DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing apparatus for recording and storing image information of a subject such as documents, documents, drawings, checks, stock certificates, bills, and slips.

[0002]

2. Description of the Related Art The above-described photographing apparatus can be roughly classified into an analog recording apparatus and a digital recording apparatus.

(1) Analog recording method This is a method for recording and storing object image information by forming an image on a photosensitive recording medium by image forming means. As a typical example, there is a microfilm system in which subject image information is reduced and image-projected onto a photographic film as a photosensitive recording medium, and the resulting image is recorded and stored. Microfilm is excellent in preservability, high density and evidence ability of recorded images. In some cases, subject image information is imaged and projected on a photosensitive recording medium other than a photographic film, for example, an electrophotographic photosensitive member or the like, and is recorded and stored as a copy of the same size or reduced size.

(2) Digital Recording Method (Electronic File Method) Subject image information is image-formed and projected on an image photoelectric reading means such as an image sensor by an image forming means, and is converted into an electric pixel signal (time-series electric digital pixel signal). It reads the information, stores the photoelectrically read information in an electronic information recording medium such as a magnetic recording medium or an optical disk, and records and saves the information. For information reproduction, target recorded image information is searched and converted into an optical signal and output as a hard copy of image information by a printer, or output as image information on a display device such as a CRT. This digital recording method is excellent in quick searchability (callability) and editability of the recorded image information.

[0005]

By the way, a recording medium of subject image information is created by the above-mentioned photographing apparatus,
When implementing the management / utilization system, two or more recording media on which the same subject image information is recorded (or stored) are created and one is stored and managed as a backup recording medium (sub recording medium). However, it is advantageous in terms of a recording medium management / utilization system to use the other as a recording medium to be used (main recording medium). For example, a backup recording medium is created and stored and managed as a microfilm with excellent storability.
For example, it is prepared as an electronic information recording medium having excellent editability and the like, and is usually used.

However, in order to create two or more recording media on which the same subject image information is recorded by a conventional photographing apparatus, the same photographing operation is repeated a required number of times on the recording medium, resulting in poor work efficiency.

For example, when one is to be used as a recording medium for analog recording such as a microfilm and the other is to be prepared as an electronic information recording medium for digital recording such as a magnetic recording medium and an optical disk, an analog device as an independent device independent of each other is required. Having two devices, a recording-type photographing device and a digital recording-type photographing device, would require each of them to perform a photographing operation, which would also result in poor work efficiency. In addition, having two devices would require equipment costs, installation space, and work. There is a problem in sex etc.

Accordingly, an object of the present invention is to provide a photographing apparatus capable of producing two or more recording media in which the same subject image information is recorded in one photographing operation.

It is another object of the present invention to provide a photographing apparatus which can prepare one of the plurality of recording media as a recording medium for analog recording and the other as an electronic information recording medium for digital recording.

It is a further object of the present invention to provide the above-mentioned photographing apparatus which is compact and low-cost as a whole, and therefore has no problems such as equipment cost and installation space.

By using the plurality of recording means as recording means having different recording methods, the same subject image information can be simultaneously created as two or more recording media having different recording methods. For example, one of the plurality of recording media can be simultaneously created as a recording medium for analog recording, and the other as an electronic information recording medium for digital recording. In order to create such a recording medium, the recording methods are different from each other. Problems such as equipment costs, installation space, workability, and the like when a plurality of photographing apparatuses are held as independent individual apparatuses are solved.

The recording means can be detachably attached to the main body of the photographing apparatus, and can be used in various photographing modes by combining and using recording means having the same or different recording methods.
