Embodiment Construction

[0024] Next, preferred modes for carrying out the present invention will be described more specifically with reference to the drawings.

[0025] figure 1 It is a longitudinal sectional view of a slide-type compound writing implement. In this example, a composite writing implement having the following members is shown: a first writing body 27 provided with a refill accommodating portion (refill container) 8 for accommodating a refill 9 for a mechanical pencil; The second writing body 28, the three replacement cores 10 have ballpoint pen inks of three colors: red, blue or black. The first writing body 27 and the second writing body 28 of the composite writing instrument are slidably arranged in the barrel 1 . In order to protect the refill, the refill accommodating portion 8 is formed of, for example, metal that is hard to bend and strong in rigidity. The refill 10 is made of, for example, an elongated tube-shaped synthetic resin, and is formed to be more flexible than the ab...

Abstract

A slide type compound writing instrument configured such that a regular 60 mm long pencil lead can be advanced in a shaft tube shorter than normal shaft tubes. A slide type compound writing instrument is provided with a shaft tube (1), writing elements arranged in the shaft tube (1) so that the writing elements can advance and retract and including a writing element (27) provided with a lead containing section (8), a clip base (13) forming a part of the writing elements, sliding in an advancing direction or a retracting direction to advance or retract the lead containing section (8), and having the lead containing section (8) inserted therein, and a tip hole (31) provided in the tip of the shaft tube (1) so as to be offset in the radial direction of the shaft tube to the lead containing section (8) side from the axis of the shaft tube (1) and allowing the tip of the lead containing section (8) or the tip of a refill (10) to project from the tip hole.

Description

technical field [0001] The present invention relates to a composite writing implement capable of writing by selectively advancing or retreating a plurality of writing bodies through sliding operation of a sliding member provided in a shaft cylinder. Background technique [0002] As a conventional slide-type composite writing instrument, it has been proposed that an end portion of a pusher as a sliding member is flexibly joined to a rear end of a lead storage portion for a mechanical pencil (for example, refer to Patent Document 1). [0003] By flexibly engaging the pusher with the lead accommodating portion for a mechanical pencil, the pressing operation of the pusher advances the lead accommodating portion for a mechanical pencil so that the lead protrudes from the front end hole. Due to the flexibility of the joint portion, there is no influence of bending on the side of the refill for mechanical pencil due to the extension operation of the lead, so that the lead does not ...
