Description

  The present invention relates to a numerical value setting device that changes a numerical value set for a device when a predetermined operation unit is operated.

Conventionally, in a device such as a copying machine having a copy magnification setting function, for example, when a predetermined operation unit such as an up key or a down key is operated, a function for changing a setting value (copy magnification, etc.) for the device. Some have
Here, for example, in a copying machine, a copy reduction ratio (set numerical value) that can be changed in small increments, for example, in increments of 1% is also provided.
In addition, in devices equipped with such a numerical value setting function, by continuously operating (pressing) the operation unit such as the up key or the down key, the set numerical value is gradually changed and displayed on the display unit. When the set numerical value of the target is displayed, the operation of the operation unit is stopped and the target set numerical value can be changed (changed).
For example, in the setting of the copying magnification (reduction ratio) in a copying machine, if the zoom key (up key or down key) is kept pressed, the copying magnification display is continuously performed at about 10 step changes / second, that is, at intervals of about 0.1 second. Change. However, the change in display of 0.1 seconds is too fast for the operator to be difficult to see. On the other hand, if the change in the copy magnification display is a slow change of, for example, an interval of 0.3 seconds for ease of viewing, there is a problem that the operation must be continued for a long time when the value change width is large. For example, in the example of the copying machine, it takes a long time of 0.3 × (95−70) = 7.5 seconds to change the copying magnification from 70% to 95%.
In order to solve such problems, Patent Document 1 discloses that the speed of the display change of the set numerical value (that is, the change of the value) is determined in advance for a predetermined time after the operation of the operation unit is started. A continuous change that changes in units of the smallest numerical change unit, and then a discontinuous change that changes all or part of the minimum numerical change unit in units of a plurality of minutes. It is shown that the change speed (value change increment) of the numerical display is made faster or the same as that in the middle. As a result, even if the change range of the set value is large, the set value can be changed in a relatively large increment from the middle of the operation, and the target copy magnification can be reached quickly, and the display speed of the copy magnification can be changed. By slowing down, it is possible to ensure the visibility of the copy magnification display.
On the other hand, Patent Document 2 discloses an operation switch device in which an ultrasonic transducer is provided around a push button switch so that a region where the push button switch exists can be distinguished from other regions even if a blind operation is performed. ing.
Japanese Patent No. 2577400 JP 2004-63149 A

However, in a configuration in which the change of the set numerical value is confirmed only by displaying the numerical value, the operator gazes at the display of the set numerical value that changes sequentially for a relatively long time until the set numerical value approaches and reaches the target value. There is a problem that the burden on the eyes of the operator is large. Furthermore, in a portable terminal such as a mobile phone or a portable music player, a problem of safety occurs when walking while staring at a set numerical value, and a problem of deterioration of time efficiency occurs when the user must stop and operate. Such a problem becomes more prominent as the change width (change width) of the set numerical value is larger.
In addition, even the technique disclosed in Patent Document 1 cannot avoid the above-described problem when the change width (change width) of the set numerical value is large.
Further, Patent Document 2 also has a problem that when the set numerical value is changed (changed) in units according to a predetermined rule by continuing to operate the operation unit, the display of the set numerical value must be continuously stared. There is no indication of how to solve.
Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to keep changing the unit according to a predetermined rule by continuously operating the operation unit. It is possible to set the set value to the desired value without continuing to stare at the display of the changing set value. Furthermore, even if the change range (change width) of the set value is large, the set value can be quickly set to the desired value. It is an object of the present invention to provide a numerical value setting device that can do this.

