Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film drive device, and more particularly to a device for selectively driving a film in order to quickly recall desired information recorded on a desired film to a predetermined position.

For example, in conventional multi-item information input devices, the long operation required to select and position the input item corresponding to the information to be inputted on the input section;
In order to eliminate various drawbacks such as inaccurate positioning, the present inventor first created a plurality of tapes each storing a large number of items to be input, and a plurality of tapes in which the tape is wound from one end of each tape. tape holding means;
and a tape concentrated holding means in which the tapes are wound together from the other end of the tape wound around the tape holding means, and the tape holding means are arranged in an annular shape around the tape concentrated holding means, and the entire tape holding means Alternatively, a tape selection drive device was developed which includes a drive means for selectively driving the tape central holding means (see Japanese Patent Laid-Open No. 59-27371). This tape selection drive operates quickly and accurately, and has the advantage of being able to store and process a large amount of information.

The present invention is an improvement on the previous tape selection drive device by the inventor described above, and includes a roller unit consisting of a pair of rollers (first and second rollers) and a film wound around these rollers. of,
N sets are arranged in a rectangular annular shape, and by selectively driving the first roller or second roller of each roller unit in one direction or the opposite direction, the film of each roller unit can be moved in one direction or the opposite direction. , relates to a film drive device configured to be able to rotate an N-gonal annular body by a predetermined amount. This device has the advantage of being able to process information on the tape sections on the two first and second rollers, as well as the tape section between the rollers, and since the rollers are all on the same circumference, The mechanism for selectively driving the first roller and the second roller to rotate has an extremely simple structure consisting of two ring gears and an associated motor. Furthermore, since the roller unit is made removable, the tape can be easily replaced.

To explain with reference to the drawings, the principle of the present invention is shown in FIG. In the film driving device of the present invention, N pairs (6 pairs in the figure) of rollers 2 and 3 are arranged in an N-prismatic column shape along the circumference of one circle 1, and a corresponding one is arranged around the first roller 2 of each pair. The tape 4 is wound from one end thereof, and the tape is wound from the other end around the second roller 3 of the same pair. Drive mechanism 1 to be described later
00 (FIG. 5), the film 4 is moved by rotating the first roller 2 counterclockwise (FIG. 1) or the second roller 3 clockwise by a predetermined amount,
Information processing can be performed on the required film portions. For example, as shown in FIG. 2, if guide plates 5 and 6 are provided corresponding to each pair of first and second rollers 2 and 3, information on the tape portions on these guide plates can be processed. , also the third,
In the case of a cassette as shown in FIG. 4, information on the tape portion between rollers 2 and 3 can be processed.

3 and 4 show an example of a cassette 10 in which each pair of first roller, second roller, and film are assembled as a removable roller unit. This cassette 10 includes a pair of first roller 2 and second roller 3.
A cassette 11 rotatably accommodates the cassette 10, aligned elongated openings 12 and 13 provided in the casing to expose the upper and lower surfaces of the film portion 4a between these rollers 2 and 3, and means for removably attaching the
For example, it consists of a key 14 provided in the casing 11. Gears 15 and 16 are fixed to the end shafts 2a and 3a of the first and second rollers 2 and 3 that protrude from one end wall 11a of the casing 11 to the outside, respectively, and these gears are connected to the roller drive mechanism 100. do. The roller drive mechanism 100 includes rollers 2,
The first link gear 17 includes a first link gear 17 and a second link gear 18 located coaxially with the circle 1 on which the roller 3 is arranged and adjacent to each other.
5, and the second link gear 18 externally meshes with the gear 16 of the second roller 3. These link gears 17 and 18 are connected to suitable transmission means (for example, gear 1
9, clutch 20, etc.) to step motor 21
By selectively driving the roller at , the corresponding roller can be rotated. In addition, in the figure,
A drive device for the first link gear 17 is not shown. For example, if the step motor 21 rotates the second link gear 18 clockwise (FIG. 6) by a predetermined amount, the film 4 is wound around the second roller 3, and the first link gear 17 is similarly rotated clockwise. Then, the film 4 is wound around the first roller 2. Drive mechanism 1
00 is suitably supported on the frame of the device.

The cassette 10 is removably assembled into an N-gon shaped body according to the principle shown in FIG. For example, FIG. 7 shows an example in which it is assembled into a hexagonal shape and applied as a microfilm reader. Drive mechanism 100 is not shown. The six cassettes 10 each have a key 14.
The light source 32 is removably attached to the frame 31 of the apparatus via the hollow body to form a hexagonal column hollow body, and the light source 32 is disposed at the center of the hollow body. In this relationship, the first
and the exposed film portion 4a between the second rollers 2 and 3
are located equidistant from the light source 32. The film 4 is a micro film, and a leader 3 is placed on the opposite side (that is, outside) of the light source 32, sandwiching the film portion 4a.
3 and moving the film using the drive mechanism 100, the microfilm can be searched. There are six readers 33 corresponding to each cassette 10.
If you set up 6 films, you can search for 6 films at the same time. If there is only one leader, move the leader or rotate the entire assembly.
The leader 33 may be made to face the desired film portion 4a.

Due to the above structure, the film drive device of the present invention has various advantages such as a simple drive structure, easy film replacement, and the ability to process information on N films at the same time. .

Although the illustrated embodiment has been described with reference to a hexagonal cassette, the cassette is not limited to a hexagonal shape and can be assembled into any polygonal shape.

The present invention applies not only to microreaders, but also to various input devices for computers, telephone exchange systems, magnetic recording devices, library systems, atlases, etc.
It can be used for various applications depending on the type of film.
