Description

本発明は、トレイの固定機構に関し、特に振動源が搭載されるトレイの被固定部材への固定機構に関する。 The present invention relates to a tray fixing mechanism, and more particularly to a mechanism for fixing a tray on which a vibration source is mounted to a fixed member.

振動源の一種であるＨＤＤ（Hard Disk Drive）等の記憶装置を、被固定部材の一種であるケージに収めるために利用するトレイには、ゲージへの取付け、又は取外し(挿抜)の容易性と記憶装置の自己振動を抑えるための防振性能が求められる。 The tray used to store a storage device such as HDD (Hard Disk Drive), which is a type of vibration source, in a cage, which is a type of fixed member, is easy to attach to or remove from the gauge. Anti-vibration performance is required to suppress the self-vibration of the storage device.

そのため、トレイが工具やネジを利用せずに容易にケージから挿抜できるように、設計上、トレイとケージの間にはクリアランスを設けることが一般的である。しかし、クリアランスの影響でトレイをケージにしっかりと固定することができず、記憶装置の自己振動を抑えることができなかった。また、記憶装置の自己振動を抑える方法としては、トレイをケージにネジ固定することが有用であるが、この場合、挿抜の容易性が失われてしまうという課題があった。 Therefore, it is common in design to provide a clearance between the tray and the cage so that the tray can be easily inserted and removed from the cage without using tools or screws. However, the tray cannot be firmly fixed to the cage due to the influence of the clearance, and the self-vibration of the storage device cannot be suppressed. Further, as a method for suppressing the self-vibration of the storage device, it is useful to screw the tray to the cage, but in this case, there is a problem that the ease of insertion / extraction is lost.

ところで、特許文献１には、側部から内方に向かって突出する保持部が形成された筐体と、記憶装置が搭載され、側部から外方に向かって突出する防振部が形成されたトレイと、を備えるディスク回転装置が開示されている。保持部は、平面から見て筺体の開口側に向かって幅寸法が狭くなる三角形状に形成されており、筺体の側部における開口側の端部に配置されている。また、防振部は、半円形状に形成されており、トレイを筺体に挿入したとき、保持部に接触する位置に配置されている。トレイを筺体に挿入し、防振部を保持部の傾斜面に食い込ませることで、トレイを筺体に固定している。 By the way, in Patent Document 1, a housing in which a holding part that protrudes inward from the side part and a storage device are mounted, and a vibration isolating part that protrudes outward from the side part is formed. And a disk rotating device including a tray. The holding part is formed in a triangular shape whose width dimension becomes narrower toward the opening side of the housing as viewed from above, and is arranged at the end of the opening side of the side of the housing. Further, the vibration isolating portion is formed in a semicircular shape, and is disposed at a position where it comes into contact with the holding portion when the tray is inserted into the housing. The tray is fixed to the casing by inserting the tray into the casing and causing the vibration isolator to bite into the inclined surface of the holding section.

なお、特許文献２には、車体ドアの外周に沿って配設したワイヤーに張力を付加することで、ワイヤー受部を締め付け、車体ドアの閉まり剛性を高める技術が開示されている。
また、特許文献３には、モータの回転駆動力を、無端体を介してレンズ枠に伝達する構成において、前記無端体の張力の調整を、プーリを介して行う技術が開示されている。 Patent Document 2 discloses a technique in which a wire receiving portion is tightened to increase the closing rigidity of the vehicle body door by applying tension to the wire disposed along the outer periphery of the vehicle body door.
Patent Document 3 discloses a technique for adjusting the tension of the endless body via a pulley in a configuration in which the rotational driving force of the motor is transmitted to the lens frame via the endless body.

特許文献１の技術は、防振部を保持部の傾斜面に食い込ませただけでは、トレイと筺体との固定が十分でなく、当該トレイに搭載された記憶装置が自己振動を生じる可能性がある。 In the technique of Patent Document 1, the tray and the housing are not sufficiently fixed only by causing the vibration isolating portion to bite into the inclined surface of the holding portion, and the storage device mounted on the tray may cause self-vibration. is there.

本発明の実施の形態に係るトレイの固定機構について説明する。但し、本発明が以下の実施の形態に限定される訳ではない。また、説明を明確にするため、以下の記載及び図面は、適宜、簡略化されている。なお、以下の説明における上下前後左右方向は、図２に示す上下前後左右方向を基準に説明している。 A tray fixing mechanism according to an embodiment of the present invention will be described. However, the present invention is not limited to the following embodiment. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate. In the following description, the up, down, front, back, left, and right directions are described based on the up, down, front, back, left, and right directions shown in FIG.

