ELECTRIC SHADING DEVICE

To provide an electric shading device capable of variably setting an upper limit position and a lower limit position at a desired position for each shading member when each of a plurality of stages of shading members connected in a vertical direction can be electrically raised/lowered, and an electric shading device for electrically controlling the raising/lowering of the shielding member by preventing a creep load.SOLUTION: An electric shading device according to an aspect of the present invention includes a control device 10 which makes it possible to electrically raise/lower each of a plurality of levels of shading members connected in the vertical direction, the plurality of levels of shielding materials including an upper shading member (upper screen 6U) and a lower shading member (lower screen 6L), and makes it possible to individually set respective upper limit positions or respective lower limit positions of the upper shading member and the lower shading member, or respective directions thereof within respective raising and lowering ranges. An electric shading device according to another aspect of the present invention includes a motor 9A capable of raising/lowering a shading member, and a control device 10 for controlling the drive of the motor 9A while monitoring an abnormal value related to the drive of the motor 9A.SELECTED DRAWING: Figure 1 【課題】上下方向に連ねた複数段の遮蔽材の各々を電動で昇降操作可能とする際に、それぞれの遮蔽材について、所望位置で上限位置、更には下限位置を可変設定可能とする電動遮蔽装置、並びにクリープ負荷を防止して遮蔽材を電動で昇降制御する電動遮蔽装置を提供する。【解決手段】本発明による一態様の電動遮蔽装置は、上下方向に連ねた複数段の遮蔽材の各々を電動で昇降操作可能とし、この複数段の遮蔽材が上部遮蔽材（上部スクリーン６Ｕ）及び下部遮蔽材（下部スクリーン６Ｌ）を有しており、上部遮蔽材及び下部遮蔽材の各上限位置、又は各下限位置、或いはその方向を、それぞれの昇降域の範囲内で個別に可変設定可能とする制御装置１０を備える。また、本発明による一態様の電動遮蔽装置は、遮蔽材を昇降可能とするモーター９Ａと、モーター９Ａの駆動に係る異常値を監視しながらモーター９Ａの駆動を制御する制御装置１０と、を備える。【選択図】図１
