まず、録画再生装置 100の動作として、筐体 300の製造工程のうち外装ケース 310 の製造工程について説明する。外装ケース 310を製造するに当り、鋼板を所定の形 状に打ち抜き加工する。そして、打ち抜いた鋼板をプレス加工して、外装ケース側通 気孔 311Aに対応する切れ込みを形成すると共に、ねじ頭収容部 312A, 313Aを 全て同一方向に突出形成する。この後、打ち抜いた鋼板の所定の部位にねじ穴 311 B, 312A1, 313A1を全て同一の方向に向けて穿孔形成する。さらに、図 2に示す ような状態に鋼板を折り曲げ、第 1の側面部 312および第 2の側面部 313を天板部 3 11に略直交する状態に立ち上げて、外装ケース 310が完成する。  First, as an operation of the recording / reproducing apparatus 100, a manufacturing process of the outer case 310 among manufacturing processes of the housing 300 will be described. In manufacturing the outer case 310, a steel plate is punched into a predetermined shape. Then, the punched steel sheet is pressed to form a notch corresponding to the outer case side air hole 311A, and the screw head accommodating portions 312A and 313A are formed to protrude in the same direction. Thereafter, the screw holes 311 B, 312A1, and 313A1 are all drilled in the same direction in predetermined portions of the punched steel sheet. Further, the steel plate is bent in a state as shown in FIG. 2, and the first side surface portion 312 and the second side surface portion 313 are raised to a state substantially orthogonal to the top plate portion 311 to complete the outer case 310.
[0038] 次に、シャーシ 330を製造するに当り、鋼板を所定の形状に打ち抜き加工する。そ して、打ち抜いた鋼板をプレス加工して、台座部側通気孔 331 Aに対応する切れ込 みを形成すると共に、凹部 334や、載置部 331B、保持部材取付部 331Cなどを全て 同一方向に突出形成する。また、打ち抜いた鋼板における端板部 332の各種端子 に対応する部位に、図示しない端子穴を形成する。この後、打ち抜いた鋼板の所定 の部位に、ねじ穴 333A, 334A1, 335Aを凹部 334などの突出方向と同一の方向 に向けて穿孔形成する。さらに、プレス加工により、図 2に示すような状態に鋼板を折 り曲げ、端板部 332、第 1の折曲部 333および第 2の折曲部 335を台座部 331に略 直交する状態に立ち上げて、シャーシ 330が完成する。  [0038] Next, in manufacturing the chassis 330, a steel plate is punched into a predetermined shape. The punched steel plate is then pressed to form a notch corresponding to the pedestal side air hole 331A, and the recess 334, the mounting portion 331B, the holding member mounting portion 331C, etc. are all in the same direction. Protrusively formed. Further, terminal holes (not shown) are formed in portions corresponding to various terminals of the end plate portion 332 in the punched steel plate. Thereafter, screw holes 333A, 334A1, and 335A are drilled in predetermined portions of the punched steel sheet in the same direction as the protruding direction of the recesses 334 and the like. Further, the steel plate is bent into a state as shown in FIG. 2 by pressing, so that the end plate portion 332, the first bent portion 333, and the second bent portion 335 are substantially orthogonal to the pedestal portion 331. The chassis 330 is completed.
[0039] さらに、保持部材 340を製造するに当り、打ち抜き加工により略長尺矩形状の鋼板 を形成しておく。そして、打ち抜いた鋼板の所定の部位に、ねじ穴 341A, 342A, 3 43Aに対応するシャーシ側通気孔を全て同一の方向に向けて穿孔形成する。さらに 、図 2に示すように、鋼板を折り曲げて保持部材側当接面部 341、シャーシ側取付部 342および外装ケース側取付部 343を形成し、保持部材 340が完成する。 [0040] (DVDドライブ本体 200の筐体 300内部への組み付け） [0039] Further, in manufacturing the holding member 340, a substantially long rectangular steel plate is formed by punching. Then, the chassis side air holes corresponding to the screw holes 341A, 342A, and 343A are all drilled and formed in predetermined portions of the punched steel sheet in the same direction. Further, as shown in FIG. 2, the steel plate is bent to form the holding member side contact surface portion 341, the chassis side mounting portion 342, and the exterior case side mounting portion 343, and the holding member 340 is completed. [0040] (Assembly of DVD drive body 200 inside housing 300)
次に、録画再生装置 100の動作として、 DVDドライブ本体 200の筐体 300内部へ の組み付けについて図面に基づいて説明する。まず、 DVDドライブ本体 200におけ るケース体 210の他方の側面 212に保持部材 340の保持部材側当接面部 341を当 接してねじ 341Bをねじ穴 341A, 212Aに螺合することにより、ケース体 210の他方 の側面 212に保持部材 340を取り付ける。そして、図 2に示すように、保持部材 340 が取り付けられた DVDドライブ本体 200を、シャーシ 330における台座部 331の載 置部 331Bに載置する。  Next, as an operation of the recording / reproducing apparatus 100, assembly of the DVD drive main body 200 into the housing 300 will be described with reference to the drawings. First, the holding member side abutment surface portion 341 of the holding member 340 is brought into contact with the other side surface 212 of the case body 210 in the DVD drive main body 200, and the screw 341B is screwed into the screw holes 341A and 212A. A holding member 340 is attached to the other side surface 212 of 210. Then, as shown in FIG. 2, the DVD drive main body 200 to which the holding member 340 is attached is placed on the placement portion 331 B of the base portion 331 in the chassis 330.
[0041] この後、台座部 331の保持部材取付部 331Cに、保持部材 340のシャーシ側取付 部 342をねじ 342Bにて取り付ける。さらに、図 3に示すように、第 1の折曲部 333のシ ヤーシ側当接面 334Aに DVDドライブ本体 200におけるケース体 210の一方の側面 211を当接させた状態で、ねじ 334A2をねじ穴 334A2, 211A〖こ螺合する。これに より、 DVDドライブ本体 200がシャーシ 330および保持部材 340により保持される。 なお、この状態において、図 4に示すように、第 1の折曲部 333とケース体 210におけ る一方の側面 211とが所定の幅寸法だけ離間した状態となって、ここに放熱空間 H が形成されている。  [0041] Thereafter, the chassis side mounting portion 342 of the holding member 340 is attached to the holding member mounting portion 331C of the pedestal portion 331 with the screw 342B. Further, as shown in FIG. 3, the screw 334A2 is screwed in a state where the one side surface 211 of the case body 210 in the DVD drive main body 200 is in contact with the chassis side contact surface 334A of the first bent portion 333. Holes 334A2, 211A are screwed together. As a result, the DVD drive main body 200 is held by the chassis 330 and the holding member 340. In this state, as shown in FIG. 4, the first bent portion 333 and the one side surface 211 of the case body 210 are separated from each other by a predetermined width dimension. Is formed.
