Abstract

PURPOSE:To set automatically an operating mode by sensing the propriety of setting the mode based on the data stored at a mode information setting/ storing part, giving an access to said storing part according to a sensed contents for setting a mode and then replacing an area contents of the storing part holding the information which is under use. CONSTITUTION:A phenomenon detecting circuit 1 detects the generation of a phenomenon with which an operating mode should be set and informs it to other parts. Then the operating mode to be set is stored to a mode information setting/storing part 2 and then held by a data holding circuit 3. The propriety of setting the mode is displayed by a flag circuit 5 based on the information on the part 2. Then circuits 1, 3 and 5 and the part 2 are connected to a bus line 6. A control part 4 senses the state of the circuit 5 and an access is given to the part 2 as long as the circuit is set under an enable state. Furthermore a mode corresponding to the state of the circuit 5 is set at the circuit 3, and an area where the information used by the part 2 is turned into a used state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an operation mode setting method suitable for use in an information processing apparatus that operates in a plurality of modes.

[Technical background of the invention and its problems]

In recent years, among office automation devices, devices that perform multiple roles in one device have become widely popular, with catchphrases such as ``5 steps in 1''. An example of multiple roles is office computer functions and...
There is a motherboard computer function.

When designing the above-mentioned equipment, it may be created with completely new specifications, but there are also cases where the specifications of multiple independently existing equipment are immediately integrated into one unit. Immediately, the heritage of each device as an independent device (especially software and machine man interface) is enormous, and it is important to make the most of it. At this time, each of the existing devices has developed completely independently, so in order to integrate them into a single device while making use of that heritage, it becomes necessary to have completely different operating modes. - CRs that look identical to each other
The specifications of input/output devices such as T-Disgray and keyboard devices vary depending on the device, and the condition was set to be completely compatible with the software, which is the greatest legacy, to be able to do it with a single device. The necessity of this can be understood by considering the cases in which it will be realized.

There are various methods of setting the operation mode for the above-mentioned device having multiple operation modes.

For example, there is a method of checking how the mode setting switch is specified when the power is turned on, or a method of setting the mode from a keyboard or the like after the system starts up.

In any case, in many cases human intervention is required to set the operating mode.

On the other hand, as the production volume of office automation equipment has increased dramatically, automation has become an extremely important theme at production sites.

It is important to test equipment in a way that saves as much labor as possible. However, since the above-mentioned devices require human operation to set the operating mode,
In cases where the operation mode is changed several times in the entire process, this is not preferable in terms of labor saving.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide an operation mode setting method that makes it possible to automatically and flexibly set a mode when an event that determines an operation mode occurs. purpose.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention has added a function that allows the user to freely specify in advance a new operation mode to be set an arbitrary number of times when an event for specifying or changing an operation mode occurs. For this reason, in addition to the four components that this type of equipment configuration has as standard, there is also a mode setting event detection section, a data holding circuit that holds the operating mode, and a road/controller that stores the operating mode to be set. Wr i te
A possible operation mode information setting storage section, a flag circuit for determining whether the operation mode can be set for this storage section, and a control circuit are added, and the control circuit senses the state of the flag circuit and records its contents. Access the follow mode information setting storage section and set the mode according to the contents in the data holding circuit, and also check the contents of the corresponding area of the mode information setting storage section where the information currently being used is held. Update.

This makes it possible to save labor in setting the operation mode.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail using the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is an event detection circuit. The event detection circuit 1 detects the occurrence of an event that should newly set an operation mode, and notifies others. The other is a mode information setting storage section that stores an operation mode to be set when a mode setting trigger is applied by the event detection circuit. The mode information setting storage section can store information for each trigger multiple times,
Can be read and written. 2 is a data holding circuit that holds the set operation mode. A microprocessor 4 serves as the control center, and is responsible not only for controlling the entire device, but also for controlling operation mode settings. Hereinafter, it will be referred to as the control section 4 and will be described. 5
is a flag circuit. The flag circuit 5 indicates whether to enable or disable the setting of the operation mode based on the information stored in the mode information setting storage section Z. Each of the circuit blocks 1, 2, 3.5 is connected to a path line 6 of the control section 4.

FIG. 2 shows an example of the information stored in each mode information setting storage unit, and shows how the information changes each time the mode is set. In the embodiment of the present invention, for simplicity, two modes are set, A and B are operation modes, and N is an operation mode.
indicates used (already used for mode setting).

Hereinafter, the operation of the embodiment of the present invention will be explained in detail. The control unit 4 senses the state of the flag circuit 5, and if it is in the enabled state, accesses the mode information setting storage unit, reads out the corresponding mode setting information, sets the corresponding mode in the data holding circuit 3, and sets the mode. The area in the information setting storage section l where the currently used information was held is changed to a used state.

FIG. 2 shows in chronological order how the stored information changes each time the mode information setting storage unit is used to set the operation mode. From this figure, it can be seen that the operation modes are set to A, B, and A, and information that has been used once is rewritten to N (before use).

Incidentally, if the operating mode is determined when the power is turned on, the mode information setting storage section may be realized by a nonvolatile memory or an external storage device such as a floppy disk.

〔Effect of the invention〕

As explained above, according to the present invention, when an event to specify or change the operation mode occurs, the newly set operation mode can be specified freely and any number of times in advance, which saves the labor of setting the operation mode. can.
