摘要： A capacitor (1) using a flexible substrate (2) includes a hole portion (6a) formed in a dielectric (6) to connect an upper electrode (7) to an external leader electrode (4). At least part of the hole portion (6a) extends from its lower end to upper end at an inclination between 0.1 and 20° with respect to a top surface of the external leader electrode (4). Then, an upper end corner of an inclined wall surface of the upper electrode (7), which inclines along the hole portion (6a) of the dielectric (6), has a downward inclination between 0.1 and 20°. A lower end corner of the inclined wall surface of the upper electrode (7), which inclines along the hole portion of the dielectric (6), has an upward inclination between 0.1 and 20°. As a result, stress concentration on the corners of the upper electrode (7) is drastically reduced to prevent the upper electrode (7) from cracking.

A stop member is fitted on one end of a wire and affixed to a rail. The wire is turned back via a driven pulley rotatably mounted on a half-speed carriage and then affixed to a full-speed carriage at a preselected point of the wire. Subsequently, the wire is again turned back by a driven pulley, and then turned back via a driven pulley rotatably mounted on the half-speed carriage. A stop member is fitted on the other end of the wire and temporarily affixed to the rail.

The automatic document feeder is provided with: a manuscript stacker adapted to have manuscripts stacked on it; an outer frame structure having the manuscript stacker movable to attain the open and shut states; and a handle section provided integrally with the outer frame structure and disposed anteriorly to the manuscript stacker. The space between the manuscript stacker and the platen cover serves as a manuscript discharging section. The handle section is formed in a shape so as to avoid narrowing the entrance for inserting a hand into the manuscript discharging section.
