An operational amplifier connects to a midpoint between a plurality of serially connected battery cells constituting a secondary battery to provide a charging circuit for inhibiting a charge/discharge current from flowin to the midpoint and an input/output current from flowing from the midpoint to each battery cell. The charging circuit includes excess voltage detectors for detecting whether the voltage is an excess voltage, and a charging controller for determining an overcharge state of each battery cell on the basis of the voltages detected and controlling an ON/OFF of a charging switch. Voltage followers include an operational amplifier, NPN transistor, and the like, connected to a midpoint between a first battery cell and a second battery cell and a midpoint between the second battery cell and the third battery, respectively. The outputs of the voltage followers are configured as the grounds of the excess voltage detectors, respectively.

A media stripper for use with a pair of first and second, opposed rotary members includes a stripper finger and a rotation restriction mechanism. The stripper finger has an operational edge thereof disposed adjacent to the first rotary member to strip a recording medium from the first rotary member. The stripper finger is rotatable around a pivot axis parallel to a rotation axis of the first rotary member either in a first rotational direction in which the operational edge approaches the first rotary member, or in a second rotational direction in which the operational edge approaches the second rotary member, so as to establish an operational position thereof relative to the first rotary member. The rotation restriction mechanism is disposed for contact with the stripper finger to restrict rotation of the stripper finger in the second rotational direction upon establishment of the operational position of the stripper finger.
