It is something.

[Conventional technology and its problems]

Generally, amplifiers are connected to multiple devices such as tape recorders, tuners, record players, etc., so they are equipped with a source select switch that switches the source signal, and a recording select switch that switches the recording output signal. It is now possible to select the recording output signal to the tape recorder connected to the amplifier, in addition to the source being connected to the amplifier. Therefore, the operator can listen to the source while simultaneously recording signals from equipment other than the source, and if the amplifier can connect two tape recorders, dubbing between the two tape recorders is also possible. I am now able to do it.

Figure 2 shows an example of the conventional amplifier mentioned above. In the figure, PO is the input terminal for connecting each device to the amplifier, and T1 and T2 are the input terminals for connecting two tape recorders 1 and 2, respectively.

On the other hand, S ₁ is a source select switch that selects the source signal and supplies it to the buffer amplifier BA, and S ₂

_S3 is a so-called tape monitor switch for selectively connecting the input side of the buffer amplifier BA to the tape recorder 1, tape recorder 2, and source.

Next, the connection relationship between each terminal and each switch is shown.

Then, to explain the operation according to the above conventional example,
When the movable contact S _3-0 of the tape monitor switch S ₃ is switched to the source side, that is, the fixed contact S _3-2 , the input side of the buffer amplifier BA is connected to the movable contact S _1-0 of the source select switch S ₁ . Therefore, by switching the source select switch _S1 , a record player, tuner, external input, etc. can be selected. In addition, when the movable contact S _3-0 of the tape monitor switch S ₃ is switched to the fixed contacts S _3-1 and S _3-3 , the playback input terminals PBIN1 and PBIN2 of the tape recorder terminals T1 and T2 are switched to the fixed contacts S 3-1 and S 3-3, respectively.
is connected to buffer amplifier BA, and the reproduction signals of tape recorders 1 and 2 can be heard.

On the other hand, if we look at the recording output select switch S ₂ , the movable contacts S _21-0 of the switch S ₂₁ and S ₂₂ ,
When S _22-0 is switched to the fixed contacts S _21-1 and S _22-1 , the playback input terminal PBIN1 of the tape recorder terminal T1 is connected to the recording output terminal RECOUT2 of the tape recorder terminal T2, and the tape recorder 1
Dubbing can be performed from the source to the tape recorder ₂ regardless of the source select switch S1.
In addition, the movable contacts S _21-0 and S _22-0 are fixed contacts S _21-2 ,
When switched to S _22-2 , dubbing can be performed from tape recorder 2 to tape recorder 1 in the same way.

In addition, the movable contacts S _21-0 and S _22-0 are fixed contacts S _21-3 and
When switched to S _22-3 , record player input terminal PHONO is used, fixed contact G _21-4 , and when switched to S _22-4 , tuner input terminal TUNER is used.
However, when the fixed contacts S _21-5 and S _22-5 are further switched, the external input terminal AUX becomes the recording output terminal RECOUT of the tape recorder terminals T1 and T2, respectively.
1. Connected to RECOUT2 and can record the contents of each program source.

However, the prior art example described above has very serious drawbacks.

When recording signals from a record player, tuner, external input, etc. connected to the amplifier, in other words, replace the movable contacts S _21-0 and S _22-0 of the recording output select switches S ₂₁ and S ₂₂ with the fixed contacts S _21-3, respectively. ~S _21-5 ,
When switching from S _22-3 to _{S 22-5} , the recording output terminal RECOUT1 of tape recorder terminals T1 and T2,
The exact same signal is always supplied to RECOUT2. Therefore, tape recorders 1 and 2 also have
Although it is always possible to simultaneously record a single program source selected with the recording output select switch on two tape recorders, it is not possible to simultaneously record signals from different program sources, such as a record player and a tuner, on each tape recorder. Unable to do so, the operator installed two tape recorders in the amplifier.
Even though the recorder is connected, only one recording source can be selected at a time, which is an extremely inefficient operation.

Also, in recent years, so-called double cassette tape recorders, which have two tape transports mounted on one main unit, have rapidly become popular, so considering the current situation, it is becoming standard to equip an amplifier with two tape recorders. However, the inability to independently select the recording source in each tape recorder is a fatal drawback.

On the other hand, one possible solution to the above problem is to provide an independent recording output select switch _S2 for each tape recorder so that each recording source can be selected independently. For example, the circuit connection becomes complicated, and an extra large switch such as a rotary switch must be installed on the amplifier panel, which limits panel space and increases costs. It has the following problems and cannot be a solution to the problems.

[Purpose of invention]

The present invention was made to solve all of the above-mentioned problems, and its purpose is to provide an amplifier that allows two tape recorders connected to the amplifier to simultaneously record different program sources. .

