PURPOSE:To stop the automatic transfer processing of information when an operator is near the detection range of a detecting means by providing the detecting means to detect the presence/absence of the operator in a prescribed operating position and a warning tone generating means, etc. CONSTITUTION:By a command to instruct the execution of information processing from an input device 1, a CPU 5 reads and executes a correspondent arithmetic program from a memory device 2 and an arithmetic result is written to the device 2. Next, when the end of arithmetic processing is confirmed, the CPU 5 inputs a detecting signal from an infrared detecting sensor 4 and identifies an output level. When the presence of the operator is not confirmed, the CPU 5 instructs the generation of a warning tone to a buzzer 7 and activates an internal timer. In correspondence to the count end instruction of the internal timer, the CPU 5 confirms the absence of the operator based on the detecting signal from the sensor 4 and an information processed result to be stored in the device 2 is backup-stored to an auxiliary memory device 6. Accordingly, when the operator returns to the operating position with the generation of the warning tone, the automatic transfer processing of the information can be stopped. |
