フィルム送り装置に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a film feeding device for a film image information reading device, and particularly to a film feeding device with a simple structure but with high precision without worrying about deteriorating the image information of the film. This invention relates to a film feeding device to be realized.

９−１５６２５１号に記載のフィルム送り装置がある。As a film feeding device that satisfies the above requirements, it was developed in 1975.
There is a film feeding device described in No. 9-156251.

フィルム内の濃度情報を全面に渡り読むことが出来る。An outline of film feeding in the device will be explained using FIG. 3. In the above device, the film is fed by driving rollers 13 and 1.
．． 5 and idle roller 12.14 using roller 12.
This is done by sandwiching the film between the rollers 13 and 13 and between the rollers 14 and 15, and rotating the driving rollers 13 and 15 with a rotary machine. While the film is fed by the film feeding device described above, laser light is scanned over the film by the rotating polygon mirror 3, and the light transmitted through the film enters the detector 5 and is converted into an electrical signal. With this configuration, density information within the film can be read over the entire surface.

。Problems in the above-mentioned film feeding device are the mechanical precision of the roller, the roughness and hardness of the material and surface, and ensuring safety such as not damaging the film. The mechanical accuracy of the rollers directly affects the accuracy of film feeding. For example, if the roller rotation axis is misaligned, the roller will become eccentric.
Accurate film advance is not possible. Furthermore, when the roller becomes longer, problems such as deflection due to the roller's own weight arise. On the other hand, if the surface of the roller is poorly finished or extremely hard, the film may be scratched and the image information within the film may be deteriorated or destroyed. That is, a structure in which the film is sandwiched between rollers and fed by friction between the rollers and the film is not a preferable structure from the viewpoint of ensuring the safety of the film. Furthermore, if the above-mentioned film feeding device is manufactured in consideration of the above-mentioned problems, high precision is required for each component, resulting in a very expensive device. Furthermore, in order to read the information on the entire surface of the film, it is necessary to feed the film using the roller 13 during the first half of the reading process, and to use the roller I5 during the second half of the reading process, and a complicated mechanism is used for switching between them.

を送るために回転軸にアームを固定して回転機の回転に
よるアームの回転を利用する。In conventional film feeding devices, the rotation of a rotating machine is transmitted to a roller, and the film is fed using friction between the roller and the film. In the above-mentioned feeding, rotation errors of the rotating machine, mechanical errors of the rollers, and slippage between the film and the rollers appear as feeding errors. Reducing this error factor directly leads to improved feed accuracy. Therefore, the structure of the rotating machine ten rollers was changed to only a rotating machine. Since the rotation accuracy of the rotating machine is relatively high, if the rotation of this rotating machine is directly applied to film feeding, highly accurate film feeding can be realized. In order to feed the film directly with a rotating machine, an arm is fixed to a rotating shaft and the rotation of the arm due to the rotation of the rotating machine is utilized.

なる。On the other hand, conventional feeding using friction between rollers and film has the risk of damaging or damaging the film during feeding, thereby degrading or destroying the image information within the film. Therefore, a protective means for protecting the film, such as a guide with something like felt attached to the part where the film passes, is prepared, and the structure is such that the trailing edge of the film is pushed through the guide by an arm while being fed. Naturally, the shape of the guide is an arc.

ム送り装置の各部分の詳細な説明は実施例にて行う。By using the above means, it is possible to improve the feeding accuracy and at the same time ensure the safety of the film. A detailed explanation of each part of the film feeding device of the present invention will be given in Examples.

を可能な限り小さくしてやることにより解決゛出来る。In order to improve the accuracy of film feeding, we will try to minimize as much as possible the rotation errors of the rotating machine, the mechanical errors of the rollers, and the slippage between the film and the rollers, which are factors in the feeding accuracy of conventional devices. This can be resolved by doing this.

ようにしたため、フィルムの安全が保証される。In other words, reducing the error factors as described above from a rotary machine and rollers to only a rotary machine directly leads to improved accuracy. On the other hand, with regard to ensuring the safety of the film, no improvement can be expected from the current level as long as the conventional device uses a structure in which the film is fed by utilizing friction between the film and the roller. Therefore, a structure other than the rotating machine ten-roller structure is desired while meeting the above-mentioned requirement for improved accuracy. In the present invention, a means for protecting the film from scratches, etc., such as a guide with felt attached to the film travel path, is used, and the film travels through the guide, so that the safety of the film is guaranteed.

ィルムはローラ９により、マガジン１０に収納される。Figure 2 is a cross-sectional plan view of the film 17 taken along line XX in Figure 1.
The rear edge of the film is pushed by an arm 7 fixed to the rotating shaft of the rotating machine 6, and the film is sent through a guide 8 that has a means (for example, felting) inside to protect the film and make it move smoothly. . The guide 8 has a shape that follows the trajectory of the rotation of the arm 7, that is, a circular arc shape centered on the rotation axis of the rotating machine 6. In addition, the film 17 is placed on the guide 8.
The means for transporting the material into the container is not shown and is omitted. Film feeding is started when a portion of the film 17 crosses the sensor 11. Reading is performed by a laser beam from a light source 1 being reflected by a mirror 2 and being scanned by a rotating polygon mirror 3 onto a detector 5 through which a film 17 passes. Note that the lens 4 is a lens for focusing the scanning light. Also, the arm 7
rotates so as not to interfere with laser beam scanning by the rotating polygon mirror 3, lens 4, etc., and pushes the film 17 to the end, ensuring smooth film feeding and full-screen reading. The film 17 is fed as described in section 2, and the image information in the film is converted into an electric signal (digital signal) by the laser beam scanning described above and the optical detector 5 which receives the laser beam transmitted through the film. When the trailing edge of the film 17 hits the detector 5, the reading of the film ends, and the film is stored in the magazine 10 by the rollers 9.

The precision of film feeding does not require high precision in the dimensions of the arcuate guide; it is determined only by the rotational precision of the rotary machine, so if the rotary machine is carefully considered, it will be possible to feed the film with higher precision. In addition, if trash is generated by the guide, please
