Description
Technical field
The present invention relates to the improvement to storage card (memory card) card reading system, and more specifically, relate to for the easy displacement of the receiver that is inserted into card reader and the memory card bridge of exchange, preventing that it is damaged, and the simple displacement of memory card bridge is provided and/or replaces to adapt to dissimilar memory cards.
Background technology
Storage card (sometimes being also referred to as memory card or data storage device) is more and more as the electronic storage medium in the various device.They are for the storage data with to other equipment transmission datas.These storage cards can read and write by card reader, and this card reader has receiver or the connector that is configured to the storage card compatibility of particular type.Card reader can be contained in digital camera, desktop computer, notebook computer, video camera, televisor and various Voice ﹠ Video player; In essence, it can be contained in that to utilize removable storage system to come the store compressed size be in any modern electronic equipment of preferred data.
There is very eurypalynous storage card on the Vehicles Collected from Market, the multimedia card (RS-MMC) that dwindles such as pcmcia card, compact flash (CF card), smart media card (SM card), memory stick (MS card), memory stick duo (MSduo card), minisize memory rod, multimedia card (MMC), size, miniature multimedia body card (miniature MMC), safe digital card (SD card), mini safe digital card (mini SD card), miniature secure digital card (miniature SD card), xD-graph card (xD card) etc.The following storage card that may develop other types.
Therefore, the card reader that needs number of different types, the card reader of each type is configured to read particular type or specific polytype storage card, because these storage cards of great majority are incompatible with other storage cards that have for the receiver (or input port) that receives one type storage card or storage card that may several type.These card reader can be inside or outside, and the two all only accepts one type storage card or the storage card of several types.Because these card reader are responsive electronic equipments, because user's excessive use or carelessness, they are easy to damage or become and can not operate.Because the small size of storage card, consider that these card reader often use with the portable set instrument, situation is particularly like this.These portable sets are at random placed usually, in use drop or are subject to other damages.
Because there is the storage card of number of different types, when the user uses storage card with data during from an equipment moving to another equipment, it is dimmed that the user may become.And the user is loading and is comprising in the correct card reader that is transmitted data storage Card Type compatibility and may have difficulties.In order to address this problem, a lot of card reader comprise some independently card reader as multisystem, accept and read (or writing) dissimilar storage card to use this card reader.
Under many circumstances, the personal user is partial to a kind of of individual storage demand or storage card that may two types.This user will only utilize one or two slot and corresponding connector (sometimes being called as receiver) in many card reading systems.Other slots and the connector of user's card reader will not be used or seldom be used.Therefore, reusing or wrong use procedure kind, only one or two connector of card reader wear, damage or unavailable, other connectors that kept system do not damage and can use.The user is forced to replace fully whole card reader, the number of the available unit that the imagination must abandon, this is unnecessary waste, if perhaps he is skilled in technique, he only removes and replaces the connector that the damage of card reader maybe can not operate, and this is to need suitable technical ability and the processing of time.Either method is all unsatisfactory.Can use easily and cheaply new connector to replace by unskilled people if damage the connector that maybe can not operate, then can save a large amount of time and fund.
In other cases, in the event of the card reader fault in the expensive electronic device that is embedded in such as digital camera, usually must replace whole camera, because the cost of repairing usually approaches or surpasses the cost of replacing.If the receiver of the card reader of digital camera (connector) can use the convenient and cheaply replacement of new connector, then the user buys new digital camera or carries out the money that expensive maintenance spends with regard to not needing to waste.
The card reader of these types also is embedded in very eurypalynous encouragement self-support user's the commercial operation post, such as being embedded in information kiosk etc.This can comprise automatic picture flushing booth, self-help bank, the booth etc. of paying the fees.Generally speaking, information kiosk itself is expensive, thereby because it comprises a lot of complexity and expensive electronic unit provides related service or product for the user.For maintenance with safeguard, they are not easy mobile and when they move, for the user serve or product unavailable.This from the income of above-mentioned information kiosk and when the client enters building with enterprise the client only find that disappointment two aspects that information kiosk is moved have adversely affected and use information kiosk to serve client's enterprise.The receiver that the damage of the card reader in the information kiosk maybe can not operate (connector) can cause can not operating of information kiosk, or the user with the storage card of the connector compatibility that can not operate can not be operated.If the damaged receiver (connector) of the card reader of information kiosk can make things convenient for and use new receiver (connector) to replace cheaply, these problems can be resolved.
In all these situations, the displacement of the receiver of the damage of card reader (connector) is must be by difficulty, the expensive and task consuming time of professional person's enforcement.
In having the typical memory card of a plurality of inputs, in card reader, input the type of slot predefine memory card for each.Because each receiver is fixed in the card reader, can not replace convenient and cheaply the input slot with one type memory card of the memory card compatibility of other types.This so that, for example, when the user buys when not having compatible receiver with the new electronic equipment of original incompatible memory card that uses and card reader, the user is difficult to change type that memory card receives device to change the memory card types that can use with specific card reader.In addition, the particular order that the user may wish to change the receiver of the compatible type in the card reader maybe can select to have a plurality of receivers with the card reader compatibility of same type, thus several memory cards of simultaneous adaptation same type.
Use traditional memory card reader, this is very difficult, thereby they have the fixed reception device of particular type, and does not dispose in the mode that solves the difference in every type the size of memory card.
According to prior art, if the buyer (for example wishes to use during fabrication 6 pre-configured card reader of slot, SD, CF, MS, SM, xD, MMC slot), manufacturer has manufacturing the card reader of a plurality of slots, these slots are installed in the desired location of surface-mounted integrated circuit in substantially permanent mode, and therefore changing will be difficult.Yet if the user wishes to have different card reader (for example, SD, MS, SM, CF, xD, MMC), manufacturer will redesign card reader so that these alternative installation sites to be provided.At this moment, the design cost that needs are higher and manufacturing cost.The embodiment of card reader of the present invention does not need to redesign by this way.If the order of slot needs to change, manufacturer can finish this point fast and cheaply by changing Ka Qiao.Only panel need to change according to the order of required slot.
And if occur the memory card of new type on the market, manufacturer can design new card reader easily to adapt to the memory card of this newtype.The card reader of prior art discussed above will need significant design cost and manufacture the new memory card types of original adaptation.And the real system that comprises in some cases, old card reader must be replaced.In this case, alternative costs will be very large.Yet the embodiment of card reader of the present invention only needs the change of Ka Qiao and panel so that card reader adapts to new memory card types.For example, if occurred the mini SD card of newtype on the market, card reader of the present invention only needs the newly-designed Ka Qiao that adapts to new mini SD card to work with the card reader one with existing invention, and the Design and manufacture cost of Ka Qiao is far below redesign and replace the cost of whole card reader.If card reader of the present invention purchased person use, the newly-designed memory card bridge that then adapts to the mini SD card of newtype will offer the user with in the available slot that is inserted into card reader of the present invention.The replacement panel can also be provided, and this replacement panel has the suitable slot for the mini SD card of this newtype.Do not need the replacement of whole card reading system to adapt to the memory card of this newtype, the variation of unique needs is changes of the interpolation of new Ka Qiao and displacement and possible panel.Significant cost savings when the result is fabrication phase and customer upgrade.
