Description

[Detailed description of the invention] This invention relates to an automatic tape editing device, which controls the playback device side when editing and recording a playback signal from a source deck, CD (compact disc) player, etc. to an editing deck. This relates to a system that allows the recording deck to be automatically controlled using signals.

In general, magnetic tape editing requires at least two
It was extremely difficult for one person to do this, as it required a deck, a playback device such as a CD player, and a deck, and complicated operations between them.

Therefore, this idea was made in view of the above points, and the deck → deck and CD player →
An extremely good automatic tape editing device that has been improved so that it can automate complicated tape editing and can be easily performed by one person by having a configuration that allows the playback side to automatically control the recording side when dubbing to a deck, etc. is intended to provide.

Hereinafter, a basic example of this invention will be explained in detail with reference to the drawings.

That is, in Figure 1a, PCM (a type of digital recording and playback using a pulse code modulation method) deck 11 is used as a source deck (on the playback side), and also for editing (in this case, dubbing). (Recording side) Same as above as deck
PCM deck or VTR (video tape recorder)
12 shows a schematic configuration when using 12.

In addition, in Figure b, a PCM deck 11 similar to the one described above is used as a deck for source (playback side), and a cassette tape deck 13 is used as a deck for editing (in this case dubbing) (recording side). The diagram shows a schematic configuration when

Here, in any case, the PCM deck 11, which is a source deck, is a video (digital)
System input/output terminals (VIDEO-IN/OUT) and analog system line input/output terminals (LINE-IN/OUT)
In addition to OUT), it also has control input/output terminals (CONT-IN/OUT) for controlling the editing deck, as well as operation signals from various operation keys (not shown) and a program (multi-track) tuning controller. For example, it is assumed that an IC-based controller is included in order to control the tape drive mechanism from itself and the editing deck based on control signals from the tape editing unit, but the controller is a dedicated tape editing unit. It may be configured differently.

In the case of FIG. 1a, the PCM deck or VTR 12 serving as the editing deck has the same configuration as the PCM deck 11 serving as the source deck described above, and the video output terminal (VIDEO-
OUT) is connected to the video input terminal (VIDEO-IN) of the former as a music signal line, and the control output terminal (CONT-OUT) of the latter is connected to the control input terminal (CONT-IN) of the former as a control signal line.
It is connected to the.

This makes it possible to perform dubbing in which a digital (PCM) playback signal reproduced from the PCM deck 11 serving as a source deck is digitally recorded on the PCM deck or VTR 12 serving as an editing deck. . In this case, the control signals given from the former to the latter control the latter's necessary operations, such as recording start and end operations, and the operator only has to operate the former, and the rest is automatic. The feature of this invention is that the latter can be controlled.

In addition, in the case of Fig. 1b, the cassette tape deck 13 serving as the editing deck is equipped with a control input terminal (CONT-IN) in addition to the normal line input/output terminals (LINE-IN/OUT). , the line output terminal (LINE-OUT) of the PCM deck 11, which serves as a source deck, serves as a music signal line, and the control output terminal (CONT-OUT) serves as a control signal line, respectively, and each of the cassette tape decks 13 serves as an editing deck. Line input terminal (LINE
-IN) and the control input terminal (CONT-IN).

As a result, the analog playback signal reproduced from the PCM deck 11, which is a source deck, can be dubbed to the cassette tape deck 13, which is an editing deck, in such a way that it is recorded in analog form. The control operation is the same as in the case of FIG. 1a.

Figure 2 shows a specific example of the control system in the above basic example. ), recording system muting (REC-MUTE), stop (STOP), and pause (PAUSE) input terminals are connected to the corresponding operation keys K1 to K7, among which (REW), (PLAY) ,

Each output terminal of PAUSE) is connected to each corresponding input terminal of a tape drive mechanism control circuit (not shown), and necessary output terminals thereof are connected to a predetermined portion of the control circuit 24, as will be described later.

Here, the control circuit 24 is connected to the controller 22.

The control circuit 24 also has an OR gate 244 whose input terminals are connected to the output terminals of the first and second AND gates 241 and 242 in correspondence with the output terminals of the NOR gate 243 and the output terminal of the controller 22.

Further, the control circuit 24 controls the OR gate 24.

The emitters of Q1, Q2, and Q3 are grounded, and their collectors are connected to the control output terminals T1, T2, and T3, respectively, and the collector of Q1 is connected to the control output terminal T through a diode D with the polarity shown.
Connected to 4.

Note that the control output terminal T5 is grounded, and (GND) and (Vcc) of the controller 22 are connected to the ground and the power source as a ground terminal and a power supply terminal.

On the other hand, each input terminal of the controller 32 included in the editing deck 31 is connected in the same manner as the controller 22 included in the source deck 21 described above, and among them, (PAUSE),
(FF), (STOP), (REC-MUTE) and (GND) input terminals are control input terminals T11, T1
2, T13, T14 and T15.

In the control system configured as described above, the program (multi-track) controller 2 included in the source deck 21 (a separate configuration is also possible)
Assume that a dubbing is performed by specifying a song among the songs recorded as shown in FIG.

That is, first, the program (multi-music) selection controller 23 sends control signals necessary for the preset contents based on the specified operation to the controller 22 included in the source deck 21. In this case, as shown in the upper row of Fig. 4b in correspondence with a, the start position (START) is
A signal for fast forwarding (queuing) the track from the beginning of the track is supplied to the (FF) input terminal, then a signal for controlling the track is supplied to the (PLAY) input terminal, and furthermore, a signal for rewinding to the beginning of the track (review) is supplied to the (FF) input terminal.
A signal for controlling the song is supplied to the (REW) input terminal, and finally a signal for controlling the song is supplied to the (PLAY) input terminal.

