第 1スライ ド板 4が矢印 e方向ヘスライ ドすると、 第 1 スライ ド板 4 に構成されたピン 5は第 2スライ ド板 6 に形成されたス リ ツ ト 7の搬送 ローラ 1 1側の端部に当接し、 第 2スライ ド板 6 を矢印 e方向ヘスライ ドさせる。  When the first slide plate 4 slides in the direction of the arrow e, the pins 5 formed on the first slide plate 4 are moved to the end of the slit 7 formed on the second slide plate 6 on the side of the conveying roller 11. And slide the second slide plate 6 in the direction of arrow e.
この結果、 第 2 スライ ド板 6 に形成されたラ ック部 1 0 もギア 9 と嚙 み合って、 ギア 9は第 1 スライ ド板 4および第 2 スライ ド板 6 を矢印 e 方向ヘスライ ドさせる。  As a result, the rack portion 10 formed on the second slide plate 6 also meshes with the gear 9, and the gear 9 slides the first slide plate 4 and the second slide plate 6 in the direction of the arrow e. Let it.
第 2スライ ド板 6 が矢印 e方向ヘスライ ドされると、 第 2スライ ド板 6 に形成された S字形状の長孔 5 5 と係合している、 第 7図に示す昇降 アーム 1 3の延長部 1 3 aに構成されたピン 1 4は、 第 8図に示すよう に S字形状の長孔 5 5の上側の端部へスラィ ドされ、 この結果、 第 7図 に示すよう に昇降アーム 1 3は軸 1 3 bを中心にして他印 C方向へ回動 し、 搬送ローラ支持レバー 1 2 を矢印 Y方向へ回動させ、 搬送ローラ 1 1 を第 8図に示すように下降させる。 When the second slide plate 6 is slid in the direction of the arrow e, the second slide plate 6 engages with the S-shaped elongated hole 55 formed in the second slide plate 6, and as shown in FIG. The pin 14 formed on the extension 13a of the arm 13 is slid to the upper end of the S-shaped elongated hole 55 as shown in FIG. 8, and as a result, as shown in FIG.

The clamper 19 formed in the section clamps the CD 200 on the turntable from above.
( C D取り出し動作）  (CD extraction operation)
この C D取り出し動作においては、 前記駆動モータは C D装填動作時 とは逆の方向へ回転する。 このため、 ギア 9は第 8図に示す状態で右回 りで回転し、 第 1スライ ド板 4および第 2スライ ド板 6 を矢印 E方向へ スライ ドさせる。  In this CD take-out operation, the drive motor rotates in a direction opposite to that in the CD loading operation. Therefore, the gear 9 rotates clockwise in the state shown in FIG. 8, and slides the first slide plate 4 and the second slide plate 6 in the direction of arrow E.
第 2スライ ド板 6が矢印 E方向ヘスライ ドすると、 第 2スライ ド板 6 に構成されているピン 1 5 がクランプレバ一支持部材 1 Ί aのカム面 1 6 と当接し、 クランプレバ一支持部材 1 7 aを回動軸 1 8 を中心に矢印 D方向へ回動させ、 第 2 図に示す状態となり、 クランパー 1 9 とターン テーブルとによる C D 2 0 0の挟持を開放し、 クランプレバ一 1 Ί と C D 2 0 0 との関係は第 6 図に示すよう になる。  When the second slide plate 6 slides in the direction of the arrow E, the pin 15 formed on the second slide plate 6 comes into contact with the cam surface 16 of the clamp lever support member 1a, and the clamp lever support member 1 7a is rotated in the direction of arrow D about the rotation shaft 18 so that the state shown in Fig. 2 is reached, the clamping of CD200 by the clamper 19 and the turntable is released, and the clamp lever 1 The relationship with CD 200 is as shown in FIG.
一方、 第 2 スライ ド板 6の矢印 E方向の移動によ り、 S字形状の長孔 5 5 と係合しているピン 1 4は、 第 8図に示す状態から S字形状の長孔 5 5内を摺動して S字形状の長孔 5 5の下側の端部へ移動し、 この結果 、 昇降アーム 1 3は第 7図に示す矢印 c方向へ回動し、 搬送ローラ 1 1 が上昇して C D 2 0 0の裏面に当接し、 搬送ローラ支持レバー 1 2 と搬 送ローラ 1 1は第 2図に示す状態となる。 On the other hand, when the second slide plate 6 moves in the direction of the arrow E, the S-shaped long hole is formed. The pin 14 engaged with 5 5 slides in the S-shaped elongated hole 55 from the state shown in Fig. 8 and moves to the lower end of the S-shaped elongated hole 55. As a result, the elevating arm 13 rotates in the direction of arrow c shown in FIG. 7, and the transport roller 11 rises and abuts against the back surface of the CD 200, and is transported to the transport roller support lever 12. The roller 11 is in the state shown in FIG.
