[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape recorder.

[0002]

2. Description of the Related Art Generally, when music is recorded on a CD or a cassette tape, a silent interval of about 3 to 5 seconds is formed between music pieces. So, some tape recorders
A function to detect the silent section and quickly find the beginning of the song,
That is, a function called AMS is provided.

FIG. 7 shows an example of a signal system of a cassette tape recorder having the AMS function.
Left and right channel audio signal systems 10L, 10
R, detection circuit 20 for AMS, and tape running mechanism 30
And a microcomputer 40.

In this case, in the audio signal system 10L for the left channel, the reproducing head 11 reproduces the audio signal L for the left channel from the magnetic tape 9, and this signal L is reproduced equalizer circuit 12 → noise reduction circuit 13 → volume. It is supplied to the acoustic unit 16 of the left channel of the headphones through the signal line of the variable resistor 14 for adjustment → the output amplifier 15.

The right channel audio signal system 1
The same applies to 0R, and the head 11 reproduces the audio signal R of the right channel from the tape 9,
It is supplied to the sound unit 16 of the right channel of the headphones through each of the circuits 12 to 15.

Further, the detection circuit 20 for AMS is composed of an addition circuit 21, a detection circuit 22 and a waveform shaping circuit 23, and outputs a signal S23 which will be described later.

Although not shown, the tape running mechanism 30 has a capstan, a pinch roller, a motor for driving the capstan and reel, a plunger, and the like, and the lever triggers the lever and the like. The mechanical state of the tape recorder is controlled or maintained in the reproduction mode, the fast-forward mode, etc. by utilizing the rotational force of the motor.

Further, the microcomputer 40 controls the system of the tape recorder and is connected with various operation keys 41 composed of non-lock type push switches. Then, the operation key 41
Of these, for example, when the play key is pressed, the running mechanism 30 is controlled by the microcomputer 40 to set the mechanical operation mode of the tape recorder to the play mode, and the tape 9 is run at a constant speed.

Therefore, the heads 11 and 11 reproduce the audio signals L and R from the tape 9, and the signals L and R are supplied to the acoustic units 16 and 16 as described above. That is, the tape recorder is in the reproduction mode.

Further, for example, when the fast forward key or the rewind key of the operation keys 41 is pressed in the reproduction mode, the tape 9 is made to run at high speed in the fast forward direction or the rewind direction by the running mechanism 30. At this time, the tape 9 is left in contact with the heads 11, 11.

Therefore, the heads 11 and 11 output the audio signals L and R reproduced at high speed, and the signals L and R are obtained from the reproduction equalizer circuits 12 and 12. The signals L and R are supplied to the adder circuit 21. It is supplied and the addition signal S21 is taken out. Then, this signal S21 is supplied to the detection circuit 22 and, for example, as shown in FIG.
Is a DC signal (DC voltage) S22 whose level changes in accordance with the level of.

In this case, as shown in FIG. 8A, the level of the signal S22 is high when the section of the music piece of the tape 9 is being reproduced, and the level of the signal S22 is low when the silent section is being reproduced. , Or 0. Therefore, the signal S22 is supplied to the waveform shaping circuit 23 and the level V
The waveform is shaped with TH as the threshold level, and the shaping circuit 23 outputs a rectangular wave signal S that becomes “H” in the section of the music and “L” in the silent section, as shown in FIG. 8B.
23 is taken out.

Then, the signal S23 is supplied to the microcomputer 40, the signal S23 falls, and
When the trailing edge continues for a predetermined period τ, it is determined that there is a silent section between songs, and thus the traveling mechanism 30 is set to the stop mode and then to the reproduction mode.

Therefore, in the case of AMS in the fast-forwarding direction, when the tape 9 travels from the end point PA of the music to the point P1 after the period τ has elapsed, the tape 9 enters the stop mode and then the reproduction mode. Will be played normally from the beginning of the next song. Further, in the case of AMS in the rewinding direction, when the tape 9 runs to the point P6 after the period τ has elapsed from the start point PB of the music, the tape 9 enters the stop mode and then the reproduction mode. It will be played normally from the first part of the song up to.

Thus, according to the AMS function, it is possible to automatically find the beginning of a music piece. In this case, the tape 9 is used.
Can be run at high speed by fast-forwarding or rewinding to the beginning of the song, so that the song can be cueed at high speed. The AMS mechanism is widely installed in tape recorders, particularly headphone stereos.

[0016]

By the way, in an actual tape recorder, when the tape 9 is run at high speed, the tape 9 and the hub have inertia. The tape 9 does not stop immediately, but travels a little and then stops (this running of the tape 9 due to inertia is referred to as "tape flow" hereinafter).

