[0002]

2. Description of the Related Art The prior art is disclosed in Japanese Utility Model Publication No. 52-37233.
As described in the publication, when looking into the collimating collimator provided in the telescope of the surveying instrument, a virtual image of the collimating mark is seen in the distance by the collimating lens, and this is matched with a target seen through the outer periphery of the collimating lens. Thus, the optical axis of the telescope can be set as a target.

[0003]

The collimator mark of the collimator can be seen because the surrounding area is bright, so there is an inconvenience that the collimator cannot be seen when the surveying instrument is used in a dark place or at night.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. In the embodiments shown in FIGS. 1 to 3, reference numeral 1 denotes a body of a collimator, and in the case of the embodiment, a telescope unit of a surveying machine. It is configured so that it can be mounted by screwing. Reference numeral 2 denotes a mounting screw hole. Reference numeral 3 denotes a cylindrical collimator provided with a collimating lens 4 on the eyepiece side and a collimation mark plate 5 on the object side. It is configured so that it can be seen greatly enlarged above.

Here, the collimator 3 according to the present invention includes a light emitting element such as a light emitting diode or the like which illuminates the collimation mark 6 near the collimation mark plate 5 through the collimation lens 4 so as to be clearly visible. 7 is provided. In the embodiment shown in FIGS. 1 and 2, the light emitter 7 is provided integrally on the object side of the collimation mark plate 5, and in the embodiment shown in FIGS. 3 and 4, the eyepiece side, that is, It is provided in the cylinder of the collimator 3.

Reference numeral 8 denotes a power source battery for the luminous body 7, which is shown in FIGS.
In the embodiment of the present invention, it is provided so as to be built in the case 1. Reference numeral 9 denotes a switch for turning on / off the light emission of the light emitter 7.

Incidentally, in a surveying instrument equipped with another power source, such as a total station, an electronic theodolite, or a light wave distance measuring machine, the power source battery 8 is not built in the body 1,
Of course, it is also possible to adopt a configuration in which electric power is supplied from the outside.

In the embodiment having the above configuration, when the switch 9 is turned on, the illuminant 7 emits light when supplied with power, and the collimation mark 6 is illuminated even when the periphery of the collimator 3 is dark. This means that the telescope 11 can be easily visually recognized from the collimating lens 4. For example, in FIG. 4, the telescope 11 is easily aligned by matching the collimation mark 6 with a target to be collimated by the telescope 11 of the surveying instrument 10. , Can be aimed at.

[0011]

[Effect] According to the present invention, it is attached to the telescope of the surveying instrument ,
Place the collimation mark 6 provided on the collimation mark plate 5 on the objective side on the eyepiece side.
Collimated as a distant virtual image by the collimating lens 4
4 by matching the goal visible through the outer perimeter of
Target coarse collimation collimator that sets the optical axis of the telescope as the target
Oite the device, in the vicinity of the collimating mark plate 5, the collimation
With the configuration in which the illuminant 7 for illuminating the virtual image of the mark 6 is provided, the illuminant 7 provided in the vicinity of the collimation mark plate 5 can be used even when the surveying instrument is used in a dark place or at night .
To easily collimate the virtual image of the brightly illuminated collimation mark 6.
Is Ki de to eyes visible through the outer periphery of the collimating lens 4
Since it can be easily matched with the target, it is possible to match the collimation mark to the polar star at night in astronomical survey, or to match the collimation mark to the target in a dark place such as in a tunnel. Even in a dark place, there is an effect that the collimating operation of the telescope unit can be facilitated similarly to the usual daytime observation and surveying.

The virtual image of the collimation mark 6 is illuminated.
The light emitter 7 for, if the structure provided integrally with the objective side of the collimation mark plate 5, as shown in FIG. 2, the lighting level mark 6 viewed can be performed directly, collimating lens 4 Accordingly, since the light emitting body 7 does not obstruct the optical path for collimating the collimation mark 6, the virtual image of the collimation mark 6 can be clearly collimated.

The virtual image of the collimation mark 6 is illuminated.
Collimator light emitter 7, viewed in the semi mark plate 5 of the eyepiece side for
Since the light-emitting body 7 illuminates the collimation mark 6 directly from the inside of the collimator cylinder as shown in FIG. 3 by employing a configuration provided in the collimator cylinder, the virtual image of the collimation mark 6 is clearly seen. Since the luminous body does not protrude from the cylindrical portion of the collimator, it is possible to prevent the luminous body from being damaged by a collision with another object.
