摘要： PROBLEM TO BE SOLVED: To provide a fixing structure of a printed circuit board which allows a low profile electronic device, with no increase in the number of parts and with strong electrical connection between a pattern and a fixing member.
SOLUTION: The fixing structure of a printed circuit board electrically connects a pattern of the printed circuit board to the fixing member, thereby fixing both of them. The fixing member (1) includes a cut and raised part (1a) which is cut and raised and then bent back, with a first hole (1a2) provided, and a burr part (1b) which is countered to a first through hole (1a2) and has a threaded hole (1c). A printed circuit board (2) includes a slit (2c) formed to adjoin a pattern (2b) or a second hole (32c). By tightening a screw (3) which is inserted into the first hole (1a2) and the slit (2c) or the second hole (32c) for engagement with the threaded hole (1c), the cut and raised part (1a) presses the pattern (2b).

The member to be press-fitted has a press-fitting portion (ANB) and an opposed portion (KTB) opposed at an interval to the peripheral surface (8d1) of the annular member which are respectively formed on the inner peripheral surface (8d1) of a hole for press-fitting sequentially from the side of an opening. The opposed portion includes a first opposed portion (KT1) having a top portion (TB) with the minimum diameter and leading from the press-fitting portion to the top portion, and a second opposed portion (KT2) on a side opposite to the press-fitting portion with respect to the top portion. A press-fitting and fixing process includes an adhesive applying process applying a thermosetting adhesive (17) to the first opposed portion, a press-fitting process press-fitting the annular member into the hole so that the peripheral surface (10d) of the annular member is opposed to the second opposed portion, and a heating process curing the adhesive.

摘要： PROBLEM TO BE SOLVED: To prevent off-tracking of a head on a disk by suppressing deflection of a motor base.
SOLUTION: A brushless motor 10 with a core is provided for rotatably mounting a disk D on which information signal is recorded or reproduced with a head 34 movable in radial direction of the disk. In a stator core 13, teeth parts 13b are protruded radially from an annular core part 13a by a multiple of the number of coil driving phases. When a motor driving coil 14 is wound on the teeth parts 13b of the stator core, coil clearance holes 11b1 in which the coils 14 wound on the teeth parts are inserted are formed on a motor base 11, decreasing the quantity by the number of coil driving phases multiplied with N (N is natural number) to the number of teeth parts. Meanwhile, the number of turns of motor driving coil on the teeth parts corresponding to the portions where no coil clearance hole is formed is set to be zero or less than the number of turns of motor driving coil on the teeth parts corresponding to the portions where the coil clearance holes are formed.
