Abstract: A differential signal is amplified by passive amplification which does not a reference of a common-mode voltage. At this time, the voltage of the differential signal is passive-amplified twice before carrying out a successive approximation type analog-digital conversion operation. The passive amplification is attained by providing a plurality of capacitances which carry out a sampling operation, and switching these connection relation by using switches. Without being accompanied by the increase of the consumed power and the chip size, an influence by the noise of s comparator is reduced to a half so that the effective resolution can be increased for one bit.

Abstract: An overhead scanner includes a main body, a rotation unit supported by the main body and being rotatable around a rotation axis, an imaging unit mounted on the rotation unit and is configured to read a medium placed on a placement surface below the rotation unit, a light source that irradiates the medium with light, a driving unit that moves the rotation unit around the rotation axis toward a placement side, where the medium is placed, and a posture change detecting unit that detects posture change of the main body.

Abstract: An image reading apparatus includes a lower unit, an upper unit arranged above the lower unit and a guide arranged on an opposite side to the lower unit with respect to the upper unit. The guide relatively rotates with respect to the upper unit in a direction away from the upper unit so as to form an ejection path, between the upper unit and the guide, of a sheet-like medium conveyed between the upper unit and the lower unit. The upper unit and the guide are close to each other respectively, at positions closest to the lower unit in respective rotation ranges of relative rotation with respect to the lower unit. The rotation range of the guide is wider than that of the upper unit, in a rotation direction away from the lower unit from the positions close to each other.
