Description of the Invention (I) The present invention relates to a keyboard unit as an input unit of an information processor, and a keyboard unit used in conjunction with this keyboard unit. button. More specifically, the present invention relates to a keyboard unit and a key switch suitable for a thin and portable personal computer. The exploded perspective view of FIG. 1 briefly illustrates a conventional key switch. 2A and 2B are vertical side views of the key switch in FIG. 1. The key switch is not pressed in Fig. 2A, and an operator in Fig. 2B presses the key switch. In the figure, the key switch 1 is located on a base plate 2 made of metal, plastic or other similar materials on one side. The key switch 1 has a thin film sheet 3 with electrical contacts 3a, and a pressing rubber 4 composed of an elastic insulator located above the thin film sheet 3. The click rubber 4 has an elastic round top 5 that covers the electrical contact 3 a of the thin film sheet 3 and a sheet-shaped part 6 located above the thin film sheet 3. At the same time, the key switch 1 has a keycap 7 in contact with the top of the dome 5 and a keycap 8. The keycap 7 has a hood sheet 7a, a support shaft 7b, and a cap flange portion 7c. The keycap cover 8 has a bearing portion 8a, which can support the support shaft 7b of the keycap 7, so that the keycap 7 can be rotated up and down on the bearing portion 8a. The keycap cover 8 also has an edge portion 8b. When pressed, it comes into contact with the edge portion 7c of the keycap 7. The function of the edge portion 8b of the keycap cover 8 is to serve as a stopper to prevent the keycap from slipping out. As described above, in the structure of the key switch 1 of FIG. 2B, when the keycap 7 is pressed by the operator, The support shaft 7b is pivoted downward, and the round top 5 4 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) | 1 _--- f ------ Cj pack-- -I ---- Order --------- Line (Please read the note on the back?

As a result of the deformation of the dome 5, the protrusion 5 a on the inner surface of the dome 5 is tightly pressed to the electrical contact 3 a in the thin film sheet 3. Sometimes, in the key switch 1, in order to prevent the operator's finger from hitting the keycap cover 8 when the keycap 7 is depressed, thereby reducing the performance of the operation, it is necessary to be in the free state (meaning, the key When the cap 7 is not depressed), the length Hi from the top surface of the keycap 8 to the highest apex of the keycap 7 is longer than the distance hs between the protrusion 5a and the electrical contact 3a that can be pressed. At the same time, the distance H2 from the bottom surface of the bottom plate 2 to the keycap 8 must be longer than the length He from the bottom surface of the bottom plate 2 to the top of the dome 5. However, in the key switch 1, suppose we lengthen the length Hs of the depression, and the top surface of the milk at the edge of the keycap 8 as the flap will be increased (that is, the length H2 will be higher). Therefore, the length Hi is increased, and the length Η〇 (= 底板 1 + H2) from the bottom surface of the bottom plate 2 to the top of the keycap 7 is longer, causing a problem that the thickness of the keyboard unit increases. At the same time, conversely, to make the keyboard thinner, it is necessary to sacrifice the depression length Hs. In other words, the touch length of the longer key switch and the reduced keyboard thickness cannot compromise each other. Therefore, an object of the present invention is to provide a key switch with a long touch length and a small thickness, and also provide a keyboard unit for use in combination. According to a design of the present invention, we propose a keyboard unit comprising: a base plate; an electrical contact on the base plate; an elastic round top formed on the base plate to cover the electrical contact; a bearing portion, It is located on the bottom plate; and a keycap, which has a bearing connected to the bearing portion, and a connecting portion connected to the round top. When the keycap is pressed down, the round top will be deformed elastically and pressed tightly to the electrical contact.

When the invention is described (5), the deformation of the round top disappears, which separates the inner surface of the round top from the electrical contact. Push the keycap up at the top. According to another design of the present invention, we propose a keyboard unit comprising: a base plate; and a plurality of key switches arranged in a row from an operator end near the operator to a remote end far from the operator end. Each of these key switches has an electrical switch located on the bottom plate; an elastic round top formed on the bottom plate to cover electrical contacts; a load-bearing portion on the bottom plate; and a keycap It has a bearing connected to the load bearing part and a connecting part connected to the round top. When the keycap is depressed, the dome will be elastically deformed and pressed tightly to electrical contact, and when the keycap is not depressed, the deformation of the dome disappears, separating the inner surface of the dome from the electrical contact. The round top pushes the keycap up. These key switches include an operator-side drop-type key switch and a remote-side drop-type key switch. Among the operator-side drop-type key switches, the load-bearing portion is located on the operator side relative to the keycap, and the remote In the distance-down type key switch, the load-bearing portion is located at a distance from the keycap. According to another design of the present invention, we propose a keyboard unit comprising: a bottom plate; an electrical contact on the bottom plate; an elastic round top formed on the bottom plate to cover the electrical contact; a starter having A support portion supported on the bottom plate so that the starter can be shaken on the support portion, and a first engaging portion opposite the supporting portion; and a keycap having an engaging portion with the first engaging portion of the starter The second connecting portion is connected, so that the keycap can be shaken on the second connecting portion of the starter. When the keycap is not pressed down, the round top will push the keycap up, so that the inner surface of the round top and (please read the precautions on the back before filling in this page) t Order --------- line Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) A7 B7 1995PIF1.D0C / 006 V. Description of the invention (4) Electrical contact is separated. When the free end relative to the second engaging portion of the keycap is depressed, the dome will be elastically deformed, so that the inner surface of the dome is tightly pressed against the electrical contact. When the first connecting portion of the starter moves downward, the dome will also be elastically deformed, so that the inner surface of the dome is tightly pressed to electrical contact.

