设计目的SBR-4型包裹收寄机,在恢复保价费制度后,外加了一个附加器,由于原机计算板设计上的一些问题,在使用时产生了漏计费的现象,为克服这一毛病,我们于1980年底研制了SBR-4 A型包裹收寄机,该机将保价费附加器置于控制箱内;重新设计了计算板;还进行一些其它的改进工作。原机存在问题由于附加器的输出是采用按键经移位电
Design purpose SBR-4 parcel receiving and sending machine, in the restoration of the insurance fee system, plus an additional device, due to some problems on the original computer board design, resulting in the leakage of billing in the use of the phenomenon, in order to overcome this In the late 1980s, we developed the SBR-4 Type A Parcel Receiving and Sending Machine, which put the Premium Feeder in the control box, redesigned the computing pad, and made some other improvements. Problems with the original machine Because the output of the adder is shifted by key press
