A writing instrument has a gripping tube rotatably fitted on a front portion of a barrel. At the front portion of the barrel, plural identifying marks having different identification characteristics, such as color, are disposed in parallel in a circumferential direction of the barrel. A window portion is provided in the gripping tube through which is visible an identifying mark selected by rotating the gripping tube relative to the barrel. When the user rotates the gripping tube to the position where the chosen color is visible through the window portion, a locking pawl on the barrel engages with a locking groove at the rear end of the gripping tube to lock the gripping tube in this position. Once locked in position, the gripping tube cannot accidentally rotate thereby preventing a change of colors appearing at the window portion even if the writing instrument is subjected to shock or vibration.

A mechanical pencil has a main body housing a lead-feeding mechanism which includes a chuck and a clamping ring. A tapered member is provided at a front end of the main body, and a slider is mounted to undergo back and forth movement within the tapered member. A lead protection pipe protrudes from a front end of the tapered member when the slider moves forward, and an outer pipe is provided at a front end of the tapered member and surrounds a front end of the lead protection pipe. The slider moves backward as the writing proceeds so the lead protection pipe is not bent by a writing pressure, whereby a lead can be fed by a few knocking operations. The outer pipe is fixed to the tapered member or provided on an outer pipe holder inserted into the tapered member. The outer pipe holder is fixed to the inside of the tapered member or disposed to move back and forth in the tapered member.

A knocking-type writing instrument has a writing refill, such as a pencil lead or an ink cartridge, that is advanced by knocking a knocking member, and an eraser held by an eraser holder disposed at a rear part of the knocking member. When the writing instrument is inclined so that the eraser side faces downward, a control pin provided in the eraser holder and a movable stopper drop by their own weights along a sliding groove of the knocking member. When the control pin drops a predetermined distance and enters a circumferential locking groove provided at a rear end of the sliding groove, detachment of the control pin is prevented by the stopper, and the eraser holder is unable to retract to the inside of the knocking member. In this state, a radial projection on the control pin abuts a rear end face of the knocking holder, whereby the knocking member is locked and can no longer be knocked, and feeding of the writing refill is prevented.

A rotary feeding mechanism for axially feeding a rod-shaped body from a main body by rotating a tapered tip has a simple structure and can be produced economically. The main body is provided with plural open windows are arranged at a predetermined thread pitch along an axial direction of the main body. The tapered tip is installed rotatably on the main body, and a guide pipe extending toward the inside of the main body is fixed to the tapered tip. A holder for holding the rod-shaped body is housed in the main body, and the holder and the guide pipe are connected non-rotatably and movably in the axial direction. The outer periphery of the holder has an external thread which engages with the windows so that when the tapered tip is rotated, the holder moves in the axial direction while rotating via the guide pipe, and the rod-shaped body can be projected from or retracted into the main body.

[Problem] To address the problem wherein, when employing a conventional actuator using a piezoelectric element as a general-purpose mechanism component such as a linear actuator or an electric cylinder, the movement direction thereof is not guided or the movement direction thereof is inadequately restricted, and thus the movement direction of the moving body changes and the orientation thereof is changed or rotated by an external force. [Solution] An output shaft, which comprises a rectangular-cuboid shape having a piezoelectric element attached to one end thereof, and which exhibits high rigidity, high thermal conductivity and excellent lubrication properties, is immobilized on a guide member by a restriction member so as to be confined to one degree of freedom. As a result, a linear actuator, an electric cylinder, and a force generator which can be used for general purposes, and which exhibit excellent rectilinear movement can be achieved. Furthermore, an output member having a mass corresponding to the mass of the piezoelectric element is attached to the other end of the output shaft, and thus the force generated, durability and usability are improved.

Provided is a label feeding device that is capable of efficiently peeling and feeding linerless labels one by one, said linerless labels comprising multiple labels that are arranged, without using release paper, such that each label is bonded to the surface of a label thereunder at an overlapping section while being displaced from the lower label at a displaced section. The labels are moved by means of a conveyor (8) that has on a surface thereof protrusions or grooves to which the labels are tentatively attached, and the conveyor bends at a peeling part (9), thereby peeling off the displaced section (5) of the upper label from the conveyor. A slider (13) that presses the lower label against the conveyor surface is movably disposed at the peeling part, thereby preventing the lower label from being peeled off from the conveyor. The displaced section projecting from the conveyor is pinched by a claw mechanism (12) and carried to a label ejection slot (11).

Provided is a capacitive stylus which has, at the tip, an electrically conductive pad that has been made less deformable and that recovers the original shape immediately when the electrically conductive pad is released from a screen. A stylus body (1) has an electrically conductive core (4), and the electrically conductive core (4) has a hollow electrically conductive pad (7) at the tip. At an outside peripheral portion, the electrically conductive pad (7) engages with a pad holder (10) and a closing unit (11). The electrically conductive pad (7) accommodates a pressing body (12) in the inside. The pressing body (12) presses the inner surface of the electrically conductive pad (7) toward the outside by using a spring (13). Even if the electrically conductive pad (7) has a depression, the electrically conductive pad recovers the original shape immediately due to the pressing body (12).
