  In recent years, in a karaoke system, for example, in order to improve convenience when performing karaoke by operating one karaoke device in a karaoke room (room where karaoke is performed) and the karaoke device from a remote location in the karaoke room, Multiple remote control terminals are installed, and services that use karaoke rooms on an hourly basis have become widespread. In general, in a fee system using a karaoke room, a fee obtained by multiplying the usage fee per unit time by the usage time is often charged.

  By the way, for example, when the remote control terminal is communicating with the karaoke apparatus, the output voltage level and the charge amount of the secondary battery built in the remote control terminal are reduced, and the remote control terminal can be used to input a reservation song for karaoke performance or to confirm the reservation song. Service using is interrupted. Therefore, the output voltage level and charge amount of the secondary battery built in each of the plurality of remote control terminals are measured, the time that the remote control terminal can be used is calculated according to the measured output voltage level and charge amount, and the calculated remote control It is conceivable that the karaoke room can be used so that the service using the remote control terminal is not interrupted by matching the available time of the karaoke room with the shortest available time of each terminal.

  However, in the karaoke system as described above, the karaoke room usage time is set according to the remote control terminal with the shortest available time. As a karaoke store, there is a risk that the fee revenue will be reduced.

  Also, if you wait for the secondary battery to be fully charged until the secondary battery is fully charged, you can set the maximum available time after it is fully charged, but during that time you cannot use the karaoke room, Convenience worsens. Even in this case, the fee income as a karaoke store cannot be obtained while it cannot be used. The user will know whether or not the karaoke room can be used after visiting the karaoke store, and the possibility of dissatisfaction increases. Therefore, it is conceivable to stop using the secondary battery of the remote control terminal and use it with a commercial power supply, but since the power cable is connected to the remote control terminal and the operability of the remote control terminal is impaired, karaoke is performed. When convenience becomes worse. Even if it does in this way, possibility that a user will be dissatisfied becomes high, and possibility that a fee income will also be affected by a user's dissatisfaction becomes high.

  The present invention has been made in view of such a problem, and an object of the present invention is to output secondary batteries built in each remote control terminal in a karaoke system in which a karaoke apparatus is operated by a plurality of remote control terminals. The object is to provide a technique for preventing a decrease in the use time of a karaoke room even when the voltage level and the amount of charge are small, and to maintain the convenience of a remote control terminal for karaoke room users.

  The karaoke system of the present invention, which has been made to solve the above-mentioned problems, divides the supply of the power supply voltage of the remote control terminal into a user interface unit consisting of operation means and display means, and other main body parts, While supplying power to all the main body parts of the remote control terminal so as to maintain the state where the power consumption is minimized, the user interface part is supplied to only one of the plurality of remote control terminals. When the power supply voltage is supplied and the output voltage value of the secondary battery of that one remote control terminal is lower than the predetermined voltage value or the charge amount is lower than the predetermined value, before the operation of the remote control terminal itself stops, It is characterized by switching to another remote control terminal.

  Generally, a remote control terminal for karaoke, like a portable computer (laptop computer), consumes less power, such as an LCD backlight or a plasma display, which constitutes a part of display means when no input operation is performed. By turning off many devices, the power consumption of the secondary battery of the remote control is suppressed, and the operation (power management) is performed so as to keep the state where the power consumption is minimized (stationary state). In such a state, the degree of power consumption of the secondary battery decreases. However, if the user does not aim at the song input operation but performs an input operation such as pressing one key by mistake, for example, the control means of the remote control terminal determines that the input operation has been performed and the power is By releasing the management, a normal operation state is obtained for a certain period. During this time, the LCD backlight is also turned on, so that the secondary battery consumes power rapidly even though the remote control terminal is not used. For this reason, when the use is started, the usable period of the remote control terminal is shortened, and if charging is in progress, the time until full charge is lengthened. In other words, even if a terminal is installed with a remote controller that is not being used, for example, power is consumed when a drunk user touches unconsciously. Therefore, only the remote control terminal in the karaoke room where the karaoke device does not affect the progress of the karaoke service (for example, karaoke song performance) by the karaoke device is kept stationary until immediately before the karaoke service is affected, thereby affecting the karaoke service. Only the remote control terminal to be operated can be operated from the user.

  Immediately before the operable remote control terminal affects the karaoke service, the stationary state is canceled in a state where there is no sense of incongruity with the remote control terminal used by the user until just before that. That is, power is supplied to the user interface unit to enable input operation, and the LCD backlight is also turned on in a display state immediately before affecting the karaoke service. As described above, the present invention is characterized in that a decrease in the use time of the karaoke room is prevented, and an effect that does not make the user feel dissatisfied by maintaining the progress of the karaoke service is provided.

