Claims

[Scope of utility model registration request]

A position detection device that uses a counter to count the signal output from a displacement detector every time the movable body is displaced by a unit amount, and detects the position of the movable body based on the count output from the counter. A backup battery is provided which is charged by the supplied power when power is supplied, and when the power is cut off, power is supplied from this battery to both the displacement detector and the counter. position detection device.
