Abstract

PURPOSE:To vary automatically and properly the time to the next reproduced sound, namely, a repeat time by running and reproducing a tape if the voice from a microphone is interrupted when the tape is stopped temporarily with a repeated reproducing indicating signal. CONSTITUTION:If the blank part of reproducing is detected during rewinding, the high level is inputted to a differentiating circuit 20; and when the depession of a push-button 16 is released, the tape is run a certain speed to obtain a reproduced signal. When the push-button 16 is depressed during the reproducing, the tape is rewound, and reproduced words can be repeated during the rewinding. If the push-button 16 is depressed and when the blank part is detected, tape running is stopped temporarily; and if the voice input from a microphone 37 is interrupted, the output of an inverter 42 becomes high-level because of the closing of a switch 41, and the tape is run at a certain speed. When the push-button 16 is released, the reproducing state of tape running at a certain speed is set. Consequently, reproduced words can be repeated during the temporary stop time, and the time of release of the push-button 16 is selected to select properly the repeat time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a repeat playback device for a tape player or the like, and is suitable as a repeat playback device for a so-called LL device for language learning.

Generally, in a repeat playback device at LL, when the repeat playback operation fA is pressed, the magnetic tape is rewound and a playback signal from the rewound magnetic tape is obtained, resulting in a so-called cue state. The fact that the repeat signal in the cue state has disappeared, the RLI word breaks, blank spaces, and the target are "I".
When it is detected that the beginning of the word "am a boy J" is reached, the magnetic tape is automatically made to run at a constant speed due to this detection, and a reproduction signal is obtained by this running. “I am a boy J l:@
However, there is a known device in which the magnetic tape is rewound again as described above by pressing the operation button at the appropriate location.

In such a LL device, after listening to the playback signal and pressing the operation button until the next playback signal is obtained in automatic fishing, the learner also learns the words of the playback signal. However, as mentioned above, the time it takes to obtain the next reproduction signal is not necessarily equal to the time required for the next reproduction signal, and if the turn is repeated many times, There is a drawback that the next reproduction signal is automatically obtained.

Conventionally, in order to eliminate the above-mentioned drawbacks, the magnetic tape is rewound by pressing the operation button, and when the blank area is detected, the running of the magnetic tape is temporarily stopped, and the setting is performed manually in advance. A system is known in which the next reproduction signal is automatically obtained after the specified time has elapsed.

By the way, if the Km recitation time is set in advance in this way, it is not necessarily suitable for the rear axle, and there is a drawback that excess or deficiency may occur.

The present invention provides a repeating recirculation device for a tape player, etc., which is capable of selecting a longer time for automatic fishing in order to obtain a sufficient amount of time for the rear axis as described above, and to prevent the time from becoming redundant. This is what we provide.

FIG. 1 is a block diagram for clearly showing the configuration of the present invention.

When the repetitive playback operating means, such as a push button, is manually operated, this operation is detected and the rewinding means is operated, thereby rewinding the magnetic tape. In this state, when a signal for repeatedly reciprocating is obtained, the temporary stop means is operated and the magnetic tape is temporarily stopped. When the audio signal from the microphone disappears during the queen's temporary stop, the traveling means becomes operational and the magnetic tape is run at a constant speed, entering the reproduction state. Therefore, after operating the operating means, when the sound from the microphone disappears, the 6th generation state is reached, so the time from operating the operating means until the next reproduced sound is obtained, that is, the time on the rear axis described above. It can be automatically varied as appropriate.

An embodiment of the present invention will be described below with reference to FIG.

In the 21st operation, 1 is a magnetic tape, and the tape is pressed by a pinch roller 3 against a capstan 2 rotating at a constant speed and run at a constant speed. Also, this tape 1 is on reel 4
The film is wound at high speed and rewound (at this time, the pinch roller 3 is separated from the capstan 2). A magnetic head 5 is brought into contact with the tape 1 to obtain a reproduced signal from the tape. This reproduction signal is amplified by an amplifier 6.7 and output as sound from the speaker 8.

Reference numeral 9 denotes a control circuit, which is composed of a relay circuit, a logic circuit, a microcomputer, etc., and when a reciprocating operation switch 1O or the like is operated, a high level rHJ is inputted from the power supply 1B to the reciprocating terminal via resistors R1 and R3. The drive system 11 for the tape 1 is controlled so that the pinch roller 3 is brought into pressure contact with the capstan 2 via the tape Ik and the reel 4' is driven to run the tape 1 at a constant speed. 12
1 is a rewind operation switch, and when this operation is performed, the drive system 11 is controlled by the control circuit 9 so that the reel 4 is driven at high speed and the tape 1 is rewound.

