Utility model content

【The utility model subject to be solved】

The utility model person of the utility model has discussed the hair that expression starting state is also provided in above-mentioned position detecting device The situation of optical element.Here, as light-emitting component installation position and most preferably in the upper surface of position detecting device The neighboring area (inactive area) in the region (effective coverage) of the position of indicator can be detected.This is because, it is assumed that effective During the surface setting light-emitting component in region, user's pilot guide can be interfered, if being set to the back side or side, with tactile Touch face for it is upper and by position detecting device be set to desk it is first-class in the case of, light-emitting component cannot be introduced into the visual field of user.

However, it to be actually realised that drive the multiple of touch sensor when light-emitting component is configured in inactive area Electronic unit is closely configured in the lower section of inactive area, can not obtain the space of configuration light-emitting component.

Therefore, even if one of the purpose of this utility model is that providing a kind of be not configured in the lower section of inactive area shines The space of element can also set the position detecting device of illumination region in inactive area.

【Solution for solving the problem】

The position detecting device of the utility model is the position detecting device for the position for detecting indicator, which is characterized in that There is the substrate for being configured with multiple conductors between upper side body and lower side body, multiple conductor prolongs in a first direction respectively It stretches, and to be configured at equal intervals in the second direction orthogonal with the first direction, the indicator input side of the upper side body Surface be divided into and can detect the effective coverage of the position of the indicator by multiple conductors on the substrate and match The inactive area on the periphery of the effective coverage is put, the position detecting device has institute of the configuration in the effective coverage State the light-emitting component on substrate.

It is preferred that above-mentioned position detecting device have with one end with the light-emitting component the adjacent and other end be located at it is described invalid The light conducting member that mode in region is extended.

【Utility model effect】

According to the utility model, light-emitting component is configured on the substrate for the lower section for being configured at effective coverage, uses guide-lighting structure Part projects light to the surface of inactive area, therefore even if shines on the substrate for the lower section for being configured at inactive area without configuration The space of element also can set illumination region in inactive area.

Specific embodiment

Hereinafter, with reference to attached drawing, the embodiment of the utility model is described in detail.

Fig. 1 is the figure of the structure for the position detecting device 1 for representing present embodiment.Moreover, Fig. 2 is to represent present embodiment Position detecting device 1 internal structure figure, Fig. 3 is the figure of the section for the position detecting device 1 for representing present embodiment.

Position detecting device 1 is so-called digital quantizer or tablet computer, as shown in figure 3, with upper side body 5 and under The structure of substrate 10 is configured between side body 6 and is formed.

As shown in Figure 1, the upper surface of position detecting device 1 upper surface of side body 5 (upper) be configured with effective coverage 2 and Inactive area 3.Effective coverage 2 is to be configured to detect the region of the position of indicator by aftermentioned multiple conductors 12, Form so-called touch surface.Inactive area 3 is disposed on the region on the periphery of effective coverage 2.Circuit 11 is configured in inactive area 3 Lower section.

As shown in Fig. 2, the surface configuration in substrate 10 has on x directions (first direction) extension and orthogonal with x directions Y directions (second direction) on multiple conductors 12 to be configured at equal intervals.This multiple conductor 12 is formed for position detecting device 1 Detect the touch sensor of the position of indicator.Moreover, one end configuration circuit 11 in the y directions of substrate 10.Circuit 11 plays Following function：The potential level of each conductor 12 is detected, the position of the indicator on effective coverage 2 is detected based on its result, and The position detected is reported to computer (not shown).

Light-emitting component 13 and the circuit for carrying out power supply supply to light-emitting component 13 are also configured on the surface of substrate 10 14.The position being equivalent between multiple conductors 12 in the inside of effective coverage 2 is configured in light-emitting component 13.One end of circuit 14 Circuit 11 is connected to, the other end is connected to light-emitting component 13.In effective coverage 2, circuit 14 is extended in the x direction.Electricity Road 11 plays the function of being supplied electric power by the circuit 14 to light-emitting component 13.Light-emitting component 13 is shone by the electric power.

As shown in figure 3, it is equipped with through hole 4 in upper side body 5.As shown in Figure 1, the upper end of the through hole 4 is to inactive area 3 Interior exposing.It should be noted that the inside of through hole 4 can be cavity, but transparent component can also be buried in through hole 4. Moreover, fix light conducting member 15 in the lower surface of upper side body 5.

Fig. 4 is the figure (plan view from downside) represented in the fixed light conducting member 15 in the lower surface of upper side body 5.Such as this Shown in figure, light conducting member 15 is screwed to the lower surface of upper side body 5 using 2 screws 16.

With one end, the adjacent and other end is located at the side in inactive area 3 to light conducting member 15 with the light-emitting component 13 on substrate 10 Formula is extended.The other end of light conducting member 15 include curved surface, the curved surface by the light entered from one end in light conducting member 15 to Z direction (third direction) guiding orthogonal with x directions and y directions difference, plays pass through the light projected from light-emitting component 13 as a result, The function of being projected from through hole 4 to the surface of inactive area 3.Thereby, it is possible to the light that will be projected from light-emitting component 13 in dead space It is projected outside position detecting device 1 in domain 3.That is, light-emitting component 13 can be configured in effective coverage, and set in inactive area 3 Put illumination region.

As described above, in the present embodiment, the configuration light-emitting component 13 in effective coverage 2, uses guide-lighting structure Part 15 projects light, therefore even if the sky of light-emitting component 13 is not configured in the lower section of inactive area 3 to the surface of inactive area 3 Between, also can illumination region be set in inactive area 3.

The preferred embodiment of the utility model is this concludes the description of, but the utility model is not by such embodiment party Any restriction of formula, the utility model within the scope of its spirit, can be implemented in various ways certainly.
