Embodiment 1

[0053] First, the first embodiment will be described. In this embodiment, in the paper feeding simulation, the conditions for occurrence of a paper jam are set in advance, and when the set conditions are reached, the conveyance of the virtual paper is stopped and a paper jam is generated. Here, the word "virtual" is used because it means an imaginary paper in the simulation.

[0054] figure 1 A design support device according to the present embodiment is shown. The design support device of this embodiment is a paper feed simulator capable of performing paper feed simulation of an image forming apparatus on a personal computer. In addition, it supports control timing design of firmware software for controlling an imaging device in the real world, and can verify the processing operation of the firmware software.

[0055] The software emulation section 1 is a section for virtually executing firmware software related to paper feed control on a personal computer. The input moni...

Embodiment 2

[0092] Next, a second embodiment will be described. In this embodiment, conditions for occurrence of a paper jam are set in advance, and when a paper jam occurs when the set conditions are satisfied, a warning message that a paper jam occurs is displayed.

[0093] FIG. 10 shows a software simulation section 1 and a mechanism simulation section 2 of the design support device in the second embodiment. The same figures and reference numerals as those of the first embodiment are the same as those of the first embodiment.

[0094] Figure 11 The flow of jam occurrence in the second embodiment is shown. Since steps S111 to 116 are the same as the processing in the first embodiment, description thereof will be omitted, and step S117 added in the jam information display section 32 will be described.

[0095] When the paper jam procedure occurs at step S114, the paper position calculation section 20 notifies the paper jam information display section 32 of the occurrence of the paper...

Embodiment 3

[0101] Next, a third embodiment will be described. In this embodiment, the conditions for occurrence of paper jams are set in advance, and paper jams occur when the set conditions are reached. However, the difference is that the paper feeding simulation is displayed on a touch-sensitive panel display 50 located in the operation section 17 of the image forming apparatus.

[0102] Also, in the present embodiment, since the conveyance state of paper and the occurrence state of jamming are displayed on touch-sensitive panel display 50 by actually conveying paper by rollers, the word "virtual" is not used.

[0103] Fig. 15 shows a design support device according to the present invention. The design support device of this embodiment can display the paper feeding status of the imaging device in the imaging device, and is used to support the control timing design of firmware software for controlling the imaging device.

[0104] The software part 1b is built-in software related to pa...

Abstract

A design support method which enables the verification of processing operation of software which controls a sheet conveying mechanism by displaying the process, in which a virtual sheet is conveyed, on a display portion, comprising a first procedure of setting failure occurrence conditions of a virtual device beforehand, a second procedure of judging whether the failure occurrence conditions set in the first procedure are satisfied, and a third procedure of generating a failure of a virtual device when it is judged in the second procedure that the failure occurrence conditions are satisfied.

Description

technical field [0001] The present invention relates to a design support method for supporting mechanism control design. More specifically, it relates to a design support method of software for controlling a conveying mechanism for conveying sheet-shaped conveyed objects. Background technique [0002] Hitherto, conveyance of a sheet-shaped conveyed object such as paper (hereinafter simply referred to as paper) has been carried out in all fields. For example, in image forming apparatuses such as copiers and printers, paper is conveyed by a conveyance mechanism such as rollers and guides. [0003] When conveying paper, in many cases, paper is rarely conveyed only in one direction, only at a constant speed. For example, a sensor is usually used to stop the paper at a predetermined position; and the paper is reversed by rotating the roller in reverse. Therefore, when conveying paper, software for controlling a mechanism for conveying paper is indispensable. [0004] In addit...