13 is a temporary stop operation switch, 14 is a stop operation switch, and 15 is a fast forward operation switch.

The above configuration is well known as a tape recorder (player). Reference numeral 16 indicates a push button for repeat playback operation, and by pressing this push button 16, switch 17.1 is activated.
8 are both switched to the side shown by the broken line, and when the push button 16 is released, the KtII# is configured so that it returns to the side shown by the real leg. 19.20.21.22 shows a differential circuit 12iY composed of a resistor and a capacitor, 25.26
is an and gate, and 4,28 is an or gate.

4 is an R87 lip with 70 tubes, (9), 31.42 is an inverter, and 32 is a delay circuit. Hello, HE4 is back after 6 amps! This is an all-white detection circuit that detects the breaks between notes in a sound, and is composed of an integrating circuit and the like, as is well known. The key is a counter '0' detection circuit, which detects when the well-known tape counter that counts up (or down) as the tape runs reaches zero. , 34 are selectively supplied to the differentiating circuit section via a manual changeover switch 36. 37 indicates a microphone, and the audio signal from the microphone is amplified by an amplifier A, and is amplified by a diode 39. Envelope detection is performed, and this is input to a comparator via a filter to detect the presence or absence of sound from the microphone 37.This detection output is sent to the switch 4]
When the signal is on, the signal is supplied to the differential batch circuit ρ via the inverter 42.

In the repeat playback device configured as described above, switch 3
Actually 111 on 6! side, and switch 41)j(I
When push button 16i is pressed with J released, switch 17
゜18 is switched to the solid line side, a voltage is applied from the power supply 1B to the differentiating circuit 19 via the switch 18, this is differentiated by the differentiating circuit 19, rHJ is applied to the rewind terminal of the control circuit 90, and the switch 12 is The magnetic tape 1 is rewound in the same manner as when it is closed.

When a blank part of the signal reproduced from the reproduction head 5 is detected by the detection port w133 during rewinding of C, rHJ is inputted to the differentiation circuit section, and this is differentiated to produce an ant game)24.
25. At this time, when the push button 16 is released, rHJ is applied to the AND gates from the power supply 1B via the switch 17, and low level rLJ is applied to the AND gate 5 via the inverter 31. . Therefore, the differential pulse from the differential circuit section is the AND gate 2
27 Y: Passes through and is input as an rHJ pulse to the regeneration terminal of the control circuit 9 described above.

This causes the tape to run at a constant speed, and a reproduced signal from tape l is obtained. If the push button 16 is pressed during this playback, the tape 1 is rewound in the same manner as described above, and during this rewinding, the above-mentioned reproduced words can be digitized.

If the push button 16 is pressed as soon as the blank area is detected, the AND gate δ
rHJ is applied to the differential circuit 20' and the differential pulse passes through the AND gate 25 and is input to the temporary stop terminal of the control circuit 9, and the running of the tape 1 is temporarily stopped in the same manner as when the switch 13'V is closed. will be stopped. The RS flip-flop 4 is set by the output of the AND gate δ, and its output becomes rHJK, and one input of the AND gate becomes rHJ. When the push button 16 is released with rHJ being input to the above-mentioned ant game) 26 as described above, the switch 17 returns to the solid line side, and the differential pulse via the differential circuit 21 is transmitted to the OR gate 4, the AND gate 5, and the OR gate 27. The tape 1 is inputted to the playback terminal of the control circuit 9, and the tape 1 is run at a constant speed and enters a forward-returning state. Further, the output of the AND gate is input to the delay circuit 32 and the RS flip-flop 2qK, and is reset.

In this way, the words played during a pause period, including while the tape is being rewound, can be read by pressing button 1.
By choosing the time to separate by 6g, this tar period can be selected as appropriate.

In the above embodiment, when a blank portion is detected in the reproduced signal from the magnetic tape l in the rewound state, rH is sent to the differentiating circuit section.
Although the J level is to be applied, by switching the switch 36 to the dotted line side, the rHJ level can also be applied to the differentiating circuit section as soon as the tape counter indicates zero.

In this invention, by keeping the switch 41 closed, the output of the inverter 42 is set to rHJ when the voice input from the microphone 37 is stopped in the paused state described above. Then, the tape I is run at a constant speed in the same manner as when the push button 16Y is released.

In the above embodiment, the switch 17. which is linked by the push button 16.
18 to be operated, but these switches 17
．． 18, a single switch 43'Jk may be used as partially shown in FIG. In this figure, the shrine is an inverter, and a and b are terminals corresponding to the outputs of switches 17 and 18, respectively.

Further, in the above embodiment, the continuation detection means, gate means, etc. are constituted by logic circuits, but they may be replaced by a microcomputer.

