DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler which is effective when a typographical error correction tape is used which corrects an erroneous character of a document or the like by transferring an opaque film thereon.

[0002]

2. Description of the Related Art Conventionally, a so-called correction tape is formed by forming an opaque film for correction on a base film and rubbing the back surface of the base film with an appropriate pressure so that the tape can be transferred onto erroneous characters such as documents. Wrapped in the case, stored in the case, pulled out the end of the tape from the outlet, pressed the correction film against the typographical error, and made a correction by pressing the back of the base film using a part of the case And a reel for holding one end of the correction tape and winding the used tape.The tape supply reel and the take-up reel are linked with gears, etc. The correction film is pressed against the typographical error through the rubbing part provided for the rubbing and rubbed. Correction tape feeder has been put into practical use.

[0003]

When erroneous characters are corrected by using such a correction tape supply device, the ends of the transferred correction film are cut irregularly, and correction is not originally required. It often happens that characters are covered. Also, when the correction tape supply device is slid along the rows and columns of the characters, the characters protrude from the rows and columns of the characters that are originally linearly aligned, and, as described above, up to the characters that do not require correction. Covering may occur.

[0004] Such a result is not only poor in appearance, but also on the edge, and when a partially erased character is supplemented with a writing instrument to add a section, the coating for correction is peeled or broken. There is. An object of the present invention is to provide a ruler for a correction tape that does not cover characters that do not require such correction.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a linear ruler for guiding a correction tape supply device to move along an edge, and an edge perpendicular to the linear ruler. A tape cut portion is provided, and the tape cut portion is solved by a correction tape ruler that is formed by gradually reducing the thickness in a tapered shape so that an edge perpendicular to the straight ruler portion has a minimum thickness. You.

[0006] The simplest of such a ruler for correction tape can be solved by providing the tape cut portion at one end or both ends of the straight ruler.

Although it is slightly more complicated than the preceding paragraph, it is easier to use. In the preceding two paragraphs, two parallel edges are respectively defined as the straight line ruler portions, and the tape cut portion is connected to the two parallel straight ruler portions. The problem is solved by providing at each end of the section.

In addition, the linear taper includes a linear ruler for guiding the correction tape supply device to move along the edge, and a tape cut portion having an edge perpendicular to the linear ruler. The problem can also be solved by providing a taper-shaped tapered shape so that an edge perpendicular to the ruler portion has a minimum thickness, and a movable cursor that slides and moves using the straight ruler portion as a guide. .

[0009] In the above-mentioned item, the problem can be solved as a more versatile request by providing a pair of tape cut portions provided with a cursor movable with the linear ruler portion as a guide.

Further, in each of the preceding paragraphs, a more useful ruler for a correction tape can be obtained by attaching a scale on the edge of the straight ruler portion to enable measurement of the length.

Further, in each of the above items, a more useful ruler for a correction tape can be obtained by forming a template used for graphic drawing on the plane portion of the ruler.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is directed to a linear ruler portion serving as a guide when a correction tape supply device is moved along a character string to be corrected, and a clean tape for cutting the correction tape when the correction is completed. The tape cut section is collected as one ruler.

The tape cut portion has an L-shaped projecting edge perpendicular to the straight ruler portion. The edge is thinnest at the end, and has a so-called knife edge shape in which the thickness gradually increases as the distance from the edge increases. By doing so, the cutting of the correction tape at the correction end point can be performed cleanly in a straight line.

Although the tape cut portion may be provided at only one end of the straight ruler portion, the provision of the tape cut portion at both ends makes the correction work efficient. Also, depending on the direction of the L-shaped projection,
It can be used separately for right-handed or left-handed.

The straight ruler may be only one end of the long ruler. However, by making use of two parallel edges and providing tape cut portions at both ends, the correction work can be made more efficient. Also, right-handed and left-handed can be used.

If the tape cut portion is slid by a cursor that guides the straight ruler portion, positioning of the ruler with respect to the character string to be corrected becomes easy. In addition, by providing two pairs of sliding tape cut portions that are symmetrical with respect to the straight ruler portion, the correction start point and the correction end point can be easily set, and the middle between the two points is the straight ruler portion. The work will be extremely efficient.

Further, if the tape cut portion which is slid by the cursor protrudes to both sides with respect to the width of the straight ruler portion, it can be used for both right-handed and left-handed.

Furthermore, if a scale that can be used for length measurement is added to the edge of the straight ruler portion, or a template that is frequently used for drawing a figure by using an excess area of the ruler is provided, the range of utilization of the ruler can be improved. Can be greatly expanded.
