Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of the conventional erroneous operation prevention mode which does not allow key entry unless keys are surely operated twice or unless they are pressed for a long time, and which is not required by everyone although it reduces erroneous operation. <P>SOLUTION: Only when it is determined during operation in an ordinary mode that the image forming apparatus is used by a user who misoperates keys many times, the mode is switched to the erroneous operation prevention mode. Therefore, a user who makes very few mistakes in key operation can use the ordinary mode whereas a user who makes many mistakes in key operation can use the erroneous prevention mode, thereby solving the problem. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image forming apparatus having a copy function, such as a digital copying machine, a facsimile machine, and a composite apparatus, and more particularly, to an image forming apparatus having an erroneous operation prevention mode that reduces a key operation mistake on a display screen for performing job setting.
[0002]
[Prior art]
In recent years, office devices such as copiers, scanners, facsimiles, and printers have become multifunctional, high-speed, and low-priced as stand-alone dedicated machines, but complex devices that combine these functions into one are common. It's becoming a reality. Also, the content of the job is enriched as a single copying machine, and it is obvious that image rotation processing, frame removal, 2 in 1 output, 4 in 1 output, overlay such as “secret” and “important”, and slip sheet mode can be performed. Further, some of these composite devices have a simple bookbinding function by attaching a post-processing device as an option so that punched holes can be made in the printed matter or stapling can be performed.
[0003]
As another scanner function, it is also possible to send an image to a designated personal computer via a network line. Facsimiles and printers can be used in the same way as before, and of course the above-described processing can be performed for facsimiles and printer output. As described above, in recent complex apparatuses, complicated job setting by a user has become possible.
[0004]
As described above, in an image forming apparatus such as a composite apparatus having various functions, complicated settings can be made. However, since the number of operation keys per screen of the LCD display section has increased considerably, an operation error has occurred. Key entry may be made. Therefore, there are an erroneous operation prevention mode in which the key is entered by operating the same key twice in succession, an erroneous operation prevention mode in which the key is entered only when operated for a predetermined time or longer (see, for example, Patent Document 1).
[0005]

[0030]
The processing of the present invention will be described with reference to the flowchart of FIG. First, the key displayed on the operation display unit is operated once to start from the normal mode in which the key is entered (S101), and it is determined whether or not there is an operation (S102). If the key displayed on the operation display unit is operated (S103), the key operation is entered (S104), the miscount n is cleared, and the key displayed on the operation display unit is cleared. The processing ends after selection of the function corresponding to the key or screen switching.
[0031]
If it is determined in S103 that the key displayed on the operation display unit has not been operated, that is, an area other than the key on the operation display unit has been operated, miscount n = n + 1 is set (S106). It is determined whether n is a predetermined number N or more (S107). If the miscount n is not greater than or equal to the predetermined number N, the process returns to S101. If the miscount n is greater than or equal to the predetermined number N, that is, if it is determined that there are many erroneous operations, for example, as shown in FIG. As shown in FIG. 8, a pop-up message indicating that the operation display unit is switched to the erroneous operation prevention mode is displayed (S108), and “black operation display” is displayed on the black belt display unit, which is displayed on the operation display unit of the first invention of the present application. Only when the same key is operated twice in succession to prevent accidental operation, where the key is entered, or when the key displayed on the operation display section of the second invention of the present application is operated for a predetermined time or more. The operation mode is switched to the erroneous operation prevention mode in which the key is entered (S109). Furthermore, the settings of the third invention of the present application that have been input by the key are cleared (S110). Here, since S108 and S110 are not essential, it is sufficient to design whether the processing includes S108 and S110 or not.
[0032]
According to the above flow, an example of a case where a user with many key operation mistakes uses will be described with reference to FIG. Here, the predetermined number N is twice. First, the operation is started in the normal mode (S101), and an attempt is made to operate the key of the operation display unit. However, if only the area without the key is touched, the process proceeds from S102 to S103 to S106, and in S106, n = 1. Subsequently, in S107, since n = 1, N = 2 and n ≧ N is not satisfied, the process returns to S101. If an attempt is made again to operate the key on the operation display unit or if the operation fails, the process proceeds from S102 to S103 to S106, and in S106, n = 2. Subsequently, in S107, n = 2, N = 2, and n ≧ N is satisfied, and the process proceeds to S108. The operation display unit displays that the operation mode is switched to the erroneous operation prevention mode (S109). The settings are cleared (S110).
[0033]
Next, a flow up to entry of key operation in the erroneous operation prevention mode in the first invention of the present application will be described with reference to FIG. First, in the erroneous operation prevention mode, when the key is operated, it is determined whether or not the key is on edge (S201). If the key is on edge, the timer t1 for measuring the time from the first key operation is cleared and started. (S202). Subsequently, the time from the first key operation to the second key operation is compared with T1 which is the time limit (S203). When t1 ≧ T1, that is, from the first key operation to the next operation. If the time is more than T1, the process returns to S201. If t1 ≧ T1, it is determined whether or not the next key operation is on-edge (S204). If the key operation is on-edge, it is determined whether this key operation and the previous key operation are the same key (S205). If they are the same, this key operation is entered (S206), the corresponding function selection or screen switching is performed, and the process is terminated. If it is determined in S206 that it is not the same as the previous key operation, the key operation returns to S202. As described above, since key entry is not performed unless the key operation is performed twice in succession, erroneous operation is prevented.
[0034]
The flow up to the key operation entry in the erroneous operation prevention mode in the second invention of the present application will be described with reference to FIG. First, in the erroneous operation prevention mode, when the key is operated, it is determined whether or not the key is on edge (S301). If the key is on edge, the timer t2 for measuring the time since the key is pressed is cleared and started ( S302). Subsequently, t2 is compared with T2, which is a time during which the key needs to be kept pressed for a minimum (S303). If t2 ≧ T2, the process returns to S301. If t2 ≧ T2, that is, the key is pressed more than T2. In this case, this key operation is entered (S304), the corresponding function selection or screen switching is performed, and the process is terminated. If the key is not on edge in S301, it is determined whether or not the key is on (S306). If the key is not on, the process returns to S301. If the key is on, the process proceeds to S303. As described above, since the key operation is not entered unless the key operation is kept pressed for a predetermined time or longer, the key entry is not performed when the key is inadvertently touched.
[0035]
【The invention's effect】
If the first and second inventions of the present application are used, it is determined that the operation of the area other than the key of the operation display unit is an operation error. Key entry in the normal mode can be performed on a screen with few users or few mistakes, and an erroneous operation prevention mode is set on a user with many mistakes or a screen with many mistakes, thereby reducing subsequent mistakes.
[0036]
If the third invention of the present application is used, if there are many erroneous operations, it is doubtful whether the settings that have been input so far are correct or not, so the input so far is cleared at the timing of switching from the normal mode to the erroneous operation prevention mode.
[0037]
According to the fourth aspect of the present invention, by notifying the user when switching from the normal mode to the erroneous operation prevention mode, it is possible to know that the subsequent key input method needs to be operated by pressing twice or long.
[0038]
If the fifth invention of the present application is used, the operation is switched from the erroneous operation prevention mode to the normal mode as the job ends, so that the user also changes when the job ends, so that the next user can start from the key operation in the normal mode.
