to the home position. Evacuated to the position and the next # 53
In 2-6, a predetermined time wait is performed. After this, the CPU
100 is # 532-7, # 532-8, and the above-mentioned #
The vibration degree input and the judgment of the vibration degree are performed in the same manner as in the steps 532-1 and # 532-2.

When it is determined that the degree of vibration is large (# 5
(YES at 32-8), then continue to # 532-6, # 532
-7, a series of operations of # 532-8 is continued. If this is repeated for a predetermined time (YE in # 532-11)
S), the recording paper 11 'in the middle of printing is discharged in # 532-12, and the power is turned off in # 532-13.

If it is determined that the vibration level is small and good print quality is obtained (NO in # 532-8), the recording head is set to the home position in # 532-5 in the next # 532-9. Return to the position immediately before evacuation, # 53
Jump to 2-3.

When the predetermined printing operation in # 532 of FIG. 19 is completed, the printing paper 11 'printed by the printer unit 111 is fed from the outlet 901 of the camera body 1 to a position where the printing paper 11' does not fall. (# 54
0), the focus indication lamp 907 is turned off (# 942).
Next, the CPU 100 sends a print end signal, returns the carriage 4 'to the home position, and performs a cleaning operation (# 550).

The above-mentioned preliminary ejection and cleaning operation are performed to make the recording more effective in an ink jet recording type printer, and the recording head 5 'is cleaned by a cleaning means such as a suction pump or a cleaning blade. Is what you do.

At step # 221 in FIG. 12, the process waits for the printing to be completed. When the print completion signal is output (# 22)
1 is YES), the display 17 indicates the completion of printing (# 2)
22). With the above operation, printing of one frame is completed, and the flow returns to # 203 in FIG.

On the other hand, in step # 203 of FIG.
_{If PRT} ON is not detected (N in # 203)
O), it is determined that the printing operation is not performed, and
223 is performed. In # 223, the reproduction switch S _REP
It is determined whether is turned on. If the reproduction switch S _REP is off (NO in # 223), the image display LCD 9
It is determined that the reproduction display is not performed according to the step # 05 in FIG.
Move to 235. On the other hand, if the reproduction switch S _REP is on (YES in # 223), the above-described battery check is performed (# 223a), and the above-described photographing prohibition process is executed (# 223b). LCD9 for
A reproduction mode indicating that reproduction is to be performed according to 05 is displayed (# 224).

In this reproduction mode, it is determined whether or not the access button 14 or 15 has been turned on (# 225, # 230).

While the access button 14 is off or on,
Alternatively, when the power is turned off from on (NO in # 225),
Shift to # 229. On the other hand, when the access button 14 is turned on (YES in # 225), the frame number is increased by one and displayed, and the address controller responds to the frame number in order to reproduce the image corresponding to this frame number. Output address data (# 226, # 22
7). Next, as described above, the image information corresponding to the current frame number is displayed on the monitor (# 228). And #
Returning to 225, the frame number is incremented by one each time the access button 14 is turned on, and the process of monitoring and displaying the image corresponding to the frame number on the image display LCD 905 is repeated.

On the other hand, in # 229, the access button 15
Is determined to be on, and if it is on (# 22)
If the answer is NO in # 9, the process returns to # 225, and if it is off (# 22)
(NO at 9), and proceeds to # 230.

Next, when access button 15 is turned on instead of access button 14 (YES in # 230), #
Then, when the access button 15 remains off or on, or is turned off from on (# 230)
NO), and proceeds to # 234.

In step # 231, it is determined that the access button 15 has been pressed, and the frame number is reduced by one and displayed, and the address controller responds to the frame number in order to reproduce the image corresponding to this frame number. The address data is output (# 231, # 232). Next, as described above, image information corresponding to the current frame number is displayed on the monitor (# 233). Then, the process returns to # 230, and every time the access button 15 is turned on, the frame number is decremented by 1, and the process of displaying the image corresponding to the frame number on the monitor is repeated.

On the other hand, in # 234, the access button 15
Is determined to be on, and if it is on (# 23)
If YES in # 4, the process returns to # 230, and if it is off (# 23)
(NO at 4), and proceeds to # 252.

[0141] In # 252, it is determined whether or not the erase switch S _E is turned on. When the erase switch _SE is turned on (YES in # 252), the image displayed on the monitor is erased (# 253), and the process returns to # 203. When the erase switch _SE is not turned on (# 252). NO),
The process returns to step # 203.

The access button 14 after # 235 in FIG. 14 is for shooting, that is, not for printing or reproducing.
And 15 are the determination routines. Access button 15
Is turned on (YES in # 235), the photographing lens 3 is switched to the tele side (# 236). When the access button 14 is turned on (YES in # 237), the photographing lens 3 is switched to the wide side (# 238). . Access button 14
When both are off, the switching of the taking lens 3 is not performed. And at the end of this interrupt routine,
It is determined whether the unsatisfied flag is “1” (# 23)
9). If the unsatisfied flag is "1" (YE in # 239)
S) The charging operation interrupted in an uncharged state was restarted because an interruption occurred during charging (# 240).
Thereafter, the process returns. If the unsatisfied flag is “0”, the process returns.

