Printing apparatus with cutter mechanism

摘要

A movable BF guide is provided in a movable-blade receiving area into which a movable blade slides along a fixed blade while being pressed against the fixed blade in a process of cutting recording paper. The movable-blade receiving area is blocked by the BF guide when the cutting process is not performed, thus preventing the entry of the end portion of the downstream connected recording paper into the movable-blade receiving area.

主权项

1. A printing apparatus with a cutter mechanism, comprising:
a conveying path along which a roll-type recording paper is conveyed; conveying means that conveys the recording paper along the conveying path; printing means that prints on the recording paper that is conveyed along the conveying path; cutting means including a fixed blade and a movable blade that are disposed so as to be opposed to each other across the conveying path; a movable paper-conveyance guiding member provided in a movable-blade receiving area into which the movable blade slides in a process of cutting the recording paper, the paper-conveyance guiding member including a projecting portion that projects toward the conveying path beyond a cutting edge of the fixed blade when the cutting process is not performed, the paper-conveyance guiding member comprising two guide members forming a V-shape through rotation when the cutting process is performed so that the paper-conveyance guiding member is moved away from the conveying path when the cutting process is performed; and a controller configured to control the conveying means to feed the recording paper forward toward a downstream side in a conveying direction by a first predetermined amount and then feed the recording paper backward toward an upstream side in the conveying direction by a second predetermined amount during the time from when the recording paper is cut to when a printing operation is started.