Moreover, the size (length) of the tape flow.
Is difficult to estimate because it varies depending on the type of tape and the running position of the tape. In addition, if the running speed of the tape 9 is made higher in order to shorten the time required to find the beginning of the music by the AMS and the time required to fast forward / rewind, the tape flow becomes larger and the size thereof is estimated. It gets more difficult.

As a result, at the time of AMS, the tape 9 could not be stopped in the silent section, and if the AMS was performed in the fast-forward direction, the beginning of the song would be missing and the AMS was performed in the rewinding direction. Sometimes the end of the previous song is played.

Therefore, it is conceivable to suppress the tape flow and stop the tape 9 in the silent section by, for example, the following methods (1) to (3). That is, accurately predict the magnitude of tape flow. Provide a strong braking mechanism. A large back tension is set on the tape 9 to reduce tape flow.

However, the above method is difficult to predict as described above, and when it is attempted to be realized, the operation becomes complicated,
It takes time to finish the beginning of the song. Further, when the method is applied to a small and lightweight set such as a headphone stereo, it causes an increase in size, weight, increase in price, and decrease in reliability. Further, in the case of the method (1), the current consumption during operation increases, and the headphone stereo powered by the battery cannot be used for a long time.

The present invention is intended to solve the above problems.

[0022]

Therefore, in the present invention, a reproducing head for reproducing an audio signal from a magnetic tape, a detection circuit for detecting a silent section of the magnetic tape from the audio signal, and an audio signal for the audio signal are provided. A circuit for muting, a detection means for detecting the running amount of the magnetic tape, and a control circuit for controlling the running of the magnetic tape, and when a predetermined key operation is performed,
The control circuit controls the magnetic tape to run in the fast-forward direction at a speed higher than that during normal reproduction, while the muting is turned on, and in the high-speed running mode, the detection circuit causes the silent section to operate. When detected, controlling the stop mode by the control circuit, the running amount of the magnetic tape until the running of the magnetic tape from the tape position when controlling the stop mode is detected by the detecting means, The control circuit controls the rewinding mode in the rewind mode according to the detection result, and after the rewinding mode is executed, the control circuit controls the stop mode to set the magnetic tape to the silent section or the tape. Stop at the start end side, and execute the playback mode from this stop position by the above control circuit. In over de is for a tape recorder which is adapted to turn off the muting from the tape position of the magnetic tape reaches a predetermined position of the silent section. Therefore, regardless of the size of the tape stream, the beginning of the music by the AMS is executed.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, left and right channel audio signal systems 10L and 10R and a detection circuit 2 are shown.
0, tape running mechanism 30, microcomputer 40
Is configured similarly to FIG.

In this case, the microcomputer 40
To control the system of this tape recorder, CP
U, a ROM in which a program is written, a RAM for a work area, an input / output port, and the like. As a part of the program, for example, A as shown in FIGS.
It has an MS routine 100. In addition, this routine 10
Details of 0 will be described later.

Further, in FIG. 2, reference numeral 31 is a supply-side reel shaft, and reference numeral 32 is a winding-side reel shaft. The reel shafts 31 and 32 have gears 33 and 34, respectively.
Are rotationally coupled to each other, and a gear 35 is provided which is rotationally driven clockwise or counterclockwise by a motor (not shown).

The gear 35 is rotatably coupled to the gear 33 when the reel shaft 31 needs a rotational force in the rewinding direction, and when the reel shaft 32 needs a rotational force in the winding direction. It is adapted to be rotationally coupled to 34. The traveling mechanism 30 is not provided with a mechanical brake, but the brake is realized by controlling the rotation of the motor.

Further, in this example, a reflecting plate 51 having reflecting portions and non-reflecting portions alternately arranged in the rotation direction is provided on one surface of the gear 33, and the reflecting plate 5 is also provided.
A photo-reflector 52 is provided so as to face 1. In this way, the signal S52 whose level changes to "L" or "H" according to the passage of the reflection portion and the non-reflection portion of the reflection plate 51 when the gear 33 rotates is extracted from the photo reflector 52.

Therefore, the signal S52 is obtained each time the reel shaft 31 rotates by a predetermined angle, so that the frequency of the signal S52 is proportional to the rotation frequency of the reel shaft 31 or the signal S52 as the tape 9 runs. The pulse of S52 will be obtained. As an example, the frequency of the signal S52 during reproduction is 1.4 Hz (at the tape start end) to 3.4 Hz (at the tape end).

