Description
本創作關於一種按鍵結構，尤指一種發光按鍵結構。The present invention relates to a button structure, and more particularly to a light button structure.
傳統鍵盤無發光功能，當環境光線不足時，除非熟習盲打，否則使用者易誤壓按鍵，產生錯誤輸入，常造成使用者輸入上困擾。因此目前已有具有發光功能的鍵盤，使得使用者於光線不足的環境中仍可精確知道按鍵位置，進行輸入。然而，光線自按鍵下方向上照射，若非經特別設計，除鍵帽可透光部位產生光亮外，光線經可透光部位界面或其他結構件表面反射，亦可能自鍵帽下緣溢出，可能干擾使用者對按鍵的辨識，尤其是當鍵帽預定部位透光度較小時，自鍵帽下緣溢出的光線則顯得相對明亮，將困擾使用者對預定部位的判讀。此外，當環境光線不足時，自鍵帽下緣溢出的光線可能對使用者而言相對刺眼，易造成使用者操作上的不舒適感。The traditional keyboard has no illumination function. When the ambient light is insufficient, unless the user is familiar with blind typing, the user may easily press the button and generate an erroneous input, which often causes trouble to the user input. Therefore, there is currently a keyboard with a light-emitting function, so that the user can accurately know the position of the button and input it in an environment with insufficient light. However, the light is irradiated upward from the bottom of the button. If it is not specially designed, the light may be transmitted through the interface of the permeable portion or the surface of other structural members, and may overflow from the lower edge of the key cap, possibly interfering. The user recognizes the button, especially when the transmittance of the predetermined portion of the keycap is small, the light overflowing from the lower edge of the keycap is relatively bright, which will plague the user's interpretation of the predetermined portion. In addition, when the ambient light is insufficient, the light that overflows from the lower edge of the keycap may be relatively glaring to the user, which may cause discomfort to the user's operation.
鑑於先前技術中的問題，本創作的目的之一在於提供一種發光按鍵結構，利用遮光件遮蔽向鍵帽下緣行進之反射光線，以減少或消除光線自鍵帽下緣溢出的可能性，以解決習知技術中光線自鍵帽下緣溢出而造成使用者操作上不便的問題。In view of the problems in the prior art, one of the purposes of the present invention is to provide a luminescent button structure that utilizes a light shielding member to shield the reflected light traveling toward the lower edge of the keycap to reduce or eliminate the possibility of light escaping from the lower edge of the keycap. The problem of the inconvenience of the user's operation caused by the overflow of the light from the lower edge of the keycap in the prior art is solved.
根據本創作之一發光按鍵結構包含一底板、一鍵帽、一發光元件及一遮光件。該鍵帽設置於該底板之上並能相對於該底板上下移動，該鍵帽具有一周圍及位於該周圍內側之一可透光部。該發光元件設置於該可透光部之下並能發射光線，該光線部分可經由該可透光部射出 該鍵帽。該遮光件設置於該鍵帽與該底板之間，用以遮蔽部分未進入該可透光部的該光線。According to one embodiment of the present invention, a light-emitting button structure comprises a bottom plate, a keycap, a light-emitting element and a light-shielding member. The key cap is disposed on the bottom plate and can move up and down relative to the bottom plate, and the key cap has a permeable portion around the inside of the periphery. The illuminating element is disposed under the permeable portion and emits light, and the ray portion is emitted through the permeable portion The key cap. The light shielding member is disposed between the keycap and the bottom plate to shield the portion of the light that does not enter the light transmissive portion.
根據本創作之另一發光按鍵結構包含一底板、一發光元件、一鍵帽及一遮光件。該發光元件，設置於該底板上並發射一光線。該鍵帽設置於該底板上並能相對於該底板上下移動，具有一第一鍵帽區段與一第二鍵帽區段，該第一鍵帽區段和該發光元件的間隔距離小於該第二鍵帽區段和該發光元件的間隔距離，該鍵帽具有一可透光部，對正於該發光元件，該光線部分可經由該可透光部射出該鍵帽。該遮光件設置於該鍵帽與該底板之間，遮蔽部分未進入該可透光部的該光線。其中該遮光件僅設置於鄰近該第一鍵帽區段處，使得該第一鍵帽區段的該鍵帽和該底板的漏光間隙小於該第二鍵帽區段的該鍵帽和該底板的漏光間隙。Another illuminating button structure according to the present invention comprises a bottom plate, a light-emitting element, a keycap and a light-shielding member. The illuminating element is disposed on the bottom plate and emits a light. The keycap is disposed on the bottom plate and movable up and down relative to the bottom plate, and has a first keycap section and a second keycap section, and the first keycap section and the light emitting component are separated by a distance smaller than the The distance between the second keycap section and the light-emitting element, the keycap has a light-transmissive portion opposite to the light-emitting element, and the light portion can exit the keycap via the light-transmitting portion. The light shielding member is disposed between the key cap and the bottom plate, and the shielding portion does not enter the light of the light transmissive portion. Wherein the light shielding member is disposed only adjacent to the first keycap segment such that a light leakage gap of the keycap and the bottom plate of the first keycap segment is smaller than the keycap and the bottom plate of the second keycap segment Light leakage gap.
