[0016] As illustrated in an schematic view of a first embodiment of this invention shown in FIG. 2A and a lateral view thereof shown in FIG. 2B, a recess 21 for loading a name card is formed in a loading deck 20 centrally and an adhesive plastic film (not shown) is laid on the recess 21 for eliminating image distortion in the event of a folded name card. The loading deck 20 is about 1 mm thick while the recess 21 is about 0.2 mm deep such that a name card is permitted to be attached as closely as possible to a contact image sensor (CIS) 22 having a view depth of 1 mm only Moreover, the width of the CIS 22 is exactly the same with that of the recess 21, and a correction slip 23 is adhered to a bottom face of the front end of the loading deck 20.

[0017] A first gear set 25 and a paired second gear set 26 are set by a bracket (not shown), and a motor 24 is implemented to drive the first gear set 25, then the second gear set 26. The teeth 25a, 26a of the first and the second gear set 25, 26 are engaged with a plurality of slots 27 formed on both sides of the loading deck 20 respectively to thereby drive the loading deck 20 to pass over the CIS sensor 22 to have a name card scanned when the motor 24 drives the first and the second gear set 25, 26.

[0018] In an schematic view of a second embodiment of this invention shown in FIG. 3A and a lateral view thereof shown in FIG. 3B, a recess 31 for loading a name card is formed in a loading deck 30 centrally and an adhesive plastic film (not shown) is laid on the recess 31 for eliminating image distortion in the case of a folded name card. The loading deck 30 is about 1 mm thick while the recess 31 is about 0.2 mm deep such that a name card is permitted to be attached as closely as possible to a contact image sensor (CIS) 32 having a view depth of 1 mm only. Moreover, the width of the CIS 32 is exactly the same with that of the recess 31, and a correction slip 33 is adhered to a bottom face of the front end of the loading deck 30.

[0019] A First gear set 35 and a paired second gear set 36 are set by a bracket (not shown), and a motor 34 is implemented to drive the first gear set 35, then the second gear set 36. The teeth 35a, 36a of the first and the second gear set 35, 36 are engaged with a gear bar 37, 38 formed under two opposite lateral sides of the loading deck 30 respectively, which, the loading deck 30 is thereby driven to pass over the CIS sensor 32 to have a name card scanned when the motor 34 drives the first and the second gear set 35, 36.

[0020] In an schematic view of a third embodiment of this invention shown in FIG. 4, a recess 41 for loading a name card is formed in a loading deck 40 centrally and an adhesive plastic film (not shown) is laid on the recess 41 for eliminating image distortion in the event of a folded name card. The loading deck 40 is about 1 mm thick while the recess 41 is about 0.2 mm deep such that a name card is permitted to be attached as closely as possible to a contact image sensor (CIS) 42 having a view depth of 1 mm only. Moreover, the width of the CIS 42 is exactly the same with that of the recess 41, and a correction slip 43 is adhered to a bottom face of the front end of the loading deck 40.

[0021] A first gear set 45 set by a bracket (not shown) is engaged by taking advantage of its teeth 45a with a plurality of slots 47 formed on one side of the loading deck 40. When a motor 44 drives the first gear set 45, the loading deck 40 is driven to pass over the CIS sensor 42 to have a name card scanned. A wheel 46 located on another side opposite to the slots 47 runs along a rail 48 opened downward for supporting the loading deck 40.

[0022] In an schematic view of a fourth embodiment of this invention shown in FIG. 5, a recess 51 for loading a name card is formed in a loading deck 50 centrally and an adhesive plastic film (not shown) is laid on the recess 51 for eliminating image distortion in the event of a folded name card. The loading deck 50 is about 1 mm thick while the recess 51 is about 0.2 mm deep such that a name card is permitted to be attached as closely as possible to a contact image sensor (CIS) 52 having a view depth of 1 mm only. Moreover, the width of the CIS 52 is exactly the same with that of the recess 51, and a correction slip 53 is adhered to a bottom face of the front end of the loading deck 50.

[0023] A first gear set 55 set by a bracket (not shown) is engaged by taking advantage of its teeth 55a with a gear bar 57 formed below one side of the loading deck 50. When a motor 54 drives the first gear set 55, the loading deck 50 is driven to pass over the CIS sensor 52 to have a name card scanned. A wheel 56 located on another side opposite to the gear bar 57 runs along a rail 58 opened downward for supporting the loading deck 50.

[0024] In FIG. 6—an exploded view of a fifth embodiment of this invention—a recess 61 for loading a name card is formed in a loading deck 60 centrally and an adhesive plastic film (not shown) is laid on the recess 61 for eliminating image distortion in the event of a folded name card. The loading deck 60 is about 1 mm thick while the recess 61 is about 0.2 mm deep such that a name card is permitted to be attached as closely as possible to a contact image sensor (CIS) 62 having a view depth of 1 mm only. Moreover, the width of the CIS 62 is exactly the same with that of the recess 61, and a correction slip 63 is adhered to a bottom face of the front end of the loading deck 60.

[0025] A first and a second bevel gear set 65, 66 are set by a bracket (not shown). A motor 64 is provided to drive the first and the second bevel gear set 65, 66 by taking advantage of a stud 69. The teeth 65a, 66a of respective bevel gear sets 65, 66 are engaged with a bevel gear bar 67, 68 positioned under each side of the loading deck 60 so that the motor 64 drives the first and the second bevel gear set 65, 66 to have the loading deck 60 driven to pass over the CIS 62 and have a name card scanned.
