摘要:
A magnetic recording/reading apparatus comprises a head drum disposed on a deck to record or read information on/from a magnetic tape. An FPC fixing member is disposed on the deck to fix an FPC having a signal line to transmit a signal. The apparatus is configured to prevent noise generated between the head drum and the magnetic tape from transmitting to the outside and to a microphone. Thus, quality of recorded sound is improved.

Provided are a magnetic recording and/or reading apparatus and a method of manufacturing a power transmitting gear. The magnetic recording and/or reading apparatus includes a power transmitting gear. The power transmitting gear has one end coupled to a loading motor and the other end coupled to a plurality of link gears to transmit power from a loading motor to drive components during loading and unloading of a magnetic tape. The power transmitting gear includes a first gear engaged with a motor gear coupled to a shaft of the loading motor. The power transmitting gear also includes a second gear engaged with one of the plurality of link gears and a shaft member coupling the first and second gears. A space is formed inside the shaft member to prevent the shaft member from deforming during manufacture of the shaft member.

A lever fixing apparatus of a cassette housing has at least one lever for connecting a cassette holder to a chassis and at least one snap fixing unit for connecting the lever to at least one of the cassette holder and the chassis in a snap manner to hingedly fix the lever thereto. The lever fixing apparatus can fix the lever to the chassis without using additional coupling parts. Accordingly, the number of processes for assembling the cassette holder to the housing bracket can be reduced and the working time is saved, thereby the productivity being increased.

A head drum assembly and method of a magnetic recording/reproducing apparatus are disclosed. In the assembly, for application of a pre-load on the upper and the lower bearings, the upper and the lower bearings are installed in a loosely fitting manner on the shaft. An elastic member for applying a load on an inner ring of either of the upper and the lower bearings is provided so that simplification of the manufacturing process of the head drum assembly, cost reduction, and productivity improvement are achieved.

A deck mechanism for a magnetic recording/reproducing apparatus comprises a main deck provided with a head drum, a capstan motor, and a sub-deck installed on the main deck to be loaded/unloaded. The sub-deck is provided with a pair of reel discs, onto which tape reels of a tape cassette are seated; a pole base loading unit; a pinch roller unit for compressing the tape against a spindle of the capstan motor when the sub-deck is loaded; a brake unit; a main sliding member mounted on the main deck to be capable of reciprocatingly sliding, the main sliding member controlling the driving of the pinch roller unit; and a main cam gear mounted on the main deck. The main cam gear causes the sub-deck, the pole base loading unit, the brake unit, and the main sliding member to perform linked movements while the main cam gear is rotationally driven.
