The present invention relates to a frame-type signage device that can be utilized for various purposes as a wall-mount or stand type.

In general, a signboard is a cover written by using a name, a product name, or a business item to attract the attention of various people in a store, a company, or an institution.In recent years, a signboard is a general sign written on or in front of a store door due to the development of industry and civilization. In addition to the signboards of various forms, there are a variety of signs such as protruding signs, rooftop signs, signboards, advertising towers, neon signs, and billboards.

Most of the signboards including the recent enlarged signboards are generally provided with a light emitting device therein such that the display contents are visible to people at night as well as at night. Such light emitting devices are representative of electric light source devices such as fluorescent lamps and neon tubes. If such a light source device is installed inside a signboard container and a character, a picture, etc. is displayed on the surface of the signboard, the characters are displayed at a high luminance. Contrast difference can be obtained by day and night will be easy to recognize from afar.

1A and 1B are a perspective view and a side cross-sectional view showing an example of a conventional outdoor signage apparatus. Referring to FIG. 1A, the signboard 1 ′ installed in front of a store (bank) is composed of a front case 10 and a rear case 20 in which letters and pictures are largely formed. The front case 10 has a panel (P) made of a transparent or translucent material (for example, acrylic) is attached to the front surface and a coating film (F) for displaying a character or picture in a predetermined color thereon. Is attached, the rear case 20 is coupled to the rear of the front case 10 using a bolt or the like. Pedestal 30 serves to support the standing plate (1 ') consisting of the front case 10 and the rear case 20 to stand in balance.