[0042] DVDドライブ本体 200を取り付けた後、制御装置を台座部 331に配設して制御装 置と DVD処理装置とを接続し、端板部 332の図示しない端子穴に各種端子を配設 する。そして、化粧板 320をシャーシ 330の前面側に取り付け、制御装置と化粧板 32 0における各部とを接続する。この後、外装ケース 310にて、 DVDドライブ本体 200、 制御装置、シャーシ 330および保持部材 340を覆う。そして、ねじ 312B, 313Bをそ れぞれ螺合して、外装ケース 310をシャーシ 330に取り付けることにより、録画再生装 置 100が完成する。なお、第 1の折曲部 333と外装ケース 310における第 1の側面部 312とをねじ 312Bにて取り付ける際、第 1の折曲部 333とケース体 210における一 方の側面 211との間には放熱空間 Hが形成されているので、ねじ穴 333Aから保持 部材 340に対向する方向へ突出した複数のねじ 312Bの先端がケース体 210の一 方の側面 211に突き当たることがな!、。  [0042] After installing the DVD drive main body 200, the control device is disposed on the base portion 331 to connect the control device and the DVD processing device, and various terminals are disposed in terminal holes (not shown) of the end plate portion 332. To do. Then, the decorative plate 320 is attached to the front side of the chassis 330, and the control device and each part of the decorative plate 320 are connected. Thereafter, the outer case 310 covers the DVD drive main body 200, the control device, the chassis 330, and the holding member 340. Then, the screws 312B and 313B are screwed together and the outer case 310 is attached to the chassis 330, whereby the recording / reproducing apparatus 100 is completed. When the first bent portion 333 and the first side surface portion 312 of the outer case 310 are attached with the screws 312B, the first bent portion 333 and the one side surface 211 of the case body 210 are interposed between them. Since the heat dissipating space H is formed, the tips of the plurality of screws 312B protruding in the direction opposite to the holding member 340 from the screw holes 333A do not hit one side surface 211 of the case body 210!
[0043] (凹部 334の作用） そして、録画再生装置 100の動作として、凹部 334の作用について図面に基づい て説明する。まず、図 1に示すように、録画再生装置 100を台座部 331が載置面に当 接される状態で載置しておく。そして、利用者にて化粧板 320の電源スィッチ 322が 操作されることにより、録画再生装置 100の電源が ONの状態となる。この状態にお いて、各種操作スィッチ 323が操作されることにより、 DVDドライブ本体 200にて録画 処理または再生処理が実施される。 [0043] (Operation of recess 334) Then, as an operation of the recording / reproducing apparatus 100, an operation of the recess 334 will be described with reference to the drawings. First, as shown in FIG. 1, the recording / reproducing apparatus 100 is placed with the pedestal 331 in contact with the placement surface. Then, when the user operates the power switch 322 of the decorative plate 320, the power of the recording / playback apparatus 100 is turned on. In this state, when the various operation switches 323 are operated, the DVD drive main body 200 performs recording processing or playback processing.
[0044] この際、 DVDドライブ本体 200による録画処理または再生処理に伴って熱が発生 する。そして、 DVDドライブ本体 200で発生した熱が図 4に示す放熱空間 Hに伝播 する。また、 DVDドライブ本体 200は載置部 331Bに載置されて台座部 331より離間 した状態となっているので、台座部側通気孔 331 Aから外気が導入される。そして、 D VDドライブ本体 200で発生した熱は導入された外気と共に放熱空間 Hにおける鉛 直方向上側に移動し、外装ケース側通気孔 311 Aを通って装置外部に放出される。 また、この時、第 1の折曲部 333と第 1の側面部 312との間には間隙 Kが形成されて いるので、 DVDドライブ本体 200で発生した熱が外装ケース 310における第 1の側 面部 312に直接伝わることが防止される。  At this time, heat is generated along with the recording process or the reproduction process by the DVD drive main body 200. Then, the heat generated in the DVD drive main body 200 propagates to the heat dissipation space H shown in FIG. Further, since the DVD drive main body 200 is placed on the placement portion 331B and is separated from the pedestal portion 331, outside air is introduced from the pedestal portion side vent hole 331A. Then, the heat generated in the DVD drive main body 200 moves together with the introduced outside air to the upper side in the lead direction in the heat radiation space H, and is released to the outside of the apparatus through the exterior case side vent hole 311A. At this time, since a gap K is formed between the first bent portion 333 and the first side surface portion 312, the heat generated in the DVD drive main body 200 is generated on the first side of the outer case 310. Direct transmission to the face portion 312 is prevented.
[0045] また、 DVDドライブ本体 200にて録画処理または再生処理が実施されることにより 、 DVD処理装置より電磁波が発生しこれに伴ってケース体 210に高周波電流が流 れる。ここで、シャーシ側当接面 334Aおよび保持部材側当接面部 341は DVDドラ イブ本体 200におけるケース体 210にそれぞれ当接されている。また、シャーシ側当 接面 334Aのねじ穴 334A1周縁に形成されたバリと、保持部材側当接面部 341の ねじ穴 341A周縁に形成されたバリとは、ねじ 334A2, 341Bがケース体 210の一方 の側面 211に螺合されることによりケース体 210の両側面 211, 212に食い込む状態 となっている。これにより、 DVD処理装置より発生した高周波電流は、シャーシ側当 接面 334Aおよび保持部材側当接面部 341に確実に伝達し、これら部材を介してシ ヤーシ 330に確実にアースされる。  [0045] Further, when the DVD drive main body 200 performs a recording process or a reproduction process, an electromagnetic wave is generated from the DVD processing apparatus, and accordingly, a high-frequency current flows through the case body 210. Here, the chassis side contact surface 334A and the holding member side contact surface portion 341 are in contact with the case body 210 of the DVD drive main body 200, respectively. In addition, the burr formed on the periphery of the screw hole 334A1 of the chassis side contact surface 334A and the burr formed on the periphery of the screw hole 341A of the holding member side contact surface portion 341 include screws 334A2 and 341B that are one side of the case body 210. By being screwed onto the side surface 211 of the case body 210, the case body 210 is in a state of biting into both side surfaces 211 and 212. As a result, the high-frequency current generated by the DVD processing apparatus is reliably transmitted to the chassis-side contact surface 334A and the holding member-side contact surface portion 341, and is reliably grounded to the chassis 330 via these members.
