Abstract
A communication system is designed to exchange messages between a plurality of paging receivers each having a transmission section. One of the paging receivers transmits a question message and a plurality of answer contents to the question message to a paging receiver group constituted by the remaining paging receivers. When answer messages are returned from the paging receiver group which has received the question message and the answer contents, the paging receiver totalizes the answer messages, and displays them on a liquid crystal display panel, together with the question message.
