當從圖13所例示的狀態，操作者解除對可動構件12的按下時，可動構件12藉由施力構件14所施加的朝向上方的施加力而朝向上方移動，恢復為圖11所例示的狀態。When the operator releases the pressure on the movable member 12 from the state illustrated in FIG. 13 , the movable member 12 moves upward due to the upward urging force exerted by the urging member 14 and returns to the state illustrated in FIG. 11 condition.
圖14是表示本申請案揭示的鍵開關1的外觀的一例的概略立體圖。圖14是以來自斜下方的視點來表示鍵開關1，對應於前述的圖11所例示的狀態。圖14表示了鍵開關1未受到按下操作的狀態。如例示圖11所說明般，在鍵開關1未受到按下操作的狀態下，形成於可動構件12下表面的遮擋板124位於發光部103及受光部104的上方。因此，發光部103及受光部104之間的光路未被遮擋，從發光部103發出的光被受光部104檢測到。FIG. 14 is a schematic perspective view showing an example of the appearance of the key switch 1 disclosed in this application. FIG. 14 shows the key switch 1 from an obliquely downward perspective, and corresponds to the state illustrated in the aforementioned FIG. 11 . FIG. 14 shows a state in which the key switch 1 is not pressed. As illustrated in FIG. 11 , when the key switch 1 is not pressed, the shielding plate 124 formed on the lower surface of the movable member 12 is located above the light emitting part 103 and the light receiving part 104 . Therefore, the optical path between the light emitting part 103 and the light receiving part 104 is not blocked, and the light emitted from the light emitting part 103 is detected by the light receiving part 104 .
圖15是表示本申請案揭示的鍵開關1的外觀的一例的概略立體圖。圖15表示了從圖14所例示的狀態，可動構件12受到按下操作而移動至移動範圍的下限為止的狀態，對應於圖13所例示的狀態。藉由可動構件12移動至移動範圍的下限為止，形成於可動構件12下表面的遮擋板124進入發光部103及受光部104之間。因此，從發光部103發出的光被遮擋板124遮擋，而到達不了受光部104。FIG. 15 is a schematic perspective view showing an example of the appearance of the key switch 1 disclosed in this application. FIG. 15 shows a state in which the movable member 12 receives a pressing operation from the state illustrated in FIG. 14 until it moves to the lower limit of the movement range, and corresponds to the state illustrated in FIG. 13 . When the movable member 12 moves to the lower limit of the movement range, the shielding plate 124 formed on the lower surface of the movable member 12 enters between the light emitting part 103 and the light receiving part 104 . Therefore, the light emitted from the light emitting part 103 is blocked by the shielding plate 124 and does not reach the light receiving part 104 .
當從圖15所例示的狀態，操作者解除對可動構件12的按下時，可動構件12藉由施力構件14所施加的朝向上方的施加力而朝向上方移動，遮擋板124對光的遮擋被解除，恢復為圖14所例示的狀態。When the operator releases the pressure on the movable member 12 from the state illustrated in FIG. 15 , the movable member 12 moves upward by the upward urging force exerted by the urging member 14 , and the shielding plate 124 blocks the light. is released and returns to the state illustrated in Figure 14.
作為鍵盤KB的操作，使用者觸碰鍵開關1的可動構件12，進行按下可動構件12的按下操作，藉此，形成於可動構件12的遮擋板124遮擋從發光部103發出的光。藉由遮擋板124遮擋從發光部103朝向受光部104的光路，從而電路的接觸/分離狀態切換，從檢測到接觸/分離狀態的切換的鍵盤KB向所連接的個人電腦等的電子機器輸出每個鍵開關1的導通訊號。而且，藉由操作者解除可動構件12的按下，從發光部103發出的光的遮擋被解除，受光部104檢測到從發光部103發出的光。藉由解除從發光部103朝向受光部104的光路的遮擋，電路的接觸/分離狀態亦恢復為原本的狀態。As an operation of the keyboard KB, the user touches the movable member 12 of the key switch 1 and performs a pressing operation of pressing the movable member 12. This causes the shielding plate 124 formed on the movable member 12 to block the light emitted from the light emitting part 103. By blocking the light path from the light-emitting part 103 to the light-receiving part 104 with the blocking plate 124, the contact/separation state of the circuit is switched, and the keyboard KB that detects the switching of the contact/separation state outputs each signal to the connected electronic device such as a personal computer. The conduction signal of key switch 1.
