れる。Prior Art> As shown in FIG. 1, a conventional cassette loading/unloading device has a swinging arm 1 pivoted on one side of a seven-frame frame 1 by a pivot 11.
At the tip of 0, attach the central part of the two sides of Kasenthorg 4 to the pivot 1
2, and horizontally pivotally supported, and the Kasenthorug 4
A sliding rod 5 is attached to the side surface of the frame 1, and includes an actuating piece 6 facing into the holder 4 and a pin 7 that fits into a hook-shaped hole 2 formed in the side surface of the frame 1. A spring ≦3 is provided between the pin 8 protruding from the side surface of the holder 4, and the sliding rod 5 is always actuated in the direction of the arrow J, and the hook-shaped hole 2 is inserted through the pin 7. Insert and remove the cassette from the holder 4 through the horizontally long hole D.
3, insert a cassette (not shown) from the insertion/ejection port 3 in the direction of the arrow, and push it forward by the drive 1 of the pull-in roll 16. In the final movement, the inner end surface of the cassette By pushing the actuating piece 6 against the spring 9, the pin 7 of the sliding rod 5J moves to the end of the horizontally long hole of the hook-shaped hole 2, and is at the starting end position of the vertical hole. Then, the holder 4 is allowed to descend. Therefore, when the holder 4 starts to descend slightly due to its own weight, the swing arm 10, and the weight of the cassette, etc., the electric motor 17 sends an appropriate transmission (via several mechanisms to the spiral cam plate 14 which is already rotating). The entry portion of the cam groove 15 meets the roll 13 pivotally mounted on the swing arm 10, and the arm 10 is forcibly rotated downward by the spiral cam plate 14 via the roll 13. Accordingly, the cassette holder 4 is housed in a predetermined position.

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 first move smoothly along the hook-shaped hole 2. Since the weight of the swinging arm 10, cassette, etc. is supported by the bin 7 at the horizontally long hole of the hook-shaped hole 2, the bin 7
The sliding resistance is large due to the contact friction between the hook-shaped hole 2 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 the final movement pushes the sliding rod 5; had the disadvantage of requiring a large rotational force.

A sliding rod 23 having a bending actuating piece 24'' facing into the holder 4 through an opening 4'' provided at the right end and a braking piece 24 bent outward on the upper edge near the right end is attached to the left and right front surfaces of the holder 4. The guide rods 8, 8 protruding from the sides and the elongated hole 8' formed in the sliding rod 23
. The sliding rod 23 is always pressed to the left, that is, in the direction of ejecting the cassette. Furthermore, the release mechanism and the blocking mechanism are opened by an interlocking mechanism (reactivation) that receives power from a drive source and interlocks the two mechanisms. The cam plate 14 and the friction transmission plate 34 are connected to the cylindrical shaft 33 and the cam plate 14 and the friction transmission plate 34, which are rotated through a mechanism, are appropriately transmitted from the electric motor 17 set at the right end of the frame 18.
is pivotally mounted on the curved surface of the frame 18, and the transmission plate 3
4 has a bent hooking piece 35 that faces into the frame 18 from an arcuate hole 22 provided near the right end of the frame and that abuts and hooks onto the upper surface of the brake piece 24 formed on the sliding rod 23. A connecting rod 30 is connected between the transmission plate 34 and the blocking plate 27 to prevent the rotation when the transmission plate 34 rotates within the allowable range of the arcuate hole 22.

のカセット引込ロール１６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, we will look at the mutual state of each mechanism when the cassette is not inserted into the holder 4. The sliding rod 23 is pulled toward the cassette insertion/ejection port 3 by the spring 9, and the locking piece 35 of the transmission plate 34 comes into contact with the upper surface of the brake piece 24 to stop the rotation of the transmission plate 34. Furthermore, in this state, the blocking plate 27 is moving in the direction of the cassette insertion/ejection port 3 similarly to the sliding rod 23, and the swing arm 1 is attached to the upper surface of the blocking protrusion 26 of the blocking plate 27.
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 (not shown) of the electric 8!17 is turned off. is set and drives the electric ff117. 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 ohm speed reducer, a gear, etc. At the same time, the cassette drawing roll 16 on the upper edge of the frame 18 is rotated via a pulley 37 coaxial with the meshing gear 36 and a belt 38.

端の枢軸１２と阻止突片２６との接触を解除する。That is, the direction of rotation of the roll 16 is the direction in which the cassette is drawn into the holder 4, so that the cassette is pulled into the roll 16.
When the cassettes are inserted into the frame 18 until they are inserted into the frame 18, the cassettes are sequentially fed into the frame 18 by the rotation of the amnesty roll 16 which presses against the upper surface of the roll 16, and the tip of the cassette eventually slides inwardly protruding from the side surface of the holder 4. Rod 23
The sliding rod 23 comes into contact with the actuating piece 24' against the upper 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 receives the rotational force of the cam plate 14, which is rotated by the driving force of the electric motor 177>-, and immediately rotates by the allowable range of the arcuate hole 22, and accordingly, the blocking plate 27 rotates the connecting rod 30. Then, the cam plate 14 is moved by an amount equivalent to the rotation (in the direction of arrow C in FIG. 8), and the contact between the pivot 12 at the tip of the swing arm 10 and the blocking protrusion 26 is released.

ダ４は所定位置に静１６される。Therefore, the pivot shaft 12 is now in a state where it can move downward into the notched groove 26. Since the weight of the cassette, holder, arm, etc. has been supported by the blocking protrusion 26, this is combined with the release operation. The swinging arm 10 starts to descend, and when it has descended slightly, the roll 13 pivoted in the middle of the swinging arm 10 is rotated (while being rolled up into the entrance of the spiral groove 15 in the waiting cam plate 14). Thereafter, the roll 13 is forced to move downward by the spiral groove 15, and the cassette holder 4 is held stationary 16 at a predetermined position.
上記においてカム板１４は電動機１７によって連続回転
せしめられるが伝動板３４が摺動杆２３の制動片３４と
の間に介在した摩擦部材によってスリップせしめカム板
１４の連続回転を吸収させるものであ、る。In the above, the cam plate 14 is continuously rotated by the electric motor 17, but the transmission plate 34 is caused to slip by a friction member interposed between the brake piece 34 of the sliding rod 23 and the continuous rotation of the cam plate 14 is absorbed. Ru.

促すものである。As described above, the braking action of the interlocking mechanism is released by the operation of storing the cassette in the holder 4, 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.

きる。<Effects of the Invention> The present invention has the following two configurations and functions.
Since the sliding rod 23 is supported on the freely sliding blocking plate 27 attached to the front surface of the frame 18 until the four sliding operations for releasing the sliding rod 23 are completed, it is different from the conventional method. In this case, excessive contact friction is not generated at the contact portion between the sliding rod 23 and the guide bottles 8, 8, and as a result, the sliding movement of the sliding rod 23 is only caused by the force that resists the tension spring. It becomes extremely light, and when pulling in the cassette with the o-le 16,
The burden placed on the final operation can be significantly reduced.
