[embodiment]
About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to a graphic preferred embodiment, can clearly present.
In order to solve hand-held electronic equipment in the past the problem of interim power shortage and the memory card that is difficult to read different-format is arranged easily, the expanding device of hand-held electronic equipment of the present invention can be electrically connected to hand-held electronic equipment in good time, with reader device and the standby power supply as hand-held electronic equipment.In following examples, as Fig. 1, the hand-held electronic equipment of expanding device collocation of the present invention is that example illustrates with PDA (Personal Digital Assistant) 1, yet have the knack of this skill person when knowing, also can be applicable to the hand-held electronic equipment of other kind, for example mobile phone, digital camera, digital camera or the like are not limited to the revealer of present embodiment institute.
Consult Fig. 1 and Fig. 2, the expanding device 2 of hand-held electronic equipment of the present invention uses for a PDA (Personal Digital Assistant) 1.This PDA (Personal Digital Assistant) 1 roughly has a housing 10, a display 11, an input block 12 and first transmit port 13 for external expanding device 2.Have the knack of this skill person when knowing that PDA (Personal Digital Assistant) 1 has more the basic equipment of PDA (Personal Digital Assistant) 1, for example Storage Media, battery, microprocessor or the like are not limited to present embodiment and disclose.In addition, in order to use expanding device 2, have the driver of expanding device 2 in this routine PDA (Personal Digital Assistant) 1.
This routine expanding device 2 comprises one second transmit port 21, a rechargeable battery 22, a memory card groups of slots 23 and a controller 24.The specification of second transmit port 21 conforms to first transmit port 13, to electrically connect first transmit port 13 separably.The specification of first, second transmit port 13,21 of this example be universal serial bus (Universal Serial Bus, USB).PDA (Personal Digital Assistant) 1 is given in electric power that 2 work of rechargeable battery 22 supply expanding devices are required and 24 controls of controlled device supply electric power in good time.Memory card groups of slots 23 usefulness are at least a memory card of planting.Use for convenient, the memory card groups of slots 23 of present embodiment has one first slot 231, for planting such as Compact Flash card Type I/II, the CF card of MicroDevice card and so on, one second slot 232, for plant SM card, one the 3rd slot 233, for planting such as Memory Stick card, Memory Stick Pro card, Memory Stick Duocard, the MS card of Memory Stick Duo Pro card and so on, one the 4th slot 234, for planting such as Secure Digital card, the SD card of Mini SD card and so on, and one the 5th slot 235, for planting such as Multi-Media card, the mmc card of Multi-Media card second generation and so on, cause memory card groups of slots 23 can be inserted to the memory card of multiple different size, and then convenient PDA (Personal Digital Assistant) 1 read and write data.In addition, have the knack of this skill person when knowing that the specification of first, second transmit port 13,21 can be adjusted according to design requirement, the slot specification and the quantity that reach 23 settings of memory card groups of slots also can be adjusted according to design requirement, are not limited to present embodiment and disclose.
This csr controller 24 electrically connects second transmit port 21, rechargeable battery 22 and memory card groups of slots 23, to plan as a whole the overall operation of expanding device 2.When second transmit port 21 of expanding device 2 was plugged to PDA (Personal Digital Assistant) 1, controller 24 was subjected to PDA (Personal Digital Assistant) 1 control to give PDA (Personal Digital Assistant) 1 with the electric power of in good time supply rechargeable battery 22 or the memory card in memory card groups of slots 23 of reading and writing data.
Specifically, when the battery electric power of PDA (Personal Digital Assistant) 1 is not enough, PDA (Personal Digital Assistant) 1 can be by first, second transmit port 13,21 notification controllers 24, order about controller 24 with the electric power of rechargeable battery 22 through first, second transmit port 13,21 feed-in PDA (Personal Digital Assistant) 1, use or directly supply PDA (Personal Digital Assistant) 1 work required electric power for the battery charge of PDA (Personal Digital Assistant) 1.When the data in the PDA (Personal Digital Assistant) 1 desire reading and writing memory card, can earlier memory card be inserted in the slot corresponding in the memory card groups of slots 23, PDA (Personal Digital Assistant) 1 can read data in the memory card to PDA (Personal Digital Assistant) 1 by controller 24, also can will write from the data of PDA (Personal Digital Assistant) 1 in the memory card by controller 24, make the memory card of the erasable multiple different-format of PDA (Personal Digital Assistant), except that can making its data capacity increase, stored data when also playing or browsing the work of other kind hand-held electronic equipment at any time, for example captured photo of digital camera, image that digital camera is captured or the like.
Again, take PDA (Personal Digital Assistant) 1 limited transmit port (referring to first transmit port 13) and can't expand other function of use for fear of this routine expanding device 2, therefore the expanding device 2 of present embodiment more is provided with one the 3rd transmit port 25, electrically connects controller 24 and conforms to first transmit port 13 of PDA (Personal Digital Assistant) 1 with specification.Therefore, the specification of the 3rd transmit port 25 of this example also is a universal serial bus.So, other electronic equipment, for example carry-on dish, personal computer or the like, also can be electrically connected to PDA (Personal Digital Assistant) 1 by the 3rd transmit port 25, controller 24, second transmit port 21 and the 3rd transmit port 13, make PDA (Personal Digital Assistant) 1 also can use the function of other electronic equipment, and then reach effect more convenient to use.
Moreover, this routine expanding device 2 is provided with a power port 26 that is electrically connected to controller 24, so that extraneous power supply can be in power port 26 feed-in expanding devices 2, and controller 24 can be used extraneous electricity originally in good time to rechargeable battery 22 chargings, to reach convenient effect to expanding device 2 chargings.
According to preceding described, when the expanding device 2 of portable electric device of the present invention is electrically connected to portable electric device with second transmit port 21, portable electric device card-reading function and standby power supply can be provided, with memory card and the effective service time that prolongs portable electric device that makes things convenient for the user to read and write other form, to reach effect more convenient to use.
