<p>PROBLEM TO BE SOLVED: To prevent an area with formed images of a recording medium from deviating from a proper area by freely moving a side regulating plate by a prescribed distance in a width direction in a state that the side regulating plate is fixed by a fixing means. SOLUTION: In a side regulating plate 22 and a fixing means 90, a side regulating side cam and a fixing means side cam for separating positions of the plate 22 and the means 90 each other at the time of rotation are formed. Because the front side regulating plate 22 is energized in a direction that the front side regulating side cam and the fixing means side cam are separated by a compressive coil spring in a fixing state, the front side regulating plate 22 is capable of freely moving in an arrow B direction according to stress acting on the front side regulating plate 22. Therefore, the front side regulating plate 22 and a rear side regulating plate 24 are capable of moving by a prescribed distance in a width direction (the arrow B direction) in a state that the plates 22 and 24 are fixed by the fixing means 90. Even if the recording medium is strongly pressed on the side regulating plates 22, 24, a slight gap is formed because the recording medium pushes back the side regulating plates 22, 24 in the width direction.</p> |
