A sheet feed tray to stack a sheet to be conveyed to an image forming apparatus includes a platen on which a first portion of the sheet is placed; a pair of first support portions to support a second portion of the sheet folded back upward at a trailing end of the first portion; and a pair of second support portions to support a third portion of the sheet folded back upward at a trailing end of the second portion. In the sheet feed tray, the first support portions and the second support portions are reciprocally movable toward each other, and a distance between the second support portions is wider than a distance between the first support portions.

A tandem type direct printing apparatus 2 comprising a plurality of printing stations 16a, 16b, 16c and 16d for depositing printing particles 38 on a print medium 8 to form a layer of printing particles. The plurality of printing stations 16a, 16b, 16c and 16d are positioned in a moving direction of the print medium 8. The printing station positioned downstream with respect to the moving direction of the print medium forms a layer of printing particles on the layer of printing particles formed by the printing station positioned upstream. At least any one of the printing stations 16a, 16b, 16c and 16d is different in intention of the electric field from another by changing the voltage applied to the backing electrode 44 or the distance between the backing electrode 44 and the printing head 50 in accordance with a charge quantity of printing particles or the number of the layer of printing particles in the one of the printing stations.

A still camera for recording an object image by making use of an electronic signal such as a still video camera is so constructed that a recording medium is positioned nearly in parallel with an optical axis of a taking lens system and also in the lateral direction to the taking lens system. Therefore, the camera body thereof can be formed in a flat shape, and additionally a red-eye phenomenon can be prevented from occurring by arranging a light emitting portion of an electronic flash device and the taking lens system sufficiently apart from each other.

This invention is directed to a camera provided with an automatic focus adjusting apparatus in which, in addition to the function of carrying out an AE lock based on an in-focus detection, an AE lock can be carried out either before or after an AF operation is completed or when an AF operation is impossible. In other words, irrespective of the condition of an automatic focus adjusting means, an AE lock can be accomplished at any desired moment. Therefore, the degree of freedom in a photography operation is expanded.

A gas hydrate production apparatus capable of reacting a raw gas with a raw water to thereby form a slurry gas hydrate and capable of removing water from the slurry gas hydrate by means of a gravitational dewatering unit. The gravitational dewatering unit is one including a cylindrical first tower body; a cylindrical dewatering part disposed on top of the first tower body; a water receiving part disposed outside the dewatering part; and a cylindrical second tower body disposed on top of the dewatering part, wherein the cross-sectional area of the second tower body is continuously or intermittently increased upward from the bottom.

In producing gas hydrate pellets by compression-molding a gas hydrate powder, heat generated in a compressing part is removed with a simple method so as to reduce the degree of gas hydrate decomposition, and a gas hydrate aggregate blocking the compressing part is promptly and easily removed. A gas-hydrate-pellet production apparatus A is characterized by including: a roll-cooling mechanism which causes cooling water to flow through outer peripheral portions and/or insides of rolls 6a and 6b, thereby cooling the rolls 6a and 6b, and also cools the cooling water 43 discharged after the flow and supplies the cooled cooling water 43 to the outer peripheral portion and/or the inner portion of each of the rolls 6a and 6b; and/or heating means provided in a part of a hopper chamber 5 from which the gas hydrate powder n is fed to the rolls 6a and 6b.

A recording apparatus of the present invention includes a bearing member for bearing a recording medium having toner and carrier and a backing electrode opposing to the bearing member for electrically attracting the toner on the bearing member. The toner and carrier are charged to opposite polarities. A substrate having a plurality of apertures is provided between the bearing member and the backing electrode. This allows the toner to propel from the bearing member toward the backing electrode. Further, both the toner and carrier have respective volume mean diameters smaller than a diameter of the apertures, and the volume mean diameter of the toner is larger than that of the toner. With the arrangement, the toner will propel through each aperture to form a corresponding image portion, i.e., dot, thereby forming a high quality image without any dot-defect.
