Abstract

PURPOSE:To prevent the discontinuity of input or output of a picture by providing a marker which marks a recording medium and an original and an aligning member which aligns a device to marks. CONSTITUTION:At the recording time, a recording device A is placed on the prescribed position of a recording medium B and a switch 14 is turned on to mark the recording medium B by plotters 11 and 13. The device A is moved in the direction of an arrow Y to record a pattern or the like. After the recording operation of the first line, the switch 14 is turned on again to mark the recording mark B. The device A is so positioned that cursors 10 and 12 coincide with plotted marks, thereby feeding a line. In this position, the medium B is marked again to record the second line. As the result, interline spaces are uniform and end parts are made coincident between recorded preceding and current lines.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile recording and/or reading device, and particularly to a device that can easily and reliably realize line alignment and edge alignment at the time of line feed. .

[Prior art]

In a mobile image reading device or recording device that moves over a document to read an image or moves over a recording medium to record an image, it is necessary to perform a line feed operation on the document or recording medium. If the bottom end of the previous line (line) and the top end of the new line (line), the left end of the previous line and the left end of the new line, etc., do not fail, the continuity of the input or output image will be broken. spoiled in time.

That is, between rows, the state shown in FIG. 8(a) is normal, but the state shown in FIG. 8(b) tends to occur, and at the end, the state shown in FIG. However, it tends to become as shown in (b).

In order to solve such problems, for example, the following proposals have been made. That is, the sub-scanning direction of the device (
A direction regulating member is provided separately from the device so that the direction of movement (movement direction) is linear, and the direction regulating member is structured so that it can move a predetermined distance in the line feed direction and be held there at the time of line feed. There is a direction regulating device that prevents discontinuity of input or output in the line feed direction at the time of line feed (Japanese Patent Application Laid-Open No. 59-114078, Japanese Patent Laid-open No. 59-173).
879, 1987-10153, 1987-15
254).

In some of these, the print start position and end position in the sub-scanning direction are set so that the print start position and end position do not differ between lines.

However, all of these require the use of a direction regulating device in addition to the image reading device and recording device. Therefore,
It is inconvenient to carry, and the objects that can be read and recorded are limited to manuscripts and recording bodies that can be used with direction regulating devices, and are limited by their size.

For example, in order to use a direction regulating device, the input/output range of a document or recording medium must be within a range that can be regulated by the direction regulating device. That is, for example, if the document or recording medium is significantly larger than the direction regulating device and thicker like a book or notebook, the setting of the direction regulating device becomes unstable and difficult to use.

[Purpose of the invention]

An object of the present invention is to easily match the lower end of the previous row and the upper end of the new row with a simple configuration, and also to easily match the scanning start and end positions between the previous row and the new row. The purpose is to prevent discontinuity of image input and output by making it possible to do so.

[Structure of the invention]

To this end, the present invention is configured to include a marker for marking a recording medium or a document, and a positioning member for aligning the mark made by the marker.

〔Example〕

Examples of the present invention will be described below. Figure 1(a)
, (b) show an example thereof, and show an example applied to an image recording device.

This image recording device A has two running rollers 2.3 arranged in parallel on the lower surface of an outer box l of the device.
．． A recording window 4 is provided in the middle part of 3;
A recording head (thermal head) 6 protrudes from the recording head whose back surface is pressed by a compression spring 5 and whose vertical movement is guided by a guide mechanism (not shown). This recording head 6 has an element portion 6 at its tip which is a heating element having a length β.
A is provided. Reference numeral 7 denotes an ink ribbon suspended from the tip of the recording head 6, and heat is generated from the element section 6a of the recording head 6 to thermally transfer the ink ribbon to the lower recording medium B. A timing belt 8 transmits the rotation of one roller 2 to an encoder 9 that generates a recording timing signal. Note that the ink ribbon 7 is wound using the rotational force of a motor, but this is not shown.

