DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium used in a case where a tape-shaped recording medium such as a video cassette tape is accommodated in a case. The present invention relates to a cassette label that can be recorded and a video cassette tape to which the cassette label is attached.

[0002]

2. Description of the Related Art There is a demand for recording and storing video data which is photographed by an image pickup device such as a television camera and recorded on a video tape in such a manner that information such as its contents can be easily confirmed. . Especially,
In the case of a television broadcast station used for news gathering, a necessary cut is quickly selected from a large number of cuts (consecutively shot images or video data) shot by a video camcorder or the like. Need to be edited.

Until now, usually, such information of recorded video data is recorded in a separate memo at the time of shooting, and at the time of reproduction or editing, desired video data is selected at a high speed while viewing the memo. Such a method is used. In a system for automatically handling a large number of video cassettes such as a cassette library, video cassette tapes are managed using a cassette label on which a barcode is printed.

In recent years, in a 1/4 inch digital video cassette tape or the like, a semiconductor memory device such as a flash memory is incorporated in a cassette for accommodating a video tape so that information such as recording time, recorded contents, and title can be recorded. Some are. The recording and reproduction of data with respect to the semiconductor memory device incorporated in such a video cassette tape are provided, for example, near the erroneous erasure prevention tab on the back of the cassette case. This is performed by a contact method via an electrode composed of:

[0005] However, such a conventional method has limitations and inconveniences in various forms of use.
For example, in a method of taking a memo on paper, the paper may be lost, or processing based on the memo cannot be automated. In a method of printing a barcode on a label, the amount of information that can be recorded is limited and not sufficient. In addition, in the method using a semiconductor memory, there is a problem that the electrodes must be brought into appropriate contact with each other and the positioning thereof must be performed with high accuracy, and a problem of poor contact due to adhesion of dust or the like. In addition, for an enormous amount of video cassette tapes, such as hundreds of thousands of television broadcast stations where video data has already been recorded, the information of the recorded video data is digitized and held. There is also a problem that these methods are not appropriate for doing so.

Accordingly, the present inventors have already disclosed in Japanese Patent Application No. Hei.
A cassette label that accommodates an integrated circuit such as a semiconductor memory and that can transfer data to the outside by a non-contact method as proposed in Japanese Patent Application No. 300449 is proposed. If the additional information of the video data recorded by the cassette label is managed, the various problems as described above can be solved. Further, the present invention can be easily applied to a video cassette tape on which video data is already recorded.

The structure of the cassette label will be described with reference to FIG. The cassette label is composed of a label body 11 and a double-sided adhesive 17, and further includes a label body 1
1 is a coated paper 12, a reinforcing material 14, as shown in FIG.
In this configuration, a polyimide substrate 16 is adhered with pressure-sensitive adhesives 13 and 15 to be integrally formed. Coated paper 12
The surface, that is, the surface opposite to the surface facing the reinforcing member 14 can write information such as the title, recording date and time, and recording location of video data recorded on a video tape, for example.

The reinforcing member 14 has a certain strength so that even if a force such as bending is applied to the cassette label 1, each member of the cassette label 1 or the IC 20 or the antenna 30 is not broken or cut. It is a member of. An opening 141 is formed in the reinforcing member 14 at a position overlapping the IC 20 when the reinforcing member 14 is attached to the polyimide substrate 16 so as to absorb the thickness of the IC 20.
In addition, when the coated paper 12, the reinforcing material 14, and the polyimide substrate 16 are bonded together,
The space formed around 20 is filled with an IC protection material.

The polyimide substrate 16 is a substrate on which the IC 20 and the antenna 30 are mounted. In the cassette label 1 of the present embodiment, the IC 20 is mounted on one end of the polyimide substrate 16, and the antenna 30 is wired at the center of the polyimide substrate 16. The double-sided adhesive 17 is a member for attaching the label main body 11 to a video cassette tape, and one surface thereof is a polyimide substrate 16
And a release paper 18 is adhered to the other surface. Therefore, when using the cassette label 1, the user peels off the release paper 18 and attaches the cassette label 1 to a video cassette tape.

