(horizontal angle adjusting gear)

Horizontal angle adjusting gear 25 utilizes horizontal angle limiting member 105, support 43 by adjusting main body 13 and the distance of the portion of holding up 87 of optical bench supporting frame 19 are adjusted the level angle of optical bench 23, and described horizontal angle limiting member 105 consists of with external screw 89 and the plate of growing crosswise as the horizontal angle adjustment of operating portion spring 35 for horizontal angle adjustment, head.

Below, illustrate the structures such as spring 35 and horizontal angle limiting member 105 for above-mentioned horizontal angle adjustment.

(horizontal angle adjustment spring)

With spring 35, the compression helical spring by specified length as above forms in horizontal angle adjustment, and inside has the diameter of the stationary shaft 37 that can insert main body 13.In addition, the diameter of spring 35 for horizontal angle adjustment, forms the diameter of the vertical direction of the hole 79a that grows crosswise that is greater than horizontal direction reacting force receiving portion 79, thereby can not insert the hole 79a that grows crosswise.As shown in Fig. 1, Fig. 5 and Fig. 6, horizontal angle adjustment is inserted by the stationary shaft 37 of main body 13 with spring 35, and by the horizontal direction reacting force receiving portion 79 clamping compressions of the 7a of facade portion of main body 13 and optical bench supporting frame 19.Produced like this repulsive force that optical bench supporting frame 19 is extruded to frontal.Because optical bench supporting frame 19 utilizes bolster 39, can rotate in the horizontal direction, therefore described repulsive force act as and makes optical bench supporting frame 19(optical bench 23) under overlooking, clockwise rotate.

In addition, as shown in Figure 5, because horizontal angle adjustment is arranged on the top of the bolster 39 that can support rotationally bottom side portion 19b with spring 35, therefore bolster 39 becomes fulcrum with the connecting portion of screw 85, and horizontal angle adjustment also acts in the direction (with reference to the arrow in Fig. 5) that optical bench supporting frame 19 is slightly turned forward with the repulsive force of spring 35.Because optical bench supporting frame 19 is set to rotate, thus in rotating support portion, be formed with the gap of a little, but by pressing with spring 35 direction that turns forward by horizontal angle adjustment, optical bench supporting frame 19 remains forward lean, has prevented from rocking before and after it.

In addition, even when adjusting optical axis etc. in situation, hand is encountered optical bench 23 and is produced hypsokinesis, by horizontal angle adjustment, with spring 35, optical bench supporting frame 19 is pressed turn forward direction, and optical bench 23 also can return to original position.That is, horizontal angle adjustment makes optical bench supporting frame 19 remain the posture of regulation with spring 35.Therefore, the special-purpose mechanism that prevents that optical bench supporting frame 19 front and back from rocking needn't be set, as mentioned above, even if plain washer 41 is installed between main body 13 and optical bench supporting frame 19, be provided with gap S, also can not produce and rock, and can well rotate.

(horizontal angle limiting member)

As shown in Figure 6, horizontal angle limiting member 105 is formed by the plate of growing crosswise.The central authorities of horizontal angle limiting member 105 are provided with protuberance 105a, and protuberance 105a inserts the patchhole 87a that grows crosswise and also can in the patchhole 87a that grows crosswise, move left and right.The central authorities of protuberance 105a are provided with the horizontal angle adjustment female screw 105b being threaded with external screw 89 with horizontal angle adjustment.

As shown in Figure 1, horizontal angle adjustment is arranged on the patchhole 43a the support 43 of main body 13 and is arranged on the patchhole 87a that grows crosswise in the portion of holding up 87 of optical bench supporting frame 19 from the right-hand insertion of main body 13 with external screw 89, and horizontal angle limiting member 105 is arranged on the front of external screw 89 for horizontal angle adjustment.As mentioned above, owing to utilizing horizontal direction reacting force receiving portion 79 (clockwise) rotation from right side to the left of spring 35 for horizontal angle adjustment, optical bench supporting frame 19, so the portion of holding up 87 of optical bench supporting frame 19, is pressed against on horizontal angle limiting member 105 conventionally.In addition, hold up portion 87 and form, along with from hand towards inboard, side rolls oblique state to the right.

