Abstract: An image communication apparatus in which a mobile telephone set of a cordless telephone device is connected with a facsimile device through a connector and in which the connection of a telephone line of the mobile telephone set with a communnication unit of the facsimile device is controlled on the basis of the state of the connection and the state of a telephone line for facsimile communication. A connection cord for the facsimile device is not required which enables free movements of an operator and the devices. Further, no additional parts such as an acoustic coupler and no manual operations are required when a call is originated or received, and facsimile communication can be made easily from any place.

Abstract: A facsimile apparatus capable of informing an operator of data such as operable time of the facsimile apparatus, the number of documents transmittable and receivable based on the quantity of electric charges remaining in the battery comprises a clock for generating time data and a monitor for monitoring the quantity of electric charges remaining in the battery. The monitor calculates the charging time of the battery based on the time data. The charged quantity of the battery from the time when the battery started to be charged to the current time is determined from the charging time. The operation time of the facsimile apparatus driven by the battery in each of the operation modes is calculated based on the time data. The consumed quantity of electric charges in the battery is measured from the operation time. The quantity of electric charges remaining in the battery is calculated from the charged quantity and consumed charge quantity.
