Abstract

PURPOSE:To execute write and read quickly, by detecting an idle subfile, writing to the idle subfile through a buffer memory from each terminal equipment, and reading out to the terminal equipment through the buffer memory from the idle subfile. CONSTITUTION:In case when some information is accumulated in a file 5 from a terminal equipment 1-1, its information is accumulated in a buffer memory file 4. Subsequently, when an address is added to the head of the information and also a write signal is sent to a CPU7 through a signal line 3 from the terminal equipment 1-1, the CPU7 drives a subfile display device 6, and detects an idle state of the subfile. For instance, when the subfile 5 is idle, the CPU7 connects a memory A-1 and a file 5-1. As a result, the information of the terminal is accumulated in the memory A-1, and when the memory A-1 is saturated, the information is accumulated in a memory A-2 alternately, and is written in order to the subfiles 5-1, 5-2.... Aslo, when reading out, the information is read out from the memories A-1, A-2, etc. by the CPU7.
