ABSTRACT:
The present invention relates to a parting surface structure of a bulletin device for indication or decoration in station yards, underground passages, buildings, exhibitions, etc. A fitting slot is formed in the inner peripheral edge of a parting surface body which constitutes the front face of a device frame, and a second parting surface portion having a desired parting surface width is fitted in the fitting slot. According to this construction, part of the parting portion can be replaced with a parting surface portion having a desired parting surface width according to a bulletin to be used in a manufacturing factory or at a site where the bulletin device is mounted. Thus, it is possible to make adjustment freely to a parting surface width suitable for a bulletin to be used.
