Abstract: A length of a melamine foamed block to be accommodated in an ink tank housing as measured in the longitudinal direction is dimensioned to be larger than a length of the ink tank housing as measured in the longitudinal direction. Thus, while the foamed block is accommodated in the ink tank housing, it is compressed in the direction orienting toward an ink feeding port from which ink is fed to a printing head, i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block, resulting in an ink feeding capability of the printing head being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block is intensified.

Abstract: A visual telephone apparatus of the present invention is capable of deciding whether the apparatus of the other party of communication is a normal telephone apparatus or facsimile equipment by the operator who hears the data received from a connected communication medium or automatically by analysis of the procedure of controlling the communication with the apparatus of the other party, and transmitting the data obtained by photographing a subject in accordance with the communication specification corresponding to the apparatus decided, as well as receiving the data from the apparatus of the other party in accordance with the communication specification corresponding to the apparatus decided and displaying the data on a display unit. The apparatus is also capable of visual telephone communication with a visual telephone set and facsimile communication with facsimile terminal equipment.
