2. Description of the Related Art FIGS. 9A and 9B show a schematic structure of a conventional image pickup apparatus. FIG. 9A is a front view and FIG. 9B is a front view when a printed matter is photographed. In FIG. 9, 1 is a light source for photographing an optical film, 2 is an optical film, 3 is a printed matter, 4 is an optical block, 5 is an imaging block, 12 is another light source for illuminating a printed matter, 16 is an optical attachment, and 17 is photographing. The mirror 19 is a main body of the image pickup apparatus.

Conventionally, in an image pickup device capable of photographing an image formed on an optical film and photographing a printed matter using the image photographed on a silver salt film (negative or positive) as a print photograph, At the time of photographing the image formed on the optical film 2, the optical film 2 is illuminated by the optical film photographing light source 1 arranged at a position facing the photographing optical system with the optical film 2 interposed therebetween, as shown in FIG. The light transmitted through the optical film 2 is guided to the photographing optical system in the optical block 4, and the image formed by the image pickup device in the image pickup block 5 is photographed.

When photographing a printed matter, as shown in FIG. 9B, the photographing plane is switched by an operation such as removing the optical attachment 16 shown in FIG. 9A, and the printed matter 3 on the printed matter installation surface is changed. The image of (1) is taken into the photographing optical system in the optical block 4, and the image formed by the image pickup element in the image pickup block 5 is photographed.

FIG. 10 shows an example of a conventional image pickup apparatus. FIG. 10A is a front view with an optical unit, and FIG. 10B is a front view without an optical unit. is there.

In FIG. 10, reference numeral 21 denotes an optical block, 2
2 is an imaging block, 23 is a signal processing board, 24 is an optical unit, 24a is a lens section, 24b is a mirror section, 26
Is a light source, 27 is a reflector, 28 is a film, 29 is a film holder, and 30 is a film guide. The apparatus shown in FIG. 10 has a mirror section 24b and a lens section 24a, and the unit that is attachable to and detachable from the main body is configured as one independent optical unit 24 for film shooting.

With the above construction, it is possible to photograph a film or the like while the optical unit 24 is worn, and to photograph a three-dimensional object or landscape with the optical unit 24 removed. .

[0008]

However, in the above-mentioned conventional example, the structure is illuminated by the built-in light source at the time of photographing the image formed on the optical film, but regarding the illumination at the time of photographing the printed matter, No consideration was given.

Therefore, when photographing a printed matter, the photographer
There was a drawback that it was necessary to prepare a separate light source and illuminate the printed matter. Further, even when the light source for photographing the printed matter is also built in the apparatus at the same time, since there are plural light sources in the apparatus, there is a drawback that the apparatus becomes complicated, large, and costly. It was

Furthermore, in the conventional example shown in FIG.
Since a mirror is used to capture an image of the film, the device can be made compact, but there is a drawback that a mirror image is output. That is, when the subject is seen through the mirror as shown in FIG.
That is, the normal subject is observed as an image in which the left and right sides are reversed as shown in FIGS.

[0011] Usually, measures are taken such as inverting the front and back of the film and providing a switch for outputting a mirror image. However, these measures also have their respective drawbacks.

When the film is installed upside down.

This method is based on the above-mentioned FIGS. 10 (a) and 10 (b).
As shown in, it is a simple and effective measure that does not require a special device or mechanism and simply reverses the film installation.

However, such a method of outputting left-right reversed images from the beginning causes a problem when the image (film) is moved in order to obtain an output of an arbitrary composition. In other words, if you move the actual film to the right, the image output from the device will move to the left, which will be a very unnatural state, which makes it difficult for the user to obtain the desired composition, and becomes an inconvenient device. Of.

When a switch for outputting a mirror image is provided.

An example is shown in FIGS. 11 (a) and 11 (b). Figure 11
Shows another example of a conventional image pickup apparatus. FIG. 7A is a front view at the time of film shooting, and FIG. 9B is a front view at the time of landscape shooting.

In the case of FIG. 11A, the output changeover switch 31 which is a mirror image output is ON, and in the case of FIG. 11B, the output changeover switch 31 which is a mirror image output is OFF.

The normal output is output during landscape photography, and the mirror image of the image is output during film photography because it is a mirror image through a mirror. In this case, the installation state of the film is normal, and the actual moving direction of the film matches the moving direction of the output image.

However, the user is required to perform a troublesome operation of switching the switch ON / OFF each time the optical unit is attached / detached. Further, if this operation is forgotten, an unintentional left-right image is output.

The present invention has been made in order to solve the above-mentioned problems. A user can obtain a desired composition with a single light source in the image pickup device to downsize the entire device and with a simple structure. An object of the present invention is to obtain an image pickup apparatus which can be switched between a normal output and a mirror image output according to attachment / detachment of an optical unit.

[0021]

In order to achieve each of the above objects, the image pickup apparatus of the present invention illuminates a printed matter with a light source for photographing an optical film and shoots the printed matter, particularly for the above purpose. For that purpose, the optical film installation surface and the printed material installation surface are arranged at an angle of less than 90 ° as required, and for the purpose of (1), a switch for detecting attachment / detachment of the optical unit is provided. The output signal is corrected based on the detection signal, and the output signal can be corrected by switching between the normal output and the mirror image output.

[0022]

According to the present invention, the printed matter is illuminated by the light source for photographing the optical film, so that both the optical film and the printed matter can be illuminated by a single light source.

At this time, if the angle between the installation surface of the optical film and the installation surface of the printed matter is less than 90 °, a simple structure can be achieved without using a member such as a mirror.

Furthermore, according to the present invention, by providing a detection switch for attaching and detaching the optical unit, the normal output and the mirror image output of the image can be switched based on the output of this switch.
