Abstract

A camera includes a motorized film winding mechanism, a motorized film rewinding mechanism, a winding control circuit with two selectable modes, in one of which every frame of the film is exposed and in the other the film is wound with a frame left unexposed, a memory for memorizing the position of the unexposed frame when the second winding mode is selected, a rewinding control circuit with two selectable modes, in one of which the film is continuously rewound and in the other the film is stopped with the unexposed frame in registry with the exposure aperture, a first selecting circuit for selecting the second winding mode and a second selecting circuit for causing the rewinding control circuit to operate in the second rewinding mode when the second winding mode has been selected.

Claims

1. A camera comprising:

film winding means for performing electrically-driven winding of a film;

film rewinding means for performing electrically-driven rewinding of the film;

first control means for causing said film winding means to wind the film whereby at least one film frame is left unexposed, and for causing said film rewinding means to rewind the film whereby the film is stopped at the position of the at least one unexposed frame, to expose the at least one unexposed frame at the time of the rewinding;

mode setting means for setting a specific photographing mode; and

second control means, responsive to setting of the specific photographing mode by said mode setting means, for causing said film winding means to wind the film for exposing every frame.

2. A camera according to claim 1, wherein said first control means causes said film winding means to wind the film by two frames and said film rewinding means to rewind the film by two frames.

3. A camera according to claim 1, further comprising display means, responsive to setting of the specific photographing mode by said mode setting means, for displaying the setting of the specific photographing mode.

4. A camera according to claim 1, wherein the specific photographing mode is a continuous shooting photographic mode.

5. A camera according to claim 3, wherein the specific photographing mode is a continuous shooting photographic mode.

6. A camera comprising:

film winding means for performing electrically-driven winding of a film;

film rewinding means for performing electrically-driven rewinding of the film;

first winding control means for causing said film winding means to wind the film for exposing every frame;

second winding control means for causing said film winding means to wind the film whereby at least one film frame is left unexposed;

memory means for memorizing the position of the at least one unexposed frame when the winding is caused by said second winding control means;

first rewinding control means for causing said film rewinding means to continuously rewind the film;

second rewinding control means for causing said film rewinding means to rewind the film whereby the film is stopped at the position of the at least one unexposed frame based on information obtained from said memory means;

mode setting means for setting a specific photographing mode;

first selecting means, responsive to setting the specific photographing mode by said mode setting means, for forcibly selecting said first winding control means; and

second selecting means, responsive to the selection of said first winding control means by said first selecting means, for forcibly selecting said first rewinding control means.

7. A camera according to claim 6, wherein said second winding control means causes said film winding means to wind the film by two frames.

8. A camera according to claim 6, further comprising display means, responsive to setting the specific photographing mode by said mode setting means, for displaying the setting of the specific photographing mode.

9. A camera according to claim 6, wherein the specific photographing mode is a continuous shooting photographic mode.

10. A camera according to claim 8, wherein the specific photographing mode is a continuous shooting photographic mode.

11. A camera comprising:

film winding means for performing electrically-driven winding of a film;

film rewinding means for performing electrically-driven rewinding of the film;

winding control means for selecting either a first winding control mode which causes said film winding means to wind the film for exposing every frame, or a second winding control mode which causes said film winding means to wind the film whereby at least one film frame is left unexposed;

memory means for memorizing the position of the at least one unexposed frame when the second winding control mode is selected;

rewinding control means for selecting either a first rewinding control mode which causes said film rewinding means to continuously rewind the film, or a second rewinding control mode which causes said film rewinding means to rewind the film whereby the film is stopped at the position of the at least on unexposed frame based on information obtained from said memory means;

first selecting means for selecting the second winding control mode; and

second selecting means for selecting the second rewinding control mode when the second winding control mode has been selected by said first selecting means.

12. A camera according to claim 11, wherein the second winding control mode causes said film winding means to wind the film by two frames.

13. A camera according to claim 11, further comprising display means for displaying operations of the first winding control mode and the second winding control mode.

14. A camera comprising:

film winding means for performing electrically-driven winding of a film;

film rewinding means for performing electrically-driven rewinding of the film;

winding control means for selecting either a first winding control mode which causes said film winding means to wind the film for exposing every frame, or a second winding control mode which causes said film winding means to wind the film whereby at least one film frame is left unexposed;

first memory means for memorizing the position of the at least one unexposed frame when the second winding control mode is selected;

second memory means for memorizing either a winding state of the film or a rewinding state of the film;

rewinding control means for selecting either a first rewinding control mode which causes said film rewinding means to continuously rewind the film, or a second rewinding control mode which causes said rewinding means to rewind the film whereby the film is stopped at the position of the at least one unexposed frame based on information obtained from said first memory means;

first selecting means for selecting the second winding control mode;

second selecting means for selecting the second rewinding control mode when the second winding control mode has been selected by said first selecting means; and

prohibiting means for prohibiting said first selecting means from selecting the second winding control mode when information obtained from said second memory means indicates a rewinding state of the film.

15. A camera according to claim 14, wherein the second winding control mode causes said film winding means to wind the film by two frames.

16. A camera according to claim 14, further comprising display means for displaying operations of the first winding control mode and the second winding control mode.

17. A camera comprising:

film winding means for performing electrically-driven winding of a film;

film rewinding means for performing electrically-driven rewinding of the film;

control means for causing said film winding means to wind the film whereby at least one film frame is left unexposed, and for causing said film rewinding means to rewind the film whereby the film is stopped at the position of the at least one unexposed frame, to expose the at least one unexposed from at the time of the rewinding;

first memory means for memorizing an amount of film wound out from a film cartridge;

second memory means for memorizing the number of exposed frames of film; and

display means for displaying position information of the film based on information obtained from said first memory means and for displaying the number of exposed frames of film based on information obtained from said second memory means.

18. A camera according to claim 17, wherein said control means causes said film winding means to wind the film by two frames.
