Description

  The present invention relates to a power operation device that operates on electric power.

  In recent years, power operating devices have been developed that have been devised in various ways to save power. As an example of the power operation apparatus, there are techniques disclosed in Patent Documents 1 and 2.

  For example, in Patent Document 1, in a situation where external power cannot be stably obtained (for example, when a commercial power source cannot be used due to a power failure or on a remote island where electricity is not communicated), the power supply from the commercial power source is An ultrasonic diagnostic apparatus that can continue an ultrasonic examination by switching to power supply from an auxiliary power source built in the apparatus is disclosed.

  Patent Document 2 discloses an ultrasonic diagnostic apparatus that can reduce the influence of the power consumption for key illumination on the operating time by stopping or dimming the key illumination depending on the power supply status and the brightness of the environment.

  In addition, as an example of a power driving device that achieves power saving of the device, the technique of Patent Document 3 can be cited. In Patent Literature 3, in a gas detection system with a built-in power supply, a low power consumption sensor having sensitivity in a low concentration region is always operated, and high power consumption having a sensitivity in a high concentration region only when a certain threshold is exceeded. It is disclosed to operate the sensor.

JP 11-137545 A (published May 25, 1999) JP 2006-305303 A (published November 9, 2006) JP 2007-17208 A (released on January 25, 2007)

  However, when the external power supply state to the power operating device is in an environment where it is stopped or fluctuated for a relatively long time, even if the device has an internal power source such as a battery, it depends on the amount of power consumed by the device. In some cases, the apparatus stops before the power supply state is recovered, and the function of the apparatus that should be secured cannot be obtained.

  For example, the apparatus of Patent Document 1 switches to an auxiliary power source at the time of a power failure. However, since the amount of power that can be supplied by the auxiliary power source is generally small, there is a possibility that it cannot be used when the power failure is prolonged. In addition, Patent Document 1 discloses that a predetermined operation is restricted in order to maintain the function of the device and suppress the amount of power during a power failure, but to a member that can realize the function and has a small amount of power. It is not disclosed at all that switching is performed.

  Further, Patent Document 1 discloses only an ultrasonic diagnostic apparatus that switches a power supply source from a commercial power supply to an auxiliary power supply in a situation where external power cannot be stably obtained, and relates to a general power operation apparatus. No description is found, and a power operating device that can maintain a state in which a function that should be originally obtained is realized under a situation where external power cannot be stably obtained has not been realized.

  The device of Patent Document 2 changes the illumination of the key based on the ambient brightness and the remaining battery level, but includes a member that replaces the light source for realizing the function of illumination of the key. I don't mean. Therefore, in the apparatus, when the power supply to the light source is stopped, the above function cannot be realized, and it is impossible to maintain a state in which the function that should be originally obtained is realized.

  Moreover, in order to reduce the power consumption of the apparatus, the apparatus of Patent Document 3 operates the second gas sensor that consumes a large amount of power only when the gas concentration becomes high. In this case, the second gas sensor is operated. Not only the gas sensor is operated. Further, the apparatus does not operate the second gas sensor based on the power supply state to the first gas sensor in the first place.

  The present invention has been made to solve the above-described problem, and its purpose is to provide a power supply state to an operation unit that realizes a predetermined function even when the power supply state is stopped or becomes unstable for a relatively long period of time. An object of the present invention is to provide a power operation device capable of maintaining a state in which a function to be originally obtained is realized.

  In order to solve the above-described problem, the power operation device according to the present invention includes a first operation unit that performs an operation for realizing a predetermined function, and the first operation unit for realizing the predetermined function. Includes a second operation unit that performs different operations and consumes less power than the first operation unit, and further includes a power supply state determination unit that determines a power supply state to the first operation unit, and the power supply And operating unit control means for operating the first operating unit or the second operating unit based on the determination result of the state determining means.

  The power operating device control method according to the present invention includes a first operating unit that performs an operation for realizing a predetermined function, and the first operating unit for realizing the predetermined function. A power supply state determination step for determining a power supply state to the first operation unit, the second operation unit performing a different operation from the first operation unit and consuming less power than the first operation unit, and the power supply state And an operation unit control step for operating the first operation unit or the second operation unit based on the determination result in the determination step.

  According to the above configuration, the power operation device includes a first operation unit that performs an operation for realizing a predetermined function, an operation that realizes the predetermined function, but is different from the operation of the first operation unit, and the first operation unit A second operating unit that consumes less power than the operating unit.

  Therefore, a predetermined function can be realized by operating any of these operation units.

  Further, based on the determination result obtained by the power supply state determination means (power supply state determination step) determining the power supply state to the first operation unit, the operation unit control means (operation unit control step) is the first operation unit or the second operation unit. Operate the operating unit.

  For this reason, based on the power supply state to the first operation unit, either the first operation unit or the second operation unit can be operated to realize a predetermined function. In addition, the above processing of the power supply state determination unit and the operation unit control unit causes the power consumption to be reduced when the power supply state to the first operation unit is not good (power supply becomes unstable), for example. When two operating units are operated and become good again (power supply is stable), the first operating unit is operated to realize a predetermined function and respond to changes in the power supply state. Can do.

  Therefore, in the power operating device and its control method, even if the power supply state is stopped or unstable for a long period of time, a predetermined function can be realized with power saving, so that the power supply state is stabilized again. It is possible to reduce the possibility that the power operation apparatus will be stopped by the time. That is, even when the power supply state is stopped or unstable for a long period of time, it is possible to maintain a state in which a function that should be originally obtained is realized.

  In the power operation apparatus according to the present invention, it is preferable that the power supply state determination unit and the operation unit control unit are incorporated.

  According to the above configuration, the entire apparatus can be miniaturized by incorporating the power supply state determination unit and the operation unit control unit.

  In the power operating device according to the present invention, when the power supply state determination unit determines that the power supply state to the first operation unit is good, the operation unit control unit performs the first operation unit. It is preferable to operate the second operation unit when the power supply state determination unit determines that the power supply state to the first operation unit is not good.

  According to the above configuration, since the second operation unit that consumes less power is operated when the power supply state is not good, the possibility that the power operation device stops can be reduced.

  Further, the power operation device according to the present invention provides a third operation for performing a predetermined operation required when each of the first operation unit and the second operation unit performs an operation for realizing the predetermined function. Preferably, a unit is further provided, and the first operation unit and the second operation unit share the third operation unit.

  According to the above configuration, the power operation device shares the third operation unit that performs a predetermined operation necessary when the first operation unit and the second operation unit perform an operation for realizing a predetermined function. Yes. For this reason, since it is not necessary to provide each of the first operation unit and the second operation unit with an operation unit for performing the predetermined operation, an inexpensive power operation device can be manufactured.

  The power operating device according to the present invention further includes mode determining means for determining a power consuming operation mode of the third operating unit, wherein the mode determining means includes the first operating unit and the operating unit control means. The power consumption operation mode is preferably determined according to which of the second operation units is operated.

  According to the above configuration, the mode determination unit determines the power consumption operation mode of the third operation unit according to the first operation unit or the second operation unit operated by the operation unit control unit. For this reason, the third operation unit shared by the first operation unit or the second operation unit can be operated in accordance with the power supply amount required for the first operation unit or the second operation unit.

  In the power operation device according to the present invention, the first operation unit is supplied with power from outside the power operation device, and the second operation unit is supplied with power from an internal power supply included in the power operation device. Is preferred.

  According to the above configuration, since the first operation unit is supplied with electric power from the outside, the first operation unit can perform an operation for realizing a predetermined function regardless of the amount of power consumption. On the other hand, since the power is supplied to the second operation unit from the internal power source, for example, even when the external power supply is unstable, the second operation unit having relatively low power consumption is operated for a short period or a long period. Therefore, it is possible to maintain a state where a predetermined function is realized.

  The food storage device according to the present invention is a food storage device for storing food as the power operation device described above, wherein the first operation unit is a food cooling device for cooling food with a refrigerant. The second operation unit is a vacuum storage device that stores food by evacuating the inside of the device by compressing the gas in the device, and the third operation unit contains the refrigerant and the gas. A compressor capable of compression is preferable.

  According to the above configuration, the food storage device realizes the function that should be originally obtained even when the power supply state to the food cooling device is stopped or unstable for a long time, as in the case of the power operation device. Can be maintained. Further, since the compressor as the third operation unit is provided, the food storage device can be manufactured at a lower cost than when the food cooling device and the vacuum storage device are each provided with a compressor.

The second operation unit is a second cooling device that cools the interior by circulating and vaporizing the liquid, and the third operation unit is a compressor that can compress the refrigerant and the liquid. It is preferable.

  According to the above configuration, even in the indoor cooling device, as in the case of the power operation device described above, a function that should be originally obtained even when the power supply state to the first cooling device is stopped or becomes unstable for a long time is realized. Can be maintained. Moreover, since the compressor as a 3rd operation | movement unit is provided, an indoor cooling device can be manufactured cheaply compared with the case where a compressor is provided in each of a 1st cooling device and a 2nd cooling device.

