Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus, and more particularly to an image reproducing apparatus for photographing a negative film or a positive film with an electronic camera.

[Conventional technology]

FIG. 3 is a side sectional view of a conventional video reproducing apparatus. In FIG. 3, an image reproducing adapter 1 has a lamp 3 inside, a film 7 is movably mounted on a base 5 at a central upper portion of the lamp 3, and an image of the film 7 is collected on the upper portion. The lens 6 is provided. The shape of the upper portion of the video playback adapter 1 is concave and convex with the electronic camera 9 and is fitted. The lamp 3, the film 7, and the electronic camera 9 are configured to be located on the optical axis.

[Problems to be solved by the invention]

As described above, in the conventional example, when the film 7 is attached to the video playback adapter 1 and the power supply 8 is turned on and the lamp 3 is left for a long time while being turned on, the film 7 is It will be deformed. Further, there is a problem that the life of the lamp 3 is significantly shortened.

The present invention has been made in view of the above circumstances, and in an image reproducing apparatus that captures an image of a film with an electronic camera, protecting the film from lighting means for illuminating the film and extending the life of the lighting means. It is an object of the present invention to provide an image reproducing apparatus capable of performing the above.

[Means for solving the problem]

The present invention is directed to an image reproducing apparatus that captures an image of a film with an electronic camera, and illuminating means for illuminating the film.
In response to a signal from the electronic camera, when there is no unrecorded portion in the recording medium of the electronic camera, the image reproducing apparatus has a light-off means for turning off the lighting means.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side sectional view of an image reproducing apparatus according to an embodiment of the present invention, and FIG. 2 is a control block diagram for controlling the operation of the lamp in FIG. In the drawing, the same or corresponding components as those in the conventional example are denoted by the same reference numerals, and the description will be partially repeated.

In FIG. 1, reference numeral A denotes recording means, which comprises an electronic still camera (hereinafter referred to as an electronic camera) 9, and means for recording a negative film and a positive film (hereinafter collectively referred to as a film) 7 with the electronic camera 9. is there. B is an illuminating means, which is constituted by the lamp 3 and illuminates the film 7. C is a switching means for switching the lighting means B from the recording means A under a certain condition (described later).
Reference numeral 1 denotes a video reproduction adapter (body), 2 denotes a contact on the video reproduction adapter side, and 10 denotes a contact on the electronic camera side. The electronic camera 9 is of a recording and reproducing type.

Next, the operation of this embodiment will be described with reference to FIGS.

First, description will be made focusing on a case where the constant condition in this embodiment is that the operation switch 22 of the recording means A does not change for a fixed time. Electronic camera 9 to video playback adapter 1
The main body-side contact 2 and the electronic camera-side contact 10 are connected to each other, and the operation switch 22 (the second
The REC switch (SW) in FIG. 2 is turned on, and the control circuit 21 turns on the lamp switch 23 to enter a recording standby state. When the REC SW is turned on, the control circuit 21 starts an internal timer of the control circuit 21. Thereafter, when there is no change in the operation switch 22 which is a certain condition for a certain time, the control circuit 21 disconnects the lamp switch 23. , Lamp 3 goes out. If there is a change in the operation switch 22 within a certain period of time, an internal timer (not shown) is set and the above operation is performed.

When the operation switch 22 changes after the lamp 3 is turned off, the control circuit 21 turns on the lamp switch 23 and the lamp 3 is turned on.

Next, a case where the certain condition in this embodiment is that there is no recording medium will be described.

When the control circuit 21 detects that the recording medium 25 is loaded through the recording / reproduction circuit 24 while the electronic camera 9 is connected to the video reproduction adapter 1 and the REC SW of the operation switch 22 is turned on. The lamp switch 23 is turned on to turn on the lamp 3, and when no lamp is loaded, the lamp switch 23 is not turned on and turned off.

Next, a case where the certain condition in this embodiment is that there is no unused portion of the recording medium will be described.

When the electronic camera 9 is connected to the video playback adapter 1 and the REC SW of the operation switch 22 is turned on, the control circuit 21 checks an empty area of the recording medium 25, and when there is an unrecorded portion, a lamp is provided. The switch 3 is turned on to turn on the lamp 3, and when there is no unrecorded portion, the lamp switch 23 is not turned on and turned off.

〔The invention's effect〕

As described above, according to the present invention, in an image reproducing apparatus that captures an image of a film with an electronic camera, the film can be protected from illumination means for illuminating the film, and the life of the illumination means can be extended. is there.