A7 B7 1995PIF1 ,iX)C/006 五、發明說明（^ ) 圖10是根據本發明第三實施例的鍵盤單元的側視簡圖 0 第三實施例的鍵盤單元中，從操作員端（即圖10中的 左端）起，按照預定的規則排列了五行按鍵開關。 在此使用的按鍵開關41至45,結構都與第一實施例相同。 但是，第三實施例中的按鍵開關41至45也可以是第二實施 例的結構。 如圖10所示，在第三實施例的鍵盤單元中，第一、第 二與第五行的按鍵開關41、42和45的支撐軸41a、42a和 45a分別位在按鍵開關41、42和45的遠距端。而第三與第 四行的按鍵開關43、44的支撐軸43a、44a則分別位在按鍵 開關43、44的操作員端。 因此，當操作員觸擊第一、第二與第五行的按鍵開關 41、42和45時，鍵帽的操作員端會下降。同時，當操作員 觸擊第三與第四行的按鍵開關43、44時，鍵帽的遠距端會 .下降。 附帶說明的是，鍵盤單元的操作員通常會將手放在一 定的位置，然後移動各手指去觸擊每一行的按鍵開關，當 操作員觸擊第一行按鍵開關時，通常會用姆指，觸擊其他 行按鍵開關則用其他的手指。更仔細地說，對第一行來說 ，按鍵開關41位在操作員端的鍵帽頂部總是會由姆指觸擊 。對第二行來說，指尖會移到鍵帽的操作員端來觸擊。對 第四和第五行來說，指尖則是移到鍵帽的遠距端來觸擊。 20 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） I l·»----------'c裝--------訂---------線 (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 A7 B7 1995P1F1.DOC/006 五、發明說明（/?) 因爲第一行的按鍵開關41是操作員端下降型，鍵帽的 操作員端會下降，所以按鍵開關的運動方式就類似於姆指 觸擊按鍵開關41操作員端上的鍵帽頂端的運動方式。此外 ，因爲第二行的按鍵開關42是操作員端下降型，所以按鍵 開關的運動方式就類似於指尖觸擊按鍵開關4 2操作員端上 的鍵帽頂端的運動方式。這時，第一行和第二行的按鍵開 關41、42的頂面會略爲傾斜，使鍵帽的操作員端比遠距端 略爲高些。因此，操作員可以更容易觸擊按鍵開關。 此外，因爲第三行和第四行的按鍵開關43、44是遠距 端下降型，所以按鍵開關43、44的運動方式就類似於指尖 維持在固定位置而觸擊鍵帽遠距端的運動方式。因此，操 作員可以用手指自然的運動方式來觸擊這些按鍵開關，不 會覺得手指有任何不對勁。此外，第三行和第四行的按鍵 開關43、44的頂面會略爲傾斜，使鍵帽的遠距端比操作員 端略爲高些。因此，操作員可以更容易觸擊按鍵開關。 此外，當觸擊第五行按鍵開關45的鍵帽時，指尖的運 動距離是最遠的。因此，在按鍵開關45中，很容易觸擊到 鍵帽操作員端的頂部。因此，按鍵開關45的鍵帽會在支撐 軸45a上轉動，使鍵帽操作員端下降，所以鍵帽的運動方 式會類似於指尖觸擊鍵帽操作員端頂部時的運動方式。結 果，操作員就可以用手指的自然運動方式來觸擊按鍵開關 45的鍵帽，不會感覺到手指有任何不對勁的地方。 因此，在第三實施例的鍵盤單元中，第一、第二與第 五行的按鍵開關41、42和45的鍵帽是在操作員這一端下降 21 本紙張尺度適用中國國家標準（CNS)A4規辂（210 X 297公釐） I-ί I I ^-------^ ^--------^--------- (請先閲讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 B7 1995P1F1.D0C/006 五、發明說明（θ ) ，而第三與第四行的按鍵開關43、44的鍵帽是在遠距端下 降。因此，各鍵帽的下降運動都與操作員手指的運動方式 協調一致。因此，這樣的鍵盤不但可以製作得很小、很薄 ，而且當操作員觸擊各鍵帽時，操作員也不會感覺到手指 有什麼不對勁。換句話說，操作員可以操作得很舒適、很 正確，不會有操作上的錯務。 雖然以上的說明中，按鍵開關排成五行，但本發明並 不限於這種作法。 舉例來說，如圖11所示，本發明的鍵盤單元也可以有 第六行的按鍵開關46，而且當按鍵開關46的鍵帽在支撐軸 46a上轉動時，鍵帽的遠距端會下降。 同時，如圖12所示，本發明的鍵盤單元也可以有第六 行和第七行的按鍵開關46、47，而且當按鍵開關46、47的 鍵帽各自在支撐軸46a、47a上轉動時，鍵帽的遠距端都會 下降。 此外，如圖13所示，本發明的鍵盤單元也可以有第六 行和第七行的按鍵開關46、48，而且當按鍵開關46的鍵帽 在支撐軸46a上轉動時，鍵帽的遠距端會下降，而當按鍵 開關48的鍵帽在支撐軸48a上轉動時，鍵帽的操作員端會 下降。 ’ 第四實施例 圖14A是根據本發明第四實施例的鍵盤單元的透視圖 ，而圖14B是圖14A從箭頭Si 4B方向觀察的側視簡圖。 - 22 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） (請先聞讀背面之注意事頊再填寫本頁) 、裝--------訂-------！線^^&quot;. 經濟部智慧財產局員工消費合作社印製 經濟部智慧財產局員工消費合作社印製 199^PIF1 .ΓΧΧ7006 … + _____B7__ 五、發明說明（&gt;°) 第四實施例的鍵盤單元中，也按照預定的規則排列了 五行（舉例來說）按鍵開關。第四實施例與上述第三實施 例的差異只在於鍵盤單元操作員端的第一行上，排列了一 個寬大的空間按鍵51。 在圖14A的第四實施例鍵盤單元中，空間按鍵5 1的遠 距端有一個承載部（圖14A和圖14B未畫出），.可以支撐空 間按鍵51的鍵帽支撐軸51a，使鍵帽可以在支撐軸51a上轉 動。因此，當操作員壓下空間按鍵51時，空間按鍵51會在 支撐軸51a上轉動，使鍵帽的操作員端下降。空間按鍵51 的結構與上述第一實施例和第二實施例一樣。而且，空間 按鍵51的鍵帽，如圖14B所示，會略爲傾斜，使鍵帽靠操作 員一端高於遠距端。 此外，空間按鍵51以外的其他按鍵開關可以照第三實 施例排列。同時，也可使各鍵帽垂直下降，而使鍵帽的頂 面保持水平。此外，空間按鍵51同一行的其他按鍵開關， 也就是第一行的其他按鍵開關，可以與空間按鍵5丨同樣的 結構，也可以是不一樣的結構。 一般說來，空間按鍵51被觸擊的頻率是很高的。因此 ，人們吊會考慮使空間按鍵51局於其他的按鍵，以便提高 可靠性。但是，這種作法會妨礙鍵盤縮減厚度。第四實施 例的鍵盤單元中，使空間按鍵51的操作員端高於空間按鍵 51的遠距端，並在操作員端下降。因此，即使空間按鍵5 i ,高於其他按鍵，操作員一樣可以用姆指輕易地觸及空間按 鍵51，因此可以操作得很舒適、很正確。 23 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公愛) ------- (請先閱讀背面之注意事項再填寫本頁) --------訂-----— I— .

