A pressing member illustrated in a developing unit (not shown) is pressed depending on the color developer in the unit.
SW 1 and/or SW 2 are turned on and off.
That is, when two switches are provided on the copying apparatus main body side, the developing unit can discriminate up to four different colors. Of course, if more information is required, additional switches may be added.
26 is a control circuit that turns on/off switches SW 1 and SW 2 .
Depending on the off state, for example, the drive power source 27 of the solenoid 28 (SL) that moves the red filter 8a onto the optical path is turned on. When the solenoid 28 is excited, the magnetic bar 29 slides on the guide member and is attracted. A wire 30 is attached to this magnetic bar 29.
One end is fixed, the other end is fixed to the shaft of the pulley 31, and the wire itself is suspended around the shaft. A wire 32 is suspended on one pulley, and the other end is fixed to the filter 8a. The filter 8a is urged by a spring 33 to the right in the figure (i.e., to a position away from the optical path), but the wire 30
is pulled out while rotating the shaft 31 counterclockwise,
As a result, the wire 32 is wound onto the pulley 31. In this way, the filter 8a moves onto the optical path against the biasing force of the spring 33.

By combining the pressing member with respect to SW 2 , it becomes possible to generate an information signal corresponding to a predetermined color developer. On the main body side, a predetermined filter is moved to the optical path in accordance with the information signal at the same time as the developing unit is installed in the same manner as described above.

The voltage applied to the corona discharger for forming a latent image may be switched for each unit and controlled to be set to each optimum value.

い。 Also, using a halogen lamp as the illumination light source,
When a CdS-binder type photoreceptor drum is used as a photoreceptor drum, the sensitivity of blue colors is somewhat poor, and the reproduction of color copies is not necessarily faithful. In this case, it is preferable to increase the exposure amount when passing through the blue filter compared to when using a red filter type green filter. For example, in the case of red and green, the same control mechanism as described above may be used to increase the halogen lighting voltage by about 20% for blue. Further, when blue is used as a reference, an ND filter with a light density may be used for red and green, overlapping each color filter at any time.
又、光路上の露光量調整スリツト或は絞りを所
定に調整制御するようにしても良い。 Further, an exposure adjustment slit or aperture on the optical path may be adjusted to a predetermined value.
