PURPOSE:To set optional time and to stop automatically reproduction by providing a means for discriminating time which discriminates the lapse of the set time of optional duration and providing a means for inactivation which stops reproduction in response with the timing when the lapse of the set time is discriminated. CONSTITUTION:A deck 6 for reproducing and a deck 7 for recording are provided. The video signal and sound signal from the deck 6 are applied to the deck 7. A mode selection switch SW is set to an editing and copying mode and the operation is started to execute automatic stopping, editing and copying. A time set timer is first turned ON 2 then the operation time is set or changed 3. The residual time of the preset time is detected in a part 4 for detecting the residual time and the detected output for the residual time 0 is applied via an output circuit 5 to a control circuit 1. The circuit 1 inactivates the decks 6 via an output circuit 14 for reproduction mode ON when the detected output for the residual time 0 is applied thereto. The reproduction is thus automatically stopped by setting optional time.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a signal reproducing device that reproduces signals recorded on a recording medium, and particularly relates to an automatic stop reproduction function thereof.
It's true.

"Prior Art" In general, in conventional magnetic recording and reproducing devices such as video tape recorders, an operator sets an arbitrary length of time, and when that time elapses, recording is stopped and the power is turned off. The recorded recording function was sometimes delayed. In addition, a playback function is sometimes provided in which playback is automatically stopped when the recording medium such as the magnetic chip 7 reaches the end during playback.

However, the conventional playback stop function only automatically stops when the magnetic tape ends.
Moreover, except for those that mechanically stop playback, Nu
It was not planned that this would result in a suspension. Furthermore, conventional playback stop functions do not automatically stop playback by setting an arbitrary length of time.

As described above, in signal reproducing devices including conventional magnetic recording and reproducing devices, reproduction does not automatically stop until the magnetic tape or the like ends, and furthermore, unless it is stopped mechanically,
There was a drawback that the power supply was not automatically shut off.

[Summary of the Invention] The present invention has been made in order to eliminate the above-mentioned drawbacks of conventional devices.

In summary, the signal reproducing device according to the present invention includes a time determining means for determining the elapse of a set time of an arbitrary length for which reproduction is to be performed, and a signal reproducing device that performs reproduction in response to the time determining means determining the elapse of the set time. and disabling means for stopping the operation.

According to the signal reproducing device of the present invention, it is possible to set an arbitrary length of time and automatically stop signal reproduction.

The above objects and other objects and effects of the present invention will become more apparent from the following detailed description with reference to the drawings.

[Embodiments of the Invention] FIG. 1 is a flowchart showing the basic configuration of a conventional automatic stop recording function that is the background of the present invention. In FIG. 1, an arbitrary length of time is set in step S1. Subsequently, in step S2, a signal is recorded. In step S3, the end of the recording medium such as a tape is determined, and if it is not the end, the process moves to step S4.

In step S4, it is determined whether the remaining time of the time set in step S1 is O. If it is not 0, the process returns to step S2, and recording of the signal is performed successively. If it is determined in step S3 that the end of the tape or the like is determined, or if it is determined in step S4 that the remaining set time is O, the process proceeds to step S5 and recording of the signal is stopped.

FIG. 2 is a flowchart showing the basic configuration of the conventional automatic stop and regeneration function which is the yellow phosphorus of the present invention. In FIG. 2, signal reproduction is performed in step S6,
In step S7, &! of the tape, etc. The end of the recording medium is determined. If it is not the end, the signal is reproduced again in step S6, and if it is the end, the process moves to step 88 and the signal reproduction is stopped.

FIG. 3 is a flowchart showing an example of the basic configuration of the automatic stop playback function according to the present invention. The portions within the broken lines are added to the conventional playback function in FIG. This makes it possible to perform playback for an arbitrary period of time and then automatically stop the playback.

In FIG. 3, an arbitrary length of time is set by the operator in step S9. This setting may be made sequentially by pressing one operation button in units of 5#, such as 0.5H (time>, 1H, 1°5l-L2+-1, etc.), or by pressing the time setting button. This may be done continuously at a rate of about 1 minute per hour).

After the settings are made, the process moves to step S10 and the recording is played back. Of course, it is also possible to play back without setting the time as in the conventional case.

Subsequently, in step Sl 1tt9 and step 812, it is determined whether the reproduction should be stopped.

