Abstract
A projector includes a light source device, a holder that accommodates the light source device, and a resilient member formed by bending a bar-shaped metal component is provided. The holder has a receiving portion configured to pivotally support the resilient member in such a manner that the resilient member can rotate toward the inside and outside of the holder, and an engaging portion configured to engage with the resilient member to regulate the rotation of the resilient member toward the outside of the holder. The resilient member engages with the engaging portion under the condition in which the light source device is accommodated in the holder to bias the light source device toward the holder.
Claims11
A projector comprising:
- a light source device;
- a holder that accommodates the light source device and includes a receiving portion and an engaging portion;
- and
- a resilient member comprising a bent bar-shaped metal component pivotally supported in the receiving portion and configured to engage with the engaging portion when the light source device is accommodated in the holder and bias the light source device toward the holder,
- wherein
- the resilient member is configured to rotate toward the inside and outside of the holder,
- the engaging portion is configured to engage with the resilient member to regulate the rotation of the resilient member toward the outside of the holder,
- the light source device shifts to the condition in which the light source device is allowed to be removed from the holder by releasing the biasing force against the light source device by rotating the resilient member toward the outside of the holder, and
- the engaging portion is disposed at a back of a reflector of the light source device and the receiving portion is disposed at a front of the reflector of the light source device, as viewed in an emitting direction of light from the light source device.
