Abstract: A lens sheet manufacturing method according to one aspect of the presently disclosed subject matter includes: conveying an original lens sheet having a plurality of linear lens elements arranged and formed in parallel with each other on a front sheet surface; detecting an edge line of one of the lens elements; determining whether the detected edge line and a trimming direction blade included in a punching blade are parallel with each other; when it is determined that they are not parallel with each other, controlling a conveying direction of the original lens sheet so that the trimming direction blade and the detected edge line are parallel with each other; and temporarily stopping conveying with the edge line of the lens element and the trimming direction blade being parallel with each other and punching the original lens sheet with the punching blade to manufacture a separated lens sheet.
