JPS5814416Y2 - Tape recorder recording level control device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording level control device for a tape recorder.

There are popular types of tape recorders that only have a so-called automatic level adjustment circuit that automatically adjusts the recording level, and high-end types that allow you to manually adjust the recording level. Some devices allow you to automatically adjust the recording level depending on the type of recording, or manually adjust the recording level.

A tape recorder having both of these level adjustment functions is provided with a switch for controlling the on/off operation of the automatic level adjustment circuit, and is also equipped with a level meter used when manually adjusting the recording level.

In addition, some tape recorders with the shape shown in Figure 1 have a level meter that is difficult to see, so the level meter is formed protruding from the top surface of the cabinet, but if a part of the meter is made to protrude, it is easier to carry than with a portable tape recorder. In the device used for this purpose, a portion of the meter protrudes, which poses an obstacle when carrying the device.

The level meter is necessary when the recording level is adjusted manually, but is not necessary when recording is performed using an automatic level adjustment circuit.

The present invention has been developed in view of these points, and will be described in detail below with reference to the drawings.

Figure 1 is a perspective view showing the tape recorder of the present invention, Figure 2 is a perspective view showing the tape recorder of the present invention.
The figure is a sectional view of the main part.

In the figure, 1 is the cabinet that constitutes the tape recorder, 2 is the cassette tape insertion part, 3 is the operation button for recording, playback, fast forward, etc., and 4 is the operation knob that is operated when manually adjusting the recording level. .

Reference numeral 5 denotes a level meter for displaying the recording level, which is attached to the cabinet 1 so that it can be stored, and the button shown in FIG. 1 is in the stored state.

The level meter 5 is rotatably mounted on a shaft 6 and biased toward the non-storage state by a spring (not shown), and is locked by a locking means (not shown) when the level meter 5 is in the storage state. It is configured to be held in the stored state.

Figure 2 shows the state in which the level meter 5 is not stored, and in the figure, 7 is an automatic level adjustment circuit etc. that automatically adjusts the recording level according to the magnitude of the recording signal. The printed circuit board 8 to which wiring is attached is a control switch that is attached to the printed circuit board 7 and controls the on/off operation of the automatic level adjustment circuit.

9 is a holding member 10 to which the level meter 5 is attached.
an elastic switching member having one end fixed to the
When the level meter 5 is moved to the stored state, the switch 11 of the control switch 8 is pressed and displaced to switch the control switch 8 and turn on the automatic level adjustment circuit.

The switch 11 constituting the control switch 8 has a spring (
(not shown) in the direction of arrow A, and the second
In the state shown in the figure, that is, when the level meter 5 is in the non-accommodated state, the automatic level adjustment circuit is in the OFF state.

The control switch 8 not only controls the on/off operation of the automatic level adjustment circuit, but also disables manual level adjustment when the automatic level adjustment circuit is in the ON operation state, and controls the automatic level adjustment circuit. When the level adjustment circuit is in the OFF operating state, it functions to enable manual level adjustment.

The present invention is constructed as described above, and its operation will be explained next.

First, when recording music, it is necessary to accurately adjust the recording level, so it is desirable to adjust the recording level manually in this case.

Therefore, by placing the level meter 5 in the non-storage state as shown in FIG. 2, the automatic level adjustment circuit is turned off.
You will need to operate the to adjust the recording level.

When recording the contents of a meeting, it is more convenient to record using an automatic level adjustment circuit, since there is no need to adjust the recording level accurately.In this case, it is necessary to check the level meter 5. There isn't.

Therefore, when the user stores the level meter 5 in the cabinet 1 as shown in FIG. 1, the control switch 8 is switched by the rotational displacement of the switching member 9 due to the storage of the level meter 5, and the automatic level adjustment circuit is turned on. becomes operational.

Therefore, the automatic level adjustment circuit automatically adjusts the level of conversations such as meetings, etc., and records them on magnetic tape.

As explained above, the present invention is to install a level meter so that it can be stored in a cabinet, and to store the level meter in the cabinet when recording using an automatic level adjustment circuit that does not require the level meter. The automatic level adjustment circuit is turned on by switching the control switch that controls the on/off operation of the automatic level adjustment circuit, which is not only extremely convenient to operate, but also eliminates the need for manual operation. When adjusting the recording level, the level meter is placed in the non-accommodated state and automatically enters the manual level adjustment state, which makes it easy to see and allows manual level adjustment to be performed easily.

Furthermore, since the level meter can be stored in the cabinet, it is convenient to carry, and when implemented in a portable tape recorder, it is extremely effective.
