Abstract: An orientation-adjustable infrared transceiver used in a notebook type computer. The infrared transceiver is installed in a container on a housing of the computer. A bottom of one end of the container is formed with a pivot socket and a lateral upper corner of the housing is formed with another pivot socket corresponding to the pivot socket of the container, whereby a pivot assembly is disposed in the pivot sockets to pivotally connect the container and the housing, permitting the container to be optionally rotated and located at one of multiple angles relative to the housing. Therefore, a user can adjust the orientation of the transceiving windows of the container according to the position of the object of the transceived infrared ray.