In this embodiment, in such an image recording apparatus A, a cursor 10 and a solenoid-driven marker as a marker are placed on one side surface 1a of the outer case 1 corresponding to the front and back of the moving direction Y, which is the sub-scanning direction of the apparatus A. A plotter 11 is provided, and a cursor 12 and a plotter 13 are also provided on the other side 1b.
has been established.

14 is a block drive switch.

Cursors 10 and 12 are the element section 6 of the recording head 6.
The plotter 11.13 is installed at a level position corresponding to the level of one end in the longitudinal direction of length l, and the plotter 11.13 is installed at a level position corresponding to the level of the other end. Therefore, the distance between the cursor 10 and the plotter 11 and the distance between the cursor 12 and the plotter 13 are the same as the length l of the element section 6a.

FIG. 2 is a diagram showing a plotter driving circuit. Solenoids lla and 13a of blocks 11 and 13 are commonly connected to the output side of a switching transistor 15, and the transistor 15 is connected to the differential circuit only when the switch 14 is turned on. It is turned on momentarily by the differential pulse from 16, and the solenoid 11a513a is momentarily operated. 17 is a bias resistor, and 18 is a discharge resistor.

When recording, the recording operation is performed according to the following procedure (see FIG. 3).

(2) When starting recording, place the recording device A at a predetermined position on the recording medium B, such as the upper left, turn on the switch 14, and mark the recording medium B with the plotter 11.13. The position of device A at this time is the position A in FIG.

■ When device A is moved in the direction of arrow Y, encoder 9
Data stored in a memory (not shown) is sequentially sent to the element 6a of the recording head 6 by timing pulses from the recording head 6, thereby recording figures and the like.

(2) When the recording operation for the first line is completed, the switch 14 is turned on again and a mark is placed on the recording medium B by the plotter 11.13.

The position of device A at this time is position A2 in FIG.

■、Move the cursor 1 to the mark plotted with ■ for device A.
By aligning so that 0.12 matches,
Begin on a new line. The position of device A at this time is the position A3 in FIG.

(2) At this position, a mark is again placed on the recording medium B using the plotter 11.13.

The second line is recorded by the same operations as ① and ②.

■, Near the end of the recording on the second line, move the cursor 10.
When the mark 12 matches the mark plotted in ■, a mark is placed on the recording medium B again using plotter E 1.13. The position of device A at this time is the position indicated by A4 in FIG.

(2) Hereafter, return to (2) and record the third and subsequent lines in order.

As a result, the recorded previous line and new line are completely aligned at the line spacing and end portions, as explained in FIG. 8 (al) and FIG. 9 (a).

Note that the recording device A needs to move straight without meandering, but the roller 2.3 is made of ethylene propylene rubber, for example, with a width of 80% of the width of the outer case 1 (width in the direction perpendicular to the arrow Y direction). , with rubber such as rubber with a hardness of 60 degrees.
If a device with a friction coefficient of about 0.8 is used, the straightness can be made sufficiently high, and unless the user intentionally applies force to the device A in the direction of travel, the device A will not move easily due to the curves during travel. It has been confirmed that overlapping lines and gaps in lines are almost negligible. Or move the roller 2
Alternatively, even if only one of the three is used and its surface material is the one mentioned above, the straightness is high. However, in this case, roller 2
It is better to provide a height reference protrusion on the side of rollers 3 and 3 that is not used as a roller in order to fix the inclination of the device A with respect to the paper surface.

Note that the blocks 11 and 13 may use a mechanism as shown in FIG. This mechanism connects the plotter 11 to an arm 19, and connects the arm 19 to a tension spring 2.
Plotter 1 can be pulled upward by 0 and pressed downward only when plotting.
1 comes into contact with recording medium B and makes a mark.

A plotter 13 is also attached to the other end of the arm 19, so that when the button 21 is pressed, a mark is made by the plotter 11, 13 at the same time.

