The keypad 100 is preferably an integrally formed diaphragm and may be made of a transparent, translucent or opaque material. In one embodiment, the keypad 100 is preferably made of silicone, plastic or polymer, but is not limited thereto. In another embodiment, the keypad 100 may also have a protective coating applied to the outer surface of the keypad to increase the lifetime of the keypad 100. Moreover, depending on the design requirements, the color versatility of the appearance of the keypad 100 can also be increased by applying coatings of different colors. The keypad 100 has an upper surface 102 and a lower surface 104 opposite to the upper surface 102, and the keypad 100 defines at least one keypad 110 on its upper surface 102, in this embodiment at least 26 keypads 110. The lower surface 104 of the keypad 100 is preferably substantially planar, and the upper surface 102 of the keypad 100 can be planar or non-planar.
舉例而言，於一實施例，按鍵板100之上表面102實質為平面係指以肉眼或手指觸感無法明確辨識出相鄰按鍵區110之間有明顯邊界，亦即相鄰按鍵區110表面實質為連續的同一平面。當按鍵板100之上表面102為平面時，可藉由印刷、雷射刻印等技術於上表面102上以按鍵圖案區分出例如至少26個按鍵區110，以供使用者輸入操作指令，其中至少26個按鍵區110可對應於文字輸入按鍵(例如如英文字母、注音符號、***數字、標點符號等)、操作按鍵(如ENTER、SHIFT、CRTL、ALT等)、及熱鍵等按鍵圖案，供使用者識別相應的按鍵輸入內容。於另一實施例，按鍵板100之上表面102實質為非平面係指以肉眼或手指觸感可辨識出相鄰按鍵區110之間有明顯 邊界，亦即相鄰按鍵區110之間具有過渡區且過渡區與按鍵區110實質不共平面。具體而言，如圖1所示，按鍵板100之上表面102可形成有複數溝槽106(即過渡區)以界定出至少26個按鍵區110。亦即，複數溝槽106係以縱橫交錯之棋盤方式設置且自上表面102朝下表面104凹陷，以使至少26個按鍵區110為上表面102相對突出的區域。藉由溝槽106界定出按鍵區110，可讓使用者具有較佳的辨識觸感，以鍵入方式進行輸入動作時能更準確輸入按鍵指令，其中至少26個按鍵區110之表面上較佳具有印刷、刻印之按鍵圖案以對應於文字輸入按鍵、操作按鍵、及熱鍵等按鍵圖案，提示使用者輸入的對應按鍵指令。再者，按鍵板100於各按鍵區110亦可具有透光部分，以利於發光鍵盤的應用。亦即，各按鍵區110之按鍵圖案部分可由透光材質所構成而形成透光部分，以使光線可自按鍵板100之透光部分透射而出形成發光電腦鍵盤(如後詳述)。For example, in an embodiment, the upper surface 102 of the keypad 100 is substantially planar, and the naked eye or the finger touch does not clearly recognize that there is a clear boundary between the adjacent button regions 110, that is, the surface of the adjacent button region 110. The essence is the same plane that is continuous. When the upper surface 102 of the key sheet 100 is flat, at least 26 button areas 110 can be distinguished by a button pattern on the upper surface 102 by printing, laser marking, etc., for the user to input an operation instruction, at least The 26 button areas 110 can correspond to text input buttons (such as English letters, phonetic symbols, Arabic numerals, punctuation marks, etc.), operation buttons (such as ENTER, SHIFT, CRTL, ALT, etc.), and hot keys, etc. The user identifies the corresponding key input. In another embodiment, the upper surface 102 of the keypad 100 is substantially non-planar, and the naked eye or the finger touch can be recognized. The boundary, that is, the transition zone between adjacent button zones 110, and the transition zone and the button zone 110 are substantially non-coplanar. Specifically, as shown in FIG. 1, the upper surface 102 of the keypad 100 may be formed with a plurality of grooves 106 (ie, transition regions) to define at least 26 button regions 110. That is, the plurality of grooves 106 are disposed in a criss-crossing checkerboard pattern and are recessed from the upper surface 102 toward the lower surface 104 such that at least 26 of the button regions 110 are regions in which the upper surface 102 is relatively protruded. By defining the button area 110 by the groove 106, the user can have a better recognizable touch, and the button command can be input more accurately when the input action is performed by inputting, wherein at least 26 of the button areas 110 preferably have a surface. The printed and engraved button pattern prompts the user to input a corresponding button command corresponding to a key pattern such as a text input button, an operation button, and a hot key. Moreover, the keypad 100 can also have a light transmitting portion in each of the button regions 110 to facilitate the application of the illuminated keyboard. That is, the button pattern portion of each of the button areas 110 may be formed of a light-transmitting material to form a light-transmitting portion, so that light can be transmitted from the light-transmitting portion of the key sheet 100 to form a light-emitting computer keyboard (as will be described in detail later).
