Abstract

PURPOSE:To monitor the state of printing easily by forming the front of a casing in an inclined plane, forming a printing-state monitor window to the inclined plane and providing the inside of the casing with a means forwarding printing paper to an upper section from a lower section along the inclined plane in the casing. CONSTITUTION:Printing paper 3 inserted from the lower section of the front of a casing 1 is forwarded by a tractor 9 to an oblique upper section along an inclined plane 1a in the casing 1, passes between a printing head 2 and a flat platen 8, and drawn out to the outside from the horizontal upper surface side of the casing 1. A window 7 is formed to the inclined plane 1a, and the printing head 2 is fitted toward an oblique lower section in the lower section of the upper edge section of the window 7. On the other hand, a motor in said tractor and an electric circuit 6 driving the printing head 2 are received in a lower space partitioned by printing paper 3 in the casing 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to printers, and more particularly to a blink that improves the arrangement of printer components within a casing.

A conventional printer of this type is shown in FIG. Fig. 1 is a side view showing the positional relationship of the main components of the printer.
The right side in the figure) has an elongated rectangular cross section with a constant depth toward the front side, and the tmK print head 2. A roll platen 4 degrees that receives the print head 2 and winds the print paper 3. A motor 5 for driving the print head 2.
An electric circuit 6 for driving this motor 5 is housed.

The printing paper 3 is inserted into the casing 1 through the window 7 provided on the substantially horizontal upper surface of the casing 1, passes between the motor 5 and the roll platen 40, is wound around the roll platen 4, and is placed between the print head 2 and the print head 2. It passes through the window 7 and is pulled out of the casing 1.

However, in the conventional printer described above, each of the above-mentioned components including the print head 2 are arranged side by side from the front of the casing 1 to the back of the casing 1, so when using it on a narrow desk etc. It occupies a large area and is difficult to handle. The print paper 3 on the roll platen 4 printed by the print head 2 looks like K when viewed through the window 7 provided on the upper surface of the casing 1 which is approximately horizontal. It is very difficult to see from the horizontal direction.

The present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a printer that occupies a small area even on a narrow table like a desk, and allows the user to easily monitor the printing status. In a printer that houses a print head, a motor and drive circuit for driving the print head, a platen that receives the print head via printing paper, etc. in the casing, the front surface of the casing is formed as an inclined surface, and this slope A window for monitoring the printing state is provided on the surface, a paper feeding means for feeding the printing paper from below to above along the inclined surface is provided in the casing, and a print head is provided near the upper edge of the window, A platen for receiving printing paper to be printed is arranged at a position facing the print head, and of the space in the casing divided by the printing paper, the paper feeding means, the paper feeding means and the platen in the space on the side where the platen is provided. The electrical circuit is housed in the peripheral portion of the device.

Embodiments of the present invention will be described below based on the drawings.

FIG. 2 is a side view showing the positional relationship of the main components in the printer according to the embodiment of the present invention.

The casing 1 has a roughly pentagonal cross section, like a rectangle with a part cut out, and has a print head 2 inside, similar to the conventional printer. Platen8. A tractor 9 and an electric circuit 6 are housed, and the platen 8 is a fixed flat platen that has a flat print receiving surface and does not rotate, and the printing paper 3 is fed by the tractor 9 that has a built-in motor. It has become.

The inclined surface 1aK provided on the front surface of the casing l is the window 7.
A print head 2 is attached below the upper edge of the window 7 so as to face obliquely downward, and the flat platen 8 is fixed opposite to the print head 2. The tractor 9 is disposed in front of the flat platen 80, and the printing paper 3 inserted from the lower front side of the casing 1 is sent diagonally upward along the inclined surface 1aK of the casing 1 by the tractor 9, and is sent to the print head 2. and the 7-rat platen 8, and is pulled out from the horizontal upper surface side of the casing 1.

On the other hand, an electric circuit 6 for driving the motor and print head 2 in the tractor is housed in a lower space within the casing 1 defined by the print paper 3.

That is, as shown in FIG. 2, the tractor 9. Flat platen8. The mechanical unit (A) formed by the print head 2, etc. has an approximately rectangular parallelepiped shape as a whole, and when it is arranged along the inclined surface 1aK, it becomes K, so the casing 1 has an approximately pentagonal cross section.
In fkjK, a space having a substantially triangular cross section remains behind. Therefore, the electric circuit 6 is formed and housed here as a unit B. Since the unit (B) of the electric circuit 6 is relatively easy to change its overall shape in various ways, it is easy to fit it into the space having the substantially triangular cross section. It can be made smaller.

When using this printer on a desk, please use the inclined surface 1.
The tip of the print head 2 and the surface of the print paper 30 to be printed are monitored through the window 7 provided aK. The position of the user's eyes may be on one side diagonally above the casing 1 or in a substantially horizontal direction.

Incidentally, the angle and size of the inclined surface 1a of the casing 1 depend on the operating conditions of the printer, the position of the print head 2, and the casing 1.
It can be selected appropriately by considering the horizontal dimension m etc. of
Further, although a flat platen is used in the above embodiment, a conventional roll platen may also be used.

Since the present invention is as described above, the overall depth of the printer can be made smaller than that of conventional printers, and printing conditions can be monitored from a wide field of view. Therefore, for small printers that are placed on desks etc.
It occupies only a small space and is extremely easy to use.