The adjustment of the rotating water straight angle when the external screw 89, horizontal angle limiting member 105 because of the bottom side portion 19b of the butt optical bench supporting frame 19 of growing crosswise, can not rotate.More specifically, by butt as a right side part, that be positioned at bottom side portion 19b of bottom side portion 19b and the part of extending specified length towards face side, the bottom side portion 19b of the periphery joining with the portion of holding up 87, horizontal angle limiting member 105 becomes the state that can not rotate.Therefore, follow the rotation of external screw 89 for horizontal angle adjustment, horizontal angle limiting member 105 in horizontal angle adjustment with moving along screw axis direction on external screw 89.After horizontal angle limiting member 105 moves and when the distance of the support 43 of main body 13 changes, follow the portion of holding up 87 of above-mentioned change, optical bench supporting frame 19 and the distance of the support 43 of main body 13 also to change.After horizontal angle limiting member 105 moves and when the distance of the support 43 of main body 13 is dwindled, the portion of holding up 87 that is pressed against the optical bench supporting frame 19 on horizontal angle limiting member 105 also dwindles with the distance of the support 43 of main body 13.On the other hand, after horizontal angle limiting member 105 moves and when the distance of the support 43 of main body 13 expands, after utilizing spring 35 for horizontal angle adjustment, optical bench supporting frame 19 to rotate along clockwise direction, hold up portion 87 and also expand with the distance of the support 43 of main body 13.Like this, can change the angle of rotation of optical bench supporting frame 19.; the angle of rotation of optical bench supporting frame 19 is by 105 restrictions of horizontal angle limiting member; by adjusting horizontal angle external screw 89 adjustment for, adjustment horizontal angle limiting member 105 relative positions with respect to optical bench supporting frame 19, thus adjusted the angle of rotation of the horizontal direction of optical bench supporting frame 19.

Based on Figure 11, illustrate and follow rotation rotation, optical bench supporting frame 19 of external screw 89 for horizontal angle adjustment.Figure 11 is the key diagram of the relativeness of external screw 89 and horizontal angle limiting member 105 for the adjustment of explanation horizontal angle, has represented to overlook the state of external screw 89 and horizontal angle limiting member 105 for horizontal angle adjustment.

The state that Figure 11 (a) has represented to take Figure 11 (b) as benchmark, by horizontal angle adjustment with external screw 89 state to the direction rotation of unscrewing.Now, because horizontal angle limiting member 105 and the distance of the support 43 of main body 13 expand, so utilize horizontal angle adjustment, with spring 35, the horizontal direction reacting force receiving portion 79 of the part as optical bench supporting frame 19 is pressed to the power in the place ahead, optical bench supporting frame 19 in overlooking clockwise (with reference to the arrow in Figure 11 (a)) rotate.

On the other hand, the state that Figure 11 (c) has represented to take Figure 11 (b) as benchmark, by horizontal angle adjustment with external screw 89 state to the direction rotation of tightening.Now, because horizontal angle limiting member 105 and the distance of the support 43 of main body 13 diminish, by the portion of holding up 87, be pressed against on horizontal angle limiting member 105, optical bench supporting frame 19 is (with reference to the arrow in Figure 11 (c)) rotation counterclockwise in overlooking.

So, when optical bench supporting frame 19 rotates, the protuberance 105a(horizontal angle by horizontal angle limiting member 105 is external screw 89 for adjustment) in the patchhole 87a that grows crosswise, move, optical bench supporting frame 19 is smoothly rotated.

In addition, as previously mentioned, the portion of holding up 87 of optical bench supporting frame 19, the acting force applying with spring 35 by horizontal angle adjustment is pressed against on horizontal angle limiting member 105 all the time, and the face of horizontal angle limiting member 105 1 sides of the portion of holding up 87 of 105 butts of horizontal angle limiting member becomes bearing surface.There is the rubbing surface of friction force in bearing surface.The increase that is in proportion of the power of the vertical direction of friction force and rubbing surface.In the present embodiment, spring 35 application of force directions for horizontal angle adjustment, for horizontal angle adjustment is about to the direction of principal axis of spring 35 direction that optical bench supporting frame 19 is released to face side, because described application of force direction is substantially parallel with bearing surface (rubbing surface), so the power of the vertical direction of bearing surface (rubbing surface) is little.Therefore, compare the application of force direction situation vertical with bearing surface (rubbing surface), can reduce the pressing force that horizontal angle limiting member 105 is pressed the portion of holding up 87, thereby the friction force of bearing surface is limited lowly.Therefore, optical bench supporting frame 19 is smoothly rotated, just can realize horizontal angle adjustment accurately.

In addition, application of force direction is from the deviation angle of bearing surface vertical offset, more approach 90 ° and more can make pressing force reduce that the friction force of bearing surface is suppressed lowlyer, and when deviation angle is 90 ° application of force direction parallel with bearing surface, just the friction force of bearing surface can be suppressed to minimum level.Make the deviation angle of optical bench 23 when front, preferably in the more than 45 ° scope below 90 °, 70 ° of above 90 ° of following scopes are better.

