Abstract

PURPOSE:To constitute the titled device as a small-sized and compact device and to improve portability by arranging an image pickup lens system to the intermediate part of a U-shaped substrate surrounding a substrate on which a solid-state image pickup element is fitted to form an image on the image pickup element. CONSTITUTION:The solenoid-state image pickup element 2 is fitted to a circuit substrate 3c through a socket arranged on the center and respective substrates are connected through connectors. When the image pickup lens 1 is arranged on the intermediate part of the U-shaped circuit substrate the image pickup device is constituted so that the circuit substrates 3a, 3b are arranged on the upper and lower positions respectively, the right and left sides of the lens 1 are opened and no trouble is not generated to execute an operation such as focusing of the lens, zooming and diaphragm adjustment. When the image pickup device is constituted so that the substrates 3a, 3b are arranged on the right and left positions, the upper and lower sides are opened. Since switches required for the operation of the device are fitted to the substrate 3b, the operation can be executed through an aperture or the like formed on a case body 4. Thus, unnecessary parts can be omitted.
