Title:
TARGET GRIP
Document Type and Number:
Japanese Patent JPH03170289
Kind Code:
A
Abstract:

PURPOSE: To observe and operate positioning operation and holding operation simultaneously by forming a part of a mark on a holding grip.

CONSTITUTION: When there is a shift in position around an X axis, a shift indicated by δ occurs between an outer circumferential ring 11 in a Y-axis direction and the center coordinate of a center circle 14. When there is a shift in position around the Y axis, a shift indicated by δ' occurs between the outer circumferential ring 11 in the X-axis direction and the center coordinate of the center circle 14. Therefore by correcting the shift between the centers of the center circle 14 and the outer circumferential ring 11, positioning operations around the X- and Yaxis directions are possible. In addition, operation is easy if a center of a target or the like is displayed while it overlaps with an image of a target grip 10 to be observed.
