The shutter validity determination circuit 173 includes a second remote controller operation unit 610.
A gate circuit that determines whether or not to release the release signal that is input when the release button 611 of is pressed. In addition to the above-mentioned charge completion signal, the micro switch 190 for magazine mounting determination (ON when the magazine 4 is mounted) become),
All the discrimination signals from the magazine state discrimination circuit 184 (“1” if there is a film, “0” if there is no film) and the above-mentioned signals from the video signal freeze circuit 160 (normally “0” during freeze) are all The release signal is enabled and output only when it is ON or "1".

When this valid release signal is input to the flickering timer circuit 174, the timer and flickering signal generator are activated and the line-of-sight guidance lamp (LED) is activated for a predetermined time (for example, 0.5 seconds).
After blinking 104 (intermittent lighting), the timer inputs the time-up signal to the video freeze circuit 160 and also inputs it to the shutter solenoid drive circuit 176.

The video signal freeze circuit 160 freezes the video signal of the immediately preceding one frame by the input of the time-up signal and causes the monitor television 140 to continuously display a still image (still image) by the video signal as described above.

On the other hand, the shutter solenoid drive circuit 176 is activated immediately after that to drive the shutter solenoid 177. As a result, when the shutter 18 opens and the photo switch 191 detects it, the electronic flash (EF) 511-514 is detected.
Then, the still camera 150 emits a synchronizing signal to emit light simultaneously, and the still camera 150 shoots the film F.

Then, when the shutter 18 is closed, the photo switch 192 detects it and sends a signal to the winding motor drive circuit 178, the circuit 178 is activated and the winding motor 151 is rotated,
The film F in the magazine 4 is wound by one frame, and the motor 151
At the origin position of, the micro switch 455 (see Fig. 10) is turned on.

The magazine count pulse generation circuit 182 generates a count pulse in response to the signal, turns on the LED 193 in a pulsed manner, and transmits the signal to the magazine 4 side. At the same time, the effective photographing count determination circuit 183 outputs a pulse during effective photographing, and counts up one each of the photo counter (electronic counter) 116 and the total integration counter (mechanical counter that cannot be reset) 119.

This completes a series of shooting operations, and the timing relationship of each signal during that time is shown in the timing chart of FIG.

When a valid shutter release signal is output from the shutter valid judging circuit 173, the data copying circuit 186 operates to turn on the data copying lamp (LED) 187, and the information card insertion hole 1366 shown in FIG. Information card 21 inserted in
(Information for identifying the person to be the subject is recorded by a barcode or the like) is illuminated, and the information is photographed on the side portion of the film F outside the screen.

In addition, another LE (not shown) that indicates the number of times the same subject is shot
The number of D's is turned on for the number of times and the images are directly photographed on the film F at the same time.

Next, to release the magazine 4, the hook release button 13
The operation when 4 is pressed will be described.

When the hook release button 134 is pressed, the switch signal that is turned on by the depression is input to the dummy feed control circuit 179. At this time, if the micro switch 190 is off (without magazine), the control circuit 179 does not output an output signal, but if on (with magazine), it outputs an output signal and resets the dummy feed counter 180 at the rising edge. At the same time, the winding motor drive circuit 178 is operated to wind up the film in the magazine 4, the gate of the effective photographing count determination circuit 183 is closed, and the counters 116 and 119 are not counted up even if the signal from the micro switch 455 is input. To do so.

The micro switch 455 is turned on every time the film is wound by one frame by the rotation of the motor 151, and the dummy feed counter 180 counts the signal, and when the count value reaches a predetermined number, for example, "3", the count up Output a signal.

The count-up signal is the dummy feed control circuit 179.
When the input signal is input to, the circuit 179 does not output a signal and the operation of the hoisting motor drive circuit 178 is stopped.

At the same time, the magazine lock release solenoid drive circuit 181 is activated by this count up signal to drive the magazine lock release solenoid 444. Accordingly, the hook 441 shown in FIGS. 9 and 10 is rotated, and the lock of the magazine 4 is released.

Therefore, when the magazine 4 is taken out, the micro switch
190 is turned off, the signal stops the operation of the magazine lock release solenoid drive circuit 181, and the solenoid 4
Turn off the power to 44. Therefore, the hook 441 is returned to the lock position by the biasing force of the spring. When the micro switch 190 is off, the warning lamp 113 not loaded with the magazine is turned on.