FIG. 4 shows hardware when a microcomputer is used, and the same reference numerals as in FIG. 2 or 3 indicate the same components. The shrine is a well-known microcomputer with a CPU of 45. R.O.
It is composed of a memory 47 including M46, etc., and the switch 4
3, an all-white area detection signal via the switch 36χ, a signal indicating that the sound from the microphone 37 has disappeared when the switch 41 is closed, etc. are sent to the well-known input boat 48 valves. is entered as
Output data based on this input data is obtained by a program stored in the ROM 46 of the memory 47,
This is connected to the control circuit 9 via the output boat 49.
is supplied to the play terminal, rewind terminal, and pause terminal described above.

A flowchart of a program executed to control the microcomputer 44 and related operations is shown in FIG. ■ to ■ in the figure indicate each step of the flowchart. When this program starts (step ■)j, it is asked in step ■ whether or not the push button 16 is pressed, that is, whether the switch 43 is turned on. If it is pressed, rHJ is input to the rewind terminal of the control circuit 9, and the tape 1 is rewound (step 2). 00
When a repeat instruction signal, that is, an all-white area detection signal or a counter O detection signal, is obtained during rewinding (step ■),
At this point, a question is asked as to whether or not the push button 16 is pressed (step 2). When the push button 16 is pressed, [HJ is supplied to the playback terminal of the control circuit 9, and the tape 1 is run at a constant speed to enter the playback state (step 2). Press button 1 while playing C.
When 6 is pressed (K TARE 7'■), the state is set to h anti-rewind step (■).

In step (2) above, if the push button 16 is not pressed, the temporary stop terminal 14 of the control path 9 becomes "I", and the tape I is temporarily stopped (step 1).

If the push button 16 is no longer pressed during this pause (step ■), the reproduction operation of step ■ begins. As long as the push button 16 is pressed in step (3) above.

In step (2), it is asked whether or not the sound from the microphone 37 has disappeared.If the sound has disappeared, the process moves to step (2) to enter the playback state, and if not, the paused state is maintained.

In the embodiment shown in Fig. 2 above, the movement switches 17 and 18 are operated by the push button 16, but instead of these switches, an independent switch function 51 may be used as shown in Fig. 6. . In FIG. 6, the same reference numerals as in FIG. 2 indicate the same elements. The device is a newly added AND gate, and (9) is an inverter.

In the configuration shown in FIG. 6, when the switch 50 is set to the red side and the switch 51'lt is switched to the broken line side, the rewind terminal of the control circuit 9 is connected to the rewind terminal of the control circuit 9 via the AND gate 23Y.
A differential pulse is supplied, and the tape 1 is rewound. After C, the output of the RS flip 70 is rLJ, so the above differential pulse can pass through the AND gate 2.3j1, but the differential pulse via the OR gate 28 cannot pass through the AND gate 26. When the white part of the write/send signal or O of the counter 35 is detected by the above-mentioned rewinding, the differential pulse from the differentiator circuit is applied to the reproducing terminal of the control circuit 9 via the AND gate 24 and the OR gate 27. , enters the playback state. In this case, since the switch is on the solid line side, the differential pulse from the image division N20 is
It is possible to pass through 4, but it is not possible to pass through AND gate 25.

Next, switch the switch 50 to the dashed line side, and in this state switch 51Y to the dashed line side, the differential pulse from the differential circuit 19 is applied to the control circuit 9, and the tape 1 is rewound in the same way as above. It is. During this unwinding, if a differential pulse is obtained from the differential circuit rib as described above,
This is applied to the pause terminal of the control circuit @9 through the AND gate 5, and the tape 1 is placed in a pause state. The output of the 8S flip-flop 4 becomes rHJK due to the output of the AND gate δ. In this state, switch 51 again
is switched to the dashed line side, or when the sound from the microphone 37 disappears (when the switch 41 is on), the differential pulse from the differential circuit 1f'j19 or ρ passes through the AND gate 26 via the OR gate 28, and the OR gate 27
The signal is then applied to the playback terminal of the control circuit 9, and the tape 1 enters the playback state.

FIG. 7 is a flowchart showing how the operation shown in FIG. 6 is performed by the apparatus shown in FIG. However, in place of the switch 43, a switch t equivalent to the switch 51 is used. What is different in FIG. 7 from FIG. 4 is that in steps ①, ②, and ②, instead of asking whether the push button 16 is pressed, it is asked whether the switch 510 is on or not. is easy to understand.

As described above, this invention detects when the sound from the microphone disappears and puts the paused tape into the playback state, so that the rear axis time during repeated playback is automatically set to an appropriate time. By applying this to the LL device, the device becomes easy to use.
