CONSTITUTION:As to the bar code panel provided with a bar code display part utilized for identifying same merchandise which is bonded or attached to the merchandise, etc., a liquid crystal variable bar code display part 1 displays an arbitrary bar code 1 (a) based on a bar code setting signal to be inputted through an input part 4 via a driver 2 formed by a single ASIC tip or seceral tips. Accordingly, the bar code panel can be used repeatedly by recording the arbitrary bar code or changing the display. It is desirable to use a thin battery such as a paper battery, a button battery and optical battery as a power source 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code plate provided with a bar code display part which is attached to or bonded to a product or the like and is used for identifying the product, and is particularly displayed on the display part. The present invention relates to a bar code plate in which a bar code can be set arbitrarily.

[0002]

2. Description of the Related Art Generally, a bar code tag (or bar code plate) having a bar code printed thereon is attached to a product or the like, or a bar code is printed on a wrapping paper of a product. Items are identified by reading them with a bar code reader.

By the way, since a bar code is conventionally printed on a bar code label or a wrapping paper, it is impossible to reuse it for another product. , Bar code slips, etc., are once used and then discarded as disused items. Also, once attached, the same item cannot be changed.

The present invention is intended to solve such a problem in the prior art, in which the bar code display section is composed of liquid crystal or the like, and the bar code displayed on the display section is arbitrarily set. It is an object of the present invention to provide a deformable bar code plate which is provided with a drive means which can be used, and which enables reuse of the bar code plate and change or addition of an initially set code.

[0004]

In order to achieve the above-mentioned object, the variable bar code plate of the present invention, in the bar code plate, is capable of setting an arbitrary bar code on the bar code display section and the same display section. It is characterized by having a drive means.

[0005]

In the variable bar code plate of the present invention described above, the bar code displayed on the bar code display section can be arbitrarily set by the drive means, so that the bar code plate can be repeatedly used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A variable bar code plate as an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of the principle, and FIGS. 2 to 5 are side views of the first to fourth embodiments. FIG. 6 is a plan view, and FIG. 6 is a schematic view showing an example in which a deformable bar code plate is used as a system.

First, the principle will be described with reference to FIG.
Indicates a liquid crystal type bar code display section, and the bar code display section 1 is a driver (this driver is, for example, AS
It is driven by an IC (one chip or several chips) 2 and receives a barcode setting signal from the input section 4 to display an arbitrary barcode 1a. Reference numeral 3 indicates a power source, and it is desirable that the power source 3 is thin such as a paper battery, a button battery, or a photocell.

It is also possible to use an EL (electroluminescence) or other light emitting element as the bar code display portion 1.

Next, a first embodiment of the deformable bar code plate manufactured on the basis of the above principle will be described with reference to FIG. 2. The bar code display portion 1 is provided on the back plate 8 via the battery 3.
Is installed. Reference numeral 5 indicates a liquid crystal portion of the barcode display portion 1, reference numeral 6 indicates an IC as a driver, and the IC 6 is mounted on the substrate of the display portion 1. The deformable bar code plate is used by attaching the back plate 8 to a product or the like with an adhesive or the like.

Next, the second embodiment shown in FIG. 3 will be described. In the variable bar code plate of this embodiment, an IC card 7 is used instead of the back plate in the first embodiment. That is, while the liquid crystal bar code display unit 1 and the battery 3 are attached to the surface of the IC card 7, the IC
An IC chip 6 as a driver and an input / output terminal 4 for setting a barcode are attached to the back surface of the card.

Further, in the variable bar code plate of the third embodiment shown in FIG. 4, a non-contact type IC card 7a is used instead of the IC card of the second embodiment, and further input The input / output coil 4a is used as a part.

Incidentally, this third embodiment and the above-mentioned second embodiment
In the embodiment, an IC module may be used as the IC chip 6.

Further, in the variable type bar code plate of the fourth embodiment shown in FIG. 5, a remote control type IC card 7b is used instead of the IC card in the case of the second embodiment. A liquid crystal bar code display unit 1 and a battery 3 are attached to the IC card 7b. It should be noted that the battery 3 in this example may be of a type in which electric power is externally supplied instead of being placed on the IC card 7b. Further, the input section is configured as the antenna 4b.

As in the second to fourth embodiments described above,
When an IC card is used, the display section may be used for displaying other than the barcode including numbers and characters.

Next, FIG. 6 shows an example in which the variable bar code plate of each of the above-described embodiments is used as a system. In FIG. 6, reference numeral 10 indicates the variable bar code plate. Then, the input unit 1 of the recording signal or the display change signal is input to the input unit 4 of the variable bar code plate 10 by the input unit
It is possible to record an arbitrary code on the deformable barcode plate 10 by operating 1 and to display an arbitrary barcode on the display unit 1. The bar code displayed on the display unit 1 is read by the reading device 12 to identify the product. If the reading device 12 is provided with the same function as the input device 11, bidirectional communication is possible with this system.

[0016]

As described in detail above, according to the variable bar code plate of the present invention, unlike the conventional fixed bar code system, the code of the bar code plate attached product can be changed depending on the conditions. In addition to being able to be used repeatedly, communication is also possible via a bar code plate, which has a remarkable effect that it can be used in a wide range of applications.
