摘要:
A power supply unit has a first power supply circuit that supplies a voltage to a load driving unit and a second power supply circuit that supplies a voltage to circuits other than the load driving unit. A first switching unit connects any one of a power supply that supplies a power supply voltage and a voltage step-down circuit that supplies a step-down voltage of the power supply voltage to the first power supply circuit. A second switching unit connects any one of the power supply and the voltage step-down circuit to the second power supply circuit. A control unit controls the connection by the first switching unit and the connection by the second switching unit to switch the voltage supplied to the first power supply circuit and the voltage supplied to the second power supply circuit in accordance with properties of the load driving unit.

摘要:
A display driving circuit drives common terminals connected to display components using a scanning signal of a predetermined period and drives segment terminals using a segment signal synchronized with the scanning signal, so that the display components perform a display corresponding to the display signal from the control circuit. The common terminals and the segment terminals are able to be independently driven. At this time, the common terminals are separated into a plurality of common terminal blocks and are driven and the number of separated common terminal blocks is variable.

A display device includes independently driven common and segment terminals. The common and segment terminals are connected to display components divided into display blocks that are turned ON to perform a display function and are turned OFF so as to not perform the display function. A first driver drives the common terminals using a scanning signal of a predetermined period and a second driver drives the segment terminals using a segment signal synchronized with the scanning signal to correspond to a display signal, so that the display components perform a display corresponding to the display signal. The first driver separates the common terminals into common terminal blocks and drives the common terminals. The first and second drivers perform the driving so that the common and segment terminals which are connected to display blocks that are turned OFF are not supplied with a turn-off signal and are maintained at ground potential.

To be able to measure a step number without carrying out an operation processing for selecting a walking sensor in a pedometer using a plurality of walking sensors having sensitivity axes different from each other. OR means converts walking signals inputted in parallel from walking detecting circuits into a synthesized walking signal. CPU calculates the step number by detecting the walking signal inputted to an input port. At this occasion, in detecting the walking signal, CPU alternately carries out a detecting operation of detecting the walking signal and a mask operation which does not detect walking at mask time immediately thereafter at each time of detecting each walking signal.