Then, as shown in FIG. 1, this signal S52
Is supplied to the waveform shaping circuit 53 to be waveform shaped and then supplied to the microcomputer 40. Therefore,
The microcomputer 40 sends the tape 9 by the signal S52.
It is possible to know the running amount of the tape 9 and whether the tape 9 is running.

Further, a muting control signal S15 is supplied from the microcomputer 40 to the amplifiers 15 and 15.

According to such a configuration, the routine 100 is executed during the AMS to realize the cueing. However, to facilitate understanding, first, the tape 9 at the time of the cueing is realized.
The movement of will be described with reference to FIGS.

That is, FIG. 5 shows the operation at the time of AMS in the fast-forwarding direction, and FIG. 5A shows the signal S23 when the tape 9 continuously runs, and corresponds to FIG. 8B.

FIG. 5B shows the movement of the tape 9 when the inertia of the tape 9 is large, and FIG. 5C shows the movement of the tape 9 when the inertia of the tape 9 is small. Further, in FIGS. 5B and 5C, the solid arrow indicates the movement of the tape 9 by being driven, and the broken arrow indicates the movement of the tape 9 by the tape flow.

(A) Until the tape 9 first stops (Fig. 5)
(A part common to B and FIG. 5C) At the time of AMS in the fast-forward direction, the tape 9 is driven by the fast-forward as shown by an arrow 1 in FIGS. 5B and C, but when the tape position reaches the point P1, the tape 9 runs. Mechanism 30
Is in stop mode.

Therefore, as indicated by the arrow 2, the tape 9 runs from the point P1 by the tape flow and stops at the point P2. In this case, when the tape 9 has a large inertia and the tape flow is large, the point P2 is located far away from the point P1 as shown in FIG. 5B. Further, when the inertia of the tape 9 is small and the tape flow is small, the point P2 is not so far from the point P1 as shown in FIG. 5C.

Further, during the tape flow indicated by the arrow 2, the number of pulses of the signal S52 is counted and the magnitude of the tape flow is measured. The number of pulses at this time is N2.

When the tape 9 stops at the point P2,
The number of pulses N2 is the preset value α
(For example, α = 5), and as a result of this comparison, subsequent processing is divided into the next processing (B) and processing (C).

(B) In the case of N2> α (in the case of FIG. 5B) In the case of N2> α, the traveling mechanism 30 is set to the rewinding mode, and the tape 9 is moved to the point P2 as shown by the arrow 3 in FIG. 5B. Is rewound from. And during this rewind,
The number of pulses of the signal S52 is counted, and the counted number is (N
2-α), at the point P3 at this time, the traveling mechanism 3
0 is the stop mode.

Then, as a result of the stop mode being set at the point P3, as shown by the arrow 4A or 4B, the tape 9
Runs from point P3 by inertia and stops at point P4A on the tape start side of point PA or at point P4B in the silent section.

Then, when the tape 9 is stopped at the point P4A or P4B, the running mechanism 30 is subsequently set to the reproduction mode. Therefore, thereafter, as shown by the arrow 5A or 5B, the running of the tape 9 from the point P4A or P4B becomes the reproduction mode.

In addition to the above tape control, the audio signal system 10L, 1L
In 0R, muting is turned on. And arrow 4
During the tape flow indicated by A and 4B, the magnitude of the tape flow is measured using the signal S52 (this measured value is N4), and when the tape 9 stops at the point P4A or P4B, the value N4. Is used to determine whether the stop point is the point P4A or the point P4B.

That is, since the distance between the points P1 and P2 = N2, the distance between the points P3 and P2 = N2-α, the distance between the points P4A or P4B and the point P1 = N4-α. Therefore, when P = N4−α, P> 0 at the point P4A and P ≦ 0 at the point P4B. When the vehicle travels from the point P4A in the reproduction direction by the value P, the point P1 is reached.

Thus, whether the stop point is the point P4A or the point P4B
Is determined, and when the result of this determination is point P4A, this point P4A is on the tape start side rather than the silent section.
As indicated by arrow 5A, muting remains on even when tape 9 begins to run in playback mode from point P4A.

At this time, the pulse of the signal S52 is counted from the point P4A, and when the count value reaches the value P, the tape position is the point P1, so the muting is turned off. Therefore, the music from the point PB is normally reproduced, and the end portion of the previous music is not heard.

As a result of the determination as to whether the stop point is the point P4A or the point P4B, when the point P4B, the point P4B is included in the silent section, so that the tape 9 is pointed as shown by the arrow 5B. Muting is turned off when the vehicle starts running in playback mode from P4A. Therefore, the music piece from the point PB is reproduced normally, and the start portion of the music piece is not missing.

