この実施形態では、図３に示すように、第１のカメラ筐体１９を成形する第１の成形型２７と第２の成形型２９との間に転写フィルム３１が配置される。この転写フィルム３１は、一端を供給リール３３に巻回され、他端を巻取リール３５に巻回されている。そして、巻取リール３５を駆動機構(不図示)により回転することにより第１の成形型２７と第２の成形型２９との間に新たな転写フィルム３１が供給される。 Hereinafter, a method for manufacturing the first camera casing 19 and the second camera casing 21 described above will be described. In addition, since the manufacturing method of the 1st camera housing | casing 19 and the 2nd camera housing | casing 21 is fundamentally the same, in this embodiment, the manufacturing method of the 1st camera housing | casing 19 is described.
In this embodiment, as shown in FIG. 3, a transfer film 31 is disposed between a first mold 27 and a second mold 29 that mold the first camera housing 19. The transfer film 31 has one end wound around a supply reel 33 and the other end wound around a take-up reel 35. Then, a new transfer film 31 is supplied between the first mold 27 and the second mold 29 by rotating the take-up reel 35 by a drive mechanism (not shown).

転写フィルム３１は、図４に示すように、フィルム部材３１ａ、ハードコート層３１ｂ、金属薄膜層３１ｃおよび接着剤層３１ｄを有している。
フィルム部材３１ａは、可撓性を有する例えばポリエチレン樹脂からなり、２５μｍから５０μｍの肉厚を有している。ハードコート層３１ｂは、例えばアクリル樹脂からなり、１μｍ程度の肉厚を有している。金属薄膜層３１ｃは、アルミニウムからなり、０．０４μｍ程度の肉厚を有している。この金属薄膜層３１ｃは、ハードコート層３１ｂを成膜したフィルム部材３１ａにアルミニウムを蒸着することにより形成される。なお、金属薄膜層３１ｃを、銅、金、銀、ニッケル、鉄等の金属やこれらの合金をハードコート層３１ｂに蒸着して形成しても良い。接着剤層３１ｄは、例えばアクリル樹脂からなり、１μｍ程度の肉厚を有している。そして、転写フィルム３１は接着剤層３１ｄを第１の成形型２７側にして配置される。 As shown in FIG. 4, the transfer film 31 includes a film member 31a, a hard coat layer 31b, a metal thin film layer 31c, and an adhesive layer 31d.
The film member 31a is made of, for example, polyethylene resin having flexibility, and has a thickness of 25 μm to 50 μm. The hard coat layer 31b is made of, for example, an acrylic resin and has a thickness of about 1 μm. The metal thin film layer 31c is made of aluminum and has a thickness of about 0.04 μm. The metal thin film layer 31c is formed by evaporating aluminum on the film member 31a on which the hard coat layer 31b is formed. The metal thin film layer 31c may be formed by vapor-depositing a metal such as copper, gold, silver, nickel, iron, or an alloy thereof on the hard coat layer 31b. The adhesive layer 31d is made of, for example, an acrylic resin and has a thickness of about 1 μm. The transfer film 31 is arranged with the adhesive layer 31d facing the first mold 27.

図３において、第１の成形型２７に隣接して射出ノズル３７が配置されている。そして、ポリカーボネート樹脂Ｐが、射出ノズル３７のノズル部３７ａおよび第１の成形型２７のゲート部２７ａを介して、第１の成形型２７のキャビティ２７ｂに供給される。第２の成形型２９には、第１のカメラ筐体１９の内面１９ｅを形成する凸状の成形面２９ａが形成されている。この成形面２９ａには、転写フィルム３１を真空吸引する吸引穴２９ｂが形成されている。吸引穴２９ｂには、真空ポンプ(不図示)が接続されている。   In FIG. 3, an injection nozzle 37 is disposed adjacent to the first mold 27. Then, the polycarbonate resin P is supplied to the cavity 27 b of the first mold 27 through the nozzle part 37 a of the injection nozzle 37 and the gate part 27 a of the first mold 27. The second molding die 29 is formed with a convex molding surface 29 a that forms the inner surface 19 e of the first camera housing 19. A suction hole 29b for vacuum-sucking the transfer film 31 is formed on the molding surface 29a. A vacuum pump (not shown) is connected to the suction hole 29b.

