For example, Patent Document 1 proposes a computer system that has a structure that can be attached to and detached from a computer main body, and has an expansion unit that is connected to the computer main body to realize an extended function. The computer system is provided in the computer main body, a first heat radiating member for radiating heat inside the computer main body, and a second heat radiating member provided in the expansion unit for radiating heat inside the computer main body. Member. In the computer system, when the expansion unit is mounted on the computer body, the first heat radiating member and the second heat radiating member are connected by the connecting means for connecting the first heat radiating member and the second heat radiating member. Power mode setting means for setting the operation mode of the computer main body to the normal power mode or the full power mode when the member is connected, and setting the low power mode when the computer main body operates independently without using the expansion unit It comprises.

 まず、情報処理ユニット2が起動されると(ステップS1)、情報処理部22は、クロック周波数として予め設定されている第1のクロック周波数で動作する(ステップS2)。 First, when the information processing unit 2 is activated (step S1), the information processing unit 22 operates at a first clock frequency preset as a clock frequency (step S2).
 次いで、クロック周波数制御部23は、情報処理ユニット2に外付け放熱フィン4が装着されているか否かを判別する(ステップS3)。クロック周波数制御部23は、ショートピン41による短絡が発生しているときは、情報処理ユニット2に外付け放熱フィン4が装着されていると判別し、ショートピン41による短絡が発生していないときは、情報処理ユニット2に外付け放熱フィン4が装着されていないと判別する。たとえば、クロック周波数制御部23は、ショートピン41により短絡された経路の電流を測定することにより、ショートピン41による短絡の発生を判別することができる。 Next, the clock frequency control unit 23 determines whether or not the external heat radiation fin 4 is attached to the information processing unit 2 (step S3). The clock frequency control unit 23 determines that the external heat radiation fin 4 is attached to the information processing unit 2 when a short circuit is caused by the short pin 41, and the short circuit is not caused by the short pin 41. Determines that the external heat radiation fin 4 is not attached to the information processing unit 2.

The second clock frequency is higher than the first clock frequency.
 次いで、情報処理部22は、ステップS4で設定された第2のクロック周波数で動作する(ステップS5)。 Next, the information processing section 22 operates at the second clock frequency set in step S4 (step S5).
 ステップS3での判別の結果、情報処理ユニット2に外付け放熱フィン4が装着されていないときは(ステップS3でNo)、クロック周波数制御部23は、情報処理ユニット2に外付け放熱フィン5が装着されているか否かを判別する(ステップS6)。クロック周波数制御部23は、ショートピン51による短絡が発生しているときは、情報処理ユニット2に外付け放熱フィン5が装着されていると判別し、ショートピン51による短絡が発生していないときは、情報処理ユニット2に外付け放熱フィン5が装着されていないと判別する。たとえば、クロック周波数制御部23は、ショートピン51により短絡された経路の電流を測定することにより、ショートピン51による短絡の発生を判別することができる。 As a result of the determination in step S3, when the external heat radiation fin 4 is not attached to the information processing unit 2 (No in step S3), the clock frequency control unit 23 has the external heat radiation fin 5 attached to the information processing unit 2. It is determined whether or not it is attached (step S6). The clock frequency control unit 23 determines that the external radiating fin 5 is attached to the information processing unit 2 when a short circuit due to the short pin 51 occurs, and the short circuit due to the short pin 51 does not occur. Determines that the external heat radiation fin 5 is not attached to the information processing unit 2. For example, the clock frequency control unit 23 can determine the occurrence of a short circuit by the short pin 51 by measuring the current of the path short-circuited by the short pin 51.
 ステップS6での判別の結果、情報処理ユニット2に外付け放熱フィン5が装着されているときは(ステップS6でYes)、クロック周波数制御部23は、情報処理部22のCPUのクロック周波数を、第3のクロック周波数に設定する(ステップS7)。第3のクロック周波数は、第1のクロック周波数よりも高く、第2のクロック周波数よりも高い周波数である。 As a result of the determination in step S6, when the external heat radiation fin 5 is attached to the information processing unit 2 (Yes in step S6), the clock frequency control unit 23 sets the CPU clock frequency of the information processing unit 22 to The third clock frequency is set (step S7). The third clock frequency is higher than the first clock frequency and higher than the second clock frequency.