Next, the ink jet cartridge 903
The interrupt processing at the time of replacement of the server will be described.

The interrupt process of FIG. 26 is started when the remaining ink amount detecting unit 42 detects that the remaining amount of ink in the cartridge 903 has decreased.

First, at step # 601, it is displayed that the cartridge 903 needs to be replaced. For example, the display 17 blinks an ink drop mark. And #
In step 602, it is checked whether or not the cartridge needs to be replaced. If the cartridge needs to be replaced, the process proceeds to step # 602a. If the cartridge does not need to be replaced, the process proceeds to step # 609.
Proceed to.

In step # 602a, the open / close detection switch 904
Check the opening / closing of the cartridge chamber lid 602 by a

If the cartridge chamber cover 602 is closed (NO in # 602a), the process proceeds to # 60 until a predetermined time has elapsed.
Returning to step 2 (NO in # 602c), if a predetermined time has elapsed (YES in # 602c), it is determined that a trouble has occurred and the power is turned off (# 611).

If the cartridge chamber cover 602 is open (YES in # 602a), the cartridge is driven to the replacement position (# 602b). Then, the photographing operation of the digital camera unit is prohibited, and a display indicating that the photographing operation is prohibited is performed (# 603). For example, the X mark is superimposed on the camera mark and displayed on the display 17. Here, the user normally performs a cartridge replacement operation.

Next, in step # 605, the completion of the cartridge replacement is confirmed. If the cartridge replacement has not been performed, the process returns to step # 603. As a method of detecting the completion of the cartridge replacement, light is applied to the cartridge, the empty is detected by the reflection, the remaining amount is detected by counting the number of dots, and these two methods are used.
There is a combination of two detections.

When the open / close detection switch 904a detects that the cartridge chamber cover 902 is closed (# 60).
(YES in 6), drive the cartridge to the home position in # 606a, permit the photographing operation of the digital camera unit in # 607, and erase the display of the photographing operation prohibition started in # 601. Then, in step # 609, the display indicating that the cartridge needs to be replaced is deleted, and the routine returns.

When the cartridge 903 is not replaced within a predetermined time (YES in # 610), or when the cartridge chamber cover 902 is not closed (YE in # 612).
In S), it is determined that a trouble has occurred, and the power is turned off (# 61).
1).

By the way, the cartridge 903 is arbitrarily replaced, not only when the remaining amount of ink is low.
In the interrupt processing of FIG. 27, when the cartridge chamber cover 902 is opened, the cartridge replacement interrupt processing 2 is started.

First, at # 602b ', the cartridge is driven to the replacement position. Next, in step # 603 ', the photographing operation of the digital camera unit is prohibited, and a display indicating that the photographing operation is prohibited is displayed. Then, it waits until the replacement of the cartridge 903 is completed (# 605 '), and when the replacement is completed, waits for the cartridge chamber cover 902 to be closed (# 60).
6 '). When the cartridge chamber cover 902 is closed (# 6)
If YES in step 06 '), the cartridge is driven to the home position in step # 606a', the photographing operation of the digital camera unit is permitted in step # 607 ', the display indicating that the photographing operation is prohibited is deleted, and the routine returns.

If the cartridge is not replaced within a predetermined time (YE in # 610 'or # 612')
S), it is determined that a trouble has occurred, and the power of the printer unit is turned off (# 611 ').

Next, an interruption process when a print error is detected will be described.

The print error detection interrupt processing of FIG. 28 is started when a print error is detected.

First, in step # 702, a print error is displayed. For example, the entire display 17 is blinked. The print error is, for example, a jam of a print sheet or a scan failure of the printer head 5 ′. The jam of the print paper 11 ′ can be detected by the feeding abnormality detection unit 702 (see FIG. 1). The scanning failure of the printer head 5 'can be detected by monitoring the position and moving speed of the printer head 5'.

Next, it is checked in step # 704 whether the print error has been resolved. If the print error has been resolved (NO in # 704), the process proceeds to # 718, where printing is continued. On the other hand, if the print error has not been resolved (YES in # 704), the flow proceeds to # 706. The print error is due to removal of the jammed print paper 11 ', confirmation of the scanning operation of the printer head 5', and the like.

In step # 706, the use of the digital camera is prohibited, and in step # 708, the process waits until the error is cleared. When the error is released (YES in # 708), the use of the digital camera is permitted in # 710, and the error display started in # 702 is deleted in # 712, and the error display in # 203 of FIG. 11 is deleted.
Proceed to. The reason for proceeding to step # 203 in FIG. 11 is that the print instruction from which the error has been canceled has failed, and a print instruction is required again.

If the error is not cleared within the predetermined time (NO in # 714), it is determined that a trouble has occurred, and the power of the printer unit is turned off (# 716).

In the printer-integrated digital camera described above, when the printer section is in a state other than the normal standby state, it is possible to prevent a problem from occurring.

The present invention is not limited to the above embodiment, but can be implemented in various other modes.