藉此，本創作之發光按鍵結構之遮光件主要利用該可透光部至該鍵帽周圍間之有限的空間設置，以避免與其他結構干涉而能有效大幅抑制或消除被底表面反射的光線溢出鍵帽的可能性。此外，即使仍有部分反射的光線自該鍵帽周圍溢出，其強度已被減弱，不致對使用者於辨識按鍵或操作上造成困擾或不適。Therefore, the light-shielding member of the luminous button structure of the present invention mainly utilizes the limited space between the light-transmitting portion and the periphery of the keycap to avoid interference with other structures, thereby effectively suppressing or eliminating the light reflected by the bottom surface. The possibility of overflowing the keycap. In addition, even if there is still some partially reflected light that overflows from around the keycap, its intensity has been weakened, causing no trouble or discomfort to the user in recognizing the button or operation.

請參閱第1圖及第2圖，第1圖為根據本創作之一較佳具體實施例之發光按鍵結構1之俯視圖，第2圖為發光按鍵結構1沿第1圖中線X-X之剖面示意圖，其中為簡化圖面及說明，發光按鍵結構1於實作上通常配置的其他元件，例如彈性圓突等，均予以省略。按鍵結構1包含一底板12、一鍵帽14、一升降機構16、一發光元件18、一遮光件20及一薄膜電路板22。鍵帽14設置於底板12之上，升降機構16連接底板12與鍵帽14，使得鍵帽14能利用升降機構16以能相對於底板12上下移動；於本實施例中，升降機構16係一剪刀式升降機構，但本創作不以此為限。鍵帽14具有一周圍14a及位於周圍14a內側之一可透光部142。為簡化說明，於本實施例中，可透光部142以區塊表示，於實作上，其輪廓可為字母或其他幾何圖樣，本創作均不以此為限，原則上視發光按鍵結構1應用於何種按鍵而定，例如功能鍵，如大小寫鎖定的功能鍵。另外，可透光部142可為透明或半透明材質製作，亦可直接為鍵帽14之鏤空區域，本創作均不以此為限。薄膜電路板22設置於底板12上。發光元件18設置於可透光部142之下並能發射光線，該光線部分可經由可透光部142射出鍵帽14。於實作上，發光元件18可電連接至設置於底板12下方之一撓性電路板(未繪示於圖中)上，底板12包含一突出部122及形成於突出部122之一通孔122a，藉此，發光元件18可容置於突出部122內側，且發光元件18發射之光線可穿過通孔122a朝向可透光部142進行，但本創作不以此為限。例如，底板12得以一遮罩杯123取代前述突出部122，遮罩杯123亦與具有前述通孔122a相似結構之通孔123a，遮罩杯123設置於薄膜電路板22上(或薄膜電路板22上形成較大的鏤孔以使遮罩杯123可直接設置於底板12上)以覆蓋發光元件18使得發光元件18之出光面正對通孔122a(如第3圖所示)，同樣可使發光元件18發 射之光線可朝向可透光部142進行。遮光件20設置於鍵帽14與底板12之間，用以遮蔽部分未進入可透光部142的該光線；其中，光線以箭頭表示。Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a plan view of a light-emitting button structure 1 according to a preferred embodiment of the present invention, and FIG. 2 is a cross-sectional view of the light-emitting button structure 1 along line XX of FIG. 1 . In order to simplify the drawing and the description, other elements, such as elastic rounds, which are usually arranged in the light-emitting button structure 1 are omitted. The button structure 1 includes a bottom plate 12, a keycap 14, a lifting mechanism 16, a light emitting element 18, a light blocking member 20, and a film circuit board 22. The key cap 14 is disposed on the bottom plate 12, and the lifting mechanism 16 is connected to the bottom plate 12 and the key cap 14, so that the key cap 14 can be moved up and down relative to the bottom plate 12 by using the lifting mechanism 16; in the embodiment, the lifting mechanism 16 is a Scissor lift mechanism, but this creation is not limited to this. The keycap 14 has a periphery 14a and a permeable portion 142 located inside the periphery 14a. In order to simplify the description, in the embodiment, the light-transmitting portion 142 is represented by a block. In practice, the outline may be a letter or other geometric pattern. The present invention is not limited thereto. In principle, the light-emitting button structure is 1 Depending on which button is applied, such as a function key, such as a function key for case locking. In addition, the light transmissive portion 142 can be made of a transparent or translucent material, or can be directly used as a hollow area of the key cap 14, and the present invention is not limited thereto. The thin film circuit board 22 is disposed on the bottom plate 12. The light-emitting