Roll paper holding mechanism and printer

Pressing plates press side faces of a roll paper loaded into a roll paper holder unit of the drop-in type, thereby preventing overrun of the roll paper caused by an inertia force from occurring. Each of the pressing plates is urged by two coil springs which are placed respectively on inner and outer circumference sides of the roll paper. The coil spring on the outer circumference side has a higher elasticity than the coil spring on the inner circumference side. According to the configuration, the pressing force of the pressing plates due to the elasticity of the coil springs is gradually reduced in accordance with reduction of a diameter of the roll paper.

Drive power supply and fail determination method

A drive power supply for generating inverter drive voltages has a switching control circuit that switches a switching element on a primary side of a transformer to generate drive voltages on the secondary side in connection with the switching of switching elements of the inverter. A feedback circuit generates a feedback voltage corresponding to the drive voltages and supplies the feedback voltage to the switching control circuit to control the drive voltages. An abnormality detecting portion changes the feedback voltage when the voltage of a predetermined terminal fluctuates. Thus when an IG short involving the predetermined terminal occurs, the drive voltages are changed by the switching control circuit sensing the change in the feedback voltage. Since any change in the drive voltages is detected to reliably determine an abnormality, an IG short is detected as an abnormality even though the abnormality has been generated in the drive power supply independent of any prior change in the actual drive voltages.
