Abstract: In a recording medium transporting mechanism, a flange member is attached on either side of a roll paper and the flange member has a diameter smaller than a maximum outer diameter of a roll paper. Support rollers support a corresponding one of the flange members in a rotatable manner. The support rollers are moveable along the axis of rotation of the roll paper. The sum of an outer diameter of corresponding one of the flange members and the support rollers is greater than a maximum outer diameter of the roll paper. A rewinding roller of at least a length equivalent to a distance between both sets of support rollers when the sets of support rollers are farthest apart is engaged with a support roller within the set of support rollers and can rotate the flange member in a rewinding direction over a desired amount of continuous time.

Abstract: An electronic digital pressure switch for detecting gas pressures features improved safety. The digital pressure switch that detects gas pressures and generates outputs has a housing provided with pinholes that allow a gas to pass therethrough. With this arrangement, even if a gas should leak into the housing, the leakage gas is let out through the pinholes. Thus, when the pressure of a flammable gas is detected, it is possible to eliminate the danger of an explosion caused by the flammable gas accumulating in the housing.
