Abstract

PURPOSE:To prevent double writing and not to erase the previous picture recording contents, by providing a titled device have a function which is capable of easily detecting the end of a recorded part. CONSTITUTION:When a search switch 24 is turned on, a signal (a) inputted to an S terminal of the first flip-flop 25 becomes an ''H'' level, and an output (d) of a Q terminal of the first flip-flop 25 is inverted to an ''H'' level. When a CTL signal is inputted to a retriggerable monostable multivibrator 23, an output (c) of the retriggerable monostable multivibrator 23 becomes an ''H'' level. When fast forwarding advances and passes through the last position of a recorded part, the signal (c) falls at the point of time after a prescribed time decided by a time constant of the retriggerable monostable multivibrator 23 from the point of time when the last one of the CTL signal has been detected. When said signal falls, the output (d) of the Q terminal of the first flip-flop is changed to an ''L'' level, and a motor 27 driven by a motor driving circuit 26 is stopped.

is installed on. At the start of recording, a key signal of 50 Hz is sent to the key head 15 for 0.5 to 1 second through the amplification 512 m, and the key signal is recorded by the key head 15 at the beginning of the record. On the other hand, when attempting to reproduce, when a key signal is detected by the key head IS during rewinding, the key signal is amplified by the amplification 1112b and shaped into a wave by the waveform shaping circuit 13. When the waveform-shaped signal is input to the play terminal of the control circuit 14, the control circuit operates to generate 41j! L is stopped at t9, and the reproducing operation is started.

In a magnetic recording/reproducing device having such a quay,
During playback, recorded images can be taken out, but after rewinding the magnetic tape and playing back a part of the previously recorded 1iii, a new image is inserted into the unrecorded portion following the end of this 3. When trying to record an image, it is difficult to mark the end of the image, that is, the end of the recorded part. Also, if you accidentally perform a recording operation in the middle of a previously recorded image, a new image may be written on top of the previously recorded image, or the previously recorded image may be erased and the erased portion The disadvantage was that a new image was recorded.

Now, in the process of recording on the magnetic tape 21, in the middle of recording, 11 kll is pressed once and temporary playback is performed.
After checking what kind of pictures have been recorded, you must record again from the beginning OIi of the unrecorded part that follows the recorded part! Suppose that he planes. For example, suppose that when recording has been performed up to position C of prosthetic tape=1 in FIG. 5, it becomes necessary to review what was previously recorded. In such a case, recording is temporarily stopped at position C, and the magnetic tape 21 is rewound at a predetermined position Dt. Then, the playback operation starts from the position. Playback is performed at a predetermined position Et,
If the later recorded portion does not need to be reproduced, the magnetic tape is fast-forwarded to position C, the last of the recorded portion, and new recording begins from position C.

When such an operation is carried out using the circuit shown in FIG. 4, first a nine-rewind command is issued by a well-known means (not shown), and the magnetic tape 21 is rewound to a predetermined position. and,
After playing a predetermined image, search switch 24 in FIG.
Turn on. If the time point when the search switch 24 is turned on is t as shown in Fig. 6, the signal a input to the 6 (set) terminal of the 7 lip-flop 25 of rattan 1 will be at the 1Hl level as shown in Fig. 116 (a). Nashi, first 7 lip 7
The Q terminal output d of the 0 knob 25 is inverted to the %HI level.
As a result, the motor drive circuit 26 drives the motor 27, and fast forwarding is started. When fast forwarding starts, the CTL signal detection head 22 starts detecting the CTL signal, and when the CTL signal as shown in FIG. Becomes HI level. When fast forwarding passes the last position of the recorded portion (Fig. 5C), the CTL signal is no longer detected, so at the time t4 when the CTL signal O is detected, the triggerable mono i 1 at a time t after a predetermined time determined by the multi-time constant 230.
