Abstract

PURPOSE:To operate and adjust a sound recording level without any problem even when the sound recording condition is obtained in order to match a sound recording level and the sound recording is executed by interlocking with a CD part by displaying the level sound-recorded with a level meter even in the reproducing condition. CONSTITUTION:An input change-over switch 17 is provided instead of a sound recording switch. Namely, the signal amplified by a line amplifier 7 is impressed to an output terminal 8 and simultaneously, impressed through a fixed resistor 9 to a sound recording mode change-over switch 10. The input change-over switch 17 is connected to the A side of the sound recording mode change-over switch 10. For the input change-over switch 17, since a fixed resistor 14 is connected to a C side tape position, a sound recording level cannot be made variable, a sound recording level volume 13 is connected by (a), (b) side tuners and a DC position and even at the time of the reproducing condition, a level meter 16 displays the sound recording level. Thus, at the time of the input from the tuner and the CD, the sound recording level can be operated and adjusted by the sound recording level volume even when the sound recording condition is not obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a level display device for a tape recorder.

Conventional technology Conventionally, the level display device of a tape recorder displays the playback level when the tape recorder is in the playback state, and displays the output level of that input when the tape recorder is playing and the input selector switch is set to another input. The tape recorder must be in recording mode to display the recording level.

FIG. 2 shows a conventional example. In FIG. 2, the recording/reproducing head 3
The signal converted into an electrical signal is applied to a reproducing amplifier 5 via a recording/reproducing switch 4.

The recording/reproducing switches 4 and 12 are on the A side during playback and on the A side during recording. The signal amplified by the reproducing amplifier 5 is applied to the C terminal of the input selector switch 6. In the input selector switch 6, the signal from the tuner section 1 is applied to the a terminal, and the signal from the compact disc section (hereinafter referred to as CD section) is applied to the b terminal.
applied to the terminal. In the current position of the input selector switch, the signal at the C terminal is applied to the line amplifier 7, amplified and output from the output terminal 8, and simultaneously connected to the fixed resistor 9.
The signal is applied to the recording mode changeover switch 10 via the signal. A fixed resistor 11 is connected to the B side of the switch 1o, and the recording level cannot be varied. A of the above switch 10
The side is connected to the recording/reproducing switch 12. The recording/playback switch 12 is set to the A side during playback, and the recording level cannot be varied because it is connected to the fixed resistor 14, but it is set to the A side during recording, and the recording level volume control is connected, making it possible to vary the recording level. can. The level of the signal is displayed on the level meter 16 and applied to the recording amplifier 15, and the amplified signal is applied to the A side of the recording/playback switch 4. During recording, the signal is recorded onto the magnetic tape by the recording/playback head 3. Ru.

Problems to be Solved by the Invention However, in such a conventional level display device, in order to adjust the recording level using the recording level polyurethane 13, it is necessary to enter the recording state. In a tape recorder that is configured to record on magnetic tape in conjunction with the CD section or to stop at -, the magnetic tape is recorded while the recording level is adjusted using the recording level polyurem. There was a problem with this. The present invention solves the above problem, and by displaying the recorded level on a level meter even in the playback state, it can be used to set the recording state to match the recording level or to record in conjunction with the CD section. It is an object of the present invention to provide a level display device that allows the recording level to be operated and adjusted without any problems.

Means for Solving the Problems In order to achieve the above object, the level display device of the present invention has an input changeover switch connected between a recording mode changeover switch and a recording level polyurethane.

Effect of the Invention With the above-described configuration, the present invention allows the recording level to be operated and adjusted using the recording level volume control when inputting from a tuner or CD, without having to enter the recording state.

Example.

FIG. 1 is a circuit diagram of a level display device in one embodiment of the present invention. The difference between FIG. 1 and FIG. 2 is that an input selector switch 1a is provided in place of the recording/reproducing switch 12. The operation of this input selector switch 17 will be explained. The signal amplified by the line amplifier 7 is applied to the output terminal 8 and simultaneously applied to the recording mode changeover switch 1o via the fixed resistor 9. An input changeover switch 17 is connected to the A side of the recording mode changeover switch 10. The input selector switch 17 cannot change the recording level because the fixed resistor 14 is connected to the tape position on the C side, but the recording level polyurethane 13 is connected to the tuner and CD positions on the a and b sides, so that playback cannot be changed. Even in this state, the level meter 16 displays the recording level w.

Effects of the Invention As described above, according to the present invention, when recording signals from a tuner or CD, the level meter displays the recording level even if the tape recorder is not in the recording state. The volume can be adjusted, and the recording level can be set without any problem even in a tape recorder configured so that CD and tape recording are linked. When recording with tape, the recording level polyureum is not connected.

This is because when a recorded tape is played back, the level display value of the level meter 16 changes depending on the recording level volume even when the recorded level is played back, so it is necessary to switch the recording mode changeover switch 1o to the B side. This is to prevent such operations from becoming complicated.
