Description
Technical field
The present invention relates to write down the good surface material for pen-based input device of sense and use its pen-based input device.
Background technology
Usually pen-based input device is arranged on the front of various displays such as LCD, and detected contact position signal carries out the input operation of information when contacting its surface with input pen.If the use pen-based input device then can easily carry out trickle operations such as input as continuous threadlike graph such as curve and straight line with input pen, even and also can import a large amount of information on smaller drawing.Because the input operation of writing on display with input pen becomes a kind of custom easily, so the usable range of pen-based input device carries by electronic memo and so on that information terminal and multimedia machine etc. have obtained extensively and expansion rapidly.
The surfacing that uses in the pen-based input device in the past is glass plate and the plastic plate that formed hard membrane layer from the teeth outwards.But, compare with the record sense of common paper, feel non-constant for the record of surfacing.
In order to improve the record sense of surfacing, several schemes have been proposed.
For example, can enumerate the panel surface material, wherein have hard membrane layer material that on the surface of matrix material, is provided with and the bonding coat that is provided with at the matrix material back side (refer to Patent Document 1: the spy opens flat 6-No. 309990 communiques (the 2nd page and the 3rd page)) with elastic deformation.In addition, also have, form the surfacing (refer to Patent Document 2: the spy opens flat 7-No. 244552 communiques (the 2nd page)) of concavo-convex ionizing radiation curable resin system in its surface by add the particulate of acryl resin to superficial layer.In addition, the pen-based input device that possesses the transparent flexible synthetic resin with self-repairability and mar resistance in addition is with diaphragm (refer to Patent Document 3: the spy opens flat 6-No. 180628 communiques (the 2nd page)).
Since in the pen-based input device usually by on the surface of panel, describing to operate the input of the information of finishing, so by the record sense particular importance of input pen generation with input pen.This record sense can be divided into slide sense, recessed sense (elastic sensation) and these three kinds of sensations of rough sense (roughness sense), preferably can satisfy these three kinds of sensations with good equilibrium degree.The sense of wherein particularly importantly sliding, the frictional resistance on the surface of pen-based input devices such as tip that can be by measuring input pen and panel is estimated the sense of sliding.This frictional resistance can be divided into these two kinds of the static friction forces of the kinetic friction resistance of the slip sense in being equivalent to describe to operate and the slip sense when being equivalent to begin to write.It is very important controlling these two kinds of frictional resistance.In addition, when having this slip sense,, then write down sense and can become better if having the soft feel of paper as recessed sense.And then, if the rough sense having when writing on paper with pencil is then write down sense and can be become better.
But, with regard to conventional art, can not feel to estimate according to these three, therefore the record sense is insufficient.Concerning the surfacing of patent documentation 1, form by hard membrane layer owing to the most surperficial, so the sense of sliding is bad.Its surface does not possess concavo-convex (texture) as paper etc. in addition, thereby has the not enough problem of rough sense.With regard to the surfacing of patent documentation 2, though, have the not enough problem of undesirable, the recessed sense of the sense of sliding because of surface concavo-convex has rough sense.With regard to the surfacing of patent documentation 3, though because of using soft synthetic resin to have recessed sense, the sense of sliding is undesirable.Do not form texture owing on the surface in addition, so there is the not enough problem of rough sense.
Therefore, hope can be developed and can be satisfied the surfacing with good record sense of slip sense, recessed sense and these three kinds of sensations of rough sense with good equilibrium degree, but does not also have at present to occur fully satisfying the surfacing that slides and feel.
Summary of the invention
The purpose of this invention is to provide a kind of good surface material for pen-based input device of sense and its pen-based input device of use of writing down.
The inventor etc. have carried out deep research for achieving the above object, found that, when the kinetic friction coefficient of the superficial layer of surface material for pen-based input device and coefficient of static friction are all in specific scope, feel good for above-mentioned three, and the sense of sliding becomes good especially, can improve the record sense, thereby finish the present invention.
