Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape recording and reproducing apparatus having a tape continuous recording and reproducing function that is effective for long-time recording and reproducing.

BACKGROUND OF THE INVENTION In recent years, the number of long-running programs has increased, and devices with a timer-based absence recording function are becoming a trend.

Conventionally, this type of record of absences has generally been recorded on one tape. The configuration will be explained below with reference to FIG.

As shown in the figure, when recording your absence, use one roll of tape 6.
into the tape recording/reproducing device (hereinafter referred to as the main unit) and set timer 1 to the desired time.

At the preset time, a command is sent from the timer 1 to the system controller 3, which turns on the main power supply 2, and also sends a command to the servo 4 to rotate the motor 5 and start recording on the tape 6.

When the tape 6 reaches the end, the end of the tape is detected by the tape end detector 7 and a command is sent to the system controller 3.
After sending a command from the system controller 3 to the servo 4 to release the loading of the tape, the main power supply 2 is turned off.

Problems to be Solved by the Invention In such a conventional tape recording and reproducing device, when a tape with a short recording time or a tape that has already been recorded halfway and is to be recorded on the remaining portion is inserted into the main body, the recording of tape 6 is interrupted in the middle of recording. When the remaining portion of the program is completed, the tape end detector 7 indicates that the entire operation has been completed and the power is turned off, causing the program recording to be interrupted midway, resulting in the problem that not all of the desired programs can be recorded.

The present invention solves the above problems, and aims to provide a tape recording and reproducing apparatus that can realize continuous tape recording.

Means for Solving the Problems In order to achieve the above object, the present invention includes means for outputting a tape remaining amount detection signal as a standby signal, means for outputting a tape end detection signal as a start signal, and means for outputting a tape end detection signal as a start signal, and a stop signal from a timer. The apparatus is equipped with means for outputting, and means for inputting a standby signal, a start signal, and a stop signal from the outside.

According to the above-mentioned structure, when the first tape recording and reproducing device running out of tape during program recording, the second tape recording and reproducing device is preliminarily put into a standby state with a standby signal. It is possible to immediately continue recording with a start signal and to end recording with a stop signal.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

As shown in FIG.
The tape recording/reproducing apparatus main body 10 (hereinafter referred to as the second main body 10) operates in response to the signals. As shown in FIG. 1, the first and second main bodies 9 and 10 each include a circuit for generating a standby signal from the tape remaining amount detector 8 to the terminal d;
It is equipped with a circuit that generates a start signal from the tape end detector 7 to terminal A, and a circuit that generates a stop signal from timer 1 to terminal f, and a standby signal input to terminal C, a start signal input to terminal a, and a circuit that generates a stop signal from timer 1 to terminal f. A stop signal input is received at e.

To explain the operation in the above configuration, when recording the absence, first a command is sent from the timer 1 of the first main body 9 to the system controller 3, the main power supply 2 is turned on, a command is also sent to the servo 4, and the motor 5 starts rotating. Recording on the tape 6 is then started. When the tape 6 approaches the end, a signal is sent from the tape remaining amount detector 8 to the system controller 3 to notify that the preset amount of tape has been reached, and the signal is output from the terminal d to indicate the standby state and is sent to the terminal of the second main body 10. C and puts the second main body 10 into a standby state where recording can be started immediately. When the end of the tape is reached, a command or a start signal is sent from the tape end detector 7 to the system controller 3, and a start signal is transmitted from the terminal of the first main body 9 to the terminal a of the second main body 10 to start recording in the main body 10. When the recording end time set in timer 1 is reached, a stop signal from system controller 3 or the first
The signal is transmitted from the terminal f of the second main body 9 to the terminal e of the second main body 10, and the recording ends.

As described above, according to the tape recording and reproducing apparatus of the embodiment of the present invention, two or more main units are connected, and a standby signal from the tape remaining amount detector 8 of the first main unit 9 and a standby signal from the tape end detector 7 are output from the tape end detector 7. System controller 3 sends a start signal and a stop signal when the end time set in timer 1 is reached.
Since the output terminals d, b, and f are arranged to be transmitted to the corresponding terminals of the second main body 10, two or more recording devices can be operated continuously in real time, allowing long-term recording. can be achieved.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, at least two or more recording devices are connected, and the next device operates serially in response to a tape end detection signal from the preceding device. Because they are arranged in such a way, they are suitable for long-term recording, and even when using a tape with a short recording time or a tape that has already been recorded halfway, tape recording can be performed without interruption. We can provide playback equipment.
