Abstract: A method of driving a motor-driven shutter for a camera having a sector opening lever which is pivotal to open and close sectors, a sector opening cam movably supported and engageable with an engagement pin provided on the sector opening lever, an actuating member for pivoting the sector opening lever through engagement between the sector opening cam and the engagement pin, and a reversible motor for driving the actuating member. The motor is temporarily suspended when the actuating member is driven to a position where the sector opening cam comes into contact with the engagement pin, and the motor is restarted to cause the engagement pin to reach a predetermined position on the sector opening cam. Thus, it is possible to obtain a stable shutter opening operation and hence increase the degree of aperture accuracy.

Abstract: A double-decked apparatus has a base (4), and a movable deck (6) is rotatably connected, at one end, to one end of the base. Automobiles can be positioned on the base (4) and on the movable deck (6). The movable deck can rotate between a first position, where it is laid upon the base and positioned substantially parallel thereto, and a second position, where it is inclined upwardly. The apparatus is also provided with support rods (8, 9) which can hold the movable deck in the second position. Two automobiles can be mounted on this apparatus, one above the other. The apparatus can, therefore, help to achieve an efficient use of the space within a transport container.
