Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photo video reproducing apparatus, and more particularly to a photo video reproducing apparatus capable of displaying a negative film image on a television receiver with a film sheet having a negative film inserted as it is.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, as a reproducing apparatus for projecting a filmed negative film (for example, 35 mm film) F on a home television receiver (not shown),
A photo video playback device 50 is known.

In this photo video reproducing apparatus 50, a photographing section 52 is formed in an intermediate portion of a vertically long reproducing apparatus main body 51, and an upper upper body 51a and a lower main body 51b forming a lower pedestal.
And are formed. A lens 53 for photographing is arranged on the lower surface of the upper main body 51a, and an image processing device (not shown) and the like are housed inside the upper main body 51a. A light source (not shown) is provided on the lower main body 51b so as to project light upward.

Then, the negative film is taken out from a film sheet (not shown) in a state where the negative film is inserted at a DPE store and loaded into a dedicated carrier 54, and in this loaded state, it is formed on the lower main body 51b. Insert from the carrier insertion port 51c. In this state, the light source is turned on to make the image on the negative film F clear, and this image is taken by the lens 5
The image is picked up via the image pickup device 3, and after predetermined image processing, it is displayed on the television receiver.

[0005]

However, in the conventional photo-video reproducing apparatus 50, each time a strip-shaped negative film (35 mm film is normally cut every 6 sheets) is displayed on the television receiver, The negative film must be newly loaded in the dedicated carrier 54, and a plurality of strip-shaped negative films cannot be continuously displayed on the television receiver. Further, since it is vertically long, it is impossible to store it in an AV rack that stores VTRs and the like.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a translucent film sheet into which a photographic film is inserted, a conveying device for conveying the film sheet, and a tip of the conveying device. A drum that is provided with a light source inside, is wound around the film sheet S, and stops at a predetermined position;
And a camera that captures an image of the photographic film projected by the light source through the film sheet.

Further, the camera is constructed so as to be moved in the direction of the central axis of the drum. Further, a strip-shaped photographic film is inserted into the film sheet, and the camera is configured so that each frame of the strip-shaped photographic film can be photographed.

[0008]

According to the present invention, a photographic film is inserted into a translucent film sheet. A film sheet containing a photographic film is conveyed by a conveying device, and the film sheet is wound around a drum. In this winding state, the light source is turned on and the image of the photographic film is taken by the camera. The image picked up by the camera is negative-positive inverted and displayed on the television receiver.

Further, the camera captures an image on a photographic film while moving in the direction of the central axis of the drum.

As shown in FIGS. 1A and 1B, a slender fluorescent lamp 8 as a light source is disposed inside the drum D in the central axis direction, and the fluorescent lamp 8 is fixed to a casing K. , Fluorescent light 8
A light condensing member 9 for condensing light to the right (camera direction) is disposed around the.

A video camera C for picking up a color image is arranged on the right side of the drum D, and the video camera C has a drive motor (not shown) on the guide rails 11a and 11b in the central axis direction of the drum D. Thus, the negative film is moved one frame at a time. Video camera C
The lens C ₁ of the drum D is stopped to rotate in the vertical position.
The video camera C is arranged so as to face one side surface, and the video camera C can be finely moved vertically and horizontally by a fine movement device (not shown).

An openable and closable lid 12 is disposed on the front side surface of the casing K, and guide walls 12a and 12b are formed on the left and right sides of the lid K to prevent lateral shake of the inserted film sheet S _N. There is. One pulley 13 around which the belt T is stretched is arranged near the base of the lid 12 in the opened state, and the other pulley 1 is arranged near the lower ends of the guide members 6 and 7.

In case of frame advance (step S1
1; Yes), and the frame advancing switch I ₂ is pressed to turn on the muting circuit 23 (step S1).
2) While the camera C is moving, the television receiver TV is muted so that an unnecessary image (for example, an image captured while moving) is not displayed. When the frame advance switch I ₂ is pressed, the camera C moves by one frame (step S1
3) After completion of the movement, the muting circuit 25 is turned off, and the next (second frame) image is displayed on the television receiver TV.
When frame advance is not performed in step S11 (step S11; No), the first frame image is continuously displayed on the television receiver TV (step S10).

When one negative film is finished and the film is fed to project the second film (step S
15; Yes), when the film feed switch I ₃ is pressed down, the muting circuit 25 is turned on, the drum D is rotated, and after the rotation is completed, the muting circuit 25 is turned off and the next image is displayed (step S10).

When the film is not advanced in step S15 (step S15; No), the first frame image is continuously displayed on the television receiver TV. To end the operation, the film discharge switch I ₄ is pressed to reverse the drum D and reverse the belt T to discharge the film sheet S _N from the photo video playback device P to the outside (step S19). ..

As described above, the images of a plurality of negative films are sequentially displayed on the television receiver TV for each frame of each negative film. Further, when it is desired to finely adjust the projected position of the image on the screen of the television receiver while the negative film image is projected on the television receiver TV, the frame feed direction fine adjustment switch I ₉ and the camera angle adjustment switch I _By adjusting ₅ and zoom adjustment switch I ₆ as appropriate,
A desired image may be displayed on the television receiver TV.

When the image of the negative film is recorded on the video disc, the video disc is loaded into the video disc drive B and the steps S1 to S18 are performed.
During this operation, the video recording switch I ₆ may be pressed to record a negative film image on the video disc. When the image on the negative film recorded on the video disc is reproduced and displayed on the television receiver TV, the video disc is loaded into the video disc drive B and the video reproduction switch I ₈ is depressed. Play it back.

In this embodiment, the case of a 35 mm film has been described, but it goes without saying that it can be applied to films of other sizes. Although the case of the negative film has been described, it is needless to say that it has a negative / positive reversal function and can be applied to the case of a positive film.

Further, the drum D on which the negative film is wound
Since the camera is arranged horizontally opposite to the camera C, the height of the photo video reproducing device can be kept low.
It can be stored in the rack of AV equipment.

Further, although the drum cross section is square in this embodiment, it may be pentagonal or hexagonal.
