PURPOSE:To provide a work data recorder capable of exactly evaluating the work contents of an operator by recording the counter output of a counter circuit and the clock output of a clock circuit in an IC card storage device. CONSTITUTION:The data bus 12 of a keyboard input device 10 is connected with the data bus 13 of a computer main body 11 via a control circuit 2. This data bus 13 is connected with a counter circuit 3 counting the number of depressed key of a keyboard input device 10 and the trigger terminal of the counter circuit 3 is connected with the output of an AND gate 6. The output of the AND gate 6 is connected with the trigger terminal of a clock circuit 4. The count output of the counter circuit 3 and the clock output of the clock circuit 4 are connected with the input of an IC card storage device circuit 5. Therefore, if the contents of an IC card is summed up, it is compared with the contents of the result of a work and it is verified after the work is terminated, the work efficiency of an operator can be rightly evaluated.
