Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine storage player which facilitates a magazine eject operation.

[0002]

2. Description of the Related Art A magazine storage player that selects and reproduces a predetermined disc from a magazine that stores a plurality of discs such as CDs and LDs is used as a vehicle-mounted device. In this type of player, a magazine storage space is provided inside the device body, and the selected disc is taken out of the magazine and moved in the pickup direction.

The opening of the magazine housing space is covered with a lid to prevent foreign matter from entering from the outside. As the lid, a type that slides in the direction of the front of the device body, a type that undulates forward, and the like are adopted. When replacing the stored magazine, the lid is moved to open the opening of the magazine storage space. Then, by pressing the eject button, the magazine is ejected from the magazine storage space.

If the lid is not sufficiently moved in the opening direction when the magazine is ejected, the ejected magazine collides with the lid and smooth removal of the magazine becomes impossible. Further, repeated collisions may cause failure, damage, etc. in the magazine, device body, and the like.

Therefore, in order to enable the operation of the eject button only after the lid is completely moved in the opening direction,
For example, as shown in FIG. 1, it is known that the positional relationship between the lid and the eject button is set so that the eject button appears at the fully opened position of the lid. In this magazine storage player, a lid 2 that slides in the front direction of the device body 1 is attached to the device body 1. The magazine storage space 3 is normally covered with a lid 2 in order to prevent foreign matter from entering.

When a new magazine 4 is loaded, the lid 2 is slid as shown by the arrow in FIG. 1A to open the magazine storage space 3. Then, the magazine 4 having the disc to be reproduced is inserted into the magazine storage space 3. Further, when taking out the stored magazine 4, the lid 2 is moved to the fully open position, and the device main body 1
The eject button 5 provided on the side is exposed.
Then, as shown in FIG. 1C, the eject button 5 is pressed to eject the magazine 4.

The eject button 5 is provided at a position that appears only when the lid body 2 is at the fully open position. That is, the eject button 5 cannot be operated when the lid body 2 is open halfway. Therefore, when the eject button 5 is pressed to eject the magazine 4, the magazine storage space 3 is sufficiently released, and the magazine 4 being ejected collides with the back surface of the lid body 2,
It does not get caught on the edge of the lid 2.

[0008]

[Problems to be Solved by the Invention] In this system, the magazine 4
When ejecting, it is necessary to slide the lid 2 and press the eject button 5. Further, since the eject button 5 is provided in such a positional relationship that it is exposed at the fully opened position of the lid body 2, the design is such that the edge portion of the fully opened lid body 2 faces right next to the eject button 5. Therefore, the fingertip that tries to press the eject button 5 is easily caught on the edge of the lid 2. That is, the eject mechanism shown in FIG. 1 has a problem in operability, and cannot eject the magazine 4 smoothly.

Poor operability poses a serious problem when the magazine storage player is used in an automobile. For example, even if a person who is driving a car tries to exchange a magazine, two types of operations are required and it is not easy to press the eject button 5, so that magazine exchange while driving is extremely dangerous. Become. Further, even when a person other than the driver exchanges the magazine, it is required to confirm and press the eject button 5 in a dark car.

The present invention has been devised in order to solve such a problem, and an object thereof is to enable smooth ejecting and exchanging of a magazine by activating the eject function by opening and closing the lid. And

[0011]

In order to achieve the object, a magazine storage player according to the present invention has a magazine storage space which is opened in front of the main body and a main body of the main body so as to cover the opening of the magazine storage space. A lid that opens and closes the opening, a lid detector provided on a movement path of the lid, and an eject mechanism that is driven based on detection of a predetermined portion of the lid by the lid detector. And an eject operation is automatically performed when the lid moves to the fully open position.

[0012]

[Operation] The lid mounted on the player main body prevents foreign matter from entering the inside of the main body when fully closed, and also confirms the type of magazine stored in the open state and It has functions such as exchanging. In the present invention, it is easy to confirm the type and exchange the magazine by allowing the lid to take two types of positions, the open state and the fully open state, up to the point where there is no hindrance to the insertion and ejection of the magazine. .. When the lid is moved to the fully open position, the movement of the lid is detected by the lid detector of the eject mechanism, and the magazine is automatically ejected. That is, the magazine is ejected by only one operation of moving the lid in the opening direction.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. Embodiment 1 This embodiment is an example applied to a magazine storage player in which a slide type lid is attached to a device body.

The device body 10 is provided with a lid 20 slidable in the frontal direction as shown in FIGS. The device body 10 has a casing formed by a top plate 11, a bottom plate 12, a left side plate 13, a right side plate 14, a front plate 15 and a back plate 16 into a box shape. An opening is formed on the left side of the front plate 15 and faces the magazine storage space 17. A mechanism 18 such as a pickup and a clamper is built in the device body 10 on the right side of the magazine housing space 11.

