Abstract

PURPOSE:To prevent photographing with a stroboscope being uncharged when a self mode is set for self-timer photographing by charging a main condenser despite that a charge completion mode is set or not. CONSTITUTION:When a self switch 16 is operated for self-timer photographing, the self mode is set and processing to forcibly charge the main condenser of the stroboscope 32 is performed. When a light emitting mode is set based on a photometry mode and when the stroboscope is not charged, releasing is prevented. Therefore, when photographing in the self mode is performed and when the stroboscope emits light, it is not necessary to confirm the charging completion of the stroboscope. The stroboscope emits light interlocking with releasing so that proper exposure can be performed. Thus, a failure in photographing, missing of a shutter chance, etc., can be prevented to the utmost.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a camera in which a single power supply battery is used to drive a lens and operate a motor for film feeding, as well as charge a main capacitor of a strobe. In particular, the present invention relates to a camera with a strobe that reliably charges the strobe when taking pictures using a self-timer.

[Conventional technology]

2. Description of the Related Art Fully automatic cameras, which are equipped with an automatic exposure function, an autofocus function, an automatic film feeding function, a strobe device, etc., have become popular so that photography can be easily performed. Additionally, cameras are generally equipped with a self-timer, which allows the shutter to open with a delay after the release operation, making it convenient for special photography.

With conventional cameras equipped with strobes, when using the self-timer to take photos with a strobe, it is necessary to confirm that the strobe's main capacitor is fully charged by lighting up a neon lamp, etc., then release the shutter and activate the self-timer. It's Nishide.

[Problem that the invention seeks to solve]

As mentioned above, with conventional cameras equipped with strobes, you have to confirm that the strobe is fully charged before taking a self-timer photo. The shutter may be locked due to insufficient light, or the flash may not fire when taking pictures.

Also, there is no problem with strobes that are controlled to automatically charge when the voltage drops below a certain level, but there are strobes that do not charge for a predetermined period of time after charging is complete. When shooting, the camera is released within this predetermined time, but when using self-timer shooting, this predetermined time elapses while the camera is fixed on a tripod or the composition is decided, and the flash discharges naturally. There is a risk that the flash will not fire even if the camera is released.

As a result, a photo opportunity may be missed or a photograph may be taken with insufficient exposure.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a camera with a strobe that prevents as much as possible from taking a picture without charging the strobe when the self-timer is activated to take a picture in self-mode.

[Means for solving problems]

In order to achieve the above object, the camera with a strobe according to the present invention has a strobe device that sets a charging complete mode when charging of the main capacitor is completed, and does not perform a charging operation while the charging complete mode is set. In the camera, when a self-mode is set for self-timer photography, the main capacitor is charged by the self-mode set signal regardless of whether or not the charge complete mode is set.

[For production]

When performing self-timer photography, the self-switch is turned on, which sets the self-mode and also sends the charge start command to start charging the main capacitor of the strobe. Then, when you release the camera after charging is complete, the timer will count the predetermined time.

The shutter is opened.

When shooting, press the release button slightly to release the first
The step release switch 5 is turned on, which measures the distance to the subject and brings the photographic lens into focus. This focusing operation is performed by an autofocus circuit (AF circuit) 33, which calculates a subject distance using the CPUI based on distance information obtained by a distance sensor, and sends the result to the AF circuit 33.

The operation of the strobe-equipped camera according to the present invention constructed as described above will be explained using the flowcharts shown in FIGS. 3 to 14.

FIG. 3 is a flowchart at the time of initial setting after filling the power supply battery 25. At the time of filling, the power is turned on (step 201), the zoom system processing mode is set and stored (step 202), and the CPU 1 is turned on. The output port is set (step 203), the RAM is cleared (step 204), and the shutter is checked (step 206) for 2 seconds (step 205). 25 has been released, the shutter may not have returned to its initial position. In such a case, the shutter is returned to its initial position in step 206. Then, the state of the back cover switch 24 is detected and it is determined whether the back cover is open or not (step 207). If YES, this means that the film is being loaded or taken out, so shooting continues. Since there is no such thing, step 301 (
Proceed to step 4 (shown in Figure 4). If the determination in step 207 is NO, the film may be loaded, and the process proceeds to step 208, where the rewind switch 21 is turned off.
It is determined whether or not it is N. The result of that judgment is N
In the case of o, if the film is loaded, shooting will continue and the film will be wound, so the initial mode is set and memorized (step 209).
, proceed to step 301. If the result of the determination in step 208 is YES, it means that the power battery 25 was replaced while the film was being rewound, and therefore, after 0.5 seconds (step 210), a signal is sent from the port 1n. Based on this, the motor driver circuit 31 drives the motor 30 so that the motor 30 rotates for film feeding (MF) (step 211), and the process proceeds to step 1001 (shown in the 11th diagram) to perform film rewinding processing. .

FIG. 4 is a flowchart when the camera is on standby for photographing or other purposes, and in step 301 it is determined whether or not the camera is in a zoom processing mode. The result is YES
If S, the processing mode of the zoom system is reset (step 302), and then step 502 (shown in the sixth figure)
Proceed to. The result is N.

, an interrupt condition is set to wait when each switch is operated (step 303).
), the CPUI input/output ports are set (step 304), and in this state it becomes standby (step 3).
05), it is determined whether each switch has been operated, that is, whether there is an interrupt (step 306);
If the determination result in step 306 is No, the process returns to step 306 again, and this state continues until a YES determination is made.

