<p>PURPOSE:To locate an imaging unit using a simple structure. CONSTITUTION:The arrangement according to the present invention comprises a heat roller 50 and pressure roller 51 which can take the attitude in pressure contacting mutually and the attitude disengaged from the pressure contacting, a pressure contact mechanism composed of a spring 63, etc., to put the two rollers 50, 51 in pressure contact, a pressure contact releasing lever 65 which can take the first position to admit pressure contact of the pressure contact mechanism and the second position to release the pressure contact, and a spring 66 to energize the lever 65 toward the second position. When in first position, the lever 65 presses the imaging unit concerned upward with the energization force of the spring 66.</p> |
