Embodiment
Please refer to Fig. 1, it is a kind of system of shared connecting interface and wherein scanner and the peripheral unit unified according to a preferred embodiment of the present invention.
In order to make scanner utilize a connecting interface to be connected use with different types of peripheral unit, just utilize the connecting interface of general alleged connectivity port as scanner, make it be connected use, must solve some problems and just can reach purpose of the present invention with peripheral unit as automatic paper feeder or the light shield used of scanning egative film.One of them is exactly: utilize same connecting interface to be connected use with different types of peripheral unit, must pick out peripheral unit and belong to which kind of device actually.
Please refer to Fig. 1 and Fig. 2, scanner 100 comprises scanner connecting interface 110, wherein at scanner connecting interface 110 a plurality of scanner transmission ends is arranged, and is numbered 112 to 130 respectively.Though at present embodiment is with the transmission ends number of 9 transmission ends as scanner connecting interface 110, but different transmission ends numbers can be arranged according to circumstances, wherein so-called transmission ends is exactly the pin (pin) on the connectivity port, is to be used to transmit different signals to peripheral unit.
And in peripheral unit 200, peripheral unit connecting interface 210 and logical circuit 240 are arranged then.Wherein, on the peripheral unit connecting interface 210, several peripheral unit transmission ends (being pin) are arranged also, be numbered 212 to 230 respectively, and same, also different transmission ends numbers can be arranged according to circumstances.
Above-mentioned mentioned scanner connecting interface 110 and peripheral unit connecting interface 210, all for existing each other, wherein the pin number of two connecting interfaces needs identical, and two connecting interfaces in conjunction with the time, pin is configured in position on the connecting interface also to be needed identically, and one of general normal theory just is female joint for male joint, one.
And in order to allow scanner 100 can tell the peripheral unit kind of connection, so scanner 100 can utilize several pins several parallel detecting signals of input continuously at the beginning earlier, after treating that several pins in the peripheral unit connecting interface 210 of peripheral unit 200 receive these parallel detecting signals, the parallel detecting signal of being carried by the 240 pairs of peripheral apparatus connection interfaces 210 of logical circuit that couple with peripheral unit connecting interface 210 carries out logical operation again, and the feedback serial signal group of computing gained is returned in peripheral unit connecting interface 210.
Afterwards, feedback serial signal group is delivered to scanner 100 via peripheral unit connecting interface 210 and scanner connecting interface 110, judges the kind that has that it's too late of the peripheral unit that connected as scanner 100.
Now lift an example method of scanner identification peripheral unit kind is described, and for explanation is easily understood, present embodiment is that example explains with two transmission ends 112 and 114 of scanner connecting interface 110 as sending the parallel detecting signal synchronously.As shown in Figure 2, transmission ends 112 and 114 is pin 1 shown in it and pin 2, also can be 1 because the parallel detecting signal that transmission ends is transmitted can be 0, so the permutation and combination of the parallel detecting signal that two transmission ends are exported is respectively (0,0), (0,1), (1,0), (1,1).Certainly, peripheral unit 200 also has two transmission ends as the usefulness that receives the parallel detecting signal, be respectively peripheral unit transmission ends 212 and 214, when peripheral unit transmission ends 212 and 214 receives this 4 groups of parallel detecting signals, then can utilize logical circuit 240 that this parallel detecting signal of several groups is responded, peripheral unit 200 as shown in Figure 1 is a simple device of carrying out on/off operation, and its logical circuit 240 promptly is the circuit of a ground connection, therefore no matter received parallel detecting signal combination why, the feedback serial signal group of being passed back all is 0, therefore promptly can to receive one group of feedback serial signal group be (0 to the transmission ends 116 in the scanner 100,0,0,0) signal, and scanner can be told this peripheral device and is peripheral unit listed among Fig. 21.
And why other peripheral unit can return different feedback serial signal groups according to the logical circuit of wherein configuration, makes scanner tell the kind of peripheral unit.But situation about also having is a scanner does not connect any peripheral unit, and scanner transmission ends 116 sends Application Specific Integrated Circuit (Application Specmed Integrated Circuit at this moment; Being called for short ASIC) 150 signal will be all to be 1 signal, because in the circuit that transmits, have a voltage that applies noble potential, scanner can be learnt has or not the connection peripheral unit actually.
After scanner is learnt its peripheral unit that connects kind that has that it's too late, in order to make scanner can utilize same connecting interface to be connected, so the transmission interface between scanner and the peripheral unit is needed with number transmission of minimum transmission ends date with different peripheral unit.Because similarly be that the pin count that is connected with main frame of printer is just many than the pin count that mouse is connected with main frame, that is because the signal that printer sends main frame to is more than the signal that mouse transmits, what therefore the pin in the connectivity port was relative will be more, so must get a preferable pin count, make mouse and printer all can utilize this connectivity port to be connected with main frame.
