An image reading device includes a conveyor unit that conveys a document along a conveying path for ADF-type image scanning including a curved path. The conveyor unit includes a conveyor roller that reverses a conveying direction of the document in the curved path. The device further includes a first contact surface that comes into contact with a first side of the document when the document is conveyed, a second contact surface that comes into contact with a second side of the document when the document is conveyed, a first reading unit that reads an image on the first side of the document, and a second reading unit disposed above the second contact surface and reading an image on the second side of the document. A part of the conveyor roller is disposed lower than the first and second contact surfaces in an up down direction of the image reading device.

The invention relates to a capacitor interface circuit. The capacitor interface circuit divides a capacitor to be measured into a variable part and an invariable part, designs a capacitance for neutralizing the capacitor to be same or similar to the fixed capacitance of the capacitor to be measured, and neutralizes the influence of the invariable part of the capacitor to be measured by utilizing charges which can neutralize the capacitor storage and has opposite polarity to the invariable part of the capacitor to be measured, thereby ensuring that a charger converter formed by a fully different amplifier and a feedback capacitor only reacts specific to the invariant part of the capacitor to be measured, and accordingly, increasing the precision of follow-up material processing.
