Abstract

PURPOSE:To enable the easy recording of characters or the like at any positions on a recording paper or the like by constructing a thermal recording device such that a thermal recording head is disposed at a distal end of a pencil-like shaft unit. CONSTITUTION:Character information on different characters is read out of a memory 52 each time an operation signal of a switch 6 is supplied, and a display control signal for displaying a character related to the information on the basis of the information so read out is then supplied to a display driving circuit 54, thereby displaying a character currently so selected on a display 3. In a case where a character to be recorded on the display 3, a stem 1 is set such that a recording head 2 is located on a desired position on a recording paper 8. Thereafter, when a recording button switch 7 is pressed down, a recording control signal based on the information read out of the memory 52 is kept supplying from a microprocessor 51 to the recording driving circuit 53 for a predetermined period of time t. This causes a thermal resistive unit of the recording head 2 to be selectively driven, thereby recording the character appearing on the display 3 on the recording paper 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Light] (Industrial Application Field) The present invention relates to a thermal recording device for recording at an arbitrary position on a recording material.

(Prior Art) Thermosensitive recording devices have been widely used as recording means for word processors and the like.

(Problem to be Solved by the Invention) The conventional thermal recording device described above is capable of recording at a position on the recording paper specified by the keyboard, but once the recording is finished, characters etc. can be placed at the desired position on the recording paper. It is very difficult to record. Further, there is also the inconvenience that it is impossible to record on uneven areas or on a recording material having a J method that does not conform to a predetermined format.

SUMMARY OF THE INVENTION In view of this situation, it is an object of the present invention to provide a heat-sensitive recording device that can easily record characters, etc. at any arbitrary position on a recording paper or the like.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a structure in which a thermosensitive recording head is disposed at the tip of a pencil-shaped shaft.

(Function) According to the above configuration, by positioning the recording head at a desired recording location, recording is performed at the desired recording location.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of a thermal recording device according to the present invention.

This embodiment includes a pencil-shaped shaft 1, a recording head 2 for heat-sensitive two sickles disposed at the tip of the shaft 1, and a shaft 1.
A display 3 consisting of an LCD etc. arranged at the rear end, a control section 5 housed in the shaft 1 as shown by the dotted line, and a shaft 1
It has a configuration including a character selection push button switch 6 and a recording start push button switch 7 with push button portions exposed to the outside.

The recording head 2 is arranged to be inclined by an angle θ with respect to a plane perpendicular to the axis of the shaft 1. Therefore, when the shaft 1 is tilted by the angle shown in the figure, the recording surface of the head 2 records. It will be in contact with paper 8.

The control unit 5 controls the switch 6 as illustrated in FIG.
．． A microprocessor 51 such as a CPU to which the output signal of 7 is applied, and a memory 5 in which a plurality of character information is stored in advance.
2, a recording drive circuit 53 that drives the heating resistor of the recording head 2, and a display drive circuit 54 that drives the display 3.

Note that a battery (not shown) for supplying power to the recording head 2, display 3, and flu control unit 5 is housed in a suitable place inside the shaft 1 or in a battery case separate from the shaft 1. .

Next, the operation of this embodiment will be explained.

When the character selection push button switch 6 is pressed after turning on a power switch (not shown), the processor 5 executes the following process.

That is, character information regarding a different character is read out from the memory 52 each time the operation signal of the switch 6 is input. Then, based on the read information, a display control signal for displaying a character related to the information is input to the display drive circuit 54, whereby the currently selected character is displayed on the display 3.

When one character to be recorded is displayed on the display 3, the shaft 1 is moved so that the recording head 2 is positioned at a desired location on the recording paper 8.
is set.

Thereafter, when the recording push button switch 7 is pressed, a recording control signal based on the character information read from the memory 52 is outputted from the microprocessor 51 to the recording drive circuit 53 for a predetermined time t. As a result, the photothermal resistor of the recording head 2 is selectively driven, whereby the characters displayed on the display 3 are recorded on the recording paper 8.

The time t is the required recording time by the thermal recording head 2, and is set by a timer built into the processor 51.

Thereafter, by performing similar operations, desired characters can be recorded at desired positions of the recording paper name.

FIG. 3 shows another embodiment of the invention.

This embodiment has a shaft body 9 consisting of a body portion 91 and a movable tip portion 92. A W41j body 10 is fitted into the body 91, and a push button switch 11 is fixedly disposed opposite the sliding body 10. A spring 12 is interposed between the sliding body 10 and the switch 11, and the repulsive force of this spring keeps the sliding body 9 in constant contact with the inner surface of the tip of the body 91.

The movable tip 92 is moved through the bottle 13 to l! ! ! It is pivoted on the U-body 10, so that in this embodiment the angle θ shown in FIG. 1 can be varied within a certain range.

Furthermore, in this embodiment, by pressing the trunk 91,
The sliding body 10 retreats against the spring 12, and the switch 11 is actuated by its rear surface. Therefore, if this switch 11 is used in place of the recording start push button switch 7 shown in FIG. 2, the printing operation can be further simplified.

By the way, if the internal volume of the shaft body 1 (or 9) is small, it may not be possible to accommodate electronic components such as a battery or a RAM pack in this shaft body.

In such a case, as shown in FIG. 4, a component storage case 14 may be connected to the shaft body 1, and the electronic component may be stored in this case. This case 13 is desirably formed into the shape shown in the figure, for example, so that it can be used as a grip during recording.

When using the case 13 as described above, it is also possible to attach a small keyboard at a suitable location, thereby speeding up character selection and increasing the number of selected characters.

In addition, without integrally connecting the storage case 13 and the shaft body 1,
Of course, it is also possible to connect the two with a cable of an appropriate length.

In the case of each of the above embodiments, it is necessary to make the recording material such as the recording paper 8 heat sensitive, but if carbon paper or ribbon for thermal transfer is used together, the recording material without heat sensitivity can be used. can also be applied. Note that it is also possible to attach a ribbon for transfer at a suitable position at the tip of the shaft.

〔Effect of the invention〕

According to the present invention, characters, symbols, etc. can be recorded at any position on a recording material in the same way as pressing a seal. Furthermore, it is also possible to print on uneven portions of the recording material and to print on irregularly shaped recording materials.