If the determination result in step 306 is YES, it is determined which switch was operated. first,
In step 307, it is determined whether the main switch 2 (SM) is operated to open or close the barrier. If the result is YES, it means that the photographing will take place or that the photographing has ended, and the photographing lens needs to be moved to a position suitable for photographing or to a position that does not interfere with closing the barrier. , step 501 (sixth
), or if the determination result in step 307 is No.
When there is no operation of main switch 2,
Proceeding to step 308, it is determined whether the wide switch 7 (SW) or the tele switch 8 (TS) has been operated. If the result of this determination is YES, the process advances to step 501 to move the photographing lens. Step 30
When the determination result in step 8 is No, it means that neither the tele switch 8 nor the wide switch 7 has been operated, so the process advances to step 309. In step 309, the release button is slightly pressed and the first stage release switch 5 (
SPi) is turned on. The result is Y
When it is ES, it is a case where photography is performed, so
To perform shutter processing, the process proceeds to step 601 (FIG. 7). If the first stage release switch 5 is not turned on, the process proceeds to step 310, where it is determined whether or not the back cover has been opened or closed. If the determination result is YES, the process proceeds to step 311, where it is determined whether the shutter is locked, that is, whether the S lock mode is in effect. When the result of step 311 is YES, the process proceeds to step 1301, and when the result is No, step 7
Proceed to step 01, when the determination result in step 310 is No,
That is, if the camera back is not operated to open or close, the process proceeds to step 312, and the self-switch 16 (SSELF) is set to O.
Determine whether or not the answer is N. Self switch 16 is ON
When this happens, it is a case of performing self-timer photography, and in this case, after setting the self-mode and memorizing it (step 313), the process proceeds to step 401 (shown in the fifth diagram) to charge the strobe. ,therefore,
If the camera is in standby mode and the selfie mode is set, charging of the strobe will start first, regardless of whether the strobe is being charged or not. Step 31
If the determination result in step 2 is No, the process returns to step 303 and the camera is placed on standby.

Figure 5 shows a flowchart of strobe control.
First, in step 401, it is determined based on the state of the main switch 2 whether the barrier is closed or not. Judgment result is Y
In the case of ES, that is, when the barrier is closed, there is no need to charge the strobe because photography is not performed when the barrier is closed, and the process proceeds to step 501 (shown in Figure 6).6 If the judgment result is No, the barrier is open and the step The process advances to step 402, where it is determined whether the S lock mode is in effect. If the result is YES, the shutter cannot be released and photographing cannot be performed, so there is no need to charge the flash, so the process returns to step 301 and enters the standby state. When the determination result in step 402 is No, charging of the strobe is started (step 403).

To start charging the strobe, the charge prohibition signal F inh sent from the port 1q of the CPUI becomes H to cancel the charge prohibition, and then the charge trigger signal Fct sent from the boat 1r changes from H to L. Therefore, the switching transistor 32f is turned on and the booster circuit 32
The voltage e begins to oscillate, is rectified by the diode 32h, and is charged to the main capacitor 31j.

Once charging has started, it is determined in step 404 whether or not there is a switch interruption. If the result is No, it is determined whether 30 seconds have passed since the start of charging (step 40).
5) If the charging period has not elapsed, it is determined in step 406 whether or not charging has been completed.

If the determination result is No, that is, if the battery is not charged, the process returns to step 404, and the determination of switch interruption (step 404) and the determination of 30 seconds elapsed (step 405) are repeated until charging is completed. If 30 seconds have passed during this repetition, it means that a problem has occurred such as insufficient voltage from the power supply battery 25, and in this case, a YES determination is made in step 405. Then, in step 407, charging is stopped, and in step 408, the charging completion mode is reset. In this case, the charge completion mode is reset because, as will be described later, when step 403 is reached, charging may have already been completed and the charge completion mode may have been set. After the charging completion mode is reset, the process proceeds to step 301.

When the determination result in step 406 is YES, that is, when charging is completed, charging is stopped (step 409), and the charging completion mode is set and memorized (step 4).
10), proceed to step 411.

When the main capacitor 32j is completely charged, a breakdown voltage is applied to the Zener diode 32k and a voltage is generated at the base of the switching transistor 321, so that the switching transistor 321 is turned on. Therefore, the charging end signal Fr changes from H to L, and the port 1t of CPU1
As a result, the charge trigger signal Fct changes from H to L, and the charging inhibition signal F inh changes from H to L.
The flash will stop charging.

In step 411, it is determined whether or not the self mode is set, and if the determination is YES, step 411 is performed.
2, it is determined whether one minute has elapsed. Note that during this one minute, for example, a light emitting diode or the like may be used to display that the device is in self mode. If one minute has not elapsed, the process proceeds to step 413, where it is determined whether there is a switch interruption. Further, after one minute has elapsed in step 412, the process proceeds to step 412a, resets the self mode, and then proceeds to step 413. That is, in step 412, the self mode is maintained for one minute after charging is completed.

If the determination result in step 413 is No, that is, if there is no switch interrupt, the process proceeds to step 414, where it is determined whether 5 minutes have passed since the charging completion mode was set, and it is determined whether 5 minutes have elapsed. If not, a negative determination is made and the process returns to step 411.

If 5 minutes have elapsed, that is, in step 414, Y
If it is determined to be ES, the process advances to step 415 and the charging completion mode is reset. That is, the charging completion mode is maintained for 5 minutes at step 414 after charging is completed.

Note that if 5 minutes elapse, there is a risk that the main capacitor 32j of the strobe will spontaneously discharge. If the charging completion mode is reset in step 415, the process returns to step 301 and enters a standby state in preparation for normal photographing.

If any switch is operated after the start of charging but before the completion of charging, a YES determination is made in step 404 and the process proceeds to step 416.

In step 416, it is determined whether the self-switch 16, which was in the OFF state, has been turned ON. If the result of this determination is YES, the process advances to step 417 and it is determined whether or not the self mode is set. This is 1. For example, the self-switch 16 is turned on in step 312 described above,
This is because if the self mode is stored in step 313, the self switch 16 will remain in the self mode even if it is turned off. In such a case, since the determination in step 417 is YES, the self mode is reset (step 418), and the process proceeds to step 405 to continue charging the strobe. That is, the self-switch 16 is
If the button is operated repeatedly, the second operation cancels self-timer photography. Also, step 417
If the determination result is NO, it means that the self-switch 16 was operated while not in the self-mode.
This is a case where self-timer photography is to be performed, and the process advances to step 419 to set the self-mode, and then returns to step 403 to start charging the strobe again.

