[Prior art]
An unexposed photographic film is loaded in advance, and a single-use lens-equipped film unit that can be photographed immediately on the spot is widely used. A film unit with a lens generally has a built-in strobe device that can shoot at night or indoors. In this strobe device, strobe circuit components are collectively mounted on a single substrate to form a unit, and are also commonly used on a substrate basis for different types of lens-equipped film units.
[0003]
By the way, the film unit with a lens has a photographing mechanism that is simple and downsized, and the exposure is fixed. For this reason, underexposure or overexposure may occur depending on the shooting situation. In order to eliminate such drawbacks, it has been studied to provide an exposure adjusting function in the lens-fitted photo film unit. In this case, it is desirable that exposure adjustment be performed by automatic control by photometry so that even a person unfamiliar with the camera can enjoy photographing easily. Therefore, it has been studied to incorporate a photometric circuit into the lens-fitted photo film unit so that the exposure can be adjusted automatically.

On the back of the strobe light metering window 7, a light metering element for detecting strobe reflected light is provided. A finder window 8 is formed above the photographing lens 6 to expose the finder lens. Further, there are provided a grip portion 9 on which a non-slip protrusion is formed and a strobe light emitting portion 10 that emits strobe light.
[0019]
The strobe charging knob 11 can be slid up and down, and strobe charging is started when the strobe charging knob 11 is slid upward. When the strobe charging is completed, the light emitting diode is lit inside, and this can be confirmed from the charging completion display window 12. If the flash charging is completed, when the shutter button is actuated by pressing the release button 3, the flash emission unit 10 emits light at the same time and flash photography can be performed.
[0020]
As will be described in detail later, the lens-fitted photo film unit 1 is provided with an auto strobe function for measuring the strobe reflected light incident on the strobe photometry window 7 during strobe photography. For example, during flash photography at a short distance, the flash emission amount is automatically controlled in order to prevent overexposure of the subject that occurs due to too strong strobe reflected light.
[0021]
As shown in FIG. 2, the lens-fitted photo film unit 1 has a form in which a main body base 16 provided with a photographing mechanism is covered from the front and back by a front cover 14 and a rear cover 15. The strobe unit 17 is unitized by mounting circuit components for a strobe on a substrate, and is incorporated between the front cover 14 and the main body base 16 via an attachment protrusion 18 provided on the main body base 16. The main body base 16 holds the photographing lens 6 in the center thereof. As is well known, the main body base 16 is provided with a shutter device for performing exposure by kicking the shutter blade 19 shown in FIG. A shutter charge mechanism that generates a kicking force for kicking off, and a film winding stop mechanism that locks the winding knob 20 at the same time that the film is wound up by one frame after the shutter operation is provided.

The main body base portion 16 is formed of a plastic molded product, and a cartridge chamber 21 in which a film cartridge 21 is accommodated and a film chamber 24 in which a film roll 23 in which a photographic film drawn in advance from the film cartridge 21 is rolled are accommodated. It is molded into. The winding knob 20 is engaged with a winding spool 25 provided on the film cartridge 21 on its axis.
[0023]
When a part of the winding knob 20 is exposed from the rear cover 15 and is rotated every time photographing is performed, the exposed film frame is moved toward the film cartridge 21. In addition, the shutter is charged in accordance with this rotation operation, and the next photographing preparation is performed.
[0024]
A top unit 27 is attached to the upper part of the main body base 16. The top plate unit 27 is configured by combining an opaque resin top plate on which the release button 3 is formed and a colorless and transparent resin top plate on which the counter window 4 is formed.
[0025]
Behind the shutter blade 19 is provided a dark box in which a photographing opening 30 is formed. At the rear of the dark box, an aperture that defines the exposure range of the subject light incident from the photographing aperture 30 is formed, and the film facing the aperture is exposed. The return spring 31 has one end engaged with the shutter blade 19 and the other end engaged with the main body base 16. The shutter blade 19 is biased to a closed position that covers the imaging opening 30 by the return spring 31. On the front side of the shutter blade 19, a lens holder 32, a diaphragm plate 33, a photographic lens 6, and a lens holder 34 are disposed.
[0026]
The strobe unit 17 is operated on the strobe main board 17a to which the battery contact piece 37 for holding the strobe light emitting unit 10 and the battery 36 is fixed, and the operation of the sync contact piece 38 which is turned on by opening the shutter blade 19 and the strobe charging knob 11. Various strobe circuit components such as a strobe power switch 39 that is turned on by the power supply and a main capacitor 40 that is charged with a high voltage are mounted.
[0027]
The strobe light emitting unit 10 is provided with a strobe discharge tube 41 (see FIG. 6) that emits strobe light by discharging the high-voltage charged main capacitor 40, and a reflector for efficiently irradiating the strobe light toward the subject. Yes.
[0028]
As shown in FIGS. 4 and 5, the strobe unit 17 is composed of two substrates, a strobe main substrate 17a and a strobe sub-substrate 17b. When the strobe sub board 17b is inserted into the pair of terminals 40a of the main capacitor 40, it is fixed by soldering. When the terminal 40a is attached to the strobe main board 17a, the strobe sub board 17b is fixed substantially vertically on the back side of the strobe main board 17a. A notch 42 is formed in the strobe sub-board 17b so as not to come into contact with circuit components mounted on the strobe main board 17a. In addition to the circuit components described above, the strobe main board 17a is provided with a light emitting diode 45 that is turned on when the strobe charging is completed, an oscillation transformer 46 that oscillates a high-voltage pulse, an oscillation transistor 47, and the like.
