Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information recording device such as a magnetic tape device used in an image information file device, for example.

(Prior Art) Conventionally, as a method for storing and retrieving document images as they are, there is a method that records reduced images as they are on microfilm. However, recently, as an alternative to this, a two-dimensional scanning device that uses photoelectric conversion technology using laser light and CCD elements is used to decompose document images into pixels and convert them into electrical image signals. 2. Description of the Related Art Image information file devices have been developed that record at high density on magnetic recording media, such as magnetic tape.

In this type of device, index information consisting of the recording position of a document image and an index code representing the image information is also stored on the magnetic tape, and the index code can be inputted as needed. The document image corresponding to the index code is searched and can be retrieved as a hard copy.

In addition, the above magnetic tape is built into a cassette,
This cassette can be freely removed by pressing an eject key except when it is rotating.

FIG. 1 specifically shows the above-mentioned conventional image information file device, in which a two-dimensional scanning device 1 photoelectrically converts image information P to binarize it, and converts it into a binary image.
The image information is stored in the RAM (random access memory) 2, and when one page worth of image information is stored, the control device 3
sequentially files the contents of the RAM 2 from blocks of a predetermined track onto the magnetic tape in the magnetic tape device 4.

At the same time, the index code of the object to be read is input from the keyboard 5, and is stored in the RAM 6. At this time, the track position, block position, etc. of the above-mentioned image information are added to this index code to become index information.

In this way, when a series of image information files have been completed, the control device 3 sequentially reads each index information stored in the RAM 6 and files them on the magnetic tape.

However, in such an apparatus, the index information is recorded on the magnetic tape after a predetermined number of image information is filed on the magnetic tape.

Therefore, depending on the time or when the number of image information to be filed is small, image information is written on the magnetic tape and no index code is recorded.

In this state, when replacing the cassette, the cassette in which only the above-mentioned image information is recorded is removed.
That is, when the tape was later searched, the index information was not recorded, so it became impossible to search for image information.

Therefore, there is a drawback that only image information is recorded and index information may not be recorded on the recording medium.

(Problems to be Solved by the Invention) This invention eliminates the drawback that only image information is recorded and index information is not recorded on the recording medium, and it is possible to ensure that image information and index information are recorded reliably. The recording medium can only be removed when it is recorded on the medium.
An object of the present invention is to provide an information recording device that can prevent recording of only image information.

[Structure of the Invention] (Means for Solving the Problems) The information recording device of the present invention includes a recording device main body that records image information on a recording medium together with an index code assigned to each piece of image information, and The apparatus comprises a control means for controlling the recording medium so that it can be taken out from the main body of the recording apparatus only when all of the image information and index code supplied to the medium have been recorded.

(Function) The present invention is so controlled that the recording medium can be taken out from the main body of the recording apparatus only when all of the image information and index code supplied to the recording medium have been recorded.

(Embodiment) Hereinafter, an outline of an image information file device according to the present invention will be shown, and the same reference numerals will be given to the same parts as in FIG. 1, and the explanation will be omitted.

That is, the magnetic tape device 4 is provided with a locking mechanism 7 for locking a bucket 28 (into which a cassette containing a magnetic tape is inserted), which will be described later.

During information recording, this lock mechanism 7 operates until the recording of the index information stored in the RAM 6 is completed, that is, while the control device 3 is supplying an ejection prohibition signal, the eject key (eject key) for ejecting the cassette is pressed. It was made so that it would not be possible to do so.

FIGS. 3 and 4 are perspective views showing the schematic structure of the main parts of the magnetic tape device 4, which are configured as follows, for example.

That is, the shaft 1 is attached to the bottom plate 11a of the chassis 11.
2 is installed upright, and a drive roller 1 is mounted on this shaft 12.
3 is pivotally supported, and this drive roller 13 and a pinch roller 17, which will be described later,
It is designed to rotate 4.

Further, a shaft 15 is erected on the bottom plate 11a of the chassis 11, and an aluminum plate 16 is rotatably provided on the shaft 15. A pinch roller 17 is rotatably placed on the aluminum plate 16, and the aluminum plate 16 is pulled in the direction of arrow a by a spring 18 and moved in the direction of arrow b by a shaft 20 driven by a solenoid 19. I'm starting to do that.

The solenoid 19 is energized by a removal prohibition signal from the control device 3. Further, a reject drive member 22 is rotatably provided on the shaft 21 of the bottom plate 11a of the chassis 11. This reject drive member 22 rotates in the direction of arrow c in response to the press of the eject key 23. At this time, the pin 16a provided on the aluminum plate 16 engages with the curved portion 22a of the eject drive member 22, so that This rotation is now prevented.

By pressing the scanning section 23a of the eject key 23, the ejecting member 24 is moved in the direction of arrow d by means of a pin 23b on a plate provided in the pushing direction of the scanning section 23a.