element 18 is disposed under the light-transmitting portion 142 and emits light, and the light portion can be emitted from the keycap 14 via the light-transmitting portion 142. In an implementation, the light-emitting element 18 can be electrically connected to a flexible circuit board (not shown) disposed under the bottom plate 12. The bottom plate 12 includes a protruding portion 122 and a through hole 122a formed in the protruding portion 122. Thereby, the light-emitting element 18 can be received inside the protrusion 122, and the light emitted by the light-emitting element 18 can pass through the through-hole 122a toward the light-permeable portion 142, but the present invention is not limited thereto. For example, the bottom plate 12 is replaced by a mask cup 123, and the mask cup 123 is also formed with a through hole 123a having a similar structure to the through hole 122a. The mask cup 123 is disposed on the film circuit board 22 (or formed on the film circuit board 22). The larger pupil is such that the mask cup 123 can be directly disposed on the bottom plate 12 to cover the light emitting element 18 such that the light emitting surface of the light emitting element 18 faces the through hole 122a (as shown in FIG. 3), and the light emitting element 18 can also be made. hair The emitted light can be directed toward the permeable portion 142. The light shielding member 20 is disposed between the keycap 14 and the bottom plate 12 for shielding the portion of the light that does not enter the light transmissive portion 142; wherein the light is indicated by an arrow.
於本實施例中，鍵帽14包含呈環形之一裙部144，鍵帽14的周圍14a即位於裙部144的下緣(或謂環形裙部下緣)，遮光件20突出設置於裙部144的下緣且實質上朝向底板12延伸。於本實施例中，遮光件20包含向底板12延伸之第一部分20a及自第一部分20a再向鍵帽14中心之方向朝向延伸之第二部分20b；整體而言，遮光件20下端實質上朝向鍵帽14中心之方向彎折延伸。原則上，遮光件20僅需突出於裙部144，向下延伸即可產生遮蔽反射光線的效果，不以本實施例為限。補充說明的是，遮光件20非裙部144的一部分，而是突出於裙部144的結構。於實作上，裙部144雖亦有遮蔽光線的效果，但本創作之遮光件20則是進一步於裙部144的下緣部分區段的突出結構，以進一步遮蔽光線，以有效大幅抑制或消除被底表面142a反射的光線溢出鍵帽14的可能性，進而解決先前技術中光線自鍵帽下緣溢出而造成使用者操作上不便的問題。於本實施例中，如第1圖所示，鍵帽14的周圍14a可分為第一鍵帽區段S11及第二鍵帽區段S12，亦即鍵帽14左下方的周圍14a屬於第一鍵帽區段S11，周圍14a其餘部分則屬於第二鍵帽區段S12。於一般情形，因第一鍵帽區段S11相對靠近可透光部142，或謂第一鍵帽區段S11和發光元件18的間隔距離d1小於第二鍵帽區段S12和發光元件18的間隔距離d2，故若無遮光件20，則鍵帽14於此處溢漏的光線強度較強，易造成使用操作上的不便。因此，本創作僅於此第一鍵帽區段S11突出設置遮光件20(或謂遮光件20設置於鄰近該第一鍵帽區段S11處)，使得底板12和第一鍵帽區段S11的漏光間隙G1小於底板12和第二鍵帽區段S12的漏光間隙G2，即可產生有效減輕或消除溢漏光線對使用者操作上影響的程度；其中，遮光件20以隱藏線繪示於第1圖中。In the present embodiment, the key cap 14 includes a skirt portion 144 having a ring shape, and the periphery 14a of the key cap 14 is located at the lower edge of the skirt portion 144 (or the lower edge of the annular skirt portion), and the light blocking member 20 is protruded from the skirt portion 144. The lower edge extends substantially toward the bottom plate 12. In the present embodiment, the light blocking member 20 includes a first portion 20a extending toward the bottom plate 12 and a second portion 20b extending from the first portion 20a toward the center of the keycap 14; overall, the lower end of the light blocking member 20 is substantially oriented The direction of the center of the keycap 14 is bent and extended. In principle, the light shielding member 20 only needs to protrude from the skirt portion 144, and the downward extension can produce an effect of shielding the reflected light, which is not limited to the embodiment. It is added that the shade 20 is not part of the skirt 144 but