摘要: A tape reader system for numerical control systems including a segmented buffer memory into which characters are read from tape and stored sequentially. One address counter keeps track of ''''write'''' addresses and another counter keeps track of ''''read'''' addresses. The most significant digits of the two counters are compared to control the writing of fresh data into memory whenever the read address bears other than a selected proximity of the write address.
