Embodiment
Please refer to Fig. 1 and Fig. 2, shown in Figure 1 is the stereographic map that is respectively the record changer of a preferred embodiment of the present invention, and Fig. 2 is the structural drawing of enclosure of the record changer of Fig. 1.Record changer comprises a shell 1, a cassette 4, several pallets 41 and a tray locking device.Tray locking device comprises a locking piece 3 and a pulling device 2.Locking piece 3 is to be fixedly set on the shell 1.Shell 1 is to be divided into storage area and to read the district.Pulling device 2 is the districts that read that are disposed in the shell 1, and pulling device 2 is to move up and down in shell 1.Cassette 4 is the storage areas that are installed in the shell 1, and cassette 4 inside can hold several pallets 41.And have the carriage (not shown) between cassette 4 and the pallet 41, making pallet 41 is that selecting type is arranged at the storage area in the shell 1 and reads district and removable in cassette.Pulling device 2 is to be used for pallet 41 is pulled to reading the district from storage area, that is the positions in cassette 4 are pulled to the position of reading the discs data.In addition, cassette 4 can take out in shell 1, so that place or change discs on pallet 41.In addition, as Fig. 2 and shown in Figure 3, pulling device 2 is to move up and down to choose pallet in shell 1, and aims at the pallet choose so that the pallet that is selected is drawn out to from storage area reads the district.
Please refer to Fig. 4 to Fig. 6, illustrate the locking piece in the tray locking device in the preferred embodiment of the present invention.Locking piece 3 has a fixed part 31 and is used for locking piece 3 is fixed on the shell 1; And several locking pin 32 can be fixed corresponding pallet 41 respectively.In addition, on shell 1, has an opening 12 (as shown in Figure 1), and on the position of cassette 4, have several perforates 42 (as shown in Figure 2) with respect to several locking pin 32, the opening 12 that locking pin 32 can be seen through on the shell 1 stretches into shell 1 inside, and passes corresponding perforate 42 respectively so that the pallet in the cassette 4 41 is locked.
In the present embodiment, locking piece 3 can be fixed on the outside of shell 1, and the opening 12 on shell 1 makes locking pin 32 stretch into the inside of shell 1, and the inside that need not be installed on shell 1 increases the complexity of record changer internal mechanism or interfere mutually with other mechanism, and can improve the convenience in the assembling.
Please refer to Fig. 7, illustrate the stereographic map of the pulling device of Fig. 1.In the present embodiment, tray locking device comprises again and backs down part 21 stationary installations on pulling device 2, and backs down part 21 and have a teat 211, and teat 211 is to be used for the locking pin 32 of locking pallet 41 is backed down, to discharge pallet 41.Owing to back down part 21 devices on pulling device 2, when pulling device 2 moves up and down, back down part 21 also along with pulling device 2 moves up and down.Therefore move to when aiming at the pallet of choosing when pulling device 2, back down the teat 211 of part 21 and also aim at the locking pin that locks the pallet of choosing, and will lock pin and back down.As shown in Figure 9, the pallet that this can be chosen of pulling device 2 is pulled to from storage area and reads the district.
In the present embodiment, owing to back down part 21 stationary installations on pulling device 2 and along with pulling device 2 moves up and down, when pulling device 2 is aimed at the pallet of desiring to choose, back down part 21 and also aim at the locking pin be locked on this pallet of choosing simultaneously, and should lock pin and back down by backing down teat 211 on the part 21.At this moment, the pallet that all pallets in cassette 4 are only chosen is not locked in place, and other pallet is still kept blocked state.So, can avoid when pulling device 2 pallet chosen being pulled to when reading the district from storage area, other pallet of not choosing is because of vibration or impact and break away from deposit position, the record changer internal mechanism is interfered mutually, and then cause the damage of mechanism.
Please refer to Fig. 8, illustrate the structural representation of pallet among Fig. 2.In the present embodiment, each pallet 41 has a CD holder 412 again respectively in order to placing discs, and an engaging piece 411 is meshing with each other in order to the corresponding locking pin 32 with locking piece 3, makes locking pin 32 pallet 41 can be fixed in storage area, be in the cassette 4, as shown in Figure 9.
Several locking pin 32 by the locking piece 3 of present embodiment can be distinctly with each pallet 41 locking.When being pulled to the pallet of choosing from storage area, pulling device 2 desires read the district, the locking pin that backs down on the pallet that part 21 chooses this separately in pulling device 2 backs down, the locking pin and the engaging piece of the pallet of choosing are separated, discharge with the pallet that this is chosen, other pallet of not choosing then still remains on the state of locking.Thus, can avoid when pulling device 2 pallet chosen being pulled to when reading the position from deposit position, other pallet of not choosing is because of vibration or impact and breaks away from deposit position, causes the damage of record changer internal mechanism.
Can effectively limit the action of each pallet 41 by the tray locking device of the record changer of present embodiment, pallet 41 is pinned and limits its action, to prevent that pallet 41 from withdrawing from deposit position voluntarily in vibration or under impacting, influence the action of record changer internal mechanism, cause internal mechanism to damage.
The tray locking device of the disclosed record changer of the above embodiment of the present invention, can effectively limit the action of each pallet, tray locking is limited its action, to prevent that pallet from withdrawing from deposit position voluntarily in vibration or under impacting, avoid influencing the action of record changer internal mechanism and cause internal mechanism to damage.In addition, locking piece can read the position when pulling device is pulled to the pallet of choosing from deposit position individually with each pallet locking, can separately the pallet of choosing be discharged, and other pallet of not choosing then still remains on the state of locking.Thus, can avoid when pulling device the pallet chosen being pulled to when reading the position from deposit position, other pallet of not choosing is because of vibration or impact and breaks away from deposit position, causes the damage of record changer internal mechanism.Especially, the design of locking piece can't increase the complexity of record changer internal mechanism, and can improve the convenience in the assembling.
In sum; though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, therefore, protection scope of the present invention defines and is as the criterion when looking accompanying Claim book scope.
