    • 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.
    • 可以通过简单的布置记录符合记录头的扫描速度的高质量图像,其中128个记录元件(段)被划分为八个块(每个块包括16个段)。 为了通过初始块执行记录,将相应的三位的代码提供给3to8解码器,由此输出信号BE1以使其成为段1,27,18。 。 。 ,113,114是驱动器的对象。 当信号ODDENB达到高电平时,段1,17。 。 。 ,113被驱动,并且在每个段的记录列位置处形成点。 通过随后将信号EVENENB发送到高电平段2,18。 。 。 ,114被驱动。 这里,信号ODDENB和EVENENB之间的间隔根据记录头的扫描速度而改变。
