    摘要： Provided is an image projecting apparatus, including: a polarization separator having a polarization separation surface which transmits or reflects illumination light and reflection light reflected from a reflective image display unit according to polarization directions of the illumination light and the reflection light; and a polarization direction rotating member, disposed between the polarization separator and the reflective image display unit, which rotates a polarization direction of light passing twice through the polarization direction rotating member by 90° about an optical axis of the polarization separator. The polarization separator and the polarization direction rotating member are disposed such that an axis bisecting an angle between a principal ray of the illumination light passing from the polarization separation surface to the reflective image display unit and a principal ray of the reflection light reflected from the reflective image display unit is approximately consistent with the optical axis of the polarization separator.

    摘要： A tow feeding apparatus which requires no continuous observation, shortens the reset time when tow is wound around pinch rolls for feeding into a case, and operates safely, includes guide rolls for leading a tow to a winding roll or pinch rolls, a winding roll apparatus provided between the guide rolls and pinch rolls at a normal position for winding up a tow around a winding roll when wrapping trouble occurs at the pinch rolls. A pinch roll apparatus for feeding the tow from the guide rolls through the winding roll apparatus into a case, and a transport device for transporting the winding roll apparatus from the normal position to a reset position behind the pinch roll apparatus when wrapping trouble occurs. A cutter shears the tow along the tow route before the pinch roll apparatus. An exchanger for substituting the pinch roll apparatus with another set of pinch rolls, and a detector for detecting wrapping of a tow around the pinch rolls are further included. A controller receives a signal from said detector to actuate the cutter and the driving motor for driving the winding roll, stops the pinch roll apparatus, drives the exchanger, actuates the transport device for moving the winding roll apparatus from the normal position to the reset position, starts the pinch roll apparatus at the same time as the winding roll apparatus is stopped, and returns the winding roll to the normal position.