With respect to the mentioned scanner of the present invention and its peripheral unit also is reason so, because the peripheral equipment that scanner connected is equipped with simply as only needs to transmit the peripheral unit that signal is a controllable switch, also make the peripheral unit of its running just like the control signal of need transmission volume.
Simple peripheral unit as shown in Figure 1, it can be the light shield in order to the scanning egative film that a user buys in addition, promptly only need a scanner 100 transmit an enable signal be its ON/OFF of may command whether.Have in the system of scanner and peripheral unit at this, the scanner connecting interface that comprises, peripheral unit connecting interface and logical circuit are all to mention its annexation and function in above-mentioned.
But in peripheral unit 200, comprise a control device 250 in addition, be coupled to peripheral unit connecting interface 210, in order to receive the enable signal that peripheral unit connecting interface 110 is carried, wherein this enable signal is to be used for driving the signal that peripheral unit carries out the switch running.This control device 250 is transistors of a gauge tap, after its base stage (Base) receives the enable signal that the scanner transmission ends 124 of scanner 100 sent, can utilize collector (Collector) to open the light shield power supply.
If but the peripheral unit that scanner 100 is connected is a peripheral unit as shown in Figure 3, as automatic paper feeder, then the signal carried of scanner 100 just needs more transmission bring in the transmission signal, so for only making the peripheral unit of simple switch control, just have a lot of pins and need not use, so just propose a kind of unify the to share system of connecting interface and wherein scanner and peripheral unit in the present invention.
In scanner 100, include two patterns and be respectively detection mode 160 and mode of serial transmission 170.Wherein, detection mode 160 has several parallel detecting signals, and its purposes required signal promptly as during the above-mentioned kind that has that it's too late in order to the detecting peripheral unit does not add at this and to give unnecessary details.And mode of serial transmission 170 then comprises the parallel serial line unit 172 that changes, and is several parallel control conversion of signals to be become at least one group serial control signal group.The revolution of supposing the control automatic paper feeder need have 6 control signals, transmits the required pin count of signal in order to reduce in the present embodiment, so utilize the parallel serial line unit 172 of changeing to transfer parallel signal to serial signal, so can reduce required pin count.
But all must send a signal to peripheral unit 200 owing in scanner 100, have two group modes, therefore the multitask switch 180 that connects detection mode 160 and mode of serial transmission 170 is provided in scanner, in order to carry parallel detecting signal or serial control signal group, why connect peripheral unit when judging, then Ci Shi pattern is at detection mode 160, in order to carry the parallel detecting signal, if want the running of transfer control signal with the control peripheral unit, then mode switch is arrived mode of serial transmission 170, carry out the transmission of switched serial control signal group.
Scanner connecting interface 110 then is to connect multitask switch 180 and have a scanner transmission ends at least, in order to receive and to carry parallel detecting signal or serial control signal group.
And peripheral unit connecting interface 210 that comprises in peripheral unit 200 and logical circuit 240 have been mentioned in above-mentioned, do not add at this and give unnecessary details.But the transformation from serial to parallel device 280 in peripheral unit 200 then is to couple peripheral unit connecting interface 210, is reduced into the parallel control signal in order to the serial control signal group that peripheral unit connecting interface 210 is carried.Because in scanner 100, the parallel control signal encoding is become the serial control signal group, making does not need too many transmission to bring in transmission parallel control signal, but must be in peripheral unit 200 serial control signal be decoded into original parallel control signal, could control the running of peripheral unit 200, bright dark etc. as running, the fluorescent tube of motor.Signal in the serial control signal group that wherein is converted more comprises clock signal and gating signal (strobe signal) except serial data.
Peripheral unit 200 is except receiving the control signal that scanner 100 is transmitted, also can input signal to scanner 100, as via user operation and produce a plurality of parallel input signals to scanner 100, so as to notifying the user to import which signal and how this responds.
Please referring again to Fig. 3, more comprise in peripheral unit 200: input media 290 promptly is to be used for allowing the user operate and then produce a plurality of parallel input signals, inputs in the scanner 100 via peripheral unit connecting interface 210 and scanner connecting interface 110.Wherein, in this embodiment, the input signal that input media 290 inputs to scanner 100 is a parallel signal, is applicable under the less situation of transmission signals, because if once Chuan Shu parallel signal is too many, can make that transmission ends is not enough.
