Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape device used in a video cassette recorder (hereinafter referred to as VTR) or the like.

[0002]

2. Description of the Related Art In recent years, VTRs have been strongly required to have high functionality and high operability. Especially, it is particularly strong in the reproducing operation and the recording operation which are frequently used in the VTR operation. It is necessary to respond to the improvement of VTR operability in response to such needs.

Conventionally, a VTR has a fast-forward (FF), rewind (REW), fast-forward playback (CUE), and fast-reverse playback (RE) in order to find a tape position to be played or recorded.
Functions such as VIEW) were installed. Further, as an improvement of the recording operation, a program recording function for programming a plurality of contents to be recorded in advance and automatically recording the contents in order has been installed to improve the operability of the VTR.

FIG. 3 shows an operation block diagram of a conventional VTR.
Further, FIGS. 2A and 2B are conceptual views of the tape conceptually showing the position on the tape and the recorded contents when the program recording or reproducing operation is performed.

In FIG. 3, a VTR has various types of operation switches 10, such as a PLAY switch 12 and an FF switch 1.
4, REW switch 16, CUE switch 18, REV
An IEW switch 20, a STOP switch 22, a program recording switch 24, and the like are prepared, and the control circuit 30 is operated by operating any of the operation switches 10.
Can control the mode switching means 32 to switch the VTR mode.

The operation of the conventional VTR constructed as described above will be described. The VTR is in the program recording mode, and the tape has a program recording function.
As shown in (a), programs A, B, C, and D have already been recorded. Also, in the program, after program D, program E,
It is set to record F and G. The operator can view the recorded programs A, B, C, D now by pressing V
The program recording mode of TR is temporarily released, the tape is rewound to the As position at the start end by the REW switch 16, and then the reproduction mode is switched by the PLAY switch 12. However, at the time when the tape is being reproduced up to the Bm position, if the operator is unable to take time to continue the reproduction for the convenience of the operator, the program B and the areas after the Bm position of the program B are not erased, and the program D is recorded. Attempts to record the programs E, F, and G from the De position on the tape, which is the final position. In that case, the operator fast-forwards the tape with the FF switch 14, stops the tape transfer with the STOP switch 22 when it is considered that the tape is almost at the De position, and then reproduces the tape with the PLAY switch 12. In most cases, it deviates from the De position. If it deviates significantly, FF switch 14, REW switch 16, STOP switch 22
To operate. If the tape is moved to the approximate De position, then the CUE switch 18 or REVIEW switch 20 is used to move the tape to D
Move to position e and then switch to program recording switch 2
By switching the VTR to the program recording mode from No. 4, it is possible to record the programs E, F, and G after the program D as shown in FIG. 2B.

Further, when the operator intends to reproduce again from the Bm position of the tape of the program B after the recording of the programs E, F, and G by the program recording function, the program recording mode is temporarily released and the tape is recorded. In the same manner as when searching for the De position of, the various operation switches 10 are repeatedly operated to search for the Bm position of the tape. After that, the VTR is switched to the reproduction mode by the PLAY switch 12, so that the reproduction from the Bm position of the tape becomes possible.

[0008]

However, in the above-mentioned conventional structure, various operation switches have to be repeatedly operated to find the De position and the Bm position of the tape, which makes the operation complicated. In addition, it has a problem that it takes a long time to operate and is very inconvenient.

[0009]

In order to achieve this object, the tape device of the present invention uses a continuous recording switch and each operation switch to record a program when the program recording mode is switched to another mode. By operating the storage means for storing the last tape position of the last recorded contents in the mode and the continuous recording switch, the tape is moved to the tape position stored in the storage means, and then the program recording means is controlled. It has a structure of continuous recording control means for switching the apparatus to the program recording mode.

Further, in the tape device of the present invention, when the continuous reproduction switch and each operation switch are operated to switch from the reproduction mode to another mode, the last tape position of the content reproduced last in the reproduction mode is stored. By operating the storage means and the continuous reproduction switch, the tape is transferred to the tape position stored in the storage means, and then the mode switching means is controlled to switch the apparatus to the reproduction mode. Have

[0011]

According to the present invention, the last tape position of the last recorded content is stored in the program recording mode by the above configuration, and when the reproduction mode is switched to another mode, the last tape content reproduced in the reproduction mode is recorded. Since the tape position is stored, no matter what mode the VTR is used by the operator, or whatever position the tape is being transferred, by operating one operating switch,
Easily transfer the tape to the desired tape position in a short time.
