Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a writing instrument holding device for an automatic drawing machine.

2. Description of the Related Art Automatic drawing machines are known in which a writing instrument is held in a carriage that moves in a predetermined direction, and the writing instrument is moved together with the carriage to draw a drawing.

In this automatic drawing machine, when drawing, the writing instrument is lowered and the writing part is pressed against the paper, and the writing instrument is moved while applying pressure, and when not drawing, the writing instrument is raised and the writing part is moved away from the paper. ing.

Problems to be Solved by the Invention There are two types of writing instruments, as shown in FIGS. As shown in Figures a and b, the tip holder 4 holding the writing part 3 is relatively pushed into the writing instrument main body 1 to apply writing pressure.

For this reason, in the case of the former writing instrument, it is necessary to fix the writing instrument main body 1 and hold it so as to push the upper protrusion 2, and in the case of the latter writing instrument, it is necessary to hold the writing instrument main body so that it can move up and down. Two types of writing instrument holding devices are required.

Therefore, an object of the present invention is to provide a writing instrument holding device for an automatic drafting machine that can hold two different types of writing instruments.

Means and operation for solving the problem The first and second holders are provided in the carriage so as to be movable up and down, a vertical movement mechanism is provided to move the second holder up and down, and a regulating member is provided to regulate the lower limit of the first holder. The upper protruding body held by the second holder can be pushed into the writing instrument main body held by the first holder and writing pressure can be applied to the writing part by providing it detachably and regulating the lower limit of the first holder with the regulating member. By removing the regulating member, the main body of the writing instrument can be lowered further after the writing portion contacts the paper to apply writing pressure.

Embodiment A guide 4 of a first holder 3 is provided at the bottom of a guide rail 2 provided on the front surface of the carriage 1 so as to be movable up and down, and a guide 6 of a second holder 5 is provided at the top so as to be movable up and down. A vertical movement mechanism (not shown) such as a pinion, rack, or cylinder driven by a motor is attached between the carriage 1 and the second holder 5, and between the carriage 1 and the first holder 3, a vertical movement mechanism (not shown) is installed. A regulating member for regulating the lower limit position, for example a stopper 7, is detachably attached. Note that the carriage 1 and the guide 4 may be connected with bolts to form a regulating member.

First and second switches 8 and 9 are attached to the sides of the carriage 1, and a dog 10 is integrally formed on the guide 6 so that the upper and lower limits of the second holder 5 can be detected.

The first holder 3 is vertically elongated and has a substantially U-shape in plan so that it can firmly grip and fix the main body 21 of the writing instrument 20, and the second holder 5 has a bifurcated fork 5a, and the upper part of the writing instrument 20 is It is inserted between upper and lower flanges 23 and 24 formed on the protruding body 22.

Note that the first and second holders 3 and 5 may be connected to the main body 21 and the upper protrusion 22 by a clip type or a bolt.

In the case of a writing instrument that applies writing pressure by moving the upper protruding body 22 up and down to project the writing part 25 from the lower part of the writing instrument main body 21, the writing instrument 20 is held as shown in FIG. When the second holder 5 is lowered, the first holder 3 and the second holder 5 are simultaneously lowered until the first holder 3 comes into contact with the stopper 7, as shown in FIG. Holder 3 is stopper 7
Since the upper protruding body 22 does not come into contact with the writing instrument body 21 and descend, the upper protruding body 22 descends with respect to the writing instrument main body 21, protrudes the writing part 25, and applies writing pressure.

At this time, since the second switch 9 of the dog 10 is turned on, the application of pen pressure can be detected from the ON signal.

When the second holder 5 is raised from the state shown in FIG. 2, the writing instrument 20 returns to the state shown in FIG.
is separated from the paper, the first switch 8 is turned on by the dog 10, and the writing part 25 is turned on by the ON signal.
It is possible to detect when the paper is separated from the paper.

In addition, in the case of a writing instrument that applies writing pressure by relatively pushing the tip holder 26 provided with the writing part 25 into the writing instrument main body 21, the writing instrument 20 is held as shown in FIG. 1, and the stopper 7 is removal,
When the second holder 5 is lowered, the upper protrusion 22 is fixed to the writing instrument main body 21, so as shown in FIG. 26 is relatively pushed into the writing instrument main body 21 and writing pressure is applied.
At this time, since the second switch 9 of the dog 10 is turned ON, the application of pen pressure can be detected from the ON signal.

Effects of the invention The first holder 3 holds the writing instrument main body 21, the second holder 5 holds the upper protrusion 22, the regulating member is attached to regulate the lower limit position of the first holder 3, and in this state By moving the second holder 5 downward and moving the upper protrusion 22 downward, the lower limit position of the writing instrument body 21 can be regulated and the upper protrusion 22 can be pushed into the writing instrument body 21, and the first holder 3 to hold the writing instrument main body 21, and the second holder 5 to hold the upper protrusion 22, and remove the regulating member so that the first holder 3 can be moved below the lower limit position, and in this state, the second holder 5 move the upper protruding body 22 downward.
By moving the writing instrument body 21 downward, the writing instrument main body 21 is lowered together with the first holder 3, and after the writing part 25 comes into contact with the paper, it can be further lowered.

Therefore, the upper protrusion 22 is connected to the writing instrument main body 21.
A writing instrument, such as a writing instrument that applies writing pressure by pushing it in, such as a pencil, or a writing instrument that applies writing pressure by pushing the lower holder 26 holding the writing part 25 relatively into the writing instrument main body 21, such as a normal ballpoint pen, can also be used. You can draw by holding it and applying pressure.
