In the embodiment of the present invention, such a disk medium reading apparatus is used as a home game machine 20 having a CD as shown in FIG. The consumer game machine 20 reads information recorded on a removable CD ROM 11 by an optical pickup 12p, converts the information into video and audio via a consumer television, and allows an operator to play a game. The configuration is as shown in FIG.

It is composed of a cover 23, a power supply and signal transmission cord (only part of which is shown) 24 connected to the lower case 21, and the like.

In the lower case 21, as shown in FIG.
On the bottom surface, a first control board 31, a power supply unit 33, and an external interface unit 34 for controlling various functions of the game machine are provided. The first control board 31 includes:
It controls the rotation of the CDROM 11 and controls the optical pickup 1
A second control board 32 for controlling 2p driving and reading is mounted, and on the second control board 32, a rotary drive section of the CDROM 11 and a moving section of the optical pickup with a duct 13 described later interposed therebetween. Is fixed.

The CDROM drive / read section 12 has a CDROM rotation drive section 12d on one side, and an optical pickup moving section (not shown) formed from one side in the longitudinal direction, and has a CDROM 11 mounted thereon. Sometimes C
The optical pickup 12p can move in the radial direction of the DROM 11. An optical pickup moving space is formed around the optical pickup moving section inside the CDROM driving and reading section 12 so as not to hinder the movement of the optical pickup 12p, and a slit is formed on the upper surface of the CDROM driving and reading section 12 in the longitudinal direction. 12s are formed,
The optical pickup 12p is connected to the CDR via the slit 12s.
The information recorded on the OM 11 is read. This optical pickup moving space and the slit 12s
Means to form a part of an air guide path to be described later. When the CDROM 11 is mounted, the slit forming surface of the CDROM drive reading unit 12
, For example, at a distance of 0.5 mm to 1 mm or the like.

As shown in FIGS. 3 and 4, a duct 13 for introducing cooling air extends from the lower portion of the CDROM drive reading section 12 toward the case side wall. The one end opening 13a of the duct 13 is arranged so as to coincide with a plurality of cooling air introduction holes 22b formed in the side wall of the upper case 22 shown in FIG.
The other end opening 13b of the CDROM drive reading unit 1
2 optical pickup moving space.

As shown in FIG. 3, a heat-generating electronic component such as a thyristor is mounted on a power supply unit 33 disposed in a part of the lower case 21.
5 is connected to one end. The other end of the heat pipe 35 is fixed at a predetermined position in the duct 13 into which the cooling air is introduced. The heat pipe 3 used here
5 is a small heat transfer member that transfers heat from one end to the other end by repeating evaporation and condensation of the working fluid sealed inside.

The cover 23 shown in FIG. 2 attached to the upper case 22 is used to protect the rotating CDROM 11 by mounting the CDROM 11 after the CDROM 11 is mounted thereon. A plurality of air outlet holes 23b for leading air to the outside are formed. Next, the operation of the electronic component cooling structure of the disk medium reader according to the above-described embodiment will be described.

First, the CDROM 11 is fitted into the CDROM drive reading section 12 of the consumer game machine 20 (shown in FIG. 1 with the upper case 22 and the cover 23 omitted). Subsequently, the cover 23 is closed and the operation of the consumer game machine 20 is started. Thereby, the CDROM drive / read unit 12 rotates the CDROM 11 and
Move the optical pickup 12p to a predetermined position, and
The reading of the information recorded in M11 is started.

When the CDROM 11 rotates at a predetermined angular velocity, the gap (about 0.5 mm to 1 mm) between the lower surface of the CDROM 11 and the CDROM drive / read section 12 and the CDROM 1
The air interposed between the upper surface of the first case 22 and the upper case 22 is C
It is sent out in the circumferential direction of the CDROM 11 by the rotational force of the DROM 11. The air existing in this region is supplied to the air outlet holes 23 b of the cover 23 and the cover 23.
Game machine 20 through the gap between the
Is derived outside. Similarly, the air interposed between the upper surface of the CDROM 11 and the cover 23 is also led out of the consumer game machine 20 through the air outlet hole 23b of the cover 23 and the gap between the cover 23 and the upper case 22. At the same time, a negative pressure is generated in a region sandwiched between the CDROM drive / reader 12 and the lower surface of the CDROM, and the air existing in the duct 13 passes through the space in the CDROM drive / reader 12 due to the negative pressure. CDRO from 12s
M is guided to the area of the lower surface. At the same time, air outside the home game machine is introduced into the duct 13 via the air introduction hole 22b of the upper case 22.

Specifically, a wind guide path is formed as schematically shown in FIG. That is, CDRO
The rotation of M11 allows air outside the home game machine to flow through the air inlet 22b of the upper case 22 and the duct 1 without having a forced cooling structure such as a cooling fan.
3. Space in CDROM drive reading unit 12, CDRO

Cover 2 via the inside of the home game machine in the order of
The home game machine 20 is again returned from the air outlet holes 23b on the three rims.
Is derived outside. Also, the CDROM 11 and the cover 23
5 is also led out of the consumer game machine 20 as shown by the arrow in FIG.

