Description

  The present invention relates to a DVD player in which a disc set in a tray is taken in and out from an opening, and is read and scanned in the inserted state, and in particular, two trays are put in and out from two different openings and one tray is placed. The present invention relates to a DVD player capable of storing discs.

  In general, there is one tray in which a disc is set in a DVD player and is inserted into and removed from the opening. Therefore, when the disc is replaced, the troublesome work of having to change the disc is required. There was a problem.

  The first prior art is shown in FIG. 7, FIG. 8, FIG. 9, and FIG. A single opening 105 for inserting / removing media is formed in the front operation unit 102 of the casing 101, and two drive units 106 </ b> A and 106 </ b> B having means for reproducing media are provided inside the casing 101. The drive units 106 </ b> A and 106 </ b> B are opposed to each other in the vertical direction, and can be moved up and down so that each end surface thereof is opposed to the opening 105 alternately. A guide roller 107 is provided between the opening 105 and each of the drive units 106A and 106B for transferring media. When, for example, a car navigation medium is inserted into the opening 105 with one drive unit 106A facing the opening 105, this is guided to the drive unit 106A by the guide roller 107. When the car navigation medium is played back by the drive unit 106A, the other drive unit 106B can be moved to a position facing the opening 105, and another medium such as a CD can be attached to the drive unit 106B and played back. (For example, refer to Patent Document 1).

  However, in this case, only one opening 105 is provided, and the two drive units 106A and 106B for reproducing the media D1 and D2 are moved up and down to move the drive units 106A and 106B up and down. In other words, it had to be taken in and out from one opening 105. Moreover, each drive unit did not store a plurality of media.

FIG. 4A is a partial cross-sectional view showing a state in which the rod is inserted into the center hole of the disc, and FIG. 4B is a partial cross-sectional view showing a state in which the disc is chucked and lifted.

As shown in FIG. 1, the DVD player according to the present embodiment is provided with storage portions 4 and 5 into and out of the player main body 1 in which two trays 2 and 3 are put in and out, respectively, and are provided in two locations in the lateral direction. Two openings 1a and 1b for inserting and removing the trays 2 and 3 are set, and an opening / closing lid 6 is provided on the upper side of the storage unit 4 in which the left tray 2 is stored.
Further, the player main body 1 incorporates a chucking mechanism 7 (see FIGS. 3, 5, and 6) for chucking the disc D set on the tray 3 on one side. Further, the read / reproduced disc D set on the right tray 3 by the chucking mechanism 7 is gripped by the chucking mechanism 7 and transported to the left tray 2 (FIG. 2). , FIG. 3 and FIG. 4). Then, the disk D chucked in the right tray 3 is moved leftward by the chucking mechanism 7 and the moving mechanism 8 so that a plurality of disks D are stored in the left tray 2.

  As shown in FIGS. 2 (a), 2 (b) and 4, the moving mechanism 8 described above straddles the two trays 2 and 3 in the player main body 1, and reads and reproduces the disc D at the center. A horizontally long guide plate 9 in which a long hole 9a for moving the left and right trays 2 is formed, and an elongated hole 12a in which four guide claws 10 provided on the upper surface of the guide plate 9 are provided in a pair of front and rear. 12b, and is moved by being guided and moved. The moving member 12 has rack teeth 11 formed on one side in the longitudinal direction, and the motor 14 has a gear 13 that meshes with the rack teeth 11 and moves the moving member 12. . The elongated holes 12a and 12b are provided from the right edge of the moving member 12 to the vicinity of the left edge.

