  As shown in FIG. 3, in the conventional multifunctional electronic device 901, each unit has only a motor and a pointer, and does not have a control unit. Therefore, the main controller 904 needs to generate and drive the drive signals of the motors (957, 967). This drive signal needs to be created by the creator of the control program of the main control unit 904. However, in order to control the stepping motor, it is necessary to understand the characteristics of the stepping motor mounted in the unit and the driving method of the stepping motor (forward rotation, reverse rotation, stop, step out prevention, etc.). Therefore, for example, when an attempt is made to configure a smart watch (multifunctional electronic device) using the first pointer driving motor unit 905 and the second pointer driving motor unit 906, a control program for the main controller 904 is created. Burden on the person. Further, as shown in FIG. 3, the main controller 904 needs to drive the first pointer driving motor unit 905 and the second pointer driving motor unit 906, so that the main controller 904 has a large load. It was Further, if the multifunctional electronic device 901 has a communication unit (not shown) and communicates with a smartphone (multifunctional mobile phone) (not shown), compared with the processing of a general multifunctional electronic device. The processing of the main control unit 904 increases. Therefore, in the multi-function electronic device 901 of the related art, for example, when the number of units increases and the number of processes for driving the units increases, the communication with the smartphone is disturbed, and when the communication with the smartphone increases, the control of the unit is disturbed. There was a case to come out.

  On the other hand, in the present embodiment, the main control unit 4 can control other units by outputting a command instead of a drive signal only to the first pointer driving motor unit 5. As a result, the creator of the control program of the main control unit 4 may create a control program for sending a command in which information indicating the unit to be operated is embedded to the first pointer driving motor unit, and therefore the creator's burden. Is reduced. Further, since the main control unit 4 exchanges information with only the first pointer driving motor unit 5 even if there are a plurality of units, the load on the main control unit 4 is reduced. Furthermore, according to the present embodiment, the control program creator of the main control unit 4 does not need to understand the characteristics of the stepping motor or the method of generating the drive signal, and can change the target time or change the mode such as the countdown timer mode. Since it is only necessary to give an instruction or the like, it is possible to significantly reduce the load of the control program creator in creating the program.
