Abstract

PURPOSE:To simplify a constitution of a titled device by detecting an operation time of a copying sheet number setting key corresponding to each display digit of an indicator, comparing it with a time prescribed in advance, and increasing or decreasing a numerical value of the display digit. CONSTITUTION:When a copying sheet number setting key 3b of the first place is operated by less than a time TA, a numerical value of a display digit 4b is brought to increment by ''1'' each, and when it is operated continuously exceeding the time TA, it is brought to decrement by ''1'' each after the time TA elapses, and thereafter, after a time TB elapses, said numerical value is further brought to decrement by ''1'' each, and after the numerical value of the diplay digit 4b of the first place has become ''0'', when its copying sheet number setting key 3b is further operated continuously, the numerical value ''0'' is brought to decrement in order of a numerical value ''9'' and ''8''. Such an operation is exexuted in the same way with regard to a copying sheet number setting key 3a corresponding to a display digit 4a of the ten place, as well. In this way, the copying sheet number setting key corresponding to each display digit is provided, and the numerical value of each display digit is changed, therefore, a small installation space is enough, and also the constitution is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for setting the number of copies of a copying machine.

In the typical prior art, a numeric keypad is provided to set the number of copies, and the entire number of copies is set in multiple digits by sequentially operating the numeric keypad. In such prior art, the number of keys is large, and therefore the installation space is large.

There are other prior art techniques that increment the set number of copies in stages by holding down the number of copies setting key for a predetermined period of time; There is nothing to do, and it takes a lot of effort to change the number of sheets.

An object of the present invention is to provide a copy number setting device for a copying machine that requires less installation space, has a simple configuration, and is capable of incrementing or decrementing a set number of copies by changing the operation time of a number setting key. The goal is to provide the following.

FIG. 1 is a perspective view of a transfer type electrostatic copying machine equipped with an embodiment of the present invention. The operation panel 2 of the machine body 1 is provided with a copy number setting key 3.

The copy number setting key 3 is the 10th copy number setting key 3a.
and a first copy number setting key 3b.

The number of copies set by the copy number setting key 3 is displayed on the display 4. The display 4 includes a 10th display digit 4a and a 1st display digit 4b. This operation panel 2 also includes a power switch 5, a print key 6 for starting the entire cover-up operation, a density setting switch 7 for fully adjusting the copy density, and close-up copy number setting keys 3a, 3b. There are provided an interrupt key 8 which is operated to perform so-called interrupt copying while the set number of copies is being copied, and a clear key 20 which is used as an initial constant when the number of copies is different. The original held by the original holding cover 9 is copied onto copy paper fed from a cassette 10 mounted on the side of the machine body 1.
The copied paper is discharged onto a tray 11 attached to the other side of the machine body 1.

FIG. 2 is a block diagram showing the electrical configuration of one embodiment of the present invention. Outputs from the copy number setting keys 3a, 3b are input manually to a processing circuit 12 realized by a microcomputer or the like. Through this operation of the processing circuit 12, the drive circuit 13 fully drives the display 4. The display digits 4a, 4b of the display 4 may be composed of segments of 7B font, for example.

FIG. 3 is a flowchart for explaining the operation of the embodiment shown in FIG. 2, and FIG. 4 is a diagram for explaining its display mode. When the copy number setting keys 3a and 3b are not operated, the 10th display digit 4 on the display 4
a is rOJ, the first display digit 4b is "1",
In this way, the set number of copies is "01". Therefore, a single copy can be made.

The entire operation for making multiple copies will be explained.

For example, a case will be described in which the copy number setting key 3b corresponding to the first display digit 4c is operated. Copy number setting key 3b
When i is operated, the operation of the copy number setting key 3b is detected in step n1, and the timer A provided in the processing circuit 12 starts clocking in step n2. In step n3, it is determined whether or not timer A has clocked for a predetermined time TA. In this way, the operation time of the number of copies setting key 3b is compared with the predetermined time jjJ T A, and when the operation time is the time TA Kimitsu, the process moves to step n8, and the operation of the number of copies setting key 3b is released. When it is determined that this is the case, the process moves to step n9, where the display digit 4b corresponding to the number of copies setting key 3b is incremented by 1 in total, and the number of copies heard for the first time is 12.
becomes. Similarly, press the copy number setting key 3b for a time T.
If less than A is operated, steps n1 to n2. n3.
The numerical value in the display digit 4b is further incremented by 1, and the set number of copies becomes "3".

Copy number setting key 3b-i When the operation is performed for more than the time TA in step n3, the process moves to step n4, where the numerical value in the display digit 4b corresponding to the copy number setting key 3b is decremented by 1, and the set number of copies becomes "2". . step n
At step 5, timer B included in the processing circuit 12 starts clocking. In step n6, it is determined whether or not the clocking time of timer B has passed a predetermined time TB;
If the elapsed time has elapsed, it is determined in step n7 whether the operation of the number of copies setting key 3b (p) has been released.If the operation of the number of copies setting key 3b has been released, the process proceeds to step n7.
1, and if the copy number setting key 3b continues to be operated, the process moves to step n4. Copy number setting key 3b
has been operated since time T'A as described above, and the display digit 4b
When is displaying the numerical value "2", if the operation is continued for more than time TB, the process moves from step n7 to step n4.
The value in the display digit 4b is decremented to 11''.0 After that, once the operation of the copy number setting key 3b is released,
If you operate the operation for more than time TA again, or if you keep pressing the button continuously, the number of copies will be "00" according to display digits 4a and 4b.
After that, by operating for more than time TB, the numerical value in the display digit 4b becomes "9", and by further operating for more than time TB, the numerical value becomes "8". In this way, when the first copy number setting key 3b is operated for less than the entire time TA, the numerical value in the display digit 4b is incremented by 1, and when it continues to be operated for more than the time TA, it is decremented by 1 after the time TA has elapsed, and then After the time TB elapses, it is further decremented by 1 and the first displayed digit is 4.
After the value of b reaches "0", press the copy setting key 3.
When b is further preserved and lost, several iMro
J is incremented in the order of number 41e, r 9 J +18. This operation is similar to the copy number d setting key 3a corresponding to the 101 display digits 4a.

For example, the time is 0.5 seconds, and the time TB is, for example, 0.3 seconds.

In this embodiment, after the numerical value of the display digit 4b becomes "0",
Furthermore, when the number of single shots setting key 3b is operated, it becomes "9".
Since the subtraction operation is subsequently performed, there is an advantage that the operation time is short when attempting to set the first numerical value to "9" or a value close to nine. Such an operation is also similar to 4> in relation to the copy number setting key 3a corresponding to the 10th display digit 4a.

As another embodiment of the present invention, three or more copy number setting keys may be provided, and according to the present invention, as shown in the table above, a corresponding copy number setting key is provided for each display digit. The numerical value of each display digit is incremented or decremented depending on the operation time of this copy number setting key, so the display digit is generally set to 2.
, up to three digits requires less installation space and has a simpler configuration than the numeric keypad described in connection with the light row technology.
