Abstract

PURPOSE:To eliminate a recording omission and to utilize a timer reserved video effectively and correctly by sending a warning sound in the case of reserving the program that a picture recording time is over than the tape remaining quantity time. CONSTITUTION:When a magnetic tape is inserted, the signal of the tape remaining quantity time is transmitted from a tape remaining quantity detecting circuit 7 and the remaining quantity time in a standard mode is stored in a counting circuit 4 via a system control part 6 and timer part 3. The program reserving signal from a timer reserving operation key 1 or remote control receiver part 2 is inputted to the timer part 3. At this time, in the circuit 4 various speed modes are converted into the standard mode compared with the tape remaining quantity time and when the picture recording time is set longer than the tape remaining quantity time, the signal of an over picture recording time is sent to the timer part 3. Thus, the timer part 3 transmits a warning sound generation signal to a warning sound circuit 5, a warning sound is generated and the generation of a picture recording omission is notified in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a magnetic recording/reproducing device such as a video tape recorder having a timer scheduled recording function.

In particular, the present invention relates to a magnetic recording/reproducing device having a program reservation function without recording leakage.

[Conventional technology]

With conventional magnetic recording and playback devices of this type, if you set a long recording time (the remaining time) without knowing the remaining amount of time on the tape when making a timer reservation recording, the program will not be recorded for the time that exceeds the time. .

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, the timer reservation function and the remaining amount of magnetic tape are not taken into account in magnetic recording and reproducing devices such as video tape recorders. There was a problem that recording leakage occurred during the time period.

The purpose of the present invention is to compare the remaining time of the magnetic tape with the total time of each reserved program, and if the recording time is longer than the remaining time of the tape, a warning sound is sounded to prevent recording omissions. It is an object of the present invention to provide a magnetic recording/reproducing device that can be determined at the time of setting.

[Means for solving problems]

The above purpose was achieved by providing the timer scheduled recording function with a magnetic tape remaining amount detection circuit, an integration circuit that calculates the remaining tape amount and recording time, and a warning sound circuit that notifies you when the recording time is over. be done.

[Effect]

During timer scheduled recording, the remaining tape amount detection circuit detects the remaining amount of tape and stores it in the integration circuit. Furthermore, the integration circuit calculates the total recording time of each program,
This is compared with the remaining time of the tape, and if a program whose recording time exceeds the remaining time of the tape is reserved, a warning sound is sounded, thereby making it possible to determine whether there is any recording leakage at the time of reservation.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a video tape recorder showing an embodiment of the magnetic recording and reproducing apparatus according to the present invention, in which 1 is a timer reservation recording operation key, 2 is a remote control receiving section, 3 is a timer section, and 4 is an integration circuit. , 5 is a warning sound circuit, 6 is a system control section, and 7 is a tape remaining amount detection circuit.

In the figure, when a magnetic tape is inserted into a video tape recorder, a remaining tape amount detection circuit 7 outputs a signal indicating the remaining amount of time on the magnetic tape, passes through a system control section 6, a timer section 3, and is sent to an integration circuit 4. The remaining time in standard speed mode is memorized. Further, a program reservation signal is output from the timer reservation operation key 1 or the remote control receiving section 2 and is input to the timer section 3. Furthermore, the signal of the recording time of each program reservation from the timer section 3 is sent to the integration circuit 4.
is input. At this time, the recording time signal is transmitted to the integrating circuit 4.
The tape speed in the standard mode is converted to the standard mode as it is, the 3x mode is converted to the standard mode, and the tape speed is compared with the remaining time of the tape. If the converted recording time is shorter than the remaining tape time, the program reservation is accepted. If the recording time is set to be longer than the remaining tape time, the integration circuit 4 outputs a recording time over signal to the timer section 3 and inputs it to the timer section 3. Furthermore, the timer section 3
A warning sound generation signal is input to the warning sound circuit 5, and the warning sound circuit 5 sounds a warning sound to notify that recording leakage occurs.

FIG. 2 is an explanatory diagram illustrating the relationship between the remaining magnetic tape time and program reservations.

In the figure, it is assumed that the remaining time on the magnetic tape is 80 minutes. If the reserved program A is 40 minutes in the standard mode, the recording time is shorter than the remaining time, so the timer unit 5 accepts the reservation and the remaining time on the magnetic tape becomes 40 minutes. Next, if reserved program B is set to 3x mode and 60 minutes, the integrating circuit 4 converts the 3x mode to standard mode and the recording time becomes 20 minutes, and compares it with the remaining recording time. Similarly to A, since the remaining time is within the remaining time, the reservation will be accepted if the remaining time on the tape is 20 minutes. Continue further.

If reserved program C is set for 90 minutes in 3x mode,
Similarly, it is converted to standard mode and lasts for 30 minutes. The integration circuit 4 compares the remaining amount of magnetic tape with the recording time and determines whether the recording time has exceeded.

Upon receiving this discrimination signal, the warning sound circuit 5 sounds a warning sound,
Notifies that recording leakage occurs.

In this way, program reservations that exceed the remaining tape time, such as reserved program C shown in Figure 2, can be identified at the time of reservation setting. Can be used accurately.

〔Effect of the invention〕

As explained above, according to the present invention, program reservations in which the remaining time of the magnetic tape has been exceeded during timer reservation recording can be determined at the time of reservation setting, so recording omissions can be eliminated, and timer reservation recording can be made effective and effective. A magnetic recording and reproducing device that can be used accurately can be provided.
