Outline of the Invention) The housing of the electronic device according to the present invention is an internal structure that includes an external structure that forms the front part or part of a substantially box-shaped housing and a board holding portion for holding at least a circuit board. In a housing of an electronic device in which a structure is integrally formed of a synthetic resin, an external structure integrally includes at least one side of an upper housing part and one side of a lower housing part via a hinge part. The substrate holding part is integrally connected to the other side of the upper housing part via a hinge part, and the substrate holding part is folded to the upper housing part with the hinge part as a rotation center. By making it possible to engage with the upper housing portion with, and by allowing the upper housing portion to be engaged with the lower housing portion in a state of being folded with respect to the lower housing portion with the hinge portion as the center of rotation, The manufacturing cost of this type of equipment can be greatly reduced and the assembly work can be performed easily. Come, and, in which to be able to dimensional accuracy more uniform between each member.
（C.背景技術） 例えば、ラジオ受信機やテープレコーダ等の電子機器に
おいては、通常、キャビネットあるいはケーシング等と
称される略箱形を成す筐体を有すると共に、該筐体の内

種の部材あるいは機構が装着されたメカシャーシ、電池
収納部、カセット装着部等が設けられ、更には、上記電
池収納部あるいはカセット装着部を開閉する蓋部材が筐
体の一部を成す形態を有して設けられることが多い。(C. Background Art) For example, an electronic device such as a radio receiver or a tape recorder usually has a substantially box-shaped casing called a cabinet or a casing, and a predetermined casing is provided inside the casing. There are provided one or more circuit boards on which circuits are formed, a mechanical chassis on which various members or mechanisms are mounted, a battery storage portion, a cassette mounting portion, and the like, and further, the battery storage portion or the cassette mounting portion is opened and closed. The lid member is often provided so as to have a form forming a part of the housing.
そこで、電子機器を構成する各部を筐体及びこれに属す
る部材等からなる部分とそれ以外の部分とにグループ分
けする外部構造体と内部構造体とに大別することができ
る。即ち、外部構造体とは筐体又は筐体及びその一部を
成す蓋部材等から成る外側の構造部分であり、また、内
部構造体とは回路基板及びこれを保持するための基板保
持部やメカシャーシ等から成る内側の構造部分である。Therefore, the respective parts constituting the electronic device can be roughly classified into an external structure and an internal structure which are grouped into a part including a housing and members belonging to the case and the other parts. That is, the external structure is a housing or an outer structural portion including a housing and a lid member that forms a part of the housing, and the internal structure is a circuit board and a board holding portion for holding the circuit board. It is an inner structural part composed of a mechanical chassis and the like.
そして、このような外部構造体は、近時、その多くのも
のが合成樹脂により形成されると共に、筐体はケースハ
ーフ等と称される複数の部分筐体を成形用金型により各
別に成形し、それを互いに一体的に結合することにより
略箱形の筐体を成すように構成され、また、内部構造体
も、外部構造体とは別体に形成され、それを外部構造体
に組み込むように構成されている。Most of these external structures are recently made of synthetic resin, and the housings are formed by molding a plurality of partial housings called case halves, etc. Then, they are integrally joined to each other to form a substantially box-shaped housing, and the internal structure is formed separately from the external structure, and is incorporated into the external structure. Is configured.
（D.考案が解決しようとする問題点） このように、従来の電子機器はその外部構造体と内部構
造体とが別体に形成され、しかも、外部構造体及び内部
構造体はそれぞれ複数の部品により構成されていたの
で、その部品点数が非常に多いものになるという問題を
有している。(D. Problems to be Solved by the Invention) As described above, in the conventional electronic device, the external structure and the internal structure are separately formed, and the external structure and the internal structure each have a plurality of parts. Since it is composed of parts, there is a problem that the number of parts is very large.
特に合成樹脂により形成される所謂モールド部品の数が
多ければ、その部品の数と同じ数の成形用金型が必要に
なる。周知の通り、成形用金型のコストは電子機器の製
造コストの中で非常に大きな役割を占めるので、これら
金型の数は電子機器のコストを下げる上で極めて重要な
要素となっている。In particular, if the number of so-called molded parts made of synthetic resin is large, as many molding dies as the number of the parts are required. As is well known, since the cost of the molding die plays a very large role in the manufacturing cost of the electronic device, the number of these molds is an extremely important factor in reducing the cost of the electronic device.
そして、部品点数が多ければ、その分組立工数も多くな
り、かつ、部品管理にも多くの手間を必要とし、また、
自動組立機による組立を困難なものにする原因にもなる
等の問題がある。And, if the number of parts is large, the number of assembling man-hours will increase, and the parts management also requires a lot of labor.
There are problems such as making it difficult to assemble with an automatic assembler.
更には、成形用金型によって形成される部材の寸法精度
は使用される金型が異なると微妙に相違するので、異な
る金型によって形成される部材の数が多くなればなる
程、各部材間の寸法精度のバラツキも大きくなり、場合
によっては組立や動作に支障を来たすことも生じて来る
という問題もある。Furthermore, the dimensional accuracy of the members formed by the molding dies is slightly different when the dies used are different. Therefore, as the number of members formed by different dies increases, There is also a problem that the dimensional accuracy of the device becomes large and the assembly and operation may be hindered in some cases.
尚、機器を構成する部材のうちの複数のものを一体に形
成することによって部品点数を削減するようにしたもの
として、例えば、実開昭57−61877号公報に示されたも
のがあるが、これは筐体の一部を構成する部分ケースと
所謂電池蓋とを一体に形成したもの、即ち、いわば、外
部構造体を単一の部品として形成するようにしたもので
あり、このような構造では、部品点数を大幅に削減する
ことに充分に寄与することはできない。Incidentally, as a means for reducing the number of parts by integrally forming a plurality of members constituting the device, for example, there is one shown in Japanese Utility Model Laid-Open No. 57-61877, This is one in which a partial case that constitutes a part of a housing and a so-called battery lid are integrally formed, that is, an external structure is formed as a single component. Then, it is not possible to sufficiently contribute to a significant reduction in the number of parts.

他の一の辺にヒンジ部を介して一体に連結し、基板保持
部はヒンジ部を回動中心として上側筐体部に折り畳んだ
状態で上側筐体部に係止可能にすると共に、該上側筐体
部はヒンジ部を回動中心として下側筐体部に折り畳んだ
状態で下側筐体部に係止可能にしたものである。(E. Means for Solving Problems) In order to solve the above-mentioned problems, the housing of the electronic device of the present invention is at least an external structure that constitutes all or part of a substantially box-shaped housing. In a housing of an electronic device in which an internal structure including a board holding portion for holding a circuit board is integrally formed of synthetic resin, the external structure is at least one side of the upper housing portion and the lower housing. One side of the body part is integrally connected via a hinge part, the substrate holding part is integrally connected to another side of the upper housing part via a hinge part, and the substrate holding part is a hinge. The upper housing part can be locked to the upper housing part in a state of being folded in the upper housing part about the rotation center, and the upper housing part can be folded in the lower housing part around the hinge part as a rotation center. The lower housing can be locked.
従って、本考案によれば、筐体の全部又は一部を構成す
る外部構造体と該外部構造体の内部に配置されるべき内
部構造体とを互いに折り畳み可能で折り畳むと略箱形の
筐体になる単一部品の構造を有する部材１個で構成する
ことができる。Therefore, according to the present invention, the external structure forming the whole or a part of the housing and the internal structure to be disposed inside the external structure are foldable with respect to each other. It can be composed of one member having the structure of a single component.
