PROBLEM TO BE SOLVED: To provide an operation device for enabling an operator to obtain operation evaluation in a real time, and to improve the recognition of a safety operation by knowing a factor that causes the drop of the operation evaluation.SOLUTION: A handy ten key 40 communicates with a digital tachograph 10, and acquires operation evaluation information from the digital tachograph 10 (S1). When acquiring the operation evaluation information, a CPU 41 of the handy ten key 40 stores it in a flash ROM 45 (S2), and displays the operation evaluation information at a display section (LCD) 44 (S3). The CPU 41 compares the previous operation evaluation information stored in the flash ROM 45 with present operation evaluation information (S4), and when the operation evaluation is dropping, performs notification processing of displaying the warning screen of safety operation evaluation on the display screen of the LCD 44 (S6). On this warning screen, a message saying that "quick start has exceeded * times, and one more quick start causes the drop of the operation evaluation" is displayed. |