  Specifically, in the above karaoke system, first, the output voltage request information transmitting means of the karaoke apparatus outputs the output voltage request information for requesting each of the plurality of remote control terminals to transmit the output voltage related information. The apparatus side transmission means is controlled to transmit. Further, the karaoke device selection means determines whether the first karaoke device side receiving means has received the output voltage related information from each of the plurality of remote control terminals, and outputs the output voltage related information from all of the plurality of remote control terminals. When it is determined that it has been received, the remote control terminal identification information of each of the plurality of remote control terminals is sequentially selected from the output voltage related information of each of the plurality of remote control terminals stored in the karaoke device side storage means. Power supply request information for requesting the remote control terminal identified by the remote control terminal identification information selected by the selection means to supply the power supply voltage to the display means and the operation means. The first karaoke device side transmission means is controlled to transmit, and the power supply voltage is cut to all display means and operation means to all remote control terminals identified by the remote control terminal identification information not selected by the selection means. The power-off request information for requesting is transmitted by controlling the karaoke apparatus side transmission means. Further, when the remote control terminal side receiving means receives the power supply request information from the karaoke device, the remote control terminal switching control means controls the switching means to supply the display means and the operating means with the power supply voltage, When the remote control terminal side receiving means receives the power cut request information from the karaoke apparatus, the switching means is controlled to cause the display means and the operating means to cut the power supply voltage. In addition, when the remote control side control means detects that the voltage value of the output voltage of the power supply unit is equal to or less than a predetermined voltage value, the remote control terminal identification is performed from the output voltage related information stored in the remote control terminal side storage means. The remote control terminal side reads out the information and associates the output voltage shortage information indicating that the voltage value of the output voltage of the power supply unit detected by the remote control terminal identification and detection means is not more than a predetermined voltage value as output voltage shortage related information The transmitting means is controlled to transmit to the karaoke apparatus. When the karaoke device side control means receives the remote control terminal identification information and the output voltage shortage related information from the remote control terminal identified by the remote control terminal identification information selected by the selection means by the first karaoke device side reception means. The selection means is controlled to select the next remote control terminal identification information.

  The detection means of the remote control terminal does not necessarily detect the voltage value of the output voltage of the power supply unit. The current consumption may be detected by the following publicly known technique (see Japanese Patent Laid-Open No. 05-3633), the result of conversion into voltage using Ohm's law from the internal resistance of the circuit wiring measured in advance, Japanese Patent Laid-Open No. 05-191932) may be detected to detect the shortage of the output voltage from the calculation result of the subtraction of the charging time and the usage time.

  According to the karaoke system of the present invention thus configured, the power supply voltage is supplied only to the display means and the operation means of the remote control terminal selected by the selection means, and the display means of all the remote control terminals not selected by the selection means And the power supply voltage is cut off to the operating means. Further, when the detection means of the remote control terminal selected by the selection means detects that the voltage value of the output voltage of the power supply unit is equal to or lower than the predetermined voltage value, the output voltage shortage related information is transmitted to the karaoke apparatus. Then, the selection means selects the next remote control terminal. Therefore, in a karaoke system in which a karaoke apparatus is operated by a plurality of remote control terminals, the power supply voltage is supplied only to the display means and operation means of the selected remote control terminal among the plurality of remote control terminals, so that it can be used as a karaoke room. At the same time, since the power supply voltage is cut off for the display means and operation means of the remaining remote control terminals, the power consumption of the remaining remote control terminals can be reduced. In addition, when the karaoke system is provided with a dedicated stand for charging the power supply unit of the remote control terminal, the power supply units of the remaining remote control terminals can be charged. Furthermore, since the next remote control terminal is selected when the voltage value of the output voltage of the power supply unit of the selected remote control terminal is equal to or lower than the predetermined voltage value, it is possible to prevent a decrease in usage time as a karaoke room.

  Also, the remote control terminal may be turned on sequentially from the remote control terminal with a large amount of charge. Specifically, as described in claim 2, the selecting means outputs the output voltage indicated by the output voltage information of each of the plurality of remote control terminals from the output voltage related information of each of the plurality of remote control terminals stored in the karaoke device-side storage means. The remote control terminal identification information associated with the output voltage information with the largest output voltage voltage to the remote control terminal identification information associated with the output voltage information with the smallest output voltage value are sequentially compared. It is good to choose.

