Description

[Detailed description of the invention] Conventionally, as shown in FIG. 3, the tail pin 1 of the scriber is inserted into the linear guide groove 8a of the template 8
Also, the tracing pins 3 are slidably engaged with the characters or symbols 8b engraved on the template, and the lower end of the adjusting screw 12 screwed into the scriber body 10 is brought into contact with the paper surface 13 on the desk. Lettering sets that perform lettering with a cylindrical pen 5 removably attached to the tip of the scriber body are generally available on the market, but they are designed to be used by right-handed people, so left-handed people cannot use them. hard.

The object of the present invention is to provide a lettering set for right-handed people and an aid that allows left-handed people to easily perform lettering.

The present invention has a hole 2 through which the spherical head mounting screw 1a at the upper end of the tail pin 1 of the scriber passes, and a hole 4 through which the head 3a of the trace pin 3 of the scriber passes.
and the scriber knob 6 with respect to the center line A-A connecting the cylindrical pen 5 and the tracing pin 3 of the scriber.
and a picking arm 7a protruding to the opposite side,
A rod-shaped member 7 that can be attached and detached from the scriber is combined with a weight 9 that is detachably screwed onto the spherical head mounting screw 1a and brings the tail pin 1 into contact with the template 8 with a pressure that can be substantially lettered. It is characterized by

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The rod-shaped member 7 is formed by cutting a transparent plate made of hard plastic into a shape that does not interfere with the scriber knob 6, as shown in FIG.
-Protrudes approximately at right angles to A. The hole 4 has an inner diameter into which the tracing pin head 3a fits. Also, in order to adjust the inclination of the lettering characters, the base of the trace pin support arm 11 is fixed on the scriber body 10 with a set screw 14 so as to be rotatable about point 0, so that the hole 2 is The rod-shaped member 7 is formed into an elongated hole in the longitudinal direction so as to allow rotation of the trace pin support arm relative to the scriber body.

The weight 9 is circular, and has a small cylindrical portion 9a at the lower end thereof with a female screw thread that engages with the mounting screw 1a of the spherical head 15 (FIG. 3).
has an outer diameter that fits into the elongated hole 2 in a slidable manner. The weight of the weight 9 is determined by supporting the scriber at three points on the desk via the tail pin 1, trace pin 3, and adjustment screw 12 as shown in Figure 3, since a right-handed person pinches the scriber knob 6 to do lettering. The setting is made so that a pressing force at least equal to the pressing force that acts on the tail pin 1 when the tail pin is pressed is applied to the tail pin.

Since the present invention has the above-mentioned configuration, by fitting the mounting screw 1a with the spherical head 15 removed and the tracing pin head 3a into the holes 2 and 4, respectively, and screwing the weight 9 into the mounting screw 1a, the rod can be fixed. If the shaped member 7 is attached to the scriber as shown, the template 8
Since the contact pressure of the tail pin 1 against the linear guide groove 8a is applied by the weight 9, a left-handed person can pinch the tip of the picking arm 7a of the scriber that is engaged with the template 8 in the conventional manner.
Lettering can be easily done with the cylindrical pen 5.

In the illustrated embodiment, the rod-like member 7 is made of a transparent plate so that the characters or symbols 8b of the template 8 can be seen through during lettering and the characters or symbols 8b can be easily traced by the tracing pin 3. The reason why the knob arm 7a of the shaped member is made to protrude from the perforated part of the hole 4 at a substantially right angle to the center line A-A is to make it easier to see the part of the trace pin 3 that engages with the letters 8b, and to The picking arm 7a is positioned substantially on the center line B-B connecting the tracing pin 3 and the adjusting screw 12 or the cylindrical pen 5 is prevented from floating when a pressing force is applied to the picking arm inadvertently. This is to do so.

According to the present invention, since the contact pressure of the tail pin 1 with the template 8 is substantially ensured by the gravitational action of the weight 9, a left-handed person can use the picking arm 7a.
This has the effect that lettering can be easily done by operating the lettering set for right-handed people.
