To provide a forklift with an updatable software program.SOLUTION: A microcomputer 312 has a first communication port COM1 and a second communication port COM2. A peripheral device 314 is connected to the first communication port COM1 of the microcomputer 312 via a first path P1. A communication circuit 316 is connected to the second communication port COM2 of the microcomputer 312 via a second path P2, and is connected to the first communication port COM1 of the microcomputer 312 via a third path P3. The communication circuit 316 can communicate with a removable external device. A switcher 318 switches between valid/invalid of communication via the third path P3.SELECTED DRAWING: Figure 3

    【課題】ソフトウェアプログラムを更新可能なフォークリフトを提供する。【解決手段】マイコン312は第1通信ポートCOM1および第2通信ポートCOM2を有する。周辺デバイス314は、マイコン312の第1通信ポートCOM1と第1経路P1を介して接続される。通信回路316は、マイコン312の第2通信ポートCOM2と第2経路P2を介して接続され、マイコン312の第1通信ポートCOM1と第3経路P3を介して接続される。通信回路316は着脱可能な外部機器と通信可能である。切替器318は、第3経路P3を介した通信の有効/無効を切り替える。【選択図】図3
