請參閱第1至第3圖,第1圖為根據本發明之一實施例之一游標裝置1之示意圖,第2圖為游標裝置1之剖視圖,第3圖為游標裝置1之功能方塊圖。游標裝置1包含一裝置殼體10、一導光片12、一光源14、一電容感測線路16、一處理模組18、一保護片20及一反射片22。導光片12、光源14、電容感測線路16、處理模組18、保護片20及反射片22容置於裝置殼體10形成之容置空間102中。導光片12具有一出光面122及相對於出光面122之一底表面124。光源14設置於導光片12之一邊側,用於產生光線L1並使光線L1自該邊側射入導光片12中,於導光片12內之光線L2可自出光面122射出導光片12。於本實施例中,反射片22大致貼附於底表面124(或謂鄰接於底表面124),但本發明不以此為限,例如反射片22雖與底表面124間存有間隙,仍具有反射光線以經底表面124再返回導光片12的功效。因此,當光線L2自底表面124射出導光片12時,可被反射片22反射以再進入導光片12中,有助於光線L2自出光面122射出導光片12。電容感測線路16形成於導光片12上,其中電容感測線路16包含複數個第一電極墊16a及複數個第二電極墊16b,該複數個第一電極墊16a形成於出光面122,該複數個第二電極墊16b形成於底表面124;於實作上,該複數個第一電極墊16a及該複數個第二電極墊16b不以正對設置為限。處理模組18與電容感測線路16電連接並包含一通訊介面182,通訊介面182可為有線通訊或無線通訊的介面。保護片20覆蓋於導光片12之出光面122之上,兼具保護導光片12及電容感測線路16之該複數個第一電極墊16a之功效。於使用游標裝置1時,使用者得以手指於保護片20上觸碰,處理模組18透過電容感測線路16感測使用者的觸碰操作以經由通訊介面182發出關於此觸碰操作之信號,以供進一步利用,例如電腦主機接收此信號以作為游標控制操作,例如游標移動、點擊等。 1 to 3, FIG. 1 is a schematic view of a vernier device 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the vernier device 1, and FIG. 3 is a functional block diagram of the vernier device 1. The vernier device 1 includes a device housing 10, a light guide 12, a light source 14, a capacitive sensing circuit 16, a processing module 18, a protective sheet 20, and a reflective sheet 22. The light guide sheet 12, the light source 14, the capacitive sensing line 16, the processing module 18, the protective sheet 20 and the reflective sheet 22 are housed in the accommodating space 102 formed by the device housing 10. The light guide sheet 12 has a light exit surface 122 and a bottom surface 124 opposite to the light exit surface 122. The light source 14 is disposed on one side of the light guide sheet 12 for generating the light beam L1 and the light beam L1 is incident into the light guide sheet 12 from the side. The light beam L2 in the light guide sheet 12 can emit light from the light exit surface 122. Sheet 12. In this embodiment, the reflective sheet 22 is substantially attached to the bottom surface 124 (or adjacent to the bottom surface 124), but the invention is not limited thereto. For example, although the reflective sheet 22 has a gap with the bottom surface 124, The effect of reflecting light to return to the light guide sheet 12 via the bottom surface 124. Therefore, when the light beam L2 exits the light guide sheet 12 from the bottom surface 124, it can be reflected by the reflection sheet 22 to re-enter the light guide sheet 12, and the light beam L2 is allowed to exit the light guide sheet 12 from the light exit surface 122. The capacitive sensing circuit 16 is formed on the light guiding sheet 12, wherein the capacitive sensing circuit 16 includes a plurality of first electrode pads 16a and a plurality of second electrode pads 16b. The plurality of first electrode pads 16a are formed on the light emitting surface 122. The plurality of second electrode pads 16b are formed on the bottom surface 124. In practice, the plurality of first electrode pads 16a and the plurality of second electrode pads 16b are not limited to the opposite arrangement. The processing module 18 is electrically connected to the capacitive sensing circuit 16 and includes a communication interface 182. The communication interface 182 can be a wired communication or wireless communication interface. The protective sheet 20 covers the light-emitting surface 122 of the light guide sheet 12 and has the functions of protecting the plurality of first electrode pads 16a of the light guide sheet 12 and the capacitance sensing line 16. When the cursor device 1 is used, the user can touch the finger on the protection sheet 20. The processing module 18 senses the user's touch operation through the capacitive sensing circuit 16 to send a signal about the touch operation via the communication interface 182. For further use, for example, the host computer receives this signal as a cursor control operation, such as cursor movement, click, and the like.
