Description

Description: BACKGROUND OF THE INVENTION The present invention relates to setting of an image forming mode.

[Prior Art] In a copying machine or the like, a more sophisticated device is desired by adding a function which is considered to be convenient for an operator. However, the operation becomes complicated with an increase in the added function. In order to perform a desired operation, a complicated operation must be performed.

[Purpose] The present invention has been made in view of the above points, and has as its object to provide an image forming apparatus capable of reading out parameters of an image forming mode used in past image forming for each parameter type. Things.

That is, the present invention provides a key input unit for setting a plurality of types of parameters relating to an image forming mode, a first input unit for inputting a start command of an image forming operation, and a plurality of times from the first input unit. Storage means for storing, for each type of the parameter, a value of a parameter relating to an image forming mode of a plurality of times of image formation executed by the start command,
A plurality of second input means for inputting a read command for independently reading the value of the parameter stored in the storage means for each type of the parameter; and each time a start command is input by the first input means, Comparing the values of the plurality of types of parameters set by the key input means with the values of the parameters already stored in the storage means for each parameter type, and storing the values of the matching parameters in the storage means. Instead, the values of the parameters that do not match are stored in the storage means, and each time a read command for a desired type of parameter is input from the second input means, the desired type of the desired type is read from the storage means. Control means for cyclically reading parameter values and setting the image forming mode.

Then they can be called independently and set to 106.

FIG. 3 is a plan view of the device in this embodiment. 201,
202, 203, and 204 are the same as those described above with reference to FIGS. 2-1 and 2-2, and a description thereof will be omitted.

A copy start key 301 starts a copy operation with this key. A reset / stop key 302 is used for initializing a mode and interrupting a copy operation. Reference numeral 303 denotes a numeric keypad group for setting the number of sheets, and the set number is displayed on the number display LED 304.

305, 306, 307 are key groups related to paper selection,

Reference numeral 307 denotes a recall key related to paper selection, which is used to call a paper selection mode selected in the past.

Reference numerals 308, 309, 310, 311, 312 denote keys and display groups related to copy density, 308 and 309 denote keys for adjusting copy density, and 310 denotes an LED display for displaying a designated density level. Reference numeral 311 denotes a key for instructing automatic density adjustment. Three
Reference numeral 12 denotes a recall key for the copy density, which is used to call up the copy density selected in the past.

313, 314, 315, 316, 317, 318, 319 are keys related to scaling, 313 is a key used to specify scaling between fixed sizes such as A3 to A4, and 314 is A4
This key is used to specify the scaling between fixed sizes such as to A3. The zoom keys 115 and 116 are used to increase or decrease the magnification in increments of 1%, respectively. Reference numeral 317 is used to specify the same size copy with the same size key. Reference numeral 318 is used to automatically calculate a scaling ratio using an auto scaling key. Reference numeral 319 denotes a recall key for scaling, which is used to call a mode for scaling selected in the past.

Reference numeral 319 denotes a message display using liquid crystal, which displays the selected mode, other warnings, and operation instructions.

320, 321, 323, and 324 are key groups related to area designation.
For example, two points 325 and 326 in FIG.
, And when the trim key is pressed, 2 points 325
Only the rectangular area having the diagonal points 326 and 326 is copied, and the other parts are cut. Similarly, when the mask designation key is pressed after the two points 325 and 326 are designated by the touch pen 203, only the area excluding the rectangular area having the two points 325 and 326 as diagonal points is copied. A clear key 323 for specifying an area is used to release the specified area. A recall key 324 is used to recall a previously specified area.

FIG. 4 is a flowchart for storing and recalling operation modes. Reference numerals 401 to 411 indicate steps, and N indicates the number of modes that can be stored in the operation mode storage means 113, 114, 115, 116. i is a value of a counter (not shown) and takes a value of 0 to N−1, becomes address information of the mode storage means 113, 114, 115, and 116, and takes an independent flow for each function.

When the power is turned on, the flow starts. First, it is determined whether the copy key 301 has been pressed (step 40).
1) In the case of YES, the copying operation is executed, and it is determined whether or not the current copy mode matches the operation mode stored in the previous operation mode storage means 112 (step 402). If NO, the count value i is incremented by one (step 403), and it is determined whether the count value i is equal to or greater than the maximum number N (step 403).
404), if NO, proceed to step 406 and thereafter, and if YES, clear the count value i to "0" (step 405). Next, the currently set operation mode is stored in the memory area of the operation mode storage means 112 designated by the count value i (step 406), and the process returns to step 401.

On the other hand, if the determination in step 401 is NO, it is determined whether the recall key has been pressed to read the operation mode stored in each operation mode storage unit 112 (step 407). Return, and if YES, decrement the count value i by one (step 40).
8) It is determined whether or not the count value i is equal to or greater than "0" (step 409). If YES, the process proceeds to step 411, and if NO, the maximum number N is substituted into the count value i (step 41).
0). Next, the operation mode stored in the memory area of the operation mode storage means 5 designated by the count value i is read out (step 411), and the process returns to step 401.

Thus, each time the copy start key 301 is pressed, only the operation mode that is currently set in each function is different from the already registered operation mode, and only the operation mode that is already registered is sequentially stored, and each time the recall key is pressed, Independently for each function, it can be read out cyclically from the newly stored operation mode sequentially.

[Effects] As described above, according to the present invention, previously used parameter values can be easily read for each type of image forming mode parameter, and image forming mode in which the previously used image forming mode is partially changed The mode can be easily set.

Further, since the same value as the parameter value of the image forming mode that has already been stored is not newly stored, the memory can be used efficiently.
