    摘要: There is provided a liquid discharge head including a substrate, a ceiling plate connected to the substrate, a liquid flow path formed between the substrate and the ceiling plate, and a cantilever-like movable member having a fixed end fixed to the substrate and a free end extending into the liquid flow path, wherein the movable member is formed of a lower protective layer, a heat generating resistive layer, a lower electrode layer, an insulating layer, an upper electrode layer, and an upper protective layer stacked from the side of the substrate in the mentioned order, and wherein application of a voltage to a heat generating portion of the heat generating resistive layer causes bubbling of a liquid in the liquid flow path between the movable member and the substrate to discharge the liquid.

    摘要: A high-quality image conforming to the scanning speed of a recording head can be recorded through a simple arrangement in which 128 recording elements (segments) are divided up into eight blocks (each block comprising 16 segments). In order to perform recording by the initial block, a code of the corresponding three bits is supplied to a 3to8 decoder, whereupon a signal BE1 is outputted to made segments 1, 2, 17, 18, . . . , 113, 114 the object of drive. When a signal ODDENB attains a high level, segments 1, 17, . . . , 113 are driven and dots are formed at recording column positions by each segment. By subsequently sending a signal EVENENB to the high level, segments 2, 18, . . . , 114 are driven. Here the interval between the signals ODDENB and EVENENB is changed in conformity with the scanning speed of the recording head.
