Title: Image pickup device having image rotation mechanism
Inventor: TOGANO KANEYOSHI
IPC: H04N5/253
Filed: 1993-01-27
Abstract: PURPOSE:To obtain a device having a compact image rotation mechanism with low driving force, which can rotate an image, by separating an image pickup optical block into an optical block including a lens system and an image pickup block including an image pickup element, constituting them in different bodies and holding the image pickup block in the optical block so that it can be rotated. CONSTITUTION:The image pickup block 4 provided with the image pickup element on a front-side is fitted to the optical block 3 including the lens system of the image pickup optical block 2 so that it can be rotated. An image rotation operation is executed by the rotation of the image pickup block 4. Namely, the optical block 3 does not move during a rotation operation and therefore space for the rotation of a zoom motor 5 and an AF motor 6 and space for removing/-turning a lens driving system signal line 7 become unnecessary. Thus, a main body becomes compact. Since the image pickup block 4 is held by the optical block 3 so that it can be rotated, the image on a screen rotates with the rotation of the incorporated image pickup element when the optical block is rotated during the image rotation operation.

Title: Damper of worm gear decelerating mechanism
Inventor: SEKINE HIDEJI
IPC: B60J1/17
Filed: 1988-02-12
Abstract: PURPOSE:To reduce the production cost by connecting a worm wheel to an output shaft with a resilient board and transmitting the revolution of the worm wheel to the output shaft via the resilient board. CONSTITUTION:When an impact is generated due to sudden variation in load to turn an output shaft 4 in the reverse direction, the impact to a worm wheel 3 is attenuated by a resilient board 5 connecting the output shaft 4 to the worm wheel 3. Thus both the teeth 2a of the worm 2 and the teeth 3a of a worm wheel 3 engaged therewith may be prevented from being damaged by the impact. In the application of cyclic starting and interruption, the impact may be absorbed by the resilient board 5 and similarly, both the teeth 2a of the worm 2 and the teeth 3a of the worm wheel 3 may be protected from the impact. Because of the factors that such sufficient impactabsorbing ability is ensured, a thin gear housing 10 is realized and the need for vulcanizing adhesion is eliminated, the production cost may be reduced.

IPC: G03B5/00
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To improve handleability and to accurately detect blur. SOLUTION: A viewing angle change decision part 410 decides based on an angular velocity signal outputted from an amplification part 20 whether or not a viewing angle is changed. An elapsed time measuring part 420 measures an elapsed time based on the decision on the finish of the change of the viewing angle by the decision part 410. The measuring part 420 measures the elapsed time till a specified time when a drift amount by an HPF(high-pass filter) 25 becomes sufficiently small. A processing signal selection part 430 elects the angular velocity signal passed through the HPF 25 when the specified time elpases after finishing the change of the viewing angle. The selection part 430 selects the angular velocity signal which does not pass through the HPF 25 within the specified time after finishing the change of the viewing angle.  As a result, the optimum angular velocity signal in accordance with photographing circumstances is selected and the blur is accurately corrected.
