ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a recording and/or reproducing apparatus, and particularly to a recording and/or reproducing apparatus which has an opening portion and a shutter opening and closing the opening portion.
2. Description of the Related Art
In a portable disk recording and/or reproducing apparatus, for example, a disk player such as a CD (compact disk) player or the like, the main body portion includes a main portion where a disk mounting portion and an optical pickup are located, and a cover portion for rotating with respect to the main portion for opening and closing the disk mounting portion. In such a disk player, a CD is mounted on and dismounted from the disk mounting portion in such a state that the cover portion is largely opened relative to the main portion.
In the disk player as described above, it was impossible to mount/dismount a CD on/from the disk mounting portion without using both hands due to problems of the dimension of disk diameter and of the rotary angle of cover portion of the player. In such a state that the cover portion is open, the strength becomes weak. If the cover portion is left open it may be damaged accidentally. If the cover portion is left open in the above-mentioned disk player, trash or dust enters. This results in a problem that an optical pickup is made dirty and the movement of a mechanical portion is hampered.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a recording and/or reproducing apparatus which resolves the above-mentioned problems.
According to the present invention, there is provided a recording and/or reproducing apparatus including a main body portion, a shutter mechanism, a driving mechanism, an elevator mechanism, and an ejection mechanism. The main body portion has an opening portion through which a recording medium is inserted and ejected. The shutter mechanism opens and closes the opening portion. The shutter mechanism is provided on the main body portion to be freely movable and closes the opening portion under a state where the insertion of the recording medium into the main body portion is completed. The driving mechanism drives the recording medium. The elevator mechanism moves up and down in an interlinking marker with the movement of the shutter mechanism. The elevator mechanism mounts the recording medium on the driving mechanism when the shutter mechanism is moved to a position to close the opening portion, while moving the recording medium apart from the driving mechanism when the shutter mechanism is moved to a position to open the opening portion. The ejector mechanism ejects the recording medium through the opening portion. When the shutter mechanism is moved from the position to close the opening portion to the position to open the opening portion, the ejector mechanism ejects the recording medium, which is moved apart from the driving mechanism by the elevator mechanism from the main body portion.
According to the present invention, there is provided a recording and/or reproducing apparatus of a disc-shape recording medium including a main body portion, a shutter mechanism, a driving mechanism, an elevator mechanism, and an ejector mechanism. The main body portion has an opening portion through which a disc-shaped recording medium is inserted or ejected. The shutter mechanism opens and closes the opening portion. The shutter mechanism is provided on the main portion to be freely movable and closes the opening portion at a state that the insertion of the disc-shaped recording medium into the main body portion is completed. The driving mechanism is a driving mechanism rotatably drives the disc-shaped recording medium and includes a motor to rotatably drive a table on which the disc-shaped recording medium is to be mounted and a disc table. The elevator mechanism goes up and down in an interlocking fashion with the movement of the shutter mechanism. The elevator mechanism goes down to a position lower than that of the disc table to mount the disc-shaped recording medium on the disc table when the shutter mechanism is moved to a position to close the opening portion, and lifts up the disc-shaped recording medium from the disc table when the shutter mechanism is moved to a position to open the opening portion. The ejector mechanism ejects the disc-shaped recording medium through the opening portion. The ejector mechanism ejects the disc-shaped recording medium lifted up from the disc table by the elevator mechanism when the shutter mechanism is moved from a position to close the opening portion to a position to open the opening portion.
According to the present invention, there is provided a recording and/or reproducing apparatus including a main body portion, a shutter mechanism, a driving mechanism, an elevator mechanism, and an ejector mechanism. The main body portion has an opening portion through which a recording medium is inserted or ejected. The opening portion is provided through the side surface of the main body portion. The shutter mechanism opens and closes the opening portion. The shutter mechanism is provided to be freely movable along the side surface of the main body portion and closes the opening portion under the state that the insertion of the recording medium into the main body portion is ended. The shutter mechanism moves at least two shutter members or a pair of shutter members between a position to open the opening portion and a position to close the opening portion. When the pair of the shutter members are moved in the opposite directions with each other, the opening portion is opened, when they are moved in the direction in which they become closer, the opening portion is closed. The driving mechanism drives the recording medium. The elevator mechanism goes up and down in an interlocking fashion with the movement of the shutter members. The elevator mechanism mounts the recording medium on the driving mechanism when the shutter members are moved to a position to open the opening portion, and moves the recording medium apart from the driving mechanism when the shutter members are moved to a position to open the opening portion. The ejector mechanism ejects the recording medium from the opening portion. The ejector mechanism ejects the recording medium moved apart from the driving mechanism by the elevator mechanism through the opening portion when the shutter members are moved from a position to close the opening portion to a position to open the opening portion.
