摘要:
The present invention provides a recording apparatus comprising a supply means for supplying a sheet in a predetermined direction, a convey means for conveying the sheet supplied by the supply means in a predetermined direction, a recording means for recording an image on the sheet conveyed by the convey means, in response to image information, a reversible drive means for driving the supply means and the convey means, and a drive transmitting means for transmitting a driving force from the drive means to the supply means or the convey means, and wherein the drive transmitting means comprises a plurality of planetary gears as means for rotating the supply means only in a sheet supplying direction regardless of a rotational direction of the convey means, and the planetary gears are revolved around gears having different speed reduction ratios from the drive means as sun gears, respectively. The present invention also provides a sheet supplying apparatus and a drive transmitting mechanism used with such a recording apparatus.

Each of a detection sample object and a non-detection sample object is illuminated with S-polarization light, for instance. S-polarization light and P-polarization light reflected from each sample object are detected by different photodetecting elements. Glossiness values and light quantities of the detection and non-detection sample objects are judged based on detection outputs of the photodetecting elements, and a glossiness difference and a light quantity difference are calculated. An evaluation function having at least one of the glossiness and the light quantity as a variable is determined by using the glossiness difference and the light quantity difference. Thresholds for object discrimination are calculated based on evaluation function values of the detection and non-detection sample objects.

To provide a reasonable and economical recording apparatus wherein an inevitable fluctuation of an intermediate transfer drum or the like does not adversely influence other elements. A recording apparatus wherein a toner image on a photosensitive drum (11) is primarily transferred to an intermediate transfer drum (21) and the toner image on the intermediate transfer drum (21) is secondarily transferred to a recording medium (100), characterized in that the apparatus comprises an intermediate transfer drum shifting device (40, 70) for shifting the intermediate transfer drum (21), during the primary transfer, into a first state wherein the intermediate transfer drum (21) is brought into press-contact with the photosensitive drum (11), and, during the secondary transfer, into a second state wherein the intermediate transfer drum (21) is brought into press-contact with the recording medium (100) but not brought into press-contact with the photosensitive drum (11).
摘要:
A frosting agent in which particulate silica suspends with high dispersibility without lowering the flow-out and formability of an aqueous polyurethane as a binder of frosting coating agent. Such a frosting agent for use in an aqueous polyurethane is obtained by adding 0.5-5.0 parts by weight of .gamma.-ureidopropyltriethoxysilane and 0.1 part by weight or more of water to 100 parts by weight of particulate silica and reacting said substances at a temperature of 15.degree.-100.degree. C. to modify the surface of said particulate silica. By this reaction, .gamma.-ureidopropylsilane liberated by hydrolysis of ethoxysilane groups reacts with acid hydroxy groups. Thus, the wettability and compatibility of the frosting agent with respect to aqueous polyurethane increases. This improves the dispersibility and the resistance to scuff of the coating.
摘要:
An apparatus for diluting and mixing specimen such as blood and a reagent, which is designed to prepare a mixed solution of a specimen and a reagent at a specific ratio by discharging the reagent in a passage for quantitative determination in a sampling valve by a specified amount of the reagent. The apparatus is designed so that specimen is discharged by reagent first at a low speed and thereafter at a usual speed by a reagent discharge device. The reagent discharge device may comprise a syringe, a pump having a thin film for forming air and liquid chambers, or the like. As constructed, the apparatus is not damaged due to fluid pressure.

An apparatus for feeding a printing sheet in a printer, including a gripper feeding belt for carrying grippers which grip a leading end of the printing sheet to feed it along a horizontal sheet feeding path; a plurality of toner printing units used for printing, in turn, colors of yellow (Y), magenta (M), cyan (C), and black (B), and arranged in series, at which a toner image is transferred to the printing sheet; and a plurality of sheet supporting belts arranged between the toner printing units to support the printing sheet in a horizontal state. The sheet supporting belt has at least one recess for receiving the gripper and is driven in synchronization with the grippers.

A hydraulically damped tensioner for a belt transmission system. A piston slidable with clearance in a cylinder form front and rear oil-filled chambers communicating through a passage in the piston with a check valve for restricting flow from the rear chamber to the front chamber. A piston rod is urged through the front chamber and against a roller by a spring in the rear chamber imparting tension on the belt. An opening, sealed by a removable plug, communicate with the front chamber to provide access for filling oil in both chambers.
摘要:
A vehicle air-conditioning discharge port structure wherein the airflow direction of air-conditioning drafts can be adjusted by changing the orientation of a plurality of fins provided to a discharge port. The fins include an outermost fin and an adjacent fin adjacent to the outer fins. The outer fin has a first regulating part for regulating the air-conditioning drafts flowing through an inter-fin flow passage between the outer fin and the adjacent fin, and a second regulating part for regulating the air-conditioning drafts flowing through a flow passage between the outer fin and a wall part.

A lid opening/closing mechanism switches a lid between a closed position closing an opening portion of a box-like base body, and an open position opening the opening portion. A distinct point is to include an arm allowing a tip side to turn to a front of the base body as a support point on a base end side pivotally supported at the base body by a first axis support portion, and connected to the lid turnably by a second axis support portion. The lid is turned in an opening direction or a closing direction in association with a turn of the arm.
