Control circuit 30 is microcomputers etc., comprises operational part 31, ROM (ROM (read-only memory)) 32, RAM (random access memory) 33, RTC (real-time clock) 34 and motor drive circuit 35.Operational part 31 carries out various information processing according to the program be kept in ROM32.The reception data accepting the satellite-signal that circuit 20 receives are written to the buffer area in RAM33 successively, RTC34 supplies the clock signal used in the timing of radio-wave wristwatch 1 inside, the inside moment that operational part 31 is obtained by the signal timing supplied from RTC34 based on the satellite-signal received by receiving circuit 20 is revised, and determines the moment (display moment) that will be presented on moment display part 51 like this.In addition, motor drive circuit 35, according to the display moment of this decision, exports the drive singal of the motor driving driving mechanism 50 described later to comprise, thus, the display moment of being produced by control circuit 30 is presented at moment display part 51.
When control circuit 30 falls under voltage, in order to avoid unexpected action stops, in execution, the data in RAM33 are stored on the basis of the process of the necessity such as nonvolatile memory, temporarily stop action.The control being made by this control circuit 30 action of itself stop is called that Circuit Interrupt controls, and state control circuit 30 being controlled the radio-wave wristwatch 1 that action is stopped by Circuit Interrupt is called Circuit Interrupt state.Start-up circuit 36 breaks under state in circuit, time more than voltage resume to setting, the control signal of restarting of instruction control circuit 30 is input to control circuit 30, opportunity is input as with the control signal from this start-up circuit 36, control circuit 30 is restarted, and radio-wave wristwatch 1 returns to usual operating state from power interruption state.
Each portion's supply electric power in the radio-wave wristwatch 1 such as power feeding section 40 pairs of receiving circuits 20, control circuit 30, start-up circuit 36.Driving mechanism 50 comprises stepping motor and the train of the drive singal action that basis exports from above-mentioned motor drive circuit 35, is transmitted the rotation of stepping motor, pointer 52 is rotated by train.Moment display part 51 is made up of pointer 52 and dial plate 53, and pointer 52 comprises hour hands 52a, minute hand 52b and second hand 52c.Operating portion 60 is table hat.Action buttons etc., it accepts the operation of the user of radio-wave wristwatch 1, exports its content of operation to control circuit 30, and control circuit 30 performs various process according to the content of the operation input that operating portion 60 accepts.
As shown in Figure 3, power feeding section 40 comprises solar cell 41, secondary cell 42, illumination detection circuit 43 and switch S w1.Solar cell 41 is configured under dial plate 53, and it is by being irradiated to the outer light generating such as the sunshine of radio-wave wristwatch 1, and by generating electricity, the electric power obtained is supplied to secondary cell 42, the generated energy of solar cell 41 according to be irradiated to radio-wave wristwatch light illumination and become.Secondary cell 42 is connected in parallel via the switch S w1 be connected in series and solar cell 41, and solar cell 41 only carries out electric power supply when switch S w1 connects to secondary cell 42.Illumination detection circuit 43 detects the illumination being irradiated to the light of solar cell 41, illumination detection circuit 43 exports and represents whether illumination exceedes the signal of given threshold value, this threshold value according to circumstances switches to any one in the first illumination threshold and the second illumination threshold, and illumination detection circuit 43 also comprises the first resistor 44, second resistor 45, voltage stabilizer 46, comparer 47, switch S w2 and Sw3.
First resistor 44 and the second resistor 45 are the pull down resistors of the output voltage Vhd controlling solar cell 41, the resistance value of the first resistor is the resistance value R2 that R1 is greater than the second resistor, in addition, first resistor 44 is in parallel with solar cell 41 via the switch S w2 be connected in series, and the second resistor 45 is in parallel with solar cell 41 via the switch S w3 be connected in series.When switch S w2 connects, when switch S w3 disconnects, the first resistor 44 becomes contact resistance device, otherwise the second resistor 45 is contact resistance device.
Comparer 47 has two input terminal T1 and T2, and it is the comparator circuit exporting the signal representing the result after comparing the voltage swing being input to these two input terminals.Input terminal T1 is connected with the output of solar cell 41, and output voltage Vhd is input to input terminal T1.Input terminal T2 is connected with the output of voltage stabilizer 46, and threshold voltage vt h is input to input terminal T2.The output of comparer 47 is connected to control circuit 30 and start-up circuit 36.
As shown in Figure 4, realizing satellite signal receiving portion 31a, by receiving the satellite-signal sent from gps satellite, obtaining the data of the time information wherein comprised.The information that moment correction portion 31b utilizes satellite signal receiving portion 31a to receive from gps satellite, carries out the internal clocking in radio-wave wristwatch 1 and the correction in the inside moment obtained.Circuit Interrupt control part 31c is when the voltage of secondary cell 42 is below setting, and the power breakdown carrying out the pause in action making control circuit 30 controls.Restarting handling part 31d utilizes this voltage detecting circuit to measure the cell voltage of secondary cell 42 termly, when detecting that cell voltage is below setting, carries out power breakdown control.Restart process mend 31d under power interruption state from start-up circuit 36 receive start instruction time, perform control circuit 30 restart process.
As shown in Figure 5, under power interruption state, start-up circuit 36 waits for that the sampling instant of regulation arrives (S1), switch S w1 is switched to disconnection (S2), switch S w2 connects, and switch S w2 disconnects, and the contact resistance device of solar cell 41 is the first resistor 44, start-up circuit 36 confirms the output signal level (S3) of comparer 47, makes switch S w1 again get back to connection (S4).When the output signal confirmed in S3 is low level (S5: the situation of " N (no) "), the illumination in this moment is below the first illumination threshold, solar cell 41 generates electricity hardly, so S1 got back to by start-up circuit 36, waits for next sampling instant.On the other hand, when the output signal of comparer 47 is high level (S5: the situation of " Y (YES) "), start-up circuit 36 performs the startup control treatment (S6) of control circuit 30.By the process of S6, after control circuit 30 is restarted, the satellite signal receiving portion 31a of control circuit 30 carries out the sampling of illumination by predetermined time interval, namely satellite signal receiving portion 31a waits for that the sampling instant of regulation comes (S7) again, switch S w1 and Sw2 is switched to disconnection, switch S w3 is switched to connection, thus make the contact resistance device of solar cell 41 change to the second resistor 45 (S8), in this condition, satellite signal receiving portion 31a confirms the output signal level (S9) of comparer 47, switch S w1 and Sw2 is made to get back to connection afterwards, switch S w3 is made to get back to disconnection, thus make the contact resistance device of solar cell 41 change to the first resistor 44 (S10).When the output signal confirmed in S9 is high level (S11: the situation of " N "), the illumination in this moment is below the second illumination threshold, on the other hand, when the output signal of comparer 47 is high level (S11: the situation of " Y "), be estimated as radio-wave wristwatch 1 to be positioned at outside room, so satellite signal receiving portion 31a carries out environment reception (S12).
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
