DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable type apparatus for reading information recorded on an IC card.
2. Description of the Background Art
An apparatus shown in FIG. 4 has been known as a portable type IC card reader. This apparatus 60 is constructed so that a connector 70, which is formed as a separate unit from a housing, is built in the housing of the apparatus 60 and a connection terminal of the connector 70 is connected to an external terminal of the IC card 78 to enable reading of information stored on the IC card.
FIG. 5 shows a disassembled cross sectional view of the connector 70 before the IC card 78 is inserted. In FIG. 5, 71 is a connection terminal, 72 is a terminal holder, 73 is a groove, 74 is a frame, 75 is a spring, 76 is a rib and 77 is an inlet slit. The terminal holder 72 to which the connection terminal 71 is attached has the rib 76 which extends in a vertical direction at a side opposing to the inlet slip 77 and is energized towards the inlet slit 77 by the spring provided behind the rib 76. The terminal holder 72 is engaged with the groove 73 provided in the frame 74 and moved along the groove 73 in the frame 74.
FIG. 6 shows a cross sectional view of the connector 70 after the IC card 78 has been inserted. The connector 70 into which the IC card 78 has been inserted comes in a state that the rib 76 of the terminal holder 72 is kept in contact with the extreme end of the IC card 78. When the IC card 78 is further inserted inwardly from the above-described state, the terminal holder 72 is moved inwardly. In this case, the terminal holder 72 is moved down inwardly while being guided by the groove 73 provided on the frame 74. The terminal holder 72 is slantly moved as the IC card 78 is moved in a horizontal direction. The terminal holder 72 is moved as described above and to cause the connection terminal 71 of the terminal holder 72 to be connected with the external terminal of the IC card. When a power supply switch is turned on under this condition, the IC card reader 60 reads the information stored in the IC card 78.
However, the connector 70 has a complex construction including moving members and this complex mechanism of the connector 70 has resulted in malfunctioning and contact abnormality. The connector 70 has been formed as a unit separated from the housing for its complex mechanism. In other words, the IC card reader has been doubly structured by combining the connector 70 and the housing. Therefore, the IC card reader 60 has included a larger number of component parts, and has been extremely excessive in its construction and configuration and uneconomical in the man-hours and costs for manufacturing. In addition, it has been difficult to down-size the apparatus.
The present invention is intended to solve the above problems and implement the following points. by simplifying the mechanism of the connector. of the number of component parts by forming the connector as a unit which is integral with the housing for simplification of the construction of the apparatus. simplifying the mechanism of the connector and the configuration of the apparatus.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an IC card reader capable of solving the above-described problems. The IC card reader according to the present invention comprises a lower cover which forms a floor of an apparatus, an upper cover to be installed on the lower cover and a circuit board to be mounted on the upper cover.
The lower cover is formed with a bottom plate provided with a swingable part (depressing part) for pushing the IC card from the rear side.
The upper cover is formed with an insertion slit for the IC card, an insertion passage communicated with the insertion slit, a window opposing to the external terminal of the IC card to be inserted into the insertion passage, and a bottom plate provided With a swingable part (a card protection arm) for pushing the IC card, which is pushed from the rear surface side by the depressing par
