Abstract

PURPOSE:To attain copying in a desired range only by inputting a range to be copied and comparing the range with a moving distance of the device. CONSTITUTION:When a part is desired to be copied for a prescribed interval only, the prescribed interval is inputted from a key group 52. A CPU30 subtracts the movement of the device from a setting value based on the setting of the movement and displays the result on a numeric display device 53. Then the moving setting value and the movement are compared in this case and when the movement is equal to the setting value or over, the copy is stopped. Since the range desired to be copied is inputted to the device in advance, the region desired to be copied is copied easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a control method for a so-called manual copying machine in which a document is manually scanned and an image is reproduced by a recording element onto a recording member that is conveyed in a complementary manner.

[Prior art]

N of traditional desktop or console copiers
Scanning during manuscript reading was precisely controlled using motors, microcomputers, etc.

However, in a small and portable recording device, copying is performed by manually moving the document from an arbitrary position to an arbitrary position t on the document, so it is very difficult to control the timing of the load. Furthermore, in order to obtain the desired copy area, K has to constantly check the position of the document, which is a hassle.

〔the purpose〕

The present invention has been developed in view of the above-mentioned points, and involves inputting the range (distance -) to be copied, comparing it with the moving distance of the device, and copying only the desired range.

Next, the operation and operation will be explained with reference to FIGS. 1 to 7. First, apply pressure to the solenoid 5oL-1a, day 0L
1b (FIG. 6) is OFF, the pressure between the transfer paper feed row 24-2 and the pressure plate spring 14 is released, resulting in a free state. Next, bring the roll paper 9 or the cut paper between the row 74-4 (Fig. 1) and the row 24-6 and rotate the dial D-i. The transfer paper feed rollers 4-2 and 4-24, which also have 7 lees, pass through between the Matsusha paper ejecting section 11).
7, the leading edge of the transfer paper is exposed outside the device when it is reversed. Stop the Dynor D-1 at this point, and then raise the paper discharge tray 12. The transfer paper is set by the above operation, and the leading edge of the transfer paper can be adjusted to the desired position using the dial b-1. The CPU lights up the light source 5 during these series of operations. Next, move the device 2 and align it to the leading edge of the document part you want to copy while looking at the position confirmation cell 7 and screen 8, which is imaged on the position confirmation cell 7 and screen 6-1. I do.

Thereafter, by pressing a pressure release switch (not shown), the copy permission indicator WD1 (Fig. 5) and the paper present indicator LED 2 are lit, and the solenoid oL that applies pressure between the pressure plate spring 14 and the roller 4-2 is turned on. Turn on -1a and 8oL-1b. At this time, for example, when the paper output tray 12 is tilted down, each display and light source 5 are turned off, making it impossible to copy, and when the paper runs out of paper, the paper presence indicator LED 2 is turned off.
, the copy permission display and LED 1 turn off, making copying impossible.

In addition, the CPU 50 has always been in a state where it can accept input from the key group 52.
The input distance data is displayed on the numerical display 53 at the same time.

Therefore, it is easy to attach a scale to the outer periphery of the device and use it as a scale, or to let the device run idly in advance, and then substitute that distance as a predetermined distance and display it on the numerical display 53. For example, as a condition for free running, press contact leaf spring 1
4 and roller 4-2, a distance measurement switch (not shown) is added (and an indicator indicating that the distance is being measured if necessary), and the distance measurement switch is pressed. In this case, the CPU enters the free running distance measurement mode, counts the amount of movement of the encoder m-1, and sequentially adds the moving scenery.
゛By displaying the display on the numerical display 53 and turning off the distance measurement switch, a series of operations such as storing the accumulated distance data in the memory are executed by CPUOR0 (not shown).
This is possible by adding it to the M section. In addition, even in the above-mentioned state where the copy operation is not performed, an auto shut-off timer (A, S, O) (not shown) measures the time, and after a predetermined period of time, the output of each display and light source etc. is turned off. and becomes unable to be copied. This mode is
If the paper discharge tray 12 is in a raised state, it can be released by folding it down once and then raising it again, or if the paper discharge tray 12 has fallen down, it can be lifted.

Next, the operation and operation of copying will be explained. First, the solenoid 5oL- which applies pressure between the pressure contact plate spring 14 and the roller 4-2
1a, 8oL-1b and copyable display LID 10 after sealing C
The PU 50 waits for a signal from the encoder E-1 that is linked to the roller 4-1 (Fig. 2), and when the device 2 is moved in the direction of arrow A (Fig. 1) with this ζ, the roller 4-1 rotates. However, multiple signals are obtained from the encoder E-1. As a result, the CPU outputs an output for moving a matrix (Fig. 6) of recording element groups divided into 16 in a predetermined arrangement within the pulse width of the signal from recording element group 1 to recording element group 16 OUT.
Control is performed at the timing shown in FIG. 7 as an output signal of 1 to 0UTt6. Encoder F again! If the pulse width from −1 is longer than the time required to drive the recording element group into 16 divisions (when the feeding speed of device 2 is slow), 1 of 16 divisions
It outputs only one line and waits for the next pulse. Also, encoder 1i! The pulse width from -1 to 1 of the recording element group
If the time is shorter than the time required to perform 6-division driving (when the feeding speed of the device 2 is fast), any of the recording element groups 1 to 16 recording element groups currently outputting at the end of the relevant pulse QUT
1 to 0 UT1 (after turning OFF S, stop the output and wait for the next pulse from encoder E-1. When this pulse is detected, the recording element group immediately after the stop is outputted multiple times, and the final output is After a certain recording element 16 group 01lT outputs 16, it waits for a pulse from the next encoder m-1.

