DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge loading apparatus for loading a disk cartridge containing a disk serving as an information recording medium into a recording and / or reproducing apparatus.

[0002]

2. Description of the Related Art Heretofore, as a loading device for loading a disk cartridge containing a disk serving as a recording medium of an information signal into a recording and / or reproducing device, a device provided with a cartridge holder into which a disk cartridge is inserted and held is known. Used. The cartridge holder is configured to record or record information signals by scanning a signal recording area of a rotating drive mechanism mounted on the rotating drive mechanism and rotating the disk mounted on the rotary drive mechanism with a light beam. The optical pickup device for performing reproduction is provided on a chassis provided with the optical pickup device, and is movably supported between a loading position close to the rotation driving mechanism and an unloading position separated from the rotation driving mechanism.

In this disc cartridge loading apparatus, the operation of moving the cartridge holder between the loading position and the unloading position is performed by moving a cam plate associated with the cartridge holder by a drive motor.

Some cartridge holders of this disc cartridge loading device have a cartridge lock mechanism for holding a disc cartridge inserted in the cartridge holder. The cartridge lock mechanism is slidably mounted on a cartridge holder and has a disk cartridge detection lever. The disk cartridge detection lever is slid by being pressed by a disk cartridge inserted into the cartridge holder. The cartridge holder is provided with a cartridge lock lever that is rotated in conjunction with the cartridge detection lever. The cartridge lock lever is provided with a cartridge lock pin for locking the disk cartridge at a predetermined position of the cartridge holder.

In the cartridge lock mechanism configured as described above, when a disk cartridge is inserted into the cartridge holder and the cartridge detection lever is slid, the cartridge lock lever is rotated, and the cartridge lock pin engages with the disk cartridge. This locks the disk cartridge in the cartridge holder. When the cartridge holder is moved in a direction away from the loading position, the cartridge lock lever is rotated by the drive motor to release the lock on the disk cartridge. The rotation operation of the cartridge lock lever by the drive motor is
This is performed by transmitting the driving force of the driving motor by a driving force transmission mechanism such as a link mechanism.

[0006]

Incidentally, the disk cartridge loading device provided with the above-described cartridge lock mechanism has an unloading operation of moving the cartridge holder in a direction away from the loading position and releasing the lock on the disk cartridge. For this purpose, a lock release operation for rotating the cartridge lock lever is performed via separate driving force transmission mechanisms. Therefore, in this disc cartridge loading device, unless the components constituting each driving force transmission mechanism are formed with high precision, there is a possibility that the timing of the unloading operation and the lock release operation cannot be accurately regulated. If the timings of the unloading operation and the unlocking operation are shifted, the unlocking operation is not performed even when the unloading operation is completed, and the ejecting operation for discharging the disk cartridge from the cartridge holder cannot be performed smoothly. An unlocking operation is performed before the completion of the unloading operation, and the position of the disk cartridge with respect to the cartridge holder may be shifted, resulting in an inoperable state.

In addition, since this disk cartridge loading device needs to be provided with a plurality of driving force transmission mechanisms, the structure becomes complicated and it is difficult not only to reduce the size of the device itself but also to manufacture it easily. Is difficult to do.

Therefore, the present invention has been proposed in view of the above-mentioned circumstances, and it is possible to accurately regulate the timing of the unloading operation of the disk cartridge and the operation of releasing the lock on the disk cartridge. An object of the present invention is to provide a disk cartridge loading device which can perform a smooth ejecting operation, simplify the structure, reduce the size of the device itself, and can be easily manufactured.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems and to achieve the above object, the present invention provides a loading position close to a recording and / or reproducing mechanism and an unloading distance away from the recording and / or reproducing mechanism. A cartridge holder movably supported by the chassis between the cartridge holder and a disk cartridge movably attached to the cartridge holder and inserted into the cartridge holder. A cartridge lock mechanism that engages with the disk cartridge and locks the disk cartridge; and
A loading control plate for controlling the movement of the cartridge holder; and a lock release control mechanism for releasing the locking of the disk cartridge by the cartridge lock mechanism in cooperation with the movement direction of the loading control plate.

When the disc cartridge is inserted into the cartridge holder, the disc cartridge is locked by the cartridge lock mechanism, and the loading control plate is moved in a direction for moving the cartridge holder to the loading position. When the loading control plate holds the cartridge lock mechanism in a state where the disc cartridge is locked, the loading control plate is moved in a direction of moving the cartridge holder from the loading position to the unloading position. The lock release member is moved in cooperation with the movement of the loading control plate, and the lock of the cartridge lock mechanism to the disk cartridge is released by the lock release control member. It is intended.

[0011]

In the disk cartridge loading device according to the present invention, when the disk cartridge is inserted into the cartridge holder, the disk cartridge is locked by the cartridge lock mechanism, and the loading control plate moves in the direction of moving the cartridge holder to the loading position. The loading control plate keeps the cartridge lock mechanism in a state where the disk cartridge is locked. Then, when the loading control plate is moved in the direction of moving the cartridge holder from the loading position to the unloading position, the lock release member is moved in cooperation with the movement of the loading control plate,
By releasing the lock of the cartridge lock mechanism to the disk cartridge by the lock release control member, the disk cartridge can be ejected from the cartridge holder, so that the disk cartridge is unloaded and the disk cartridge is unlocked. Is prevented from shifting, and a reliable ejection operation can be performed.

[0012]