So under situation that may be too many in response to the parallel signal of user's transmission, so more comprise in the peripheral unit 200 in Fig. 4: the parallel serial line unit 300 that changes, couple input media 290, in order to convert the parallel input signal that input media produced at least one group of serial input signals group, input in the scanner 100 via peripheral unit connecting interface 210 and scanner connecting interface 110, so can reduce the use of transmission ends (being pin).
But relative just must comprise at scanner 100: transformation from serial to parallel device 190 is connected in scanner connecting interface 110, in order to the serial input signals group is reduced into the parallel input signal before being converted.
From the above, scanner connecting interface 110 among Fig. 3 and peripheral unit connecting interface 210, the connecting interface that belongs to serial, parallel coexistence, and scanner connecting interface 110 among Fig. 4 and peripheral unit connecting interface 210, then only only belong to interface connected in series, because under the less situation of the signal flow of user's input, can not need to convert parallel signal to serial signal, but under the more situation of the signal flow of user's input, then in order not make pin use number to increase, so need convert parallel signal to serial signal.
In addition, mentioned parallel commentaries on classics serial line unit 172 and transformation from serial to parallel device 190 in scanner in above-mentioned all is disposed at the processing unit of scanner 100---among the SIC.
Wherein, supposing all has 9 transmission ends in scanner connecting interface 110 and peripheral unit connecting interface 210, it can be divided into 1 power delivery end, 1 ground connection transmission ends, 3 transmission ends that are used for transmitting the serial control signal group, but owing to need to transmit earlier the parallel detecting signal, carry out the transmission of serial control signal group again, therefore these 3 transmission ends also can be used as the transmission ends that transmits the parallel detecting signal, 1 transmission ends that is used for receiving feedback serial signal group, and all the other 3 remaining transmission ends promptly can be used as the input signal that peripheral unit is delivered to scanner.
Please refer to Fig. 5, it is applicable to that for a kind of method of unifying to share connecting interface of a preferred embodiment of the present invention scanner utilizes the scanner connecting interface, makes scanner can connect the method for different classes of peripheral unit.
This method that can unify shared connecting interface comprises: step s500, import several parallel control signals continuously to peripheral unit via the scanner connecting interface, again in step step s502, the logical operation of the parallel control signal being done via peripheral unit, produce feedback serial signal group and be back to the scanner connecting interface, in step s504, scanner can be judged the peripheral unit kind that is connected with scanner according to the received feedback serial signal group of scanner connecting interface afterwards.
At first, scanner can be earlier in step s504, judged whether the connection peripheral unit, if do not have, then feeding back serial signal can be (1,1,1,1), the expression scanner does not connect any peripheral unit (step s506), if but judge to have under the situation that connects peripheral unit and judge that in step s508 the feedback serial signal is (0,0,0,0), the peripheral unit of then representing scanner and being connected is the simple mechanism that a kind of need carry out ON/OFF control, so scanner only need carry enable signal to peripheral unit to get final product (step s510), otherwise the peripheral unit that i.e. representative is connected is the complex appts that the many groups of needs control signal is controlled, so need elder generation in step s512, several parallel control conversion of signals is become at least one group serial control signal group, again in step s514, via the scanner connecting interface, the serial control signal group is inputed to peripheral unit, with the running of control peripheral unit.
Wherein, after the serial control signal group inputed to peripheral unit, peripheral unit also needed the serial control signal group is reduced into the parallel control signal.
Please refer to Fig. 6, it is for there being the situation of input signal in peripheral unit the user.Wherein working as the user imports in step s600, as pressing a button, then peripheral unit can produce several parallel input signals in step s602, if in step s603, the not use number of discovery transmission ends still can be born parallel input signals, then can be directly in step s604, the input signal that will walk abreast transfers to scanner via the scanner connecting interface, otherwise, then need in step s606, the input signal that will walk abreast converts the serial input signals group to, to reduce the use number of transmission ends, again in step s608, serial input signals is transferred in the scanner via the scanner connecting interface afterwards.
In sum, the invention has the advantages that the feedback serial signal group of utilizing peripheral unit to pass back learns the kind that has that it's too late of peripheral unit, and between scanner and the peripheral unit during in the transmission of making signal, convert parallel signal to serial signal where necessary, make it reduce the transmission ends of using, to reach the purpose that to unify to share connecting interface, no longer need connecting interface of a peripheral unit, to increase the compatibility of each peripheral unit and scanner, and can reduce the connecting interface manufacturing cost simultaneously, simplify the volume of scanner, make the user can select to meet the scanner peripheral unit of demand, needn't worry to cause incompatible problem because of the type difference.