Therefore, even if it is not possible to record the entire line while pulses are being output from encoder E-1, it will be recorded uniformly by the predetermined arrangement of the recording element group, and for the next line, the next line will be the next one after the recording element group that stopped at the previous line. Since the recording element is driven by a group of recording elements, there is no possibility that the same part is always left out of recording, resulting in an unsightly image. .

After these processes, the CPU measures the pulse width from -1 on the encoder, converts it into speed data for display, and displays the speed as a bar display (in this example, a bar display) (IJD 3 to LED) 9. At this time, if the above-mentioned predetermined movement amount has been set, the number of pulses from encoder m-1 is converted to the movement amount of the device 2, and subtracted from the set predetermined movement amount.

At this time, if the amount of movement of the device f2 is equal to or greater than the predetermined amount of movement, the pressure contact plate spring 14
and solenoid 8oL to release the pressure on roller 4-2.
-1a, 5oL-1b are OF'F', l.As a result, the conveyance of the recording paper is stopped by releasing the pressure, and the CPU processing returns to the standby state, otherwise proceeding to the next processing. At this time, writing on the recording paper is also stopped. Also, if the predetermined movement amount has not been set, encoder E-1
The number of pulses from is converted into the amount of movement of the device 2, and this value is sequentially added and stored in the memory, and the amount of movement is displayed on the numerical display 55. Further, the stored movement amount of the device is erased only in a clearing process during a standby state or in an all-clear after a predetermined period of time has elapsed (auto shutoff), and the display is also turned off at that time.

With these, the υ writing part is the SELFOC 6-2 for sensor reading.
The reflected light from the original is imaged on the sensor section of the reading/writing section 7, compared with the immediately previous pixel data, and the binarized pixel information is transferred onto the transfer paper 9 at a ratio of 1:1. Also, this device 2 is moved and rollers 4-1. Transfer paper feed roller 4 is rotated by
-2, the driving force (document movement amount) is transmitted to feed the transferred transfer paper in the direction of arrow B (FIG. 1).

At the same time, the rotation speed of roller 4-1 is increased to eliminate deflection, wrinkles, etc. in the reading section of the document, and a sponge roller 4 (other materials may be used as long as the frictional resistance is low) is positioned in the direction of extending the document to both ends of the device 2. -5a, 4-3b (Figure 2)
Rotate. Copying is completed when the amount of movement of the device equals or exceeds the set value of the predetermined amount described above, by removing the transfer paper from the transfer section, or by tilting the paper output tray 12. That's fine. Also, in the processing during copying, if the CPU does not receive a predetermined input even after a predetermined period of time has elapsed, the CPU 2 stops and the encoder E-j linked to the roller 4-1 cannot receive a signal. In this case, all outputs are set to 0FIT' as in the case of standby, and the copy state changes to the standby state. In addition, this state can be canceled by performing the operation of raising the paper ejection tray 12 again by lowering it if it is up, or raising it again if the paper ejection tray 12 is down, as described in the explanation during standby above. It is something that will be done.

Although the explanation has been made above, there are no particular limitations on the operating procedure, operating conditions, etc.

Next, the sequence flowchart in Figure 8 is shown in Figures 1 to 7.
This will be explained with reference to the figures.

When the device is in standby state, all outputs and memory (RAM) are initialized (STEP 1).
), the light source 5 and each display are OFF' (5TIIUP 2 ). Also, at this time, the auto-shutoff timer (A, s, o) has started (S

Also, if there is an input to clear the set value, the numerical display will be blanked (turned off) and the set value stored in the RAM will be cleared (

Start the 0 timer (8TWP 25) and set n to 1.
The output signal is incremented by 1 (STEP 26), and a signal is output from the n-th output terminal OUT n to drive the n group of recording elements (5TEP 27). After outputting a pulse of a predetermined width, turn off the signal from terminal OUT n.
Stop driving the n group of recording elements (87BP 2B)
. ξ is repeated until n=16t, that is, until all the recording element groups have been driven, but if driving up to 16 recording element groups has not been completed, check whether the A, S, and O timers have timed up. Please judge 5TrtiP 29, 31),
If the time is up, A1 day, 0. Set F and return to standby state. If no time-up has occurred and there is a signal from encoder B-1, the process is repeated until n=16 (sTgpg2). When the signal from encoder E-1 disappears, check whether or not A, S, and O have timed up. If they have timed up, set A, S, O, and F and repeat the flow from 5TEP 2. (EITEP

Sensors BF-4 and BK-2 are ON (when the paper output tray 12 is raised and there is paper, if there is a signal from the encoder 1, the flow from step 35 is a,!7). Return 6TBP 38), if there is no signal, convert the immediately preceding pulse width to speed display data and display it on speed display LEDs 5 to 9 (STEP 3B, ?+

5Txp 40), and determines whether there is a movement amount setting (5TEP 41). If the amount of movement is set, the amount of movement of the device is subtracted from the set value and displayed on the numerical display 55 (5TBP 42). At this time, the movement fine setting value and the movement amount are compared (5TKP 41), and if the movement amount is equal to or greater than the setting value, pressure release solenoids 5oL-1a and 5oL-1b are turned on to stop copying.
FF (5TEP 4/l) and repeat the flow from 5TEP 3. Also, if the set value is smaller than the movement amount, the A, S, and O timers are started in order to continue copying (5TEP 45), and 7 from 8TEP 25 is started.
Repeat 0-. 5TEP If the amount of movement is not set in 1, the amount of movement of the device is added and displayed on the numerical display 53.
The amount of movement is displayed (STKP44).

〔effect〕

As described above, according to the present invention, since the range to be copied is inputted into the apparatus in advance, the area to be copied can be easily copied.

Furthermore, since copying is stopped when the input setting value is reached, there is no waste of recording paper.