補充說明的是,於本實施例中,保護片20可為透明或半透明材料製作的,光線L2自出光面122射出導光片12後,可穿過保護片20,以提供使用者光學指示。此外,電容感測線路16,尤其是該複數個第一電極墊16a,可為透明的,便於光線L2自出光面122射出導光片12。於實作上,電容感測線路16得以印刷方式將導電高分子、奈米銀或奈米碳管形成於導光片12上,或是以濺鍍方式將氧化銦錫(ITO)形成於導光片12上。此外,於本實施例中,反射片22用於反射自底表面124射出之光線L2以使絕大部的光線L2能回到導光片12中,但本發明不以此為限。例如,在不考慮光線L2自出光面122射出導光片12之效率時,反射片22亦可省略。又例如,於該複數個第二電極墊16b形成於底表面124後,再於底表面124上披覆一層反射物質,使得於導光片12中之光線L2於底表面124(即導光片12與此反射層之界面)直接反射;此時,此反射層即取代反射片22。 It should be noted that, in this embodiment, the protective sheet 20 can be made of a transparent or translucent material, and the light L2 can pass through the protective sheet 20 after the light-emitting surface 122 is emitted from the light-emitting surface 122 to provide optical indication to the user. . In addition, the capacitive sensing circuit 16, in particular the plurality of first electrode pads 16a, may be transparent to facilitate the emission of the light guide sheet 12 from the light exit surface 122 by the light L2. In practice, the capacitive sensing circuit 16 can form a conductive polymer, a nano silver or a carbon nanotube on the light guide sheet 12 by printing, or form indium tin oxide (ITO) by sputtering. On the light sheet 12. In addition, in the present embodiment, the reflective sheet 22 is used to reflect the light L2 emitted from the bottom surface 124 so that the majority of the light L2 can be returned to the light guide sheet 12, but the invention is not limited thereto. For example, the reflection sheet 22 may be omitted regardless of the efficiency with which the light ray L2 emits the light guide sheet 12 from the light-emitting surface 122. For example, after the plurality of second electrode pads 16b are formed on the bottom surface 124, the bottom surface 124 is coated with a reflective material so that the light L2 in the light guide sheet 12 is on the bottom surface 124 (ie, the light guide sheet). The interface between 12 and the reflective layer is directly reflected; at this time, the reflective layer replaces the reflective sheet 22.
另外,於實作上,導光片12可具有一光轉向結構,形成於底表面124,用以將光線L2轉向到出光面122,以增加自出光面122射出導光片12之光線L2之強度。如第4圖所示,導光片12於底表面124多處形成粗糙面24(或是鋸齒面),作為該光轉向結構;如第5圖所示,導光片12於底表面124多處形成反射材料的網點25(例如於該複數個第二電極墊16b形成於底表面124後透過印刷反射物質實現),作為該光轉向結構。粗糙面24及網點25均有助於該處光線L2自出光面122射出導光片12。於第4圖及第5圖所示之架構中,反射片22仍得設置,有助於抑制光線L2自底表面124溢失。此外,於本實施例中,以第2圖之視角以觀,光源14(例如可為但不限於成列設置於一電路板15上的複數個LED)僅於導光片12單側提供光線L1,故原則上,於導光片12內離光源14越遠之光線L2,其強度越弱,使得自出光面122射出導光片12之光線L2之強度亦是離光源14越遠越弱。因此,於第4圖及第5圖中,離光源14越遠之粗糙面24及網點25,其佔用面積均較大,以補償光線L2強度的衰減。另外,於實作上,亦得於導光片12之相對兩側均設置 光源,例如於第2圖中導光片12左側亦設置另一光源,以使導光片12內之光線L2強度可為均勻。 In addition, in practice, the light guide sheet 12 can have a light-steering structure formed on the bottom surface 124 for diverting the light L2 to the light-emitting surface 122 to increase the light L2 emitted from the light-emitting surface 122 to the light guide sheet 12. strength. As shown in FIG. 4, the light guide sheet 12 forms a rough surface 24 (or a serrated surface) at a plurality of locations on the bottom surface 124 as the light turning structure; as shown in FIG. 5, the light guide sheet 12 has more than 124 at the bottom surface 124. A