Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a telephone, and more particularly to the structure of a panel provided in a communication device body and opened and closed.

[0002]

2. Description of the Related Art A communication device such as a telephone is often provided with a panel that opens and closes via a rotary shaft portion. FIG.
The opening / closing panel 21 provided at the upper corner position of the telephone is configured to be opened / closed via the rotating shaft portion 22. However, a sound source unit such as a speaker is provided inside the telephone, and this sound source unit may act as a vibration source when producing sound, and may cause a rattling sound in the panel 21.
This is because there is a backlash between the panel 21 and the telephone body 23, or the panel 21 is easily lifted due to a rotation moment, which causes a resonance phenomenon. Therefore, conventionally, when configuring the panel 21,
The design accuracy has been improved so that no looseness is generated between the telephone body 23 and the telephone body 23, and a slight tension is applied to the panel 21 to suppress resonance.

[0003]

However, in constructing the panel 21, so-called backlash is driven in at the rotary shaft portion 22 or the panel 21 is slightly moved so that there is no looseness in fitting with the telephone body 23. Even if the tension is applied, it is difficult to sufficiently prevent chattering when the action of the rotation moment of the entire panel 21 is large. Further, if the panel 21 is opened at night or the surroundings are dark, it is inconvenient to use the inside of the panel 21. The present invention is proposed to solve such a problem, and prevents the panel from making a chattering noise due to a resonance phenomenon even when an internal device of a communication device operates and vibrates. The purpose of the present invention is to provide a communication device.

[0004]

DISCLOSURE OF THE INVENTION The present invention is proposed in order to solve the above-mentioned inconvenience, and has a vibration source inside the main body, and a panel which is opened and closed via a rotary shaft part in a part of the main body.
