On the other hand, as the storage medium, there are various media such as a floppy disk and an IC memory in addition to the hard disk, and power is also supplied to the I / O interface and the like.

However, although a large amount of power is consumed to access a hard disk, a floppy disk consumes less power than that and an IC memory can be accessed with less power. Since it was uniformly inaccessible when the capacity became a certain value or less, the access operation was prohibited in the case of an IC memory even if it was originally possible to read or store data, resulting in a wasteful operation. It was dead.

Power is selectively supplied to the mounting units 10a, 10b, 10c and 10d to which the I / O interface 11d such as an AN card is mounted.

The battery remaining capacity detection unit 2 calculates the remaining capacity of the battery 1 based on the voltage or current from the battery 1. The data storage unit 3 stores write / read data to / from the medium, and thus is usually configured by a memory.
The data capacity / access time recognition unit 4 includes a data storage unit 3

The operation input recognition unit 8 inputs an instruction for a power saving mode, a data read / write operation, or the like.

The power supply state setting unit 7 receives information from the remaining battery capacity detection unit 2, the data capacity / access time recognition unit 4, the medium type recognition unit 6 and the operation input recognition unit 8 and supplies power based on these information. The switching units 9a to 9d are controlled to control the power feeding operation to the media 11a to 11d via the mounting units 10a to 10d. In FIG. 1, thick lines indicate power supply lines, thin lines indicate detection and control lines, and dotted lines indicate data lines.

Various embodiments of the present invention will be sequentially described below. First, a description will be given of an embodiment in which a plurality of types of media are mounted in the mounting units 10a to 10d as the media 11a to 11d and the power saving operation is executed when the remaining battery capacity is reduced, with reference to the flowchart of FIG. To do. In the following flowchart, a block in which two sides of the processing block are marked with thick lines is a subroutine.

When the processing is started and the power saving mode is input and stored by the operation input from the operation input recognition unit 8 (step S1), power supply to the motor of the HDD is restricted to save power (step S1). After S2), power is supplied only when an access instruction is issued. Next, HDD and F
The power supply to the DD is cut off to disable access to the medium such as HDD and FDD thereafter (step S3). continue,
The power supply to the I / O interface, which consumes more power than the memory system but consumes less power than the HDD, is cut off (step S4), and the power supply to the memory with the memory holding function that consumes the least power is cut off. (Step S5) Finally, the system power supply is cut off (Step S7). If the power saving mode is not input or set in step S1, the system power is cut off in step S1.
The process shifts to 7.

In short, the processing shown in FIG. 2 selects and controls the power supply interruption target for power saving in the order of the components (driving motor, disk, I / O interface, memory) having the largest power consumption (power saving). The transition to the deep step of the mode).

In each of the steps S2 to S5, when the problem of the remaining battery capacity is avoided such as when the external AC power source is connected or the battery itself is replaced, the energization limitation and the power supply interruption are canceled. (Step S6),
The process returns to step S1.

As shown in the flow chart of FIG. 3, the processing of step S1 of FIG. 2 is performed after the user inputs a power saving mode instruction with the switch of the operation input recognition unit 8 (step S11). Is instructed (step S12), the power saving mode is input by the next operation input only in the power saving mode, and the storage routine is ended (step S14). If not, the system of step S6 is executed. The process proceeds to the power shutoff routine (step S13).

Next, the HD in step S3 of FIG.
A procedure for interrupting power supply to D and FDD will be described with reference to the flowchart of FIG.

When the routine is started, it is determined whether the HDD or FDD is connected to the I / O interface or the memory with a storage holding function (step S21). This process is a process for determining whether or not the HDD or FDD having a mechanical mechanism is always mounted, and either the I / O interface having no mechanical mechanism or the memory with a memory holding function is connected. . If either of them is connected (Y), check the remaining capacity of the depleted battery and check if the battery voltage is HDD or FD.
It is determined whether or not the power supply cutoff setting voltage V1 to D has fallen (step S22).