If the determination in step 416 is No, the self-switch 16 has not been operated, so step 420
Then, it is determined whether the closed camera back has been opened. If the determination result in step 420 is YES, the process proceeds to step 421, resets the above-mentioned S lock mode, initial mode, F mode and 3S abnormal mode, which will be described later, and returns to step 405.

When the determination in step 420 is No, it means that there is no change in the state of the camera back switch 24, and it is determined which other switch has been operated. The other switches in this case are the first stage release switch 5, the wide switch 7, the tele switch 8, the main switch 2, or the rewind switch 21. When these switches are operated, the AF circuit 33 and motor 30 are driven, so if the strobe continues to be charged, the motor 30 etc. will not operate sufficiently due to the voltage drop of the power battery 25. First, step 42
Step 2 stops strobe charging.

Then, the process proceeds to step 423, and it is determined whether the first stage release switch 5 has been turned on. If this determination is YES, photographing is performed, so the process advances to step 601 and shutter processing is performed.

If the determination in step 423 is No, the process proceeds to step 424, where it is determined whether the tele switch 8 or the wide switch 7 has been turned on. If the result of the determination is YES, the process proceeds to step 501 to perform zoom processing, and if the result of the 0 determination is No, the self mode is reset in step 425. This means that the other operated switches are
Either the main switch 2 is operated in the direction of closing the barrier, or the rewind switch 21 is operated, so no photographing is performed in either case.
Self mode will be reset.

Then, in step 426, it is determined whether the main switch 2 is operated and the barrier is closed. If the judgment result is YES, it is necessary to move the photographing lens to a position where there is no problem in closing the barrier, so proceed to step 501 to perform zoom processing.If the judgment result is NO, proceed to step 427. , rewind switch 2
1 is ON or not. Regardless of whether the determination result in step 427 is YES or NO, step 70
Go to 1.

If no switch is operated during charging (if the determination in step 404 is NO), charging ends and the charging complete mode is maintained for 5 minutes (step 414) as described above. If any switch is operated, the determination in step 413 becomes YES and the process proceeds to step 428, where it is determined whether or not the self-switch 16 has been turned on.

If the result of this determination is YES, it is determined whether or not it is in the self mode (step 429), and if it is in the self mode, the self mode is reset (step 430).
), the process returns to step 414 and continues counting for 5 minutes. If the determination in step 429 is NO, the process advances to step 419, where the self mode is set, and then charging of the strobe is started (step 403). The time required for charging is extremely short.
If the determination result in step 428 is No, step 4
In step 31, it is determined whether or not the back cover has been opened. If the back cover has been opened, in step 432, F mode, S lock mode,
After resetting the 3S abnormal mode and initial mode,
Proceed to step 414. Further, when the determination result in step 431 is No, the process proceeds to step 423 described above, and the same determination as described above is performed.

Note that at this time, charging of the strobe has already been stopped (step 409), so step 422 is not passed.

FIG. 6 shows a flowchart of the zoom process for changing the focal length of the photographic lens. As described above, the process proceeds from steps 307, 308 or steps 401, 426, etc. to step 501, and the zoom process is performed.

In step 501, it is determined whether the main switch 2 has changed by being turned on or off.

At this time, if there is a change in the main switch 2, the process proceeds to step 502, where it is determined whether the main switch 2 is operated and the barrier is opened or closed. When the barrier opens, it means that you are about to take a picture, and after the barrier opens, you must move the stored photographic lens forward to a position where you can take pictures.

Further, when the barrier closes, it is a case where the camera is carried after the shooting is finished, and in this case, the photographing lens must be retreated to the storage position and the barrier must be closed. If the answer is No, the barrier is opened and the process proceeds to step 503. Immediately after filling the camera with the power battery 25,
As mentioned above, since the system is in the zoom system processing mode, YES is determined at step 301, and after the zoom system processing mode is reset at step 302, the process proceeds to step 502, where it is determined whether the barrier is open or closed based on the state of the main switch 2. Ru.

In step 503, the output of the encoder that detects the position of the photographic lens is set to the home position (HOME) or H.
In the camera shown in this embodiment, the photographing lens moves between the home position, the wide end position, and the telephoto end position.

The home position is a position further retreated from the wide end position, and is a position in which the barrier is retracted to close it. The focal length is changed by moving between the wide end position and the telephoto end position. Furthermore, Hl indicates the output of the encoder when the photographing lens is located between the home position and the wide end position.If the determination result in step 503 is No, the process advances to step 530, where the photographing lens moves forward. The processing in this case will be described later. If the determination result in step 503 is YES, it is impossible to take a picture even though the barrier is open, so the process proceeds to step 504, where the motor 30 for zooming is activated by a signal sent from port 1o of the CPU 1. Drive to move the photographing lens forward. Next, in step 505, wide switch 7 is turned on.
Determine whether or not. This is because the direction of rotation of the motor 30 is kept constant and the engagement state of the gear that transmits the rotation is changed to move the photographic lens forward or backward. If the wide switch 7 is turned on, the rotation of the motor 30 will be transmitted to move the photographic lens backward, so in order to check the meshing state of the gears, check the state of the wide switch 7. Check it out. Therefore, if the wide switch 7 is turned on and the determination in step 505 is YES, the motor 30 is stopped in step 507 in order to prevent the motor 30 from rotating any further and retracting the photographic lens. Further, even if the wide switch 7 is not ON, if the neutral switch 14 is ON, the transmission gear in this camera is in a state of engagement that causes the photographic lens to move backward, so in step 506 the neutral switch 14 is It is determined whether or not is turned on, and if YES, the motor 30 is stopped in step 507.