[0010]

However, such a cassette label has some inconveniences and disadvantages, and an improvement is desired. For example, the cassette label as described above with reference to FIG. 6 has a problem that the structure is relatively complicated, the manufacturing process is complicated, and the cost is high. Specifically, for example, the label body 11
In addition to the polyimide substrate 16 on which the IC 20 and the antenna 30 are mounted, a plurality of members such as a coated paper 12 and a reinforcing member 14 are used, and there is a demand for simplification. In addition, the label body 1 having such a configuration
1 has insufficient strength, and there is also a problem that the IC 20 must be filled with an IC protective material around the IC 20 so that a load such as writing pressure is not directly applied to the IC 20 when writing characters or the like.

In addition, in order to protect the IC 20 from pen pressure and the like, a product logo, a manufacturer's logo, or the like is printed on the coated paper 12 at a position where the IC 20 is accommodated, and characters are not written on that portion. However, such a configuration has a problem in that the IC 20 must be disposed at the end of the cassette label, and the degree of freedom in design is reduced. In addition, since the surface member on which characters and figures are written is coated paper 12, writing characters with a ballpoint pen, magic, or the like is substantially difficult to rewrite, and the cassette label 1 is difficult to use repeatedly. is there.

Accordingly, an object of the present invention is to provide a cassette label which can accommodate an IC and perform non-contact communication to manage additional information of video data. It is an object of the present invention to provide a cassette label which can be manufactured with a high degree of freedom, increases design flexibility, and can be appropriately used repeatedly. Another object of the present invention is to appropriately manage additional information of video data recorded by a cassette label of an IC accommodating on a back, and particularly to appropriately use a cassette label repeatedly. Such a video cassette tape is provided.

[0013]

In order to solve the above-mentioned problems, a cassette label is constituted by using a plastic member capable of ensuring strength. In other words, this ensures the strength of the entire cassette label, and at the same time, covers and protects the IC and antenna, and further forms the surface of the cassette label with a surface roughness capable of writing characters and the like.
With this one member, conventional coated paper and reinforcing material and I
In order to realize the function of the C-protecting agent, at the same time, secure sufficient strength to increase the degree of freedom of design, and to provide a character entry surface on which characters and figures can be substantially completely erased. did.

Therefore, the cassette label of the present invention is:

The information, such as the title of the video data recorded at the time, the recording date and time, and the recording location, can be described. As shown in the figure, the IC 20 is disposed at the longitudinal end of the cassette label 1, and the antenna 30 is disposed at the center of the cassette label 1, and they are connected by a part of the antenna 30. In the cassette label 1 shown in FIG. 1, the length a in the longitudinal direction is about 140 [mm], the width b is 18 [mm], and the label body 11
Is 0.6 [mm].

FIG. 2 is a view showing a specific structure of the cassette label 1. As shown in FIG. FIG. 3 is an enlarged cross-sectional view of a portion X shown in FIG. As described above, the label base 10 has a configuration in which the double-sided adhesive 17 is applied to the label main body 11 and further covered with the release paper 18, and the label main body 11 is made of a plastic material 1 as shown in FIG.

rene) formed of resin.

A thin recess 191 is provided in the plastic material 19 at a position corresponding to the position of the IC 20 mounted on the polyimide substrate 16 when the plastic material 19 is adhered to the polyimide substrate 16. Can be accommodated by absorbing the thickness. In addition, as described above, since the surface 111 of the plastic material 19 has a surface roughness of Rmax 20 to 60 μm, it is possible to write characters such as a pencil, a ballpoint pen, and a character using a water-based / oil-based magic in the same manner as high-quality paper. It has become. In addition, characters written with a ball-point pen or magic can be wiped off with alcohol or the like, and characters can be repeatedly written on the writing surface 111.

The polyimide substrate 16 is a substrate on which the IC 20 and the antenna 30 are mounted. As described above, in the cassette label 1 of the present embodiment, I
C20 is mounted on one end of the polyimide substrate 16, and the antenna 30 is wired at the center of the polyimide substrate 16.

Next, the IC 20 and the antenna 30 will be described. The IC 20 is an integrated circuit having a memory unit capable of storing and holding and a signal processing unit. In the cassette label 1 of the present embodiment, the IC 20 has a memory with a storage capacity of 2 Kbytes. The signal processing unit included in the IC 20 is a processor unit that operates with a clock of 13 MHz, and performs processes such as reading / writing data from / to a memory and transferring data to / from an external read / write module via the antenna 30. . The antenna 30 is an antenna for supplying power and transferring signals without a contact between the cassette label 1 and the external read / write module.

