Abstract

A work vehicle is disclosed with an information displaying device preventing set information corresponding to a setting screen displayed on a display from being erroneously changed even while permitting an operation for switching to and displaying one among a plurality of set screens on the display. A setting information processing unit of the information displaying device includes setting screen displaying means for switching the setting screen by the input of a first operation information item and displaying same in a transition display mode, and setting information changing means for performing a process in an information change mode for permitting a change to the set information corresponding to the setting screen, by inputting of a second operation information item. When it is determined that the second operation information item is inputted in the information change mode, a process for restoring the transition display mode from the information change mode is performed.

Claims

1. A work vehicle comprising:

a display; and

an information displaying device, the information displaying device including;

a setting information processing unit for displaying, on the display, a setting screen selected from among a plurality of set screens corresponding to a plurality of information items, and for changing the set information corresponding to the selected setting screen; and

operation information discriminating means for determining a first operation information item and a second operation information item inputted by a manual operation;

wherein the setting information processing unit includes;

setting screen displaying means for displaying the setting screen on the display; and

setting information changing means for allowing changing of the set information when the setting screen is displayed on the display;

wherein, when the operation information discriminating means determines that the first operation information item is inputted, the setting screen displaying means performs display processing in a transition display mode for sequentially switching to, and displaying one of the plurality of set screens on the display each time an input is determined; and

wherein, when the operation information discriminating means determines that the second operation information item is inputted during display in the transition display mode, the setting information changing means performs a process for moving to an information change mode for allowing changing of the set information corresponding to the setting screen being displayed on the display; and

when the operation information discriminating means determines that the second operation information item is inputted during the information change mode, the setting information changing means performs a process for restoring the transition display mode from the information change mode.

2. The work vehicle according to claim 1, wherein

when the operation information discriminating means determines that the first operation information item is inputted during the information change mode, the setting information changing means changes the set information corresponding to the setting screen each time an input is determined.

3. The work vehicle according to claim 1, further comprising:

storage means;

wherein, when the operation information discriminating means determines that the second operation information item is inputted during the information change mode, the set information changed during the information change mode is stored into the storage means.

5. The work vehicle according to claim 1, further comprising:

a first switch; and

a second switch;

wherein the operation information discriminating means determines if the first operation information item is inputted or not when the first switch is operated, and determines if the second operation information item is inputted or not when the second switch is operated.

6. The work vehicle according to claim 1, further comprising:

a first switch;

a second switch; and

a single operational tool for operating the first switch and the second switch;

wherein the operation information discriminating means determines if the first operation information item is inputted or not when the first switch is operated by the operational tool, and determines if the second operation information item is inputted or not when the second switch is operated by the operational tool.

4. The work vehicle according to claim, further comprising:

a push switch;

wherein the operation information discriminating means determines if the first operation information item is inputted or not when a period of time of operation by the push switch is less than a set of period of time, and determines if the second operation information item is inputted or not when the period of time of operation by the push switch is the set of period of time or longer.