After the motor 30 has stopped, the wide switch 7
is turned on (step 508) and whether the neutral switch 14 is turned on (step 509). If either step 508 or step 509 is determined as YES, step 508
Return to That is, only when it is determined as No in both step 508 and step 509, that is, when both the wide switch 7 and the neutral switch 14 are OFF, the process proceeds to step 510, and the motor 30 is driven for zoom drive. The process then proceeds to step 511. Further, if the determination in step 506 is NO, that is, the wide switch 7 is not ON (step 505) and the neutral switch 14 is not ON (step 506).
), the process proceeds to step 511 with the motor 30 being driven in step 504.

In step 511, it is determined whether the barrier remains open. The judgment result is N.

When this is the case, that is, when the barrier is open, the process proceeds to step 512, where it is determined whether the encoder is at the Hl or home position. When the determination result in step 512 is YES, the process proceeds to step 513 with the motor 30 continuing to rotate, and it is determined whether two seconds have elapsed. 2
Before the second elapses, the determination in step 513 becomes No, and the process returns to step 505.

If the determination in step 511 is YES, the barrier is closed and photographing is not performed, so the process proceeds to step 514 and the motor 30 is stopped.

If the determination result in step 512 is No, that is, if the encoder no longer indicates the HL or home position, the photographing lens has moved forward to the photographing position, so the process advances to step 514 and the motor 30 is stopped. Furthermore, if the determination in step 513 is YES, the encoder continues to indicate Ho and the home position even though 2 seconds have passed, and there may be some abnormality such as the photographic lens not moving. After proceeding to step 514 and stopping the motor 30, proceeding to step 515 to determine whether the barrier is closed. If the determination result in step 515 is No, that is, if the barrier is open, the process proceeds to step 401 and the strobe is charged in preparation for release. If the determination result in step 515 is YES, that is, if the barrier is closed, the process returns to step 502 because it is necessary to retreat the photographic lens to the storage position.

If it is determined in step 502 that the barrier is closed based on the state of the main switch 2, the process proceeds to step 516.
If YES is determined in step 502, the barrier is closed, so the photographing lens must be in the retracted position, and in step 516 it is determined whether the photographing lens is in the retracted position, that is, the encoder is in the home position. It is determined whether or not. When this determination result is No, the motor 30 is driven to move the photographing lens backward (step 517). Furthermore, when the main switch 2 is operated in the direction to close the barrier, the main switch 2 is Since the mechanical structure is such that the wide switch 7 is turned on in accordance with the operation, the states of the wide switch 7 and the neutral switch 14 are checked as in steps 505 and 506 described above to drive the motor 30. There's no need to. Then, while the motor 30 is rotating, it is determined in step 518 whether or not the main switch 2 is maintained in a state where the barrier is open. If the determination result is No, the barrier is maintained closed. ,
In step 519, it is determined whether the encoder indicates the home position. If this determination is No, the process advances to step 520, and it is determined whether two seconds have elapsed. 2
If the second has not yet elapsed, the process returns to step 518. If the determination in step 518 is YES, the barrier has been opened, so the process proceeds to step 521 and the motor 30 is stopped. Further, when the determination in step 519 is YES, since the encoder has instructed the home position, the process advances to step 521 and the motor 30 is
stop. Also.

If YES is determined in step 520, this means that the encoder does not indicate the home position even after 2 seconds have passed, and there may be some abnormality, so step 5
Proceed to step 21 to stop the motor 30.

After stopping the motor 30, the process proceeds to step 522, where it is determined whether the main switch 2 is not maintained and the barrier is opened. If this determination is YES, the barrier has been opened, so the process returns to step 502 and proceeds from step 502 to step 503, where the process of advancing the photographing lens to the photographing position as described above is performed. If the determination result in step 522 is No, the barrier is closed and the camera waits for photographing, so the process returns to step 301 and enters the standby state.

If it is determined in step 501 that there is no change in No. 1, that is, there is no change in the main switch 2, the process proceeds to step 523, where it is determined whether the main switch 2 is in a state where the barrier is closed or whether the main switch 2 is in the S lock mode.

If the determination result is YES, it means that the barrier is closed or the shutter is locked, and the camera is not in a state for photographing, so there is no need to move the photographic lens, and the process returns to step 301 to enter the standby state. If the determination in step 523 is No, the barrier is open and the shutter is not locked, so it is ready for photographing, so the process proceeds to step 524, where it is determined whether the wide switch 7 is turned on. . In this case, in order to take a picture, the photographer is trying to determine the composition by visually checking the subject through the finder.

If the determination result in step 524 is YES, it is necessary to position the photographing lens at the photographing position.

Therefore, the process proceeds to step 525, and it is determined whether the encoder is at the wide end (W end), Hl, or home position. Note that if the photographic lens is in the retracted position, the photographer will operate the tele switch 8 without operating the wide switch 7, so the determination result in step 524 will be No and the process will proceed to step 526. become.

When the determination result in step 525 is No, the photographing lens is already in a forward state, so the zoom motor 3 is
0 is driven (step 527). If the motor 30 is driven, the process proceeds to step 528, where it is determined whether the main switch 2 is in the open state of the barrier. If the barrier is in an open state, the determination result in step 528 is NO.
Then, the process advances to step 529. In step 529, it is determined whether the wide switch 7 is maintained in the ON state. If YES, the process proceeds to step 531, and it is determined whether the encoder instruction is Hl or the home position.

If the result of this determination is NO, the process proceeds to step 533, where it is determined whether or not two seconds have elapsed.If not, the result of the determination is NO, and the process returns to step 528, where the determination process is performed in the same way. The determination result in step 528 is No.
If this occurs, that is, if the main switch 2 is operated to close the barrier, the process proceeds to step 518 with the motor 30 continuing to rotate, and the motor 30 is rotated until the photographic lens is retracted to the storage position. It will be processed as follows.