If it is determined in step S22 that the remaining capacity is sufficient and the battery voltage is higher than V1, the process returns to step S21 to wait for the remaining capacity to decrease, and if the battery voltage is lower than V1, the HDD , The power supply to the FDD is cut off (step S23), and it is determined whether the battery is replaced or the external power source is connected (step S24). If it is determined that the battery has been replaced or the external power supply has been connected, the process proceeds to the main routine start process in step S25, that is, the restriction in step S6 of FIG. 2 and the release of power supply interruption (step S26). If it is determined that the battery has not been replaced or the external power supply has not been connected, the power supply cutoff routine for the HDD and FDD is terminated (step S26), and the power saving mode shifts to a deeper step.

The procedure for interrupting the power supply to the I / O interface in step S4 of FIG. 2 will be described with reference to the flowchart of FIG.

In this processing, it is determined whether or not both the I / O interface and the memory with a memory holding function are connected, that is, whether or not the hardware satisfies the specifications (step S31). If both are not connected, the power supply interruption routine of the I / O interface is temporarily terminated (step S36), and the process proceeds to step S5 of the main routine of FIG.

If it is determined in step S31 that the battery is connected, it is determined whether or not the battery voltage has dropped below the power supply cutoff setting voltage V2 to the I / O interface due to battery exhaustion (step S32). If not,
Return to the processing of step S31, and if it is below, I / O
The power supply to the interface is cut off (step S33).
Subsequently, it is determined whether the battery has been replaced or an external power source has been connected (step S34), and if it is determined that the battery has been replaced or connected, the process proceeds to step S6 in FIG. 2 (step S35). If not, the routine for stopping the power supply to the I / O interface is terminated (step S).
36).

Next, the power cutoff process to the memory with the memory holding function in step S5 of FIG. 2 will be described with reference to FIG.

First, it is judged whether or not the memory with the memory holding function is connected (step S41), and if not connected, the power supply interruption routine to the memory with the memory holding function is ended (step S46), and the connection is established. If so, it is determined whether or not the battery is exhausted and the battery voltage has dropped below the power supply cutoff setting voltage V3 for the memory with a memory holding function (step S42). If the battery voltage is not lower than V3, the process returns to step S41, and if it is lower than V3,
The power supply to the memory is cut off (step S43). After the power supply is cut off, it is determined whether or not the battery has been replaced or the external power source has been connected (step S44). If yes, the main routine of step S6 of FIG. 2 is reached (step S45). For example, the power supply interruption routine to the memory is terminated as described above (step S4).
6) Go to further power saving mode.

As shown in FIG. 7, the routine for canceling the restriction and power cutoff in step S6 of FIG. 2 releases all restrictions and power cutoff (step S51).
This is the process of ending the cancellation routine (step S52).

As shown in FIG. 8, the system power shutdown routine in step S7 of FIG. 2 determines whether the battery is exhausted and the battery voltage has dropped below the system power shutdown voltage V4 (step S61). The system power supply is cut off after the temperature falls below the threshold (step S62). You can continue to boot the system until the battery is completely exhausted, but if you do so, the system will end instable and the contents of the hard disk will be destroyed, or the system will start up unstable the next time you start up. In order to avoid this, the processing is performed as described above.

Next, FIG. 9 showing an embodiment for executing a power saving operation when a plurality of types of media are loaded in a single loading section
This will be described with reference to the flowchart of FIG.

In this embodiment, the power supply switching section 9b shown in FIG. 1 is used.
9d and the corresponding mounting portions 10b to 10d are absent, assuming that any one of the media 11a to 11d is mounted in the single mounting portion 10a, the components denoted by lowercase letters in FIG. Not included.

When the processing is started, the power saving mode is input by the operation input from the operation input recognition unit 8 as in FIG.
After the memory is stored (step S101), the motor of the HDD is continuously energized to save power (step S101).
102), the power supply to the HDD or FDD is cut off to disable access to the medium such as a hard disk or a floppy disk thereafter (steps S103 and S104). In step S102, since the HDD motor is constantly supplied with current and the HDD is constantly operating, current is not normally supplied to the motor, and current is supplied only during access to drive the HDD motor.

