A plurality of setting data are stored.

Further, the RAM 28 is provided with a data memory for storing data of various setting contents corresponding to each of the setting item names. However, the data of the setting contents stored in the data memory sequentially indicates, for each layer, a pointer value 1KP of the first layer pointer that sequentially indicates the operation mode of the first layer and the operation mode of the second layer. The second layer pointer value 2KP of the second layer pointer and the third layer pointer value 3KP of the third layer pointer sequentially designating the setting items of the third layer are identified and stored.

Next, the routine of the setting content setting control performed by the microcomputer 25 will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. When the mode key 11 is operated, this control is started. First, "interface mode" is displayed on the display 10 as the first first operation mode (S10), and the first operation mode number (for example, , “1”) are set (S11). Next, when the ↓ key 14 is operated to select the next operation mode (S12 · S
13: Yes), the first layer pointer value 1KP is incremented by one (S14), the next first layer operation mode name is displayed on the display 10 (S15), and the process returns to S12. When the ↑ key 13 is operated (S12:
(Yes, S13: No, S16: Yes), the first layer pointer value 1KP is decremented by one (S17), the previous first layer operation mode name is displayed on the display 10 (S18), and the process returns to S12.

On the other hand, when the set key 12 is operated (S12: Yes, S13 / S16: No, S19:
Yes), it is determined based on the first layer pointer value 1KP. That is, when the first layer pointer value 1KP is in the "interface mode", the interface type setting process (S21) is executed, and the process returns to S10. Also, the first
When the layer pointer value 1KP is in the “rough mode”,

When the set key 12 is operated (S112: Yes, S113 / S116: No,
S119: Yes), the flag data of the lock flag LF is rewritten and stored in the set data lock mode indicating a new lock state based on the second layer pointer value 2KP (S120), and in order to notify the completion of the setting, "*" Is additionally displayed on the display 10 in addition to the display of the newly set lock mode name (S121), and this control ends and the setting content setting control ends. For example, as shown in FIG. 13, “Lock = On *” is displayed when “Lock = On” indicating the prohibition mode, and “Lock = Off *” is displayed when “Lock = Off” indicating the permission mode. Is done.

Next, a routine of the interface type setting processing control will be described with reference to the flowchart of FIG. When this control is started, first, based on the first layer pointer value 1KP and the second layer pointer value 2KP,
The data of the interface name that has already been set is read from the predetermined storage area of the RAM 28, the interface name is displayed (S30), and the second layer pointer value 2K is displayed.
The number SN of the operation mode name of the interface name in the second hierarchy 2K is set to P in the second hierarchy pointer value 2KP (S31). And S112 to S11
8, each time the ↓ key 14 or the ↑ key 13 is operated, the operation mode name of the next second hierarchy or the operation mode name of the previous second hierarchy is sequentially displayed (S32 to S38), and S3 is performed.
Return to 2. That is, the operation of the ↓ key 14 sequentially displays “Centronics” → “RS-232C” → “auto interface”, and the operation of the ↑ key 13 sequentially displays the order in the reverse order.

Next, when the set key 12 is operated (S32: Yes, S33 / S36: No, S39: Y
es), when the lock flag LF is not set (S40: No), the interface name newly set based on the second layer pointer value 2KP is stored in the RAM 28 (S41), and further added to the interface name. "*" Is additionally displayed (S42), and the routine goes to S44. However, when the lock flag LF is set (S40: Yes), a message "change prohibition" indicating that the mode is the prohibition mode is displayed on the display 10 for about one second (S43), and the process proceeds to S44. For example,
When “RS-232C” is newly set and the permission mode is set, as shown in FIG.
“RS-232C *” is displayed on the display 10. On the other hand, when the prohibition mode is set,
As shown in FIG. 5, a message “change prohibited” is displayed on the display 10.

Next, in step S44, the second layer pointer value 2KP is searched. When the pointer value 2KP indicates "Centronics", the control is terminated and the process returns to step S10 of the setting content setting control. However, when the pointer value 2KP indicates "RS-232C", the communication protocol setting process control (see FIG. 7) is executed (S45), and the pointer value 2KP indicates "auto interface". Is set, the setting process control such as the communication protocol (see FIG. 9) is executed (S4).

The item names of the next third layer 3K and the setting contents are sequentially displayed. Each time the @ key 13 is operated, the pointer value 3K is displayed.
P is decremented, and the item names of the previous third hierarchy 3K and the setting contents are sequentially displayed (S52 to S5).
8) Return to S52.

