Filed: 1981-03-31
Abstract: PURPOSE:To get rid of influence of dropout, and to record and reproduce stably, by arraying plural heads in the moving direction of a recording medium, and cascading each head through a delay element whose delay time has been prescribed specifically. CONSTITUTION:Magnetic heads H1-H5 are placed at equal intervals in the relative moving direction of a magnetic tape M, each of them is cascaded through delay elements D1-D4, and is connected to both a recording terminal R and a reproducing terminal P. Also, when a relative moving speed of the tape M and an array interval of the heads H1-H5 are denoted as (v) and L, respectively, each delay time tau of the delay elements D1-D4 is set as tau=L/v. Accordingly, recording or reproducing is executed by repeatedly adding a signal of the same time point by the number of times each corresponding to the number of the heads, therefore, even if dropout occurs in one position, recording or reproducing is executed by other heads, and the operation is stabilized.

IPC: G03G15/20
Filed: 1991-03-13
Abstract: PURPOSE:To prevent malfunction due to a noise and to improve the reliability by providing a means which continues to count regardless of the invalidation of an abnormal state after the abnormal state continues for longer than a certain time and a means which stops feeding electricity to a fixation heater for the continuance of the abnormal state. CONSTITUTION:When an overheating state detection comparator 11 enters a current suction state, a transistor(TR) 127 turns off and a capacitor 128 for clocking is charged. When the potential of the capacitor 128 rises above the inverted input voltage of the comparator 12 for clocking, a TR 14 turns on and a TR 139 turns off to cut off a relay 106, thereby stopping the power supply to a fixing heater (not shown in figure). When the potential of the capacitor 128 rises above the certain voltage, a TR 16 turns on and a TR 127 turns off to charge the capacitor 128 continuously. Once the abnormal state continues for longer than the certain time, the relay 106 is held off continuously.
