The invention relates to the field of design of head up displays, in particular to a reflection screen taking-up and paying-off mechanism of a head up display. The reflection screen taking-up and paying-off mechanism of the head up display comprises a main body framework, a sliding seat and a reflection screen, wherein a first guide rail and a guide rail rack are arranged on the lateral surface of the main body framework, a second guide rail and a lead screw are arranged at the bottom of the main body framework, a lead screw is also provided, and one end of the lead screw is connected with a motor; the lateral surface of the sliding seat is provided with a boss used for being inserted into the first guide rail and a driving gear used for being meshed with the guide rail rack; a through hole sleeved with the second guide rail and a spiral tooth used for being meshed with the lead screw are arranged at the bottom of the sliding seat; the length of the first guide rail and the guide rail rack is smaller than that of the second guide rail and the lead screw; the reflection screen is installed at the top end of the sliding seat. By means of the technical scheme, a novel reflection screen taking-up and paying-off mode is provided, and the reflection screen is taken up and paid off along the rail and is more advanced and technical.
