Disc drive with lock release unit
View Patent ↗Provided is a disc drive including a tray which receives a disc thereon, slides into and out of a main chassis, and includes a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc. The disc drive also includes a lock release unit which is driven by the pickup transporting unit to release locking of the tray from the main chassis, and includes a lock lever unit which includes a supporting hole for rotating the lock lever unit, and a hook unit to be combined with a locking protrusion arranged at the main chassis.
1. A disc drive comprising:
a tray which receives a disc thereon, slides into and out of a main chassis, and comprises a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc; and
a lock release unit which is driven by the pickup transporting unit to release locking of the tray from the main chassis, and includes a lock lever unit which comprises:
a body;
a supporting hole, into which a rotation shaft arranged at the tray is inserted, for rotating the lock lever unit; and
a hook unit to be combined with a locking protrusion arranged at the main chassis.
2. The disc drive of claim 1 , wherein
the supporting hole is formed by a burring process onto the body; and
the hook unit extends a predetermined length from the body and is to be combined with the locking protrusion.
3. The disc drive of claim 2 , wherein the supporting hole protrudes from the rear surface of the body to a predetermined height.
4. The disc drive of claim 3 , wherein the lock release unit comprises:
a link unit which is rotatably installed on the tray and comprises a power transmitting unit which receives rotational force when combined with the pickup transporting unit;
a connecting unit which is rotatably installed on the tray, which is connected to the lock lever unit and the link unit, and which rotates the lock lever unit via a rotational force of the link unit; and
a spring which is fixed to the lock lever unit and the connecting unit and applies an elastic force in the direction in which the hook unit is combined with the locking protrusion.
5. The disc drive of claim 4 , wherein the lock lever unit comprises:
a rotational force receiving unit which contacts the connecting unit and receives a rotational force; and
a spring fixing unit to which a first end of the spring is fixed.
6. The disc drive of claim 4 , wherein the link unit further comprises an interrupter which interrupts the feed guide from connecting the pickup base to the pickup transporting unit, and
when the link unit rotates as the interrupter collides with the feed guide, the power transmitting unit is combined with the pickup transporting unit.
7. The disc drive of claim 4 , wherein the power transmitting unit is formed as a protrusion having a predetermined height which is to be combined with a lead screw of the pickup transporting unit.
8. The disc drive of claim 7 , further comprising a pickup base position limiting unit which limits a position of the pickup base when the power transmitting unit is combined with the lead screw.
9. The disc drive of claim 4 , wherein the link unit further comprises an interrupter which interrupts the feed guide from connecting the pickup base to the pickup transporting unit, and
when the link unit rotates as the interrupter collides with the feed guide, the power transmitting unit is combined with the pickup transporting unit.
10. The disc drive of claim 4 , wherein the power transmitting unit is formed as a protrusion having a predetermined height which is to be combined with a lead screw of the pickup transporting unit.
11. The disc drive of claim 10 , further comprising a pickup base position limiting unit which limits a position of the pickup base when the power transmitting unit is combined with the lead screw.
12. A disc drive comprising:
a tray which receives a disc thereon, slides into and out of the main chassis, and comprises a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc;
a lock release unit which is driven by the pickup transporting unit to release locking of the tray from the main chassis, and includes a lock lever unit, which comprises:
a supporting hole formed for rotating the lock lever unit; and
a hook unit to be combined with a locking protrusion arranged at the main chassis;
a link unit which is rotatably installed on the tray and comprises a power transmitting unit which receives a rotational force by being combined with the pickup transporting unit;
a connecting unit which is rotatably installed on the tray, is connected to the lock lever unit and the link unit, and rotates the lock lever unit via a rotational force of the link unit; and
a spring which is fixed to the lock lever unit and the connecting unit and applies an elastic force in the direction in which the hook unit is combined with the locking protrusion.
13. The disc drive of claim 12 , wherein the lock lever unit comprises:
a body;
the supporting hole into which a rotation shaft arranged at the tray is inserted for rotating the lock lever unit, wherein the supporting hole is formed by a burring process onto the body; and
the hook unit which extends a predetermined length from the body and is to be combined with the locking protrusion.
14. The disc drive of claim 13 , wherein the supporting hole protrudes from the rear surface of the body to a predetermined height.
15. The disc drive of claim 12 , wherein the lock lever unit comprises:
a rotational force receiving unit which contacts the connecting unit and receives a rotational force; and
a spring fixing unit to which a first end of the spring is fixed.
16. A disc drive comprising:
a tray which receives a disc thereon, slides into and out of the main chassis, and comprises a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc;
a lock release unit which is driven by the pickup transporting unit to release locking of the tray from the main chassis, and includes a lock lever unit, which comprises:
a supporting hole formed for rotating the lock lever unit; and
a hook unit to be combined with a locking protrusion arranged at the main chassis; and
a link unit which is rotatably installed on the tray and comprises a power transmitting unit which receives a rotational force by being combined with the pickup transporting unit.
17. The disc drive of claim 16 , wherein the supporting hole protrudes from the rear surface of the body to a predetermined height.
18. The disc drive of claim 16 , wherein the supporting hole receives a rotation shaft therein for rotating the lock lever unit.
