Abstract

PURPOSE:To enhance efficiency of cooling a printing head, by a blowing means for the head. CONSTITUTION:In a printing operation, a timing belt 7 is driven by a carriage motor 6 to move a carrier 5 in the direction of an arrow B, and printing is conducted by a printing head 1. As the carrier 5 is thus moved by the timing belt 7, a gear 4c converts the rectilinear motion into a rotational motion, which is transmitted by an intermediate gear 4b to a bevel gear 4a, and the gear 4a rotates a cooling fan 3, whereby air is blown to the printing head 1. Heat generating elements 2 of the head 1 are forcibly cooled by the air blown by the fan 3, and the heat generated by the elements 2 at the time of printing is moderated.

Description

DETAILED DESCRIPTION OF THE INVENTION Hiroshi Kijiro relates to a cooling mechanism, and particularly to a cooling mechanism for a thermal transfer serial printer that prints by welding ink to printing paper using a print head.

Conventionally, in thermal transfer printers, methods for cooling the print head include attaching a heat sink to the print head to naturally cool the print head, and improving ventilation around the print head to naturally cool the print head. I used to go there.

Conventional methods for cooling the print head of thermal transfer printers include attaching a heat sink to the print head to naturally cool the print head, or improving ventilation around the print head to naturally cool the print head. The disadvantage is that the cooling efficiency is poor and the print head cannot be sufficiently cooled.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional system, and aims to provide a cooling mechanism that can improve the cooling efficiency of the print head and sufficiently cool the print head. .

Composition of the Invention The cooling mechanism according to the present invention is a cooling mechanism for a thermal transfer serial printer that prints by welding ink to printing paper using a print head, and is provided with an air blower for blowing air to the print head, and the cooling mechanism is a cooling mechanism for a thermal transfer serial printer that prints by welding ink to printing paper using a print head. The printing head is characterized in that forced cooling of the print head is performed.

1 凰3 Next, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a plan view showing one embodiment of the present invention, and Fig. 2 is a plan view showing an embodiment of the present invention.
It is an AA sectional view of the figure. In these figures, one embodiment of the present invention includes a print head 1 having a heating element 2, a cooling fan 3, a cooling fan drive system 4, a print head 1, a cooling fan 3, and a cooling fan drive system 4. The carrier 5 is composed of a support rear 5 for holding the carrier 5, a carriage motor 6 for moving the carrier 5, and a timing belt 7.

The cooling fan drive system 4 converts linear motion by the carriage motor 6 and timing belt 7 into rotational motion by a gear 4C (see the arrow in the figure, the same applies hereinafter), and transmits this rotational motion to the bevel gear 4a via an intermediate gear 4b. By doing so, the cooling fan 3 attached to the heavy vehicle 1i4a is rotated.

During a printing operation, the carrier 5 is driven by the carriage motor 6 and moved by the timing belt 7 in the direction of arrow B, and the print head 1 performs printing.

At this time, as the carrier 5 is moved in the direction of arrow B by the timing belt 7, this linear movement is converted into a rotational movement by the gear 40, and this rotational movement is transmitted to the bevel gear /la through the intermediate gear 4b. The rotational movement of the bevel gear 4a causes the cooling fan 3 to rotate, and the cooling fan 3 blows air to the print head 1.

The heating element 2 of the print head 1 is forcibly cooled by air blowing from the cooling fan 3, and the heat generated by the heating element 2 during printing operation is reduced.

In this way, by blowing air to the print head 1 using the cooling fan 3 and the cooling fan drive system 4 to forcibly cool the print head 1, the cooling efficiency for the print head 1 can be improved and the cooling fan drive system 4 can be used to cool the print head 1 sufficiently. The print head 1 can be cooled.

In addition, by making the cooling fan 3 rotate as the carrier 5 moves, the print head 1 can be moved at a low cost.
can be cooled.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the print head is forcedly cooled by the air blowing means provided for blowing air to the print head, thereby improving the cooling efficiency of the print head. This has the effect that the print head can be sufficiently cooled.
