PROBLEM TO BE SOLVED: To provide a sheet shutter device in which obstacle detecting sensors 16 are provided on right and left brackets 10, 11 while minimizing the right and left extension widths of guide rails.SOLUTION: Left and right brackets 10, 11 have upper and lower front pieces 10e, 10f, 11e, 11f, ceiling pieces 10b, 11b, and bottom pieces 10d, 11d bent and formed on body parts 10a, 11a to which winding drums 3 are journaled, outward in the horizontal directions, so that a front plate 12, a ceiling plate and a back plate 14, and a bottom plate 13 of a shutter case 2 are fixed thereto, respectively. Thus, spaces are secured outward in the horizontal directions of the bracket body parts 10a, 11a. Sensor mounting holes 10h, 11h are provided in the bracket body parts 10a, 11a so that the obstacle detecting sensors 16 are eccentrically mounted in the spaces, respectively. |