In order to achieve the above object, the present invention is applied to a numerical value setting device that changes a numerical value set for a device when a predetermined operation unit is operated, such as setting of a copying magnification in a copying machine. Yes, while changing the set numerical value in units according to a predetermined rule during the operation of the operation unit (numerical value change control means), while displaying the set numerical value on the display means (numerical value display means), another indicator of the current state of the set number, in which the value of the setting value is configured to notify through one or both of the tactile and auditory thereof that upon reaching a predetermined value is there. Furthermore, the present invention temporarily holds the display of the set numerical value on the display means when a notification is given that the value of the set numerical value has reached a predetermined value (temporary display holding control means). It is comprised as follows.
Thus, in addition to the display of the setting number, other indicators representing the current setting number is informed by tactile and auditory (i.e., are alerted), so the operator the set by the broadcast It is possible to grasp a general situation whether or not the numerical value has approached a desired value (target value), or whether or not the set value has reached a desired value. Accordingly, the monitoring starts when the setting numerical value approaches the desired value by the notification, or when the setting value reaches the desired value, the operation is started. By stopping the operation on the unit, the set value can be set to a desired value without continuously staring at the display of the set value that changes every moment.
Further, in the present invention, when the notification that the value of the set numerical value has reached a predetermined value is made, the display of the set numerical value on the display means is temporarily held. When the display of the set numerical value is confirmed in response to the notification, the value display is fixed (held) without changing, which is preferable for easy viewing.
Further, during a predetermined time after the operation of the operation unit is started, the set numerical value is a continuous change that changes in units of a predetermined minimum numerical value change unit, and thereafter, the set numerical value is completely or partially changed to the minimum value. If it is controlled so that it is a discontinuous change that changes by a plurality of numerical value change units, even if the change range (change width) of the set numerical value is large, it can be set quickly (in a short time) to a desired value. .
Here, as notification through the tactile sensation in the notification means, notification by vibrating the operation unit, etc. can be considered. Similarly, as notification through hearing, a predetermined dial tone or guidance sound (speech of words) is used. notification, etc. think we are.
For example, the pre-Symbol setting numerical outputs only a signal of a predetermined tone to the speaker number of times corresponding to the value every time a predetermined cut good value (10, 20, 30, etc.) (10 "beep" when, at the time of the 20 "beep, beep", ... etc.) and the like can be considered.

Also, in advance from the operator information about the operator of the stored the numerical value setting device in the storage unit, information input through a predetermined input means (password or ID, image information such as operator's face or fingerprints ) Gets the operator information corresponding to, based on the acquired information, the notification is also conceivable to switch whether to perform through either one or both of the tactile and auditory.
Thereby, for example, when the acquired operator information represents an operator who is visually or hearing impaired, the notification can be performed by a method suitable for the operator .
Note that the present invention may be understood as an invention of another category such as a numerical value setting method for changing a numerical value set for a device.

According to the present invention, in addition to display of the setting values for equipment, as another indicator of the current state of the set numerical values, the setting numerical values of the tactile and auditory that became a predetermined value Since the notification is made through one or both , the operator can grasp that the set numerical value has approached or reached the desired value (target value) by the notification, and the setting numerical value that changes every moment can be obtained. The set numerical value can be set to a desired value without continuing to stare at the display. In other words, by performing a notification through the sense of touch and hearing, it said also can be grasped to some extent the state of the setting numerical value by the operation of the blind operation, can mitigate the burden on the operator's eyes. Also in the portable terminal, it is possible to safely perform the numerical value changing operation while walking while not viewing the display of the set numerical value.
Furthermore, when the notification that the value of the set numerical value has become a predetermined value is made, the display of the set numerical value on the display means is temporarily held. When the display of the set numerical value is confirmed in response, the value display is fixed (maintained) without changing, which is preferable for easy viewing.
Further, during a predetermined time after the operation of the operation unit is started, the set numerical value is a continuous change that changes in units of a predetermined minimum numerical value change unit, and thereafter, the set numerical value is completely or partially changed to the minimum value. If it is controlled so that it is a discontinuous change that changes by a plurality of numerical value change units, even if the change range (change width) of the set numerical value is large, it can be set quickly (in a short time) to a desired value. .
Further, acquires operator information corresponding to the information input through a predetermined input means, based on the acquired information, the notification, be switched or performed through either one or both of the tactile and auditory Since the notification can be performed by a method suitable for the operator, the operability is further improved.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that the present invention can be understood. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.
FIG. 1 is a block diagram showing a schematic configuration of a main part of a copying machine Z provided with a numerical value setting device X according to an embodiment of the present invention, and FIG. 2 is displayed on a display operation unit provided in the numerical value setting device X. FIG. 3 is a flowchart showing an example of the procedure of setting numerical value change processing in the numerical value setting device X. FIG.

