该石英钟是“指针式”的,但没有任何机械部分,由三圈发光二极管组成钟的盘面指针,见图1。最外面一圈由V_(s1)～V_(s12)作为秒“指针”。显示方式:从0 s开始,V_(s12)1 s闪烁一次,其他11只管子都亮。V_(s12)闪烁5次后停止闪烁并保持亮。从第5 s开始V_(s1)闪烁……,V_(s1)～V_(s12)各闪烁5次后刚好是59 s。这种显示方式的最大误差不超过5 s。它们除了显示秒数外,又能作为钟面盘的“刻度”。圆心上一
The quartz clock is “pointer ”, but without any mechanical part, consists of three laps LED clock dial pointer, see Figure 1. The outermost circle from V_ (s1) ~ V_ (s12) as the second “pointer ”. Display mode: From 0 s, V_ (s12) 1 s flashes once, and the other 11 tubes are on. V_ (s12) flashes 5 times and stops blinking and remains lit. V_ (s1) flashes ... from the 5th s, and 59 s after each flashes from V_ (s1) to V_ (s12). The maximum error of this display does not exceed 5 s. In addition to displaying seconds, they can also be used as a “dial” for a clock face. Center one
