2. Description of the Related Art A conventional printer first prints an edge of a printing paper or an alternative to the printing before starting printing.
For example, a predetermined reference position of the transport roller is detected. Next, the head is moved to the surface of the printing paper to start printing.

[0003]

As described above, in order to start printing after detecting the edge of the printing paper, there is a problem that a wasteful area is required from the paper edge to the printing start position.

FIG. 1 is a diagram showing an example of a configuration of an embodiment of a thermal printer to which a printing apparatus according to the present invention is applied. Print head (hereinafter abbreviated as head as appropriate)
Reference numeral 1 denotes a structure which can be moved up and down by a driving device (not shown). The conveyance belt 3 and the printing paper 4 are sandwiched between a rotatable platen 2 to generate printing pressure. The transport roller 5 is connected to a drive motor (not shown) and serves as a mechanism for driving the transport belt 3. Conveyor belt 3
Transports the printing paper 4, and the head 1 performs printing on the printing paper 4.

FIG. 2 shows the transport belt 3 and the printing paper 4 of FIG.
FIG. 3 is a diagram showing a detailed configuration of the embodiment. As shown in the drawing, the printing paper 4 has a configuration in which a color coating 6 is applied to the surface of a mount 7. The surface of the conveyor belt 3 is similarly provided with a color coding 11. Further, the transport belt 3 has a structure in which a groove 12 is cut in an area of the vertical and horizontal size of the printing paper 4 by the thickness of the printing paper 4.
Therefore, the color coating 11 of the transport belt 3 and the color coating 6 of the printing paper 4 have substantially the same height.

Next, the operation will be described. First,
When the printing paper 4 comes into contact with the transport belt 3, the drive roller 5 rotates and the transport belt 3 starts to move. Then, the printing paper 4 is pulled by the transport belt 3 by the friction between the transport belt 3 and the printing paper 4 and is transported toward the head 1. At this time, the printing paper 4 fits into the groove 12 cut by the transport belt 3.

The printing paper 4 is conveyed without displacement due to friction between the bottom of the groove 12 cut by the conveyance belt 3 and the mount 7 of the printing paper 4.

Before the transported printing paper 4 reaches below the head 1, the head 1 first goes down and the transport belt 3 is sandwiched between the printing paper 4 and the platen 2. In the case of a normal printer, at this time, the coefficient of friction between the head 1 and the transport belt 3 is too large, which may damage the head 1 or cause the transport roller 5 to lose synchronism. However, in the case of the above embodiment, since the transport belt 3 is provided with the color coating 11, it is possible to avoid an increase in the coefficient of friction between the head 1 and the transport belt 3. Therefore, damage to the head 1 and loss of synchronism of the transport roller 5 can be suppressed.

Next, the applied energy is applied to the head 1, and the temperature of the head 1 becomes a printable temperature. And
When the transport belt 3 moves as it is, the head 1 reaches the end of the groove 12 cut by the transport belt 3.

Since the printing paper 4 is contained in the groove 12, the head 1 which has already reached a printable temperature is used.
Printing can be performed from the end of the printing paper 4.

In the case of the conventional printer, when the head 1 reaches the end of the printing paper 4, a step corresponding to the thickness of the printing paper 4 is formed by the color coating 11 of the transport belt 3 and the color coating 6 coated on the printing paper 4. To occur in between,
The printing paper 4 is caught by the head 1 and the conveyance failure /
A jam or the like may occur. However, in the case of the above-described embodiment, since the printing paper 4 is contained in the groove 12 cut by the transport belt 3, a step is formed between the color coating 11 on the surface of the transport belt 3 and the color coating 6 on the printing paper 4. Since it does not occur, it is possible to avoid occurrence of transport failure / jam and the like.

Printing proceeds as it is.
The head 1 moves relatively from the color coating 6 on the printing paper 4 to the color coating 11 on the conveyor belt 3. Also in this case, as in the case described above, no step is generated between the color coating 11 on the surface of the transport belt 3 and the color coating 6 on the printing paper 4, so that transport failure / jam can be avoided.

Here, the color coating 6 on the mount 7 and the color coating 11 on the conveyor belt 3 are the same, but they do not need to be particularly the same if they have the same coefficient of friction. Coloring coating 11 of conveyor belt 3
Does not need to be colored. Further, since heat is applied by the head 1 every time printing is performed, a material having high heat resistance is preferable.

As described above, the printing apparatus of the present invention transports the printing paper 4 by the transport belt 3 having the surface processed in the same manner as the printing paper 4 and having the groove 12 for inserting the printing paper. By applying the applied energy to the belt 3, printing can be performed on the entire surface of the printing paper 4.

Therefore, in a printer using thermosensitive paper, by performing printing in a range that is equal to or greater than the conventional color development range, the entire color surface of the printing paper can be colored. Thereby, printing can be performed on the entire surface of the printing paper.

In the above embodiment, the case where the present invention is applied to a thermal printer has been described.
The present invention can be applied to other printers.