Description of the invention (//) The top of the dome 15 has a cylindrical top pipe 15a, and the back of the top of the dome 15 has a protrusion 15b Can be pressed tightly on the electrical contact 1 3a. A cross-sectioned hat frame 17f protrudes from the back of the keycap 17's hood piece 17a. The cap holder 17f is fitted into the dome 15a of the dome 15 so that the keycap 17 is not lifted, and faces the dome 15 in a right direction. In addition, the cross-sectional shape of the cap holder 17f is not limited to a cross shape. At the same time, the structure of the jack pipe 15a is not limited to a cylindrical shape. The assembly process of the key switch 11 in FIG. 6 and FIG. 7 will be exemplified below. For example, the cover sheet may be made of a plastic material and integrally formed with the bearing portion 19 and the blocking piece 21. At the same time, the keycap 17 can also be made of plastic material and formed together with the bearing portion 18 with the support shaft 18a and the cap holder 17f. First, the film sheet 13 is adhered to the bottom plate 12, the pressing rubber 14 is adhered, and then the cover sheet 20 is adhered. Then / the support shaft 18a of the keycap 17 is inserted into the load-bearing space formed between the load-carrying cavity 19a and the blocking piece 21, and the cap holder 17f is also fitted into the top pipe 15a of the dome portion 15. The bearing distance L in FIG. 7 is slightly smaller than the outer diameter of the support shaft 18a. Therefore, the support shaft 18a is pressed into the bearing space. At this time, the peripheral surface of the support shaft 18a will touch the bearing portion 19 and the blocking piece 21 to extend the load length L, so that the support shaft 18a is inserted into the load space. Once the support shaft 18a is inserted into the bearing cavity 19a, the bearing portion 19 and the blocking piece are elastically deformed. After that, the support shaft 18 a will be held in the bearing cavity 19 a and can be rotated freely without sliding out of the bearing cavity 19 a.

Description of Invention (1) Distortion. The deformation of the dome 15 causes the protrusion 15b on the inner surface of the dome 15 to press the electrical contact 13a in the thin film sheet 13 as a result, so that the electrical contact 13a is electrically connected. At this time, the height (or thickness) h2 from the bottom surface of the bottom plate 12 to the top surface of the cover sheet 20 does not need to be longer than the height He from the bottom surface of the bottom plate 12 to the top of the dome 15 like the traditional key switch in FIG. 2A. Therefore, the thickness h2 of the bottom surface of the keyboard of the key switch (including components 12, 13, 16, and 20) can be made smaller than the thickness of the traditional key switch (H2 in FIG. 2A). At the same time, if the distance hi from the top surface of the cover sheet 20 to the top of the keycap 17 is greater than the touch distance Hs, it is impossible for the operator's finger to touch the cover sheet 20 and affect the operation effect. Therefore, if the distance hi is equal to the traditional distance (distance Hi in FIG. 2A), the distance h0 (= hl + h2, representing the height of the keycap) from the bottom surface of the bottom plate 12 to the top of the keycap 17 can be smaller than the traditional distance (figure HO in 2A). In addition, if the distance h0 is equal to the conventional distance H0, the striking distance Hs of the first embodiment may be larger than the conventional striking 'distance in Fig. 2A. Next, the keyboard unit of FIG. 3 will be explained, in which the key switches 11 having the structure of FIGS. 6 and 7 are arranged in six rows. The lower end in FIG. 3, that is, the first and second rows of key switches 11 near the operator end (ie, the operator end), and the bearing portion 19 is located at the end far from the operator (ie, the remote end). It is the upper end in Figure 3. Therefore, when the keycap 17 is depressed, the keycap 17 is rotated around the support shaft 18a at the remote end as the axis, so that the operator end of the keycap 17 is lowered. This type of keycap will be hereinafter referred to as the operator end drop type. In addition, the key switches 11 in the third to sixth rows from the operator's end, and the bearing parts are located at 15 of each keycap π.

