Abstract

Small, lightweight, low-profile electronic still cameras have a camera body with a slot load unit suitable for PC cards and can be manufactured at low cost. The electronic still camera has a camera body having a slot load unit that can be loaded into a slot for accommodating a PC card as a card-type recording medium for an external device. The camera body has an optical system unit having a photographing lens and an imaging element. The camera body also includes a signal processing unit for converting an output signal from an image pickup device into an image signal, and a memory for storing the image signal. The slot load unit has a PC card side connector connected to a connector in a PC card slot of an external device, and an interface connected to both the memory and the PC card side connector to communicate between the PC card interface and the memory.