 次いで、情報処理部22は、ステップS7で設定された第3のクロック周波数で動作する(ステップS8)。 Next, the information processing section 22 operates at the third clock frequency set in step S7 (step S8).
 ステップS6での判別の結果、情報処理ユニット2に外付け放熱フィン5が装着されていないときは(ステップS6でNo)、ステップS3の処理に戻る。 As a result of the determination in step S6, when the external heat radiation fin 5 is not attached to the information processing unit 2 (No in step S6), the process returns to step S3.
 図3に示すCPU高速化処理によれば、クロック周波数制御部23は、情報処理ユニット2に外付け放熱フィン4,5のうちのいずれの外付け放熱フィン4,5が装着されているかを、外付け放熱フィン4,5が備えるショートピン41,51のうちのいずれのショートピン41,51による短絡が発生しているかで判別し、CPUのクロック周波数を情報処理ユニット2に装着されているいずれの外付け放熱フィン4,5に見合ったものに設定可能である。換言すれば、クロック周波数制御部23は、装着されている外付け放熱フィン4,5の冷却能力を、外付け放熱フィン4,5の接続状況に基づいて判別し、CPUのクロック周波数を冷却能力に応じて変化させることが可能である。クロック周波数制御部23は、装着されている外付け放熱フィン4,5の冷却能力を、外付け放熱フィン4,5が備えるショートピン41,51の位置および配列で判別することが可能であり、CPUのクロック周波数を冷却能力に応じて変化させることが可能である。 According to the CPU acceleration processing shown in FIG. 3, the clock frequency control unit 23 determines which of the external heat radiation fins 4, 5 is attached to the information processing unit 2. It is determined which one of the short pins 41, 51 provided in the external heat radiation fins 4, 5 is short-circuited, and the CPU clock frequency is attached to the information processing unit 2. The external heat radiation fins 4 and 5 can be set appropriately. In other words, the clock frequency control unit 23 determines the cooling capacity of the attached external radiating fins 4 and 5 based on the connection status of the external radiating fins 4 and 5 and determines the CPU clock frequency as the cooling capacity. It is possible to change according to. The clock frequency control unit 23 can determine the cooling capacity of the attached external radiating fins 4 and 5 by the position and arrangement of the short pins 41 and 51 provided in the external radiating fins 4 and 5. It is possible to change the clock frequency of the CPU according to the cooling capacity.
 本実施の形態では、外付け放熱フィン4,5のいずれかが情報処理ユニット2に装着された場合には、CPUのクロック周波数が2つの周波数のいずれかに設定されたが、3つ以上の外付け放熱フィンのうちのいずれかが情報処理ユニット2に装着された場合には、CPUのクロック周波数が3つ以上の周波数のうちのいずれかに設定されるようにしてもよい。ソケット21に形成されているピン穴の個数、および外付け放熱フィンが有するショートピンの間隔を調整することにより、外付け放熱フィンが有するショートピンの位置および配列を異ならせることができ、クロック周波数制御部23は、3つ以上の外付け放熱フィンのうちのいずれかが情報処理ユニット2に装着されたことを判別することができる。 In the present embodiment, when any of the external radiating fins 4 and 5 is attached to the information processing unit 2, the CPU clock frequency is set to one of the two frequencies. When any of the external radiating fins is attached to the information processing unit 2, the CPU clock frequency may be set to any one of three or more frequencies. By adjusting the number of pin holes formed in the socket 21 and the distance between the short pins of the external radiating fins, the position and arrangement of the short pins of the external radiating fins can be varied, and the clock frequency The control unit 23 can determine that any one of the three or more external radiating fins is attached to the information processing unit 2.
