Abstract

PURPOSE:To simplify the operation and to enhance the working efficiency by forming a macro lens part as a separate part and forming a mirror section and the macro lens part as an independent unit. CONSTITUTION:A film is lighted by a light source 8 and the lighting light is formed on an imaging device of a conversion section 1 via a reflection mirror 3, a macro lens 11 and an image pickup main lens 2. Then the conversion section 1 converts an optical image formed by a lens system comprising the image pickup main lens 2 and a micro image pickup lens 11 into a video signal and the video signal is sent to a television receiver and a film image is watched through a television screen. On the other hand, in the case of an object other than the film such as a printed matter or a scenery to be picked up, the image pickup main lens 2 is used for pickup while its aberration is compensated so that the image pickup for a remote distant object is attained by removing the unit 12 having the macro image pickup lens section 11 and the reflection mirror 3 from the main body device. In this case, the reflection mirror 3 is tilted to reflect a luminous flux center 4 by 90 deg..

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 device for converting a filmed image into a video signal so that it can be viewed on a television.

[0002]

2. Description of the Related Art It is convenient if not only an image taken on a silver salt film (negative or positive) can be enjoyed as a print photograph but also directly through a TV screen. Such conventional devices are shown in FIGS. 6 and 9. When the film held by the film holder 7 is inserted into the film guide 6, the film is illuminated by the light source 8 and the reflector 9 and photographed by the photographing lens 2. Then, after being converted into a video signal, the image of the film can be viewed on a commercially available television screen.

[0003]

However, in such a device, the layout of the light source and the film photographing lens is linear, and it is necessary to take a sufficient height, and there are the following drawbacks.

When a subject other than film, such as a printed matter or a landscape, is to be photographed, first, the film holding portion or the film holder on the optical axis is removed, while the taking lens designed for macro is used for other purposes. It was necessary to replace the taking lens with a taking lens or install a conversion lens in front of the taking lens designed for this macro.

An object of the present invention is to provide an image taking apparatus made in view of the above problems.

The apparatus characterized by the present invention holds a reflecting mirror for bending the light of an illuminated film by about 90 ° and a lens portion for macro photography which is located on the optical path bent by the reflecting mirror. A detachable unit, and a main photographing lens is provided in a light emitting portion of the lens unit in a state where the unit is attached to the apparatus.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are an exploded perspective view and an overall perspective view of an apparatus according to the present invention. FIG. 3 is a cross-sectional view of a main part of the device according to the present invention. In the figure, 1 is a conversion unit having an image pickup device for converting an optical image into a video signal, 2 is a photographing main lens, 12 is a reflecting plate 3 and a macro photographing lens 11 which are detachable from the main body. It is a unit section.
Reference numeral 7 is a film holder, 6 is a film guide into which the film holder 7 is inserted and guides a film, 8 is a light source, and 9 is a reflector.

Under such a structure, the film is illuminated by the light source 8, and this illumination light is imaged on the image pickup device of the conversion unit 1 via the reflection mirror 3, the macro lens 11, and the photographing main lens 2. . The conversion unit converts the optical image formed by the lens system of the photographing main lens and the macro photographing lens into a video signal and sends the video signal to the television receiver. Then, the image of the film will be viewed on the TV screen.

On the other hand, in the case of a subject other than film, for example, a printed matter or landscape photography, the main lens for photography can be used for a long-distance object by removing the previous unit having the lens portion for macro photography and the reflection mirror from the main unit. Since the aberration state is compensated so that the subject can be photographed, it is possible to favorably photograph such an object.

2A and 2B are perspective views of the entire apparatus. FIG. 2A shows a state where a film is photographed, and FIG. 2B shows a state where normal photographing is performed, that is, a state where the unit portion 12 is removed. FIG. 3 is a cross-sectional view of a main part, in which the reflection mirror 3 is inclined so as to reflect the light beam center 4 by 90 °.

4, 5 and 6 are exploded side views of essential parts showing another embodiment of the present invention. In Example 2 shown in FIG. 4, the main photographing lens and the conversion unit are installed at the bottom, the optical axis extends upward, and the macro lens 11 is independent on the optical axis.
Further, a mirror 3a is provided at the end of the optical axis at an angle of 45 degrees from the horizontal, and this mirror 3a is a single unit 12a together with the macro lens 11a. The mirror 3a converts the optical axis in the horizontal direction by 90 degrees, and is capable of photographing an image of the film which is held by a film holder 7a which is vertically grounded on the upper side and whose front and back sides are reversed.

In Example 3 shown in FIG. 5, a taking lens 2b and a converting section 1b are horizontally installed on the bottom, an independent macro lens 11b is provided on the optical axis thereof, and a mirror is provided at the tip of the optical axis. 3b is arranged at an angle of 45 degrees from the horizontal,
Independent unit 1 with macro lens 11b
It is 2b. The mirror 3b is 90 degrees in the vertical direction of the optical axis.
The film holder 7b which has been converted to a horizontal position and installed horizontally on the upper side
It is possible to take an image of the film, which has been held in the reverse side of the film.

In the fourth embodiment shown in FIG. 6, a film guide 6c, a light source 8c, and a reflector 9c are vertically installed on the bottom, and a mirror 3c is arranged 45 degrees from the horizontal between the optical axes in the horizontal direction.
It is arranged at an angle of 90 degrees and converts the optical axis 90 degrees in the vertical direction,
Further, there is a macro lens 11c at the tip of the optical axis, and it is an independent unit 12c together with the mirror 3c. Then, the film can be photographed by the photographing main lens and the macro lens 1c which are vertically installed on the upper portion.

[0015]

As described above, according to the present invention,
The following effects can be obtained by configuring the mirror part and the macro lens part as one independent unit with the macro lens part as a separate body. In addition to film shooting, when shooting flat originals such as printed matter, three-dimensional objects, and landscapes, it is possible to shoot simply by removing the unit in which the mirror section and the macro lens section are integrated. Therefore, the operation is simple and the working efficiency can be improved.
