しかしながら、このような操作パネルは、エンボス加工された領域が小型化された場合にあっては、支点と作用点の距離が短くなることからエンボス加工部を下方へ押し込む力が大きくなり、さらには弾性部材を介してスイッチを作動させなくてはいけない為、操作性が悪くなってしまうといった問題点を有している。
そこで、本発明は、前述の問題点に着目し、小型化した操作領域であっても操作性に優れる操作パネルを提供することを目的とする。 However, when the embossed area is reduced in size, such an operation panel has a large force to push the embossed portion downward because the distance between the fulcrum and the working point is shortened. Since the switch must be operated through the elastic member, there is a problem that the operability is deteriorated.
Accordingly, the present invention focuses on the above-described problems, and an object thereof is to provide an operation panel that is excellent in operability even in a downsized operation region.

本発明は、表示部材４０と、前記表示部材４０を保持する弾性部材５０と、前記弾性部材５０を支持する支持体６０と、前記弾性部材５０により押圧されるスイッチ３０と、前記スイッチ３０を収容するケース体１０と、を備えた操作パネルであって、前記支持体６０は、前記ケース体１０に形成された開口１１に挿通される周壁部６２を有すると共に、前記弾性部材５０は、前記表示部材４０が嵌入される溝部５１ａを有する保持部５１と、前記ケース体１０と前記支持体６０とに挟持される固定部５２と、前記保持部５１と前記固定部５２とを連結する薄肉部５３と、が一体形成されているものである。 The present invention includes a display member 40, an elastic member 50 that holds the display member 40, a support body 60 that supports the elastic member 50, a switch 30 that is pressed by the elastic member 50, and the switch 30. The support body 60 has a peripheral wall portion 62 inserted through the opening 11 formed in the case body 10, and the elastic member 50 includes the display panel 10. a holding unit 5 1 having a groove 51a which member 40 is fitted, a fixing portion 52 which is sandwiched between the case body 10 and the support member 60, the thin portion connecting the fixing portion 52 and the holding portion 51 53 are integrally formed.

また、本発明は、前記表示部材４０を透過照明する発光素子８０を備えたものである。   In addition, the present invention includes a light emitting element 80 that transmits and illuminates the display member 40.

弾性部材によって表示部材を保持する構造とすることによって、操作性に優れた操作パネルとなる。   By adopting a structure in which the display member is held by the elastic member, an operation panel having excellent operability is obtained.