The front side of the top plate 11 and the bottom plate 12 are bent to form guide groove portions 11a and 12a. The guide groove portions 11a and 12a extend in the front direction, and
Guide ridges 2 formed by bending the upper and lower sides of the
1, 22 are fitted together. Also, on the front surface of the lid 20,
Opening / closing ribs 23, 24 are formed on both left and right sides.

When the magazine storage space 11 is opened from the state shown in FIG. 2 in which the magazine storage space 11 is closed, one of the opening / closing ribs 23 and 24 is operated with a fingertip, and the guide ridges are guided along the guide groove portions 11a and 12a. The lid 20 is slid by sliding 21 and 22. As a result, the magazine housing space 17 is opened as shown in FIG. As a means for facilitating opening and closing, ribs 23 and 24 may be provided on both left and right sides of the lid body 20, and ribs or irregularities may be formed at appropriate places.

The slide system shown in the drawings does not restrict the present invention, and the lid body 20 may be moved in the front or the vertical direction.
Various other methods can be adopted as means for sliding the. For example, when a guide groove extending in the frontal direction is provided on the front surface side of the device body 10 and a protrusion that fits into this guide groove is formed on the back surface of the lid body 20, the thickness of the lid body 20 can be reduced, and the device body can be reduced. It becomes a sense of unity with 10.

A state in which the lid 20 is in a half-open state is shown by a solid line in FIG. In this state, the magazine storage space 11 is already open to the point where there is no hindrance to the insertion and ejection of the magazine, and the stored magazine can be taken out. It is also possible to determine the type of magazine stored. After completely opening the magazine storage space 11, the lid 20 can be further slid rightward to the position shown by the dotted line.

In the present embodiment, the switching stroke S is set between the solid line position and the dotted line position, and the lid body 2 extends to the dotted line position.
A lid detector 30 for detecting the end of the lid 20 is provided so that the eject mechanism is switched on while 0 is moved. Further, in order to maintain the lid body 20 at the solid line position,
It is preferable to provide a click mechanism 40.

The lid detector 30 includes a right side plate 14 and a front plate 1.
The eject switch 31 is provided in a space formed between the eject switch 31 and the switch 5. That is, as shown in FIG. 5 (b), the front end portion of the right side plate 14 is bent into a U-shape to form the outer side wall portion 14a, the front side wall portion 14b, and the inner side wall portion 14c,
It surrounds the eject switch 31 fixed to the front plate 15. The distance from the inner wall portion 14c to the right end surface of the casing is slightly smaller than the distance from the side surface 25a of the raised portion 25 formed on the back surface of the lid body 20 in the vertical direction to the right end portion of the lid body 20.

The eject switch 31 has a fixed contact 32 and a movable contact 33 extending downward, and is connected upward to a drive control circuit such as a motor of the eject mechanism 34. The movable contact 33 is opposed to the flange portion 35 a of the presser 35. The pusher 35 has an inner wall 14c.
It has a hollow head portion 35b to be inserted into the hole portion formed in. Then, the flange portion 35a is pressed against the inner surface of the inner wall portion 14c in a steady state by the return spring 36 stretched between the inner surface of the hollow head portion 35b and the inner surface of the outer wall portion 14a.

Although details of the eject mechanism 34 are omitted,
For example, a method in which the locking claw is retracted by a signal from the eject switch 31 so that the compressed state of the spring compressed by the force when the magazine is loaded in the magazine storage space 17 is released, and a predetermined motor is used for eject operation. A method of issuing a drive command is adopted.

When the lid 20 reaches the fully open position shown by the dotted line in FIG. 4, the side surface 25a of the raised portion 25 has the inner wall portion 14c.
6B, the hollow head portion 35b of the pressing element 35 slightly protrudes from the inner side wall portion 14c as shown in FIG. 6B. At this time, the end surface 20a of the lid 20 is aligned with the right side plate 14, and the opening of the magazine storage space 17 is completely opened from the lid 20. In order to maintain the fully opened state of the lid body 20 in a good posture, it is preferable to form a single or a plurality of support protrusions 14d having a size corresponding to the protrusion amount of the hollow head portion 35b on the inner wall portion 14c.

The click mechanism 40 is provided with a mover 42 which is inserted through a compression spring 41 into a hole 25b opened at the bottom of the raised portion 25. On the other hand, in the upper surface 12b of the guide groove portion 12a, the locking hole 12 into which the lower end of the mover 42 is fitted.
c is formed. The mover 42 and the locking hole 12c are
The lid 20 and the guide groove portion 12a are provided in such a positional relationship that they coincide with each other when the lid 20 is open to the point where it does not hinder the insertion and ejection of the magazine shown by the solid line in FIG.