First, with reference to the block diagram shown in FIG. 1, the configuration of the main part of a copying machine Z, which is an example of a numerical value setting device X according to an embodiment of the present invention and a device on which the numerical value setting device X is mounted, will be described.
The copying machine Z includes a document reading unit 1, an image processing unit 2, an image forming unit 3, a copy magnification control unit 4, a numerical value setting device X, and the like. In addition, various components included in a normal copying machine are also provided.
The document reading unit 1 includes various optical systems and CCD elements, and reads an image from a document placed on a document table.
The image processing unit 2 includes an image memory (not shown), and performs various types of image processing on the document image read by the document reading unit 1.
The image forming unit 3 includes a photosensitive drum and its peripheral devices (charging device, developing device, transfer device, cleaning device, etc.), a laser scanner device for writing an electrostatic latent image on the photosensitive drum, and the like. The image read by the section 1 and subjected to the image processing by the image processing section 2 is formed on a recording sheet.
The copy magnification control unit 4 performs the position control of an optical system such as a lens and the movement speed control of an exposure lamp that exposes a document according to the value of the copy magnification set by a numerical value setting device X described later. The image forming unit 3 controls the reduction ratio of the image formed on the recording sheet.

Also, the numerical value setting device X according to the embodiment of the present invention is a value such as a copy magnification which is a numerical value set for the copying machine Z (equipment) in which the numerical value setting device X is mounted when a predetermined operation unit is operated. Is changed (set).
Here, the numerical value setting device X includes a peripheral device such as a ROM in which an MPU and a program executed by the MPU are stored, a control unit 10 for controlling each component of the copying machine Z, and the copying magnification. A display means (an example of a numerical value display means) such as a liquid crystal panel for displaying set numerical values and other information, etc., and a touch sensor is formed on the surface of the display portion, and an operation button is displayed on the display portion. A display operation unit 11 that functions as a display operation unit, a vibration generation unit 12 that transmits vibration to the finger of an operator who is operating the display operation unit 11 by generating vibrations in the display operation unit 11, and a dial tone through a speaker. The data output which is a non-volatile storage means such as an EEPROM for storing various kinds of information such as a voice output unit 13 for output and a set numerical value set by the numerical value setting device X The user authentication process is performed based on input information such as the user ID (or password) input by the operator from the display unit 14 and the display operation unit 11 and the fingerprint image of the operator captured by a fingerprint imaging device (not shown). In addition, when the user authentication is established, the user authentication unit 15 that reads and acquires the operator information related to the operator (user) corresponding to the input information from the authentication information storage unit 16 described later, and the operation of the numerical value setting device X Information storage unit which is nonvolatile storage means such as a hard disk for storing operator information related to an operator who is permitted to use, user authentication information of the operator (ID, password, fingerprint image, etc.) and information related to each operator 16. Of course, it is also conceivable that the storage means corresponding to the authentication information storage unit 16 is provided in an external device (server computer or the like) connected via a network or the like.
The vibration generating unit 12 may be an unbalanced mass type vibration generating means that rotates by attaching an eccentric mass (weight) to the motor, and generates a vibration by centrifugal force. It is conceivable to use electrodynamic vibration generating means or the like based on the same principle as that of a speaker using the force generated by.
Here, only when the user authentication is established (successful) by the user authentication unit 15, the control unit 10 performs all of the numerical value setting device X (that is, the copier Z) through the display operation unit 11. When a processing request (copy processing request) is received and user authentication is not established, control is performed such as prohibiting reception of some or all processing requests.

Next, an example of a procedure for setting numerical value change processing in the numerical value setting device X will be described using the flowchart shown in FIG. S1, S2,... Shown below represent identification codes of processing procedures (steps). Further, the processing of the control unit 10 and the user authentication unit 15 described below is implemented by executing a predetermined control program or user authentication program by an MPU included therein.
First, input information such as a user ID and a password input by an operator through the display operation unit 11 by the user authentication unit 15 or a fingerprint photographed by a fingerprint photographing device connected to the user authentication unit 15. Based on image information or the like (hereinafter referred to as authentication input information), user authentication is performed as to whether or not the operator is permitted to operate the numerical value setting device X. If the user authentication is successful, The operator information corresponding to the authentication input information is acquired by reading out the operator information related to the operator of the numerical value setting device X stored in advance in the authentication information storage unit 16 (S1, operation Example of person information acquisition means).
Here, the operator information includes, for example, information regarding whether or not the operator has a visual impairment and whether or not the operator has a hearing impairment.
Next, the control unit 10 ends the process when the user authentication fails (N side of S2), but when the user authentication is successful (Y side of S2), the display operation unit 11 From step S3, it is determined whether an operation requesting a change in the setting value such as the copying magnification or the like or an operation requesting other processing has been performed (S3). The process shifts to another process execution mode (N side of S3).
On the other hand, when the control unit 10 determines that a setting value change request operation such as the copy magnification has been performed (Y side of S3), the control unit 10 displays a setting value change screen (numerical value setting screen) in the display operation unit. 11 is displayed (S4). At that time, the current copy magnification (set numerical value) is read from the data storage unit 14 and the value is also displayed.
FIG. 2 is an example of a numerical value setting screen that is displayed on the display operation unit 11 by the control unit 10 when an operation requesting the change processing of the copy magnification is performed.
In this numerical value setting screen, for example, as shown in FIG. 2, there are an up button 21 which is an operation unit for changing the copying magnification (setting numerical value) in the increasing direction and an operating unit for changing in the decreasing direction. A down button 22, a numerical value display unit 20 for displaying the current copy magnification (setting numerical value), and a return button 23 that is an operation unit for ending the numerical value setting process are displayed.

