Description

The present invention relates to a storage device that stores a plurality of recording media.
Select the specified recording medium, transfer it to the recording / playback device,
The present invention relates to an autochanger device for recording an information signal on a selected recording medium or reproducing an information signal recorded on a recording medium.

2. Description of the Related Art Conventionally, an autochanger device includes a shelf for storing a recording medium, a transfer mechanism for transferring the recording medium from the shelf to the recording / reproducing device, the recording / reproducing device, and a control device and a power source for controlling the entire autochanger.

In the conventional autochanger device, the shelf, the transfer mechanism, the recording / reproducing device, the control device and the power source are all housed in the same housing. (For example, U.S. Pat. No. 4,271,489) Since a control device and a power source generally radiate heat, it is necessary to radiate heat from a housing in order to protect a recording medium vulnerable to heat. Therefore, a fan is provided to efficiently dissipate heat from the housing.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, since a recording medium (optical disk, magnetic tape, etc.) is vulnerable to adhesion of dust, the recording medium of the recording medium due to the dust sucked in from the gap of the casing at the same time by the action of the exhaust fan in the casing. There was a problem in recording and reproducing. Also, when a fan with a filter is installed to introduce outside air into the housing, the power supply unit and control unit inside the housing must be cooled at the same time, which requires a very large fan, which is expensive and uneconomical. .

The present invention is intended to solve the above problems, and an object of the present invention is to provide an autochanger device capable of effectively radiating heat and reducing the atmosphere of a recording medium with less dust.

Means for Solving the Problems According to the present invention, a shelf for storing a recording medium, a recording / reproducing device, and a transfer mechanism are housed in a first housing, and outside air is introduced into the first housing by a suction fan through a filter. The power supply device and the control device, which generate a lot of heat, are housed in the second housing, the first housing and the second housing are connected to each other through the air holes, and the first fan is connected to the first housing by the suction fan. The introduced air is discharged to the outside air through the discharge fan provided in the second housing.

With the above configuration, the atmosphere in which the recording medium is stored can be protected from dust, and the power supply device and the control device that require heat radiation can be effectively radiated.

Embodiment FIG. 1 is a block diagram of an automatic changer device for an optical disk according to an embodiment of the present invention.

1 is a first housing, 2 is a second housing, 3 is a suction fan with a filter, 4 is a recording medium storage shelf, 5 is a transfer mechanism, 6 is a recording / reproducing device, and 7 is a second housing. A power supply device is provided, 8 is also a control device, 9 is an exhaust fan, and 10 is air light provided between the first casing and the second casing.

Next, the operation will be described. The optical disk cartridges stored in the recording medium storage rack 4 are loaded into the recording / reproducing apparatus 6 or stored in the shelf 4 from the recording / reproducing apparatus by the transfer mechanism 5. The recording / reproducing apparatus 6 receives power from the power source 7, and the controller 8 controls the transfer mechanism 5 and the recording / reproducing apparatus 6. The outside air from which dust has been removed by the fan with filter 3 is introduced into the first casing 1 to protect the optical disc housed in the optical disc cartridge from dust. The air light 10 is set so that the air pressure inside the first casing 1 is higher than the outside air, and the air is supplied to the second casing 2 to supply the power 7 and the controller 8 Dissipate heat. A method of setting in this way is possible by appropriately setting the air intake amount and the air discharge amount. At the same time, the discharge fan 9 discharges the air in the second casing 2 to enhance the heat radiation effect.

FIG. 2 is a graph showing the effect of the present invention. In FIG. 2, the horizontal axis represents the passage of time and the vertical axis represents the reproduction amplitude of the optical disc. The reproduction amplitude generally represents the quality of the reproduction signal of the optical disc. The line segment indicated by A is the reproduction amplitude of the recording / reproducing apparatus incorporated in the autochanger of the present invention, and the line segment indicated by B is the reproduction amplitude of the recording / reproducing apparatus not incorporated in the autochanger. It was exposed to a very dusty atmosphere.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to realize an autochanger device for an optical disc or the like which is extremely resistant to dust and has a large heat dissipation effect.
