Description

  The present invention relates to a communication device connected to a wide area communication network and performing communication, and more particularly to a communication device that receives an emergency earthquake bulletin distributed by the Japan Meteorological Agency and issues an evacuation instruction.

  In recent years, with the development of communication infrastructure, various additional services related to communication have become widespread. For example, telephone devices that can connect to a wide-area communication network such as an IP telephone network or the Internet and receive various services such as a data communication service have become widespread.

  As one of the functions provided in such a communication device, there is a function for receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency when an earthquake occurs. Earthquake early warning is an information distribution service that will be implemented from October 1, 2007 AD. The user can use this service by purchasing a communication device corresponding to the earthquake early warning and making a contract with a distribution service company for the earthquake early warning.

  A communication device that has received an earthquake early warning when an earthquake occurs uses local information recorded in advance in the communication device, for example, latitude / longitude information of the location where the communication device is installed, etc. Of earthquake motion, the part most felt by the human body (usually the S wave) is calculated.

  The calculation result is notified to the user, for example, by displaying an image on a liquid crystal panel or outputting sound through a speaker. Thus, the user can take an evacuation action such as hiding under the desk or extinguishing the source of the fire before the main motion arrives from the epicenter.

Various technologies related to emergency earthquake warnings are disclosed in published patent gazettes. For example, in Patent Document 1, when emergency earthquake information is received, there is an allowance time until the main motion comes from the current position and emergency earthquake information. And a communication terminal capable of calculating the convergence time of the main motion and displaying the calculation result.
JP 2007-47936 A

In the technique described in Patent Document 1, information related to earthquakes is displayed on the display unit. However, not only the display unit but also a plurality of lamps (for example, LEDs (Light Emitting Diodes)) are mounted, If it is possible to notify that an earthquake will be coming soon by flashing, it is preferable because it becomes easier for the user to detect that an earthquake is coming. However, even if a plurality of lamps are mounted in various places, the lamps may be covered with objects or furniture depending on the installation method or usage method of the telephone device. Even if the lamp is lit or blinked in such a state, useless power is consumed.

  This invention is for solving the above subject, and enables a user to select the notification lamp which lights or blinks among several notification lamps.

The communication device according to claim 1 is a communication device having a substantially rectangular parallelepiped shape and light emitting portions that are lit or blinking at four corners of the rectangular parallelepiped, and the communication device receives an emergency earthquake warning. And an input unit for setting the light emitting unit to be turned on or blinking when the receiving unit receives the earthquake early warning, and information on the light emitting unit selected by the operation of the input unit. A storage unit and a control unit, and when the receiving means receives the earthquake early warning in a state where the information of the light emitting unit selected by the operation of the input unit is stored in the storage unit, the control unit However, the light emitting unit is turned on or blinked based on information on the light emitting unit stored in the storage unit .

  Since the user can select the incoming lamp that is lit or blinking, the incoming lamp that should be lit or blinked can be selected according to the arrangement form of the communication device.