dot 25 forming a reflective material (for example, realized by the printed reflective material after the plurality of second electrode pads 16b are formed on the bottom surface 124) serves as the light redirecting structure. Both the rough surface 24 and the halftone dots 25 contribute to the light ray L2 exiting the light guide sheet 12 from the light exit surface 122. In the architecture shown in Figures 4 and 5, the reflective sheet 22 is still disposed to help inhibit light L2 from escaping from the bottom surface 124. In addition, in the present embodiment, the light source 14 (for example, but not limited to a plurality of LEDs arranged in a row on a circuit board 15) can only provide light on one side of the light guide sheet 12 from the perspective of FIG. In principle, the intensity of the light L2 which is farther from the light source 14 in the light guide sheet 12 is weaker, so that the intensity of the light L2 emitted from the light-emitting surface 122 from the light guide sheet 12 is also weaker from the light source 14 . Therefore, in FIGS. 4 and 5, the rough surface 24 and the halftone point 25 which are farther from the light source 14 have a larger occupied area to compensate for the attenuation of the intensity of the light ray L2. In addition, in practice, it is also provided on opposite sides of the light guide sheet 12. For the light source, for example, another light source is disposed on the left side of the light guide sheet 12 in FIG. 2 so that the intensity of the light L2 in the light guide sheet 12 can be uniform.
請參閱第6至第8圖,第6圖為根據本發明之一實施例之一鍵盤3之示意圖,第7圖為鍵盤3之剖視圖,第8圖為鍵盤3之功能方塊圖。鍵盤3包含前述游標裝置1大部分結構,故鍵盤3仍沿用游標裝置1之元件符號,相同元件之說明及其相關變化型可直接參閱游標裝置1之相關說明,不另贅述。鍵盤3包含一裝置殼體30及容置於裝置殼體30形成之容置空間302中之導光片12、光源14、電容感測線路16、處理模組18、保護片20、反射片22、一鍵盤部32、一薄膜電路板34及複數個壓力感應器36。鍵盤部32具有複數個鍵帽322,設置於導光片12之上。薄膜電路板34包含複數個開關342,對應鍵帽322設置。該複數個壓力感應器36對應該複數個鍵帽322設置於導光片12之下,於本實施例中,該複數個壓力感應器36並且設置於一電路板37上。處理模組18並且與薄膜電路板34及該複數個壓力感應器36電連接。藉此,於使用鍵盤3時,使用者可選擇性地按壓鍵帽322以實作按鍵輸入或於鍵盤部32上滑動以實施觸碰操作。無論是按鍵輸入或是觸碰操作,處理模組18均可透過薄膜電路板34、電容感測線路16及該複數個壓力感應器36感測並根據感測信號以產生關於按鍵輸入或是觸碰操作之控制信號,經由通訊介面182發出控制信號,以供進一步利用,例如電腦主機接收此信號以作為游標控制操作,例如按鍵輸入、游標移動、點擊等。另外,於本實施例中,按鍵輸入區域(即鍵帽322分佈所佔區域)與觸控區域(即電容感測線路16分佈所佔區域)幾乎完全重疊,故鍵盤3僅需佔用一般鍵盤空間(例如桌面),即可同時提供按鍵及觸控兩種輸入方式,提升鍵盤3使用效益。 Please refer to FIG. 6 to FIG. 8. FIG. 6 is a schematic diagram of a keyboard 3 according to an embodiment of the present invention, FIG. 7 is a cross-sectional view of the keyboard 3, and FIG. 8 is a functional block diagram of the keyboard 3. The keyboard 3 includes most of the structure of the cursor device 1 described above. Therefore, the keyboard 3 still uses the component symbols of the cursor device 1. The description of the same components and related variations can be directly referred to the related description of the cursor device 1, and will not be further described. The keyboard 3 includes a device housing 30 and a light guide 12 housed in the accommodating space 302 formed by the device housing 30, a light source 14, a capacitance sensing circuit 16, a processing module 18, a protection sheet 20, and a reflection sheet 22.

