Sheet adjusting device, sheet holding receptacle incorporating same, and image forming apparatus incorporating same

A sheet adjusting device, comprising:

• a sheet setting plate to set a sheet thereon;
• a first regulating member disposed on the sheet setting plate, the first regulating member configured to move in a sheet conveyance direction along the sheet setting plate, the first regulating member regulating a trailing end portion of the sheet set on the sheet setting plate in the sheet conveyance direction to adjust a position of the trailing end of the sheet in the sheet conveyance direction;
• a second regulating member facing the first regulating member, the second regulating member configured to regulate a leading end of the sheet in the sheet conveyance direction to adjust a position of the leading end of the sheet in the sheet conveyance direction to a position by which the leading end of the sheet moved by the first regulating member abuts against the second regulating member in the sheet conveyance direction;
• a drive transmission mechanism configured to transmit a driving power generated by a driving power source to the first regulating member to move the first regulating member in the sheet conveyance direction;
• a stopping unit configured to stop the first regulating member that is moving on the sheet setting plate toward the sheet either when a load exceeding a threshold is given to either the driving power source or the drive transmission mechanism or when a pressure exceeding the threshold is given to at least one of the first regulating member and the second regulating member;
• and
• a pressure detecting unit configured to detect pressure on at least one of the first regulating member and the second regulating member, the stopping unit configured to cause the driving power source to stop driving when detection results obtained by the pressure detecting unit exceed the threshold,
• wherein the pressure detecting unit includes a first pressure detector to detect pressure on the first regulating member and a second pressure detector to detect pressure on the second regulating member,
• the stopping unit causing the driving power source to stop driving when both detection results obtained by the first pressure detector and by the second pressure detector exceed the threshold.