Therefore, the key switch ^} can be made small in thickness and long in touch length. At the same time, we use the key switch Π of the first embodiment to make a keyboard unit, so the keyboard unit can also be made with a long touch length and a small thickness. In addition, as illustrated in Fig. 5, if we use the keyboard unit, two rows of the operator end use the operator-side down key switches, and the four rows of the remote end use the remote end-down key switches. The curve formed by the parts will become a concave arc. In this way, the ergonomic components that have long been sacrificed because of priority to lower the height can be used, making the keyboard unit low and easy to operate. The first embodiment described above includes the baffle 21 and the support shaft 18a that supports the keycap 17 through the load bearing portion 18, but other methods can be used. 16 The paper size applies the Chinese National Standard (CNS) A4 specification.

The switch 41 is an operator-side lowered type, and the operator end of the keycap will be lowered, so the movement of the key switch is similar to the movement of the top of the keycap on the operator end of the key switch 41 with a thumb. In addition, since the key switches 42 in the second row are of the operator-side down type, the movement of the key switches is similar to the movement of the tip of the keycap on the operator end of the key switch 42 with a fingertip. At this time, the top surfaces of the key switches 41 and 42 in the first and second rows are slightly inclined, so that the operator end of the keycap is slightly higher than the remote end. Therefore, it is easier for the operator to touch the key switch. In addition, since the key switches 43 and 44 in the third and fourth rows are remote-type drop-down types, the movement of the key switches 43 and 44 is similar to the movement of touching the remote end of the keycap when the fingertip is maintained in a fixed position. the way. Therefore, the operator can use the natural motion of the finger to touch these key switches without feeling anything wrong with the finger. In addition, the top surfaces of the key switches 43, 44 in the third and fourth rows are slightly inclined, so that the remote end of the keycap is slightly higher than the operator end. Therefore, it is easier for the operator to touch the key switch. In addition, when the keycaps of the fifth-row key switches 45 are touched, the movement distance of the fingertip is the furthest. Therefore, in the key switch 45, it is easy to hit the top of the keycap operator end. Therefore, the keycap of the key switch 45 is rotated on the support shaft 45a, so that the operator end of the keycap is lowered, so the movement of the keycap is similar to that when a fingertip hits the top of the operator end of the keycap. As a result, the operator can use the natural motion of the finger to touch the keycap of the key switch 45 without feeling anything wrong with the finger. Therefore, in the keyboard unit of the third embodiment, the keycaps of the key switches 41, 42, and 45 of the first, second, and fifth rows are lowered at the operator's end. 21 This paper standard applies to China National Standard (CNS) A4.

The reason why the bearing parts of the key switches 61 to 66 should be arranged in the above-mentioned manner is that the inclined side of each of the key switches 61 to 66 can be consistent with the direction in which the cursor is moved or the display content is flipped. By designing the key switches 61 to 66 in this way, the direction in which the operator wants to move the cursor or the screen will be the same as the direction in which the key switches 61 to 66 are touched to descend. Therefore, the operator can touch these key switches 61 to 66 with a natural action, and the operation is proper and correct. Although the keyboard unit of the sixth embodiment includes arrow keys and up and down page keys, the present invention can also be applied to a keyboard unit containing only arrow keys or only up and down page keys. Seventh Embodiment. Fig. 17 is a vertical sectional view of a key switch according to a seventh embodiment of the present invention. Structures in FIG. 17 that are the same as those in FIGS. 6 and 7 are marked with the same reference numerals. The difference between the seventh embodiment and the first embodiment is that each key switch has two load-bearing parts, and the support shaft of the keycap can be selectively installed in any one of the load-bearing parts and can be disassembled. As shown in Fig. II, in addition to the carrying portion 19, there is another carrying portion 70 on the cover sheet 20. At the same time, the bearing portion 70 has a bearing cavity 70a (only one bearing cavity 70a is shown in FIG. 17), and another blocking piece 71 (only T1 is shown in FIG. 17) The paper size applies to the Chinese National Standard (CNS) A4 specification &lt; 210 X 297 mm)

Meanwhile, each of the bearing portion 70 and the blocking piece 71 has the same shape as the bearing portion 19 and the blocking piece 20. Therefore, the support shaft 18a of the keycap 17 (only one support shaft 18a is shown in FIG. 17) can be installed in the bearing portion 19 or the bearing portion 70, and can be removed. Therefore, for a key switch, as long as the bearing portion 19 connected to the support shaft 18a_ is changed to the bearing portion 70, or the bearing portion 70 is changed to the bearing portion 19, the lowering position when the keycap 17 is touched can be changed. . That is, for example, in a key switch, when the support shaft is inserted into the bearing portion of the remote end, the operator end of the keycap is lowered, and the support shaft can also be installed in the operator portion. The far end of the keycap is lowered. At this time, as long as the keycap 17 is very symmetrical on both sides of the support shaft 18a, the operator will not feel anything wrong, because even if the rotation of the keycap 17 differs by 180 degrees, the structure of the keycap 17 remains unchanged. As explained above, in the key switch of the seventh embodiment, the bearing portions 19 and 70, and the blocking pieces 21 and 71 are respectively located on opposite sides of the dome 15 of the pressing rubber M, and these components and keys The support shaft 18 a of the cap 丨 7 is detachable. Therefore, after removing the key cap 17 from the bearing portion, the key cap 17 can be rotated 180 degrees and then installed in the opposite bearing portion. Therefore, the direction in which the keycap 17 is rotated and lowered can be changed. In this way, the key switch is easy for all operators to avoid inappropriate input operations and input errors. 28 This paper size applies to China National Standard (CNS) A4 (21〇χ 297 mm) (Please read the precautions on the back before filling this page) — 丨 丨 丨 ί — Order --------波 ^^ ..

