BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an article collecting container used for collecting dust as an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view showing an example in which a flexible display medium (10) whose display contents can be rewritten by an electric control means is attached to a body of a container. This figure shows a state in which the flexible display medium is attached to the body portion, but since the display medium is made of a flexible material as described below, the attachment position is regardless of the container shape. It can be provided at any position where the user can easily see it (for example, a lid or the like).

FIG. 2A is a plan view of the flexible display medium,
FIG. 2B shows a block diagram.

The receiving means (input means) (12) inputs information data such as a dust collection schedule from a floppy (registered trademark) disk or a CD or by a radio system of electromagnetic induction. The input item collection schedule information is stored in the RAM, and the display program (13b) stored in the ROM counts the date and time by the timer (14), and the collection schedule at this date and time is displayed on the flexible display medium (10). To display. Besides this, of course, a display driver (15) for displaying,
Power supply unit (17), CPU (16) controlling the overall operation
And a display control unit having.

The flexible display medium (10) and another CPU (1
6), the power supply unit (17), the control unit such as the storage unit (13) do not necessarily have to be integrated, and the flexible display medium (10) is separately provided, and another CPU, the power supply unit, and the storage unit are provided. Department,
It need only be electrically connected to a control unit such as a timer. For example, as shown in FIG. 1B, the flexible display medium (1
0) may be provided on the body portion and the control portion may be provided separately on the bottom portion.

FIG. 3 shows the flexible display medium (1 shown in FIG.
An example of a structural cross-sectional view of the display section (11) 0-X line section of 0) is shown. On a flexible base material (11e) such as paper or plastic, polyethylene terephthalate (PE
T), polyethylene naphthalate (PEN), polyimide or other plastic film having excellent dimensional stability, on which an electrically conductive layer (not shown) is formed (11)
d), image display layer (11c), polyethylene terephthalate (PET), polyethylene naphthalate (PE
N), a transparent electrode film (11b) in which an active matrix electrode, a segment electrode or a simple matrix electrode (not shown) is formed on a transparent plastic film having excellent dimensional stability such as polyimide, and a surface protective layer for protecting the display portion. (11a) are laminated. The base material (11e) on the side opposite to the image display layer has an acrylic resin system that is commonly used for attaching to a collection container,
It has a urethane resin-based and rubber-based adhesive layer (11f).

The image display layer (11c) can be realized by combining an electroluminescent material, a polymer dispersion type liquid crystal, a ferroelectric liquid crystal and a display body using a microcapsule type electrophoretic system. In particular, when the microcapsule electrophoretic method is used, it is possible to display an image similar to the conventional paper.

An example of the microcapsules (110) used in this microcapsule type electrophoresis system is shown in FIG.
Methacrylic acid resin, urea resin, gum arabic, etc. are used as the capsule shell (111), and white particles (113) made of titanium oxide and black particles (114) made of carbon black are contained inside the capsule shell (111). It is dispersed and enclosed in a high dispersion medium. The white particles, titanium oxide, are positively charged, while the black particles, carbon black, are negatively charged.

Therefore, as shown in FIG. 5 (b), an electric field is applied to the two electrode films (11b, 11d) to
When the electrode film of 1b becomes the negative electrode and the electrode film of 11d becomes the positive electrode, the positively charged white particles (113) become 1
The black particles (114) are attracted to the electrode film side of 1b, and the black particles (114) are attracted to the electrode film side of 11d, so that the portion looks white when observed from above the transparent electrode side of 11b.

On the contrary, the electrode film 11b is the positive electrode, and the electrode film 11d.
When the electrode film of No. 2 becomes a negative electrode, the positively charged white particles (113) are drawn to the electrode film side of 11d, and the black particles (114) are drawn to the electrode film side of 11b. When viewed from above the electrode side, the part appears black.

The image display layer (11c) has a large number of such microcapsules (110), and by controlling the electric field of each address electrode of the electrode films (11b, 11d), FIG. Thus, a desired character or figure can be displayed with white and black pixels as if the character "A" was displayed in black.

Since each particle is dispersed in a highly viscous dispersion medium, the position of the particle does not change even if the power is turned off after the electric field is applied once, and the display image is displayed even if the power is turned off. It has non-volatility that does not disappear.

