PROBLEM TO BE SOLVED: To provide an operation history recording device capable of preventing the deterioration of response due to the influence of writing from a log buffer to an external storage device. SOLUTION: When the operation state of a job application 1 for each function unit reaches a previously set state and the capacity of a log buffer 4 can no longer store a series of job applications, a monitoring part 3 informs a log data reception part 2 of the effect. When the log data reception part 2 receives the above notice, it instructs the log buffer to compulsively write the stored content in an external storage device 5. The log buffer 4 temporarily stores log data sent from the log data reception part 2. When a compulsory write instruction from the log data reception part 2 is inputted, the stored content is transmitted to the external storage device 5. |
