Description

バッテリ室34に放熱器100が装填されると、放熱器100の突出部(ヒートシンク112の突出部112C)が、バネ52の付勢力に抗して、第2板金48を押圧し、第2板金48を移動させる。移動した第2板金48は、第1板金当接部44Bに当接して停止する。第2板金48が突出部112C押されて第1板金当接部44Bに当接することにより、第1板金44とヒートシンク112とが、第2板金48を介して熱的に接続される。これにより、第1板金44からヒートシンク112への放熱経路が形成される。また、これにより、放熱が促進され、カメラボディ10の内部の熱が外部に放熱される。 When the radiator 100 is loaded into the battery chamber 34, the projecting portion of the radiator 100 (the projecting portion 112C of the heat sink 112) presses the second metal plate 48 against the biasing force of the spring 52, and the second metal plate 48 is pressed. 48 is moved. The moved second sheet metal 48 comes into contact with the first sheet metal contact portion 44B and stops. The first metal plate 44 and the heat sink 112 are thermally connected via the second metal plate 48 when the second metal plate 48 is pushed by the protruding portion 112</b>C and comes into contact with the first metal plate contact portion 44</b>B. Thereby, a heat radiation path from the first metal plate 44 to the heat sink 112 is formed. Further, this promotes heat dissipation, and the heat inside the camera body 10 is radiated to the outside.

[変形例]
(1)第1板金及び第2板金の熱伝導率の関係
第1板金44及び第2板金48については、熱伝導率の関係を次のように設定することが好ましい。すなわち、第2板金48の熱伝導率を第1板金44の熱伝導率よりも高く設定する。これにより、より多くの熱が放熱器100の方に流れ、熱源から発生する熱を外部に効率的に放熱できる。これに加え、放熱器側に多くの熱が流れるため、カメラボディ10の外装(特に、背面側の外装)に流れる熱が少なくなり、外装の温度情報を抑制できる。このような熱伝導率の関係にするには、たとえば、第1板金44をアルミニウムで構成し、第2板金48をで構成する。
[Modification]
(1) Relationship between Thermal Conductivity of First Metal Sheet and Second Metal Sheet For the first metal sheet 44 and second metal sheet 48, it is preferable to set the thermal conductivity relationship as follows. That is, the thermal conductivity of the second metal plate 48 is set higher than the thermal conductivity of the first metal plate 44 . As a result, more heat flows toward the radiator 100, and the heat generated from the heat source can be efficiently radiated to the outside. In addition, since more heat flows to the radiator side, less heat flows to the exterior of the camera body 10 (particularly, the exterior on the back side), and the temperature information of the exterior can be suppressed. To achieve such a thermal conductivity relationship, for example, the first sheet metal 44 is made of aluminum and the second sheet metal 48 is made of copper .

同図に示すように、バッテリ挿入口32にバッテリ保持爪72を有し、このバッテリ保持爪72でバッテリ室34に装填されたバッテリ200及び放熱器100を保持する。バッテリ保持爪72は、軸72Aを揺動中心として、ロック位置とアンロック位置との間を揺動する。バッテリ保持爪72は、ロック位置において、先端の爪部が、バッテリ挿入口32に突出し、バッテリ室34に装填されたバッテリ200及び放熱器100に係合する。また、バッテリ保持爪72は、アンロック位置において、先端の爪部がバッテリ挿入口32から退避し、バッテリ室34に装填されたバッテリ200及び放熱器100の取り出しが可能になる。バッテリ保持爪72は、図示しないバネによって、ロック位置に向けて付勢される。 As shown in the figure, the battery insertion opening 32 has battery holding claws 72 which hold the battery 200 and radiator 100 loaded in the battery chamber 34 . The battery holding claw 72 swings between the lock position and the unlock position about the shaft 72A. At the locked position, the claw portion at the tip of the battery holding claw 72 protrudes into the battery insertion opening 32 and engages the battery 200 and the radiator 100 loaded in the battery chamber 34 . At the unlocked position, the claw portion at the tip of the battery holding claw 72 is retracted from the battery insertion opening 32, so that the battery 200 and the radiator 100 loaded in the battery chamber 34 can be taken out. The battery holding claw 72 is biased toward the locked position by a spring (not shown).

放熱スリット90Aは、第2板金48第1板金当接部44Bに当接する位置(第1位置)に移動すると、開けられる。図21に示すように、スリット板94に備えられた各通気スリット94Aは、第2板金48が第1板金当接部44Bに当接する位置(第1位置)に位置すると、放熱スリット90A上に位置する。これにより、放熱スリット90Aが開放され、カメラボディ10の内部と外部とが連通される。 The heat radiation slit 90A is opened when the second metal sheet 48 moves to the position (first position) where the second metal sheet 48 contacts the first metal sheet contact portion 44B. As shown in FIG. 21, each ventilation slit 94A provided in the slit plate 94 is positioned above the heat radiation slit 90A when the second metal plate 48 is positioned at the position (first position) where the second metal plate 48 contacts the first metal plate contact portion 44B. To position. As a result, the heat radiation slit 90A is opened, and the inside and the outside of the camera body 10 are communicated with each other.

図23に示すように、バッテリ室34に放熱器100が装填されると、放熱器100の突出部(ヒートシンク112の突出部112C)が、第2板金48を押圧し、第1板金当接部44Bに当接する。これにより、第1板金44からヒートシンク112への放熱経路が形成され、放熱機能がオンされる。 As shown in FIG. 23, when the radiator 100 is loaded into the battery chamber 34, the projecting portion of the radiator 100 (the projecting portion 112C of the heat sink 112) presses the second metal plate 48, and the contact portion of the first metal plate 44B . As a result, a heat dissipation path is formed from the first metal plate 44 to the heat sink 112, and the heat dissipation function is turned on.
