る。<Prior Art> As shown in FIG. 1, a conventional cassette loading/unloading device has a swinging arm 10 which is pivoted on one side of a frame 1 with a pivot 11, and the center of the upper surface of a cassette holder 4 is attached to the tip of a swing arm 10 with a pivot 12. The cassette holder 4 is pivoted and supported horizontally, and the side surface of the cassette holder 4 is provided with an operating piece 6 that faces into the holder 4 and a pin 7 that fits into a hook-shaped hole 2 formed on the side surface of the frame 1. The sliding rod 5 is attached, and a spring 9 is stretched between the pin 7 and a pin 8 protruding from the side surface of the holder 4, so that the sliding rod 5 is always acted in the direction opposite to the arrow. 7
Hold the holder 4 at the same height as the cassette insertion/ejection port 3 through the horizontally long hole of the hook-shaped hole 2, insert a cassette (not shown) from the insertion/ejection port 3 in the direction of arrow A,
When the cassette is pushed by the drive of the pull-in roll 16, the inner end surface of the cassette pushes the actuating piece 6 against the spring 9, and the pin 7 on the sliding rod 5 becomes hook-shaped. The horizontally elongated hole portion of the hole 2 is moved to the terminal end, and the holder 4 is in a state where it is at the starting end position of the vertically elongated hole portion and is allowed to descend. Therefore, holder 4 has its own weight,
When the swinging arm 10 starts to descend slightly due to the weight of the cassette, etc., the entrance of the cam groove 15 in the spiral cam plate 14 which is already being rotated by the electric motor 17 via an appropriate transmission mechanism and the swinging movement. A roll 13 pivotally mounted on the arm 10 meets the arm 10.
Since the cassette holder 4 is forcibly rotated downward by the spiral cam plate 14 via the roll 13, the cassette holder 4 is housed in a predetermined position.

求さる欠点を有していた。 In order to lower and store the cassette holder 4 to a predetermined position in this manner, it is important that the sliding rod 5 moves smoothly along the hook-shaped hole 2. 10. Since the weight of the cassette etc. is supported by the pin 7 in the horizontally long hole of the hook-shaped hole 2, the sliding resistance is large due to the contact friction between the pin 7 and the hook-shaped hole 2. As a result, the cassette is inserted through the insertion/ejection port 3, and when it comes into contact with the roll 16, the cassette is moved inward by the roll 16, and its final movement pushes the sliding rod 5. The roll 16 had the drawback of requiring a large rotational force.

を同時に回転せしめる。<Operation> The device of the present invention is constructed as described above. Next, we will discuss the series of operations of each of these mechanisms. First, let us look at the mutual state of each mechanism when the cassette is not inserted into the holder 4. Sliding rod 23
is pulled toward the cassette insertion/ejection port 3 by the spring 9, and a transmission plate 34 is placed on the upper surface of the brake piece 24.
The locking piece 35 contacts the transmission plate 34 to prevent rotation, and in this state, the blocking plate 27
is moving in the direction of the cassette insertion/ejection opening 3 in the same way as the sliding rod 23, and the blocking protrusion 26 of the blocking plate 27
The outer end of the pivot shaft 12 at the tip of the swing arm 10 is supported on the upper surface, and in this state, when the cassette is inserted from the cassette insertion/ejection port 3 of the frame 18 to a certain depth in the direction of arrow A, the power switch of the electric motor 17 (not shown) is pressed. ) is set to drive the electric motor 17.
Therefore, the rotation is caused to rotate the cam plate 14 at a constant speed in a predetermined direction (direction of arrow B) through a transmission mechanism such as a belt, a worm reducer, a gear, etc., and the rotation is further transmitted from the gear 14' of the cam plate 14. The cassette drawing roll 16 on the upper edge of the frame 18 is connected to this through a pulley 37 coaxial with the meshing gear 36 and a belt 38.
rotate at the same time.

枢軸１２と阻止突片２６との接触を解除する。 That is, the rotational direction of the roll 16 is the direction in which the cassette is drawn into the holder 4, so that when the cassette is inserted to the position where it contacts the roll 16, the roll 16 is pressed against the upper surface of the cassette. Therefore, the cassettes are fed into the frame 18 one after another, and the tips of the cassettes eventually come into contact with the operating piece 24' of the sliding rod 23 that projects inwardly from the side surface of the holder 4, and the sliding rod 23 is moved against the tension spring 9.
is pushed in the direction of arrow A. (See Fig. 3) As a result, the brake piece 24, which had hitherto been restraining the rotation of the locking piece 35 on the transmission plate 34, moves, and in order to release the blocking action on the locking piece 35, the transmission plate 34 is a cam plate 1 which is rotated by the driving force from the electric motor 17
4, the blocking plate 27 immediately rotates by the allowable range of the arcuate hole 22, and along with this, the blocking plate 27 rotates through the connecting rod 30 by an amount equivalent to the rotation of the cam plate 14 (in the direction of arrow C in FIG. 8). ) to release the contact between the pivot 12 at the tip of the swinging arm 10 and the blocking protrusion 26.

つて該ロール１３は下降動作が強制されてカセツ
トホルダ４は所定位置に静置される。 Therefore, the pivot shaft 12 is in a state where it can be lowered toward the notch groove 26', and since the weight of the cassette, holder, arm, etc. has been supported on the blocking protrusion 26, the pivot shaft 12 swings in conjunction with the release operation. The movable arm 10 starts to descend, and when it has descended slightly, the roll 13 pivoted in the middle of the movable arm 10 rotates and waits until the spiral groove 15 in the cam plate 14 is reached.
After that, the roll 13 is forced to move downward by the spiral groove 15, and the cassette holder 4 is left stationary at a predetermined position.

させるものである。 In the above, the cam plate 14 is rotated in conjunction with the electric motor 17, but the sliding rod 23 of the transmission plate 34
While being stopped by the brake piece 24, the friction member interposed between the cam plate 14 and the transmission plate 34 absorbs the continuous rotation of the cam plate 14 by causing it to slip.

して該ホルダ４の下降動作を促すものである。 As described above, when the cassette is stored in the holder 4, the braking action of the interlocking mechanism is released, and at the same time, the power from the electric motor 17 is transmitted to the blocking plate 27, thereby releasing the action of preventing the cassette holder 4 from descending. This prompts the holder 4 to move downward.

る。<Effects of the Invention> The present invention has the configuration and operation described above, and the tip shaft 12 of the swing arm 10 that supports the cassette holder 4 is placed on the freely slidable blocking plate 27 mounted on the front surface of the frame 18. In order to support the sliding rod 23 until the sliding movement for release is completed, the present invention provides means for preventing the downward movement caused by the weight of the cassette and cassette holder; Since the cassette detection means does not need to be driven by the cassette's horizontal feed roller, the load acting on the cassette feed roller is significantly reduced, and the cassette detection means does not need to be driven by the cassette horizontal feed roller. Since the cassette lowering prevention means is then released, switching between the horizontal feeding operation and the vertical vertical movement of the cassette is extremely smooth.
従つて電動機１７の駆動力も少なくて済む為に
小型化でき、又各機構への動作も円滑に伝達させ
る効果を有する。 Therefore, since the driving force of the electric motor 17 is small, the size can be reduced, and the operation can be smoothly transmitted to each mechanism.
