The present invention is a keyboard having a touch mode and a character mode. The array substrate includes, on an insulating substrate, a switching element which is disposed in association with each of pixels, a pixel electrode which is connected to the switching element, and a common electrode which is separated from the pixel electrode and is common to the pixels. Such influence is accomplished partly by production in adjacent wells, partly by injection at low rate without fracturing in the well in which the fracture is to originate. The inline feeder further includes a feeder unit configured to separate groups of products from the contiguous supply of products in the product input line and move the group of products into the packaging line, each of the separated groups of products including a predetermined number of products from the product input line.
