Description

そして、各回転軸39,40,41,42には、対応するカムピン43,44,45および被押圧ピン46を、それぞれ、第1および第2チャッキングピン31,32がそれぞれ第1および第2ガイド孔27,28の内側端の方向つまり第1のCD8の通路を閉じる方向に移動し、また第3および第4チャッキングピン33,34がそれぞれ第1および第2ガイド縁29,30の内側端の方向つまり第1のCD8の通路を閉じる方向に移動するように常時付勢するスプリング47,48,49,50が設けられている。その場合、2つのスプリング47,48のばね力が他の2つのスプリング49,50のばね力より若干大きく設定されている。したがって、後述するように12cmあるいは8cmの第1のCD8がそれぞれ位置決め部25a′,26′に当接した正規位置に設定された状態では、2つのスプリング47,48のばね力で第1のCD8は位置決め部25a′,26′に当接した状態に付勢されて維持され、正規位置が保持されるようになっている。 The corresponding cam pins 43, 44, 45 and the pressed pins 46 are attached to the rotating shafts 39, 40, 41, 42, respectively, and the first and second chucking pins 31, 32 are the first and second guides, respectively. It moves in the direction of the inner edges of the holes 27,28, that is, in the direction of closing the passage of the first CD8, and the third and fourth chucking pins 33, 34 are at the inner edges of the first and second guide edges 29,30, respectively. Springs 47, 48, 49, 50 are provided that constantly urge the vehicle to move in a direction, that is, in a direction that closes the passage of the first CD8. In that case, the spring force of the two springs 47, 48 is set to be slightly larger than the spring force of the other two springs 49, 50. Therefore, as will be described later, in a state where the first CD8 of 12 cm or 8 cm is set to the normal position in contact with the positioning portions 25a'and 26', respectively, the spring force of the two springs 47 and 48 is used to set the first CD8. Is urged and maintained in a state of being in contact with the positioning portions 25a'and 26', and the normal position is maintained.

更に、第1チャッキング制御部材51はスプリング56のばね力で図5(b)において常時時計方向に付勢されており、この第1チャッキング制御部材51の他の外力が加えられないときは、図5(a)および(b)に示す状態、つまり第1および第2チャッキングピン31,32がそれぞれ第1および第2ガイド孔27,28の内側端に位置するとともに第3および第4チャッキングピン33,34がそれぞれ第1および第2ガイド縁29,30の内側端にほぼ位置して、第1のCD8の通路を最も閉じた位置に設定されるようになっている。なお、スプリング56に代えてスプリング47,48,49,50の力を利用することもできる。その場合は、スプリング56が不要となるので部品点数を削減でき、コストを低減できる。 Further, the first chucking control member 51 is always urged clockwise in FIG. 5B by the spring force of the spring 56, and when another external force of the first chucking control member 51 is not applied. , FIGS. 5 (a) and 5 (b), that is, the first and second chucking pins 31, 32 are located at the inner ends of the first and second guide holes 27, 28, respectively, and the third and fourth chucks. The kingpins 33 and 34 are located substantially at the inner ends of the first and second guide edges 29 and 30, respectively, so that the passage of the first CD8 is set to the most closed position. The force of the springs 47, 48, 49, 50 can be used instead of the spring 56. In that case, since the spring 56 is unnecessary, the number of parts can be reduced and the cost can be reduced.

また、第1チャッキング制御部材51は後述するように第1ラックスライダ79により力が加えられて、図5(b)において反時計方向にスプリング56のばね力に抗して回転すると、各カムピン43,44,45がガイドされるので、第1ないし第3ピン支持板35,36,37がそれぞれ回転し、第1ないし第3チャッキングピン31,32,33がそれぞれ対応する第1および第2ガイド孔27,28の外側端、第1ガイド縁29の外側端の方へ向かって、つまり第1のCD8の通路を開く方向にこれらの第1および第2ガイド孔27,28、第1ガイド縁29にガイドされて移動するようになっている。
なお、第1チャッキング制御部材51はこのような回転式に代えて、スライド式のスライダを用いることもできる。
Further, when a force is applied to the first chucking control member 51 by the first rack slider 79 and the first chucking control member 51 rotates counterclockwise against the spring force of the spring 56 in FIG. 5B, each cam pin Since 43,44,45 are guided, the first to third pin support plates 35, 36, 37 rotate respectively, and the first to third chucking pins 31, 32, 33 correspond to the corresponding first and second pins, respectively. These first and second guide holes 27,28, the first guide toward the outer end of the guide holes 27,28, toward the outer end of the first guide edge 29, that is, in the direction of opening the passage of the first CD8. It is designed to move guided by the edge 29.
The first chucking control member 51 may use a slide type slider instead of such a rotary type.

また、第1ラックスライダ79の移動により、押圧部材85の端85aが第1チャッキング制御部材51の被押圧ピン51bを押すので、第1チャッキング制御部材51が回転する。これにより、チャッキングアーム35,36,37,38が回転し、第1ないし第4チャッキングピン31,32,33,34が図18(a)のCD待機位置となる。 Further, as the first rack slider 79 moves, the end 85a of the pressing member 85 pushes the pressed pin 51b of the first chucking control member 51, so that the first chucking control member 51 rotates. As a result, the chucking arms 35, 36, 37, 38 rotate, and the first to fourth chucking pins 31, 32, 33, 34 become the CD standby positions shown in FIG. 18 (a).
