Key sensing element 27 in idler wheel.
The bottom of support frame 21 and bolster 22 is individually fixed in lower case 12, and a peace is formed between support frame 21 and bolster 22
Fill space 28；Idler wheel 23 is mounted in installation space 28, is allowed to idler wheel 23 between support frame 21 and bolster 22, encoder element
26 are located at side of the bolster 22 far from idler wheel 23, make bolster 22 between idler wheel 23 and encoder element 26, and encoder element 26 is pacified
Loaded on circuit board 13 and it is electrically connected circuit board 13；Idler wheel 23 have a central axis L, idler wheel 23 adjacent to the side of support frame 21 with
A mounting portion 231 is offered centered on central axis, mounting portion 231 is a circular groove；Side of the idler wheel 23 far from mounting portion 231 is in
Mandrel is that a connecting shaft 232 is extended in axle center, and connecting shaft 232 passes through bolster 22 and connects encoder element 26, wherein encoder element 26
For an encoder, wherein encoder also can be a rotary encoder, incremental optical encoder or absolute optical encoder etc., but
No longer this is limited.
Low-frictional force bearing 24 is fixed on mounting portion 231, makes the central axis of low-frictional force bearing 24 and the center of idler wheel 23
Axis is same central axis；Low-frictional force bearing 24 includes an outer bearing 241, an inner bearing 242 and multiple rolling elements 243,
The outer surface of outer bearing 241 is fixed on the inner surface of mounting portion 231, is fixed on outer bearing 241 in idler wheel 23, outer bearing
241 are set in the outside of inner bearing 242, are arranged between outer bearing 241 and inner bearing 242 in concentric circles, slide inner bearing 242
It is connected in outer bearing 241, enabling between outer bearing 241 and inner bearing 242 has a rotation gap 244, multiple rolling members
Part 243 is equally installed in the rotation gap 244 between outer bearing 241 and inner bearing 242, wherein each rolling element 243
Respectively a ball or a roller etc. make to form one between its outer bearing 241, inner bearing 242 and multiple rolling elements 243
Rolling element bearing.
25 side of support shaft, which is worn, connects support frame 21, and the other side of support shaft 25, which is worn, to be connect inner bearing 242 and be fixed on inner bearing
In 242；Key sensing element 27 is located at side of the support frame 21 far from idler wheel 23 in idler wheel, and key sensing element 27 is installed in idler wheel
In circuit board 13 and it is electrically connected circuit board 13, is located at support frame 21 in idler wheel between key sensing element 27 and idler wheel 23, is propped up
Support axis 25 is extended with an extended segment 251 far from one end of idler wheel 23, and extended segment 251 passes through the key in idler wheel of support frame 21 and senses
Element 26 moves down key sensing element 27 in pressing roller by being able to drive extended segment 251 when pressing roller 23, in idler wheel
Key sensing element 27 is a key sensor switch.
In use, driving connecting shaft 232 to rotate by idler wheel 23, and then rotate and compile first with finger roll idler wheel 23
Symbol part 26 enables to show the effect of pulling screen up and down in display screen when scroll wheel 23.
In addition, since idler wheel 23 is equipped with low-frictional force bearing 24, and low-frictional force bearing 24 is rolling element bearing, because
, when scroll wheel 23, inner bearing 242 will not be rotated with outer bearing 241, and be set to outer bearing 241 and inner bearing for this
Multiple rolling elements 243 between 242 can be rolled with the relative motion between outer bearing 241 and inner bearing 242, to reach
The effect of the frictional force between outer bearing 241 and inner bearing 242 is reduced, and then idler wheel 23 is enabled to can reduce 23 He of idler wheel when rolling
Frictional force between support shaft 25, and reach the effect of reducing force of rolling friction, and enable user that less strength can be spent to roll
Idler wheel 23 and reach laborsaving effect, and can also make idler wheel 23 roll time increase.
Referring to figure 4., there is another embodiment sectional view of the mouse of low-frictional force roller module for the present invention；With it is upper
Embodiment is stated main difference is that low-frictional force bearing 24 is replaced as low-frictional force bearing 24b, low-frictional force bearing 24b's
The outer bearing 241b and inner bearing 242b element made of a magnetic material respectively, the inner surface and inner bearing of outer bearing 241b
The outer surface of 242b is same magnetic, so low-frictional force bearing 24b is a magnetic bearing.
Using the magnetic principle that identical charges repel each other, enable between inner bearing 242b and outer bearing 241b because the relationship of opposing magnetic force produces
Raw rotation gap 244b, can make inner bearing 242b be always held at the middle section of outer bearing 241b；Therefore when user applies
When power scroll wheel 23, enable idler wheel 23 roll drive outer bearing 241b rotation when, due to outer bearing 241b and inner bearing 242b it
Between have rotation gap 244b, can make to keep a distance between inner bearing 242b and outer bearing 241b, enable outer bearing 241b opposite
When inner bearing 242b rotation, it will not be in contact the situation of friction between outer bearing 241b and inner bearing 242b, can also make to roll
Wheel 23 and support shaft 25 achieve the effect that reduce frictional force, to reach the effect of reducing force of rolling friction, whereby in scroll wheel
Also the effect of can reach laborsaving and increase by 23 rolling time of idler wheel when 23.
Furthermore since the central axis of low-frictional force bearing 24, the central axis of 24b and connecting shaft 232 and idler wheel 23 is same
Central axis, therefore can be avoided when scroll wheel 23 and eccentric situation occurs, and then avoid idler wheel 23 or connecting shaft 232 and mouse
The situation of friction or collision occurs for sample body 10, to ensure that idler wheel 23 can be rolled smoothly.
According to above description it is found that first, rolling is reduced to reach in low-frictional force bearing 24,24b are arranged in idler wheel 23
Frictional force between wheel 23 and support shaft 25, enables user that can spend less strength scroll wheel 23 and reach labour-saving function
Effect, and the time that idler wheel 23 can also be made to roll increases；Second, due to low-frictional force bearing 24,24b and connecting shaft 232
The central axis of central axis and idler wheel 23 is same central axis, can avoid that eccentric situation occurs when idler wheel 23 rolls, and true
Protecting idler wheel 23 can smoothly roll.
The foregoing is merely presently preferred embodiments of the present invention, the protection model of the claims being not intended to limit the invention
It encloses, therefore all other without departing from the lower equivalent change or modification completed of spirit disclosed in this invention, is intended to be limited solely by this hair
In the protection scope of bright claims.
