GAP-ADJUSTING FILM SHEET AND LINEAR-ENCODER GAP-ADJUSTMENT METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/128976
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide the following: a low-cost gap-adjusting film sheet that can easily and reliably adjust the gap between a sensor head and a scale and adjust the orientation of said sensor head; and a linear-encoder gap-adjustment method using said gap-adjusting film sheet. In order to do so, a gap-adjusting film sheet (31) with a low-friction layer formed on each side thereof is used. This gap-adjustment method comprises the following procedures: a first procedure in which the gap-adjusting film sheet is inserted into a gap (G) between a sensor head (12) and a scale (13); a second procedure in which the sensor head and a bracket (14) are moved in the direction of the scale and the sensor head is used to press the gap-adjusting film sheet up against the scale, thereby adjusting the gap by sandwiching the gap-adjusting film sheet between the sensor head and the scale; a third procedure in which, in the above state, the bracket is affixed to a movable unit (15); and a fourth procedure in which the gap-adjusting film sheet is pulled out of the gap.
