| Claim: | 1. A sheet conveying device comprising: a sheet stacker to stack sheets; an air blower to blow air to the sheets; a guide to face an uppermost sheet on the sheet stacker; and a receiving portion to which the guide is attached, wherein a set height of a contact portion of the guide to contact the uppermost sheet is changeable, wherein an attachment position of the guide is changeable to change the set height, wherein the receiving portion includes a plurality of attachment positions at which the set height of the contact portion is changeable, wherein the set height of the contact portion is different between adjacent ones of the plurality of attachment positions. |
| Claim: | 2. The sheet conveying device according to claim 1 , wherein the plurality of attachment positions are groove-shaped portions having different depths. |
| Claim: | 3. The sheet conveying device according to claim 2 , wherein grooves of the groove-shaped portions are triangular or semicircular in cross section. |
| Claim: | 4. The sheet conveying device according to claim 1 , wherein the contact portion of the guide has a linear shape extending in a sheet conveyance direction. |
| Claim: | 5. The sheet conveying device according to claim 4 , wherein the guide includes a wire extending in the sheet conveyance direction. |
| Claim: | 6. The sheet conveying device according to claim 1 , further comprising: a plurality of guides including the guide and each extending in a sheet conveyance direction; and a support supporting both ends of the plurality of guides in the sheet conveyance direction such that the plurality of guides are rotatable about a virtual axis extending along the sheet conveyance direction, wherein the support and lower end portions of adjacent ones of the plurality of guides are connectable to change the set height of the contact portion. |
| Claim: | 7. An image forming system comprising: the sheet conveying device according to claim 1 ; and an image forming apparatus to form an image on a sheet, wherein the sheet conveying device and the image forming apparatus are integrated as a single unit or coupled as separate units. |