  According to the karaoke system configured as described above, the remote control terminal converts the remote control terminal identification information related to the output voltage information having the largest output voltage value to the output voltage information having the smallest output voltage value. The related remote control terminal identification information is sequentially selected. That is, by turning on the power sequentially from a remote control terminal having a large amount of charge (the terminal voltage is highest in voltage control), an effect of not reducing the convenience of the remote control terminal by the user can be obtained. For example, when the scheduled use time is 70 minutes, the available time of the remote control terminal A is 60 minutes, the remote control terminal B is 30 minutes, and the remote control terminal C is 15 minutes, it is used from the remote control terminal A with the largest amount of charge. If possible, only one bridge is required. However, if the bridge is performed in the order of B, C, and A without considering the order, for example, the number of bridges is two times, and the convenience for the user is lower than when the order is not considered. That is, if the number of times that the available remote control terminal is replaced (the number of times of bridging) is small, an effect of not reducing convenience is obtained.

  By the way, in general, a plurality of karaoke rooms are provided in a karaoke store. For example, each karaoke room is provided with one karaoke device and a plurality of remote control terminals for operating the karaoke device. A management device for managing a plurality of installed karaoke devices is installed at the reception of the karaoke store. Then, a user who intends to use the karaoke service in such a karaoke store makes an application for using the karaoke room, for example, by receiving a karaoke store that manages the karaoke room. Then, the clerk of the karaoke store selects a karaoke room in which the karaoke device and the plurality of remote control terminals can be used from a plurality of Karao rooms provided in the karaoke store, for example, and guides the user to the selected karaoke room. . Therefore, when the clerk selects a karaoke room in which the karaoke device and a plurality of remote control terminals can be used, the karaoke device and the plurality of remote control terminals can be used from the karaoke device installed in the karaoke room. It is good to inform the management device whether or not.

Specifically, as described in claim 1 , karaoke device identification information for identifying the use time information received by the management device side accepting means and the karaoke device identification information by the management device use availability request information transmitting means. And the availability request information for requesting to transmit availability information associated with either the availability information indicating availability or the availability information indicating unusability, the management device side transmission means Control to transmit to the plurality of karaoke devices. Further, the calculation means of the karaoke device extracts the output voltage information from each of the output voltage related information stored in the karaoke device-side storage means, and the karaoke device can be used based on the output voltage value indicated by each of the extracted output voltage information Calculate time. Further, the karaoke device side control means, when the second karaoke device side receiving means receives the usage time information and the availability request information from the management device, the available time and usage time information calculated by the calculation means. Is compared with the usage time indicated by the karaoke device, it is determined whether or not the calculated available time is greater than the usage time, and if it is determined that the calculated available time is equal to or greater than the usage time, the karaoke device side Management device for controlling the second karaoke device side transmission means including the karaoke device identification information and the usable information stored in the storage means and the usable time information indicating the usable time calculated as the usable time information On the other hand, if it is determined that the calculated available time is shorter than the usage time, the karaoke device identification information and the interest stored in the karaoke device-side storage means Impossible information by controlling the second karaoke apparatus side transmission unit is transmitted to the management apparatus. Whether or not the karaoke device selection unit of the management device has received the usable information when the management device receiving unit receives either the usable information or the unusable information from each of the plurality of karaoke devices. If it is determined that the available information has been received, the available time indicated by each of the received available time information including all of the received available information is compared, and the smallest available time The received karaoke device identification information is selected together with one usable time information indicating.

  According to the karaoke system configured as described above, the karaoke device calculates the available time based on the output voltage values of the power supply units of the plurality of remote control terminals, and the calculated available time is calculated from the management device. If it is equal to or larger than the usage time requested by the transmitted user, the available information and the available time information are transmitted to the management apparatus. On the other hand, if the calculated available time is shorter than the usage time requested by the user transmitted from the management device, the unavailable information is transmitted to the management device. The management device compares the available times indicated by the received available time information, and selects the karaoke device having the smallest available time. In other words, a karaoke apparatus having an available time that is longer than the usage time requested by the user but closest to the usage time requested by the user is selected. As an example, the usage time requested by the user is, for example, 1 hour, and there are, for example, two karaoke devices that have an available time exceeding 1 hour, and the available time that each karaoke device has is, for example, 1.5. When the time is 2.2 hours, a karaoke device having an available time of 1.5 hours is selected. That is, when the use time requested by the next user is, for example, 2 hours, the karaoke apparatus having the available time of 2.2 hours can be used. In addition, when the karaoke apparatus which has an available time of 2.2 hours is selected for the previous user, the next user cannot use the karaoke apparatus. Therefore, by selecting a karaoke device having an available time closest to the usage time requested by the user, the number of karaoke devices that can handle the next user can be increased.

  Therefore, if the available time of the remote control terminal is the same as or longer than the use time for the user to use the karaoke room, it is assumed that the karaoke device and the plurality of remote control terminals can be used, and each karaoke device is sent to the management device. I can inform you. Further, if the calculated available time of the remote control terminal is shorter than the use time of the user trying to use the karaoke room, the karaoke device and the plurality of remote control terminals are not in a usable state, and the management device is notified from each karaoke device. be able to. In addition, when there are a plurality of karaoke devices having usable times larger than the usage time requested by the user, the karaoke device having the available time closest to the usage time requested by the user is selected. Can increase the number of karaoke devices.

