Abstract

PURPOSE:To eliminate easily the factor of a fault by adding a memory means to store an operating procedure. CONSTITUTION:An output signal 2 given from an operating input device 1 is sent to a CPU5 via an interface I3 and also to a RAM8 incorporating a timer in the form of an output signal 16. The RAM8 stores the pushing order (time) of keys of the device 1. When a fault occurs, a user connects an output reader S to an electronic device F and delivers an output instruction signal 14 through the deice 1 for operation of the output instruction. The interface I3 receives the signal 14 and sends an output signal 15 to the RAM8, reads out the stored operating procedure and prints out this procedure via an interface II 11. It is also effective to store the keys in the pushing order in place of the pushing order (time) in terms of the storage contents of the RAM8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an operating procedure memorization type electronic device having a debugging function.

[Prior art]

In recent years, typewriters, computers, and especially copying machines have tended to have multiple functions and specifications, and their operating specifications have also become more complex.

However, in conventional machines of this type, when investigating malfunctions or failures during manufacturing inspections or on the market, the operating status of the user is often unknown because there is no operation memory device, and the same phenomenon may be detected. Since it cannot be reproduced, the problem is that it is impossible to elucidate the phenomenon or improve the software.

〔the purpose〕

The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to facilitate elucidation of the causes of equipment abnormalities by providing a storage means for storing operating procedures in the operating system of the machine. That is.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, I will explain the configuration.

In the configuration diagram of the operation procedure memorization type copying machine F and the output reading device S shown in FIG. An interface I, 5a, performs processing such as encoding, and a CPU, 6, controls the machine and outputs the required output based on the output signal 4 from the interface 3.
RAM set and timer start signals sent from PU5 to RAM8 with a built-in timer, 7 is also the CP
RAM address signal from U5, 8 is RA with a built-in timer that stores the order (time) in which the keys of the operation input device are pressed.
An area for storing the order (time) in which certain keys are pressed in M is predetermined. Reference numeral 9 denotes a battery as a backup power source attached to the RAM 8 in consideration of the case where the power is turned off due to jam clearance, etc.; 10 denotes a RAM output signal for outputting the memorized operation procedure of the user to the interface I[11; 12; is an output signal from the interface I[11, and is output to the printer 13 or other output device. Note that the output reading device S has an interface 11.
11 and a printer 13.

Further, 14 is an output command signal from the operation input device 1 to output stored data from the RAM 8 in order to confirm the operation procedure when an abnormality such as a bug occurs, and is input to the RAM 8 as an output signal 15 processed by the interface 3. do. In addition,
The output signal 16 of the operation from the interface I3 is input to the RAM 8.

Next, the operation will be described based on the flowchart shown in FIG.

Generally, the operations of a copying machine include setting the number of copies, selecting the upper or lower paper cassette, and setting the magnification.

There are many settings such as copy density.

For example, suppose that the setting for the number of copies is first input by the user into the operation input device 1 of the copying machine F (ST
EP-1), the operation output signal 2 is multi-signal processed by the interface 3 and becomes the operation output signal 4
The signal is input to the PU 5 to control the operation of the machine, and outputs the signal 6 to reset the RAM 8 and start the timer. Further, a RAM address signal 7 is output from the CPU 5, an address corresponding to the RAM 80 input mode is specified, an operation output signal 16 is input as data to that address, and the operation for setting the number of copies is stored (S
TEP-2).

Next, when another operation, for example, selection of a paper feed cassette, is input into the input device 1 (STEP-4'), the cassette selection operation is stored at the corresponding address in the RAM 8 in the same manner as the address specification described above. (STEP-5). In this way, a series of operating procedures such as setting the magnification (STEP-7) and setting the copy density (STEP-1o) are performed one after another.
This memory is retained in AM8 until the copying machine F completely completes the copying operation and the next series of operating procedures are set (5TEP-8, 11). That is, when the setting is newly started, the RAM 8 is reset and stores the new operating procedure.

If an abnormality such as malfunction or runaway occurs during operation input, copying, or after copying (STEP-3, S”T
EP-6, 5TEP-9, 5TEP-12), the user cancels the next setting, so the memory of the operating procedure remains retained. Therefore, in order to investigate the cause of the abnormality, the output reading device S is electrically connected to the copying machine F, and the output command signal 14 is inputted to the operation input device 1.
The output signal 15 processed by the interface I3 is inputted to the RAM 8, and the stored operation procedure is inputted to the RAM output signal 10 as the output signal 12 processed by the interface π11, and then output to the printer 13 or other device. Output to an output device (not shown) (STEP-13). By analyzing this output, errors in the setting procedure can be easily discovered, and the errors can be immediately resolved and prevented from occurring again.

Furthermore, although the 'RAM 8 stores the order (time) in which the keys were pressed, it may also store which keys were pressed in the order in which they were pressed.

〔effect〕

As explained above, according to the present invention, by adding a storage means for storing operating procedures and combining a device for outputting and reading the stored data, bugs can be discovered and software can be corrected quickly. It has the effect of being able to be applied.

It is also possible to check whether the machine is correctly recognizing the operation input signal.
