Abstract: An operation status display device displays an operation status of a board work machine, in which an operator replenishes an article to be used in production of a board product, and the operation status display device includes an acquisition section and a display section. The acquisition section is configured to acquire a first time, which is a wait time from when the article is insufficient in the board work machine to when the operator starts replenishment work of the article, and a second time, which is a work time from when the operator starts the replenishment work to when the article is replenished in the board work machine. The display section is configured to display the first time and the second time when the article is insufficient in the board work machine to when the article is replenished.

Abstract: An operation state display device displays an operation state of a board production facility in which a board is sequentially conveyed to multiple board work machines, which perform predetermined board work on the board, and the board work is sequentially performed to produce a board product, and includes an acquisition section and a display section. The acquisition section acquires an execution time zone in which setup changing work required for switching a type of the board product to be produced is performed, for each board work machine, based on production information acquired by the board production facility during production of the board product. The display section graphically displays at least one of the execution time zone for each of the multiple board work machines and the execution time zone for a predetermined board work machine of the board production facility in time series.

Abstract: A work management device manages a board work line having multiple board work machines for performing work on a board. The work management device includes a problem detection section configured to detect that a problem has occurred in any of the multiple board work machines; a handling method database configured to accumulate handling methods for problems; an updating section configured to update handling methods for problems at any time; and a work instruction section configured to extract and indicate to an operator a handling method for a problem from the handling method database when the problem detection section detects that the problem has occurred.

Abstract: An ignitor assembly for oil stoves is disclosed which includes an ignitor plug held in alignment with an exposed portion of a wick for firing the wick through the utilization of discharge originated from the ignitor plug. A light-sensitive element is disposed at a predetermined distance from the ignitor plug and in alignment with the exposed portion of the wick.
