When the elastic slider is slid in a direction away from one side of the substrate, in Rukoto the second flat plate portion by the elastic force of the elastic slider is pressed, opposite to the direction toward the first flat plate portion on the substrate The document clip according to claim 1 , wherein a force acting in a direction is applied, and the first flat plate portion is formed so as to move away from the substrate by turning about the hinge . A document sandwiching device in which a document placed on a substrate is sandwiched between a substrate and a document holding unit by elastic force of an elastic slider acting on a document holding unit provided on at least one side of the substrate,
The document holding unit has a protrusion that is attached to the substrate and protrudes from a surface in contact with the substrate.
The protrusion projects through the hole provided in the substrate and protrudes to the surface opposite to the surface of the substrate where the document holding portion is attached,
The elastic slider is flexible, has a substantially U-shaped cross section, and sandwiches the document holder and the substrate together with the document holder attached to the substrate. Formed so as to be slidable in a direction substantially orthogonal to one side of the substrate while being in contact with the holding portion and the opposite surface,
The elastic slider is
In a state in which the document holding unit and the substrate are sandwiched together, the surface on the opposite side of the surface in contact with the document holding unit has a pair of notches on both sides parallel to the sliding direction,
The protruding portion passes through the hole portion provided in the substrate, and is positioned so that the notched portion and the protruding portion are close to each other when the elastic slider slides.
At the end of the protrusion, a flange protruding laterally from the protrusion is formed,
The collar portion is a document clip that is in contact with a part of the surface on the opposite surface side of the elastic slider.
