我所研制的PHJ—Ⅱ型汇票排号机的总逻辑图与Ⅰ型机的基本相同(参阅本刊1978年第四期第一页)。Ⅰ型机由于采用分立元件,电路板数量较多,接线繁杂,耗电量也大,在电路设计上也存在着一些不合理的地方,使机器抗干扰能力降低,造成计数器误动等。Ⅱ型 The total logic diagram of the PHJ-Ⅱ typed banknote serial numbering machine developed by me was basically the same as that of the type Ⅰ machine (refer to the first page of Issue 4, 1978). Ⅰ type machine due to the use of discrete components, more circuit boards, wiring complexity, power consumption is also large, circuit design there are also some irrational place, so that the ability to reduce the machine anti-interference, resulting in counter malfunction and so on. Type II
