Abstract

The mechanism for opening and closing an operating cover of a printer having a discharge guide that remains in the same posture while moving in conjunction with opening and closing the operating cover prevents the gap between the discharge guide and the cover case of the operating cover from widening when the operating cover opens and closes. In a roll paper printer 1, the top end part 32a of the cover case 32 of an operating cover 3 is pivotably attached on the side of the discharge guide 5, which remains in the same posture while moving in conjunction with the cover 3 opening and closing. So that the cover case 32 does not separate from the cover frame 31 when the cover 3 opens and closes, a torsion spring 37 constantly urges the cover case 32 to open and close in unison with the cover frame 31 through an intervening connector arm 34. When the cover 3 opens and closes, a large gap is not formed between the top end part 32a of the cover case 32 and the discharge guide 5, and this gap does not increase in conjunction with the cover 3 opening and closing.

Description

technical field

[0001] The present invention relates to an opening and closing cover structure for opening and closing an opening of a paper storage section formed in a printer. More specifically, it relates to an improvement in the structure of an opening and closing cover that opens and closes members such as a discharge guide and the opening and closing cover together. Background technique

[0002] In roll paper printers that issue receipts and the like, roll paper in which long recording paper is wound into a roll structure is used as a recording medium. As a roll paper supply mechanism mounted on a roll paper printer, it is known that the roll paper is not supported in a rotatable state around the center of the roll by a support shaft such as a pull-out reel, but is only placed on the roll in a rollable state. The so-called "drop-in" structure of the bottom surface of the paper storage unit. In the feed-in type supply mechanism, it is not necessary to attach and detac...