[0046] 〔録画再生装置の作用効果〕  [Operation and effect of recording / playback apparatus]
上述したように、上記実施の形態では、録画再生装置 100に、 DVD処理部をケー ス体 210内に収容した DVDドライブ本体 200と、この DVDドライブ本体 200を内部 に収容する筐体 300とを設けている。そして、筐体 300に、台座部 331、および、ケ ース体 210が取り付けられる第 1の折曲部 333を備えたシャーシ 330を設けている。 また、筐体 300に、第 1の折曲部 333と対向する状態で台座部 331に取り付けられ、 ケース体 210が取り付けられて DVDドライブ本体 200を第 1の折曲部 333とにて保 持する保持部材 340を設けている。このため、 DVDドライブ本体 200を筐体 300に 組み付ける際、第 1の折曲部 333および保持部材 340で DVDドライブ本体 200のケ ース体 210を挟み、例えばねじなどを用いて DVDドライブ本体 200を筐体 300に固 定することができる。これにより、シャーシ 330の側面である第 1の折曲部 333を利用 することで、 DVDドライブ本体 200を筐体 300に固定するための部材が保持部材 34 0のみで済むので、従来よりも部品点数および組み付け工数を大幅に削減することが できる。したがって、筐体 300内部に DVDドライブ本体 200を容易に組み付けること ができ、製造効率の向上に寄与することができる。 As described above, in the above-described embodiment, the recording / playback apparatus 100 includes the DVD drive main body 200 in which the DVD processing unit is housed in the case body 210 and the DVD drive main body 200 inside. A housing 300 is provided. The chassis 300 is provided with a chassis 330 including a pedestal portion 331 and a first bent portion 333 to which the case body 210 is attached. In addition, the housing 300 is attached to the pedestal 331 so as to face the first bent portion 333, and the case body 210 is attached to hold the DVD drive main body 200 with the first bent portion 333. A holding member 340 is provided. For this reason, when assembling the DVD drive main body 200 to the housing 300, the case body 210 of the DVD drive main body 200 is sandwiched between the first bent portion 333 and the holding member 340, and the DVD drive main body 200 using, for example, a screw or the like. Can be fixed to the housing 300. As a result, by using the first bent portion 333 that is the side surface of the chassis 330, the member for fixing the DVD drive main body 200 to the housing 300 is only the holding member 340. The number of points and assembly man-hours can be greatly reduced. Therefore, the DVD drive main body 200 can be easily assembled in the housing 300, which can contribute to an improvement in manufacturing efficiency.
[0047] また、筐体 300に、シャーシ 330の外部を覆う外装ケース 310と、第 1の折曲部 333 の外側に設けられた凹部 334と、凹部 334に設けられた DVDドライブ本体 200をね じ 334A2にて取り付けるねじ穴 334A1とを設けている。このため、 DVDドライブ本体 200を第 1の折曲部 333に取り付けた取付位置が、外装ケース 310を第 1の折曲部 3 33に取り付けた取付位置よりも、装置の内部側に奥まった状態となっているので、例 えば、外装ケース 310を第 1の折曲部 333に取り付けた際にねじ 312Bの先端部が D VDドライブ本体 200のケース体 210に突き当たることを回避することができる。  [0047] In addition, an outer case 310 covering the outside of the chassis 330, a recess 334 provided outside the first bent portion 333, and a DVD drive main body 200 provided in the recess 334 are connected to the housing 300. Screw holes 334A1 to be attached at 334A2 are provided. For this reason, the installation position where the DVD drive main body 200 is attached to the first bent portion 333 is deeper inside the device than the attachment position where the outer case 310 is attached to the first bent portion 333. Therefore, for example, when the exterior case 310 is attached to the first bent portion 333, it is possible to avoid the tip portion of the screw 312B from hitting the case body 210 of the DVD drive main body 200.
[0048] そして、シャーシ 330の第 1の折曲部 333に、この第 1の折曲部 333の一部が保持 部材 340と対向する方向に所定の高さを有した状態で突出形成された凹部 334を設 けている。これにより、第 1の折曲部 333とケース体 210における一方の側面 211とが 所定の幅寸法だけ離間した状態となっており、ここに放熱空間 Hが形成されている。 そして、凹部 334にケース体 210を取り付け、第 1の折曲部 333におけるねじ穴 333 Aに外装ケース 310の第 1の側面部 312をねじ 312Bにて取り付けている。この際、 ねじ 312Bの先端を切断するなどの処理をせずとも、第 1の折曲部 333とケース体 21 0における一方の側面 211との間に充分なスペースが確保できているので、第 1の折 曲部 333から保持部材 340に対向する方向へ突出したねじ 312Bの先端がケース体 210の一方の側面 211に突き当たることを防ぐことができる。また、第 1の折曲部 333 とケース体 210における一方の側面 211とが所定の幅寸法だけ離間することにより形 成された放熱空間 Hから、 DVDドライブ本体 200で発生した熱を放熱することができ る。したがって、第 1の折曲部 333に凹部 334を設けたことにより、 DVDドライブ本体 200を筐体 300に固定するためにシャーシ 330の第 1の折曲部 333を利用すること が可能となり、かつ、外装ケース 310をシャーシ 330に取り付ける際にねじ 312Bの先 端がケース体 210の側面 211に突き当たってしまう不具合も同時に解決することがで きる。さらに、 DVDドライブ本体 200で発生した熱を放熱空間 Hに発散することがで きる。 Then, a part of the first bent portion 333 is formed to protrude from the first bent portion 333 of the chassis 330 with a predetermined height in a direction facing the holding member 340. A recess 334 is provided. As a result, the first bent portion 333 and the one side surface 211 of the case body 210 are separated from each other by a predetermined width dimension, and a heat dissipation space H is formed here. The case body 210 is attached to the recess 334, and the first side surface portion 312 of the outer case 310 is attached to the screw hole 333A in the first bent portion 333 with the screw 312B. At this time, a sufficient space can be secured between the first bent portion 333 and the one side surface 211 of the case body 210 without performing processing such as cutting the tip of the screw 312B. Screws protruding in the direction facing the holding member 340 from the bent portion 333 of 1 The tip of the 312B is the case body It can prevent hitting one side 211 of 210. Further, heat generated in the DVD drive main body 200 is radiated from the heat radiation space H formed by separating the first bent portion 333 and the one side surface 211 of the case body 210 by a predetermined width dimension. You can. Therefore, by providing the concave portion 334 in the first bent portion 333, the first bent portion 333 of the chassis 330 can be used to fix the DVD drive main body 200 to the housing 300, and In addition, when the exterior case 310 is attached to the chassis 330, the problem that the tip of the screw 312B hits the side surface 211 of the case body 210 can be solved at the same time. Furthermore, the heat generated in the DVD drive main body 200 can be dissipated into the heat dissipation space H.