本実施の形態のトレイの固定機構（以下、単に固定機構という場合がある。）１は、図１乃至図３に示すように、被固定部材の一種であるゲージ２に対して、振動源の一種であるＨＤＤ等の記憶装置３が搭載されるトレイ４を挿抜する際に好適に用いられる。この固定機構１は、張力付加機構５によって、トレイ４の外周に沿って配設されたワイヤー６に張力を付加して、トレイ４の側部４１に形成された第１収納部４１ｃから固定部材７を引き出し、当該固定部材７をゲージ２の側部２１に接触させることで、トレイ４をゲージ２に固定する構成である。 As shown in FIGS. 1 to 3, the tray fixing mechanism (hereinafter sometimes simply referred to as a fixing mechanism) 1 according to the present embodiment has a vibration source for a gauge 2, which is a type of fixed member. This is suitably used when a tray 4 on which a storage device 3 such as an HDD is mounted is inserted and removed. The fixing mechanism 1 applies a tension to the wire 6 disposed along the outer periphery of the tray 4 by the tension applying mechanism 5, and fixes the fixing member from the first storage portion 41 c formed on the side portion 41 of the tray 4. The tray 4 is fixed to the gauge 2 by pulling out 7 and bringing the fixing member 7 into contact with the side portion 21 of the gauge 2.

具体的に云うと、固定機構１は、図２及び図３に示すように、トレイ４、張力付加機構５、ワイヤー６、固定部材７を備える。トレイ４は、図４に示すように、側部４１、底部４２、前部４３を備える。側部４１は、底部４２の左右の側縁に沿って設けられている。側部４１は、上述したように固定部材７をゲージ２の側部２１に接触させた際に変形しないように、底部４２に接合され、さらに自身の強度を有する。側部４１は、例えば樹脂成形品である。 Specifically, the fixing mechanism 1 includes a tray 4, a tension applying mechanism 5, a wire 6, and a fixing member 7, as shown in FIGS. As shown in FIG. 4, the tray 4 includes a side portion 41, a bottom portion 42, and a front portion 43. The side portion 41 is provided along the left and right side edges of the bottom portion 42. The side portion 41 is joined to the bottom portion 42 and has its own strength so as not to be deformed when the fixing member 7 is brought into contact with the side portion 21 of the gauge 2 as described above. The side part 41 is, for example, a resin molded product.

側部４１には、図５に示すように、本体部４１ａ、接合部４１ｂを備える。本体部４１ａは、長尺の板状部材である。本体部４１ａには、長手方向に間隔を開けて、固定部材７が収納される第１収納部４１ｃが形成されている。本実施の形態の第１収納部４１ｃは、本体部４１ａを貫通するように形成されており、略矩形状に形成されている。さらに本体部４１ａの内側面（但し、外側面でも良い。）には、長手方向に沿って、ワイヤー６が収納される第２収納部４１ｄが形成されている。 As shown in FIG. 5, the side portion 41 includes a main body portion 41a and a joint portion 41b. The main body 41a is a long plate-like member. The main body portion 41a is formed with a first storage portion 41c in which the fixing member 7 is stored at an interval in the longitudinal direction. The 1st accommodating part 41c of this Embodiment is formed so that the main-body part 41a may be penetrated, and is formed in the substantially rectangular shape. Furthermore, the 2nd accommodating part 41d in which the wire 6 is accommodated along the longitudinal direction is formed in the inner surface (however, an outer surface may be sufficient) of the main-body part 41a.

詳細には、第２収納部４１ｄは、間隔を開けて配置された第１収納部４１ｃの間に形成される第１部分４１ｄ１、前側の第１収納部４１ｃから本体部４１ａの前端縁まで連続して延在する第２部分４１ｄ２、後側の第１収納部４１ｃから本体部４１ａの後端縁に到達する途中位置まで連続して延在する第３部分４１ｄ３を備える。 Specifically, the second storage part 41d is continuous from the first part 41d1 formed between the first storage parts 41c arranged at intervals, from the first storage part 41c on the front side to the front edge of the main body part 41a. And a third portion 41d3 that continuously extends from the first storage portion 41c on the rear side to a midway position that reaches the rear edge of the main body portion 41a.

