Abstract

PURPOSE:To enable the operation of a pen-shaped thermal printing device just like a pen by mounting a print timing detection means and a thermal head at the tip of a pen-holder with a thermal print ribbon cassette mounted detachably. CONSTITUTION:When using a thermal printing device, a pen-holder 1 is held as it is an ordinary pen and a thermal print ribbon 13 and both rollers 9 and 10 are moved horizontally over a paper 17 to the right or left under being lightly pressed thereon 17. With the rotation of a print timing detection roller 9, a print timing pulse signal is inputted into an external controller corresponding to the rotational speed thereof and synchronizing this signal, a required code signal is outputted from the controller into a thermal head 4. As the pen-holder 1 is moved, a specific character is thermally transferred onto the paper 17 at a fixed interval regardless of the speed of the pen-holder 1.

Description

[Detailed Description of the Invention] The present invention relates to a thermal printing tool, and proposes a novel thermal printing tool that is shaped like a pen and can perform thermal printing by simply holding it with one hand and moving it on a paper surface. .

That is, the uninvented thermal printing tool has a thermal head and a print timing detection means that can obtain a print timing signal corresponding to the movement on the paper surface attached to the tip of the pen shaft. It is characterized in that a printing ribbon cassette is detachably attached.

In the following, the invention will be explained in detail with reference to the illustrated embodiments.

As shown in Fig. 1, this thermal printing tool is equipped with a thermal printing mechanism at the tip (lower end) of the pen shaft 1, which has a diameter of 9 lengths and is suitable for holding with one hand, and is suitable for holding with one hand. It can be operated with one hand as if it were a handheld device.

That is, as shown in FIG. 3, a thermal head 4 having a flange 3 is fitted into a head hole 2 formed on the tip end surface (lower end surface) of a pen shaft l so as to be freely retractable. , a spring 6 arranged in the spring chamber 5 following the head hole 2
It is urged outward (downward) by. Due to this bias, the collar 3 of the thermal head 4 comes into contact with the stepped portion 7 between the head hole 2 and the spring chamber 5, so that only the tip of the thermal head 4 protrudes outward from the head hole 2. There is.

The thermal head 4 is electrically connected to an external control device (not shown) via a lead wire 8 drawn out from the upper end of the pen shaft 1, and is automatically controlled by this.

Further, two rollers 9 and 10 are pivotally supported on both left and right sides of the tip edge of the pen shaft 1, one for detecting printing timing and the other for assisting the printing timing.

The print timing detection roller 9 has a built-in or attached pulse generator. When this roller 9 rotates, the pulse generator outputs a pulse (print timing signal).
This is inputted to the control device via the lead wire 11.

Furthermore, a thermal printing ribbon cassette 12 is attached to the tip of the pen barrel 1 in a manner that can be freely increased.

That is, this cassette 12 has thermal printing ribbon 1.
A pair of ribbon reels 14, 14'k are arranged on the left and right sides of one side of the side plate 15, and these left and right ribbon reels 14,
A pair of left and right elastic clamping pieces 16, 16 are protruded from one side of the side plate 15 between 14 and 14. By holding the tip of the pen barrel 1, it can be detachably attached to the pen barrel 1. In this surface state, the thermal printing ribbon 13 is located below the thermal head 4.

Therefore, in order to use a non-thermal printing tool, hold the pen shaft 1 like a normal pen as shown in FIG.
17 (Fig. 3) and move it horizontally from left to right or vice versa from right to left.The rotation of the print timing detection roller 9 generates a print timing signal (pulse) according to the rotation speed. ) is input to an external control device, the control device synchronously outputs a required code signal, which is input to the thermal head 4.

It is clear from the above that as the pen shaft 1 is moved, the desired characters are thermally transferred onto the paper surface 17 at constant intervals regardless of the speed of the pen shaft 1. The thermal printing tool of the present invention is novel as a thermal printing tool because it can perform thermal printing by operating it like a normal pen, and the thermal printing ribbon can be easily replaced.