  An information reproducing apparatus according to the present invention is an information reproducing apparatus for reproducing information recorded on an information recording medium as the power operating apparatus described above, wherein the first operation unit includes a first information recording apparatus. The first driving device is driven to reproduce information recorded on the medium, and the second operation unit is a second driving device driven to reproduce information recorded on the second information recording medium. The third operation unit is preferably a decoder capable of decoding information recorded on the first information recording medium and the second information recording medium.

  According to the above configuration, the information reproducing apparatus also realizes a function that should be originally obtained even when the power supply state to the first driving apparatus is stopped or unstable for a long time, as in the case of the power operating apparatus. Can be maintained. In addition, since the decoder as the third operation unit is provided, the information reproducing apparatus can be manufactured at a lower cost compared to the case where each of the first drive device and the second drive device is provided with a decoder.

  An information recording apparatus according to the present invention is an information recording apparatus for recording information recorded on an information recording medium as the power operation apparatus described above, wherein the first operation unit includes a first information recording apparatus.

Is preferably an encoder capable of encoding information recorded on the first information recording medium and the second information recording medium.

  According to the above configuration, the information recording apparatus also realizes a function that should be originally obtained even when the power supply state to the first drive apparatus is stopped or unstable for a long time, similarly to the power operation apparatus. Can be maintained. In addition, since the encoder as the third operation unit is provided, the information recording device can be manufactured at a lower cost than when the first drive device and the second drive device are each provided with an encoder.

  The power operation device according to the present invention performs a first operation unit that performs an operation for realizing a predetermined function, an operation different from the first operation unit for realizing the predetermined function, and A second operation unit that consumes less power than the first operation unit, and further includes a power supply state determination unit that determines a power supply state to the first operation unit, and a determination result of the power supply state determination unit And an operation unit control means for operating the first operation unit or the second operation unit. The operation unit control device is connected to an operation unit control device.

  According to the above configuration, the power operation device includes a first operation unit that performs an operation for realizing a predetermined function, an operation that realizes the predetermined function, but is different from the operation of the first operation unit, and the first operation unit A second operating unit that consumes less power than the operating unit.

  Therefore, a predetermined function can be realized by operating any of these operation units.

  Further, the operation unit control device has the operation unit control means (operation unit control step) based on the determination result of the power supply state determination means (power supply state determination step) determining the power supply state to the first operation unit. The first operation unit or the second operation unit is operated. The operation unit control device is connected to the power operation device.

  For this reason, the power operation device operates either the first operation unit or the second operation unit based on the power supply state to the first operation unit under the control of the connected operation unit control device. Function can be realized. In addition, by the control, for example, when the power supply state to the first operation unit is not good (the power supply becomes unstable), the second operation unit with low power consumption is operated and becomes good again. When the power supply is stable, by operating the first operation unit, a predetermined function can be realized and a change in the power supply state can be dealt with.

  Therefore, in the power operating device and its control method, even if the power supply state determination unit and the operation unit control unit are not provided, the power supply state is stopped for a long time by the control of the connected operation unit control device. Even if it becomes unstable, a predetermined function can be realized with low power consumption. For this reason, the possibility that the power operation apparatus stops before the power supply state is stabilized again can be reduced. That is, even when the power supply state is stopped or unstable for a long period of time, it is possible to maintain a state in which a function that should be originally obtained is realized.

  Moreover, since it is possible to separate the manufacturing process of the power operation device and the operation unit control device, it is possible to prevent the yield from being deteriorated and to reduce the manufacturing cost, compared with the case where the manufacturing process is not separated.

A second operation unit that operates and consumes less power than the first operation unit, and further includes a power supply state determination means for determining a power supply state to the first operation unit, and the power supply state determination Based on the result of the determination of the means, the operation unit control means comprises an operation unit control means for operating the first operation unit or the second operation unit.

  An embodiment of the present invention will be described below with reference to FIGS. For convenience of explanation, members having the same functions as those shown in the drawings are denoted by the same reference numerals, and description thereof is omitted.

[Configuration of Power Operation Device 1]
First, the power operation device 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating an example of a schematic configuration of a power operation device 1 according to the present embodiment.

  The power operation apparatus 1 according to the present embodiment is an apparatus that performs various functions by operating with power supplied from the external power supply 2 or the internal power supply 14. As shown in FIG. 1, the power operation apparatus 1 mainly includes a first operation unit 11, a second operation unit 12, a third operation unit 13, an internal power supply 14, a control unit 15, and a storage unit 16.

  The first operation unit 11 is a unit that performs an operation for realizing a predetermined function. This predetermined function is, for example, a power function such as a cooling function for food or indoors (Examples 1 and 2 described later), a function for recording or reproducing information recorded on an information recording medium (Example 3 described later), and the like. The device 1 refers to at least one of various functions for achieving the purpose of the device. In the present embodiment, the first operation unit 11 is supplied with power from the external power source 2 (outside of the power operation device 1).

  The second operation unit 12 is a unit that performs an operation different from that of the first operation unit 11 in order to realize the predetermined function and consumes less power than the first operation unit 11. That is, the second operation unit 12 also realizes almost the same function as the function that the first operation unit 11 should realize. When the power supply state to the first operation unit 11 is not good (unstable), the second operation unit 12 temporarily continues the predetermined function realized by the first operation unit 11 with low power. Any configuration can be used.

  In general, when a power operating device includes an internal power supply, the amount of power that the internal power supply has is limited, so the amount of power that can be supplied to each part of the device is less than the amount of power that can be supplied by an external power supply. For this reason, if it is in the situation which can receive electric power supply from an external power supply (commercial power supply), it is preferable to receive electric power supply from the said external power supply as much as possible, and to use an electric power operating apparatus.

  Also in the present embodiment, the power operation device 1 is configured such that each unit (other than the second operation unit 12) operates by power supply from the external power source 2 when the power supply state from the external power source 2 is good. Has been. On the other hand, when the power supply state becomes unsatisfactory, each part (other than the first operation unit 11) is configured to operate by supplying power from the internal power supply 14.

  In particular, in the power operating device 1, for the first operating unit 11 and the second operating unit 12 that realize substantially the same function, the power supply state from the external power source 2 to the first operating unit 11 is good. Operates the first operation unit 11 in preference to the second operation unit 12, and operates the second operation unit 12 instead of the first operation unit 11 when it is not good. That is, in the present embodiment, it is not necessary to supply power from the external power supply 2 to the second operation unit 12.

  Here, “the power supply state is good” means that each part of the power operation device 1 (particularly the first operation unit 11) is supplied with power sufficient to satisfy the power necessary for the operation. That is, it refers to a state in which each unit such as the first operation unit 11 can perform an operation for realizing each function.

  The third operation unit 13 is a unit that performs a predetermined operation required when each of the first operation unit 11 and the second operation unit 12 performs an operation for realizing the predetermined function. It is shared as a part of the operation unit 11 and the second operation unit 12. In FIG. 1, the shared state is indicated by a dotted frame.

  That is, the third operation unit 13 is a unit that realizes a common operation performed by the first operation unit 11 and the second operation unit 12 in order to realize substantially the same function. According to this configuration, since there is no need to provide an operation unit for performing a predetermined operation in each of the first operation unit and the second operation unit, an inexpensive power operation device can be manufactured.

  Further, the third operation unit 13 has two operation modes (power consumption operation modes) having different power consumption amounts, ie, “normal mode” and “power saving mode”. The first operation unit 11 and the second operation unit 12 differ in the amount of power required to realize a predetermined function, and an operation according to each amount of power is performed. Therefore, the predetermined operation by the third operation unit 13 is also performed in accordance with the power amount of each operation unit.

  Here, the “normal mode” is an operation mode when the first operation unit 11 is operating. At this time, the third operation unit 13 performs an operation for the first operation unit 11 to realize a predetermined function, and power necessary for the operation is supplied from the external power source 2 to the unit. On the other hand, the “power saving mode” is an operation mode when the second operation unit 12 is operating. At this time, the third operation unit 13 performs an operation for the second operation unit 12 to realize a predetermined function, and power necessary for the operation is supplied from the internal power supply 14 to the unit.

  In addition, the operation units (operation start, operation stop, operation mode, etc.) of the first to third operation units 11 to 13 are controlled by the operation unit control unit 153 of the control unit 15. Specific examples of the first to third operation units 11 to 13 will be described later.

  The internal power supply 14 supplies power to the second operation unit 12 and the third operation unit 13 when the second operation unit 12 operates. When the power supply state to the first operation unit 11 is not good, the internal power supply 14 is provided with the second operation unit 12 and the third operation unit 13 in order to obtain a predetermined function realized by the first operation unit 11. It is only necessary to be able to supply enough power to operate the system in the short term or in the long term.

