The operation of the copying apparatus 10 configured as above will be described below.

As an initial state, the optical reading head 20 in the copying apparatus 10 is arranged on the left side as shown in FIG.

Further, it is assumed that the copying machine 10 is equipped with a cassette containing a tape having a width of 8 mm. Therefore, the slide type switch 45 is set by the user so that the width of the reading area is 7.5 mm. Further, the detachable scale 47 has the opening 14
End face 49a so that the width in the front-back direction becomes 8 mm.
Is mounted on the copying apparatus 10 with the fixed scale 46 facing the side.

In the copying apparatus 10 in such a state, when a specific one line of a plurality of character lines having a vertical width of 3 mm and having a vertical interval of 2 mm, which is expressed on the surface to be read, is to be copied, Arranges the copying apparatus 10 on the reading surface so that the specific character line is arranged at the center in the width direction within the opening 14 having a width of 8 mm in the front-rear direction. At this time, some of the character lines expressed above and below the specific line are also opened.
It may be placed inside.

Therefore, when arranging the copying apparatus 10, the user confirms the image on the surface to be read which is seen through the opening 14, and the specific character line is arranged in the center of the opening 14. It suffices to move 10 so that alignment can be performed easily.

When the switch 13 is depressed in this state,
The copying apparatus 10 drives the motor 36 so that the optical reading head 20 moves along the guide bar 18 along with the copying apparatus 1.
While moving to the right in 0, the light emitting diode 28 is caused to emit light, and the light receiving element 23 reads an image arranged in the center 7.5 mm of the width of the opening 14 in the front-rear direction. In the opening 14 having a width of 7.5 mm, an image of 0.5 mm is arranged in the front-back direction of the image of the specific character line and the character lines that are vertically adjacent to the character line. .

These images are read as analog electric signals by the light receiving element 23, converted into digital signals by the analog / digital conversion device 37, and stored in the storage device 38.

Then, the copying apparatus 10 includes the printing apparatus 40.
As a result, a 7.5 mm wide image corresponding to the data stored in the storage device 38 is printed at the center position of the 8 mm wide tape.

On the tape on which the image thus read is printed, an image of a specific character line is printed at the center position in the width direction of the tape, and the character lines adjacent to the upper and lower sides of the specific character line are also printed. An image of 0.5 mm is printed in the front-back direction near both ends in the width direction of the tape.

Next, when printing the same specific character line on the surface to be read, the detachable scale 47 is temporarily removed from the copying apparatus 10 from the state of the copying apparatus 10 and the width of the opening 14 in the front-rear direction becomes 4 mm. So that its end face 49b faces the fixed scale 46 side.
The operation of the copying apparatus 10 when it is reattached to the printer will be described.

When a specific line on the surface to be read is copied by the copying apparatus 10 in such a state, the specific character line is located substantially in the center of the opening 14 having a width of 4 mm in the front-rear direction. The copying apparatus 10 is arranged so as to be arranged. At this time, when the width of the opening 14 is 8 mm, the character lines adjacent to the upper and lower sides of the specific character line arranged in the opening 14 are hidden by the fixed scale 46 and the detachable scale 47, and the width is reduced. Within the 4 mm opening 14, only certain character lines are placed.

When the switch 13 is pressed in this state,
The copying apparatus 10 has a total width of 7.5 mm of an image inside the opening 14 excluding the width of 0.25 mm from the front side and a white image inside the 3.75 mm wide portion adjacent to the opening 14 of the detachable scale 47. To read. The read image does not include character lines that are adjacent to the upper and lower sides of the specific character line, but includes only the specific character line. Then, the read image having a width of 7.5 mm is printed at the center position of the tape having a width of 8 mm.

On the tape on which the image thus read is printed, only the image of a specific character line on the surface to be read is printed.

Next, a case where a cassette accommodating a tape having a width of 4 mm is mounted on the copying apparatus 10 will be described.

In this case, the slide switch 45
Is set by the user so that the width of the reading area is 3.5 mm. Further, the removable scale 47 has its end face 49b facing the fixed scale 46 side so that the width of the opening 14 in the front-rear direction is 4 mm.
Is attached to.

When a specific line on the surface to be read is copied by the copying apparatus 10 in such a state, the center in the width direction (in the reading area) within the opening 14 having a width of 4 mm in the front-rear direction. The copy device 10 is arranged at a predetermined position on the surface to be read so that the specific character line is arranged on the reading surface. At this time, the character lines adjacent to the upper and lower sides of the specific character line on the surface to be read arranged in the opening 14 are hidden by the fixed scale 46 and the removable scale 47, and the specific character line is inside the opening 14. Only rows are placed.

