Abstract

PURPOSE:To prevent a copying operation from being discontinued or suspended due to carelessness, by constituting the titled machine so that a key operating signal can be received by continuing a key operation for a comparatively long time in the course of performing copying operation. CONSTITUTION:When a key operation has been executed, whether a copying machine is performing a copying operation or not is identified by an identification means. When it has been identified that the copying operation is being performed, a key operating signal receiving time is set to a long time by controlling a time setting means by a time control means, therefore, in case of the key operation of a short time, a key operating signal is not received, and only when the key operation has been deliberately executed for a long time, the key operation is received. On the contrary, when it has been identified that the copying operation is stopped, the key operating signal receiving time is set to a short time by controlling the time setting means by the time control means, therefore, even in case of a key operation of a short time, the key operating signal is received. In this way, such inconvenience as the copying operation being discontinued or suspended due to carelessness can be surely prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a copying machine, and more specifically, to a copying machine that accepts at least IFJ type key operations during a copying operation.

<Prior Art> Conventionally, copying machines accept all key operations when a copying operation is not being performed, and clear key operations and interrupt key operations when a copying operation is being performed. , only limited types of key operations such as preheat key operations are accepted.

By adopting such a configuration, it is possible to obtain a copy as desired by the operator by accepting all key operations to set various conditions for performing a copying operation. Additionally, during the copying operation, in order to prevent the copying conditions from being changed, many types of key operations are not accepted, thereby ensuring that the desired copy can be obtained. In order to obtain an urgent copy or to stop the copying operation in an emergency, only interrupt key operations, clear key operations, all clear key operations, and preheat key operations are accepted. ing.

<Problems to be Solved by the Invention> In the copying machine having the above configuration, if the interrupt key, clear key, all clear key, or preheat key is operated by mistake during the copying operation, There is a problem in that the previous key operation is immediately accepted and the previous copying operation is interrupted or stopped.

To explain in more detail, in recent copying machines, the sensitivity of the various keys has become higher, and it has become possible to determine that a key has been pressed even if the key is accidentally touched lightly. Therefore, even if the operator has no intention of operating a key at all and even touches the key lightly, for the limited types of keys listed above, the system immediately accepts the key operation and interrupts the previous copying operation, or It would have to be cancelled. In such a case, the operator is completely unaware that he or she has pressed any keys, so the copying operation may be interrupted or canceled by mistake, and the settings may be changed, resulting in the initial settings being changed. This means that you will not be able to obtain the same number of copies. Furthermore, it is only when it becomes clear that the initially set number of copies have not been obtained that the above-mentioned copying operation has been interrupted or stopped, and it is necessary to repeat the copying operation for the remaining number of copies. Because it will no longer be
This causes an inconvenience in that the overall efficiency of office processing is reduced. In addition, when copying the remaining number of sheets, it may be necessary to set various copying conditions again, and in such a case, the efficiency of administrative processing will be reduced. It ends up.

<Object of the invention> This invention was made in view of the above problems,
To provide a copying machine that can surely prevent the inconvenience of interrupting or stopping a copying operation due to carelessness, and can also interrupt or stop the copying operation when necessary. It is an object.

<Means for Solving the Problems> In order to achieve the above object, the copying machine of the present invention has an identification means for identifying that a copying operation is being performed, and two types of time periods, long and short, for accepting key operation signals. a time setting means for setting the above-mentioned time to one of the two; and a time setting means for controlling the time setting means to set the above-mentioned time to the longer time by inputting an identification signal from the identification means indicating that a copying operation is being performed; and time control means for controlling the time setting means to set the above-mentioned time to the shorter time by inputting an identification signal indicating that the copying operation is being stopped.

<Operation> In the copying machine configured as described above, when a key operation is performed, the identification means identifies whether or not the copying machine is performing a copying operation.

If it is determined that the copying operation is in progress,
By controlling the time setting means with the time control means, the key operation signal reception time is set to the longer time, so if the key operation is for a short time, the key operation signal will not be accepted, and the key operation signal will not be accepted, and the key operation signal will be intentionally pressed for a long time. A key operation signal is accepted only when an operation is performed.