protrudes from the structure of the skirt 144. In practice, although the skirt portion 144 also has the effect of shielding light, the shade member 20 of the present invention is a protruding structure further in the lower edge portion of the skirt portion 144 to further shield the light to effectively suppress or substantially The possibility that the light reflected by the bottom surface 142a overflows the key cap 14 is eliminated, thereby solving the problem that the light in the prior art overflows from the lower edge of the key cap and causes inconvenience to the user. In the present embodiment, as shown in FIG. 1, the periphery 14a of the keycap 14 can be divided into a first keycap section S11 and a second keycap section S12, that is, the periphery 14a of the lower left side of the keycap 14 belongs to the first The keycap section S11, the remainder of the circumference 14a belongs to the second keycap section S12. In a general case, since the first keycap section S11 is relatively close to the light transmissive portion 142, or the distance d1 between the first keycap section S11 and the light emitting element 18 is smaller than that of the second keycap section S12 and the light emitting element 18 The spacing distance d2, if there is no shading member 20, the light intensity of the key cap 14 overflowing here is strong, which is liable to cause inconvenience in operation. Therefore, the present invention only protrudes from the first keycap section S11 by the light shielding member 20 (or the light blocking member 20 is disposed adjacent to the first keycap section S11), so that the bottom plate 12 and the first keycap section S11 The light leakage gap G1 is smaller than the light leakage gap G2 of the bottom plate 12 and the second keycap segment S12, so as to effectively reduce or eliminate the influence of the spilled light on the operation of the user; wherein the light shielding member 20 is shown by a hidden line. In the first picture.
再補充說明的是，由於遮光件20設置於可透光部142與周圍14a之間，故可減少遮光件20與其他結構的干涉；換言之，原則上，本創作可直接應用於現有習知按鍵結構中，無需變更原結構尺寸。另外，請參閱第2圖及第4圖，第4圖為發光按鍵結構1於鍵帽14按壓後之剖面示意圖。原則上，遮光件20向底板12延伸的長度越長越佳，惟於實作上需考慮遮光件20與底板12可能干涉的現象，故於本實施例中，底板12具有一退讓槽124，其上的薄膜電路板22亦對應具有一鏤空222，當鍵帽14朝向底板12移動時，遮光件20至少部分穿過鏤空222並進入退讓槽124，以避免結構干涉。It is to be noted that since the light shielding member 20 is disposed between the light transmissive portion 142 and the surrounding portion 14a, interference between the light shielding member 20 and other structures can be reduced; in other words, in principle, the creation can be directly applied to existing conventional buttons. In the structure, it is not necessary to change the original structure size. In addition, please refer to FIG. 2 and FIG. 4 , and FIG. 4 is a schematic cross-sectional view of the light-emitting button structure 1 after the key cap 14 is pressed. In principle, the length of the light-shielding member 20 extending toward the bottom plate 12 is preferably as long as the light-shielding member 20 and the bottom plate 12 may interfere with each other. Therefore, in the embodiment, the bottom plate 12 has a retreat groove 124. The thin film circuit board 22 thereon also has a cutout 222. When the keycap 14 moves toward the bottom plate 12, the light blocking member 20 at least partially passes through the hollow 222 and enters the escape groove 124 to avoid structural interference.