(vertical angle adjusting gear)

Vertical angle adjusting gear 27 utilizes the external screw 77 for vertical angle adjustment that vertical angle adjustment is operating portion with spring 73 and head, by adjusting the spring-loaded portion 75 of optical bench supporting frame 19 and the distance of the vertical direction reacting force receiving portion 103 of optical bench 23, adjust the angle of the vertical direction of optical bench 23.

Below, illustrate above-mentioned spring 73, the vertical angle adjustment structures such as external screw 77 for vertical angle adjustment.

With spring 73, the compression helical spring by specified length forms in vertical angle adjustment, and its inside diameter can insert external screw 77 for vertical angle adjustment.In addition, vertical angle adjustment is greater than the length of minor face of the patchhole 103a of long hole shape with the diameter of spring 73.

Near the header arrangement (rear side of viewport 101a) viewport 101a of external screw 77 for vertical angle adjustment, the patchhole 103a of vertical direction reacting force receiving portion 103 is inserted and spring 73 vertical angle adjustment in top by from vertical direction reacting force receiving portion 103, vertical angle adjustment is screwed into the vertical angle adjustment female screw 75a of setting in spring-loaded portion 75 with external screw 77.

If tighten external screw 77 for vertical angle adjustment, vertical direction reacting force receiving portion 103 shortens with the distance of spring-loaded portion 75.Now, because optical bench 23 be take projection 95 and screw 97 and is rotation axis, rotates in the vertical direction, so optical bench 23 rotates into the direction (direction of hypsokinesis) of steeving, is on optical axis direction.

In addition, vertical angle adjustment by vertical direction reacting force receiving portion 103 and the 75 clamping compressions of spring-loaded portion, produces (direction of the lengthening distance of vertical direction reacting force receiving portion 103 and the spring-loaded portion 75) repulsive force that optical bench 23 is lifted to direction with spring 73.Therefore, if unscrew external screw 77 for vertical angle adjustment, utilize the repulsive force of spring, the direction (direction leaning forward) that optical bench 23 is rotated into bend down in side-looking, under optical axis direction.

The method to set up of sending light device 3 and the optic axis adjusting method of said structure are below described.

(method to set up)

As shown in figure 12, when light device 3 is sent in setting, operator need to arrive equipment delivery the setting position of eminence, during transportation, the burning vasiform orifice 45b of the interim setting unit 45 of main body 13 and main body are locked with screw 33 lockings, and main body 13 is remained on to the top (in Figure 12, arrow has been indicated the view of the part amplification that the circle on the right is surrounded) of pedestal 15.That is, main body locks with screw 33, although arranging under state for inserting the stop hole 31 of main body 13, before arranging, (till starting to adjust optical axis) is the burning vasiform orifice 45b use of inserting main body 13 bottoms.In addition, the hook axle 63 of lid 17 is hooked on to the hook 51a upper (in Figure 12, arrow has been indicated the view of the part amplification that the circle on the left side is surrounded) of pedestal 15.Like this, can hold and send light device 3 with one hand, transportation be very easy to.In addition, for main body 13 and lid 17 are locked on pedestal 15, until pedestal 15 is installed to wall, send light device 3 all to become one, even if because one hand is held construction equipment and also can be held and send light device 3 with another handgrip, so send the setting of light device 3 to become easy.And, meanwhile, can smoothly carry out next operation.

In setting position, pedestal 15 is fixed on the switch box etc. of wall side.

Then, as shown in figure 13, by the distribution from wall side 111 from distribution window 53 draw and with the connecting portion 11a wiring of base 11.Now, because main body 13 is not blocked the distribution window 53 of pedestal 15, so can easily extract the distribution 111 from wall side.And then, because main body 13 is positioned at the top of pedestal 15, so operator looks up the position that just can easily confirm connecting portion 11a from below, easily carry out wiring operation.

Then, unscrew main body and lock with screw 33, make main body 13, from pedestal 15 separates, main body 13 be moved to below.Now, due to utilization be arranged on the rear side of base 11, downwards and inner side (from inboard towards side on hand) guide surface 11b of tilting guide distribution 111, so can not produce load on distribution 111.

Then, main body is locked after head with the screw 33 rectangular portion 31a through the stop hole 31 of main body 13, by main body 13 is moved down towards below, to allow main body lock with screw 33 through narrow width part 31b, main body 13 is arranged on to (with reference to Figure 14) on pedestal 15.

