Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation keyboard for a process control device.

[0002]

2. Description of the Related Art The conventional method of using a programmable function key in an operation keyboard is such that the operation portion for operating the programmable function key and the function name assigned to the programmable function key are separated. Indicates an absolute numerical value as a programmable function key NO by printing on the key operation part on the sheet. The user assigns the name assigned to the pasted part of the programmable function key name provided in the upper row of the programmable function key in advance. It was realized by attaching a label with the programmable function key NO attached from the surface of the sheet. However, in the conventional method, since the operation is performed by operating the programmable function key NO described together with the assigned name, the key operation is not intuitive,
Since a large space for attaching the name label is required, the operation space for the programmable function keys becomes small and it becomes difficult to operate. Furthermore, since the name label is attached to the surface of the sheet, there is a problem that the label surface is rubbed by operation and characters are erased or soiled.

[0003]

As described above, the visibility of the programmable function keys of the operation keyboard is determined by the label having both the function name assigned to the programmable function key and the programmable function key NO. It is not intuitive because it is realized by operating the NO key, and the label of the function name is pasted from the surface of the programmable function key sheet of the operation keyboard, and the problem that the characters of the function name disappear or become dirty due to the key operation was there.

An object of the present invention is that the function name itself assigned to the programmable function key can be directly operated in response to the operation of the operation keyboard, the function name of the programmable function key is erased by operation, and the character is displayed on a transparent sheet. There is no show-through, and further, the user can easily change the function name of the programmable function key without changing the function name or using the tool.

[0005]

In order to solve the above-mentioned problems, the present invention uses a sheet on the operation keyboard as a transparent sheet for the operation portion of a programmable function key, and inserts a function name between the sheet and the switch on the back side of the sheet. A pocket is provided and the entrance of the pocket is provided at the edge of the seat surface.
By inserting the sheet between the transparent slide sheets and inserting it from the pocket entrance at the edge of the sheet surface, the programmable function key operation unit on the sheet surface can recognize the function name of the programmable function key through the transparent sheet and the function name itself. It can be operated, and since the function name label is inserted between two slide sheets into the pocket from the front end of the sheet, the function name can be easily changed or exchanged.

[0006]

In other words, by making the sheet structure of the operation keyboard transparent to the programmable function key portion, the function name label of the programmable function key to be inserted into the pocket provided on the back surface of the seat can be recognized from the top surface of the seat. The label should be sandwiched between two transparent slide sheets and the array of programmable function keys should be linear from the sheet edge so that it can be inserted smoothly from the pocket entrance at the edge of the sheet. Function name can be easily changed or replaced without using the transparent sheet for the slide sheet, which does not hinder the identification of the function name label from the top surface of the sheet. By slide sheet Osamu character by the operation of the programmable function keys to be fixed is not able to show-through on the back side of the sheet and disappear by rubbing by. on the other hand,
Since the pocket provided on the back surface of the seat fills the gap by inserting the slide seat, the finger pressure pressed by the finger from the seat surface of the programmable function key can surely operate to the corresponding switch.