During the rotation of the CDROM 11, the cooling air guide path is always formed as described above.
The optical pickup 12p located in the vicinity of
During one rotation, cooling can be always performed. In addition, since the flow of the cooling air is narrowed at the slit 12s, the air flow speed increases near the slit 12s, and the cooling efficiency of the optical pickup 12p can be further improved.

On the other hand, heat generated by electronic components such as a thyristor mounted on the power supply unit 33 is radiated into the duct 13 via the heat pipe 35. Therefore, it is not necessary to cool the optical pickup and the heat-generating electronic components mounted on the power supply unit and the like by the cooling fan as in the conventional home game machine. Even if a cooling fan is provided, unlike conventional home game machines, it is sufficient to provide an auxiliary small fan, so it is possible to eliminate or significantly reduce the noise generated by the cooling fan. Becomes

Further, since the cooling air guide path is formed in a limited manner, unnecessary cooling such as that required in the conventional forced cooling by a cooling fan of a home-use game machine is not performed. There is no unnecessary dispersion of dust accumulated inside the case. Therefore, it is possible to prevent such dust from adhering to the optical pickup and erroneously detecting data in the CDROM.

Further, since the air flow is generated by utilizing the negative pressure generated when the CDROM 11 rotates, the CDROM 11
The optical pickup 12p is always cooled at the time of reading 11, so that the cooling of the optical pickup at the time of reading the CDROM is not impossible due to the failure of the cooling fan as in the conventional home-use game machine.
Note that, unlike the above-described embodiment, any electronic component other than the optical pickup may be arranged on the air guide path of the cooling air introduced from the guide portion, and thereby, the heat generated by the electronic component is reliably radiated. be able to.

If the air passage for cooling air is properly formed, it is not always necessary to provide an air introduction hole in the upper case, and similarly, it is not necessary to provide an air outlet hole in the cover. Furthermore, if the heat-generating electronic components are sufficiently spaced from the optical pickup, it is not always necessary to dissipate heat using a heat pipe, and natural cooling or using an auxiliary cooling fan that is smaller than the conventional one is used. It may be cooled.

Next, another embodiment of the electronic component cooling structure of the disk medium reader according to the present invention will be described. Note that the same components as those in the above-described embodiment are denoted by the corresponding reference numerals in FIG. 6, and detailed description thereof will be omitted. A consumer game machine 50 according to another embodiment of the present invention includes a CDROM drive reading section 42, a printed circuit board 61, a duct and a power supply in a housing composed of a lower case 51, an upper case 52, and a cover 53. A home game machine in which a unit (not shown) and the like are built in the same configuration as in the above-described embodiment.

According to another embodiment of the present invention, the heat generated by the CPU 64 is reduced by the first heat pipe 65, the hinge member 67, and the second heat pipe 6.
The heat is transferred to the cover 53 via 6. Since at least the portion of the cover 53 to which the second heat pipe 66 is connected is made of a material having good thermal conductivity such as an aluminum heat radiating portion or a magnesium alloy, the amount of transferred heat is reduced by the heat radiating portion of the cover 53. The heat spreads over the entire surface and is naturally radiated from the upper surface of the cover 53, and is also transferred to the air passing between the cover 53 and the CDROM as shown in FIG. The cover 53 is a part having a very high heat radiation effect in the housing because the cover 53 is always in contact with the air flow inside the housing due to the rotation of the CDROM and also in contact with the air outside the housing. Therefore, in another embodiment of the present invention, the heat generated by the electronic components arranged other than the cooling air guide path can be more efficiently radiated.

It is not always necessary to use two heat pipes via a hinge member as in the above-described another embodiment, and any one of the heat pipes may be used in accordance with the component layout in the disk medium reader. It may be connected to the heat-generating electronic component or the heat radiating portion of the cover directly from the hinge member. Further, a metal plate such as aluminum as an electromagnetic shielding plate may be provided on the inner surface side of the cover 53, and this metal plate may also serve as a heat radiating plate.

In the two embodiments described above,
The heat-generating electronic components are not limited to thyristors and CPUs, but needless to say include ICs, transistors, transformers, regulators, electrolytic capacitors, and the like. Further, in the above-described embodiment of the present invention, the case where the electronic component cooling structure of the disk medium reading device is applied to a consumer game machine has been described. However, the applicable range of the electronic component cooling structure of the disk medium reading device according to the present invention is described. Is not limited to this, but includes CDROs such as laser disks, DVDs, audio CDs, and CDROM drive mechanisms for personal computers.
The present invention can be applied to a disk medium reading device that reads M by an optical pickup. Further, the present invention can be applied to a disk type magnetic recording medium such as a floppy disk and a disk medium reading apparatus including the reading apparatus other than the disk medium reading apparatus for optically reading the information of the disk medium.
