    • A paper termination detecting apparatus for detecting an amount of a paper roll that is below a predetermined amount of paper, having: a detecting lever (63) including a detecting piece (64) being allowed to put into a space of a core part of the paper roll, and a protruding piece (65) spaced a predetermined distance apart from the detecting piece, the protruding piece being allowed to come in contact with a side of the paper roll; and a detecting switch (67) for converting a motion of the detecting lever into an electrical signal when the detecting piece puts into the space of the core part of the paper roll.

    • The present invention provides a novel structure of a tape cartridge (10) accommodating a printing tape (T) and an ink ribbon (R) used for printing, which prevents the printing tape from being stuck in a cartridge case or the ink ribbon (R) from being slackened. The tape cartridge (10) of the invention has a mechanism for preventing an end of the tape from being reversely moved back into the cartridge case. A typical structure of the mechanism includes an anti-inversion system which prevents a tape core having a tape wound thereon from rotating in a reverse direction, that is, a direction opposite to a normal rotating direction for printing. The anti-inversion effects are removed when the tape cartridge (10) is set in a printing device such as a tape writer to ensure smooth feeding of the tape for printing. When the tape is forcibly pressed back into the cartridge case, a movable platen clamps the tape between the platen and a fixed wall to prevent reverse movement of the tape. The tape cartridge of the invention also includes an anti-slack mechanism for preventing slack of the ink ribbon (R) through engagement of a ribbon winding core with an anti-rotational engagement piece. Engagement of this anti-slack mechanism is also released when the tape cartridge is set in the printing device.
    • 本发明提供一种容纳打印带和用于打印的墨带的带盒的新颖结构,其防止打印带被卡在盒壳体中或墨带松弛。 本发明的带盒具有用于防止带的端部反向移回到盒壳体中的机构。 该机构的典型结构包括防反转系统,其防止具有缠绕在其上的带的带芯沿相反方向旋转,即与用于打印的正常旋转方向相反的方向。 当将带盒设置在诸如磁带写入器的打印装置中时,防反转效果被去除以确保用于打印的带的平滑馈送。 当磁带被强制地压回到盒壳体中时,可移动的压板将带夹在压板和固定壁之间以防止带的反向移动。 本发明的带盒还包括用于通过将带状卷绕芯与抗旋转接合件接合来防止色带松弛的防松松机构。 当将盒式磁带安装在打印装置中时,也会释放该防松机构的接合。
