Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an occupancy display device for displaying the presence / absence of an occupant working in an office, and particularly to an occupancy in an office or the like in which a partition is installed between individual seats. Regarding display device.

[0002]

2. Description of the Related Art Recently, many offices have partitions installed between individual seats so that the office workers can concentrate on their work without being distracted by surrounding events. There is.

Although such an office room can improve the work efficiency of each office worker, on the other hand, the partition obstructs the visibility of the office room, and whether a person is present in each seat. There is an inconvenience that it is not easy to know whether or not you are absent.

In order to eliminate this inconvenience, a means for detecting the presence of a person is attached to each seat, and an appropriate display means is controlled by the detection signal to determine whether or not a person is present in each seat. A means for displaying whether or not the person is absent is proposed.

For example, Japanese Unexamined Patent Publication No. 63-163599, entitled "Attendance Detection System", attaches an occupancy sensor to a chair in an office, a conference room, or the like and a signal transmitted from the sensor. Is processed by a computer to turn on the indicator light corresponding to the seat of the indicator lamp panel installed on the wall surface or the like in the room, thereby remotely detecting the seated state.

Further, Japanese Unexamined Patent Publication No. 64-46897, entitled "Attendance Display System," presents a pressure-sensitive switch mounted on a chair, a transmitter and a power source for operating them, and a room near the chair. A receiver mounted on the member, an LED display unit, and a power supply for operating these units are provided, and when a person sits in a chair, the pressure-sensitive switch operates, and the LED display unit is turned on via the transmitter and the receiver. The means for doing so is described.

There is also known an inversion display device in which an electromagnet is used to invert a rotating body provided with a required display on both opposing surfaces instead of the light emitting body.

[0008]

The means described in each of the above-mentioned publications is a light bulb, a fluorescent lamp or an LE as a display means.
Since an optical display such as a light emitting element such as D is used for optical display, it is necessary to continuously light these elements depending on the state of presence or absence of seats, which results in a large power consumption.

A liquid crystal panel can be considered as a display means that consumes less power. However, the liquid crystal display has a weak contrast, which makes the display unclear in a bright room and is difficult to read depending on the viewing angle direction. There is a problem such as.

Since the reversing display means for reversing the rotating body by the electromagnet can be visually recognized only from one direction, the display device is installed above the partition so that the seating can be confirmed from each of the surrounding directions. In this case, it is necessary to install a rotating body or the like on each surface of the display device, which causes a problem of being expensive.

In view of the above-mentioned problems of the prior art, the present invention automatically detects whether or not a person is seated in a seat surrounded by a partition so that it can be visually recognized from the surroundings with a small amount of power consumption. It is an object of the present invention to provide an attendance display device that can be displayed as desired.

[0012]

In order to achieve the above object, the present invention provides a seat surrounded by a partition with a detection means for detecting whether or not a person is present and outputting a signal. In a seated display device that displays the presence / absence of the seat based on the signal, a hollow cylindrical shape whose axis is vertical is formed, and a plurality of display windows are cut on the outer peripheral surface of the seated space above the partition. Mounted on the case, and the inside of the case has a cylindrical shape with a vertical axis and is rotatably supported around the vertical axis within a required angle range, and has two types of characters and symbols that indicate whether or not there is a seat on the outer peripheral surface. And so on are displayed in a plurality of sets corresponding to the number of display windows, and the regions where one of the two types of characters and symbols is displayed at both ends of the rotation stroke are displayed so as to face the corresponding display windows. Based on the rotation indicator and the signal from the seat detection means, To any one end of the rotary stroke 示体, rotary drive means for selectively rotating, characterized in that it comprises and.

The case is formed as a square tube having a square cross section, a display window is cut on each surface of the square tube, and the rotary display is provided with two long diameters (d) larger than the inner dimension (D) of the case. ₁ ) and two minor diameters (d ₂ ) smaller than the inner dimension (D) of the case are 4
It may be formed in a rectangular tube having an octagonal cross section alternately arranged at an angular position of 5 degrees, and two kinds of characters, symbols, etc. may be alternately displayed on each surface of the octagonal rectangular tube.

Alternatively, the case and the rotary display body are formed in a concentric cylindrical shape, and one of them is provided with a hit, and the other is provided with a stop piece so as to face each other to limit the rotation angle range of the rotary display body with respect to the case. You may do it.

The rotary display is formed into a cylindrical shape having a lower end opened and an upper end surface closed by a support plate. The rotary display is mounted on the upper end of an output shaft erected in the center of the case and rotates in a horizontal plane. It is desirable to rotate the rotary display body by mounting the support plate and rotationally driving the output shaft.

[0016]

When the rotation driving means is operated based on the output from the detection means for detecting the presence or absence of a person in the seat, the rotation display member is rotated to one end or the other end of the rotation stroke. At the stop position, the characters, symbols, etc. indicating the presence or absence of the seat displayed in the peripheral surface area of the rotary display face the display window of the case, and display the presence or absence of the person in the seat.