Subsequently, the power supply to the I / O interface is cut off (step S105), the power supply to the memory with the storage holding mechanism that consumes the least power is cut off (step S106), and the system power is finally supplied. Is cut off (step S108). If the power saving mode is not input and set in step S101, the process proceeds to a process of shutting off the system power (step S108).

In each of steps S102 to S106, when the problem of the remaining battery capacity is avoided as in the case where the external AC power source is connected or the battery itself is replaced, the energization limitation and the power supply interruption are canceled. Then (step S107), the process returns to step S101.

The HDD motor constant energization stop routine in step S102 of FIG. 9 will be described with reference to the flowchart of FIG.

When the routine is started, it is determined whether the HDD is connected (step S111).
If it is determined that the battery is connected, the battery is exhausted, the remaining capacity of the battery is confirmed by the battery voltage, and it is determined whether the battery voltage is lower than the HDD continuous energization stop voltage V5 (step S112). .

If it is determined in step S112 that the remaining capacity is sufficient and the battery voltage is higher than V5, the process returns to step S111, and if the battery voltage is lower than V5, the power is supplied only during access. The constant power supply to the motor is stopped (step S113), and it is determined whether the battery is replaced or the external power source is connected (step S114). If it is determined that the battery has been replaced or the external power supply has been connected, the process proceeds to the main routine start process in step S115, that is, the restriction and power cutoff cancellation in FIG. 9 (step S107). If it is determined that the battery has not been replaced or the external power supply has not been connected, the HDD motor constant power supply stop routine is terminated (step S116).

Next, H in step S103 of FIG.
A power supply cutoff routine for the DD motor will be described with reference to the flowchart of FIG.

When the routine is started, it is determined whether the HDD is connected (step S121).
Here, if it is determined that the battery is not connected, it is impossible to save power, and the process proceeds to step S126 to be described later. If it is determined that the battery is connected, the remaining capacity of the battery is confirmed, and the battery voltage is HDD. It is determined whether or not the constant energization stop voltage V6 has been dropped (step S122).

If it is determined in step S122 that the remaining capacity is sufficient and the battery voltage is higher than V6, the process returns to step S121 to wait for battery exhaustion, and if the battery voltage falls below V6, the HDD is activated. The power supply is cut off (step S123), and it is determined whether the battery is replaced or the external power supply is connected (step S124). If it is determined that the battery has been replaced or the external power supply has been connected, in step S125, the process proceeds to the main routine start process, that is, the restriction and power cutoff cancellation in FIG. 9 (step S107). If it is determined that the battery has not been replaced or the external power supply has not been connected, the routine for stopping energization of the HDD is terminated (step S12).
6).

Next, F in step S104 of FIG.
A power supply cutoff routine for the DD will be described with reference to the flowchart of FIG.

After starting the routine, it is first determined whether or not the FDD is connected (step S131).
If it is determined that the battery is not connected, the routine for cutting off the power supply to the FDD is ended (step S136). If it is determined that the battery is connected, the battery is exhausted, and the remaining capacity of the battery is determined by the battery voltage. It is checked and it is determined whether the battery voltage is lower than the FDD constant energization stop voltage V7 (step S1).
32).

If it is determined in step S132 that the remaining capacity is sufficient and the battery voltage is higher than V7, the process returns to step S131, and if the battery voltage is lower than V7, the power supply to the FDD is cut off ( In step S133), it is determined whether the battery has been replaced or the external power source has been connected (step S134). If it is determined that the battery has been replaced or the external power supply has been connected, step S1
In step 35, the process proceeds to the main routine start process, that is, the restriction and the cutoff of power supply in FIG. 9 (step S107). If it is determined that the battery has not been replaced or the external power supply has not been connected, the power supply cutoff routine to the FDD is terminated (step S136).