When it is determined No in step 529, that is, when the wide switch 7 is turned off, the process proceeds to step 530, where the photographing lens is slightly advanced and the motor 3 is turned on.
Processing to stop 0 is performed.

This is because when the motor 30 rotates in step 527, the photographic lens is moved backward, but if the motor 30 is stopped while the motor 30 is in the backward state, each transmission gear meshes with the tooth side on the side that causes the photographic lens to move backward. are doing. When the gears mesh, there is backlash, and when the motor 30 is then driven to move the photographic lens forward, the motor 30 is driven until each transmission gear meshes with the tooth side on the side that advances the photographic lens. A situation arises in which the rotation is not transmitted to the photographic lens. For this reason, each gear is rotated in advance by an amount corresponding to the backlash so that when the photographing lens is next moved forward, the photographing lens moves forward almost at the same time as the motor 30 starts rotating.

Then, when the determination in step 531 is YES, that is, when the encoder is in the H position or the home position, the motor 30 is stopped (step 532), and the process proceeds to step 508, where the motor 30 is driven again ( Step 510), the photographing lens is advanced until the encoder no longer indicates H□ or the home position (step 512), that is, the motor 30 is rotated until the photographing is possible. In this case, since the photographing lens moves forward from the storage position or the H1 position, there is no need to perform processing regarding the backlash of the transmission gear.

Also, the determination result in step 503 described above is NO.
, that is, the main switch 2 is operated (step 501) and the barrier is opened (step 502).
In step 530, if the encoder is not in either the Hl or home position, the process proceeds to step 530, and the motor 3
0 is slightly rotated to move the photographing lens forward.

Then, when the determination result at step 525 is YES, that is, when the wide switch 7 is turned on (step 5
When the encoder is at the W end, H position, or home position in step 24), or when the process of step 530 is completed, the process proceeds to step 535. Also,
If the determination in step 533 is No, this means that the encoder does not indicate either Hl or the home position even though the motor 30 rotates for 2 seconds, so it is determined that there is some abnormality and the motor 30 is stopped (step 534). , the process proceeds to step 535. In step 535, it is determined whether the barrier is closed based on the state of the main switch 2, and if YES, the process proceeds to step 516 and the process continues until the encoder indicates the home position (
Step 519) Rotate the motor 30 (Step 5
17). If the determination result in step 535 is No, the barrier is open and the process proceeds to step 401 to charge the strobe.

If the determination in step 524 is No, the photographer looks at the subject through the finder and operates the teleswitch 8 to determine the composition. In this case, as described above, the process proceeds to step 526, and it is determined whether or not the encoder is indicating the tele end (W end).
If the result is YES, there is no need to drive the motor 30, so the process proceeds to step 535 and is processed as described above.

When the determination in step 526 is NO, the motor 30 is driven to advance the photographing lens (step 537), and the process proceeds to step 538, where it is determined whether the main switch 2 has been operated to close the barrier. . When this determination result is No, it is determined whether or not the teleswitch 8 is maintained ON (step 539). When YES is determined in step 539, the teleswitch 8 is turned on, and step 540
It is determined whether or not the encoder has designated the T end. If the result is NO, it is determined whether two seconds have elapsed. If not, the process returns to step 538.

If the determination in step 538 is YES, that is, if the barrier is closed, there is no need to move the photographic lens forward, so the motor 30 is stopped (step 542) and the process proceeds to step 535. In this case, the determination result in step 535 is YES, so the process proceeds to step 516, where the motor 30 is driven again and the photographing lens is moved backward until the encoder indicates the home position (step 519).
), if the determination in step 539 is NO, then the teleswitch 8 has been turned off, so the motor 30 is stopped (step 542), and the process proceeds to step 53.
Proceed to step 5 to determine whether the barrier is open or closed. Step 540
If it is determined to be YES, the photographic lens has moved forward and the encoder has indicated the T end, and since the photographic lens cannot be advanced any further, the motor 30 is stopped (step 542) and the process proceeds to step 535. Furthermore, if the determination is YES in step 541, the photographing lens will not advance to the T end even after 2 seconds have elapsed.
If it is determined that there is some abnormality, the process proceeds to step 542 where the motor 30 is stopped, and then the process proceeds to step 535.
If the determination result in step 535 is No, that is, if the barrier is open, the process proceeds to step 401 and the strobe is charged in preparation for release.

Figure 7 is a flowchart of shutter processing. For example, when the camera is in standby mode or during strobe control,
When the release button is pressed and the first stage release switch 5 is turned on (steps 309 and 423), the process proceeds to step 601 and shutter processing is performed.

In step 601, it is determined whether or not the S lock mode is in effect. If the determination is YES and the S lock mode is in effect, the shutter cannot be released, and step 60
Proceed to step 2, N at step 601.

If it is determined that the shutter is not locked, the process proceeds to step 604, where it is determined whether the encoder indicates Hl or the home position.

If it is determined as YES, the shutter cannot be released because the photographing lens has not moved forward at Wt- enough to take a photograph, and the process proceeds to step 602. If the determination result in step 604 is NO, the process proceeds to step 605. A battery check is performed to determine if there is sufficient voltage. If the result of this determination is NO, sufficient voltage is not obtained to perform a release after measuring the distance to the subject, so the process proceeds to step 602 without performing any subsequent processing.

In step 602, it is determined whether the first stage release switch 5 is turned on, and if YES, the determination in step 602 is repeated. When the finger is removed from the release button and the first stage release switch 5 is turned OFF, the determination result in step 6020 becomes No, and the process proceeds to step 603, where the shutter and AF system signals are released, and the process proceeds to step 301, where the camera is turned off. It goes into standby mode.

If YES is determined in step 605, photometry is performed to control the exposure during shooting and the data is stored (step 606).Then, the process advances to step 607 and the data obtained in step 606 is used. Based on this, it is determined whether the attached strobe needs to emit light, that is, whether the light emitting mode has been selected, and whether the strobe is uncharged.

