A plurality of guide pins 72 (three in the example of FIG. 3) are arranged at a predetermined interval.
[0012]
As shown in FIG. 4, a substantially L-shaped connecting member 74 constituting a part of the urging means is disposed on the apparatus main body 50 in correspondence with the upper surface 54A and the back surface 54B of the magazine 54, and this connecting member. 74 can be brought into contact with and separated from the middle of the magazine 54 in the left-right direction (see FIG. 3). As shown in FIG. 3, a pair of guide pieces 76 are arranged on the connecting member 74 on a straight line along the front-rear direction. A pair of linear guide holes 52A along the front-rear direction are formed in the top plate 52 of the apparatus main body 50 along a front-rear direction at a portion corresponding to the guide piece 76.
[0013]
The top plate 52 is formed with a pair of straight elongated holes 52B along the front-rear direction on both the left and right sides of the guide hole 52A. The elongated holes 52B have a length that connects the ends of the pair of guide holes 52A. It has become. Further, the top plate 52 is formed with a hook portion 53 facing the long hole 52B, and the connecting member 74 facing the hook portion 53 is formed with a hook portion 78 facing the long hole 52B.
[0014]
Coiled springs 80 that constitute part of the urging means are hooked on the hook portions 53 and 78, so that the magazine 54 is always urged forward by the urging force of the springs 80. The spring 80 is set to generate a biasing force that allows the magazine 54 to be pushed out from the loading section 60 even when ten CDs 10 are stored in the magazine 54. That is, the magazine 54 is pulled out by the biasing force of the spring 80 as soon as the lock pin 66 is separated from the locking groove 56B.
[0015]
When the magazine 54 is inserted into the loading unit 60 of the apparatus main body 50, the back surface 54 </ b> B and the top surface 54 </ b> A of the magazine 54 abut against the connecting member 74 and push down the connecting member 74 against the urging force of the spring 80. Then, as shown in FIG. 5A, the lock pin 66 is inserted and locked into the locking portion 56B through the passage portion 56A.
[0016]
That is, since the lock lever 68 shown in FIG. 4 is urged to the right side by the spring 69, the lock pin 66 is positioned in the locking groove 56. Therefore, the magazine 54 is positioned on the loading unit 60 against the urging force of the spring 80.
[0017]
The CD 10 in the magazine 54 loaded in the loading unit 60 is conveyed to the reproducing unit 62 and chucked by a conveying unit (not shown). The chucked CD 10 is played back by playback means such as a pickup (not shown).
[0018]
On the other hand, in order to take out the magazine 54 from the loading section 60, an eject switch (not shown) is operated to slide the slide lever 70 shown in FIG. As shown in FIG. 5B, when the slide lever 70 slides and the lock pin 66 is separated from the locking portion 56B, the lock pin 66 faces the passage portion 56A (see FIG. 5B). The magazine 54 is pulled out from the loading section 60 while being guided by the guide pins 72 by the urging force (see FIG. 5C).
[0019]
And the connection member 74 shown in FIG. 4 stops by contacting the front-end part of a pair of guide hole 52A. The lock pin 66 slides to the right side by the biasing force of the spring 69 and returns to the initial position shown in FIG.
[0020]
[Problems to be solved by the invention]
Incidentally, as shown in FIG. 5, since the passage portion 56A is formed in a straight line along the front-rear direction, the magazine 54 is moved in the front-rear direction when the locking between the lock pin 66 and the locking portion 56B is released. Slide along (see FIGS. 5C and 5B). That is, as shown in FIG. 5B, when the lock pin 66 protrudes to the left from the engaging portion 56B, it is held at a position along the guide groove 58 of the magazine 54 as it is.
[0021]
Therefore, the lock pin 66 passes through the straight distance L2 without any obstacle, and a large urging force of the spring 80 acts on the magazine 54 and the connecting member 74. For example, when about 2 to 4 CDs 10 are stored in the magazine 54, the weight of the magazine 54 is lighter than when the magazines 54 are stored in the 10 CD 10 magazines. Extruded by.
[0022]
That is, as soon as the lock pin 66 is separated from the locking portion 56B, the magazine 54 is suddenly pushed out by the urging force of the spring 80, so that the lock pin 66 becomes free over the distance L2 (that is, what the lock pin 66 has In addition, the impact applied to the apparatus main body 50 is strengthened by the biasing force of the spring 80 shown in FIG. 3 (that is, the reaction caused by the biasing force of the spring 80).
