Abstract: A continuously variable transmission comprising: an A input member that includes an input shaft and a toothed transmission section, a B output member that includes an output shaft and a toothed transmission section, a plurality of first toothed transmission sections, a moving device loaded with a rotary member plus a moving member and a baffle, and a box for axially supporting and housing each member and device; and the toothed transmission gears oppose each other, the toothed transmission gears and the first toothed transmission section each axially supported at the box are interlocked by gears, and the rotary member is rotatably loaded in contact with the moving device; a space is provided between the toothed transmission gears for inserting the rotary member and a lubricant oil therein to be in contact therewith, the moving device reciprocatingly moves in the space to interlock the toothed transmission gears and the first toothed transmission section by contact via the rotary member, thereby making it poss

Abstract: An indicator according to the present invention is used to indicate the presence or absence of a photo sensitive material in a film holder. The indicator comprises a pivotal indicator element and a actuating element. The pivotal indicator element has a pivot at its one end and is mounted on the surface of the film holder near its exposing window. The actuating element is adapted to be moved interlockingly with the pivot upon the insertion of the photo sensitive material and is provided facing a photo sensitive material receiving channel.

Abstract: In a film holder, a slot for receiving a marking member is made in a bottom flap of the film holder along the inner edge of the bottom flap. The slot is shaped such that when the marking member is inserted into the slot, a part of the marking member is opposed to a photo sensitive material and another part of the member is projected from the slot above the inner edge. Therefore, the marks or characters can be put on the photo sensitive material through the exposure to a photographing light.

Abstract: A film holder which is disclosed herein includes a inner frame defining a photo-sensitive plate insert slot between a partition plate, and outer frames each defining a dark slide insert groove between said inner frame. In this film holder, a plurality of stopper springs are formed on the peripheral sides of a body which is comprised of the partition plate and the inner frame. A plurality of hooks are formed on each the outer frames which are overlaid on the body to define the dark slide insert slot. These stopper springs and hooks are in the corresponding relationship, respectively, so that they are engaged with each other to lock the body and outer frames together in an overlaid relationship.

Abstract: Dark slides are insertable in a film holder. Each dark slide has engaging portions formed at its opposite ends of the upper edge of the dark slide. Sliding members are provided for sliding movement along the upper edge of the dark slide. Each sliding member has a locking portion at one end. A spring is provided for biasing the slide member to cause the sliding member to resiliently lock the dark slide.
