随着大规模集成电路技术的发展,电子计算器亦得到发展——由最初的台式发展到袖珍型,由简易型发展到函数型、程控型。它以成本低廉、使用方便、性能可靠而受到人们的欢迎。不仅广泛用于人们的日常生活和生产活动中,而且在工业上亦将得到广泛应用。国外在七十年代初期曾把袖珍电子计算器作为一个部件用在仪器上,使仪器的性能和功能都有很大的改进,并具有一些新的特点。如用键盘取代了普通仪器面板上的旋转十进开关;以按键的暂短接触代替了开关拨到相应位置的扳上扳下;以予先编好的程序存
With the development of large-scale integrated circuit technology, electronic calculators have also been developed - from the initial desktop to pocket-sized, from simple to functional type, program-controlled type. It is cheap, easy to use, reliable performance and people are welcome. Not only widely used in people’s daily life and production activities, but also in industry will also be widely used. In the early 1970s, Pocket Electronic Calculator was used as a component in the instrument, which greatly improved the performance and function of the instrument and had some new features. Such as using the keyboard instead of the ordinary instrument panel on the rotary switch; short-term contact with the button instead of the switch to the corresponding position of the pull down; to pre-programmed memory
