摘要： A projection apparatus including a projection module, a control unit, a housing, a wireless-receiving unit and a control panel is provided. The control unit is electrically connected to the projection module for controlling the projection module. The housing is suitable for accommodating the projection module and the control unit and has a concavity exposed outside. The wireless-receiving unit is disposed inside the housing and is electrically connected to the control unit. The control panel is detachably installed in the concavity. When the control panel is installed in the concavity, the control panel is electrically connected to the control unit such that the control panel is suitable for providing an electric signal to the control unit for controlling the projection module. When the control panel is detached from the concavity, the control panel is suitable for providing a wireless signal to the wireless-receiving unit for controlling the projection module.
