Abstract

PURPOSE:To ensure an optical and simple setting for permission to enter the room by the controller person for the person wishing to enter the room through collation of the information medium the person wishing to enter the room carries. CONSTITUTION:Readers 2a-2d are provided at the entrance of room doors 1a-1d to read out the individual code recorded on the information medium the person entering the room carries. The individual code and the reader selection code read out by readers 2a-2d are distinguished by reader signal process circuit 3 to designate the address of RAM8 corresponding to the individual code. At the same time, the room entrance permission information corresponding to the designated address is written into the memory region of RAM8 for memorization via address selector circuit 7 and manual operation means 12. Thus the contents of RAM8 can be set via means 12. When the individual code which received the room entrance permission is read out by readers 2a-2d, the individual code is decided by reader selector circuit 4. Then AND gates 5a-5d are opened with locking devices 11a-11d released for a fixed time to give the room entrance permission.
