Abstract

PURPOSE: To obtain a high-quality recorded/reproduced picture, by providing the switching mechanism to switch the reading intervals of the secondary scanning direction read out by the reading element and thus giving a rough reading to increase (or decrease) the quantity of reading equivalent to a secondary scanning.
CONSTITUTION: The switch lever 13 is provided and then turned toward the arrow B. Thus the transmission roller 12 is pressed to the pulley part 9a of the running roller 9 as well as to the pulley part 10c of the timing disk 10 each. If the diameter of the part 10c is set to 1/2 diameter of the part 9a, the speed of rotation of the disk 10 becomes double speed of the roller 9. Accordingly, the reading interval of the secondary scanning direction is lowered down to 1/2 compared with when the lever 13 is turned toward A. In other words, a finer reading is secured to increase the image resolution.