[0049] また、凹部 334は、第 1の折曲部 333に平行に形成されたシャーシ側当接面 334A を有している。このため、立方体状のケース体 210における一方の側面 211に対して 、シャーシ側当接面 334Aの全面を当接することができるので、 DVDドライブ本体 20 0を安定して保持することができる。  In addition, the recess 334 has a chassis-side contact surface 334A formed in parallel to the first bent portion 333. Therefore, the entire chassis side contact surface 334A can be brought into contact with one side surface 211 of the cubic case body 210, so that the DVD drive main body 200 can be stably held.
[0050] そして、凹部 334の一部にシャーシ側通気孔 334Cを設け、外装ケース 210の凹部 334に対向する位置に外装ケース側通気孔 311Aを設けている。このため、 DVDド ライブ本体 200で発生した熱が放熱空間 Hに伝播した際、 DVDドライブ本体 200で 発生した熱はシャーシ側通気孔 334Cを通過して放熱空間 Hにおける鉛直方向上側 に移動し、外装ケース側通気孔 311 Aを通って装置外部に放出される。したがって、 シャーシ側通気孔 334Cを設けることで、凹部 334が放熱の際の障害となることを防 ぎ、 DVDドライブ本体 200で発生した熱を効果的に放熱することができる。  [0050] Then, a chassis-side vent hole 334C is provided in a part of the recess 334, and an exterior case-side vent hole 311A is provided at a position facing the recess 334 of the exterior case 210. For this reason, when the heat generated in the DVD drive main body 200 propagates to the heat dissipation space H, the heat generated in the DVD drive main body 200 passes through the chassis-side vent hole 334C and moves upward in the vertical direction in the heat dissipation space H. It is discharged to the outside through the outer case side vent hole 311 A. Therefore, by providing the chassis-side vent hole 334C, the recess 334 can be prevented from becoming an obstacle during heat dissipation, and the heat generated in the DVD drive main body 200 can be effectively dissipated.
[0051] さらに、シャーシ 330の台座部 331を載置面上に載置可能に形成する。そして、外 装ケース 310における天板部 311の長尺方向一端側かつ背面側には、外装ケース 側通気孔 311 Aを設けている。また、シャーシ 330における台座部 331の長尺方向 一端側かつ背面側には、天板部 311の外装ケース側通気孔 311Aと略対向する位 置に、台座部側通気孔 331 Aを設けている。さらに、凹部 334の内周面には軸方向 が鉛直方向に略沿う状態でシャーシ側通気孔 334Cを形成している。このため、 DV Dドライブ本体 200で発生した熱が放熱空間 Hに伝播した際、台座部側通気孔 331 Aカゝら外気が導入され、 DVDドライブ本体 200で発生した熱は導入された外気と共 に放熱空間 Hにおける鉛直方向上側に移動し、外装ケース側通気孔 311 Aを通って 装置外部に放出することができる。この時、凹部 334のシャーシ側通気孔 334Cが熱 が移動し易 、鉛直方向に沿って形成されて!、るので、外気がシャーシ側通気孔 334 Cを通過して効果的に放熱することができる。 Furthermore, the pedestal 331 of the chassis 330 is formed so as to be placed on the placement surface. An exterior case side air hole 311 A is provided on one end side in the longitudinal direction and the back side of the top plate portion 311 in the exterior case 310. In addition, a pedestal portion side air hole 331A is provided at a position substantially opposite to the exterior case side air hole 311A of the top plate portion 311 on one end side and the back side of the pedestal portion 331 in the chassis 330. . Further, a chassis side air hole 334C is formed on the inner peripheral surface of the recess 334 so that the axial direction is substantially along the vertical direction. For this reason, when the heat generated in the DV D drive main body 200 propagates to the heat dissipation space H, outside air is introduced from the pedestal side vent 331 A, and the heat generated in the DVD drive main body 200 is separated from the introduced outside air. Both It can move to the upper side in the vertical direction in the heat radiation space H and can be discharged to the outside of the apparatus through the outer case side air hole 311 A. At this time, the chassis-side vent hole 334C of the recess 334 is formed along the vertical direction so that heat easily moves! Therefore, the outside air can pass through the chassis-side vent hole 334C and effectively radiate heat. it can.
[0052] そして、シャーシ 330を、鋼板のプレス加工により形成している。このため、シャーシ 330を製造するに当り、所定の形状に打ち抜き加工した鋼板の所定の部位に対して プレスカ卩ェすることにより、凹部 334、載置部 331B、保持部材取付部 331Cを容易 に突出形成することができる。したがって、高い製造効率でシャーシ 330を成形する ことができる。特に、シャーシ 330に用いる鋼板を薄肉の鋼板にすれば、プレス加工 による成形がさらに容易となり、かつ、完成した録画再生装置 100全体の軽量化を図 ることがでさる。 [0052] The chassis 330 is formed by pressing a steel plate. For this reason, when manufacturing the chassis 330, the concave portion 334, the mounting portion 331B, and the holding member attaching portion 331C can be easily projected by press-carrying a predetermined portion of the steel plate punched into a predetermined shape. Can be formed. Therefore, the chassis 330 can be molded with high manufacturing efficiency. In particular, if the steel plate used for the chassis 330 is a thin steel plate, it becomes easier to form by press working, and the weight of the completed recording / playback apparatus 100 can be reduced.
[0053] また、凹部 334を、第 1の折曲部 333の長尺方向と直交する方向の略中間部に互 いに平行する一対の切欠を形成し、これら切欠間を保持部材 340と対向する方向へ 所定寸法だけ押し出した状態に形成している。このため、鋼板のプレス加工により凹 部 334を形成するのに少ない押圧力で済むので、部材に与えるダメージを減らすこと ができ、かつ加工に要するエネルギー負荷も軽減することができる。また、形成する 切欠の長さを調整するか、あるいは、形成した切欠の間を押出す圧力を適宜調整す れば、凹部 334の突出する高さを任意に設定できる。  [0053] Further, the recess 334 is formed with a pair of notches parallel to the substantially middle portion in the direction orthogonal to the longitudinal direction of the first bent portion 333, and the gap between the notches faces the holding member 340. It is formed in a state where it has been pushed out by a predetermined dimension in the direction to go. For this reason, since a small pressing force is sufficient to form the concave portion 334 by pressing the steel plate, damage to the member can be reduced and the energy load required for the processing can be reduced. Further, the height at which the recess 334 protrudes can be arbitrarily set by adjusting the length of the notch to be formed or by appropriately adjusting the pressure for extruding between the formed notches.