In step 811, it is determined whether the recording medium such as a tape has reached its end. If it is not the end, the process moves to step 812, and it is determined whether or not the remaining set time is O. If it is not O, the process returns to step 810 and signal reproduction continues.

If it is determined in step 811 that the tape or the like has reached the end, or if it is determined in step 812 that the remaining set time is 0, the process moves to step S13 and the reproduction of the signal is automatically stopped. . In this case,
The power may also be turned off at the same time. Step 81
The determination in step 2 is made by subtracting the elapsed time from the set time and determining whether the remainder is O.

Note that #darkness may be set again during subtraction. In this case, after resetting, the time can be subtracted again.

FIG. 4 shows White ill! using the automatic stop playback function according to the present invention. + It is a flowchart which shows an example of the basic structure of a stop Tachibana Higashi and a copy production function. This usage example is the first
This is a combination of the automatic stop recording function shown in the figure and the automatic stop playback function shown in Fig. 3. This allows you to set an arbitrary time to edit and copy signals, and then automatically stop the operation. becomes possible.

FIG. 5 is a schematic block diagram showing an example of a specific configuration for realizing the functions shown in FIG. 4. The signal recording and reproducing apparatus using the present invention shown in FIG. 5 is, for example, a video tape recorder, and includes a reproducing deck 6 and a recording deck 7. The video and audio signals from the reproduction deck 6 are applied to the recording deck 7, where editing and copying operations are performed. The automatic stop collection and copying function will be described below with reference to FIGS. 4 and 5.

In step 814, the mode changeover switch SW is
The camera is set to s and m photo modes and starts operating. At step 815, it is determined whether the switch SW is set to edit or copy mode. If it is not set, the process moves to step 816 and operations other than tag and copy are performed. If the switch SW is set to cold weather and close-up mode, the process moves to step 817.
An arbitrary length of time is set. Subsequently, in step 818, it is determined whether or not the remaining set time is O. If not, the process proceeds to step 819 and step 822, where the signal is reproduced and recorded. This operation is illustrated in blocks 1-1 of FIG. That is, by setting the switch SW to wAs, copy, the time setting timer is turned on as shown in block 2, and then set (or changed) to open when operating as shown in block 3.
will be carried out. The remaining one hour of the set time is detected by the eel remaining time detection section 4, and the detection output of the external tooth time O is given to the control circuit 1 via the output circuit 5. The control circuit 1 controls the playback deck 6 through the playback mode ON output circuit 14 and the recording mode ON output circuit 15 until the remaining IT time 0 detection output is given.
and activates the recording deck 7.

Prior to activating the playback deck 6 and the recording deck 7, the operator must first load a cassette tape into each deck. A signal representing the state is given to the control circuit 1 via the cassette presence detection sections 8 and 10 and the output circuits 9 and 11. If no cassette is stored, the control circuit 1 activates the playback mode ON output circuit 14 and the recording mode ON output circuit 15, so that decks 6 and 7 are activated. The operation modes 8 and 7 are detected by the respective operation mode detection sections 12 and 13, and when the playback or recording mode is canceled, the control circuit 1 turns on the playback mode ON output circuit 14 or the recording mode ON output circuit 15. 1, and disables the playback deck 6 or the recording deck 7. If the erasure prevention tab of the cassette tape in the recording deck 7 is broken, it is detected by the accidental erasure prevention tab fold detection section 21, The detection signal is applied to the control circuit 1 via the output circuit 22, and the recording deck 7 is not activated.

Returning to FIG. 4, step 819 and step S22
The process then proceeds to steps 820 and 823, respectively, where it is determined whether the end of the tape has been reached on each deck. If none of the tapes has reached the end, the process returns to step 818 and it is determined whether the set time remaining is O. If not, the signals are played back and recorded in steps 819 and 322, respectively. . The video and audio signals thus reproduced on the playback deck 6 are recorded on the recording deck 7, thereby copying the signals.Also, by repeatedly copying the short-time settings, , signal editing is performed.

In step 818, it is determined that the set time remaining is O, or in step S20 and step 823
If it is determined that one of the tapes has reached the end in step S21 and step 824, the operations of both decks 6 and 7 are stopped. In FIG. 5, the end of the tape is detected by tape end detectors 16 and 18, and the detection outputs are output from output circuits 17 and 19.
The signal is applied to the control circuit 1 via the control circuit 1. Remaining time O
Or at the end of the tape, the control circuit 1 outputs the playback mode ON output circuit 14 and the recording mode ON output circuit 1.
