Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control system for recording and reproducing apparatuses such as VTRs and tape recorders.

[Summary of the invention]

The present invention provides a sheet-shaped portion provided with a memory or a memory and a microprocessor, a means for receiving power supply, and a means for communicating between the memory or the memory and the microprocessor and the outside, into a cassette containing a recording medium. means for attaching and supplying power to the sheet-like member;
By providing the recording/reproducing device with a means for communicating with the sheet-like member, the recorded contents of the recording medium can be stored in the memory, the stored contents can be read out as needed, and the contents can be displayed, timer recording, etc. can be controlled. It was designed to do this.

[Conventional technology]

Tape cassettes used in recording and reproducing devices such as VTRs and tape recorders are usually equipped with an index card, and this card shows recorded contents, recording position, recording date and time, recording mode, tape type, and other necessary information. I try to fill it out by hand.

In addition, techniques for controlling the device by gluing a sheet marked with control data onto a cassette or by installing a circuit inside the cassette are disclosed in Japanese Utility Model Application Publication No. 58-7286 and Japanese Utility Model Application Publication No. 57-189186, etc. has been disclosed.

[Problem that the invention seeks to solve]

Conventional index cards are very cumbersome because they are filled in by hand, and even if such cards are available, you have to perform fast forwarding, rewinding, etc. to find the beginning of the tape during playback. There must be. Furthermore, conventional devices that perform timer recording are provided with a dedicated timer storage circuit. Furthermore, when playing back a cassette using a conventional device, it is not possible to perform program playback in accordance with the recorded contents of the cassette.

[Means for solving problems]

In the present invention, a sheet-like part is provided with a memory or a means for receiving power supply from the memory or the memory and the microprocessor and a means for communicating with the outside and is attached to a cassette. The recording and reproducing apparatus is provided with means for supplying power to the sheet-like member and means for communicating with the sheet-like member, in addition to being provided in a cassette containing the medium.

[Effect]

Items written on conventional index cards can be stored in memory. Based on this stored content, display of recorded content, cueing, program playback, timer recording, etc. can be controlled.

〔Example〕

In FIG. 2, for example, two control sheets 2 are adhered to a mount 1. As shown in FIG. 3, the sheet 2 includes an IC circuit 4 including a memory and a microprocessor on a flexible printed circuit board 3;
A conductive path 7.8.9 is formed which is connected to the conductive path 7.8.9 via a wire 5.6, and has a structure in which the entirety thereof is coated with resin 10. This sheet 2 has adhesive 1 on mount 1.
1 and is removably bonded. This sheet 2 can be formed to have a total thickness t of about 0.5 to 11 cm. Further, the memory used has a capacity of 2 bytes, for example. Incidentally, FIG. 2 shows a state in which one sheet 2 is partially peeled off from the mount l. Further, it may be possible to write notes on the sheet 2, or to print characters, figures, etc. on the sheet 2.

FIG. 4 shows the case where the sheet 1 is adhered to the video cassette 12. A rectangular shallow recess 13 is provided on the top surface of the video power set 1-12.
Sheet 2 is adhered using 3. This sheet 2
The cassette 12 to which the cassette 12 is attached is mounted on a cassette mounting section of a VTR, and communication between the VTR and the sheet 2 is performed.

FIG. 1 shows an embodiment of the circuit in the sheet 2 and the recording/reproducing device 14. As shown in FIG.

The seat 2 is provided with a microprocessor 15, a memory 16, a coil 17 to which power is supplied, a communication coil 18, a rectifying diode 19, and the like. The recording/reproducing device 14 also includes a coil 20 for supplying power, and an AC power supply 2.
1. A communication coil 22, an interface input 23 are provided, and various circuits such as a tape counter 24, a timer 25, a keyboard 26, a display device 27, etc. are provided.

The coils 20 and 22 are installed in the cassette mounting section, and when the cassette 12 to which the sheet 2 is attached is mounted,
Coils 17 and 20 are close to each other, and coils 18 and 2 are close to each other.
2 are arranged close to each other.

According to the above configuration, the AC voltage of the AC type ALX 21 is supplied to the sheet 2 via the coil 20.17, rectified by the diode 19, and applied to the microprocessor 15 and memory 16. Further, the microprocessor 15, the memory 16 and the various circuits 24 to 27 are connected to the coils 18 and 22.
Data can be mutually received and transmitted via the interface 23 and the interface 23.

With this, for example, the above-mentioned items that were conventionally written on an index card can be entered into the memory 16 using the keyboard 26.
The information can be stored in the memory, and can be displayed on the display device 27 if necessary. Further, by using the stored contents of the memory 16, it is possible to easily perform program playback during playback, and it is also possible to easily perform timer recording, cueing of the tape, etc.

In addition, the microprocessor 15 may be provided in the recording/reproducing device 14 in FIG. Further, as a means for power supply and communication, a method using capacitance may be used. Further, the present invention can be applied to recording and reproducing apparatuses using various cassettes such as cassettes of VTRs, tape recorders, etc., cassettes of floppy disks, and the like.

〔Effect of the invention〕

Various items regarding the recorded contents of the cassette can be stored in the memory. Based on this stored data, display,
Program playback, timer recording, cueing, etc. can be performed extremely easily.

It can be implemented without changing the model or standard of the VTR or tape recorder, or the tape format, and can also be applied to conventional cassettes.

Additionally, data organization can be unified. sheet 2
If mass-produced, it can be obtained relatively cheaply, and the cost will not particularly increase.