In the fully closed state shown in FIG. 2, the lid 20 completely closes the magazine storage space 11 to prevent foreign matter from entering. When the lid body 20 is moved rightward from this state, the guide protrusions 21 and 22 are inserted into the guide groove portions 11a and 12a.
The lid 20 is slid in a state in which is fitted. Here, the mover 42 slides on the upper surface 12b of the guide groove portion 12a while being biased by the compression spring 41 when the lid body 20 shown by the solid line in FIG. 4 is at a position other than the click position.
In other words, the engaging groove 22 and the mover 42 form the guide groove portion 1
Since the lid 20 moves while sandwiching 2a from both sides, the sliding operation becomes smooth.

When the lid 20 slides to the click position shown by the solid line in FIG. 4, the mover 4 is inserted into the locking hole 12c.
2 matches. Therefore, the mover 42, which is biased by the compression spring 41, has a locking hole 12c as shown in FIG.
Fit in. As a result, the opened state is maintained up to the point where the insertion and ejection of the magazine shown by the solid line in FIG. The click mechanism 40 is also effective in preventing the lid body 20 from moving to the fully open position when the lid body 20 is accidentally opened by an external force such as vibration.

When the opening force applied to the lid 20 exceeds the elastic force of the compression spring 41, the compression spring 41 contracts and the mover 42 retracts from the locking hole 12c. And the lid 2
0 slides further to the right, and the side surface 25a of the raised portion 25 provided on the back surface side of the lid 20 is pressed against the hollow head portion 35b of the presser 35 as shown in FIG. 6B. As a result, the pusher 35 moves in the same direction as the sliding direction of the lid 20, and the movable contact 33 is moved by the flange portion 35a.
Transform. The deformed movable contact 33 corresponds to the fixed contact 32.
It is detected that the end of the lid 20 has reached a predetermined position. At this time, the side surface 25 a of the raised portion 25 is pressed by the pressing element 3.
5 and the support protrusion 14d, the posture of the lid 20 in a fully opened state is stable.

The detection result is output to the eject drive section as an electric signal. As a result, the magazine storage space 11
The magazine is ejected from. It is also possible to mechanically transmit the movement of the pressing element 35 to the eject mechanism without using an electric signal. For example, when a spring that is compressed when a magazine is loaded in the magazine storage space 11 is adopted, an interlocking mechanism is interposed between the locking claw that maintains the spring in a compressed state and the pressing element 35, and It is also possible to perform the eject operation by retracting the locking claw based on the movement and releasing the spring from the compressed state.

Further, in the above example, the lid detector 30 and the click mechanism 40 are provided at the end portions of the device body 10 and the lid 20. However, without being restricted by this, the lid detector 30 and the click mechanism 40 can be provided at appropriate positions other than the end portion as long as they are in contact with the movement trajectory of the lid 20.

In this way, the lid 20 is slid 1
By operation, the magazine storage space 11 is opened and the stored magazines are ejected. That is, the movement of the lid 2 and the pressing of the eject button 5 described in FIG.
The type of operation is unnecessary, and the magazine storage player has excellent operability. Further, since the slide of the lid 20 is temporarily stopped at the click position, it is possible to confirm when the lid 20 is fully opened, and a reliable eject operation is performed. Moreover, even if the lid 20 is opened unexpectedly by an external force such as vibration, the lid 20 does not move to the fully open position.

Embodiment 2 This embodiment is an example applied to a magazine accommodating player having a front-opening type lid, and is adopted when there is a spatial margin in front of the player main body.

The front-opening type lid 50 is pivotally supported by a rotary shaft 19 provided in the front direction of the apparatus body 10. The device body 10 has a built-in mechanism 18.
The portions of the front plate 15 that form the edges of the magazine storage space 17 are stoppers 15a and 15b. The stopper may be formed at the front end portions of the top plate 11 and the bottom plate 12. Further, in order to prevent the lid 20 from opening too much, the bottom plate 1
A stopper 12c is provided at the front end portion of 2. On the other hand,
A finger hook 27 for facilitating the opening / closing operation is formed on the upper front surface of the lid 20.

When the lid 20 is closed, FIG.
As shown in (b), the lid 20 is attached to the stoppers 15a and 15b.
The back surfaces of the lids abut, and the lid body 20 is maintained in the closed posture. When the lid 20 is rotated from the fully closed state to open the magazine storage space, the lid 20 reaches the fully open position shown by the dotted line through the click position shown by the solid line in FIG. 7C. The switching stroke S is set between the click position and the fully open position.