  Also, in a karaoke system that authenticates a user and permits login to the management device, when the output voltage value of the selected remote control terminal falls below a predetermined voltage value and the next remote control terminal is selected, the user is logged in The identification information regarding the registered user may be transferred to the selected remote control terminal.

Specifically, as described in claim 3 , the authentication unit of the management device indicates a registered user who is permitted to log in to the management device, and the management device-side reception unit transmits the user from the karaoke device. When authentication request information including identification information and password information is received, authentication is performed using the authentication request information, and the authenticated registered user is permitted to log in to the management apparatus. In addition, the karaoke device display availability request information transmission means stores the identification information related to the registered user stored in the karaoke device side storage means to the remote control terminal identified by the remote control terminal identification information selected by the selection means and the identification related to the registered user in the display means. Display request information for requesting to display information is transmitted by controlling the first karaoke device side transmission means, and all the remote control terminals identified by the remote control terminal identification information not selected by the selection means The non-display request information for requesting not to display the identification information relating to the registered user on the display means is controlled by the karaoke apparatus side transmission means and transmitted. Furthermore, when the remote control terminal side receiving means receives the identification information and display request information related to the registered user from the karaoke device, the display control means of the remote control terminal controls the display means to display the identification information related to the registered user, On the other hand, when the remote control terminal side receiving means receives the non-display request information, the display means is controlled so that the identification information relating to the registered user is not displayed.

  According to the karaoke system configured as described above, the display control unit of the remote control terminal selected by the selection unit controls the display unit to display the identification information regarding the registered user, and all the items not selected by the selection unit are selected. The display control means of the remote control terminal does not display the identification information related to the registered user by controlling the display means. Therefore, in a karaoke system that authenticates the user and permits login to the management device, the output voltage value of the selected remote control terminal is equal to or lower than the predetermined voltage value, and the login is performed when the next remote control terminal is selected. The identification information relating to the registered user can also be transferred to the selected remote control terminal. In addition, when the next remote control terminal is selected, the identification information regarding the registered user who is logged in is also automatically transferred to the selected remote control terminal. There is no need to log in.

Moreover, it is good to display the identification information of the room in which the karaoke apparatus selected by the karaoke apparatus selection means in the management apparatus side is installed. Specifically, as described in claim 4 , the management device further includes room identification information for identifying a room in which each of the plurality of karaoke devices is installed, and a karaoke of the karaoke device installed in the room. Management device storage means for associating and storing device identification information, management device side display means capable of displaying various types of information, and management device side display means for displaying room identification information related to karaoke device identification information selected by the karaoke device selection means It is preferable to provide management device side display control means for controlling and displaying the above.

  According to the karaoke system configured in this way, the total available time of the remote control terminal is larger than the scheduled use time of the user, and the room of the closest time can be displayed on the display means of the management device. Since the manager can provide the karaoke room user with a room that does not deteriorate the convenience of performing karaoke, the fee income of the karaoke store described below may not be impaired. For example, in a karaoke store, the available time of room D at a certain point in time is 2 hours, room E is 30 minutes, room F is 15 minutes, and the usage fee is 10 yen / 1 minute. If a room is selected and displayed on the basis of the above algorithm, the user G is guided to the room E. Immediately after that, even if a user H who is scheduled to use for 1 hour visits the store, it is possible to guide to the room D, so both the user G and the user H can use the karaoke room. The effect of maintaining the convenience when performing the operation is obtained. When the usage charges obtained from the user G and the user H are calculated one hour later, they are 200 yen, 600 yen, and a total of 800 yen, respectively. However, if the user G is guided to the room D without using the above algorithm, the user H who visits the store immediately after that cannot use the karaoke service at the store, and thus the convenience of the user G to perform karaoke is impaired. The user G is likely to move to another store. Therefore, since the usage time of the user G is 20 minutes, there is a high possibility that the fee income that the karaoke shop obtains after one hour is only 200 yen. In other words, if the total available time of the remote control terminal is larger than the scheduled usage time of the user and the closest room is displayed on the display means of the management device, the scheduled usage time of the user Can be used with less room, and the convenience of performing karaoke for each user can be maintained, and the karaoke store's fee revenue can be maintained. There is sex.