Next, the control unit 10 is a numerical value representing the current state of the copying magnification (setting numerical value) based on the operator information acquired by the user authentication unit 15 (an example of operator information acquisition means) in step S1. An indicator other than the display (hereinafter referred to as a current indicator) is notified through the tactile sensation of the operator who operates the display operation unit 1 by vibrating the vibration generating unit 12, and the voice output unit 13 performs a predetermined operation. Any one of the notification 3 through the auditory sense of the operator by outputting a dial tone and a guidance sound, and the notification through the visual sense by changing the display pattern of the numerical display of the copy magnification by the display operation unit 11 A notification method indicating whether to perform one or a plurality of combinations is switched (an example of a notification control unit).
For example, if the operator information includes information indicating that the operator is a person with hearing impairment, the method A for performing notification through “visual and tactile sensation” is used to indicate that the operator has a visual impairment. If the information is included, the method B for performing notification through “auditory and tactile sensation” is used, and in the other cases (default), the method for performing notification through “visual, auditory, and tactile” is employed.
Next, the control unit 10 checks whether or not the up button 21 or the down button 22 (an example of the operation unit) in the display operation unit 11 is operated (ON) (S6). When the operation is continued (ON), the processing of this step S6 and the following steps S7 to S16 is performed at a predetermined cycle (for example, a cycle of 0.1 seconds) while the operation is continued (the pressing operation of the same button is continued). Repeated sequentially.

First, in step S7, the control unit 10 adds a predetermined step value D to the current copy magnification (set numerical value) read from the data storage unit 14 (when the up button 21 is being operated) or The subtraction (when the down button 22 is being operated) is updated by being stored in the data storage unit 14 (S7). The initial value of the step value D is a minimum numerical value change unit (here, 1 (%)) predetermined for the copying magnification (set numerical value).
Further, the control unit 10 sets a change value (absolute value of difference) W of the copy magnification (set numerical value) after the button operation is started (that is, adds the step value D to the current change value W). (S8). The initial value of the change value W is 0 (zero).
Although not shown in this flowchart, the step value D and the change value W are initialized when the continuous operation (continuing pressing) of either the up button 21 or the down button 22 is interrupted. (D ← 1, W ← 0).
Next, the control unit 10 performs a setting (re-setting) process of the step value D (S9). For example, when the change value W is less than a predetermined first set change value H1 (for example, 5), the step value D remains the initial value (= 1), the change value W is equal to or higher than H1 and the first change value W1. When the set change value H2 is less than 2 (for example, 40), the step value D is set to the first step value (= 5), and when the change value W is H2 or more, the step value D is set to the second step value. Setting to a value (= 10) can be considered.

Next, the control unit 10 determines whether or not the change value W has reached any of a plurality of predetermined values (default values) (S10), and has not reached the default value. In this case, the process proceeds to step S13 described later. If the predetermined value has been reached, the process proceeds to step S11 and the notification method set in step S5 (any one of A to C). To that effect.
Here, as the default value, for example, “10, 20, 30,...” (Numerical value obtained by rounding one or more lower digits) or “50, 100, 150,. It may be possible to do so.
For example, in the notification method A, the display pattern of the numerical display unit 20 in the display operation unit 11 is changed (for example, reverse display or color change display is performed), and the display operation unit is operated by the vibration generation unit 12. 11 panel (operation part) is vibrated temporarily.
In the notification method B, the voice output unit 12 outputs a predetermined dial tone “beep” through a speaker, and the vibration generator 12 temporarily opens the panel (operation unit) of the display operation unit 11. Vibrate.
Further, in the notification method C, the display pattern change of the numerical value display unit 20, the dial tone output by the voice output unit 12, and the vibration of the display operation unit 11 by the vibration generation unit 12 are performed.
Further, the control unit 10 allows the display operation unit 11 (numerical value display means) to set the copy magnification (set numerical value) for a time sufficient to visually confirm the copy magnification value display after the operator notices the notification. ) Is temporarily held (S12), and the process proceeds to step S13. As a result, when it is informed in step S11 that the change value of the copy magnification has reached the predetermined value, the display operation unit 11 (numerical value display) regardless of the change after the copy magnification (set numerical value). The display of the copying magnification (setting numerical value) by means) is temporarily held. Hereinafter, the setting in step S12 is referred to as display hold setting. In addition, reaching the default value means that the value is equal to or higher than the default value when the up button 21 is operated, and the value is equal to or lower than the default value when the down button 22 is operated.

