ABSTRACT:
A laser beam printer with variable paper feeding capacity includes a body having a cassette mounting portion with a paper feeding device and a cassette mounting rail, at the bottom thereof. This permits the use of a minimum capacity paper cassette and a large capacity paper cassette independently formed with paper holding portions of different capacities. The cassettes may each have a channel along which the cassette mounting rail slides, at both sides thereof, and a plate for supporting paper which receives elasticity from a spring. The printer may make use of a height compensation mechanism installed at the bottom of the body. This mechanism permits the height of the cassette mounting portion of the body to be higher, such as when the large capacity paper cassette is selectively used. Therefore, the printer is efficiently used by selectively employing the minimum capacity paper cassette and large capacity paper cassette, in accordance with usage environment of users.