[0054] さらに、凹部 334において、一対の連結部 334Bを、第 1の折曲部 333に対して斜 めに傾 、た状態で形成し、一対の連結部 334Bでシャーシ側当接面 334Aにおける 第 1の折曲部 333の長尺方向両端側と第 1の折曲部 333とを一連に連結している。こ れにより、シャーシ側通気孔 334Cの軸直交方向の断面形状が略台形状となってい る。このため、一対の連結部 334Bが第 1の折曲部 333に対して斜めに傾いた状態で シャーシ側当接面 334Aを支持して 、るので、シャーシ側当接面 334Aは第 1の折曲 部 333の長尺方向に対して大きな抗カを有すことができ、 DVDドライブ本体 200を 安定的に保持できる。また、鋼板のプレス加工においても、一対の連結部 334Bを第 1の折曲部 333に対して斜めに傾いた状態で形成するので、少ない押圧力で力卩ェで き、部材に与えるダメージおよび力卩ェに要するエネルギー負荷を軽減することができ る。 [0054] Further, in the recess 334, a pair of connecting portions 334B is formed in an inclined state with respect to the first bent portion 333, and the pair of connecting portions 334B is formed on the chassis-side contact surface 334A. Both ends in the longitudinal direction of the first bent part 333 and the first bent part 333 are connected in series. As a result, the cross-sectional shape of the chassis side air hole 334C in the direction perpendicular to the axis is substantially trapezoidal. For this reason, the chassis side contact surface 334A is supported by the first bent portion 333 while supporting the chassis side contact surface 334A in a state where the pair of connection portions 334B is inclined with respect to the first bent portion 333. It can have a large resistance against the longitudinal direction of the curved portion 333, and can stably hold the DVD drive main body 200. Also, in the press working of a steel plate, the pair of connecting portions 334B are formed in an obliquely inclined state with respect to the first bent portion 333. The energy load required for power can be reduced. The
[0055] また、凹部 334に、ケース体 210に当接されるシャーシ側当接面 334Aを設け、こ のシャーシ側当接面 334Aには当該シャーシ側当接面 334Aとケース体 210とを接 合するためのねじ 334A2が螺合されるねじ穴 334A1を穿設している。また、保持部 材 340に、ケース体 210に当接される保持部材側当接面部 341を設け、この保持部 材側当接面部 341には当該保持部材側当接面部 341とケース体とを接合するため のねじ 341Bが螺合されるねじ穴 341Aを穿設している。このため、ケース体 210をシ ヤーシ側当接面 334Aおよび保持部材側当接面部 341で強固に保持できる。また、 ねじ 334A2, 341 Bでシャーシ側当接面 334Aおよび保持部材側当接面部 341をそ れぞれ締め付ければ、組み付け作業を容易に行うことができる。そして、録画再生装 置 100を修理する際にも、ねじ 334A2, 341Bなどを外すだけで DVDドライブ本体 2 00を取り外すことができるので、製造時だけでなく修理時における良好な組み付け '性をち確保することができる。  In addition, a chassis-side contact surface 334A that contacts the case body 210 is provided in the recess 334, and the chassis-side contact surface 334A and the case body 210 are in contact with the chassis-side contact surface 334A. A screw hole 334A1 into which a screw 334A2 for mating is screwed is formed. Further, the holding member member 340 is provided with a holding member side contact surface portion 341 that contacts the case body 210, and the holding member member side contact surface portion 341 includes the holding member side contact surface portion 341 and the case body. A screw hole 341A into which a screw 341B for joining is screwed is formed. Therefore, the case body 210 can be firmly held by the chassis side contact surface 334A and the holding member side contact surface portion 341. Further, if the chassis-side contact surface 334A and the holding member-side contact surface portion 341 are respectively tightened with the screws 334A2 and 341B, the assembly work can be easily performed. When repairing the recording / playback device 100, the DVD drive body 200 can be removed simply by removing the screws 334A2, 341B, etc. Can be secured.
[0056] そして、シャーシ側当接面 334Aおよび保持部材側当接面部 341を DVDドライブ 本体 200におけるケース体 210に当接している。また、シャーシ側当接面 334Aのね じ穴 334A1周縁に形成されたバリと、保持部材側当接面部 341のねじ穴 341A周縁 に形成されたバリとを、ねじ 334A2, 341Bがケース体 210の一方の側面 211に螺合 することによりケース体 210の両側面 211, 212に食い込む状態としている。これによ り、 DVD処理装置より発生した高周波電流は、シャーシ側当接面 334Aおよび保持 部材側当接面部 341に確実に伝達し、これら部材を介してアースされるので、高周 波電流により制御装置における各部が損傷することを防ぐことができる。したがって、 ねじ 334A2, 341Bを穿設した際に付加的に形成されたバリを、研磨するなどして除 去することなくそのまま活用することで、高周波電流による障害を確実に防ぐことがで きる。  Then, the chassis side contact surface 334 A and the holding member side contact surface portion 341 are in contact with the case body 210 in the DVD drive main body 200. Further, the burr formed on the periphery of the screw hole 334A1 of the chassis side abutting surface 334A and the burr formed on the periphery of the screw hole 341A of the holding member side abutting surface portion 341 are connected to the case body 210 by screws 334A2 and 341B. By screwing into one side surface 211, it is in a state of biting into both side surfaces 211, 212 of the case body 210. As a result, the high-frequency current generated from the DVD processing apparatus is reliably transmitted to the chassis-side contact surface 334A and the holding member-side contact surface portion 341, and is grounded through these members. It is possible to prevent each part in the control device from being damaged. Therefore, by using the burr additionally formed when the screws 334A2 and 341B are drilled without being removed by polishing or the like, it is possible to reliably prevent a failure due to a high-frequency current.
[0057] また、第 1の折曲部 333の長尺方向と直交する方向の略中間部における前面側に 、その長尺方向に沿って複数の凹部 334を設けている。このため、ケース体 210を複 数の凹部 334で保持するので、 DVDドライブ本体 200をシャーシ 330に確実に固定 することができる。したがって、 DVDドライブ本体 200の安定した録画処理および再 生処理を確保することができる。 [0057] In addition, a plurality of recesses 334 are provided along the longitudinal direction on the front surface side in a substantially intermediate portion of the first bent portion 333 in a direction orthogonal to the longitudinal direction. Therefore, the case body 210 is held by the plurality of recesses 334, so that the DVD drive main body 200 can be securely fixed to the chassis 330. Therefore, stable recording processing and Raw processing can be secured.