  As described above, the internal power supply 14 can supply power to each part (each part other than the first operation unit 11) of the power operation device 1 when, for example, power supply from the external power supply 2 is not satisfactory. A simple power source may be used.

  The control unit 15 mainly includes a power supply state determination unit 151 (power supply state determination unit), a power supply control unit 152, an operation unit control unit 153 (operation unit control unit), and a mode determination unit 154 (mode determination unit). ing. The control part 15 controls the member which comprises the electric power operating apparatus 1, for example by running a control program. The control unit 15 reads the program stored in the storage unit 16 into a primary storage unit (not shown) configured by, for example, a RAM (Random Access Memory), and executes the program to the first operation unit 11. Various processes such as confirmation of the power supply state, operation control or mode control of the first to third operation units 11 to 13 are performed.

  The power supply state determination unit 151 determines whether or not the power supply state to the first operation unit 11 is good. The power supply state determination unit 151 determines whether the power supply amount from the external power source 2 satisfies a predetermined threshold or whether the power supply is stopped or not based on whether the power supply state is good (normal) / bad (abnormal). Make a decision. The reference is not limited to the presence or absence of the power supply to the first operation unit 11 or the power supply amount, but the first value such as the voltage value measured by the external power source 2 or the first operation unit 11, the amount of voltage value fluctuation, etc. Any standard that can determine the state of power supply to the operation unit 11 may be used. The power supply state determination unit 151 transmits the determination result to the power supply control unit 152.

  The power supply control unit 152 controls the power supply amount to the first to third operation units 11 to 13. In particular, the power supply control unit 152 determines whether or not to supply power to the second operation unit 12 based on the determination result of the power supply state determination unit 151, and in accordance with the determination, the internal power supply 14 To control.

  Specifically, the power supply control unit 152 supplies power to the second operation unit 12 when the power supply state determination unit 151 determines that the power supply state to the first operation unit 11 is good. Is stopped (or maintained in a stopped state). On the other hand, when it is determined that it is not good, the power supply to the second operation unit 12 is started. The power supply control unit 152 transmits the determination result to the operation unit control unit 153. The power supply control unit 152 also controls power supply to the third operation unit 13 in accordance with the operation mode determined by the mode determination unit 154. Accordingly, the third operation unit 13 can perform a predetermined operation as a part of the first operation unit 11 or the second operation unit 12.

  The operation unit control unit 153 controls each operation of the first to third operation units 11 to 13 based on the determination result of the power supply control unit 152 (that is, the determination result of the power supply state determination unit 151). is there.

  Specifically, the operation unit control unit 153 starts (or maintains) the operation of the first operation unit 11 when the power supply control unit 152 determines not to supply power to the second operation unit 12. To do. On the other hand, when it is determined to supply power to the second operation unit 12, the operation of the first operation unit 11 is stopped and the operation of the second operation unit 12 is started.

  In other words, the operation unit control unit 153 operates the first operation unit 11 when the power supply state determination unit 151 determines that the power supply state to the first operation unit 11 is good, and determines that it is not good. When it is done, the second operation unit 12 is operated. Thereby, when the said electric power supply state is not favorable, a 2nd operation | movement unit with little power consumption can be operated, and possibility that the electric power operation apparatus 1 will stop can be reduced.

  That is, the power operating device 1 has a lower power consumption than the first operating unit 11 even when the power supply to the first operating unit 11 is not good and the first operating unit 11 does not operate normally. By switching to the operation of the two-operation unit 12, it is possible to maintain a state in which functions that should be originally obtained as the power operation device 1 are realized. For example, in an environment where power supply from the external power supply 2 is stopped or fluctuates, a predetermined function can be maintained for a relatively long period until the power supply state is restored. Moreover, it can respond to the change in the power supply state.

  Further, the operation unit control unit 153 performs the operation mode switching process of the third operation unit 13 under the control of the mode determination unit 154. Therefore, the operation unit control unit 153 notifies the mode determination unit 154 of the first operation unit 11 or the second operation unit 12 that is operating.

  In FIG. 1, the operation unit control unit 153 performs the above-described operation control based on the determination result of the power supply control unit 152. However, the operation unit control unit 153 directly receives the determination result from the power supply state determination unit 151 and performs the determination. Based on the result, each of the first to third operation units 11 to 13 may be controlled.

  The mode determination unit 154 determines the operation mode of the third operation unit 13 according to which of the first operation unit 11 and the second operation unit 12 is operated by the operation unit control unit 153. Thereby, the power operation apparatus 1 can operate the third operation unit 13 according to the power supply amount required for the first operation unit 11 or the second operation unit 12.

  Specifically, when the mode determination unit 154 receives a notification of an operation unit in an operation state, the mode determination unit 154 determines an operation mode corresponding to the operation unit, and notifies the operation unit control unit 153 of the operation mode. When the first operation unit 11 is in the operation state, the “normal mode” is determined as the operation mode, and when the second operation unit 12 is in the operation state, the “power saving mode” is determined as the operation mode. The operation mode is stored in the storage unit 16 in association with the operation unit, for example, and the mode determination unit 154 refers to the storage unit 16 to determine the operation mode. In order to adjust the power supply amount to the third operation unit 13, the mode determination unit 154 also notifies the power supply control unit 152 of the determined operation mode.

  In addition, the storage unit 16 records (1) a control program for each unit, (2) an OS program, (3) an application program, and (4) various data to be read when the program is executed. To do. The control unit 15 is configured by a nonvolatile storage device such as a ROM (Read Only Memory) flash memory. The primary storage unit described above is configured by a volatile storage device such as a RAM. However, in this embodiment, the storage unit 16 may be described as having the function of a primary storage unit. . The storage unit 16 stores, for example, a table in which the operation unit, the operation mode of the third operation unit, and the power supply amount to each operation unit are associated with each other.

  In the present embodiment, as shown in FIG. 1, the first operation unit 11 is supplied with power from an external power source 2 (outside of the power operation device 1), and the second operation unit 12 is provided with an internal power source 14. Power is supplied.

  In general, since the amount of power that the internal power supply has is limited, it is difficult to supply power from the internal power supply for a long time even when it is used with some power saving. On the other hand, the external power supply can be performed for a long time as long as the supply state does not become unstable.

  For this reason, the first operation unit 11 can perform an operation for realizing a predetermined function regardless of the power consumption. That is, by supplying power from the external power supply 2, it is possible to cause the first operation unit 11 to perform complicated processing to realize a predetermined function, for example. On the other hand, for example, even when the power supply from the external power supply 2 to the first operation unit 11 is unstable, the second operation unit 12 with relatively low power consumption can be operated over a short period or a long period. The state where the function is realized can be maintained. If this point is not taken into account, power may be supplied to the first operation unit 11 from, for example, a dedicated internal power supply.

  Note that the first operation unit 11 and the second operation unit 12 do not necessarily need to include the third operation unit 13 unless consideration is given to the manufacture of an inexpensive power operation device. In this case, it is not necessary to include the mode determination unit 154 that determines the operation mode of the third operation unit 13 or to store a table in which the operation unit and the operation mode are associated with each other. Further, the operation unit control unit 153 may function as a device that operates the first operation unit 11 or the second operation unit 12 based on at least the determination result of the power supply state determination unit 151.

[Processing flow in the power operating device 1]
Next, based on FIG. 2, the flow of the switching process of the first operation unit 11 and the second operation unit 12 in the power operation device 1 will be described. FIG. 2 is a flowchart illustrating an example of a process flow in the power operation apparatus 1.

  First, the process of FIG. 2 will be described on the assumption that the first operating unit 11 is supplied with power from the external power supply 2 and the first operating unit 11 is in an operating state. In this case, the power supply control unit 152 confirms the power supply state to the first operation unit 11 (S1), and determines whether or not the state is good (S2).

  When it is determined that the power supply is not good (NO in S2), the power supply control unit 152 determines to supply power from the internal power supply 14 to the second operation unit 12, and starts the power supply (S3). The operation unit control unit 153 operates the second operation unit 12 (S4), and sets the operation mode of the third operation unit 13 to the power saving mode according to the determination of the operation mode by the mode determination unit 154 (S5). . That is, when it is determined that the power supply state to the first operation unit 11 is not good, the power supply to the second operation unit 12 is started, the operation is switched to the operation of the second operation unit 12, and the third operation is started. The operation mode of the unit 13 is switched to the power saving mode.

  On the other hand, if it is determined that it is good (YES in S2), the first operation unit 11 is already in an operating state, so that the processing of S6 to S8 described later is not performed and the processing returns to S1. In the case of YES in S2, in order to monitor the power supply state to the first operation unit 11 every predetermined time, the processes of S1 and S2 are repeated every time.