In this way, when the magazine 4 is taken out, even if the hook release button 134 is pressed, the film can be automatically wound up by three frames and then taken out, so that the taken frames can be taken out while being exposed at the aperture part. Instead, it is safe when the magazine 4 is taken out during use of the film and only the photographed portion is to be cut and developed.

Also, when the magazine 4 is loaded, the micro switch
When the 190 is turned on, the dummy feed control circuit 179 operates at this rising edge, and the film winding for three frames is automatically performed in the same manner as in the above-mentioned case, and the film portion which is not exposed at all. Set to the aperture position and stop. However, in this case, the magazine lock release solenoid drive circuit 181 is prohibited from operating by the rising signal of the micro switch 190, and the dummy feed counter
It does not work even if the count-up signal from 180 is input.

Even when these films are wound (idle feed), the magazine counter pulse generation circuit 182 generates a count pulse by the ON signal of the micro switch 455, and the LED 193
Is turned on and the signal is sent to the magazine 4 side.

In this embodiment, as shown in FIG. 9, FIG. 10 and FIG. 17, the micro switch 190 is set to the magazine mounting detecting means, and the film magazine in which the hook 441 and the spring 443 are mounted to the main body 1 is set to four mounting states. The lock means for locking, the hook release button 134 is the lock release instruction means, the magazine lock release solenoid drive circuit 181 and the magazine lock release solenoid 444 are the lock release means.

Further, the dummy feed control circuit 179, the dummy feed counter 181, the winding motor drive circuit 178, the winding motor 15
1 and the micro switch 455 and the like constitute automatic feed means.

Next, the circuit in the film magazine 4 will be described.

The magazine 4 is provided with a subtraction type electronic counter (hereinafter referred to as “subtraction counter”) 460 and respective circuits related thereto, all of which are powered by a built-in battery 461 to operate.

The subtraction counter 460 is reset to a predetermined initial value, for example, "903", when a new film is loaded and when the manual reset button 462 is pressed. The count value of the counter 460 is 3 when the display button 407 shown in FIG. 7 is pressed and the display switch 407S is turned on.
It is displayed on the display unit 406 by the digit LED.

463 is a micro switch for detecting the opening / closing of the lid which is operated by the pin 418 shown in FIG. 8 and is turned on when the lid 420 of FIG. 8 is closed and the fixing screw 421 of FIG. 7 is tightened. ,
It is turned off when the lid 420 is opened.

464 is a ring magnet fixed to a shaft coaxial with or interlocking with the sprocket 413 on the supply side in FIG.
N-poles and S-poles are alternately magnetized on the outer periphery, and when rotated, the lead switch 465 arranged in proximity to this is turned on / off.

The ON / OFF signals of the micro switch 463 and the read switch 465 are input to the film presence / absence detection circuit 466 and the film loading detection circuit 467.

On the other hand, when the phototransistor 469 receives the light emission of the LED 193 on the main body side through the through hole 403, the count pulse receiving circuit 468 receives the detection signal and inputs the phototransistor 470.
If the external light from the through hole 405 is not detected, a count pulse is generated and the subtraction counter 460 is decremented by "-".
1 ”.

The film presence / absence detection circuit 466 winds the film when the count pulse is input from the count pulse reception circuit 468 when the micro switch 463 is on and the lead switch 464 is on or off (the ring magnet 464 does not rotate). Although the operation is performed, since the sprocket 413 does not rotate, it is determined that there is no film and a single pulse is output.

When this pulse is input to the magazine status transmission circuit 471, L
The ED472 is turned on once for a short time to notify the main body 1 side that there is no film.

When the magazine state determination circuit 184 on the main body 1 side determines that, the warning lamp 115 without a film is turned on, and
Alarm buzzer 112 with a relatively long cycle (beep)
It makes a sound to inform it and sends an invalid signal to the shutter valid judging circuit 173.

The film loading detection circuit 467 determines that film loading is in progress when the micro switch 463 is off and the lead switch 465 is repeatedly turned on and off, and when the micro switch 463 is turned on thereafter (the lid 420 is closed). A film loading completion signal is output.

