DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a block diagram showing a basic form of a strobe power supply circuit used in a continuous photographing apparatus such as a vehicle according to the present invention. The strobe power supply circuit basically includes a high voltage circuit and a charge / discharge control circuit 14. The high voltage circuit includes a converter and an output circuit. The output voltage (P _out ) of the output circuit is supplied to the strobe head as a light emission output. B
Are connected to the charging / discharging circuit 14 via the. The charge / discharge control circuit 14 generates a charge or discharge signal based on the information.

Next, an embodiment of a first continuous photographing apparatus for a vehicle or the like according to the present invention will be described with reference to FIGS. 1 and 2A and FIG. An output for light emission is supplied to the charge / discharge control circuit 14 (
P _out ) is fed back. When the voltage of the light emission output falls below a predetermined voltage, converters 2a, 2b to 2n
Is activated, the voltage of the NiCd batteries 1a, 1b to 1n is boosted, and the capacitor in the output circuit 3 is charged to a predetermined voltage. The example of FIG. 2A shows three converters 2
a, 2b, and 2c, respectively, and capacitors 4a, 4c
This is an example in which b and 4c are provided. Each capacitor 4a, 4b,
The anodes of the SCRs 5a, 5b, 5c are connected to the output of 4c, and the cathodes are commonly connected. Each SCR5a, 5
Gate circuits 6a, 6b, 6c are connected to the gate terminals of b, 5c.
Is connected. The gate circuit is a circuit in which a resistor and a capacitor are connected in parallel, and is a circuit for starting the SCR. Each of the SCRs 5a, 5b, 5c is activated at each time of photographing, and the capacitors 4a, 4b, 4c are discharged, and the capacitors are sequentially charged from the discharged capacitors. When it returns to the capacitor, the battery is already charged to the predetermined voltage, and continuous photographing for an extremely short time becomes possible.

FIG. 2B shows an example in which three converters 2
diodes 7a, 7 respectively corresponding to a, 2b, 2c
The anodes b and 7c are connected. The cathodes of the diodes 7a, 7b, 7c are commonly connected, and the capacitor 8 is connected. When the charging voltage of the capacitor 8 falls below a predetermined value, the charging is performed simultaneously by the three converters 7a, 7b, 7c, so that the charging can be performed at high speed. FIG. 3 is a diagram illustrating a circuit that controls light emission synchronization of the camera. FIG.
When the charging voltage of the capacitors 4a, 4b, 4c of FIG. 2A and the capacitor 8 of FIG. 2B reaches a predetermined voltage, the light emitting diode 9 emits light to indicate the completion of charging. The charge completion signal is
The light emitting diode 10a of the photocoupler 10 also emits light, and the phototransistor 10b conducts. As a result, a signal for permitting photographing is transmitted to the remote control terminal 12. With this circuit, after a certain amount of charge is reached,
That is, the strobe and the camera can emit light completely synchronously.

FIG. 4 is a circuit diagram showing an embodiment corresponding to a first continuous photographing apparatus for a vehicle or the like according to the present invention. The strobe power supply 15 further includes a capacitor n in the output circuit shown in FIG. The number of converters is also increased correspondingly. A camera 28, a strobe power supply 15,
It is configured by connecting to a strobe head 27. The camera 28 has a dark red filter 31 disposed in front of a shutter 30. The dark red filter 31 is a filter that passes only light having a longer wavelength than dark red,
Is a film sensitive to light having a longer wavelength than dark red. The X-contact output of the camera, which is generated when the camera 28 is released, is connected to the strobe power supply 15 via a cable.
Is input to the synchronizing circuit 23 of the charge / discharge control circuit.

The high-voltage circuit of the strobe power supply 15 has n converter circuits 17a, 17b to 17n to which NiCd batteries 16a, 16b to 16n are connected, respectively. Output capacitors 18a, 18b to 18n are connected to outputs of the n converter circuits 17a, 17b to 17n, and anodes of SCRs 19a, 19b to 19n are connected to outputs of the capacitors 18a, 18b to 18n. The cathodes of the SCRs 19a and 19b to 19n are connected to one end of a xenon tube 26 of a strobe head 27. The synchronizing circuit 23 includes a differentiating circuit including a capacitor and a resistor, and generates a pulse wave from a synchronizing contact (X contact) signal.

