Here, the manager electronic key 30 is not limited to the usage time of the device 50, so a memory for storing the usage time is unnecessary.

The present invention is a device for limiting the use time of the device, as described above. In other words, the term "device" herein means a broad term including all devices that operate by receiving a TV, a computer, a home appliance, and other power sources.

The following describes a control process of the time limit device of the device according to the present invention by using a TV as an example.

First, the first embodiment stores the use time in the electronic key for the child, the power is supplied to the TV only for the stored use time, and the use time of the electronic key for the child is deducted as much as the power supply time to the TV. It is done.

As illustrated in FIG. 6, when the power is applied to the usage time limiting device, the control unit 100 performs a normal initialization process (S10).

When the initialization process (S10) is completed, the control unit 100 performs a key insertion determination process to determine whether the electronic key (20, 30) is inserted into the key insertion unit 70 (S11).

If it is determined that the electronic keys 20 and 30 are not inserted into the key insertion unit 70 in the key insertion determination process (S11), the control unit 100 performs a clock mode (S20). In other words, if the current time is displayed and the alarm time is reset through the key input unit 13, the alarm function is performed based on the newly set alarm time.

On the contrary, if it is determined that the electronic keys 20 and 30 are inserted in the key insertion determination process S11, the control unit 100 reads the unique code value from the electronic keys 20 and 30 and the user electronic key 20 or less. The electronic key identification process for determining whether the electronic key for the child) or the electronic key for the administrator (hereinafter referred to as the electronic key for the parent) is performed (S12).

If it is determined that the electronic key 20 for the child in the electronic key identification process (S12), the control unit 100 performs a child use mode (S30). That is, the control unit 100 reads the pre-stored use time from the memory 22 of the child electronic key 30, and stores the pre-stored use time in the main memory 81 of the main device and powers the TV. A power on process is performed to control the electronic switch 60 as much as possible. In addition, the power-on time is counted by the controller 100 according to the power-on, and the controller 100 controls the memory 22 through communication with the child electronic key 20 so that the pre-stored use time is subtracted by the counted time. The use time stored in advance is updated at a predetermined cycle (S31).

Subsequently, the controller 100 compares the counted time according to the power supply with the usage time read from the memory 22 of the first child electronic key 20 and stored on the main memory 81 of the main device, and counted. In operation S32, a time-lapse determination process for determining whether the time has elapsed has been performed.

When the time counted in the use time elapsed determination process (S32) has elapsed a predetermined time, the control unit 100 controls the electronic switch 60 to cut off the power supply to the TV 50, the power OFF process Perform (S33).

As a result, the device can limit children's TV viewing time on behalf of their parents.

On the contrary, when the time counted in the use time elapsed determination process (S32) does not reach the preset time, the control unit 100 performs process S31 and the power supply of the electronic switch 60 is continuously performed. Maintain the status quo.

If the counted time does not reach the preset time and is removed from the child electronic key 20 key insertion unit 70, the controller 100 deletes the usage time data stored in the main memory 81. The electronic switch 60 is controlled to cut off the power supply to the TV 50.

In addition, when the electronic key 20 for a child is reinserted into the key insertion unit 70, the memory 22 of the electronic key for the child is deducted from the time of use of the previous TV, and thus, the aforementioned S11, S12, S30, and S31. According to the S32 process, the TV can be used only for the remaining time of the use time (the time saved by the parent) previously stored in the initial memory 22.

On the other hand, if it is determined in the electronic key identification process (S12) as the parent electronic key 30, the control unit performs a parent use mode (S40).

In this case, when the electronic key 30 for the parent is removed from the key insertion unit 70 within a predetermined time (about 30 seconds), a key removal determination process for determining this is performed (S41).

If it is determined that the electronic key 30 for the parent is removed in the key removal determination process (S41), the control unit 100 performs the usage time setting mode (S42).

If the insertion of the electronic key 20 for the child is detected from the key insertion unit 70 in the use time setting mode (S42) (S43), when the setting of the use time is input through the key input unit 13, the control unit 100 The store performs the use time storing process of storing the input use time on the memory 22 of the child electronic key 20 (S44).

