Abstract: In a tag device wherein a wire 2 has a base end 21 fixed to a tag body 10 and a forward end 23 connected to the tag body 10 as releasably locked thereto, the wire 2 is provided at its forward end 23 with a lock pin 22. The tag body 10 comprises a case 1 having a pin insertion hole 13, and a latch member 3 engageable with the lock pin 22. The latch member 3 comprises a main body 31 supported inside the case 1 and a spring piece 32 provided on the main body 31. The latch member 3 prevents the thick rod portion 26 from slipping off when moved in one direction to a limit position, and allows the thick rod portion 26 to slip off when moved in the other direction to a limit position.

Abstract: The present invention provides an ingress-egress monitoring system comprising transmitting antennas 1 disposed respectively at a plurality of ingress-egress gates, tags 2 to be attached to respective persons to be checked for egress and each adapted to transmit an identification signal in response to radio waves received from the antenna 1, receivers 3 disposed respectively at the ingress-egress gates for receiving the identification signal from the tag and each operable to output a monitoring signal containing an ID code contained in the identification signal and the number of the gate of its own, and a monitor 5 connected to the receivers 3 for displaying the ID code and the gate number based on the monitoring signal output from the receiver 3. The tags 2 transmit the respective identification signals in cycles different one another.
