Abstract

A transfer method is provided and includes a disposing step of disposing a transfer sheet and a medium in an inside of a sealed space formed by using a pressure welding sheet having flexibility in at least one part; a pressure welding step of suctioning the inside of the sealed space by a negative pressure and pressure welding the pressure welding sheet and the medium by the negative pressure to closely attach the transfer sheet and the medium; an irradiating step of softening an adhesive layer of the transfer sheet by irradiation of a light ray in a state in which the transfer sheet is closely attached to the medium by the pressure welding sheet and adhering the adhesive layer to the medium by a pressure welding force from the pressure welding sheet; and a peeling step of peeling off the transfer sheet from the medium after the irradiating step.

First claim

What is claimed is:

1 . A transfer method comprising:
a disposing step of disposing a transfer sheet and a medium in an inside of a sealed space, wherein the sealed space is formed by using a pressure welding sheet having flexibility in at least one part, and the transfer sheet and the medium are disposed so that an adhesive layer of the transfer sheet and a transfer layer of the transfer sheet are layered, and the adhesive layer has a thermally melting property, and the adhesive layer is contacted with the medium; a pressure welding step of suctioning the inside of the sealed space by a negative pressure and pressure welding the pressure welding sheet and the medium by the negative pressure to closely attach the transfer sheet and the medium; an irradiating step of softening the adhesive layer by irradiation of a light ray generated from a light source in a state in which the transfer sheet is closely attached to the medium by the pressure welding sheet and adhering the adhesive layer to the medium by a pressure welding force from the pressure welding sheet; and a peeling step of peeling off the transfer sheet from the medium after the irradiating step.

2 . The transfer method according to claim 1 , wherein
the pressure welding sheet is formed of a member that transmits the light ray, and in the irradiating step, the light ray is incident from a side of the transfer sheet.

3 . The transfer method according to claim 2 , wherein
the transfer layer is formed of a metal foil layer, and in the irradiating step, the adhesive layer is thermally melted when a heat generating layer disposed on a front side in an incident direction of the light ray in the metal foil layer generates heat by the light ray.

4 . The transfer method according to claim 3 , wherein
the heat generating layer is formed on the pressure welding sheet.

5 . The transfer method according to claim 1 , wherein the pressure welding step includes:
accommodating the medium and the transfer sheet in an inside of a bag body formed by using the pressure welding sheet; and generating the negative pressure between the pressure welding sheet and the medium by suctioning the inside of the bag body.

6 . The transfer method according to claim 5 , further comprising:
a mounting step of mounting the medium on a mounting portion of a jig formed with the mounting portion for mounting the medium, wherein in the pressure welding step, the inside of the sealed space is suctioned by the negative pressure, and the pressure welding sheet and the jig are pressure welded by the negative pressure to closely attach the transfer sheet and the medium.

7 . The transfer method according to claim 1 , wherein
in the disposing step, the transfer sheet and the medium are accommodated inside a cup-shaped container from an opening portion of the cup-shaped container having the opening portion in which an upper surface side is opened, and the sealed space is formed by closing the opening portion of the cup-shaped container with a closing member in which at least one part is made of the pressure welding sheet.

8 . The transfer method according to claim 2 , wherein the pressure welding step includes:
accommodating the medium and the transfer sheet in an inside of a bag body formed by using the pressure welding sheet; and generating the negative pressure between the pressure welding sheet and the medium by suctioning the inside of the bag body.

9 . The transfer method according to claim 3 , wherein the pressure welding step includes:
accommodating the medium and the transfer sheet in an inside of a bag body formed by using the pressure welding sheet; and generating the negative pressure between the pressure welding sheet and the medium by suctioning the inside of the bag body.

10 . The transfer method according to claim 4 , wherein the pressure welding step includes:
accommodating the medium and the transfer sheet in an inside of a bag body formed by using the pressure welding sheet; and generating the negative pressure between the pressure welding sheet and the medium by suctioning the inside of the bag body.