When this signal is input to the dummy pulse generation circuit 473, a predetermined number of dummy pulses (4 pulses in this example) are generated and the subtraction counter 460 is subtracted by that number of pulses. This is to reduce the number of film frames required for film loading from the remaining amount of film.

In addition, the film loading detection circuit 467 is a film absence detection signal (single pulse) from the film presence / absence detection circuit 466.
Will be remembered when is input, then the microswitch
When the ON / OFF signal of the lead switch 465 is input after the 463 is turned off, it is determined that a new film is loaded in the film magazine 4, and the reset signal is output.
The subtraction counter 460 is reset to the initial value (“903” in this example).

After that, the lid 420 of the film magazine 4 is closed,
When the micro switch 463 is turned on, a film loading completion signal is output in the same manner as in the above case, and the counter 460 is decremented by "4" (in this example, "899").
To).

The counter clear circuit 474 generates a clear pulse and clears the subtraction counter 460 to “000” when a single pulse without film is input from the film presence / absence detection circuit 466.

The count stop circuit 475 operates when the value of the subtraction counter 460 reaches a preset small value, for example, "7", and stops the counting operation of the subtraction counter 460. Therefore, even if there is room in the length of the film and there is a difference in the number of pictures that can be taken after that, the subtraction counter 46
0 cannot be "000".

Further, when the value of the subtraction counter 460 reaches a certain value, for example, "103", the film remaining amount detecting circuit 476 detects it, and the remaining amount signal generating circuit 477 generates the remaining amount signal by, for example, three pulses.

When the magazine status transmission circuit 471 inputs it, LED472
Flashes three times to notify the main unit 1 side.

The magazine state determination circuit 184 on the main body 1 side thereby determines that the remaining film amount in the magazine 4 is low, turns on the low film amount warning lamp 114, and turns on the buzzer 112 at a relatively short cycle (pip-pipipipip (...) Sounds for a predetermined time (for example, 2 seconds) and notifies it.

When the battery 461 is replaced, the initial reset circuit 478 operates to reset each part and the counter clear circuit 479 at the time of the battery set decrements the counter 460.
Is cleared and the display is changed to "000".

As described above, the film magazine 4 is provided with the subtraction counter 460, and the value is subtracted by the count pulse by the film winding from the main body 1 to obtain the detection signals of the film presence / absence detection circuit 466 and the film loading detection circuit 467. Since the count value is corrected accordingly, the accurate remaining film amount can be known.

Further, the presence / absence of a film in the magazine 4 and the condition of the remaining amount of the film can be transmitted to the main body 1 side to notify it by lighting a warning lamp or sounding a warning buzzer.

Finally, the pedestal 2 is provided with a motor control circuit 215 for controlling the drive of the motor 203 shown in FIG. 5 and micro switches 216, 217 for detecting the upper and lower limits of the driven screw 208.

Then, by operating the tilt buttons 606, 607 and 614, 615 of the first and second remote operation units 600, 610, the motor control circuit
215 controls the start-up and rotation direction of the motor 203, and moves the driven screw 208 up and down within a range regulated by the upper and lower limit micro switches 216 and 217 to change the inclination angle of the main body 1.

〔The invention's effect〕

As described above, in the photography apparatus with a self-monitor according to the present invention, when a film magazine containing a long film is mounted on the main body, the film magazine is locked by the locking means and mounted on the magazine. The mounting means is detected by the detection means, and the automatic idling means automatically feeds the long film in the film magazine by a predetermined number of frames by the detection means, so that light leakage from the aperture part of the long film is caused. The exposed portion is completely fed into the film magazine and the unexposed surface is fed to the aperture portion. Therefore, you can immediately start shooting without any preliminary operations.

In addition, even if the film magazine is taken out during the use of the long film, if the lock release is instructed by the lock release instruction means such as the hook release button, the automatic idling means first causes the long film in the film magazine to be released. Is automatically fed by a predetermined number of frames, and after the final photographing frame has been completely fed to a position where light leakage does not occur in the film magazine, the lock releasing means is operated to release the lock by the locking means.

As a result, it is possible to take out the film magazine for the first time, so it is completely impossible to take out the film magazine from the main body while the precious photographed screen of the long film is exposed in the aperture part, and it completely leaks. Can be prevented.
