Abstract
A flexible magnetic disc drive apparatus which comprises a disc clamper assembly which is operated in interlock with a door to hold a flexible magnetic disc between the disc clamper assembly and spindle, a link mechanism for connecting the disc clamper assembly to the door, wherein the link mechanism comprises a door lever which is rotatably fitted at one end to the housing of the flexible magnetic disc apparatus in the vicinity of the disc clamper assembly, and is connected at the other end to the door and whose intermediate part is provided with a projection, and a clamper hanger which is rotatably fitted at one end to the housing between the door and the projection and is connected at the other end to the clamper hanger, and wherein, when the door is opened, the door lever pushes the clamper hanger upward to lift the disc clamper assembly above the spindle, and, when the door is closed, the clamper hanger is elastically brought downward by the urging force of the plate spring fitted to the door lever to let the disc clamper assembly fall, thereby causing the disc to be held between said clamper hanger and spindle.