Accordingly, when the user places the copying apparatus 10 at a predetermined position on the surface to be read, the opening 14
While confirming the image on the surface to be read that can be seen through, the copying apparatus 10 may be moved so that the specific character line is arranged at the center of the opening 14, and the alignment can be performed very easily.

When the switch 13 is depressed in this state,
The copying apparatus 10 reads the image arranged in the reading area in the opening 14. In the reading area (width 3.5 mm), only the image of the specific one character line is arranged. Then, the copying apparatus 10 prints the read image in the reading area at the center position of the 4 mm wide tape.

On the thus-printed tape, only an image of a specific character line is printed at the center position in the width direction of the tape, and the same image as the image in the opening 14 seen through the opening 14 is formed on the tape. To be done. Therefore, the user can surely know the image printed on the tape simply by disposing the copying apparatus 10 at a predetermined position on the reading target surface.

Next, when the width of the reading area is set to 3.5 mm and the specific character line is printed on the tape of 4 mm width, the detachable scale 47 of the detachable scale 47 is adjusted so that the width of the opening 14 in the front-rear direction becomes 8 mm. The operation of the copying apparatus 10 with the end surface 49a facing the fixed scale 46 side and reattached to the copying apparatus 10 will be described.

In this case, the reading area by the copying apparatus 10 is a central portion (width 3.5 mm) except for a width 0.25 mm at both ends of the front half of the opening 14 having a width 8 mm.
Is. Therefore, the user needs to move the copying apparatus 10 in anticipation that the specific character line is arranged in the reading area (about the center of the front half in the opening 14).

It should be noted that 3.5 mm at the opening 14 having a width of 8 mm.
When the specific character line is arranged in the reading area of the width, in the opening 14 having a width of 8 mm, the document line above the specific character line is confirmed in addition to the specific character line. ing.

In such a state, since the opening 14 is large, it is easy to find a specific character line through the opening 14 after the copying apparatus 10 is placed on the reading surface.

When the switch 13 is pressed after the arrangement of the copying apparatus 10 is completed, the copying apparatus 10
Reads the image in the reading area. Then, the copying apparatus 10 prints the read 3.5 mm wide image at the center position of the 4 mm wide tape.

On the tape thus printed, only the image of the specific character line is expressed at the center position in the width direction of the tape.

When copying a character line having a vertical width of 6 mm expressed on the surface to be read, it is 4 mm.
Since those characters cannot be fully expressed on the width tape,
A tape cassette containing 8 mm wide tape is used.

In this case, if the width of the opening 14 in the front-back direction is set to 4 mm, a part of the character line to be copied is always hidden outside the opening 14 and the part is not copied. The end surface 49a of the detachable scale 47 so that the width of the scale is 8 mm.
The detachable scale 47 is attached toward the 6 side.

Then, the width of the reading area is set to 7.5 mm by the slide type switch 45, the character is arranged in the center of the opening 14 in the width direction, and the switch 13 is pressed to change the character line. Printed on the center of the tape. In this case also, since the same image as the image in the opening 14 seen through the opening 14 is formed on the tape,
The user can surely know the image printed on the tape simply by disposing the copying apparatus 10 at a predetermined position on the reading target surface.

As described above, according to the copying apparatus 10 of the present embodiment, since the size of the opening 14 can be changed according to the width of the character (image), the character (image) can be easily copied. The device 10 can be arranged.

Therefore, the image printed on the tape can be known only by disposing the copying apparatus 10 at a predetermined position on the surface to be read.

Further, therefore, according to the arrangement position of the characters on the surface to be read, by removing the character line adjacent to the specific character line in the reading area by the detachable scale 47, only the specific character line is taped. Can be copied on.

Further, one detachable scale 47 is used for 2
Openings 14 of different widths can be formed.

The present invention is not limited to the embodiments described above in detail, and various modifications can be made without departing from the spirit of the invention.

For example, in this embodiment, the case where the width of the opening 14 is 4 mm or 8 mm has been described. However, since there are various widths of characters, the width of the opening 14 should be adjusted to the character width. A removable scale 47 having a width of the opening 14 other than 4 mm or 8 mm may be prepared and the removable scale 47 may be mounted on the copying apparatus 10.

The fixed scale 46 is also attached to the removable scale 4.
As shown in FIG. 7, the opening 14 having four different widths can be formed depending on the mounting state of the fixed scale 46 and the detachable scale 47.
May be formed.

Further, instead of forming the opening 14 by the fixed scale 46 and the detachable scale 47, the opening 14 having a fixed width is formed in one scale, and the scale is detachably attached to the copying apparatus 10. You may do it. In that case, the width of the opening 14 can be changed by preparing a plurality of scales having different widths of the opening 14 and selecting and mounting these scales in the copying apparatus 10.
