JPH03286467A - Disk unloading device at power failure for disk loading device - Google Patents

Abstract

PURPOSE:To easily take out a disk even at the power failure and to make the capacitor of large capacity and the disassembling and the assembling of a chassis, etc., unnecessary by providing a gear fitted on a rotatable shaft and capable of engaging with one gear of a gear mechanism and an energizing member to retract the gear to a position not to engage with one gear in the gear mechanism. CONSTITUTION:When power failure breaks out at the time of reproduction, etc., when a tray 1 is placed at the loading position, and in addition, a disk loaded in the tray 2 is desired to take out during the power failure, a driver 13 is inserted into a bit at the front end of the shaft 10. Next, the driver 13 is pushed, and the shaft 10 is pushed in backward against a spring 14, and after a bevel gear 9 is engaged with the bevel gear 8, the shaft 10 is rotated by the driver 13. The rotation of the shaft 10 is transmitted to a rack 1a through the bevel gears 9, 8, the gear 3, worms 4, 5, and the gear 6, and the tray 1 comes to be moved toward an ejecting position. Thus, even at the time of the power failure, the disk can be easily taken out, and the capacitor of large capacity for driving a motor at the time of the power failure and work such as the disassembling and the assembling of the chassis, etc., are made unnecessary.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for recording digital signals on a digital disc directly or by inserting a jacket containing the disc through a slot provided in a housing. In a disc playback device, when a power outage occurs while the disc loading device is at the disc loading position, the disc loading device loads the disc into the transport means at the eject position and transports the disc to the loading position where recording and playback can be performed on the disc. The disk loading device is operated to move the conveyance means to the eject position,
The present invention relates to a disc ejecting device that allows discs to be ejected.

[Conventional technology]

Conventionally, in order to eject a disc during a power outage, a voltage was stored in a capacitor when electricity was applied, and that voltage was used to drive a motor to operate a disc loading device and move the transport means to the eject position. There is.

[Problem to be solved by the invention]

In such a disk ejecting device during a power outage, a relatively large amount of electric power is required to drive the motor, so the capacitor used has a large capacity, which requires space and increases cost. There was a drawback.

In addition, in such a disc loading device that does not have a disc ejecting device during a power outage, the bonnet, panel,
The disk was removed by removing the chassis, manually rotating a gear driven by a motor, or disengaging the gear from the rank, and then moving the transport means to the eject position.

Therefore, there are disadvantages in that it takes time and effort to take it out, and it becomes necessary to reassemble it, which requires skill.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problem with the conventional disk ejection during power outage.The present invention moves the conveyance means to the eject position by operating from the front of the panel, and allows the disk to be easily ejected. The purpose is to eliminate the need for capacitors and to eliminate the need for disassembly and assembly of bonnets, panels, chassis, etc.

[Summary of the Invention] The present invention relates to means for a disk ejecting device during a power outage in a disk loading device in order to achieve the above-mentioned object, and is driven by a motor of a conveying means that conveys the disk between an eject position and a loading position. It is installed on the shaft exposed at the front and can be meshed with one of the gears.The biasing member is used to retract to the non-meshing position, and by operating the shaft against the biasing member, both gears are meshed, and the shaft rotates. The transport means is operated by the following steps.

5 [Embodiments of the invention] Next, an example of implementation of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a tray that can be slid back and forth with respect to the frame 2 and is loaded with a disk, and a rack 1a is formed on the negative side of the tray (FIG. 1).

3 is a gear group fixed to the shaft of the motor 17, 4 is a worm also fixed to the shaft of the motor 17, and 5 is the worm 4.
The worm gear 6 that meshes with the worm gear 5 is a gear group 6 that meshes with the worm gear 5, and the final gear 6a of the gear group meshes with the rack 1a. Accordingly, depending on the direction of rotation of the motor 17, the tray 1 is moved back from the eject position where a disc is loaded to the loading position where recording and reproduction is performed on the disc, or advanced from the loading position to the eject position. Further, a bevel gear 8 is integrally formed with the gear 7 that meshes with the final gear 3a of the gear group 3 fixed to the shaft of the motor 17 (FIG. 3).

The shaft 10 to which the bevel gear 9 meshing with the bevel gear 8 is fixed is
The shaft 10 is supported by the support plate 11 and the shaft bearing 12a of the front panel 12, and the front end of the shaft 10 is exposed on the front surface of the front panel 12, and a bit that can be rotated by a driver 13 is formed on this end surface. There is.

A spring 14 is installed between the bevel gear 9 and the support plate 11, and the biasing force of the spring 14 causes the bevel gear 9 to retreat to a position where it does not mesh with the bevel gear 8.

Further, the rack la is provided with a cam Ib, and when the tray 1 reaches the loading position, the cam lb pushes the switch 15 to operate it.

As mentioned above, this disk loading device slides the tray l depending on the rotational direction of the motor to perform loading and ejecting operations. At this time, the bevel gear 9 is not meshed with the bevel gear 8, so the shaft 10 is never rotated.

Then, when a power outage occurs during playback when the tray 1 is at the loading position, and when it is desired to take out the disc loaded in the tray 1 during the power outage, the driver 13 is inserted into the bit at the front end of the shaft 10.

Next, the driver 13 is pushed to push the shaft 10 backward against the spring 14, causing the bevel gear 9 to mesh with the bevel gear 8, and then the shaft 10 is rotated by the driver 13.

The rotation of the shaft 10 is caused by the bevel gears 9, 8, the gear 3, the worm 4,
The signal is transmitted to the rack 1a via the worm gear 5 and gear 6, and the tray 1 is moved toward the eject position.

When tray 1 reaches the eject position, the cut-out IC of tray 1 hits the stopper 16, and the tray 1
This prevents the tray 1 and its guide from being damaged.

Further, when the tray 1 is in the loading position and the shaft 10 is operated as described above to move the tray 1 to the eject position, the cam 1C is separated from the switch 15 and the cam 1C is released from the switch 15. By switching the operation, the reproduction operation is stopped.

Therefore, it is possible to prevent failures of the pickup and head mechanisms, turntables, spindle motors, etc. due to movement of the tray 1 in the eject direction during playback.

〔Effect of the invention〕

The present invention is like a ridge, so that even if there is a power outage while the conveyance means is in the loading position and recording or playback is in progress on the disk, the shaft can be operated from the front of the front panel. , the transport means can be moved to the eject position and the disc can be taken out.

Therefore, there is no need to incorporate a large-capacity capacitor or battery that can drive the motor even during a power outage, and the volume of the player can be reduced, and the cost of the capacitor and battery can be reduced.

In addition, disassembly of the bonnet and the drive mechanism of the conveyance means, such as equipment that does not have a capacitor or battery,
This eliminates the need for troublesome and skilled work such as reassembling after taking out the disk.

The mechanism is also simple, and the operation of the conveyance means when energized is as follows:
It has the effect of allowing smooth operation without any influence.
