Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dubbing device for dubbing a reproduction signal of a CD player onto a cassette tape mounted on a cassette tape recorder.

[0002]

2. Description of the Related Art Generally, a means for dubbing a reproduction signal of a disc mounted on a CD player to a cassette tape mounted on a mechanically operated cassette mechanism is performed as follows.

That is, first, the cassette mechanism is set in a standby state and in a recording state to be in a recording standby state. At the same time as the cassette mechanism is released from the recording standby state, the CD player is operated to be reproduced or the cassette mechanism and the CD player are released from the standby state from the recording standby state and the CD player playing standby state.

As described above, the cassette mechanism is first put in the recording standby state, the CD player is reproduced, and the reproduction signal of the CD player is dubbed on the cassette tape.

[0005]

The above-mentioned conventional dubbing apparatus requires the cassette tape record side to put the cassette mechanism in the recording standby state and release it.
On the CD player side, the operation has to be performed in a timely manner corresponding to the side of the cassette tape recorder, and the dubbing operation is troublesome.

An object of the present invention is to eliminate the above-mentioned problems and to provide a dubbing device which makes it possible to dubb a reproduction signal of a CD player onto a cassette tape by a simple operation.

[0007]

A dubbing apparatus of the present invention is an audio device equipped with a CD player and a cassette tape recorder, wherein a reproduction signal of a disc mounted on the CD player is transferred to the cassette tape recorder. In a dubbing device for dubbing a mounted cassette tape, a recording unit having a function of recording a reproduction signal of the CD player on a cassette tape of a cassette tape recorder, and a microcomputer for controlling the CD player and the cassette tape recorder Input a command to, and operate the constant speed and high speed dubbing keys and the constant speed dubbing key to set whether the reproduction signal of the CD player is dubbed to the cassette tape loaded in the cassette tape recorder at constant speed or high speed. The recording means Dynamically start recording at constant speed, start constant speed playback of the CD player to start dubbing, and when the high speed dubbing key is operated, the recording means automatically starts recording at high speed. In addition, it comprises dubbing start means for starting high-speed reproduction of the CD player to start dubbing.

[0008]

By the above means, when the constant speed dubbing key is operated, the recording at the constant speed is automatically started, and
Start the constant speed reproduction of the CD player and start dubbing. When the high-speed dubbing key is operated, high-speed recording is automatically started, and high-speed reproduction of the CD player is started to start dubbing. This allows
By operating a constant speed or high speed dubbing key, the recording speed of the cassette tape recorder and the reproduction speed of the CD player can be automatically set, and the reproduction signal of the CD player can be dubbed to the cassette tape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, S1 is a reproduction leaf switch which is turned on when the head chassis is moved when the mechanical cassette mechanism is reproduced. Switch S
When 1 is turned on, the transistor Q1 is turned on when a voltage is applied from the power source + B1 through the resistor R1 and the diode D1. When the transistor Q1 is turned on, the base potential of the PNP type transistor Q2 in which a voltage is supplied from the power source + B2 to the emitter is lowered and the transistor Q2 is turned on. When this is turned on, the motor M that runs the cassette tape rotates, and the reproduction of the tape is started.

When the function switch FS is set to the position CDP of the CD player, the transistor Q3
The base of is biased on via the power supply + B3 and turns on. In this state, even if the regeneration leaf switch S1 is turned on, the transistor Q1 is turned off, the transistor Q2 is also turned off, and the motor M is temporarily stopped.

Similarly, the function switch FS is set to CD
When the cassette mechanism is operated for recording in the position CDP of the player, the reproduction switch S1 is turned on along with the movement of the head chassis, and the recording leaf switch S2 is turned on by operating the recording button. The ON information of the switch S2 is input to the microcomputer CPU, and the microcomputer CPU determines that the cassette tape recorder is in the recording state of the pause. In this state, the microcomputer CPU receives the input of the constant speed dubbing key and sends the motor control signal to the transistor Q via the resistor R3 and the diode D2.
Turn on 1 and Q2 to rotate the motor M and pause to start recording or start recording on the cassette tape recorder. At the same time, the microcomputer CPU outputs a control signal for rotating the motor M at a constant speed to the constant / double speed switching circuit SW so that the cassette tape recorder performs recording at a constant speed. For example, 1.2 seconds after the constant speed dubbing key ND is operated, the microcomputer CPU starts the reproduction of the CD player at a constant speed. This allows the reproduction signal from the CD player to be dubbed at a constant speed on the cassette tape.

Similarly, when the double speed dubbing key HD is operated, the microcomputer CPU controls the constant / double speed switching circuit SW,
The cassette tape radar is started in the double speed recording state, and the CD player is set to double speed reproduction after 1.2 seconds, for example. The reproduction signal of the double-speed CD player can be double-speed dubbed to the cassette tape of the double-speed cassette tape recorder.

When the function switch FS is switched to the position CDP of the CD player in this way, the mechanical cassette tape recorder can be temporarily stopped, and the dubbing key operation allows the CD cassette player to release the operation, facilitating the dubbing operation from the CD player.

Further, since the reproduction signal can be dubbed from the CD player at the speed corresponding to the operation of the constant / double speed dubbing keys ND and HD, the operation for dubbing can be simplified. Furthermore, after the recording of the cassette tape recorder has started, a predetermined time has passed, and then C
Since the D player is operated, the reproduction signal of the CD player is not interrupted and dubbed.

[0016]

As described above, according to the present invention, since the reproduction signal can be dubbed from the CD player at the speed corresponding to the automatically operated dubbing key, the operation for dubbing can be performed. It will be easy.
