This invention offers a power supply circuit that is capable of improving a power factor as well as reducing a ripple current of an input/output of the power supply circuit due to switching of a switching device. The power supply circuit is provided with a first power supply circuit including first and second switching devices, a second power supply circuit including third and fourth switching devices and a switching control circuit. The switching control circuit controls the switching devices so that the first switching device and the third switching device are turned on and off at timings different from each other when an alternating current voltage from an alternating current power supply is positive, and the second switching device and the fourth switching device are turned on and off at timings different from each other when the alternating current voltage is negative.

An electrostatic discharge protection circuit has a bipolar transistor which includes a first diffusion layer of a first conductive type connected with a first power supply and functioning as a base; a second diffusion layer of a second conductive type connected with a second power supply and functioning as a collector; and a third diffusion layer of the second conductive type connected with an input/output pad and functioning as an emitter. An area of a first region of the third diffusion layer which is opposite to the first diffusion layer is larger than an area of a second region of the second diffusion layer which is opposite to the first diffusion layer.
摘要:
An LCD (21) for displaying a plurality of set information items is provided for a digital camera (10). When a plurality of input keys disposed around the LCD (21) are depressed, set information which is displayed adjacent to the input key can be changed. A control portion of the digital camera (10) performs a variety of control operations of the digital camera (10) in accordance with set information. Therefore, the position of the input portion which is used when the setting of the digital camera (10) can easily be understood. Thus, the setting can be changed by performing only a simple operation.