請參閱第5圖及第6圖，第5圖為根據本創作之另一實施例之發光按鍵結構3之俯視圖，第6圖為發光按鍵結構3沿第5圖中線Y-Y之剖面示意圖，其中為簡化圖面及說明，發光按鍵結構3於實作上通常配置的其他元件，例如彈性圓突等，均予以省略。發光按鍵結構3與發光按鍵結構1結構大致相同，故發光按鍵結構3仍沿用發光按鍵結構1之元件符號。發光按鍵結構3與發光按鍵結構1主要不同之處在於發光按鍵結構3之遮光件40鄰近可透光部142設置。於本實施例中，可透光部142之周圍可分為第一可透光部區段S21及第二可透光部區段S22，亦即可透光部142左下方的周圍屬於第一可透光部區段S21，其餘部分則屬於第二可透光部區段S22；與前述發光按鍵結構1相較，第一可透光部區段S21係位於第一鍵帽區段S11與可透光部142之間。遮光件40(於第4圖中以隱藏線繪示)僅於第一可透光部區段S21突出鍵帽14之底表面14b設置(或謂遮光件40設置於鄰近第一可透光部區段S21且鄰近第一鍵帽區段S11處且自鍵帽14之底表面14b朝向底板12延伸)；其中，於本實施例中，底表面14b與可透光部142之底表面142a共平面，但本創作不以此為限。藉此，遮光件40可更有效地遮蔽經可透光部142之底表面142a反射並以實質上遠離鍵帽14中心之方向朝外行進之部分 的光線。關於發光按鍵結構3之其他說明，請參閱發光按鍵結構1之相關說明，不另贅述。Please refer to FIG. 5 and FIG. 6 , FIG. 5 is a plan view of a light-emitting button structure 3 according to another embodiment of the present invention, and FIG. 6 is a cross-sectional view of the light-emitting button structure 3 along line YY of FIG. 5 , wherein In order to simplify the drawing and the description, other elements that are normally arranged in the light-emitting button structure 3, such as elastic rounds, etc., are omitted. The illuminating button structure 3 is substantially identical in structure to the illuminating button structure 1, so that the illuminating button structure 3 still uses the component symbols of the illuminating button structure 1. The main difference between the illuminating button structure 3 and the illuminating button structure 1 is that the illuminating member 40 of the illuminating button structure 3 is disposed adjacent to the permeable portion 142. In this embodiment, the periphery of the light transmissive portion 142 can be divided into a first light transmissive portion S21 and a second light transmissive portion S22, that is, the periphery of the lower left portion of the light transmissive portion 142 belongs to the first The permeable portion S21, the remaining portion belongs to the second permeable portion S22; compared with the illuminating button structure 1, the first permeable portion S21 is located in the first keycap portion S11 Between the light transmissive portions 142. The light blocking member 40 (shown in hidden lines in FIG. 4) is disposed only on the bottom surface 14b of the first permeable portion S21 protruding the keycap 14 (or the light blocking member 40 is disposed adjacent to the first permeable portion) The section S21 is adjacent to the first keycap section S11 and extends from the bottom surface 14b of the keycap 14 toward the bottom plate 12); wherein, in the embodiment, the bottom surface 14b is shared with the bottom surface 142a of the light permeable portion 142 Plane, but this creation is not limited to this. Thereby, the light blocking member 40 can more effectively shield the portion that is reflected by the bottom surface 142a of the light permeable portion 142 and travels outward in a direction substantially away from the center of the keycap 14. The light. For other descriptions of the light-emitting button structure 3, please refer to the related description of the light-emitting button structure 1, which will not be described again.
補充說明的是，於本實施例中，底板12同樣具有一退讓槽126，其上的薄膜電路板22亦對應具有一鏤空224，當鍵帽14朝向底板12移動時，遮光件40至少部分穿過鏤空224並進入退讓槽126，以避免結構干涉。另外，於本實施例中，因結構尺寸限制，發光按鍵結構3未設置有如前述突出部122或遮罩杯123之結構，但本創作不以此為限。In addition, in the embodiment, the bottom plate 12 also has a retreat slot 126, and the thin film circuit board 22 thereon also has a hollow 224. When the key cap 14 moves toward the bottom plate 12, the shading member 40 is at least partially worn. The hollow 224 is passed through and enters the withdrawal slot 126 to avoid structural interference. In addition, in the embodiment, the structure of the light-emitting button structure 3 is not provided with the structure of the protruding portion 122 or the mask cup 123, but the present invention is not limited thereto.