[Summary of the idea]

In an amplifier that can connect two tape recorders and is equipped with a source select switch that selects a source signal and a recording output select switch that selects a recording output signal, a first recording output terminal that outputs a recording signal to one tape recorder. The second recording output terminal, which outputs the recording signal to the other tape recorder, selectively supplies each output signal of the source select switch and the recording output select switch. The present invention provides a novel amplifier which is configured to allow two tape recorders to simultaneously record separate signals from a recording output signal and a source signal.

〔Example〕

Figure 1 shows one embodiment of the present invention;
The same reference numerals are used for parts having the same configuration as those of the conventional example shown in the figure, and the explanation thereof will be omitted.

As is clear from the figure, each input/output terminal 1,
The basic configuration and operation among the source _select switch S ₁ , recording output select switch S ₂ , and tape monitor switch S ₃ are the same as shown in FIG. is added.

In other words, the source/recording output selector switch _S4 is
The movable contact _S4-0 is connected to the recording output terminal RECOUT2 of the tape recorder terminal T2, and the fixed contact
Source select switch for S _4-1 and S _4-2 respectively
S ₁ , recording output select switch S ₂₂ movable contact
Connected to S _1-0 and S _22-0 .

Therefore, if the movable contact S _4-0 is switched to the fixed contact S _4-2 , the recording output terminal RECOUT2 of the tape recorder terminal T2 receives the recording output signal selected by the recording output select switch S ₂₂ , that is, the tape recorder terminal. The same signal is supplied to the recording output terminal RECOUT1 of T1, and the connection relationship is the same as in FIG. 2.

On the other hand, when the movable contact _S4-0 of the source/recording output selector switch _S4 is switched to the fixed contact _S4-1 , the recording output terminal RECOUT2 of the tape recorder terminal T2
is connected to the movable contact _S1-0 of the source select switch _S1 , so that the source signal selected by the source select switch _S1 is supplied.

By this operation, the tape recorder 1 connected to the tape recorder terminal T1 transfers the recording source selected by the recording output select switch _S2 to the tape recorder 2 connected to the tape recorder terminal T2.
The sources selected by the source select switch _S1 can be recorded independently and simultaneously.

That is, according to the configuration of the present invention, different program sources can be simultaneously recorded on each of the two tape recorders connected to the amplifier.

Furthermore, the configuration of the present invention also has the following merits.

That is, in the conventional example shown in FIG. 2, when tape recorders 1 and 2 are recording the same signal, adjustments to the recording level, including fade-in and fade-out, must be made for each tape recorder, which requires the operator to requires the simultaneous operation of two tape recorders, which is extremely complicated and can lead to operational errors.

On the other hand, according to the configuration of the present invention, the movable contact S _4-0 of the source/recording output selection switch S ₄ is replaced with the fixed contact S _4-2.
The source signal selected by the source select switch S ₁ is first recorded by the tape recorder 2 connected to the tape recorder terminal T2, and at the same time the movable contacts of the recording output select switches S ₂₁ and S ₂₂
If the mode is set to dubbing from tape recorder 2 to tape recorder 1 by switching S _21-0 and S _22-0 to fixed contacts S _21-2 and S _22-2 , respectively, the current recording on tape recorder 2 The contents are sent to the tape recorder terminal T via the tape recorder 2.
2 is supplied from the playback input terminal PBI2 to the recording output terminal RECOUT1 of the tape recorder terminal T1,
The tape recorder 1 can also record the same content as the tape recorder 2. At this time, tape recorder 2 becomes the master side of tape recorder 1, so if you adjust the recording level of tape recorder 1 first, all adjustments to the recording level, etc., including fade-in and fade-out, will be made on tape recorder 2. This greatly improves operability and prevents erroneous operations.

[Effect of idea]

As described above, according to the recording output switching device for an amplifier of the present invention, two tape recorders can be connected, and it is equipped with a source select switch for selecting a source signal and a recording output select switch for selecting a recording output signal. The first recording output terminal that outputs the recording signal to one tape recorder is supplied with the output signal of the recording output select switch as is, and the second recording output terminal that outputs the recording signal to the other tape recorder is supplied with the source. Since each output signal of the select switch and recording output select switch can be selectively supplied, two tape recorders can simultaneously record different program sources from the recording output signal and the source signal. In addition to greatly improving operability, recording time can be greatly reduced when recording multiple program sources.

Also, if one tape recorder records the program source selected by the source select switch, and at the same time the recording output select switch supplies the output of said one tape recorder as the recording output to the other tape recorder, the master Since the recording level of the slave tape recorder can be adjusted simultaneously by the tape recorder on the side, it is possible to fade in, fade out, and adjust the recording level of the two tape recorders just by operating one tape recorder. This is effective in reducing the burden on the operator and preventing erroneous operations.

Looking at the configuration, even though two tape recorders can record different program sources at the same time, the configuration is simpler than the conventional example, with only a new source/recording output selector switch installed. It does not require complicated circuit connections or expensive large parts such as rotary switches, and has great effects in terms of space, panel design, and cost.
