Abstract

PURPOSE:To stop automatically recording and reproduction at preset time by providing a means for discriminating time which discriminates the lapse of the set time of optional duration and stopping the reproduction by a reproducing means and the record by a recording means 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, editting 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 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 activates the decks 6, 7 via an output circuit 14 for reproduction mode ON and an output circuit 15 for recording mode ON until the detected output of the residual time 0 is applied thereto. The recording and reproduction are thus automatically stopped by setting optional time in the above-mentioned way.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a signal recording and reproducing device that records a signal on a recording medium and reproduces the recorded signal from the recording medium, and related to recording functions.

[Prior Art] Generally, 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. A recording function was sometimes provided. Additionally, a playback function is sometimes provided that automatically stops playback when a recording medium such as a tape ends during playback.

However, the conventional playback stop function is designed to automatically stop only when the magnetic tape ends, and besides, unless it is mechanically stopped from playback, the power supply is also stopped. It wasn't done that way. Furthermore, the conventional playback stop function does not automatically stop playback by setting an arbitrary length of time.

As described above, conventional magnetic recording and reproducing apparatuses have the disadvantage that reproduction does not stop automatically unless the magnetic tape or the like is finished, and furthermore, unless it is stopped mechanically, the power source is not automatically stopped.

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

The present invention is directed to a signal recording/reproducing apparatus having a recording means for recording a signal and a reproducing means for reproducing a signal. In summary, the signal recording and reproducing apparatus according to the present invention includes a time determining means for determining the elapse of a set time of an arbitrary length, and a reproducing means for reproduction in response to the time determining means determining the elapse of the set time. and a second disabling means for stopping recording by the recording means in response to the time discriminating means determining that the set time has elapsed.

According to the signal recording and reproducing device of the present invention, it is possible to automatically stop recording and reproducing signals by setting an arbitrary length of time, and the operation can be performed automatically by setting an arbitrary length of time. 8 editing and copying functions are realized.

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.

In FIG. 1, at step $1, an arbitrary length of time is set. 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 continued. In step s3, the end of the tape, etc. is determined, or in step S4, the remaining set time is 0.
If it is determined that this is the case, the process moves 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 playback function that is the background of the present invention. In FIG. 2, a signal is reproduced in step S6, and the end of a recording medium such as a tape is determined in step S7. 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 S8 and the signal reproduction is stopped.

FIG. 3 is a flowchart showing an example of basic 4# of the automatic stop/reproduction function used in 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 by pressing one operation button to advance M in fixed time units, such as 0.58 (hour fal), IH, 1°5H, 2H, etc., or by pressing the time setting button. It may be performed arbitrarily and continuously at intervals of 1 minute. After the settings have been made, the process moves to step S'10 and the recording is played back. Of course, it is also possible to play back without setting the time as in the past. Subsequently, in steps 811 and 812, it is determined whether playback should be stopped.

In step 811, a recording medium such as a tape is
It is determined whether the end has been reached. If it is not the H end, the process moves to step S12, and it is determined whether 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, etc. has reached the end, or if it is determined in step s12 that the remaining set time is 0, the process moves to step 813, and the signal reproduction is automatically stopped. 6. In this case, the power may also be turned off at the periphery. Step 8
The determination in step 12 is made by subtracting the elapsed time from the set time and determining whether the remainder is O. Note that the time may be set again during subtraction. In this case, after resetting, 1 interval may be subtracted again.

As a result, it is determined whether the copy mode is set or not.
If it is not set, the process moves to step 816 and operations other than editing and copying are performed. If the switch sw is set to the edit/copy mode, the process moves to step 817, where an arbitrary length of time is set. Subsequently, in step 81B, the remaining set time is determined to be 0.
It is determined that the number t1 is O in step 819.
The process then proceeds to step S22, where signal reproduction and recording are performed. This operation is illustrated in blocks 1-5 of FIG. That is, the time 1Q constant timer is turned on as shown in block 2 by editing and copying switches 1 to 1 of the switches sw, and then the operating time is set (or changed) as shown in block 3. The remaining IFRIfl of the set time is detected by the time detector 4, and the detection output of the remaining time 0 is given to the control circuit 1 via the output circuit 5. The control circuit 1 activates the playback deck 6 and the recording deck 7 through the playback mode ON output circuit Wi14 and the recording mode ON output circuit 15, respectively, until the remaining 11tR O detection output is given. do.

Returning to FIG. 4, steps 819 and 822
Then, the process moves to step s20 and step 823, respectively, and it is determined whether the tape has reached the end 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 0. If not, the signals are played back and recorded in steps 819 and 822, respectively. It will be done. The video signal and audio signal thus reproduced on the reproduction deck 6 are recorded on the recording deck 7, thereby copying the signals. Further, by repeatedly copying the short-time setting, the m-east of the signal is performed.

In step 818, it is determined that the set time remaining is O, or in step 820 and step 823
If it is determined that one of the tapes has reached the end at step 821 and step 824, the operations of both decks 6 and 7 are stopped. In figure M5, the end of the tape is detected by tape end detection sections 16 and 18, and the detection outputs are sent to output circuits 17 and 19.