With this design, the joint portion between the support shaft 86b and the bearing portion 87b will serve as the rotation axis of the keycap 87, so that the keycap 87 can rotate on the rotation axis, and its rotation range is affected by the non-slip release in FIG. 19B Sub 86d and 87b restrictions. In addition, the engagement between the starter 86 and the keycap 87 is based on the elastic deformation of the starter 86 and the keycap 87. Therefore, the bearing portion 87a of the keycap 87 has a slot so that the support shaft 86b of the starter 86 can be tightly pressed into the bearing portion 87a. Therefore, the structure of the starter 86 and the keycap 87 allows the starter 86 to rotate on one axis on one end, and the keycap 87 rotates on one axis on the other end. Therefore, as a result of the engagement between the fixed portion 82a and the blocking piece 86e, and the engagement between the non-slip release catch 86d and the non-slip release catch 87b, even when the elastic force is restored by pushing the rubber 84 and the keycap 87 is pushed upward, the start The device 86 and the keycap 87 will not slip off. In addition, as a result of the positioning of the fixed portion 82a, the blocking piece 86e, the anti-slip release pawl 86d, and the anti-slip release pawl 87b, the rotation range (rotation angle) of the starter 86 is approximately the rotation range (rotation angle) of the keycap 87. 1/6 to 1/3. 32 (Please read the precautions on the back before filling this page) Chang -------- Order --------- Printed by the Consumers' Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs This paper is applicable to China Standard (CNS) A4 specification (210 X 297 mm) A7 1995P1F1 .D (X7006 B7 V. Description of the invention (knowledge) The example of pressing the keycap 87 below will explain the operation principle of the key switch 81 with the above structure. As shown in FIG. 19B, when the center of the free end of the keycap 87 is pressed in the direction of holding the arrow WA, the keycap 卞 7 of the key switch 81 will be on the support shaft 86b of the starter 86 like a conventional keycap. Turn clockwise to make the rubber round top 85 pressed and deformed.

When the starter 86 rotates and descends, and contacts the bottom plate 82, the keycap 87 will rotate in a clockwise direction on the support shaft 86b of the starter 86 As a result of the rotation and lowering of the keycap 87, the pressing rubber 84 is pressed tightly, and then the electrical contact 83a of the film sheet 83 is electrically connected as in the above case. When the operator's finger is removed from the keycap 87 When pressing the elastic restoring force of the round top 85 of the rubber 84, the keycap 87 will be lifted. At the same time, because the keycap 87 is lifted, the starter 86 connected to the keycap 87 will also be close to the fixed protrusion 86c. The electrical properties of the diaphragm 83 are caused by the upward deformation of the rotating shaft near the connection portion of the fixed portion 82a of the bottom plate 82 (please read the idea on the back before filling this page).

tg D 1 QjN 誠如以上的說明，第八實施例的按鍵開關81中，起動 器86位在底板82與鍵帽87之間，而且起動器86的轉動方向 也與鍵帽87的轉動方向相反。因此，這樣的按鍵開關中， 當壓下鍵帽87時，鍵帽87會在起動器86之支撐軸86b上向 下轉動，而起動器則在靠近固定的突出物86c和底板82之 固定部82a啣接位置附近的轉動軸上向下轉動。因此，舉 例來說，即使壓下鍵帽87固定端附近，與壓下鍵帽87轉動 端的情形相較之下，也不致使操作員手指對觸擊鍵帽87的 感受大大減弱。 因此，在按鍵開關81中，即使操作員用觸擊鍵帽87轉 動端的相同力量來觸擊鍵帽87的固定端，傳到操作員手指 的衝擊力量也會被抑制。同時，在按鍵開關81中，即使觸 擊鍵帽87的固定端，因爲起動器86會向下轉動，操作員的 手指仍能感受到某一程度的觸撃。因此，按鍵開關81會更 容易操作。 此外，第八實施例的按鍵開關的結構使得起動器86的 轉動角度約爲鍵帽87轉動角度的1/6至1/3。有了這樣的設 計，當觸擊按鍵時，鍵帽87轉動角度與起動器86轉動角度 .之間的平衡會更恰當，因而得以抑制壓下鍵帽87固定端時 ，傳到操作員手指上的衝擊力，確保操作員的觸擊更爲舒 適。 34 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐）

(操作員手指直接接觸的部位）相對於起動器 106的方向與上述第八或第九實施例的鍵帽相反。也就是 說，在第十實施例的鍵帽107中，支撐軸啣接部l〇7a位在 鍵盤單元相對於操作員端（帽緣l〇7d的一端）的遠距端（ 帽緣107e的一端）上，而且如圖25A所示，帽緣107d會高 於帽緣丨07e。另一方面，在上述第八或第九實施例的鍵帽 中，操作員端卻低於另一端。 _ 圖25A至25C中，起動器106支撐軸106b的頂面上有兩 個傾斜的部位111、112。同樣的，起動器106支撐軸106b 的底面上也有兩個傾斜的部位113、114。當起動器106的 支撐軸106b安入固定部l〇2a的方形開孔102b時，如圖25A 和25B所示，起動器1〇6只能轉動到傾斜部位ill、in其中 之一接觸到方形開孔102b的上表面，或傾斜部位113、114