[0029]
As shown in FIG. 6, a strobe dimming circuit 49 on which a phototransistor 48 is mounted as a photometric element is provided on the strobe sub-substrate 17b. The strobe dimming circuit 49 is connected to the main strobe circuit 50 in parallel with the main capacitor 40 and the strobe discharge tube 41 by soldering the terminal 40a of the main capacitor 40 and the strobe sub-board 17b.
[0030]
The main strobe circuit 50 provided on the strobe main board 17a is supplied with power from the battery 36 by the blocking oscillation circuit composed of the oscillation transistor 46 and the oscillation transformer 47, and is supplied to the main capacitor 40 and the trigger capacitor 51. On the other hand, high voltage charging of about 300V is performed. Between the oscillation transformer 47 and both capacitors, a diode 52 for preventing a reverse flow of the charging current is provided.
[0031]
When the strobe charging knob 11 is slid upward, the strobe power switch 39 is turned on and the charging process is started. When the charging process is completed, the light emitting diode 45 is turned on, and this can be confirmed from the charging completion display window 11. The strobe power switch 39 operates the blocking oscillation circuit and prevents the trigger capacitor 51 from being discharged except when the switch is turned on.
[0032]
If the strobe power switch 39 remains on after the main capacitor 40 and the trigger capacitor 51 have been charged, strobe photography can be performed. When the shutter blade 19 is actuated by pressing the release button 3, the blade head 19 a is turned on by the rotation of the shutter blade 19 as shown in FIG. 7. When the synchro contact piece 38 is turned on, the trigger capacitor 51 is discharged, whereby a high trigger voltage is generated in the trigger transformer 53 and the strobe discharge tube 41 is excited. When the strobe discharge tube 41 is excited, the charge charged in the main capacitor 40 flows through the strobe discharge tube 41, and strobe light emission is performed. In this way, the main strobe circuit 50 on the strobe main board 17a functions as a strobe device that emits constant light independently.
[0033]
The strobe light control circuit 49 is provided with a power supply capacitor 55 serving as a power source for operating the light control function. The main strobe circuit 50 performs the charging process for the power supply capacitor 55 in parallel with the charging process for the main capacitor 40 and the trigger capacitor 51. When the power supply capacitor 55 is charged, the charging current flows through the Zener diode 56.
[0034]
When the strobe discharge tube 41 is excited and the main capacitor 40 is discharged, the charge charged in the power supply capacitor 55 flows through the strobe discharge tube 41, and the gate capacitor 57 is charged accordingly. The gate capacitor 57 is connected to the gate terminal of the SCR 58, which is a tripolar conduction thyristor. When the power supply capacitor 55 is discharged, a potential difference is generated between the emitter and the collector of the phototransistor 48. Therefore, when the strobe reflected light is detected by the phototransistor 48 at this time, a photocurrent flows according to the detected light amount, and this light Current is charged to the integrating capacitor 59.
[0035]
When the integrating capacitor 59 is charged to a predetermined voltage, the latch transistors 60 and 61 are turned on. As a result, the gate capacitor 57 is discharged, and the discharge current at this time flows through the resistor 62. At this time, a gate trigger voltage corresponding to a voltage drop in the resistor 62 is input to the SCR 58, whereby the SCR 58 becomes conductive.
[0036]
When the SCR 58 is turned on, the discharging main capacitor 40 changes the discharge path from the strobe discharge tube 41 to the SCR 58. At this moment, the strobe emission is stopped and the remaining charge in the main capacitor 40 flows through the SCR 58. The choke coil 64 slightly discharges the main capacitor 40 to prevent a large current from flowing through the SCR 58 abruptly. The auxiliary capacitor 65 is provided for preventing malfunction of the latch transistors 60 and 61 due to noise or the like.
[0037]
The strobe dimming circuit 49 is provided on the strobe sub-board 17b. The constant strobe main strobe circuit 50 provided on the strobe main board 17a functions as a strobe device having a bypass type automatic dimming function by connecting the strobe dimming circuit 49 to the main capacitor 40.
[0038]
By mounting the strobe circuit parts on the strobe main board 17a and the strobe sub board 17b, it is possible to easily make a strobe device for automatic light control and a strobe device for constant light emission. When a strobe main board 17a assembled with strobe circuit parts excluding the main capacitor 40 and a strobe sub-board 17b assembled with dimming circuit parts are prepared and a strobe device with constant light emission is manufactured, the main board is used. The main capacitor 40 may be attached to 17a. In the case of manufacturing an automatic light control strobe device, the main capacitor 40 may be connected to the strobe main substrate 17a after the strobe sub-substrate 17b is attached to the main capacitor 40.
[0039]
As described above, the strobe unit 17 can be changed from the automatic light control strobe device to the constant light emission strobe device simply by attaching / detaching the main capacitor 40. On the other hand, an automatic light control function can be added to a constant-emission strobe device. That is, in addition to versatility by sharing circuit components, compatibility can be provided between a strobe device with constant light emission and a strobe device having an automatic light control function.
[0040]
For the lens unit with lens, the applicant has collected the used product from which the film has been taken out of the cartridge, collected it, repaired it, and replaced it. It is active. Under such circumstances, unitizing the strobe device as described above can reduce the man-hours for repair and replacement of parts, and can immediately provide products with high demand to the market.
[0041]
The strobe device of the present invention can be incorporated not only in a lens-equipped film unit as in the above embodiment, but also in a general camera that can be replaced at a low cost, such as a compact camera. Is possible. In this case, on the camera side, an operation means for performing a flash charging process is provided on the outer surface of the camera so that the flash power switch can be easily turned on and off. Further, the trigger circuit is operated so that strobe light emission is performed simultaneously with the operation of the shutter.
[0042]
