Description

図２は非接触のICカード１００とリーダ／ライター２の装置構成図である。図２において、リーダー／ライター２は総括的に示したリーダー／ライター制御回路５０によって、4.91MHzのクロック（電力供給用のキャリア信号でもある）と、PSK変調を行なってICカード１００へのデータ（下りデータ）を発生させ、コイル５１をドライブしてICカード１００側に電波(電磁波）で伝達する。一方、非接触式のICカード１００からリーダー／ライター２へのデータ（上りデータ）はコイル５１によって受信し復調再生を行なう。
また、ICカード１００は、コイル１０１によって、上記信号を受信し、電源回路１０２で直流電圧を発生させると同時に、送信受信制御回路１０３によって、下りデータの復調と上りデータの変調を行なう。復調された信号は、CPU１０４を介してメモリ１０５にデータを書き込む。前記メモリ１０５から読みだされた上りデータは、CPU１０４と送信受信制御回路１０３を介してコイル１０１をドライブする。
Figure 2 is a diagram of the device configuration of contactless IC card 100 and reader/writer 2. In Figure 2, reader/writer 2 uses a reader/writer control circuit 50, shown generally, to generate data (downstream data) for IC card 100 by performing PSK modulation with a 4.91 MHz clock (which is also a carrier signal for power supply), and drives coil 51 to transmit the data to IC card 100 by radio waves (electromagnetic waves). Meanwhile , data (upstream data) from contactless IC card 100 to reader/writer 2 is received by coil 51 and demodulated and reproduced .
Furthermore , IC card 100 receives the signal through coil 101 , generates a DC voltage in power supply circuit 102, and simultaneously demodulates the downstream data and modulates the upstream data through transmission/reception control circuit 103. The demodulated signal is written to memory 105 via CPU 104. The upstream data read from memory 105 drives coil 101 via CPU 104 and transmission/reception control circuit 103.

この分離した装置構成を図２３で説明する。図２３はリーダー／ライター２と、上位端末装置であるＰＣ（パーソナルコンピュータ）５００の構成を示したものであり、（ａ）図は、ノート型ＰＣ５００ａに採用したものを示し、（ｂ）図はテーブルトップ型ＰＣ５００ｂに採用したものを示している。
This separated device configuration will be explained with reference to Figure 23. Figure 23 shows the configuration of the reader/writer 2 and a PC (personal computer) 500, which is the upper terminal device, with Figure 23(a) showing the configuration adopted in a notebook PC 500a and Figure 23(b) showing the configuration adopted in a tabletop PC 500b.

また、（ｂ）図に示す装置構成では、リーダー／ライター２を、ヘッドユニット部６５を備えた本体１と、該本体１とコード１３を介して接続され、前記本体ユニット部６６を備えたボード５１０ｂとから構成し、該ボード５１０ｂをＰＣ用の増設ボードとして、テーブルトップ型ＰＣ５００ｂの拡張ボード挿入部に挿入する。この装置構成によれば、本体ユニット部６６をテーブルトップ型ＰＣ５００ｂの筐体内部に収納できるので設置スペースを小さくすることができる。
In the device configuration shown in Figure 1(b), the reader/writer 2 is composed of a main body 1 equipped with a head unit 65 and a board 510b equipped with the main body unit 66 and connected to the main body 1 via a cord 13, and the board 510b is inserted into an expansion board insertion portion of the tabletop PC 500b as an expansion board for a PC. With this device configuration, the main body unit 66 can be stored inside the housing of the tabletop PC 500b, thereby reducing the installation space.

また、図４に示すようにテーブル３の手前側は、両側にΘ１開いた裾広がりの形状としている。この裾広がり形状は、利用者がICカード１００をテーブル３に置き易くするためのものである。一般に、カウンター等にリーダー／ライターを設置した場合、人はテーブル３の延長線上から真っ直ぐにICカード１００をセットすることは少なく、右利きの人は右側に傾いて、左利きの人は左側に傾いた方向からICカード１００をセットする。特に、フレキシブルな構造を備えたICカード１００の場合は、 ICカード１００の先端部をテーブル３に正しく導くことが重要である。特に目の不自由な方には配慮しなければならない点でもある。そこでこの実施例では、右利き、左利きにも対応できるようにテーブル３の手前側は、両側に開いた裾広がりの形状としている。しかも、裾広がりの形状を構成するガイド部５は円弧状に形成され、かつ凸円弧状に連続しているので、スムーズにICカード１００をテーブル３の所定の位置に導くことができる。
As shown in FIG. 4 , the front side of the table 3 has a flared shape with a Θ1 opening on both sides. This flared shape makes it easier for users to place the IC card 100 on the table 3. Generally, when a reader/writer is installed on a counter or the like, people rarely place the IC card 100 in a straight line extending from the table 3. Instead, right-handed people place the IC card 100 tilted to the right, and left-handed people place the IC card 100 tilted to the left. In particular, for IC cards 100 with a flexible structure, it is important to guide the leading edge of the IC card 100 correctly onto the table 3. This is also a consideration that must be given to the visually impaired. Therefore, in this embodiment, the front side of the table 3 has a flared shape with both sides, so that it can be used by both right-handed and left-handed users. Furthermore, the guide portion 5 that forms the flared shape is formed in an arc shape and continues in a convex arc shape, allowing the IC card 100 to be smoothly guided to the desired position on the table 3.
