一、概述 纸带光电输入机是电子数字计算机的一种输入设备。目前国内使用的大多是呼和浩特电子设备厂生产的摆杆式和无摆杆式的两种形式。前者是快启停的,使用了四个驱动电机,后者是慢启停的,用了三个驱动电机,并且都配有相应的伺服电路。 本文叙述的输入机在传动机构上作了特殊的考虑,只用一个驱动电机作动力源,代之伺服电路的只是一个开关电路,因而具有成本低,传动平稳,简单可靠的优点。 I. Overview Paper optical input machine is an electronic digital computer input device. At present, most of the domestic use of electronic equipment factory in Hohhot, pendulum-based and pendulum-free two forms. The former is fast start and stop, using four drive motor, the latter is slow start and stop, with three drive motor, and are equipped with the corresponding servo circuit. The input machine described in this paper makes special consideration on the transmission mechanism. Only one driving motor is used as the power source. Instead, the servo circuit is only a switching circuit, so it has the advantages of low cost, stable transmission, simple and reliable.
