DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone, a PHS
Or when a mobile phone such as a car phone is called
The present invention relates to a call notification device for a mobile telephone that can be notified by a display or vibration by a D or a moving doll.

[0002]

2. Description of the Related Art In recent years, mobile telephones such as portable telephones have become widespread, but the ringing sound of the mobile telephones is generally offensive tones. Therefore, in public places, the ringing tone may bother others, and since it is impossible to make a ringing tone in a seminar or a concert hall, the telephone is turned off. Furthermore, the ringing sound may not be heard in a place where noise or noise is severe.

In order to cope with such a situation, in recent years, there has been provided a silent notification means such as a light-emitting display unit and a vibrating unit instead of a ringing tone in a mobile telephone itself. It cannot deal with a large number of mobile telephones without any.

Therefore, in order to cope with the above-mentioned problem even in a mobile telephone having no silent notification means, a radio signal emitted from the mobile telephone during reception or communication is received by an antenna to activate a display unit such as an LED. Small call notification devices have been developed.

[0005]

In order for a mobile telephone to accurately receive a radio signal emitted during reception or communication, a length of about several cm is required as an antenna.

[0006] On the other hand, small display devices of this type are often used by hanging them on noticeable places, for example, in bags or clothes, and therefore, it is extremely important to improve the appearance and commercial value. Therefore, the antenna may be wired inside the hanging strap of the device, or wired in a watch band in a wristwatch-type notification device as disclosed in Japanese Patent Application Laid-Open No. 8-146161. The length antenna is hidden.

[0007] However, the suspending string and the band are easily damaged by an unexpected external force, and the antenna may be cut off due to the damage, so that the radio signal may not be properly received.

[0008] Further, since such a small call notification device is mass-produced in units of tens of thousands, it is very important to improve the productivity in order to reduce the cost. In the case of the device embedded in the device, the handling is complicated and it is difficult to improve the productivity.

Accordingly, an object of the present invention is to reduce the frequency of breakage of the antenna and improve productivity by devising a method of implementing the antenna.
