Abstract

PURPOSE:To simply and accurately draw a predetermined line, etc., without vibrating a pen body by arranging a rotary plate to be driven by a motor in a housing, and moving an operating shaft mounted with a pin by engaging it with the plate in a conical motion around a fulcrum. CONSTITUTION:A motor 2 and a rotary plate 3 to be driven by the motor 2 are arranged in a housing 1. At least one or more of an eccentric hole 3a, an eccentric long hole 3b, an eccentric arc long hole, an eccentric groove and an eccentric pin is formed at the plate 3. Further, an operating pin 4a, an operating groove are rotatably engaged with the holes or the groove. On the one hand, a pen 6 is mounted at an operating shaft 4. A fulcrum P is arranged at the shaft 4 to allow a conical motion G. On the other hand, clips 9 are detachably mounted on and underneath the housing 1 so that the pin 4a, etc., and the fulcrum P are elastic. Thus, a predetermined elliptical line, a zigzag line, etc., can be simply and accurately drawn without vibrating the pen body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric pen for writing by electrically rotating a pen tip.

[0002]

2. Description of the Related Art Conventionally, an unbalanced weight composed of an eccentric weight is rotated by a motor on the upper part of a housing to sway the housing body, and a pen tip is used to draw lines that come and go in zigzag lines while gripping a hand.

[0003]

This has the following drawbacks. (I). It is difficult to draw because the body shakes. (B). Because it is drawn with the grip of the hand, it is difficult to draw a line of a certain size. (C). Since the main body shakes, it is impossible to draw a straight and precise rounding line using a ruler. The present invention has been made to eliminate these drawbacks.

When engaged, the actuating shaft (4) causes a conical movement around the elastic fulcrum (P), and the pen tip rotates, so that a line, an elliptical line, or a zigzag line can be drawn that makes the arm pressure and tilt. . Then, the operation pin (4a) or the operation groove (4b) is provided with an eccentric hole (3a), an eccentric elongated hole (3b), and an eccentric arc elongated hole (3).
e), eccentric groove, or eccentric pin (3c), or by changing the conical momentum changing means by switching the rotation direction of the motor (2), large and small rolling lines, elliptical lines, and zigzag lines. Can be withdrawn. By attaching the clip (9) to the lower part of the main body, a straight round and round line, an elliptical line or a zigzag line can be drawn using a ruler.

The operating pin (4a) is provided with the operating shaft (4), the pen (6) is detachably fastened with the nut (7), and the fulcrum (P) is provided below the operating shaft (4). Coil spring (5)
It has a protrusion (11) so that it can be elastically moved. A rubber ring (5) can be considered instead of the coil spring (5). FIG. 5 shows an operating pin (4a) penetrating an eccentric hole (3a) through a rotary plate (3) provided on a drive shaft (2a).
However, the clearance fits in with a margin, and the operating shaft (4) represents conical movements (G) and (G1) around the fulcrum (P). 6 to 8 show an eccentric hole (3a), an eccentric elongated hole (3b), an eccentric arc elongated hole (3e), an eccentric groove, and an eccentric pin (3c) in a rotary plate (3) rotatable by a motor (2). 1 for mixing
Vibration can be reduced by providing one or more balancers (3d). FIG. 8 shows that the eccentric circular arc elongated hole (3e) is used to drive the conical momentum varying means around the fulcrum (P) about the operating shaft (4) from the relationship of the switches (A, B, C) shown in the wiring diagram. It can be operated by switching the rotation direction in (2). In the embodiment shown in FIGS. 9 and 10, FIG. 9 is a sectional view and FIG. 10 is a perspective view of a main portion, in which the operating groove (4b) is rotationally engaged with the eccentric pin (3c) and the operating shaft (4 ), Screw the holder (4b) into and remove it,
