Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape recorder, and particularly to a tape recorder in which two tapes can be set. As this type of tape recorder, the one shown in FIG. 1 has been used conventionally.

The tape recorder shown in Fig. 1 is a cassette type, with two
The tape drive devices IQA and IOB have two tape drive devices 10A and IOB, each of which has a cassette 12 set therein.
A and 12B can be run respectively.

In addition, this cassette Teso recorder has a tape drive device 10.
Recording head 1 for cassette 12A set in A
4, a recording amplifier 16 for exciting the recording head 14, a reproduction head 18 for the cassette 12B set in the tape drive device 10B, and a reproduction amplifier 20 for amplifying the detection signal of the reproduction head 18. Recording power 100
is supplied to the recording amplifier 16 via the variable resistor 22, and the playback output of the playback amplifier 201Z) is taken out to the outside via the changeover switch 24 on the one hand. On the other hand, the signal is supplied to the recording amplifier 16 via a changeover switch 24 and a variable resistor 22.

Figure 1: The conventional device consists of the above configuration, so the recording manpower is 1.
00 is supplied to the recording head 14 via the variable resistor 22 and the recording amplifier 1G, and is recorded by the recording head 14 on the tape of the cassette 12A driven by the tape drive device 10A.

Further, when the tape drive device 10BK Eli cassette set 12 is driven, the signal obtained by the playback head 18 is outputted from the playback amplifier 20 as the playback output 102, and the switch 24
The signal is further supplied to the cassette 12A via the V resistor 22, the recording amplifier 16, and the playback head 18.

In this way, this tape recorder can record 12 people on a cassette, play back the cassette 12B, and can also dub the contents of the cassette 12B onto the cassette 12A.

However, in the conventional device V mentioned above, when two cassettes with the same content are to be prepared, the recording system is only one.
Since only the system is provided, when recording a record, it is necessary to play it back twice, and when recording the entire signal from a tuner, etc., it is necessary to perform dubbing after recording, which takes time. A problem has arisen in that it requires a lot of effort and is very inconvenient to use the tape recorder.

The present invention has been made in view of the above-mentioned conventional problems,
The purpose is to provide a tape recorder that can easily accommodate two cassettes with the same content.
Melt.

In order to achieve the above object, the present invention has two systems of a recording amplifier and a tape drive device, and selects the recording input of its own system and the recording input of another system on the input side of at least one of the recording amplifiers. All features include a recording selection switch.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a tape recorder according to the present invention will be described below based on the drawings.

FIG. 2 shows a preferred embodiment of the tape 1/coder according to the present invention, and the tape recorder of this embodiment is of a cassette type, with a cassette 12A.

12B is a tape drive device 10A that drives each of them;
It is set to IOH.

In this embodiment, recording heads 14A and 14B are provided for each cassette 12A and 12B set in ten tape drives and 10B, and these are excited by recording amplifiers 16A and 16B, respectively.

In addition, variable resistors 2'2A and 22B are provided in front of the recording amplifiers 16A and 16B, respectively, and recording power A and B are supplied to the variable resistors 22A and 22B from recording terminals 26A and 26B, respectively. There is.

Further, a recording changeover switch 28 connected to the recording input terminals 26A and 26B is provided, and the recording changeover switch 728 has a recording power of 100 A.

1008 can be selected and output to the recording amplifier 16B via the variable resistor 22Bfc.

A preferred embodiment of the tape recorder according to the present invention has the above configuration, and its operation will be explained below.

When recording to cassette 12A, use cassette 12A.
A is driven by ten tape drives, and a recording input 100A is applied to a recording amplifier 16A via a variable resistor 22A to amplify it, and the recording head 14A'e is excited.

In addition, when recording from the cassette 12B, the recording selector switch 28 is moved to the recording input terminal 26B side.
00Bfc is supplied to the recording amplifier 16B via the variable resistor 22B, and the output of the recording head 14B'i is excited. In addition, at this time, the tape drive device 10B drives the cassette) 12
B is driven.

When simultaneously recording the same content on the cassettes 12A and 12B, the recording selector switch 28 is turned to the recording input terminal 26A side, and the tape drive device 10A and IOB are used to record the same content on the cassette 12A.

While driving 12B'i, recording heads 14A and 14B are excited by recording amplifiers 16A and 16B in response to recording input 100A.

In addition, when recording different recording power 100A, 100B to the cassettes 12A, 12B, respectively, turn the recording changeover switch 28 to the recording input terminal 26B side, and turn on the recording amplifier 16A while starting the tape drive devices 10A, 10Bf, respectively. , 16B respectively excite the recording heads 14A, 14B in accordance with the recording human power 100A, 100B.

As explained above, according to the present invention, two recording systems are provided and the same recording input terminal can be connected to both systems using the recording selection switch, so that tapes having the same content can be adjusted simultaneously. Therefore, it does not require a lot of time and effort4) for adjustment as in the past.
Furthermore, there is no deterioration in sound quality caused by dubbing.

Furthermore, according to the present invention, a recording selection switch is provided on the input side of at least one of the recording amplifiers to select between the recording input of its own system and the input of another system, so that the It is also possible to record different contents separately on the tape.