The thin film circuit board 34 includes a plurality of switches 342 disposed corresponding to the key caps 322. The plurality of pressure sensors 36 are disposed under the light guide plate 12 corresponding to the plurality of pressure sensors 36. In the embodiment, the plurality of pressure sensors 36 are disposed on a circuit board 37. The processing module 18 is electrically coupled to the thin film circuit board 34 and the plurality of pressure sensors 36. Thereby, when the keyboard 3 is used, the user can selectively press the keycap 322 to implement key input or slide on the keyboard portion 32 to perform a touch operation. Whether the key input or the touch operation, the processing module 18 can sense through the thin film circuit board 34, the capacitive sensing circuit 16 and the plurality of pressure sensors 36 and generate a touch input or touch according to the sensing signal. The control signal of the touch operation sends a control signal via the communication interface 182 for further utilization. For example, the computer host receives the signal as a cursor control operation, such as key input, cursor movement, click, and the like. In addition, in the embodiment, the key input area (ie, the area occupied by the distribution of the key cap 322) and the touch area (ie, the area occupied by the capacitance sensing line 16) are almost completely overlapped, so the keyboard 3 only needs to occupy the general keyboard space. (for example, the desktop), it can provide two input modes of buttons and touches at the same time, which improves the use efficiency of the keyboard 3.
於本實施例中,鍵盤部32為一按鍵墊,使得該複數個鍵帽322連接在一起,鍵盤部32可由但不限於矽膠製作,使得鍵盤部32具有可撓性,鍵帽322可供使用者按壓。鍵帽322於本實施例中雖呈突起狀,方便使用者觸覺辨識,但本發明不以此為限;其上印有按鍵區域指示圖案之單一軟墊, 亦得作為本發明之鍵盤部。此外,於本實施例中,薄膜電路板34位於保護片20及導光片12之下,故保護片20及導光片12需具有可撓性,使得鍵帽322向下移動而擠壓到保護片20及導光片12時,保護片20及導光片12亦能配合變形,以使對應的開關342能被觸發。又於本實施例中,鍵帽322包含一突出部322a,可使開關342容易受到擠壓而觸發。另外,於本實施例中,壓力感應器36可設置以於開關342被觸發時,壓力感應器36亦能同時感測到對對應的鍵帽322的按壓,或是當鍵帽322被更深度按壓時,壓力感應器36始能感測到按壓。此均可由產品應用(例如累計按壓時間、進一步觸發其他功能)而定,不另詳述。其中,壓力感應器36自不以對應鍵帽322設置為限。 In the embodiment, the keyboard portion 32 is a button pad, so that the plurality of key caps 322 are connected together, and the keyboard portion 32 can be made of, but not limited to, silicone, so that the keyboard portion 32 has flexibility, and the key cap 322 is available for use. Press. The key cap 322 is in the form of a protrusion in the embodiment, which is convenient for the user to recognize, but the invention is not limited thereto; a single cushion with a button area indicating pattern is printed thereon. It also serves as the keyboard portion of the present invention. In addition, in the embodiment, the thin film circuit board 34 is located under the protective sheet 20 and the light guide sheet 12, so the protective sheet 20 and the light guide sheet 12 need to have flexibility, so that the key cap 322 is moved downward and squeezed. When the protection sheet 20 and the light guide sheet 12 are protected, the protection sheet 20 and the light guide sheet 12 can also be deformed so that the corresponding switch 342 can be triggered. In the present embodiment, the key cap 322 includes a protruding portion 322a that can be easily triggered by the switch 342. In addition, in the present embodiment, the pressure sensor 36 can be configured such that when the switch 342 is triggered, the pressure sensor 36 can also sense the pressing of the corresponding key cap 322 at the same time, or when the keycap 322 is deeper. When pressed, the pressure sensor 36 can initially sense the press. This can be determined by product applications (such as cumulative press time, further triggering other functions), and will not be described in detail. The pressure sensor 36 is not limited to the corresponding key cap 322.
