  "abstract": "A display apparatus is provided with an interface, a storage device, an antenna and a processing device. The interface connects to a given network. The storage device stores data to be used to perform a communication with an external host controller via the network. The antenna performs a near field communication with an external terminal. The processing device transmits the data to the terminal in response to a request from the terminal and stores other data received from the terminal in response to another request from the terminal in the storage device.",
  "claims": [
    "1. An operation assist system configured to visually indicate a given operation target selected among a plurality of targets, comprising: a display apparatus configured to perform a communication with an external host controller via a given network; and a terminal configured to perform a near field communication with the display apparatus, wherein the display apparatus comprises: a connection interface configured to be connected to the network; a first storage device configured to store data to be used for communication with the host controller; and a first antenna configured to perform the near field communication with the terminal, wherein the terminal comprises: a second antenna configured to perform the near field communication with the display apparatus; a processing device configured to request, in a first operation state, the display apparatus to transmit the data by the near field communication; and a second storage device configured to store the data received from the display apparatus, wherein the terminal transmits, in a second operation state different from the first operation state, the data to another display apparatus that will replace the display apparatus by the near field communication.",
    "2. An operation assist method for visually indicating a given operation target selected among a plurality of targets, the method including: performing, by a display apparatus, a communication with an external host computer via a given network by use of data stored in a first storage device; performing, by a terminal, a near field communication with the display apparatus, wherein performing the near field communication includes: a first operation; and a second operation, wherein the first operation includes: requesting, by the terminal, the display apparatus to transmit the data; transmitting, by the display apparatus, the data to the terminal in response to the requesting; receiving, by the terminal, the data; storing, by the terminal, the received data in a second storage device, wherein the second operation includes: transmitting, by the terminal, the data to another display apparatus that will replace the display apparatus; and receiving, by the another display apparatus that will replace the display apparatus, the data."

  "description_excerpt": "The present invention relates to a display apparatus, an operation assist system using this display apparatus and an operation assist method using this operation assist system.\n\nAs an example of an operation assist system using a display apparatus, there is a picking assist system. In picking operations, various items are stored in reservoirs such as shelves and an operator selectively takes out arbitrary items which are operation targets, among those items. At that time, items which are operation targets may be visually shown by use of display apparatus, so that the operator does not mistake. For example, items to be taken out may be indicated to operator by displaying, under remote controls of display apparatus, that are arranged in association with each item, by a host controller connected to a same network as those display apparatuses. Systems to assist such picking operations are broadly used, for example, in production lines, logistics bases, or the like.\n\nIn such operation assist systems, a same number or more of display apparatuses as a number of types of items prepared as picking targets operate simultaneously in a state of being connected to a same network. Identification information is given to each display apparatus. A host controller may use this identification information to selectively transmit an instruction to a specific display apparatus. In addition, each display apparatus may include its own identification information in information to transmit to the host controller, to indicate a transmission source of this information to the host controller.",
