Abstract

PURPOSE:To contrive smoothening the initial insertion of a recording paper, by a construction wherein a paper guide is moved in conjunction with an opening action of an openable cover when fitting a recording paper, thereby eliminating the gap between the guide and an ink sheet. CONSTITUTION:When the openable cover 15 is opened in fitting the recording paper, the paper guide 13 is lowered in conjunction with the turning action of the cover 15 to eliminate the gap between the ink sheet 5 and the guide 13, and a leading end part 12 of the paper is led to the contact point of a platen 9 and a guide roll 11 by utilizing the difference between the radius of the platen 9 and the radius of curvature of the guide 13. With the cover 15 closed after the leading end part 12 of the paper is passed through the contact point, the guide 13 is moved upward in conjunction with the closing action of the cover 15 to be separated from the ink sheet 5, thereby preventing the ink sheet 5 from being wrinkled, whereas the leading end part 12 of the paper is passed between a feeding roller 22 and a guide roller 23, and is fed to the position of a recording paper discharging port 21, whereby preparing for printing is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal transfer recording device using an ink sheet and a recording paper, and relates to an improvement of a paper guide installed in I# opposite to a platen.

[Conventional technology]

Fig. 5 shows a conventional thermal transfer recording device of this type. In Fig. 2, (1) is a housing, (2) is an I-hfc hinge mounted on the bottom plate of the housing, and (3) is this hinge. The free end of the thermal head is supported at one end by the spring (
41, it is elastically supported by one unit. (5) is an ink sheet; :! 11
The thermal head (3) is separated from the platen (9) in order to prevent the platen from being deformed in situations other than recording. j? I'm here.

In the IflIJ failure described above, when starting to use the device or loading recording paper in case of running out of recording paper, insert the recording paper (leading edge of 81 + 13) between the ink sheet (5) and the platen (9). When the tray (9) is rotated, the leading edge a3 of the recording paper passes between the platen (9) and the paper guide holder [-9] and is sandwiched between the guide row above it and the platen (9), It becomes sticky as it is being transported.

[The problem that the invention attempts to solve]

In the conventional thermal transfer recording device, when the recording paper (81 g) is initially inserted, the ink'/
- After passing between the ink sheet fFi1 and the platen (9), as shown by the broken line in Figure 2, the tip az is connected to the ink sheet (5).
There were times when I accidentally sent the paper between the paper guide and the paper guide.

The object of the present invention is to prevent the above-mentioned malfunction from occurring at the initial stage of loading recording paper.

[Means to solve problem skin]

In the thermal transfer recording device according to the present invention, a single paper guide is movably attached to the recording paper ejection side of the platen, and the paper guide is linked to the rotational movement of an opening/closing lid that is opened when recording paper is loaded.

[Effect]

In this invention, the paper guide descends in conjunction with the rotation of the opening/closing lid when the recording paper is loaded, thereby closing the gap between the paper guide and the ink sheet being wound up. .

〔Example〕

Figures 1 to 4 show an embodiment of the present invention, and the same parts as the conventional one in Figure 8g5 are indicated by the same numbers.
In Figure 2, 00 is a vertically movable paper guide according to the present invention, α is a bottle protruding from the side of the paper guide trolley, and a9 is an opening/closing lid that is opened when recording paper is loaded. It is rotatably supported by the housing +11 by a support shaft αe. αη is the bottle provided at the tip of the protruding arm of this opening/closing lid a9, α■ paper guide (13) and the opening/closing lid (+9
A link plate connected to the bin 07+ provided on the protruding arm of the alFi paper guide 0 shown in FIG. (2) is a recording paper discharge port provided on the opening/closing lid a9, (2) is a recording paper feed roller, and (9) is its guide roller.

In the above 11+1*, first of all, Figure 1 shows the initial state when the recording paper is loaded. When the opening/closing cover (19) is opened when loading the recording paper, the paper guide a1 descends in conjunction with its rotation. , ink sheet (5) and this paper guide 0
In addition to eliminating the gap between paper guide A3 and paper guide A3, the difference in the radius of curvature of paper guide A3 and the radius of paper guide A3 is utilized.

It acts to guide the leading edge (I2) of the recording paper to the contact point between the platen (9) and the guide roll 6υ.In this way, after the leading edge aX8 of the recording paper passes the above contact point, the opening/closing lid a9 is closed. It is something.

Figure 82 shows the state in which the opening/closing lid (US) is closed, and the paper guide also moves in conjunction with the rotational movement of the opening/closing lid a9 when it is closed.
By rising and separating from the ink sheet (5) as shown in Figure 1, the occurrence of wrinkles on the ink sheet (51) is prevented, while the leading edge of the recording paper (a) is separated from the ink sheet (5) by the feed roller (5).
and the guide roller (to).

The recording paper is sent to the recording paper ejection port 6M, and preparation for printing is completed.

3 and 4 show a link mechanism between the opening/closing lid a9 and the paper guide Q1, and by opening the opening/closing lid a, the bin aη provided on its protruding arm is centered around the support shaft OO.
rotates, and this is converted into vertical movement of the paper guide If) by the link plate.

In the above embodiment, the opening/closing lid 69 and the paper guide 03 are interlocked via the link plate aFj, but the opening/closing lid a9
It is also possible to directly move the paper guide (+3) up and down by opening and closing the paper guide.

〔Effect of the invention〕

As explained above, in the thermal transfer recording device of the present invention, the paper guide moves in conjunction with the opening/closing operation when the recording paper is loaded, and the gap between the ink sheet and the paper guide is made smaller. Therefore, there is an effect that the initial insertion of recording paper can be performed smoothly.

[Brief explanation of drawings]

Figures 1 to 4 show an embodiment of the present invention, with Figure 1 being a partial sectional view when the I/C opening/closing cover is opened for loading recording paper, and Figure 2 showing the opening/closing cover. 3 and 4 are partial sectional views and perspective views showing one embodiment of the link mechanism, and FIG. 95 is a partial sectional view showing a conventional thermal transfer recording device. In the figure (5
) is an ink sheet. +81 record paper, (9) is the platen, and (a) is the guide roll. (1, 1 is a paper guide, (+9 is an opening/closing lid.) In other figures, the same - symbols indicate the same parts.

Claims (1)

[Claims] A paper guide installed on the recording paper ejection side of the internal platen is linked to the rotating operation of the opening/closing lid that is opened when recording paper is loaded, so that when the leading edge of the recording paper is initially inserted, the paper guide and its A thermal transfer recording device characterized in that a gap between the ink sheet and the ink sheet wound up at the bottom is eliminated, and the leading edge of the recording paper is guided along the paper guide toward a discharge side guide roll above the paper guide.