Conversely, when it is determined that the copying operation is stopped, the time control means controls the time setting means to set the key operation signal reception time to the shorter time.
To accept a key operation signal even if the key operation is for a short time.

In other words, if the copying operation is stopped, a key operation signal can be reliably input even if the key is operated for a short time, whereas if the copying operation is in progress, the key operation is consciously performed. A key operation signal can be input only if the key operation is continued for a sufficient period of time to determine that

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 2 is a diagram showing the electrical configuration of an embodiment of the copying machine of the present invention, in which key switches (1) connected in a matrix are shown.
, and a CPU (2) which outputs a necessary copying operation execution signal in response to input of a key switch signal. In addition, the above key switch (1) is a numeric keypad (
11), print key (12), zoom key (13),
An interrupt key (14), clear key (15), all clear key (1B), and preheat key (17) are shown. The numeric keypad (11) is used for setting the number of sheets, etc., and the print key (11) is used for setting the number of sheets.
2) is used to start a copying operation, the zoom key (13) is used to select a variable size copying state, and the interrupt key (14) is used to start a series of copying operations. It is used to perform a series of other copying operations during the process, and the clear key (1)
5) is used to clear the set number of copies and to stop the copying operation, and the above all clear key (11m) is used to return to the initial state. The preheat key (17) is used to forcibly shift to the preheat state.

As is clear from the above description, the only keys that can be accepted during the copying operation are the interrupt key (14), clear key (15), all clear key (1B), and preheat key (17).

FIG. 1 is a flowchart for explaining the operation of key operation signal reception. In step ■, the clear key (
15) is operated, and clear key (15) is operated.
) has been operated, it is determined in step (2) whether or not a copying operation is being performed.

If it is determined that the copying operation is in progress in the above step (■), a timer (not shown) (
For example, a timer included in the CPU (2) is used)
A timing operation is started, and it is determined in step (2) whether or not the timer has expired.

If it is determined in the above step ■ that the timer is not up, proceed to step ■ with the clear key (15
) is continued, and if so, the determination in step (2) is repeated. Conversely, if it is determined that the operation of the clear key (15) is not continued, the operation signal of the clear key (15) is not accepted and normal control is performed as it is.

Further, if it is determined in step (2) that the copying operation is stopped, in step (2), the process corresponding to the clear key operation, that is, the clearing operation of the set number of sheets, is performed, and then normal control is performed.

If it is determined in step (2) that the time has expired, in step (2), the process corresponding to the clear key operation, that is, the copying operation is interrupted or canceled, and after clearing the set number of copies, normal control is resumed. Do this.

Further, if it is determined in step (2) that the clear key (15) is not operated, normal control is performed as is.

In summary, if the copying operation is stopped, if the clear key (15) is operated for only a short time, the clear key operation signal will be immediately accepted and the set number of sheets will be cleared, but while the copying operation is being performed, If there is, a clear key operation signal can be accepted only when the clear key (15) has been operated for a predetermined period of time or more, and the copying operation can be interrupted or stopped and the set number of copies can be cleared.

It should be noted that the present invention is not limited to the above-described embodiment; for example, in the flowchart of FIG. 1, the clear key (
Instead of determining whether or not 15) has been operated, it is possible to determine whether or not the interrupt key (14), all clear key (1B), or preheat key (17) has been operated. (14), clear key (15)
), all clear key (1B), and preheat key (17), it is possible to determine whether or not all of them have been operated, and furthermore, even when the copying operation is stopped, the key operation continues for a relatively short predetermined period of time. It is possible to accept key operation signals on the condition that the key operation signal is set, and various other design changes can be made without changing the gist of the present invention.

<Effects of the Invention> As described above, the present invention is capable of receiving a key operation signal by continuing key operation for a relatively short period of time while the copying operation is stopped; Since the key operation signal can be accepted by continuing the key operation for a long time,
This has the unique effect of reliably preventing the inconvenience of the copying operation being interrupted or stopped due to an inadvertent input of a key operation signal during the execution of the copying operation.