If the result of this determination is No, the exposure is possible, so the process proceeds to step 608, where the subject distance is measured and stored. Then, the process proceeds to step 609, where it is determined whether or not strobe photography is to be performed based on the data in step 606, that is, whether or not the flash mode is in effect.If the result is YES, the process proceeds to step 610, where the distance data in step 608 is used. Based on this, calculations for strobe light emission by Flashmatic are performed to determine the aperture value, and the process proceeds to step 611. Also, step 60
If the determination result in step 9 is No, there is no need to emit light from the strobe, so the process advances to step 611.

In step 611, it is determined whether the release button has been completely pressed down and the second stage release switch 6 (SF3) has been turned on. This judgment result is N.

If so, in step 612 the first stage release switch 5 is
If the determination is YES, the process returns to step 611 and this process is repeated until the second stage release switch 6 is turned on. If YES is determined in step 611, the process proceeds to step 613, where it is determined whether or not the self mode is set. If the result of this 6 judgment is NO1, that is, it is not in self mode, step 61
4, the lens stage is set based on the distance data obtained in step 608, and the film is exposed (
step 615). Then, the shooting date is imprinted on the film frame as necessary (step 616).
Afterwards, the lens is returned to its initial position (step 617).
), shooting ends. Thereafter, in step 618, the shutter and AF system signals are released, and when flash photography is performed, the charging complete mode is reset at the same time.

In step 619, it is determined whether it is in the initial mode,
When the determination result is YES, the process proceeds to step 1101 (shown in the twelfth figure), and when the result is No, the process proceeds to step 620. In step 620, it is determined whether or not the F mode is in effect. If YES, the process proceeds to step 701; if NO, the process proceeds to step 410 to charge the strobe.

When the determination result in step 613 is YES, it means that the self mode is selected, and in this case, the process advances to step 621. In step 621, main switch 2
It is determined whether the open barrier is closed based on the change in , and if No, the process proceeds to step 622 and it is determined whether the self-switch 16 has been turned on. When the result of this determination is No, a change in the back cover switch 24 is detected and it is determined whether the closed back cover is opened (step 623). If the determination result in step 623 is No, the process advances to step 625 and the second stage release switch 6
Determine whether 10 seconds have passed since the was turned on,
If 10 seconds have not elapsed, the process returns to step 621 and the above process is repeated; if 10 seconds have elapsed, the process returns to step 6.
The process advances to step 14 and exposure is performed. Namely.

In the self mode, the release button is released after 10 seconds have elapsed since the release button was completely pressed down. Further, when the determination in step 623 is YES, since the camera back has been opened, the process proceeds to step 624, resets the F mode, S lock mode, 3S abnormal mode, and initial mode, and proceeds to step 625.

Furthermore, if the determination in step 607 above is YES, the flash is not sufficiently charged even though it is in the flash mode and must be used for flash photography, making it impossible to perform proper exposure at the time of release. The shutter and AF system signals are canceled (step 626).
). If the determination result in step 612 is NO, the shutter and AF system signals are canceled in step 626, since the finger has been removed from the release button and photographing will not be performed. If YES is determined in step 621, the barrier is closed, and the process proceeds to step 626.

Further, if a YES determination is made in step 622, in the state of self mode (step 613
) Since the self-mode is canceled because the self-switch 16 is operated, the release is canceled and the process proceeds to step 626, followed by step 41 to charge the strobe.
Go to 0.

FIG. 8 shows a flowchart for determining what state the camera mode is in, selecting and branching the process corresponding to that state, and determining in step 311 that the camera is not in S lock mode. If so, step 42
If the state of the rewind switch 21 is determined in step 7, or if it is determined that the F mode is in step 620, the process proceeds to step 701 and branch processing is performed.

In step 701, it is determined based on the state of the main switch 2 whether or not the back cover is open. If the result is YES, the camera back is opened and cannot be used for photography, so in step 702 F mode, S lock mode, 3S
After resetting the abnormal mode and the initial mode, the process proceeds to step 401. If the determination result in step 701 is NO, the process proceeds to step 703, where it is determined whether or not the erroneous opening/closing mode, which will be described later, is present. If the result of this determination is YES, the erroneous opening/closing mode is reset (step 704), and the process proceeds to step 705, where it is determined whether the rewind switch 21 is turned on. If the determination in step 705 is No, the process proceeds to step 1201, where processing in the case of erroneous opening/closing is performed. Also, the determination result in step 705 is YE.
When it is S, the rewind switch 21 is ON and the film will be rewound, so the process advances to step 706 and the motor 30 is turned on for film feeding (MF).
to drive. Even when the determination result in step 703 is No, the process proceeds to step 706 and the motor 30 is driven. Then, in step 707, it is determined whether the mode is F mode. If this judgment is YES, 1 of the film
The process advances to step 901 to advance frame by frame.

If the determination result in step 707 is No, the process advances to step 708 and it is determined whether the rewind switch 21 is turned on. In step 427 described above, it was determined whether the rewind switch 21 was ON or not, and the process proceeded to step 701 regardless of the result, but step 708
Then, it is determined again whether the rewind switch 2] is ON or not, and the subsequent processing will be different depending on the result.

That is, when the determination result in step 708 is YES, step 100 is performed to rewind the film.
1 (FIG. 11), and if No, the process advances to step 801 (FIG. 9) to check the presence of the film.

Figure 9 shows whether the film is loaded or not, and if it is loaded, if it is the initial loading, the leader of the film is wound up and the first frame is set to the aperture. (FFS) processing flowchart. When proceeding to step 801, the motor 30 is rotating (step 706).

First, in step 801, it is determined whether the rewind switch 21 is turned on. If this is YES, the film is rewound, so the process does not proceed to FFS processing but proceeds to step 1001, step 80.
1 is No, the process advances to step 802 and it is determined from the state of the back cover switch 24 whether or not the back cover is open. If this judgment result is YES, the film is
Since there is nothing to do, the motor 30 is stopped in step 803, and then the process proceeds to step 301 to put the camera in standby mode.

