After the start of the 5-second timer in step S2, the elapse means measures the remaining time, and in step S3, the operation elements other than the engine-start operation element 12 are turned off and the remaining time of the 5-second timer becomes 0 seconds. If not, the process proceeds to step S4. In addition, 5 seconds of the 5-second timer is the predetermined addition time.

  In step S4, it is determined whether or not the operation element 12 for starting the engine is ON. If the operation element 12 is not ON, the process returns to step S3, and this operation is repeated until 5 seconds have elapsed. If there is no ON signal from 15 and 5 seconds have elapsed, the engine start operation is terminated in step S9. That is, when 5 seconds elapse (tS3) after the start of the 5-second timer, the engine does not start even if the operation element 12 for starting the engine is turned on.

  When the operation element 12 for starting the engine is turned on during the repetition of steps S3 and S4, the process proceeds to step S5, the one-second timer starts, and after the one-second timer starts, the process proceeds to step S6. In step S6, it is determined whether the engine start operating element 12 is on, that is, whether or not the other operation elements 11, 13, 14, and 15 are off, and whether the engine start operation element 12 is on. If the other operating elements 11, 13, 14, and 15 are off, the process proceeds to step S7, and it is determined whether the 1-second timer is 0. If not, the operation returns to step S6. If the element 12 is on and the other operating elements 11, 13, 14, 15 have been off for 1 second, that is, if at least only the engine starting operating element 12 has been pressed for 1 second, an engine start signal is issued in step S8. Output and the engine starts.

  On the other hand, when the engine starting operating element 12 is on and the other operating elements 11, 13, 14, 15 are off for less than one second, or during the less than one second, the other operating elements 11, 13, 14,. When the switch 15 is turned on, the process shifts from step S6 to step S9, and the engine start operation ends.