本体部４１ａの前端部には、前部４３への接合部４１ｂが形成されている。接合部４１ｂは、トレイ４の内方に向かって突出する板状部材である。接合部４１ｂには、例えば側部４１を前部４３に接合するためのボルトを通すボルト孔４１ｅが形成されている。このボルト孔４１ｅにボルト（図示を省略）を通して、図６に示すように側部４１と前部４３とが接合されている。 A joint portion 41b to the front portion 43 is formed at the front end portion of the main body portion 41a. The joint portion 41 b is a plate-like member that protrudes inward of the tray 4. For example, a bolt hole 41e through which a bolt for joining the side portion 41 to the front portion 43 is passed is formed in the joint portion 41b. As shown in FIG. 6, the side portion 41 and the front portion 43 are joined through a bolt (not shown) through the bolt hole 41e.

ここで、接合部４１ｂは、図５に示すように、補強部４１ｆによって本体部４１ａに連結されていることが好ましい。補強部４１ｆは、例えば平面から見て三角形状の板状部材である。補強部４１ｆは、接合部４１ｂの上下に配置されている。補強部４１ｆの角を挟んで一方の辺が本体部４１ａに接合され、他方の辺が接合部４１ｂに接合されている。これにより、側部４１と前部４３との接合部の強度を上げることができる。 Here, as shown in FIG. 5, it is preferable that the joining part 41b is connected with the main-body part 41a by the reinforcement part 41f. The reinforcing portion 41f is, for example, a triangular plate-like member when viewed from the plane. The reinforcing part 41f is disposed above and below the joint part 41b. One side is joined to the main body part 41a across the corner of the reinforcing part 41f, and the other side is joined to the joint part 41b. Thereby, the intensity | strength of the junction part of the side part 41 and the front part 43 can be raised.

底部４２は、記憶装置３を搭載するのに十分な広さを有する。この底部４２の左右方向の幅寸法は、トレイ４を図１に示すように左右に間隔を開けて配置されたゲージ２の側部２１間に良好に挿入することができるように、当該側部２１間より若干短く設定されている。底部４２は、例えば金属製、樹脂成形品等である。ちなみに、本実施の形態の底部４２は、図４に示すように、軽量化のためにパンチング処理が施されている。この底部４２の左右両端縁に側部４１が接合され、さらに前端縁に前部４３が接合されている。 The bottom part 42 is wide enough to mount the storage device 3. The width dimension of the bottom portion 42 in the left-right direction is such that the tray 4 can be inserted well between the side portions 21 of the gauge 2 that are spaced apart from each other as shown in FIG. It is set slightly shorter than 21 intervals. The bottom portion 42 is made of, for example, a metal or a resin molded product. Incidentally, as shown in FIG. 4, the bottom portion 42 of the present embodiment is subjected to a punching process for weight reduction. The side part 41 is joined to the left and right end edges of the bottom part 42, and the front part 43 is joined to the front end edge.

前部４３は、カバー部材４３ａ、レバー部材４３ｂを備える。カバー部材４３ａは、図２等に示すように、トレイ４の前部として機能する。本実施の形態のカバー部材４３ａは、前側及び右側（但し、左側でも良い）が開口している略箱型部材である。カバー部材４３ａの内部には、図７に示すように、ワイヤー６が通される通路４３ｃが形成されている。カバー部材４３ａの左右側部にワイヤー６を内部に導き込む、又は導き出すための、切り欠き部４３ｄが形成されている。そして、カバー部材４３ａにおける左右方向の略中央位置に、ワイヤー６を支持する支持部４３ｅが形成されている。 The front portion 43 includes a cover member 43a and a lever member 43b. The cover member 43a functions as a front portion of the tray 4 as shown in FIG. The cover member 43a of the present embodiment is a substantially box-shaped member that is open on the front side and the right side (however, the left side may also be used). As shown in FIG. 7, a passage 43c through which the wire 6 is passed is formed inside the cover member 43a. Cutout portions 43d are formed in the left and right side portions of the cover member 43a to guide or lead the wires 6 into the interior. And the support part 43e which supports the wire 6 is formed in the approximate center position of the left-right direction in the cover member 43a.

