Abstract
A stapler of the present invention includes a retaining part having a staple pusher, a storing section that stores a staple, and a receiving base that bends leg parts after piercing the staple pushed out by the staple pusher through a sheet material to bind the sheet material with the staple. The staple includes left and right shoulder parts against which the staple pusher abuts, leg parts extending substantially perpendicularly from the shoulder parts and a pattern part having an arbitrary shape and provided between the left and right shoulder parts. The pattern part is inclined against the leg parts and the storing section is provided, on one side thereof, with a take-out opening of the staple that is large enough to allow the pattern part to pass.
Claims22
An apparatus comprising:
- a stapler having a staple pusher;
- a cartridge attached to a storing section of said stapler, said cartridge including:
- a take-out opening;
- a guide groove part for guiding a staple toward said take-out opening;
- a spring for urging said staple in said cartridge toward said take-out opening;
- and
- an insertion hole formed on an upper portion of said take-out opening to allow said staple pusher to be inserted into said cartridge;
- and
- said staple being accommodated in said cartridge and having:
- a right shoulder part and a left shoulder part against which said staple pusher is to abut;
- leg parts extending substantially perpendicularly from said shoulder parts;
- and
- an arbitrarily-shaped pattern part located between said right shoulder part and said left shoulder part and being inclined with respect to said leg parts, a thickness of said pattern part being smaller than a width of each of said leg parts;
- wherein said guide groove part is shaped and arranged to guide lower ends of said leg parts toward said take-out opening.
An apparatus comprising:
- a retaining part including a staple pusher;
- a storing section for storing staples and having a take-out opening, said staples being arranged in said storing section so that lower ends of multiple adjacent staples are located on a substantially horizontal plane;
- and
- a receiving base;
- each of said staples having:
- a right shoulder part and a left shoulder part against which said staple pusher is to abut;
- leg parts extending substantially perpendicularly from said shoulder parts;
- and
- an arbitrarily-shaped pattern part located between said right shoulder part and said left shoulder part and being inclined with respect to said leg parts, a thickness of said pattern part being smaller than a width of each of said leg parts;
- wherein said receiving base is shaped and arranged to bend said leg parts after said leg parts are pierced through sheet materials when pushed by said staple pusher;
- and
- wherein said take-out opening is sized to allow said pattern part of each of said staples to pass therethrough.
A staple comprising:
- a right shoulder part and a left shoulder part against which a staple pusher is to abut;
- leg parts extending substantially perpendicularly from said shoulder parts;
- and
- an arbitrarily-shaped pattern part located between said right shoulder part and said left shoulder part and being inclined with respect to said leg parts, a thickness of said pattern part being smaller than a width of each of said leg parts.
