Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call notification carried by a user in order to notify the user of an incoming call state in a portable communication device such as a portable telephone or a small portable receiver for wireless calling that can be put in a pocket. It concerns the device.

[0002]

2. Description of the Related Art In recent years, portable telephones, PHSs (personal
Portable communication devices such as a handy phone system) and a small portable receiver for wireless calling (so-called pager) have been remarkably popularized. These portable communication devices are usually housed in large bags or outer pockets, and are carried by the user in a state of being shielded from the outside. For this reason,
In order to notify the user that these portable communication devices have arrived, a relatively loud ringing tone is required. However, public places (such as restaurants and trains)
Such loud ringtones in are prone to disturb the surroundings.

Therefore, instead of such an annoying loud ringing tone, for example, a conventional affiliated telephone is provided with an incoming call notifying mechanism such as a vibration calling function (so-called vibrator function). Such an incoming call notification mechanism is controlled based on an incoming signal for ID confirmation and the like transmitted from the mobile phone to the base station when a radio wave from the base station arrives at the mobile phone. In addition, for example, Japanese Utility Model Publication No. 3038786 discloses a personal accessory having a mobile phone incoming call notification mechanism using the above-mentioned incoming call signal.

[0004]

The frequency band of radio waves used for mobile phones and PHSs is limited according to the type of communication device (typically 800 MHz, 1.0 MHz).
(5 GHz or 1.9 GHz band), the frequency of the incoming signal transmitted from each communication device (terminal) is the same in the same class of communication devices. Therefore, depending on the incoming call notification mechanism based on an incoming signal of a mobile phone or the like as described above, when a large number of users using the same class of mobile phone or PHS are in the vicinity, communication from a communication terminal used by the other person is possible. In some cases, the incoming call notification mechanism provided in a communication device or the like owned by the user operates erroneously due to the incoming signal. For this reason, the user operates the incoming call notification mechanism based on the fact that his / her portable communication device is in the receiving state, or based on the fact that the same type of portable communication device used by another person is in the receiving state. In some cases, it was necessary to check for malfunctions.

SUMMARY OF THE INVENTION The present invention is to solve the problem of the conventional incoming call notification mechanism based on an incoming signal from a terminal. The purpose of the present invention is to solve the problem without interference of a portable communication device owned by another person. The purpose of the present invention is to provide an incoming call notifying device for surely notifying the user of only the incoming call state of the portable communication device owned by the user.

[0006]

In order to achieve the above object, according to the present invention, there is provided a transmitter which is mounted on or close to a portable communication device and which receives a ringing tone generated from the portable communication device in a receiving state. A transmitter for providing a microphone for sounding and transmitting an incoming call notification signal based on the reception of the ringing tone by the microphone; and a portable receiver for detecting the incoming call notification signal. A portable communication device incoming call notifying device (hereinafter, referred to as the "first embodiment of the present invention") including a portable receiver having a notifying means for notifying a user that the portable communication device is in an incoming state based on detection of a signal. Incoming call notification device ”). In this specification, “mobile communication device” means
It is a term that generally refers to a configurable communication terminal that can be used for wireless communication, and includes a typical portable telephone, a PHS, and a small portable receiver for wireless calling that can be put in a pocket.

Then, the user can be informed that the portable communication device is in a receiving state by the notifying means provided in the portable receiver that has received the incoming notification signal. As described above, the incoming call notification mechanism in the first incoming call notification device of the present invention is based on the ringing tone emitted from the mobile communication device, and thus has a frequency different from the frequency of the incoming signal transmitted from the mobile phone to the base station, for example. It is possible to use an incoming call notification signal, and to operate erroneously based on an incoming signal from the same type of communication device (mobile phone) held by another person around yourself as in the above-mentioned conventional incoming call notification mechanism. There is no. Therefore, according to the first incoming call notification device of the present invention, it is possible to surely know that the portable communication device owned by the user is in a receiving state without being interfered by the portable communication devices owned by other persons in the vicinity. Can be. In addition, the transmitter is provided with a microphone so as to be attached to or used in close proximity to the portable communication device.

For this reason, by changing the type (thickness, size, etc.) of the crystal unit, it is possible to easily and inexpensively make the frequency of the incoming notification signal different for each transmitter. Thus, it is possible to manufacture various types of transmitters in which the frequencies of the incoming call notification signals transmitted from the transmitters are different from each other without increasing the cost. Therefore, according to the second incoming call notification device of the present invention,
It is possible to provide a user with various types of portable communication device incoming call notification devices having different frequencies of the incoming call notification signal. For this reason, for example, even if one user has two types of portable communication devices (for example, an analog portable telephone terminal in the 800 MHz band and a PHS terminal in the 1.9 GHz band) at the same time, the incoming call notification signal is generated. By preparing two types of incoming call notification devices having different frequencies and attaching each transmitter to a different mobile communication device, it is possible to separately and independently identify which mobile communication device is in a receiving state.
