2. Description of the Related Art Guidance display devices provide people with information on evacuation routes, directions, etc. in the event of a fire or the like in various simple characters,
Disaster prevention lighting fixtures to be displayed on a display board in a drawing (eg, a picture of a running person), etc., and to be installed at key points in various public buildings so that they can be clearly seen from anywhere. Is a universal equipment among the legally required firefighting equipment.

[0003] Generally, a building is provided with a fire alarm system. The fire alarm system is configured to set several alert areas and collectively control fire sensors and guide lights installed in the areas.

Generally, a fire alarm system is configured as shown in FIG. When the fire sensor 30 detects a fire based on temperature or smoke, a fire signal is sent to the fire alarm receiver 31. The fire alarm receiver 31 sends a signal indicating the occurrence of a fire to the guidance light signal device 32. The guide light signaling device 32 sends a signal to all the guide lights 33 in the alarm area. Guide light 33
Performs flickering of the display board by this signal.

Conventionally, as a guide light 33, a display panel surrounded by a frame is provided on the front side of a box-shaped case, and a fluorescent lamp is provided at the center of the rear side of the display panel, and the entire display panel is illuminated with the fluorescent lamp. Such a configuration is generally widely adopted.

[0006] Recently, panel-type guide lights have been developed and are becoming popular. The panel-type guide light is manufactured by applying or sticking a light diffusion reflector on the back surface of a light-transmitting light guide plate, and draws a drawing for guidance on the surface of the display panel. This light guide plate is installed vertically, and light emitted from a light source installed directly above is projected from the upper surface of the display panel to the inside.

Light incident from the upper surface of the display panel travels downward in the display panel at various angles, is diffusely reflected by a light diffuse reflector provided on the back surface of the display panel, and exits through the surface of the display panel. go. At this time, the part of the drawing drawn on the surface of the display panel is shielded from light, so that it can be seen clearly.

However, the guide light has a required size and brightness at a position where the information about the evacuation route, direction, etc. can be transmitted to the people in an emergency such as a fire in a most reliable and effective manner. Need to be installed. Therefore, the installation position is not necessarily on the door frame, and it is instructed to install it in the most suitable position to indicate the evacuation direction. It is allowed to turn off.

[0010] On the other hand, the structure of the guide light itself and its display screen are not artistic at least, while buildings such as art museums and theaters that value the artistic atmosphere, while actively improving the disaster prevention function of the guide light. Within, it is important to consider harmony with aesthetics.

[0011] That is, like many tools in human life, it appears when it is desired to use it and performs its maximum function, but ideally it does not exist temporally and spatially when not in use.

The present invention has been made in view of the above point of view, and the present invention solves the problem of a guide light in which the display board does not appear outside except in an emergency, and appears only in an emergency to accurately indicate an evacuation direction. Have issues to be addressed.

[0013]

In order to solve the above-mentioned problems, a guidance display device according to the present invention draws a drawing for guidance on a front surface of a light-transmitting plate and cuts the drawing from an obliquely cut upper surface. A display panel configured to emit incident light from the front, and a display panel that is obliquely cut from the display panel .

The overall operation of the guidance display device having the above configuration is as follows. The guidance light signal device is used to provide a required guidance when a fire signal is received from a fire alarm receiver or when a signal notifying the end of projection or lecture is received from another fire alarm device such as a signal control device. Turn on the display panel fall signal for the light. In this case, an address is assigned to each guide light, and selective transmission is possible by including this address in the display panel overturn signal.

In each of the guide lights, the display panel 1 is held horizontally in the guide light body embedded in the ceiling unless the signal from the guide light signal device turning the display panel to itself turns on (FIG. 4). (B)).

In an emergency, for each of the guide lights addressed by the display panel fall signal, the display panel fall signal is turned on. As a result, the light source 3 is turned on at the same time as the display panel 1 falls as described above. That is, a bright display panel suddenly appears on the ceiling where nothing was seen before, and functions as a guide light (see FIG. 4B).

Hereinafter, as a second embodiment of the guidance display device according to the present invention, a display panel vertical drop type guidance display device will be described. In the present embodiment, the display panel 1, the latch mechanism 2, the light source 3,
