A follower roller is brought into press contact with a driving roller by a load having a predetermined value, thereby being rotated in accordance with a rotation of the driving roller to transport the medium clamped therebetween in a first direction. The follower roller includes a shaft portion and a roller body provided so as to surround the shaft portion. The follower roller is configured such that a value of a ratio f/F is not greater than 0.03. Here, F is a force transporting the medium in the first direction which is generated by the load, and f is a resistance force generated in a second direction opposite to the first direction by a friction loss of the shaft portion of the follower roller which is generated by the load.

A sucking device having a fixed material transportation surface including plural sucking holes, a decompression chamber connecting to the plural sucking holes, and a sucking device sucking air in the decompression chamber is set at discharging side of the fixed material. The fixed material is fed on the fixed material transportation surface of the sucking device by the delivering device, and is stuck on the fixed material transportation surface through the sucking holes by the sucking device. The fixed material is fixed by a fixing head at the state being stuck and is transported gradually to a downstream side from an upstream side by the delivering device on the fixed material transportation surface. After that, when fixing is finished, the fixed material separates from surface of the fixed material transportation surface and rises slightly by blowing air from the sucking holes by a blowing device so as to move to discharging direction, that is, the downstream side by an auxiliary transporting device. Thus, since the fixed material is discharge smoothly, the prior discharging serrated roller is unnecessary so that spur mark run over caused by the discharging serrated roller does not remain on the fixed material at discharging.

A projection optical system which has a short projection distance and a compact structure, and allows oblique projection. The projection optical system projects luminous flux from an image forming element for forming an original image onto a projection surface which is oblique to a central principal ray which is a principal ray of luminous flux traveling from the center of the original image to the center of a finally formed image. The system includes a plurality of reflecting surfaces each having a curvature. In addition, the projection optical system satisfies a predetermined expression (1).

A liquid ejection head is operable to eject a liquid droplet toward a medium at a liquid ejection point A first roller transports the medium toward the liquid ejection point. A second roller ejects the medium transported from the liquid ejection point to the outside of the apparatus. At least one detection roller is directly brought into contact with the medium and is rotated in accordance with the transportation of the medium, the at least one detection roller being disposed in the vicinity of at least one of the first roller and the second roller. A detector detects a rotation amount of the detection roller. A controller controls the transportation of the medium in accordance with the rotation amount.

A display panel, such as a liquid crystal panel, fixed onto a holder plate is aligned with other optical members, and while the alignment is maintained, the holder plate is fixed onto a panel-fixing frame with solder. At least one of the holder plate and the panel-fixing frame at the fixing region is provided with an opening or a cut, whereby the scattering of the solder around the fixing region is prevented and an improved fixing strength is attained.
