Abstract of the Disclosure Disclosed is an improved pinch roller moving device for a simultaneous image and sound recording cinecamera. The device includes a first lever on which the pinch roller is supported rotatably and transversely movably and a second lever rotatable to rotate the first lever to press the pinch roller against a capstan. A cam is provided to rotate the second lever and a third lever is provided to hold the first lever against rotation. The third lever is rotatable upon rotation of a second cam to release the first lever for rotation. A fourth lever is provided for maintaining the second lever in its rotated position. The device further includes means for transmitting rotation of a cap- stan driving motor to the cams. This motor is operable upon depression of a release button on the cinecamera. - 1 -
