Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a touch panel type multi-item input device, and is particularly suitable for use in a touch panel type multi-item input device configured by mounting a transparent touch panel on the front surface of a display device. It is something.

<Prior Art> As is well known, for example, as disclosed in Japanese Patent Laid-Open No. 63-213017, there is a touch panel type multi-item input device having a structure in which a transparent touch panel is attached to the front of a display device for displaying item keys and the like. Are known. As shown in the perspective view of FIG. 5, such an input device includes a display device 11 for displaying item keys and the like, a touch panel 12 attached to the front surface thereof,
It is composed of a screen switching key 42 for switching the contents displayed on the display surface of the device 11, a function key 15, a memory switching switch 41 and the like.

Next, the operation of the conventional touch panel type multi-item input device configured as described above will be described with reference to the functional block diagram of FIG.

The entire operation of the touch panel type multi-item input device of FIG. 6 is controlled by a control unit 50 including a CPU, a program memory (ROM), a general-purpose memory (RAM) and the like. That is,
Based on the switching state of the memory changeover switch 41, the control unit 50 controls the memory with battery backup (BBM) 2
Select 1 or memory card 16. Then, the item key display data for the predetermined screen No. is read out from any one of the above memories and stored in the video memory 22, and the display device 11 is instructed to display the item key.

The item key displayed on the display device 11 is input via the transparent touch panel 12 and sent to the host device (not shown) by the interface 23.

Further, when the screen switching key 42 is pressed, the control unit 50 selects either the memory 21 with the battery backup or the memory card 16 from the state in which the memory switching switch 41 is set in exactly the same procedure as described above. The item key corresponding to the selected and entered screen number is displayed on the display device 11. Further, the input data of the function key 15 is also sent to the host device by the interface 23. Further, as shown in FIG. 5, the screen switching key 42 is used for the current task, that is, the selected memory (memory 21 with battery backup or memory card 16).
A key display sheet 43 displaying a table of contents for each screen No. of the key display data stored in is installed. Therefore, the operator can confirm the table of contents of each screen No. by the key display sheet 43 for each item key display data (that is, memory) and switch the screen displayed on the display device 11.

<Problems to be Solved by the Invention> Therefore, in the device having the above-described configuration, the item key display data (that is, the memory) to be displayed on the display device 11 is selected by the memory changeover switch 41 in accordance with the work, and at the same time, the screen changeover key 42 is selected. Since the key display sheet 43 for the vehicle must be replaced, there is a problem that the operation is very troublesome. Further, on the key display sheet 43, only the table of contents of the screen No. of one memory can be described substantially due to the space and the size of the marked characters. Therefore, for example, the item key display data (that is, the memory) is stored in the memory 21 with battery backup and the memory card
In the case of a business that uses both of these, the key display sheet is conventionally used every time the memory changeover switch 41 is changed.
The operation was very cumbersome as I had to replace the 43. In order to eliminate such troubles, in the business where both of the above item key display data (that is, memory) is used, for example, by using the key display sheet 43 that displays only the screen No. at the end, the memory The key display sheet 43 does not have to be replaced when the key is switched. Therefore, in this case, the screen No. (substantially double the screen N
Since it is necessary to check only o.) and operate the screen switching key 42 without a table of contents, it is easy to cause a screen switching error and the operability is significantly deteriorated.

In view of the above problems, it is an object of the present invention to prevent a screen switching mistake from occurring in a job that uses both item key display data (that is, memory) and to improve the operability of screen switching.

<Means for Solving the Problems> The touch panel type multi-item input device of the present invention has a transparent touch panel attached to the front surface of the display device and uses both a battery backup memory and a removable memory card. These memory and memory card with battery backup store display information consisting of at least display data of the item keys and display data of the screen switching keys, and the item keys in the transparent touch panel area. In a touch panel type multi-item input device to which a screen switching key is assigned, means for changing the display of the screen switching key displayed on the display surface of the display device, and the display on the memory with battery backup and the memory card. Check if the information is stored Based on the output means, the display changing means, and the output of the display information detecting means, it is determined whether the screen switching keys are simultaneously accessed to the two memories or one of the memories is independently accessed. And means for doing so.

<Operation> Detects whether the information of the screen switching key displayed on the display surface is stored in the battery backup memory or the memory card, and determines the memory to be accessed based on the detection result. By automatically changing the contents displayed on the display surface, whether the data for the screen switching key display is stored in the battery backup memory or the memory card, or in both of these memories. The item key input can be performed without the operator being aware of whether the data is stored over.

<Embodiment> FIG. 1 is a perspective view of a touch panel type multi-item input device showing an embodiment of the present invention.

As shown in FIG. 1, the touch-panel type multi-item input device 10 of the present embodiment includes a display device 11 for displaying item keys and screen switching keys, a transparent touch panel 12 mounted on the front surface of the display device 11, and a memory. It is composed of a card 16 and a screen switching key change key 17 for instructing a display change of the screen switching area 13. Further, the touch panel 12 and the display device 11 are functionally divided into a screen switching area 13 and an item key area 14 and controlled.

