PURPOSE:To prevent scattering of a roll film and deterioration printing accuracy at the time of high speed rotation by setting bearings for supporting the roll film displaceably in the axial direction, pressing both bearings with springs so as to approach them each other, and adjusting one side bearing with an adjusting screw. CONSTITUTION:Bearing holders 11 are fixed to the side walls 10 of a cartridge case 1, and the bearings 12, 13 are set slidably in the axial direction of a film holder 9. A compressible coil spring 14 is set between the bearing 2 and the left wall 10L to press the bearing 12 in the right direction. The bearing 13 is provided with a controllable spring guide pin 15, and another compressible coil spring 17 is set between the right end flange 16 of the pin 15 and the bearing 13, and the adjusting screw 18 is screwedly engaged with the right side wall 10R of the case 1 opposite to the flange 16 to press the bearing 13 through the spring 17 in the left direction, thus permitting the roll film to be wound on the proper position of the recording cylinder and to be prevented from its scattering and deterioration of printing accuracy at the time of high speed rotation. |
