ABSTRACT:
A door lock assembly which includes an electronic card reader is provided whereby when the clutch assembly is in the activated position, rotational movement of the outside handle is transmitted by way of a spindle through the mortise and through the clutch assembly to a clutch disk disposed between the mortise and clutch assemblies and the inside housing. The clutch disk is disposed inside the door. Rotational movement of the clutch disk is then imparted back towards the door through a drive disk and hub drive to the mortise latch hub which is disposed in the mortise housing disposed inside the door structure. As a result, the clutch disk and clutch assembly can be disposed between the inside housing and the inside door surface and the electronic components of the card reader and clutch assembly can be conveniently housed in the inside housing assembly. An additional spacer hub is disposed between the outside housing and the mortise latch hub which makes it difficult to tamper with the mortise latch hub from the outside of the door.
