Description of the Related Art In recent years, personal computers and video recording devices have become widespread, and various printer devices capable of recording images of these devices have been proposed, and their demand has been increasing. Therefore, there is a demand for an inexpensive printer device capable of producing high-quality printed images, and there is also a strong demand for a small, lightweight, and portable printer device so that printing can be performed anytime and anywhere as a mobile printer device.

Generally, in a thermal transfer type printer, for example, three color dyes of yellow (Y), magenta (M), and cyan (C) are cyclically arranged in a predetermined order according to a video signal of an information source. In addition to circulating the applied color hard copy ink sheet, the Samar head is heated to sublimate the dye of the ink sheet to perform one-screen color printing on recording paper (thermal transfer recording paper). Further, this printer device controls the gradation by adjusting the amount of sublimed dye by controlling the time width of the current applied to the Samar head. After recording by such a method, the recorded recording paper is transported by the recording paper transport mechanism of the printer device. For example, the recording paper is sent out and accommodated in a paper discharge case to perform a recording step for one screen (one page). Will be completed.

On the other hand, the rear end portion of the recording paper 6 is transported to the recording paper transport path 43b while pushing down the tape member 42 attached to the guide plate 41c via the transport path 43a.
The first color printing is performed.

The position of the thermal head 20 at the time of printing is, for example, three positions (a position moved upward, a position moved downward as shown in the figure, and an intermediate position between them) in a standby state. The switching operation can be performed by the thermal head driving mechanism 21 so that the position becomes a (partial position), and the position is controlled by a control circuit 38 provided on the power board 22b according to the printing operation.

When the printing of the first color yellow (Y) on the recording paper 6 is completed, the control circuit 38 controls the drive of the thermal head drive mechanism 21 to separate the thermal head 20 from the platen roller 14. While moving to the partial position, the recording paper 6 is returned to the rear of the printer device 1 (to the right in the drawing) by the pinch roller 15 and the grip roller 40, and then the above operation is repeated thereafter to obtain the second color magenta ( M), the third color cyan (C), and the transparent overcoat (OP) are sequentially superimposed on each color on the recording paper 6 to perform color printing.

The recording paper 6 is held by the grip roller 40 and the pinch roller 15 until printing of each color is started.
The recording paper 6 is transported to the rear side (to the right in the drawing) of the printer apparatus 1 at this time. At this time, the leading end of the recording paper 6 is transferred to the recording paper transport path 44 between the U-shaped guide plates 13a and 13b. When the trailing end of the recording paper 6 is detected by a sensor (not shown), the rotation of the pinch roller 15 and the grip roller 40 controls the trailing end of the recording paper 6 based on the detection result. Is set at the print start position of the thermal head 20 and the platen roller 14.

When the printing of all the colors is completed in this way, the printed recording paper 6 is discharged to the outside of the apparatus through the recording paper conveyance path 43b by a paper feeding mechanism (not shown) for discharging, and the printing operation is completed. I do.

Therefore, according to the present embodiment, the power board 2 through which a large current flows, such as a battery section 34a and a control circuit for applying heat to the thermal head 20 to generate heat.
2b is arranged on the side close to the source and is centrally mounted on this one power board 22b, while the control board 22a for performing the recording paper feed control or the ink ribbon feed control that requires only a small current is provided on the power board 22b. It is arranged near a source, that is, an actuator (including the recording paper feeding mechanism 17 and the like) for performing the feeding operation, and is centrally mounted on one control board 22a.
Since the printer device is configured by mounting only the main substrate 22 formed in a character shape, it is possible to reduce the size and weight of the printer device, and to provide an optimal printer device for portable use. Becomes possible.

Even if the manufacturing process of the substrate is taken into consideration, since the substrate 22 is composed of the two substrates 22a and 22b, it is possible to carry out the manufacturing operation of the substrate in a shared manner. Can be easily performed, so that the manufacturing process can be simplified, which greatly contributes to cost reduction.

The present invention is not limited to the above-described embodiment, but includes the present invention even when the above-described embodiment is applied.

[0071]

As described above, according to the present invention, the mounting form and arrangement of the circuit board are improved so as to reduce the mounting area of the board. It is possible to reduce the weight and provide an optimal printer device for portable use. Further, since the structure of the substrate 22 used in the printer device 1 is structurally easy to manufacture, it is possible to simplify the manufacturing process and greatly reduce the manufacturing cost. I do.
