Description

  The present invention mainly relates to a display device for displaying an advertisement such as a poster.

  A conventional electroluminescent display device for displaying advertisements such as posters is such that a fluorescent lamp is disposed at the bottom of a case, and a display sheet fixed to the opening of the case with light from the fluorescent lamp is irradiated from the back side. It was.

  In such a conventional display device, since the fluorescent lamp is arranged inside the case in this way, the thickness of the case becomes considerable and the overall weight becomes considerable, and the installation place becomes a place of installation. There was a problem of being restricted.

  In addition, a transparent or translucent display sheet on which advertising characters or the like are displayed by printing is fixed to the opening of the case by being sandwiched by an adhesive, a double-sided adhesive tape, or a front frame. In the case of using an agent or a double-sided adhesive tape, it takes time to peel off the display sheet, and in the case of clamping by the front frame, the front frame must be removed by removing the screws one by one, which cannot be done quickly.

  For these reasons, there is a demand for the emergence of a light-emitting display device that is thin and lightweight, is not subject to installation location restrictions, and can be easily and quickly replaced, but has not yet been proposed. Nor is it found in the patent literature.

  The present invention has been made in view of the above points, and is thin, lightweight, free from restrictions on installation location, and can easily and quickly change display sheets. In addition, a fluorescent lamp is used as a conventional light source. It is an object of the present invention to provide a display device that consumes less power and has a longer lifetime than a display using the above.

  Thus, the gist of the present invention is that a plurality of LEDs fixed to the side portion of the case, a light guide plate that enters light generated from the LEDs from the side surface and is emitted upward by appropriate reflecting means, A transparent body having the same shape and the same size as the display body, in which a display body composed of a magnet attached to the peripheral edge of the upper opening of the case and a magnetic body adsorbed to the magnet in the display main body is disposed on the peripheral edge. The display device is characterized in that the display device includes a receiving sheet and a transparent or translucent display sheet sandwiched between the display body and the sandwiching sheet.

  In the above configuration, a plurality of LEDs may be arranged on a single board at a predetermined interval, and the board may be detachably attached to the side of the case. In such a case, when inconveniences such as non-light emission occur in some of the plurality of LEDs used as the light source, the substrate is removed from the case and only it is replaced, or all the LEDs have a lifetime. Thus, when the amount of light is halved, the substrate can be replaced with a new one, and the light source can be replaced easily. In addition, since only the light source needs to be replaced and other components can be used as they are, waste of discarding the whole can be avoided.

  In the above configuration, the display main body may be provided with appropriate wall surface setting means. In such a case, it can be stably installed on the wall surface.

  The present invention is configured as described above, and light generated from an LED as a light source fixed to the side portion of the case is incident on the light guide plate from the side surface, and the incident light is emitted to the upper portion of the light guide plate by appropriate reflecting means. Since the display sheet is irradiated, the display sheet can be configured to be much thinner and lighter than a display device in which a fluorescent lamp is disposed inside a conventional case. Therefore, the conventional display device can be installed in a place where it cannot be installed.

  In addition, the display sheet for printing advertisement characters and the like is sandwiched between the display body with a sandwich sheet that is attracted to the front opening of the display body by the attracting action by the magnetic force of the magnet. The display sheet can be replaced simply by turning the sheet. Therefore, the display sheet can be replaced much more easily and quickly than the conventional display device.

  In addition, since an LED is used as the light source, it consumes less power and has a longer life than a display using a fluorescent lamp as a conventional light source.

  In addition, when a plurality of LEDs are arranged at a predetermined interval on a single substrate and the substrate is detachably attached to the side of the case, a part of the plurality of LEDs used as the light source does not emit light. In the case of inconvenience such as, remove the board from the case and replace it alone, or when all the LEDs have halved the light amount due to their lifetime, the board can be replaced with a new one. It can be done easily. In addition, since only the light source needs to be replaced and other components can be used as they are, waste of discarding the whole can be avoided.

  In addition, when the display main body is provided with appropriate wall surface installation means, it can be stably installed on the wall surface.
