ABSTRACT:
A lightweight and compact hand-held ocular fundus imaging apparatus is provided wherein alignment can be easily performed while ensuring a working length. An examiner takes hold of a grip by hand and secures a face pad against part of the face of a patient. The examiner performs alignment by tilting a reflecting mirror, and when alignment is complete, an image of the fundus of the patient's eye is taken. An optical system except for the reflecting mirror is disposed on the inside of a main body portion that includes the grip and the face pad, and the reflecting mirror is disposed on the outside of the main body portion. A lever for tilting the reflecting mirror is disposed on the grip. With this type of configuration, the alignment operation can be performed easily and reliably by moving the reflecting mirror while maintaining the apparatus main body in a stable state.
