PURPOSE:To enable easy and speedy replacement of a rolled form paper, by providing brackets on the same substrate as that for a printer on the front side of a printing mechanism part of the printer, and detachably fitting a roll of a printing paper to the brackets. CONSTITUTION:A roll of a printing paper 12 is disposed on the side of, and spaced from, a printing mechanism part provided on one side surface of a printer 10, and both end parts of a support shaft 26 passed through the rolled form paper 12 are disengageably fitted in shaft holes 21 in brackets 22, 24 fixed on a substrate 14 used also for the printer 10. A guide member 32 comprising a slanted top plate 34 and side plates 38 is provided, the top plate 34 of which has one end part surrounding the rolled form paper 12 and the other end part directed toward a paper-supplying port of the printing mechanism part. The guide member 32 is provided with notches 40 in end parts on the rolled form paper side of the side plates 36, 38 thereof, and the notches 40 are rotatably engaged with the support shaft 26. Positioning collars 28, 30 are attached respectively to both ends of the shaft 26, and the side plates 36, 38 of the guide member 32 are set to press the rolled form paper 12 from both sides, thereby applying an elastic brake to the rotation of the rolled form paper 12. |
