发明名称 SLR camera with auxiliary light emitter
摘要 A pop-up flash unit 20 for an SLR camera includes an integral auxiliary light emitting device 26 for projecting a predetermined pattern along the camera lens axis to provide sufficient auto-focusing contrast. A triangular prism 60 forms a window in a front wall 16a of the flash unit chamber 16 confronting the condenser lens 25 of the auxiliary light emitting device such that the predetermined pattern projected by the downwardly angled emitting device, when the flash unit is retracted, is bent upwardly to still fall along the camera lens axis.