  Next, the process of FIG. 2 will be described on the assumption that the process of S5 is performed and the second operation unit 12 is in an operating state. Similarly to the above, the power supply state determination unit 151 determines whether the power supply state to the first operation unit 11 is good (S2). If it is not good (NO in S2), the second operation unit 12 is already in an operating state, and thus the processes of S3 to S5 described above are not performed. Although not shown, in this case as well, the process returns to the process of S1 after the process of S5, and the power supply state to the first operation unit 11 is monitored every predetermined time.

  On the other hand, if it is good (YES in S2), it is determined that the power supply state to the first operation unit 11 has been recovered, and the power supply control unit 152 stops the power supply to the second operation unit 12 (S6). ). In addition, the operation unit control unit 153 operates the first operation unit 11 according to the determination of stopping the power supply to the second operation unit 12 (S7), and the operation unit control unit 153 operates the first operation unit 11 according to the determination of the operation mode by the mode determination unit 154. The operation mode is set to the normal mode (S8). That is, when the power supply state to the first operation unit 11 is restored, the power supply to the second operation unit 12 is stopped, and the operation of the first operation unit 11 is switched to the operation of the third operation unit 13. Switch the mode to normal mode.

  Thereby, even when the power supply state becomes unsatisfactory, a predetermined function can be realized by the second operation unit 12 and a change in the power supply state can be dealt with. Further, since the second operation unit 12 consumes less power than the first operation unit 11, even if the power supply state is not good for a long period, the second operation unit 12 can realize a predetermined function during that period. it can. That is, it is possible to maintain a state in which a function that should be originally obtained as the power operation device 1 is realized for a long period of time.

[Effect of the power operating device 1]
As described above, the power operation device 1 realizes at least the first operation unit 11 and substantially the same function as the first operation unit 11, performs an operation different from the first operation unit 11, and performs the first operation. And a second operation unit 12 that consumes less power than the unit 11. In addition, a power supply state determination unit 151 that determines a power supply state to the first operation unit 11 and an operation unit control unit 153 that operates the first operation unit 11 or the second operation unit 12 based on the determination result. Prepare.

  With this configuration, even when the power supply state to the first operation unit 11 used for realizing the predetermined function is stopped or unstable for a long time, the function is saved in the second operation unit 12 that saves power. Can be realized. As a result, it is possible to maintain a state in which the function that should be originally obtained as the power operation device 1 is realized during the stop period or the unstable period.

  In addition, the power operation apparatus 1 includes a power supply state determination unit 151 and an operation unit control unit 153. According to this configuration, for example, the size of the device can be reduced as compared with the case where these members are provided as external control or as a control circuit different from the control unit of the power operation device 1.

[Modification (Part 1)]
As described above, the power operating device 1 may receive power supply from a dedicated internal power supply instead of the first operating unit 11 receiving power supply from the external power supply 2. FIG. 3 is a block diagram showing a power operation device 1 a which is a modification of the power operation device 1.

  As shown in FIG. 3, the power operating device 1a includes an internal power source 14a. The internal power supply 14 a supplies power to the first operation unit 11 instead of the external power supply 2. In the power operation device 1a, normally, the first operation unit 11 realizes a predetermined function, and the power supply state to the first operation unit 11 is not good (for example, while the internal power supply 14a is charged). The predetermined function is realized by the second operation unit 12. For this reason, it is preferable that the electric energy of the internal power supply 14a is larger than the electric energy of the internal power supply 14.

  For example, when the power supply state determination unit 151 determines that the power supply from the internal power supply 14a is not good (for example, when it is recognized that the internal power supply 14a is lower than a predetermined voltage value), the power supply control unit 152 stops the power supply from the internal power supply 14 a to the first operation unit 11, and starts the power supply from the internal power supply 14 to the second operation unit 12. In addition, the operation unit control unit 153 stops the first operation unit 11 and activates the second operation unit 12. That is, the operation is switched from the operation of the first operation unit 11 to the operation of the second operation unit 12.

  As a result, even in the power operation device 1a, even when the situation in which the first operation unit 11 cannot be continuously driven is for a relatively long period, a predetermined function is maintained by the second operation unit 12 during that period. be able to.

[Modification (Part 2)]
In the above description, the configuration in which the control unit 15 and the storage unit 16 are provided in the power operation device 1 has been described. However, these may be realized in a device different from the power operation device 1. FIG. 4 is a block diagram showing a power operation device 1 b which is a modification of the power operation device 1, and shows a configuration in which the power operation device 1 b receives control from the operation unit control device 3.

  As shown in FIG. 4, the power operation device 1 b includes first to third operation units 11 to 13 and an internal power supply 14, and the first operation unit 11 and the first operation unit 11 according to the power supply state of the first operation unit 11. In this configuration, the control unit 15 and the storage unit 16 that perform the switching process of the second operation unit 12 are not provided. In addition, although not shown in figure, the electric power operating apparatus 1b is provided with the control part and memory | storage part for performing processes other than the said switching process.

  Instead, the operation unit control device 3 includes a control unit 15 and a storage unit 16 for realizing the switching process, and performs the switching process from the outside of the power operation device 1b.

  In other words, the power operation device 1b includes the first operation unit 11 and the second operation unit 12, and is connected to the operation unit control device 3 including the power supply state determination unit 151 and the operation unit control unit 153. . Even if it is this structure, there exists an effect similar to said electric power operating apparatus 1 by receiving control from the operating unit control apparatus 3 which is an external apparatus of the electric power operating apparatus 1b. In addition, since it is possible to separate the manufacturing process of the power operation device 1b and the operation unit control device 3 that performs the switching process, compared to the case where the manufacturing process is not separated, the yield is prevented from deteriorating and the manufacturing cost is reduced. Can be lowered.

  Below, the specific example of the apparatus with which the electric power operating apparatus 1 is implement | achieved is demonstrated in Examples 1-3. In the first to third embodiments, the power operation device 1 is described as including the third operation unit 13, but as described above, it is not always necessary to include the third operation unit 13.

[Example 1]
First, the power operating device 1 can be realized as a food storage device that stores food. In this case, each of the first operation unit 11, the second operation unit 12, and the third operation unit 13 shown in FIG. 1 includes a food cooling device that cools food with a refrigerant, and a gas in the device by compressing the gas in the device. It functions as a compressor capable of compressing a refrigerant used in a vacuum storage device and a food cooling device for storing food in a vacuum state and a gas used in the vacuum storage device.

  The food cooling device that functions as the first operation unit 11 is realized by, for example, a refrigerator or a freezer, and the vacuum storage device that functions as the second operation unit 12 is realized by, for example, a storage container to which a vacuum pump is connected. The compressor functioning as the third operation unit 13 is a device having a function common to the first operation unit 11 and the second operation unit 12, that is, a compression function.

  For the basic structure of these devices, a well-known configuration can be employed. As for the compressor, the storage container receives the predetermined power supply in the “normal mode” to compress the refrigerant in the refrigerator (freezer) and receives less power supply in the “power saving mode” than in the “normal mode”. It is configured to compress the gas inside.

  The food storage device according to the present embodiment, when the power supply state to the refrigerator is not good, compresses the gas in the storage container instead of compressing the refrigerant to make the inside of the food storage device in a vacuum state . Thereby, even if it is a case where a refrigerator does not function, it can be preserve | saved for a long time, without rotting food. Further, since the refrigerator and the storage container share a compressor that performs an operation (that is, compression of refrigerant or gas) necessary for realizing a predetermined function (food storage function), each of the refrigerator and the storage container Compared with the case where has a separate compressor, an inexpensive food storage device can be provided.

[Example 2]
Next, the power operation device 1 can also be realized as an indoor cooling device that cools the interior. In this case, each of the first operation unit 11, the second operation unit 12, and the third operation unit 13 shown in FIG. 1 is a first cooling device that cools the room with a refrigerant, and cools the room by circulating and vaporizing the liquid. It functions as a compressor capable of compressing the refrigerant used in the second cooling device, the first cooling device, and the liquid used in the second cooling device.

  The 1st cooling device which functions as the 1st operation unit 11 is implement | achieved by the air conditioner etc., for example, and should just have a cooling function at least. The 2nd cooling device which functions as the 2nd operation unit 12 is realized by a cold wind fan etc., for example. The compressor functioning as the third operation unit 13 is a device shared by the first cooling device and the second cooling device.

  For the basic structure of these devices, a well-known configuration can be employed. As for the compressor, the air conditioner refrigerant is compressed by receiving a predetermined power supply in the “normal mode”, and the cooler fan liquid is supplied in the “power saving mode” by receiving less power than in the “normal mode”. It is configured to compress.

  In the indoor cooling device of the present embodiment, when the power supply state to the air conditioner is not good, the cold air fan cools the room indoors instead of the air conditioner. Thereby, even if the air conditioner does not function, the indoor space can be cooled or maintained at a constant low temperature for a relatively long time. In addition, since the air conditioner and the cold air fan share a compressor that performs an operation (that is, compression of refrigerant or liquid) necessary for realizing a predetermined function (indoor cooling function), each of the air conditioner and the cold air fan Compared to the case where has a compressor, an inexpensive indoor cooling device can be provided.

