DESCRIPTION OF THE PREFERRED EMBODIMENTS Details of the photo video camera apparatus of the present invention will be explained below according to the illustrated embodiments.

1 to 3 show a first embodiment of the present invention.

Reference numeral 1 denotes a photo video camera device, which includes a film stage 2 for placing a film, a main body 3 equipped with a lens system, a solid-state image sensor, various circuits, etc., and a lower part of the main body 3 and a film stage. 2 and a base portion 4 which connects them with an appropriate distance between them.

The film stage 2 has a backlight section 5 housed therein, and its light sources 5a, 5a (see FIG. 3).
The illumination light is emitted upward from the light diffusing plate 6 on the upper surface.

Further, a guide portion 7 is attached to the upper surface of the film stage 2 to support a film holder, which will be described later, so as to be slidable in the left-right direction. This guide part 7
is detachably attached to the film stage 2, and a detection means (for detecting whether or not the guide section 7 is attached to the film stage 2)
(not shown) is provided.

As schematically shown in FIG. 1, the main body 3 includes a lens system 8 for photographing a projected image of a negative film or an object, and a lens system 8 for converting the photographed image into a video signal through the lens system 8. A solid-state image sensor 9 and various circuits for processing video signals obtained by the solid-state image sensor 9 are housed in a box-shaped housing 10.

A pair of illumination parts 11, 11 are provided on the left and right sides of the main body part 3, and one end part 12, 1
2 consists of arm parts 13, 13 rotatably attached to the side surface of the main body part 3, and light parts 14, 14 provided at the other ends of the arm parts 13, 13. The illumination units 11, 11 are used as illumination when photographing an object placed on the film stage 2.

Note that the light sections 14, 14 have light sources 15, 1
5 and lenses 16, 16.

Furthermore, when the arm parts 13, 13 are rotated, an appropriate braking force is applied by a means (not shown), and the angle that the arm parts 13, 13 form with respect to the main body part 3 can be adjusted steplessly. It is now possible to do so.

Reference numeral 17 denotes a dial provided on the front of the main body 3, and by rotating this dial, the photographing system consisting of the lens system 8, solid-state image sensor 9, etc. can be freely rotated around its optical axis. is now possible.

Reference numerals 18, 18, . . . are operation switches arranged at the front of the base portion 4, and are provided for trimming, zooming, etc. This includes the lighting switch 18a of the lighting units 11, 11. Incidentally, instead of providing such a lighting switch 18a, if a means for detecting the rotation of the arm parts 13, 13 is provided and the lighting parts 11, 11 are turned on in conjunction with the movement of the arm parts 13, 13, the lighting parts 11, 11 can be turned on. , it is possible to save operational effort.

Reference numeral 19 denotes a video signal output terminal, which is provided on the side surface of the base portion 4.

Reference numeral 20 denotes a film holder shaped like several frames connected in a row in the horizontal direction, and the film holder 20 holds the negative film 21 from the front and back sides thereof.

Furthermore, each frame 20a of the film holder 20
, 20a, . . . are formed in a size large enough to hold one frame of the film, and when the negative film 21 is held between the film holders 20, each screen of the negative film 21 is formed in each frame 20a, 20a, . In response to..., it is now possible to approach it from both the front and back.

The film holder 20 holding the negative film 21 is guided by the guide section 7 of the film stage 2 of the photo video camera device 1, and is supported so as to be movable in the left and right directions on the film stage 2.
When each screen of the negative film 21 faces the light diffusing plate 6 of the film stage 2, an image is projected by a backlight section 5 disposed below.

In such a photo video camera device 1, when taking a frame-by-frame picture of the negative film 21, the film holder 20 holding the negative film 21 is moved to the guide portion 7 as shown by the two-dot chain line in FIG. and place it on the film stage 2.

[0023] As a result, one part of the screen of the negative film 21 facing the light diffusing plate 6 is projected by the backlight section 5, and this image is formed on the imaging surface of the solid-state image sensor 9 through the lens system 8 and converted into an electrical signal. After that, the signal is sent to the video signal output terminal 19 via a signal processing circuit. In this case, when photographing the negative film 21, the signal is subjected to inversion (negative-positive conversion) processing, but in this case, the detection means detects that the photographic subject is the negative film 21. The process is automatically performed based on the fact that the guide section 7 is attached to the film stage 2. The backlight section 5 is turned on only while the guide section 7 is attached to the film stage 2.

[0024] Furthermore, the photo video camera device 1 allows
Since the film holder 20 is not used when taking a photograph 22, the guide section 7 is removed from the film stage 2, as shown in FIG.

Then, place the photograph 22 on top of the light diffusing plate 6 so as to cover it (indicated by the two-dot chain line in FIG. Turn the lighting switch 18a from the position shown by the solid line to the position shown by the solid line.
The illumination light from the light sections 14 and 14 is applied to the photograph 22, and the arm sections 13 and 13 are turned on so that appropriate brightness can be obtained.
Adjust the angle.