When the set key 12 is operated (S52: Yes, S53 / S56: No, S59:
If the item name indicated by the third-layer pointer value 3KP is “EXIT” (S60: Yes), the control is terminated and the process returns to S10 of the setting content setting control. However, when the item name indicated by the third hierarchy pointer value 3KP is other than “EXIT” (S60: No), the item content setting process (see FIG. 8) is executed (S61).
This control is started, and every time the ↓ key 14 is operated, the next item contents related to the currently displayed communication protocol item are sequentially displayed (S71 to S72), and the process returns to S71. Every time the @ key 13 is operated, the contents of the previous item are sequentially displayed (S73 to S74), and the process returns to S71.

When the set key 12 is operated (S70: Yes, S71 / S73: No, S75:
When the lock flag LF is not set (S76: No), the setting contents of the newly set communication protocol item are stored in a predetermined storage area of the RAM 28 (S77), and the item name and item contents are further set. In addition to"*"
Is additionally displayed (S78), and the routine goes to S80. However, when the lock flag LF is set (S
76: Yes), the message "change prohibited" is displayed on the display 10 for about one second (S79), and the routine goes to S80. For example, when the setting content “9600” of the communication protocol item name “baud rate” is newly set and the permission mode is set, “baud rate = 9600 *” is displayed on the display 10 as shown in FIG. You.
On the other hand, when the prohibition mode is set, as shown in FIG.
Displayed as 0.

Next, the third layer pointer value 3KP is incremented by one (S80), and when the pointer value 3KP does not indicate the item name "EXIT" (S8).
1: No), the next third layer item name (communications protocol item name) and its item contents are displayed (S82), and the steps from S71 are executed to set the contents for the next communication protocol item. That is, for example, when the first communication protocol item name is “baud rate”, “baud rate” → “code type” →
"Parity" → "Flow control" → "EXIT"
Are sequentially displayed in this order, and the item contents of these item names are set. Then, the pointer value 3KP is "E
XIT "(S81: Yes),
This control ends, and the process returns to S10 of the setting content setting control.

Next, a description will be given of the setting control of the communication protocol and the like. First, based on the first layer pointer value 1KP and the second layer pointer value 2KP, the third layer pointer value 3KP is set.
The first item number is set in P (S90), and the item name "timeout" of the first item is displayed on the display 10 (S91). Next, substantially in the same manner as in S112 to S118, when the ↓ key 14 is operated (S92 / S9
3: Yes), the third layer pointer value 3KP is incremented by one (S94), and the item name of the next third layer 3K is displayed (S95), and the process returns to S92. In addition, key 13

When the set key 12 is operated (S92: Yes, S93 / S96: No, S99:
Yes), pointer value 3KP is item name "timeout"
(S100: Yes), the setting content, that is, "timeout = tS" is displayed on the display 1.
0 is displayed (S101). Here, t is the timeout time set previously. Next, a setting process for setting the timeout time is executed (S102). That is, in this setting process control, every time the ↓ key 14 is operated, the set time is displayed in increments of one second, such as “0” → “1” → “2” →. Each time the ↑ key 13 is operated, the set time is reduced and displayed in the reverse order. When the set key 12 is operated and the prohibition mode is set, a message “change prohibited” is displayed, When the permission mode is set, the set timeout time t is newly stored.

Next, the item name "RS-232C" is displayed, and the item contents are set for the communication protocol item. The item name of the second layer 2K in the first mode "interface mode" of the first layer 1K is set. "RS-232C"
Therefore, the first mode number is set to the first layer pointer value 1KP and the second item number is set to the second layer pointer value 2KP (S103), and the setting process control of the communication protocol (see FIG. 7) is performed. The control is executed (S104), the control is terminated, and the process returns to S10 of the setting content setting control. On the other hand, when the set key 12 is operated, the pointer value 3KP

This is stored in the predetermined storage area of M28 (S150), and “*” is additionally displayed (S151), and this control is ended and the setting content setting control is ended.

As described above, the lock mode in which the permission mode or the prohibition mode can be set is provided, and the second operation mode such as “Centronics” or “RS-232C” and the item names included in these second operation modes are set. When the setting mode is changed, if the prohibition mode that prohibits the change is set, these settings cannot be changed, so document data and image data are received from an external device and printed. At the time of the receiving operation, the setting data of the setting item is always set to predetermined valid data without being changed by another operator without permission, and the work efficiency of the receiving operation can be improved.

Further, when the setting content of the item name is changed while the prohibition mode is set, a message "change prohibition" notifying that the mode is the prohibition mode is displayed on the display 10, so the user tries to change it. The operator can know the reason why the setting data cannot be changed. In the laser printer P of this embodiment, the lock mode is set by the switch panel SP. However, the lock mode may be set by outputting a command to that effect from an external device.

Note that when the prohibition mode is set, the prohibition target item name whose item contents cannot be changed can be arbitrarily set. Of course, the present invention can be applied to various electronic devices such as a personal computer capable of transmitting document data and image data to an external device. Further, the present invention can be applied to various electronic devices having a plurality of operation modes that do not have a hierarchical structure.
