Abstract
A working hour system corresponding to each of a number of different kinds of plural work classes is stored in the form of predetermined format in a storage section of a time recorder. A time card has a work class code expressing the work class of the person who owns the card. When the time card is inserted into the time recorder, the time recorder first reads out the work class code recorded on the time, determines the work data related to the time of acceptance of the card by arithmetic operation based on the working hour system in a storage section corresponding to the work class code, and prints the results of this arithmetic operation on the time card.
