Front lock stage
Some of the problems with ordinary miniature stages are that they tend to have a lot of play in their movement, and the spring types tend to creak.
However, Miruc’s front lock stage, though miniature in size, has no play in its movement and is able to deliver an extremely smooth sliding action. Also, the base of the handle has a locking stopper function as standard, affording superb operability.

If the product has poor accuracy when sliding the stage from end to end with a full stroke, you may feel the following discomfort during operation. (The operation feeling varies depending on the individual)
- ■Gori
- When turning the handle, there is a rough feeling and there is no smoothness.
This often happens when meshing of the rack and pinion is too tight. - ■Mura
(Unevenness) - This is being heavy and light like wave for every stroke.
This often happens when the mesh between the rack and pinion is too weak. - ■Kishimi
（Crease） - It is a sense of incongruity that when sliding the stage to one side, it feels stuck and becomes heavy and when sliding the stage to other side, it becomes lighter.
- ■Gata
(Backlash) - This is a subtle feeling of backlash and play due to poor sliding contact of male and female dovetail.
- ■Asobi
（Play） - This is clearance between gear contact surfaces intentionally provided in the direction of motion. By suppressing this gap as much as possible, smooth sliding can be made possible without backlash.
