Abstract
The present invention provides an optical scanning control device and a retina scanning projection device provided with a structure for suppressing heat transfer to a laser module, and a heat dissipation structure for dissipating the heat of the laser module. The optical scanning control device () is configured to emit, as image light, a laser light in accordance with an image signal. The optical scanning control device includes: a housing () made of metal; a laser module () configured to emit laser light, which abuts the top of the base () of the housing, and is arranged on one side inside the housing; a power supply unit () arranged inside the housing on a side opposite that of the laser module; and an electronic circuit board () having heat source members (IC chips) configured to cause the laser module to emit image light, the electronic circuit board being arranged on a side opposite the base-side of the laser module. The heat source members are arranged on a surface on a side of the electronic circuit board facing away from the laser module, and are at positions which avoid a position directly above the laser module.
