セットがひっかかり実用上問題がある。As shown in Figure 1, conventional cassette loading devices have a long horizontal movement distance, and the fulcrum of rotation of the cassette door is set at a position where the tip of the cassette door and one end of the cassette do not overlap when viewed from the horizontal direction. . For this reason, the cassette loading device has become large, and the portable VT is designed to be small and lightweight.
It was inappropriate for R. In addition, because it is small and lightweight, the horizontal movement distance is shortened and the fulcrum of the cassette door is set at a position where the tip of the cassette door and one end of the cassette overlap when viewed from the horizontal direction. If the cassette door is opened or closed after the cassette has moved horizontally or vertically, the cassette door and the cassette may get caught, which poses a practical problem.

が加わり圧着される。FIG. 3 shows the cassette ejection position, and FIG. 4 shows the cassette normal mounting position. The cassette mounting device has a gate-shaped structure with a pair of side plates 3 arranged on both sides and connected by a top plate 11 on the upper surface. The side plate 3 has an L for holding and guiding the cassette holder 1.
A groove 3a is provided. A bottle 4 mounted on the cassette holder 1 is slidably passed through the L-shaped groove 3a. On the right side of the side plate 3, a pulley and a gear train are provided to obtain power from the motor. A drive arm 6 is engaged with the drive gear 5, and the bin 4 of the cassette holder 1 protruding from the side plate 3 is connected to the drive arm 6. The cassette is inserted, the switch is turned on, the motor is driven, and the cassette is installed at the installation position shown in FIG. The drive gear 5 and the drive arm 6 are connected by a torsion spring, so even if the cassette is seated in the positioning boss on the chassis, the drive gear rotates, which causes the torsion spring to deflect, and as a result, force is applied to the cassette. It is added and crimped.

The door arm 9 moves according to the cam groove 7a and the cassette door 1
Open and close 0. The power gear 7 rotates approximately 30 degrees from the time the cassette is installed to the completion of crimping, and during this rotation, the cassette door 1
The cam groove 74 is set so that 0 opens and closes.

Even if L is set, the cassette can be mounted without the cassette door 10 and the cassette 2 getting caught. As a result, by setting the rotational fulcrum 10eL as shown in the figure, the horizontal movement distance of the tray, cassette, and tray 2 is shortened. By setting the cassette before the cassette is transferred in the direction, a small and lightweight cassette mounting device becomes possible.
