Abstract
On the one surface of a back plate suited to a length-and-width size of a ring binder, hooks serving as an engaging means are formed. The back plate is fixed to the spine surface of the file cover. When the ring binder is pressed against the back plate, the hooks are engaged with the ring binder so that the file cover is mounted on a booklet bound with the ring binder.