As shown in FIGS. 3, 5, 6 (a) and 6 (b), the chucking mechanism 7 described above includes a rod 15 made of a magnet disposed at the center and a rod 15 for moving the rod 15 upward. The coil 16 and the lower side of the rod 15 are fully fitted up and down, and when the rod 15 is lifted upward by magnetism, the lower end 17a is opened and the disk D set in the tray 3 is lifted upward The rod-shaped body 17 is provided on the upper side of the rod 15, and is composed of a large coil 18 for moving the rod 15, the cylindrical body 17 and the coil 16 up and down magnetically.
A metal plate 19 is attached to the upper end of the rod 15 in a horizontal direction, and substantially L-shaped guide pieces 18 a and 18 b that are suspended from left and right sides of the large coil 18 in a pair of left and right holes 19 a and 19 b of the plate 19. Is inserted, and is guided by the guide pieces 18a and 18b, so that the plate member 19 is moved up and down by the magnetism of the large coil 18, and the rod 15 is moved up and down.

Next, the operation of the DVD player having the above configuration will be described.
As shown in FIG. 3, in a state where the trays 2 and 3 are stored in the storage units 4 and 5 in the player body 1, the reading scan of the disk D set in the right tray 3 is finished, and Due to the magnetism of the large coil 18 of the king mechanism 7, the rod 15 is lowered integrally with the cylindrical body 17 from the state of FIG. 5 to the state of FIG. 6, and the rod 15 and the cylindrical body 17 are inserted into the center hole d of the disk D. The Next, the rod 15 made of a magnet is moved upward by the magnetism of the coil 16, the lower end portion 17a of the cylindrical body 17 is opened, and the disk D is chucked as shown in FIG. 6B.
The rod 15 and the cylindrical body 17 are lifted by the magnetism of the large coil 18, and the disk D is moved above the right tray 3.

In this state, when the motor 14 is driven, the gear 13 is rotated, and when the gear 13 and the rack teeth 11 are engaged, the moving member 12 moves to the left from the state of FIG. 2A, and the state of FIG. That is, it moves to the upper side of the left tray 2. In this state, the magnetism of the large coil 18 is released, and the rod 15 and the cylindrical body 17 are lowered to the tray 2 side. Then, the magnetism of the coil 16 is released and the rod 15 is lowered, the lower end portion 17a of the cylindrical body 17 is closed, the chucking of the disk D is removed, and the disk D is stored in the tray 2 on the left side. .
Then, when the left tray 2 is taken out from the opening 1a of the player body 1, the stored disc D can be taken out. Alternatively, the disk D in the internal tray 2 can be taken out from the upper side by opening the opening / closing lid 6.
The right tray 3 is taken out from the other opening 1 b of the player body 1, so that another disc D can be set in the tray 3. Further, the right side tray 3 is again accommodated in the accommodating portion 5 in the player body 1 through the opening 1b, whereby another disk D set on the tray 3 is read and scanned.

According to this embodiment, the chucking mechanism 7 and the moving mechanism 8 can automatically move the disk D from the right tray 3 to the left tray 2, and the plurality of disks D after reading and reproduction can be moved to the left side. It can be stored in the tray 2, and it is not necessary to change the disk D when replacing the disk D, and the disk D can be replaced easily. Furthermore, the disk D can be taken out from the upper side by opening the opening / closing lid 6.
Further, the rod 15 can be automatically inserted into the center hole d of the disk D set on the tray 3 by the magnetism of the large coil 18 of the chucking mechanism 7, and then the rod 15 is directed upward by the magnetism of the coil 16. The disk D can be lifted from the tray 3 by moving and opening the lower end of the cylindrical body 17 to chuck the disk D reliably and easily.

Further, the moving member 12 having the rack teeth 11 meshing with the gear 13 rotated by the driving of the motor 14 of the moving mechanism 8 can be moved from the right tray 3 side to the left tray 2 side. The disc D after reading and reproduction can be easily and reliably moved from the right tray 3 to the left tray 2. Then, after moving, the disk D can be stored in the left tray 2.
Moreover, a pair of elongate holes 12a, 12b for engaging the guide claws 10 of the guide plate 9 are provided in the front-rear direction from the right edge to the vicinity of the left edge. Can be smoothly guided to the other tray side 3 or 2.