このとき、 搬送ローラ 1 1 は作動している駆動モー夕によ りギアュニ ヅ ト Gが駆動し第 7図に示す A A方向に回転しているため、 回転してい る搬送ローラ 1 1 によ り C D 2 0 0は装置の外へ排出される。  At this time, the conveyance roller 11 is rotated by the rotating drive roller 11 in the AA direction shown in FIG. The CD 2000 is ejected out of the device.
そして、 第 1スライ ド板 4のラ ック部 8 と第 2スライ ド板 6のラ ヅク 部 1 0がギア 9から離脱すると、 図示していないパネによ り第 1スライ ド板 4および第 2スライ ド板 6は矢印 E方向へさらに移動し、 第 1 スラ ィ ド板 4および第 2スライ ド板 6は第 2図に示す初期状態の位置へ戻る 以上の C D排出時の動作は、 小径ディスクおよび大径ディ スクともに 共通であるが、 小径ディ スクの場合には上昇した搬送ローラ 1 1 が小径 ディ スクのエッジに突き当たる可能性があるため、 第 2スライ ド板 6の 矢印 E方向の移動によ り、 第 2スライ ド板 6 に設けたピン 2 1のカム面 2 2 aに対する作用によ り、 レバ一 2 2を軸 2 3 を中心にして矢印 M方 向へ回動させ、 小径ディ スクの搬送ローラ当接側の周辺部を上方へ持ち 上げることで、 小径ディ スクのエッジに搬送ローラ 1 1 が突き当たるこ とのないようにする。  When the rack portion 8 of the first slide plate 4 and the rack portion 10 of the second slide plate 6 separate from the gear 9, the first slide plate 4 and the second slide plate 4 The second slide plate 6 moves further in the direction of arrow E, and the first slide plate 4 and the second slide plate 6 return to the initial positions shown in Fig. 2. Both the disk and the large-diameter disk are common.However, in the case of a small-diameter disk, there is a possibility that the raised transport roller 11 may hit the edge of the small-diameter disk. The movement causes the pin 21 provided on the second slide plate 6 to act on the cam surface 22 a, thereby rotating the lever 22 in the direction of arrow M about the shaft 23, By lifting up the periphery of the small-diameter disc on the side of the roller contact, the small-diameter disc Make sure that the transport roller 11 does not hit the edge.
( M D装填動作）  (MD loading operation)
M D 2 4を C D / M D揷入部における M Dの挿入口へ挿入すると、 第 2 1 図に示すように、 挿入された M D 2 4の先端の辺が M D挿入口遮蔽 蓋 1 1 2 と当接する。 この結果、 M D挿入口遮蔽蓋 1 1 2は矢印 Q方向 へ回動し、 拡開レバー 1 1 1 の一端を上方へ持ち上げる。 拡開レバー 1 1 1の他端は軸 1 1 1 aを中心にして回動し、 突片 2 5 bを下方へ押し 下げるため、 M Dホルダ開口部構成部材 2 5 aは矢印 r方向へ開き、 M Dホルダ 2 5の開口部を拡開させる。 この状態で、 M D 2 4をさらに押 し込むと、 M D 2 4はM Dホルダ 2 5 に揷入される。 第 1 0図はこの状 態を示している。 When the MD 24 is inserted into the MD insertion slot in the CD / MD 揷 insertion section, as shown in FIG. 21, the tip side of the inserted MD 24 comes into contact with the MD insertion slot cover 1 1 2. As a result, the MD insertion cover 1 1 2 rotates in the direction of arrow Q, and lifts one end of the expansion lever 1 1 1 upward. Spread lever 1 1 The other end of 1 rotates around the axis 1 1 1a and pushes down the protruding piece 25b, so that the MD holder opening component 25a opens in the direction of the arrow r, and the MD holder 2 Expand the opening of 5. When the MD 24 is further pressed in this state, the MD 24 is inserted into the MD holder 25. FIG. 10 shows this state.
M Dホルダ 2 5 に M D 2 4が揷入されると、 図示していないセンサが これを検出し、 図示していない前記駆動モー夕を動作させ、 ギアュニッ ト Gを駆動させる。 この結果、 図示しない部材によ り第 3スライ ド板 2 6が第 1 4図に示すように矢印 e方向へ移動し、 第 3スライ ド板 2 6 に 形成されたラ ック部 2 7がギア 2 8 に嚙み合い、 以後、 ギア 2 8の回転 によ り第 3スライ ド板 2 6 は矢印 e方向へ移動される。 中継部材 4 7の ビン 4 8は S字形状の長孔 4 9 と係合しているため、 第 1 5図に示すよ うに矢印 j 方向に回動し、 中継部材 4 7のピン 5 0が係合した円弧形状 の長孔 5 1 を有した中間部材 5 2が第 3スライ ド板 2 6 と同方向へ移動 する。  When the MD 24 is inserted into the MD holder 25, a sensor (not shown) detects this, and the drive mode (not shown) is operated to drive the gear unit G. As a result, the third slide plate 26 moves in the direction of arrow e as shown in FIG. 14 by a member (not shown), and the rack portion 27 formed on the third slide plate 26 is moved.
