A button making device for making a button having a rear cover and a front cover, comprising:

• a base;
• a pressed mold arranged on an upper surface of said base;
• a pressing mold for making the button by engaging with said pressed mold;
• and
• a pressing shaft for causing said pressing mold to move so as to engage with said pressed mold;
• wherein
• said pressing shaft has a male threaded section capable of moving in an axial direction by being screwed into a female threaded section provided in a fixed member fixed above said base, and
• said male threaded section is formed so that before said pressing shaft moves upwards and said pressing mold comes into contact with said fixed member, said pressing shaft slackens off by moving away from said female threaded section of said fixed member.

A button making device for making a button having a rear cover and a front cover, comprising:

• a base;
• a pressed mold arranged on an upper surface of said base;
• a fixed member fixed to an upper part of said base;
• a pressing shaft having a male threaded section capable of moving in an axial direction by being screwed into a female threaded section provided in said fixed member, a pressing mold, provided at a lower end of said pressing shaft, for making the button by engaging with said pressed mold;
• and
• an operation means for causing said pressing shaft to move in an axial direction,
• further comprising a clutch for transmitting an operational force applied to said operation means to said pressing shaft provided between said operation means and said pressing shaft,
• wherein
• said clutch causes said operation means to slip with respect to said pressing shaft if an operational force greater than a specified value is applied to said operation means.

A button making device for making a button by fitting a first rear cover and a first front cover together, comprising:

• a base;
• a sliding platform movably attached to said base;
• a first attachment member connecting a first front cover mounting mold suitable for mounting said first front cover and a first rear cover mounting mold suitable for mounting said first rear cover;
• and
• an attachment means for removably attaching said first attachment member to said sliding platform;
• wherein
• said first front cover mounting mold and said first rear cover mounting mold slide along with said sliding platform and move to a button making position by turns by having said attachment means attach said first attachment member to said sliding platform so that the button can be produced.

A polygonal button comprising a front cover and a rear cover,

• said front cover having a polygonal front surface plate and a peripheral edge extending downward from said front surface plate,
• said peripheral edge comprising straight line sections and curved corner sections connecting said straight line sections,
• said rear cover having a polygonal rear surface plate and a peripheral edge extending upward from said rear surface plate,
• said peripheral edge comprising straight line sections and curved corner sections which connect said straight line sections,
• wherein
• said front cover is attached to said rear cover with said corner section of said peripheral edge held fast to said corner section of said peripheral edge of said rear cover.

A polygonal button comprising a front cover, a rear cover, and a sheet body,

• said front cover having a polygonal front surface plate and a peripheral edge extending downward from said front surface plate,
• said peripheral edge comprising straight line sections and curved corner sections connecting said straight line sections,
• said sheet body placed on said front surface plate of said front cover,
• said rear cover having a polygonal rear surface plate and a peripheral edge extending upward from said rear surface plate,
• said peripheral edge comprising straight line sections and curved corner sections which connect said straight line sections,
• wherein
• said front cover is attached to said rear cover with said corner sections of said peripheral edge held fast to said corner sections of said peripheral edge of said rear cover, and a peripheral edge of said sheet body is gripped by said peripheral edge of said front cover and said peripheral edge of said rear cover.

A method of mounting a pressing mold of a button making device having:

• a base;
• a sliding platform provided on an upper surface of said base capable of reciprocating;
• a first pressed mold suitable for mounting said front cover and a second pressed mold suitable for mounting said rear cover, arranged at both ends of said sliding platform;
• a pressing mold for making the button by independently engaging with each of said first pressed mold and said second pressed mold;
• a pressing shaft which is positioned at an upper side of said sliding platform, has a joining means for joining with said pressing mold formed at a lower end, and is capable of moving close to or away from said sliding platform by reciprocating in an axial direction;
• an operation means for causing said pressing shaft to reciprocate in the axial direction;
• and
• a cover which prevents a hand from reaching substantially right below said pressing shaft;
• said method comprising:
• a step of mounting said pressing mold to either one of said pressed molds;
• a step of causing said pressing mold and said pressed mold on which said pressing mold is mounted to move to substantially right below said pressing shaft by sliding said sliding platform;
• and
• a step of joining said pressing mold with a lower end of said pressing shaft by said joining means, by operating said operation means and bringing said lower end of said pressing shaft close to said sliding platform.
