Abstract
Disclosed herein is a disc loading device applied to small-sized and slim type disc players. The disc loading device may include a first guide lever, a second guide lever, a trigger lever, a chucking unit, a slider, and a connecting unit. The connecting unit may be selectively operatively connected to the second guide lever, upon loading a first disc or a second disc, to change a timing at which a rotational force of the trigger lever may be transmitted to the slider.
Claims22
A disc loading device, comprising:
- a main frame and a sub frame defining a loading region to allow a first disc and a second disc having different diameters to be loaded thereto;
- a first guide lever rotatably mounted outside the loading region on the sub frame and extending into the loading region to interfere with the first disc or second disc when the first disc or second disc is loaded into the disc loading device;
- a second guide lever rotatably mounted outside the loading region on the sub frame and extending into the loading region to interfere with the second disc when the second disc is loaded into the disc loading device;
- a trigger lever rotatably mounted outside the loading region on the main frame and extending into the loading region to interfere with the discs;
- a chucking unit to chuck the first disc or the second disc located at the loading region;
- a slider reciprocatably mounted outside the loading region to operate the chucking unit;
- and
- a connecting unit disposed between the trigger lever and the slider to transmit a rotational force of the trigger lever to the slider,
- wherein the connecting unit is selectively operatively connected to the second guide lever, upon loading the first disc or the second disc, to change a timing at which the rotational force of the trigger lever is transmitted to the slider.
6 more elements
A disc loading device, comprising:
- a main frame and a sub frame defining a loading region to allow a first disc and a second disc having different diameters to be loaded thereto;
- a plurality of first guide levers linked to each other and rotatably mounted outside the loading region and extending into the loading region;
- and
- a plurality of second guide levers linked to each other and rotatably mounted outside the loading region and extending into the loading region, the second guide levers constraining or releasing the first guide levers, wherein
- the second guide levers constrain the first guide levers upon loading the first disc to the loading region such that a chucking position of the first disc is decided by the first guide levers, and
- the second guide levers release the first guide levers upon loading the second disc to the loading region such that a chucking position of the second disc is decided by the first guide levers and the second guide levers moving out of the loading region.
3 more elements
A disc loading device, comprising:
- a lower frame and an upper frame defining a disc placement region to allow discs of different sizes to be placed thereon;
- a narrow pair of pivoting levers facing each other to guide discs into the disc placement region;
- a wide pair of pivoting levers facing each other to guide discs into the disc placement region;
- a first elastic member mounted in the upper frame to provide opposite forces to the narrow pair of pivoting levers;
- and
- a second elastic member mounted on one of the wide pair of pivoting levers to provide a rotating force to one of the wide pair of pivoting levers.
3 more elements
A disc loading device, comprising:
- a first frame and a second frame to define a loading region;
- a trigger lever having an end disposed to contact a first disc in a first loading region of the loading region;
- a plurality of levers each having an end disposed to contact a second disc in a second loading region of the loading region, a clockwise rotation of a second right-side lever is limited due to a first catching protrusion on a first right-side lever upon uploading a second disc into the loading region, and a counterclockwise rotation of a first right-side lever is limited due to a stopper on the second right-side lever upon loading a first disc into the loading region.
A disc drive apparatus, comprising:
- a controller to control the loading and unloading of small and large sized discs into the disc driving apparatus, wherein the controller further controls:
- a loading and unloading unit to advance small and large discs into the disc drive apparatus toward a loading region;
- a chucking unit to chuck small and large discs located in the loading region;
- a detecting unit to sense placement of small and large discs within the disc drive apparatus;
- a trigger lever rotatably mounted outside the loading region and extending into the loading region;
- a first guide lever rotatably mounted outside the loading region and extending into the loading region to guide small and large discs into the loading region;
- and
- a second guide lever rotatably mounted outside the loading region and extending into the loading region to guide large discs into the loading region.
