The present invention relates to a double deck sleep learning circuit that complements the function of a sleep learner composed of a single deck.

The conventional sleep learning circuit composed of a single deck is not only difficult to operate the reservation time setting circuit, but also difficult to record the learned contents during sleep, and various problems arise in practical use due to the lack of the sleep learning tape.

In view of the above, the present invention allows the dubbing of sleep learning materials using a double deck equipped with an automatic repeating head, and the reservation of radio broadcasting and the continuous playback of double decks. At the same time, to provide a double-deck sleep learning circuit that can be set simply when setting the reservation time and the sleep time. After the power circuit is connected and configured, the output of the automatic repeat setting unit is output to the function switching switch of the regeneration circuit.

This will be described in detail with reference to the accompanying drawings.

According to the present invention, a signal amplified by the power amplifier 2 through the coupling capacitors C _{1 to} C ₆ and the diodes D ₁ and D ₂ is output to the left and right speakers SP _1. After configuring the output circuit 10 to be output to the (SP ₂ ) and the mode switch (MS ₁ ) (MS ₂ ) to the automatic repeating head (AH ₁ -AH ₄ ) to configure the automatic repeating setting unit 20 In the reproducing circuit 15 composed of the reproducing amplifier 3 and the function switching switches FS _{1 to} FS ₅ , the audio signal output of the reproducing amplifier 3 is output through the diodes D ₃ and D ₄ . The audio signal output of the power amplifier 3 is output to the power amplifier 2 of the output circuit 10, and the outputs of the left and right heads H ₁ and H ₂ are recorded and played back switching switches (S ₁ -S). ₈ ) and the reproducing and recording circuit 25 configured to be output from the diodes D ₅ and D ₆ to the output circuit 10 through the reproducing and recording amplifier 4. The resistors R ₅ and R ₆ and a capacitor (C ₁₀₎ (C ₁₁₎ is a filter bias ball Part 6 which is configured to supply a bias power for recording.

At this time, the function switch (FS _1- FS ₆ ) is interlocked to select the operation of the radio and deck, and the mode switch (MS _1- MS ₄ ) is also interlocked with the normal state, reservation state and sleep learning state. The playback and recording switches (S ₁ -S ₈ ) are also linked to each other.

And the time setting unit 30 has set the switch (CW -CW _{1 6),} but is configured as a timer integrated devices 5 of the known associated side of the setting switch (CW ₁₎ (CW ₂₎ is a diode (D ₁₁₎ (D ₁₂ ) It is configured to be connected to the setting switch (CW ₃ -CW ₅ ) through. At this time, the setting switch (CW ₁ -CW ₆ ) is a switch that is "on" when pressed. The power source B _{1 is} connected to the radio circuit 1 and the power by the transistor Q ₁ , Q ₂ , the mode switch MS ₃ , and the function switching switch FS ₆ driven by the output of the timer integrated device 5. The power supply unit 35 is configured to be applied to the amplifier 2 and the reproduction amplifier 3 and the reproduction and recording amplifier 4, and the power supply B ₁ is a constant voltage output transistor in which a capacitor C ₁ and a diode D are connected ( It is configured to be charged to the power source B ₂ through Q ₃ ) and applied to the timer integrated device 5 at the same time.

That is, since the power source B ₂ is normally charged through the transistor Q ₃ and supplied to the timer integrated device 5 when the power source B ₁ is cut off, the driving of the timer integrated device 5 is driven by the main power source B ₁ . It is to be able to continue regardless of blocking. In addition, the conventional double deck drive unit (M ₁ ) (M ₂ ), diode (D ₁₅ ) (D ₁₆ ), and the double switch driver (40) consisting of the switch (LS ₁ ) (LS ₂ ) It is.

Here, the switch (LS ₁ ) (LS ₂ ) is connected by the recording button and the playback butter of the double deck, and performs the recording function when the recording and playback switches (S ₁ -S ₈ ) are connected to the recording contact (R). When connected to the playback contact point P, it is configured to perform the playback operation. The function switch (FS _{1 to} FS ₆ ) for switching the functions of the radio and the tape performs the tape drive only when connected to the tape contact point T. When connected to the remaining radio contacts, the switch is configured to perform the function of the radio. When the mode switch (MS _1- MS ₂ ) is connected to the sleep contact terminal (S), the sleep learning drive is performed and the reserved contact terminal ( When it is connected to R), time setting is performed, and when it is connected to the normal terminal (N), it is a switch which drives a normal double deck.

In the present invention configured as described above, the power supply of the time setting unit 30 and its operation will be described.

The power source B ₁ is charged through the common terminal N of the mode switch MS ₃ and then charged to the power source B ₂ through the transistor Q ₃ which supplies a constant voltage by the capacitor C and the diode D. At the same time, it is supplied to the power terminal of the timer integrated device 5, and when the supply of the power B ₁ is cut off, the charged power B ₂ is applied to the timer integrated device 5 so that the timer integrated device 5 is supplied. Will continue to proceed. The current time is set by pressing the setting switch (CW ₆ ) and then pressing the hour, minute and second setting switch (CW ₃ ) (CW ₁ ) (CW ₅ ) and the reservation time is set by the setting switch (CW ₂ ). After pressing, press the setting switch (CW ₃ -CW ₅ ) to set the time. For sleep learning time, press the setting switch (CW ₁ ) and then press the setting switch (CW ₃ -CW ₅ ). Will be set.

