Description

[Detailed description of the invention]

[0001] The present invention relates to a writing instrument capable of drawing staffs at equal intervals at a time.

[Prior Art] Conventionally, unless a sheet or blackboard on which a staff is preliminarily drawn is used, it is necessary to draw the staff one by one in order to write notes. This was not only a time-consuming and cumbersome task, but it was necessary to draw as many as five equally spaced lines so that the note positions would be clear, unless a ruler was used.

[Problems to be Solved by the Invention] When drawing a staff by hand, the fact that individual lines are “equally spaced” rather than “straight lines” means that the musical notes to be put on them are It is important to note. In other words, the musical note is important in terms of its pitch, its vertical position on the staff and its vertical position with other codes, and its length is its horizontal distance with other codes. There is no need to dare to make an example, but for example, the work of composer George Crum, "The Magic Circle of Infinity," from Makrok osmos I, is a circle in which all staffs used in the music are drawn in a circle. Is one of the reasons to support this. In other words, if the distance between the five lines is fixed equally to the side of a single writing instrument in advance, even if there is no staff paper or a board with a staff, a staff that can easily and easily put musical notes can be created. Can be subtracted. In the past, it was promised to draw a “straight line” using a ruler, but from the grounds described above, this makes it easier to understand the relative positional relationship between notes vertically and horizontally. It is the opposite condition to draw a staff easily. Of course, it is well known that two pairs of triangles can be used to draw exactly five parallel lines, but the length of the triangle itself is limited. If so, the time and effort spent on it can be uneconomical. However, the trouble and difficulty of drawing staffs one by one without relying on a ruler may have been experienced by anyone learning music. From another point of view, as a problem that can be solved by the present invention, if it is necessary to describe music mainly composed of characters (for example, notes for music and music history, notes, etc.), The staff is often shown as "staff", so if you use a staff paper or board on which the staff is drawn in advance, the staff itself gets in the way and it becomes troublesome to write the characters themselves. In addition, writing characters and text on a staff paper or board on which staff is drawn wastes space because the staff is avoided in order to make the characters themselves easier to see. By using this writing instrument, it is possible to easily place music in the required space in an appropriate place, eliminating the need to rely on paper or boards on which the staff is drawn in advance. In other words, the problem to be solved by this invention is to provide a writing instrument that allows anyone to quickly and easily draw staves at even intervals, in which easy-to-read notes can be placed with a single action.

[Means for Solving the Problem] A writing instrument according to the present invention has solved the above-mentioned problems and is as follows. The writing implement according to the present invention is a staff writing pen with five equally-spaced and fixed drawing points (1) so that it is possible to draw equally spaced staves in one operation. Also, the five drawing points (1) can be replaced with five independent brushes, which can be detached, and the staff (2) can be attached and fixed at regular intervals and in parallel. This is a device that satisfies the means of solving the problem as well. As a writing instrument for drawing a staff, the underlying writing medium varies depending on the place and the situation. This is similar to writing letters, but should be able to be accommodated, for example, depending on the required width of the staff and the required thickness of the individual lines. Ballpoint pens, felt pens, mechanical pencils, pencils, chalk, etc. are fried. Ballpoint pens, felt-tip pens, and mechanical pencils can be applied to those provided with five drawing points (1) in advance. As a frame (2) for attaching five independent brushes and fixing them at equal intervals and in parallel, for the staff writing pen, ballpoint pens, felt pens, mechanical pencils, pencils, chalks, etc. All writing media will be applicable.

[Action] The staff writing instrument according to the present invention is used as follows. This staff writing pen can be run on paper or a board in a direction almost perpendicular to the straight line connecting all five dabs (1) fixed in parallel. Although it was stated that the condition that the five lines drawn are “equally spaced” is more important when writing notes to be placed on them, if a ruler is applied to this writing instrument, a straight line is used. It goes without saying that five parallel lines consisting of are drawn easily and quickly.

Embodiment 1 Embodiment 1 FIG. 1 is a perspective view showing Embodiment 1. In the case of the first embodiment, the medium for writing was performed using a ball-point pen, a felt-tip pen, or a mechanical pencil. In the case of ballpoint pens and felt pens, a cap (3) is required to cover the five drawing points (1) in order to avoid storage of ink and contact with other objects when not in use. With a mechanical pencil, the presence or absence of the cap (3) is not important. The knock part is omitted in the figure.

Second Embodiment FIG. 2 is a perspective view showing a second embodiment. In the second embodiment, the five writing points (1) are replaced with five independent brushes, which are detachable, can be fixed at regular intervals, and are fixed in parallel. Yes, it can be easily attached using a frame made of rubber or plastic material (2). In this case, all media for writing can be applied.

Third Embodiment FIG. 3 is a perspective view showing a third embodiment. In the third embodiment, the medium for writing was performed with a ballpoint pen, a felt pen, and a mechanical pencil, which is an improvement of the first embodiment. However, if the writing medium is a mechanical pencil, the presence or absence of the cap (3) is not considered. The knock part is omitted in the figure. In the third embodiment, a slope A (4) is provided on one side of the writing instrument so that a constant angle with respect to the paper surface can be always maintained when the staff is drawn. If a staff is drawn while the side having the slope A (4) is in contact with the paper surface, a uniform pressure is applied to each of the five drawing points (1), so that the uniformity of each line is obtained and the stability is obtained. With the increase in power, the painter can draw attention mainly to the direction in which the staff is drawn, and can draw more easily.

Fourth Embodiment FIG. 4 is a perspective view showing a fourth embodiment. The fourth embodiment is a modification of the third embodiment. In the third embodiment, the slope A (4) is provided on one side of the writing implement, but the slope B (5) is also provided on the other side. In the case of the third embodiment, when drawing a staff, pressure from one side is always applied to the entire writing instrument. In the fourth embodiment, however, since the writing instrument is not set upside down when drawing, the writing point is not applied. The pressure is dispersed every use, and the durability of the writing implement itself is increased as compared with the fourth embodiment. In addition, the user does not need to be aware of the front and back of the writing instrument body when using it, making the task of drawing a staff more smooth.

Fifth Embodiment FIG. 5 is a perspective view showing a fifth embodiment. The fifth embodiment is a modification of the fourth embodiment. In the fifth embodiment, the tip of a writing instrument that comes into contact with the paper surface is rounded, and the five projecting dots (1) are buried and inserted. Is arranged.

[Effects of the Invention] By using the staff writing instrument according to the invention, anyone can quickly and easily draw staffs at equal intervals with a single operation. In addition, as mentioned in the section [Problems to be solved by the invention], it is necessary to describe music mainly composed of letters (notes and notes for music and music history). In this case, the staff is often shown as “staff”, so if you use a staff paper or board on which the staff is drawn in advance, the staff itself gets in the way and it is troublesome to write the characters themselves. Become. In addition, writing characters and text on a staff paper or board on which staff is drawn wastes space because the staff is avoided in order to make the characters themselves easier to see. By using this writing instrument, it is possible to easily place music in the required space in an appropriate place, eliminating the need to rely on paper or boards on which the staff is drawn in advance. In reality, the goal of the drawer of the staff should be to write "notes" instead of "the staff" itself. The premise is that the time and effort spent in the process of drawing as many as five lines each at equal intervals should be reduced to make the task of writing notes smoother, that is, to achieve that purpose. It is quick and easy to fill, and as a result the effect of reducing the mental hassle of the note writer is reduced. In addition, since the dabs are guaranteed to be equally spaced, it is possible to write musical notes (scores) that are easy to grasp visually on the staff.