Example 3
Next, the power operation apparatus 1 can be realized as an information reproducing apparatus that reproduces information recorded on the information recording medium and / or an information recording apparatus that records information on the information recording medium.

  In this case, the first operation unit 11 shown in FIG. 1 functions as a first driving device that is driven to reproduce information recorded on the first information recording medium or to record information on the first information recording medium. To do. The second operation unit 12 functions as a second driving device that is driven to reproduce information recorded on the second information recording medium or to record information on the second information recording medium. The third operation unit 13 is recorded on a decoder capable of decoding information recorded on the first information recording medium and the second information recording medium, or recorded on the first information recording medium and the second information recording medium. It functions as an encoder capable of encoding information.

  Here, the first information recording medium is a medium to be recorded / reproduced by the first driving device, and examples thereof include an optical disk such as a Blu-ray disc (registered trademark) and a DVD. On the other hand, the second information recording medium is a medium on which recording / reproduction is performed by a second driving device that consumes less power than driving the first information recording medium, and includes, for example, a memory card.

  In this case, the first drive device that functions as the first operation unit 11 is realized by, for example, an optical disk drive, and the second drive device that functions as the second operation unit 12 is realized by, for example, a memory card drive. The decoder or encoder that functions as the third operation unit 13 is a device shared by the first drive device and the second drive device.

  For the basic structure of these devices, a well-known configuration can be employed. As for the decoder / encoder, the information on the optical disc is decoded by receiving a predetermined power supply in the “normal mode” or the information to be recorded on the optical disc is encoded, and less in the “power saving mode” than in the “normal mode”. When power is supplied, the memory card information is decoded or the information recorded on the memory card is encoded.

  In the information reproducing apparatus or information recording apparatus of the present embodiment, when the power supply state to the optical disk drive becomes poor, the memory card drive operates instead of the optical disk drive, and records or reproduces information on the memory card. .

  In addition, for example, when content is recorded at different compression rates on the optical disc and the memory card, the decoder accordingly decodes the information read from the optical disc (processing for high resolution), In the case of information reproduction, decoding processing (low resolution processing) is performed on information read from the memory card.

  On the other hand, for example, in the case of recording information on an optical disc, the encoder performs an encoding process for high resolution such as high definition (maintaining high resolution), and in the case of recording information on a memory card, the encoding process for low resolution such as one segment. (Or encoding processing performed with low compression).

  In general, the capacity of an optical disk is larger than the capacity of a memory card. For this reason, the decoder or encoder functioning as the third operation unit 13 changes the information format (that is, resolution, transfer rate, etc.) according to the difference in capacity, and is read from these media, or is stored in the media. The recorded information can be decoded or encoded, and there is a difference in power consumption at that time. That is, by making the processing of the decoder or encoder (change of the above format) correspond to the operation mode at the time of encoding or the operation mode at the time of decoding corresponding to different media, a difference in power consumption occurs, It is possible to save power when recording or reproducing information. This information refers to, for example, an image or a moving image included in the content.

  With the above configuration, even when the optical disk drive does not function, information reproduction or information recording on the memory card is performed for a relatively long time (for example, longer than 6 hours realized in the conventional DVD drive). be able to. This is because it is possible to realize the information reproduction or information recording in a state where the optical disk rotation mechanism of the optical disk drive with a large power consumption does not operate. In addition, since the optical disk drive and the memory card drive share a decoder or encoder that performs an operation (decoding or encoding process) necessary for realizing a predetermined function (information reproduction or information recording function for an information recording medium), Compared to the case where each of the optical disk drive and the memory card drive has a decoder or an encoder, an inexpensive information reproducing apparatus or information recording apparatus can be provided.

  Hereinafter, a more detailed configuration and processing when the power operation device 1 functions as an information reproducing device and / or an information recording device will be described with reference to FIGS. Hereinafter, the power operating device 1 that functions as an information reproducing device and / or an information recording device will be described as a recording / reproducing device 10.

<Configuration of recording / reproducing apparatus 10>
The recording / reproducing apparatus 10 of the present embodiment is configured to be able to perform the processes shown in FIGS. The process of FIGS. 7 to 15 shows the process of the power operation apparatus 1 shown in FIG. 2 as a specific process that is suitable when the recording / reproducing apparatus 10 reproduces or records information such as contents.

  First, a schematic configuration of the recording / reproducing apparatus 10 will be described with reference to FIG. FIG. 5 is a block diagram illustrating an example of a schematic configuration of the recording / reproducing apparatus 10. The recording / reproducing apparatus 10 performs information reproduction or information recording on an optical disk or a memory card, and mainly includes an optical disk drive 21 (first operation unit 11 shown in FIG. 1) and a memory card drive 22 (second operation shown in FIG. 1). Operation unit 12), decoder 231 (third operation unit 13 shown in FIG. 1), encoder 232 (third operation unit 13 shown in FIG. 1), internal power supply 24, control unit 25, storage unit 26, operation unit 27, display A unit 28 and a speaker 29 are provided. In FIG. 5, an optical disc 30 (information recording medium, first information recording medium) is inserted in an optical disc insertion slot (not shown), and a memory card 31 (information recording medium, second information recording is inserted in a memory card insertion slot (not shown). Medium) is inserted.

  In the recording / reproducing apparatus 10 of the present embodiment, the memory card 31 is used as a recording medium in place of the optical disk 30. However, the present invention is not limited to this, and various types of semiconductor memories such as ROM (flash memory) and RAM may be used. Good.

  The internal power supply 24 realizes the same function as that of the internal power supply 14, and a description thereof will be omitted. Further, since the optical disk drive 21, the memory card drive 22, the decoder 231, the encoder 232, the optical disk 30, and the memory card 31 have been described above, description thereof will be omitted. Further, the storage unit 26 realizes the same function as the storage unit 16 and, when the recording / reproducing apparatus 10 functions as a recording apparatus, functions as a buffer (buffering) that temporarily stores broadcast content. Function).

  Further, when the recording / reproducing apparatus 10 functions only as an information reproducing apparatus, the third operating unit 13 may be provided with only the decoder 231. When the recording / reproducing apparatus 10 functions only as the information recording apparatus, the third operating unit 13 is provided. Only the encoder 232 may be provided.

  The operation unit 27 acquires a user operation and is configured by, for example, a touch panel. The display unit 28 displays content recorded on, for example, the optical disc 30 or the memory card 31, and the speaker 29 outputs sound when the content is displayed. The operation unit 27, the display unit 28, and the speaker 29 are each controlled by the control unit 25 and may be connected as an external device of the recording / reproducing apparatus 10.

  The control unit 25 controls, for example, members constituting the power operating device 1 by executing a control program, and mainly includes a power supply state determination unit 251 (power supply state determination unit) and a power supply control unit 252. And an operation unit control unit 253 (operation unit control means) and a mode determination unit 254 (mode determination means). The main functions of the power supply state determination unit 251, power supply control unit 252, and mode determination unit 254 are the same as those of the power supply state determination unit 151, power supply control unit 152, and mode determination unit 154 described above. The detailed explanation is omitted. Details of the operation unit control unit 253 will be described below.

<Details of Operation Unit Control Unit 253>
Next, the configuration of the operation unit control unit 253 will be described with reference to FIG. FIG. 6 is a block diagram illustrating an example of a schematic configuration of the operation unit control unit 253. In addition, since the function similar to the operation unit control part 153 was mentioned above among the functions of the operation unit control part 253, the description is abbreviate | omitted.

  As shown in FIG. 6, the operation unit controller 253 mainly includes an optical disk drive controller 4 that controls the optical disk drive 21, a memory card drive controller 5 that controls the memory card drive 22, and a decoder 231 or an encoder 232. And a decoder / encoder control section 6 for controlling.

  The optical disk drive control unit 4 mainly includes a loading confirmation unit 41, a reproduction control unit 42, a recording control unit 43, a capacity confirmation unit 44, a reproduction state confirmation unit 45, and a recording state confirmation unit 46.

  The loading confirmation unit 41 confirms whether or not the optical disk 30 has been inserted into the optical disk insertion slot. For example, a sensor for determining the presence or absence of the optical disc 30 is attached to the optical disc insertion slot, and loading confirmation of the optical disc 30 is performed by a signal received from the sensor.

  The reproduction control unit 42 controls the optical disc drive control unit 4 in order to reproduce information (contents, attribute management information, etc.) recorded on the optical disc 30.

  The recording control unit 43 controls the optical disc drive control unit 4 in order to record information (contents and the like) recorded in the storage unit 26 or the memory card 31 on the optical disc 30.

