Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of switching between panorama size and full size shooting.

[0002]

2. Description of the Related Art Conventionally, when a single camera capable of switching between full-size and panoramic-size shooting is used to shoot full-size and panoramic-size images, it is sufficient for the lab to display both pictures on a single film. Therefore, one full-size film and one panorama-size film are used.

[0003]

However, the above-mentioned conventional example has the following drawbacks when it is desired to continuously shoot panorama size and full size with one camera. (1) If you want to continue panoramic shooting during full-size shooting, you must either rewind by force or shoot the film currently in the camera until you can switch to panoramic shooting and perform panoramic shooting. (2) On the other hand, even if you want to perform full-size shooting during panorama shooting, you cannot perform full-size shooting unless you forcedly rewind or shoot the current film. As described above, the remaining film is wasted when switching to panorama shooting during full size shooting or when switching from panorama size shooting to full size shooting.

An object of the present invention is to provide a panoramic camera which eliminates the above-mentioned drawbacks of the prior art and does not waste the film even when switching between panoramic size shooting and full size shooting.

[0005]

In order to achieve the above-mentioned object, the present invention relates to a camera capable of switching between panoramic size shooting and full size shooting, and a place for storing the film state and the camera state, and corresponding thereto. A plurality of control switches are provided.

[0006]

In the camera having the above structure, by turning on the first control switch at the time of panoramic photography, in the rewind mode, the current film state and camera state are stored in the first storage location, and the reader unit is stored. Rewind in the state that was put out. Then, by switching to the full-size / panorama size changeover switch to the full-size shooting and inserting another film, the full-size shooting can be performed as usual. Also,
By turning on the second control switch in the middle of full-size shooting, the state of the camera and the state of the film are stored in a second storage location different from the previous one, and the image is rewound with the reader unit extended. At this time, the full-size / panorama size changeover switch is used again to switch to panoramic photography, the film is inserted, and the state of the film stored in the first storage location and the state of the camera are read before turning on the first control switch, and the same. After confirming whether or not the film is a film, the film is fed to the counter value of the film which was previously photographed, and is returned to a state in which panoramic photographing can be performed before the first first control switch is pressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of this embodiment. In the figure, reference numerals 1, 2 and 3 are first, second and third control switches for controlling the camera, respectively, and 4 is a switch detecting means for detecting and determining the first to third control switches 1 to 3. is there. Reference numeral 5 is a control means for performing control by a signal from the switch detection means 4, and 6 is a first data storage area (RA for storing the state of the film and the state of the camera.
M) and 7 are also second data storage locations (RAM), 8 is also third data storage location (RAM), 9 is a rewind switch, 10 is motor drive means for driving the motor 11, and 11 is a film. A motor for feeding and rewinding,
12 is an ISO state of the film, a film detecting means for detecting how many pictures have been taken and the number of film counters at present, 13 is a panorama-full size changeover switch, 14 is a camera state for detecting whether the camera is in a panorama shooting state or a full size shooting state It is a detection means.

The operation of this embodiment having the above configuration will be described with reference to the flowchart of FIG. First, when the first control switch 1 is turned on in # 1, the state is detected by the switch detection means 4
Then, in step # 2, it is determined which control switch is pressed, and the data is sent to the control means 5. If the rewind switch 9 is turned on in # 3, the control means 5 determines that the rewind operation is performed,
Film state detecting means 12 and camera state detecting means 14
Send a signal to. The film state detecting means 12 receiving the signal at # 4 reads the ISO sensitivity of the film and the number of shots of the film, and further at # 5 sends the data to the control means 5 together with the current number of film counters. .. Also, # 6
At the same time, the camera state detection means 14 which has received the signal reads the state of the panorama-full size changeover switch 13 and sends data to the control means. In # 5, the control means 5 sets 0 according to the film counter data from the film state detection means 12.
In this case, the data is not stored in the storage location, and a signal is sent to the motor drive means 10 in # 8 to drive the motor 11 and rewind with the reader unit exposed. On the other hand, if the film counter data is not 0 in # 5, the first to third data storage locations 6 to 8 are selected according to the data from the switch detecting means 4 in # 7, and the film state detecting means 12 and the camera state are selected. The data sent from the detection means 14 is stored in the data storage location selected earlier, and the motor drive means 1 is stored in # 8.
A signal is sent to 0, the motor 11 is driven, and the leader part is unwound and rewound.

Further, if any of the first to third control switches 1 to 3 is pressed and the rewind switch 9 is turned off in # 3, the control means 5 judges that the sheet is fed, and switches in # 9. The first to third data storage locations 6 to 8 are selected based on the data from the detection means 4, and the selected first to third storage locations 6 to 8 are selected.
Read data from 8. However, if the data of the storage location is 0 in # 10, nothing is done. If it is not 0, a signal is sent to the film state detecting means 12 in # 11, and the film state detecting means 12 which has received the signal is presently turned on. The control means 5 controls the ISO state of the film and the number of shots taken.
Then, the control means 5 compares the data with the data from the storage locations 6 to 8, and if they are not equal in # 12, nothing is done,
If they are equal, the data is sent to the camera state detecting means 14. The camera state detecting means 14 that has received the signal in # 13 displays the current panorama-
The data of the state of the full size changeover switch 13 is sent to the control means 5, and the control means 5 compares the data with the data of the storage locations 6-8. If # 14 is not equal, do nothing,
If it is equal, the first to third data storage locations 6 to 8 in # 15
The data of the film counter read from is sent to the motor driving means 10, the film is fed by the motor 11, and the film counter is wound up to the sent film counter value.

Although the film counter is wound up to the film counter value in the above-described embodiment, when the film counter value is fed, an error may occur depending on how the film is loaded even if the number of counters is the same. It is also possible to feed a certain number of extra pulses. Further, when the current film status and camera status are different from the data in the data storage location (RAM), the display may be performed.

[0011]

As described above, according to the present invention, by having a plurality of storage locations for storing the film status and the camera status and a plurality of control switches corresponding thereto, even if one camera is in the middle of shooting, This has the effect of reliably switching between panorama size and full size shooting without wasting the film.
