摘要： The invention relates to a method and a device for controlling vertical scan speed when a document (10) and a recording medium are moved in a vertical scanning direction to read the document (10) and record signals on the recording medium, the read signals are stored in a line buffer memory (50) and code signals corresponding to the read signals in a code buffer memory (70). The present invention changes over a high speed vertical scan mode with hysteresis to a low speed vertical scan mode and vice versa in accordance with the number of buffered code bits in the code buffer memory (70) to read the document and record the signals on the recording medium. Thus, the present invention reduces the number of stops of vertical scan.

摘要翻译：本发明涉及一种方法和装置，用于当文件（10）和记录介质在垂直扫描方向上移动以读取文档（10）并在记录介质上记录信号时，控制垂直扫描速度，读取信号为存储在行缓冲存储器（50）中，并且与代码缓冲存储器（70）中的读信号相对应的代码信号。本发明根据代码缓冲存储器（70）中读取文件的缓冲代码位的数量，将具有迟滞的高速垂直扫描模式改变为低速垂直扫描模式，反之亦然，将信号记录在记录介质上。因此，本发明减少了垂直扫描的停止次数。
