Image Scanning Device

Abstract

An image scanning device includes: a main body that has a box-shaped appearance having a front face and a back face; a flat bed scanner unit that is mounted on the main body to be rotatable around an axis provided near the back face along a width direction of the main body; and a stopper that supports the flat bed scanner unit in an opened state. The stopper includes: a base end that is rotatably attached to an upper portion of the main body; and a leading end that is slidably attached to the flat bed scanner unit. A casing of the flat bed scanner is provided with a stopper accommodating portion that is recessed from a bottom surface of the casing. The stopper accommodating portion accommodates the stopper above the bottom surface in a closed state where the flat bed scanner unit is closed.

Claims

1. An image scanning device comprising; a main body that has a box-shaped appearance having a front face and a back face that opposes to the front face;a flat bed scanner unit that is mounted on the main body to be rotatable around an axis provided near the back face along a width direction of the main body, the flat bed scanner unit being provided with a casing and an image sensor that moves in the width direction to scan an image of a document placed on a scanning area; anda stopper that supports the flat bed scanner unit in an opened state where the flat bed scanner unit is opened with respect to the main body by being rotated around the axis, the stopper having: a base end that is rotatably attached to an upper portion of the main body; anda leading end that is slidably attached to the flat bed scanner unit,wherein the casing is provided with a stopper accommodating portion that is recessed from a bottom surface of the casing, the stopper accommodating portion accommodating the stopper above the bottom surface in a closed state where the flat bed scanner unit is closed with respect to the main body.

2. The image scanning device according to claim 1, wherein the stopper is disposed to extend in a depth direction of the main body, with the base end positioned near to the front face and the leading end positioned near to the back face.

3. The image scanning device according to claim 1, wherein the stopper accommodating portion accommodates the stopper at a height where the image sensor is disposed.

4. The image scanning device according to claim 1, wherein the stopper is provided with a friction member that is disposed at the leading end, the friction member being configured to move inside and along the stopper accommodating portion, and wherein the stopper accommodating portion is provided with a friction adjusting member that changes in posture into a first posture and a second posture, the first posture being in a pressure contact with the friction member to apply a sliding friction to the friction member, the second posture being in non-pressure contact with the friction member to allow the friction member to move without the sliding friction.

5. The image scanning device according to claim 4, wherein the friction adjusting member changes into the second posture when the flat bed scanner unit opens with respect to the main body, and wherein the friction adjusting member changes into the first posture when the flat bed scanner unit closes with respect to the main body.

6. The image scanning device according to claim 5, wherein the friction adjusting member is provided with: a pressure contact portion that pressure contacts with the friction members the pressure contact portion being provided in the stopper accommodating portion to be projectable therefrom; anda guide groove formed along a direction that the stopper slides,wherein the stopper is engaged at the leading end with the guide groove,wherein the stopper allows the friction adjusting member to project from the stopper accommodating portion when the flat bed scanner unit opens with respect to the main body, andwherein the stopper allows the friction adjusting member to be accommodated into the stopper accommodating portion when the flat bed scanner unit closes with respect to the main body.

7. The image scanning device according to claim 1, wherein the stopper is formed in a flat shape being broad in a height direction of the main body.

8. The image scanning device according to claim 7, wherein the stopper is provided with a rib that is formed by expanding a bottom face of the stopper.

9. The image scanning device according to claim 7, wherein the stopper is provided with a reinforcing portion that projects in a thickness direction of the stopper.

10. The image scanning device according to claim 9, wherein the reinforcing portion is provided on both of a front face and a back face of the stopper to project alternately from the front face and back face in a thickness direction of the stopper.

11. The image scanning device according to claim 10, wherein the reinforcing portion projects from both of the front face and the back face at an area part of the stopper.

12. The image scanning device according to claim 1, wherein the main body is provided therein with a printer unit that form an image on a sheet.
