    摘要: A first reading guide includes a first guide member, which can turn around a first shaft and is so positioned as to face a first side of a document. The second reading guide includes a second guide member, which can turn around a second shaft and is so positioned as to face a second side of a document. The distance between a first reading position and a reference position is equal to that between a second reading position and the reference position. The first shaft is positioned on the side of the reference position where the first reading position is set. The second shaft is positioned on the side of the reference position where the second reading position is set.

    摘要: A magnetic head driving piezoelectric ceramic actuator having an actuator body and a coating layer. The actuator body has a piezoelectric ceramic substrate and first and second electrodes. The piezoelectric ceramic substrate has first and second principal surfaces, first and second side surfaces, and first and second edge surfaces. The first electrode has a first external electrode portion formed on a part of the first principal surface, and a second external electrode portion formed on the first edge surface. The second electrode has a third external electrode portion formed on the second edge surface, and a fourth external electrode portion formed on the first principal surface. Each of: at least a part of each of the first and second external electrode portions; and at least a part of each of the third and fourth external electrode portions, constitutes a joined portion mounted on the substrate by an electrically-conductive agent. The coating film covers at least a part of a surface of a portion of the actuator body other than the joined portions.