[0023]
Therefore, the conventional autochanger is provided with a damper mechanism for mitigating the impact caused by the spring 80 to prevent impact when the magazine 54 is ejected. However, if the damper mechanism is provided, the configuration becomes complicated and expensive.
[0024]
In view of the above-described facts, the present invention is to provide an ejection mechanism that suppresses an impact when a magazine is ejected with a simple configuration.

DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show a magazine ejection mechanism according to an embodiment of the present invention. In FIG. 1, parts corresponding to those in FIG. 3 are denoted by the same reference numerals, and detailed description thereof is omitted.
[0034]
As shown in FIG. 2, the engaging means 12 formed on the back surface of the magazine 54 is arranged corresponding to the lock pin 66 and is in a direction (left / right direction) orthogonal to the pushing direction (front / rear direction) of the magazine 54. A locking portion 14 is provided, and a zigzag passage portion 16 that is continuous with the locking portion 14 and extends in the front-rear direction is provided. That is, the engaging means 12 has a groove shape, so that the lock pin 66 is inserted into the engaging means 12 and engaged.
[0035]
The passage portion 16 is formed continuously with the left end portion 14 </ b> B of the lock portion 14 so as to contact the passage portion 16 as soon as the lock pin 66 is detached from the lock portion 14. In addition, the passage portion 16 includes a slanted buffer portion 18 that is continuous to the left end portion 14B of the lock portion 14 via a groove shape along the front-rear direction that is the pushing direction of the magazine 54, and the slanted shock absorber portion 18 that faces diagonally rightward. 18 is formed of a slanted relief portion 20 that extends diagonally to the left side after 18 and an entrance / exit 22 in which a slope 22A is formed continuously to the relief portion 20.
[0036]
That is, the entrance / exit 22 is cut out at the end face of the magazine 54, and thus the lock pin 66 enters from the entrance / exit 22 through the escape portion 20 and the buffer portion 18 and is locked to the lock portion 14. On the other hand, when the locking is released, the lock pin 66 comes into contact with the buffer portion 18 and is buffered, and then is separated from the magazine 54 via the escape portion 20 and the entrance / exit 22. As shown in FIG. 1 and FIG. 2, the present embodiment is configured as described above, and the rest is the same as the example of FIG.
[0037]
Next, the operation of the ejection mechanism according to this embodiment will be described. First, an operation when the magazine 54 is pulled out from the loading unit 60 of the apparatus main body 50 will be described. In a state where the magazine 54 is locked in the loading portion 60, the lock pin 66 is locked to the lock portion 14 as shown in FIG.
[0038]
Then, when an unillustrated eject switch is operated and the slide lever 70 shown in FIG. 2B slides to the left side, the lock pin 66 is separated from the lock portion 14 and faces the passage portion 16, so that the spring 80 shown in FIG. The magazine 54 is pulled out from the loading unit 60 while being guided by the guide pins 72 by the urging force.
[0039]
That is, when the lock pin 66 is detached from the lock portion 14 as shown by the solid line in FIG. 2B , the lock pin 66 moves to the position shown by the two-dot chain line in FIG. Then, it abuts against the front end 18A of the buffer portion 18 and moves to the rear end 18C of the buffer portion 18 through the inclined surface 18B of the buffer portion 18 (see the one-dot chain line in FIG. 2B). Accordingly, as shown in FIG. 2B, the lock pin 66 slides along the buffer portion 18 from the left side to the right side.
[0040]
In this embodiment, when the lock pin 66 is disengaged from the lock portion 14, it is indicated by a two-dot chain line in FIG. 2B, which is a position that can move along the buffer portion 18 from the position indicated by the solid line in FIG. Since it immediately moves to the position and abuts against the front end 18A and the inclined surface 18B (including the rear end 18C) of the buffer portion 18, as compared with the conventional example shown in FIG. Impact by the biasing force is reduced.
[0041]
That is, in the present embodiment, the lock pin 66 is made free at the stage of the initial state where the urging force of the spring 80 is the largest (the extended state of the spring 80 when the lock pin 66 is locked to the lock portion 14). Therefore, the shock caused by the urging force of the spring 80 can be more effectively suppressed.
[0042]
According to this embodiment, since the distance L1 (see FIG. 2B) where the lock pin 66 is free becomes shorter than in the conventional case, the impact due to the urging force of the spring 80 is reduced accordingly. Therefore, according to the present embodiment, the impact at the time of ejecting the magazine 54 can be effectively buffered only by changing the groove shape of the engaging means 12, so that a conventional damper mechanism becomes unnecessary and the ejecting of the magazine 54 is eliminated. The impact at the time can be suppressed by a simple configuration.
