Embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the hand input device 10 of the embodiment of the invention comprises input pen 11, handwriting pad 12, image fetch device 13 and support 14.

Input pen 11 has penholder 111 and is installed in switch 112 on the penholder 111, infrared light supply 113 and nib 114, and infrared light supply 113 arranges near nib 114.Wherein, switch 112 is general push-button switch, and Push switch 112 can be controlled the luminous of infrared light supply 113 and extinguish.Nib 114 can stay material trace at writing paper or other body surface, and as the vestige of inkblot, ink traces or solid graphite etc., the color of material trace can be redness, green, blueness etc., the perhaps color mixture of two or more color.

Because infrared light supply 113 is near nib 114, therefore, nib 114 material traces that stay are equal to the motion track of infrared light supply 113 substantially.

Handwriting pad 12 is a flat board, is used for the material trace that carrying material trace storing media slides and stays with the nib 114 that stores input pen 11 thereon, as the writing paper 120 of present embodiment.

Switch 112 also can be press-type, this moment, it was arranged on the nib 114, and when input pen 11 contacted with handwriting pad 12, switch 112 conductings made infrared light supply 113 be used for sending infrared light, when input pen 11 left handwriting pad 12, switch 112 cut out and makes infrared light supply 113 not luminous.Adopt this kind switch can prevent that input pen 12 is in non-motion track when writing state, to reproduce the motion track of input pen 12 more accurately.

Image fetch device 13 is arranged on a side of handwriting pad 12 by support 14, and support 14 is vertically set on the handwriting pad 12, and the picked-up scope of image fetch device 13 is the surface of handwriting pad 12.Image fetch device comprises accepting unit 131 and the camera lens module 132, fixed cell 133, filter unit 134, the switch unit 135 that are arranged on the accepting unit 131.

Certainly, image fetch device 13 also can be set directly on the handwriting pad 12.

Accepting unit 131 has the first slide rail 136a and the second slide rail 136b that intersects vertically, fixed cell 133 and camera lens module 132 are positioned at the first slide rail 136a, filter unit 133 and switch unit 135 are arranged in the second slide rail 136b, and filter unit 133 can move up and down in the second slide rail 136b under the effect of switch unit 135.

Fixed cell 133 can be contained among the first slide rail 136a just, and it comprises the first fixed cell 133a and the second fixed cell 133b, and camera lens module 132 is folded between the first fixed cell 133a and the second fixed cell 133b with fixing.

Filter unit 134 comprises glass substrate 134a, is arranged on the same lip-deep infrared fileter 134b of glass substrate 134a and cutoff filter 134c.Filter unit 134 is positioned at the picture side of camera lens module 132, enters light imaging on image sensor after infrared fileter 134b or cutoff filter 134c optical filtering of camera lens module 132.Infrared fileter 134b allows infrared light to pass through by forbidding other light, thereby makes camera lens module 132 have the infrared shooting function; Cutoff filter 134c forbids that infrared light passes through to allow visible light to pass through, thereby makes camera lens module 132 have conventional visible light shoot function.

Certainly, infrared fileter 134b also can be arranged on two relative surfaces of glass substrate 134a with cutoff filter 134c and keep the two no phase mutual interference.

Switch unit 135 comprises the first anchor clamps 135a and the second anchor clamps 135b that structure is identical, and filter unit 134 is folded between the first anchor clamps 135a and the second anchor clamps 135b.The first anchor clamps 135a comprises clamping part 1351 and adjustment part 1352, clamping part 1351 has groove 1353, adjustment part 1352 is extended by clamping part 1351 and is formed, thereby the first anchor clamps 135a and the second anchor clamps 135b are oppositely arranged filter unit 134 is housed in the zone that groove 1353 limits.Stir adjustment part 1352 and make filter unit 134 in the second slide rail 136a, move up and down, thereby make infrared fileter 134b corresponding with camera lens module 132 with one of cutoff filter 134c.

When switch 112 cuts out, input pen 11 is write the material trace that stays nib 114 at writing paper 120, stirring adjustment part 1352 then makes filter unit 134 mobile so that cutoff filter 133c alignment mirror head mould group 132 adopts the camera lens module 132 with visible light shoot function to aim at handwriting pad 12 to take the formed picture of material trace in the second slide rail 136b under the drive of switch unit 135.

Stirring switching device shifter 135 makes infrared fileter 134b be positioned at the picture side of camera lens module 132, open switch 112 then so that infrared light supply 113 sends infrared light, the motion track that this moment, infrared fileter 134b cooperated camera lens module 132 can absorb infrared light supply 113 also is delivered to computer, personal digital assistant etc. so that this motion track is shown with this motion track, can also adjust switch unit 135 again and use cutoff filter 134c to cooperate camera lens modules 132 nib 114 material traces that stay to be filmed to realize the electronical record of Hard copy shelves information.

Hand input device 10 adopts input pen 11, filter unit 134 with infrared fileter 134b and cutoff filter 134c cooperates camera lens module 132, thereby realize the switching of infrared shooting function and visible light shoot function, input pen 11 has and can stay the nib 114 of material trace and near the infrared light supply 113 of nib 114 is set at writing paper 120, when so can use infrared shooting function record infrared light supply 113 motion track written contents by transform infrared optical filter 134b and cutoff filter 134c, adopt the visible light shoot function to note nib 114 in the Hard copy shelves information that writing paper 120 stays, bring convenience to the user.

Be appreciated that handwriting pad 12 also can omit or replaced by other carrying platform, as long as can make input pen 11 can write predetermined content.

In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