Normally, by adjusting the rotation angles of the arms 13, 13 so that the illumination light is applied to the object from above at an angle of approximately 45 degrees, it is possible to illuminate the object without causing a shadow.

As a result, the light from the photograph 22 passes through the lens system 8 and forms an image on the imaging surface of the solid-state image sensor 9, and after being converted into an electrical signal, it is sent to the video signal output terminal 19 via a signal processing circuit (not shown). That will happen.

It should be noted that since the detecting means determines that the object to be photographed is not a negative film because the guide section 7 is not attached to the film stage 2, no inversion processing is performed on the video signal in this case. Furthermore, it goes without saying that the backlight section 5 is turned off while the illumination section 11 is turned on.

Next, a second embodiment of the present invention will be described.

The photo video camera device 1A according to the second embodiment differs from the first embodiment in that the illumination section and the backlight section are also used. Therefore, we will mainly explain the differences, and parts that have the same function as each part shown in the first embodiment will be explained by giving the same reference numerals as those given to each part in the first embodiment. Omitted.

FIGS. 4 and 5 show the situation when a photograph 22 is projected in the photo video camera device 1A. In this case, since the film holder 20 is not necessary, the guide section 7 is placed on the film stage during photographing. 2 is the same as in the first embodiment.

As shown in the figure, the illumination parts 11A, 11A are attached to the left and right side surfaces of the main body part 3, and include bendable arm parts 23, 23, and a substantially flat box having a parallelogram shape when viewed from the front. It is composed of light parts 24, 24 each having a shape.

[0033] The arm portions 23, 23 have one end portion 2
5, 25 are rotatably attached to the side surfaces of the main body 3, and have joints 26, 26 at mid-positions.

[0034] The light parts 24, 24 are attached such that one end thereof is rotatable relative to the rotary end part of the arm parts 23, 23.

The other end surfaces of the light parts 24, 24 are formed with openings cut in an inclined shape when viewed from the front, and lenses 27, 27 are respectively fitted to cover the openings. Note that inside the light parts 24, 24, a light source 28,
28 is of course provided.

[0036] Therefore, when displaying the photograph 22, as shown in FIG.
As shown in FIG. 5, the arm parts 23, 23 are bent so that appropriate brightness can be obtained when the lighting switch 18a is turned on and the illumination light from the light parts 24, 24 is applied to the photograph 22. The angles of the joint parts 26, 26 of 23, 23 and the light parts 24, 24 are adjusted. As a result, the photograph 22 is illuminated, and the reflected light passes through the lens system 8 and forms an image on the imaging surface of the solid-state imaging device 9. After being converted into an electrical signal, it is sent to the video signal output terminal 19 via a signal processing circuit. It turns out.

Next, the situation when photographing the negative film 21 in the photo video camera device 1A will be explained with reference to FIGS. 6 and 7. In this case, the film holder 20 is required, so the guide section 7 is attached to the film stage 2 for photographing, and the film holder 20 is supported in a slidable state on the guide section 7, as shown by the two-dot chain line in FIG. do.

Reference numeral 29 denotes a space for arranging the light parts 24, 24, which passes through the base part 4 in the left and right direction as shown in FIGS. 24, 24 can be inserted into this arrangement space 29, the top surface of the film stage 2 is cut out at both left and right ends. At the time of shooting, in this arrangement space 29, the illumination parts 11A, the light part 24 of 11A,
24 are inserted from the left and right sides of the film stage 2, respectively, so that the lenses 27, 27 face each other. At this time, the arm portions 23, 23 are in a fully extended state.

When the lighting switch 18a is turned on in this state, the light emitted from the lens 27 of one light section 24 is reflected by the lens 27 of the other light section 24, as shown by arrows L and L in FIG. Thereafter, the light passes through the upper light diffusing plate 6 and illuminates the negative film 21 from below. The projected image at this time is formed on the imaging surface of the solid-state imaging device 9 through the lens system 8, converted into an electrical signal, and then sent to the video signal output terminal 19 via the signal processing circuit. In this case, it goes without saying that when photographing a negative film, the signal is subjected to inversion processing.

Furthermore, as shown in FIG. 6, the light section 24,
24 inserted into the arrangement space 29, the light section 2
4 and 24 do not obstruct movement of the film holder 20 in the left-right direction.

In the photo video camera device 1A, the illumination parts 11A and 11A are bent into an M-shape when the arm parts 23 and 23 are viewed from the front, as shown in FIG. 5, to illuminate the object to be photographed. or the light section 24 as shown in FIG.
, 24 into the arrangement space 29 and illuminating the negative film 21 from below can be selectively used using the same illumination parts 11A, 11A.
