Abstract: A pinch roller assembly for a magnetic recording and reproducing apparatus has a pinch roller configured to selectively contact a capstan axis mounted on a deck base. A pinch arm is provided for rotatably supporting the pinch roller on one end thereof. The pinch arm is pivotally mounted on the deck base for movement between first position and second positions. When in first position, the pinch roller is adjacent to the capstan axis, and when in the second position the pinch roller is spaced away from the capstan axis. A pinch axis is mounted on the other end of the pinch arm. The pinch axis is a pivot point of the pinch arm. A pinch spring is disposed on the pinch axis to elastically support the pinch arm when being pivoted to the first position toward the capstan axis. A separation preventing protrusion is integrally formed with the pinch axis to prevent deviation of the pinch spring.

Abstract: A stator assembly of a motor for a head drum is provided to generate a driving force disposed opposite to a motor rotor. The stator motor includes a double sided flexible printed circuit (FPC). A signal line is formed in a pattern is formed on both sides of the flexible printed circuit (FPC) for inputting an electrical signal. A plurality of wound driving coils are connected to a first side of the flexible printed circuit (FPC) to electrically connect with the signal line. A yoke is connected to a second side of the flexible printed circuit (FPC).

Abstract: A method for assembling a head-drum assembly for a magnetic recording/reproducing apparatus is provided. The head-drum assembly is assembled by inserting a shaft to a fixed drum first, setting up a motor stator in the fixed drum, and putting a rotary drum assembly and drum cover assembly into the shaft sequentially. The method can reduce the number of part to be abandoned due to a defect caused in the assembly process by performing a process of assembling the shaft and the fixed drum first, an area in which most defects are caused, and then proceeding to the subsequent assembly processes.

Abstract: A cassette tape ejecting apparatus has a chassis having a pin boss, a hook hole and a locking groove formed as a single body, a cassette housing installed on the chassis to be transferred to a tape insertion position and a tape ejection position, a cassette tape being mounted thereon, a locking lever being installed on the cassette housing, and having a locking protrusion hooked on the looking groove of the chassis when the cassette housing is transferred to the tape insertion position, an eject lever installed on the chassis to be rotated through the pin boss of the chassis in the forward/backward direction unlocks the locking protrusion from the locking groove of the chassis to eject the cassette tape, and a cassette switch turned on/off by the forward/backward rotation of the eject lever, for detecting ejection of the cassette tape.

Abstract: A magnetic recording and reading apparatus includes a noise preventing member provided to at least one of a deck and a holder to cover an upper side of a head drum. Noise generated by the contact between the head drum and the magnetic tape is substantially prevented from being transmitted outside of the magnetic recording and reading apparatus and to a microphone in recording operation, thereby improving the quality of recorded sound.

Abstract: A reel brake assembly for a magnetic recording/reading apparatus comprises a sub-deck slidably disposed on a main-deck in which a head drum is mounted, a reel table rotatably disposed in the sub-deck, for selectively driving a tape reel of a tape cassette, a brake unit pivotably disposed on the sub-deck, for selectively braking the reel table, and a cam gear rotated by a driving force of a driving motor, for moving the sub-deck to load and unload the sub-deck. The brake unit is selectively brought into contact with and separated from the reel table in relation to movement of the cam gear when the sub-deck is loaded and unloaded.

Abstract: A pinch roller unit of a magnetic recording/reading apparatus disposed on a main deck on which a head drum and a capstan are disposed to move in association with a sub-deck which is disposed to slide on the main deck. The pinch roller unit operates to bring a tape into close contact with the capstan, and comprises a pivoting lever rotatably disposed on the main deck to pivot towards the capstan in relation to movement of the sub-deck being loaded, a pinch roller rotatably disposed at an end of the pivoting lever and brought into contact with the capstan at the time of loading process, and a torsion spring stressed by being pushed by the sliding member sliding along the left and right directions of the main deck for pushing the pivoting lever towards the capstan.

Abstract: An improved magnetic tape guiding device for use with a magnetic tape transport system of a tape recorder and the like, and a method for using the same. The magnetic tape guiding system of the tape recorder transport system has a supply reel pole base assembly having a slant pole with a first guide unit having portions formed at both ends of the slant pole to function as a conventional roller for regulating upward and downward movement of the upper and lower edges of a moving magnetic tape, and a tension pole assembly having a tension pole with a second guide unit having portions formed at both ends of the tension pole to function as a conventional impedance roller for regulating upward and downward movement of the upper and lower edges of the moving magnetic tape. This arrangement can thus achieve 2-dimensional plane-traveling of the magnetic tape while also reducing the number of the parts of the guiding system.
