Abstract

A medium conveying apparatus includes an imaging device to image a medium and configured to move in a moving direction, a roller configured to move in the moving direction, on an upstream side of the imaging device, a conveyance guide provided with the imaging device to move the imaging device, wherein the conveyance guide includes a slope for coming into contact with the medium, an engaging member provided with the imaging device to move the imaging device, and a moving member to move the imaging device by engaging with the engaging member in conjunction with a movement of the roller. The engaging member and the moving member are configured to be separated at a distance from one another when the medium is not conveyed. The moving member moves the imaging device by engaging with the engaging member only when the medium has a thickness greater than the distance.

First claim

What is claimed is:

1. A medium conveying apparatus comprising:
an imaging device, arranged to be movable in a direction perpendicular to a medium conveying direction, for imaging a medium;
a roller arranged to be movable in the direction perpendicular to the medium conveying direction, on an upstream side of the imaging device in the medium conveying direction;
a conveyance guide including a slope for coming into contact with a medium;
an engaging member; and
a moving member provided on a shaft of the roller to move in conjunction with a movement of the roller and move the imaging device by engaging with the engaging member, wherein
the engaging member and the moving member are arranged to be separate from one another when a medium is not conveyed, and wherein the moving member moves the imaging device by engaging with the engaging member only when a medium with a predetermined thickness is conveyed.

2. The medium conveying apparatus according to claim 1 , wherein
the conveyance guide is integrally provided with the imaging device in such a way as to protrude toward the roller side, and
the conveyance guide moves the imaging device by the slope coming into contact with a medium.

3. The medium conveying apparatus according to claim 1 , wherein the engaging member is arranged in such a way that a distance separating the engaging member from the moving member when a medium is not conveyed is less than a distance between an upper end of the slope and a medium conveyance surface in the direction perpendicular to the medium conveying direction.

4. The medium conveying apparatus according to claim 1 , wherein the slope is arranged in such a way that a distance between an upper end of the slope and a medium conveyance surface is less than a distance between a rotation center of the roller and the medium conveyance surface in the direction perpendicular to the medium conveying direction.

5. The medium conveying apparatus according to claim 1 , wherein an end of the conveyance guide on the roller side is arranged more toward the imaging device side than a rotation axis of the roller in the medium conveying direction.

6. A medium conveying apparatus comprising:
an imaging device, arranged to be movable in a direction perpendicular to a medium conveying direction, for imaging a medium;
a roller arranged to be movable in the direction perpendicular to the medium conveying direction, on an upstream side of the imaging device in the medium conveying direction;
a conveyance guide including a slope for coming into contact with a medium;
an engaging member; and
a moving member for moving in conjunction with a movement of the roller and moving the imaging device by engaging with the engaging member, wherein
the engaging member and the moving member are arranged to be separate from one another when a medium is not conveyed, wherein the moving member moves the imaging device by engaging with the engaging member only when a medium with a predetermined thickness is conveyed, and wherein
the engaging member is arranged in such a way that a distance separating the engaging member from the moving member when a medium is not conveyed is less than a distance between an upper end of the slope and a medium conveyance surface in the direction perpendicular to the medium conveying direction.

7. A medium conveying apparatus comprising:
an imaging device, arranged to be movable in a direction perpendicular to a medium conveying direction, for imaging a medium;
a roller arranged to be movable in the direction perpendicular to the medium conveying direction, on an upstream side of the imaging device in the medium conveying direction;
a conveyance guide including a slope for coming into contact with a medium;
an engaging member; and
a moving member for moving in conjunction with a movement of the roller and moving the imaging device by engaging with the engaging member, wherein
the engaging member and the moving member are arranged to be separate from one another when a medium is not conveyed, wherein the moving member moves the imaging device by engaging with the engaging member only when a medium with a predetermined thickness is conveyed, and wherein
the slope is arranged in such a way that a distance between an upper end of the slope and a medium conveyance surface is less than a distance between a rotation center of the roller and the medium conveyance surface in the direction perpendicular to the medium conveying direction.
