Hereinafter, an embodiment of the portable device will be described.
As shown in FIG. 1, the portable device 1 possessed by the user as a vehicle key is capable of wireless communication with an in-vehicle device, and is a case for holding the board in addition to the board 3 on which the antenna 2 serving as a communication medium is mounted. 4. The battery 5 and the battery cover 6 are housed in the decorative case 7. The battery cover 6 is detachably attached to the board holding case 4 to form a battery ejecting portion.
基板３には、アンテナ２の他、車両の動作（ドアロックの施解錠等）が割り当てられたスイッチ８、通信制御等を実行するマイコン（図示略）、バッテリ５が接続されるターミナル（図示略）が実装されている。 In addition to the antenna 2, the board 3 has a switch 8 to which vehicle operations (door lock locking / unlocking, etc.) are assigned, a microcomputer (not shown) that executes communication control, and a terminal (not shown) to which a battery 5 is connected. ) Is implemented.
尚、加飾用のケース７は、上下一対のケース（アッパケースとロアケース）からなり、アッパケース（図示略）に組み付けられたボタンが押下されると、ボタン直下のスイッチ８がオンすることにより、該スイッチ８に割り当てられた動作を指示する無線信号がアンテナ２を通じて外部に送信される。 The decorative case 7 is composed of a pair of upper and lower cases (upper case and lower case), and when a button assembled to the upper case (not shown) is pressed, the switch 8 directly under the button is turned on. , A radio signal instructing the operation assigned to the switch 8 is transmitted to the outside through the antenna 2.
図２（ａ）、（ｂ）に示すように、基板保持用のケース４は、基板３の保持機能を実現する基板保持部１１を有して硬質樹脂により略台状に形成されるとともに、所要箇所にシリコーンゴムがインサート成形されている。 As shown in FIGS. 2A and 2B, the substrate holding case 4 has a substrate holding portion 11 that realizes a holding function of the substrate 3 and is formed in a substantially trapezoidal shape by a hard resin. Silicone rubber is insert-molded at the required points.
そして、弾性を有するシリコーンゴムによって、基板保持用のケース４の表側には、基板保持部１１で保持する基板３への衝撃を緩和する機能を実現する基板保護部１２が形成されるとともに、基板３に実装されるアンテナ２の保護機能を実現するシート状のアンテナ保護部１３が形成されている。同じく基板保持用のケース４の裏側には、バッテリ取り出し部の防水機能を実現するリング状の防水シール部１４が形成され、さらに、該ケース４の側部における加飾用のケース７との嵌合部には、加飾用のケース７内に収容された部品を衝撃から保護する機能を実現する突状の衝撃吸収部１５が形成されている。 Then, the elastic silicone rubber forms a substrate protection portion 12 on the front side of the substrate holding case 4 to realize a function of cushioning the impact on the substrate 3 held by the substrate holding portion 11, and also forms a substrate. A sheet-shaped antenna protection portion 13 that realizes the protection function of the antenna 2 mounted on the 3 is formed. Similarly, on the back side of the case 4 for holding the substrate, a ring-shaped waterproof seal portion 14 that realizes a waterproof function of the battery take-out portion is formed, and further, the side portion of the case 4 is fitted with the case 7 for decoration. A protruding shock absorbing portion 15 is formed in the joint portion to realize a function of protecting the parts housed in the decorative case 7 from impact.
基板保護部１２、アンテナ保護部１３、防水シール部１４、衝撃吸収部１５は、基板保持部１１による基板３の保持機能（基板保持用のケース４における元来の機能）とは異なるそれぞれの機能を実現する他機能部に相当する。 The board protection section 12, the antenna protection section 13, the waterproof seal section 14, and the shock absorbing section 15 have different functions from the board 3 holding function (the original function in the board holding case 4) by the board holding section 11. Corresponds to other functional parts that realize.
次に、携帯機１の作用について説明する。

Then, silicone rubber is insert-molded into the battery cover 26 to form a waterproof seal shape 28. In this case, the holding function of the board 22 is carried out by the case 24 for holding the board, the protective function of the antenna 21 is carried out by the sheet 23 for protecting the antenna, and the waterproof function of the battery ejecting portion is carried out by the cover 26 for the battery. Since the three functions are performed by three parts, the number of parts and the assembly man-hours increase.
これに対し、本例の携帯機１は、基板３の保持機能の他、アンテナ２の保護機能、バッテリ取り出し部の防水機能を基板保持用のケース４で実施するとともに、基板３への衝撃を緩和する機能及び加飾用のケース７内に収容された部品を衝撃から保護する機能についても基板保持用のケース４で実施するため、部品点数及び組付け工数を低減できる。 On the other hand, in the portable device 1 of this example, in addition to the holding function of the board 3, the protection function of the antenna 2 and the waterproof function of the battery take-out part are performed in the case 4 for holding the board, and the impact on the board 3 is applied. Since the function of relaxing and the function of protecting the parts housed in the decorative case 7 from impact are also performed in the case 4 for holding the substrate, the number of parts and the assembling man-hours can be reduced.
