Patent ID: 7059558

Claim:
A recording material containing device for a recording material roll constituted by winding of recording material, comprising: a containing chamber for containing said recording material roll; a supply roller, secured to said containing chamber in a rotatable manner, for rotating said recording material roll by contacting an outermost turn of said recording material roll, to advance said recording material to an outside of said containing chamber upon separation from said recording material roll; and a pressing mechanism, including a pressing roller disposed away from said supply roller in a winding or unwinding direction of said recording material roll, said pressing roller being caused in said pressing mechanism to press said outermost turn of said recording material roll; an actuating mechanism, associated with said pressing mechanism, for setting said pressing roller in a releasing position before loading of said recording material roll, to form a space in said containing chamber greater than a maximum diameter of said recording material roll, so as to facilitate said loading, and for setting said pressing roller in a pressing position after said loading, to press said outermost turn of said recording material roll; a pair of bearing mechanisms, each of which has a U-shaped gap for supporting a shaft protruding from ends of said recording material roll in a removable and rotatable manner, said shaft being included in a roll holder fitted on said recording material roll; a pair of supply roller support levers for supporting said supply roller in a rotatable manner therebetween, each of said supply roller support levers including first and second ends, said first end constituting a center about which said supply roller support levers are rotatable, said second end supporting said supply roller; a pair of pressing roller support arms, secured to respectively said supply roller support levers in a rotatable manner, each of said support arms including third and fourth ends, said third end supporting said pressing roller in a rotatable manner between said support arms; an auxiliary pressing roller, secured to said fourth end in a rotatable manner between said support arms, positioned downstream from said supply roller with reference to said roll inserting direction, for contacting said outermost turn of said recording material roll; and a spring for biasing said supply roller support levers rotationally in a first direction, to set said pressing roller in said pressing position, and to set said supply roller in contact with said outermost turn of said recording material roll.
