DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to be attached to an eyepiece of an optical device such as a microscope, and has an index eyepiece having a reticle on which an index used for positioning the object to be observed is drawn. About.

[0002]

2. Description of the Related Art FIG. 9 is a structural view of an eyepiece with an index applied to a microscope. In this eyepiece, optical lenses 2, 3, and 4 are provided in an eyepiece main body 1, and a reticle lens 5 is inserted.

An index 6 such as a parenthesis or a cross is drawn on the reticle lens 5 as shown in FIG. This index 6
Is used, for example, for positioning of a photographic mask, or when measuring the length of an object to be observed, such as a micrometer-order object, it is placed right beside the object. Things. On the other hand, there is a polarizing microscope or the like using a cross index (cross), and the index used for this is used when a high-precision measurement is performed by obtaining a right angle and a parallel relationship with a rotating stage of the microscope.

When the eyepiece is attached to an eyepiece of a microscope, the eyepiece is positioned and attached. That is, the eyepiece is inserted into the eyepiece in the direction of arrow (a) as shown in FIG. 9, but the outer periphery of the eyepiece is circular and thus can be freely rotated with respect to the eyepiece. Therefore, in order to restrict this rotation, the eyepiece lens body 1 is provided with a rotation stop pin 7. That is, the rotation stop pin 7 is inserted into a cutout or the like on the eyepiece side, thereby positioning the eyepiece with respect to the eyepiece of the microscope.

Accordingly, when the eyepiece is attached, the rotation direction is determined by the rotation stopping pin 7.
For this reason, if the index 6 is deviated from the position of the rotation stop pin 7 in the directions indicated by the arrows (b) and (c) as shown in FIG. It is difficult to measure.

Therefore, the rotation stop pin 7 and the reticle lens 5
Positioning with the index 6 is performed. This positioning is performed by various methods, for example, using a suction jig 8 as shown in FIG. That is, the reticle lens 5 is suction-held by the suction jig 8, and the reticle lens 5 is rotated and positioned in this state. Thereafter, the reticle lens 5 is inserted into the eyepiece lens body 1 again and fixed.

Further, as shown in FIG. 12, a slit 9, that is, a groove for facilitating rotation inside the eyepiece is formed in the reticle lens 5, and the reticle lens 5 is rotated by the slit 9. Positioning has been done.

As a simple positioning method, as shown in FIG. 9, a reticle lens 5 is adhered to a metal frame member 10, a slit is formed in the metal frame member 10, and a driver or the like having pins set up. Thus, positioning is performed by rotating the metal frame member 10. After this positioning,
The metal frame member 10 is fixed by applying an adhesive.

[0009]

However, each of the above positioning methods has the following problems.

(1) Since the reticle lens 5 is fixed with an adhesive after the reticle lens 5 is positioned with respect to the rotation stop pin 7, the reticle lens 5 may move during this bonding, resulting in poor positioning. Becomes

(2) Since the reticle lens 5 inserted into the eyepiece lens body 1 is rotated and positioned, it is very difficult to position the reticle lens 5 with respect to the detent pin 7 outside the eyepiece lens body 1. Adjustment. For example, when the suction jig 8 is used, the reticle lens 5 may be contaminated, and the suction jig 8 becomes large. (3) To form the slit 9 in the reticle lens 5 itself,
It is difficult to process and manufacture. (4) In the case where the metal frame member 10 is used, (a) a jig is used, and the process is difficult to adjust in manufacturing. (b) Since the reticle lens 5 is fixed with an adhesive, there are many unstable factors in manufacturing, and there are many disadvantages particularly in securing fine precision. (c) Since the metal frame member 10 is provided inside the eyepiece lens body 1, the effective diameter is reduced by the thickness of the metal frame member 10.

SUMMARY OF THE INVENTION An object of the present invention is to provide an eyepiece with an index which can easily and easily position the index with respect to the rotation stop pin and can improve the positioning accuracy.
