- a conveying device that conveys a booklet to a page turning position along a conveying path;
- upper and lower vacuum pads configured to be pressed against and to suck and hold upper and lower surfaces of the booklet conveyed to the page turning position by the conveying device;
- a drive device that moves the upper vacuum pad to raise, by a predetermined angle, a page of the booklet in a direction for opening the booklet about a stitch of the booklet;
- a contact roller unit that moves into a position below the page raised by the predetermined angle;
- and

- a drive device that moves the upper vacuum pad to raise, by a predetermined angle, a page of the booklet in a direction for opening the booklet, so that the page secondarily buckles in an S-shape, whereby the page is separated from the other pages;
- a contact roller unit that moves into a position below the page raised by the predetermined angle;
- a first control device that performs control, such that after the contact roller unit moves the position below the page, the upper and lower vacuum pads cancel sucking and holding the page, and then the booklet is conveyed, and thus the page is turned;
- a vacuum degree measurement device that measures the degree of vacuum of the upper vacuum pad when the page of the booklet is raised;
- and
- a second control device, wherein when the degree of vacuum measured by the vacuum degree measurement device is determined to be equal to or less than a predetermined value, the second control device determines that the page is detached from the upper vacuum pad, and retries page turning operation by causing the upper vacuum pad to suck and hold the page again so that the page is raised in such a manner that the amount of change of secondary buckling of the page is reduced.
