As shown in FIGS. 3 to 5, the LED 34 b is mounted on the substrate 34 so as to be visible from the bag receiving portion 33 a.

充電台7は、携帯電話機1を充電するための置き台であり、電源に接続されるコンセントプラグ部や携帯電話機1との接点部を備える。充電時にはLED34bが発光し、図9に示すように、携帯電話機1が充電台7に設置された状態で、導光材5を通じてLED34bの発光が視認される。   The charging stand 7 is a pedestal for charging the mobile phone 1 and includes an outlet plug portion connected to a power source and a contact portion with the mobile phone 1. During charging, the LED 34b emits light, and as shown in FIG. 9, the light emission of the LED 34b is visually recognized through the light guide member 5 in a state where the mobile phone 1 is installed on the charging stand 7.

次に、上記構成の導光材5と嵌合パッキン6を用いてキー装置4を中ケース33に装着する方法について図7を参照して説明する。
まず、嵌合パッキン6を中ケース33に装着する。中ケース33の嵌合受口部33cと嵌合パッキン6の嵌合部6c、及び、中ケース33の突起部33bと嵌合パッキン6の突起受口部6bが合致するよう中ケース33と嵌合パッキン6の位置調節を行い、各部が合致したら嵌合パッキン6を押圧する。
嵌合パッキン6が押圧されると、嵌合部6cが嵌合受口部33cに挿入され、嵌合受光部33cは塞がれる。また、突起部33bが突起受口部6bに挿入され、嵌合パッキン6は中ケース33に密着する。このため、嵌合パッキン6は中ケース33に固着し、嵌合受口部33cから中ケース33の内部に水等が浸入するのを防ぐことができる。
Next, a method for mounting the key device 4 to the middle case 33 using the light guide member 5 and the fitting packing 6 having the above configuration will be described with reference to FIG.
First, the fitting packing 6 is attached to the middle case 33. The middle case 33 is fitted with the middle case 33 so that the fitting receiving portion 33c of the middle case 33 and the fitting portion 6c of the fitting packing 6 and the projection 33b of the middle case 33 and the projection receiving portion 6b of the fitting packing 6 are matched. The position of the mating packing 6 is adjusted, and when the respective parts match, the mating packing 6 is pressed.
When the fitting packing 6 is pressed, the fitting portion 6c is inserted into the fitting receiving portion 33c, and the fitting light receiving portion 33c is closed. Further, the protrusion 33 b is inserted into the protrusion receiving portion 6 b, and the fitting packing 6 is in close contact with the middle case 33. For this reason, the fitting packing 6 adheres to the middle case 33, and water or the like can be prevented from entering the middle case 33 from the fitting receiving portion 33c.

続いて、キー装置4を中ケース33に装着する。キー装置4の袋状部4cと中ケース33の袋受口部33a、キー装置4の突起受口部4bと中ケース33の突起部33b、及び、操作ボタン41のボタン脚部41bと嵌合パッキン6の脚受口部6aが合致するようキー装置4と中ケース33の位置調節を行い、各部が合致したらキー装置4を押圧する。
キー装置4が押圧されると、袋状部4cが袋受口部33aに挿入され、キー装置4の一端が中ケース33に固定される。また、突起部33bが突起受口部4bに挿入され、キー装置4の他端が中ケース33に固定される。このため、キー装置4の両端が固定され、キー装置4が中ケース33に装着される。
Subsequently, the key device 4 is attached to the middle case 33. The bag-like portion 4c of the key device 4 and the bag receiving portion 33a of the middle case 33, the protrusion receiving portion 4b of the key device 4 and the protruding portion 33b of the middle case 33, and the button leg portion 41b of the operation button 41 are fitted. The positions of the key device 4 and the middle case 33 are adjusted so that the leg receiving portions 6a of the packing 6 are matched, and the key device 4 is pressed when the respective portions are matched.
When the key device 4 is pressed, the bag-like portion 4c is inserted into the bag receiving portion 33a, and one end of the key device 4 is fixed to the middle case 33. Further, the protrusion 33 b is inserted into the protrusion receiving portion 4 b, and the other end of the key device 4 is fixed to the middle case 33. For this reason, both ends of the key device 4 are fixed, and the key device 4 is attached to the middle case 33.

最後に、導光材5を導光材受口部4aに挿入し、キー装置4が中ケース33から外れることを防ぐ。導光材5が導光材受口部4aに挿入されると、導光材5は袋状部4cの袋内部の側面を押圧するため、袋状部4cと袋受口部33aが密着する。このため、キー装置4は、中ケース33に安定に固定される。   Finally, the light guide member 5 is inserted into the light guide member receiving portion 4 a to prevent the key device 4 from being detached from the middle case 33. When the light guide material 5 is inserted into the light guide material receiving portion 4a, the light guide material 5 presses the side surface inside the bag of the bag-like portion 4c, so that the bag-like portion 4c and the bag receiving portion 33a are in close contact with each other. . For this reason, the key device 4 is stably fixed to the middle case 33.

以上説明したように、キー装置4の両端及びほぼ中央部の3箇所が固定され、キー装置4は、中ケース33に安定に装着される。キー装置4を携帯電話機1に内包する際には、キー装置4は、図8に示すように、上ケース31から押圧され圧縮された状態で収容され、中ケース33をシールするため、携帯電話機1の内部に水等が浸入するのを防止できる。また、キー装置4の袋状部4cは、キー装置4を中ケース33に固定する機能と、導光材5が挿入され携帯電話機1の表面に光を案内する機能の2つを備えるため、部品点数が削減され、キー装置4が小型化される。   As described above, the key device 4 is fixed to the middle case 33 in a stable manner, with the three ends of the key device 4 being fixed at the center and the central portion. When the key device 4 is included in the mobile phone 1, the key device 4 is received from the upper case 31 in a compressed state and sealed in the middle case 33, as shown in FIG. It is possible to prevent water or the like from entering the interior of the 1. Further, the bag-like portion 4c of the key device 4 has two functions: a function of fixing the key device 4 to the middle case 33 and a function of guiding the light to the surface of the mobile phone 1 with the light guide member 5 inserted therein. The number of parts is reduced, and the key device 4 is reduced in size.

操作ボタン41の操作を検知する方法について図8を参照して説明する。
操作者がボタン頭部41aを押下すると、連動してボタン脚部41bが下降し、ボタン脚部41bの底面が、嵌合部6cの底面を押下する。続いて、嵌合部6cの底面が下降し、接点34aを押下する。すると、接点34aがオンし、オン信号が図示せぬCPUに供給され、CPUは操作ボタン41の操作を検知する。
A method for detecting the operation of the operation button 41 will be described with reference to FIG.
When the operator presses the button head portion 41a, the button leg portion 41b is lowered in conjunction with it, and the bottom surface of the button leg portion 41b presses the bottom surface of the fitting portion 6c. Subsequently, the bottom surface of the fitting portion 6c is lowered to press the contact 34a. Then, the contact 34a is turned on, and an on signal is supplied to a CPU (not shown), and the CPU detects the operation of the operation button 41.

なお、本発明は上記実施の形態に限定されず、種々の変形及び応用が可能である。   In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.