If the determination result in step 802 is NO, since the camera back is closed, the process proceeds to step 804, where FFS processing is performed, and it is determined whether or not it has been completed. FFS counts the perforations of the film; for example, if the film is wound one frame, it is S. If a signal is received and the reader section winds up four frames, FFS ends when four S0 signals are received. Step 804
If the result of the determination is NO, the process advances to step 805, where it is determined whether 5 seconds have elapsed. If 5 seconds have not elapsed, the process returns to step 801, and the above-described process is repeated.

Further, if the FFS does not end even after 5 seconds have elapsed, that is, if the determination in step 805 is YES, the motor 30 is stopped because the film is not loaded (step 806).

If the FFS is completed, the determination in step 804 becomes YES and the process proceeds to step 807.

In step 807, F mode is set and stored. F mode is a mode that indicates that the film is loaded and shooting continues, so it is set when the film is released and the exposure is completed (step 620), or when the film is advanced one frame in step 707, etc. has been done. If the F mode is set, the motor 30 is stopped (step 806), and the process proceeds to step 301 to put the camera in standby mode.

Figure 10 is a flowchart for advancing the film one frame. When the camera is determined to be in F mode,
That is, when the final determination in step 707 is YES, one frame advance is performed. Note that when the process proceeds to step 901, the motor 30 is already rotating (step 706).

In step 901, it is determined whether or not the rewind switch 21 is turned on. If YES, the film is completely wound, so no frame advance is performed, and the F mode is reset (step 902). Step 1001 for rewinding the film
Proceed to. If the determination in step 901 is No, then it is determined whether or not the back cover is open (step 903).

If the determination result is YES, reset the F mode, S lock mode, 3S abnormal mode, and initial mode (step 904), stop the motor 30 (step 905), and then proceed to step 301 to prepare for the next process. .

Then, when the determination in step 903 is No,
In step 906, one frame forwarding (F processing) is performed and it is determined whether or not it is completed. It is determined that one-frame forwarding is completed by detecting the S signal described above. If the determination in step 906 is No,
In step 007, it is determined whether 3 seconds have elapsed,
If No, the process returns to step 901 and the above process is repeated.

When it is determined YES in step 906, that is, when one frame forwarding is completed, the process advances to step 908 and the 3S
The abnormal mode is reset and the motor 30 is stopped (step 911).

Moreover, when it is determined as YES in step 907,
Even though 3 seconds have passed since the 1-frame advance was started, the 1-frame advance is not completed, and it is determined that there is some kind of abnormality, so the 3S abnormal mode is set and the number of times this is set is counted. (Step 909) Next, the process proceeds to Step 910 to determine whether or not the 3S abnormal mode has been counted five times. If the result is No,
Motor 30 in the same way as when 3S abnormal mode is set.
In step 911), the process proceeds to step 912, where it is determined whether the rewind switch 21 is turned on. If this determination is YES, the film is completely wound up, its torque is detected, and the rewinding switch 21 is turned on. And step 912
If it is determined to be YES, the film will not be advanced one frame after that, so reset the F mode.Step 9
13) Proceed to step 701 to branch the subsequent processing. If the determination in step 912 is NO, the process advances to step 401 and the strobe is charged in order to wind the film one frame and wait for the next photograph.

Further, when the 38 abnormal mode is counted five times in step 910 and the determination result is YES.

The motor 30 is stopped (step 914), the F mode is reset to prevent further frame advance (step 915), and the S lock mode is set to prevent release (step 91).
6) Proceed to step 301 and put the camera on standby in preparation for the next process.

FIG. 11 is a flowchart showing a process for rewinding the film when all frames of the film have been photographed. As mentioned above, the processing before rewinding is
Step 211. There are step 708, step 801, step 902, etc. Step 211 is a case where the power supply battery 25 is replaced because it is exhausted during the winding of the film. Step 708, Step 801
In step 902, the film is completely wound and the rewind switch 21 is turned on. Further, when the process proceeds to step 1001, the motor 30 is already rotating.

In step 1001, it is determined from the state of the 7A lid switch 24 whether or not the back lid is open. This judgment result is Y
When ES occurs, the camera back is accidentally opened while the motor 30 is rotating and the film is being rewound. Therefore, the erroneous opening/closing mode must be set (step 1002), and then the motor 30 is stopped (step 1003). ), proceed to step 301. Also, in step 1001, the result is N.

If it is determined that this is the case, the process proceeds to step 1004, where it is determined whether or not 80 signals obtained from the above-mentioned film perforations have been received within 3 seconds.

If 80 signals are received before 3 seconds have elapsed, the determination result in step 1004 becomes No, and the process proceeds to step 100.
Return to 1. That is, if a change in the S0 signal is detected and continues to be detected, the film rewind process is continued. Then, the determination result in step 1004 is Y.
If the 80 signal is not received even after 3 seconds have elapsed since ES, the film is completely rewound and the remoter 30 is stopped (step 1005), and the S
The lock mode is set (step 1006) and the process proceeds to step 301.

FIG. 12 shows a flowchart of the process performed when replacing the power battery 25 when the initial mode is set. That is, in step 619, YE
This process is performed when the determination S is made, but the initial mode is set in step 209, which is when the power source battery 25 is charged. Therefore, for example, this process is performed by replacing the power supply battery 25 with the film loaded and releasing the camera.

In step 1101, the initial mode set in step 209 is reset so that this process will not be performed when the camera is released thereafter. Next, the motor 30 is driven for film feeding (step 1102), and the process proceeds to step 1103. In step 1103, it is determined whether the rewind switch 21 has been turned on.

If YES, the process proceeds to step 1001 since the film is to be rewound. If the determination result in step 1.103 is No, the process proceeds to step 1104, where it is determined from the state of the IA lid switch 24 whether or not the back cover is open. If YES, the program 30 is stopped (step 1105).

