An eraser can be extended by rotation of a cap relative to the middle barrel section. The implement includes the following resin molded components, namely, a guide cylinder, front barrel section, cylindrical cam, middle barrel section, cap, and an eraser guide sleeve. The front half portion of the guide cylinder is fixed to the front barrel section and is attached rotatably in its rear half portion to the middle barrel section. The guide cylinder contains a plurality of writing elements fit in respective grooves and movable axially. The cylindrical cam is attached rotatably into the rear end of the guide cylinder, and is disposed in the middle barrel section, locked from relative turning.

Abstract: In a writing utensil according to the present invention, when a rearward outer cylinder is rotated in either direction, a cam engaging projection, which is integral with the rearward outer cylinder, slides pressingly on either of the respective cam surfaces of first and second sliders. This causes one of the first and second sliders to advance, which in turn causes a first of the first and second refills to project forwardly while the other remains retracted. Similarly, when the rearward outer cylinder is rotated in the opposite direction, the cam engaging projection slides pressingly on the other of the cam surfaces of the first and second sliders. This causes advancement of the other of the sliders, and in turn causes the second of the first and second refills to be projected while the first remains retracted. The construction allows these operations to be smoothly, stably and positively performed.

Abstract: A writing utensil for three different leads is provided in which due to the use of a special front part and a pusher housing being easily insertable into the same, a conventional writing utensil with only one lead can be converted in a simple and robust fashion to a three-color writing utensil. The pusher housing loosely inserted into the shaft housing, which supports the leads, has a profiled contour and can tilt freely into one of several predetermined tilting positions under the effect of gravity and as a function of the rotary position of the shaft housing in order to bring a selected lead into a ready position from which it can be displaced into the writing position.

Abstract: A writing instrument in the form of a ball pen has two cartridges capable of being alternately moved into the writing position by rotating the barrel. A provision is made for a space in the top part of the barrel for accommodating or receiving various accessory devices such as stamping mechanisms, marker pens or the like. The invention includes a guide tube housed within the barrel and having two longitudinal slots therein. Two slides having small tubes for receiving the writing cartridges, are movable back and forth on offset guide rails on the guide tube. The slides are forced into contact with a curve switching cam surface of a switching casing by springs. By rotating the switching casing, the one or other slide and thus the small tubes with the writing cartridges inserted therein are alternately pushed toward the bottom of the writing instrument and into the writing position.
