Next, referring to the block diagram shown in FIG.
The circuit configuration and operation of the auxiliary lamp 30 and the fluorescent lamps 6a to 6d in the present embodiment will be described.

The fluorescent lamps 6a to 6d provided on the fixed shelf 1 and the moving shelves 3 are connected to the uninterruptible power supply 1 as shown in FIG.
2 is connected to a power cable 15b disposed between the movable shelves 3. The power cable 15 b is branched into a normal power line 21 and an emergency power line 22 on the downstream side of the power switch 14.

On the other hand, an input voltage detection circuit (not shown) is provided in the uninterruptible power supply 12 so as to detect an input voltage from a normal power supply. The input voltage detection circuit supplies the power to the normal power supply line 21 via the relay 20 when the power is supplied from the normal power supply.
When the supply of electricity from the normal power supply is interrupted, the relay 20
The power is supplied to the emergency power supply line 22 through the power supply line.

Each fluorescent lamp 6 connected in parallel as shown in FIG.

It is automatically turned on / off based on a command from the PU.

The above-described limit switch 8 is provided between the b-contact and the fluorescent lamps 6a to 6d. When the adjacent shelves are in an adjacent state, the limit switch 8 is turned off and the fluorescent light is turned off. When electricity is not supplied to the lamps 6a to 6d and the adjacent shelves are separated from each other to form a passage, the limit switch 8 is turned on to turn on the fluorescent lamps 6a to 6d.
Side is supplied with electricity from the emergency power supply line 22.

Here, in the case where the supply of electricity to the normal power supply line 21 is cut off and power is supplied from the emergency power supply line 22 to the fluorescent lamps 6a to 6d via the limit switch 8, the driving circuit 23 Since the electromagnetic switch 24 is opened, power is supplied only to the fluorescent lamp 6a on the near side in FIG. 1, and power is not supplied to the other fluorescent lamps 6b to 6d.

That is, when the supply of electricity from the normal power supply 13 is interrupted due to the occurrence of a power failure or the like, electricity is supplied from the battery 10 of the uninterruptible power supply 12 to the emergency power supply line 22. When a passage is formed, the limit switch 8 is turned on, only the fluorescent lamp 6a of the plurality of fluorescent lamps 6a to 6d is turned on, and when no passage is formed, the limit switch 8 is turned off, All the fluorescent lamps 6a to 6d are turned off.

By the irradiation light from the auxiliary light 30, the operation switch 28
(Emergency operation switch 18) and its vicinity become bright,
In addition to being able to confirm the position, there is no danger of erroneous operation and it is safe.

Further, since the auxiliary light 30 is provided on the side plate 3a, the user in the passage can easily confirm the position of the side plate 3a at the time of a power failure, so that the auxiliary light 30 also functions as a guide light. This means that the user can use the auxiliary light 3
It can be safely moved out of the passage using the irradiation light from 0 as a guide.

Next, another embodiment of the circuit configuration relating to the auxiliary lamp 30 will be described with reference to the block diagram of FIG.

The circuit configuration of the present embodiment is different from that of the above-described embodiment in that an illuminance detection sensor 32 capable of detecting ambient illuminance is provided, for example, at a predetermined upper portion of the fixed shelf 1 and each movable shelf 3. The point is that a switch unit 33 connected to the illuminance detection sensor 32 is provided between the auxiliary light 30 and the c-contact of the emergency power supply line 22. The other similar circuit components are denoted by the same reference numerals, and detailed description thereof will be omitted.

The switch section 33 is closed when the illuminance value detected by the illuminance detection sensor 32 becomes lower than a predetermined illuminance value.

Therefore, for example, when electricity is supplied to the emergency power supply line 22 due to the occurrence of a power failure, the auxiliary light 30 is turned on only when the illuminance detected by each illuminance detection sensor 32 is equal to or less than a predetermined value. When the detected illuminance is equal to or more than the predetermined value, the auxiliary light 30 is not turned on.

As described above, by illuminating the auxiliary lamp 30 based on the detection result of the illuminance detection sensor 32, even when a power failure or the like occurs, for example, some factor (for example, external light from a window) or the like is applied. Even if the surroundings have a certain level of brightness and the operation switch 28 and the emergency operation switch 18 can be sufficiently operated, the auxiliary light 30 is turned on to prevent the battery from being wasted. it can.

In particular, in the case of this embodiment, when the fluorescent lamp 6a is turned on in an emergency and the periphery of the passage becomes bright, the operation switch 28, the emergency operation switch 18 and the like are controlled to some extent by the irradiation light from the fluorescent lamp 6a. It may be brighter. Therefore, for example, if the illuminance detection sensor 32 is provided near the fluorescent light 6a of the fixed shelf 1 or each movable shelf 3, even if a power failure occurs, at least the auxiliary light 30 near the passage is provided.
Is not lit, so that the battery 10 is not wasted.

The position of the illuminance detection sensor 32 is as follows.
It is not limited to the above-mentioned fixed shelf 1 and the predetermined upper part in each movable shelf 3, but can be arranged at any arbitrary position.
Needless to say, it is preferable to dispose it in a place that is hardly affected by the irradiation light of the auxiliary lamp 30.

Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to the above-described embodiments, but can take various embodiments.

For example, in the above embodiment, the auxiliary light 30 as a light emitting body is constituted by an LED lamp, but it goes without saying that various light emitting devices other than the LED lamp may be used.

Further, an auxiliary light may be provided on the operation switch 28 itself shown in FIG. 2 so that the operation section itself emits light.

In the embodiment based on FIG. 5, the illuminance detection sensors 32 are provided individually corresponding to the auxiliary lights 30 provided on the fixed shelf 1 and the movable shelves 3, respectively. Only one of the auxiliary lamps 30 may be provided for every three or the like based on the detection result of one illuminance detection sensor.