Next, the usage and application of the cassette label 1 will be described. FIG. 4 shows a state in which such a cassette label 1 is attached to a video cassette tape 2.

Affixed to 4. At this time, the direction of the cassette label 1 may be arbitrary. Since the antenna 30 of the cassette label 1 is provided near the center of the cassette label 1, the antenna 30 comes near the center of the concave portion 54 of the video cassette tape 2 regardless of the direction in which the cassette label 1 is attached. Thus, the external read / write module may perform communication by arranging an external antenna near the position. An arbitrary figure such as a character or a picture is written on the surface of the cassette label 1 with an arbitrary writing tool, and is used for identifying the video cassette tape 2 or the like. The characters written on the surface of the cassette label 1 are written before the cassette label 1 is attached to the video cassette tape,
It may be printed in advance.

FIG. 5 shows a usage form of the video cassette tape 3 to which the cassette label shown in FIG. 4 is attached. FIG.
FIG. 3 is a diagram showing a state in which the video cassette tape 3 with the cassette label mounted is mounted on a video tape recorder (VTR) device, and data is transferred to the IC 20 in the cassette label 1. As shown in FIG.
When the video cassette tape 3 to which the cassette label is attached is attached to the VTR device, the lid 55 on the surface is opened, and the video tape (not shown) housed in the video cassette tape 3 is pulled out, and the video data is read. It comes into contact with the head of the recording / reproducing device.

On the other hand, near the center of the back surface of the video cassette tape 3, an antenna 9 output from a label read / write module 91 provided in the main body of the VTR device is provided.
0 is placed. Then, the read / write module 9
Reference numeral 1 denotes the I of the cassette label 1 via the antenna 90.
The power supply to C20 and the control are performed. That is, the signal processing unit in the IC 20 reads data from the memory and transfers the data to the read / write module 91 via the antenna 30 and the antenna 90, or transfers the data from the read / write module 91 to the IC 20. Then, the signal processing unit in the IC 20 performs an operation of recording the data in the memory. The read / write module 91 is further connected to a signal processing unit (CPU) on the VTR device side, and is controlled from the VTR device main body side.

By such an operation, data such as a recording position, a recording time, a recording location, and a recording time for each cut of each video data recorded on the video tape, a title indicating the recorded content, and the like are stored in the IC 20. Information, index picture obtained from the cut, or
For example, information such as a good shot mark input by the photographer at the time of photographing is recorded. In addition, the recording time, recording time, and recording time of the entire video data recorded on the video tape

As described above, in the cassette label 1 of the present embodiment, a normal cassette label is used in which some graphics are described and attached to the video cassette tape 2 to identify and grasp the contents of the video cassette tape. Can be used in exactly the same way. If the cassette label 1 is used by attaching it to the video cassette tape 2, various data can be recorded on the IC 20 provided therein. That is, the recording conditions and the information related to the recorded contents which have been written down as a memo can be recorded on the cassette label 1.

In the cassette label 1 of this embodiment, since the plastic member 19 is used as the main member of the label base 10, sufficient strength can be ensured, and when characters are written on the cassette label 1, It is possible to protect the IC 20 from external pressure such as writing pressure. Therefore, it is not necessary to use an IC protection material as conventionally used. Further, the plastic material 19 can be formed with the thickness of the conventional coated paper 12, the reinforcing material 14, and the adhesive layer between them, so that the plastic material 19 can be made thicker than the conventional reinforcing material 14, which is sufficient. Strength can be secured.

Further, since such a conventional structure of the coated paper 12, the reinforcing material 14, and the IC protective material can be replaced with the plastic material 19, the number of components can be reduced and the manufacturing process can be simplified. And cost can be reduced. Further, since the strength of the cassette label 1 can be sufficiently ensured by the plastic material 19 as described above, it is not necessary to dispose the IC 20 at the end of the cassette label 1, and the degree of freedom in designing the cassette label 1 is increased.

The entry surface 111 for characters and figures is also
Since it is composed of a part of the plastic material 19, even if a character is described here with a ball-point pen or magic, it can be erased later by wiping it with alcohol or the like. In other words, data can be rewritten many times to the IC 20 inside the cassette label 1 without any practical limit, for example, tens of thousands of times. It is possible to rewrite even once, and the cassette label 1 can be used repeatedly and appropriately.

In addition, the cassette label 1 of the present embodiment
Can be attached to a video cassette tape on which video data is already recorded. Also, this I
