Abstract: An object of the present invention is to provide an image communication apparatus capable of preventing the useless use of not-cheaped BJ ink owing to the innocent behavior of an infant or the like, and capable of preventing the disturbance of the rhythm of a home life by a cat or the like. An image communication apparatus includes operation instructing means for instructing reading operation, image processing operation, image recording operation, calling operation and communication operation; and operation instruction disabling means for disabling an instruction of each operation by the operation instructing means.

Abstract: Even in an apparatus connected to another apparatus which periodically transmits a command, a mode transition such as transition to a power saving stand-by mode can be performed. A mode change for Bluetooth communications and a mode change in a stand-by state are performed in cooperation with each other to efficiently switch between stand-by modes.

Abstract: Wireless mode between a scanner and an image communication apparatus is changed when the scanner completes read of an image, when the image is sent from the scanner to the image communication apparatus by the operation of the scanner, or depending on presence or absence of read original, and for example, low power consumption mode and communication mode are switched to each other.

Abstract: A facsimile apparatus sends a quasi-ring back tone to a destination in response to a call from the destination, and detects a CNG from the destination while the apparatus is periodically sending the quasi-ring back tone to the destination. When the apparatus detects a CNG for the first time, the apparatus stops sending the quasi-ring back tone and then performs facsimile communication in response to a second detection of a CNG from the destination, so as to certainly detect the CNG and to quickly shift to facsimile communication.
