(See FIG. 6).
[0023]
A transport unit 10 is supported on the main body side housing 3 so as to be movable in the vertical direction. The transport unit 10 includes a base unit 11, a picking unit 12, and supported units 13 and 13 (FIG. 4). And FIG. 5).
[0024]
A connecting shaft 14 is rotatably supported at the lower front end portion of the base portion 11 (see FIGS. 5 and 6). An auxiliary pinion 15 and a main pinion 16 are provided adjacent to the left and right at a position near the left end of the connecting shaft 14.
[0025]
The auxiliary pinion 15 is rotatably supported with respect to the connecting shaft 14, and connecting holes 15a and 15a are formed at positions opposite to the connecting shaft 14 (see FIG. 6).
[0026]
The main pinion 16 is formed thicker than the auxiliary pinion 15, and is fixed to the connecting shaft 14 by, for example, press-fitting, and cannot rotate with respect to the connecting shaft 14. The main pinion 16 is formed with connecting holes 16a, 16a on the opposite side of the connecting shaft 14, and the connecting holes 16a, 16a are smaller in diameter than the connecting holes 15a, 15a of the auxiliary pinion 15. (See FIG. 6).
[0027]
The auxiliary pinion 15 and the main pinion 16 are connected by connecting pins 17 and 17 inserted into the connecting holes 15a, 16a, 15a and 16a, and the connecting pins 17 and 17 are press-fitted into the connecting holes 16a and 16a ( (See FIG. 6). Therefore, a predetermined clearance is formed between the connecting holes 15a, 15a and the connecting pins 17, 17, and the auxiliary pinion 15 can rotate with respect to the main pinion 16 by this clearance.
[0028]
The main pinion 16 and the auxiliary pinion 15 are adjacent to the left and right adjacent to the right end of the connecting shaft 14 in the same relationship as the auxiliary pinion 15 and the main pinion 16 provided near the left end of the connecting shaft 14. Is provided. One end of a drive gear 18 is inserted into the auxiliary pinion 15 provided near the right end of the connecting shaft 14, and the drive gear 18 is connected to the main pinion 16 (see FIGS. 5 and 6). The drive gear 18 is rotated by a drive mechanism (not shown) having a drive motor provided on the base portion 11, whereby the right main pinion 16 is rotated, and the auxiliary pinions 15, 15 and the main pinion 16 are rotated by the connecting shaft 14. , 16 are rotated synchronously.
[0029]
The auxiliary pinions 15 and 15 and the main pinions 16 and 16 are formed at the same pitch, and the pitch circle of the main pinions 16 and 16 is slightly larger than the auxiliary pinions 15 and 15.
[0030]
The picking unit 12 is supported by the base unit 11 so as to be movable in the front-rear direction, and moves the disc-shaped recording medium 100 between the insertion / removal unit 6, the storage units 7, 7 or the drive units 8, 8 and the transport unit 10. It plays a role to let you exchange.
[0031]
The supported portions 13 and 13 are provided at the front end portions of the left and right side surfaces of the base portion 11, and a part of the supported portions 13 and 13 protrudes forward from the base portion 11 (see FIG. 4). The front end portions of the supported portions 13 and 13 are formed as bent portions 13a and 13a bent inward, and moving rollers 19 and 19 are rotatably supported on the front surfaces of the bent portions 13a and 13a, respectively. (See FIG. 4 and FIG. 5). Further, guide rollers 20, 20,... Are rotatably supported on the inner surface of the portion of the supported portions 13, 13 that protrudes forward (see FIG. 4).
[0032]
The transport unit 10 includes main pinions 16 and 16 meshed with the main racks 9 and 9 (see FIGS. 6 and 7), and the moving rollers 19 and 19 are in contact with the side surface of the main body side housing 3 from the outside. Guide rollers 20, 20,... Are supported on the main body side housing 3 in contact with the mutually opposing surfaces of the guide portions 5 b and 5 b of the guide rails 5 and 5 provided on the main body side housing 3 (see FIG. 4). At this time, the auxiliary pinions 15 and 15 are partly located between adjacent teeth of the main racks 9 and 9 and the auxiliary racks 4 and 4, but the main racks 9 and 9 and the auxiliary racks 4 and 4 4 is not meshed (see FIG. 7).
