Apparatus for elevating squeegee roller and development roller for liquid printer

An apparatus for elevating a squeegee roller and a development roller for a liquid printer, comprising:

• a pair of first supporting blocks which rotatably support both ends of the development roller that transfers a developer liquid to a transfer surface of a photoreceptor belt;
• a pair of second supporting blocks which rotatably support both ends of the squeegee roller that compresses the transfer surface of the photoreceptor belt and removes liquid carrier contained in transferred developer liquid;
• a pair of cases, wherein one of the first supporting blocks and one of the second supporting blocks are elevatably accommodated parallel to each other in one of the cases, and wherein an other of the first supporting blocks and an other of the second supporting blocks are elevatably accommodated parallel to each other in an other of the cases;
• a first elevating means for elevating the cases relative to the photoreceptor belt;
• a driver unit for driving the first elevating means;
• and
• a second elevating means for elevating the first and second supporting blocks in sequence with the elevation of the cases.
