The transparent plate 11W is attached to an opening 11O formed in the door 11 of the housing 10. The transparent plate 11W can be made of a transparent material such as glass or acrylic, and is provided to protect the display section 20I of the display sheet 21 from dirt, scratches, and the like.

The map printing sheet 21A of the display sheet 21 is placed behind the transparent plate 11W when viewed from the front, and is a transparent sheet made of, for example, a transparent resin film. The map printing sheet 21A has a display section 20I on its surface, and a block diagram 21S of buildings and sites is printed on the display section 20I. In addition to the division of plots, the plot plan 21S also includes the arrangement of equipment such as smoke prevention equipment, numbers or symbols corresponding to the compartments, and numbers or symbols corresponding to the equipment such as smoke prevention equipment. These symbols are the lighting symbols 21L on which the light from the light source 23 is projected. Note that the zoning map 21S may be printed on the map printing sheet 21A by a method such as laser printing or inkjet printing, and can be performed using an office printer or the like.

The background sheet 21B of the display sheet 21 is disposed on the back side of the map print sheet 21A when viewed from the front, and is, for example, a transparent resin sheet painted translucent by UV printing or the like.

The light source panel 22 is placed behind the background sheet 21B when viewed from the front, and is made of a transparent plate material, such as glass or acrylic. The light source panel 22 can be attached to the map printing sheet 21A and the background sheet 21B by, for example, screwing screws 22B through through holes (not shown) formed in the light source panel 22 and into screw holes 11H formed in the door part 11. It is fixed while being pressed against the portion 11.

The light source 23 is, for example, an LED, arranged in accordance with the position of the lighting symbol 21L, and adhered to the light source panel 22 with an adhesive sheet (not shown) or the like. Further, the light source 23 is connected to the map section board 20S via the map section wiring 20C, and emits or blinks based on a control signal transmitted from the main body board 12S to the map section board 20S.

FIG. 4 is a left side view of the map printing sheet 21A, the background sheet 21B, the light source panel 22, and the light source 23 when they are installed. When installed, the map printing sheet 21A, the background sheet 21B, the light source panel 22, and the light source 23 are arranged in this order when viewed from the front. By locking the head of the screw 22B that penetrates the light source panel 22 to the light source panel 22 and screwing the tip into the screw hole 11H of the door part 11, the map printing sheet 21A, the background sheet 21B, and the light source panel 22 are Fixed relative to receiver 1.

In the operation display panel section 30, an operation switch (not shown) on a panel surface 30I is connected to an operation display panel section substrate 30S via an operation display panel section wiring 30C. Based on the control signal transmitted from the main body board 12S to the operation display panel board 30S, the operation display panel section 30 emits an alarm sound through a speaker (not shown) or operates an operation switch (not shown) arranged on the panel surface 30I. Based on this, it is possible to stop the alarm sound, etc.

Next, the operation of the receiver 1 upon detection of a predetermined event will be described. An example of an event to be detected is the occurrence of a fire.

FIG. 5 is an example of the block diagram 21S. For example, assume that a fire has occurred in a compartment corresponding to compartment "1" on the left side of the compartment diagram 21S. When a fire occurs, a fire detector (not shown) connected to the receiver 1 detects the fire. A detection signal from the fire detector is sent to the main body board 12S via an external line 12C.

The main body board 12S specifies the fire detector that is the source of the received detection signal, and sends a signal to the map part board 20S via the map part wiring 20C so as to cause the light source 23 corresponding to section "1" to emit light. send.

Then, power is supplied from the map section board 20S to the light source 23 corresponding to the section "1" via the map section wiring 20C, and the light source 23 corresponding to the section "1" emits light.

When the light source 23 emits light, the light from the light source 23 passes through the transparent light source panel 22 and the translucent background sheet 21B, and is projected onto the lighting symbol 21L corresponding to section "1" printed on the map printing sheet 21A. Ru.

When the light from the light source 23 is projected onto the lighting symbol 21L, when the receiver 1 is viewed from the front, the lighting symbol 21L corresponding to the section "1" appears to be lit or blinking, as shown in FIG.

Next, a method of updating the display unit 20I when the division of buildings, grounds, etc., or the arrangement of sensors, smoke prevention equipment, etc. is changed will be explained.

If there is a change, prepare a new transparent resin film and print the changed block diagram 21S on the display section 20I on the surface of the resin film using laser printing or inkjet printing using an office printer. A new map print sheet 21A is created and replaced with the old map print sheet 21A.

In addition, by replacing the light source 23 in a position that corresponds to the position of the new lighting symbol 21L, the receiver 1 can be adapted to the changed zoning and the arrangement of sensors, smoke prevention equipment, etc. can be done.

The receiver 1 of this embodiment, which is configured and operated as described above, has the display sheet 21 composed of the map printing sheet 21A and the background sheet 21B, so that it can be used for dividing buildings, grounds, etc., and for sensing. When the arrangement of equipment, smoke prevention equipment, etc. is changed, the receiver 1 can cope with the change by replacing the map printing sheet 21A. Note that the map print sheet 21A can be easily created by printing on a transparent sheet using an office printer or the like. Furthermore, since the background sheet 21B is semi-transparent, when the receiver 1 is viewed from the front, the light from the light source 23 passes through, but the map wiring 20C of the light source 23 is not visible through it, improving visibility. .

In other words, in order to improve the visibility of a parcel map, it is necessary to make the background of the parcel map semi-transparent, but painting a transparent sheet semi-transparently by UV printing, etc. is generally done by laser printing. This is more difficult than printing a block diagram on a transparent sheet using inkjet printing or the like. Therefore, the map printing sheet 21A is provided separately from the background sheet 21B instead of printing the parcel map directly on the background sheet 21B, which is a translucent sheet, so that when the parcel map is changed, only the map printing sheet 21A can be reprinted. You can just replace it. In other words, there is no need to perform UV printing or the like again, and it is possible to easily change the block diagram.

Although one embodiment of the receiver according to the present invention has been described above, the present invention is not limited to the above-described one embodiment, and can be modified as appropriate without departing from the spirit thereof.

For example, a cushioning material (light absorbing member) of black or the like is inserted between the holding plate 24 and the light source panel 22, and the cushioning material absorbs light from the front side, and directs the light coming from the front side from the holding plate 24 toward the front. It is also possible to adopt a configuration that reduces the reflected light and prevents the map portion wiring 20C and the like from being seen through.

The background sheet 21B may be any sheet that allows the light from the light source 23 to pass therethrough while making the map section wiring 20C invisible. The background sheet 21B is not a sheet of transparent resin painted translucent, but, for example, a paper material with many fine holes penetrating the surface of the paper to allow light to pass through. The map section wiring 20C may be made invisible while allowing the light from the light source 23 to pass therethrough.

By not providing the background sheet 21B and painting the light source panel 22 semitransparently by UV printing or the like, the map part wiring 20C of the light source 23 is prevented from being seen through when the receiver 1 is viewed from the front. You can also do this.

The light source 23 may be anything other than an LED, as long as the light emitted by the light source 23 passes through the background sheet 21B, or may be an incandescent bulb or a fluorescent lamp.
