Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a writing instrument having a structure in which a cap is fitted into the writing instrument.

(Problems to be solved by conventional techniques and inventions) Conventional writing instruments of this type have been left in a state where the cap and the writing body are not completely fitted, that is, the seal is incomplete, and the pen is damaged. Volatilization of ink from the tip and air holes caused problems such as blurring of writing and the inability to write. Therefore, with the present invention, if the cap and cursive are not fully fitted, an alarm device will be activated to issue a warning, and the user will be alerted and can correct the cap's fit, thereby solving the above problem. The purpose is to provide a writing instrument that can prevent this from occurring.

(Means for Solving the Problems) The writing instrument of the present invention devised to solve the above-mentioned problems has a writing instrument in contact with a writing body 6 inside a cap 1 containing a battery 11 and an alarm device 3, and a shaft. A contact plate 9 is integrally attached to the inner cover 7, and the contact plate 9 is attached to the battery 1.
1 is interposed between the contact spring 13 of the alarm device 3 and the contact portion 5 of the alarm device 3, and the contact plate 9 is brought into contact with the contact portion 5 when the cap 1 and the writing body 6 are not fitted or in an incompletely fitted state. A spring 1 that biases the inner lid 7 and the contact plate 9 to activate the alarm device 3.
0 is attached and the cap 1 is completely fitted in a predetermined position on the front end or rear end of the writing body 6, and the contact plate 9 interlocks with the inner lid 7 that slides in contact with the writing body 6.
This is characterized in that the contact portion 5 and the contact plate 9 are separated from each other due to the displacement of the alarm device 3, thereby stopping the operation of the alarm device 3.

(Embodiment) In the illustrated embodiment, an alarm device 3 is mounted inside an inner wall 2 provided at the innermost part of a cap 1, and a conductive part 4 of the alarm device 3 is passed through the outside of the inner wall 2 to form a ring-shaped alarm device. The contact part 5 is installed in contact with the outer surface of the inner wall 2, and then the inner lid 7, on which the front end or the rear end of the writing body 6 comes into contact, is slid in the axial direction along the inner wall of the alarm device 3. The base end of a rod shaft 8 that passes through the center hole of the inner wall 2 is fixed to the center of the rear wall of the inner lid 7, and the tip of the rod shaft 8 that protrudes outside the inner wall 2 has a disk shape. A contact plate 9 is attached, and a coil spring 10 is interposed around the rod shaft 8 between the rear wall of the inner cover 7 and the inner wall of the inner wall 2, and the inner cover 7 is biased forward. Connect the plate 9 to the contact part 5 of the alarm device 3
A holder 12 containing a battery 11 is fitted into the inner diameter part of the rear end of the cap to hold the battery 11 in contact with the cap.
A contact spring 13 is interposed between the front surface of the contact plate 1 and the contact plate 9. Here, the inner lid 7 is the cursive 6
is inserted correctly into the predetermined position at the front end of the cap 1 (when the opening edge 14 of the cap 1 is in contact with the stepped portion 15 of the writing body 6), the contact plate 9 will slide.
The contact portion 5 is configured to be pulled away from the contact portion 5.
Further, the rear end of the battery 11 is energized from the holder 12 through the cap 1 to the contact portion of the other pole of the alarm device 3. As shown in FIGS. 3 and 4, the writing body 6 has a shape that allows the rear end to be inserted into the cap, and the rear end surface has a hooking step that can come into contact with the opening edge of the inner lid 7. 16, and when the cap 1 is fitted in the correct position (opening edge 14 of the cap 1
is in contact with the step 15' at the rear of the writing 6)
The engaging stepped portion 16 is configured to press and slide the inner lid 7 to separate the contact plate 9 from the contact portion 5.

(Function) In the writing instrument of the present invention, the cap 1 may not be fitted into the writing body 6, or the cap 1 may be completely fitted into the writing body 6 at a predetermined position as shown in FIG. When the contact spring 13 and the contact plate 9 are not

is issuing a warning. However, when the cap 1 is completely fitted into the predetermined position at the front and rear ends of the writing body 6, the contact plate 9 and the contact portion 5 are separated from each other as shown in FIGS. 1 and 3, and the alarm device 3 alarm will stop. Therefore, the user can immediately recognize whether or not the cap 1 and the writing body 6 are completely fitted, depending on the presence or absence of an alarm from the alarm device 3. Note that when writing, it is necessary to remove the cap 1 from the front end of the cursive body 6, and there is a concern about the noise caused by the alarm while writing. If the alarm device 3 is placed in a fixed position, the alarm device 3 is stopped, so there is no need to worry about noise.

(Effects of the invention) The present invention is as described above, and if the cap is not properly seated in the predetermined position at the front end of the cursive writing body, the alarm device will issue an alarm, and the user will be alerted and write the cap. This allows the cap to fit correctly in a predetermined position on the body, thereby completely sealing the cap, suppressing volatilization of ink from the pen tip and air holes, and preventing deterioration in writing performance. Further, when writing, if the cap is placed on the rear end of the writing body, the alarm device will not be activated, so it is a perfect measure against noise. Furthermore, since the alarm device continues to sound when the cap is removed from the writing body, the user is expected to keep the cap attached to the writing body at all times, which is extremely effective in preventing loss of the cap.