  The capacity confirmation unit 44 confirms the remaining capacity (free capacity) of the optical disc 30. For example, in a predetermined area of the optical disc 30, attributes that collectively manage attributes such as a name, capacity (size), creation date / time, and update date / time added to each information (file) recorded in the optical disc 30 are recorded. Management information is recorded. The capacity confirmation unit 44 instructs the reproduction control unit 42 to read out the attribute management information, thereby calculating the remaining capacity of the optical disc 30 from the used capacity indicated in the attribute management information read by the reproduction control unit 42.

  The reproduction state confirmation unit 45 confirms whether the reproduction control unit 42 is reproducing information on the optical disc 30 (that is, whether reproduction is in progress).

  The recording state confirmation unit 46 confirms whether or not the recording control unit 43 is recording information on the optical disc 30 (that is, recording is in progress). Further, the recording state confirmation unit 46 confirms whether or not content recording on the optical disc 30 by the recording control unit 43 is completed.

  The memory card drive control unit 5 mainly includes a second reproduction control unit 51, a second recording control unit 52, a second capacity confirmation unit 53, and a content presence / absence confirmation unit 54.

  The second reproduction control unit 51 controls the memory card drive control unit 5 in order to reproduce information (contents, attribute management information, etc.) recorded on the memory card 31. In the present embodiment, particularly when the second capacity confirmation unit 53 confirms the remaining capacity of the memory card 31 or when the content presence / absence confirmation unit 54 confirms the presence / absence of information (content) recorded in the memory card 31. Used when doing.

  The second recording control unit 52 controls the memory card drive control unit 5 in order to record information (contents and the like) recorded on the storage unit 26 or the optical disc 30 on the memory card 31.

  The second capacity confirmation unit 53 confirms the remaining capacity of the memory card 31. For example, in a predetermined area of the memory card 31, as with the optical disc 30, attribute management information that collectively manages attributes of information recorded on itself is recorded. The second capacity confirmation unit 53 calculates the remaining capacity by instructing the second reproduction control unit 51 to read the attribute management information.

  The content presence / absence confirmation unit 54 confirms the presence / absence of information (content) recorded in the memory card 31. For example, content is recorded in a content recording area different from a predetermined area in which attribute management information of the memory card 31 is recorded. The content presence / absence confirmation unit 54 instructs the second reproduction control unit 51 to read the content, so that “content is present” when the content read by the second reproduction control unit 51 is read, and when the content cannot be read. It is determined that there is no content.

  Although not specifically described in the present embodiment, the memory card drive control unit 5 confirms whether or not the memory card drive controller 5 is reproducing the same function as the reproduction state confirmation unit 45 and the recording state confirmation unit 46, that is, information on the memory card 31. It is preferable to include a reproduction state confirmation unit that performs recording and a recording state confirmation unit that confirms whether information is being recorded on the memory card 31.

  When the recording / reproducing apparatus 10 functions as a reproducing apparatus, it is not necessary to include at least the recording control unit 43, the recording state confirmation unit 46, and the capacity confirmation unit 44. Further, when the recording / reproducing apparatus 10 functions as a recording apparatus, it is not necessary to include at least the reproduction state confirmation unit 45.

  In addition, the operation unit control unit 253 reduces the luminance of the image displayed on the display unit 28 when the power supply state from the external power supply 2 is not good, reduces the resolution of the image at the time of decoding, and the sound from the speaker 29. It is also possible to have a function of performing processing such as outputting only

<Processing Flow in Recording / Reproducing Apparatus 10>
Next, a processing flow in the recording / reproducing apparatus 10 will be described with reference to FIGS. In particular, switching processing between the optical disc drive 21 (first operation unit 11) and the memory card drive 22 (second operation unit 12) during content reproduction or recording will be described. In addition, processing when the optical disk 30 is taken out will be described with reference to FIGS.

(Switching process during playback (part 1))
First, referring to FIG. 7 and FIG. 8, when the power supply state to the optical disc drive 21 becomes unsatisfactory (deteriorates), recording / reproduction when switching from the optical disc 30 to recording and / or reproduction control for the memory card 31 is performed. Processing of the device 10 will be described. FIG. 7 is a flowchart showing an example of processing when the content in the optical disc 30 is recorded in the memory card 31. FIG. 8 is a flowchart showing an example of a playback control switching process when the power supply state to the optical disc drive 21 is not good.

  First, the processing from when the optical disc 30 is inserted until the content in the optical disc 30 is recorded on the memory card 31 will be described with reference to FIG.

  When the optical disk 30 is inserted into an optical disk insertion slot (not shown), the loading confirmation unit 41 confirms that the optical disk 30 has been inserted by receiving a detection signal from the sensor of the insertion slot (S21). This is notified to the playback control unit 42. Upon receiving this notification or a user operation via the operation unit 27, the reproduction control unit 42 transmits a disc reproduction start signal indicating that content reproduction on the optical disc 30 is started to the power supply state determination unit 251.

  When receiving the disk reproduction start signal (S22), the power supply state determination unit 251 confirms the power supply state (power supply state) from the external power source 2 to the optical disk drive 21 (S23). As a result, when it is determined that the power supply state is good (YES in S24), the second capacity confirmation unit 53 confirms the capacity in the memory card 31 in response to the notification (S25), and there is a remaining capacity. (YES in S26), the reproduction control unit 42 is notified accordingly.

  Upon receiving the notification, the reproduction control unit 42 reads the content in the optical disc 30 and temporarily stores it in the storage unit 26. When the reading is completed, an end notification is transmitted to the second recording control unit 52. The second recording control unit 52 reads the content stored in the storage unit 26 and records it in the memory card 31 (S27).

  When the content recording to the memory card 31 is completed (S28), the second recording control unit 52 transmits an end notification to the reproduction control unit 42. Upon receiving the end notification, the playback control unit 42 starts playback of the content recorded on the optical disc 30 (S29).

  As a result, the reproduction control unit 42 can record the content in the memory card 31 before reproducing the content in the optical disc 30, so that the optical disc drive 21 cannot be used as shown in FIG. However, the “content reproduction function” can be maintained by using the memory card drive 22.

  On the other hand, when it is determined in S24 that the power supply state is not good (NO in S24), the process shown in FIG. 7 ends. This is because the optical disk drive 21 may not operate normally in this case. Further, when it is determined in S26 that there is no remaining capacity in the memory card 31 (NO in S26), the process is also terminated. This is because the content cannot be recorded in the memory card 31 in this case. If NO in S26, the process may proceed to S29, and the reproduction control unit 42 may reproduce the content in the optical disc 30.

  Note that the processing of S22 and S29 is not necessarily performed. In this case, when the loading confirmation unit 41 confirms the insertion of the optical disc 30 in S21, the fact is transmitted to the power supply state determination unit 251. Also, in S28, when the second recording control unit 52 finishes content recording on the memory card 31, the processing shown in FIG. In this case, even if the content in the optical disc 30 is not reproduced, the content can be recorded in the memory card 31 when the optical disc 30 is inserted.

  Next, processing when the power supply state to the optical disc drive 21 is not good with the optical disc 30 inserted will be described with reference to FIG.

  First, the power supply state determination unit 251 transmits a power supply state deterioration signal to the reproduction state confirmation unit 45 when determining that the power supply state to the optical disc drive 21 is not good. When receiving the power supply state deterioration signal (S31), the reproduction state confirmation unit 45 confirms whether or not the reproduction control unit 42 is reproducing the content in the optical disc 30 (S32). As a result, when it is determined that the playback state is being played back (YES in S33), the playback state confirmation unit 45 instructs the playback control unit 42 to stop playback of the content in the optical disc 30. Upon receiving this instruction, the playback control unit 42 stops the content playback (S34).

  When the playback control unit 42 stops the content playback, the playback control unit 42 transmits a playback stop notification to the power supply control unit 252. When receiving the reproduction stop notification, the power supply control unit 252 stops the power supply from the external power source 2 to the optical disc drive 21 (S35). For example, when the external power source 2 is configured by an apparatus or the like, this stop may be performed by transmitting a power supply stop instruction to the external power source 2 so that the optical disc drive 21 does not accept power supply. In addition, the optical disk drive 21 may be controlled. At this time, the power supply control unit 252 starts power supply from the internal power supply 24 to the memory card drive 22 (S36).

  Next, when the power supply control unit 252 confirms that power supply to the optical disc drive 21 is stopped, a stop completion notification is transmitted to the content presence / absence confirmation unit 54. Upon receiving this stop termination notification, the content presence / absence confirmation unit 54 confirms the content in the memory card 31 (S37). If the content exists (YES in S38), the display control unit (not shown) A user confirmation display is displayed for allowing the user to confirm whether or not to reproduce the content in the memory card 31 (S39). Here, the content exists in the memory card 31 because the processing shown in FIG. 7 is performed.