(H) Detected voltage-related data during charging The detected voltage-related data during charging is data that associates the charging current value of the rechargeable battery 70 detected by the detecting unit 69, the terminal voltage value, and the charging state flag determined by the control unit 52. It is. As shown in FIG. 5 (b), the detected voltage-related data during charging includes the numerical values “1 to n”, the charging current values (J1 to Jn), the terminal voltage of the remote control terminal numbers (1 to n) of the remote control terminal 5. The values (K1 to Kn) and the charge state flags (L1 to Ln) are associated with each other and stored in the charging detected voltage related data memory area 71. For example, the value “1” of the remote control terminal number (1) of the remote control terminal 5, the charging current value (J1), the terminal voltage value (K1), and the charging state flag (L1) are associated with each other to detect the charging voltage. It is stored in the related data memory area 71 (1).

It is. As shown in FIG. 5C, the detected voltage-related data during discharge includes numerical values “1 to n”, charging current values (P1 to Pn), terminal voltages of the remote control terminal numbers (1 to n) of the remote control terminal 5. The values (Q1 to Qn) and the discharge state flags (R1 to Rn) are associated and stored in the discharge detected voltage related data memory area 72. For example, the numerical value “1” of the remote control terminal number (1) of the remote control terminal 5, the charging current value (P1), the terminal voltage value (Q1), and the discharging state flag (R1) are associated with each other and the detected voltage during discharging. It is stored in the related data memory area 72 (1).

  Next, a configuration for detecting the output voltage of the rechargeable battery 70 and a configuration for supplying a power supply voltage to the operation unit 60 and the display unit 58 will be described. FIG. 2 is a block diagram illustrating a configuration for detecting the output voltage of the rechargeable battery 70 and a configuration for supplying a power supply voltage to the operation unit 60 and the display unit 58.

  First, the configuration for detecting the output voltage of the rechargeable battery 70 includes a rechargeable battery 70, a detection unit 69, and a control unit 52, as shown in FIG. In addition, the control unit 52 includes an A / D conversion unit 52a and a charge amount measurement unit 52b. The detection unit 69 detects the charging current value and the terminal voltage value of the rechargeable battery 70 as analog signals and outputs them to the control unit 12. The analog-type charging current value and terminal voltage value signal are converted into a digital charging current value and terminal voltage value signal by the A / D conversion unit 52a of the control unit 52 and output to the charge amount measuring unit 52b. To do. The charge amount measuring unit 52b outputs a charge state flag and a discharge state flag based on a digital charge current value and a terminal voltage value signal. For example, when the remote control terminal 5 is installed in the cradle 6 and the rechargeable battery 70 is charged from the power supply unit of the cradle 6, the charge amount measuring unit 52b is charged when the signal of the terminal voltage value indicates 4V. When the state flag is determined as a numerical value “0” and the terminal voltage value signal indicates 4.4V, the charging state flag is determined as a numerical value “1” and the terminal voltage value signal indicates 4.6V. If the terminal voltage value signal is 4.8V, the charging state flag is determined to be a numerical value "3", and the terminal voltage value signal is 4. When 8 V or more is indicated, the charging state flag is determined as a numerical value “4”. That is, the larger value of the charge state flag indicates that the amount of charge is larger than the smaller value. On the other hand, for example, when the remote control terminal 5 is detached from the cradle 6 and the rechargeable battery 70 is not charged from the power supply unit of the cradle 6, the charge amount measurement unit 52b has a terminal voltage value signal of 4.2V to 4.8V. When the terminal voltage value is 4.2V or less, the numerical value “1” is determined as the discharge state flag. That is, the larger value of the discharge state flag indicates that the amount of charge is larger than the smaller value. The control unit 52 is configured to be able to detect a charging current when the remote control terminal 5 is installed in the cradle 6 and the rechargeable battery 70 is charged from the power supply unit of the cradle 6.

  Next, the configuration for supplying the power supply voltage to the operation unit 60 and the display unit 58 includes a control unit 52, an operation unit 60, and a display unit 58, as shown in FIG. Further, the control unit 52 has a configuration (not shown) for supplying or disconnecting the secondary power to the operation unit 60 and the display unit 58. That is, the control unit 52 can control whether the secondary power is supplied to the operation unit 60 and the display unit 58 or is disconnected.

  The operation unit 60 and the operation processing unit 62 correspond to “operation unit” and “authentication request information receiving unit”, the display unit 58 corresponds to “display unit”, and the video control unit 66 “display control unit”. It corresponds to. The control unit 52 corresponds to “measurement unit”, “detection unit”, “switching unit”, “switching control unit”, and “remote control side control unit”, and the wireless communication unit 54 corresponds to “remote control terminal side reception unit”. The rechargeable battery 70 corresponds to a “power supply unit”.

For example, a USB-LAN converter 6b is provided. The USB-LAN conversion unit 6b is connected to the LAN 100. For this reason, when the remote control terminal 5 is installed in the cradle 6, the remote control terminal 5 is connected to the karaoke apparatus 4 via the LAN 100. As a result, the karaoke apparatus 4 can detect that the remote control terminal 5 is installed in the cradle 6.

