Abstract

PURPOSE:To improve remarkably operating efficiency by providing a counter in which 1 is subtracted or added at every end of one copying and lighting up any of lamps contained in plural switch parts in accordance with the content of the counter. CONSTITUTION:All the lamps RL1-RL4 are set in a lighting up state when a ready state to permit a copying operation is attained. When any of push buttons 8-11 is pushed down in this stage, the pushed switch is detected and is stored into a RAM; at the same time, a CPU11 lights up only the lamp contained by the pushed down switch and sets the internal counter to the number printed on said switch. The copying cycle is thereafter started and when one copying ends, the pilot lamp is changed over to the built-in lamp of the switch on which the number smaller by one than the previously displayed lamp. All the lamps are again lighted up and the ready state to permit copying is set when the copying ends. The copying operation can be made simply by pushing the corresponding push button switches 8-11 and therefore the operating efficiency is remarkably improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a print switch device for a copying machine control panel that can simultaneously set the number of copies from the same original when the print switch is pressed.

<Prior art and its disadvantages> Figure 4 shows a case where a 10 key is provided as the number of copies setting key 2 on the control panel l of a copying machine. It is used in This lO key allows you to set the number of copies by pressing the required number one digit at a time. The set number of sheets can be confirmed on the display section 3. Also,
The clear key 4 is used to step or clear the operation when the set number of copies is changed or a mistake is made. Fig. 5 shows a control panel l of the copier with 2 keys provided as the copy number setting key 2. It shows the case,
Conventionally, it has been mainly used in copiers with slow copying speeds. By continuing to press or repeatedly pressing the number up key 5, these two keys can increase the number on the display section 3. By continuing this operation until the required number of copies is reached, the number of copies can be set. It is now possible to do so. If you accidentally increase the number of sheets too much, you can reduce the set number by operating the number down key 6.

The clear key 4 is used in the same way as the 10 key.

In this method, since the number of comparative keys is small in the case of 10 keys, there is a cost advantage.

However, in order to set the number of copies per copy, the control panel l of a conventional copying machine only has a copy number setting key 2, which is either the IO key or the 2 key. It is necessary to press the print switch 7 after operating the number-of-copies setting key 2, and when copying a large number of originals one by one, the operation is troublesome and the work is troublesome.

<Purpose of the invention> In a copying machine actually used for general office use, the number of copies made from the same document is not that large in most cases, and the most frequently set number of copies is two or three. It has become. For this reason, several printed switches are installed,
If you set the number of copies to be set for each print switch to correspond to one to several copies, and press one of the print switches, the corresponding number of copies will be automatically copied. This can now be done by simply pressing the print switch, and work efficiency can be greatly improved with only a small cost increase associated with the print switch.

Therefore, an object of the present invention is to enable a predetermined number of copies to be set at the same time as the start of the copying operation by operating the print switch, so that if the number of copies is between 1 and 2, the copying process can be completed by simply operating the print switch. The purpose is to provide a printed switch that can perform the following steps.

Another object of the present invention is to reduce the area of the control panel by displaying the number of remaining copies and the number of copies per copy using a lamp built into the print switch section each time copying is performed. An object of the present invention is to provide a print switch device with improved performance.

<Structure and effects of the invention> This invention is constructed as follows.

The print switch is composed of a plurality of switch parts each having a built-in lamp, and each switch part is configured to be operated independently. When one of the plurality of switch sections is turned on, a predetermined number of copies or zero is set corresponding to that switch section, and a counter that subtracts or adds one each time copying is completed; A lamp lighting means is provided for lighting any of the lamps built in the plurality of switch parts in accordance with the contents of the counter.

With this configuration, when one of the plurality of switch sections is turned on, the predetermined number of copies corresponding to that switch section is first displayed by the lamp that displays that number, or all the lamps are turned off. The light goes out, and then each time a copy is completed, the number of copies subtracted by 1 from the initial number of copies is displayed by the lamp that displays the number of copies, or the number of copies added by 1 is displayed by the lamp that displays the number of copies. attitude(.

With this structure, according to the present invention, once the original is finished, the copying operation can be performed simply by operating the switch section corresponding to the number of copies of the original. This has the advantage of saving time and effort in setting the copying machine, and significantly improving the operability of the copying machine. Furthermore, since the number of remaining copies and the number of copies are changed using a lamp built into the switch section, space on the control panel can be saved and there is no need to provide a separate number display. Furthermore, since the operator only needs to pay attention to one part of the print switch before copying, the operability is further improved.

<Embodiment> FIG. 1 is a partially enlarged plan view of a control panel of a copying machine which is an embodiment of the present invention.

The control panel 1 of the copying machine of this embodiment is constructed by providing a print switch 7 divided into four parts next to a clear key 4. The print switch 7 is made up of four independent push button switches (switch parts) 8-1)
It is a mosaic combination of push button switches, each with a built-in lamp. In addition, the letter "1" is printed on the rear push button switch 8, the letter "2" is printed on the front push button switch 9, and the letter "3" is printed on the left push button switch 10. The letter "4" is printed on each of the right push button switches 1).

