Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a non-contact method suitable for application to a system using a recording medium or storing a recording medium, such as a camera-integrated VTR, a portable or stationary VTR, a cassette autochanger, a recording medium storage system, and the like. The present invention relates to a type IC memory card system.
[0002]
[Prior art]
Broadcasting stations and the like often record outdoors using a camera-integrated VTR. The recorded material is usually edited as a broadcast material. Editing should be used while the editor plays the video tape cassette containing the material recorded on the camera-integrated VTR on the video tape recorder for editing and watches the playback video on the television monitor. This is done by instructing the position to an editing machine or the like. The position to be used is usually performed by time code data. When a video tape cassette is played back, the video tape recorder plays back not only material but also time code data. The time code data is supplied to an editing machine that also controls the video tape recorder.
[0003]
Therefore, when the editor presses the in-point designation key and the out-point designation key when the first and last images of the range to be used are projected, the time code data at that point is stored by the editing machine. Is done. When such an editing operation is repeatedly performed, all editing points on the video tape cassette are stored in the editing machine. Accordingly, the editing machine can cause the VTR to reproduce only the range to be used while sequentially reading the time code data of the stored editing points.
[0004]
However, finding edit points is not easy. This is because a single material is not always recorded continuously in one video tape cassette. Moreover, since the person who records the material is different from the person who edits it, it is difficult to determine the intended position of the person who recorded the material. For example, when recording in a tourist spot, it is almost impossible to keep shooting only famous temples at the same angle, unless there is a special purpose. Usually, you will take pictures of famous temples, famous waterfalls, towns, and so on, moving in sequence. Then, the recording button and the recording release button of the camera-integrated VTR are pressed at least once for each shooting location. In the editing operation, it is necessary to search the above-mentioned positions, that is, the recording positions of temples, waterfalls, and towns on the magnetic tape of the video tape cassette.
[0005]
In this way, editing video tape cassettes with material is never efficient. Therefore, when an IC memory is mounted on a video tape cassette, for example, when recording with a camera-integrated VTR, information other than the recorded material itself is stored in the IC memory of the video tape cassette for editing. Proposed to be used. That is, it is proposed that an IC memory device is mounted on a recording medium, and information other than the captured video signal and audio signal, for example, additional information such as date and title, is stored in the IC memory and used later according to the purpose. It was done. “Registered” here means that the IC memory is incorporated in the video tape cassette as a component of the video tape cassette so that it cannot be removed unless the video tape cassette is disassembled. Means.
[0006]
A reader / writer device is used to write data to an IC memory device mounted on a video tape cassette and read data stored in the IC memory device. The IC memory device has metal terminals for data input / output and control. The reader / writer device also has metal terminals for data input / output and control. When writing data to the IC memory device or reading data stored in the IC card device, the metal terminal of the IC memory device and the metal terminal of the reader / writer device are brought into mechanical contact.
[0007]
It will be easy to understand by taking the camera-integrated VTR as an example. An IC memory device is mounted on the video tape cassette, and a reader / writer device is mounted on the camera-integrated VTR. When the video tape cassette is loaded into the camera-integrated VTR, the tape transport unit pulls out the magnetic tape from the video tape cassette and winds it around the rotating drum. A metal terminal of the IC memory device is brought into contact with the terminal. Thereafter, data reading and data writing are performed by the microcomputer of the camera-integrated VTR.
[0008]
Therefore, if the reader / writer device is installed in the editing machine, the editing efficiency is surely improved. In other words, an editing machine reads data from an IC memory device of a video tape cassette in which material is recorded by a camera-integrated VTR, and uses the data for editing. In the above example, the time code data at the start and end of shooting of temples, waterfalls, and towns are stored in the IC memory device by key input or the like. In this way, the editing machine can read the time code data from the IC memory device and set the position of the video tape cassette on the magnetic tape as the recording position of the read time code data. Therefore, the person who edits does not need to perform a troublesome task, for example, searching for a recording position of a temple, a waterfall, or a town while looking at the reproduced image.
[0009]
[Problems to be solved by the invention]
By the way, there is a difference between the life of the IC memory and the life of the video tape cassette. Therefore, when the IC memory device is mounted on or attached to the video tape cassette, if the IC memory is broken, the video tape cassette is wasted and the video tape cassette cannot be used. If this happens, the IC memory is wasted.
