Abstract

PURPOSE:To eliminate the need for a driving motor to be used exclusively for rotating a cooling fan, by a system wherein the rotation of a motor for transversely feeding a carrier supporting a printing head thereon is mechanically transmitted to rotatable vanes to rotate the vanes. CONSTITUTION:A bevel gear 8 is fitted to a rotary shaft of a motor 3, and rotary vanes 6 for cooling are fitted to a bevel gear 7 engaged with the gear 8. Therefore, the rotation of the motor 3 is transmitted to the vanes 6 through the bevel gears 7, 8 to rotate the vanes 6. When the moving direction of a printing head 1 is reversed, the rotating direction of the vanes 6 is also reversed to thereby introduce cool air from the exterior into the printer or discharge warm air from the printer to the exterior, whereby a controlling part 9 is forcibly cooled.

Description

[Detailed description of the invention] Technical field The present invention relates to a cooling method for a printer.

BACKGROUND ART Conventionally, forced cooling fJi using a cooling fan has been a common method for cooling printers, and a motor integrated into the cooling fan is used as a rotational drive source for this cooling fan. . Such cooling fans with motors are expensive, and are a factor in increasing the cost of printer devices.

OBJECTS OF THE INVENTION The present invention uses such an expensive cooling fan.The printer cooling method according to the present invention mechanically transmits the rotation of a motor for traversing a carrier carrying a print head to rotatable blades. It is characterized by the fact that it rotates to achieve cooling.

Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a schematic diagram schematically showing the configuration of an embodiment of the present invention, in which 1 is a print head, 2 and 4 are pulleys, 5 is a wire, 6 is a rotary blade (fan), and 7 and 8 are heavy-duty vehicles. Gears 9 indicate control units that require cold fJI.

The print head 1 is supported by a carrier (not shown), and is driven to move in the left-right direction in the figure by the rotation of the motor 93 together with this carrier. In this case, the print head 1 is moved in the lateral direction by a wire 5 attached between the pulleys 2 and 4.

A double gear 8 is attached to the rotating shaft of the motor 3.
A rotating blade 6 for cooling is attached to both heavy gears 7 meshing with this gear 8. Therefore, the rotation of the motor 3 is transmitted to the blade 6 via the two gears 7 and 8, causing the blade 6 to rotate. Each time the direction of movement of the print head 1 changes, the direction of rotation of the blades 6 also changes, drawing in cold air from outside into the printer device, and exhausting warm air inside the device to the outside of the device, resulting in forced cooling. This makes it possible to cool the control section 9, which requires the following steps.

11 As stated above, according to the present invention, a dedicated drive motor is not required to rotate the cooling fan, so only an inexpensive rotary blade can be used, thereby reducing the price of the printer device. This has the effect of making it possible to press down.