At this time, if the diode (D ₁₁ ) (D ₁₂ ) is not configured, press the setting switch (CW ₆ ) while holding down the setting switch (CW ₂ ) to make a reservation setting, and then press the setting switch (CW ₃ -CW). ₅ ) Pressing the three setting switches to set the time by pressing the inconvenience was inconvenient.

In other words, this reservation time could be set only when the setting switch (CW ₂ ) (CW ₆ ) of each selection switch was pressed while pressing the setting switch (CW ₃ -CW ₅ ) to set the hour, minute, and second. . Therefore, in the present invention, by connecting the diode (D ₁₁ ) (D ₁₂ ) by pressing only the setting switch (CW ₂ ), the reservation time can be set without pressing the setting switch (CW ₆ ). In 5), when the reserved time comes, the high level is output to the base of the transistor Q ₂ .

In addition, the double deck drive unit 40 has a double deck as the main and auxiliary motors M ₁ and M ₂ are driven in accordance with the operation of the leaf switch LS ₁ and LS ₂ and the mode switch MS ₄ . The driving of is to be controlled. Looking at the radio selection process in this invention as follows. First, when the function switching switch FS ₆ of the power supply unit 35 is connected to the radio terminal as shown in the figure, and the mode switch MS ₃ is connected to the normal terminal N, the power supply B of the power supply unit 35 ₁ ) through the normal terminal (N) of the mouwood switch (MS ₃ ) and the functional switching switch (FS ₆ ) connected to the radio terminal as shown in the drawing, and then to the radio circuit (1) and the power amplifier (2). When applied, the common radio circuit 1 is operated to output a broadcast signal through the power amplifier 2.

In addition, when the mode switch MS ₃ is connected to the reserved terminal R and the function switching switch FS ₆ is connected to the radio terminal as shown in the drawing, the radio circuit 1 is connected by the timer output of the timer integrated device 5. The power source B ₁ is applied to the power amplifier 2.

I.e., the timer integrated device 5 a when it is time to output a high level to the base of the transistor (Q ₂₎ transistors (Q ₂₎ the power by driving the (Q ₁₎ (B ₁₎ and the transistor (Q ₁₎ reserve Through the reserved terminal R of the mode switch MS ₃ and then to the radio circuit 1 and the power amplifier 2 through the function switching switch FS ₆ , the normal radio circuit 1 is reserved. It will work when the time comes. At this time, the function switching switch (FS ₆ ) is connected to other function switching switches when the radio is connected to the radio terminal as shown in the figure. In this way, when the function switch (FS ₆ ) is switched to the radio terminal as shown in the drawing, and the mode switch (MS ₃ ) is connected to the normal terminal (N), the power supply (B ₁ ) is supplied to the radio circuit (1) and the ordinary radio When the mode switch MS _{3 is} connected to the reserved terminal R, the transistor Q ₁ and Q ₂ are driven when the scheduled time of the timer integrated device 5 reaches the radio circuit 1. Power is supplied to the power amplifier 2 through the coupling capacitors C ₁ -C ₆ and diodes D ₁ (D ₂ ). The left and right speakers SP ₁ and SP ₂ are output. When the radio and the deck are driven at the time of reservation, the transistor Q ₁ and Q ₂ are driven at a high level voltage at which the reserved time is output from the timer integrated device 5, so that the radio circuit 1 and the reproduction amplifier 3 By supplying the power B ₁ to the reproduction and recording amplifier 4, the radio and the deck can be driven.

That is, when the scheduled time comes, the power source B ₁ of the power supply unit 35 is applied to the radio circuit 1, the power amplifier 2, the reproduction amplifier 3, the reproduction and recording amplifier 4, and the radio and the deck are driven. Will be.

Therefore, if the radio is reserved, the radio circuit 1 operates and outputs the broadcast signal through the power amplifier 2, and if the deck is reserved, the reproduction amplifier 3 or the reproduction and recording amplifier 4 operates to double. The signal regenerated by the selected head AH ₁ -AH ₄ (H ₁ ) (H ₂ ) by driving the conventional double-deck driver 40 for driving the deck after the power through the diode D ₃ (D ₄ ) It is output through the amplifier (2).

That is, if a deck having an auto repeat function is selected by driving the play amplifier 3 or the play and record amplifier 4 and the normal double deck drive unit 40 at the scheduled time, the auto repeat red (AH ₁ -AH ₄ ) is selected. The automatic repetitive playback output of the head is output through the power amplifier (2) and then through the power amplifier (2). If you select a deck with normal recording and playback functions, the output of the head (H ₁ ) (H ₂ ) is the playback and recording amplifier. After (4) is output through the power amplifier (2).