さらにカバー部材４３ａの前側の開口部分を開閉するように、カバー部材４３ａにレバー部材４３ｂが回転可能に連結されている。詳細には、カバー部材４３ａの上下部は、レバー部材４３ｂの右側部に通された回転軸４３ｆを支持している。回転軸４３ｆは、カバー部材４３ａの前方右側部に配置されている。つまり、カバー部材４３ａの右側の開口部分は、レバー部材４３ｂが回転する際に、カバー部材４３ａに干渉しないために形成されている。 Further, a lever member 43b is rotatably connected to the cover member 43a so as to open and close the opening portion on the front side of the cover member 43a. Specifically, the upper and lower portions of the cover member 43a support a rotating shaft 43f that is passed through the right side portion of the lever member 43b. The rotating shaft 43f is disposed on the front right side of the cover member 43a. That is, the opening portion on the right side of the cover member 43a is formed so as not to interfere with the cover member 43a when the lever member 43b rotates.

レバー部材４３ｂは、張力付加機構５として機能する。レバー部材４３ｂは、本体部４３ｇ、突出部４３ｈを備える。レバー部材４３ｂは、例えば樹脂成形品である。本体部４３ｇは、図６及び図７に示すように、長尺の棒状部材である。本体部４３ｇの右側部には、上下方向の回転軸４３ｆが通されている。ちなみに、本実施の形態の本体部４３ｇの右側部には、トレイ４の内方に突出するアーム部４３ｉが形成されており、アーム部４３ｉの先端部に回転軸４３ｆが通されている。これにより、図８及び図９に示すように、レバー部材４３ｂを閉じた状態とした際に、アーム部４３ｉの長さ分だけ、回転軸４３ｆより前方にレバー部材４３ｂが配置され、カバー部材４３ａの支持部４３ｅとの干渉を防ぐことができる。本体部４３ｇの左側部には、突出部４３ｈが形成されている。 The lever member 43 b functions as the tension applying mechanism 5. The lever member 43b includes a main body 43g and a protrusion 43h. The lever member 43b is, for example, a resin molded product. As shown in FIGS. 6 and 7, the main body 43g is a long rod-shaped member. A rotating shaft 43f in the vertical direction is passed through the right side of the main body 43g. Incidentally, an arm portion 43i protruding inward of the tray 4 is formed on the right side portion of the main body portion 43g of the present embodiment, and a rotating shaft 43f is passed through a tip portion of the arm portion 43i. As a result, as shown in FIGS. 8 and 9, when the lever member 43b is closed, the lever member 43b is disposed in front of the rotation shaft 43f by the length of the arm portion 43i, and the cover member 43a. Interference with the support portion 43e can be prevented. A protrusion 43h is formed on the left side of the main body 43g.

突出部４３ｈは、トレイ４の内方に突出する。突出部４３ｈは、図９に示すように、レバー部材４３ｂを閉じた状態とした際に、カバー部材４３ａの内部に通されたワイヤー６を押し込む。つまり、突出部４３ｈの突出量は、レバー部材４３ｂを閉じた状態とした際に、ワイヤー６を押し込み、側部４１の第１収納部４１ｃから固定部材７を引き出すことができる、突出量に設定される。なお、突出部４３ｈの先端部は、ワイヤー６の損傷を防ぐために、丸みをおびた形状とされている。 The protruding portion 43 h protrudes inward of the tray 4. As shown in FIG. 9, the protrusion 43h pushes the wire 6 passed through the inside of the cover member 43a when the lever member 43b is closed. That is, the protruding amount of the protruding portion 43h is set to a protruding amount that allows the wire 6 to be pushed in and the fixing member 7 to be pulled out from the first storage portion 41c of the side portion 41 when the lever member 43b is closed. Is done. Note that the tip of the protrusion 43 h has a rounded shape to prevent damage to the wire 6.

ちなみに、レバー部材４３ｂは、図１０に示す板バネ４３ｊ等の付勢部材によって、当該レバー部材４３ｂを開く方向に付勢される構成であることが好ましい。板バネ４３ｊの一端部は、例えばレバー部材４３ｂの右側部に接続される。板バネ４３ｊの他端部は、例えばカバー部材４３ａに接続される。 Incidentally, the lever member 43b is preferably configured to be biased in the direction of opening the lever member 43b by a biasing member such as a leaf spring 43j shown in FIG. One end of the leaf spring 43j is connected to, for example, the right side of the lever member 43b. The other end of the leaf spring 43j is connected to the cover member 43a, for example.

