摘要: A thin cartridge to which a connector of the present invention is applied has an insertion space therein which is open through an opening formed on an end face of a frame thereof. A printed circuit board having terminals patterned on an edge surface portion thereof is provided on one of surfaces defining the insertion space. The connector includes an engagement wall to be inserted into the frame as a single component for engagement with the frame of the cartridge. The engagement wall has first and second opposite faces exposed to the outside. Arrangement of contact members retained in retention grooves formed in the first face can be viewed from the side opposed to the first face.