Next, the routine for interrupting power supply to the I / O interface in step S105 of FIG. 9 will be described with reference to the flowchart of FIG.

In step S141, it is determined whether or not the I / O interface is connected. If it is determined that the I / O interface is connected, the battery is exhausted and the battery voltage becomes I / O.
It is determined whether or not the power supply cutoff voltage V2 for the O interface has fallen (step S142). If it has not fallen, the process returns to step S141 to wait for battery exhaustion, and if it has fallen, the I / O interface The power supply is cut off (step S143). Subsequently, it is determined whether the battery is replaced or an external power source is connected (step S144), and if it is determined that the battery is replaced or connected, the process proceeds to step S107 in FIG. 9 (step S145), If not, the routine for interrupting power supply to the I / O interface ends (step S146).

Next, the routine for cutting off the power supply to the memory with the memory holding function in step S106 of FIG. 9 will be described with reference to the flowchart of FIG.

First, it is determined whether or not the memory with the memory holding function is connected (step S151), and if not connected, the power supply interruption routine to the memory with the memory holding function is ended (step S156), and the connection is established. If done,
It is determined whether or not the battery voltage is lower than the power supply cutoff setting voltage V3 to the memory with the memory retention function (step S15).
2). Here, if the battery voltage is not lower than V3,
Returning to the processing of step S151, if it is below the range, power supply to the memory is cut off (step S153). still,
The memory holding operation in this memory is maintained by the power supply inside the memory. After the power supply is cut off, it is determined whether or not the battery has been replaced or the external power source has been connected (step S154), and if the connection has been made, step S in FIG.
The main routine of 107 is reached (step S155),
If the connection is not established, the power supply cutoff routine to the memory is ended as described above, and the process proceeds to the further power saving mode (step S156).

As shown in the flowchart of FIG. 15 which is similar to FIG. 7, the limiting / feeding interruption cancellation routine processing in step S107 of FIG. 9 cancels all the limitations and feeding interruption (step S161), and then cancels the cancellation. This is the process of ending the routine (step S162). As a result, all the power supply switching units 9a to 9d in FIG. 1 are turned on, and the power from the battery is supplied to the mounting units 10a to 10d.

The system power-off routine in step S108 of FIG. 9 determines whether or not the battery has been exhausted and the battery voltage has dropped below the system power-off voltage V4, as shown in the flowchart of FIG. 16 similar to FIG. (Step S171) After waiting for the voltage to drop, the system power of its own is shut off (step S172).

Next, an embodiment of the power saving operation for operation restriction will be described with reference to the flowchart of FIG.
The present embodiment is an example of performing power saving by detecting types such as writing and reading, data searching and erasing.

When the processing is started, the power saving mode is input and stored by the operation input from the operation input recognition unit 8 (step S201), and then the operation is input (data retrieval, deletion, Write, read, etc.)
Is performed (step S202), access to the HDD and FDD is restricted (step S203), and the process proceeds to a process of shutting off the system power (step S204). If access is not restricted in step S203,
The process returns to step S201. Also, step S20
If there is no power saving mode input in step 1, step S
The process moves to 204.

The process of step S201 of FIG. 17 is the same as that of FIG.
As shown in the flowchart of FIG. 18 similar to the above, after the user inputs a power saving mode instruction with the switch of the operation input recognition unit 8 (step S211), it is determined whether or not the power saving mode is instructed. (Step S21
2) Only in the power saving mode, the power saving mode is input by the next operation input, and the storage routine is finished (step S
214), if it is not in the power saving mode, the process proceeds to the system power shutdown routine (step S213).

HD in step S203 of FIG.
The D and FDD access restriction routine will be described with reference to the flowchart of FIG.

