DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-integrated camera with a strobe (= film unit with a lens) having a strobe integrated with a camera body, a charging function of a strobe circuit, and an indicator lamp for strobe light emission. The present invention relates to a structure of a film-integrated camera in which a lighting function of a light emitting diode used as a camera can be set without interfering with each other and an additional function is added to the light emitting diode.

[0002]

2. Description of the Related Art Some film-integrated cameras sold with a roll film that has not been exposed beforehand when the camera body is manufactured are equipped with a strobe provided integrally with the camera body. In this film-integrated camera with a strobe, the completion or charging of the strobe is notified by flashing of an indicator lamp by a neon tube. For example, in Japanese Patent Application Laid-Open No. 8-115796, an indicator lamp is used. Also, there is shown an example in which a light emitting diode having a high degree of freedom in setting is used at a low cost.

FIG. 6 shows a flash circuit diagram of a film-integrated camera using a light emitting diode as an indicator lamp. A flash circuit 1 includes a boosting circuit 2 for boosting a power supply voltage of a dry cell BT or the like, and a flash light emitting tube. It is roughly divided into a strobe light emitting circuit 3 for emitting Xe, and a boosting circuit 2 includes an oscillation transformer TR1 and an oscillation transistor Q, and a light emitting diode LED as an indicator lamp.
The strobe light emitting circuit 3 is provided with a strobe light emitting tube Xe, a main capacitor MC, a trigger switch TSW using an open / close switch, and the like.

The oscillation transformer TR1 of the booster circuit 2 has a primary winding W1 and a secondary winding W2, and a tertiary winding W3 serving as a feedback winding. Windings W1 and 2
A high voltage of AC is generated in accordance with a turn ratio of the secondary winding W2, and the tertiary winding W3 controls to stabilize the base potential of the oscillation transistor Q. Light emitting diode LE at both ends of W3
D to connect a light emitting diode lighting circuit (hereinafter, LED
4 (referred to as a lighting circuit).

The main switch MSW of the flash circuit 1
Is turned on by operating a strobe switch actuator provided on the outer surface of the camera body, and the main switch MSW is turned on.
The high voltage generated in the oscillating transformer TR1 by the turning on is charged to the main capacitor MC of the strobe light emitting circuit 3, the completion of charging of the main capacitor MC is notified by lighting of the light emitting diode LED, and the trigger switch TSW is turned on by the shutter switch. When turned on in conjunction with the blade, the flash tube Xe emits light and flash photography is performed.

[0006]

As described above, when a light emitting diode is used as an indicator lamp, it is possible to adjust the light emission amount and the lighting timing by utilizing the characteristics of the light emitting diode. In the above configuration in which the tertiary winding of the transformer is also used as the LED lighting circuit, the number of windings of the tertiary winding is set in accordance with the control of the oscillation transistor.
Increasing or decreasing the number of windings of the next winding causes a problem that charging characteristics change, such as a decrease in charging voltage and a long time for charging.

The light emitting diode is turned on only when the charging of the main capacitor MC is completed, and does not indicate that charging is in progress. For this reason, if the charging state in which the light emitting diode is not lit is mistaken for the strobe to be turned off and is stowed in a bag, pocket, or the like, the strobe charging operation continues and the power supply is wasted. Before using the film, there is a possibility that strobe photography cannot be performed.

Further, this kind of film-integrated camera is
Each time the shutter blades open, regardless of the strobe light emission, the operating piece integral with the shutter blades always hits the trigger switch of the strobe circuit, which accelerates the wear of the shutter blades and trigger switch, and also causes deformation and rust. Etc.
The number of reuses after collecting the camera body was reduced.

Further, as the size of the camera body is reduced in terms of cost and convenience in carrying, the photographing lens and the strobe come close to each other, so that the occurrence of the red-eye phenomenon easily occurs. As a countermeasure, adding a red-eye prevention function such as pre-flashing a strobe would go against cost reduction and miniaturization.

The present invention has been made in view of such a situation, and an object of the present invention is to make an LED lighting circuit electrically independent from a strobe circuit and to provide a lighting function of a light emitting diode with a strobe light. The flash function can be performed without interfering with the charging function of the camera, and the user can know when the flash is charging, improve the durability of the shutter blades and flash circuit, increase the reuse rate, and reduce the red-eye effect at low cost. It is an object of the present invention to provide a film-integrated camera that can efficiently prevent such a problem.

Accordingly, the primary winding W1 and the secondary winding W of the oscillation transformer TR1 are connected to the secondary winding W2.
An AC high voltage corresponding to the turn ratio of 2 is generated. The oscillation transformer TR1 is connected to a main capacitor (electrolytic capacitor) MC and a trigger capacitor TC of the strobe light emitting circuit 32 via a diode D.

To the opposite ends of the tertiary winding W3,
By using ones having different luminances and light emission characteristics, it is possible to change the light emission amount and lighting timing of the first and second light emitting diodes LED1 and LED2.

The ON state of the flash circuit can be easily known by the lighting of the light emitting diode, the user is notified that the flash is charging, and the power is turned on due to forgetting to turn off the flash switch. Since the useless use of the film is prevented beforehand, it is possible to prevent a problem that the flash photography cannot be performed before the use of the film is completed.

Further, according to the film-integrated camera of the second invention, the lighting function such as the light emission amount and the lighting timing of the light emitting diode is independently set without affecting the charging characteristics of the boost circuit of the strobe circuit.
