Title:
HEAD RELEASE MECHANISM OF PRINTER
Document Type and Number:
WIPO Patent Application WO/1996/016815
Kind Code:
A1
Abstract:
A tape cartridge (4) can be detachably fitted to a fitting portion (5) of a printer (20) and this fitting portion (5) is covered with a cover (22). When the cover (22) is closed, its protuberance (51) rotates a turning member (54), and an operation end (54b) of the turning member (54) moves a moving member (55). When the operation end (54b) runs over the upper end of a surface A of the guide surface (55a) of the moving member, the cover is completely closed and the turning member (54) is thereafter guided by a surface B and is held in the engagement state with the surface B. A head supporting member (59) rotates in the interlocking arrangement with the moving member (55), and a head (6) at the distal end of this member (59) is fixed at a printing position. The turning member (54) is separated from the protuberance (51) of the cover when the printing position is so formed. Therefore, a load does not act from the side of the head (6) to the side of the cover (22). When a cover open button (24) is pushed down, the turning member (54) leaves the surface B of the moving member, forming thereby a release state of the head. According to the present invention, a head release mechanism of a printer can be operated in the interlocking arrangement with the open/close operation of the cover, and no load acts from the head side on the cover.
