Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument such as a mechanical pencil, a ballpoint pen or a compound writing instrument in which a plurality of these are combined, and more particularly to a shaft lid opening / closing mechanism thereof.

[0002]

[Prior art]

 Conventionally, a ball-point pen with a seal stamp is often used. In this ball-point pen with a seal, an accessory storage portion is provided in the shaft head, an ink penetrating seal is slightly accommodated in the accessory storage portion, and a shaft lid is detachably fitted on the shaft head. When using a ballpoint pen, the shaft with a shaft lid attached as a cap can be removed and fitted into the rear part of the outer cylinder of the ballpoint pen, and writing can be done with the pen tip. In addition, the seal can be used by removing the shaft cover.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, since the shaft lid is only detachably attached to the shaft head, there is a problem that the shaft lid is easily lost, and if it is lost, the ink permeates and is contaminated.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the mechanism of the present invention provides a small article storage portion 23 in the shaft head 29 of a writing instrument, opens and closes the small article storage portion 23, and a shaft lid 27 biased in the opening direction by an elastic body 30. , A structure in which an engaged / disengaged portion 27B of the shaft lid 27 is detachably engaged with an engagement / disengagement portion 31 which is pivotally supported on the outer surface of the shaft head 29 and flexibly provided outside the shaft head 29. It is a thing.

[0005]

[Action]

 When the engagement / disengagement portion 31 outside the shaft head 29 is bent by such a configuration, the engaged / disengaged portion 27B of the shaft lid 27 engaged with the engagement / disengagement portion 31 is disengaged, and the shaft lid 27 is removed. Since it is pivotally supported on the outer surface of the small member 29, the small item stored in the small item storage portion 23 can be used by being rotated by the elastic force of the elastic body 30 and opened. After the accessory is used, the shaft cover 27 is rotated against the elastic body 30 to engage the engaged / disengaged portion 27B with the engagement / disengagement portion 31 on the outside of the shaft head 29, so that the accessory storage portion 23 is moved to the shaft lid 27. You can close it with.
