Abstract
A linear encoder device () includes: a synchronization signal generation unit () configured to generate a periodic synchronization signal synchronized with a movement distance when a first sensor () installed to face a linear scale () is moved along the linear scale () based on a signal output by the first sensor (); a reference signal generation unit () configured to generate a pulse signal indicating that the reference mark is detected based on a signal output by a second sensor () installed along with the first sensor (); and a reference position detection unit () configured to generate a reference position signal indicating that a reference position decided in advance is detected when the synchronization signal is changed to a predetermined value after the reference signal generation unit () generates the pulse signal.
