摘要:
The thin film transistor of this invention is formed on a substrate and includes an active layer and a first insulating film and a second insulating film sandwiching the active layer, wherein the overall polarity of fixed charges contained in the first insulating film is the reverse of the overall polarity of fixed charges contained in the second insulating film.
摘要:
A sheet carrying unit, which comprises double feed detecting means for detecting double feed of sheets and stopping means for stopping carrying of a sheet based on detection result of the double feed detecting means, comprising accepting means for accepting a type of a sheet to be carried, wherein the stopping means is constructed to stop carrying a sheet based on the type of sheet accepted by the accepting means and detection result of the double feed detecting means.
摘要:
Based on the type of sheet and the detection result of double feed, carrying a sheet is stopped. Carrying of a predetermined type of sheet is not stopped even when double feed is detected. The predetermined type of sheet is a sheet having air space inside thereof (an envelope, an OHP sheet, Kent paper, or the like).
