摘要： A sheet feeder provided in an image forming device and includes a sheet feed roller, a pair of rollers provided at both ends of the sheet feed roller and rotatable independent of the sheet feed roller, and a separation pad provided in confronting relation to the sheet feed roller and the pair of rollers. The sheet feed roller has a circumferential surface portion and a cut-out surface portion. When the cut-out surface portion is opposite a sheet and the separating pad, outer peripheral surface portions of the pair of rollers contact the sheet at approximately the same level position that the circumferential surface portion of the feed roller contacts the sheet. This maintains the separating pad in approximately the same position.

摘要： In a cassette for accomodating therein a continuous photo-sensitive recording medium a light-shield member is arranged in a feed passage communicating an accomodating chamber for the recording medium and a drawing opening through which the recording medium is drawn out of the cassette. The light-shield member is movable between its operative and inoperative positions. In it operative position, the light-shield member closes the feed passage to prevent the penetration of the ambient light. In its inoperative position, the light-shield member does not obstract drawing out of the recording medium.

摘要： In a cassette for accommodating therein a photo-sensitive recording medium, a pair of cassette halves formed of synthetic resin are united together to form a cassette body having defined therein an accommodating chamber for the recording medium. A drawing opening is formed in an outer surface of the cassette body. The recording medium is drawn out of the accommodating chamber through the drawing opening. An optically inert feed passage is defined by cooperation of a wall section of one of the pair of cassette halves with a wall section of the other cassette half when the one and other cassette halves are united together. The feed passage has one end thereof communicating with the accommodating chamber and the other end communicating with the drawing opening such that the recording medium passes through the feed passage when the recording medium is drawn out of the accommodating chamber through the drawing opening.

摘要： In a color picture recording apparatus, a picture image of an original document is formed on a photosensitive and pressure-sensitive recording medium which may be either a self-coloring type or a transfer type made up of a microcapsule sheet and a developer sheet. According to one aspect of the present invention, in the recording apparatus of the type in which the transfer type recording medium is used, the copy sheets are discharged face-up so as to facilitate an operator's confirmation of the copied picture image. According to another aspect of the invention, the cut developer sheets are stacked in a sheet cassette so that the surface on which the developer material is coated is face-down so that a feeding roller for feeding out the developer sheet does not come into contact therewith. According to still another aspect of the invention, in an apparatus of the type in which a mask member is used for forming a latent image on the recording medium, the mask member and the recording medium are held in intimate contact with each other when exposure is taking place.

摘要： An image forming device having a sheet conveying path extending from a feeder unit to an image forming unit. A convey roller positioned downstream of the sheet supply roller is rotated at a peripheral speed V3. Additional convey roller positioned downstream of the first convey roller is rotated at a peripheral speed V2 lower than V3. A register roller positioned downstream of the second convey roller is rotated at a peripheral speed V1 lower than V2. A transfer roller of the image forming unit is rotated at a peripheral speed V0 lower than V1. Each convey roller, the register roller, the sheet supply roller is connected to each clutch. Sheet sensors are provided between neighboring rollers for detecting a leading edge of the sheet. Upon detection of the leading edge, the roller positioned immediately upstream of the one of the sensors is shifted to its non-driving state.

摘要： A developing unit including a developing chamber provided with a rotatable developing sleeve and a magnet roller capable of rotating inside the developing sleeve, and a first agitator for agitating a developer, and an agitation chamber provided with a second agitator for supplying a magnetic toner to the developing chamber. A restriction member, formed of a magnetic material, is suspended between the developing chamber and the agitation chamber. A free end of the restriction member extends toward the first agitator and a toner supply slit is formed below the lower, or free, end of the restriction member so that the magnetic toner supplied by the second agitator in the agitation chamber is conducted to the first agitator without direct contact with the developing sleeve. As a result, the magnetic toner can be supplied and agitated positively and stably.
