Embodiment Construction

[0024] One embodiment of the present invention will be described below based on the drawings. This embodiment shows an example of application to an electronic shelf label system used in stores such as supermarkets as an optical communication system using solar cells.

[0025] System Overview

[0026] figure 1 It is a system configuration diagram schematically showing the electronic shelf label system 1 of this embodiment. like figure 1 As shown, the electronic shelf label system 1 consists of a plurality of electronic shelf labels 2 as receiving devices that display commodity data such as unit prices of commodities, a portable terminal 3 that transmits commodity data to the electronic shelf labels 2, and a portable terminal The shop computer 4 etc. as the master device which distributes commodity data on 3 constitutes. The number of objects of the portable terminal 3 may be one or more. Roughly speaking, this electronic shelf label system 1 performs optical communication ...

Abstract

The invention provides an optical communication system and a receiving device. The optical communication system includes a transmitting device which is equipped with a light source and a receiver which is equipped with a solar cell that transforms lights into electricity and uses the electricity transmitted by the solar cell as a driving power source. The transmitting device uses the light source to transmit digital data into light signals to be transmitted. The receiver transmits the light signals into digital data according to the generating capacity of the solar cell corresponding to the received light signals. Thus, the optical communication is realized. And a wireless communication device which is only used for the wireless communication is not required to be arranged on the receiver as before.

Description

technical field [0001] The invention relates to an optical communication system and a receiving device. Background technique [0002] In the past, on the product display shelves of stores such as supermarkets and convenience stores, shelf labels corresponding to the displayed products were installed, so that customers can easily confirm the product name, unit price, specification (quantity), and special price display of the displayed products. and other commodity data. Generally, a card type such as paper is used as such a shelf label, and product data such as a product name and a unit price of the relevant product are printed by a printer. [0003] However, according to this shelf label, for example, in the case of changing the unit price from tomorrow, etc., after the store is closed, the clerk must replace the shelf label corresponding to the changed product with a new shelf label. It takes a lot of labor and time. In addition, in the case of setting a time period for ...