Thus, in the case of FIG. 5B, the music is correctly reproduced from the beginning, and at this time, the end portion of the previous music is not heard as a reproduced sound.

(C) In the case of N2≤α (in the case of FIG. 5C) Also in the case of N2≤α, the traveling mechanism 30 is set to the rewind mode from the point P2, but as shown by the arrow 3 in FIG. 5C,
The tape 9 is rewound by one pulse of the signal S52, and the running mechanism 30 is set to the stop mode at the point P3 corresponding to the one pulse.

Then, as a result of the stop mode being set at the point P3, as shown by the arrow 4A or 4B, the tape 9
Runs from point P3 by inertia, and stops at point P4A on the tape start side of the silent section or at point P4B in the silent section.

As described above, the point P4B is S23 = regardless of whether it is the case of FIG. 5B or the case of FIG. 5C.
The value α is set so as to be located in the “L” section. That is, the value (N2- [alpha]) is the minimum value for which the stop point P4B is located closer to the tape start end side than the point PB when the rewinding indicated by the arrow 3 is performed.

Then, thereafter, the same processing as in the case of FIG. 5B, that is, the same processing as in the processing (B) is executed.

Therefore, also in the case of FIG. 5C, the music is correctly reproduced from the beginning, and at this time, the end portion of the previous music is not heard as a reproduced sound.

On the other hand, FIG. 6 shows the operation at the time of AMS in the rewinding direction, and FIG. 6A shows the signal S23 when the tape 9 continuously runs, and corresponds to FIG. 8B.

At the time of AMS in the rewinding direction, the tape 9 is driven by rewinding as shown by an arrow 6 in FIG. 6B, but when the tape position reaches the point P6, the running mechanism 30 is in the stop mode. It is said that

Therefore, as indicated by the arrow 7, the tape 9 runs from the point P6 by the tape flow and stops at the point P7. Then, during the tape flow period shown by the arrow 7, the number of pulses of the signal S52 is counted and the magnitude of the tape flow is measured. The measured value at this time is N7.

When the tape 9 stops at the point P7,
The traveling mechanism 30 is set to the fast-forward mode, and the tape 9 is fast-forwarded from the point P7 as indicated by the arrow 8. Then, during the fast feed indicated by the arrow 8, when the number of pulses of the signal S52 is counted and the count value becomes equal to the value N7, that is, when the vehicle travels to the point P6, the traveling mechanism 30 is set to the stop mode, and thereafter, the fast feed direction. The operation after arrow 2 at the time of AMS is performed. That is, the fast-forward shown by the arrow 8 corresponds to the fast-forward shown by the arrow 1 in FIG. 5, and the processing after the arrow 2 in FIG.

Therefore, also in the case of AMS in the rewinding direction, the music is correctly reproduced from the beginning of the music, and at this time, the end portion of the previous music is not heard as a reproduced sound.

The above processing is realized by the CPU of the microcomputer 40 executing the routine 100.

That is, for example, in the reproduction mode,
When the fast-forward key of the operation keys 41 is pressed, the CPU processing starts from step 111 of the routine 100,
Next, in step 112, the amplifier 1 is operated by the signal S15.
Muting Nos. 5 and 15 are turned on, and subsequently, in step 113, the traveling mechanism 30 is controlled to enter the fast forward direction AMS mode. This is the arrow 1 in FIG.
Is the state of.

Next, in step 114, S23 =
It is checked whether the state of "L" continues for the period τ and whether the tape position is in the silent section. If it is not in the silent section, step 11
4 is repeated.

When the tape position is in the silent section,
The process proceeds from step 114 to step 121, and the traveling mechanism 30 is controlled to enter the stop mode. It should be noted that this stop mode is realized, for example, by stopping energization of the motor. Further, this point corresponds to the point P1 in FIG. 5, and thereafter, the tape flow indicated by the arrow 2 will occur.

Then, in step 122, the signal S
Counting of 52 pulses is started, and tape 9 is at point P2.
Then, in step 123, counting of the number of pulses is stopped, and the counting result is set to the number of pulses N2.

Next, at step 131, the magnitude relation between the value N2 and the value α is discriminated, and when N2> α, the process proceeds from step 131 to step 132, where the value X indicated by X = N2-α It is calculated. When N2 ≤ α in step 131, the process proceeds from step 131 to step 133, and X = 1 is set.

Then, the process proceeds to step 134 following step 132 or step 133, and the traveling mechanism 30 is set to the rewinding mode indicated by the arrow 3. Then, during this rewinding, the number of pulses of the signal S52 is counted, and when the count value reaches the value X, the tape position is the point P3, so in step 141, the running mechanism 30 is set to the stop mode. This time point corresponds to the point P3, and thereafter, the tape flow of the arrow 4A or 4B will occur.

