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

1. 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.

2. The integrated disk driving module of claim 1 , wherein the base unit includes a lateral surface plate bent from an edge of an opening-formed upper plate to form the accommodation space.

3. The integrated disk driving module of claim 2 , wherein each of the stepping motor fixtures is arranged on a straight line, each in parallel with the other.

4. The integrated disk driving module of claim 1 , wherein the stepping motor fixture is formed in a pair from the upper plate, each facing the other.

5. The integrated disk driving module of claim 1 , wherein the insertion hole is an insertion groove.

6. The integrated disk driving module of claim 1 , further comprising a spindle motor mounted at the mounting plate coupled to the upper plate via a coupling screw.

7. The integrated disk driving module of claim 1 , wherein one of first guide shaft fixtures fixed to the first distal end is formed with a through hole through which the first distal end passes, and the remaining one first guide shaft fixture fixed to the second distal end is formed with an insert groove through which the second distal end is inserted.

8. The integrated disk driving module of claim 1 , wherein one of second guide shaft fixtures fixed to the third distal end is formed with a through hole through which the third distal end passes, and the remaining one second guide shaft fixture fixed to the fourth distal end is formed with an insert groove through which the fourth distal end is inserted.

9. The integrated disk driving module of claim 1 , further comprising:

a second pressure member fixed at the upper plate for applying pressure to the second distal end,

a third pressure member fixed at the upper plate for applying pressure to the third distal end, and

a fourth pressure member fixed at the upper plate for applying pressure to the fourth distal end.

10. The integrated disk driving module of claim 9 , wherein each of the first through fourth pressure members includes a leaf spring.

11. The integrated disk driving module of claim 1 , further comprising:

a height adjustment screw coupled to the upper plate of the base unit to adjust heights of the first and second distal ends of the first guide shaft, and coupled to the upper plate of the base unit to adjust heights of the third and fourth distal ends of the second guide shaft.
