Patent attributes
A PC card slot device for an ExpressCard affords a smooth insertion of the ExpressCard into a slot for the PC card slot device, without the height of the slot being increased. A lower chassis ceiling wall defines the lower face side of a card storage space, and also includes a slot side edge that is formed of a rear-side inclined line portion and a slot-side inclined line portion. The rear-side inclined line portion and the slot-side inclined line portion are respectively inclined at angles α1 and α2, relative to a reference cross section. To insert the ExpressCard into the slot of the card storage space, the right corner of the right upper level lower face portion of the card is inserted into the card storage space and the front end of the right stepped portion of the card is guided along the inclined line portions.
