Abstract

PURPOSE:To prevent a dishonest use beforehand and to improve the security of a system by storing the record of a collating result at the time of collating a password number and, simultaneously, displaying storing contents. CONSTITUTION:A password number PIN of a handling person from a keyboard 33 is written to an input PIN holding part 77. Next, along with a PIN read from a handling person PIN storing part 75, it is given to a comparator 86 and a PIN collation is executed. The collating result (a collating date and a frequency of inputting to a permissible inputting frequency, etc.) is written to a PIN collating record storing part 90. The writing to the storing part 90 is executed each time the collation is executed. The collation with a controller PIN to be stored to a controller PIN storing part 76 is executed in the same way, and the collating result is written to the storing part 90. The collating result of the storing part 90 is successively read and displayed on a display part 35. Consequently, by the displayed collating record, the dishonest use can be prevented beforehand.