FIG. 2 is a block diagram of the control section of the copying machine. The on/off signals of the push button switches 8 to 1) are input to the CPU II via the I10 device 10 along with various input signals. CPUI 1 has ROM1 that records the program program.
2. A RAM 13 is connected to which various data storage areas, counters, etc. are allocated. CPUI
Output data is sent from the I10 device 14 to a lamp driver 15 and an output load 16. The driver 15 supplies current for lighting up the lamps RL1 to RL4 contained in the push button switches 8 to 1), respectively. In this embodiment, all of the lamps RLI to RL4 are set to a lit state when the copying operation is possible. When the CPU t t is in the ready state and any of the push buttons 8 to 11 is pressed, the CPU t t detects the switch and stores it in the RAM. At the same time, the CPU II lights only the lamp built into the pressed switch.
Set the internal counter to the number printed on that switch. After that, the copy cycle starts and when the copy is completed, the display lamp is switched to the built-in lamp of the switch printed with a number one smaller than the number displayed last time. When all the copies are completed, all the lamps are turned on again to set the copy ready state.

FIG. 3 is a flowchart showing the operation of the control section.

After turning on the power, step nl (hereinafter step ni is simply n)
It's called i. ) to initialize the RAM 13, photosensitive tram, etc., and enter the n2 warm assembly cycle. When the temperature of the fixing section reaches a predetermined temperature, the process proceeds to n3, where all the lamps RLI to RL4 are turned on to notify the operator that it is in the ready state. Next n4. n6. n8. n
lO each snap step push button switch 8~1) (
Wait until one of SWI-3W4) is turned on. In this routine, for example, when the pushbutton switch 1) is pressed, that is, when the switch SW4 is pressed, ni
1, sets "4" to the counter C in the RAM, turns on only the lamp RL4, and turns off the other lamps. Through this operation, the state in which all the lamps were lit is changed to a state in which only the lamp built in the push button switch 1) is lit.The operator thereby knows that there are 4 copies remaining.Continued The process then proceeds to n12 and executes a copy cycle. Thereafter, the counter content is subtracted by l, and in n13 it is determined whether the content of the ζ counter is less than or equal to 1. If it is not smaller than l, proceed to n14,
Here, the lamp corresponding to the contents of the counter at that time is turned on, and the lamp that was turned on last time is turned off. In the above example, when one copy is performed, the lamp built in the push button switch 10 is turned on at n14, and the lamp built in the push button switch 1) is turned off. Thereafter, the process returns to n12 to execute the next copy cycle, and repeats until the content of the counter becomes less than 1 in n13. n1
If the contents of the counter become smaller than 1 in step 3, the scheduled number of copies has been completed, and the process returns to step n3 again. This lamp is turned on again to notify the operator that it is ready, and the push button switch is turned on. Accepts inputs from 8 to 1).

In this embodiment, a finite number from 1 to 4 can be set as the number of copies to be made. For example, in Fig. 1, the push button switch 1) is used as a continuous copy switch, and when this button is pressed, copies are made at n12. Continuous copying becomes possible by not subtracting 1 from the contents of the counter after the cycle is executed. During this continuous copying, the copying can be ended at any time by pressing the clear key 4.

In addition, in the above embodiment, the contents of the counter are decremented each time one copy is completed, and the number on the push button switch displayed by the print switch 7 decreases accordingly. When the push button switch is pressed, all lamps are turned off, and when one copy is completed, 1 is added to the counter, and the number on the push button switch displayed by the lamp is increased by 1. You can also do as you like. In this case, n5. n7. n9. At each nil, the counter is cleared and all lamps are set to off, and at the end of each copy cycle, 1 is added to the contents of the counter, and at n14, the lamp that was displayed last time is turned off, and then Turn on the lamp that displays the number that is one more. By performing such control, it becomes possible to display the number of copies each time a copy is completed.

With the above control, if you are making copies of 1 to 4 sheets, which are often used for general office purposes, you can perform the copying operation by simply pressing the corresponding pushbutton switch 8.~1). Since there is no need to set the number of sheets, work efficiency can be greatly improved. Furthermore, each time one copy is completed, the current number of remaining copies or the number of copies that have already been completed can be displayed at the position of the print switch 7, which has the advantage of further improving work efficiency.

In the above embodiment, a printed switch is shown in which four push button switches are combined, but a number of push button switches other than four may be combined as necessary. Furthermore, instead of using independent pushbutton switches, a pudding I switch, such as a multi-directional switch, that can selectively operate a plurality of switch sections depending on the direction of operation may be used.

It should be noted that the control panel of the copying machine of this invention does not have the conventional l
A copy number setting key such as the O primary key 2 key may also be provided. In this case, normal copying operations can be performed using only the print switch, and this copy number setting key can be used only when making a special number of copies. Just use the one sheet number setting key.