[0010]
Further, since the above system is a contact type system in which the metal terminal of the IC memory device and the metal terminal of the reader / writer device are in contact, the metal terminal of the IC memory device and the metal terminal of the reader / writer device A drive system is required to make the contact. Further, in the case of a contact type system, it is easy to cause a contact failure or the like, and in that case, there is a high possibility of causing data destruction or equipment damage.
[0011]
The present invention has been made in consideration of such points, and proposes a non-contact type IC memory card system that can effectively use resources, minimizes the configuration, and prevents data destruction and damage to equipment. It is what.
[0012]

The modulation circuit 54 performs ASK (Amplitude Shift Keying) modulation using the carrier wave signal from the 1/4 frequency divider circuit 51, an adder circuit 53, and a transmitting antenna 58t.
[0023]
The receiving system includes a receiving antenna 58r, a variable capacitor C, an amplifier circuit 59, a bandpass filter 60, and an equalizer 61.
[0024]
[Operation when writing data]
For example, various data such as key inputs on the operation panel of the recording / reproducing apparatus 41 shown in FIG. 1 and time code data from the main microcomputer of the recording / reproducing apparatus 41 are transmitted via the input terminal 47 and the interface circuit 48. It is supplied to the computer 49.
[0025]
The microcomputer 49 supplies the data to the modulation circuit 54. Further, the microcomputer 49 supplies a clock signal to the ¼ frequency dividing circuit 51. The data supplied to the modulation circuit 54 is modulated by the carrier wave signal from the 1/4 frequency dividing circuit 51. This modulation signal is supplied to the adding circuit 53. The adder circuit 53 is supplied with a carrier wave signal from the 1/4 frequency divider circuit 51. In the adder circuit 53, the carrier wave signal from the 1/4 frequency divider circuit 51 and the modulation signal from the modulation circuit 54 are added. The addition signal from the addition circuit 53 is amplified for transmission in the amplification circuit 55 and then transmitted by the transmission antenna 58t.

[0030]
The reader / writer device 42 of the non-contact type IC memory card system described above can be used by being attached to a VTR portion of a camera-integrated VTR, a cassette auto changer VTR, a stationary type or a configuration type VTR. As described above, the easy to imagine is that after recording the material with the camera-integrated VTR, the video tape cassette containing the material is loaded into the editing VTR, etc. For example. In this case, the content stored in the non-contact type IC memory card mounted on the video tape cassette is read by a reader / writer device mounted on the editing VTR, and editing is performed based on the information. Therefore, editing efficiency can be greatly improved. The reason for this has already been explained.
[0031]
Further, if the reader / writer device is mounted on the cassette hand portion of the cassette autochanger, it is not necessary to perform position detection, barcode reading, or the like as in the prior art.
Further, it can be used as a portable reader / writer device used in a recording medium storage system. For example, broadcast stations and the like store a large amount of recorded video tapes, cassettes, and the like. Therefore, if a portable reader / writer device is used, the video tape cassette that is being searched for can be found immediately. In this case, however, a character generator, an LCD display, and the like are further installed so that the microcomputer 49 shown in FIG. 3 converts the received data into a code and supplies the code to the character generator. Don't be.
[0032]
For example, assuming that the recording date of the video tape cassette is stored in the IC memory card 11 attached to each video tape cassette, the portable reader / writer device is sequentially connected to the video tape cassette.・ When you bring it closer to the tape cassette, the display section will sequentially display information on letters and numbers indicating the date of recording. Search for a video tape cassette recorded on a specific date. It ’s easy.
[0033]
As described above, in this embodiment, since the non-contact type IC memory card 11 can be detachably attached to the memory card mounting portion 21 of the cassette body 2, the cassette body 2 becomes unusable. Even in such a case, the IC memory card 11 can be reused, and even when the IC memory card 11 becomes unusable, the cassette body 2 can be reused, resulting in effective use of resources.
In addition, since writing and reading of data in a non-contact state are realized, the configuration can be minimized, and data destruction and device damage can be prevented.
Also, a non-contact type IC memory card 11 to be mounted on a recording medium, and a search device for the recording medium reproducing device, recording device, recording / reproducing device, and storage device (in the above example, a cassette hand unit or a portable reader / writer) Since the reader / writer device 42 mounted on the writer device constitutes a non-contact type IC memory card system, there is an advantage that various forms can be easily realized according to the purpose.
[0034]
【The invention's effect】
According to the present invention described above, since the IC memory card is not contacted with the reader / writer device, the data is written to and read from the IC memory card. There is an effect that destruction and damage to equipment can be prevented.
Further, since the IC card memory can be freely attached to and detached from the recording medium, there is an effect that resources can be used effectively.
