Abstract

PURPOSE:To access data, and record and reproduce data by driving a loading mechanism by an auxiliary power source when the electric power supply from a main power source to the optical disk device is cut off. CONSTITUTION:While the electric power is supplied from the main power source 5, the loading mechanism part 4 is driven with the electric power from the power source 5. When the electric power is not supplied from the power source 5, on the other hand, the electric power is supplied from the auxiliary power source 6 with a cartridge ejection button 3 pressed and the camera part is driven. Then a cartridge 1 is loaded in or unloaded out of a cartridge insertion slot 2 and the cartridge 1 which is confined to the optical disk device is ejected. Further, data can be accessed, written, and reproduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply means for an optical disk device.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram of an optical disk device described in, for example, "Signal processing means in optical recording" (February 20, 1991; issued by Trikeps Co., Ltd.). In the figure, 1 is a cartridge for storing an optical disk, 2 is a cartridge insertion port for inserting / removing the optical disk cartridge 1 into / from the optical disk apparatus, 3 is a cartridge eject button for sending a signal for ejecting the inserted cartridge 1, and 4 is a cartridge 1 A loading mechanism section 5 for mechanically inserting and ejecting is a main power source for supplying electric power.

Next, the operation of the above conventional device will be described. First, when power is supplied from the main power supply 5 and the cartridge 1 is inserted from the cartridge insertion opening 2,
The loading mechanism unit 4 loads the cartridge 1. When the cartridge 1 is in the optical disk device, the loading mechanism unit 4 is driven by the cartridge eject button 3 or a command from the host computer to drive the cartridge 1 from the optical disk device.
Is discharged.

On the other hand, when power is not supplied from the main power supply 5, that is, when the main power supply 5 is off, the cartridge 1 still inserted in the optical disk device cannot be ejected.

[0005]

Since the conventional optical disk device is constructed as described above, if the main power supply 5 is turned off while the cartridge 1 is still inserted, the cartridge 1 is confined in the optical disk device. It is left as it is. Therefore, in order to eject the cartridge 1, it is necessary to turn on the main power supply 5 again.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an optical disk device capable of ejecting a cartridge even when the main power supply is OFF.

[0007]

The optical disk device according to the present invention comprises a standby power supply capable of driving the loading mechanism even when the power supply from the main power supply is cut off.

In addition, when the power supply from the main power supply is cut off, a standby power supply is provided which can drive the loading mechanism and access data.

[0009]

In the optical disk device of the present invention, the main power supply is turned off.
In this case, when ejecting the cartridge that has been inserted into the optical disk device and trapped, the cartridge is ejected by receiving power from the standby power supply.

Further, it is possible to access the data and record / reproduce.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, 1 is a cartridge containing an optical disk, 2 is a cartridge insertion port, 3 is a cartridge eject button for sending a signal for ejecting the retracted cartridge 1, and 4 is a loading mechanism for mechanically inserting and ejecting the cartridge. Units 5 are main power supplies for supplying electric power, and are the same as the components of the conventional device (shown in FIG. 2). In the case of the present embodiment, the backup power source 6 composed of a dry battery for driving the loading mechanism section 4 in the optical disk device.
Are arranged.

Next, the operation of the above embodiment will be described. When power is being supplied from the main power supply 5, the loading mechanism section 4 is driven by the power of the main power supply 5 to load or unload the cartridge 1 from the cartridge insertion port 2 as in the conventional case. When power is not supplied from the main power supply 5, when the cartridge eject button 3 is pressed, power is supplied from the standby power supply 6 and the cartridge 1 enclosed in the optical disk device is ejected.

In the above embodiment, the dry battery was used as the backup power source, but it can be used as a backup power source by replacing it with a capacitor and applying a voltage to the capacitor to store an electric charge when the main power source is ON. Also, a rechargeable battery can be used as a standby power source.

In the above embodiment, the case where the cartridge confined in the optical disk is ejected has been described. However, depending on the capacity of the standby power source, not only the loading operation of the cartridge but also all the optical disks such as access, data writing, and reproduction are performed. It can be used for device functions.

[0015]

As described above, according to the present invention, since the power is supplied from the standby power source even when the main power source is OFF, the cartridge enclosed in the optical disk device can be discharged, and the main power source is again supplied. There is no need to turn on. Also, data access, recording, and reproduction are possible.
