Printer
A printer having a roll paper compartment 8 for housing a recording paper roll and a movable divider 83 for adjustably setting one side of the roll paper compartment 8 to adjustably accommodate different widths of roll paper and to facilitate placement of a remaining paper detector 90 in the roll paper compartment 8 for detecting how much paper remains on the paper roll. The divider facilitates installation of an after market remaining paper detector in the printer. The remaining paper detector can be positioned at a plurality of different angular positions around an axis of rotation substantially parallel to the widthwise direction of the printer. The roll paper compartment 8 of the printer 1 has a bottom 81 and a fixed side panel 82 for defining the other side of the roll paper compartment. The divider 83 is removably connected to the bottom 81 , and can be selectively fixed to any one of a multiple number of positions along the width of the printer parallel to the longitudinal axis thereof.
1. A printer having a roll paper compartment for housing a recording paper roll, the roll paper compartment comprising:
a bottom panel;
a fixed side panel defining one side of the roll paper compartment in alignment with the width of the printer parallel to its longitudinal axis; and
a movable divider defining another side of the roll paper compartment in substantial alignment with the width of the printer with said movable divider located opposite said fixed side panel and having one or more connecting member(s) for detachably connecting said movable divider to said bottom panel such that said movable divider can assume a plurality of different positions laterally displaced from one another in alignment with said fixed side panel to adjustably accommodate different widths of roll paper and to facilitate placement of a remaining paper detector in the roll paper compartment for detecting if the paper remaining on the paper roll is less than or equal to a predetermined amount;
said movable divider being removably assembled to the bottom panel and having a detector mounting part for removably installing said remaining paper detector;
wherein the divider is removably connected to one of a multiple number of positions in said roll paper compartment space apart along the bottom panel for adjusting the location of the divider widthwise to the printer;
wherein the divider comprises a plurality of protruding pins or a plurality of recessed holes; and
wherein the bottom panel has a set of complementary holes for inserting the pins, or a set of complementary pins for insertion into the recessed holes, at a selected one of the multiple positions widthwise to the printer.