この実施形態では、図５に示すように、第１のカメラ筐体１９の射出成形前に、真空ポンプ(不図示)が作動され、転写フィルム３１が第２の成形型２９の成形面２９ａに吸引される。この吸引により転写フィルム３１が成形面２９ａの形状に倣って変形する。
そして、この状態から、図６に示すように、第２の成形型２９を移動して非成形面たとえば周辺部が第１の成形型２７の非成形面に当接した状態で第１のカメラ筐体１９を射出成形する。射出成形は、ポリカーボネート樹脂Ｐをノズル部３７ａおよびゲート部２７ａを介して第１の成形型２７のキャビティ２７ｂに供給することにより行われる。この時のポリカーボネート樹脂Ｐの温度は、例えば１３０℃程度であり溶融状態にある。従って、転写フィルム３１の接着剤層３１ｄがポリカーボネート樹脂Ｐと一体化される。 In this embodiment, as shown in FIG. 5, a vacuum pump (not shown) is operated before the first camera casing 19 is injection-molded, and the transfer film 31 is placed on the molding surface 29 a of the second molding die 29. Sucked. By this suction, the transfer film 31 is deformed following the shape of the molding surface 29a.
Then, from this state, as shown in FIG. 6, the first camera is moved in a state where the second molding die 29 is moved and the non-molding surface, for example, the peripheral portion is in contact with the non-molding surface of the first molding die 27 The casing 19 is injection molded. Injection molding is performed by supplying the polycarbonate resin P to the cavity 27b of the first mold 27 through the nozzle part 37a and the gate part 27a. The temperature of the polycarbonate resin P at this time is, for example, about 130 ° C. and is in a molten state. Therefore, the adhesive layer 31d of the transfer film 31 is integrated with the polycarbonate resin P.

この状態から、図７に示すように、第２の成形型２９を移動して第１の成形型２７から離型すると、転写フィルム３１のフィルム部材３１ａのみが、ポリカーボネート樹脂Ｐから剥離する。これにより、第１のカメラ筐体１９の内面１９ｅに、転写フィルム３１の金属薄膜層３１ｃおよびハードコート層３１ｂが転写されインモールド成形が行われる。
上述した樹脂製カメラ筐体および樹脂製カメラ筐体の製造方法では、第１のカメラ筐体１９および第２のカメラ筐体２１の射出成形時に、第１のカメラ筐体１９および第２のカメラ筐体２１の内面１９ｅ，２１ｅに金属薄膜１９ｆ，２１ｆを形成するようにしたので、第１のカメラ筐体１９および第２のカメラ筐体２１に電磁波シールドを安価に施すことができる。すなわち、樹脂製の筐体にニッケル等の金属をめっきする場合には、筐体を射出成形した後に、別途めっき工程を設ける必要があるが、射出成形時に金属薄膜１９ｆ，２１ｆを形成することにより工程を削減し、電磁波シールドを安価に施すことができる。また、大規模なめっき設備が不要となり、さらに、めっき廃液による環境汚染を防止するための設備が不要になるため、電磁波シールドを安価に施すことができる。
(第２の実施形態)
以下、本発明の樹脂製カメラ筐体の製造方法の第２の実施形態について説明する。 From this state, as shown in FIG. 7, when the second mold 29 is moved and released from the first mold 27, only the film member 31 a of the transfer film 31 is peeled from the polycarbonate resin P. As a result, the metal thin film layer 31c and the hard coat layer 31b of the transfer film 31 are transferred to the inner surface 19e of the first camera housing 19, and in-mold molding is performed.
In the resin camera case and the resin camera case manufacturing method described above, the first camera case 19 and the second camera are formed during the injection molding of the first camera case 19 and the second camera case 21. Since the metal thin films 19f and 21f are formed on the inner surfaces 19e and 21e of the casing 21, the electromagnetic shielding can be applied to the first camera casing 19 and the second camera casing 21 at low cost. That is, when plating a metal such as nickel on a resin-made casing, it is necessary to provide a separate plating step after the casing is injection molded. The number of processes can be reduced, and the electromagnetic wave shield can be applied at low cost. In addition, since a large-scale plating facility is not required, and an facility for preventing environmental contamination due to plating waste liquid is not required, electromagnetic wave shielding can be performed at a low cost.
(Second Embodiment)
The second embodiment of the method for manufacturing a resin camera casing of the present invention will be described below.

