PROBLEM TO BE SOLVED: To provide a roller bearing support device capable of enhancing the silent sound effect, while improving an image quality by reducing the transmission of vibration from a driving motor. SOLUTION: This roller bearing support device 1 supports a roller 3 having one rotary shaft 3a by three bearing parts, and has a body part 4 having a first bearing part 5 for supporting one end side of the rotary shaft 3a of the roller 3 and a second bearing part 6 for supporting an intermediate part near the other end side of the rotary shaft 3a, and a motor installing part 11 for installing the driving motor 10 for rotatingly driving a third bearing part 9 for supporting the other end side of the rotary shaft 3a and the rotary shaft 3a, and has a support member 7 constituted separately from the body part 4. The support member 7 can move in the radial direction of the roller 3 to the body part 4, and is held so as not to separate from the body part 4 in the shaft direction of the roller 3.
