Claims (9)

[Claims] 1. A body portion having a first disc drive portion on an upper surface portion and a second disc drive portion on a lower surface portion, and an upper surface rotatably attached to the main body portion. A disc player device comprising: an upper lid portion that opens and closes a portion; and a lower lid portion that is rotatably attached to the main body portion and that opens and closes a lower surface portion of the main body portion. 2. An opening lid knob slidably arranged with respect to the main body portion, wherein the opening lid knob closes the upper lid portion and the lower lid portion at the initial position with the upper surface portion and the lower surface portion of the main body portion closed. It is supposed that it is locked at the closed position where it is closed, and when it is slid to one side, the hook to the upper lid is released, and when it is slid to the other side, the hook to the lower lid is released. The disc player device according to claim 1. 3. A plurality of lid-opening detection switches arranged corresponding to each lid portion, and a control means to which the lid-opening detection output output from each of the lid-opening detection switches is supplied. The disc player device according to claim 1, wherein the means stops the operation of the disc drive portion corresponding to the opened lid portion based on the lid detection output. 4. A body portion having a first disc drive portion on an upper surface portion and a second disc drive portion on a lower surface portion, and an upper surface rotatably attached to the body portion. An upper lid that opens and closes the main body, a lower lid that is rotatably attached to the main body, and a lower lid that opens and closes the lower surface of the main body, and the main body that is attached to either one of the lids. And a third disc drive unit disposed so as to face the unit. 5. An opening lid knob slidably arranged with respect to the main body portion, wherein the opening lid knob closes the upper lid portion and the lower lid portion at the initial position with the upper surface portion and the lower surface portion of the main body portion closed. It is supposed that it is locked at the closed position where it is closed, and when it is slid to one side, the hook to the upper lid is released, and when it is slid to the other side, the hook to the lower lid is released. The disc player device according to claim 4. 6. A control means comprising: a plurality of lid opening detection switches arranged corresponding to each lid portion; and a control means to which an lid opening detection output output from each of the lid opening detection switches is supplied. The disc player device according to claim 4, wherein the means stops the operation of the disc drive portion corresponding to the opened lid portion based on the lid opening detection output. 7. A main body portion having a first disc drive portion on an upper surface portion and a second disc drive portion on a lower surface portion, and an upper surface of the main body portion rotatably attached to the main body portion. An upper lid portion that opens and closes the main body portion, and a sub-casing portion that is rotatably attached to the main body portion on the lower surface side of the main body portion and that opens and closes the lower surface portion of the main body portion by contacting and separating from the main body portion. A third disk drive unit disposed on the lower surface of the sub-housing, and a third disk drive unit rotatably attached to the sub-housing to open and close the lower surface of the sub-housing. A disc player device having a lid. 8. An opening lid knob slidably arranged with respect to the main body portion, wherein the opening lid knob includes an upper lid portion and a sub-casing portion at an initial position, and an upper lid portion and a lower lid portion of the main body portion. The lid is locked at a closed position, and when it is slid to one side, the latch to the upper lid is released, and when it is slid to the other side, the latch to the sub-casing is released. The disc player device according to claim 7, which is made. 9. A plurality of lid opening detection switches arranged corresponding to each lid portion and sub-casing portion, and control means to which lid opening detection outputs output from the respective lid opening detection switches are supplied. 8. The disc player device according to claim 7, wherein the control means stops the operation of the disc drive unit corresponding to the opened lid portion or sub-housing portion based on the lid opening detection output. .