また、図１０等に示すように、レバー部材４３ｂの閉じた状態を維持するロック機構４４を備えていることが好ましい。ロック機構４４は、レバー部材４３ｂにおける本体部４３ｇの左側部に形成された切り欠き部４４ａ、切り欠き部４４ａに嵌合される爪部４４ｂを備える。爪部４４ｂは、板バネ４４ｃ等の付勢部材を介してカバー部材４３ａに接合されている。このとき、板バネ４４ｃは、爪部４４ｂが切り欠き部４４ａに嵌合された状態で自然状態（復元力が発現しない状態）とされている。 Moreover, as shown in FIG. 10 etc., it is preferable to provide the lock mechanism 44 which maintains the closed state of the lever member 43b. The lock mechanism 44 includes a notch 44a formed on the left side of the main body 43g of the lever member 43b, and a claw 44b fitted to the notch 44a. The claw portion 44b is joined to the cover member 43a via a biasing member such as a leaf spring 44c. At this time, the leaf spring 44c is in a natural state (a state in which no restoring force is expressed) in a state where the claw portion 44b is fitted into the notch portion 44a.

このような構成により、ユーザが爪部４４ｂを左方向に回転させると、当該爪部４４ｂと切り欠き部４４ａとの嵌合状態が解除され、板バネ４３ｊの復元力によって、レバー部材４３ｂが開いた状態となる。一方、ユーザが爪部４４ｂを左方向に回転させ、レバー部材４３ｂを閉じた状態とし、爪部４４ｂを解放すると、板バネ４４ｃの復元力によって、爪部４４ｂが切り欠き部４４ａに嵌合され、レバー部材４３ｂが閉じた状態に維持される。 With such a configuration, when the user rotates the claw portion 44b in the left direction, the fitting state between the claw portion 44b and the notch portion 44a is released, and the lever member 43b is opened by the restoring force of the leaf spring 43j. It becomes a state. On the other hand, when the user rotates the claw portion 44b in the left direction to close the lever member 43b and releases the claw portion 44b, the claw portion 44b is fitted into the notch portion 44a by the restoring force of the leaf spring 44c. The lever member 43b is maintained in a closed state.

ワイヤー６は、レバー部材４３ｂの突出部４３ｈによって張力が付加された際に、切れない強度と柔軟性を有するビニールや金属等から成る。ワイヤー６は、図３等に示すように、トレイ４の外周に沿って配設されている。すなわち、ワイヤー６は、トレイ４の左側部から前部を介して右側部に渡されている。そして、ワイヤー６は、図１０等に示すように、固定部材７に通されている。 The wire 6 is made of vinyl, metal, or the like having strength and flexibility that cannot be cut when tension is applied by the protrusion 43h of the lever member 43b. The wires 6 are disposed along the outer periphery of the tray 4 as shown in FIG. That is, the wire 6 is passed from the left side portion of the tray 4 to the right side portion through the front portion. The wire 6 is passed through the fixing member 7 as shown in FIG.

詳細には、ワイヤー６の一端部は、図６等に示すように、トレイ４の一方の側部４１に形成された第２収納部４１ｄにおける第３部分４１ｄ３の後方端部に固定されている。そして、ワイヤー６は、他端部に向かって、以下のように配設されている。 In detail, as shown in FIG. 6 etc., the one end part of the wire 6 is being fixed to the back end part of the 3rd part 41d3 in the 2nd accommodating part 41d formed in the one side part 41 of the tray 4. As shown in FIG. . And the wire 6 is arrange | positioned as follows toward the other end part.

ワイヤー６は、一方の側部４１において、第２収納部４１ｄの第３部分４１ｄ３、後側の第１収納部４１ｃに収納されている固定部材７内、第２収納部４１ｄの第１部分４１ｄ１、前側の第１収納部４１ｃに収納されている固定部材７内、第２収納部４１ｄの第２部分４１ｄ２内に収納されている、 The wire 6 has, in one side portion 41, the third portion 41d3 of the second storage portion 41d, the fixing member 7 stored in the first storage portion 41c on the rear side, and the first portion 41d1 of the second storage portion 41d. , Stored in the fixing member 7 stored in the first storage section 41c on the front side, and in the second portion 41d2 of the second storage section 41d.

