Abstract

A label printer for printing predetermined data on and issuing labels includes a tubular roll holder (101) secured at one end to a vertical wall (11a), a slide member (102) slidably accommodated within the hollow of the roll holder (101), and a roll retaining lever (103) connected to the slide member 102for pivotal movement between folded and erected positions. The roll retaining lever (103) has one end portion (103a) protruding outwardly from the hollow of the roll support shaft through a slot (101a) defied in the roll holder (101) in communication with the hollow thereof, when the roll retaining lever (103) is pivoted to the erected position, to thereby retain a roll (R) of the ribbon-shaped label sheet (Rp) in position on the roll holder (101) to avoid any possible lateral displacement thereof, but the roll retaining lever (103) when in the folded position lies substantially parallel to a longitudinal axis of the roll holder (101) to allow the label roll (R) to be mounted onto the roll holder (101). By this design, not only can the label roll (R) be retained in position on the roll holder (101) within a label supply unit (100) to avoid any possible lateral displacement thereof along the roll holder (101), but also the position at which the roll retaining lever (101) is to be erected can be adjusted. Also, the label roll (R) can be quickly and easily mounted on the roll holder (101).
