FIG. 1 is a block diagram showing an embodiment of the operation recording apparatus of the present invention.
This operation recording device is disposed on a vehicle such as a truck and is operated by turning on an ignition switch.
The operation recording apparatus includes a CPU 11, a card interface 13, an internal memory 15, a closing button 17, and a data bus 19. A CPU 11, a card interface 13, and an internal memory 15 are connected to the data bus 19.

The CPU 11 receives a vehicle speed signal from a travel sensor (vehicle speed sensor) 21. The CPU 11 calculates the travel distance of the vehicle based on the speed signal.
A memory card 23 as a recording medium is inserted into and removed from the card interface 13. In the memory card 23, an ID number of an operation recording device mounted on the vehicle is recorded at the time of start-up processing. In addition, operation data such as vehicle speed, time, and travel distance are recorded.

The internal memory 15 stores past operation data, for example, for one year. This operation data is used in the event of an accident.
The end button 17 is connected to the CPU 11. When the end button 17 is pressed, the end process is performed, and writing to the memory card 23 is completed.
FIG. 2 is a flowchart for explaining the operation of the operation recording apparatus described above. The operation recording device is activated by turning on the ignition switch.

First, in step S1 to step S5, processing in a regular start-up process mode that is a regular start-up process is performed.
In step S1, it is determined whether or not the memory card 23 is inserted into the card interface 13. The memory card 23 is inserted into the card interface 13 by the vehicle driver at the start of one operation.

  If the memory card 23 is inserted, it is determined in step S2 whether or not there is an abnormality in the memory card 23. If there is an abnormality in the memory card 23, error processing is performed in step S3. By this error processing, for example, the driver is instructed to replace the memory card 23 because there is an abnormality, for example, by voice. And operation | movement of an operation recording apparatus is complete | finished.

If there is no abnormality in the memory card 23, the ID number of the operation recording device mounted on the vehicle is recorded in the memory card 23 in step S4.
Next, in step S5, recording of operation data to the memory card 23 is started. The operation data includes vehicle speed, time, travel distance, and the like.