In step S13, the control unit 10 determines whether or not the display holding setting is made. If it is determined that the setting is not made, the new copying magnification (setting) updated in step S7 is determined. (Numerical value) is updated and displayed on the numerical value display unit 20 of the display operation unit 11 (S15), and then the process proceeds to step S16.
On the other hand, when it is determined that the display holding setting is made, the control unit 10 displays the display of the copying magnification (setting numerical value) regardless of the change of the copying magnification (setting numerical value) in step S7. After the display holding setting is canceled while the display on the operation unit 11 is temporarily held as it is (S14), the process proceeds to step S16. This canceling process is canceled until a predetermined holding time (specifically, managed by the number of repetitions of the processes in steps S6 to S16) elapses after the display holding setting is made in step S12. In this process, the display holding setting is canceled when it is determined that the holding time has passed and the holding time has elapsed. The display hold setting is also released when the continuation operation (holding down) of either the up button 21 or the down button 22 is interrupted.
In step S <b> 16, the control unit 10 determines whether or not a predetermined end operation (specifically, operation of the return button 23) has been performed from the display operation unit 11, and a state in which no operation is performed for a predetermined time or more. It is determined whether or not an end condition of the set numerical value changing process (numerical value setting process) is satisfied depending on whether or not the process is continued. If it is determined that the end condition is not satisfied, the process returns to step S6 described above. Thereby, the process of step S6-S16 mentioned above is repeated with a predetermined period. On the other hand, when it is determined that the end condition is satisfied, the control unit 10 ends the set numerical value changing process (numerical value setting process).

As described above, the control unit 10 determines the copy magnification (set numerical value) in advance while the operation of the up button 21 or the down button 22 (operation unit) is continued by the processing of steps S7 and S9. The unit is changed by one unit (1 unit, 5 units, or 10 units) according to the rule (an example of numerical value change control means).
Specifically, the control unit 10 determines the copy magnification during a predetermined time after the operation of the operation units 21 and 22 is started (a time during which the change value W is less than the first set change value H1). Is a continuous change that changes by a predetermined minimum numerical change unit (the initial value (for example, 1) of the step value D), and the copying magnification is set to the minimum numerical change unit for all subsequent time zones (all). Are controlled so as to be discontinuous changes that are changed by a plurality of minutes (for example, 5 or 10) (an example of numerical change control means).
For example, when the continuous operation of the up button 21 (continuation of the pressing operation) is performed when the originally set copy magnification value is 70 (%), a predetermined cycle (for example, 0.1 second) ), The value of the copying magnification changes as 70, 71, 72,... 75, 80, 85, 90,..., 105, 110, 120, 130,.
As a result, the target copying magnification can be quickly reached.
The display of the value of the copying magnification on the display / operation unit 11 is normally updated according to the change of the value, but when the value reaches a predetermined value (for example, 100, 150, etc.) When the notification is issued), the value display is temporarily held (for example, about 0.5 seconds).
Thus, when the operator recognizes the notification that the copy magnification has reached the predetermined value, the operator can easily confirm the content of the notification (the state of the copy magnification).
It is also conceivable that after a predetermined time has elapsed after the start of the investigation, the copy magnification is partially controlled to be a discontinuous change in which the minimum value change unit is changed by a plurality of minutes. For example, when the copy magnification (set numerical value) approaches a lower limit value or an upper limit value, the value of the copy magnification is changed by a minimum unit (for example, 1) while the operation of the operation units 21 and 22 is continued. Etc. are considered.

