When the smallest size key is moved up by one step so that the smallest size key always becomes the smallest size, 100 is subtracted from the variable F representing the key size for all the keys. The size may be reduced by one step. Further, all key sizes may be reset to a normal size by performing a special operation.

As described above, in the first embodiment and the second embodiment,
The number of times each key was pressed was counted, and the key display was changed so that it could be distinguished from other keys by the frequency of use.
In the third embodiment, regardless of the number of times the key is pressed, the operator designates a key to be set with priority in advance on the priority setting screen, so that the display of the key is different from the display of other keys. This is a method of changing to a display form that can be distinguished.

FIG. 11 shows a copy format setting screen among the priority setting screens in which the operator specifies a key to be set in advance. When the operator presses the priority setting start key 111, the mode is switched to the user choice mode, and the operator can select a key by touching a key whose display form is to be preferentially changed on the switched screen.

FIG. 12 is a flowchart showing the input processing (step S103 in FIG. 5) in the third embodiment.

First, it is determined whether or not the key pressed by the operator is the print key 61 or the reset key 65 on the operation panel 50 or an input on the touch panel. If the key is not an input on the touch panel (step S71).
And NO), and performs other processing (for example, processing for displaying the number input by the ten keys) (step S80), and returns.

In the case of input on the touch panel (step S
At 71, the following processing is executed. First, the input key is the priority setting start key 11 on the touch panel 51.
If it is 1 (YES in step S72), 1 indicating that priority is being set is substituted for a variable Y indicating whether priority is being set (step S73). Next, the key type is determined from the key matrix corresponding to the value of the screen variable G corresponding to the screen display on the touch panel 51 and the position where the touch switch 53 is pressed (step S74). Then, the key pressed by the operator is input to a variable D for changing to a large-size key, and 1 indicating that rewriting is to be performed is substituted for a flag K for screen rewriting (step S75),
To return.

As described above, by pressing the priority setting start key 111, a screen for changing the key display of the function to be preferentially selected and set is entered, and the key to be preferentially set is selected on the screen. The display of the key can be changed by the screen display processing of FIG. In addition, as the key whose display is different from the display of other keys, in addition to the above-described key size increase, a key change color may be considered.

If the priority setting start key 111 has not been turned on (NO in step S72), it is determined whether the variable Y indicating whether priority setting is being performed is 1 or not (step S76). If the priority setting is 1 (YES in step S76), the flow proceeds to step S74 to perform the priority setting, and performs the processing described above.

If priority setting is not being performed (step S7)
6 is NO), it is determined whether the priority setting end key 112 has been pressed (step S77). If the priority setting end key 112 is pressed (YES in step S77), a variable Y indicating whether priority setting is being performed is set to 0 indicating the end of priority setting (step S78), and the process returns. If the priority setting end key 112 has not been pressed (N in step S77)
O), perform other processing (step S79), and return.

As described above, in the first, second, and third embodiments, the method of changing the display of a key having a large number of presses, a key having a small number of presses, and a key whose priority is desired to be set to a display form different from the display of other keys is described.
