上海有线电厂生产的ZSQ型传真机只有一种转速——120转/分,从而限制了该机的用途。目前,各地都在进行MOS预报的推广工作,日本发送的周、月预报传真图也就为大家所重视,但由于这两张图通常采用60转/分发送,不得不改用由电化学纸记录的17型传真机接收。不过电化学纸又存在纸价昂贵,且不易长期保存等缺点,以致接收后一般还要描出这两张图纸,给工作带来很多不便,也影响了时效。 我台对ZSQ-1B型作了改装,使其具有
ZSQ fax machines manufactured by Shanghai Cable Plant have only one speed - 120 rpm, which limits the use of this machine. At present, the promotion of MOS forecasting is being carried out all over the country. The weekly and monthly forecast fax maps sent by Japan also attach great importance to them. However, since these two maps are usually sent at 60 rpm, they have to be replaced by electrochemical paper Recorded 17-type fax machine to receive. However, electrochemical paper has the disadvantages of expensive paper price and not easy to be stored for a long time, so that the two drawings are generally drawn after receiving the paper, which brings a lot of inconvenience to the work and affects the aging. I modified the ZSQ-1B type to make it have
