Description

[Brief explanation of the drawing]

Fig. 1 is a vertical sectional view of the developing unit set at a predetermined position within the copying machine main body, with the copying machine main body omitted and only the outline of the unit carrier shown. The figure is a schematic perspective view showing the unit carrier removed from the copying machine main body and the developing unit separated from the unit carrier.
FIG. 3 is a front view of the developing unit and unit carrier set at predetermined positions in the copying machine main body. In order to make the figure easier to understand, the copying machine main body and toner replenishing device are omitted, and the developing Figure 4 is a simplified view of the unit; Figure 4 is a front view similar to Figure 3 with the front plate of the unit carrier removed; Figure 5 is a plan view of the guide member fixed to the main body of the copying machine. Figures 6a and 6b, which show the guide groove and guide pin provided on the unit carrier side with chain lines, show the state in which the developing unit and unit carrier are set, and the state in which they are pulled out. FIGS. 7a, b, and c, which are schematic explanatory views of the state seen from the left side of FIG. 1 to explain the operation, are similar to FIG. 6 when the developing unit and unit carrier are pulled out from the set state. Figure 1 is a schematic explanatory view from above, showing how the developing unit rotates and the photoconductor drum FIG. 10 is an explanatory diagram showing the situation when it is separated from the copying machine, with some elements omitted and shown in a simplified manner. FIG. FIG. 1 is a cross-sectional view showing a state in which the device is supported on a floor surface or the like, with some elements omitted and simplified as in FIG. 9;
Figure 1 is a side view showing the same state as Figure 10, with some parts omitted and simplified, and Figures 12a and b show the stand device in its folded state and in its used state. Fig. 13 is a plan view showing the drive system of the developing unit, with some elements omitted, and Fig. 14 shows the idle gear engaged with the gear of the developing unit. FIG. 15 is an explanatory diagram illustrating the state in which the idle gear is disengaged from the gear of the developing unit. DESCRIPTION OF SYMBOLS 1...Developing unit, 200...Unit carrier, 213...Handle, 218...Stand device.

Claims (1)

[Claims for Utility Model Registration] (1) A developing unit that visualizes an electrostatic latent image formed on a latent image carrier, a unit carrier that supports the unit, and a unit that can be folded into the carrier. and a stand device attached thereto, the unit carrier is supported by the main body of the image forming apparatus so as to be detachable from the main body of the image forming apparatus while supporting the developing unit, and the unit carrier detached from the main body of the copying machine is attached to the stand device. 1. A developing device in an image forming apparatus, characterized in that the developing device is supported by a support surface. (2) The utility model registration according to claim 1, characterized in that the unit carrier is provided with a handle, and the handle cooperates with the stand device to support the unit carrier on the support surface. developing device.
