美国 ACT 公司最近发表了ACT900型打印机,该机采用微处理机和电子元件代替了以往占据中速打印机中大部分空间的复杂机械元件,还简单地包含了很多附加机构,同时还与其他装置和接口有很高的相容性。该机的打印头采用了简单的螺丝驱动伺服控制,纸张进给是由步进电机执行。微型计算机的中心是 Inte14004微处理机。机器中没有机械离合器、弹簧、皮带等,也没有除了操作控制和印字筒反转开关以外的机械开关。
ACT Corporation of the United States recently published the ACT900 printer, which uses microprocessors and electronic components to replace complex mechanical components that used to occupy most of the space in a medium-speed printer. It also includes many additional mechanisms, along with other devices and Interface has a high compatibility. The machine’s print head uses a simple screw-driven servo control, paper feed is performed by the stepper motor. The center of the microcomputer is the Inte14004 microprocessor. There are no mechanical clutches, springs, belts, etc. in the machine, and no mechanical switches other than the operation controls and the print cylinder reversing switch.