As the eject drive member 22 moves, the extrusion portion 22b presses the corresponding protrusion 25a of the eject release member 25. This eject release member 25 is attached to the chassis 11.
It has a U-shape so as to surround the side surface 11b, and the side surface 11 is supported by springs 26, 26.
b.

The eject release member 25 has a lock pin 2.
7 and 27 are provided, and this includes buckets 2 and 27.
The lock levers 29, 29 provided at the bottom of 8 are engaged with each other. The bucket 28 is a cassette (not shown) containing the magnetic tape 14.
is inserted, and is provided above the chassis 11, and the lock pins 20, 20 are inserted into the lock lever 2.
When the bucket bag 28 is removed from the buckets 9 and 29, one side of the bucket bag 28 is lifted to the other side by a drive mechanism which will be described later.

One end of doglegged crank members 30, 30 is rotatably connected to the side of the bucket 28. The crank members 30, 30 are provided with an opening angle control member 31, a long hole 31a of this control member 31 corresponds to a pin 28a provided on the side of the bucket 28, and a long hole 31b corresponds to the chassis 1.
A pin 11c provided on the side plate 11b of 1 corresponds thereto, and controls the opening angle of the crank members 30, 30.

That is, in consideration of manufacturing variations, etc., the pin 31c or the long hole 31 corresponding to the long hole 31a is
The crank member 3 is connected by the pin 28a corresponding to b.
The opening angle is limited to 0.30.

Spring 32, 32 is provided at the other end of the crank members 30, 30, and this spring 3
The crank member 30,
30 is configured to rotate in the direction of arrow e using the central portion 30a as a fulcrum. The above crank member 3
A shaft 33 is suspended between the central portions 30a and 30a of the shafts 0 and 30. An arm 34 is fixed approximately at the center of this shaft 33, and the end of this arm 34 is connected to a shaft 36 that is connected to an air damper 35. The air damper 35 is the spring 3
By absorbing a part of the tensile force of the buckets 2 and 32, the bucket 28 is made to rise more slowly.

Next, the operation in such a configuration will be explained. For example, right now, there is a magnetic tape 14 on a bucket 28.
By inserting the cassette containing the cassette and pushing it downward, the lock lever 29 engages the lock pin 27. This locks the bucket 28 so that it cannot be lifted upwards.

Suppose that the operating portion 23a of the eject key 23 is pressed in this state. Then, the eject member 24 moves and the eject drive member 22 rotates. This rotation causes the extrusion part 22b to move to the projection part 25.
By pressing a, the eject release member 2
5 moves. At this time, the lock pin 27 also moves and is removed from the lock lever 27.

For this reason, the bucket 28 has springs 32 and 3.
By driving the crank members 30, 30 by the tensile force of 2, only one side is lifted upward. At this time, a part of the tensile force of the springs 32, 32 is absorbed by the air damper 35, and the bucket bag 28 is gradually lifted. Then, the rotation of the crank member is stopped by the opening angle control member 28a. At this time, the cassette inserted into the bucket bag 28 can be taken out.

In the above state, the shaft 20 is pulled by the solenoid 19 while the magnetic tape 14 is rotating and until image information and index information are recorded on the magnetic tape 14. As a result, the movement of the aluminum plate 16 drives the magnetic tape 14 so that it does not slip between the pinch roller 17 and the drive roller 23 placed thereon.

Also, due to the movement of the aluminum plate 16, the pin 16a
engages with the curved portion 22a of the eject drive member 22. Therefore, the curved portion 22a of the eject drive member 22 is locked by the pin 16a, the eject drive member 22 and the eject member 24 are not moved, and the operating portion 23a of the eject key 23 cannot be pressed.

In this way, when the rotation of the magnetic tape 14 has stopped and all the image information and index information have been stored, the control device 3 no longer supplies the untaken signal and the solenoid 19 is deenergized.
As a result, the aluminum plate 16 rotates due to the tensile force of the spring 18, and this rotation causes the pinch roller 17 to separate from the drive roller 13 and the pin 16a to separate from the curved portion 22a. This makes it possible to press the eject key 23, and when pressed, it operates in the same manner as described above.

In this way, in the image information file device,
The magnetic tape 14 is ejected only when the index information and image information are reliably stored on the magnetic tape.

In the above embodiments, a case has been described in which the embodiment is implemented in a magnetic tape device that uses a magnetic tape as a recording medium, but it can also be applied to a magnetic disk device that uses a magnetic disk as a recording medium or an optical disk device that uses an optical disk as a recording medium. It can be implemented similarly. In these cases, a locking mechanism is provided to lock the fixing mechanism that fixes the disk.

[Effects of the Invention] As detailed above, according to the present invention, the recording medium can be taken out only when image information and index information are reliably recorded on the recording medium, and recording of only image information is possible. It is possible to provide an information recording device that can prevent this from happening.
