Fig. 5 is the figure that is used to illustrate FPC electrode 111 shapes of the sensing element 110 that constitutes a pressure sensor portion 100.The electrode centers that FPC electrode 111 for example has around diameter (Φ) 4mm is Vorticose electrode pattern 113, form following shape: when utilizing pressurizing member 130 (with reference to Fig. 4) pressurization, the shape that electrode can contact with pressure sensitive conductive elastic body 120 equably from electrode pattern 113 big centers.The thickness of electrode of the electrode pattern 113 of this FPC electrode 111 is the thickness that adds nickel plating, golden 3.5 μ m on copper electrode 12 μ m, promptly forms the FPC protective seam 114 with 25 μ m thickness on the electrode surface peripheral part of Φ 4mm.By this FPC protective seam 114 being configured in the electrode surface peripheral part of Φ 4mm, between FPC electrode 111 and pressure sensitive conductive elastic body 120, can guarantee certain clearance.
Fig. 6 is sensing element 110 sectional drawings of an expression pressure sensor portion 100.As shown in Figure 6, the sensing element 110 of a pressure sensor portion 100 is formed with the FPC protective seam 114 of electrode pattern 113 and encirclement electrode pattern 113 on FPC electrode 111.This FPC protective seam 114 is with first bonding part 122 and pressure sensitive conductive elastic body 120 bondings.Use PET (polyethylene terephthalate) as this FPC protective seam 114, or the superior Kapton カ プ ト Application (trade mark) of thermotolerance or low temperature resistance etc., preferably use the hardness height to be difficult for compressed material.For example using as pressure sensitive conductive elastic body 120, thickness is イ Na ス ト マ one #86 of イ Na バ go system (strain) system of 0.5mm.The bonded areas of first bonding part 122 is that the electrode pattern that is positioned at the Φ 4mm of FPC electrode 111 forms on the FPC protective seam 114 in the outside, zone.
In addition, pressure sensitive conductive elastic body 120 usefulness second bonding part 123 and over cap 121 bondings.For example using as over cap 121, thickness is the urethane rubber (hardness 70Hs) of 0.5mm.In addition, the bonded areas of this second bonding part 123 is identical with the bonded areas of first bonding part 122, just forms the outside in zone at the electrode pattern of Φ 4mm.Its result, pressure sensitive conductive elastic body 120 and over cap 121 are not bondd by bonding agent in the zone that the electrode pattern of corresponding Φ 4mm forms the zone.This zone is that emphasis is subjected to the part from the pressure of pressurizing member 130 (with reference to Fig. 4).By should the zone as non-bonded areas, for example when the pen that is subjected to pressurizing member 130 from vergence direction is pressed, the resistance part that applies lateral excursion power etc. then is freely.And, by this part is made freely, thereby can apply uniform pressure to electrode pattern 113.
Here, be not provided with over cap 121 ground with pressurizing member 130 directly with touch the situation that pressure sensitive conductive elastic body 120 contacts under, can't bear above-mentioned alternate load, on pressure sensitive conductive elastic body 120, produce the hole soon.In addition, if select hard material, then increased surface pressing, be difficult to obtain optimum sensitivity pressure sensitive conductive elastic body 120 as over cap 121.Therefore, in the present embodiment, the urethane rubber (hardness 70Hs) by adopting thickness 0.5mm is as over cap 121, can realize obtaining highly sensitive sensing element 110 by dispersive pressure suitably.In the sensing element 110 that as above forms, the component profile size of sensing pressure sensitive portion is below thickness 1.5mm.And, use the dynamic range that covers from 0 to 500gf, resistance value is more than the 40k Ω when no-load, it when load 30gf is arranged the voltage sensitive sensor of the resistance value changeable type that changes in the scope below the 120k Ω, even the alternate load of 200gf carries out also realizing keeping the high-durability sensor of its performance more than 1,000 ten thousand times.
Secondly, utilize the pressurizing member 130 of Fig. 7～Fig. 9 explanation pressure sensor portion 100.Fig. 7 is the stereographic map of expression pressurizing member 130 structures.In addition, Fig. 8 is the sectional view that longitudinally cuts off cylindric pressurizing member 130 shown in Figure 7.Also have, Fig. 9 is the sectional view along transversely cutting pressurizing member 130 shown in Figure 7.As pressurizing member 130, adopt good resin that contains the polycarbonate glass fibre of anti-permanent strain characteristic etc. as material.
When the pressurizing member 130 that present embodiment adopted has the function that keeps pen core 12, has the function that the elastic component (over cap 121 and pressure sensitive conductive elastic body 120) to sensing element 110 pressurizes.Therefore, pressurizing member 130 also can be described as retaining member.Pressurizing member (retaining member) 130 possesses: the peristome side (end) 131 with the peristome 131a that puts into pen core 12; Pressurization part side (other end) 132 with the pressurization part 132a that is provided with towards the elastic component side; And possess on the inwall pen core maintaining part 133a that is arranged between this peristome side 131 and the pressurization part side 132 and keeps pen core 12 (with reference to Fig. 8, elastic mechanism portion 133 Fig. 9).This elastic mechanism portion 133 is by the spring device at a plurality of (in the present embodiment being two) slits 136 and peristome side 131 and pressurization part side 132 formation maintenance two ends.By both sides slit 136 is set, thereby can be pressed under the state that keeps pen core 12, in the elastic mechanism portion 133 of pressurizing member 130, produce suitable elastic deformation at pen core maintaining part 133a.In addition,, by forming the smooth sphere of aforesaid radius (R) 10mm, thereby can absorb the bump of pen core 12, pressurizing member 130 is mildly contacted with over cap 121 as the pressurization part 132a of the end face of pressurization part side 132.In addition, even produce under the situation of pressing from the pen of vergence direction, by suitably disperse load also well detecting pen press.
