Problems solved by technology

[0009] However, although the survey point can be directly indicated by the main light rays emitted by each light source 43, the Figure 5 The 3rd commonly used measuring point indicating device shown must be provided with two measuring point indicating device lenses (measuring point indicating device lens 45)
This is the reason for the increase in production costs

Embodiment Construction

[0025] Such as figure 1 with figure 2 As shown, the measuring point indicating device 1 for indicating measuring points is provided with two light emitting diodes (light sources) 3 and 4, a collimating lens 5, a light shielding plate 7 and a driving circuit 9.

[0026] The light emitting diode (LED) 3 is a red LED, and the LED 4 is a green LED. The LEDs 3 and 4 are arranged on a common horizontal plane including the optical axis 5a of the collimator lens 5, and are axisymmetric with respect to the optical axis 5a. The collimator lens 5 and the two LEDs 3 and 4 are arranged to face each other, and the optical axes 3a and 4a of the two LEDs 3 and 4 intersect each other on the back focus 5f of the collimator lens 5 on the optical axis 5a.

[0027] The collimator lens 5 is common to the two LEDs 3 and 4. That is: the light emitted from the two LEDs 3 and 4 and incident on the central part 5b of the collimator lens 5 is collimated, and can travel as a parallel beam after passing throu...

Abstract

A survey point indicating instrument, for recognizing a line of sight visually, includes a collimating lens, two light sources being positioned so that optical axes of the two light sources intersect each other on an optical axis of the collimating lens at a focal point of the collimating lens; a driving circuit for controlling light emissions of the two light sources independently from each other; and a light shield plate having a slit, and positioned between the focal point and the two light sources so that light rays emitted from each of the two light sources to travel in an area between the optical axes are allowed to pass through the slit while other light rays emitted from each of the two light sources are cut off by the light shield plate to prevent the other light rays from traveling outside the area between the optical axes.

Description

Technical field [0001] The present invention relates to an observation device, and more specifically, to a measuring point indicating device provided in the observation device, which can be used to indicate the measuring point so that the line of sight can be seen from the side of the target. Direction. Background technique [0002] image 3 Represents a schematic diagram of a commonly used measuring point indicating device (the first commonly used measuring point indicating device) for indicating measuring points. This measuring point indicating device has a translucent plate 27 with different colors, which is located at the focal point of the optical axis of the collimator lens 25. The light source 23 is arranged behind the translucent plate 27. The main light emitted from the light source 23 is diffused, passes through the translucent plate 27 as an auxiliary light, and is then collimated by the collimating lens 25, and finally reaches the target. [0003] In this kind of com...