[0058] さらに、シャーシ 330を製造するに当り、所定の形状に打ち抜き加工した鋼板をプ レス加工して、凹部 334を突出形成している。そして、凹部 334の突出方向と同一方 向にねじ穴 334A1を穿孔形成している。このため、ねじ穴 334A1の周縁には保持 部材 340と対向する方向に向けてバリが突出して形成されるが、このバリの突出方向 とねじ 334A2を螺合する方向とが同一方向であるので、バリを削除する処理をしなく てもノ リがねじ 334A2の取付作業において支障とならない。むしろ、バリを除去せず に残したままケース体 210の一方の側面 211に螺合することでケース体 210とシヤー シ 330との確実な導通が図れ、 DVDドライブ本体 200で発生した高周波電流による 障害を確実に防ぐことができる。  Furthermore, when manufacturing the chassis 330, the steel plate punched into a predetermined shape is pressed to form the recess 334 in a protruding manner. A screw hole 334A1 is formed in the same direction as the protruding direction of the recess 334. For this reason, a burr protrudes from the periphery of the screw hole 334A1 in a direction facing the holding member 340, and the protruding direction of this burr and the direction in which the screw 334A2 is screwed are the same direction. Even if you do not remove the burr, the screw will not interfere with the installation of the screw 334A2. Rather, the case body 210 and the chassis 330 can be securely connected by being screwed into one side surface 211 of the case body 210 without removing the burrs, and the high frequency current generated in the DVD drive body 200 can be achieved. A failure can be prevented reliably.
[0059] そして、第 1の側面部 312の長尺方向他端側には、第 2の側面部 313に対向する 方向に陥没形成された複数のねじ頭収容部 312Aを設けている。このため、第 1の折 曲部 333と第 1の側面部 312との間には間隙 Kが形成されるので、 DVDドライブ本 体 200で発生した熱が外装ケース 310における第 1の側面部 312に直接伝わること を防ぐことができる。したがって、録画再生装置 100に隣接する外部機器などに熱に よる影響を与えることがなぐまた、利用者は外装ケース 310の第 1の側面部 312を安 全に虫ることができる。  [0059] A plurality of screw head accommodating portions 312A are provided on the other end in the longitudinal direction of the first side surface portion 312 so as to be recessed in a direction facing the second side surface portion 313. For this reason, a gap K is formed between the first bent portion 333 and the first side surface portion 312, so that the heat generated in the DVD drive main body 200 is generated by the first side surface portion 312 in the outer case 310. Can be prevented from being transmitted directly to. Therefore, the external device adjacent to the recording / playback apparatus 100 is not affected by heat, and the user can safely insect the first side surface 312 of the outer case 310.
[0060] 〔実施の形態の変形〕  [Modification of Embodiment]
なお、本発明は上述した実施の形態に限定されるものではなぐ本発明の目的を達 成できる範囲で以下に示される変形をも含むものである。  It should be noted that the present invention is not limited to the above-described embodiments, but includes modifications shown below as long as the object of the present invention can be achieved.
[0061] 前記実施の形態では、電気機器としては、 DVDドライブ本体 200を収容する録画 再生装置 100を例示して説明した力 上述したように、 DVDドライブ本体 200として はディスクトレイ 220を有した構成に限らず、 、わゆるスロットインタイプのディスクドラ イブやスリムドライブなどのディスクドライブをも対象とすることができる。また、被収容 部材としては、 DVDドライブ本体 200を例示した力 ハードディスクドライブなどの他 の記録媒体や着脱されな!ヽ記録媒体を処理する!ヽずれのディスクドライブ、外周面 に記録面が設けられた円筒状の記録媒体や磁気テープなどのディスク状ではな 、 ずれの記録媒体を処理するドライブ、さらには、通信回路や演算装置など、電力の供 給により動作するいずれの機器本体をも対象とすることができる。 In the above-described embodiment, as the electric device, the power described by exemplifying the recording / reproducing apparatus 100 that accommodates the DVD drive main body 200. As described above, the DVD drive main body 200 includes the disc tray 220. However, the present invention can also be applied to disk drives such as so-called slot-in type disk drives and slim drives. In addition, as a member to be accommodated, there is another recording medium such as a hard disk drive, which is an example of the DVD drive main body 200, or a recording medium that is not attached / detached, a misaligned disk drive, and a recording surface provided on the outer peripheral surface. In addition, it is not in the form of a disk such as a cylindrical recording medium or a magnetic tape, but a drive for processing a misaligned recording medium, a communication circuit, an arithmetic unit, etc. Any device body that operates by feeding can be targeted.
[0062] 前記実施の形態では、シャーシ 330の第 1の折曲部 333を、所定形状に打ち抜い た鋼板をプレス加工して折曲形成することにより設ける構成を例示したが、これに限 らない。すなわち、シャーシ 330の第 1の折曲部 333は、例えばアルミ（aluminum)板 のプレス加工や、合成樹脂による射出形成加工などにより形成する構成としても構わ ない。また、台座部 331とは別体の部材を台座部 331の長尺方向一端側に取り付け て、これをシャーシ側面とする構成としても構わない。これらのような構成でも、前記 実施の形態と同様に、 DVDドライブ本体 200を筐体内部に容易に組み付けることが できる。  In the above embodiment, the configuration in which the first bent portion 333 of the chassis 330 is provided by pressing a steel plate punched into a predetermined shape to be bent is exemplified, but the present invention is not limited thereto. . That is, the first bent portion 333 of the chassis 330 may be formed by, for example, pressing an aluminum plate, injection molding with a synthetic resin, or the like. Further, a member separate from the pedestal portion 331 may be attached to one end side in the longitudinal direction of the pedestal portion 331, and this may be configured as a chassis side surface. Even in such a configuration, the DVD drive main body 200 can be easily assembled in the housing as in the above-described embodiment.
[0063] 前記実施の形態では、凹部 334を、第 1の折曲部 333の長尺方向と直交する方向 の略中間部に互いに平行する一対の切欠を形成し、これら切欠の間を保持部材 34 0と対向する方向に所定寸法だけ押し出した状態に形成する構成としたが、これに限 らない。すなわち、突出部は、例えば、第 1の折曲部 333に別体構造のブロック体を 取り付ける構成や、第 1の折曲部 333にコ字型の切欠を形成し、舌片状に突出形成 する構成としてもよい。このような構成でも、放熱空間 Hと同様の機能を有した空間を 形成することができる。  [0063] In the embodiment, the recess 334 is formed with a pair of notches parallel to each other at a substantially middle portion in the direction perpendicular to the longitudinal direction of the first bent portion 333, and the holding member is interposed between these notches However, the present invention is not limited to this. That is, for example, the protruding portion is configured such that a block body having a separate structure is attached to the first bent portion 333, or a U-shaped notch is formed in the first bent portion 333 so as to protrude in a tongue shape. It is good also as composition to do. Even with such a configuration, a space having the same function as the heat radiation space H can be formed.
