Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a housing used to accommodate a large number of box-shaped units.

[Prior art]

When housing a box-shaped unit with various electronic circuits mounted on it, a shelf-shaped chassis is generally used, and after housing the unit, the chassis is attached to a housing such as a rack or console. As a result, the structure becomes complicated and expensive, and when adding more units, it is necessary to add a chassis, resulting in disadvantages such as a lack of expandability.

As a countermeasure against this problem, a case structure has been proposed in which the units are connected vertically to the frame and then the frame is attached to the open surface of the outer case. This addition improves expandability; however, when the outer casing is made of sheet metal, it has an open surface, so when accommodating a large number of frames connected horizontally, the open surface is The ceiling panel is extended in the lateral direction, reducing its strength and requiring some form of reinforcement.If reinforcement is performed, the number of machining operations for the outer casing increases, resulting in an increase in cost.

[Summary of the idea]

The present invention has the purpose of eliminating such drawbacks of the conventional method at once, and the side plates of frames housed in an outer casing having an open surface for accommodating a plurality of frames connected in the horizontal direction can be moved along the vertical direction. To provide an extremely effective case for a box-like unit, which has a bent part for reinforcing the frame, and the outer case can also be reinforced by attaching a frame to an open surface.

[Example] The present invention will be explained in detail below with reference to figures showing examples, but first, an example of a box-shaped unit will be explained.

Figure 1 shows the external appearance of a guest room management unit used at hotel receptions, etc., where A is a plan view, B is a front view, C is a rear view, and D is a side view. Insert slots 2a to 2 for inserting key tags correspond to multiple guest rooms.

The same holds true.

Further, sensors 103 and 104 each consisting of a light emitting element and a light receiving element are provided in correspondence with the guides 101 and 102 and in a state where they are held in place.
These are used to detect the insertion state of the tag 105.

Therefore, if the tag 105 is inserted at an angle guided by the guide 101, the left side of the tag 105 blocks light between both elements of the sensor 103, so this state is electrically detected and the tag 105 is guided by the guide 101.
If inserted at the angle guided by sensor 02, sensor 1
This condition is similarly detected by 04.

For this reason, if the insertion angle of the tag 105 is determined, for example, horizontally when the guest room is vacant, and tilted when the guest is out, the tag 105 attached to the guest room key can be inserted from the insertion slot 2d at a predetermined angle. By inserting it, the state of the cabin can be reported to the central control device.

The same applies to the insertion ports 2a to 2c, and the status of each guest room is individually given to the central control device.

Furthermore, if the tag 105 is not inserted, the guest room is in use and both sensors 103 and 104 do not detect the tag 105. Based on these detection capabilities, the central control device determines whether the guest room is in use. can be judged.

In addition, on the back side of the message insertion slot 3d,
The pocket 106 is the same for the message insertion slots 3a to 3c, and the room occupancy indicator light 6
In response to commands from the central control device, for example, the lights a to 6d turn off when the room is vacant, turn on continuously when the room is in use, and blink when the room is out, and the cleaning indicator lights 7a to 7d turn on and blink continuously in response to similar instructions. The message indicator light 8a indicates that cleaning is in progress and inspection is complete.
-8d are designed to turn on and off in response to similar commands based on the operations of switches 9a-9d.
