Abstract

A transfer device 5 transfers a fine transfer pattern M 1 formed on a mold M to a molding target W. The transfer device includes: a base member 47 including a press body 31; a moving member 49 including a molding target placing body 33 that sandwiches and presses the mold M and the molding target W in cooperation with the press body 31 , and is provided on the base member 47 so that the molding target placing body 33 can move; and a moving body supporting body 51 that includes a guide portion 71 , and is engaged with and provided integrally on the base member 47 only in a region of the base member 47 elastically deformed very slightly by reaction force when the press is performed, the region being a region where a flexure angle becomes substantially “0”.

First claim

The invention claimed is:

1. A transfer device for transferring a fine transfer pattern formed on a mold to a molding target, the transfer device comprising:
a base member including a first press portion;
a moving member including a second press portion, the second press portion sandwiching and pressing the mold and the molding target in cooperation with the first press portion, and the second press portion being provided on the base member so as to move in a direction of approaching or leaving the first press portion; and
a supporting body including a guide portion guiding the movement of the moving member, the supporting body being engaged with the base member only in a region of the base member elastically deformed very slightly by reaction force when the press is performed, the region being a region where a flexure angle by the elastic deformation becomes substantially “0”, and the supporting body being provided integrally on the base member.

2. A transfer device for transferring a fine transfer pattern formed on a mold to a molding target, the transfer device comprising:
a base member formed integrally by including a first member having a first press portion, a second member spaced apart from the first member on a side on which the first press portion is provided, and a coupling member that couples the first member and the second member to each other;
a third member movable in a direction of connecting the first member and the second member to each other, the third member including a second press portion provided between the first member and the second member and opposite to the first press portion, the second press portion sandwiching and pressing the mold and the molding target in cooperation with the first press portion of the first member by a movement of the third member to the first member side; and
a supporting body including a guide portion in a part thereof, the guide portion being configured to guide the movement of the moving body, the supporting body being engaged with only a region of the second member at the other part thereof to be provided integrally on the second member, the region of the second member being a region of a center of reaction force generated when moving the third member and pressing the mold and the molding target by the respective press portions, or a region in a vicinity of the center, or the region of the center and the region of the vicinity of the center.

3. The transfer device according to claim 2 ,
wherein the first member, the second member and the third member are formed into flat shapes, a thickness direction of each of the first, second and third members coincide with others, the third member is located between the first member and the second member, the first member and the second member overlap each other when viewed from the thickness direction, a center of the first member, a center of the second member and a center of the third member coincide with one another when viewed from the thickness direction,
when viewed from the thickness direction, the coupling member is arranged symmetrically with respect to the centers of the first member and the second member in vicinities of peripheries of the first member and the second member,
the first press portion protrudes to the third member side from a flat surface of the first member, the flat surface being opposite to the third member, and a tip end surface of the first press portion is parallel to the flat surface of the first member, the flat surface being opposite to the third member,
the second press portion protrudes to the first member side from a flat surface of the third member, the flat surface being opposite to the first member, and a tip end surface of the second press portion is parallel to the flat surface of the third member, the flat surface being opposite to the first member,
when viewed from the thickness direction, a center of the tip end surface of the first press portion, a center of the tip end surface of the second press portion, and the center of the first member coincide with one another,
the press is configured to be performed by applying force of moving the third member away from the second member to the second member and the third member,
a direction of reaction force to be generated in the first member when the press is performed is the thickness direction of the first member, the thickness direction being a direction of leaving the second member,
a direction of reaction force to be generated in the second member when the press is performed is the thickness direction of the second member, the thickness direction being a direction of leaving the first member,
when viewed from the thickness direction, centers of the respective reaction forces coincide with the centers of the first member and the second member, and
the supporting body is engaged with the second member only in a vicinity of the center of the second member, and is provided integrally on the second member.

4. A transfer device for transferring a fine transfer pattern formed on a mold to a molding target, the transfer device comprising:
a base member formed integrally by including a first member having a first press portion, a second member spaced apart from the first member on a side on which the first press portion is provided, and a coupling member that couples the first member and the second member to each other;
a third member movable in a direction of connecting the first member and the second member to each other, the third member including a second press portion provided between the first member and the second member and opposite to the first press portion, the second press portion sandwiching and pressing the mold and the molding target in cooperation with the first press portion of the first member by a movement of the third member to the first member side; and
a supporting body including a guide portion in a part thereof,

the guide portion being configured to guide the movement of the moving body, the supporting body being engaged with only a region of the first member at the other part thereof to be provided integrally on the first member, the region of the first member being a region of a center of reaction force generated when moving the third member and pressing the mold and the molding target by the respective press portions, or a region in a vicinity of the center, or the region of the center and the region of the vicinity of the center.

5. The transfer device according to claim 4 ,
wherein the first member, the second member and the third member are formed into flat shapes, a thickness direction of each of the first, second and third members coincide with others, the third member is located between the first member and the second member, the first member and the second member overlap each other when viewed from the thickness direction, a center of the first member, a center of the second member and a center of the third member coincide with one another when viewed from the thickness direction,
when viewed from the thickness direction, the coupling member is arranged symmetrically with respect to the centers of the first member and the second member in vicinities of peripheries of the first member and the second member,