  Further, in step S11, the fact that the change value of the copy magnification has reached a predetermined value as the current index other than displaying the copy magnification (set numerical value) on the display / operation unit 11 is determined as the vibration. Since the generation unit 12 gives notification through touch, the voice output unit 13 gives notification through hearing, and the display operation unit 11 gives notification through vision (both are examples of notification means). It is possible to grasp whether the magnification has approached the desired value or whether the desired value has been reached. Accordingly, when it is grasped that the copy magnification has approached a desired value by the notification, monitoring (gazing) of the numerical display of the display operation unit 11 is started, or when it is grasped that the desired value is reached. By stopping the operation of the operation units 21 and 22, it is not necessary to keep staring at the display of the copy magnification that changes every moment.

Here, in the above-described embodiment, an example in which the change value of the copy magnification has reached a predetermined value is shown as the current index, but the present invention is not limited to this.
For example, it is conceivable to notify the value of the copying magnification (setting numerical value) or the magnitude of the change value as the current index.
For example, according to the value of the copy magnification or the change value thereof, the set frequency of the oscillator and the supply current value in the vibration generating unit 12 are controlled to change the vibration frequency and the vibration intensity (amplitude) so as to change the tactile sensation. Changing the tone, changing the tone (frequency) of the dial tone by controlling the voice output unit 13, and changing the brightness, color, or blinking cycle of the backlight by controlling the display operation unit 11. Etc. are considered.
Further, as the current index, it may be possible to notify that the value of the copy magnification (set numerical value) itself has reached a predetermined value (default value).
For example, the copy magnification is 70 (%), 81 (%), 115 (%), 122 (%), 141 (%), etc., standard size of recording paper (A3, A4, A5, B4, B5, etc.) Whenever the copy magnification (default value) for size conversion between each other is reached, vibration is generated by the vibration generating unit 12, a dial tone or voice guidance by the voice output unit 13 (sound that reads out the value at that time, etc.) ), And blinking of the backlight of the display operation unit 11 (an example of changing the display pattern).
Further, as the current index, it is also possible to notify that the unit for changing the copy magnification (set numerical value) has been changed by the processes of steps S7 and S9 (an example of the process of the numerical value change control means) by the control unit 10. It is done.
For example, when the step value D changes from 1 to 5 or from 5 to 10, the generation of vibration by the vibration generation unit 12, the output of a dial tone or voice guidance by the voice output unit 13, the display operation It is conceivable to perform flashing of the backlight of the unit 11 (an example of changing the display pattern).
It is also conceivable to notify by combining a plurality of the above-mentioned current indicators.
For example, in addition to changing the vibration frequency of the vibration generating unit 12 in accordance with the value of the copy magnification or the change value thereof (the higher the value, the higher the frequency, etc.), the copy magnification is a predetermined value. The intensity of vibration is temporarily increased every time the signal reaches, or the pitch (frequency) of the dial tone by the audio output unit 13 is changed according to the value of the copy magnification or the value of the change. In addition, every time the copying magnification reaches a predetermined value, a voice guidance that reads the reached default value may be output.

In the above-described embodiment, the display operation unit 11 (numerical value) is notified when it is notified that the change value W of the copy magnification has reached a predetermined value by the processing of steps S12 to S15 by the control unit 10. In the above example, the display of the copy magnification (set numerical value) by the display means is temporarily held, but a notification that the copy magnification value itself has reached a predetermined value by the same processing of the control unit 10 has been shown. In addition, when the notification of the change of the unit for changing the copying magnification is made by the processing of the steps S7 and S9 by the control unit 10 (an example of the processing of the numerical change control means), It is also conceivable that the display of the copy magnification (set numerical value) by the display operation unit 11 (numerical value display means) is temporarily held (an example of a temporary display holding control means).
Further, as a notification means through tactile sense, in addition to the notification by vibration, for example, a notification means by causing a weak electric signal (for example, a low-frequency current) to flow through the operation unit to feel an electric tactile sensation, etc. Conceivable.
Further, as a means for visually informing, it is conceivable to provide a separate lamp for the notification in addition to changing the display pattern of the set numerical values.
In the embodiment described above, the copying magnification (reduction ratio) value of the copying machine has been described as an example of the setting numerical value. However, the numerical setting device according to the present invention is used in an image processing apparatus such as a copying machine. It is obvious that the method can be applied when changing (setting) other various setting numerical values or when other numerical values such as audio equipment are required.

  The present invention can be used for a numerical value setting device.