[0033]
As described above, the transport unit 10 is configured such that the driving gear 18 is rotated by the driving mechanism, and the main pinions 16 and 16 meshed with the main racks 9 and 9 are rotated in synchronization with each other. And the guide rollers 20, 20,... Are moved in the vertical direction with respect to the main body side housing 3 while rolling.
[0034]
Thus, in the disk transport apparatus 1, the auxiliary racks 4 and 4 and the auxiliary pinions 15 and 15 are not meshed with each other, and the main racks 9 and 9 and the main pinions 16 and 16 are meshed so that the transport unit 10 is Since it is moved, the driving force of the drive motor of the drive mechanism can be reduced accordingly, and the power consumption of the disk transport device 1 can be reduced.
[0035]
Thus, when the insertion / removal unit 6, the storage units 7, 7 or the drive units 8, 8 are removed from the main body side housing 3, the engagement between the main racks 9, 9 and the main pinions 16, 16 is released. At this time, a part of the tooth tips of the auxiliary pinions 15 and 15 are located between adjacent teeth of the auxiliary racks 4 and 4, so that the conveyance unit 10 is slightly moved downward by its own weight to assist. The pinions 15 and 15 are slightly rotated with respect to the connecting shaft 14 and the main pinions 16 and 16, and the auxiliary pinions 15 and 15 are engaged with the auxiliary racks 4 and 4 (see FIG. 8).
[0036]
Therefore, even when each mounting block of the insertion / removal unit 6, storage unit 7, 7 or drive unit 8, 8 is removed from the main body side housing 3, the transport unit 10 falls regardless of the position of the transport unit 10. It is possible to avoid damage due to the drop of the transport unit 10.
[0037]
Further, when the removed mounting block is mounted on the main body side housing 3 again, the main racks 9 and 9 and the main pinions 16 and 16 are meshed with the original meshing positions before being removed. It is possible to prevent an adverse effect on the transport operation of the disc-shaped recording medium 100.
[0038]
Further, when the removed mounting block is to be mounted on the main body side housing 3 again, the front ends of the main racks 9 and 9 and the front ends of the main pinions 16 and 16 do not interfere with each other and the mounting blocks are remounted. Can be performed properly.
[0039]
In addition, in the disk transport device 1, since the main pinions 16 and 16 and the auxiliary pinions 15 and 15 are provided on the same axis as the connecting shaft 14, the manufacturing cost can be reduced by reducing the number of parts. Can do.
[0040]
In the above, the pitch circle of the auxiliary pinions 15 and 15 is made smaller than that of the main pinions 16 and 16, and only the main pinions 16 and 16 are used when the mounting blocks are mounted on the main body side housing 3. The racks 9 and 9 are engaged with each other. For example, the pitch circles of the auxiliary pinions 15 and 15 are made the same as those of the main pinions 16 and 16, and the auxiliary blocks are mounted when the mounting blocks are mounted on the main body side housing 3. The positions of the racks 15 and 15 and the main racks 16 and 16 may be changed so that only the main pinions 16 and 16 are engaged with the main racks 9 and 9.
[0041]
In this way, the same components can be used for the auxiliary pinions 15 and 15 and the main pinions 16 and 16, and the manufacturing cost of the disk transport device 1 can be reduced by sharing the components.
[0042]
In the above, the disk transport device 1 having the insertion / removal unit 6, the storage units 7, 7, and the drive units 8, 8 is shown as each mounting block, but each mounting block is not limited to these, for example, A printer unit or the like may be provided as a mounting block.
[0043]
Further, the recording medium is not limited to the disk-shaped recording medium 100 described above, and may be a tape-shaped recording medium, a semiconductor memory, or the like.
[0044]
It should be noted that the specific shapes and structures of the respective parts shown in the above-described embodiments are merely examples of implementation in carrying out the present invention, and the technical aspects of the present invention are thereby limited. The range should not be interpreted in a limited way.
[0045]
