Power supply unit 10 is as power supply 20a～20n; Lithium battery for example is installed in power supply 20a, in power supply 20b, is installed under the situation of single 3 batteries, constitute circuit shown in Figure 2, each

power supply

20a, 20b are connected to the UNREG1 as other unit 30 connections of load via selection circuit 13a, the 13b of selection portion 13; On the power lead of the power supply 20a of lithium battery; At the downstream side of selecting circuit 13a, that is, selecting to connect discharge circuit 14 between circuit 13a and the UNREG1; On the power lead of the power supply 20b of single 3 batteries; At the upstream side of selecting circuit 13b, that is, between selection circuit 13b and power supply 20b, connect judging circuit 12 and the incorporate differentiation/discharge circuit of discharge circuit 11b.

Each selects

circuit

13a, 13b for example to have: in the future the small-signal that amplifies such as the control signal DCCTL-DIV of Self Control portion 16, DCCTL-T3 amplifies with transistor Q1a, Q1b (2SC4081 etc.); MOSFET (the field effect transistor: Field Effect Transistor) Q2a, Q2b that carries out conduction and cut-off and be connected/interdict with the power supply 20b of the power supply 20a of lithium battery and single 3 batteries respectively through the action of this transistor Q1a, Q1b; And by Fsb of soft start function portion that is connected in parallel the Fsa of soft start function portion that the resistor R a that realizes soft start function and capacitor Ca constitute with MOSFETQ2a, Q2b and constitutes by resistor R b and capacitor Cb etc.Through importing control signal DCCTL-DIV, DCCTL-T3 from control part 16 to transistor Q1a, Q1b; Thereby MOSFETQ2a, Q2b carry out connection/blocking that conduction and cut-off is carried out power lead; Simultaneously; When transistor Q2a, Q2B conducting, carry out soft start through the Fsa of soft start function portion that constitutes by resistor R a and capacitor Ca with by the Fsb of soft start function portion that resistor R b and capacitor Cb constitute.

This soft start function is following function: when selecting

circuit

13a, 13b conducting, apply the electric current restriction.

If realize remaining electric charge among the capacitor Ca, Cb of the Fsa of soft start function portion, the Fsb of this soft start function; Even then control part 16 outputs to pick-off signal and selects

circuit

13a, 13b;

Select circuit

13a, 13b to end, switch on, probably carry out wrong power supply and differentiate.Therefore, as back said, make the charge discharge of the Fsa of this soft start function portion, Fsb.

Have, the direction of the parasitic diode of this MOSFETQ2a, Q2b is with respect to be opposite direction from

power supply

20a, 20b to the UNREG1 direction as load again.

In addition, discharge circuit 14 has the transistor Q3 of small-signal amplification usefulness etc., and according to the discharge signal (BAT-DIS, BAT-TEST) from control part 16, the discharge of the electric charge of the later power lead of circuit 13a is selected in transistor Q3 conducting.

Judging circuit 12 for example uses epitaxial planar tranistor Q4, Q5; Begin to differentiate action through the test signal BAT-TEST from control part 16, differentiating the power supply that connects is the kind of the power supply of lithium battery or single 3 batteries etc., will differentiate the result to output to control part 16; Simultaneously; The signal BAT-KIND of expression power type is input to the transistor Q6 collector of discharge circuit 11b, and then, according to differentiating the base stage that the result is input to control signal discharge circuit 11b.

Discharge circuit 11b is according to the differentiation result of judging circuit 12 and conducting, carries out as list 3 batteries of power supply 20b and from the discharge of single 3 batteries to electric charge of the power lead of selecting circuit 13a.

Have, when for example single 3 batteries were installed in power supply 20b, signal BAT-KIND input high level (H) when discharge circuit 11b conducting, moved to low level (L) from high level (H), when single 3 batteries are not installed in power supply 20b, still remained high level (H) again.

Have again; Situation below having explained: power supply unit 10 is as shown in Figure 2; The discharge circuit that the power supply 20a side of lithium battery is installed is at the downstream side of selecting circuit 13a, that is, and and at the discharge circuit of selecting to connect between circuit 13a and the UNREG1 14; But the discharge circuit of power supply 20a side also can be as shown in Figure 3; Be the discharge circuit 11a that connects between power supply 20a and the selection circuit 13a, the structure of discharge circuit 11a self is identical with discharge circuit 14, carries out the discharge as list 3 batteries and single 3 batteries to the electric charge of the power lead of selecting circuit 13a of power supply 20b.

In addition, power supply unit 10 is not limited to Fig. 2 and that kind shown in Figure 3; Only connect discharge/judging circuit in the power supply 20b side that single 3 batteries are installed, for example, also can be as shown in Figure 4; Judging circuit 12 and the incorporate differentiation/discharge circuit of discharge circuit 11a are connected the upstream side of selecting circuit 13a, that is, select between circuit 13a and the power supply 20a; In addition, also can be connected the downstream side of selecting circuit 13a.This differentiation/discharge circuit 12 is same structure with the judging circuit 12 of the power supply 20b side that is connected Fig. 2 and Fig. 3, gives identical label, omits its explanation.In addition, discharge circuit 11a is same structure with the discharge circuit 11a of Fig. 3 also, omits its explanation.

