    1482251 Magnetic brush developer XEROX CORP 29 Oct 1975 [20 Nov 1974] 44652/75 Heading G2H The housing of a magnetic brush developer comprises two relatively-movable sections that can be un-latched in such a way that flow of developer is prevented. The fixed housing section includes development rolls 51-54 and transport rolls 57- 58. The sump section 56 is movable laterally i.e. parallel to the axes of the rolls. It is latched by a lever 96 attached to the shaft of a magnetic flow gate 101 when a thumb screw 97 engages a notch 98. In the latched position developer is free to flow. The lever is biased by a spring to the unlatched position, shown in full lines, when the gate prevents developer flow.

    (54) DEVICE FOR DISPLAY IN ELECTROPHOTOGRAPHIC DEVICE
    I
    The invention relates to devices for display in an electrographic apparatus.
    A device for manifestation in an electrographic apparatus is known, comprising a bunker with an extender, a means of transporting the developer and its mixing enclosed in a common housing 1.
    The known device is inconvenient to maintain.
    In order to improve the servicing of the device, its body is made of two detachable sections, one of which is fixed, the transfer means is located in the fixed section, and the bunker with the developer and its mixing means in the movable section, which has a lock for connection to the fixed section and a magnetic gate located at the outlet of the bunker and kinematically connected with the lock.
    The lock and the magnetic shutter are mounted on a common shaft, one end of which is mounted on the pin, on the movable section, and contains a torsion spring, and on the other end there is a lever with a magnetic shutter.
    FIG. 1 shows the device, a general view; in fig. - Castle.
    The device comprises a housing 1 made of two detachable sections 2 and 3. Section 2 is fixed on the housing 1 stationary, 5 and section 3 is movable.
    In the movable section 3, the bunker 4 with the developer and the tool 5 for mixing the developer are placed. In the fixed section 2, the mounted transfer means of the developer from the hopper 4 through the outlet 6. 10 The transfer vehicle of the developer contains rollers 7 and 8. The developer is a mixture of finely divided particles of resinous toner and larger particles of a ferromagnetic carrier.
    With rollers 7 and 8, the developer is transmitted upwards between the photoconductor 9 and the successive transfer rollers 10-13. Between the rollers 7, 8, 10-13, the developer is held by means of permanent magnets 14-19, which are located inside individual non-magnetic cylindrical sleeves 20-25.

    The latter are rotated in the direction of the arrows, and the developer held onto them by means of the stationary fields created by the magnets 14-19 moves from roller to roller. The floor formed by the magnets is of such a form that the developer on the rollers 10-13 tends to be assembled with feet in the form of bristles in the passage between the rollers 10-13 and the photoconductor 9. As a result, the developer is thrown onto the photoconductor 9 and lubricates it. In order for these formed magnetic brushes to have a generally identical profile across the width of the zone 26, a control flap is used, which determines the profile of the developer held by the magnetic means on the nepiBOM transmitting roller 7. After passing between photo probe 9 and the last roller 13, the developer is deposited on the slider 27. A part of the developer passes into the automatic means 28 of monitoring the development along the chute 29, but most of it remains on the slider 27 until it reaches the means 5 of the This will restore the developer to recirculate and then return it to the hopper 4. A toner dispenser 30 is installed above the moving tool 5 to restore the developer. Thus, the additional toner, which is supplied from time to time for the BMS & RH concentration of the toner in the Veitel, is carefully transferred with a recycled propellant. The toner dispenser 30 has a bone 31. The movable section 3 is connected to the fixed section 2 by means of a lock 32, to interrupt the flow of the developer. The lock 32 is located on the shaft 33, which is mounted on a pin for rotation in the movable section 3 of the housing I and is displaced by means of torsion springs 34. The free end of the lock 32 is provided with a screw jacket 35, for which in the fixed section 2 of the housing 1 there is an opening 36 during engagement. Magnetic shutter 37 is located at the outlet 6 of the bunker, which, like the lock, is mounted on shaft 33. Magnetic shutter 37 has a permanent magnet 38, which attracts the ferromagnetic carrier from the developer and runs across the entire width of the bunker 4. Magnetic strength 38, length shutter 37 and its angular orientation relative to lock 32 are selected so that the developer can freely flow from bunker 4 when the iiiHT-wings 35 are in hole 36. When the lock is unlocked, the bias caused by spring 34 causes the magnet 38 to abut against bunke 4, approximately at the level of the outlet opening 6. Thus, the flow of the developer from the hopper 4 is interrupted obrazuyuscheys jumper from the developer. The rollers for producer 10-13 and the transfer rollers 7 and 8 can be cleared from the developer by unlocking the lock 32, then after a short operation of the display system 39, the developer who was on the rollers can be recirculated back to the bunker 4. Formula for invention manifestations in an electrophotographic apparatus, containing a bunker with witnesses, a means of transporting the reader and his moving, enclosed in a common housing, characterized in that, in order to improve the maintenance of the device, the housing is made of two connectors x sections, one of which is fixed and contains the transfer means of the developer, and the bunker with the developer and its mixing means are located in the movable section that has a lock for connection to the fixed section and a magnetic gate located at the outlet of the hopper and kinematically connected with the lock, the lock and the Magnetic Shutter are mounted on a common shaft, one end of which is mounted on the pin, on the movable section, and contains a torsion spring, and a lever with a magnetic shutter is mounted on the other end.
