印字、扫描、复印多功能一体化外设设计

Design of a Multifunction IntegrativePeripheral with Printing,Scanuing and Copying Capabilities

多功能外设（MFP：MultifunctionPeripherals）是计算机外设的一个重要发展方向。笔者所研制的新型多功能外设集热敏／热转印印字、扫描、复印三功能于一体。该MFP可以作为独立的打印机、扫描仪和复印机使用。它可以实现脱机复印。文章介绍了该MFP的性能特点、控制电路的组成与设计。

Multifunction peripherals (MFP) is an important developing direction of peripherals used for computer. A new kind of MFP which we developed combines thermal sensitive / thermal transfer printing with scanning and copying ca pabilihes in one body. This MFP can acts as a stand-alone printer, scanner and copier. It can perform copying function without being hooked to a PC. Here,our MFP's characteristics, compositions and designs of its control cireuits are de scribed.
