摘要： 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.

摘要： A mode reset method for a magnetic recording/reproducing apparatus whereby a deck is preferably reset to a predetermined mode of operation when power is applied. The method includes an initializing step and a mode reset step. Preferably, the initializing step includes substeps for driving a plunger, rotating a capstan motor to connect a transmission gear to a loading system when the power is applied, and then retracting the plunger. The mode reset step includes substeps for resetting the deck to a stop mode when the deck is in the stop mode, when the deck is between the stop mode and a playback mode, or when the deck is between the stop mode and an unloading stop mode at the time power is applied. Alternatively, the mode reset step resets the deck to the unloading stop mode, when the deck is stopped between the unloading stop mode and eject mode. During the mode reset step, operation is controlling responsive to frequency generator signals during rotation of the capstan motor, and the outputs from stop and a cassette-in sensors. The mode reset method advantageously enables the deck to recognize its own mode of operation and to prevent malfunction thereof when the power is applied. An apparatus adapted to performing the method is also described.

摘要： 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.

摘要： A reel guide apparatus of a magnetic recording/reproducing apparatus accurately seats the supply reel and take-up reel onto a lower chassis of the apparatus. The reels are installed on a slider which is lowered to the lower chassis. Holes in the slider receive reel guide units for stably guiding the reels in the vertical direction. A position determining unit on the lower chassis accurately determines the seating of the tape cassette on the lower chassis. Sensors on the reel guide units and split disc reflectors on the reels facing the sensors result in the generation of reel pulses, which are used to determine remaining tape length, etc.

摘要： A cassette lid opening and closing system for a magnetic recording and reproducing apparatus capable of opening a cassette lid during the seating of a tape cassette on a deck and closing it after the seating is accomplished, to thereby lower the height of the deck, includes a lid-open member operating link for swinging a lid-open member to open the cassette lid during the seating of a cassette holder on a slider, a lever for closing the open cassette lid by releasing a lid-pressing operation of the lid-open member when the tape cassette is moved to a seated position on a lower chassis, and a lever operator for operating the lever, so that the cassette lid is closed during recording or reproducing operation. Advantageously, a closed cassette lid allows a corresponding reduction in the size of the deck.
