Claims

[Scope of Claim for Utility Model Registration] (1) In a copying machine/enlarging machine that has a device for temporarily fixing paper at a predetermined exposure position, a base plate member that supports the paper face-to-face in the surface direction, and a base plate member that supports the paper in the width direction of the paper. a pair of first and second guide members disposed on the left and right that guide and regulate the paper; a first drive mechanism that selectively moves the first and second guide members according to the width dimension of the paper; a positioning member that regulates the position of the leading edge of the paper in the traveling direction; and a position where the positioning member faces the paper running area on the base plate in response to movement and fixing operations of the paper, and a position where the positioning member is retracted. A paper positioning device comprising: a second drive mechanism for moving the paper; and a second drive mechanism for moving the paper. (2) The first drive mechanism includes a flexible wire member, a drive source (motor), and movement of each part of the wire member in the width direction of the sheet relative to being driven in the same direction by the drive source. and a direction changing member that converts the wire member into two sets that run in opposite directions in a direction parallel to the wire member. A first set including a part that moves in the same direction as the one end at the other end is connected to the first guide member, and a part that moves in the same direction as the other end at one end from the other end and the winding part thereof. A second set of moving parts that moves in a direction opposite to the first set is connected to the second guide member, and the first and second guides are connected to each other according to the rotational direction of the drive source. The paper positioning device according to claim 1, wherein the members are moved toward and away from each other in the width direction. (3) The second drive mechanism has a drive shaft connected to a drive source at one end and capable of linearly reciprocating motion, and a drive shaft that is approximately L-shaped and rotatably supported at the center. and a connecting member connected at one end to the positioning member and at the other end to the drive shaft through a relationship between a pin and a long groove, respectively. A paper positioning device according to scope 1.
