    摘要： In a document printing machine comprising a plurality of interconnected modular sections, there is disclosed herein a printer module having a self container control system. Documents, to be printed upon, are sequentially passed through the printer module under the control and drive of either one of two different speed drive units. The second drive unit initially functions as a control gate to control the feeding of documents into the printer module. When the printing operation is to begin, the second drive unit moves the documents through the printer module at a positively controlled printing speed. After the printing operation, the first drive unit moves the documents out of the printer module at a high speed. In order to maintain the correct character pitch between adjacent serially printed characters, a timing unit is operatively connected to the first drive unit. This timing unit is responsive to drive variations and accurately divides each character pitch into a plurality of intervals. Each interval controls one or more printer operation functions including the actual print operation. In order to maintain the synchronism between the movement of the documents and the character pitch, the second drive unit is clutched from the first drive unit.

    摘要翻译： 在包括多个互连的模块部分的文件打印机中，这里公开了一种具有自我容器控制系统的打印机模块。 要打印的文件在两个不同速度驱动单元中的任一个的控制和驱动下依次通过打印机模块。 第二驱动单元最初用作控制门以控制将文档馈送到打印机模块中。 当打印操作开始时，第二驱动单元以正的控制打印速度移动文件通过打印机模块。 在打印操作之后，第一驱动单元以高速将文档移出打印机模块。
