Abstract: A camera has a motion compensation device which is stable in operation. A motion detection unit determine motions of the camera and a motion compensation unit drives a motion compensation optical system to remove blur of an image due to the motion of the camera. A communication unit transmits operating instructions based upon the amount of motion from the motion detection unit to the motion compensation unit and a monitoring unit determines whether an anomaly exists in the operating instructions. A locking unit locks the motion compensation optical system in a centering position if the anomaly exists. According to another embodiment, the motion compensation optical system is driven to a center position prior to the performance of the motion compensation and inhibits movement by the motion compensation optical system if a defect occurs during the centering operation.

Abstract: An electrical circuit has a power source line from a battery. The power source line is divided into a primary side and a secondary side by a device, such as, for example, a diode. A high current load circuit is connected to the primary side and a lower current device, such as, for example, a display-related circuit and a capacitor are connected to the secondary side. The display-related circuit continues to receive adequate power when the battery voltage drops due to operation of the high current load circuit. In addition, a voltage detector is connected to the secondary side, where the voltage fluctuates less than on the primary side. The voltage detector controls operation of the high current load circuit. As a result, the high current load circuit can be efficiently driven.

The printed substrate includes multiple layer conductive patterns, through-holes which pass through the conductive patterns and the printed substrate, and reinforcement patterns formed around the perimeters of the through-holes in the multiple layers of the printed substrate. The sizes and/or shapes of the reinforcement patterns in each layer differ such that stress acting on the border of the reinforcement pattern is distributed.

Abstract: An inductive load drive circuit for driving an inductive load, such as a motor, and for preventing charging of a power source by the back electromotive force of an inductive load. The inductive load drive circuit uses a battery as the power source for supplying power to the load. A first switching mechanism can serially connect and disconnect the inductive load and the battery. The first switching mechanism is controlled so that it disconnects the inductive load from the battery when the inductive load is in a condition in which the inductive load is able to generate back electromotive force or when the inductive load will be shifted to such a condition. Moreover, a bypass circuit can be used to consume the energy of the back electromotive force of the inductive load. A second switching mechanism is serially connected to the bypass circuit, with the serial combination of the second switching mechanism and the bypass circuit being in parallel with the power source.

The main camera body is equipped with a flat portion on one portion of the outer wall that forms a film chamber comprising either a cartridge chamber or a spool chamber. A mounting board has a section that faces and is substantially parallel to the flat portion and an extension section that does not face the flat portion. A horizontal or vertical electrical connecter is attached to the extension section of the mounting board on the surface generally facing the outer wall of the film chamber and an electrical board comprising an FPC board or the like is connected to the electrical connecter. To enhance the features of the camera, a first electrical component is loaded on the surface of the mounting board opposite to the electrical connector loaded surface.
