Optical disk reproducing apparatus and reproducing method
View Patent ↗An optical disk reproducing apparatus of a front loading type including an optical disk insertion assembly, which has a disk insertion port into which optical disks such as CDs and DVDs are inserted, and a disk transfer assembly which transfers the optical disks to the reproduction mechanism where the disks are reproduced. The optical disk insertion assembly and the disk transfer assembly are caused to slide forward so as to project out from the front surface of the reproducing apparatus and then caused to pivot to a position where the disk insertion port is outside the front surface of the reproducing apparatus so as to be directly observed when optical disks are inserted and removed.
1. An optical disk reproducing apparatus including a reproduction means that reproduces information recorded on an optical disk, wherein said reproducing apparatus is comprised of:
a mainbody,
an optical disk insertion means disposed in a front surface of said main body and has a disk insertion port in an upper surface thereof into which an optical disk is inserted, and
a disk holder which supports said optical disk that has been inserted in said optical disk insertion means mad transfers said optical disk to said reproduction means, and
a disk insertion port opening means which moves said optical disk insertion means and said disk holder toward said front surface of said main body and a pivot motion that positions said disk insertion port outside of said main body by a sliding movement of said disk insertion port opening means in a direction parallel to the front surface of said main body.
2. The optical disk reproducing apparatus according to claim 1 , wherein said optical disk insertion means includes a first shaft and a second shaft each provided in parallel to the front surface of the main body, and
said disk insertion port opening means includes a pair of slide cams, the slide cams each being slidable in parallel to the front surface of the main body, and each of which includes a first groove having a first oblique section, the first shaft being located in the first groove, and a second groove having a second oblique section and a straight section, the second oblique section being shorter than the first oblique section and the second shaft being located in the second groove,
wherein, in use, parallel sliding of said disk insertion means causes the movement of said optical disk insertion means and said disk holder toward said front surface of said main body, as a result of a sliding movement of the first and second shafts along the oblique sections of the first and second grooves, and then causes the pivot motion that positions said disk insertion port outside of said main body, as a result of a sliding movement of the first shaft along the oblique section of the first groove and movement of the second shaft along the straight section of the second of groove.
3. The optical disk reproducing apparatus according to claim 2 , wherein the pivot motion is about an imaginary axis of rotation that is positioned further toward the front of said main body then a connection point of said optical disk insertion means and said disk insertion port opening means.
4. The optical disk reproducing apparatus according to claim 3 further comprising a drive means for moving the disk holder between a disk insertion position and a disk reproduction position.
5. The optical disk reproducing apparatus according to claim 2 , further comprising a drive means for moving the disk holder between a disk insertion position and a disk reproduction position.
6. The optical disk reproducing apparatus according to claim 5 further comprising a slide plate for moving the disk holder and the disk insertion port opening means synchronously.
7. The optical disk reproducing apparatus according to claim 1 , wherein the pivot motion is about an imaginary axis of rotation that is positioned further toward the front of said main body than a connection point of said optical disk insertion means and said disk insertion port opening means.
8. The optical disk reproducing apparatus according to claim 7 further comprising a drive means for moving the disk holder between a disk insertion position and a disk reproduction position.
9. The optical disk reproducing apparatus according to claim 1 further comprising a drive means for moving the disk holder between a disk insertion position and a disk reproduction position.
10. The optical disk reproducing apparatus according to claim 9 further comprising a slide plate for moving the disk holder and the disk insertion port opening means synchronously.
11. A reproducing method for an optical disk reproducing apparatus comprising:
a main body,
an optical disk insertion means disposed in a front surface of said main body and has a disk insertion port in an upper surface thereof into which an optical disk is inserted, and
a disk holder which supports said optical disk inserted in said optical disk insertion means and transfers said optical disk to said reproduction means, and
a disk insertion port opening means for moving said optical disk insertion means and said disk holder toward said front surface of said main body and causing a pivot motion that positions said disk insertion port outside of said main body;
the reproducing method comprising the steps of:
moving said optical disk insertion means and said disk holder toward said front surface of said main body, by a sliding movement of said disk insertion port opening means in a direction parallel to the from surface of said main body;
pivoting said optical disk insertion means and said disk bolder about an imaginary axis of rotation that is positioned further toward the front of said main body than a connection point of said optical disk insertion means end said disk insertion port opening means, by a further sliding movement of said disk insertion port opening means in a direction parallel to the front surface of said main body, such that said optical disk insertion means and said disk holder are at a position in which a disk can be inserted in the disk insertion port.
