A power transmission device for a tape recorder, which is capable of easily transmitting power to a tape loading unit or a reel table system, includes a loading system driving gear for transmitting power to the tape loading unit to thereby position a tape with respect to a drum, and a reel-system driving gear for driving the reel table system, in which the gears are selectively driven to receive power from the capstan motor via transmission and rotating gears operated by a magnetic force and a spring. By driving the tape loading unit and reel tables with the capstan motor, one motor can be removed to further minimize deck size.

Power transmission device for tape recorder

A tape rewinding mechanism for a magnetic recording/reproducing apparatus is disclosed in which, when ejecting the tape from the deck, the reel with the tape installed thereon is driven by a capstan motor, so that the tape can be recovered with a proper tension maintained between the tape and the drum, thereby preventing damage to the tape. A driving gear is installed on a lever of a transmitting gear which is meshed with the capstan gear, and thus, the take-up reel is driven during loading, while the supply reel is driven during an unloading. During a reproduction, the take-up reel and the supply reel are easily driven by the transmitting gear, thereby simplifying the structure of the deck.

Tape rewinding mechanism for magnetic recording/reproducing apparatus

In a magnetic recording/reproducing apparatus, an idler gear is selectively moved between controlling a take up reel and a supply reel. An idler controlling apparatus limits the swing angle of the idler to a relatively small angle when the upper chassis is being seated on the lower chassis or when the tape is being ejected. The idler controlling apparatus also permits a wide swing angle of the idler when the tape recording/reproduction operations take place. The wide swing permits the idler gear to selectively control the take up and supply reels.

Idler controlling apparatus of a magnetic recording/reproducing apparatus

A power shifting device for a magnetic recording and reproducing apparatus. The power transferring device includes a transmitting gear which is capable of being switched to selectively transmit the power of a capstan motor to the loading system or to the running system. The lower portion of the shaft of the transmitting gear is switched along a groove of the main chassis so as to be guided along the opposite walls of the groove to the exact position, so that the power is selectively transmitted to the loading system or to the running system of the apparatus.

Power transferring device for magnetic recording and reproducing

In a magnetic tape recording/reproducing apparatus, an idler moves an idler gear selectively between a supply reel and a take up reel to transfer power respectively to the reels. During loading of the tape of a cassette tape, an upper chassis, with the tape cassette and drum, is seated on a lower chassis, with the loading and travelling gearing apparatus. During seating operation, the idler is held in a central position by an idler cam having a cam surface to be out of the way of the components on the upper chassis, thereby eliminating interference with the seating operation. During normal tape running operations, the cam surface controls the movement of the idler.

A tape rewinding device for a magnetic recording and reproducing apparatus. When a tape cassette is loaded and recorded or reproduced, the tape often becomes loose within the deck. The tape rewinding device automatically recovers the loose portion of the tape during the ejecting of the tape cassette. A slider is provided with a tape recovering apparatus that includes a plurality of gears, and the tape recovering means is meshed with a rack gear. During the ejecting of the tape cassette, the gears are made to revolve by being meshed with the rack gear, and the rotating gear rotates a supply reel, thereby rewinding the loosen tape.
