Abstract: A communication device is provided, which includes a controller configured to select a first bandwidth, calculates a first communication time for transmitting data using the first bandwidth, to sum one or more periods of a first charging unit time for the first bandwidth to calculate a second communication time that is equal to or longer than the first communication time and closest to the first communication time, to calculate a data amount of a terminal data section to be transmitted within a last period of the first charging unit time, and to select a second bandwidth for transmitting the terminal data section at a lowest communication fee within a second charging unit time for the second bandwidth, the controller controlling a communication unit to transmit data other than the terminal data section using the first bandwidth and transmit the terminal data section using the second bandwidth.

Abstract: A telephone device is capable of receiving, during communication with a first external device, a call from a second external device. The telephone device includes a setting unit and a ring alert inhibiting unit. The setting unit is configured so as to be capable of setting the telephone device to either one of a first status, in which a user of the telephone device wants to perform communication, and a second status, in which the user does not want to perform communication, the setting unit being configured so as to be capable of setting the second status, either when communication is started with the first external device, or while the communication with the first external device is being executed. The ring alert inhibiting unit inhibits a sound of a ring alert for informing that a call has been received from the second external device when the telephone device is in the second status.

Abstract: A facsimile apparatus includes a document size detecting unit, a first image data generating unit, a size acquiring unit, a size comparing unit, a second image data generating unit, an image data transmitting unit, and a first transmission result outputting unit. The document size detecting unit detects a first size of a first document. The first image data generating unit generates first image data based on a first image on the first document. The size acquiring unit acquires a second size of a second document that can be received by a reception-side apparatus. The size comparing unit compares the first size with the second size. The second image data generating unit generates second image data for forming a second image on the second document from the first image data based on a comparing result of the size comparing unit. The image data transmitting unit transmits the second image data to the reception-side apparatus.