The remote control terminal 5 is a remote control B in this embodiment. This process will be described in the “Description of selection process of karaoke apparatus 4” column described later.

  The remote controller B that has received the instruction data to turn on the secondary power supplies the secondary power to the operation unit 60 and the display unit 58. This process will be described in the section “Explanation of performance logout process of remote control terminal 5” which will be described later. The manager guides the user to the room in which the karaoke apparatus 4 that can be used is installed, as indicated by an arrow (5 ').

  First, it is determined whether or not the remote control terminal 5 is associated with the karaoke apparatus 4 (S610). The phrase “remote control terminal 5 is associated with karaoke device 4” means “enabling remote control terminal 5 and karaoke device 4 to communicate”. When the remote control terminal 5 is lent to the user, the user confirms communication with the designated karaoke device 4 and the remote control terminal 5 associates with the karaoke device 4. That is, it is determined whether or not the remote control terminal 5 and the karaoke apparatus 4 can communicate. When it is determined that the remote control terminal 5 is not associated with the karaoke device 4 (S610: NO), the remote control terminal 5 waits until the remote control terminal 5 is associated with the karaoke device 4, and the remote control terminal 5 is connected to the karaoke device 4. When it is determined that the correspondence has been made (S610: YES), the process proceeds to S620.

  In the process of S620, it is determined whether or not the remote control terminal 5 is installed in the cradle 6 (S610).

When the process of S710 is completed, the process proceeds to S720.

  In the process of S720, it is determined whether or not the remote control terminal number of the remote control terminal 5 and the charge state flag have been received. If it is determined that the remote control terminal number of the remote control terminal 5 and the charge state flag have not been received (S720: NO), the remote control terminal 5 waits until the remote control terminal number and the charge state flag are received, If it is determined that the remote control terminal number and the charge state flag have been received (S720: YES), the process proceeds to S730.

  In the process of S730, the remote control terminal number and the charge state flag of the remote control terminal 5 received in the process of S720 are stored in the detected voltage related data memory area 42 of the HDD 16 in association with the remote control terminal number and the charge state flag.

  In the process of S740, it is determined whether or not the remote control terminal numbers of all the remote control terminals 5 have been received. When it is determined that the remote control terminal numbers of all the remote control terminals 5 have been received (S740: YES), the process proceeds to S750. On the other hand, if it is determined that the remote control terminal numbers of all the remote control terminals 5 have not been received (S740: NO), the process returns to S720.

  In the process of S750, the available time is calculated from the charge state flags for all remote control terminal numbers of the remote control terminals 5 received in the process of S720. Specifically, the available time corresponding to the value of the charge state flag in the available time conversion table data memory area 43 of the HDD 16 is extracted. When the process of S750 is completed, the process proceeds to S760.

  In the process of S760, the order m is assigned to the remote control terminal numbers in the descending order of available time extracted in the process of S750, and the order m is assigned to the detected voltage related data memory area 42 of the HDD 16 and the order m.

  First, it is determined whether or not a scheduled use time T2 and a use availability request transmitted by the management apparatus 2 have been received (S210). Specifically, the usage request request for requesting information on availability or non-use of the scheduled use time T2, which is the scheduled time used by the user, transmitted by the management apparatus 2 and the scheduled use time T2 is received. Determine whether or not. If it is determined that the scheduled use time T2 and the availability request have not been received (S210: NO), the system waits until the scheduled use time T2 and the availability request are received, and receives the scheduled use time T2 and the availability request. If it is determined that it has been (S210: YES), the process proceeds to S230.

  In the process of S230, the time of the available time T1 is compared with the time of the scheduled use time T2, and it is determined whether or not the available time T1 is equal to or greater than the scheduled use time T2. Specifically, the available time T1 obtained by adding all available times of the respective remote control terminal numbers stored in the detection voltage related data memory area 42 of the HDD 16 is equal to or larger than the scheduled use time T2 received in the process of S210. Determine whether or not. If it is determined that the available time T1 is equal to or longer than the scheduled use time T2 (S210: YES), the process proceeds to S240. On the other hand, when it is determined that the available time T1 is not the same as or larger than the scheduled use time T2 (S210: NO), the process proceeds to S242.

  In the process of S240, the karaoke device number for identifying the karaoke device 4, the available information indicating that the karaoke device 4 is available, and the available time T1 are transmitted to the management device 2. When the process of S240 is completed, the process proceeds to S245.

  In the process of S245, it is determined whether or not the preparation information transmitted by the management apparatus 2 has been received. If it is determined that the preparation information has been received (S245: YES), the process proceeds to S250.

Then, data indicating the numerical value “0” of the energization flag, which is an instruction to turn off the secondary power supply, is transmitted to the remote control terminal 5 indicating other than the numerical value “1” of the order m. When the process of S250 is completed, the process returns to S210.