なお、この実施形態において第１の実施形態と同一の部材には、同一の符号を付して詳細な説明を省略する。
この実施形態では、図８に示すように、転写フィルム３１のフィルム部材３１ａには、フィルム部材３１ａの長手方向に所定間隔を置いて転写部３１ｅが予め形成される。この転写部３１ｅは、図８のＡ−Ａ断面を示す図９に示すように、第１のカメラ筐体１９の内面１９ｅに対応する形状を有している。そして、この転写部３１ｅには、図４で示したように、フィルム部材３１ａ上に、ハードコート層３１ｂ、金属薄膜層３１ｃおよび接着剤層３１ｄが順次形成されている。 In this embodiment, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
In this embodiment, as shown in FIG. 8, a transfer portion 31e is formed in advance on the film member 31a of the transfer film 31 at a predetermined interval in the longitudinal direction of the film member 31a. The transfer portion 31e has a shape corresponding to the inner surface 19e of the first camera housing 19, as shown in FIG. In the transfer portion 31e, as shown in FIG. 4, a hard coat layer 31b, a metal thin film layer 31c, and an adhesive layer 31d are sequentially formed on the film member 31a.

この実施形態では、図１０に示すように、第１のカメラ筐体１９の射出成形前に、真空ポンプ(不図示)が作動され、転写フィルム３１のフィルム部材３１ａの転写部３１ｅが第２の成形型２９の成形面２９ａに吸引される。この吸引により転写部３１ｅが成形面２９ａに密着される。
そして、この状態から、図６に示したと同様に、第２の成形型２９を移動して第１の成形型２７とあわせた状態で第１のカメラ筐体１９を射出成形する。 In this embodiment, as shown in FIG. 10, a vacuum pump (not shown) is operated before the first camera casing 19 is injection molded, and the transfer portion 31e of the film member 31a of the transfer film 31 is moved to the second position. Suction is performed on the molding surface 29 a of the molding die 29. By this suction, the transfer portion 31e is brought into close contact with the molding surface 29a.
From this state, similarly to the case shown in FIG. 6, the first camera casing 19 is injection-molded in a state in which the second mold 29 is moved and combined with the first mold 27.

なお、図１０において、図示を省略したが、転写フィルム３１は比較的大径の供給リールおよび巻取リールに巻回されている。
この実施形態では、フィルム部材３１ａに第１のカメラ筐体１９の内面１９ｅに対応する形状の転写部３１ｅを形成した後、転写部３１ｅに金属薄膜層３１ｃ等を形成して転写フィルム３１を製造するようにしたので、転写部３１ｅを第２の成形型２９の成形面２９ａに吸引した時に、金属薄膜層３１ｃが変形することがなくなる。従って、第１のカメラ筐体１９の内面１９ｅに金属薄膜１９ｆを高い精度で形成することができる。 Although not shown in FIG. 10, the transfer film 31 is wound around a relatively large diameter supply reel and take-up reel.
In this embodiment, after forming a transfer portion 31e having a shape corresponding to the inner surface 19e of the first camera housing 19 on the film member 31a, a metal thin film layer 31c or the like is formed on the transfer portion 31e to manufacture the transfer film 31. As a result, the metal thin film layer 31 c is not deformed when the transfer portion 31 e is sucked into the molding surface 29 a of the second mold 29. Therefore, the metal thin film 19f can be formed on the inner surface 19e of the first camera housing 19 with high accuracy.

また、第１のカメラ筐体１９の開口端面から前面部１９ａまでの深さが大きい場合にも、第１のカメラ筐体１９のコーナー部に配置される金属薄膜層３１ｃに無理な変形が生じることがなくなり、第１のカメラ筐体１９の内面１９ｅに金属薄膜１９ｆを高い精度で形成することができる。
(実施形態の補足事項)
以上、本発明を上述した実施形態によって説明してきたが、本発明の技術的範囲は上述した実施形態に限定されるものではなく、例えば、以下のような形態でも良い。 Further, even when the depth from the opening end surface of the first camera housing 19 to the front surface portion 19a is large, the metal thin film layer 31c disposed at the corner portion of the first camera housing 19 is deformed unreasonably. Thus, the metal thin film 19f can be formed on the inner surface 19e of the first camera housing 19 with high accuracy.
(Supplementary items of the embodiment)
