摘要： A transfer device used in an electrophotographic recorder capable of effectively prevent paper jamming and transfer missing in a transfer process, which comprises a guide member of an insulating material disposed at a downstream side wall end of a casing and an insulating member of current interruption disposed at an upstream side wall end of the casing, in which the guide member, even when subjected to heat, stably keeps its rigidly mounted state and prevents the falling of the paper into an opening of the casing, and the insulating member of current interruption minimizes the flow of a transfer current from a charging wire toward a small-diameter rubber roller to prevent the transfer missing.

摘要： A transfer unit has a plastic end block at each end. The end block includes a bearing for supporting an auxiliary roller, and an arm having at its end portion a pivot received by a lower casing. The bearing and the arm are formed integrally with the end block. A leaf spring located under the transfer unit supports it along with the roller in movable around the pivot. When an upper casing is shut down, a photoreceptor drum supported in the upper casing pushes down the transfer unit against the elastic force of the leaf spring. Since the positions of the transfer unit and the roller are determined with respect to the photoreceptor drum, good duplicativity can be obtained. In this state, roller means serves to secure a predetermined space between the photoreceptor drum and the auxialiary roller.

摘要： A developing apparatus including a hopper storing toner and carrier and a roller disposed in an opening of the hopper. A carrier stopper is provided on a front wall of the hopper proximate the opening having an arced surface concentrically opposing an upper portion of the roller. Thus, a blend layer volume is formed in a first space between the carrier stopper and the roller for storing a blended layer of carrier and toner such that the carrier stopper prevents carrier from scattering outside the blend layer volume and the conjunctional effect of rotating the roller and of the magnetic force of the rotary magnets in the roller blends the carrier and toner stored in the blended layer. A sub-hopper, proximate the blend layer volume, is also formed by a second space between the carrier stopper and a lateral bottom wall of the hopper for storing toner to be provided to the blended layer.

The bearing and the arm are formed integrally with the end block. A leaf spring located under the transfer unit supports it along with the roller in movable relationship around the pivot. When an upper casing is shut down, a photoreceptor drum supported in the upper casing pushes down the transfer unit against the elastic force of the leaf spring. Since the positions of the transfer unit and the roller are determined with respect to the photoreceptor drum, good duplicativity can be obtained. In this state, a cylindrical spacer serves to secure a predetermined space between the photoreceptor drum and the auxiliary roller.

摘要： PURPOSE:To enable to always stably feed a heat-fusible ink film without complicating a feeding mechanism, by feeding a recording sheet and the heat-fusible ink film in opposite directions. CONSTITUTION:The first feeding rollers 11 are provided for a recording sheet 1 on the downstream side of a thermal head 3, the sheet 1 is fed by the rollers 11 in the direction of an arrow A, while the second feeding rollers 12 feed the heat- fusible ink film 2 at a velocity of lower than the feeding velocity of the sheet 1 in the opposite direction of an arrow C while exerting a tension on the film 2. Accordingly, frictional forces fH, fP exerted on the ink film 2 are opposite to the feeding direction C of the ink film 2. As a result, even when the large-small relationship of the forces fH, fP is changed, the ink film is fed at a constantly fixed velocity without sagging.

摘要： PURPOSE:To secure a stable shifting speed of an original in a reading part of an image sensor, and also to cause no paper jam by bringing pinch roller into contact with a platen roller, also driving at least one of those rollers, and carrying an original led in between them by those rollers. CONSTITUTION:An original 23 fed in between original guides 28, 29 by an automatic feed paper roller 21 is further fed in between a platen roller 25 and a pinch roller 27. The fed original 23 is fed into between an image sensor 24 and the platen roller 25 by a driving force of the platen roller 25, in a state that it is pinched and pressed by the platen roller 25 and the pinch roller 27, welded softly by pressure betwen them, and carried in the direction of a tray. Accordingly, even if a load following the carrying of the original generated by a friction resistance of the automtic feed paper roller 21 and a selecting piece 26 and the original 23 is generated between the platen roller 25 and the pinch roller 27, an influence of the load is not exerted between a picture information reading part 24a and the platen roller 25.
