Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device, and more particularly to an indoor fixed electric signboard display or a new and innovative signboard display variable type guidance display device.

Since then, there have been many indoor signboards. However, conventional indoor signboards have uniformly fixed displays, and display contents include, for example, store name display, sales floor name display, emergency exit display, floor number display, elevator display, evacuation guidance display, etc.
It is displayed only for one purpose according to its purpose, and cannot be used for purposes other than that purpose. Some indoor illuminated signboards have moving displays. For example, the display purpose of a barber's rotary signboard, etc. cannot be changed to other uses.

There are many such illuminated signboards or similar signboards inside each building, and emergency exit signs and evacuation guidance signs are scattered among them, but these are also fixed signs and there are two emergency exits. In some places, a left-facing guiding light and a right-facing guiding light are installed side by side.

In well-equipped places such as department stores, evacuation guidance can be provided using in-store public address speakers, but accidents still occur, and public address systems are rare in general multi-tenant buildings.

The present invention was developed in view of the above circumstances, and the indoor signboard, which is normally a fixed display, is replaced with a display instructing the evacuation direction in an emergency. The purpose of the present invention is to provide a new and novel indoor illumination signboard display device that broadcasts information to guide people.

The present invention aims to achieve the above-mentioned object by providing a display device having a display rotating body having a plurality of display surfaces, a speaker, a detection member for detecting the normal display position and the emergency display position of the display rotating body, and the display. The control device includes a display switching circuit, an audio synthesis section, and a display/audio control section that controls display switching and audio broadcasting. This was achieved using a device.

Any desired shape can be selected and used, such as a rectangular, linear, arrow shape, etc. It is free to cover the outer peripheral surface of the guiding member 122 with another transparent member.

Under normal usage conditions, the display rotating body 8 of the guide display 1 displays the display on the display board 11 or 12 described in the first embodiment (display examples A and B shown in FIGS. 7 and 8). The display is configured so that the display can be switched by a clear display switch 16 or a lighting display switch 17. Under normal conditions, the emergency line connection 92 is inoperative and connects the general emergency communication lines 109 and 110 to emergency signals (e.g. - non-ship emergency digital signals or emergency DT signals).
When an MF signal (MF signal, etc.) flows, the emergency signal detection unit 107 detects the emergency signal, outputs the signal, and inputs the signal to the input/output control unit 101 via the signal line 108.

Or based on the fire detection data of multiple fire detectors (guidance program control data etc. are written).

When the fire detection data signal is input to the CPU98, the CPU
The U98 specifies the address of the ROM 99, reads out the instruction code from the program memory, decodes it, outputs display, guidance, and audio broadcast data according to the instruction, inputs it to the display/audio control section 65, and performs the operations as described above. The display on the guide display 1 changes, and the i! 1I
ff'ff guidance is broadcast and the blinking light source 123 of the guiding member 122 blinks to guide the evacuation direction.

When you manually turn on the emergency switch 20 and switch the display designation switch 21 to the desired position, the signal lines 73 and 7