The pulse wave of the synchronizing circuit 23 is distributed by a ring counter circuit 24, and the distributed pulse wave is S
Gate circuits 20a, 20 of CRs 19a, 19b to 19n
b to 20n. Accordingly, a pulse wave generated by the synchro X contact signal input for each photographing operation enters the gate circuits 20a, 20b to 20n in order, and the SCR 19
a, 19b to 19n are turned on. The pulse wave of the synchronization circuit 23 is further input to the trigger circuit 22. On the other hand, the outputs of the output capacitors 18a, 18b to 18n are input to the trigger circuit 22 via the diodes 21a, 21b to 21n. Trigger circuit 2
2 outputs a trigger signal to the trigger coil 25 in response to the above-described pulse wave when any of the outputs of the output capacitors 18a and 18b to 18n has a voltage equal to or higher than a predetermined voltage.

At this time, upon receiving the synchro contact signal, one of the SCRs 19 is turned on, and the output capacitors 18a, 18b to 18n connected to the SCR 19 are turned on.
, The xenon tube 26 is triggered to emit light. A dark red filter is provided on the front surface of the xenon tube 26, and emits only light having a longer wavelength than dark red from the strobe head 27. A vehicle or the like is irradiated with the stroboscope (a portion composed of the strobe power supply 15 and the strobe head 27), and the reflected light returns to the camera 28. Since the mirror 28 of the camera 28 is raised by the release operation and the shutter 30 is opened, only the reflected light having a wavelength longer than that of the dark red that has passed through the dark red filter 31 reaches the film 29 and photography is performed. In continuous shooting (continuous mode), the next shutter is released at time intervals determined by the performance of the camera. In this case, even with a high-performance camera (for example, 5 frames / second) in which the continuous shooting time is extremely short, at least the number of frames equal to the number of condensers 18 must be strobed with a predetermined voltage to continuously shoot. Can be.

Since the capacitors 18a, 18b, etc., which have been initially discharged have been charged again when all the capacitors have been discharged, it is possible to continuously shoot more than the number of capacitors. How much continuous shooting is possible with reliable strobe light emission depends on the number of capacitors, charging speed capability and continuous shooting speed of the camera. For example, if the continuous shooting speed of the camera is 5
Even in the case of frames / second, if the number of capacitors and the charging speed are increased, the number of continuous shootings can be increased. In theory, the time from discharge to charging of one capacitor is shorter than the interval between continuous shootings. Even if it is applied, it is possible to continuously shoot about the number of frames of the film.

Next, in the case of continuous shooting in the one-shot mode instead of continuous shooting, the shooting interval is considerably longer than the continuous shooting even if the shooting is performed as fast as possible. Therefore, if continuous shooting of a predetermined number of frames can be performed, there is no problem in continuous shooting in the one-shot mode.

Next, FIGS. 1 and 2B, 3 and 6
An embodiment of the second continuous photographing apparatus such as a vehicle according to the present invention will be described with reference to FIG. FIG. 2B shows an example in which diodes 7a, 3a corresponding to three converters 2a, 2b, 2c, respectively.
The anodes 7b and 7c are connected. The cathodes of the diodes 7a, 7b, 7c are commonly connected, and the capacitor 8 is connected. When the charging voltage of the capacitor 8 falls below a predetermined value, the three converters 7a, 7b and 7c charge the capacitor 8 at the same time, so that the capacitor 8 is charged at a high speed.

