An image forming apparatus includes a moving unit and a lifting and lowering mechanism. The moving unit is supported by a casing in an upwardly and downwardly moving manner. A fixed pully and a winding pully are provided in the casing. A movable pulley is provided in the moving unit. A wire is configured to be wound around the fixed pulley and the movable pulley. One end of the wire is fixed to the casing and the other end of the wire is fixed to the winding pulley. A rack is provided in the casing along an upper-and-lower direction. A pinion is provided in the moving unit and configured to be engaged with the rack. The winding pulley is rotated to wind and unwind the wire via the fixed pulley and the movable pulley, and the moving unit is lifted and lowered while the pinion being engaged with the rack.

The image forming apparatus includes a moving unit, a movable connector, a fixed connector, a wire, a fixed wire guide and a movable wire guide. The moving unit is supported by a casing in an upwardly and downwardly moving manner. The movable connector is provided in the moving unit. The fixed connector is provided in the casing. Both ends of the wire are connected to the movable connector and the fixed connector. The wire has a length longer than a distance between the movable connector and the fixed connector at lifting of the moving unit. The fixed wire guide is supported on the bottom plate of the moving unit. The movable wire guide is supported on the bottom plate of the casing. At least one of the movable wire guide and the fixed wire guide is supported rotatably.

An image forming apparatus includes a head unit, a conveyance unit, a lifting and lowering mechanism, a drive source and a transmission mechanism. The head unit is provided with an inkjet head having a discharge opening through which an ink is discharged. The conveyance unit is supported in an upwardly and downwardly movable manner in directions close to and apart from the head unit from a lower side. The lifting and lowering mechanism is configured to lift and lower the conveyance unit. The drive source is configured to drive the lifting and lowering mechanism. The transmission mechanism is configured to transmit driving force from the drive source to the lifting and lowering mechanism. The transmission mechanism includes a warm gear, a warm wheel meshed with the warm gear and a resistance applying member configured to apply resistance to rotation of the warm gear.

Provided is technology enabling detecting cockling in a print medium without printing a cockling detection pattern on the print medium. An image processing device has: a light source configured to illuminate a print medium; a sensor configured to scan the print medium; and a controller configured to control the light source and sensor. The controller determines if there is cockling in an evaluation area of the print medium based on change in the detection values of the sensor in the evaluation area.

An inkjet recording apparatus includes a printing and conveying unit, a recording head, a raising and lowering mechanism, and a controller. The printing and conveying unit conveys a sheet with the sheet loaded on a loading surface thereof. The recording head is disposed opposite to the loading surface and ejects ink onto the sheet conveyed by the printing and conveying unit. The raising and lowering mechanism includes a wire in contact with the printing and conveying unit. The raising and lowering mechanism winds the wire to raise and lower the printing and conveying unit relative the recording head in a cross direction interesting with the loading surface. The controller controls a winding operation by which the raising and lowering mechanism winds the wire according to a degree of inclination of the wire relative to the cross direction.

A recording apparatus includes discharge rollers configured to perform a discharge operation of discharging a recording medium on which an image has been recorded by a recording head to the outside of the recording apparatus, and a height-change member configured to change a height of the recording head in parallel with the discharging operation.
