For achieving the above object, a kind of peripheral contact type small electronic card provided by the invention, in order to be inserted in a reader device, this small electronic card mainly comprises:
One card body has a front end and dual-side, and this dual-side is mutual subtend and two proceeds posterolateral that lay respectively at this front end, and this card body is to insert this reader device by this front end;
A plurality of front edge contacts are along the front end of this card body and be provided with;
A plurality of extension contacts are provided with along this dual-side respectively, and wherein, each side has at least one extension contact.
Described peripheral contact type small electronic card, wherein, power supply, data, address and the control line of this front edge contact in order to standard to be provided.
Described peripheral contact type small electronic card, wherein, this extension contact is to improve the data transmission frequency range in order to expansion data transmission number of connections.
Described peripheral contact type small electronic card, wherein, this extension contact provides the data line of I/O function and extension.
Described peripheral contact type small electronic card, wherein, this front edge contact is the contact of SD card.
Described peripheral contact type small electronic card, wherein, this front edge contact is the contact of MS card.
Described peripheral contact type small electronic card, wherein, this front edge contact is the contact of mmc card.
Described peripheral contact type small electronic card, wherein, this each side has a plurality of extension contacts, and these a plurality of extension contacts are to be oblique interior the receipts to arrange.
Described peripheral contact type small electronic card, wherein, this reader device has a plurality of contact feets, and it is corresponding to the periphery of this card body and be provided with, to be in electrical contact with these a plurality of front edge contacts and a plurality of extension contact.
From the above, the present invention utilizes two side ends to extend contact, in the hope of frequency range and the transmission speed of expansion data transmission contact with the raising data transmission, and the setting of extending contact can not influence the design of reader device, more can avoid causing contact to repeat to touch to cause problem of short-circuit because of inserting or extract electronic cards.

Embodiment
One preferred embodiment of relevant peripheral contact type small electronic card of the present invention, please consult front elevation shown in Figure 5 earlier, in present embodiment, small electronic card 51 is the MS storage cards 41 that are compatible to as shown in Figure 4, as shown in Figure 5, it shows that this small electronic card 51 has a card body 52, this card body 52 has a front end 521 and dual- side 522 and 523, and dual- side 522 and 523 is mutual subtend and two proceeds posterolateral that lay respectively at front end 521, the upper surface of this small electronic card 51 is provided with a plurality of front edge contacts 58 and a plurality of side extends contact 59, wherein, aforementioned a plurality of side extends contact 59 and extends setting in correspondence with each other afterwards and along dual- side 522 and 523 for being arranged at front edge contact 58.
With aforementioned small electronic card 51, owing to have the setting that dual-side extends contact 59, therefore, this small electronic card 51 can provide enough contact numbers to promote the usefulness of electronic cards, in this embodiment, the front edge contact 58 of periphery contact type small electronic card 51 provides the power supply of standard, data, address and control line, for example, be same as the contact 411 of the standard MS storage card 41 of Fig. 4, and dual-side extends the data line that contact 59 provides extension, therefore, can be by significantly improve the material transmitting bandwidth by the increase of extending contact 59, to promote the data transmitting speed, in addition, contact 59 is extended at aforementioned two ends also can be as I/O is provided function, or other controlled function.
Fig. 6 shows that peripheral contact type small electronic card 51 of the present invention inserts in the schematic diagram of a reader device 65, wherein, be provided with a plurality of contact feets 66 in this reader device 65, its contact feet 66 corresponds to the periphery of this card body 52 and is provided with, and each contact feet 66 extends contact 59 in order to be in electrical contact with pairing small electronic card front edge contact 58 and dual-side respectively, therefore, when this small electronic card 51 was inserted in the reader device 65, the front edge contact 58 of small electronic card 51 and dual-side extended contact 59 and electrically contact with pairing contact feet 66 formation respectively.And because the front edge contact 58 of small electronic card 51 and extension contact 59 are the peripheries that are arranged at card body 52, therefore the contact feet 66 of reader device 65 is to arrange around the card body 52 of small electronic card 51, so do not have the crooked or design of configuration up and down of contact feet, therefore, the unlikely reader device 65 that causes is made the problem that is difficult for reaching the increasing of reader device 65 volumes.
The small electronic card 51 of present embodiment is one to have the specification compatible with MS storage card 41, and except that can being inserted in corresponding reader device 65, the MS card that more can be inserted in a standard is inserted poor.In addition, peripheral contact type small electronic card 51 of the present invention also can be designed to the specification compatible with other standard electric subcards, for example: mmc card, SD card etc.
Fig. 7 shows the peripheral contact type small electronic card 71 of another embodiment of the present invention, and they are different with last embodiment to be in a plurality of extension contacts 79 of these small electronic card 71 dual-sides is to present to receive in oblique to arrange.When this small electronic card 71 inserting reader device 85 or the process of extracting by reader device 85 in (please in the lump with reference to Fig. 8), because of extending contact 79, dual-side adopts oblique interior receipts formula arrangement, dual-side extends contact 79 and can not cause 86 moments of contact feet to touch because of being disposed at delegation, and causes short circuit.
The foregoing description only has been convenience explanation and giving an example, and the interest field that the present invention advocated is from should being as the criterion so that claim is described, but not only limits to the foregoing description.