FIG. 3 is a diagram showing a timing control circuit 38 for controlling light emission synchronization of the camera in response to charging completion. FIG. 6 is a circuit diagram showing an embodiment of the second continuous photographing apparatus such as a vehicle shown in FIG. The capacitor 8 of FIG.
2 (or the capacitors 4a, 4 in FIG. 2 (a)).
The same applies to each of b and 4c. ) Becomes a predetermined voltage, and when a charge completion signal is generated, the light emitting diode 9 emits light to indicate that the charge is completed. The light-emitting diode 10a of the photocoupler 10 of the timing control circuit 38 is caused to emit light by the charge completion signal, whereby the phototransistor 10b is turned on. When a switch 11 (for example, a switch indicating completion of winding or a switch for designating a continuous operation mode) is turned on, a signal for permitting photographing is connected to the remote control terminal 12, and an X contact signal is output when the camera is operated. Is the charge / discharge control circuit 1
4 (FIG. 1 or FIG. 6). As a result, it is possible to make the strobe and the camera emit light completely after the predetermined amount of charge is reliably reached, that is, the strobe and the camera. FIG.
When the output circuit shown in (b) is employed, the number of capacitors is one, and the converter is charged from a large number of converters. Therefore, compared to the output circuit of FIG. Since the number of converters is increased by the number of converters, even if the number of capacitors is small, continuous shooting of the same number of frames can be sequentially performed on condition that charging is completed.

FIG. 5 is an external perspective view showing another embodiment of a continuous photographing apparatus such as a vehicle according to the present invention, and shows a state where the apparatus is actually arranged on a road. In this embodiment, for example, the photographing speed of the camera is 2 frames / sec, the shutter speed is 1/250 sec, and a photographing distance of 7 to 15 m is assumed. The difference from the embodiment shown in FIG. 4 is that vehicle detectors 33 and reflectors 34 are provided at both ends of the road to obtain detection points, so that automatic photographing can be performed. The vehicle detector 33 irradiates the reflector 34 with light longer in wavelength than dark red. When the vehicle 46 enters the detection point, the reflected light from the reflector 34 is blocked, and the vehicle detector 33 outputs the detection timing signal to the timing control unit 38 of the charge / discharge control circuit of the strobe power supply 37 (see FIGS. 3 and 6). To send to. This allows
Each time the vehicle enters the detection point, the camera 35 performs the first flash photography from the front when the vehicle reaches the photographing area. After that, shooting is performed at the shortest interval in synchronization with the completion of charging of the capacitor.

FIG. 6 is a circuit diagram showing an embodiment of the circuit of the continuous photographing apparatus such as a vehicle shown in FIG. The detection timing signal from the vehicle detector 33 is input to the timing control unit 38. The timing control unit 38 makes a timing time at the shooting position with respect to the detection point, and sends a shutter signal to the camera 35.

(B) is the figure seen from the front. The strobe power supply 37 and the strobe head 36 are connected by connecting a male connector 45 provided at one end of the cable 43 to a female connector 46 provided on the upper surface of the strobe power supply 37.
A connection terminal 47 for connecting to a hot shoe of the camera is provided next to the female connector 46. A power switch and a display unit 44 are further provided on the upper surface of the strobe power supply 37. The display unit 44 displays a battery remaining amount display and a charge completion display. In this embodiment, if a strobe power supply with a built-in high-speed module and a battery unit are used, the strobe can emit light so that continuous shooting at 3 frames / sec is possible.

The winder 42 is attached to the lower cover 5. This makes it possible to automatically wind a camera that does not have an automatic winding device. When the winder is mounted on a camera having a built-in automatic winding device and capable of mounting the winder, the winding mechanism is switched to the winder side, so that faster winding is possible.

In each embodiment of the present invention, a strobe power supply,
The strobe head, the camera, the vehicle detector, and the reflector are small and portable so that they can be easily installed in any place and are convenient to carry. The strobe power can be carried around the shoulder with a shoulder belt. When the entering vehicle is detected by the vehicle detector shown in FIG. 5, the timing control unit 38 sends a shutter signal at a timing when the vehicle enters the photographing position. You can take the way. For example, shooting may be performed by detecting the leading vehicle of a runaway tribe group that runs, unconditional continuous shooting of the following vehicle, or shooting may be performed each time a second or subsequent succeeding vehicle is detected. It is possible. In order to identify the frame of the film after development, the serial number can be imprinted on the photographic film by setting the content of the imprinted film on the camera data back to the serial number.

And emits light having a wavelength longer than that of dark red, and can be continuously synchronized with strobe light to enable continuous photographing. Therefore, it is possible to supplement a runaway group or the like that does not know when and where it appears, and to reliably record a photo of the group within a time of more than ten seconds passing the detection point, and collectively photograph a large number of vehicles and the like. It is extremely effective in cases.
