ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a transmission device for card reader, more particularly, to a transmission device for a card reader, which has the advantages of compact size and broad applicability.
BACKGROUND OF THE INVENTION
There are more than one billion of recording cards in currency since the first card recorded with data appeared in 1920, and the recording cards are omnipresent in daily life. The categories of recording cards include ID cards for personal identification, cash cards for drawing cash, credit cards for purchase . . . etc. Beside the function aspect, the material, configuration, and recording/reading mechanism of those cards are different. For example, the recording card can be recorded with bossed letter, bar code, information stored in IC (IC card) or optical storage (optical card). Moreover, the security and degree of convenience of the card also depends on the material used and the recording/reading mechanism.
More particularly, the IC cards are provided with an IC chip for recording data (ISO 7816) and the terminal thereof is in static connection with a suitable connector. The applications of such IC cards include cash card, ID card . . . etc. The magnetic card is provided with a magnetic strip on one side thereof (ISO 7811) and the data stored in the magnetic strip is accessed by a dynamic magnetic head. The magnetic card can be accessed by part of the ATM machine. Another kind of magnetic card an all magnetic card, has a thinner structure and the data thereof can be recorded everywhere on the card. The all magnetic card can be, for example, a copy card, and has no particular specification. Besides, the transmission method of the card reader includes automatic type and a manual type. The automatic card reader has card transmission means for feeding or ejecting the card.
The transmission device of the conventional card reader includes a gear-transmission type and a belt-transmission type. As shown in
FIGS. 2 and 3
, the conventional gear-type transmission device comprises a motor (DC motor)
10
a
, a driving pulley
11
a
, a transmission pulley
12

and a driven pulley
13
a
. The motor
10
a
sends transmission power to the transmission pulley
12
a
through the deceleration of the driving pulley
11
a
. The driven pulley
13
a
is arranged below the transmission pulley
12
a
to clamp and move the card
14
a
. To minimize the constitutional parts of the device, the device employs single pulley arrangement.
As shown in
FIG. 3
, the conventional belt-type transmission device comprises a motor
15
a
, belt pulley set
16
a
,
17
a
, transmission pulley
18
a
, and driven pulley
19
a
. The motor
15
a
is decelerated by the driving pulley (not shown) and moves the belt-pulley set
17
a
and transmission pulley
18
a
through the belt-pulley set
16
a
, thus enabling the transmission pulley
18
a
and the driven pulley
19
a
to clamp and move the card
20
a
. The transmission device can move the whole card because the belt has a long-distance conveying ability.
The above-mentioned card transmission devices can convey a card in a steady, manner however, there are still some problem. The pulley-type card transmission device is only applicable to an all-magnetic card (thin card), and is not applicable to ISO 7811 magnetic cards. The belt-type card transmission device has a broader applicability, i.e., it can be used with ISO 7811 magnetic cards, and ISO 7816 IC cards. However, the conventional belt-type card transmission device has a bulky size and can not be applicable to all-magnetic cards (thinner card) because the thin card is liable to deform by the height difference among the transmission pulleys
18
a
. Moreover, the lifetime of the belt is limited.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide a card transmission device with broad applicability for use with ISO 7811 magnetic cards, ISO 7816 IC cards and all-magnetic cards, and having a compact size, and without the problem of a limited lifetime of a belt.
To achieve the above object, the present invention provides a card transmission device comprising a motor with a shaft connector, a worm shaft with worms on both ends thereof, two transmission shafts with one end engaging with a worm and another end having a transmission pulley, a driven pulley arranged below the transmission pulley, whereby the motor rotates the transmission shaft to enable the transmission pulley and the driven pulley to clamp and move the card.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