Proceeding to step 301, the camera is placed on standby in preparation for the next process. When the determination result in step 1104 is No, the process proceeds to step 1106, and the presence or absence of the 80 signal described above is determined. This judgment takes a predetermined time (3s
ec,), and it is determined whether 3 seconds or more have elapsed until the 80 signal changes. If the 80 signal is received before 3 seconds have elapsed, the camera is loaded with film, so the determination result in step 1106 is No, and the process advances to step 1107 to advance one frame. In step 1107, it is determined whether or not the one-frame forwarding process has been completed. If the result of this determination is NO, the process returns to step 1103, and the above-mentioned process is repeated until one frame is advanced.

If the determination in step 1107 is YES and one frame has been sent, the motor 30 is stopped.
8), proceed to step 1109. In step 1109, it is determined whether or not the rewind switch 21 has been turned on. If this is YES, step 70 is performed to proceed to the next process.
Go to 1. Further, if the determination result in step 1109 is No, the power battery 25 will be replaced while the film is being loaded, one frame advance will be completed, and the next shooting will be on standby, so the F mode is set (1110). L, the process proceeds to step 401 to charge the strobe.

If the determination in step 1106 is YES, the film has not been advanced by one frame even after 3 seconds have elapsed, indicating that the film is not loaded or that there is some abnormality. In this case, the process proceeds to step 301 without setting the F mode.

FIG. 13 shows a flowchart of the erroneous opening/closing process. If the back cover is opened by mistake while rewinding the film (YES is determined in step 1001, and the erroneous opening/closing mode is set in step 1002). ). Note that when the back cover is opened, the rewind switch 21 is mechanically turned off in conjunction with the opening. At this time, since the motor 30 is in a stopped state (step 1003), the motor 30 is driven to feed the film at the step 1201, and the film is wound up.

Then, it is determined whether or not the rewind switch 21 is turned on (step 1202), and if YES, the process proceeds to step 1001 to rewind the film.
Since the rewind switch 21 is turned off as described above, the determination result in step 1202 is No, and the process proceeds to step 1203, where it is determined whether or not the camera back is open. Generally, if the back cover is opened by mistake, the back cover will be closed immediately, so the determination result in step 12030 is No.
Therefore, the process proceeds to step 1204, where it is determined whether 3 seconds have elapsed. This 3-second determination is made based on the presence or absence of the signal S indicating one frame of the film described above.

If the determination result is No, that is, 3 seconds have not elapsed until the next S signal is received, step 1202
The process returns to , and the above process is repeated. Then, when the film is completely wound up, the torque is detected and the rewinding switch 21 is turned on.
The determination result in step 2 is YES, and the process moves on to rewinding the film. That is, if the back cover is opened by mistake while the film is being rewound, the film must be completely rewound and then the rewound process is performed again.

Further, when the determination in step 1203 is YES, that is, when the camera back is opened again, the erroneous opening/closing mode is set (step 1205) and the motor 30 is stopped (step 1206). When the result is YES, that is, when the 80 signal is not received even though 3 seconds have elapsed, the process advances to step 1206 to stop the motor 30 and step 30 in preparation for the next process.
Proceed to step 1 to put the camera on standby.

Note that the reset of the erroneous opening/closing mode is performed through the following process. As described above, the erroneous opening/closing mode is set in step 1002, the motor 30 is stopped (step 1003), and the process proceeds to step 301, where the camera enters the standby state. Then, when the accidentally opened back cover is closed, the process proceeds from step 310 to step 311, and since the S lock mode is not set at this time, the process proceeds to step 701. Then, in step 703, it is determined that the erroneous opening/closing mode is in effect, and the process proceeds to step 704, where the erroneous opening/closing mode is reset.

FIG. 14 shows a flowchart of the process performed to wait for the next operation when the film is fully rewound.
When the S lock mode is set in step 06 and the back cover is opened to take out the film, YES is determined in step 310, and YES is determined in step 311, so the process proceeds to step 1301 and performs the processing shown in this flowchart. .

In step 1301, it is determined whether the rewind switch 21 is turned on, and if YES, step 13
Proceed to step 02 to determine whether the camera back is open or not. If the result of this determination is No, the process advances to step 301 and the camera is placed in standby mode in preparation for the next process.

Further, when the determination result in step 1302 is YES, the process returns to step 1301 and the rewind switch 21 is turned OFF.
Step 1 until F is pressed or the back cover is closed.
The processes of steps 301 and 1302 are repeated.

If the determination in step 1301 is NO, that is, if the rewind switch 21 is turned off, the motor 30
is driven for zooming (step 1303), 300m5
After driving during EC (step 1304), the motor 30
(step 1305), thus motor 3
The reason why the 0 is rotated slightly is that at the end of the rewinding process, the transmission gear is engaged with the rewinding side in the film feeding system, and in the next process, the film will be wound up, the photographic lens will be driven, etc. This is to prepare the meshing state of the transmission gear for the next process.

Then, in step 1306, the F mode, S lock mode, and 3S abnormal mode are reset, and the process proceeds to step 401 to charge the strobe.

It operates as described above, but the processing when the selfie mode is set is at step 313 and step 419, and when the camera is being used for shooting and the selfie mode is set, the process always proceeds to step 403. This will start charging the strobe.

〔Effect of the invention〕

As explained above, according to the camera with a strobe according to the present invention, when the self-timer switch is operated to perform self-timer photography, the self-mode is set and the process of forcibly charging the main capacitor of the strobe is performed. . Further, when the light emission mode is set based on photometric data and the flash is not charged, it is possible to disable the release. Therefore, when photographing in self-mode and the strobe must fire, there is no need to confirm that the strobe is fully charged, and the strobe fires in conjunction with the release, allowing proper exposure.

Therefore, it is possible to prevent failures in photographing or missing photo opportunities as much as possible.
