Disk storage device having eject member

A disk storage device comprising:

• a head part for writing data to a storage disk inserted into the disk storage device and for reading data from the storage disk;
• an eject member which is operated when the storage disk is ejected from the disk storage device;
• a turntable for rotating and driving the storage disk thereon to perform data recording and reproducing in cooperation with the head part;
• a holder for holding a disk cartridge accommodating the storage disk, said holder placing the storage disk at a read/write position on the turntable, when the disk cartridge is inserted, by fitting a center hole of the storage disk on a spindle of the turntable;
• a slider which is disconnected from a latch lever when the disk cartridge is inserted, and is moved in a first direction substantially parallel to a direction of insertion of the disk cartridge so that the storage disk inserted in the holder is placed at the read/write position on the turntable;
• and
• a movement mechanism for moving the holder and the disk cartridge from the read/write position of the turntable to an insertion position in response to a movement of the slider in a direction opposite to the first direction when the eject member is operated,
• wherein said eject member is mounted flat on an upper portion of a frame of the disk storage device, said eject member having
• an operation part which is operated by applying an external force thereto in a direction parallel to a surface of the turntable, and
• a transfer part connected to a mounting portion at an end of the slider, said transfer part of said eject member being formed so as to extend downward from the center of the operation part, said transfer part being passed through a first opening formed in the upper portion of the frame and connected to the mounting portion of the slider so that the movement of the operation part, when the eject member is operated, is transferred to the slider via the transfer part, said slider being moved in the direction opposite to the first direction when the operation part is operated, the movement mechanism moving the holder and the disk cartridge from the read/write portion to the insertion position in response to said movement of the slider, so that the disk cartridge can be ejected from the holder at the insertion position;
• and
• wherein said operation part of said eject member is formed with a planar portion extending along the surface of the upper portion of the frame substantially parallel to the surface of the turntable, said operation part being moved with a displacement from a first position to a second position different from the first position along the surface of the upper portion of the frame, and
• wherein said eject member further comprises a set of projections extending sideways from said transfer part at portions immediately below said operation part, said projections having a first width between outside edges thereof which width is greater than a transverse width between inside edges of the first opening of the upper portion of the frame, said transverse width being measured at right angles to the first direction in which the slider is moved when the eject member is operated.
