摘要： It is an object of the present invention to provide a technique relating to an electronic shelf label system that is capable of suppressing malfunction of an electronic shelf label caused by the increase of internal resistance of a battery. In order to achieve this object, in an electronic shelf label system of the present invention, an electronic shelf label 5 includes a battery 56 for supplying power of this electronic shelf label 5, a to-be-charged part 572 to be charged by power supplied from the battery 56, a light emission part 52 for sending data to a distribution device by using power accumulated in the to-be-charged part 572, and a boost circuit 571 and a control circuit 570 for controlling power supplied from the battery 56 to the to-be-charged part 572. In the electronic shelf label 5, on receipt of change notification data from the distribution device, a charge operation mode of this electronic shelf label 5 is changed from a normal charge mode to a long-term charge mode in which the to-be-charged part 572 is charged in a period of time longer than that in the normal charge mode. Power supplied from the battery 56 to the to-be-charged part 572 is lower in the long-term charge mode than in the normal charge mode.

摘要： It is an object of the present invention to provide coding techniques which allow for higher efficiency and easier synchronization with coded data. In order to attain the object, a coding device according to the present invention converts 2-bit informational data into 4-bit coded data according to a predetermined coding rule. According to the coding rule employed in the coding device, one of four possible kinds of bit strings of informational data is converted into alternately a bit string of four bits in which each of values of two successive bits is “1” and a bit string of four bits in which each of values of all bits is “0”. Then, the other kinds of bit strings are converted into bit strings of four bits which differ from one another, in each of which a value of only one bit is “1”.

摘要： It is an object of the present invention to provide techniques which allow for lower power consumption of electronic shelf labels. In order to attain the object, electronic shelf labels according to the present invention are located to respectively correspond to products, and each of the electronic shelf labels displays product data of its corresponding product. Each of the electronic shelf labels repeatedly performs “sleep operations” in which predetermined functions are stopped for a predetermined time period, at given time intervals, and the predetermined time period is extended when non-receipt of data continues for a specified time period.
