DATA INPUT DEVICE

摘要

PURPOSE:To simplify the constitution of a data input means for an information system as a whole by using a CPU of an input means for a master device to process the input data on an input terminal of a slave device having no CPU. CONSTITUTION:The data supplied from a slave device input means 24 are fetched by a master device input means 23 and processed by a CPU 41 of the means 23. Thus the CPU 41 processes the data supplied from its own data input device 45 and the data supplied from a data input device 48 of the means 24 so that they can be transferred with a center. Therefore it is enough to provided just a single CPU 41 that can be used in common with both devices 45 and 48 when a terminal equipment is viewed from the center. This can simplify the constitution of an input means as an information system as a whole.
