A method for the discharge of a liquid and a liquid discharge head are provided which produce stable discharge of the liquid and, at the same time, facilitate the supply of the liquid by repressing the oscillation of a movable separation membrane during the extinction of bubbles. The method comprises using a movable separation membrane for separating a first flow path communicating with a discharge port for discharging the liquid and a second flow path furnished with a bubble generating region for generating bubbles in the liquid by the use of a heating element, disposing a movable member opposed to the bubble generating region across the movable separation membrane and furnished with a free terminal in the direction of liquid discharge, causing separation between the movable separation membrane and the movable member during the contraction of the bubbles, and inducing the intrusion of the liquid therebetween.

A length (c) of a melamine foamed block (12) to be accommodated in an ink tank housing (11) as measured in the longitudinal direction is dimensioned to be larger than a length (C) of the ink tank housing (11) as measured in the longitudinal direction. Thus, while the foamed block (12) is accommodated in the ink tank housing (11), it is compressed in the direction orienting toward an ink feeding port (13) from which ink is fed to a printing head (14), 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 (12), resulting in an ink feeding capability of the printing head (14) being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block (12) is intensified.

An ink tank for storing ink supplied to an ink jet recording head comprises an ink tank body, an ink absorbing member inserted in the ink tank body in a compressed state, an atmosphere communicating port for communicating an inner space of the ink tank body with the atmosphere, and an ink supply port coupled to the ink jet recording head and serving as an ink supply port. A corner of the ink absorbing member which would be located near the atmosphere communicating port is cut out, a portion of the ink absorbing member around the cutout area is partly released in a degree of compression as compared with the other portion thereof under the state where the ink absorbing member is inserted in the ink tank body in a compressed state, and a space area is formed between the cutout area of the ink absorbing member and the atmosphere communicating port. The ink absorbing member is prevented from entering a buffer chamber, the ink impregnated in the ink absorbing member is uniformly supplied to the recording head, and the ink is prevented from leaking to the outside even if the cartridge is subjected to a thermal impact or a pressure reduced state.

Information transmitted through radio is recorded in telephone communications using radio. Provision is made of a radio wave receiving portion 42 for receiving a radio wave signal, a voice data holding portion 43 for demodulating the radio wave signal received by the radio wave receiving portion 42 into voice data, and holding it, a data converting portion 44 for converting the voice data held by the voice data holding portion 43 into a character code, an image data holding portion 45 for converting the character code converted by the data converting portion 44 into image data, and holding it, a recording element portion 47 for recording the image data held in the image data holding portion 45 on a recording medium 60, a synchronous signal outputting portion 46 for outputting a synchronous signal synchronized with the timing at which the image data held in the image data holding portion 45 is delivered to the recording element portion 47, and a motor 48 for conveying the recording medium 60 on the basis of the synchronous signal outputted from the synchronous signal outputting portion 46.
