ROLL PAPER HOLDER AND ASSEMBLY METHOD THEREOF

To provide a roll paper holder that can improve both assemblability and usability of a cover plate.SOLUTION: A roll paper holder includes: a holder body 11; a core member 12 that supports a cylindrical core of roll paper at both ends; and a cover plate 13 that is rotatably assembled in the holder body 11. The cover plate 13 is provided with a pair of spindle pins 13B which is rotatably inserted into a pair of groove parts 11F of the holder body 11. The holder body 11 is provided with a narrow opening part 11R which narrows an opening end of each groove part 11F. Each spindle pin 13B is made to have a non-circular shape having a large diameter part wider than an opening width of the narrow opening part 11R and a small diameter part B2 narrower than that. The cover plate 13, before the assembly of the core member 12, can be rotated in a prescribed direction D in which the small diameter part B2 can be inserted into the groove part 11F through the narrow opening part 11R for the holder body 11. However, the rotation in the prescribed direction D is regulated by contact with the core member 12 which is assembled in the holder body 11.SELECTED DRAWING: Figure 6 【課題】カバー板の組み付け性と使用性の双方の向上を図ることが可能なロールペーパホルダを提供すること。【解決手段】ロールペーパホルダは、ホルダ本体１１と、ロールペーパの筒芯を両端支持する芯部材１２と、ホルダ本体１１に回転可能に組み付けられるカバー板１３と、を有する。カバー板１３が、ホルダ本体１１の一対の溝部１１Ｆに回転可能に差し込まれる一対の支軸ピン１３Ｂを有する。ホルダ本体１１が、各溝部１１Ｆの開口端を狭める狭口部１１Ｒを有する。各支軸ピン１３Ｂが、狭口部１１Ｒの口幅よりも広い大径部と狭い小径部Ｂ２とを有する非円形形状とされる。カバー板１３は、芯部材１２の組み付け前は、ホルダ本体１１に対して小径部Ｂ２を狭口部１１Ｒに通して溝部１１Ｆへと差し込める所定の向きＤに回転させることができるが、ホルダ本体１１に組み付けられる芯部材１２との当接により所定の向きＤへの回転が規制される。【選択図】図６