[0064] 前記実施の形態では、凹部 334は、保持部材 340と対向する方向へ突出して形成 されるとした力 これに限らない。すなわち、例えば、図 5に示す録画再生装置 100A のような構成としてもよい。この図 5に示す録画再生装置 100Aは図 1ないし図 4に示 す録画再生装置 100の第 1の折曲部 333においてのみ構成が異なる。  [0064] In the above embodiment, the recess 334 is not limited to the force formed so as to protrude in the direction facing the holding member 340. That is, for example, a configuration such as a recording / reproducing apparatus 100A shown in FIG. The recording / reproducing apparatus 100A shown in FIG. 5 is different only in the first bent portion 333 of the recording / reproducing apparatus 100 shown in FIGS.
[0065] 図 5において、録画再生装置 100Aは、筐体 300Aにおけるシャーシ 330Aに第 1 の折曲部 336を備えている。この第 1の折曲部 336には、複数のねじ穴 336Aが形成 され、このねじ穴 336Aを介して複数のねじ 336Bがケース体 210の一方の側面 211 に螺合されることによりケース体 210が第 1の折曲部 336に取り付けられる。また、第 1の折曲部 336には、第 1の折曲部 336の一部が保持部材 340と対向する方向の反 対方向に突出形成した突出部 337が複数設けられている。この突出部 337は、平面 部 337Aと、一対の連結部 337Bと、シャーシ側通気孔 337Cとを備えている。平面部 337Aは、ねじ 312Bが螺合されるねじ穴 337A1を有し、外装ケース 310の第 1の側 面部 312が取り付けられる。なお、突出部 337は、ねじ穴 337A1に螺合されたねじ 3 12Bの先端が保持部材 340と対向する方向へ突出する寸法よりも大きな高さ寸法を 有している。そして、一対の連結部 337Bは、第 1の折曲部 336に対して斜めに傾い た状態で形成され、平面部 337Aにおける第 1の折曲部 336の長尺方向両端側と第 1の折曲部 336とを一連に連結する。シャーシ側通気孔 334Cは、平面部 337Aと一 対の連結部 337Bとで囲まれた軸直交方向の断面が略台形状の空間であり、その軸 方向が鉛直方向に略平行する状態、すなわち、第 1の折曲部 336の長尺方向に略 直交する状態で貫通形成されている。これにより、外装ケース 310の第 1の側面部 31 2とシャーシ 330の第 1の折曲部 336との間に放熱空間 HIが形成される。 In FIG. 5, a recording / reproducing apparatus 100A includes a first bent portion 336 in a chassis 330A in a housing 300A. A plurality of screw holes 336A are formed in the first bent portion 336, and the plurality of screws 336B are screwed to one side surface 211 of the case body 210 through the screw holes 336A, thereby the case body 210. Is attached to the first bent portion 336. The first bent portion 336 is provided with a plurality of protruding portions 337 in which a part of the first bent portion 336 is formed to protrude in a direction opposite to the direction facing the holding member 340. The projecting portion 337 includes a flat portion 337A, a pair of connecting portions 337B, and a chassis side air hole 337C. The flat surface portion 337A has a screw hole 337A1 into which the screw 312B is screwed. Face part 312 is attached. Note that the protruding portion 337 has a height dimension that is larger than the dimension in which the tip of the screw 312B screwed into the screw hole 337A1 protrudes in a direction facing the holding member 340. The pair of connecting portions 337B is formed in an inclined state with respect to the first bent portion 336, and the both ends of the first bent portion 336 in the plane portion 337A in the longitudinal direction and the first bent portion. The music part 336 is connected in series. The chassis side air hole 334C is a space having a substantially trapezoidal cross section in the direction perpendicular to the axis surrounded by the flat surface portion 337A and the pair of connecting portions 337B, that is, a state in which the axial direction is substantially parallel to the vertical direction, The first bent part 336 is formed so as to penetrate in a state substantially orthogonal to the longitudinal direction. As a result, a heat radiation space HI is formed between the first side surface portion 312 of the outer case 310 and the first bent portion 336 of the chassis 330.
[0066] このような構成の場合、図 1ないし図 4に示した録画再生装置 100と同様に、 DVD ドライブ本体 200を筐体 300Aに組み付ける際、第 1の折曲部 336および保持部材 3 40で DVDドライブ本体 200のケース体 210を挟み、 DVDドライブ本体 200を筐体 3 00に固定することができる。これにより、シャーシ 330の側面である第 1の折曲部 336 を利用することで、 DVDドライブ本体 200を筐体 300Aに固定するための部材が保 持部材 340のみで済むので、従来よりも部品点数および組み付け工数を大幅に削 減することができる。したがって、筐体 300A内部に DVDドライブ本体 200を容易に 組み付けることができ、製造効率の向上に寄与することができる。  In the case of such a configuration, when the DVD drive main body 200 is assembled to the housing 300A, similarly to the recording / reproducing apparatus 100 shown in FIGS. 1 to 4, the first bent portion 336 and the holding member 3 40 The DVD drive body 200 can be fixed to the housing 300 by sandwiching the case body 210 of the DVD drive body 200. By using the first bent portion 336 on the side surface of the chassis 330, the member for fixing the DVD drive main body 200 to the housing 300A is only the holding member 340. The number of points and assembly man-hours can be greatly reduced. Therefore, the DVD drive main body 200 can be easily assembled in the housing 300A, which can contribute to an improvement in manufacturing efficiency.
