Abstract
A disc grabbing device adapted to a disc archive system for grabbing at least one disc is provided. The disc grabbing device includes a center cylinder, a drive controller and a detection device. When the disc is grabbed by the disc grabbing device, the center cylinder passes through the center hole of the disc. The drive controller is configured to control the disc grabbing device to grab the disc. The detection device is electrically connected to the drive controller to detect a surface of a disc placed on a disc tray to be grabbed, and to correspondingly transmit a drive stop signal to the drive controller to stop the operation of the disc grabbing device.
Claims12
A disc grabbing device adapted to a disc archive system for grabbing at least one disc, wherein the disc grabbing device comprises:
- a center cylinder, which passes through the center hole of a disc wherein the disc is grabbed by the disc grabbing device;
- a drive controller configured to control the disc grabbing device to pick and place the disc;
- and
- a detection device electrically connected to the drive controller to detect a surface of a disc placed on a disc tray to be grabbed, and to correspondingly transmit a drive stop signal to the drive controller to stop an operation of the disc grabbing device,
- wherein the detection device has a detection end protruded from a terminal portion of the center cylinder and located on a center axis of the center cylinder.
A disc grabbing device adapted to a disc archive system for grabbing at least one disc, wherein the disc grabbing device comprises:
- a center cylinder, which passes through the center hole of a disc wherein the disc is grabbed by the disc grabbing device;
- a drive controller configured to control the disc grabbing device to pick and place the disc;
- and
- a detection device electrically connected to the drive controller to detect a surface of a disc placed on a disc tray to be grabbed, and to correspondingly transmit a drive stop signal to the drive controller to stop an operation of the disc grabbing device, wherein the detection device comprises:
- a connecting rod slidably disposed in the center cylinder, wherein the connecting rod has a detection end protruded from a terminal portion of the center cylinder;
- a light blocking element disposed on the connecting rod;
- and
- a light sensor configured to emit and receive an optical signal,
- wherein when the detection end is pressed by the surface of the disc to be grabbed and causes the connecting rod to move, the connecting rod drives the light blocking element to shield or not to shield the optical signal,
- wherein when a shielding state of the optical signal changes, the detection device emits the drive stop signal.
