本発明紘天井走行うレーンにおける吊フックの昇降中心
線を光am射によって表示する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for displaying the vertical center line of a hanging hook in a lane for running on a ceiling by means of light beams.

変化するなどの不都合があ゛つた。In the conventional KSL-carrying ζ011ts device, as shown in Part 1II, the projector 7 is attached downward at an arbitrary position of the traversing truck 10, and the descending position P of the footer 2 is adjusted by adjusting the angle of the 11 points.
・Display! ! It's 5KL. However, sometimes an arbitrary intermediate position P1 on the ascent line is displayed as a spot (*-pigeon house), and in such a case, #roaring position P1 is displayed.
has the disadvantage that it is difficult to display because it exists in the air. t
The projection angle must be changed each time the display height changes.
In addition, there were many inconveniences such as the focal spot O's intensity also changed depending on the distance and distance of the display.

jl黴がある。The main feature of the present invention is to display the target position by the intersection point of the light irradiated from two positions, and furthermore, the display area is not a single point, but is arranged in a vertical direction OII, and the target position is displayed by the intersection point of the light irradiated from two positions. Configuration K of the light projection method
jl There is mold.