As the pen used as the plotter 11.13, in addition to a general ballpoint pen or a felt-tip pen, a pen recorder type pen or an pencil can be used. It is also possible to use ink that automatically disappears after a predetermined period of time when plotted on paper.

Further, the plotter 11, 13 may be replaced with a needle-like object with a sharp or blunt tip, and a hole or a depression may be formed in the recording medium. Furthermore, the plotter 11, 13 may be used as a sticker dispenser to affix a sticker to the recording paper, or simply to place the sticker on the recording paper.

Furthermore, instead of a sticker, a tablet made of metal, plastic, or the like may be placed. In these cases, if you put a cross mark on the sticker or tablet, it will be easier to align the lines next time.

In addition, the cursor 10.12 and the plotter 11.13 have shapes that make their indicated positions clear in FIGS. 5(a) and f.
It may also be formed like the sharp points 22 and 23 in b).

Furthermore, if that part of the cursor 10.12 is made into a lens, it will be easier to align the cursor 10.12.

Furthermore, although the cursor and plotter were installed outside the outer box 1,
Of course, it can also be provided inside.

Furthermore, the alignment of the cursor 10.12 with the plotted mark does not have to be done visually, but it may be possible to automatically display whether or not the cursor has matched with the mark.

FIG. 6 is a circuit showing an embodiment of the present invention, in which the above-mentioned tablet is used instead of the block.

24 is the mark of the tablet, and if you turn on the switch 25, the light emitting diode 2 which is always on will light up.
At the time when the light 6 illuminates the mark 24, that is, when the alignment is performed, the reflected light from the mark 24 passes through the filter 27 and connects to the light emitting diode 26, forming a photocoupler. The output current of the phototransistor 28 is amplified by the transistor 29 in the next stage, and then the output current of the phototransistor 28 is amplified by the transistor 29 at the next stage, and the output current is outputted to the light emitting diode 30 for display.
lights up to indicate that alignment is complete. This display light emitting diode 30 may be a buzzer or the like.

Note that the element 6a of the recording head 6 does not necessarily use its length of 2 minutes all the time. That is, in some cases, recording may be performed in a portion shorter than the length l.

In such a case, the cursor should be adjusted so that the distance between the cursor 10 and the plotter 11 and between the cursor 12 and the plotter 13 can be adjusted to the distance corresponding to the length of the element 6a actually used. The position of the plotter 10.12 or the plotter 11.13 may be made movable along the length direction of the elm plate 6a.

Although the embodiment described above is applied to a recording device, it can be similarly applied to a reading device. FIG. 7 is a diagram showing one embodiment thereof. In this reading device C, components such as a running roller and an encoder can be the same as those of the above-mentioned recording device, so those portions are omitted.

In this embodiment, a movable plate (
The shutter plate 32 is movably guided in a direction perpendicular to the longitudinal force of the reading window 31 (direction perpendicular to the moving direction Y of the device) (the guide mechanism is omitted), and by the movement of the movable plate 32, the scale is Corresponding indicators 33.34
can be moved. The interlocking mechanism for this movement is
It was composed of pulleys 35-40 and wires 41-43.

In this embodiment, when the length l of the reading window 31 is changed to β' by moving the movable plate 32, the indicators 33.34 are moved by an interlocking mechanism using pulleys and wires, and the plotter 11.13 and its indicator 33. .34 is β'.

In this embodiment, a transparent cursor section 44.45 having thin lines 44a, 45a is further provided as shown in the figure for protecting the indicator, and the indicator 33.34 can be moved along the thin lines 44a, 45a. good.

Furthermore, it goes without saying that this embodiment may also be applied to a simple copying apparatus in which a recording device and a reading device are integrated.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to easily match adjacent parts and edges of a previous line and a new line during recording or reading, prevent overlapping of lines and occurrence of gaps, and make images continuous. It can be recorded and read without damaging it.
