Abstract

PURPOSE:To reduce the cost of the titled device and to improve its operability by arranging connection terminals corresponding to respective external terminals on 1st and 2nd positions respectively corresponding to the arrangement positions of respective external terminals of two kinds of IC cards and arranging a connector part to be optionally moved so as to alternately position on each connection terminal on a substrate. CONSTITUTION:When the connector part 4 is moved in an arrow I direction and positioned on the 1st position P1 in case of an upper position type IC card, respective 1st contract points 6a of respective contract members 6 of the connector part 4 contract respective connection terminals 2a of the 1st position P1 on the substrate and are electrically connected. Since a spring part 4e is pressed against the hole edge part of a guide hole 3a, the connector part 4 is not blindly moved. When an upper position type IC card is mounted, respective external terminals C1-C8 of the IC card contact 2nd contact points 6b of respective contact members 6 and are electrically connected. Consequently, respective external terminals C1-C8 of the IC card are connected to respective connection terminals 2a on the 1st position P1 of the substrate 2 through respective contact members 6.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an IC card reader/writer used for reading, writing, and processing data on an IC card.

<Prior Art> Currently, two types of IC cards are recognized as international standards: an upper position type and a low position type, which differ in the arrangement positions of external terminals. To explain this with reference to FIG. 3, eight external terminals 01 to C8 arranged near the corners of the upper end 1a and left end 1b of the IC card 1 are of the upper position type adopted in France and other countries. In terms of things, A = 9.07 am+ and B = 16 from the top edge 1a of the IC card 1.
．． 69 mm and 7.62 mm between the two rows, while in the case of the low position type used in Japan, the United States, etc., C = 19.23 mm from the top edge 1a of the IC card 1. and D = 26.85
They are also arranged in two rows at a position of 7.62 mm between mm. Also, the position and arrangement pitch of the two rows are E = 10.25 mm and 17.87 m from the left end of the IC card 1.
It is 7.62 mm between m. In addition, each external terminal 01
~ In C8, C1 is a circuit voltage terminal, C2 is a reset signal terminal, C3 is a clock signal terminal, C4 is a spare terminal,
C5 is a zero voltage terminal, C6 is a program supply voltage terminal,
C7 is a data input/output terminal and C8 is a spare terminal.

<Problems to be Solved by the Invention> In this way, the external terminals C1 to C8 are arranged in different positions.
Because the types of IC cards 1 are recognized by standards, the locations of the connectors in IC card readers/writers are different, with the connection terminals located respectively to correspond to the external terminals 01 to C8 of each IC card. Two types of things are required.

In the future, it is expected that the low-position type will be standardized, but until then, two types of IC card readers/writers will be required, each with a dedicated connector for each position type.

Therefore, it is necessary to prepare two types of IC card readers/writers so that any type of IC card can be used, which is extremely wasteful and also requires a special reader/writer for each type of IC card. It becomes complicated because you have to select and load it. Also, I
The disadvantage is that the manufacturing cost of the C card reader/writer is also high.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an IC card reader/writer that is compatible with both upper position type and low position type IC cards.

Means for Solving the Problems> The present invention has the following technical means for achieving the above objects. That is, for two types of IC cards in which a predetermined number of external terminals are disposed at different positions, a predetermined number of external terminals are placed in the first and second locations corresponding to the respective locations of the external terminals. It is movably provided to be selectively located at the first and second locations with respect to the substrate on which the connection terminal is arranged, and each one end is connected to each of the locations at either the first or second location. A connector part having a predetermined number of contact members that are in electrically connected contact with the connecting terminals and each other end of which is exposed so as to be in electrically connected contact with each external terminal of the IC card. can be attached.

<Function> For example, if the first location and the second location on the board correspond to the respective external terminal locations of an upper position type IC card and a low position type IC card, then the upper position type IC card For the card, the IC card is loaded after the connector section is moved to the first location. Thereby, each external terminal of the IC card is connected to each connection terminal at the first location of the board via the contact member of the connector section, respectively. On the other hand, for a low-position type IC card, when the connector section is moved to the second location, each contact member of the connector section comes into contact with each connection terminal at the second location of the board and electrically Connected. In this state, the low position type I
When the C card is loaded, each external terminal of the IC card is connected to each connection terminal at the second location of the board via the contact member of the connector section. Therefore, it is possible to accommodate two types of IC cards, the upper position type and the low position type, simply by selectively moving the connector portion to the first location and the second location.

<Example> Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the main parts of the IC card reader/writer of the present invention, and FIG. 2 is a longitudinal sectional view of the main parts. In these figures, when an upper position type IC card is loaded on the board 2, eight connectors are connected to the first location P1 corresponding to the location U of each external terminal C1 to C8 of this IC card. Terminal 2a is arranged corresponding to each external terminal 01 to C8 of the Iq card, and when a low position type IC card is loaded, this IC
Eight connector connection terminals 2b are connected to the IC at a second location P2 corresponding to the location where each of the external terminals C1 to C8 of the card are provided.
They are arranged corresponding to each of the external terminals 01 to C8 of the card.

A base portion 3 whose upper surface serves as an IC card mounting surface is mounted and fixed on the substrate 2. A guide hole 3a is bored in this base portion 3 so as to face the above-described first location P1 and second location P2.

The connector portion 4 is inserted into the guide hole 3a at the first location P1.
and the second location P2 so as to be slidably inserted therein.

The connector portion 4 includes a slider body 5 having a substantially rectangular parallelepiped appearance and slidably fitted into a guide hole 3a, and two storage portions 5a and 5b formed parallel to the slider body 5.
It is composed of conductive contact members 6, in which a total of eight conductive contact members 6 are housed, four in each, and a bottom cover plate 7 that closes the lower openings of both the storage parts 5a and 5b, respectively. Each contact member 6 is bent into a dogleg shape and given elasticity, and has a first contact member formed at one end of each contact member 6.
A contact point 6a protrudes from the insertion hole 7a of the bottom cover plate 7 and comes into sliding contact with the substrate 2, and a second contact point 6b formed at the other end of each contact member 6 is connected to the slider body 5.
It protrudes from the insertion hole 4a. 8 of the aforementioned bottom cover plate 7
The insertion holes 7a are located at the first location P1 or the second location P.
2, each of the eight connection terminals 2a or 2b of the slider body 5 are arranged corresponding to the arrangement of the eight connection terminals 2a or 2b of
They are arranged corresponding to the arrangement of the eight external terminals 01 to C8 of the C card. Further, a position setting spring portion 4b is integrally formed on one side of the slider body 5 and is pressed against the hole edge of the guide hole 3a.

Next, to explain the operation of the above embodiment, for an upper position type IC card, when the connector part 4 is moved in the direction of arrow I in FIG. 1 and positioned at the first position P1, the connector part 4 The respective first contacts 6a of each of the contact members 6 of the four contacts contact the respective connection terminals 2a of the first location P1 of the substrate 2 and are electrically connected. At this time, since the spring part 4b is in pressure contact with the hole edge of the guide hole 3a, the connector part 4 does not move inadvertently. If you load an upper position type IC card in this state, the IC
Each external terminal 01 to c8 of the card corresponds to each contact member 6.
is electrically connected by contacting the second contact point 6b. As a result, each of the external terminals 01 to C8 of the IC card is connected to each connection terminal 2a of the first location P1 of the base Jfi2 via the contact member 6, respectively.

Also, for low position type IC cards,
