As a result, the first gear 75 rotates integrally, and the second gear 76 that is engaged with the first gear 75 rotates in parallel with the central axis L. Therefore, the lens holder 15 integrated with the second gear 76 rotates integrally with the second gear 76, and as shown in FIG. 5(B) or FIG. 5(C), the light-transmitting hole without the lens is provided. 45 or lens 47 is located on the above-mentioned central axis L, so that the corresponding key marks M2 or M3 are presented on a screen or the like. Further, since the lens holder 15 is held in the concave portion 51A by the spring force of the coil spring 36 by the steel ball 12-200946959 38 for maintaining the structure of the throttle mechanism, the operator can recognize the steel ball 3 8 according to the feeling of the kata. It is located at the position of the recess 51 or the position where the steel ball 38 is located away from the recess 51. Therefore, whether or not the light-transmitting hole 45 is located at a position coincident with the center axis L is permeable to the above-described feeling of the kata, so that the position of the lens holder 15 can be set constantly for the presentation position of any important mark. Therefore, according to the above embodiment, the effect of being able to select different key marks can be obtained by the 0 rotation operation of the rotating member 16. Further, since the lens holder 15 is configured to rotate about the axis L 1 orthogonal to the central axis L, it is possible to provide the center axis L and the light projecting portion 58 in the case body 1 1 . The center constitutes a thinned laser indexer 10. The preferred embodiments, methods, and the like of the present invention are disclosed above, but the present invention is not limited to the above description. That is, the present invention is mainly illustrated and described with respect to specific embodiments, but the relevant embodiments can be applied to the above-described embodiments, regardless of the shape, material, and quantity, without departing from the technical scope and the scope of the present invention. Other detailed configurations are subject to various changes. Therefore, the description of the shapes, materials, and the like described above is intended to facilitate the reader's understanding of the exemplary description disclosed in the present invention. Therefore, the present invention is not limited to the description, and the shapes and materials are based on the above. The description of the component names after the exclusion of a part or all of the definitions is included in the scope of the present invention. For example, in the above embodiment, the laser indexer of the present invention is configured to form three types of key marks from -13 to 200946959, but it is sufficient to constitute the present invention when at least two types of key marks are used. Further, the shape of the rumor is not limited to the illustrated configuration, and various lenses can be employed.
