Abstract: A cassette loading mechanism for loading a magnetic tape cassette, which has a front pivotal closure member openable for covering or exposing a front opening of the magnetic tape cassette, in a recording and/or reproducing apparatus includes a cassette holder which is movable between an eject position, at which the cassette can be inserted into or removed from the cassette holder, a lowered position vertically offset from the eject position, and a loaded position horizontally offset from said lowered position and at which cassette loading is completed. The upper portion of the cassette holder is covered with a cassette holder lid which has a recessed portion so that the front pivotal closure member may be moved to open in synchronism with movement of the cassette holder from the eject position to the lowered position. The cassette holder lid and the cassette holder are moved in unison.

Abstract: PURPOSE:To eliminate sag due to an unnecessary rotation and to prevent the damage of a tape by sliding the projecting part for rotation communication with spring force in a discharging direction at the time of discharging a cassette and keeping the engaging condition with a recessed part until a reel is locked. CONSTITUTION:When the phase of a recessed part 105 of a reel 102 and a projecting part 5 of a shaft part 4 is dislocated at the time of installing a tape cassette 101, a projecting part 105 and the projecting part 5 are abutted, the projecting part 5 is pushed down while a spring 6 is compressed, the projecting part 5 is rotated on an inclined surface 13 of projecting parts 104 and 5 and the position with a recessed part 104 is matched. When the recessed part 105 and the projecting part 5 are fitted, the spring 6 is compressed on the upper surface of a bearing hole 103 and the projecting part 5 is pressed down until a reel lock is released. At the time of discharging, the cassette 101 is pushed up with the spring 6, and the fitting condition of the recessed part 105 and the projected part 5 is kept untill the reel 102 is locked. Thus, the sag of the tape due to the unnecessary rotation of the reel is eliminated and the damage to the tape is prevented.

Abstract: PURPOSE:To improve the resolution of the detection of rotation by disposing a disk where an N pole and an S pole are magnetized at intervals of specified angle opposed to a rotor. CONSTITUTION:A Hall element 6 is disposed by opposed to the magnetized part of the disk 2 and it makes an output signal from a magnetism sensitive element into a pulse every change of specified amplitude to output. The output signal from the Hall element 6 is supplied to a comparator 13 through an amplifier 7 and an A/D converter 11. Plural reference values corresponding to the output signal from the converter 11 are supplied to the comparator 13 from a table 14. In the comparator 13, the output signal from the A/D converter 11 is compared with plural reference values from the table 14. When the signal coincides with them, the pulse is outputted from the comparator 13. The pulse outputted from the comparator 13 is supplied to a counter 15 and the output signal from the counter 15 is supplied to a display circuit 9 so that the display of the counter is performed. The output signal from the counter 15 is made to pass a system control circuit 10 so as to detect the abnormality, etc., of the rotation of a reel 1. Thus, the resolution of the detection of rotation can be improved without lowering rotational torque.
