PURPOSE:To eliminate easily the factor of a fault by adding a memory means to store an operating procedure. CONSTITUTION:An output signal 2 given from an operating input device 1 is sent to a CPU5 via an interface I3 and also to a RAM8 incorporating a timer in the form of an output signal 16. The RAM8 stores the pushing order (time) of keys of the device 1. When a fault occurs, a user connects an output reader S to an electronic device F and delivers an output instruction signal 14 through the deice 1 for operation of the output instruction. The interface I3 receives the signal 14 and sends an output signal 15 to the RAM8, reads out the stored operating procedure and prints out this procedure via an interface II 11. It is also effective to store the keys in the pushing order in place of the pushing order (time) in terms of the storage contents of the RAM8. |
