In sum, the laser designator P of present embodiment, will be by each switch with covering C1, C2, C3, the operating portion from the downforce in the outside of framework 1 that C4 accepts the user indirectly and applied is a laser switch 51, open behind the page and close 52, opening pass 53 and mouse switch 54 before the page is installed on first substrate 5, and by a pair of support groove 18 that is formed at framework 1 place, 18 couples of two side edge part 5a that extend along the length direction of this

first substrate

5,5a supports, thus, this a pair of

support groove

18,18 as working along the mobile limiting part Z that limits of thickness direction to first substrate 5.

If adopt this form of the composition, can suitably be limited in when each

switch

51,52,53,54 is applied with aforementioned downforce, first substrate 5 moves along its thickness direction under this downforce effect, and promptly first substrate 5 rotates relative to the radial direction of framework 1 and produces offset.In other words, by by limiting part Z two

side edge part

5a, 5a of first substrate 5 being limited along the mobile of thickness direction, the electronic circuit that can prevent from effectively to be positioned on first substrate 5 produces mobile owing to the effect of downforce.And owing to no longer need as aforementioned laser designator P1 shown in Figure 8, therefore the resin component J in that the place, inside of framework 100 is provided for fixing base 500 in addition can also reduce the part count that constitutes laser designator P effectively.

And, because being arranged to insert from the insertion starting end position Z1 that inserts first substrate, 5 usefulness always, limiting part Z finishes end position Z2, so with inner installation component 4, when promptly first substrate 5 is mounted to framework 1, limiting part Z can also play the effect of guiding parts, if adopt this form of the composition, compare with laser designator P1 in the past, the assembling procedure of laser designator P is simplified.

And, because limiting part Z is the form of the composition that first substrate 5 can not be moved along thickness direction, so can carry out the location of first substrate 5 reliably along thickness direction.

And then, owing to be construed as limiting parts Z with

groove

18,18, can in needed position the position of first substrate 5 be determined by simple processing by the formed a pair of support of wall thickness that changes framework 1.More particularly, framework 1 be set at be the cylindric shape that like that have than higher intensity on one side, set as a pair of support of limiting part Z with

groove

18,18 at assigned position on one side.

In addition in this embodiment, different with laser designator P1 as shown in Figure 8 in the past, by avoiding using resin component J, especially as shown in Figure 3, the space of the below of first substrate 5 can be vacateed effectively, thereby space that second substrate 6 is received dress can be guaranteed effectively.In other words, be configured the inner space that can effectively utilize framework 1.That is,, therefore assemble most electronic units, can give various functions laser designator P by the substrate that adopts first substrate 5 and second substrate 6 etc. to be multiple structure owing to adopt the limiting part Z of present embodiment.Say if change an angle,, each parts can be received and be contained within the littler framework 1 miniaturization of realization laser designator P by using framework 1 volume inside effectively flexibly.

And, the groove of the limiting part Z of present embodiment, be not limited to the support groove 18 in being formed at framework 1, what adopt is to reduce the wall thickness of framework 1 and make the form of the composition that can not move along thickness direction as first substrate 5 of substrate, can also adopt the form of the composition as shown in Figure 6 and Figure 7.In addition, omitted the inscape except that framework 1 and substrate 50 in these figure, it only is a synoptic diagram.

If more particularly, at first, also can shown in Fig. 6 (a), on the inner face of framework 1, form each two prominent bar 1t, 1t respectively, and between these prominent bar 1t, form groove 1s, thereby substrate 50 is held on wherein.And substrate 5 also is not limited to the double-decker shown in the aforementioned embodiments, can also be as shown in the drawing, and make substrate 50 only have single layer structure.And in the occasion that adopts prominent bar 1t shown in Fig. 6 (a), limiting part Z is not limited to the form of the composition that must form continuously, can also be formed discontinuously shown in Fig. 6 (b).And then, be not limited to the form of the composition that substrate 50 can not be moved along the vertical direction, all right groove 1s and the prominent bar 1t shown in Fig. 6 (d) shown in Fig. 6 (c) is such, make the substrate 50 can not the excessive along the vertical direction mobile form of the composition, if when may be limited to the assembling miscellaneous part by the substrate that operation produced 50 the moving of operating portion along thickness direction.If adopt this form of the composition, can the position of groove 1s suitably be provided with, so that substrate 50 is set in needed position.

And then can also constitute this limiting part Z by respect to one another a pair of

re-entrant angle

1u, 1u on the inner face that is formed on framework 1 as shown in Figure 7.

If more particularly, also can be shown in Fig. 7 (a), adopt section shape to be polygon-shaped such as be the framework 1 of hexagon shape, and with between substrate 50 insertion re-entrant angle 1u respect to one another and the re-entrant angle 1u.Can also shown in Fig. 7 (b), adopt section shape to be the framework 1 of part cylindrical shape, and utilize a pair of re-entrant angle 1u respect to one another, 1u that substrate 50 is supported in addition.And then shown in Fig. 7 (c), has the framework 1 of circular outside face if adopt, and on inner face, form a pair of re-entrant angle 1u respect to one another, 1u by changing wall thickness, then can constitute limiting part Z of the present invention by substrate 50 being supported between this a pair of re-entrant angle 1u respect to one another, 1u.Like this, if utilize re-entrant angle 1u on the inner face be formed on framework 1, then can avoid effectively to the additional processing operation that limiting part Z carries out is set.

Above embodiments of the present invention are illustrated, yet the concrete form of the composition of each several part is not restricted to above-mentioned embodiment.For example, limiting part can also be arranged to, support by the side edge part of groove, and opposite side is supported by re-entrant angle to a side of substrate.

And, can also within the scope that does not break away from theme of the present invention, carry out various distortion.
