PROBLEM TO BE SOLVED: To provide a projector device which enables a user to easily and surely read the operation part of an operation means regardless of use environment when performing operation to the device while video light is projected under dark environment where there is no illumination. SOLUTION: The projector device is equipped with a video light output means 3 generating the desired video light, and the operation means 6 outputting a signal for performing the control of the device and performing the operation of the function of the device. Then, the operation parts are respectively prepared for the respective operation object items of the operation means 6, and are constituted so that an operation signal for displaying the content of the operation object item may be generated/outputted from the video light output means 3 by the flowing of a current through a resistance Ra when first pressing operation is performed, and the content of the operation object item may be carried out by the flowing of a current through parallel resistances comprising the resistance Ra and a resistance Rb when second operation is performed.
