Provided are a projection type display device, a control method of a projection type display device, and a control program of a projection type display device, capable of fixing a position of a combiner to a desired position to enhance usability without imposing a burden on an operator of a working machine. An HUD 100 includes a rotating part 15A that supports the combiner 12 to be rotatable between an in-use position and a withdrawal position, a locking mechanism 15B that prohibits rotation of the combiner 12, and a projection display section 50 that spatially modulates light emitted from a light source on the basis of image information, and projects image light obtained through the spatial modulation onto a projection surface 12A of the combiner 12 to display an image based on the image light, a locking mechanism controller 63 that controls the locking mechanism 15B on the basis of a traveling state of a construction machine 1 or an operating state of a bucket 4A.