[Description of Management Device 2 Selection Processing]
Below, the process procedure of the selection process performed by the control part 2a of the management apparatus 2 is demonstrated based on the flowchart of FIG.7 (b). This process is executed when the management apparatus 2 is activated. FIG. 7B is a flowchart illustrating a procedure of “selection process of the management apparatus 2” executed by the control unit 2a of the management apparatus 2.

If it is determined that the available information has been received (S920: YES), the process proceeds to S922. On the other hand, if it is determined that the usable information has not been received (S920: NO), the process returns to S910.

  In the process of S922, the received karaoke apparatus number and the available time T1 are associated with the available information received in the process of S920 and stored in the available time related data memory area 81 of the HDD 2b. When the process of S922 ends, the process proceeds to S923.

[effect]
According to the karaoke system 1 of the present embodiment, the following operational effects can be obtained. That is, in a karaoke system in which a karaoke apparatus is operated by a plurality of remote control terminals, for example, the remote control terminal has a reduced output voltage level and charge amount of a secondary battery built into the remote control terminal while communicating with the karaoke apparatus, and karaoke performance The service using the remote control terminal, such as the input operation of the reserved song to be performed and the confirmation display of the reserved song, is interrupted. Therefore, it may be possible to prevent the service using the remote control terminal from being interrupted by combining the time available for the karaoke room with the shortest available time of each remote control terminal. However, since the usage time of the karaoke room is set in accordance with the shortest remote control terminal, the available time as the karaoke room is also shortened, and there is a possibility that the fee income as a karaoke shop is reduced. Also, if you wait for the secondary battery to be fully charged until you use the remote control terminal, you can set the maximum available time after it is fully charged, but during that time you cannot use the karaoke room, so for users , More likely to feel frustrated.

  (1) On the other hand, the karaoke system 1 of this embodiment is configured as follows. That is, the control unit 12 of the karaoke apparatus 4 transmits request information requesting that each of the plurality of remote control terminals 5 transmit a charge state flag. Further, when the control unit 12 determines whether or not the charging state flag is received from each of the plurality of remote control terminals 5 and determines that the charging state flag is received from all of the plurality of remote control terminals 5, the HDD 16 stores it. The remote control terminal numbers of the plurality of remote control terminals 5 are sequentially selected from the charge state flags of the plurality of remote control terminals 5 to be executed. The control unit 12 transmits information for requesting the remote control terminal 5 identified by the selected remote control terminal number to supply secondary power to the display unit 58 and the operation unit 60, and the remote control terminal number not selected. Information for requesting all the display units 58 and the operation unit 60 to disconnect the secondary power supply is transmitted to all the remote control terminals 5 identified by. Further, when the control unit 52 of the remote control terminal 5 receives information for requesting the secondary power supply from the karaoke device 4, the secondary power is supplied to the display unit 58 and the operation unit 60. When the control unit 52 receives information for requesting the secondary power supply to be disconnected from the karaoke apparatus 4, the secondary power supplied to the display unit 58 and the operation unit 60 is disconnected. When the controller 52 detects the discharge state flag of the rechargeable battery 70 as a numerical value “0” (the smaller the numerical value, the smaller the charge amount), the remote control terminal number is read from the memory 56 and the read remote control The terminal number and the discharge state flag are associated with the numerical value “0” and transmitted to the karaoke apparatus. Further, when the control unit 12 of the karaoke device 4 receives the remote control terminal number and the discharge state flag “0” from the remote control terminal 5 identified by the selected remote control terminal number, the next remote control terminal number is selected. To do.

  With this configuration, secondary power is supplied only to the display unit 58 and the operation unit 60 of the selected remote control terminal 5, and the display units 58 and operation units 60 of all the remote control terminals 5 that are not selected are supplied. Secondary power is cut off. When the selected remote control terminal 5 detects the discharge state flag of the rechargeable battery 70 as a numerical value “0”, the discharge state flag as a numerical value “0” is transmitted to the karaoke apparatus 4. Then, the next remote control terminal 5 is selected. Therefore, in the karaoke system in which the karaoke apparatus 4 is operated by the plurality of remote control terminals 5, secondary power is supplied only to the display unit 58 and the operation unit 60 of the selected remote control terminal 5 among the plurality of remote control terminals 5. In addition to being usable as a karaoke room, the secondary power supply is cut off to the display unit 58 and the operation unit 60 of the remaining remote control terminal 5, so that the power consumption of the remaining remote control terminal 5 can be reduced. When the karaoke system 1 includes the cradle 6 for charging the rechargeable battery 70 of the remote control terminal 5, the remaining rechargeable batteries 70 of the remote control terminal 5 can be charged. Furthermore, when the selected remote control terminal 5 detects the discharge state flag of the rechargeable battery 70 as a numerical value “0”, the next remote control terminal is selected, so that the use time of the karaoke room can be prevented from decreasing.