如圖26A所示，如果以箭頭Wa的方向壓下鍵帽107自由 端（位在操作員端）中心時，這個按鍵開關1〇1的鍵帽1〇7 會與傳統的鍵帽一樣，在起動器106的轉動軸（即軸i〇6c )上以逆時鐘的方向往下轉動，使得按壓橡膠1〇4的圓頂 部105被緊壓而變形。圓頂部1 〇5緊壓變形造成圓頂部1 〇5 的突出物105e緊壓薄膜片103裏的電性接觸l〇3a。結果， 在按鍵開關101中，電性接觸l〇3a就得以電性連接。如果 操作員的手指從鍵帽107上移開時，圓頂部1〇5的彈性恢復 力會將鍵帽107推上來，回復到圖26A的狀態。 另一方面，如圖26B所示，如果以箭頭Wb的方向壓下 鍵帽107的遠距端l〇7e，也就是鍵帽1〇7固定端的中心時， 按鍵開關101的起動器106首先會在支撐軸1〇4的轉動軸115 上以順時鐘的方向往下轉動。起動器1〇6轉動並下降直到 支撐軸106b的傾斜部位111接觸到方形開孔i〇2b的上表面 ，而支撐軸106b的傾斜部位113也接觸到方形開孔i〇2b的 下表面（圖25C)。這時，如圖26B所示，起動器1〇6會緊 壓彈簧部104b。 接著，如圖26C所示，鍵帽107會在起動器丨〇6的支撐 軸106c上以順時鐘的方向轉動並下降。鍵帽1〇7的轉動並 38 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公楚） —

並按壓橡膠104彈簧部104b的彈力的帶動下，起動器106會 在支撐軸104b的轉動軸115上往上轉動。這樣一來，按鍵 開關101就會回復到圖26A的狀態。 圓頂部105的彈性恢復力會隨著時間逐漸減弱。按壓 橡膠104彈簧部104b可以補償圓頂部105減弱的彈性恢復力 。因此，有了這種彈簧部104b後，按鍵開關和使用這種按 鍵開關的鍵盤單元就能更加持久。 在上述第十實施例的按鍵開關101中，即使壓下鍵帽 107固定端附近，也不致使操作員手指對觸擊鍵帽107的感 受大大減弱。因此，按鍵開關101會抑制傳到操作員手指 的衝擊力量，使操作員更容易操作。 . 同時，在第十實施例中，支撐軸106b不但作爲起動器 106的轉動軸，也會限制起動器106的轉動，所以起動器 106所需要的組件就可以減少，結構也更爲輕巧。 此外，支撐軸l〇6b的結構並不限於上面所描述的支撐 軸。舉例來說，支撐軸104的傾斜部位並不都是直線形， 只要有限制轉動的功能，也可以是其他的形狀。 圖27是第十實施例變化後的剖面圖。在這種變化設計 的按鍵開關中，鍵帽的方向與圖2 5 A中的按鍵開關1 〇 1相反 。在這個設計中，只要將鍵帽107的支撐軸啣接部l〇7a放 39 本^張尺玉適用中國國家標準（CNS)A4 ¥格（210 X

圖28是第十實施例另一種變化的剖面圖。這種變化與 圖25A的差異只在於圖25A的彈簧部104b由片狀彈簧12◦代 替，好將起動器106推上來。 圖29是第十實施例再一種變化的剖面圖。在這種設計 中，支撐軸106b固定在底板102的固定部102a上，使起動 器106固定後，會像圖29中實線所表示的一樣呈現傾斜的 狀態。當壓下鍵帽107使起動器106彎下來時，起動器106 會彎成圖29中虛線所代表的狀態，並由起動器106的彈性 恢復力往上推。當沒有壓下鍵帽107時，起動器106就會回 復到圖29中實線的傾斜狀態。 此外，也可利用上述實施例的按鍵開關來組成鍵盤單 元。在這種情形下，使用這種可以抑制傳送到操作員手指 的衝擊力、使操作員更容易操作的按鍵開關，就可以組成 輸入操作可靠的鍵盤單元。 同時，在上述的按鍵開關中，不但是鍵帽107，連起 動器106也可以轉動，因此，與只有鍵帽1 〇7可以轉動的情 形相比之下，從壓下鍵帽107到連接電性接觸之間鍵帽107 的轉動角度就可以縮小。因此，如果使用這個實施例的按 鍵開關來作成鍵盤單元，就可以縮小整個按鍵開髖的觸擊 40 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） (請先間讀背面之注咅？事項再填寫本頁) 裝i丨！-丨丨訂- -------^^^1 .

