DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 2, a schematic diagram illustrates a casing structure for a card reader according to an embodiment of the present invention. As shown in FIG. 2, the casing structure 22 for the card reader includes an upper casing structure 221 and a lower casing structure 222. The card reader can be secured in the upper casing structure 221 or the lower casing structure 222 in advance. In addition, at least one side 2211 of the upper casing structure 221 has an elastic hook 22111 and a hook notch 22112. A protruding ridge 221111 is disposed on the elastic hook 22111. A force is then provided to push the protruding ridge 221111. The elastic hook 22111 then performs displacements S1 and S2 on the side 2211. Moreover, for corresponding to the side 2211 of the upper casing structure 221, a side 2221 of the lower casing structure 222 also has a protruding cylinder 22211 and a support cylinder 22212. It should be noted that other data readers like a coin machine or relative reading apparatuses are used to replace the card reader.
Referring to FIG. 3, a schematic diagram (I) illustrates the upper casing structure 221 closing the lower casing structure 222. As shown in FIG. 3, the hook notch 22112 of the upper casing structure 221 is buckled to the support cylinder 22212 of the lower casing structure 222.
Referring to FIG. 4, a schematic diagram (II) illustrates the upper casing structure 221 closing the lower casing structure 222. As shown in FIG. 4, the hook notch 22112 of the upper casing structure 221 has buckled to the support cylinder 22212 of the lower casing structure 222. The upper casing structure 221 has covered the lower casing structure 222. Under the covering condition an external force is imposed on the protruding ridge 221111 of the elastic hook 22111 of the upper casing structure 221. The elastic hook 22111 then performs the displacement motion S1 on the side 2211.
Referring to FIG. 5, a schematic diagram illustrates the upper casing structure 221 covering the lower casing structure 222 completely. As shown in FIG. 5, the hook notch 22112 of the upper casing structure 221 has buckled to the support cylinder 22212 of the lower casing structure 222. The upper casing structure 221 has covered the lower casing structure 222. Because the force pushed on the protruding ridge 221111 has been released, the elastic hook 22111 then performs the displacement S2 through a reactive force generated from a spring of the elastic hook 22111. The elastic hook 22111 is hooked the protruding cylinder 22211.
Referring to FIG. 6, FIG. 7 and FIG. 8, diagrams illustrate a casing structure for a card reader according to preferred embodiments of the present invention.
Referring to FIG. 6, a perspective drawing illustrates a casing structure for a card reader according to an embodiment of the present invention. As shown in FIG. 6, the card reader 6 includes a shell 61. The shell 61 includes an upper casing 611 and a lower casing 612. In addition, two sides 6111 of the upper casing 611 have a hook 61111 and a notch 61112. A protruding ridge 611111 is disposed on the hook 61111. An external force is then provided to push the protruding ridge 611111. The hook 61111 then performs the outward displacement S3 on the two sides 6111. Moreover, two sides 6121 of the lower casing 612 which corresponds to the two sides 6111 of the upper casing 611 also have a protruding cylinder 61211 and an axial cylinder 61212.
Referring to FIG. 7, a side elevation is according to FIG. 6. As shown FIG. 7, the hook 61111 of the upper casing 611 is buckled the protruding cylinder 61211 of the lower casing 612. The notch 61112 of the upper casing 611 is buckled the axial cylinders 61212 of the lower casing 612. The upper casing 611 then covers the lower casing 612 tightly.
Referring to FIG. 8, a top view is according to FIG. 6. As shown in FIG. 8, a user uses his thumb and first finger of one hand to push the protruding ridges 611111 of the two sides of the upper casing 611, thereby imposing an external force toward the displacement direction S4. Therefore, the upper casing 611 is easily removed from the lower casing 612.
In addition, the casing structure for the card reader disclosed by the present invention can be further applied to card readers for an automatic vending machine, a game console or relative machines. Moreover, the card reader can be replaced by other data reading apparatuses like a coin machine or other readers.
Although the features and advantages of the embodiments according to the preferred invention are disclosed, it is not limited to the embodiments described above, but encompasses any and all modifications and changes within the spirit and scope of the following claims.
