Abstract: A video-phone device which transmits and receives sharable data to and from video-phones belonging to other parties is provided with a communication control means which, upon receiving a reception request or a transmission request for shareable data, assesses whether or not the reception request or the transmission request satisfies predetermined conditions, specifically, whether or not the other party has been stored in a recoding unit as a party to which transmission/reception of sharable data is permitted, and receives sharable data from the other party or transmits sharable data to the other party only when the conditions are satisfied. Thus the video-phone can automatically permit only reception of sharable data from trusted parties on the other end of a communication line, or transmission of sharable data to trusted parties on the other end of a communication line.

Abstract: In a telephone having a presence function, it is possible to easily register a presence state. The telephone includes: presence detection means for detecting a presence state of a user; a presence state storage unit for storing the presence state detected by the presence detection means; and control means having a presence modification function for modifying the presence information stored in the presence state storage unit according to the user presence state detected by the presence detection means. When the presence detection means has detected a presence of a user, the control means modifies the presence information stored in the presence state storage unit to presence information indicating a presence. When the presence detection means has detected an absence of the user, the control means modifies the presence information stored in the presence state storage unit to presence information indicating an absence.

Abstract: A communication device of the present invention is provided with an evacuation direction portion receiving an earthquake early warning, and outputting a text image or sound for an evacuation direction. If the earthquake early warning is received under circumstances where a time adjusting portion cannot assure the accuracy of time kept by a timekeeping portion, the evacuation direction portion gives an evacuation direction based on earthquake information unassociated with the time. The evacuation direction portion is provided with a plurality of kinds of evacuation direction images or sounds. The evacuation direction portion determines an image or sound to be used for the evacuation direction based on an expected time period before a main tremor arrives calculated by an earthquake information calculating portion. Moreover, an evacuation direction registering portion receiving from a user, selection of evacuation direction data that the evacuation direction portion uses is provided.
