Abstract:
1. A recording medium supply device having a cassette capable of stacking recording media thereon attachably and detachably mounted on a mounting position of a body of the device and feeding the recording media stacked on the cassette, the device comprising: a feeding roller which feeds the uppermost recording media stacked on the cassette; a plate for supporting the recording media stacked on the cassette; a biasing unit for biasing the recording media upward via the plate; a regulating unit which regulates a height of the uppermost recording medium stacked on the cassette against the biasing unit when the cassette is mounted on the recording medium supply device; and a movement regulating member being movable between projecting position and accommodating position, wherein the movement regulating member regulates that the recording medium stacked on the cassette move relative to the cassette in a direction in which the cassette is moved to the mounting position when the movement regulating member is located at the projection position, wherein a height of the uppermost recording medium regulated by the regulating unit is higher than a front wall of the cassette, and the height of the movement regulating member located at the projecting position is higher than the height of the uppermost recording medium regulated by the regulating unit, wherein the movement regulating member moves to the projecting position in the process of movement of the cassette to the mounting position, and wherein the movement regulating member is located at the accommodating position where the movement regulating member does not regulate movement of the recording media stacked on the cassette when the feeding roller rotates.
