Claims

[Scope of utility model registration request]

The supporting shaft of the recording paper roll is placed on the guide slope, and the circumferential side of the recording paper roll is brought into contact with the brake plate to hold the recording paper roll, and when the recording paper is fed out from the recording paper roll, the above-mentioned In the recording paper roll holding structure in which tension is applied to the recording paper by the frictional force between the brake plate and the recording paper roll, the contact surface of the brake plate with the recording paper roll has different coefficients of friction. The contact surface is divided into at least two upper and lower parts by forming a layer of material, and the coefficient of friction between the brake plate and the recording paper roll is reduced at the upper part of the contact surface, and the friction coefficient between the brake plate and the recording paper roll is reduced at the lower part of the contact surface. A recording paper roll holding structure characterized by a large coefficient of frictional force between the recording paper roll and the recording paper roll.
