Integrated disk driving module including a stepping motor integrally formed with a base unit

An integrated disk driving module, the module comprising:

• a base unit including a stepping motor fixture bent from an upper plate toward an accommodation space and the stepping motor fixture is integrally formed with the upper plate;
• a stepping motor rotatably fixed to the stepping motor fixture and including a lead screw and a pivot member arranged on a distal end of the lead screw to be fixed at the stepping motor fixture, the pivot member including a clip unit coupled to the stepping motor fixture by press-fitting;
• an optical pickup module fed by the stepping motor;
• first and second guide shafts coupled to the upper plate of the base unit to guide the optical pickup module, the base unit further including a pair of guide shaft fixtures bent from the upper plate to a direction of the accommodation space for respectively fixing a first distal end of the first guide shaft and a second distal end of the first guide shaft, and a pair of second guide shaft fixtures bent from the upper plate to the direction of the accommodation space for respectively fixing a third distal end of the second guide shaft and a fourth distal end of the second guide shaft;
• and
• a first pressure member configured to press the clip unit and the first distal end of the first guide shaft near the clip unit,
• wherein the stepping motor fixture includes:
• a first fixture rotatably supporting one lateral end of the lead screw;
• and
• a second fixture rotatably supporting the other lateral end facing the one lateral end,
• wherein the first fixture is formed with a through hole through which the one lateral end of the lead screw passes,
• wherein the second fixture is formed with an insertion hole through which a periphery of the other lateral end of the lead screw is inserted,
• wherein the through hole of the first fixture has an oblong shape,
• wherein the clip unit is protruded from a front face of the pivot member, and
• wherein the first pressure member includes:
• a body fixed at the upper plate,
• a first pressure unit extended and bent from the body to press to the clip unit, and
• a second pressure unit extended and bent from the body to press to the first distal end of the guide shaft near the clip unit.
