<p>PURPOSE:To improve operability without increasing the number of operating keys by making it possible to perform traveling direction mode indicating operation and traveling direction switching operation through a single operating key at the time of stoppage. CONSTITUTION:If a stop key is depressed for longer than 2sec, for example, a decision is made that a traveling direction mode switching operation is performed. In other words, if a stop key 4 is depressed continuously and a decision is made that the count of a timer has exceeded 2 sec, traveling direction mode information stored as last memory function is inverted. In other words, stored content is modified to reverse traveling mode if the current mode is a normal traveling mode whereas the stored content is modified to normal traveling mode if the current mode is a reverse traveling mode. At the same time, indications on LED indicating sections 6, 7 are switched.</p> |