FIG. 2 is a functional block diagram of this embodiment, and FIG. 3 is a block diagram showing a detailed configuration of a control unit 20 for controlling the operation of the touch panel type multi-item input device of the embodiment.

In FIG. 2, a control unit 20 for controlling the entire apparatus is composed of a CPU, a program memory (ROM), a general-purpose memory (RAM), etc., as in the conventional apparatus. This control unit 20
Is the correct display data stored by reading the display data (that is, the item key display data and the table of contents data for the screen switching key display) stored in the memory 21 with battery backup and the memory card 16 from both memories? Whether or not it is detected by the display data detecting means 31. If the display data is correct, it is determined that the specified data is stored in the specified address of each memory, and whether the display data is correct is determined by the hash value or parity check. You can use the general method of.

By the way, the display data is stored in the following three cases. That is, in the first case, as shown in FIG. 4 (a) which is an explanatory view of the display content changing means, the display data is the memory 21 with the battery backup.
And the case stored in the memory card 16. The second case is a case where it is stored only in the memory 21 with a battery backup as shown in FIG. 4 (b), and the third case is a memory card 16 as shown in FIG. 4 (c). It is the case that is stored only in. In addition,
In the following description of this embodiment, the display data is “P1 to P40”.
It is assumed that 40 screens of are stored in one memory.

In the apparatus of the embodiment configured as described above, the control unit
When the display data detection means 31 obtains the result that the display data is stored in the first case, the display control means 32 causes the display control means 32 to switch the display data from the display data in the memory 21 with the battery backup to the screen switching area 13 Then, the table of contents data “P1 to P20” is displayed as the display of this key, and the item key of the “P1” screen is displayed on the display device 11 via the video memory 22 as the display of the same key in the item key area 14. Here, when the operator touches the item key area 14 via the transparent touch panel 12, it is detected by the touch panel detection means 33, and if it is detected that the touched key is an item key, it is currently displayed. It is obtained from the display control means 32 that the screen No. that is present is the screen of the memory 21 with battery backup, for example, "P1", and the input means including the item key coordinates and the like is generated by the transmission means 34, and the interface is generated. It is sent to the host device via 23.

When the operator touches the screen switching area 13 via the transparent touch panel 12, the touch panel detection means 33 detects that the input key is the screen switching key and sends the input coordinates to the display control means 32. The display control means 32 uses the input screen switching key coordinates, for example, in the case of the "P5" screen No., to display the "P
5 ”screen item key display data is displayed Data detection means 31
Through the video memory 22 and the display device 11 through the video memory 22.
Change the item key display contents of the item key area of.

Further, when the operator inputs the screen switching key change key 17, the control unit 20 detects it by the change key detection means 35 and sends the input information of the up key to the display control means 32, for example. The display control means 32 changes the display content displayed on the display surface from the input up key information in accordance with the explanatory diagram of the procedure for changing the display content of the screen switching key shown in FIG. In this case, which is Step 2 of the first case, the contents data "P21 to P40" as the key display of the screen switching area 13 from the display data of the memory 21 with battery backup is displayed in the same manner as in the above-mentioned procedure. 11 screen switching area 13 screen switching key Changes the displayed contents.

As described above, in the case of the touch panel type multi-item input device of the embodiment, since the target screen is displayed by combining the screen switching key change key 17 and the screen switching key, the display data is stored in two memories. It becomes possible to input item keys without paying attention to which one is stored. Therefore, it is possible to facilitate a series of operations for inputting item keys, reliably prevent screen switching mistakes in business using both of the two memories, and improve operability.

Although only the screen up key is shown as the screen switching key in the procedure explanatory diagram of FIG. 4, the procedure of the screen switching key down key is the same as that of the up key described above except that the direction is completely reversed. So I omitted it. further,
The key input of the function key 15 is detected by the function key detecting means 36, and is sent out to the host device through the interface 23 by the sending means 34.

Further, in the above-described embodiment, the screen switching key changing key 17 has a mechanical key structure and is mounted on the main body of the apparatus, but it may be arranged on the transparent touch panel 12 to make the key display variable. .

<Effects of the Invention> As described above, the present invention assigns a screen switching key to a transparent touch panel mounted on the front surface of a display device, and the information of the screen switching key displayed on the display surface is stored in a memory with a battery backup. Or, it detects which memory card is stored, determines the memory to access based on the detection result, and automatically changes the contents displayed on the above display screen. The item key input should be performed without the operator being aware of whether the data for key display is stored in the battery backup memory or memory card, or whether it is stored in both of these memories. Can be done. Therefore, even in the case where the user uses both the memory with battery backup and the memory card, the operator can handle the above two memories as continuous display data, and it is troublesome to switch between the memory with battery backup and the memory card. Since it is possible to eliminate the problem and to easily confirm the display contents, it is possible to eliminate mistakes when switching to the target screen, and it is possible to greatly improve operability.