[0067] また、突出部 337を設けたことにより、外装ケース 310が平面部 337Aにねじ 312B にて取り付けられた際に、平面部 337A力も保持部材 340に対向する方向に突出し たねじ 312Bの先端がシャーシ側通気孔 337C内で納まり、ケース体 210の一方の側 面 211に突き当たることがない。したがって、 DVDドライブ本体 200を筐体 300Aに 固定するためにシャーシ 330Aの第 1の折曲部 336を利用することが可能となり、力 つ、外装ケース 310をシャーシ 330Aに取り付ける際にねじ 312Bの先端がケース体 210の側面 211に突き当たってしまう不具合も同時に解決することができる。さらに、 DVDドライブ本体 200で発生した熱を放熱空間 HIに発散することができる。また、 ケース体 210の一方の側面 211がシャーシ 330Aの第 1の折曲部 336と広い面積で 密着した状態となって 、るので、 DVDドライブ本体 200で発生した熱をシャーシ 330 Aに効率良く伝達することができ、良好に放熱することができる。これと共に、ケース 体 210の一方の側面 211がシャーシ 330Aの第 1の折曲部 336と広い面積で密着す ることにより、 DVDドライブ本体 200で発生した電磁波が第 1の折曲部 336にて吸収 され、当該電磁波が装置外部に漏洩することを確実に防ぐことができる。 [0067] Further, by providing the projecting portion 337, when the outer case 310 is attached to the flat surface portion 337A with the screw 312B, the force of the flat surface portion 337A also protrudes in the direction facing the holding member 340. Is housed in the chassis side air vent 337C and does not hit one side surface 211 of the case body 210. Therefore, the first bent portion 336 of the chassis 330A can be used to fix the DVD drive main body 200 to the housing 300A. When the outer case 310 is attached to the chassis 330A, the tip of the screw 312B can be used. The problem that the battery hits the side surface 211 of the case body 210 can be solved at the same time. Furthermore, the heat generated in the DVD drive body 200 can be dissipated into the heat dissipation space HI. In addition, since one side surface 211 of the case body 210 is in close contact with the first bent portion 336 of the chassis 330A in a wide area, the heat generated in the DVD drive main body 200 is efficiently applied to the chassis 330A. It can be transmitted and can be radiated well. Along with this, the case When one side surface 211 of the body 210 is in close contact with the first bent part 336 of the chassis 330A over a wide area, the electromagnetic wave generated in the DVD drive main body 200 is absorbed by the first bent part 336, Electromagnetic waves can be reliably prevented from leaking outside the apparatus.
[0068] 前記実施の形態では、凹部 334とケース体 210とをねじ 334A2で接合し、保持部 材 340とケース体 210とをねじ 341Bで接合し、外装ケース 310とシャーシ 330の第 1 の折曲部 333とをねじ 312Bで接合する構成とした力これに限らない。すなわち、これ ら部材同士を接合する構成としてはいずれでもよぐ例えば、導電性の接着材で接着 する構成ゃ部材同士が互いに係止し合う係止片を設ける構成などとしても構わない。  [0068] In the embodiment, the recess 334 and the case body 210 are joined by the screw 334A2, the holding member 340 and the case body 210 are joined by the screw 341B, and the outer case 310 and the chassis 330 are first folded. This is not limited to the force with which the curved portion 333 is joined with the screw 312B. That is, any configuration may be used for joining these members. For example, a configuration in which the members are bonded with a conductive adhesive or a configuration in which a locking piece for locking the members together is provided.
[0069] 前記実施の形態では、録画再生装置 100は、シャーシ 330の台座部 331を載置面 に載置するいわゆる横置き型を例示した力 外装ケース 310の第 1の側面部 312を 載置面に載置するような 、わゆる縦置き型としてもょ 、。このような構成にぉ 、ても、 図 1ないし図 4に示した録画再生装置 100と略同様の作用効果を奏することができ、 かつ、載置面が狭小であっても好適に載置することができる。  In the embodiment described above, the recording / playback apparatus 100 mounts the first side surface portion 312 of the outer case 310 exemplifying a so-called horizontal type in which the pedestal portion 331 of the chassis 330 is mounted on the mounting surface. As a vertical type that can be placed on a surface. Even with such a configuration, it is possible to achieve substantially the same operation and effect as the recording / playback apparatus 100 shown in FIGS. 1 to 4, and it is suitably placed even if the placement surface is narrow. be able to.

That is, for example, the screw hole 312A1 of the outer case 310, the screw hole 211A of the case body 210, and the screw hole 333A in the first bent portion 333 of the chassis 330 are provided in a state of facing each other, and one screw The exterior case 310, the case body 210, and the chassis 330 may be joined together. In such a configuration, the step of providing the recess 334 and the step of joining the case body 210 and the recess 334 with the screw 334A2 can be omitted, so that the manufacturing efficiency can be improved. Further, for example, the length of the screw portion of the screw 312B may be appropriately adjusted so that the first bent portion 333 and the first side surface portion 312 of the outer case 310 are within the thickness range. Even in such a configuration, since the step of forming the recess 334 can be omitted, the manufacturing efficiency can be improved.
[0071] 前記実施の形態では、外装ケース側通気孔 311Aおよび台座部側通気孔 331A は、図 4に示したように直線状に切り欠いて形成する構成とした力 これに限らない。 すなわち、これらの通気孔は外気の出入りが可能な状態に開口形成されていればい ずれの形状およびいずれの配置でもよぐ例えば、外装ケース 310およびシャーシ 3 30〖こは、 DVDドライブ本体 200で発生した電磁波の周波数に対応させて直径寸法 を適宜調整した複数の円状孔を規則的に配設する構成としてもよい。このような構成 の場合、放熱効果に加えて装置外部へ漏洩する電磁波を良好に遮蔽する効果を奏 することができる。また、外装ケース 310およびシャーシ 330には、外装ケース側通気 孔 311 Aおよび台座部側通気孔 331 Aを設けない構成としてもよい。このような構成 の場合、これら通気孔を形成する工程を省略することができるので、製造効率を向上 することができる。 [0071] In the above embodiment, the exterior case side air hole 311A and the pedestal side air hole 331A are not limited to this force, as shown in FIG. In other words, these vents can be used in any shape and any arrangement as long as they are open to allow outside air to enter and exit. For example, the outer case 310 and the chassis 330 are generated in the DVD drive main body 200. Diameter corresponding to the frequency of the electromagnetic wave It is good also as a structure which regularly arrange | positions the several circular hole which adjusted these suitably. In such a configuration, in addition to the heat dissipation effect, it is possible to effectively shield electromagnetic waves leaking outside the apparatus. Further, the exterior case 310 and the chassis 330 may be configured such that the exterior case side air hole 311 A and the base part side air hole 331 A are not provided. In the case of such a configuration, the process of forming these air holes can be omitted, so that the production efficiency can be improved.
[0072] 前記実施の形態では、ケース体 210、外装ケース 310、シャーシ 330および保持部 材 340を鋼板のプレスカ卩ェにて形成する構成を例示した力 これに限らず、例えば アルミ板のプレス加工や合成樹脂による射出形成加工などにより形成する構成として も構わない。  [0072] In the above-described embodiment, the force exemplifying the configuration in which the case body 210, the exterior case 310, the chassis 330, and the holding member 340 are formed by a steel sheet press carriage. Alternatively, it may be formed by an injection molding process using synthetic resin.