First, it is determined whether or not the HDD or FDD is connected (step S221). If neither is connected, the routine cannot be executed.
The DD or FDD access restriction routine is terminated (step S229), and if either is connected, it is determined whether the operation input is for the HDD or FDD (step S222). If it is determined that the operation input is not for the HDD or FDD, the process proceeds to step S229. If it is determined that the operation input is for the HDD or FDD, the battery voltage is set to the HDD or FDD access limit voltage V7. It is judged whether or not it has fallen below (step S
223). If the battery voltage is not lower than V7, the process returns to step S221 to wait for the battery to be exhausted, and if it is lower than V7, it is determined whether the operation input is search or erase (step S224).

If it is determined in step S224 that the operation input is search or deletion, after the operation input to the HDD or FDD is executed (step S225), it is determined that the operation input is not search or deletion, that is, , When writing and reading data, HD
Ignoring operation input for D and FDD (step S22
After 6), it is determined whether or not the battery has been replaced or the external power source has been connected (step S227). If the connection has been made, the main routine is reached (step S22).
8) If not, the HDD / FDD access restriction routine ends (step S229).

In step S224, there are data retrieval, erasing, writing, and reading inputs, and step S22
In 5 and S226, data retrieval and erasing, and writing and reading are performed separately. This is because, for example, when writing and reading data with a large amount of data, the hard disk and floppy disk operate for a long time, power consumption increases, and the remaining capacity of the battery sharply decreases. On the other hand, data retrieval and deletion only requires rewriting some flags, so the operation can be completed in a short time. Therefore, whether the amount of data is large or small, searching and erasing are completed in a short time. As a result, only searching and erasing are allowed to be executed, and writing and reading of data take a long time when the data amount is large, and for example, a floppy disk may require several tens of seconds to one minute. In order to prevent such an operation, writing and reading are prohibited in order to maintain the remaining capacity of the battery.

The system power-off routine of FIG. 17 determines whether or not the battery has been consumed and the battery voltage has dropped below the system power-off voltage V4, as shown in the flowchart of FIG. 20 similar to FIG. 8 (step S231). ), Waits for the power to drop, and shuts off the system power (step S23).
2).

Next, an embodiment of the power saving operation for limiting the long-time access operation will be described with reference to the flowchart of FIG.

When the processing is started, the power saving mode is input and stored by the operation input (step S301).
After that, the operation is input by the operation input of the user (step S302), the access to the HDD and the FDD is restricted (step S303), and the system power is cut off (step S304). Incidentally, step S30
If there is no limitation in step 3, the process returns to step S301. If the power saving mode is not input in step S301, the process proceeds to step S304.

The process of step S301 of FIG. 21 is the same as that of FIG.
As shown in the flowchart of FIG. 2, after the user inputs a power saving mode instruction with the switch of the operation input recognition unit 8 (step S311), it is determined whether the power saving mode is instructed (step S312). Only in the power saving mode, the power saving mode is input by the next operation input, and the storage routine is ended (step S314). When the power saving mode is not set, the system power shutdown routine is started (step S313).

HD in step S303 of FIG.
The D and FDD access restriction routine will be described with reference to the flowchart of FIG.

First, it is determined whether or not the HDD or FDD is connected (step S321). If not connected, the HDD and FDD access restriction routine is ended (step S329). If connected, the HDD or FDD is connected. Alternatively, it is determined whether or not the operation input is for the FDD (step S322). Here, if it is determined that the operation input is to the HDD or FDD, the battery voltage is changed to the HDD or FD.
It is determined whether the voltage has dropped below the D access limit voltage V7 (step S323). If the battery voltage is not lower than V7, the process returns to step S321. If it is lower than V7, the time required for the operation is the access restriction setting time T.
It is determined whether or not it exceeds (step S324).

If it is judged in step S324 that the time T has not been exceeded and the data is to be accessed for a short time, it is judged that the data is not accessed after the operation input to the HDD and FDD is executed (step S325). That is, when the data is for a long time, after ignoring the operation input to the HDD and FDD (step S326),
It is judged whether or not the battery is replaced or the external power source is connected (step S327). If the connection is made, the main routine is reached (step S328). If not, the HDD and FDD access restriction routine is ended. Yes (step S329).
