Description

The present invention relates to a control method for a recording / reproducing apparatus such as a VTR or a tape recorder.

[Conventional technology]

A tape cassette used in a recording / reproducing apparatus such as a VTR or a tape recorder is usually provided with an index card, and this card stores the recorded contents, recording position, recording date, recording mode, tape type, and other necessary items. I try to write it by hand.

Further, a technique for adhering a sheet on which control data is marked to a cassette or providing a circuit in the cassette to control the apparatus is disclosed in Japanese Utility Model Publication No. 58-7286 and Japanese Utility Model Publication No. 57728.
-189186 gazette etc. are disclosed.

[Problems to be solved by the invention]

Conventional index cards are very troublesome because they are filled in by hand.Also, even if such a card is prepared, when playing, fast forward, rewind, etc. are performed to find the beginning of the tape. There must be. Further, the conventional apparatus for performing timer recording is provided with a dedicated timer storage circuit. Furthermore, when reproducing a cassette with a conventional device, it is impossible to reproduce a program according to the recorded contents of the cassette.

[Means for solving problems]

According to the present invention, a memory that accommodates a recording medium and is electrically writable and erasable, means for receiving a power supply for this memory from a recording / reproducing device, and communication between this recording / reproducing device and the memory are provided. A recording / reproducing apparatus adapted to perform recording and reproduction on the recording medium by mounting a cassette having a first communication means for
It has means for supplying power to the memory, second communication means for communicating with the memory, and timer means for timer recording, and is stored in the memory when the cassette is mounted. It is characterized in that the timer information corresponding to the timer information is recorded by reading the timer information through the first and second communication means.

[Action]

The items entered on the conventional index card can be stored in an electrically erasable memory. Based on the stored contents, display of recorded contents, cueing, program reproduction, timer recording, etc. can be controlled.

〔Example〕

In FIG. 2, for example, two control sheets 2 are attached to a mount 1. As shown in FIG. 3, the sheet 2 includes an IC circuit 4 including a memory and a microprocessor, a conductive path 7 connected to the IC circuit 4 via wires 5 and 6, on a flexible printed circuit board 3. 8 and 9 are formed, and all of them have a structure coated with the resin 10. The sheet 2 is releasably adhered to the mount 1 via an adhesive 11. The sheet 2 can be formed so that the total thickness t is about 0.5 to 1 mm. As the memory, for example, an electrically erasable memory having a capacity of 2 Kbytes is used. Note that FIG. 2 shows a state in which a part of one sheet 2 is peeled off from the mount 1. See sheet 2
It may be possible to write a memo on, or to print characters, figures, and the like.

FIG. 4 shows a case where the sheet 1 is bonded to the video cassette 12. Since the rectangular shallow recess 13 is provided on the upper surface of the video cassette 12, the sheet 2 is bonded by using this recess 13. The cassette 12 to which the sheet 2 is attached is attached to the cassette attachment portion of the VTR,
And sheet 2 are communicated with each other.

FIG. 1 shows an embodiment of a circuit in the sheet 2 and the recording / reproducing apparatus 14.

The sheet 2 is provided with a microprocessor 15, an electrically erasable memory 16 to which an address signal, a data signal and a control signal such as an erase pulse or a write pulse are connected from the microprocessor 15, and the memory and the microprocessor. Power supply coil 17, trading coil
18. A rectifying diode and a smoothing capacitor (not shown) are provided. Further, the recording / reproducing device 14 is provided with a coil 20 for supplying power, an AC power source 21, a communication coil 22, an interface 23, and a tape counter.
24, a timer 25, a keyboard 26, a display device 27, and other circuits are provided. The coils 20 and 22 are provided in the cassette mounting portion, and when the cassette 12 to which the sheet 2 is adhered is mounted, the coils 17 and 20 are close to each other to form a power transformer, and the coils 18 and 22 are close to each other. To form a binding transformer.

According to the above configuration, the AC voltage of the AC power supply 21 is the coil 20,
It is supplied to the sheet 2 via 17 and rectified by the diode 19 and then smoothed, and the microprocessor 15 and the memory
Added to 16. Further, the microprocessor 15 has a ROM containing an initialization routine that is executed after the power is turned on, and further decodes the instruction code included in the serial pulse that has passed through the coils 18 and 22 to electrically erase the memory 16. Address, data and control signals to the
The memory 16 and the circuits 24-27 can mutually receive and transmit data via the coils 18, 22 and the interface 23.

As a result, for example, the above-mentioned matters that have been entered in the index card can be stored in the memory 16 using the keyboard 26, and the display device 27 can be used as necessary.
Can be displayed with. Further, the stored contents of the memory 16 can be used to easily perform the program reproduction at the time of reproduction, and also the timer recording, the cueing of the tape, and the like.

The microprocessor 15 in FIG. 1 may be provided in the recording / reproducing device 14. Alternatively, a means utilizing electrostatic capacitance may be used as a means for supplying power and communicating. Further, the present invention can be applied to recording / reproducing apparatuses using various cassettes such as cassettes for VTRs and tape recorders, and cassettes for floppy disks.

〔The invention's effect〕

Various items regarding the recorded contents of the cassette, especially timer information, can be stored in a large capacity in a contactless, highly reliable, electrically erasable memory. Based on this stored data, display, program reproduction, timer recording, cueing, etc. can be performed very easily.

It can be implemented without changing the model and standard of VTR and tape recorder, and tape format, and can be applied to conventional cassettes. Moreover, the organization of data can be unified. If the sheet 2 is mass-produced, the sheet 2 can be obtained at a relatively low cost, and there is no particular cost increase.
