Abstract: In the handheld terminal device, when a message reception unit receives from a host computer a new arrival message indicating a new arrival of a file (or electronic mail), a control unit analyzes the new arrival message to obtain identifier information for identifying the file (or electronic mail) and a telephone number of the host computer. After a line connection to the host computer is established by a handheld phone transceiver unit, a fetch request command for fetching the file (or electronic mail) is transmitted to automatically fetch the file (or electronic mail) from the host computer and make the user know the contents of the file (or electronic mail) by using a display unit. A FAX transmitting user designates a destination handheld terminal device and transmits FAX image data to a communication server (CS). CS stores the received FAX image data and transmits a FAX arrival message to a pager connected to the destination handheld terminal device.

Abstract: A schedule management system which can display a schedule on a screen and enables the user to enter schedule topics promptly and accurately without performing complicated operation is provided. An external voice is input through a microphone or a network control unit and is converted into a digital signal by an A/D converter and a coder. An identifier related to the digital signal is generated. The identifier is displayed on a schedule on a display unit. The digital signal is stored in a memory in relation to the identifier. A user specifies the displayed identifier through an operation section, whereby the digital signal related to the identifier is extracted from the memory by a CPU, the extracted digital signal is converted into an analog signal by a D/A converter, and the analog signal is output as a voice through a loudspeaker or the network control unit to the outside. Like a voice, an image can also be handled.