  Thereafter, the user inputs permission / rejection of content reproduction in the memory card 31 via the operation unit 27. Upon receiving the permission notification, the playback control unit 42 determines whether playback is permitted or not, and when the playback is permitted (YES in S40), plays the content (S41).

  In this way, by recording the content in the optical disc 30 on the memory card 31 by the processing of FIG. 7, even if the power supply state to the optical disc drive 21 is not good, the content is switched to the content playback in the memory card 31. be able to. Therefore, even when the optical disk 30 cannot be reproduced, the “content reproduction function” of the recording / reproducing apparatus 10 is used for a relatively long period of time by using the memory card drive 22 that consumes less power than the optical disk drive 21. Can be maintained. In addition, since the content is recorded in the memory card 31 when the power supply state is good, the processing is particularly effective when a power outage or the like is expected.

  In the case of NO in S33 (when the content of the optical disc 30 is not being played back), in the case of NO in S38, and in the case of NO in S40, the content in the memory card 31 cannot be played back, so the processing of FIG. Ends.

(Alternative process of FIG. 7)
Here, the alternative process of FIG. 7 is demonstrated based on FIG. FIG. 9 is a flowchart showing another example of processing when the content in the optical disc 30 is recorded in the memory card 31. Note that the processing of S42 to S46 shown in FIG. 9 is the same as the processing of S22 to S26 shown in FIG.

  In S46, when the second capacity confirmation unit 53 determines that there is a remaining capacity (YES in S46), the reproduction control unit 42 is notified accordingly. Upon receiving this notification, the reproduction control unit 42 reads and reproduces the content in the optical disc 30 and sequentially stores the content in the storage unit 26. In addition, the reproduction control unit 42 transmits a reproduction start notification to the second recording control unit 52.

  Upon receiving the reproduction start notification, the second recording control unit 52 reads the content sequentially stored in the storage unit 26 and records the content on the memory card 31 (S47). That is, the operation unit control unit 253 differs from the processing of S27 to S29 in FIG. 7 (processing of recording the content of the optical disc 30 on the memory card 31 and starting playback of the content) to the content in the optical disc 30 as a memory card. The content is reproduced while buffering in the area 31.

  Thereby, the content can be recorded on the memory card 31 while the content in the optical disc 30 is played back. For this reason, by performing the process of FIG. 8 after the process of FIG. 9, the “content reproduction function” using the memory card drive 22 can be maintained as described above. In addition, since the content is automatically recorded in the memory card 31 when the power supply state is good, the processing is particularly effective when it is impossible to predict when a power failure or the like occurs.

(Switching process during playback (part 2))
Next, another example of the reproduction control switching process when the power supply state to the optical disc drive 21 is not good will be described. Here, a case will be described in which the content in the optical disc 30 is recorded on the memory card 31 after it is determined that the power supply state is not good. FIG. 10 is a flowchart showing another example of the playback control switching process when the power supply state to the optical disc drive 21 is not good.

  Note that the processing of S51 to S56 and S60 to S62 shown in FIG. 9 is the same as the processing of S31 to S35 and S39 to S41 shown in FIG.

  In S55, when the power supply control unit 252 confirms that the power supply to the optical disc drive 21 is stopped, a stop completion notification is transmitted to the second capacity confirmation unit 53. Upon receiving the notification, the second capacity confirmation unit 53 confirms the capacity in the memory card 31 (S57). This process is the same as S25 shown in FIG. 7, and thereafter, the same process as S26 to S28 shown in FIG. 7 is performed (S58 to S60).

  However, since the power supply to the optical disk drive 21 has already been stopped in S55, in S59, while the reproduction control unit 42 is reading the content from the optical disk 30, the optical disk drive 21 is read from the recording / reproducing apparatus 10 by the inside. Requires power supply. For this reason, in the recording / reproducing apparatus 10 that realizes the processing shown in FIG. 10, the optical disc drive 21 is connected to an internal power source (not shown in FIG. 5), and the power supply control unit 252 Power is supplied from the internal power source to the optical disc drive 21.

  Thereafter, when the content recording to the memory card 31 is completed (S28), the second recording control unit 52 transmits a notification of the completion to the content presence / absence confirmation unit 54. Upon receiving this end notification, the content presence / absence confirmation unit 54 causes a display control unit (not shown) to perform a user confirmation display for allowing the user to confirm whether or not to reproduce the content in the memory card 31 (S60). ).

  As described above, in FIG. 10, when the power supply state to the optical disk drive 21 is not good, recording and reproduction to the memory card 31 are performed in a series of processes. For this reason, as described in “(Switching process at the time of reproduction (part 1))”, since the recording and the reproduction are not performed at different timings, the switching process can be simplified and the recording and reproduction can be performed. The processing burden on the apparatus 10 can be reduced.

(Switching process during recording (part 1))
Next, an example of the recording control switching process when the power supply state to the optical disc drive 21 is not favorable will be described. FIG. 11 is a flowchart showing an example of a switching process when the above-described power supply state becomes unfavorable during content recording on the optical disc 30. FIG. 12 is a diagram illustrating an example of processing when the power supply state is recovered.

  In the following description, it is assumed that the content recorded on the optical disc 30 is broadcast content received via a tuner (not shown) connected to the recording / reproducing apparatus 10. In addition, when receiving the broadcast content, the recording control unit 43 sequentially records the content on the optical disc 30.

  In FIG. 11, first, the power supply state determination unit 251 transmits a power supply state deterioration signal to the recording state confirmation unit 46 when determining that the power supply state to the optical disc drive 21 is not good. When receiving the power supply state deterioration signal (S71), the recording state confirmation unit 46 confirms whether or not the recording control unit 43 has recorded content on the optical disc 30 (S72). As a result, when it is determined that recording is in progress (YES in S73), the recording state confirmation unit 46 instructs the recording control unit 43 to stop content recording on the optical disc 30. Upon receiving this instruction, the recording control unit 43 stops content recording (S74). At this time, the control unit 25 temporarily stores content received thereafter in the storage unit 26.

  When the content control is stopped, the recording control unit 43 transmits a recording stop notification to the power supply control unit 252. Upon receiving this recording stop notification, the power supply control unit 252 stops the power supply from the external power supply 2 to the optical disc drive 21 (S75), and starts the power supply from the internal power supply 24 to the memory card drive 22 ( S76). The stopping method in S75 is as described in S35 shown in FIG.

  Next, when the power supply control unit 252 confirms that the power supply to the optical disc drive 21 is stopped, a stop completion notification is transmitted to the second capacity confirmation unit 53. Upon receiving the notification, the second capacity confirmation unit 53 confirms the capacity in the memory card 31 (S77), and if it is determined that there is a remaining capacity (YES in S78), the second recording control unit 52 is notified accordingly. To do. The second recording control unit 52 reads the content not recorded on the optical disc 30 (broadcast content received after S74 and could not be recorded on the optical disc 30) from the storage unit 26 and records it on the memory card 31 (S79). Then, when the second recording control unit 52 finishes recording the unrecorded content on the memory card 31 (S80), the process of FIG. 11 ends.

  In the above, the received content is temporarily stored in the storage unit 26 functioning as a buffer in S74, and the content is recorded in the memory card 31 in S79. This is because the content recorded on the memory card 31 is recorded without interruption from the continuation of the content recorded on the optical disc 30 when the recording destination of the content is switched from the optical disc 30 to the memory card 31. is there.

  For this reason, it is preferable that the content is temporarily stored in and read from the storage unit 26 so that the content is not interrupted when the recording destination is switched. In other words, after content recording (recording) on the memory card 31 is started, it is preferable that recording is performed only on the memory card 31 and recording on the storage unit 26 is stopped. This is because, in a situation where it is possible to record the content recorded on the optical disc 30 on the memory card 31 without interruption, it is not necessary to perform the processes such as temporary storage and reading. In this case, further power saving can be achieved.

  It should be noted that the timing at which recording to the storage unit 26 is stopped is all the content temporarily stored in the storage unit 26 by the second recording control unit 52 so that a situation in which a part of the content is not recorded on the memory card 31 does not occur. It is preferably after recording to the memory card 31. In this case, for example, when the process of S80 ends, the control unit 25 stops the content storage in the storage unit 26.

  When recording the content temporarily stored in the storage unit 26 to the memory card 31, the second recording control unit 52 stores the content in the storage unit 26 on the memory card 31 until all the content in the storage unit 26 is recorded on the memory card 31. By making the content recording speed faster than the content recording speed on the recording unit 26 by the control unit 25, it is possible to shorten the time until the recording on the memory card 31 is completed.

  As described above, according to the process of FIG. 11, even if the power supply state of the optical disc drive 21 is not good, the content to be received thereafter can be recorded on the memory card 31 instead of the optical disc 30. For this reason, even if the recording to the optical disc 30 is not possible, the “content recording function” of the recording / reproducing apparatus 10 is used for a relatively long period of time by using the memory card drive 22 that consumes less power than the optical disc drive 21. Can be maintained.