And; Power supply unit 10, as selecting circuit 13a, 13b, adopting the parasitic diode of MOSFETQ2a, Q2b is opposite direction person with respect to each power supply 20a, 20b; But it is as shown in Figure 5; Also can adopt its parasitic diode is MOSFETQ12a, the Q12b of forward from power supply 20a, 20b to the UNREG1 direction of load, in the case, and with respect to the UNREG1 of load; Need select that the selection circuit 40 with MOSFETQ42 is set between circuit 13a, the 13b, this MOSFET42 is reciprocal parasitic diode with respect to load direction.This selects circuit 40, and selection circuit 13a, the 13b with other is identical basically, has: the small-signal of amplifications such as the control signal DCCTL-DIV of Self Control portion 16, DCCTL-T3 amplifies with transistor Q41 (2SC4081 etc.) in the future; Conduction and cut-off is carried out in action through this transistor Q41, the MOSFETQ42 that the output of selecting circuit 13a, 13b and UNREG1 as load-side are connected/interdict; And be connected in parallel with MOSFETQ2a, Q2b and realize resistor R c and capacitor Cc of soft start function etc.; Through the control signal DCCTL-DIV from control part 16, the DCCTL-T3 that is input to transistor Q41; MOSFETQ42 conduction and cut-off and carry out the connection/blocking of power lead; Simultaneously, when transistor Q42 conducting, carry out soft start through the Fsc of soft start function portion that constitutes by resistor R c and capacitor Cc.

The effect of explanation present embodiment below.Image recording structure 1 with power supply unit 10 of present embodiment can be at single 3 batteries of the last installation of the power supply 20a～20n of a plurality of kinds, lithium battery various power supplys such as (Li batteries); Which power supply in such power supply installed connected correctly differentiated; By selection portion 13, utilize soft start function, should be connected to load by connected power supply 20a～20n; And, wrongly also can guarantee safety even differentiate.

Have again, simple in order to make explanation in following explanation, as power supply, be made as power supply 20a with installation lithium battery and the power supply 20b that single 3 batteries are installed, describe.

Promptly; Power supply unit 10, as shown in Figure 6, if (insertion) lithium battery or single 3 batteries (step S101) are installed in power supply 20a or power supply 20b; Then control part 16 is with secondary CPU (SUB CPU) reset (step S102); The residual charge discharge that makes the Fsa of soft start function portion of the 13a of selection portion and select to accumulate among the Fsb of soft start function portion of circuit 13b simultaneously, continues to carry out the discharge (step S103) of the residual charge of power lead at discharge circuit 11a and discharge circuit 14 or discharge circuit 11a and discharge circuit 11b; Carry out read in (the step S104) of supply voltage simultaneously, read in the counting (step S105) in number of times or elapsed time.Have again, in following explanation, describe based on reading in number of times.

When reading in the counting of number of times; Control part 16 check is read in number of times whether below predefined stipulated number (setting) (step S106); When not reaching stipulated number, whether the check supply voltage is below predefined assigned voltage (setting) (step S107).

In step S107 not when setting is following; Control part 16 returns step S105 and begins to carry out above-mentioned same processing from the counting that reads in number of times, and check reads in whether number of times reaches setting or whether supply voltage reaches setting (step S105～S107), in step S106, read in number of times and reach setting; Perhaps supply voltage is that setting is when following in step S107; Control part 16 begins to differentiate the kind of power supply, that is, be lithium battery or single 3 batteries (step S108); Waiting for back of predefined stipulated time (setting) (step S109); Carry out read in (the step S110) of discriminant value, stop the differentiation (step S111) of supply voltage, whether the power supply that check is installed is single 3 batteries (step S112).

In step S112; When single 3 batteries had been installed,

circuit

13a, 13b, the selection circuit 13a conducting that will be connected with the power supply 20a that single 3 batteries have been installed were selected in control part 16 controls; Single 3 batteries are connected on other unit 30 as load, finish power supply control and treatment (step S113).

In addition; In step S112, when single 3 batteries were not mounted, control part 16 judged that lithium battery is mounted;

Circuit

13a, 13b are selected in control; The selection circuit 13b conducting that will be connected with the power supply 20b that lithium battery has been installed is connected to lithium battery on other unit 30 as load, finishes power supply control and treatment (step S114).

Have, in above-mentioned steps S106, even reading times has reached under the situation of setting, thereby the beginning power supply is differentiated the connection processing that moves on to power supply again; When residual charge does not discharge fully, or discharge circuit is inoperative, and testing circuit is inoperative; Certain inoperative etc. fault of judging circuit or selection portion perhaps takes place and residual charge when not understanding, or judging circuit is judged as when having connected a plurality of power supply; Because reading times reaches setting, can stop discharging action or detect action, move on to the connection processing of power supply; Carry out energising reliably, can work, improve usability power supply unit 10.

In addition; In the image recording structure 1 of the power supply unit with present embodiment 10; In the power supply control and treatment,, then also can be used as mistake and handle if the number of times that reads in of the supply voltage that reads in supply voltage before reducing to below the setting reaches stipulated number (setting).
