Description

  The present invention raises and lowers an elevator equipped with an optical pickup, a disk table or the like to a desired disk position, and moves a recording and / or reproducing apparatus such as a disk autochanger that performs recording and / or reproduction, and the elevator or the like. The present invention relates to a moving operation mechanism suitable for use.

  As a disk autochanger, those shown in FIGS. 36 to 37 are known. The disk autochanger 101 is arranged on the side of the disk cartridge 103 in which a plurality of disk storage portions 103a for storing the disks 102 are provided in layers, and recording and / or reproduction of the disk 102 is performed.

By the way, the conventional disk changer 101 has the following problems.
(1) The closer the inclination angle θ of the operation groove 114 is to 90 °, the greater the elevator 104 can be lifted with a small amount of movement of the moving plate 113, but the load on the moving plate 113 is reduced. It becomes large and it becomes difficult to move the moving plate 113 smoothly. On the other hand, the smaller the inclination angle θ, the smoother the moving plate 113 moves, but the moving stroke amount must be increased, and a space for securing the moving stroke amount is required. It becomes an obstacle to downsizing.
(2) When the linearly inclined operation groove 114 as shown in FIGS. 36 to 37 is used, in order to stop at the position of each disk accommodating portion 103a to 103n of the disk cartridge 103, The accuracy of the position detection sensor must be increased. Therefore, as shown in FIG. 38, horizontal groove portions 114a are provided at the positions of the operation grooves 114 corresponding to the respective disk housing portions 103a, and the accuracy of the position detection sensor is compensated by these horizontal groove portions 114a. A disk changer has also been developed in which the elevator 104 can be accurately stopped at a desired position of the disk accommodating portion 103a. However, the operation groove 114 and the moving plate 113 can be obtained by providing the horizontal groove portion 113a. In order to secure a moving stroke amount, a larger space is required.

  The present invention solves the above-described conventional problems and provides an elevating mechanism capable of avoiding an increase in the size of a disk changer even when a horizontal groove as described above is provided in the middle of the operation groove. It was made for the purpose.

  The present invention crosses the guide groove provided on the fixed plate and the operation groove provided on the moving plate, supports the elevator at the intersection of the guide groove and the operation groove, and moves the moving plate, thereby In the raising / lowering mechanism configured to raise and lower the elevator along the guide groove by the operation groove, the moving plate is divided into a plurality of pieces, and the divided moving plates are intermittently operated one by one. First, when the first moving plate is moved in one direction, the elevator moves from the first position to the second position in the operation groove of the first moving plate, and then the second sheet is moved. When the plate is moved, the elevator is moved from the second position to the third position in the operation groove of the second moving plate.

The lifting mechanism and disk changer device of the present invention have the following effects.
(1) Since the moving plate provided with the operating groove is divided into a plurality of pieces and these are moved intermittently, the moving distance of the moving plate and the operating groove is set as compared with the case of moving one moving plate. Can be reduced.
(2) Since the moving distance of the moving plate and the operation groove can be reduced, the apparatus or the like can be downsized.
(3) Since the moving distance of the moving plate and the operation groove can be reduced, horizontal grooves and inclined grooves are alternately formed in the operation groove, and the lifted body is stopped by the horizontal groove. It is possible to improve the positioning accuracy of the lifted body.
(4) Since the positioning accuracy can be improved by the horizontal groove portion, it is not necessary to use a highly accurate position detection sensor, and the cost can be reduced.
(5) Since the moving plate drive mechanism is configured to intermittently move a plurality of moving plates using a rotating cam, compared to a case where a plurality of moving plates are moved intermittently using a plurality of motors, The number of parts and the number of parts can be reduced.
