Abstract

A photographic camera converting a captured optical image to a series of electronic signals is disclosed comprising a recording mechanism to record these signals including a recording head which executes transverse scanning movements with reference to a magnetic record medium so that at least one scanning movement corresponds to each image. The magnetic record medium is contained within a cassette that is removable from the camera body.

Claims

1. A photographic camera having means for converting an optical image into a series of electronic signals comprising:

means for recording signals on a magnetic record medium including a recording head movable in transverse scanning movements relative to said record medium so that one scanning movement corresponds to each image;

a camera shutter;

an operating mechanism for opening and closing said shutter, said camera being adapted to transmit an optical image to said converting means when said shutter is open;

a removable cassette containing said magnetic record medium;

an operating mechanism mounted in said camera for moving said magnetic record medium in discrete steps lengthwise relative to said transverse scanning movements of said recording head, said cassette having an aperture permitting access for moving said magnetic record medium contained in said cassette and a transverse aperture permitting access of said recording head for recording while tape is confined within the cassette; and

means for synchronizing the operation of said recording head, shutter and magnetic recording medium.

2. A photographic camera according to claim 1, said cassette having a shutter for blocking said apertures and access to the magnetic record medium when the cassette is removed from the photographic camera.

3. A photographic camera having means for converting an optical image into a series of electronic signals comprising:

means for recording signals on a magnetic record medium including a recording head movable in transverse scanning movements relative to said record medium so that one scanning movement corresponds to each image;

an operating mechanism for said recording head;

a camera shutter;

an operating mechanism for opening and closing said shutter, said camera being adapted to transmit an optical image to said converting means when said shutter is open;

common means to place said operating mechanisms for said shutter and said recording head in set condition whereby said shutter is prepared to open and said recording head is prepared to effect a scanning movement;

a removable cassette containing said magnetic record medium;

an operating mechanism mounted in said camera for moving said magnetic record medium in discrete steps lengthwise relative to said transverse scanning movements of said recording head;

said operating mechanism for moving said magnetic record medium including a toothed driving member and said magnetic recording medium including holes cooperating with teeth of said driving member.

4. A photographic camera according to claim 3 in which said operating mechanism for said recording head includes a spring, lever means to place said head operating mechanism in set condition, and means for releasing said head operating mechanism so that said spring effects the transverse scanning movement of said recording head.

5. A photographic camera according to claim 4 in which said lever means is connected to place said operating mechanisms for said shutter and said recording means in said condition.

6. A photographic camera having means for converting an optical image into a series of electronic signals comprising:

means for recording signals on a magnetic record medium including a recording head movable in transverse scanning movements relative to said record medium so that one scanning movement corresponds to each image;

an operating mechanism for said recording head;

a camera shutter;

an operating mechanism for opening and closing said shutter, said camera being adapted to transmit an optical image to said converting means when said shutter is open;

common means to place said operating mechanisms for said shutter and said recording head in set condition whereby said shutter is prepared to open and said recording head is prepared to effect a scanning movement;

a removable cassette containing said magnetic record medium;

an operating mechanism mounted in said camera for moving said magnetic record medium in discrete steps lengthwise relative to said transverse scanning movements of said recording head, said cassette having apertures permitting access for moving said magnetic record medium contained in said cassette;

said cassette including a shutter for blocking said apertures and access to the magnetic record medium when the cassette is removed from the photographic camera.

7. A photographic camera according to claim 6 in which said operating mechanism for said magnetic record medium includes an escapement device to feed the magnetic record medium in discrete steps to regulate the spacing of the recording tracks.

8. A photographic camera having means for converting an optical image into a series of electronic signals comprising:

means for recording signals on a magnetic record medium including a recording head movable in transverse scanning movements relative to said record medium so that one scanning movement corresponds to each image;

a camera shutter;

operating mechanisms for said shutter, said recording means and said magnetic record medium; and

means to place said operating mechanisms for said shutter and recording means in set condition whereby said shutter is prepared to open and said recording head is prepared to effect a scanning movement and for synchronizing the release thereof.

9. A photographic camera according to claim 8 in which said operating mechanism for said shutter is movable through an operating stroke and including means for releasing said recording means from set condition at the end of the shutter mechanism operating stroke.

10. A photographic camera according to claim 8 in which said operating mechanisms include independent reel means, setting lever means for rotating said reel means and placing the same in set condition, a cable connected to said recording head and wound on one of said reel means and a cable connected to said shutter and wound on the other of said reel means, and springs associated with said cables for moving said head and shutter through an operating stroke.

11. A photographic camera according to claim 10 in which friction clutches are included in said reel means for transmitting movement of said setting lever means to place said reel means in set condition.

12. A photographic camera according to claim 10 in which said operating mechanisms include pawl devices carried by the reel means cooperating with a manual control rod for operating the camera having notches to release the pawl devices.

13. A photographic camera according to claim 12 in which said pawl devices cause sequential release of said shutter and recording head and synchronize the operation thereof.
