Claims

[Scope of utility model registration request]

A pair of left and right fixed cassette holders and a pair of left and right support levers are arranged at intervals in the direction of insertion of the cassette into the cassette holder, and the four corners of the cassette are supported by the upper parts of these cassette holders and the support levers. A plurality of cassettes are stacked one above the other, and the lowest stacked cassette and the second cassette placed above it are placed on top of each other.
A pair of left and right drop levers are provided between the cassettes of the tiers and the cassettes are inserted from the opposite direction to the cassette insertion direction to support the cassettes of the second and higher tiers, and each pair of support levers and the drop levers are connected to each other. By providing a pair of interlocking left and right intermediate levers, providing a pair of left and right connecting levers that are integrally connected to each other by a connecting shaft and simultaneously driving the intermediate levers, and rotating one of the connecting levers with a cam, The rain intermediate levers are simultaneously rotated by the two connection levers, and the rain intermediate levers simultaneously rotate the support levers and the drop levers, and at this time the support levers are moved against the spring. By rotating the cassette in the cassette insertion direction and removing both support levers from the bottom of the bottom cassette in the cassette connection direction, the bottom cassette is allowed to fall under its own weight and inserted into the cassette holder. At the same time, immediately before the both support levers are removed from the lower part of the lowermost cassette in the cassette insertion direction, the two drop levers are inserted into the lower part of the second cassette from the opposite direction to the cassette insertion direction. In a cassette autochanger configured to hold cassettes of a stage or higher, in the double-acting state, the first abutted part provided on the intermediate lever is connected to the first abutted part provided on the gar. When brought into contact with each other, the support levers are locked and the surface support levers are prevented from rotating in the cassette insertion direction against the spring, and the one surface connection lever is moved from the return position. Until the rotation starts and the second contact portion provided on both connecting tabs contacts the second contact portion provided on the rain intermediate lever and rotates these rain intermediate levers. A play q is provided between them, and when both connecting levers are rotated through the range of play, the first abutting portion is released from the first abutted portion, and the supporting levers are restored. A cassette auto changer characterized in that it is configured to be unlocked in a moving position.
