A medium conveyance device includes a first separator that separates a first medium from a plurality of mediums, a processor that processes the first medium and sends the processed first medium as a second medium, a second separator that when a non-separation mode is set, conveys the second medium to a next processor, and when a separation mode is set, conveys a third medium, which is separated from the second medium, to the next processor, and a controller that switches between the non-separation mode and the separation mode based on information obtained as a result of processing the first medium.

A method for transferring graphene according to an exemplary embodiment of the present invention includes a process of transferring graphene of a metal sheet onto a thermal release film in each vacuum chamber and a process of transferring the graphene of the thermal release film onto a base material substrate. According to the method for transferring graphene, adhesion is increased by removing bubbles or foreign substances at the time of transferring the graphene to prevent separation of the graphene at the time of etching a metal substrate and enhance an adhesive quality state of the graphene on a target substrate.

A hand tool is provided for removing a secondary liner from a tape carrier of a two-sided adhesive tape where the opposing primary side of the tape carrier is attached to a surface. The hand tool includes a handle. One end of the handle may include a handle fulcrum depending from the handle. A plurality of sharp points together define a mathematical line. The plurality of sharp points also define point axes which together define a mathematical plane. The mathematical line is coincident with the mathematical plane. The mathematical plane defines an acute angle with respect to the handle and to the handle fulcrum.
