Description

The present invention relates to a transmitter that is attached to a storage box for disaster prevention equipment , a wall surface, or the like and that is operated in the event of a fire to notify the occurrence of an abnormality.

Conventionally, transmitters for disaster prevention equipment have been installed in storage boxes for fire prevention equipment, fire hydrant boxes, wall surfaces, etc., provided with a push button switch on the transmitter body side, and turned on by pressing a protective plate placed on the cover side. Operate and send a fire report signal to the receiver to alarm. The fire hydrant box accommodates a transmitter, a position indicator, and the like as disaster prevention equipment. In addition, the disaster prevention equipment accommodation box is provided with an acoustic hole on the front cover plate side and a bell on the main body side.

The position indicator lamp is a red indicator lamp that is always lit to indicate the location of the disaster prevention equipment storage box so that in the event of an emergency, the surrounding people can recognize the location of the transmitter. When the receiver receives a fire alarm signal from the transmitter and outputs a fire alarm, the disaster prevention equipment storage box sends out a district acoustic signal to the transmitter, thereby ringing the bell of the disaster prevention equipment storage box and fires. An alarm sound is output (Patent Document 1). Similarly, when a transmitter is attached to a fire hydrant box or a wall surface, it is installed in a set with a position indicator for making a building user recognize the position of a disaster prevention device such as a transmitter.

By the way, when such a transmitter or the like is installed, it is necessary to secure a space for installing each disaster prevention device as a set. In recent years, in order to reduce this installation space, the storage box for disaster prevention devices has been downsized. For this reason, it has been proposed that the position indicator lamp is abolished and the transmitter is provided with a position indicator lamp. In a transmitter in which a position indicator lamp is integrally provided, a transmitter in which a position indicator lamp is arranged so as to surround a push button switch provided in the transmitter has been proposed (Patent Document 2). The position indicator lamp provided so as to surround the push button switch has a plurality of LEDs distributed and a sheet-like light emitting member is arranged in front of the transmitter to emit light in a planar shape.

Japanese Patent Application Laid-Open No. 9-102085 Japanese Utility Model Publication No. 5-66794

However, when a transmitter equipped with a position indicator lamp in which a sheet-like light emitting member is arranged in front of the transmitter so as to surround the conventional push button switch is attached to the disaster prevention equipment storage box , the sheet-like light emitting member Since the light emitting surface is flush with the cover plate surface of the device storage box, there is a problem that the visibility of the position indicator lamp is lowered when the disaster prevention device storage box is viewed from the lateral direction.

In order to solve this problem, a transmitter may be attached so that the light emitting surface protrudes outward from the mounting surface of the storage box for disaster prevention equipment , as in the case of the position indicator lamp provided independently in the past, As a result of the protrusion, the installation space for the storage box for disaster prevention equipment will increase.

  In addition, it is possible to maximize the display area as the position indicator lamp by arranging the sheet-like light emitting member in front of the transmitter so as to surround the push button switch, but the light from the light source is incident. In order to uniformly emit the sheet-like light emitting member that emits light with the required brightness, for example, when LEDs are used as the light source, it is necessary to distribute and arrange a large number of LEDs behind the sheet-like light emitting member. However, there is a problem that the cost is increased due to complexity, and the power consumption is increased.

  In addition, there is a telephone jack that is covered with a door inside the transmitter body. In this case, a sheet is provided so as to surround the telephone jack door on the surface of the transmitter and the protective plate of the pushbutton switch. The light emitting member is disposed in front of the transmitter, and the display area is reduced, the shape of the sheet light emitting member is complicated, and the LED distribution arrangement corresponding to this is complicated.

The present invention does not impair the visibility from the lateral direction and does not increase the installation space of the storage box for disaster prevention equipment , and further includes a position indicator lamp having a display part that effectively utilizes the exposed surface of the transmitter surface cover. The purpose is to provide a transmitter.
