Claims

[Scope of utility model registration request]

A position control mechanism for positioning by counting a distance measuring pulse signal indicating a moving distance of a conveying device, the mechanism comprising: a rack disposed along the moving direction of the conveying device; a pinion gear meshing with the rack; a rotary encoder that rotates with the rotation of the pinion gear and emits the distance measuring pulse signal; and a unit that holds the pinion gear and rotary encoder and is supported on the conveying device side so as to be slidable in the direction in which the pinion gear and the rack engage. 1. A position control mechanism for a conveying device, comprising: a mounting plate; and a biasing means installed between the unit mounting plate and the conveying device and biasing the pinion gear in a direction to easily engage the pinion gear.