如圖1所示，開關層200係相對於按鍵板100設置。具體而言，開關層200係設置於按鍵板100之下表面104下方，並具有至少一開關區210對應於按鍵板100之至少一按鍵區110。舉例而言，開關層200具有至少26個開關區210分別對應按鍵板100的至少26個按鍵區110，其中依據施加於按鍵板100之第一操控力，電腦鍵盤10致動開關層200以執行相對應按鍵區110之按鍵輸入功能。每個開關區210包含網格式線路220，其中網格式線路220係由沿第一方向A排列設置之上層線路222及沿第二方向B排列設置之下層線路224構成，其中第一方向A及第二方向B係相互不平行且較佳為垂直。如圖1及圖2A所示，以一個開關區210之網格式線路220為例，各上層線路222可包含複數條上線路222a沿第一方向A相互間隔第一預定距離d1排列設置，且各上線路222a平行延伸於第二方向B，而各下層線路224可包含複數條下線路224a沿第二方向B相互間隔第二預定距離d2排列設置，且各下線路224a平 行延伸於第一方向A。複數上線路222a與複數下線路224a係以非接觸式地相互交錯而形成矩形網格式線路220，其中於複數上線路222a與複數下線路224a相互重疊之位置係形成複數對開關接點230。亦即，複數上線路222a與複數下線路224a相對於按鍵板100之厚度方向(即上表面102與下表面104間之垂直距離方向)係設置於不同的平行平面，而構成複數對開關接點230之複數上線路222a與複數下線路224a可因應使用者動作而選擇性接觸，以致動相應的按鍵開關，進而達到按鍵輸入的效果。As shown in FIG. 1, the switch layer 200 is disposed relative to the keypad 100. Specifically, the switch layer 200 is disposed under the lower surface 104 of the keypad 100 and has at least one switch region 210 corresponding to at least one button region 110 of the keypad 100. For example, the switch layer 200 has at least 26 switch areas 210 corresponding to at least 26 button areas 110 of the keypad 100, wherein the computer keyboard 10 actuates the switch layer 200 to perform according to the first manipulation force applied to the keypad 100. Corresponding to the key input function of the button area 110. Each switch area 210 includes a network format line 220, wherein the network format line 220 is composed of an upper layer line 222 arranged in a first direction A and a lower layer line 224 arranged along a second direction B, wherein the first direction A and the The two directions B are not parallel to each other and are preferably vertical. As shown in FIG. 1 and FIG. 2A , the upper layer line 222 may include a plurality of upper lines 222a arranged along the first direction A by a first predetermined distance d1, and each of the upper lines 222 is arranged. The upper line 222a extends in parallel with the second direction B, and each of the lower layer lines 224 may include a plurality of lower lines 224a arranged along the second direction B at a second predetermined distance d2, and each lower line 224a is flat. The row extends in the first direction A. The plurality of upper lines 222a and the plurality of lower lines 224a are non-contactly interleaved to form a rectangular net pattern line 220, wherein a plurality of pairs of switch contacts 230 are formed at positions where the plurality of upper lines 222a and the plurality of lower lines 224a overlap each other. That is, the plurality of upper lines 222a and the plurality of lower lines 224a are disposed on different parallel planes with respect to the thickness direction of the key sheet 100 (ie, the vertical distance between the upper surface 102 and the lower surface 104), and constitute a plurality of pairs of switch contacts.
