DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an IC card reader, and more specifically, to an IC card reader provided with a simple arrangement by which an IC card can be easily inserted to and withdrawn from the reader.
BACKGROUND ART
With the development of semiconductor technology the degree of memory integration has been increased, and thus an IC card now can be applied to a numerical control apparatus, a PC (programmable controller) and the like as an external memory. In practice, an IC card reader is used to read the IC card and write data thereto. In this process, the IC card is manually inserted into and withdrawn from a connector by hand or by using a fitting or the like provided at the connector.
An IC card reader applied to a numerical control apparatus and the like is often used in an adverse environment, such as in a metal processing factory and the like, and thus must be made airtight to protect electronic components such as semiconductors accommodated therein. Nevertheless, the conventional IC card reader must have an opening for use as an insertion port, and an IC card reader enabling an IC card to be inserted into and withdrawn from the reader while maintaining the interior thereof in an airtight condition is not known in the prior art. Although a non-contact type IC card has been disclosed in an attempt to solve this problem, the cost thereof is very high.
DISCLOSURE OF THE INVENTION
Taking the above into consideration, an object of the present invention is to provide an IC card reader provided with a simple arrangement by which an IC card can be easily inserted into and withdrawn from the reader.
To solve the above problem, in accordance with the present invention, there is provided an IC card reader for reading an IC card, or reading and writing an IC card, comprising a withdrawing member engaged with an edge of the IC card for withdrawing the IC card and an L-shaped member engaged with a projection of the withdrawing member for moving the IC card, the L-shaped member being rotatably mounted on a door of the IC card reader for withdrawing the IC card by opening the door.
As the door is opened, the withdrawing member for withdrawing the IC card is moved by the L-shaped member mounted on the door in such a manner that the IC card is withdrawn from the reader. Conversely, when the IC card is to be inserted into the reader, it is pushed therein by closing the door.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a cross sectional view of an embodiment of an IC card reader according to the present invention showing a door for the reader in an open position;
FIG. 2 is a cross sectional view of an embodiment of an IC card according to the present invention showing the door in a closed position; and
FIG. 3 is a partial plan view of the IC card reader when viewed along the line of the arrow A of FIG. 1.
BEST MODE OF CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to drawings.
FIG. 1 is a cross sectional view of an IC card reader according to the present invention, wherein 1 designates a housing of the IC card reader, and 2 designates a guide fixed to the housing 1 by members 3 and 4, for guiding the IC card.
In FIG. 1, 5 designates an IC card engaged with a withdrawing member 16 for withdrawing the IC card 5. The withdrawing member 16 is provided with a projection 6. Designated at 7 is a door, shown in the open state in FIG. 1. This door 7 is rotatable about a shaft 8 and is provided with an L-shaped member 9 rotatably attached to a shaft 10. The L-shaped member 9 is engaged with the projection 6 of the withdrawing member 16 through a hole defined at the upper portion of a member 11. Accordingly, when the door 7 is turned in a direction shown by an arrow C in FIG. 1, the IC card 5 is withdrawn in a direction shown by an arrow B in FIG. 1.
Further in FIG. 1, 12 designates an eject button and 13 designates a latch for fixing the door 7. The latch is arranged to turn about a shaft 14.
FIG. 2 shows the above embodiment of the inven
