PURPOSE:To reduce the number of parts and improve the assemble workability and operability by constituting a roll paper holder for an electronic device with a recorder so that the rotating angle of holder arms is made variable thereby the distance between a pair of the holder arms can be varied. CONSTITUTION:When holder arms 4a, 4'a are at an erect state I and a half- inclined position II, the distance between the cylindrical lugs 4d, 4'd of the arms 4a, 4'a is larger than the size of the roll paper width. When the roll paper is positioned to the lugs 4d, 4'd under these states I , II and further the arms 4a, 4'a are brought down to a position III, the arms 4a, 4'a are brought near to each other by means of a cam groove section 5'', the lugs 4d, 4'd hold the roll paper, the lugs of the arms 4a, 4'a not shown in the figure are coupled with the recesses of a guide groove 5''' not shown in the figure to fix the arms 4a, 4'a. According to this constitution, the number of parts is reduced and the assemble workability and operability can be improved. |
