There is a dot impact printer that performs recording and writing on this sheet.

The recording head 1 of such a printer includes:
As shown in FIG. 13, a driving unit 2 for operating a recording wire
A radiator 3 having a plurality of fins is provided around the drive unit 2 in order to cool the radiator 3.

In order to further improve the cooling performance of the radiator 3, there is a recording head 1 in which a cooling fan 4 is installed on the back of the radiator 3 (first prior art). In some cases, the cooling fan 4 is not installed on the recording head 1 but is installed on a peripheral portion of the recording head 1 (for example, a carriage on which the recording head 1 is mounted) (second prior art).

[0005]

However, the above-described first method
In the related art, since the cooling fan 4 is installed on the back surface of the recording head 1, the length N in the front-rear direction N of the recording head 1 perpendicular to the traveling direction of the recording head 1 increases, and the recording head 1 becomes large. It will be.

In the first prior art, the length of the recording head 1 in the front-rear direction N is shorter than the length in the running direction, and therefore, the length of the radiator 3 in the front-rear direction is also shorter.
For this reason, the cooling air generated by the cooling fan 4
Therefore, the cooling efficiency of the radiator 3 in the recording head 1 cannot be improved.

In the above-mentioned second prior art, the space around the recording head 1 is limited. Therefore, it is difficult to design a cooling fan for generating a desired air volume in this limited space. is there.

Further, according to the second prior art, when the cooling fan 4 is installed below the back side 5 of the radiator 3,
Even when the cooling fan 4 is installed below the side portion 6 of the radiator 3, since the cooling fan 4 and the radiator 3 are separated,
The loss of the amount of cooling air generated by the cooling fan 4 is large, and the drive unit 2 of the recording head 1 cannot be cooled appropriately.

In view of the above circumstances, an object of the present invention is to provide a recording head of a recording apparatus capable of improving the cooling efficiency of a radiator while ensuring miniaturization. It is another object of the present invention to provide a recording apparatus capable of improving the cooling efficiency of a radiator in the recording head while ensuring the miniaturization of the recording head.

[0010]

According to a first aspect of the present invention, there is provided a recording head of a recording apparatus having a radiator provided with fins extending along a running direction of the recording head and a plurality of recording wires. The radiator is characterized in that one or a plurality of cooling fans are provided on at least one of a side surface portion perpendicular to the traveling direction and a top surface portion parallel to the traveling direction.

According to a second aspect of the present invention, in the first aspect of the present invention, the cooling fan is embedded in a radiator.

According to a third aspect of the present invention, in the first or second aspect, a wind guide plate for guiding cooling air to the inside of the radiator is provided outside the radiator. It is a feature.

According to a fourth aspect of the present invention, a recording head having a large number of recording wires is mounted on a carriage that can travel along a platen, and the recording wires protrude toward the platen. In a recording apparatus in which an image is recorded on a sheet conveyed between the platen and the recording head, the recording head includes fins extending along a traveling direction of the recording head traveling with the carriage. A radiator, wherein the radiator is provided with at least one cooling fan on at least one of a side surface portion perpendicular to the traveling direction and a top surface portion parallel to the traveling direction. Things.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the cooling fan is embedded in a radiator.

According to a sixth aspect of the present invention, in the fourth or fifth aspect, a wind guide plate for guiding cooling air to the inside of the radiator is provided outside the radiator. It is a feature.

The invention according to claim 1 or 4 has the following operation.

In the radiator of the recording head, one or a plurality of cooling fans are provided on at least one of a side surface portion perpendicular to the traveling direction of the recording head and a top surface portion parallel to the traveling direction. Since the length of the radiator along the traveling direction of the recording head is longer than the length in the front-rear direction perpendicular to the traveling direction, the area where the cooling air generated by the cooling fan contacts the radiator can be increased. Therefore, the cooling efficiency of the radiator in the recording head can be improved.

Further, since the cooling fan is provided on at least one of the side surface and the top surface of the radiator and is not provided on the rear surface, the length of the recording head in the front-rear direction orthogonal to the traveling direction of the recording head is reduced. Therefore, the size of the recording head can be reduced without increasing the size.

The invention according to claim 2 or 5 has the following operation.

Since the cooling fan is embedded in the radiator, the cooling fan for generating the desired air volume can be installed in a limited space without increasing the size of the recording head.

Further, since the cooling fan is embedded in the radiator, most of the cooling air generated by the cooling fan can be guided to the radiator, so that the loss of the cooling air amount can be reduced, and the heat radiation in the recording head can be reduced. The cooling efficiency of the vessel can be improved.

The invention according to claim 3 or 6 has the following operation.

Since the air guide plate for guiding the cooling air to the inside of the radiator is disposed outside the heat radiator,
The cooling efficiency of the radiator by the cooling air generated by the cooling fan can be further improved.
