In accordance with the operation of the transport completion key 6d, the transport instruction data stored in the memory 31a which has been transported is erased.

Next, the operation and effect of the mobile communication device configured as described above will be described. The management computer 23 sequentially creates transport instruction data based on the transport request data input from the keyboard 24, and stores it in the memory 23a. That is, the forklift 1 is stored in the memory 23a.
The transport instruction data for carrying out the transport work is stored.

When the driver operates the data request key 6a of the data terminal 3, the terminal controller 31 sends a data request signal to the management computer 31 via the wireless device 2 or the like. When the management computer 31 receives the data request signal, the management computer 31 transmits all the conveyance instruction data stored in the memory 23a to the terminal controller 31 together with the elapsed time data.

When the terminal controller 31 receives all the transportation instruction data and the elapsed time data, the terminal controller 31 performs a normal display process. That is, the terminal controller 31 stores the contents of all the received transport instruction data and the elapsed time data in the memory 31a for each transport instruction data and displays them on the display 7 as shown in FIG. That is, on the display 7, the product name, the product number, the transport source, the transport destination, and the elapsed time of the load are sequentially displayed from the transport instruction data with the longest elapsed time (the transport instruction data requested to be transported first). It should be noted that the screen of the display 7 can display five pieces of transport instruction data. When five or more pieces of transport instruction data are received, the other transport instruction data not displayed are operated by the cursor key 6e. Then, the screen of the display 7 can be displayed on the display 7 by scrolling.

From the normal display state shown in FIG. 6, the driver operates the cursor key 6e to select the transport instruction data indicating the desired load to be transported. In FIG. 6, the transport instruction data surrounded by the two-dot chain line at the top is selected.

A search is performed based on the similar transport source data stored in a, and the content of the transport instruction data including the similar transport source is displayed on the display 7. In this case, since the transport source of the selected transport instruction data is the load storage area A1, the similar transport sources are the load storage areas A1, A2, B1, B2. Therefore,
As shown in FIG. 7, the terminal controller 31 determines that the carrier is the loading area A from all the received carrier instruction data.
1, A2, B1 and B2 are searched for transport instruction data,
The retrieved transportation instruction data is displayed on the display 7.

On the other hand, from the normal display state, the driver operates the cursor key 6e to select the transport instruction data indicating the desired load to be transported (two-dot chain line in FIG. 6). And
When the similar transport destination key 6c is operated in this selected state, the terminal controller 31 performs similar transport destination display processing. That is, the terminal controller 31 searches for the similar transport destination indicated by the selected transport instruction data from all the received transport instruction data based on the similar transport destination data stored in the memory 31a, and determines the similar transport destination. The contents of the transport instruction data including the data are displayed on the display 7. In this case, since the destination of the selected transport instruction data is the production line L2, the similar destinations are the production lines L1, L2, L3.

The cursor key 6e is operated to select on either the display screen or the similar transfer destination display screen, and the transfer completion key 6d is operated. Then, the terminal controller 31 transmits a transport completion signal to the management computer 23 and erases the transport instruction data selected by the cursor key 6e stored in the memory 31a. Then, when the management computer 23 receives the transportation completion signal, it erases the transportation instruction data indicating that the transportation is instructed by the transportation completion signal.

According to this embodiment, the following (a) to (d)
It has the effect of (e). (B) When the transport instruction data is normally displayed on the display 7, the transport instruction data of a predetermined load to be transported is selected, and the similar transport source key 6b is operated, whereby the transport source of the transport instruction data is selected. With respect to, it is possible to display the contents of the transport instruction data having a transport source that is a similar transport source. That is, the similar transport source display can be performed on the display 7. Therefore, by visually recognizing the similar transport source display on the display 7, the driver of the forklift 1 determines whether or not there is a load-instructed load near the load-holding area where the load to be transported is placed. It can be easily and quickly determined. For this reason, in addition to the predetermined load, it is possible to easily find on the display 7 a load that is near the load and has already been instructed to be transported, and perform the unloading with the forklift 1. Therefore, the transfer work by the forklift 1 can be efficiently performed.

