2. Description of the Related Art A film unit with a lens (trademark "Sharun Run Hi" manufactured by Fuji Photo Film Co., Ltd.) is widely used as a convenient photographing means for taking a picture when a user is not carrying a camera. This is one in which a film containing a cartridge is loaded in advance in a unit equipped with a photographing lens and a shutter, and can be purchased at a film store or the like. Then, after the shooting, the development of the whole film unit with lens and the printing are requested.

Conventionally, this lens-fitted film unit needs to be provided at a low price, and therefore, a photographing lens and a shutter are mounted on a unit formed of synthetic resin or the like as easily as possible, and a film is loaded, and the unit is mounted on a thick paper. It is housed in an outer box formed by. In addition, a film unit with a lens equipped with a strobe (Fuji Photo Film's trademark "Sharp Runn" is used to make the convenience more effective and to enable shooting even when sufficient brightness is not obtained. Flash ”) is being developed.

[0004]

In the lens-equipped film unit equipped with the strobe, the film is taken out from the unit at the developing station for development and printing. The unit or outer box after the film is removed is usually discarded because the user cannot practically reload the film, or is recovered by the manufacturer of the film unit. Since the strobe battery is in a state where it is not completely discharged when the stroboscopic light emission frequency is small, it can be reused depending on the application, and when the unit is discarded or collected, it is necessary to sort and collect the batteries. Therefore, at the photo lab, the battery must be removed from the unit along with the film.

However, the battery of the conventional lens-equipped film unit is disposed behind the reflector of the strobe, etc., and the film and the battery must be taken out separately at the developing station. When developing a large number of lens-equipped film units, it is troublesome and troublesome to take out the batteries. Therefore, an object of the present invention is to provide a lens-equipped film unit in which the battery for strobe light can be easily taken out by performing the work of taking out the film during development.

[0006]

In order to achieve the above object, the lens-fitted film unit according to the present invention comprises:
In a film unit with a lens, which is preloaded with a film, has a function of giving exposure to the film, and is equipped with a strobe so that it cannot be substantially reused after the taken film is taken out. An exposed film take-out opening is formed on the bottom of the film chamber in the unit, and one end of the exposed film take-out opening is continuous with the bottom of the film unit and is elongated in the lateral direction substantially along the underline of the front surface of the film unit. A strobe light emitting battery chamber opening is formed in a shape, and a film chamber lid is provided that shields the film chamber and opens for taking out the film.The film chamber lid covers the entire strobe light emitting battery chamber opening. It is characterized in that the covering lid is integrally formed.

[0007]

When the film is taken out for development, the film chamber lid is opened. As a result, the lid that has closed the battery chamber opening is also removed from the battery chamber opening, so that the battery is exposed and can be taken out. That is, the battery removal operation can be performed in addition to the film extraction operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The lens-fitted film unit according to the present invention will be specifically described below based on the illustrated embodiments. FIG. 2 is a perspective view of the lens-fitted film unit 1 viewed from the bottom surface 11. The unit 1 is made of synthetic resin or the like, and is divided into, for example, a front cover, a main body, and a rear cover, and molded.
After the film is loaded in the predetermined position of the main body, these are combined and completed. The rear cover is connected to the main body by ultrasonic bonding or a special locking structure so that the film is protected from light and the film cannot be reloaded after the taken film is taken out. On the front surface 12, a taking lens 1a, a finder 1b, and a stroboscopic light emitting window 1c are arranged so as to be exposed.

As shown in FIG. 1, the bottom surface 11 has a film chamber 2 which is a cartridge chamber for accommodating a film at a left end portion thereof, and accommodates a film-containing cartridge 3. In the vicinity of the film chamber 2 and below the taking lens 1a, a battery chamber 4 is formed so as to extend in a lateral direction along the lower edge of the front surface 12 of the unit 1, and a battery chamber opening 4a is formed in the bottom surface 11. Has been formed. A recess for mounting the lid of the film chamber 2 is formed on the bottom surface 11, and the recess and the battery chamber opening 4a partially communicate with each other. A strobe battery 5 is housed in the battery chamber 4. Further, the contact piece with which the battery 5 comes into contact is appropriately biased by a spring to prevent the battery 5 from easily coming off the contact piece. In addition, a concave portion 4b into which the tip of the driver or the like can be inserted is formed on the side surface of the battery chamber 4.

At the opening of the film chamber 2, a film chamber lid 6 as a patrone take-out lid for taking out the patrone 3 in which the photographed film has been wound is provided in the unit 1
One side is connected to the edge of the so that it can be opened and closed. When the film chamber cover 6 is opened, a tip of a driver or the like is inserted into the gap between the film chamber cover 6 and the unit 1 and opened as a boom. The film chamber lid 6 has a tip portion 6 which projects laterally to serve as a battery chamber lid.
