The center of one side of the side plate and the integrally formed side plate is formed to communicate with the long hole formed in the circumferential axis and the square axis hole, the electric screen to form a bar-shaped bar cover at the bottom of one side of the side plate To provide a device.

In general, in classrooms and conference rooms of schools, light is projected on screens such as OHPs and projectors, and the contents are delivered by the audience.In the past, the use is various, so it is used in a ceiling or on a wall. It is used to distinguish between electric and manual.

Conventional electric screen devices are well known, such as Patent Publication No. 10-212091, Patent No. 10-443311 and Publication No. 10-2006-59029.

The "winding-up screen" of Patent No. 10-212091 is a rectangular case having an opening formed in the bottom and built in the longitudinal direction inside the case, one end of which is supported by a bearing, the other end is connected to the power mechanism A winding drum capable of developing and winding a screen, and a control unit on one side for driving the power unit, and a screen driving unit including an operation switch for operating the control unit, wherein the power unit is centered at one end of the guiding drum. And a driven member having a groove formed thereon, and having a worm and a worm gear rotated by a motor on one side thereof, and a driving member axially formed on the shaft of the worm gear, and then the projection of the driven member being a groove of the driven member. Coupled to the power transmission.

However, since the driving part is operated by the worm and the worm gear, the wound type screen easily wears gears due to long-term use, and because the size of the drum to be mounted inside is large, a case for storing the wound screen must be formed. There are disadvantages.

The “electric screen” of Korean Patent No. 10-443311 is a motorized screen device in which a roller bar with a screen wound therein is embedded and installed in a ceiling of an interior, and has a drawing hole to draw out a screen wound from the inside. Formed, but fixed to the desired point by the main body having a rail with a locking jaw in the upper side longitudinal direction and a support bolt inserted on the rail of the main body, the upper and lower ends of the 'c' shape bent However, the upper part is provided with a support member having a predetermined opening to form a support hole having an opening, and a bar-shaped hanger for engaging with the support hole formed on the upper side of the support member, which is fixed to the ceiling wall. It is composed.

However, the electric screen is inconvenient to be provided with a support bolt and a 'c' support member and a bar-shaped installation angle adjustment separately installed on the upper surface of the screen case in the process of embedding in the ceiling, installation time This takes a long time.

 Korean Patent Application Publication No. 10-2006-59029 “Assembly-embedded slide screen” is a motorized screen installed in a ceiling of a building by storing a roller bar in which a screen is wound inside. And a rectangular box-shaped screen box formed into a rectangular space fixed to the ceiling of the box bracket and fixed to the ceiling, and a screen fitted into the hem by being caught by an inner hook of the screen box and wound from the inside thereof. A box cap formed with a rotation fixing part for forming a drawing hole of the box cap and a box cap having a rotation fixing part for fixing both roller bars of the roll screen to one side in a rectangular shape to prevent both ends of the box cap and the screen box; It is fixed to the end of the fabric screen that comes down from the roller bar attached to the box cap to eliminate the bending of the fabric screen. Characterized in that the configuration including the lower circular bar.

However, the prefabricated embedded slide screen has a limited side surface that is used only because the rectangular box cap blocking both ends is fitted to the motor shaft inserted therein, and the bottom part is inserted into the inner side of the box bracket. There is a problem that the manufacturing cost is increased by using a combination of integrally formed by separating the fitting ring to be invisible.

The present invention is to provide an improved electric screen device to solve the above problems.
