    Abstract: PURPOSE: To constitute a small-sized, lightweight device by providing two loading rings which rotate in the opposite direction, two tape guide blocks provided with guide posts, and a block guiding member which guides the movement of one tape guide block.
    CONSTITUTION: The loading rings 67 and 68 are supported freely rotatably on the top surface of a chassis 16 and rotates in the opposite direction. Those loading rings 67 and 68 are arranged concentrically at different heights outside of a drum base 42. One tape guide block 90 is provided with guide posts 93 and 94, and the other guide block 91 is provided with guide posts 128 and 129. A magnetic tape is wound around a drum 57 through those guide posts. Further, a tape guide block 91 is fitted to the upper loading ring 67, and the tape guide block 90 is supported on guide block guide members 85 and 85' movably and linked to the lower loading ring 68.

    Abstract: PURPOSE:To attain consecutive recording from the stop mode or after tape change by bringing the mode to a temporary reproducing state ahead the recording, taking timing by a reproducing control pulse obtained in this case so as to stop the tape temporarily, taking the timing by a recording control pulse so as to start the tape and also bring the mode to the recording mode. CONSTITUTION:When a recording button is depressed in the state of the stop mode, a trigger pulse TG2 is obtained, the pulse is delayed by a delay circuit 41 for a prescribed amount, a brake-off signal BOFF is obtained from a monostable multivibrator 30, an ON-signal PON of a pinch roller 10 is obtained from a monostable multivibrator 40 at the same time as brake-off, a pinch roller 10 is pressed to the capstan 9 side and the feeding of a tape 1 is started. When the carrying of the tape 1 is started, a reproducing control pulse CTp is counted by a counter 49, and when the count value reaches a prescribed value, the brake is turned on, the pinch roller 10 is turned off and the tape is stopped temporarily. The recording state is attained at the temporary stop state by attaining the synchronism by a control signal to be recorded.

    Abstract: PURPOSE:To reduce remarkably a space required for the storage of a magnetic tape by fitting one of two tape reels attachably and detachably to a cassette case. CONSTITUTION:The winding side tape reel 3 is contained in a part stepping aside one side in the inside of the cassette case 2 and the reel cassette 4 is loaded from the bottom face attachably and detachably. The supply tape reel 6 wound on the magnetic tape 5 is contained in the reel cassette 4, and when the tape cassette 1 is used as a whole, the reel cassette 4 is loaded to the cassette case 2, the magnetic tape 5 is drawn out of the reel cassette 4, and the tip is locked to the winding reel 3 through the front face of the cassette case 2. The front face of the reel case 12 is covered by a front cover 7 freely opened/ closed.

    Abstract: PURPOSE:To improve a space factor by attaching tape guide blocks to semiring gears so that moving locus of these semiring gears overlap each other. CONSTITUTION:A semiring gear 6 has a front end part 6c placed under and near a position control plate 34a and has a rear end part 6d detained by a guide member 60. A semiring gear 5 has always the outside peripheral part held between a position control plate 33b and a position control plate 33c of a detaining block 33, and the semiring 6 has always the outside peripheral part held between a position control plate 33a and the position control plate 33b of the detaining block 33. Semiring gears 5 and 6 are turned at about 96 deg. clockwise and counterclockwise respectively to move from returning positions, indicated by alternate long and short dash lines to going positions indicated by solid lines to that their moving locus overlap each other.

    Abstract: PURPOSE:To decrease a rotary angle which functions to separate a cassette lid from the upper end of a rotary drum and to attain the miniaturization of a recording/reproducing device without damaging a magnetic tape, by tilting the upper part of the rotary drum toward a cassette at a prescribed angle. CONSTITUTION:A cassette C is loaded on the 1st position by a cassette loading mechanism, and lead-out posts 2 and 3 are set within an opening part O for lead-out of a loading tape T. Then the cassette C is loaded by the loading mechanism toward a rotary drum 1, i.e., up to the 2nd position. In this case, the position of the upper end of the drum 1 opposite to a back lid BL of a cassette lid L is lowered since the drum 1 is tilted at an angle alpha. Therefore the rotary angle functioning to separate the lid L from the upper end of the drum 1 is reduced to decrease the dead space for rotation of the lid L. Furthermore, the application efficiency of the dead space is improved since the drum 1 is set close to the cassette C. This can decrease the side of a recording/ reproducing device in both the height and the depth.
