Embodiment
The draw-in groove handover mechanism of the card reader that the utility model is a kind of, see also shown in Figure 1, mainly be provided with a card reader 1, this card reader 1 front end is provided with a plurality of for flash memory cards (as: CF card, SM card etc.) draw-in groove 11 of Cha Jieing, and the change-over switch 13 of these draw-in grooves 11 of cooperation, the rear end then is provided with a tandem bus-bar connectivity port 15 (USB Port), being connected with a computer by this connectivity port 15, see also shown in Figure 2 simultaneously, this card reader 1 also is provided with a microprocessor 16, these draw-in grooves 11, change-over switch 13, connectivity port 15 is connected with this microprocessor 16 respectively, when the user is plugged in a flash memory cards on the draw-in groove 11 of this card reader 1, changeable this change-over switch 13 is to position that should draw-in groove 11, the position that makes the microprocessor 16 of this card reader 1 be switched according to change-over switch 13, the draw-in groove 11 of selecting desire to link makes this storage card and card reader 1 interconnection line mutually, and can be in this storage card the access data.
In the utility model, see also again shown in Fig. 1,2, this card reader 1 front end is provided with the display 17 (as: light emitting diode (LED)) of a plurality of cooperation draw-in grooves 11, these displays 17 are connected with this microprocessor 16, when the user is plugged in flash memory cards on the draw-in groove 11, this microprocessor 16 can start display 17 that should draw-in groove 11, shows that with illumination mode this draw-in groove 11 has been plugged with flash memory cards.
In the utility model, see also again shown in Fig. 1,2, this card reader 1 can be one and has the card reader of two draw-in grooves 11, makes this card reader 1 can use CF Card and two kinds of flash memory cards of SM Card.This moment, no matter change-over switch 13 was cut to that draw-in groove 11, only a drawing out type disk drive can occur on the computer.Cut the draw-in groove to CF Card as change-over switch 13, then the flash memory cards that this drawer type disc driver linked is CF Card.Cut the draw-in groove to SM Card as change-over switch 13, then the flash memory cards that this drawer type disc driver linked is SM Card.Only a magnetic disc can appear to computer thus, the usage space that the user is still possessed two magnetic discs, and only use the built-in driver of operation system, do not need the puzzlement of other install driver.
In the utility model, see also Fig. 2, shown in 3, this change-over switch 13 is connected with the detecting pin position of microprocessor 16, be provided with a voltage source 30 (VCC) between this change-over switch 13 and the microprocessor 16, an and ground loop 31, on this voltage source 30 and be provided with a resistor 33, when the user with change-over switch 13 during to incision, the detecting pin position of this microprocessor 16 will be connected with ground loop 31, and detect an electronegative potential (Low), when the user upwards cuts change-over switch 13, to not be connected with ground loop 31, the detecting pin position of this microprocessor 16 will be connected with voltage source 30 via resistor 33, make voltage source 30 provide a magnitude of voltage to this detecting pin position, and detect a noble potential (High), so, electronegative potential (Low) is defined as a wherein draw-in groove 11, noble potential (High) then is defined as another draw-in groove 11, this microprocessor 16 can pass through the signal of electronegative potential (LOW) or noble potential (High), picks out the position that change-over switch 13 is switched.
In the utility model, see also shown in Fig. 2,4, when the user uses this card reader 1, this card reader 1 will be handled according to following step:
(401) the serial bar interface circuit of binding computer;
(402) do you judge that the detecting pin position that joins with change-over switch 13 is electronegative potential (LOW)? if continue the following step; Otherwise carry out step (406);
(403) set the draw-in groove 11 that is connected with computer and be draw-in groove 1;
(404) judge whether to desire the access flash storage card? if carry out the following step; Otherwise, proceed step (404);
(405) according to the position of change-over switch 13, the flash memory cards on the draw-in groove 11 that access sets, and then carry out step (404);
