Description
Technical field
The invention relates to a kind of mechanical-optical setup of MousePen, but and particularly relevant for a kind of mechanical-optical setup of extended depth of field.
Background technology
" mouse " and " keyboard " is the fixing input tool that is equipped with of computing machine, and but the mode of using " pen " to write and draw with general custom has very big difference.The person can spend the suitable time to begin to learn the computing machine, and the cursor on the mouse control screen is used in study, and the position of memory base character on keyboard.Therefore there is MousePen to occur, and is widely used.
The design of the mechanical-optical setup of known MousePen follows the mechanical-optical setup of general optical mouse basically.Please refer to Fig. 1, it illustrates the mechanical-optical setup synoptic diagram of known optical mouse 10.Light source 18 sees through as getting on the working top 20 after the effects such as catoptron 14 and spherical lens 16 as the incident light that light emitting diode sent, and its reflected light can be sent to inductor 12 through lens 22.
Because the mechanical-optical setup of optical mouse 10 is limit,, lens 22 short as lens 22 focal lengths arrive the distance of working top 20, the factors such as distance that inductor 12 arrives lens 22, make that the field depth of lens 22 is little.Thus, optical mouse 10 can only be attached on the working top 20 and use, and when optical mouse 10 is lifted away from working top 20, then can't use.
Adopt the MousePen of similar mechanical-optical setup also to have the too small shortcoming of the depth of field.When the user uses MousePen when using the mode of " pen ", for example MousePen is lifted away from a little desktop or when tilting with respect to desktop, MousePen can can't be suitable for because of sensing is bad.In other words, the user must support desktop with MousePen, and only can could use MousePen under restrictions such as specific angle, uses MousePen and can't continue to use the user with the custom of " pen ".The inconvenience that so not only causes the user to use also increases the person's that begins to learn the computing machine difficulty of learning degree.
On the other hand, because the external form of MousePen makes that its inner installing space is comparatively long and narrow, therefore known MousePen partly is provided with its capture away from working top usually, and its illumination section is provided with next-door neighbour's working top, with as in response to.Yet capture partly is provided with away from working top, makes light path elongated, causes light-inletting quantity to descend.Moreover the light source of illumination such as light emitting diode be excessively near working top, is subjected to the light emitting diode near-field effect easily and produces blackening.
Please refer to Fig. 2, it illustrates the structural representation of known luminescence diode 30.Light emitting diode 30 includes in order to luminous chip 32, and the bottom of chip 32 electrically connects negative electrode 38, and the top of chip 32 sees through weld pad 34 and lead 36 electrically connects anode 39.Because weld pad 34 is not luminous and can't printing opacity, therefore can there be a blackening (blind spot) in the middle section of the hot spot that is sent when chip 32.
When light emitting diode was applied to MousePen, light emitting diode was the closer to working top, and the phenomenon of blackening is obvious more.The light that so not only makes light emitting diode send is inhomogeneous, and the position of blackening is usually located on the position of desiring pick-up image in the working top, makes the light-inletting quantity deficiency.
In sum, the mechanical-optical setup of known MousePen has the shortcoming of depth of field deficiency and light-inletting quantity deficiency.In view of this, need a kind of new MousePen, its depth of field that has in a big way for example is lifted away from MousePen desktop or situation such as the various angles that tilt with respect to desktop a little to be applicable to, it also can improve light-inletting quantity.
