Title:
ENTERING/LEAVING PERSON COLLATING DEVICE
Document Type and Number:
Japanese Patent JP2735167
Kind Code:
B2
Abstract:
PURPOSE: To realize the collation of entering and leaving persons flexibly by employing such constitution that the authenticity discrimination reference can be automatically switched to a value set in advance corresponding to time.
CONSTITUTION: A clock means 7 sends time information to a set time detection circuit 82. The detection circuit 82 sends a selective signal to a reference number of times selection circuit 83 and a reference number of times attaching circuit 85 by a signal from a a time vs reference number of times setting circuit 81 for user when it arrives at a time zone set in advance. The circuit 83 sends the reference number of times (n) set in advance to the reference number of times attaching circuit 85 by the signal from the time vs reference number of times setting circuit 81 for user, and outputs the reference number of times (n) set at every time zone. The output binary number (m) of a coincidence number counter circuit 32 and the output binary number (n) of the reference number of times attaching circuit 85 are inputted to a number of times comparator 41, and they are compared with each other, and a comparison result is added on the authenticity discrimination 42, and truth when it is m≥n, and falsehood when it is m<n are outputted as digital authenticity discriminating signals indicated with high and low levels.
