Apparatus and method is provided for simulating behavior of a flexible medium for a plurality of times under different conditions. A component inside the conveyance path is displayed together with a plurality of locations in which abnormal behavior of the flexible medium has occurred based on a result of the simulation.

A paper aligning mechanism and an image generating device having the same are provided, the paper aligning mechanism is arranged on a calibration path of the image generating device, the calibration path is arranged between a paper assigning mechanism and a paper-feeding mechanism of the image generating device, and the paper aligning mechanism has at least two calibrating swingarms arranged spacedly. Each of the calibrating swingarms has an arm portion and a pivoting axle portion arranged on the arm portion to pivotally connect the arm portion to the image generating device. The arm portion has an extending segment and a limiting segment extended from the extending segment, the limiting segment is downward extended along the calibration path toward an exit of the calibration path to be swingable and to block the exit of the calibration path.

A recording device includes a recording unit configured to discharge liquid onto a medium to perform recording, a transport unit configured to transport the medium at a position facing the recording unit, a transport unit downstream roller pair located downstream the transport unit in a medium transport path and configured to transport the medium, a restricting roller being a roller configured to restrict movement of a medium back end region upstream the transport unit downstream roller pair in the medium transport path toward the recording unit side, and including a plurality of teeth along an outer periphery thereof, and a guide member being a member configured to support the restricting roller, and guiding the medium.

An image forming apparatus includes a developing device, a plurality of feeding and delivering paths through which a printing medium is delivered to the developing device, a feeding roller unit which forms a developing and delivering path in which the plurality of feeding and delivering paths are joined and delivers the printing medium to the developing device, and a guide unit which guides the printing medium passing through the plurality of feeding and delivering paths to the feeding roller unit and is rotatably provided to expose the plurality of feeding and delivering paths to the outside. In the above configuration, the printing medium jam problems inside the image forming apparatus are easily cleared.

An image forming apparatus includes a casing; a process unit for forming a developer image on a sheet; an image exposing unit; a sheet cassette detachably mounted to the casing; a feeding roller for single the sheet from the cassette; a feeding guide provided in the casing and configured to guide the sheet moving from the cassette to the process unit. The exposing unit is disposed right above the feeding roller. The process unit is at a position the same position as the exposing unit in the vertical direction and downstream of the exposing unit in a horizontal direction. The cassette is below the feeding roller. The guide is between the exposing unit and the cassette in the vertical direction. The guide includes upper and lower guides. When the cassette is drawn out of the casing, the lower guide moves to an accommodating portion in the cassette.

A sheet conveying device includes a first conveyance roller, a sheet conveyance path, a second conveyance roller, and a pair of bearing portions. The first conveyance roller is provided in an apparatus main body. The sheet conveyance path has a guide surface that guides a sheet member in a sheet conveyance direction. The second conveyance roller is rotatably attached to the guide surface via a shaft and abuts on the first conveyance roller by a predetermined pressing force. The bearing portions are provided on the guide surface and support the shaft. Each bearing portion includes a concave groove portion and a bush member. The concave groove portion is formed on the guide surface such that a groove depth direction is perpendicular to the guide surface. The bush member is attached to the concave groove portion so as to be slidable in the groove depth direction and support the shaft.
