<p>PURPOSE:To shorten a moving distance of a drive member moving a drive unit and to smooth the movement of the drive member in a device where plural recording media are selected. CONSTITUTION:Cartridges C stand by in waiting parts A1-A6. A supporting shaft 25 is guided by oblique guide parts 32a, 42b formed in linear on first, second drive members 30, 40, and the drive unit 20 is moved to a selective position in the waiting parts. Cam parts 56, 57 driving the drive members 30, 40 are formed on a rotating body 54. Circular arc parts shown by 56c and 57e are formed in the cam parts 56, 57, and when the drive member 30 or 40 is restricted by the circular arc parts, the drive unit 20 is positioned to the selective position to any waiting part. Since the part for positioning the drive unit to the oblique guide parts 32a, 42b is eliminated, the moving distances of the drive members 30, 40 are shortened, and further, the drive members are moved smoothly by cam drive.</p> |