請參閱第1圖及第7圖，第7圖為根據本創作之另一實施例之發光按鍵結構5之剖面示意圖，其中為簡化圖面及說明，發光按鍵結構5於實作上通常配置的其他元件，例如彈性圓突等，均予以省略。發光按鍵結構5與發光按鍵結構1結構大致相同，故發光按鍵結構5仍沿用發光按鍵結構1之元件符號。發光按鍵結構5與發光按鍵結構1主要不同之處在於發光按鍵結構5之遮光件60鄰近周圍14a(或謂第一鍵帽區段S11)於底板12之投影(以虛線表示)突出底板12設置。於本實施例中，遮光件60係自底板12向上延伸，薄膜電路板22對應具有一鏤空226，遮光件60穿過鏤空226，但本創作不以此為限；例如，遮光件60得直接設置於薄膜電路板22上。另外，遮光件60之設置位置與遮光件20之於底板12上之投影位置大致相當或謂相當接近；換言之，實質上，遮光件60僅設置於第一鍵帽區段S11於底板12上之投影處。同樣地，遮光件60可有效地遮蔽經可透光部142之底表面142a反射並以實質上遠離鍵帽14中心之方向朝外行進之部分的光線。補充說明的是，為增加遮光件60遮光效益，於本實施例中，鍵帽14，尤其是於裙部144對應遮光件60處形成退讓槽144a(以虛線表示於第6圖中)，使得遮光件60可更突出於底板12而不致與裙部144發生結構干涉。但本創作不以此為限。Please refer to FIG. 1 and FIG. 7. FIG. 7 is a schematic cross-sectional view of a light-emitting button structure 5 according to another embodiment of the present invention. In order to simplify the drawing and description, the light-emitting button structure 5 is generally configured in practice. Other components, such as elastic rounds, etc., are omitted. The illuminating button structure 5 is substantially identical in structure to the illuminating button structure 1, so that the illuminating button structure 5 still uses the component symbols of the illuminating button structure 1. The illuminating button structure 5 is mainly different from the illuminating button structure 1 in that the illuminating member 60 of the illuminating button structure 5 is adjacent to the projection of the bottom plate 12 (shown by a broken line) adjacent to the periphery 14a (or the first keycap portion S11). . In this embodiment, the light blocking member 60 extends upward from the bottom plate 12, and the thin film circuit board 22 correspondingly has a hollow 226, and the light blocking member 60 passes through the hollow 226, but the present invention is not limited thereto; for example, the light blocking member 60 has direct It is disposed on the thin film circuit board 22. In addition, the position of the light shielding member 60 is substantially equal to or relatively close to the projection position of the light shielding member 20 on the bottom plate 12; in other words, the light shielding member 60 is disposed only on the first keycap portion S11 on the bottom plate 12. Projection. Likewise, the light blocking member 60 can effectively shield light rays that are reflected by the bottom surface 142a of the light transmissive portion 142 and travel outward in a direction substantially away from the center of the keycap 14. In addition, in order to increase the shielding effect of the light shielding member 60, in the present embodiment, the keycap 14, especially at the skirt portion 144 corresponding to the light shielding member 60, forms an escape groove 144a (shown in broken lines in FIG. 6), so that The shade 60 can protrude further from the bottom panel 12 without structural interference with the skirt 144. However, this creation is not limited to this.
如前述實施例之說明，本創作之遮光件位於可透光部與相對靠近可透光部之鍵帽周圍之間，此有助於避免遮光件與發光按鍵結構之 其他構件發生結構干涉。此外，本創作之遮光件非完整圍繞可透光部設置，而是僅於可透光部相對接近鍵帽周圍之側邊設置，換言之，於前述實施例中，遮光件20、40第一鍵帽區段S11、第一可透光部區段S21位於鍵帽14周圍14a與可透光部142之間，此亦有助於避免結構干涉的發生。簡言之，本創作利用現有發光按鍵結構的剩餘空間設置遮光件，便能有效減少被底表面反射的光線經鍵帽周圍溢出，進而效減輕或消除溢漏光線對使用者操作上影響的程度。As described in the foregoing embodiment, the shade member of the present invention is located between the permeable portion and the periphery of the keycap relatively close to the permeable portion, which helps to avoid the structure of the light-shielding member and the light-emitting button. Structural interference occurs in other components. In addition, the light-shielding member of the present invention is not completely disposed around the light-transmitting portion, but is disposed only on the side of the light-transmitting portion relatively close to the periphery of the keycap, in other words, in the foregoing embodiment, the first key of the light-shielding member 20, 40 The cap section S11 and the first permeable section S21 are located between the periphery 14a of the keycap 14 and the permeable portion 142, which also helps to avoid structural interference. In short, the present invention utilizes the remaining space of the existing illuminated button structure to provide a light-shielding member, which can effectively reduce the light reflected by the bottom surface from overflowing around the keycap, thereby reducing or eliminating the influence of the spilled light on the user's operation. .
