Shape removes masking transmission line P1.
It is intended to cause hair pattern switching to the second cause hair mode from first optical profile type key 12, it is only necessary to translate actuation plate 16, prolong
Extending portion 42 is actuated the thrust of plate 16 and draws stopper section 40 and be switched to the second position from first position, at this time stopper section 40 between
Between optical transmitting set 18 and optical receiver 20, so that part covers and forms relatively narrow transmission line P1 ', such as with second
Width, the second width is less than the first width.As shown in fig. 7, sleeve member 24 not yet pushes, elastic arm component 36 without bending deformation and
Without masking transmission line P1 '.If user pushes sleeve member 24, pushing part 38 pushes against elastic arm component 36 and generates the second deflection
The bending deformation of V2, as shown in Figure 8.Optical transport channel P1 ' has narrower range (also because moving on to adjustment part 26 of the second position
There is the second width), elastic arm component 36 can cover optical transport channel P1 ' by the second deflection V2 by a small margin, make light
Formula key 12 generates trigger signal.In other words, user can change adjustment part 26 relative to light by translation actuation plate 16
The position of detecting module 17, second causes the optical transport channel P1 ' of hair mode compared to the optical transport channel P1 of the first cause hair mode
With smaller width, deformation can cover transmission line P1 ' to 36 need of elastic arm component a little, that is, the second deflection V2 is less than
First deflection V1；Second causes under hair mode, and user gently presses keycap 30 can 12 generation trigger signal of photoluminescence formula key.This

Body schematic diagram.As shown in Figure 10, adjustment part 26 ' is located at first position, and stopper section 40 ' is not overlapped or only overlapping light slightly is detectd
The optical transport channel P2 of module 17 is surveyed, optical transmission signal P2 there can be the first width at this time.When being not affected by the extruding of pushing part 38,
Elastic arm component 36 does not have flexible deformation (solid line range as shown in the figure), will not cover transmission line P2；If pushing part 38 with
Sleeve member 24 moves down and elastic arm component 36 is driven to generate flexible deformation (dotted line range as shown in the figure), and elastic arm component 36 is via the
One deflection V1 covers optical transport channel P2, and optical profile type key 12 ' is made to generate trigger signal.In addition, the translatable adjustment of user
Part 26 ' allows adjustment part 26 ' to move on to the second position shown in Figure 11 from first position shown in Figure 10；Stopper section 40 ' is located at optical transmitting set
