Below, to the effect of above-mentioned formation, with reference to Fig. 5 A, the program flow diagram of Fig. 5 B and Fig. 6, the sequential chart of Fig. 7 describes.
In Fig. 5 A, IC-card 5a, any one among the 5b is inserted in the card reader 4, and when providing the instruction ("Yes" of step S101) of reading beginning with keyboard 3, work is provided to (step S102) in the IC-card that has inserted with supply voltage VCC.So, provide the reset signal RST (step S103) that has only stipulated time t to become effectively (high level " H ") for the IC-card that has inserted, and its reset signal RST when being in effective status the 1st clock signal clk be provided.Then, the clock signal clk of 10KHz is provided (step S104).
According to this reset signal RST and clock signal clk, carry out data processing to synchronized model IC-card 5b.Like this, at each rising edge of clock signal clk, read data signal from the above-mentioned IC-card that has inserted, and the data of reading are extracted in each position repeatedly such as 3 times (odd number) (step S105).
Suppose that the IC-card that inserts is the synchronized model IC-card 5b that does not possess CPU, shown in the sequential chart among Fig. 7, be synchronized with the rising edge of the clock signal clk of 10KHz, the data among the synchronized model IC-card 5b are read with 1 bit serial.That is to say, be synchronized with the 1st rising edge 1 bit data a of clock signal clk, be synchronized with the 2nd rising edge 1 bit data b, the data that are synchronized with the data c of 1 of the 3rd rising edge are read out successively.Every data extract is regularly represented with arrow, like this for data a, b, c, d ... can carry out 3 times extracts.
Each three data that are extracted are compared, the data content that occupies the majority as benchmark, is determined above-mentioned sense data content to each position.That is to say that in 3 data, the data that number is many in " 1 " " 0 " are defined as valid data.(step S106).
Like this, because of getting 3 secondary data and come specified data in each position, so can prevent by misreading out that noise etc. causes.Also have, extraction time is not limited to 3 times, and 5 times or 7 inferior, as long as can tell most and minority just can suitably be set.The valid data that are determined are presented on the LCD 2.In the valid data of also have determining, repeat and with reference to these processes until obtaining stated number such as 10 positions (step S117, step S107), judge " 1 " that content is whether common then.(step S108).
Suppose the IC-card that inserted for not possessing the synchronized model IC-card 5b of CPU, carry out serial data output because of each 1, then 10 bit data are form appearance that arbitrarily mix with " 1 " and " 0 ".Can know the data that are provided with card in this state.
On the other hand, at Fig. 5 B, as other synchronized model, the sorting technique of non-synchronous type is for an example.Omit its explanation when other steps of Fig. 5 B are identical with Fig. 5 A.At step S118, judge whether the signal that receives from IC-card is (the International Organization for Stand) defined the ISO.That is, if be to be the signal of the initial output of synchronized model IC-card and to be the signal of regulation from the signal determining of IC-card output, determining device that then needn't dependency graph 5A can judge whether the IC-card of installation is (the step S118) of synchronized model.If the IC-card that has inserted is the non-synchronous type IC-card 5a that possesses CPU, data output can only be carried out according to external command input, and therefore the data of 10 positions are not original data but form that " 1 " occurs continuously.Therefore, when the content of 10 data was not " 1 " (NO of step S108) entirely, the IC-card that inserts in the card reader 4 was judged to be synchronized model IC-card 5b (step S109).If result of determination is synchronized model IC-card 5b like this, then continue to provide the clock signal clk (step S110) of 10KHz, provide the instruction of reading end of a period until keyboard 3 thereby continue that the data of synchronized model IC-card 5b are read processing.(step S111, S112).If 10 data contents are " 1 " (YES of step S108) entirely, the IC-card that then inserts in the card reader 4 is judged to be non-synchronous type IC-card 5a (step S113).At this moment, the clock signal clk that is provided is asynchronous with 3.5MHz (step S114) from switching to 10KHz synchronously.So, carry out time waiting (step S115) based on 40,000 clocks of the clock signal clk of 3.5MHz.Then, provide the usual effectively reset signal RST of (high level " H ").By judging behind the IC reception ATR, carry out the common processing (reading processing etc.) (step S116) of non-synchronous type IC then according to order here.The time waiting of 40,000 clocks be with the ISO specification specifies on non-synchronous type IC-card 5a.Data to this non-synchronous type IC-card 5a are read processing, only just produce data output with the operation input command of keyboard 3 time, and it is presented in the LCD 2.
Like this, automatically judge that the IC-card that is inserted in the card reader 4 is non-synchronous type IC-card 5a or synchronized model IC-card 5b, and be fit to the processing of reading of its result of determination automatically, thereby, has good versatility to any one can carry out data and reads processing among non-synchronous type IC-card 5a and the synchronized model IC-card 5b.Particularly, the synchronized model that begins when reset signal RST and clock signal clk at first are provided is read processing, carrying out card based on the sense data of this moment judges, read processing for the non-synchronous type that 40,000 clock times that need the ISO defined are waited for, can suitably carry out according to result of determination, therefore can be being used in the time of judging card, the time that perhaps obtains till the sense data was controlled in the extremely short time.Such time cripetura is quite easily for the user.Also have, the present invention does not limit to the foregoing description, and all distortion forms of implementation can be arranged in the scope that does not change aim.Such as, in an embodiment, mobile terminal device being illustrated, but also can being a following formula, it doesn't matter with the essence of inventing for this.
As mentioned above, set forth among the present invention and judged that the IC-card that inserts is non-synchronous communications protocol formula IC-card or synchronous communications protocol formula IC-card, and be fit to the card end device of reading processing of result of determination.Can provide like this asynchronous communication protocol formula IC-card and any good IC-card end device of versatility that can carry out data processing of synchronous communications protocol formula IC-card.Also have, in the invention of this IC, very at length illustrated and judged that the IC-card that inserts is non-synchronous communications protocol formula IC-card or synchronized model communication protocol formula IC-card and the process of reading processing that is fit to its result of determination with the control method of end device.Can provide like this control method of the good IC-card of any versatility that all can carry out data processing of asynchronous communication protocol formula IC-card and synchronous communications protocol formula IC-card with end device.