Then, in step 142, the signal S
Counting of 52 pulses is started, and tape 9 is at point P4A.
Alternatively, when the pulse number is stopped at 4B, the counting of the pulse number is stopped in step 143, and the count result is set as the pulse number N4.

Next, in step 151, the value P is calculated, and in the following step 152, the traveling mechanism 30 is set to the regeneration mode, and therefore the arrow 5A or 5B is set.
As indicated by, the tape 9 starts running at the time of reproduction from the point P4A or P4B.

Further, at this time, in step 153, the magnitude of the value P is discriminated, and when P> 0, the tape 9 starts traveling from the point P4A, and therefore the processing advances to step 154. Then, in this step 154,
When the number of pulses of the signal S52 is counted and the count value reaches the value P, the tape 9 is at the point P at this time.
Since it has reached 1, the process proceeds to step 155, the muting of the amplifiers 15 and 15 is turned off by the signal S15, and then the process proceeds to step 199 to wait for the next key input wait.

When P≤0 in step 153, the tape 9 starts running from the point P4B.
The process proceeds to step 155, and the amplifier 1 is activated by the signal S15.
Muting of Nos. 5 and 15 is turned off, and then the process proceeds to step 199.

Therefore, in the playback mode, when the fast-forward key of the operation keys 41 is pressed, when the silent section between the music up to that time and the next music is detected, the magnitude of the tape flow is detected. However, the reproduced sound can be heard from the beginning of the next song, that is, the AMS in the fast-forward direction is correctly performed.

On the other hand, for example, when the rewind key of the operation keys 41 is pressed in the reproduction mode, the processing of the CPU starts from step 161 of the routine 100, and then at step 162, the amplifier 1 is sent by the signal S15.
Muting Nos. 5 and 15 are turned on, and subsequently, at step 163, the traveling mechanism 30 is controlled to be in the AMS mode in the rewinding direction. This is the state of arrow 6 in FIG.

Next, in step 164, S23 =
It is checked whether the state of "L" continues for the period τ and whether the tape position is in the silent section. If it is not in the silent section, step 16
4 is repeated.

When the tape position is in the silent section, the process proceeds from step 164 to step 171.
The traveling mechanism 30 is controlled to enter the stop mode. In addition,
This time point corresponds to the point P6 in FIG. 6, and thereafter, the tape flow of the arrow 7 will occur.

Then, in step 172, the signal S
Counting of 52 pulses is started, and tape 9 is at point P7.
Then, in step 173, counting of the number of pulses is stopped, and the counting result is set as the number of pulses N7.

Next, at step 181, the traveling mechanism 30 is set to the fast-forward mode, and as shown by the arrow 8,
The tape 9 is fast forwarded from the point P7. Then, at this time, the number of pulses of the signal S52 is counted, and when the count value reaches the value N7, that is, when the tape 9 reaches the point P6, the traveling mechanism 30 is set to the stop mode in step 182.

Therefore, the tape 1 is stopped at the point P6, and thereafter, as indicated by the arrow 2, it travels in the tape flow. However, this tape flow is regarded as the tape flow of the arrow 2 in FIG. Proceed to 122, and then
This step 122 and subsequent steps are executed.

Therefore, in the reproduction mode, when the rewind key of the operation keys 41 is pressed, when the silent section between the previous music and the previous music is detected, the tape flow amount is large. However, you can hear the playback sound from the beginning of the song, that is, A in the rewind direction.
MS will be done correctly.

Thus, according to this tape recorder,
Although AMS can be executed, in this case, the algorithm is based on the assumption that the tape 1 runs due to inertia even if the tape flow, that is, the tape running mechanism 30 is in the stop mode. It is not necessary to stop the tape 9 in the silent section between them.

Therefore, unlike the above, it is not necessary to accurately predict the size of the tape stream, the processing is simple, and the beginning of the music can be quickly found. Also,
Since it is not necessary to install a strong brake mechanism like
Even if the tape recorder is a small and lightweight set such as a headphone stereo, it does not cause an increase in size or weight, an increase in price, or a decrease in reliability.

Furthermore, since it is not necessary to set a large back tension on the tape 9 to reduce the tape flow as described above, the current consumption during operation does not increase, and even in a headphone stereo powered by a battery, You can use your time.

[0079]

As described above, according to the present invention, the processing is simple and the beginning of the music can be quickly found. Also,
The tape recorder does not become large and heavy, and the price does not increase and the reliability does not decrease. further,
The current consumption during operation does not increase, and a tape recorder using a battery as a power source can be used for a long time.