另外,於本實施例中,鍵盤部32已完全覆蓋導光片12,故保護片20亦得省略。反射片22亦得與薄膜電路板34整合,例如於薄膜電路板34之一基板正對底表面124之表面上披覆一層反射物質,此基板即可取代反射片22。鍵盤部32整體或部分可為透明或半透明材料製作的,光線L2自出光面122射出導光片12後,可穿過鍵盤部32,以提供使用者光學指示。當鍵盤部32以單一材料製作時,得於其下表面(及/或上表面)印刷遮罩層,以僅容許部分光線L2通過。於實作上,鍵盤部32亦得以組合結構的方式實現,例如鍵盤部32本身不透光,但於第7圖中虛線框示部分,以其他透光材料取代,作為可透光部322b;此時,光線L2則僅能從可透光部322b射出鍵帽322。 In addition, in the present embodiment, the keyboard portion 32 has completely covered the light guide sheet 12, so that the protective sheet 20 is also omitted. The reflective sheet 22 is also integrated with the thin film circuit board 34. For example, a surface of the bottom surface 124 of the substrate of the thin film circuit board 34 is coated with a reflective material, and the substrate can replace the reflective sheet 22. The keyboard portion 32 may be entirely or partially made of a transparent or translucent material. After the light beam L2 exits the light guide sheet 12 from the light exit surface 122, it may pass through the keyboard portion 32 to provide an optical indication to the user. When the keyboard portion 32 is made of a single material, the mask layer is printed on its lower surface (and/or upper surface) to allow only a portion of the light ray L2 to pass. In practice, the keyboard portion 32 can also be realized in a combined manner, for example, the keyboard portion 32 itself is opaque, but the portion indicated by the dashed line in Fig. 7 is replaced by other light transmissive material as the light transmissive portion 322b; At this time, the light beam L2 can only emit the keycap 322 from the light permeable portion 322b.
於本實施例中,薄膜電路板34係主要透過反射片22的直接擠壓而觸發其上的開關342,但本發明不以此為限。請參閱第9圖,其為根據另一實施例之鍵盤之剖視圖。於此實施例中,於薄膜電路板34上,對應開關342處設置一彈性圓突35,故當鍵帽322被按壓時,彈性圓突35受到反射片22的直接擠壓而彈性變形,進而擠壓薄膜電路板34以觸發對應的開關342。於本實施例中,彈性圓突35可提供使用者按壓的反饋力,增加使用者按壓手感。 In the present embodiment, the thin film circuit board 34 is mainly triggered by the direct pressing of the reflective sheet 22 to trigger the switch 342 thereon, but the invention is not limited thereto. Please refer to FIG. 9, which is a cross-sectional view of a keyboard according to another embodiment. In this embodiment, an elastic round protrusion 35 is disposed on the corresponding circuit board 34 on the thin film circuit board 34. When the key cap 322 is pressed, the elastic circular protrusion 35 is elastically deformed by direct compression of the reflective sheet 22. The thin film circuit board 34 is extruded to trigger the corresponding switch 342. In the present embodiment, the elastic knob 35 can provide a feedback force pressed by the user to increase the user's pressing feel.
於前述游標裝置1中關於光轉向結構之說明於鍵盤3之結構中亦 有適用。例如於第10圖所示之鍵盤中,導光片12於底表面124多處形成粗糙面24(或是鋸齒面),作為該光轉向結構;於第11圖所示之鍵盤中,於底表面124多處形成反射材料的網點25(例如於該複數個第二電極墊16b形成於底表面124後透過印刷反射物質實現),作為該光轉向結構。於前述游標裝置1中,關於粗糙面24及網點25之其他說明於此亦有適用,不另贅述。 In the foregoing cursor device 1, the description of the light steering structure is also in the structure of the keyboard 3. Applicable. For example, in the keyboard shown in FIG. 10, the light guide sheet 12 forms a rough surface 24 (or a serrated surface) at a plurality of locations on the bottom surface 124 as the light turning structure; in the keyboard shown in FIG. 11, at the bottom A plurality of dots 124 forming a reflective material on the surface 124 (for example, realized by the printed reflective material after the plurality of second electrode pads 16b are formed on the bottom surface 124) serve as the light redirecting structure. In the foregoing cursor device 1, other descriptions regarding the rough surface 24 and the halftone dot 25 are also applicable here, and will not be further described.
以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
