Image communicating apparatus with direct supply of power from a battery to various units

摘要

An image communication apparatus has a read unit for reading a document sheet image and a battery power supply. The read unit has a voltage conversion unit for converting power supplied directly from the battery power supply. Other units, such as a recording head and a motor drive unit, may also receive power directly from the battery. A modified thermal head design is used to provide response equal to that obtainable with a higher-voltage supply.
