ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an improved disk label sticking device, and more particularly to a disk sticking device in which a label can be flatly and evenly adhered to a compact disk or optical disk, and in which the overall size of the device can be reduced to facilitate packaging, storage, and transportation.
(b) Description of the Prior Art
Electronic recording devices and data carriers, such as compact disks and optical disks are widely used today. These disks generally have an annular label adhered to a back side thereof. The label is printed by using a printing machine or a printer, and is adhered to the disk by hand or using a label-sticking device. If the label is adhered by hand, the disk may be accidentally damaged, and the efficiency is poor. Besides, the label cannot be adhered flatly or evenly to the disk. In using a label sticker device, an adhesive backed label is placed reversely on a fixed label-bearing seat, and a disk is placed reversely on a receiving seat. By pressing the receiving seat downwardly, the disk is caused to adhere to the label. When pressure is released, and the receiving seat is pushed upward by an elastic force, the disk can then be removed. However, since the label is not always placed flat, and the disk may deviate when the receiving seat displaces downwardly, the label adhered to the disk may not be even and flat. Oftentimes, the worker has to press or spread the label evenly by hand, which is inefficient.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide an improved disk label sticking device whereby a label can be adhered to a compact disk or optical disk in a flat and even manner. According to this object, the present invention comprises a base, a label bearing seat, and a receiving seat. The base includes an upper cover and a lower base. The lower base is provided with annular seats at suitable positions for receiving elastic elements. The label-bearing seat is centrally provided with a circular through hole for receiving an annular label. The receiving seat is placed inside the circular through hole of the label-bearing seat. It has a bottom side thereof pressing against a central elastic element disposed below, and a top side provided with a securing portion for receiving a central insert hole of a compact or optical disk. The upper cover of the base is centrally formed with a through hole that has partition plates formed at side edges thereof. The lower base is provided with projecting partition pieces that define slanting guide slots with the partition plates of the upper cover. The label bearing seat is fitted in the through hole of the upper cover and has a lower side pressing against the elastic elements on the lower base. The label-bearing seat further has side edges formed with guide flanges that extend into the slanting guide slots of the base, and a bottom portion that defines a suitable clearance with the lower base. An adhesive-backed annular label can be placed reversely on the label-bearing seat, and a compact disk or an optical disk can be placed reversely on the receiving seat. When the receiving seat is pressed to displace downwardly, the disk will adhere to the label. The label-bearing seat can further be brought to rotate along the slanting guide slots to press the label flat so that the label can adhere to the disk flatly and evenly.
Another object of the present invention is to provide an improved disk label-sticking device the size of which can be reduced to facilitate packaging, storage and transportation. According to this object, the receiving seat can be pressed downwardly so that it is temporarily retained within the through hole of the label bearing seat by guide slots or guide tracks of the label bearing seat due to an upward urging force of the elastic element below.