As a result, the use time can be easily stored in the electronic key for the child with only one key insertion unit.

Subsequently, when the parent electronic key 30 is reinserted into the key insertion unit 70, the controller 100 performs the parent use mode S40, and when there is no reinsertion of the parent electronic key 30. It ends.

If it is determined that the electronic key 30 for parents is continuously detected in the key removal determination process (S41) and a predetermined time (about a few tens of seconds or so) has elapsed (S51), the controller 100 supplies power to the TV 50. A power-on process is performed to control the electronic switch 60 to be applied (S52).

Subsequently, the controller 100 determines whether the electronic key 39 for parents is removed through the key insertion unit 70 (S53), and when it is determined that the electronic key 30 for parents is removed, the TV 50. In order to cut off the power supply to the power supply (OFF) process to control the electronic switch 60 (S54), and if the parent electronic key 30 is continuously detected from the key insertion unit 70 TV ( The electronic switch 60 is maintained in the present state so that power is continuously applied to 50).

The second embodiment is characterized in that a time zone for using (viewing) a TV is stored in a child electronic key and power is supplied to the TV only during the stored time zone. For example, when the children's broadcasting time zone is approximately PM 17:00 to PM 19:00, the time zone is stored in the electronic key for the child, and the TV can be used (viewing) at that time every day without a separate operation.

As shown in FIG. 7, the second embodiment sequentially performs steps S10, S11, S12, and S30 (S10, S11, S12, and S20 are the same as described in FIG. 6, and thus will be omitted).

If it is determined that the electronic key 20 for the child in the electronic key identification process (S12), the control unit 100 performs a child use mode (S30).

That is, the controller 100 compares the current time and the time zone stored in the memory 22 of the electronic key for the child, and performs a usage time determination process to determine whether the current time is included in the pre-stored time zone. (S31 ').

If the current time is included in the time zone stored on the memory 22 of the child's electronic key in the use time determination process, the power ON process is performed to control the electronic switch 60 to supply power to the TV ( S32 ').

On the contrary, if the current time is not included in the time zone stored in the memory 22 of the child electronic key in the process of determining the use time, the control unit 100 switches the electronic switch 60 to cut off the power supply to the TV 50. A power off process is performed (S33 '). As a result, the device can limit children's TV viewing time on behalf of their parents.

On the other hand, if it is determined in the electronic key identification process (S12) as the parent electronic key 30, the control unit 100 performs a parent use mode (S40).

In this case, when the electronic key 30 for the parent is removed from the key insertion unit 70 within a predetermined time (about 30 seconds), a key removal determination process for determining this is performed (S41).

If it is determined that the electronic key 30 for the parent is removed in the key removal determination process (S41), the control unit 100 performs the use time zone setting mode (S42 ').

In the use time setting mode (S42 '), the insertion of the electronic key 20 for the child is detected from the key insertion unit 70 (S43'), and the use time zone (for example, from 5 pm to 7 pm through the key input unit 13). When the time is input, when the setting of the start time 1700 and the end time 1900 is input through the key input unit, the control unit 100 inputs the input time zone of the memory of the electronic key 20 for the child (20). 22) perform a use time storage process for storing on (S44 ').

As a result, the use time can be easily stored in the electronic key for the child with only one key insertion unit.

Thereafter, S51, S52, S53, and S54 described above with reference to FIG. 6 are performed selectively or sequentially.

Here, in describing the embodiment according to the present invention, although the TV as an example, it can of course be applied to all devices to limit the use time.

As described in detail above, according to the present invention, by setting the use time or use time zone on the user's electronic key and allowing the device to be used only for the set time or time zone, the use time of the device can be limited even in the absence of the device administrator. There is an effect.

In addition, when applied to a TV or a computer, enter the use time or time zone in advance for the child's electronic key, and the TV or computer to operate only in the input time or time zone, so that children can watch TV indiscriminately Restrict computer use. As a result, there is an effect that children can develop a habit of using leisure time appropriately.