(B) When the transport instruction data is normally displayed on the display 7, the predetermined transport instruction data of the load to be transported is selected, and the similar transport destination key 6c is operated. It is possible to display the content of the transport instruction data having a transport destination that is a similar transport destination with respect to the transport destination of. That is, it is possible to display a similar destination on the display 7. Therefore, by visually recognizing the display of the similar destination on the display 7, the driver of the forklift 1 determines whether or not there is a similar load at the destination 12 with the predetermined load to be transported. Easy and quick to judge. For this reason, in addition to the predetermined load, it is possible to easily find on the display 7 a load whose delivery destination is similar and which has already been instructed to be transported, and perform the unloading with the forklift 1. Therefore, the transfer work by the forklift 1 can be efficiently performed.

(C) The display 6 has a keyboard 6
Since the similar transport source display or the similar transport destination display can be performed based on the operation of, the transport work can be performed more efficiently by appropriately selecting the display state based on the type of the load transport work and the like. . For example, when picking up items in sequence from a specific transport source (load storage area A1), similar transport source display is performed, and a specific transport destination (production line L
1) When it is desired to supply a load only to the vicinity, the similar transport destination display is performed, so that each transport operation can be efficiently performed.

(D) The transfer instruction data having the similar transfer source or the similar transfer destination with respect to the selected transfer instruction data is searched for in the transfer instruction data received by the terminal controller 31. That is, the search is performed on the data terminal 3 side. Therefore, it is not necessary to newly communicate with the management computer 31, and it is possible to quickly search for the transport instruction data having the similar transport source or the similar transport destination.

(E) Memory 31 of terminal controller 31
Since the similar transport source data and the similar transport destination data are stored in a, it is better to search the transport instruction data having the similar transport source or the similar transport destination based on the similar transport source data or the similar transport destination data. It can be done easily and quickly.

The present invention is not limited to the above-mentioned embodiment, and may be appropriately modified and implemented without departing from the spirit of the invention. (1) In the above-described embodiment, the transport instruction data having similar transport sources and transport destinations may be retrieved and displayed on the display 7. In this case, for example, the target conveyance instruction data is selected, the similar conveyance source display process is performed, and the similar conveyance source is displayed on the display 7. Then, the target conveyance instruction data is selected again on the screen. Then, the terminal controller 31 performs the similar destination display processing on the transport instruction data having the displayed similar transport sources. Therefore, on the display 7, it is possible to display the transportation instruction data in which the transportation source and the transportation destination are similar. Of course, the same result can be obtained by performing the similar transport source display process after the similar transport destination display process.

(2) In the above embodiment, the memory 31a
The similar transport source and the similar transport destination data are stored in. Alternatively, the terminal controller 31 may calculate the similar transport source and the similar transport destination. In this case, condition data for determining the similar transport source and the similar transport destination is stored in the memory 31a in advance, and the terminal controller 31 selects the similar transport source and the similar transport destination based on the condition data. That is, the transport source and the transport destination that satisfy the condition indicated by the condition data are the similar transport source and the similar transport destination.

For example, the condition data for determining a similar loading area as a similar transport source is located in the same or adjacent row to the target loading area and is the same or adjacent to the loading area. This is data for determining whether or not the cargo storage area is located in a row. The condition data for determining the similar production line as the similar transport destination is data for determining whether the production line is the target production line itself or the adjacent production line. Similarly, the condition data for determining the similar delivery area as the similar delivery destination is data for determining whether the delivery area is the target delivery area itself or an adjacent delivery area.

(3) In the above embodiment, the management computer 31 may search for the similar transport source and the similar transport destination. (4) In the above embodiment, the similar transport source and the similar transport destination indicated by the target transport instruction data are the same transport source and transport destination as the target (self) transport instruction data. It may be removed. For example, the similar loading area for loading area B3 is loading area A
2, A3, A4, B2, B4, C2, C3, C4.

(5) In the above embodiment, for example, the similar transport source may be the loading area located in the same row as the transport source of the target transport instruction data. Similarly, the load storage areas may be located in the same station.

Further, for example, the range of similar transportation destinations may be divided into the production lines L1 to L5 and the transportation areas T1 to T5. That is, when the destination of the target transportation instruction data is any one of the production lines L1 to L5, all the production lines L1 to L5 are similar destinations, and the destination is one of the delivery areas T1 to T5. In the case of one, all the delivery areas T1 to T5 may be the similar destinations.