So, main body locks to hold concurrently to bring into play with screw 33 main body 13 is remained on to the effect on pedestal 15 tops temporarily, and main body 13 is fixed on to the effect on pedestal 15.

(optic axis adjusting method)

Optical axis is adjusted at the above-mentioned operation that arranges to carry out afterwards.Optical axis adjustment be roughly by after optical axis L adjustment (coarse adjustment), limit is confirmed whether to obtain output, the limit of regulation and finely tunes.Below, illustrate coarse adjustment and fine setting.

(coarse adjustment)

In coarse adjustment, for limit, collimating aperture 99a, viewport 101a and catoptron 100 are confirmed the position of opposed device, and external screw 89 and external screw 77 for vertical angle adjustment for the rotating water straight angle adjustment of limit, to adjust horizontal angle and the vertical angle of optical bench 23.

As mentioned above, the angular setting of optical bench 23 is arrived, when viewport 101a observes catoptron 100, can see collimating aperture 99a, and while seeing collimating aperture 99a from viewport 101a, in collimating aperture 99a, can see opposed device.

Figure 15 has represented the position of the collimating aperture 99a seeing from viewport 101a and the opposed device that can see among collimating aperture 99a (in Figure 15 exemplified with light-receiving device 5).

First, external screw 89 and external screw 77 for vertical angle adjustment for the rotating water straight angle adjustment of viewport 101a limit observed on limit, makes opposed device via catoptron 100 and collimating aperture 99a come into view (with reference to Figure 15 (a)).

Then, as shown in Figure 15 (b), further adjust, make opposed device be positioned at the central authorities of collimating aperture 99a.As mentioned above, due to the position of collimating aperture 99a and the horizontal direction of optical axis L consistent, like this, can make the horizontal angle of optical axis L unanimous on the whole.Therefore, in the fine setting of next operation, the main vertical angle of adjusting, has alleviated homework burden.

In addition, present embodiment as mentioned above, as the head of the operating portion of external screw 77 for vertical angle adjustment, head and viewport 101a as horizontal angle adjustment with the operating portion of external screw 89, optical bench 23 is configured in the same face side (right side of optical bench 23) relatively.Therefore, operator is seeing and is carrying out the confirmation of opposed device position and the rotary manipulation by screw head by viewport 101a to carry out the operability of optical axis adjustment good.For example, the adjustment of general operation vertical angle is with external screw 77 and horizontal angle adjustment during with external screw 89, need to see the cross bore of head of screw and by the each 90-degree rotation of each screw, to adjust horizontal angle, vertical angle, and now easily operation.

In addition, vertical angle adjustment is not limited to aforesaid way with external screw 77 and horizontal angle adjustment with the configuration of external screw 89, as long as the face beyond the front and back side of the head that vertical angle adjustment is used external screw 89 with head and the horizontal angle adjustment of external screw 77 in optical bench 23, on outer peripheral face.

(fine setting)

Fine setting is that limit is used the not shown confirmations such as voltmeter to be subject to light output level, and horizontal angle and the vertical angle of optical bench 23 adjusted on limit, to obtain the output of regulation.

Now, according to operating portion in the past, the front surface in the situation that, because hand in operation blocks optical axis L, so can not carry out limit confirmation, adjust on output level limit accurately.Therefore,, by the step that repeats first operating operation portion, carries out again subsequently the confirmation of output level, adjust.

To this, according to present embodiment, send light device 3, owing to using the header arrangement of external screw 89 on right side the horizontal angle adjustment as operating portion as mentioned above, in addition use the header arrangement of external screw 77 at upside vertical angle adjustment, so operator is positioned at the right side of sending light device 3 or light-receiving device 5, by the right side from optical bench 23, or/and upside operates, in the operation of operating portion, can not block optical axis L.Therefore, can confirm output level in limit adjusting operation portion limit, workability is very good.

Finally, will rotate the lid 17 of below that the earth's axis is freely supported on pedestal 15 front cover of main body 13 and fixing, finish the adjustment of optical axis.

In above-mentioned present embodiment, comprise: the horizontal angle adjusting gear 25 of the angle of rotation of the horizontal direction of the optical axis L of adjustment optical bench 23, and the vertical angle adjusting gear 27 of the angle of rotation of the vertical direction of adjustment optical axis L, by the operating portion of horizontal angle adjusting gear 25 being configured in to side, the operating portion of vertical angle adjusting gear 27 being configured in to upper surface, thereby when these operating portions of operation, optical axis L can not contact with hand, just can effectively carry out the fine setting of optical axis adjustment.

