Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing device, and more particularly, to a reproducing photographing device for photographing an image of an image recording medium such as a photographed film.

[0002]

2. Description of the Related Art A conventional reproducing photographing device photographs, for example, a positive film photographed by a still camera or reversely photographs a negative film, and converts the photographed image into an electric signal by an image pickup device such as a CCD. It is then used for viewing on TV screens.

A conventional example of the above-described image pickup apparatus will be described below with reference to FIGS. 6 and 7.

Conventionally, as shown in FIGS. 6 and 7, the layout is arranged in a linear direction. Figure 6
FIG. 7 is an exploded perspective view of a conventional first device configured in a vertical (vertical) direction, and FIG. 7 is an exploded perspective view of a conventional second device configured in a horizontal (horizontal) direction. These devices have imaging systems 1d and 1e, to which optical systems 2d and 2e are connected. There are film guides 6d and 6e having central opening windows 5d and 5e whose centers coincide with the optical axes 4d and 4e and film holders 7d and 7e holding the films 10a and 10e. Then, on the back surface of the film guide, there are light sources 8d and 8e, and there are reflectors 9d and 9e.
Light is directed to the opening windows 5d and 5e by e.

[0005]

However, in the above-mentioned conventional example, since the layout of the light source, the film guide, and the image forming optical system is linear, there are the following problems.

(A) When placed vertically (vertical position), the ground contact area becomes small. Therefore, it lacks stability when placed.

(B) When placed in a vertical position (vertical position), the main body comes close to the human face to be operated during operation. Therefore, the operability is poor.

(C) When placed horizontally (horizontal position), it takes up a considerable amount of space because of the large ground contact area.

(D) Since the total length becomes long, it becomes large as a whole.

Therefore, an object of the present invention is to provide an image pickup apparatus which solves the problems of the prior art.

[0011]

In the photographing apparatus of the present invention, the optical axis of the photographing film is converted into a right angle by interposing a mirror between the object film at the photographing position of the photographing apparatus and the imaging optical system. The imaging optical system is laid out at right angles to the orthogonal axis of the film surface.

The image pickup apparatus constructed according to the present invention has the advantages that it is smaller than the conventional apparatus as a whole and is easy to operate.

In the figure, 1 is an image pickup system including a photoelectric conversion element such as CCD, 2 is an optical system connected to the image pickup system 1, 3 is a mirror for converting the optical axis 4 into a right angle, 6 is an opening window 5 in the center. A film guide 7 is inserted and holds a film holder 7 holding a film 10 with the front and back reversed, a light source 8 and a reflector plate 9. FIG. 2 is a side view showing the layout of these components. As is clear from this drawing, the film guide 6, the light source 8 and the reflection plate 9 are horizontally installed at the bottom, and the mirror 3 is arranged on the vertical optical axis at an angle of 45 degrees from the horizontal, and the optical axis is horizontal. The image is converted by 90 degrees in the direction and photographed by the imaging optical system installed horizontally on the upper side.

In the first embodiment shown in FIG. 3, the imaging optical system (imaging system 1a, optical system 2a) is vertically installed at the bottom,
The mirror 3a is arranged on the optical axis at an angle of 45 degrees from the horizontal, the optical axis is converted 90 degrees in the horizontal direction, and the front and back sides held by the film holder 7a vertically installed on the upper side are reversed. You can take a picture of the film.

In the third embodiment shown in FIG. 4, the image pickup system 1b and the optical system 2b are horizontally installed at the bottom, and the mirror 3b is arranged between the optical axes in the horizontal direction at an angle of 45 degrees from the horizontal. The optical axis is converted by 90 degrees in the vertical direction, and an image of the film, which is held on a film holder 7b horizontally installed on the upper side and whose front and back sides are reversed, can be photographed.

In the fourth embodiment shown in FIG. 5, a film guide 6c, a light source 8c, and a reflector 9c are vertically installed on the bottom, and a mirror 3c is arranged between the horizontal optical axes of the film guide 6c and the reflection plate 9c.

Images can be taken by the imaging optical system (optical system 2c, imaging system 1c) installed vertically on the upper part.

[0019]

As described above, the photographing apparatus of the present invention having the mirror for changing the optical axis has the following effects.

(1) Where the reflector, the light source, the film guide, and the imaging optical system are arranged in a straight line on the optical axis, the total length becomes long, whereas the present invention makes the whole compact. You can

(2) In the case where the reflector, the light source, the film guide, and the image forming optical system are arranged in a straight line on the optical axis thereof, and when this is arranged vertically in the vertical direction, the apparatus of the present invention is The large ground contact area provides good stability when placed. In addition, since the main body does not come close to the face during operation, operability is good.

(3) When a mirror is used, the image is reversed, but since the subject is a film image, when the film is mounted on the film holder, the film is mounted on the film holder with the front and back reversed. The effect can be exhibited without providing the function of electrically or optically reversing the mirror image, that is, without increasing the manufacturing cost.