In this way, the radio is driven by applying the power B ₁ to the radio circuit 1 at the reserved time, and the driving of the deck is a weak time when the known double deck drive unit 40 and the reproduction amplifier 3 ) And the head of the deck with the auto-repeat function (AH ₁ -AH ₄ ) already selected by the user in the usual way (AH _{1 to} AH ₄ ) or by the recording and playback function (H _1). (H ₂ ) is operated to output a voice signal. At this time, only the head AH ₃ (AH ₄ ) of the automatic beat-up setting unit 20 is operated to play only two tracks as in normal playback. In other words, by using the head (AH ₃ ) (AH ₄ ) (H ₁ ) (H ₂ ) to perform the respective deck playback and recording and continuous operation of the double deck according to the drive of the double deck drive unit 40. It is the same technical content as a normal double deck drive. However, while the sleep learning is selected, the heads AH ₁ and AH ₂ are operated so that the heads AH _{1 to} AH ₄ are all operated to reproduce the learning contents and the sleep music recorded on the sleep learning tape.

Therefore, the present invention is designed to solve the inconvenience caused by the lack of the sleep learning tape, so that the user can make the sleep learning tape on their own. By outputting through 2) and at the same time recording through the head (H ₁ ) (H ₂ ) by recording the learning content in the user's favorite sleep music to make a sleep learning tape. And the process is reproduced by the head (H ₁ ) (H ₂ ) is as follows, for this purpose, the playback and recording switch (S ₁ -S ₈ ) should be connected to the playback terminal (P).

When the head H ₁ (H ₂ ) is selected by the deck driving of the double deck drive unit 40, the audio signal picked up from the head H ₁ (H ₂ ) is switched to the reproduction terminal P (shown in the drawing). the bar equals) playback and recording been switch (S _1- S ₄₎ through the playback and recording amplifier (to be applied to 4) and an audio signal amplified by the playback and recording amplifier 4 is playback and recording switch (S _5- S ₆ ) and through the diode (D ₅ ) (D ₆ ) and then applied to the power amplifier (2) is output through the speaker (SP ₁ ) (SP ₂ ). The reproducing operation by the heads H ₁ and H ₂ is a general reproducing operation or a continuous reproduction operation of the double deck is output through the same signal processing. On the other hand, look at the process that is recorded by the head (H ₁ ) (H ₂ ) as follows.

Before looking into the recording process for producing the sleep learning tape, the sleep music must be output from the playback amplifier 3 and the learning contents must be output from the radio circuit 1 or vice versa. do.

In other words, the radio circuit 1 and the reproduction amplifier 3 must be operated in order to make a sleep learning tape by recording with the head H ₁ and H ₂ . The audio signal of the reproduction amplifier 3 and the radio circuit 1 is recorded through the head H ₁ and H ₂ as follows.

At this time, the function switching switch (FS _1- FS ₆ ) is connected to the radio terminal (position shown in the figure) and the playback and recording switch (S ₁ -S ₈ ) should be connected to the recording terminal (R).

First, the sleep music outputted through the reproduction amplifier 3 is applied to the reproduction and recording amplifier 4 through the function switching switch FS ₄ and the reproduction and recording switch S ₂ , and the radio circuit 1 is applied. The learning content is output through the function switch (FS ₃ ) and the playback and recording switch (S ₄ ) and then applied to the playback and recording amplifier (4).

The sleep music and learning content applied to the reproduction and recording amplifier 4 are applied to the power amplifier 2 through the diode D ₅ and D ₆ through the reproduction and recording switch S ₅ and S ₆ . At the same time as the output to the speaker (SP ₁ ) (SP ₂ ) is applied to the head (H ₁ ) (H ₂ ) through the filter resistor (R ₅ ) (R ₆ ) and condenser (C ₁₀ ) (C ₁₁ ), respectively. . Therefore, in the head (H ₁ ) (H ₂ ) to which the bias of the bias supply unit 6 is supplied by switching the recording terminal (R) of the reproduction and recording switch (S ₁ ) (S ₃ ), recording of the sleep music and the learning content applied thereto are recorded. By doing so, you can complete the sleep learning tape. At this time, even if the sleep music is output from the radio circuit 1 and the learning contents are output from the reproduction amplifier 3, the result is the same.

The reproduction operation as described above can be driven by the user in general, or can be recorded at a time reserved by the output of the timer integrated device 5.

On the other hand, the driving of the sleep learning tape during sleep learning is repeatedly performed by the four-track automatic repeat head AH ₁ -AH ₄ , and the sleep learning music and its contents are amplified through the playback amplifier 3, and then the power amplifier 2 is turned on. By outputting through it, a predetermined sleep learning operation can be performed.

That is, the reproduction of the sleep learning tape is performed by the output of the reproduction amplifier 3 driven by the heads AH _{1 to} AH ₄ , and the recording operation for making the sleep learning tape is performed through the head H ₁ and H ₂ . Will be done.

As described above, the present invention allows the sleep learner to configure a double deck to perform general sleep learning, and at the same time, to record the sleep learning contents so that the sleep learning tape can be produced by itself. It is possible to provide a simple double-deck sleep learning circuit that can be simplified.