In addition, although the position of viewport 101a is arranged on right side, in the present invention, the position of viewport 101a is not limited to this.For example, as shown in Figure 16 and Figure 17, also can be arranged on left side.Now, catoptron 100 arranges in the mode tilting to the left.In addition,, while being positioned at left side as upper observation hole 101a, viewport 101a is to arrange by the opposed mode of head of external screw 89 with head and the horizontal angle adjustment of external screw 77 with vertical angle adjustment.Therefore, while carrying out optical axis adjustment for said apparatus, operator is positioned at the left side of main body 13, by making optical axis L roundabout and rotate hand, operation of vertical angle adjustment is the head with external screw 89 with the head of external screw 77 and horizontal angle adjustment, thus can limit observes under viewport 101a, limit do not touch optical axis L state at hand and adjusts horizontal angle and vertical angle.

As mentioned above, because collimating aperture 99a is arranged on by vertical plane light-emitting component 21, optical bench 23 depth directions, when coarse adjustment, the adjustment precision of horizontal angle direction is high especially.But the position of collimating aperture 99a is not limited to described position, also can be arranged on optical bench 23 by the surface level of light-emitting component 21.Now, can improve the precision of vertical angle direction.In addition, also can in the optical bench 23 depth direction vertical planes on optical bench 23, in the surface level by light-emitting component 21 with by light-emitting component 21, respectively arrange one, amount to two collimating aperture 99a.At this moment, because collimating aperture 99a, catoptron 100 and viewport 101a arrange in groups, so need two groups.

In addition, interim setting unit 45 is provided with burns vasiform orifice 45b, and example as shown in Figure 16 and Figure 17, also can be made as the gap 45c from the lower end of interim setting unit 45 with the length of regulation.Now, by main body 13 is put down from the top of pedestal 15, and gap 45c insertion gap is arranged.

In addition, although Figure 11 has represented the example of horizontal angle adjustment with the common support 43 perpendicular to main body 13 of external screw 89, but according to the setting in the gap of patchhole 43a, follow horizontal angle adjustment with the screw of external screw 89 send into, horizontal angle limiting member 105 is by the portion of holding up 87 pushing, horizontal angle limiting member 105 with hold up portion 87 conventionally with face butt (with reference to Figure 18 (a) and (b)), and horizontal angle adjustment with external screw 89 towards changing.

In addition, as shown in Figure 19 and Figure 20, can also there is the relative posture maintaining part 88 of holding up of the portion of holding up 87 with optical bench supporting frame 19.Posture maintaining part 88 is relatively holded up portion 87, by optical bench supporting frame 19 center, is arranged, and the distance between the head of external screw 89 for posture maintaining part 88 and horizontal angle adjustment is greater than the distance between the head of external screw 89 for the portion of holding up 87 and horizontal angle adjustment.That is, posture maintaining part 88 is positioned at the end side of external screw 89 for horizontal angle adjustment.The central authorities of posture maintaining part 88 are provided with patchhole 88a, and are inserted with external screw 89 for horizontal angle adjustment.Here, the patchhole 88a of posture maintaining part 88 is the hole of growing crosswise, and the radical length of the horizontal direction of patchhole 88a, is less than the radical length of horizontal direction of the patchhole 87a that grows crosswise of the portion of holding up 87.Like this, as shown in figure 21, horizontal angle adjustment is connected to the wall that forms patchhole 88a with external screw 89, can be by horizontal angle adjustment substantially remaining necessarily towards (posture) with external screw 89.If horizontal angle adjustment with external screw 89 towards substantially certain, needn't for the adjustment of the rotating water straight angle with external screw 89, change screwdriver towards, good operability.

Can also between the portion of holding up 87 and horizontal angle limiting member 105, configure plain washer 112 as level and smooth member, so that hold up portion 87 and horizontal angle limiting member 105(protuberance 105a) indirect butt.Like this, can make horizontal angle limiting member 105 more level and smooth with respect to relatively moving of the portion of holding up 87.

In addition,, while so configuring plain washer 112, on the protuberance 105a of horizontal angle limiting member 105, can be applied with the acting force of spring 35 for horizontal angle adjustment.Like this, compare the application of force on the long side direction end of horizontal angle limiting member 105 (situation of Figure 18), the more close axle center, position applying due to acting force, so can make horizontal angle adjustment diminish by the moment of flexure of effect on external screw 89.Therefore, in horizontal angle adjustment, with external screw 89, with the Shi Buhui effect that is threaded of female screw, there is the power of biasing with the horizontal angle adjustment of horizontal angle limiting member 105, when screw is sent into, can make the action can hardening and smoothly move all the time.
