Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc storage magazine mounted on a disc player having an autochanger function.

[0002]

[Prior art]

 In recent car audio systems and the like, disc playback devices with an auto changer function have become popular. The disc reproducing apparatus is equipped with a disc storing magazine in which a plurality of discs are stored in advance. After that, when a predetermined operation is performed, the disc transfer mechanism in the disc reproducing device searches for one desired disc in the magazine, pulls this disc out of the magazine and carries it to the disc playing section, and then the reproducing operation is performed. It is supposed to be done.

As a disc storage magazine to be mounted in such a disc reproducing apparatus, there is a type in which a disc is stored while being supported by a tray. FIG. 5 is a perspective view showing a disc storage magazine of such a type, in which a pair of vertical side plates 2 and 3 forming the box-shaped case 1 are provided on the inner surfaces with guide projections of equal height so as to face each other. Articles 2A, 2B, 2C, ... And 3A, 3B, 3C, ... Are provided, and are configured to guide and store a plurality of trays 5.

On the other hand, a storage recess 5 a for holding the disc 4 is formed in the tray 5, and when the disc 4 is set in the storage recess 5 a, both ends of the tray 5 are inside the case 1. The disc 4 is accommodated in the magazine by being inserted in the direction of the arrow in the figure while being guided by a pair of guide ridges facing each other. FIG. 5 shows the case where one disc 4 is stored as an example, but the magazine can store a number of discs corresponding to a plurality of pairs of guide protrusions 2A to 2E and 3A to 3E at one time. ing. The disc 4 set on the tray 5 can be manually inserted / removed according to the user's request.

[0005]

[Problems to be solved by the device]

 By the way, in the conventional disc storage magazine, when the desired disc 4 is stored in the magazine, the tray 5 cannot be securely stored between the pair of guide ridges facing each other, and the tray 5 is erroneously stored between the different guide ridges. There is a problem that it is easy.

That is, since the end positions in the horizontal direction of the plurality of pairs of the guide ridges are the same on the disc insertion side, the tray 5 on which the disc 4 is set is guided by the guide ridges 2 A, 2 B ,. When they are housed between 3A, 3B ... As shown in FIG. 6, it often happens that they are housed by mistake between the guide ridges (for example, 2A, 3B) having different steps that do not face each other at the same height. When the tray 5 is stored in the magazine in a tilted state as described above, the search operation and the withdrawal operation by the autochanger are not performed smoothly, and for example, there is a problem that the tray 5 collides with the disk transfer mechanism in the device. Occur. Therefore, it is necessary to remove the magazine from the disc reproducing apparatus again and store the tray 5 in the magazine again in an accurate positional relationship.

The present invention has been made to address the above-mentioned problems, and it is possible to reliably store a tray on which a disk is set between a pair of guide ridges facing each other while maintaining an accurate positional relationship. The purpose is to provide a disc storage magazine.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a disc storage magazine in which a plurality of pairs of guide ridges facing each other are equidistantly provided on the inner surface of a pair of vertical side plates forming a case. This is characterized in that the end portions in the horizontal direction on the disc insertion side of the pair of guide ridges adjacent in the vertical direction are different from each other.

[0009]

[Operation] Since a plurality of pairs of guide ridges vertically adjacent to each other have different horizontal end positions on the disc insertion side, when the tray on which the disc is set is stored in the magazine, It is possible to prevent both ends of the tray from being stored between the different guide ridges. Therefore, the tray can be reliably housed between the pair of guide ridges facing each other while maintaining the accurate positional relationship.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of a disc storage magazine of the present invention, and shows a structure capable of storing six discs at a time as an example. Reference numeral 1 is a box-shaped case, and on the inner surfaces of a pair of vertical side plates 2 and 3 which form the case 1, there are equal height guide ridges 2A, 2B, 2C, 2D, 2E and 3A, 3B, 3C, 3D and 3E are provided. Here, the end positions in the horizontal direction on the disc insertion side of each of the guide protrusions 2A to 2E and 3A to 3E are formed such that the lower ones protrude toward the disc insertion side along the vertical direction. That is, the end positions in the horizontal direction of the guide ridges that are adjacent to each other in the vertical direction are all different.

The respective guide ridges 2A to 2E and 3A to 3E face each other in this order as shown in FIG. 2, and 2A and 3A are the first stage, and 2B and 3B are the second stage. 2C and 3C form the third stage, 2D and 3D form the fourth stage, 2E and 3E form the fifth stage, and the bottom plate 1A of case 1 forms the sixth stage. In total, 6 discs 4 can be stored. The horizontal end positions of the guide ridges facing each other are set to be equal. The number of disks to be stored can be arbitrarily set depending on the number of guide ridges.

According to this embodiment, when the tray 5 having the disks 4 set therein is housed in the magazine, the tray 5 is housed between the guide ridges which are not opposed to each other as shown in FIG. In this case, since the end portions in the horizontal direction of the adjacent guide ridges in each step are different from each other, the end portion of the tray 5 collides with one of the left and right guide ridges to prevent its insertion. Only when the tray 5 is accommodated between the pair of guide ridges facing each other, the tray 5 is guided by the pair of guide ridges and smoothly accommodated. Therefore, the tray 5 on which the disk 4 is set can be reliably housed between the pair of guide ridges facing each other while maintaining an accurate positional relationship.

FIG. 3 is a side sectional view showing a second embodiment of the present invention. Similar to the first embodiment, the pair of vertical side plates 2 and 3 forming the case 1 are provided with guide ridges 2A to 2E and 3A to 3E of equal height which face each other. The end positions in the horizontal direction of the guide ridges facing each other are set to be equal to each other, and the end positions are formed so as to project from the central part to the upper and lower ends toward the disc insertion side along the vertical direction. ing.

Also in this second embodiment, since the end positions in the horizontal direction of the guide ridges adjacent to each other are different, for the same reason as in the first embodiment, there are differences in which they do not face each other. Since the storage of the tray 5 between the guide ridges is prevented, the same effect can be obtained.

FIG. 4 shows a third embodiment of the present invention, in which the end portions in the horizontal direction of the guide ridges, which are provided at equal heights so as to face each other, are set equal to each other, and The part position is formed so that the length is repeated step by step along the vertical direction. Also in the third embodiment, the same effect can be obtained for the same reason as in the first and second embodiments.

[0016]

[Effect of device]

 As described above, according to the present invention, among the plural pairs of guide ridges, which are vertically adjacent to each other, the end positions in the horizontal direction on the disc insertion side are made different, so that the disc is set. The tray will not be stored in the magazine in a tilted state by being guided by the guide ridges on the right and left sides. Therefore, the tray can be securely housed between the pair of guide ridges opposed to each other while maintaining the accurate positional relationship, and troubles such as defective drawing of the tray can be prevented.
