WIPO Patent Application WO/2012/114564

A1

[Problem] To provide a binder configured so that, in order to facilitate the replacement of leaves, binding pins can be easily opened and closed. [Solution] This binder (10) is provided with: binding pin sections (12); connection regions for connecting the binding pin sections; and an axial connection section (16) serving as the center axis about which binding pins composing the binding pin sections are opened and closed. The binding pins (20, 30) composing the binding pin sections are provided in pairs to pairs of the connection regions, respectively, at appropriate intervals in the longitudinal direction of the connection regions so as to protrude from the connection regions in such a manner that each pair of the binding pins (20, 30) face each other. A pressing section (140) is provided in a region at one end or in regions at both ends in the direction in which the center axis, about which the binding pins are opened and closed, extends. The pressing section is configured so that, in order to disengage one of each facing pair of the binding pins from the engagement section of the other of the facing pair of the binding pins, the pressing section is displaced in the direction in which the center axis extends.