 本実施の形態では、ピン41a,41bの間隔の大きさと、ピン51a,51bの間隔の大きさとは、外付け放熱フィン4,5の冷却能力に応じた大きさとしてもよい。本実施の形態では、外付け放熱フィン4の冷却能力よりも外付け放熱フィン5の冷却能力の方が高いため、ピン51a,51bの間隔の大きさは、ピン41a,41bの間隔の大きさよりも大きい。一般に、ピンの間隔が大きい場合、ピンの間隔が小さい場合と比較して、情報処理ユニットと外付け放熱フィンとの接続強度を高めることができる。このため、情報処理ユニット2と外付け放熱フィン4との接続強度よりも情報処理ユニット2と外付け放熱フィン5との接続強度を高くすることができる。また、ショートピン41のピン41a,41bの間隔の大きさと、ショートピン51のピン51a,51bの間隔の大きさとを、外付け放熱フィン4,5の冷却能力に応じた大きさとする場合、たとえばショートピン41が差し込まれるはずのピン穴21a,21b以外のピン穴21b、21cにショートピン41が差し込まれたときでも、クロック周波数制御部23は外付け放熱フィン4の冷却能力をショートピン41のピン41a,41bの間隔の大きさで判別することも可能となる。 In the present embodiment, the distance between the pins 41a and 41b and the distance between the pins 51a and 51b may be determined according to the cooling capacity of the external heat radiation fins 4 and 5. In the present embodiment, the cooling capacity of the external heat radiation fin 5 is higher than the cooling capacity of the external heat radiation fin 4, so that the distance between the pins 51a and 51b is larger than the distance between the pins 41a and 41b. Is also big. Generally, when the pin interval is large, the connection strength between the information processing unit and the external radiating fin can be increased as compared with the case where the pin interval is small. For this reason, the connection strength between the information processing unit 2 and the external heat radiation fin 5 can be made higher than the connection strength between the information processing unit 2 and the external heat radiation fin 4. Further, when the distance between the pins 41a and 41b of the short pin 41 and the distance between the pins 51a and 51b of the short pin 51 are set according to the cooling capacity of the external radiation fins 4 and 5, for example, Even when the short pin 41 is inserted into the pin holes 21b and 21c other than the pin holes 21a and 21b into which the short pin 41 is to be inserted, the clock frequency control unit 23 sets the cooling capacity of the external radiating fin 4 to the short pin 41. It is also possible to discriminate by the size of the interval between the pins 41a and 41b.
 本実施の形態では、クロック周波数制御部23は、装着されている外付け放熱フィン4,5の冷却能力を、外付け放熱フィン4,5が備えるショートピン41,51の位置および配列で判別していたが、外付け放熱フィン4,5が備えるピンの本数、ピンの太さ、またはピンの長さで、装着されている外付け放熱フィン4,5の冷却能力を判別するようにしてもよい。この場合、ソケット21には、たとえば、ピンの本数分のピン穴、ピンの太さに対応したピン穴、またはピンの長さに対応したピン穴が形成される。 In the present embodiment, the clock frequency control unit 23 determines the cooling capacity of the attached external radiating fins 4 and 5 by the position and arrangement of the short pins 41 and 51 provided in the external radiating fins 4 and 5. However, the cooling capacity of the attached external radiation fins 4 and 5 may be determined by the number of pins, the thickness of the pins, or the length of the pins provided in the external radiation fins 4 and 5. Good. In this case, for example, a pin hole corresponding to the number of pins, a pin hole corresponding to the thickness of the pin, or a pin hole corresponding to the length of the pin is formed in the socket 21.
 本実施の形態では、情報処理ユニット2と、外付け放熱フィン4,5との電気的接続および固定をショートピン41,51で行っているが、電気的接続および固定の両機能を有する部材、たとえば情報処理ユニット2を挟み込むような形状の金具で行ってもよい。 In the present embodiment, electrical connection and fixing between the information processing unit 2 and the external radiating fins 4 and 5 are performed by the short pins 41 and 51, but members having both functions of electrical connection and fixing, For example, a metal fitting having a shape that sandwiches the information processing unit 2 may be used.

 本実施の形態では、外付け冷却ファン6,7のいずれかが情報処理ユニット2に装着された場合には、CPUのクロック周波数が2つの周波数のいずれかに設定されたが、3つ以上の外付け冷却ファンのうちのいずれかが情報処理ユニット2に装着された場合には、CPUのクロック周波数が3つ以上の周波数のうちのいずれかに設定されるようにしてもよい。ソケット21に形成されているピン穴の個数、および外付け冷却ファンが有するショートピンの間隔を調整することにより、外付け冷却ファンが有するショートピンの位置および配列を異ならせることができ、クロック周波数制御部23は、3つ以上の外付け冷却ファンのうちのいずれかが情報処理ユニット2に装着されたことを判別することができる。 In the present embodiment, when any one of the external cooling fans 6 and 7 is attached to the information processing unit 2, the CPU clock frequency is set to one of the two frequencies.
