Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double-headed writing instrument in which a writing body for writing with ink is attached to the tip of a barrel and a ballpoint pen refill is attached to the rear of the barrel.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, a double-headed writing instrument is known in which ink or liquid ink occluded in a batting is stored in a barrel as it is, and a felt-tip pen and a ballpoint pen for writing with this ink are connected by a connector.

[0003]

[Problems to be solved by the device]

 However, the conventionally known double-headed writing instruments have drawbacks that the volume of ink to be stored is small and the total length is long, and in addition, the ballpoint pen refill is difficult to replace.

[0004]

[Means for Solving the Problems]

 According to the present invention, the ink or liquid ink occluded in the batting is stored in the barrel as it is, and a writing body for writing with the ink is attached to the tip of the barrel. Moreover, a fixture is tightly fitted to the rear end of the barrel, and a ballpoint pen refill is detachably attached to the fixture. In this way, the object is to provide a double-headed writing instrument that solves the above-mentioned conventional problems.

【Example】

 An embodiment of the present invention will be described with reference to FIG. 1. A shaft cylinder 1 contains a batting 2 containing ink. Moreover, the pen body 3 is fixed to the tip of the barrel 1, the rear part of the pen body 3 is connected to the batting 2, and the capillary action of the pen body 3 guides the ink in the batting 2 to the tip of the pen body 3 for writing. To do. Further, a cap 4 for sealing the pen body 3 is fitted on the tip of the barrel 1. A fixture 5 is tightly fitted to the rear end of the barrel 1 by welding or press fitting. A ball-point pen refill 6 is detachably attached to a storage portion 5A of the fixture 5. Since the structure of the ball-point pen refill 6 has been generally used in the past, detailed description thereof will be omitted. Further, a transparent rear cap 7 is fitted to the rear outer side 5B of the fixture 5. As described above, since the ball pen refill 6 is attached to the storage portion 5A of the fixture 5 that is tightly fitted to the rear end of the barrel 1, the total length of the ball pen refill 6 and the writing body for writing with ink. It is a combination that is not long. Moreover, the ball-point pen refill 6 can be replaced by simply removing the rear cap 7, so that the replacement operation can be easily performed.

Further, in place of the ballpoint pen refill 6, a mechanical pencil or other writing instrument can be easily attached to the fixture 5. Moreover, since the lead of the mechanical pencil is inserted into the inner hole 5C of the fixture 5, a long lead can be used without increasing the total length of the double-headed writing instrument.

Although the above-described embodiment has been described as a felt-tip pen type using a batting as a writing body for writing with ink, it goes without saying that the present invention is not limited to the above-mentioned embodiment. As shown in FIG. 2, a writing instrument in which the liquid ink 8 is directly contained in the barrel 11 can be used in the double-headed writing instrument of the present invention.

[0008]

[Effect of the device]

 As described above, the double-headed writing instrument of the present invention has a simple structure and is capable of combining a writing body for writing with ink and a ballpoint pen without increasing the overall length. In addition, the volume of ink is large, and writing with ink can be performed for a long time, and the ballpoint pen refill can be easily replaced.
