Abstract

A page-turning device turning a page of a book includes a turning unit and a blower. The turning unit holds the page at a departure position of the page of the book being opened and releases the holding of the page at a destination position of the page. The blower sends air above the page at the departure position to blow against the page at the destination position.

Claims

1. A method for turning a page of an opened book, the method comprising:

supporting the book with a support base such that (i) a page to be turned is horizontal at a departure position, and (ii) the page forms a predetermined angle with a horizontal plane at a destination position;

sticking an adhesive component to the page horizontally supported at the departure position;

turning the page at the departure position with the adhesive component toward the destination position;

sending air above the opened book with a blower toward the destination position from the departure position against the page being turned at the destination position; and

imaging a page which is to be turned next and is horizontally supported at the departure position, while air from the blower is blown against the page forming the predetermined angle with the horizontal plane at the destination position.

2. The method according to claim 1, further comprising adjusting an air volume of the blower.

3. The method according to claim 2, further comprising:

detecting an amount of pages turned by the adhesive component,

wherein the adjusting adjusts the air volume of the blower based on the detected amount of pages.

4. The method according to claim 3, wherein the adjusting adjusts the air volume of the blower such that when the detected amount of pages is large, the air volume of the blower is adjusted to be larger than when the detected amount of pages is small.

5. The method according to claim 1, further comprising adjusting a moving direction of air from the blower.

6. The method according to claim 5, further comprising:

detecting an amount of pages turned by the adhesive component,

wherein the adjusting adjusts the moving direction of the air from the blower based on the detected amount of pages.

7. The method according to claim 6, wherein the adjusting adjusts the moving direction of the air from the blower when the detected amount of pages is large to be lowered with respect to the moving direction of the air from the blower when the detected amount of pages is small.

8. The method according to claim 1, wherein the page being turned is separated from the adhesive component by the blower sending air above the opened book and blowing against the page being turned.

9. The method according to claim 1, wherein the predetermined angle is in a range of 30 to 45 degrees.