さらにワイヤー６は、カバー部材４３ａの一方の切り欠き部４３ｄから内部の通路４３ｃに導き込まれ、他方の切り欠き部４３ｄから導き出される。ワイヤー６は、途中で支持部４３ｅに支持されている。 Further, the wire 6 is led from one cutout portion 43d of the cover member 43a to the internal passage 43c and from the other cutout portion 43d. The wire 6 is supported by the support part 43e on the way.

また、ワイヤー６は、他方の側部４１において、第２収納部４１ｄの第２部分４１ｄ２、前側の第１収納部４１ｃに収納されている固定部材７内、第２収納部４１ｄの第１部分４１ｄ１、後側の第１収納部４１ｃに収納されている固定部材７内、第２収納部４１ｄの第３部分４１ｄ３内に格納されている。そして、ワイヤー６の他端部は、他方の側部４１に形成された第２収納部４１ｄにおける第３部分４１ｄ３の後方端部に固定されている。 Further, the wire 6 has, in the other side portion 41, the second portion 41d2 of the second storage portion 41d, the fixing member 7 stored in the first storage portion 41c on the front side, and the first portion of the second storage portion 41d. 41d1 is stored in the fixing member 7 stored in the first storage portion 41c on the rear side and in the third portion 41d3 of the second storage portion 41d. The other end portion of the wire 6 is fixed to the rear end portion of the third portion 41 d 3 in the second storage portion 41 d formed on the other side portion 41.

固定部材７は、ワイヤー６の動作によって、トレイ４の側部４１に形成された第１収納部４１ｃから引き出される。詳細には、固定部材７は、図３及び図１１等に示すように、第１収納部４１ｃに収納可能な広さ（本実施の形態では、第１収納部４１ｃの内周と略等しい外周）を有し、且つ側部４１と略等しい厚さを有するブロック部材である。固定部材７は、ゲージ２の側部２１に接触してトレイ４を良好に固定することができる材質から成り、例えばゴム、プラスチック、金属等から成る。但し、固定部材７は、トレイ４に搭載される記憶装置３の自己振動を抑制する観点から、ゴム等の弾性部材から成ることが好ましい。 The fixing member 7 is pulled out from the first storage portion 41 c formed on the side portion 41 of the tray 4 by the operation of the wire 6. Specifically, as shown in FIGS. 3 and 11, etc., the fixing member 7 has a size that can be stored in the first storage portion 41c (in this embodiment, the outer periphery substantially equal to the inner periphery of the first storage portion 41c). ) And a block member having a thickness substantially equal to that of the side portion 41. The fixing member 7 is made of a material that can contact the side portion 21 of the gauge 2 and fix the tray 4 satisfactorily. For example, the fixing member 7 is made of rubber, plastic, metal, or the like. However, the fixing member 7 is preferably made of an elastic member such as rubber from the viewpoint of suppressing self-vibration of the storage device 3 mounted on the tray 4.

固定部材７には、図１１等に示すように、ワイヤー６が通される通路７１が形成されている。通路７１は、固定部材７の上部（但し、下部でも良い。）に形成されており、略前後方向に延在する溝部である。通路７１は、ワイヤー６を収納できる深さ及び幅寸法を有する。ここで、通路７１には、レバー部材４３ｂを開いた状態とした際に生じるワイヤー６の弛みを吸収する弛み吸収部７１ａが形成されていることが好ましい。具体的に云うと、弛み吸収部７１ａは、平面から見てトレイ４の外方に向かって略Ｖ字形状に固定部材７の上部を切り欠いた切り欠き部である。ワイヤー６に張力が付与されていない状態では、図１２に示すように、ワイヤー６は弛み吸収部７１ａに収納される。このとき、弛み吸収部７１ａの頂部７１ａ１は、張力が付加されて張った状態のワイヤー６におけるトレイ４の外方側の周縁（図１２の破線）より、トレイ４の内方側に位置する。そして、ワイヤー６に張力が付与された状態では、図１４に示すように、ワイヤー６が弛み吸収部７１ａの頂部７１ａ１を押し出し、固定部材７におけるトレイ４の外方側の面を側部４１から突出させる。そのため、弛み吸収部７１ａの頂部７１ａ１の位置は、ワイヤー６に張力が付与された際に、固定部材７が良好にトレイ４の側部４１から突出し、ゲージ２の側部２１に接触するように設定される。 As shown in FIG. 11 and the like, a passage 71 through which the wire 6 is passed is formed in the fixing member 7. The passage 71 is a groove portion that is formed in the upper portion (but may be the lower portion) of the fixing member 7 and extends substantially in the front-rear direction. The passage 71 has a depth and a width dimension that can accommodate the wire 6. Here, the passage 71 is preferably formed with a slack absorbing portion 71a that absorbs slack of the wire 6 generated when the lever member 43b is opened. More specifically, the slack absorbing portion 71a is a cutout portion formed by cutting out the upper portion of the fixing member 7 in a substantially V shape toward the outside of the tray 4 when viewed from the top. In a state where no tension is applied to the wire 6, as shown in FIG. 12, the wire 6 is stored in the slack absorbing portion 71a. At this time, the top portion 71a1 of the slack absorbing portion 71a is located on the inner side of the tray 4 from the outer periphery (dashed line in FIG. 12) of the tray 4 in the wire 6 in a tensioned state. In a state where tension is applied to the wire 6, as shown in FIG. 14, the wire 6 pushes out the top portion 71 a 1 of the slack absorbing portion 71 a, and the surface on the outer side of the tray 4 in the fixing member 7 from the side portion 41. Make it protrude. Therefore, the position of the top portion 71a1 of the slack absorbing portion 71a is such that when the tension is applied to the wire 6, the fixing member 7 projects well from the side portion 41 of the tray 4 and contacts the side portion 21 of the gauge 2. Is set.