bottom plate 82 and the key cap 87, and the direction of rotation of the starter 86 is opposite to the direction of rotation of the key cap 87. . Therefore, in such a key switch, when the key cap 87 is depressed, the key cap 87 rotates downward on the support shaft 86b of the starter 86, and the starter is near the fixed protrusion 86c and the fixed portion of the bottom plate 82 82a rotates downward on the rotating shaft near the engaging position. Therefore, for example, even if the vicinity of the fixed end of the keycap 87 is depressed, as compared with the case where the rotating end of the keycap 87 is depressed, the feeling of hitting the keycap 87 by the fingers of the operator is not greatly reduced. Therefore, in the key switch 81, even if the operator touches the fixed end of the keycap 87 with the same force as the rotating end of the keycap 87, the impact force transmitted to the finger of the operator is suppressed. Meanwhile, in the key switch 81, even if the fixed end of the keycap 87 is touched, since the starter 86 rotates downward, the operator's finger can still feel a certain degree of thumping. Therefore, the key switch 81 is easier to operate. In addition, the structure of the key switch of the eighth embodiment enables the rotation angle of the starter 86 to be approximately 1/6 to 1/3 of the rotation angle of the keycap 87. With such a design, when the key is touched, the balance between the rotation angle of the key cap 87 and the rotation angle of the starter 86 will be more appropriate, so that the fixed end of the key cap 87 can be suppressed from being transmitted to the operator's finger when pressed. The impact force ensures that the operator's strike is more comfortable. 34 This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) San ----, Ding --------- Φ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1 (W5P 丨 FI.DOC / 006 __ B7 V.

The same structures in Figs. 21 and 22 as in Figs. 19A to 19D and Fig. 20 are marked with the same The difference between the key switch 91 of the ninth embodiment and the eighth embodiment described above lies in the structure of the bottom plate and the starter. As shown in FIG. 21, the bottom plate 92 has two fixing portions 92a and 92b. In this embodiment, The surfaces of the fixing portions 92a and 92b will be perpendicular to the surface of the fixing portion 82a in the eighth embodiment. At the same time, the openings 92c and 92d of the fixing portions 92a and 92b are located on the upwardly extending portions, respectively. There is a support shaft 96a in position, unlike the fixed projection 86c in the eighth embodiment described above. The rotation baffle 96b of the starter 96 is close to the support shaft 96a, unlike the baffle 86 in the eighth embodiment. In addition, the support shaft 96a is close to the end opposite the support shaft 86b, and the rotation baffle 96b is located at the support The opposite end of the shaft 86b. At the same time, the openings 93b and 93c in the film 93 and the openings 94a and 94b in the pressing rubber 94 correspond to the fixed portions 92a and 92b of the bottom plate 92. Staff of the Bureau of Intellectual Property, Ministry of Economic Affairs The consumer cooperative is printed on the key switch 91 of the ninth embodiment. As shown in FIG. 22, the support shaft 96a of the starter 96 will fit into the openings 92c and 92d of the fixed portions 92a and 92b of the bottom plate 92. The starter 96 and The engagement between the bottom plates 92 is based on the elastic deformation of the starter 96. The starter 96 can freely rotate as the rotation axis. The rotation stopper 96b of the starter 96 will contact the bottom plate 92, so the starter can be prevented% Slipping can also limit the rotation angle of the starter 96. 35 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1995PIFI.DOC / 006 A7 ___B7______ 5. Description of the invention (shirt) (please first闿 Read the notes on the back and fill in (This page) In addition, as shown in FIGS. 23A and 23B, it is also possible to use twin, 屮, rotating flaps 96c near the support shaft 96a (only one flap 96c is drawn in FIGS. 23A and 23B) in place of FIG. 22 Stopper% b. When the starter 96 rotates on the support shaft 96a, the rotation stopper 96c in FIGS. 23A and 23B will contact the fixed portions 92a and 92b on the bottom plate 92, so that the starter 96 does not slip and rotate at an angle It will also be restricted. As explained above, in the key switch 91 of the ninth embodiment, even if the fixed end portion of the keycap 97 is depressed, the feeling of the operator's finger against the keycap 97 is greatly reduced. Therefore, the key switch 91 suppresses the impact force transmitted to the operator's finger, making it easier for the operator to operate. Tenth Embodiment Λ 24 is an exploded perspective view of a key switch according to a tenth embodiment of the present invention, Fig. 25A is a vertical sectional view of the key switch of Fig. 24, and Figs. 25B and 25C are enlarged views of a support shaft in Fig. 25A. The same structures in FIGS. 24 and 25A to 25C as those in FIGS. 19A to 19D and FIG. 20 are marked with the same reference numerals. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs In Figure 24, the base plate 102 has a pair of fixed portions 102a facing each other. The position of the fixing portion 102a is the same as that of the fixing portions 92a and 92b in the ninth embodiment described above. At the same time, the fixed portions 102a also have square openings 102b in the upwardly extending portions. In addition, when the pressing rubber 104 is produced, two spring portions 104b are formed at the same time to push the starter 106 up. The starter 106 is generally U-shaped, and a control portion 106a is provided at the middle portion thereof so that the round top 105 of the pressing rubber 104 can be inserted. At the same time, the starter 106 has a support shaft 106b at each of the two positions. The paper size of the starter 36 is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297ϋΤ A7 B7 1995P1FLDCXV006) 5. Description of the invention 106 On the free end relative to the support shaft 1 06b, there is also the connecting shaft 1 06c. Support Between the shaft 106b and the connecting shaft 106c, there is a fat-slipping pawl 106d. The back (that is, the bottom surface) of the keycap 107 is provided with a supporting shaft engaging portion 107a and a non-slip releasing pawl 107b. The supporting shaft is engaged The position of the part 107a corresponds to the engaging shaft 106c of the starter 106. The non-slip release pawl 107b of the keycap 107 will be engaged with the non-slip release pawl 106d of the starter 106. In the tenth implementation In the keycap 107 of the example, the direction of the cap portion 107c (the portion directly contacted by the operator's finger) with respect to the starter 106 is opposite to that of the keycap of the eighth or ninth embodiment. That is, in the tenth In the keycap 107 of the embodiment, the support shaft engaging portion 107a is located on the remote end (the end of the cap edge 107e) of the keyboard unit relative to the operator end (the end of the cap edge 107d), and as shown in FIG. As shown in 25A, the cap edge 107d is higher than the cap edge 07e. On the other hand, in the keycap of the eighth or ninth embodiment described above, The operator end is lower than the other end. _ In Figs. 25A to 25C, there are two inclined parts 111, 112 on the top surface of the starter 106 supporting shaft 106b. Similarly, the bottom surface of the starter 106 supporting shaft 106b also has two 113, 114. When the support shaft 106b of the starter 106 is inserted into the square opening 102b of the fixed portion 102a, as shown in Figs. 25A and 25B, the starter 106 can only rotate to the inclined portion ill.

