Description

Micro film scanning apparatus {scan apparatus for micro film}

The present invention relates to a microfilm scanning apparatus, and more particularly, to a microfilm scanning apparatus capable of preventing breakage of the microfilm during the scanning operation of the microfilm.

In general, microfilm is a means of information transmission, and has many features such as information miniaturization, accuracy and reliability, speed, and information unification and reconstruction. Such microfilms are roughly classified into two types, a roll type and a sheet type. The rolled microfilm is wound on a reel and put in a cartridge. The plate-shaped one includes a micro jacket, a microfiche, an aperture card, and a film strip. ) And so on.

Here, the microfilm on the roll is usually fitted to a rotating shaft that is rotated by a motor, and the scanning operation is performed while the microfilm is moved to one side by the operation of the motor. That is, the rotating shaft which is rotated by a motor in each side is provided, and the optical reading part for micro films is provided between the said rotating shafts. Then, when the motor of one side is operated by rotating the micro film while the rotating shaft is rotated in a predetermined direction, the desired portion is read by the optical reading unit.

On the other hand, the microfilm may not be easily released from the roll due to the sticking of the microfilm itself or mechanical defects due to long-term storage. However, conventionally, such a defect or the like, and the rotational force by the motor is not controlled, there is a problem that the phenomenon that the microfilm is stretched, torn or broken eventually occurs.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and to provide a micro film scanning apparatus that can prevent the breakage phenomenon of the micro film during the scanning operation of the micro film.

It can prevent tearing or breaking.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art can easily implement the present invention.

1 is a front view showing a micro film scanning device 100 according to the present invention.

First, the body 60 protrudes in the left and right directions, and protrudes upward from the center to which various components are attached.

A motor 11 is provided at one side (left side) of the body 60, and the micro film roll 18 is coupled to the rotating shaft 16 of the motor 11 to form a first driving part 10. In addition, the motor 21 is provided on the other side (right side) of the body 60, and the micro film roll 28 is coupled to the rotation shaft 26 of the motor 21 to form the second driving unit 20. have. Of course, the microfilm 54 extends between the first driving unit 10 and the rolls 18 and 28 mounted on the second driving unit 20.

Subsequently, a horizontal roller 33 is rotated by a motor 31 at a lower side of the first driving unit 10 so that the micro film 54 can pass from the first driving unit 10. The tension roller 34 is provided on the upper portion of the horizontal roller 33 to form the first tension portion 30. Of course, the motor 31 and the horizontal roller 33 is connected by a belt (32). In addition, a guide roller 52 for adjusting the tension of the belt 32 is installed at one side of the belt 32, and the micro film 54 is disposed between the horizontal roller 33 and the first driving part 10. Guide rollers 51 for adjusting the tension are installed.

Subsequently, the lower portion of the micro film 54 passing through the first tension portion 30 is provided with illumination, so that a reading unit (not shown) positioned above the micro film 54 is provided with the micro film ( The lighting unit 70 is provided to allow the 54 to be easily sold.

In addition, a horizontal roller 43 is provided at a lower portion so that the micro film 54 passes from the lighting unit 70, and a tension roller 44 is provided at an upper portion of the horizontal roller 43 to provide a second tension portion ( 40). Of course, a guide roller 53 for adjusting the tension of the microfilm 54 is provided between the second tension portion 40 and the second driving portion 20.

2 is a partial cross-sectional view showing the main part of the microfilm scanning apparatus 100 according to the present invention. Here, since the structures of the first driving unit 10 and the second driving unit 20 are the same, only the first driving unit 10 is shown.

As illustrated, the microfilm scanning apparatus 100 according to the present invention uses the clutch plate 15 using the magnetic material 14 to the motor 11 of the first driving unit 10, thereby causing damage to the microfilm 54. The phenomenon can be prevented. That is, a substantially circular metal plate 13 is coupled to the rotating shaft 12 of the motor 11, and the clutch plate 15 to which the rubber magnetic body 14 is coupled is spaced apart from the metal plate 13 by a predetermined distance. It is. In addition, a rotation shaft 16 is coupled to the clutch plate 15, and the rotation shaft 16 has a micro film roll 18 coupled to one end thereof while being coupled to the bearing 17. Therefore, even if the rotating shaft 12 and the metal plate 13 of the motor 11 is rotated, only the metal plate 13 is idle when the micro film roll 18 is not rotated for mechanical coupling or for any reason, Since the micro film roll 18 is not rotated, the breakage, the breakage, etc. of the micro film 54 wound around the micro film roll 18 can be suppressed.

Referring to the operation of the microfilm scanning device 100 according to the present invention having such a configuration is as follows.

First, when the microfilm 54 is scanned and inspected, the first driving unit 10 does not operate, and only the first driving unit 10 and the first tension unit 30 operate. That is, when the motor 11 of the first driving unit 10 operates, the rotating shaft 12 and the metal plate 13 connected thereto rotate. When the metal plate 13 rotates, the clutch plate 15 coupled with the magnetic body 14 in front of the metal plate 13 rotates, and thus the rotation shaft 16 formed on the clutch plate 17 also rotates. Then, the micro film roll 18 coupled to the rotation shaft 16 also rotates.

In addition, when the motor 31 of the first tension unit 30 operates, the belt 32 connected to the motor 31 also rotates in a predetermined direction, and thus the horizontal roller 33 coupled to the belt 32. ) Rotates in a certain direction. Here, the micro film roll 18 and the horizontal roller 33 both rotate counterclockwise.

In this case, the micro film 54 may not be easily released due to the mechanical defect of the scanning apparatus 100 or the adhesion of the micro film 54 itself. On the other hand, the motor 11 of the first driving unit 10 continues to operate. However, since the metal plate 13 and the clutch plate 15 of the motor 11 are indirectly connected to the magnetic body 14, only the metal plate 13 rotates, and the clutch plate connected to the micro film roll 18. 15 does not rotate, and therefore, the breakage or breaking of the microfilm 54 can be suppressed.

Subsequently, in the case of rewinding the micro film 54, the motor 21 of the second driving unit 20 rotates clockwise, and the motor 21 of the second driving unit 20 also rotates clockwise. The micro film 54 is naturally wound on the micro film roll 28 of the second driving part 20. Here, the motor 31 of the first tension unit 30 is not operated.

As described above, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto, and various modified embodiments may be possible without departing from the scope and spirit of the present invention.

Therefore, according to the microfilm scanning apparatus according to the present invention, instead of directly connecting the rotary shaft and the motor to which the microfilm roll is coupled in the first driving unit and the second driving unit, the coupling between the clutch plate and the metal plate provided with a magnetic body is provided. When the rotational force of the motor is indirectly transmitted to the rotational shaft, when the microfilm does not move due to mechanical defects or the adhesion of the microfilm itself, the microfilm is stretched or torn by not applying excessive rotational force to the microfilm. There is an effect that can prevent the falling or breaking.