固定部材７には、左右方向に突出する突出部７２が形成されていることが好ましい。第１収納部４１ｃには、固定部材７の左右方向の動き（突出又は収納）を許容し、且つ当該突出部７２が嵌め込まれる切り欠き部４１ｃ１が形成されており、この切り欠き部４１ｃ１に突出部７２が嵌め込まれる。これにより、固定部材７が左右方向に動く際の振れを防ぐことができる。 The fixing member 7 is preferably formed with a protrusion 72 that protrudes in the left-right direction. The first storage portion 41c is formed with a cutout portion 41c1 that allows the fixing member 7 to move in the left-right direction (protrusion or storage) and into which the protrusion 72 is fitted, and protrudes into the cutout portion 41c1. Part 72 is fitted. Thereby, it is possible to prevent shake when the fixing member 7 moves in the left-right direction.

このような構成の固定機構１を用いて、以下のようにトレイ４をゲージ２に対して挿抜する。先ず、トレイ４をゲージ２に挿入して固定する流れを説明する。
ユーザは、図２に示すように、トレイ４に記憶装置３を搭載し、レバー部材４３ｂを開いた状態として、当該トレイ４をゲージ２に挿入する。このとき、ワイヤー６は未だ弛んだ状態であり、図１２に示すように、固定部材７は側部４１の第１収納部４１ｃ内に格納されている。つまり、固定部材７は、図１３に示すように、ゲージ２の側部２１とクリアランスＣを設けた状態で配置されている。 Using the fixing mechanism 1 having such a configuration, the tray 4 is inserted into and removed from the gauge 2 as follows. First, the flow of inserting and fixing the tray 4 in the gauge 2 will be described.
As shown in FIG. 2, the user mounts the storage device 3 on the tray 4 and inserts the tray 4 into the gauge 2 with the lever member 43b opened. At this time, the wire 6 is still loose, and the fixing member 7 is stored in the first storage portion 41c of the side portion 41 as shown in FIG. That is, the fixing member 7 is arranged in a state where the side portion 21 of the gauge 2 and the clearance C are provided as shown in FIG.

次に、ユーザは、ロック機構４４の爪部４４ｂを左方向に回転させ、レバー部材４３ｂを閉じた状態とし、爪部４４ｂを解放する。すると、板バネ４４ｃの復元力によって、爪部４４ｂが切り欠き部４４ａに嵌合され、レバー部材４３ｂが閉じた状態とされる。 Next, the user rotates the claw portion 44b of the lock mechanism 44 to the left, closes the lever member 43b, and releases the claw portion 44b. Then, the claw part 44b is fitted into the notch part 44a by the restoring force of the leaf spring 44c, and the lever member 43b is closed.

