DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a binding device for filing papers, for example.

[0002]

2. Description of the Related Art Various types of binding devices for filing papers have been proposed. Conventionally, a binding device for binding perforated paper and a binding device for binding non-perforated paper have been proposed. Have different structures, each having a dedicated structure. For this reason, it is possible to bind perforated paper to a binding device that binds non-perforated paper, but in that case, binding is performed without using holes formed in paper in order to prevent dropouts and the like and securely bind. You can only be there and vice versa. On the other hand, in a binding device that binds a perforated sheet, a part of the binding device, for example, a binding pin or a binding foot is inserted into the hole to perform binding.

Generally speaking, paper without a binding hole cannot be bound with a binding device for binding paper with a binding hole. Paper with a binding hole can be bound with a binding device that can be bound without opening the binding hole.However, since a binding hole is not used, a binding foot or the like must be inserted into the binding hole. As compared with the binding method, the reliability of filing is inferior, and for example, dropout may occur. On the other hand, in a binding device having a structure for binding a sheet with a binding hole, it takes time to insert the binding foot of the binding device into the binding hole of the sheet.

Therefore, the main object of the present invention is not limited to either paper having a binding hole or paper having no binding hole, regardless of the type of paper, It is an object of the present invention to provide a binding device having a new structure capable of reliably binding using the binding holes and binding even paper having no binding holes.

Since the front end of the binding foot that is inserted into the through hole of the second holding portion and protrudes to the outside surface through the second holding portion is locked, the binding foot inserted into the binding hole of the paper can be formed without a complicated structure. Can be fixed.

According to the seventh aspect of the present invention, the binding foot is inserted into the binding hole formed in the paper sandwiched between the bases, so that the binding foot is located on one side of the base and on the other side of the base. Since the sheet is bent in the radial direction of the binding hole between the sheet and the located portion, the sheet is smoothly locked by the binding foot fixing means, so that the sheet with the binding hole can be bound.

According to the eighth aspect of the present invention, the binding foot fixing means has the binding foot locking recess formed at a position corresponding to the through hole of the second holding portion, so that the second holding portion has a through hole. The binding foot that is inserted into the hole and passes through it and protrudes to the outer surface of the second holding portion is locked, so that the binding foot inserted into the binding hole of the paper can be fixed without a complicated structure. it can.

According to the ninth aspect of the present invention, the binding foot locking recess of the binding foot fixing means is configured such that the tip of the binding foot is bent in the longitudinal direction of the base and the tip is formed on the outer surface of the second holding portion. Since it is formed in the longitudinal direction of the binding foot so as to press the binding foot, the tip of the binding foot protruding on the outer surface of the second holding portion is bent and locked, so that a complicated structure is not required. Also, the binding foot inserted into the binding hole of the paper can be fixed.

According to the tenth aspect of the present invention, the binding foot moving means and the binding foot fixing means are connected to the second holding portion of the base by the second holding portion.
Is connected by the connecting portion in the vicinity of the edge opposite to the front end of the holding portion, so that if the binding foot moving means is moved to move the binding foot, the binding foot fixing means also moves at the same time, so once The sheet can be bound or removed by the operation of.

According to the eleventh aspect of the present invention, the binding foot fixed with the fixing portion to the belt-like portion constituting the binding foot moving means accommodates the binding foot formed between the fixing portion and the surface of the base. Since the sheet is accommodated in the space, the binding foot can be very easily removed from the binding hole of the sheet.

According to the twelfth aspect of the present invention, the binding foot moving means is moved in the direction in which the binding feet are released, so that the binding foot is accommodated in the binding foot receiving space formed between the fixing portion and the base surface. Further, the bending restoring portion and the leading end locking portion of the binding foot are moved by the binding foot moving means in the inserting direction of the binding foot, so that the bending restoring portion and the leading end locking portion of the binding foot become the binding foot. Is inserted into the through hole of the first sandwiching portion from the accommodation space portion, and then protrudes toward the binding hole of the paper through the hole, is inserted into the through hole of the second sandwiching portion, and passes therethrough. Since the binding foot reaches the binding foot locking recess, the binding foot can be very easily removed from the binding hole of the sheet.
