在维修出售机的过程中,常常需用空白邮票作试验,以调整出票的时间和出票机构的压力。但是,由于空白邮票的缺乏,给维护人员带来不少的困难。最近,我们改用电报纸条经过简单的凿孔加工后,代替空白邮票检修出售机。实践证明,凿孔纸条不但可以代替空白邮票,而且由于凿孔纸条比正式邮票纸质坚韧,用它调整出票机构效果更好。 In the process of repairing the vending machines, blank stamps are often used as a test to adjust the time for issuing tickets and the pressure on the issuers. However, due to the lack of blank stamps, many difficulties have been brought to maintenance personnel. Recently, instead of using blank stamps, we repaired vending machines instead of using simple strips of telegraph paper. Practice has proved that perforated paper not only can replace the blank stamps, but also because the perforated paper stamps tough than the official stamps, use it to adjust the ticket agencies better.