同時に、レバー部材４３ｂの突出部４３ｈは、図９に示すように、ワイヤー６を押し込む。それに伴って、ワイヤー６は張力が付加されて張った状態となり、図１４及び図１５に示すように、固定部材７は側部４１の第１収納部４１ｃから引き出され、ゲージ２の側部２１に接触する。これにより、トレイ４はゲージ２に固定され、記憶装置３の自己振動を抑制することができる。しかも、本実施の形態の固定部材７は、ブロック部材であり、ゲージ２の側部２１との接触面積が広いので、トレイ４を確実にゲージ２に固定することができる。 At the same time, the protrusion 43h of the lever member 43b pushes the wire 6 as shown in FIG. Along with this, the wire 6 is in a tensioned state, and as shown in FIGS. 14 and 15, the fixing member 7 is pulled out from the first storage portion 41 c of the side portion 41 and the side portion 21 of the gauge 2. To touch. Thereby, the tray 4 is fixed to the gauge 2 and self-vibration of the storage device 3 can be suppressed. Moreover, the fixing member 7 of the present embodiment is a block member and has a wide contact area with the side portion 21 of the gauge 2, so that the tray 4 can be reliably fixed to the gauge 2.

一方、トレイ４をゲージ２から引き抜く際には、ユーザは、爪部４４ｂを左方向に回転させる。すると、当該爪部４４ｂと切り欠き部４４ａとの嵌合状態が解除され、板バネ４３ｊの復元力によって、レバー部材４３ｂが開いた状態となる。 On the other hand, when pulling out the tray 4 from the gauge 2, the user rotates the claw portion 44b in the left direction. Then, the fitting state between the claw portion 44b and the notch portion 44a is released, and the lever member 43b is opened by the restoring force of the leaf spring 43j.

同時に、レバー部材４３ｂの突出部４３ｈは、ワイヤー６への押し込みを解除するので、ワイヤー６が弛み、固定部材７のゲージ２の側部２１への接触が解除される。そのため、ユーザは簡単にトレイ４をゲージ２から引き抜くことができる。 At the same time, the protrusion 43h of the lever member 43b releases the pushing into the wire 6, so that the wire 6 is loosened and the contact of the fixing member 7 with the side portion 21 of the gauge 2 is released. Therefore, the user can easily pull out the tray 4 from the gauge 2.

このような固定機構１は、工具やネジ等を用いることなく、トレイ４のゲージ２に対する挿抜を行うことができる。しかも、固定機構１は、トレイ４を確実にゲージ２に固定することができ、記憶装置３の自己振動による当該記憶装置３への悪影響を抑えることができる。つまり、上述の固定機構１は、簡単な構成でトレイ４の挿抜容易性と防振性能を両立することができる。 Such a fixing mechanism 1 can insert and remove the tray 4 with respect to the gauge 2 without using tools, screws, or the like. Moreover, the fixing mechanism 1 can reliably fix the tray 4 to the gauge 2, and can suppress adverse effects on the storage device 3 due to the self-vibration of the storage device 3. That is, the above-described fixing mechanism 1 can achieve both the ease of inserting and removing the tray 4 and the vibration-proof performance with a simple configuration.

本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。
例えば、上記実施の形態のワイヤー６は、端部を第２収納部４１ｄの第３部分４１ｄ３の後端部に接続したが、この限りでない。すなわち、ワイヤー６は、図１６に示すように、一度後方（往路側）に向かって延在させてから、側部４１の後部に設けたプーリ４５を介して、前方（復路側）に向かって延在させて、端部を側部４１の前部に接続しても良い。このとき、側部４１及び固定部材７には、往路側のワイヤー６及び復路側のワイヤー６が収納される収納部をそれぞれ形成しても良く、統一して形成しても良い。
例えば、上記実施の形態では、被固定部材としてゲージ２を用い、振動源として記憶装置３を用いたが、この限りでない。 The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
For example, although the end of the wire 6 of the above embodiment is connected to the rear end of the third portion 41d3 of the second storage portion 41d, this is not restrictive. That is, as shown in FIG. 16, the wire 6 once extends toward the rear (outward path side) and then toward the front (return path side) via the pulley 45 provided at the rear portion of the side portion 41. The ends may be extended and connected to the front part of the side part 41. At this time, the side portion 41 and the fixing member 7 may each be formed with a storage portion for storing the wire 6 on the forward path side and the wire 6 on the return path side, or may be formed in a unified manner.
For example, in the above embodiment, the gauge 2 is used as the member to be fixed and the storage device 3 is used as the vibration source.
