Abstract

PURPOSE:To effectively radiate heat and to reduce dust in the atmosphere of a recording medium by introducing fresh air from which the dust is eliminated to a first enclosure, protecting an optical disk from the dust, supplying the air through an air hole to a second enclosure, and radiating the heat of a power source and a controller. CONSTITUTION:A shelf 4 to house a recording medium, a recording/reproducing device 6, a shift mechanism 5 are housed to a first enclosure 1, and the fresh air is introduced through a filter to the first enclosure 1 by a suction fan 3. Further, a power source device 7 and a controller 8 which generate much heat are housed in a second enclosure 2, the first enclosure 1 is linked through an air hole 10 to the second enclosure 2, and the air introduced to the first enclosure 1 by the suction fan 3 is discharged through a discharging fan 9 provided at the second enclosure 2 to the outside. Thus, the atmosphere housing the recording medium can be protected from the dust, and the power source device 7 and the controller to require radiation can effectively radiates heat.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a storage device storing a plurality of recording media.
Select the specified recording medium, transfer it to the recording and reproducing device,
This relates to an autochanger device that records information signals on a selected recording medium or reproduces information signals recorded on a recording medium. Conventional technology Conventionally, an autochanger device consists of a transfer mechanism that transfers the recording medium from a shelf that stores the recording medium to a recording/playback device, a recording/playback device, a controller that controls the entire autochange operation, and a power source. ing. In conventional autochanger devices, the transfer mechanism, recording/reproducing device, control device, and power source are all housed in the same housing. (For example, U.S. Pat. No. 4.27
1,489) Since control devices and power sources generally radiate heat, in order to protect recording media that are sensitive to heat,
It was necessary to dissipate heat from the casing. Therefore, a fan was installed to efficiently dissipate heat from the housing. Problem to be Solved by the Invention However, since recording media (optical disks, magnetic tapes, etc.) are susceptible to dust adhesion, the dust that is sucked into the housing through the gaps in the housing by the action of the exhaust fan causes the recording medium to become unrecorded. This sometimes caused problems with playback. Furthermore, even if a fan with a filter is installed to introduce outside air into the housing, the power supply and control equipment inside the housing must be cooled at the same time, which requires a very large fan, which is expensive and uneconomical. ．． The present invention aims to solve the above problems, and aims to provide an autochanger device that can effectively dissipate heat and make the atmosphere of a recording medium less dusty.

Means for Solving the Problems In the present invention, a recording/reproducing device for storing a recording medium and a transfer mechanism are housed in a first casing, and outside air is introduced into the first casing by an intake fan via a filter. The 7Fi source device and control device, which generate a lot of heat, are housed in the second housing, and the first housing and the second housing are connected through the air hole, and the air introduced into the first housing by the intake fan is stored in the second housing. The air is discharged to the outside air through an exhaust fan installed in the second housing. Function: By configuring as described above, the atmosphere in which the recording medium is stored can be protected from dust, and the heat can be effectively radiated from the power supply device and control device that require heat radiation. Embodiment FIG. 1 is a block diagram of an autochanger device for optical discs which is an embodiment of the present invention.

■ is the first housing; 2 is the second housing; 3 is the suction fan with a filter; 4 is the recording medium housing; 5 is the transfer mechanism; 6 is the recording/playback device; 7 is the power supply installed in the second housing. 8 is also a control device, 9 is an exhaust fan, lO
is an air hole provided between the first housing and the second housing. Next, we will explain the operation. The optical disk cartridge stored in the recording medium storage shelf 4 is loaded into the recording/reproducing device 6 by the transfer mechanism 5, or is stored in the shelf 4 from the recording/reproducing device. The recording and reproducing device 6 receives power from the power supply device 7, and the transfer mechanism 5 and the recording and reproducing device 6 are controlled by the control device 8. The outside air from which dust has been removed by the fan with filter 3 is introduced into the first housing 1 to protect the optical disc housed in the optical disc cartridge from dust.

The air holes of the IO are set so that the air pressure inside the first housing of 1 is higher than the outside air, and
Air is supplied to the housing of , and heat is radiated from the power supply of 7 and the control device of 8. This method can be achieved by appropriately setting the air intake and air output.
At the same time, the exhaust fan 9 exhausts the air from the second housing 2, increasing the heat dissipation effect. FIG. 2 is a graph showing the effects of the present invention. In Figure 2, the horizontal axis shows the passage of time, and the vertical axis shows the reproduction amplitude of the optical disc. Reproduction amplitude generally represents the quality of the reproduction signal of an optical disc. The line segment marked A is the playback amplitude of the recording/playback device incorporated into the autochanger of the present invention, and the line segment marked B is the playback amplitude of the record/playback device not built into the autochanger. Therefore, it was exposed to a very dusty atmosphere.

Effects of the Invention As described above, according to the present invention, an autochanger device for optical discs, etc., which is extremely dust resistant and has a large heat dissipation effect has been realized.
