## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved IC card device and the card ejection unit thereof; and more particularly to a card ejection unit applied in a data reader.
2. Description of Related Art
The information era has come to lead people living with technology and fashion. Along with the gradually popular related information devices, the electronic card storage device has gradually replaced the conventional identification card and cash, for example, ID card and bills. The identification IC card is being widely used in various public services, for example, the ID card or insurance with IC. People usually use such electronic card storage device for various types of trade related matters in our daily lives, for instance, using credit card for purchasing merchandises, and using ATM card to transfer or withdraw money. Such electronic card storage device has IC or magnetic strip for storing information, and to read out the information therein when being inserted into a corresponding reading device. Furthermore, the electronic card inserted in the reading device needs an ejection mechanism to release electronic card from the reading device effectively.
The conventional card ejection device mostly has a plurality of gears to eject the card by the mutual cooperation between those gears. However, such card ejector takes a larger space and usually applied in the larger machines, for example, the ATM. Because the electronic cards are popularly used for reading information, public transportation and electronic merchandising, and therefore the size of such device is preferably desired to be minimized to enable the user to carry for convenient usage. Accordingly, the miniaturized card ejector is required for satisfying the above need.
A conventional card ejector has a plurality of gears and a motor disposed at the entrance/exit of the electronic card and uses an electronic loop for controlling the gears and the motor to release the card. However, the design of the conventional card ejector is complicated, and the gears and the motor occupy larger space and cannot meet the need of the miniaturized size.
Another conventional card ejector applied in the IC card reader has a motor, which is used to drive a plurality of connected bars and release the bouncing element connected to a spring to eject the IC card. Even though this card ejection mechanism has the advantages of being light, thin, shorter and smaller, the motor directly pushes the horizontal bar. Although the horizontal bar is buckled to the vertical elastic element, but the horizontal bar is an L shape element and is directly connected to the motor, and therefore it is difficult for the motor to push the bar. Thus, the motor has to directly deal with extra resistance exerted by the horizontal bar.
Accordingly, the above short comings of the convention card ejectors neither fits the requirement of miniaturization nor a proper design for ejecting the card, and therefore still a lot of improvements are needed.
SUMMARY OF THE INVENTION
The present invention provides an simple design for IC card device and a card ejector, which is easy to operate and has the advantages of being light, thin, short and small so as to meet the requirement of the market.
According to an embodiment of the present invention, the IC card ejector comprises a base, a reading unit and a card ejection unit. The base comprises a positioning member and a horizontal slide track adjacent to the positioning member. The horizontal slide track is a slide track for the horizontal buckle; and a side of the horizontal slide track provides a support to the horizontal buckle while buckling to the vertical elastic element. The base comprises a vertical slide track on a side as the slide track for the vertical elastic element. The base comprises a reading portion at a central region of a reading unit, and a soft circuit is positioned adjacent to the reading portion. The soft circuit comprises a distal end connected to the reading portion, and a primal end connected to a calculation portion. The card ejection unit comprises a motor, a rotation bar, a horizontal buckle and a vertical elastic unit. A rotation bar is positioned corresponding to the motor whose center is movably connected to the base. A distal end of the rotation bar is supported against a distal end of the motor, and a primal end of the rotation bar is supported against a distal end of the horizontal buckle. The horizontal buckle is able to slide in the sliding horizontal track of the base. The horizontal buckle comprises a distal end buckled so as to connect to the vertical elastic element. The horizontal buckle comprises a side supported against a side of the horizontal slide track of the base for providing a stable support to the vertical elastic element. The horizontal buckle comprises a primal end supported at a first spring. The vertical elastic element comprises a buckle portion, a slide block, a card push portion and a second spring. The slide block is fixedly positioned beneath the vertical elastic element and is able to slide in the vertical slide track of the base. The vertical elastic element comprises a buckle portion as a side, and a second spring positioned parallel at another side. The second spring comprises a distal end supported against a side of the vertical elastic element and a primal end supported against a stop. The buckle portion can buckle to the buckle portion of the horizontal buckle. The flange of the buckle portion can slide on the sliding surface of the horizontal buckle. The card push portion is positioned adjacent to the buckle portion for ejecting the IC card.
From the above description, the IC card device and the card ejector unit thereof of the present invention is lighter, thinner, shorter and smaller compared to the conventional art, and the motivation method of the card ejector unit thereof includes a rotation bar between the motor and the horizontal buckle. Thus, the direction of the force exerted by the motor is changed after passing by the rotation bar and directly passes the force onto the horizontal buckle so as to avoid the extra resistance from the horizontal buckle. Accordingly, the motor can be more efficiently applied. Besides, the horizontal buckle comprises a side positioned tightly against a side of the horizontal slide track of the base and thereby buckles the vertical elastic element to prevent any accidental ejection of the IC card.
