Inventor: HARA KENJI
IPC: G01D5/244
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To provide an encoder capable of informing of the existence of an abnormality of the encoder even when a detection object is in a low-speed state or in the stop state. SOLUTION: When the change with time of two-phase signals A, B is detected by a change detection means (an XOR gate XO1, D type flip-flops 111, 112, and an NAND gate NA1), counting is started by a counter 113.
