Claims

[Claims for Utility Model Registration] 1. A set frame with a space that is fixed to a window frame, etc., a shaft support member provided at each end of the set frame, and a set frame rotatably supported at both ends by the shaft support members. A winding pipe, a screen attached to the winding pipe, a roll weight attached to the lower end side of the screen, an ultrasonic motor disposed in the space of the set frame, and a control device for controlling the operation of the ultrasonic motor. A drive gear driven by a sonic motor, a driven gear that meshes with the drive gear and rotates integrally with the winding pipe, and an interrupter that is disposed adjacent to the drive gear or the driven gear. have,
An electric roll screen in which a driving gear or a driven gear adjacent to which an interrupter is arranged is provided with a coding mechanism that allows the interrupter to read a coded signal according to the rotation of the driving gear or driven gear. 2. A screen bracket fixed to a window frame, etc., a winding pipe rotatably supported by the screen bracket, a screen attached to the winding pipe, a roll weight attached to the lower end of the screen, and a screen bracket. A motor bracket provided adjacent to the bracket, an ultrasonic motor attached to the motor bracket, a drive gear driven by the ultrasonic motor, and a motor bracket that meshes with the drive gear and rotates together with the winding pipe. a driven gear provided in the drive gear, and an interrupter disposed adjacent to the drive gear or the driven gear;
The driving gear or the driven gear with which the interrupter is arranged adjacent to the driving gear or the driven gear is provided with a coding mechanism that allows the interrupter to read a coded signal according to the rotation of the driving gear or driven gear. roll screen.