The following will refer to FIGS. 26A to 26C and FIG. 25C The operation when the keycap 10 is depressed is explained. The vertical sectional views of FIGS. 26A to 26C illustrate the operation of the key switch 101 of the tenth embodiment. As shown in FIG. 26A, if the center of the free end (located at the operator end) of the keycap 107 is pressed in the direction of the arrow Wa, the keycap 107 of the key switch 101 will be the same as the traditional keycap. The rotating shaft (i.e., the shaft 106) of the starter 106 is rotated downward in a counterclockwise direction, so that the dome 105 pressing the rubber 104 is tightly deformed. The dome 105 is pressed and deformed tightly to cause the protrusion 105e of the dome 105 to tightly press the electric contact 103a in the film sheet 103. As a result, in the key switch 101, the electrical contact 103a is electrically connected. If the operator's finger is removed from the keycap 107, the elastic restoring force of the dome 105 will push up the keycap 107 and return to the state of FIG. 26A. On the other hand, as shown in FIG. 26B, if the distal end 107e of the keycap 107 is depressed in the direction of the arrow Wb, that is, the center of the fixed end of the keycap 107, the starter 106 of the key switch 101 will first Rotate down on the rotation shaft 115 of the support shaft 104 in a clockwise direction. The starter 106 is rotated and lowered until the inclined portion 111 of the support shaft 106b contacts the upper surface of the square opening i02b, and the inclined portion 113 of the support shaft 106b also contacts the lower surface of the square opening i02b (Fig. 25C). At this time, as shown in Fig. 26B, the starter 106 presses the spring portion 104b. Next, as shown in FIG. 26C, the keycap 107 is rotated clockwise on the support shaft 106c of the starter 106 and lowered.

If the operator's finger is removed from the keycap 107, the elastic restoring force of the round top 105 will push the keycap 107 up. At the same time, push up on the keycap 107 and press the rubber 104 spring 104b Driven by the elastic force, the starter 106 will rotate upward on the rotation shaft 115 of the support shaft 104b. In this way, the key switch 101 will return to the state of FIG. 26A. The elastic restoring force of the dome 105 will gradually increase with time. Weakening. Pressing the rubber 104 spring portion 104b can compensate for the weakened elastic restoring force of the dome 105. Therefore, with this spring portion 104b, the key switch and the keyboard unit using the key switch can be more durable. In the push switch 101 of the embodiment Even if the vicinity of the fixed end of the keycap 107 is depressed, the feeling of the operator's finger touching the keycap 107 is not greatly reduced. Therefore, the key switch 101 suppresses the impact force transmitted to the operator's finger, making it easier for the operator to operate. At the same time, in the tenth embodiment, the support shaft 106b not only serves as the rotation shaft of the starter 106, but also restricts the rotation of the starter 106, so the components required for the starter 106 can be reduced and the structure is more lightweight. The structure of the support shaft 106b is not limited to the support shaft described above. For example, the inclined parts of the support shaft 104 are not all linear, and may have other shapes as long as they have a function of restricting rotation. 27 is a sectional view of the tenth embodiment after the change.

In this way, when the key switches are arranged on the keyboard unit, it is easy to arrange the form that is convenient for the operator to operate, for example, it is like a concave arc. Figure 28 is the first A cross-sectional view of another variation of the tenth embodiment. This change is different from FIG. 25A only in that the spring portion 104b of FIG. 25A is replaced by a leaf spring 12 so that the starter 106 is pushed up. Fig. 29 is a sectional view showing still another variation of the tenth embodiment. In this design, the support shaft 106b is fixed to the fixing portion 102a of the bottom plate 102, and after the starter 106 is fixed, it will appear inclined as shown by the solid line in FIG. When the starter 106 is bent down by depressing the keycap 107, the starter 106 is bent into a state represented by a broken line in FIG. 29, and is pushed up by the elastic restoring force of the starter 106. When the keycap 107 is not depressed, the starter 106 returns to the inclined state of the solid line in Fig. 29. In addition, a keyboard unit may be formed by using the key switches of the above embodiments. In this case, a keyboard unit with reliable input operation can be constituted by using the key switch which can suppress the impact force transmitted to the operator's finger and make it easier for the operator to operate. At the same time, in the above-mentioned key switches, not only the keycap 107 but also the starter 106 can be rotated. Therefore, compared with the case where only the keycap 107 can be rotated, from the depression of the keycap 107 to the connection The angle of rotation of the keycap 107 between sexual contacts can be reduced. Therefore, if the key switch of this embodiment is used to make a keyboard unit, the entire touch of the hips can be reduced.
