In those second frames section 212.As shown in figure 18, each hook block 33 has a supporting part 331 upwardly extended from the backboard 20, and
One is connected to the supporting part 331 and the fixed part 332 of a T fonts is collectively forming with the supporting part 331.Refering to Figure 19, each hook
There is an area to be substantially greater than or area 421 is worn equal to the area of the fixed part 332 for apertured 42, and one wear area with this
421 connections, and area be substantially greater than or area equal to the supporting part 331 positioning area 422, the positioning for hooking apertured 42
Area 422 is extended toward the direction of same first frame section 211.
Refering to Figure 19 and Figure 20, when being intended to for the optical unit 4 to be positioned at the frame unit 2, the fixed part of each hook block 33
331 are first arranged in this wears area 421, then the optical unit 4 is moved towards the direction of the bearing of trend in contrast to those positioning areas 422
It is dynamic, those fixed parts 332 is positioned at corresponding positioning area 422, the optical unit 4 can be positioned at the frame unit 2
In accommodation space 200.And those perforation 41 of the optical unit 4, it is elongated hole in the present embodiment, moved in the optical unit 4
Those fixtures 32 can be respectively housed when dynamic, it is to avoid those fixtures 32 hinder the optics list when being arranged in those perforation 41 respectively
The movement of unit 4.Figure 17 is referred to again, and each buckling piece 31 being arranged in those second frames section 212 is fastened on corresponding fixation
Part 32, can complete the step of assembling optical unit 4.
In sum, the optics is carried out in the way of described in the first preferred embodiment of the invention to the 4th preferred embodiment
The assembling of unit 4, is not necessary to use such as screw, the closure of rivet to fix the optical unit 4 in addition, therefore be also not necessary to artificial
Judge the position that closure should be sealed, the optical unit 4 assembling easily and accurately can be positioned at the frame unit 2, therefore
Really the purpose of the present invention can be reached.
Only as described above, only presently preferred embodiments of the present invention, when the model that present invention implementation can not be limited with this
