Problems to be Solved by the Invention However, according to the conventional binder metal fittings described above, when all or a part of the loaded multi-hole paper is extracted for use or transferred to another binder metal fitting, the The paper fell apart,
When binding the paper into the binder metal fitting again, the binding holes must be aligned in the binding direction, and there are also inconveniences in handling, such as the need to close the binder metal fitting.

Means to Solve the Problem Therefore, the present application is configured so that the binder metal fittings can be automatically closed by the operation of closing the cover, and the extracted sheets can be kept in a bound state. , provides a binder metal fitting that is convenient to handle, and its gist is that a large number of binding rods and at least two
A mounting portion and an elastic contact piece extending outward facing the upper surface of the mounting portion are provided at an intermediate position of one longitudinal edge of the substrate on which the book binding tube is implanted, and the mounting portion is provided with:
An engagement plate having a restraining piece on its upper edge that restrains the upper surface of the pressing member, which will be described later, when standing up, is movably provided, and is brought into pressure contact with the elastic contact piece on the inner edge of the engagement plate, so that the engagement plate A binding member is provided with a bending piece that applies elasticity in the rising and falling directions with the dead point as a boundary, and a connecting rod that is inserted into and removed from the binding tube is protruded on the inner surface of the base plate that comes into contact with the tip of the binding rod. This is a binder metal fitting characterized in that it is constituted by a presser member provided therein.

Function: When loading paper, the engaging plate is rotated in the prone direction with the fingertips against the elastic contact piece that comes into pressure contact with the bent piece and presses the engaging plate in the upright direction. Then, the bent piece pushes up the elastic piece while drawing a circular arc, and when it crosses the dead point where its surface and the plane of the bent piece are at right angles, the elastic piece now urges the engagement plate in the downward direction. Since the bent piece is compressed so that
The engagement plate automatically lies down. After releasing the restraining state of the presser member in this way, lift the presser member and pull out the connecting rod from the binding tube.In this state, insert the binding hole of the paper into the binding rod, and insert the connecting rod into the binding tube again. Then, the upper end of the binding rod is covered with the substrate of the holding member, and then the engagement plate is raised against the elastic contact piece. Then, when the bent piece pushes up the elastic piece again while drawing a circular arc and crosses the aforementioned dead point,
This time, the elastic contact piece presses the bent piece so as to urge the engagement plate in the upright direction, so the engagement plate automatically stands up and maintains its upright state.

In addition, when removing some or all of the sheets from the stacked state, if the engagement plate is rotated in the direction of falling down against the elastic contact piece, the engagement plate will fall down, as mentioned above, and the paper will be removed. A part or all of the paper is pulled out from the stacking member together with the holding member, and the extracted paper is held by the connecting rod in the same way as in the stacked state, so there is no risk that the extracted paper will shift apart. Therefore, in this state, the binding hole of the paper can be inserted through the binding rod again and the paper can be bound.
