ABSTRACT:
A moveable carriage bearing an optical element, such as a font segment track select mirror, is supported upon a flat elongated plateway by means of rollers mounted upon the carriage which is translated along the plateway so that the carriage assumes only a first or second discrete position after it comes to rest. A single spring is employed to cause first and second detent members to be maintained in firm contact with each other to cause the carriage to assume either a first discrete position or a second discrete position while simultaneously maintaining the carriage mounted rollers in firm contact with the plateway.
