Abstract
A disk recording and/or reproducing device capable of recording data onto a disk and/or reproducing data recorded on the disk, includes a disk mounting portion for mounting the disk; a chucking portion for chucking the disk in cooperation with the disk mounting portion, the chucking portion having a disk engaging portion for engaging the disk at the start of disk loading; and a slider for supporting the chucking portion and moving the chucking portion in a radial direction of the disk between a chucking position where the disk is allowed to be chucked and a loading position where the disk loading is allowed to be started. With this arrangement, the device can be reduced in thickness.
Claims16
A disk recording and/or reproducing device for recording data onto a disk and/or reproducing data recorded on said disk, the device comprising:
- a disk mounting portion for mounting said disk;
- a chucking portion for chucking said disk in cooperation with said disk mounting portion, said chucking portion having a disk engaging portion for engaging said disk at a start of a disk loading operation;
- a slider for supporting said chucking portion and for moving said chucking portion in a radial direction of said disk between a chucking position where said disk is chucked and a loading position where said disk loading operation is started;
- and
- a locking portion adapted to be pushed by said disk being inserted so as to cancel a restricted condition of said slider;
- wherein when said restricted condition of said slider is canceled by said locking portion, said slider is moved in a loading direction by continued insertion of said disk.
A disk recording and/or reproducing device for recording data onto a disk and/or reproducing data recorded on said disk, the device comprising:
- a disk mounting portion for mounting said disk;
- a chucking portion for chucking said disk in cooperation with said disk mounting portion, said chucking portion having a disk engaging portion for engaging said disk at a start of a disk loading operation;
- a slider for supporting said chucking portion and for moving said chucking portion in a radial direction of said disk between a chucking position where said disk is chucked and a loading position where said disk loading operation is started;
- and
- a link lever engaged with said slider and adapted to be pivotally moved in concert with movement of said slider in a loading direction and having a toggle spring for biasing said slider through an engaged portion of said link lever with said slider, wherein when said slider is moved to a predetermined position in said loading direction, said toggle spring is inverted in a biasing direction from an eject direction to said loading direction.
A disk eject mechanism for ejecting a disk having already been mounted in a device, comprising:
- an eject lever adapted to be operated in a predetermined direction according to an eject instruction by a user of the device, said eject lever having a first push portion and a second push portion;
- and
- a slider adapted to be pushed by said first push portion of said eject lever and thereby moved in an eject direction in concert with operation of said eject lever in said predetermined direction to a predetermined position, and said slider being adapted to be released from said first push portion after passing said predetermined position upon operation of said eject lever and to be pushed by said second push portion, thereby being further moved in said eject direction.
