PROBLEM TO BE SOLVED: To reduce current consumption at the time of service interruption than heretofore by presetting the minimum resolution (M-bit) required for the service interruption and backing up only an M-bit signal by a battery. SOLUTION: In this encoder and this output method, an M-bit signal 7a in M-bit in n-bit (M<n) is stored in a built-in memory 12 that is operated by a battery 3 even when a main power supply 2 is failed and the M-bit signal 7a is converted into serial data when the main power supply 2 is turned on and outputted externally, and a Z signal 10 denoting an origin in the least significant bit in the M-bit and an incremental signal being and a 2n signal 8a are outputted externally.
