A recording-medium feeding device includes a container, a separating mechanism, and a suppressing member. The container accommodates recording media. The separating mechanism includes a driving member, a separating member, and a torque limiter. The driving member comes into contact with and delivers an uppermost recording medium. The separating member separates the recording media one-by-one. When a rotational torque smaller than a predetermined rotational torque is applied to the torque limiter, the torque limiter repels a load of the rotational torque to inhibit rotation of the separating member. When a rotational torque larger than or equal to the predetermined rotational torque is applied to the torque limiter, the torque limiter allows the separating member to be rotationally driven in accordance with the load. The suppressing member suppresses receding movement of the recording media caused by reverse rotation of the separating member when the driving member stops.

A driving method for a liquid crystal display device with a cholesteric liquid crystal having a memory mode of operation including a first stage of applying a first voltage to change the state of the cholesteric liquid crystal to a homeotropic state, a second stage of applying a second voltage to change the state of the cholesteric liquid crystal to a homogeneous state or a homogeneous/planar-mixed state, and a third stage of applying a third voltage to change the state of the cholesteric liquid crystal from the homogeneous state or the homogeneous/planar-mixed state to a focalconic state.

When a new image is written to a liquid crystal panel, row electrodes are scanned a-line-at-a-time in time periods T, T, selected row electrodes are set at a voltage V, and all column electrodes are set at &#x2212;V. The portions of a liquid crystal at the selected row electrodes have a voltage of V+Vapplied thereacross to bring the liquid crystal in the entire screen into a planar state. After the portions of the liquid crystal at all pixels have been brought into the planar state, new display is written by a-line-at-a-time scanning in time periods T, T.
