摘要

PURPOSE:To increase the using efficiency of a mailbox, by giving a collation between the writing and reading personal keys while storing both the telegram addressed to a specified private person and the general telegrams into the same mailbox and then selecting and reading the telegram to the specified private person. CONSTITUTION:Both the telegram addressed to a specified private person and the general telegrams are stored in the mailbox 2. When the personal telegram reading request arrives at the data network from the terminal, the reading personal key is collated with the reading personal key which is already registered in the personal key register table 3 through the personal key register checking circuit 4. And when a coincidence is obtained between both, the specified personal telegram in the box 2 is selected and then delivered through the reading route 23.
