Label printer

Abstract

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