A sheet feeding apparatus main body for containing sheets in the inside thereof includes: a first cover and a second cover which are openable and closable; and a detecting sensor for detecting an opening and closing of the first cover. The detecting sensor does not detect closing of the first cover when the first cover is closed in a state in which the second cover is opened and detects closing of the first cover when the first cover is closed in a state in which the second cover is closed.

In manufacturing of an organic electroluminescence (EL) display device, after first electrodes are formed on a substrate, insulating films are formed on the first electrodes except regions corresponding to light emitting portions. Spacers are formed on the insulating films, and overhanging portions are formed so as to overhang the spacers. Thus, element isolating structure portions for isolating organic EL elements are formed. Then, organic EL films, second electrodes, and protecting films are sequentially formed between the spacers. In the thus formed light emitting portions of the organic EL display device, the bending angle of a bending portion of a pattern of the element isolating structure portion is larger than 90°.

A vehicle having a man power driving system in which a driving force by man power is applied through a gear change mechanism to rotate a wheel, an a motor driving system in which the wheel is rotated by a driving force of a motor. The man power driving system is equipped with a torque detector for detecting a man power driving force so as to drive the motor according to a magnitude of the man power driving force detected by the turque detector. A particularly durable gear change mechanism is not required, and thus a common gear change mechanism for bicycle can be used, thereby simplifying construction.

In the driving circuit for a display apparatus according to the present invention, a charging circuit applies a voltage equal to or higher than the highest positive gradation voltage to each data line for a predetermined period of time before the start of a period for applying a positive gradation voltage. After that, a positive gradation voltage in accordance with data is applied to each data line. Then, a period for the applying a negative gradation voltage is started, when a negative gradation voltage in accordance with data is applied to each data line. Accordingly, after being charged with a voltage applied by the charging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or lower gradation voltage. Alternatively, a discharging circuit first applies a voltage equal to or lower than the lowest negative gradation voltage to each data line for a predetermined period of time before the start of a period for applying a negative gradation voltage. After that, a negative gradation voltage in accordance with data is applied to each data line. Then, a period for applying a positive gradation voltage is started, when a positive gradation voltage in accordance with data is applied to each data line. Accordingly, after being discharged with a voltage applied by the discharging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or higher gradation voltage.
