摘要: 本装置属于一种IC卡读写器的改进技术,其联接是在控制器上单独装有时钟电路,然后由二个与非门控制,其中一路可直接通过非与门,输出联接对象设备端,另一路与时钟振荡器同时通过与非门,再通过上一个非与门电路,输出时钟信号,这样就可兼控两种时序电路信号的输出,优点:电路结构简单,安装使用方便,可对两种IC卡时序电路同时进行读写,大大提高了设备利用率。
英文摘要: The utility model belongs to a technique for the improvement of an IC card reader-writer. A controller is solely provided with clock circuits controlled by two NAND gates, wherein, one circuit can directly pass through a not AND gate, and the output terminal of the circuit is connected with an object equipment terminal the other circuit and a clock oscillator can simultaneously pass through the NAND gates and the not AND gate circuit, and clock signals can be outputted, so that the output of two sequential circuit signals can be controlled concurrently. The utility model has the advantages of simple circuit structure, and convenient installation and operation, and also has the advantages that two IC card sequence circuits can be read and written simultaneously, and the equipment utilization rate can be enhanced.
