DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image recording apparatus that records image information of a recording document such as a bill or a check on a recording medium such as a microfilm.

(Prior Art) Conventionally, as this type of image recording device, there is a rotary type micro film camera (hereinafter referred to as a rotary type camera) as shown in FIG. 6, for example. S' is the supply section l provided at the front of the device.
The document is fed from OO to a recording unit 105 inside the apparatus, and the document image of the Q document S' is imaged and exposed to a film as a recording medium (not shown) via an optical system 107 to record the image. The recording medium S' on which recording has been completed in the recording section 105 passes through a conveyance system 103 and is discharged to a discharge section 102 provided at the front of the apparatus for removal. By putting the supply section 100 and the discharge section 102 together at the front of the apparatus in this way, it is possible to conveniently set and take out recording documents.

Furthermore, although not shown in the figure, in order to improve operability for the operator, a film chamber for loading film is also provided at the front of the device.
Some devices were designed to allow film changes and other operations to be performed from the front of the device, as well as the setting of recording manuscripts.

(Problems to be Solved by the Invention) However, in such prior art, the film supply reel and the like in the film chamber are placed vertically, with the exposed surface of the film facing upward. To this end, in order to direct the optical path of the original image of the recording original S' guided from the recording unit 105 inside the apparatus via the optical system 107 to the film exposure surface, a reflecting mirror is provided above the film to bend the optical path. There was a need. Usually, an imaging lens is provided above the film exposure surface, and a reflecting mirror is further disposed above it, so there is a problem in that the structure of the force device becomes large. Therefore, it is possible to save space by lowering the height of the reflective mirror, but this would cause the mirror and lens to be close together, creating the problem that high precision is required for the reflective surface of the mirror. .

The present invention was made in order to solve the problems of the prior art described above, and its purpose is to lower the accuracy requirements by separating the final reflecting means of the optical system from the imaging lens, and to make it compact. An object of the present invention is to provide an image recording device that is large and has excellent operability.

(Means for Solving the Problems) In order to achieve the above object, the present invention arranges a document to be recorded in a recording section inside the device with the document surface facing the front and back direction of the device, and In an image recording apparatus that records an image by sequentially reflecting image light from a document by a plurality of reflecting means to form an image on a recording medium and exposing the image, the recording medium is disposed at the front of the apparatus, and one of the plurality of reflecting means The final reflecting means is arranged behind the recording medium and at the top of all the reflecting means, and the angle between the optical axis of the image light incident on the final reflecting means and the optical axis of the reflected light is an acute angle. It is characterized by being configured as follows.

(Function) Since the final reflecting means is placed at the rear of the apparatus with respect to the recording medium, a large distance can be maintained between the recording medium and the final reflecting means, and the imaging lens is placed in the optical path. Even when the lens is inside, the imaging lens and the final reflection means can be separated by a large distance. Therefore, there is no need to process the reflective surface of the final reflecting means to a high degree of precision, and even if the final reflecting means is at the top position, it is placed at the rear of the device, so there is no need to process the reflective surface of the final reflecting means so that it takes up a large space at the front of the device. There is no problem, and space can be saved.

In FIGS. 1 to 3 according to an embodiment of the present invention, 1 indicates the entire image recording apparatus, In this example, similarly to the conventional example, a rotary camera that records image information of a sheet-shaped object S such as a check as a recording document onto a long microfilm F as a recording medium will be described. This image recording device (2) includes a supply section 2 that roughly supplies a subject S into the device, a discharge section 3 that discharges the subject S after photographing to the outside of the device, and a photographing section 4 as a recording section disposed inside the device. , an upstream conveyance section 5 that connects the supply section 2 and the photographing section 4 , and a downstream conveyance section 6 that connects the photographing section 4 and the discharge section 3 . Then, the subject S transported to the photographing section 4 is imaged and exposed onto a microfilm F via an optical system 7.

The arrangement of each part of the above device is such that the upstream transport section 5 and the photographing section 4 are arranged inside a first frame 51 assembled on the base 8, and the subject S is supplied to the front end 51a of the first frame 51. Section 2 is provided. Further, when viewed from the front of the device, the optical system 7 is mainly arranged on the left side of the first frame 51, and a drive system (not shown) is provided on the right side.

Further, in front of the supply section 2 provided on the front surface of the first frame 51, a film chamber 19 in which the film F is stored is provided. On the other hand, a second frame 61 is attached to the first frame 51 via a rear end hinge lO so as to be openable and closable. is provided. Further, the exterior cover 11 covers the entire device, its lower edge touches the peripheral edge of the base 8, and is attached to the rear end of the base 8 via a hinge 10 at the rear end, so that it can be opened and closed in the forward opening direction. .

FIG. 1 shows the arrangement of the optical system 7. That is, the optical path L' of the image light of the front and back screens of the subject S passing through the photographing unit 4 located approximately in the middle of the inside of the device is determined by a plurality of mirror groups as reflecting means, in this example, the first mirror group. to fourth
It is bent through mirrors 71, 72, 73, and 74, and is imaged and exposed through the left side of the first frame 51 from the center of the apparatus onto a film F provided at the front of the apparatus. That is, first mirrors 71, 71' facing the front and back document surfaces of the subject S are disposed before and after the pair of parallel guide glasses 41, 42 constituting the photographing section 4, respectively. The first mirror 71.71' is arranged at an inclination angle of approximately 45 degrees in the direction of opening from the left side of the device with respect to the guide glass 41.42, and is arranged at an angle of inclination of approximately 45 degrees to guide the optical path of the front and back image light of the subject S. , L' are bent at a substantially right angle from the front-back direction of the device toward the left side.

