Abstract

PURPOSE: To simultaneously obtain plural photographed negative films for a commemorative photograph by adopting such a constitution that the shutter of a camera is automatically actuated by the actuation of the shutter of the other camera. CONSTITUTION: A large-sized camera for business A and a small-sized camera B are used and constituted so that their shutter mechanisms and stroboscopes are electrically connected and the shutter of either of the cameras, for instance, the camera B is set in an opened state to actuate the stroboscopes while the shutters of each camera is opened. Then, all the shutters are in a motor-driven type, an electric signal for making the shutter of the camera B the opened state is instantaneously transmitted to the motor-driven shutter mechanism of the other camera A and it is almost simultaneously actuated with the shutter of the camera B with the transmitted electric signal, so that all the shutters are set in the opened state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera and a photographing method, and more particularly to a camera and a photographing method capable of simultaneously obtaining a plurality of photographing negative films in commemorative photographing.

[0002]

2. Description of the Related Art Conventionally, commemorative photographs have been taken in almost all cases at Shichigosan, entrance ceremony, graduation ceremony, weddings and the like. In the case of formal commemorative photography, aside from the snapshots, a high-quality photography is performed by a professional photographer in the photography studio.
In the case of these official memorial photographs, the same camera or the same camera is usually used for the same subject in preparation for the blinking of the person as the subject, other unintended camera failures, poor shooting, poor development at the photo lab, etc. Is 3 ~ with multiple cameras
I took four shots and selected the best negative film to take a formal photo. The present invention will be described based on the case where an ordinary silver salt photographic film is used as a photographic recording medium. The "film" in the present specification means a recording medium other than a magnetic recording medium, an optical recording medium, or the like. Shall also be included.

[0003]

[Problems to be Solved by the Invention] In the case of the above-mentioned conventional commemorative photo taking method, since the commercial camera is large and expensive, it is costly and space-consuming to use three to four cameras. It is uneconomical, and even if one camera is used to take a plurality of times, there are problems in that taking 3 to 4 times is time consuming and complicated. In particular, when an infant or a child is mixed in the subject, the child or the infant gets tired between a plurality of times of photography, which makes it difficult to take a good picture. Furthermore, when making postcards using these souvenir photographs as manuscripts, since there is only one formal photo film, the negative film may be sent to the printing place after making the souvenir photo, or Duplicates are required, and these are also time-consuming and complicated. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a camera and a photography method capable of obtaining a plurality of film negative films at the same time in commemorative photography.

[0004]

Problems to be Solved by the Invention The above object is achieved by the present invention described below. That is, the present invention comprises one large-sized commercial camera, one or more small cameras, and a strobe, and the shutter mechanism of the plurality of cameras and the strobe are electrically connected to each other, and the shutter of any one of the cameras is used. The shutters of all the remaining cameras are automatically activated by activating the, and the strobe is activated within the time when all the shutters are in the open state, and a camera using the same. It is a method of taking pictures.

[0005]

[Operation] By electrically connecting one commercial large-sized camera, one or more small-sized cameras, and a strobe so that their shutter mechanisms work together, and by operating the shutter of any one of the cameras , By automatically activating the shutters of the remaining cameras so that all the shutters will be activated within the open time,
Since a plurality of film negative films can be obtained at the same time by one shot, the above-mentioned various problems caused by using a plurality of cameras separately and taking a plurality of photographs by one camera are all solved. Will be resolved to.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described more specifically with reference to one embodiment shown in the drawings. 1 and 2, the camera and the photographing method of the present invention are composed of one large commercial camera A and one or more small cameras B, as shown in FIG. 1 and FIG. The shutter mechanism of each of the cameras A and B and the strobe are electrically connected to each other. By opening the shutter of any one of the cameras, for example, the shutter of the camera B, its signal causes the shutter of the camera A to be opened. The strobe is activated while the shutter of each camera is opened.

All shutters are electrically operated,
An electric signal for opening the shutter of the camera B is instantaneously transmitted to the electric shutter mechanism of the other camera A, and the transmitted electric signal causes the shutter of the other camera A to operate almost simultaneously with the shutter of the camera B. Then, all the shutters are open. There is a very short time lag between the operation of the shutter of camera B and the operation of the shutter of other camera A, but the time during which each shutter is open is usually about 1/60 second, while the flash exposure time is Since it is usually about 1/300 second, the flash exposure can sufficiently expose the film built in all the cameras while all the shutters are open.

Next, an example in which a commercially available camera is partially modified and combined to form the camera of the present invention will be described. Mamiya R2II manufactured by Mamiya OP Co., Ltd. is used as a large commercial camera, and Ricoh XR manufactured by Ricoh Co., Ltd. is used as a small camera.
10M was used. As shown in FIG. 1 and FIG. 2, these cameras were arranged so that the signal from the X-contact from the hot shoe of camera B was connected to the remote connector of camera A to obtain synchronization. The remote connector for camera A was connected as shown in Fig. 2 for the synchro cord hot shoe. The operation of the combined camera and strobe is as shown in FIG. When the shutter of the camera B is opened, the synchro contact is energized, and this current is used as the operation signal of the camera A, the shutter opening signal of the camera A is transmitted to the strobe, and the strobe operates. In the above operation, since a slight time lag occurs in the operation of the camera B, the camera A and the strobe,
As shown in FIG. 3, it is necessary to electrically connect the cameras B and A to each other so that the strobes operate within the shutter open time.

[0009]

[Effects] According to the present invention as described above, one large commercial camera, one or more small cameras, and a strobe are electrically connected so that their shutter mechanisms work together, and any one of them is connected. By operating the shutters of the other cameras, the shutters of the remaining cameras are automatically activated, and multiple shooting negative films can be obtained at the same time in one shooting. The above-mentioned various problems caused by taking a plurality of times of photographs with this camera are solved at once.
