Abstract

PURPOSE: To stabilize paper-feeding by enabling the strength of a spring for pushing a bottom plate to be easily changed in accordance with the quality of paper accumulated in a cassette.
CONSTITUTION: A cassette 1, is rotatably engaged with the base part 2a of a bottom plate 2 at the middle step 1a on its upper face. An upper side spring-holding plate 3 and a lower side spring-holding plate 4 are arranged between the upper face of the cassette 1 and the bottom plate 2, and rotatably pivotted at their bases. Between their tops, a spring 6 is provided to be easily slided forward and backward. When a lever 8 is turned from 0 to 9 of the dial shown in an indicating area 10, spring-holding 3 and 4 are slided forward. This construction permits to obtain a paper-feeding pressure adequate to the paper quality and stabilize the paper-feeding even if the paper quality is changed, since the spring-hodling plate 3 can be slided forward or backward to change the strength of the spring 6 easily for pushing the bottom plate 2.
