Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a film-integrated camera in which a film is built-in and a photo-taking lens is taken out to take out the photo-taken film after shooting is finished by a taking lens.

[Background and purpose of the invention]

The film-integrated camera is also called a disposable camera,
The camera is loaded with film from the beginning, and when shooting is finished, the film is returned to the developing place, where the camera skein film is taken out and developed. Since the mission of a camera ends when the filming of one film is finished, it is required that the camera be as inexpensive as possible and easy to take, and that the taken picture is definitely taken. For this reason, a film-integrated camera with a built-in high-sensitivity film, fixed focus, fixed aperture, and first-speed shutter is the basic form because it is easy to operate and the structure is simple and inexpensive. .

However, the above-mentioned film-integrated camera cannot obtain a satisfactory photographing result for a wide range of subjects such as bright and dark conditions. A film-integrated camera equipped with a strobe alleviates this problem.

If the number of shooting opportunities increases and a large number of photos are taken at recreational places, etc., it will be confusing in organizing the printed photos because the date taken was not known.

A compact camera equipped with a date unit that selectively records the date of shooting and the date and time has already been developed. It has a built-in strobe, or has a battery power source to drive the motor drive camera. However, in a small camera equipped with a date unit, a date unit with a different power source is attached to the back cover of the camera without using the above battery power source, and the date information to be separately copied can be observed from the outside. There is also a monitor, and the person who shoots the camera checks the data imprinted on the monitor,
Sometimes I used to select data and then imprint a date. At this time, it is inevitable that the camera cost will be considerably increased by mounting the date unit having the above-mentioned function on the camera. In most cases, the strobe battery built into the film-integrated camera still has sufficient energy even if stroboscopic photography is performed for all frames of the built-in film. However, the battery is normally discarded after the film is taken out from the film-integrated camera, and the energy remaining in the battery is wasted.

The present invention is a film-integrated camera equipped with a strobe capable of imprinting a date, in which the cost is kept to a minimum and the energy of the strobe battery is effectively used. It is an object to provide an integrated camera.

[Constitution of device]

The above-mentioned purpose includes a strobe and a power source for the strobe,
In a film-integrated camera with a strobe, in which an unexposed film is loaded in advance in the camera body, a date control unit incorporating a crystal oscillator and a clock circuit, and date information output from the date control unit are copied onto the film. A date imprinting section to be embedded is provided in the camera body, and the power source of the strobe is a drive power source for the date control section and the date imprinting section.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a front view of the film-integrated camera, and FIG. 2 is a sectional view of a main part.

The film-integrated camera 1 of the present invention is a camera that uses a taking lens 11 having an F number of F11, which is a single lens.
Behind 1 is a fixed diaphragm 12 and a single-blade shutter 13, and by pressing a release button 19 provided on the upper surface of the camera, the film F is exposed at a first shutter speed. Further, the camera body 1 has a film supply chamber 14 and a film winding chamber 15 on the left and right, and the film F wound in the film supply chamber 14 is addressed to one by the exposure unit 16 having a screen frame. The film F is exposed, and the film F is wound into the cartridge P in the film winding chamber 15 by winding up the curtain knob 17.

A fan-inder 18 is provided at the upper edge of the camera body 1 and a strobe light-emitting portion 21 is provided at the upper corner. The strobe light emitting portion 21 is provided with a strobe light emitting tube 21a on the front surface of the reflector, and the strobe unit boosts the voltage of the power source 20 composed of the AA or AAA battery by the strobe boosting circuit 22 to synchronize with the shutter. Turn on the trigger switch SW (T)
By doing so, the strobe light emitting tube 21a emits light.

In addition, there is a date imprinting section 25 using a liquid crystal or the like on the back surface of the film of the exposure section 16, and from the back surface of the film F,
Month / day or month / day date information is imprinted. The date imprinting section 25 is also driven by the same power source 20 as the strobe power source, and the date imprinting section 25 imprints it on the film screen by the date information output from the date control section 26 having a built-in crystal oscillator and clock circuit. . The camera body 1 is provided with a switch SW (D) for switching between "imprint date" and "no date". When "imprint date" is selected for the switch SW (D), the corner of the shooting screen is displayed. When the shooting date is imprinted on the page and "No date" is selected, date information is not imprinted.

The date unit used in the present embodiment is the simplest and cheapest date unit, the monitor portion of the date information to be imprinted is abolished, and the date to be imprinted is also month / day or year / month / day. It is limited to any one of.

In the embodiment, the film-integrated camera equipped with a strobe using a xenon lamp incorporated in a general small-sized camera has been described, but the present invention is not limited to this. For example, a tungsten lamp or the like is used to reduce the light amount. , It is also applied to a camera equipped with a low-priced flash lamp, and in this case, the power source of the light emitting lamp is also configured to be shared with the date unit.

Further, the stroboscopic light emission may be such that it always emits light at the time of photographing as shown in the embodiment, or a changeover switch may be provided to selectively emit light only when the subject is dark.

[Effect of device]

The film-integrated camera according to the present invention has a built-in date unit with the simplest structure that is the most basic, and shares its power source with the power source for strobe. Since a dedicated power supply is not required, the number of parts and the space used are not required so much, and thus it is possible to provide a film-integrated camera capable of recording a date without making the camera too large.

In addition, the surplus energy of the strobe battery, which has been conventionally discarded after the film is taken out, can be effectively used for driving the date control unit and the date imprinting unit, and the energy wasted can be reduced.
