Abstract: PURPOSE: To automatically roll up and down a curtain, a hanging screen, etc., by a method wherein a string is wound on a bobbin with its free end in contact with a switch presser bar, the string is hung down by a desired length below a frame, and the end of the string is pulled up and fastened at an adequate position to form a U-shape slack in the string. CONSTITUTION: When a direct-current motor 2 spins in the forward direction, a bobbin 6 rotates, a string 7 falls down, and a hanging screen 16 that has been rolled up into a scroll-like shape is smoothly rolled down. When the roll-down operation of the hanging screen 16 finishes, the string 7 is slackened off because the length of a U-shape slack in the string 7 is a little longer than the hanging length of the hanging screen 16, and the contact of a first switch presser bar 9 or a switch presser bar 20 with a limit switch 10 is opened to stop the rotation of the direct-current motor 2. When the direct current motor 2 is reversed, the string 7 that is hung down is wound up on the bobbin 6 and the hanging screen 16 is gradually rolled up.  Then, a stationary ball 17 attached on the string 7 pushes up a movable ball 15 with a help of a spring 18, the movable ball 15 pushes up a lead string 14, the lead string 14 pushes up a second switch presser bar 12 or the switch presser bar 20 and an action piece of a limit switch 13 is pressed down, so that the rotation of the direct-current motor 2 is surely stopped and the hanging screen 16 is rolled up into a scroll-like shape.