On the other hand, the second mirror 72 is arranged along the left side of the first frame 51 so as to face the first mirror 71, 71'. This second mirror 72 is the first mirror 71.7.
1' and approximately concave height, with the reflective surface tilted downward and the second
It is also made to face a third mirror arranged below the mirror 72.

Furthermore, a slit 75° 75' is provided between the first mirror 71, 71' and the second mirror 7z to regulate the optical path L'.

On the other hand, the fourth mirror 74 is disposed above the second mirror 72, has a reflective surface facing the third mirror 73, and is inclined in a direction that increases the distance on the front end side with respect to the third mirror 73. ing. The height of this fourth mirror 74 is the first
- The uppermost position among the fourth mirrors 71, 72, 73, and 74, and the longitudinal position of the device is behind the photographing section 4.

With such a group of mirrors, the optical path L' of the image light on the front and back sides of the object 5 is bent at right angles from the front and back direction of the apparatus to the left side of the apparatus by the first mirror 71° 71'.
It is bent downward by the second mirror 72.

The microfilm F as a recording medium is then bent upward by a third mirror 73 and forwardly by a fourth mirror 74 to pass through a photographic lens 76 disposed on the front side of the apparatus. The upper image is formed and exposed, and the front and back images of the subject S are recorded side by side on both sides of the film F.

Here, the angle θ is formed between the optical axis of the incident light from the third mirror 73 to the fourth mirror 74 and the optical axis of the reflected light from the fourth mirror 74 to the film F.

θ' is configured to be an acute angle. With such a configuration, the optical path of the reflected light from the fourth mirror 74 is gradually inclined downward toward the front.

The microfilm F is wound onto a take-up reel 194 from a supply reel 191 wound with unexposed raw film, passing between a capstan roller 192 facing the photographing lens 76 and a pinch roller 193. Then, the image of the subject S is subjected to slit exposure at the capstan roller 192 section.

The feeding speed Va of this microfilm F is the feeding speed of the subject S passing between the guide glasses 41 of the photographing section 4 described above.
^ and synchronized according to the magnification.

The rear part of the film chamber 19 is tilted upward so that the exposed surface of the microfilm F faces the optical path from the fourth mirror 74 at right angles.

On the other hand, 77 is a data display board for displaying data such as the date, etc., and is attached to the side plate of the second frame 61 so that the data can be captured on the microfilm F by a lens 78 that includes data 4, which is separate from the photographic lens 76. It has become.

In the image recording device having the above configuration, the subject S transported from the supply section 2 to the photographing section 4 via the upstream transport section 5 is
The table is illuminated by the illumination lamps 9, 9' arranged before and after it.
The back screen is illuminated. The image light of the front and back images of the subject S is transmitted through the first to fourth mirrors 71, 72, 73.7.
4, the light is sequentially reflected and bent, and is imaged and exposed by an imaging lens 76 onto a film F provided at the front end of the apparatus.

The object S and the film F both move in synchronization with the reduction ratio, and are continuously photographed through the slits 75 and 75'.

Here, the film chamber 19 is arranged at the front of the apparatus like the supply section 2 and discharge section 3 for the subject S.
Loading the film in the same direction as loading and unloading,
Operations such as taking out can be performed, increasing the efficiency of one work.

Moreover, the position of the final fourth mirror 74 is located behind the imaging unit 4 of the apparatus, and there is a large distance between it and the imaging lens 76, so the reflective surface of the fourth mirror 74 can be adjusted with high precision. In addition, since the angle formed by the optical axis of the image incident light on the fourth mirror 74 and the reflected light is made acute,
The optical path from the fourth mirror 74 to the film F is inclined forward and downward, which saves space at the front of the device. Furthermore, in this embodiment, as a result of tilting the optical path from the fourth mirror 74 to the film F, the film chamber 19 can also be arranged with a high slope at the rear. Therefore, when the operator replaces the film from the front side of the apparatus, the supply reel 191 and the take-up reel 194 are attached and detached from diagonally above, making the operation surface easy to see and the operation easier.

In this embodiment, when replacing the film, etc., the exterior cover 11 is attached to the hinge 1 at the rear end as shown in FIG.
By opening the exterior cover 11 forward in this manner, inspection and cleaning of the interior can be performed from the front side of the apparatus. Furthermore, as shown in FIG. 4, the downstream conveyance section 6 can also be opened from the front around the hinge 10, so that work such as jam removal in the upstream conveyance section 5 can be performed from the front of the device. The operator can perform all various operations from the front of the device.

In this example, a rotary camera using film F as the recording medium was explained, but CO2 was used as the recording medium.
The present invention can also be applied to other image recording devices such as facsimile machines and copying machines that employ electrical recording methods such as D or photoreceptor. In short, the present invention can be similarly applied to an apparatus that forms and exposes an image on a recording medium using a plurality of reflecting means for bending the optical path of original image light.

(Effects of the Invention) The present invention has the above-described configuration and operation, and since the final reflecting means is provided at the rear of the apparatus with respect to the recording medium arranged at the front of the apparatus, there is a gap between the recording medium and the final reflecting means. Since it is not necessary to process the reflecting surface of the final reflecting means such as a mirror with high precision, it is possible to reduce costs. Furthermore, since the final reflecting means at the top is placed at the rear of the device, it is possible to save space at the front of the device, and the entire device can be made compact.
