Description

[Detailed Description of the Invention] The present invention relates to a tape recorder (commonly known as a double cassette tape recorder) that is equipped with a plurality of cassette decks and is capable of continuously recording or playing back the cassette tapes set in each deck as well as dubbing. A changeover switch is provided to select continuous recording/playback or dubbing, so that these operations can be performed electrically and automatically, and dubbing operations can be performed simultaneously on two devices using a single pause button. It was made so that it could be done.

Conventionally, in this type of device consisting of, for example, two decks, the operation of the first deck has been linked to the second deck through a mechanical element such as a link mechanism. For example, in the case of continuous recording (replay), when the first deck auto-stops, the pause lever of the second deck is released via a link mechanism from the first deck to the second deck, and the selected recording or playback state is started. ing. Devices based on such mechanical elements have complicated interlocking elements because the two decks are assembled in separate processes, and may malfunction due to slight errors in the installation of both decks, deformation of parts, expansion or contraction of the attached casing due to temperature, etc. It has the disadvantage that it is unstable and has poor durability because it sometimes does not work or does not work, and that the cost of the mold etc. is large and expensive. Therefore, in the present invention, continuous recording (replay) or dubbing can be switched with a single changeover switch, and both decks are electrically linked together.Furthermore, when dubbing, both decks can be started by pressing the pause button on one deck, and the other deck can be started by pressing the pause button on one deck. To provide a tape recorder which can eliminate the need for setting and releasing a deck pause button.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Decks D1 and D2 have motors M1 and M that drive the magnetic tapes in the cassettes attached to both decks.
2 and mode changeover switches S2 and S4 which are operated on and off in conjunction with each recording or playback button. Further, a changeover switch S1 for selecting either dubbing or continuous recording (replay) is provided, which is connected to the motors M1, M2 and switches S2, S4. Furthermore, the one deck D1 is provided with a pause switch S3 that is linked to the pause button, and the switch S3 is connected to the motor M2 of the second deck D2, and the motor M2 of the deck D2 is controlled in each mode via the switch S3. It is controlled to turn on and off depending on the situation. (When dubbing, Detsuki D
The motor M1 of No. 1 is rotating, but the capstan and the pinch roller (not shown) are in contact with each other, and when the pause button is pressed, the switch S3 is open and no current flows to the motor M2. ) The mode changeover switch S2 consists of switches S2a and S2b that are interlocked with each other, and the motor M1 of the first switch D1 is connected to one side to the negative side of the power source V and the other to the positive side of the power source V through the switch S2a. are doing. The motor M2 of the second deck D2 connects one side to the pause switch S of the first deck D1.
3 to the negative side of the power source V, and the other to the positive side of the power source V through the mode changeover switch S4 of the second deck D2 and the dubbing changeover side 1 of the changeover switch S1, and the continuous recording of switch S4 and switch S1. It is connected to the positive side of the power supply V via the (re)side 2 and switch S2b.

The LED is a lamp that indicates the dubbing switching time, and both ends thereof are connected to the plus and minus sides of the power supply V through the dubbing switching side 1 of the switch S1, respectively. The switch S2 operates in the direction A when the recording or playback button is on in the first deck D1, turning on one switch S2a and turning off the other switch S2b, so that the lever is in a state where the record or playback button is off. is operated in the direction B to turn off one switch S2a and turn on the other switch S2b. Said pause switch S
3 is set so that it is turned off when the pause button is on, and turned on when the pause button is off. The switch S4 of the second deck D2 is turned on when the recording or playback button is turned on, and turned off when it is turned off.

In this way, when dubbing the contents of a cassette installed on the first deck D1 to a new cassette installed on the second deck D2, first switch the selector switch S1.
After switching to the dubbing side 1, turn on the pause button of the first deck D1, and then put the first deck D1 side into the playback state and the second deck D2 side into the recording state. At this time, the motor M1 of the first deck D1 is rotating, but the pinch roller is mechanically separated from the capstan so as not to run the tape, and the pause button is turned on to prepare for playback. The motor M2 is also in a recording preparation state because the pause switch S3 is turned off due to the pause button being turned on. Therefore, by releasing the pause button, the tape in the cassette of the first deck D1 is driven, while the motor M2 of the second deck D2 is driven.
Also, when the pause switch S3 is turned on, recording is driven. The dubbing indicator lamp LED lights up when the switch S1 is switched to the dubbing side 1.

Furthermore, after recording or playing back the cassette installed on the first deck D1, if you want to continuously record or play back the cassette installed on the second deck D2, first set the selector switch S1 to the continuous recording (playback) side.
, and turn on the recording or playback lever on the second deck. Then, when the first deck D1 auto-stops and the recording or playback button is turned off, these levers return to the lower direction of switches S2a and S2b, and switch S2a is turned off and the first deck is turned off.
Motor M2 of deck D1 stops and switch S2
When b is on, the motor M2 of the second deck D2 is driven to the recording or reproducing state via the switch S4. The second deck D2 is designed to automatically stop at the end of the tape. In addition, when continuous recording (re) is performed, switch S2b is closed and motor M2 is started to start the tape at the start of running.If it is a DC motor or a motor with similar characteristics, the speed will be instantaneously constant without any problems in terms of sound. There is no problem in using it.

As mentioned above, the present invention is equipped with a selector switch for selecting either dubbing or continuous recording (re) connected to the motors and mode selector switch of the two decks, and a pause button linked to the pause button of one deck. Connect the switch to the motor of the other deck, and turn on and off the motors of both decks according to each mode via the pause switch that works with the pause button.
Since the switch is turned off, dubbing or continuous recording (replay) operations can be switched electrically and automatically with a single switch, and furthermore, operations during dubbing can be performed on both decks using a single pause button. This has effects such as being able to control the drive of the motor.
