リユートエンコーダ。[Scope of claim for utility model registration] A power source for normal use, an auxiliary power source that can supply power for a short time when the power supply for normal use is stopped, a multi-pole magnetized magnetic recording medium, and a power source for normal use. A magnetoresistive element that outputs a signal according to the movement of the magnetic recording medium when power is being supplied; a magnetic bubble element that detects the absolute position of the magnetic recording medium when the power supply is stopped for normal use; and the magnetoresistive element. It is possible to count the detection signals of the magnetic bubble element and the detection signal of the magnetic bubble element, and when the power supply for normal use is stopped, the data based on the detection signal of the magnetoresistive element is transmitted to the magnetic bubble element by operating on the power supply from the auxiliary power supply. An absolute encoder comprising a counter that counts and outputs detection data of a magnetic bubble element when the normal power supply is turned on.
