PROBLEM TO BE SOLVED: To keep firm fitting of cases with respect to an impact of falling, etc. and also to facilitate release of fitting of cases in maintenance, etc.SOLUTION: A portable unit 100 includes: an upper case 1; a lower case 2; multiple projected engagement parts 1e-1h arranged in peripheral edges 1a-1d of the upper case 1; multiple recessed engagement parts 2e-2h arranged in peripheral edges 2a-2d of the lower case 2 so as to correspond to the projected engagement parts 1e-1h; a circuit board 5; and a battery 8. The respective projected engagement parts 1e-1h are engaged with the respective recessed engagement parts 2e-2h so as to allow both of the cases 1, 2 to be fitted. Then, the circuit board 5 and the battery 8 are stored in an internal space enclosed by the cases 1, 2. An engagement amount of the specific projected engagement parts 1h with the recessed engagement part 2h is larger than engagement amounts of the other projected engagement parts 1e-1g with the recessed engagement parts 2e-2g.SELECTED DRAWING: Figure 1
【課題】落下時の衝撃などに対してケース同士の嵌合を強固に保つ一方で、保守時などにはケース同士の嵌合を解除し易くする。【解決手段】携帯機１００は、上ケース１と、下ケース２と、上ケース１の周縁部１ａ〜１ｄに複数設けられた凸形係合部１ｅ〜１ｈと、該凸形係合部１ｅ〜１ｈと対応するように下ケース２の周縁部２ａ〜２ｄに複数設けられた凹形係合部２ｅ〜２ｈと、回路基板５と、電池８とを備える。各凸形係合部と１ｅ〜１ｈと各凹形係合部２ｅ〜２ｈとが係合することにより、両ケース１、２が嵌合されて、該両ケース１、２で囲まれた内部空間に回路基板５と電池８が収納されている。そして、特定の凸形係合部１ｈと凹形係合部２ｈとの係合量は、他の凸形係合部１ｅ〜１ｇと凹形係合部２ｅ〜２ｇとの係合量より大きくなっている。【選択図】図１
