摘要： The present invention relates to a tape simulator of a cassette tape type digital audio/video device built in the cassette tape type digital audio/video device and capable of normally operating a cassette deck player by having the tape simulator recognized as a cassette tape as reproducing voice/video digital signals recorded in the device in use of the cassette deck player. The tape simulator of the cassette tape type digital audio/video device according to the present invention comprises left and right reel hubs inserted in both driving reels of the cassette deck player to be rotated; and a rotation speed attenuating unit for attenuating the rotation speeds of the left and right reel hubs to at a predetermined rate by providing resistance to the left and right reel hubs rotated by the driving reels. The rotation speed attenuating unit includes a center gear simultaneously meshed with the left and right reel hubs; a torque producing unit for applying a certain torque to the center gear, or an idle gear meshed with the left and right reel hubs to run idle; and a rubber roller being in rolling contact with the pinch roller of the cassette deck player and meshed with the idle gear. With the structure, overall problems can be solved due to the use of a belt since the use of the belt is excluded.

摘要： A magnetic recording/reproduction apparatus of the present invention, which records/reproduces information on/from a magnetic tape by passing the tape around a rotary head cylinder having a rotary head for a predetermined arc, includes: a capstan shaft; a pinch roller; a first reel base rotatably attached to a shaft; a second reel base rotatably attached to a shaft; and an idler supported swingably to swing to the second reel base when the capstan is rotated in a first direction and to the first reel base when the capstan shaft is rotated in a second direction, wherein the idler includes a gear portion which rotates in association with the rotation of the capstan shaft. The above components of the magnetic recording/reproduction apparatus are situated in such a manner that when the running of a magnetic tape is to be shifted from a first direction to a second direction, the rotation of the capstan shaft, in the first direction stops, the pinch roller moves away from the capstan shaft, the capstan shaft is rotated in the second direction by a predetermined amount so that the idler swings to the first reel base, the capstan shaft stops again, the pinch roller presses the magnetic tape against the capstan shaft, and the capstan shaft is rotated again in the second direction and the gear portion to be coupled with the first reel base, the gear portion rotating the first reel base in a direction in which the magnetic tape is wound onto the first reel.

摘要： To reduce the number of parts and simplify the structure by permitting the forward-rotation components and the reverse-rotation components to share a mechanism of transmitting the driving force to a pair of reel blocks 42F,42R. A pair of capstans 41F,41R respectively serving for forward rotation and reverse rotation and a pair of reel blocks 42F,42R respectively serving for forward rotation and reverse rotation are provided. One of the capstans, i. e. the capstan 41F, is provided with a low-speed gear 48, while the other capstan 41R is provided with a high-speed gear 49. The reel blocks 42F,42R are respectively provided with reel gears 50F,50R. A transmission changeover means 51 is installed to transmit the driving force from the low-speed gear 48 to the appropriate gear selected between the reel gears 50F,50R according to the direction in which the tape is run when the system is in either the forward mode or the reverse mode, and transmit the driving force from the high-speed gear 49 to the appropriate gear selected between the reel gears 50F,50R according to the direction of rotation of the tape when the system is in either the fast-forward mode or the rewinding mode.