  (2) Moreover, the karaoke system 1 of the present embodiment is configured as follows. That is, the control unit 12 compares each available time of each of the plurality of remote control terminals 5 from each available time of the plurality of remote control terminals 5 stored in the HDD 16 and relates to the maximum available time. The remote control terminal number is sequentially selected from the remote control terminal number associated with the minimum available time.

  Since it is configured in this way, the remote control terminal 5 sequentially starts from the remote control terminal number associated with the available time with the longest available time to the remote control terminal number associated with the available time with the smallest available time. Selected. That is, by turning on the power sequentially from the remote control terminal 5 having a large amount of charge (the terminal voltage is the highest in the case of voltage control), it is possible to obtain an effect that does not lower the convenience of the remote control terminal 5 by the user.

(3) Furthermore, the karaoke system 1 of the present embodiment is configured as follows. That is, the control unit 2a of the management device 2 includes the scheduled use time received by the operation unit 2g and the availability request information for requesting to transmit the karaoke device number for identifying the karaoke device and the availability information. It transmits to a plurality of karaoke apparatuses 4. In addition, the control unit 12 of the karaoke device 4 extracts the available time from the detected voltage-related data stored in the HDD 16 and adds the extracted available times to calculate the available time of the karaoke device 4. Further, when the control unit 12 receives the scheduled use time and the availability request information from the management device 2, the control unit 12 compares the available time with the scheduled use time, and determines whether the available time is greater than the scheduled use time. If it is determined that the available time is equal to or longer than the scheduled usage time, the karaoke device number and the available information stored in the HDD 16 and the available time are transmitted to the management device, If it is determined that the available time is smaller than the scheduled use time, the karaoke device number and unusable information stored in the HDD 16 are transmitted to the management device 2. Moreover, when the control part 2a of the management apparatus 2 receives either one of the usable information or the unusable information from each of the plurality of all karaoke apparatuses 4, it determines whether or not the usable information has been received. If it is determined that the available information has been received, the received available time is compared with all the received available information, and the received karaoke including the available time indicating the smallest available time is received. Select the device number.

  Since it is configured in this way, the karaoke device 4 calculates the available time based on the charge state flags of the rechargeable batteries 70 of the plurality of remote control terminals 5, and the calculated available time is determined by the management device 2. If it is the same as or larger than the scheduled use time requested by the user transmitted from, the available information and available time are transmitted to the management apparatus 2. On the other hand, if the calculated available time is shorter than the usage time requested by the user transmitted from the management device 2, the unavailable information is transmitted to the management device 2. Moreover, the management apparatus 2 compares each received available time, and selects the karaoke apparatus 4 which has the smallest available time. That is, the karaoke apparatus 4 having the available time that is longer than the usage time requested by the user but closest to the usage time requested by the user is selected. By selecting the karaoke device 4 having the available time closest to the usage time requested by the user, the number of karaoke devices that can handle the next user can be increased.

  (4) Moreover, the karaoke system 1 of this embodiment is comprised as follows. That is, when the control unit 2a of the management device 2 receives a user ID and password information transmitted from the karaoke device 4 as a registered user who is permitted to log in to the management device 2, the authentication request information is used. Authenticate and allow the authenticated registered user to log in to the management apparatus 2. Further, the control unit 12 of the karaoke apparatus 4 transmits the user ID stored in the HDD 16 to the remote control terminal 5 identified by the selected remote control terminal number and the display request information for requesting the display unit 58 to display the user ID. Then, the non-display request information for requesting not to display the user ID on all the display units 58 is transmitted to all the remote control terminals 5 identified by the remote control terminal numbers that are not selected. Further, when the video control unit 66 of the remote control terminal 5 receives the user ID and the display request information from the karaoke device 4, it controls the display unit 58 to display the user ID, while receiving the non-display request information. In such a case, the display unit 58 is controlled so that the user ID is not displayed.

  According to the karaoke system configured as described above, the display unit 58 of the remote control terminal 5 to be selected displays the user ID, and the display units 58 of all remote control terminals 5 that are not selected do not display the user ID. . Therefore, in the karaoke system 1 that authenticates the user and permits the login to the management device 2, the discharge state flag of the selected remote control terminal 5 becomes the numerical value “0”, and when the next remote control terminal is selected, The logged-in user ID can also be transferred to the selected remote control terminal 5. In addition, when the next remote control terminal 5 is selected, the logged-in user ID is automatically transferred to the selected remote control terminal 5, so that it is possible for the user to log out and log in. There is no need to operate.
