Description

[Detailed description of the invention] The present invention is a printer unit, more specifically, a bottom cover is provided on the bottom of the unit body so that it can be opened and closed, and the printing paper supplied to the unit body passes through the inside of the unit body above the bottom cover. This invention relates to improvements in printer units that are transported.

An example of a conventional printer unit will be explained with reference to FIG. 5. In the figure, reference numeral 1' is a unit main body, and a rotating shaft 9' orthogonal to the label transport direction is provided on the bottom surface of the main body 1'. A bottom cover 5' that opens and closes at the center is provided, a thermal head 2' is provided on the unit main body 1', and a platen roller 6' and a dispenser 7' are provided on the bottom cover 5'.

When setting the labeled mount a etc. (printing paper) in the printer unit as mentioned above,
Since the labeled mount a had to be inserted between the rotating shaft 9' and the unit main body 1', it was difficult to set it even if the bottom cover 5' was opened.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to provide a printer unit in which it is extremely easy to set labeled mounts, etc. by making it possible to fully open the area where mounts with labels are set. be.

In the printer unit of the present invention, the bottom cover is located on one side of the printing paper transport path and is attached to be movable to open and close via a support shaft parallel to the transport direction, and a thermal The device is characterized in that the head is provided with a platen roller on the bottom cover.

An example of the implementation of the present invention will be described with reference to the drawings. In the drawing, 1 is a unit main body, and the main body 1 is a box shaped like a rectangular parallelepiped. A thermal head 2 is provided inside, and is biased by a spring 3. The thermal head 2 is always pressed evenly against the platen roller 6.

A fulcrum shaft 14 is provided parallel to the platen roller 6, and a support plate 15 is provided at the center of the head mounting plate 17 to which the thermal head 2 is attached, and is supported by the fulcrum shaft 14.

In order to provide flexibility in the left and right and up and down directions around the support plate 15 in FIG. Attach 16. The head mounting plate 17 is linked to the solenoid 4 and moves toward and away from the label or the like around the fulcrum shaft 14 as the solenoid 4 is turned on and off. The solenoid 4 is linked to move towards and away from the label etc. by turning on and off the solenoid 4.

The thermal head 2 prints on thermal paper of a conventionally well-known structure, and is used to energize appropriately to generate heat at predetermined locations, thereby printing the product name, price, etc. on the label.

A protruding piece 8 is provided protruding from the lower side of one side of the unit main body 1, a shaft portion 9 is integrally formed therein, and a bottom cover 5 is provided with a hole rotatably fitted into the shaft portion 9 so as to be openable and closable. .

The bottom cover 5 is provided with a platen roller 6 and a dispenser 7 of a conventionally well-known structure, and also provided with hanging shafts 10, 10 on the end side that can be opened and closed.

A hook 11 for hanging the above-mentioned hanging shaft 10, 10,
11 is rotatably provided on the side of the unit main body 1,
The hooks 11, 11 are connected by a connecting rod 12 and biased by a spring 13 so as to be latched.

Therefore, in the above embodiment, the hooks 11,1
Open the bottom cover 5 by removing the latch 1,
After setting the labeled mount (printing paper) a, the bottom cover 5 is closed.

According to the present invention, when setting printing paper such as a label or a mount with a label, by opening the bottom cover around the spindle, there are no obstacles such as the spindle on the transfer path of the printing paper. Since it is in the fully open state, printing paper can be loaded quickly and easily, and paper replacement work efficiency can be improved.

By doing so, we will reach our intended purpose.
