Abstract

PURPOSE:To stabilize operation by providing a blade body which interlocks with an axis turning when a cassette tray is elevated any by interposing a clutch mechanism in a rotation transmission system. CONSTITUTION:When a cassette tray is unlocked from lock plate 13 through ejecting operation, support point 12 provided to the cassette tray is pushed up and accordingly, interlock axis 8 and drive gear 15 are turned counterclockwise, clutch pin 19 inserted into a wedge-shaped groove formed with wheels 21 and 18 is pressed against spring 20 to make wheels 21 and 18 into one body, and the rotation of gear 15 is trasmitted to governor 22, thereby turning blade 25 at a high speed. As a result, a load on blade 25 increases and the elevating speed of the cassette tray is lowered. On the other hand, when the cassette tray is lowered, blade 25 never turns.