When the stopper 15b is formed on the front plate 15, as shown in FIG. 8, the support projection 12b located slightly apart from the back surface of the stopper 15b is erected from the bottom plate 12. Then, the eject switch 51 is arranged in the gap between the stopper 15b and the support protrusion 12b. The eject switch 51 extends the fixed contact 52 and the movable contact 53 downward as in the first embodiment, and is connected to the motor of the eject mechanism 54 and the like upward.

A slight gap is provided between the stopper 15a of the front plate 15 and the support projection 12b of the bottom plate 12, and the sliding member 55 is disposed in this gap so as to be slidable in the depth direction. The sliding member 55 includes a pressing flange 55a and an engaging protrusion 55b at the front end and the depth end, respectively. Then, the return flange 56 stretched between the pressing flange portion 55a and the support protrusion 12b presses the pressing flange portion 55a against the back surface of the stopper 15b. Further, the engaging projection 15b of the sliding member 55 is caught on the step portion of the stopper 12c, and the sliding member 55 is prevented from jumping out.

A blind hole 15c is formed in the stopper 15b at a position near the rotary shaft 19. A pressure ball 58 is fitted into the blind hole 15c via a compression spring 57.

The lower end of the lid 20 is formed in an arc shape with the rotating shaft 19 as the center, and a full closing engagement hole 61, a click engagement hole 62 and a pressing piece 63 are provided on the peripheral surface thereof.
The engagement holes 61 and 62 are large enough to accommodate a part of the pressing ball 58. The pressing piece 63 engages with the engaging projection 55b of the sliding member 55 when the lid 20 is laid down to the fully open position.
It is set to the position where it hits. At this time, the lid 2
Since the front surface of 0 contacts the stopper 12c, the lid 20 does not rotate further.

When the magazine storage space 17 is completely covered with the lid 20, the lid 20 assumes the posture shown in FIG. 8 (a). At this time, the pressing ball 58 is biased by the compression spring 57 and is pushed into the fully closing engagement hole 61. Since the elastic force of the compression spring 57, which is pressed by the pressing ball 58, acts on the lid 20, the lid 20 is maintained in the fully closed position shown in FIG. 8A even if an external force such as some vibration is applied.

When the magazine storage space is opened from the fully closed state, a finger is put on the finger hook portion 27 and a force exceeding the elastic force of the compression spring 57 is applied. As a result, the compression spring 57 contracts, and the engagement state between the fully closing engagement hole 57 and the pressing ball 58 is released. The lid 20 rotates in the front opening direction around the rotation shaft 19, and the pressing ball 58 slides on the lower end surface of the lid 20.

When the rotation of the lid 20 progresses and the pressing ball 58 coincides with the click engaging hole 62, the pressing ball 58 is moved by the compression spring 57 as shown in FIG. 8B. It is pushed out from the blind hole 15c and fitted into the click engaging hole 62. As a result, the lid body 20 has a click posture in which the lid body 20 is open to a position where it does not hinder the insertion and ejection of the magazine.

When a large force is further applied to the lid 20,
The engagement state between the click engagement hole 62 and the pressing ball 58 is released, and the lid body 20 rotates in the fully open direction. Then, as shown in FIG. 8C, the pressing piece 63 abuts on the engaging projection 55b of the sliding member 55 and pushes the sliding member 55 in the depth direction. Pushing flange portion 55 of sliding member 55 pushed in
The a contacts the movable contact 53 and deforms the movable contact 53. When the amount of deformation exceeds the set value, the movable contact 53 comes into contact with the fixed contact 52, and a command signal for ejecting the magazine from the magazine storage space 17 is output to the eject mechanism 54.

Thus, the lid 20 is opened to the fully open position of FIG. 8C through the click position shown in FIG. 8B. Therefore, even if the lid 20 in the state of FIG. 8A is opened by some external force, the movement in the opening direction is as shown in FIG.
It is temporarily stopped at the click position in (b). Therefore, the magazine storage space 17 is inadvertently opened, and foreign matter is prevented from entering the magazine storage space 17 or popping out of the magazine from the magazine storage space 17.

Temporarily stopping the lid 20 at the click position is also effective for confirming the full opening operation of the magazine storage space 17. That is, the fact that the pressing ball 58 is pushed into the click engaging hole 62 is transmitted as a reaction force to the fingertip that opens the lid 20. Therefore, after confirming the reaction force, the lid body 20 is further moved in the fully open direction to enable a reliable eject operation.

[0044]

As described above, in the magazine storage player of the present invention, the magazine stored in the main body is ejected only by opening / closing the lid. That is, since the eject is easily performed without the need to perform the two types of operations of opening the lid and pressing the eject button as in the conventional case, the player is easy to use.
