摘要： PURPOSE:To simply detect the operational malfunction of the pulse motor and to improve the reliability of a control system by monitoring the momentum of a pulse motor indicated by a drive circuit by counter means. CONSTITUTION:Assume that 100 of phase changing timing signal pulses 10 are fed and thereafter 100 of phase changing timing signal pulses 10 are fed in reverse direction to move a type head 5 first rightward and then reverse direction thereto. The counted value of the momentum counter 19 for counting the phase changing timing signals becomes 200 when the pulse motor 1 operates normally. If the pulse motor 1 malfunctions owing to hunting or the like to move only to the position B, the counted value of the counter 19 becomes 195 when returned to the reference position. In this manner, the malfunction can be detected from the counted value of the counter 19 when the reference position reset of the head 5 is detected by a reference position detector 8.

摘要： PURPOSE:To holds the logging date when a power supply is turned off with addition of the simple hardware and with use of a program by using a cache memory as a back-up memory. CONSTITUTION:When a power supply 9 is turned off, an interruption is applied to a CPU 1 with detection 9.1 of the cut-off of the supply 9. Thus the CPU 1 carries out a power interruption program 5.2 stored in a ROM 5. The program 5.2 reads the address of the logging date 2.2 out of a main memory 2. Then the logging data is stored in a cache memory 6 and the CPU 1 stops its operation. Both the memory 6 and a cache control part 7 are backed up by a battery 8 and therefore the contents of the memory 6 and the part 7 are held even in a power cut-off state. Thus the logging data 2.2 is read out of the memory 6 backed up by the battery 8. As a result, the logging data is backed up without using any exclusive memory to which a logging address is especially allocated.
