The present invention provides a sensor device and an electronic apparatus each of which does not make malfunction derived from outside ambient light such as sunlight. In the sensor device, an ADC outputs, to one of two input terminals of a comparison circuit, second data which is a digital value ADCOUT corresponding to a current Iin−I1 being the result of subtraction from a current I1 from a current Iin and which is larger than a threshold Data_th.

Disclosed are an illuminance sensor which has a spectral-response characteristic approximate to the spectral luminous efficacy and which has a low circuit complexity, and a display device including the illuminance sensor. The illuminance sensor includes (i) a current output circuit which, with use of a bitstream signal of a first analog-digital conversion circuit for carrying out an analog-digital conversion with respect to a first current flowing through a first light receiving element, outputs a current corresponding to the first current and (ii) a second analog-digital conversion circuit which receives a third current obtained by subtracting a current from a second current flowing through a second light receiving element and which thus carries out an analog-digital conversion with respect to the third current.

An infrared remote control receiver 20a includes a carrier detection circuit 12a. The carrier detection circuit 12a includes: a comparator 6a for comparing an output signal from a BPF 5 with a threshold voltage Vth1 which is a noise detection level; a comparator 6c for comparing the output signal from the BPF 5 with a threshold voltage Vth3 larger than the threshold voltage Vth1, the threshold voltage Vth3 being a first carrier detection level; and a logic circuit 8 for (i) controlling, based on the output signal D1 from the comparator 6a, the gain of an amplifier 4 so that an output signal D1 from the comparator 6a is not output. An output signal D3 from the comparator 6c is output as a carrier. Thus, it is possible to restrain malfunctions attributed to disturbance light noise.

A comparing circuit of the present invention includes: a charging and discharging circuit to charge a capacitor with charging current and discharge the capacitor with discharging current alternately in response to a switch of an input pulse signal; a comparator circuit to compare a capacitor-voltage (Csig) of the capacitor with a first threshold voltage (Vth1) and the capacitor-voltage (Csig) with a second threshold voltage (Vth2), which is higher than the first threshold voltage, to generate a pulse signal responsive to a result of this comparison, and to supply an output-signal generating circuit with the pulse signal to switch a level of an output pulse-signal; and a logical operation circuit to adjust a value of the charging current and a value of the discharging current by generating a signal that is based on the pulse signal and is to adjust the value of the charging current and the value of the discharging current of the charging and discharging circuit and supplying the charging and discharging circuit with the signal thus generated. This configuration makes it possible for the comparing circuit to maintain capability of preventing errors, and at the same time, improve in capability of outputting a pulse having a same period as that of an input pulse having a short pause period.

An operator sets a distance from the page head of an alignment mark using a mark position setting switch mounted in a duplex printing system. A first printer forms the alignment mark in a position of the distance from the page head of a web, and reports position information about the alignment mark to a second printer. The alignment mark is detected by mark detection means of the second printer. Control means performs control of a web transport speed so that a phase between generation timing of a mark detection signal which the mark detection means generates by detecting the alignment mark and control timing calculated from alignment mark position data, alignment mark interval data and a web feed control signal generated at a preset period becomes constant.