Since the display contents are maintained even when the power is cut off in this way, it is not necessary to constantly supply power while the liquid crystal display medium is being displayed. It consumes less power. Therefore, it is possible to use a power supply unit that generates power by an electromagnetic induction type generator that is interlocked with the opening / closing operation of the solar cell or the lid and charges the power.

Although the above-mentioned microcapsules contain two kinds of particles, it can be realized by using one kind of particles and coloring the dispersion medium black. That is, as shown in FIG. 6, titanium oxide, which is a white particle, is positively charged, and microcapsules dispersed in a black colored dispersion medium (115) are used to form two electrode films (11b, 11d). When an electric field is applied and the electrode film of 11b becomes the negative electrode and the electrode film of 11d becomes the positive electrode, the positively charged white particles (113) are attracted to the electrode film side of the 11b, and the dispersion medium colored black ( Since 115) is inevitably pushed down to the electrode film side of 11d, the portion looks white when observed from above the transparent electrode side of 11b.

On the contrary, the electrode film 11b is the positive electrode,
When the electrode film of d becomes a negative electrode, the positively charged white particles (113) are attracted to the electrode film side of 11d,
Since the dispersion medium (115) colored in black is inevitably pushed up to the electrode film side of 11b, the portion looks black when observed from above the transparent electrode side of 11b.

In the above example, a monochrome image is displayed, but in the case of a color image display, R (red), G (green), B (blue) divided into pixel units as shown in FIG. It can be realized by providing the color filter (11f) having the color of (1) on the transparent electrode film (11b) side to which an electric field can be applied in pixel units. That is, since the observation light in the portion where the white particles are drawn to the 11b side passes through the color filter, the color of the color filter is observed. In the example of FIG. 7, the R pixel portion of the color filter and G
In the pixel portion, white particles are drawn to the transparent electrode film side of 11b, so that R light and G light are observed, and in the B pixel portion of the color filter, black particles are drawn to the transparent electrode film side of 11b. No light is observed. As described above, by controlling the R, G, and B lights observed on a pixel-by-pixel basis, a color image can be displayed.

This display medium is made of a flexible material, and the patterning of electrodes and the like can be formed on the plastic film by a printing method or a vapor deposition method. In the image display layer (11c), the microcapsules (1
Even if there is some variation in the position arrangement of 10), there is no problem in display, and it is not always necessary to provide it on a smooth portion, and this flexible display medium can be provided at an arbitrary easy-to-see position.

FIG. 8 shows a display example of a dust collecting container provided with a flexible display medium (10) whose display contents can be rewritten by this electric control means. Timer (1
4) recognizes today's date and recalls and displays the collection schedule corresponding to this date from the storage means (13). At this time, it is also possible to display information that the user wants to be notified of, such as the next collection date and what kind of article should be taken out on which collection date. Further, it goes without saying that not only characters but also symbol marks (icons) may be displayed.

The contents to be displayed can be rewritten via the network as shown in FIG. That is, a collection schedule is distributed from the information command center to each garbage collection container provided with a display medium every time the date changes, and the distributed information data is input to the storage means (13) by a wireless or wired method. Let This information data is called from the storage means (13) and the flexible display medium (10).
To display. Alternatively, a switching circuit may be provided on the lid of the dust entrance, etc., and when the lid is opened, information data such as the collection schedule is requested via the network, and the displayed contents such as the collection schedule can be changed by the transmitted information data. Good. The method of distributing and displaying the information data via the network can naturally change the display contents of the respective article collection containers simultaneously in real time.

In the present embodiment, the garbage collection container has been described as an example, but the present invention is not limited to this and can be used as a collection container for all kinds of articles.

[0033]

As described above, since the information such as the recovery schedule is displayed on the display medium provided in the recovery container, the recovery schedule table is lost or damaged, or the recovery schedule is changed. Even in this case, it is possible to reduce the chance of accidentally taking out articles such as dust. It is possible to improve the convenience of the user by displaying what kind of items should be taken out on which collection date.

Since it is a flexible display medium, it does not necessarily have to be provided on a smooth portion, and it can be provided at an arbitrary position that is easy for the user to see, and unlike liquid crystal display media, it is less likely to be damaged by impact or the like. , Power consumption for constant display is low.

Further, since the display contents can be changed in real time via the network, it is possible to immediately respond to the change of the collection schedule and the like.