[0043]
Further, when the magazine 54 is pushed out from the apparatus main body 50, the lock pin 66 moves to the escape portion 20 (see the two-dot chain line in FIG. 2C) and the biasing force of the spring 69 shown in FIG. To move to the slope 22A of the entrance 22 (see the one-dot chain line in FIG. 2C). When the lock pin 66 moves from the position of the inclined surface 18B of the buffer portion 18 (the position indicated by the one-dot chain line in FIG. 2B) to the escape portion 20 and the entrance / exit 22, the lock pin 66 is connected to the escape portion 20 and the entrance / exit. Move left and right along
[0044]
2C, the lock pin 66 is separated from the engaging means 12 of the magazine 54, and the magazine 54 is pushed out from the loading section 60 via the connecting member 74. As shown in FIG. Moreover, as shown in FIG. 1, the connection member 74 stops by contacting the end portions of the pair of guide holes 52A. The lock lever 68 is held at the initial position shown in FIG. 2C by the urging force of the spring 69 shown in FIG.
[0045]
Next, an operation when the magazine 54 is loaded in the loading unit 60 will be described. An arbitrary CD 10 is replaced or stored in the magazine 54 pulled out from the loading unit 60. As shown in FIG. 1, when the magazine 54 is inserted into the loading unit 60, the connecting member 74 comes into contact with the upper surface 54 </ b> A and the back surface 54 </ b> B of the magazine 54. Further, when the magazine 54 is inserted into the loading portion 60 against the urging force of the spring 80, as shown by the one-dot chain line in FIG. Abut.
[0046]
When the magazine 54 is further inserted into the loading portion 60, the lock pin 66 moves against the urging force of the spring 69 shown in FIG. 4 along the inclined surface 22A to the escape portion 20 as shown by a two-dot chain line in FIG. Transition. When the magazine 54 is further inserted into the loading unit 60, the lock pin 66 faces the lock unit 14 through the buffer unit 18 as shown in FIG. As a result, the lock pin 66 is urged to the right by the urging force of the spring 69 and moves to the lock portion 14 and is locked, so that the magazine 54 is positioned on the loading portion 60 against the urging force of the spring 80.
[0047]
In the above embodiment, the escape portion 20 is provided in the passage portion 16 in a zigzag shape. However, the passage portion according to claim 1 of the present invention is continuous from the end portion of the lock portion and is a lock portion with respect to the pushing direction of the magazine. It may be formed on a straight line in an oblique shape so as to be directed toward the end portion (that is, toward the rear oblique right side in the example of FIG. 2). In this case, when making the inclination angle of the inclined surface 18B the same as that shown in FIG. 2, it is necessary to increase the sliding amount of the lock pin 66.
[0048]
In the above embodiment, the lock pin 66 has a substantially equilateral triangular plane shape, but the lock pin of claim 4 may be, for example, a cylindrical shape. Furthermore, in the above embodiment, the connecting member 74 and the spring 80 are used as the biasing means. However, in the present invention, a coiled spring constituting a part of the biasing means may be a leaf spring or the like. Similarly, the biasing member of claim 1 may be a leaf spring or the like.
[0049]
In the above embodiment, the engaging means 12 is an example of a groove formed in the magazine 54. However, the engaging means of claim 1 is configured to attach a member provided with a lock portion and a passage portion to the slide body, for example. You may do it. Furthermore, in the above embodiment, the engaging means 12 is a groove and the locking means is a lock pin 66. However, the concave-convex relationship between the engaging means and the locking means of the present invention is the reverse of this embodiment. Anyway.
[0050]
Further, although the above embodiment is an example of a magazine ejecting mechanism applied to an autochanger for reproducing the CD 10, the present invention can be similarly applied to a magazine ejecting mechanism applied to an autochanger for reproducing a mini disk or the like. Furthermore, although the slide body is an example of the magazine 54 in the above embodiment, the slide body of the present invention can be similarly applied to, for example, a box-shaped dust portion of a vacuum cleaner.
[0051]
【The invention's effect】
As described above, according to the present invention, when the latching means is detached from the lock portion, the latch means is immediately brought into contact with the passage portion in which the buffer portion is formed. The distance is shortened, and the impact caused by the urging force of the urging means for urging the slide body can be reduced accordingly. That is, according to the present invention, the impact at the time of ejecting the slide body can be more effectively buffered by simply changing, for example, the groove shape of the engaging means, so that a conventional damper mechanism becomes unnecessary and the slide body is ejected. Can be suppressed with a simple configuration.
