1. A noise reduction unit comprising:
- a plurality of resistors arranged in parallel in a line connected to a device that is charged and discharged, wherein the plurality of resistors have different resistance values; and
a resistor switch that switches between the plurality of resistors such that when the resistor switch is connected to a first resistor of the plurality of resistors, no current flows through a second resistor of the plurality of resistors, and when the resistor switch is connected to the second resistor of the plurality of resistors, no current flows through the first resistor of the plurality of resistors, whereinwhen the device is discharged, the resistor switch first connects the first resistor of the plurality of resistors to the device and then connects the second resistor of the plurality of resistors to the device, andthe first resistor has a resistance value that is larger than that of the second resistor.

Abstract
A noise reduction unit includes a plurality of resistors arranged in parallel in a line connected to a device that is charged and discharged and having different resistance values. The noise reduction unit further includes a resistor switch that switches a resistor connected to the device between the plurality of resistors. When the device is discharged, the resistor switch first connects a first one of the plurality of resistors to the device and then connects a second one of the plurality of resistors to the device. The first resistor has a larger resistance value than the second resistor.
