Abstract

PURPOSE:To form an image processing unit with which a fine magnification setting operation can be efficiently made by constituting the unit in such a manner that the divided transfer magnification region divided to plural transfer magnifications can be set to a prescribed movable region. CONSTITUTION:The operator pushes down a reduction magnification selector key 12 when the operator desired to take a copy at, for example, 70% reduction. A reduction magnification region display device 11a is then lighted up and the magnification can be continuously set in a 60%-100% reduction range. The operator operates a variable volume control 5 and sets the same at 70% after said setting, by which the magnification setting operation is finished. The operator pushes down first an enlargement magnification selector key 13 when the operator desires to take a copy at 120% enlargement. An enlargement magnification region display device 11b is lighted up and the magnification can be continuously set in a 100%-140% enlargement range. The operator operates the volume control 5 and sets the same at 120% after said setting, by which the magnification setting operation is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing apparatus that can set a plurality of magnification ranges using the same magnification setting means.

[Prior art and its problems]

Conventionally, this type of apparatus has been configured so that settings from reduction to enlargement can be made continuously using a single magnification setting lever. With this method, you can set the desired magnification simply by moving the magnification setting lever, but when the range in which the magnification can be set becomes wide, the movable range of the magnification setting lever is constant, so if you want to finely set the magnification within a specific range, The disadvantages are that the magnification setting lever is difficult to operate and the magnification setting operation is very time-consuming.

[Purpose of the invention]

This invention has been made in order to eliminate the above-mentioned drawbacks, and is configured such that a divided transfer magnification area, in which the transfer magnification is divided into a plurality of areas, can be set in a predetermined movable area, and detailed magnification setting operations can be performed efficiently. The purpose is to provide an image processing device.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention.
1 is a one-chip microcomputer (hereinafter referred to as MC) having an analog input section, such as fiLCOM87.
AI) (product name: manufactured by NEC Corporation) is used. Reference numeral 2 denotes an operation board, 3 a display section composed of an LED matrix, and 4 an operation mode setting means composed of a key matrix, through which the number of copies, transfer magnification, etc. are set. 5 is a variable volume for setting the transfer magnification, and is connected to the analog input section of the MCI. 6 is a variable volume for setting the transfer density, and is connected to the analog input section of the MCI.

FIG. 2 is an enlarged plan view of the main parts of the operation board 2, where 5 indicates the same thing as in FIG. It's getting better. The enlargement magnification area display 11a displays reduction magnifications ranging from 60% to 100%, for example. The magnification area display 11b displays magnifications ranging from 100% to 140%, for example. Furthermore, an LED or liquid crystal is used for this display. 12 is a reduction magnification selection key corresponding to the magnification area setting means of the present invention;
00%) is set.

Reference numeral 13 is an enlargement magnification selection key corresponding to the magnification area setting means of the present invention, which selects a divided transfer magnification area (100% to 15%).
0%) is set. 14 is a numeric keypad for setting the number of transfer sheets, a part of which is shown.

Next, the operation will be explained.

When the power is turned on, the transfer magnification is automatically set to the same magnification (100%), and the reduced magnification area display 11a of the magnification area display section 11 is displayed.
, the magnification area display 11b is off.

If the operator wishes to make a copy with a reduction ratio of 70%, he or she first presses the reduction ratio selection key 12. As a result, the reduction magnification area indicator 11a lights up, and the reduction magnification is 6'0.
The magnification can be set continuously in the range of % to 100%. Thereafter, while viewing the display on the reduction magnification area display 11a, the variable volume 5 is operated to adjust to 70%, thereby completing the magnification setting operation.

Further, if the operator wants to make a copy at a magnification of 120%, he or she first presses the magnification selection key 13. As a result, the magnification area indicator 11b lights up, and the magnification can be set continuously in the range of 100% to 140%. Thereafter, while viewing the display on the magnification area display 11b, the variable volume 5 is operated to adjust to 120%, thereby completing the magnification setting operation. Since the enlargement or reduction magnification area can be set in the movable area of the variable volume 5 in this way, it is possible to set the magnification more precisely than in the past.

FIGS. 3(a), 3(b), and 3(C) are flowcharts illustrating the control operation of the present invention. In addition, (1) to (3)
, (11)-(13), (21)-(23)
represents each step.

The flow shown in FIG. 3(a) starts when the reduction magnification selection key 12 is pressed. First, the reduction magnification area display 11a is turned on (1), and the lower limit value Y of the magnification setting area is set to "
60” (2). Next, variable volume 5
The sample is started and the control is ended (3).

The flow shown in FIG. 3(b) starts when the magnification selection key 13 is pressed. First, the magnification area display 11b is turned on (11), and the lower limit Yr of the magnification setting area is set.
Set to lOOJ (12). Next, sampling of the variable volume 5 is started and control is ended (13).

The flow shown in FIG. 3(c) starts with an interrupt signal sent by the MCI every romsec, and the variable volume 5
The sampling value x1 designated by is divided into 41 and converted to actual measurement data. Therefore, the sampling value X□ is divided by 6.2, which is 256 divided by 41) (
22), Then, the lower limit value Y obtained in step (2) or (12) and the converted value X obtained in step (22) are added to determine the magnification value, and the control is ended (23) .

Specifically, for example, when the operator presses the enlargement magnification selection key 13, the flow shown in FIG. 3(b) is executed, the lower limit value Y is set to 100, and the variable volume 5, and if the sampling value x1 at this time is, for example, 200, the MCI calculates the converted value X (200/6, 2), and this calculated value 3
The value obtained by adding the lower limit value y (too) to 2゜26 is the magnification value (
132%).

〔Effect of the invention〕

As explained above, the present invention is provided with a magnification area setting means for setting one of the arbitrary divided transfer magnification areas into a plurality of divided transfer magnification areas as a movable area, so that the unit movement amount of the magnification area setting means is Since the magnification can be set larger than conventional magnification, detailed magnification setting operations are possible. Furthermore, since it can be easily constructed using the same magnification setting means, it has the advantage of reducing the cost of the apparatus.
