  FIG. 5 is a functional block diagram for explaining a main part of the control function provided in the CPU 80 of the electronic quick sample device 22. The illuminance determining means 104 shown in FIG. 5 determines the illuminance rank detected by the illuminometer 94 in a stepwise manner with a predetermined threshold as a reference. Specifically, when the illuminance detected by the illuminance meter 94 is within a predetermined numerical range for a predetermined time, it is determined that the surrounding illuminance is a predetermined rank corresponding to the numerical range. To do. This rank is most easily divided into two levels: “bright” which is the first rank corresponding to a relatively high numerical range and “dark” which is the second rank corresponding to a lower numerical range. In these numerical ranges, there may be some overlapping portions. Further, when three or more types of function settings are required in the function change control means 106 described in detail below, a mode in which ranking is performed in three or more levels such as “bright”, “normal”, and “dark”. Is also possible.

  The function change setting means 106 changes the function of the electronic quick sample device 22 according to the illuminance detected by the illuminance meter 94. Preferably, the function of the electronic quick sample device 22 is changed according to the illuminance rank determined by the illuminance determination means 104. For example, when the illuminance determination unit 104 determines that the illuminance is “bright” which is a predetermined first rank, the function of the electronic quick sample device 22 is set to the store side, and the illuminance is predetermined. If it is determined that the second rank is “dark”, the function of the electronic quick sample device 22 is set to the user side. Here, the store-side setting is, for example, management of an environment setting function, a maintenance function, etc. that are not used by a user but only by a store clerk in addition to a function related to karaoke performance including a music selection input function to the karaoke device 16.

When the setting is made and it is determined that the illuminance is “dark” which is a predetermined second rank, the function of the electronic quick sample device 22 is set for night. Here, the setting for nighttime is a setting for enabling a night function including contents for adults in addition to a function related to karaoke performance including a music selection input function to the karaoke device 16, for example, for daytime. The setting is a setting in which functions relating to karaoke performance such as a music selection input function to the karaoke apparatus 16 can be executed, and the night function cannot be executed. Since the daytime should be a general setting for families, etc., there is incident light from the window and so on, and the illuminance is high. The function that suits the usage situation can be set as appropriate. The function setting database 102 stores the illuminance rank determined by the illuminance determination means 104 as described above in association with the function settings of the electronic quick reference device 22, and the function change control means. Preferably, 106 reads out the function setting stored in the function setting database 102 and changes the function of the electronic sample device 22 according to the illuminance rank determined by the illuminance determination means 104.

  The function setting transmission unit 108 stores function setting information stored in the function setting database 102, that is, information corresponding to the relationship between the illuminance rank determined by the illuminance determination unit 104 and the function setting of the electronic quick sample device 22. Then, the data is transmitted to another electronic quick sample device 22 via the LAN 24 or the like. As a result, the information stored in the function setting database 102 of each electronic quick sample device 22 is shared, and the contents are equivalent. In order to store the illuminance rank determined by the illuminance determination means 104 and the function setting of the electronic quick sample device 22 in association with each other in the function setting database 102, the electronic quick sample device 22 is set in each use environment in advance. It is necessary to perform an operation of arranging and detecting each illuminance by the illuminance meter 94 and storing it. However, if such an operation is performed in the predetermined electronic quick reference apparatus 22 as long as the equivalent processing is performed, As a result, it is possible to eliminate the complexity of performing the work one by one in each electronic quick sample device 22.