As a result, the controller 22 derives the signals necessary for the operation of controlling the track from the corresponding output terminal, and as a result, the tape drive mechanism control circuit (not shown) is activated, and thus the source deck 21 is controlled. make such movements happen.

At the same time, each output signal from the controller 22 is sent to the corresponding input end of the controller 31 on the editing deck 31 side via the control circuit 24 and control signal lines L1 to L5, but in this case, the fast forward The control circuit 24 outputs signals during playback (queue) and rewinding (review) to pause (PAUSE) and recording system muting (REC-MUTE), and output signals during playback enter recording (REC). Ru.

However, the source deck 21 side controller 22
is (0.FF) and (0.PLAY) when cueing
The output terminals are both set to "H" level, and the (0.REW) and (0.PLAY) output terminals are both set to "H" level during review.

As a result, as shown in the lower part of FIG. 4b, the editing deck 31 is in the (PAUSE) or (REC-MUTE) state while the source deck 21 is in the queue or review mode and is in the (REC-MUTE) state. When the deck 21 completes channel selection and enters the (PLAY) state, it automatically enters the (REC) state, thereby making it possible to perform dubbing based on the designation of the track, as shown in FIG.

In addition, after the specified dubbing is completed, both the source deck 21 and the editing deck 31 stop (STOP).
Of course, it will become a state.

FIG. 5 is a diagram showing the above operation in the form of a timing chart.

By the way, in the above-mentioned basic example of an automatic tape editing device, if the editing deck is a cassette tape deck, the REC state is reached relatively quickly when a recording command signal to (REC) arrives. Therefore, it is not much of a problem, but it is PCM
In the case of a deck, VTR, etc., even if a recording command signal to (REC) arrives, it does not enter the REC state immediately, but only after a certain period of time has elapsed. This tends to cause the problem that the beginning of the reproduced signal is not recorded and is omitted.

Next, an embodiment of this invention, which is an extension of the basic example described above in consideration of the above-mentioned problems, will be described with reference to FIG.

That is, FIG. 6a shows the source deck 21' side of the control system shown in FIG. 2, and the same reference numerals are used to denote the same parts as in FIG. 2, and the explanation thereof will be omitted. Then, in FIG. 6a, (0.
The difference from FIG. 2 is that a recording control circuit 25 is attached to the (PLAY) command signal line from the (PLAY) output end.

Here, the recording control circuit 25 includes an OR gate 252 whose output terminals are respectively connected to an output terminal of an OR gate 244 in the control circuit 24 described above and an output terminal of an inverter 251 which will be described later, and an output terminal of this OR gate 252. It has an AND gate 253 whose input terminals are connected to the (0.PLAY) output terminal of the controller 22 described above, and the output terminal of this AND gate 253 is connected to the (0.PLAY) output terminal described above.
It is now used in place of the (PLAY) command signal line from the (PLAY) output terminal.

In addition, the input terminal of the inverter 251 in the recording control circuit 25 is connected to the power supply Vcc via a resistor R4.
It is also connected to the recording control jack J.

Here, a recording control plug P is selectively connected to the recording control jack J, and when the editing deck 31' side is completely in the (REC) state, the recording control plug P is connected to the recording control jack J. A micro switch 35 to be opened is connected.

FIG. 6b shows an example of mounting the micro switch 35 on the editing deck 31' side.
This is a case where the system is configured to be in an open state.

In the above configuration, when dubbing, the recording control plug P can be connected selectively depending on the model of the editing deck 31', and if the editing deck 31' is connected to the cassette tape In the case of a deck, the same dubbing operation as in the above-mentioned basic example can be performed without connecting the plug P. This is because, as mentioned above, if the editing deck 31 is a cassette tape deck, it can be brought into the (REC) state almost simultaneously with the arrival of the recording command signal to (REC).
This is because there is no problem in putting the source deck 21' in the (PLAY) state immediately without any control.

If the editing deck 31' is a PCM deck or a VTR, the recording control plug P may be connected to the recording control jack J on the source deck 21' side. That is, as a result, on the source deck 21' side, the PLAY command signal from the (0.PLAY) output terminal of the controller 22 is edited by the recording control circuit 25 without being immediately supplied to the tape drive mechanism control circuit. After the micro switch 35 on the deck 31' side is closed, the water is supplied. In other words, this prevents an undesirable situation in which the playback signal from the source (playback) deck 21' is recorded without the head part as in the case where the recording control circuit 25 is not provided. This makes it possible to properly record the head portion of the reproduced signal without causing such occurrence.

FIG. 7 is a diagram showing the above operation in a dynamic diagram.

The above-mentioned automatic tape editing device is particularly effective because it can be applied to PCM decks (VTRs) that handle a larger amount of data than conventional tape editing devices, and the editing work can be done easily and accurately. However, it is still effective when applied to ordinary tape decks (including cassettes).

Furthermore, this invention is not limited to the embodiments described above and illustrated; the control circuit may be configured with a microcomputer, and the playback device that plays back the signals recorded on the editing deck may be a CD player. It's okay.

Therefore, as detailed above, according to this invention, by configuring a device that plays back signals on the playback side to automatically control the deck on the recording side, complex tape editing can be automated and easily done by one person. It becomes possible to provide an extremely good automatic tape editing device that has been improved so as to be able to perform the following operations.
