The second transmission region 36b can transmit only one of the two colors emitted by the light emitting unit. The third transmission region 36c can transmit only the other color of the two colors emitted by the light emitting unit. For this reason, when one of the two colors emitted by the light emitting unit emits light, the first transmission region 36a and the second transmission region 36b transmit light, and a direction display indicating one direction is projected onto the floor surface. Is done. When the other of the two colors emitted by the light emitting unit emits light, the first transmissive region 36a and the third transmissive region 36c transmit light, and a direction display indicating the opposite direction is projected onto the floor surface. The Which color the light emitting part emits when a fire occurs is set when the card reader 1 is installed.

  As described above, by changing the transmission area of the transmission unit 36 depending on the color, it is possible to display either one of the two different directions depending on the projection unit 25. Also in this case, it is possible to perform a direction display that displays any one of two different directions only by setting at the time of installation.

  As another method of changing the region through which the transmission part is transmitted by the light from the light emitting part, the polarization direction can be used instead of the color. In this case, the light emitting unit is configured to emit one of the lights with different polarization directions, and the region of the transmission unit indicating the direction is configured to transmit only the light with one of the polarization directions. That's fine.

  In the embodiment described so far, the direction display is projected from the projection unit 23 onto the floor surface in order to display the evacuation direction. However, if the card reader 1 displays the evacuation direction, an appropriate configuration is adopted. It's okay. For example, the transmissive part 32 and the light emitting part 31 may be arranged on a horizontal straight line, and the direction indication may be projected onto the wall surface facing the card reader 1. Further, the evacuation direction display unit is not limited to the projection unit, and the light emitting unit or the card reading unit of the card reader 1 may be used as the evacuation direction display unit, and the evacuation direction may be displayed on these.

  Further, in the above-described embodiment, the transmission part 32 is set to be horizontal or nearly horizontal with the floor surface, but the transmission part 32 may be inclined with respect to the floor surface. By configuring in this way, it becomes possible to display the direction indication displayed at a position near the bottom of the card reader 1 at a position far from the card reader, so the direction indication can be displayed near the center of the passage. It becomes.

  In the above-described embodiment, when a fire alarm is acquired from the disaster prevention receiver 45, the direction is displayed from the projection unit 23. For example, the direction is displayed even in a state where the fire alarm is not acquired during an operation test or the like. It may be. Since the function of displaying the direction indicating the evacuation direction in an emergency is a function that is not used in normal times, inspection work is required. The operation test may be performed by the local control panel 41 or may be performed by operating the card reader 1. When the operation test is performed by the local control panel 41, the local control panel 41 transmits a direction indication command to all the card readers 1 in the facility or the card readers 1 in a specific area, and the inspector The card reader 1 confirms whether the direction is displayed. When the inspection is performed by operating the card reader 1, the card reader 1 is displayed by one direction and confirmed by a predetermined operation such as a card reading by the inspection manager and a long button press.

  In addition to the above-described embodiment, the card reader 1 may have a power supply unit for the light emitting unit 31 independently. The card reader 1 operates with power supplied from the local control panel 41. However, when the number of card readers 1 connected to the local control panel 41 is large, the current value sent from the local control panel 41 may be insufficient. is there. When the direction is displayed by the card reader 1, power shortage can be prevented by supplying power from the power supply unit for the light emitting unit 31. The power supply unit for the light emitting unit 31 may be charged from the local control panel at normal times. Further, when no power supply unit is provided, shortage of current can be prevented by preventing all card readers 1 from being turned on simultaneously. For example, each card reader 1 may be sequentially blinked so as to guide in the evacuation direction.