  In the case of NO in S73 (when content is not being recorded on the optical disk 30), in the case of NO in S77, since the content cannot be recorded in the memory card 31, the processing in FIG. 11 ends.

  Next, processing after power supply recovery to the optical disc drive 21 will be described with reference to FIG.

  The power supply state determination unit 251 transmits a power supply state good signal to the recording state confirmation unit 46 when determining that the power supply state to the optical disc drive 21 is good. When the recording state confirmation unit 46 receives the power supply state good signal (S81), the recording state confirmation unit 46 confirms whether content recording on the optical disc 30 by the recording control unit 43 is completed (S82). In this case, the recording state confirmation unit 46 determines whether there is a case where the power supply state is not good at the time of use of an electronic program guide (EPG) by the control unit 25, confirmation to the user, and recording of content on the optical disc 30, for example. Whether or not the content recording has been completed is confirmed (S83).

  As a result, when it is determined that the content is incomplete (YES in S83), the recording state confirmation unit 46 notifies the content presence / absence confirmation unit 54 to that effect. Upon receiving this notification, the content presence / absence confirmation unit 54 confirms the content in the memory card 31 (S84), and if the content exists (YES in S85), notifies the capacity confirmation unit 44 to that effect.

  Upon receiving this notification, the capacity confirmation unit 44 confirms the capacity of the content stored in the storage unit 26 (S86), and confirms the remaining capacity in the optical disc 30 (S87). When the remaining capacity in the optical disc 30 is larger than the content capacity, the capacity confirmation unit 44 determines that “remaining capacity exists” (YES in S88), and transmits the determination result to the recording control unit 43.

  In response to the determination result, the recording control unit 43 records unrecorded content on the optical disc 30 (S89). When the recording is completed (S90), a recording completion notification is transmitted to the second recording control unit 52. Upon receiving the recording completion notification, the second recording control unit 52 deletes the content in the memory card 31 (the content recorded on the optical disc 30 in S89) (S91).

  If NO in S83 and NO in S85, there is no unrecorded content on the optical disc 30, and if NO in S88 (“no remaining capacity”), content cannot be recorded on the optical disc 30. The process in FIG. 12 ends.

  As described above, according to the processing of FIG. 11, even when the power supply state to the optical disc drive 21 is not good during content recording on the optical disc 30, all the content can be recorded on the memory card 31. That is, even if the state is not good, the “content recording function” of the recording / reproducing apparatus 10 can be maintained for a relatively long period of time by using the memory card drive 22 that consumes less power than the optical disk drive 21. .

  In addition, according to the process of FIG. 12, since all the contents can be recorded on the optical disc 30 after the power supply state is recovered, the recording leakage to the optical disc 30 due to the poor power supply state is prevented. be able to. That is, even if the state is not good, all contents can be recorded on the optical disc 30 as in the case where the state is always good. Further, even when the state is not good, unified management with the optical disc 30 becomes possible as the state is recovered.

(Processing during take-out (part 1))
Next, a process at the time of taking out the optical disk 30 will be described. FIG. 13 is a flowchart showing an example of processing when the optical disc 30 is taken out while the content of the optical disc 30 is being reproduced. FIG. 14 is a flowchart showing an example of processing when the optical disc 30 is taken out during content recording on the optical disc 30.

  In FIG. 13, first, when the loading confirmation unit 41 receives an instruction to eject the optical disc 30 via the operation unit 27, the loading confirmation unit 41 transmits a removal signal indicating that to the reproduction state confirmation unit 45. When receiving the take-out signal (S101), the reproduction state confirmation unit 45 confirms whether or not the reproduction control unit 42 is reproducing the content in the optical disc 30 (S102). Thereafter, the processing of S33 and S34 shown in FIG. 8 is performed (S103 and S104). After confirming that the content reproduction on the optical disc 30 is stopped, the reproduction control unit 42 transmits a reproduction stop notification to the content presence / absence confirmation unit 54 and the power supply control unit 252. Upon receiving this reproduction stop notification, the power supply control unit 252 starts power supply to the memory card drive 22 (S105), as in S36 of FIG.

  Further, when receiving the reproduction stop notification, the content presence / absence confirmation unit 54 confirms the content in the memory card 31 (S106), and if there is content (YES in S107), the second recording control It transmits to the part 52. Upon receiving this notification, the second recording control unit 52 starts erasing the contents existing in the memory card 31 (S108). When the erasing is finished (S109), the second recording control unit 52 sends an erasure end notification to the optical disc drive control unit 4. Send. The optical disc drive control unit 4 receives the erase end notification and ejects the optical disc 30 (S110).

  If NO in S103, the process proceeds to S105. If NO in S107, the contents in the memory card 31 cannot be erased, and the process in FIG. 13 ends.

  Next, in FIG. 14, when the loading confirmation unit 41 receives an instruction to eject the optical disc 30 via the operation unit 27, the loading confirmation unit 41 transmits a removal signal indicating that to the recording state confirmation unit 46. When receiving the take-out signal (S111), the recording state confirmation unit 46 confirms whether or not the recording control unit 43 has recorded content on the optical disc 30 (S112). Thereafter, the processes of S73 and S74 shown in FIG. 11 are performed (S113 and S114). After confirming that content recording on the optical disc 30 is stopped, the recording control unit 43 transmits a recording stop notification to the content presence / absence confirmation unit 54 and the power supply control unit 252. Upon receiving this recording stop notification, the power supply control unit 252 starts power supply to the memory card drive 22 as in S76 of FIG. 11 (S115).

  Further, when receiving the recording stop notification, the content presence / absence confirmation unit 54 confirms the content in the memory card 31 (S116). Then, the process of S85-S91 shown in FIG. 12 is performed (S117-S123). When the erasure of the content existing in the memory card 31 is completed (S124), the second recording control unit 52 transmits an erasure completion notification to the optical disc drive control unit 4. The optical disc drive control unit 4 receives the erase end notification and ejects the optical disc 30 (S125).

  As described above, in the processing of FIGS. 13 and 14, since the content in the memory card 31 is recorded on the optical disc 30 when the optical disc 30 is taken out, the content is not divided and recorded on another optical disc. Further, since the contents in the memory card 31 are erased when the optical disk 30 is taken out, even if the contents are recorded on the memory card 31, it is possible to prevent a situation in which the contents are leaked, thereby protecting the contents. Can be planned. Further, by temporarily recording data on the memory card 31, the capacity of the memory card 31 can be reduced.

(Switching process when taking out (part 2))
Next, further processing at the time of taking out the optical disk 30 will be described with reference to FIG. FIG. 15 is a flowchart showing another example of processing when the optical disc 30 is taken out while the content of the optical disc 30 is being reproduced.

  First, when receiving an instruction to remove the optical disk 30 via the operation unit 27, the loading confirmation unit 41 transmits a removal signal indicating that to the reproduction state confirmation unit 45 or the recording state confirmation unit 46. Thereafter, the processing of S101 to S107 shown in FIG. 13 or the processing of S111 to S117 shown in FIG. 14 is performed (S131 to S137).

  When the content exists (YES in S137), the content presence / absence confirmation unit 54 transmits the fact to the reproduction control unit 42. Upon receiving this notification, the playback control unit 42 reads the disc identification information recorded in the management area (for example, BCA (Burst Cutting Area)) of the optical disc 30 and confirms the disc type of the optical disc 30 (S138). As a result, when the reproduction control unit 42 determines that the disc type is a recording type (YES in S139), the reproduction control unit 42 transmits the determination result to the capacity confirmation unit 44. The disc identification information includes the type of recording layer of the optical disc 30 (reproduction-only type, recording type (write-once type, rewritable type)) and the like.

  Upon receiving this determination result, the capacity confirmation unit 44 confirms the capacity of the content stored in the storage unit 26 (S140), and confirms the remaining capacity in the optical disc 30 (S141). Then, the process of S120-S125 shown in FIG. 14 is performed (S142-S147).

  As described above, according to the processing of FIG. 15, after confirming that the disc type of the optical disc 30 is the recording type when the optical disc 30 is taken out, the recording of the unrecorded content on the optical disc 30 and the recording in the memory card 31 are performed. Erase content. For this reason, in addition to the effects produced by the processes of FIGS. 13 and 14, by identifying the disk type of the optical disk 30, it is possible to determine whether the optical disk 30 was performing a reproducing or recording operation immediately before. Therefore, it is possible to identify only the case where the recording operation was performed immediately before, and to reliably record the unrecorded content on the optical disc 30.

  In the above description, when the disc is ejected, the content in the memory card 31 is finally automatically erased. However, the present invention is not limited to this. After the disc is ejected, the contents in the memory card 31 may be erased by a user operation, or may be automatically erased when the remaining capacity of the memory card 31 runs out.
