BGCFX型五单位步进光电式穿复校机,是一种新型的计算机外部设备。它是根据电子计算机的使用需要而设计的专用设备。该机具有高速自动校验纸带,自动复制纸带,和根据所编的程序对纸带进行手工穿孔等功能。以往,上机前的准备工作——包括手工穿孔、上机源程序、数据纸带的奇偶校验和复制,以及上机后由快速穿孔机穿出的新纸带的奇偶校验等等,一般都是用手工或者利用大型电子计算机加以完成。
BGCFX five-unit stepper photoelectric cross-correction machine, is a new type of computer peripherals. It is based on the use of computer needs and design of special equipment. The machine has a high-speed automatic calibration tape, tape automatically copied, and according to the procedures for the tape by hand perforated and other functions. In the past, preparatory work on the machine - including manual perforation, the source program, data tape parity and copy, as well as after the machine punched out by the fast punch new tape parity and so on, It is usually done by hand or using a large electronic computer.
