Abstract

PURPOSE:To prevent the damage of the linearity in recording caused by the addition of external force to paper during recording, by retracting one of paper discharge rollers by a retraction means during a time when the paper while recording passes through a recording part. CONSTITUTION:The paper 9 fed out from a paper cassette 8 is guided between a thermal head 2 and a back-up roller 3 by a guide 11 and image information is recorded on the paper 9 by the thermal head 2 while the recorded paper 9 is guided by a guide 12 to reach a paper discharge roller 13. The discharge roller 13 consists of a pair of rollers mutually contacted under pressure and, one of them, for example, the upper side on is made freely retractable upwardly by a retraction means. For example, the retraction means is a solenoid and retracts one of the paper discharge roller 13 upwardly during a time when information is recorded on the paper 9 by the thermal head 2 and, by this mechanism, the recording of information can be performed without applying external force to the paper 9 during recording.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a transfer type thermal recording device with improved recording linearity.

2. Description of the Related Art As a conventional transfer-type thermal recording apparatus for recording information on paper using a thermal head and a heat-fusible or heat-sublimable ink donor film (IDF), the one shown in FIG. 2 is known. The recording apparatus includes a thermal head α and an ink donor film C fed out from a supply roller b.

After information is recorded on the paper e fed out from the paper cassette d using the thermal head α and the ink donor film cf, the paper e is ejected to the ejection tray y by the ejection roller f. There is.

Problems to be Solved by the Invention However, in the above-mentioned recording apparatus, there was a problem in that the paper feeding pattern in the recording section fluctuated due to variations in the conveyance force of the paper ejection roller f, resulting in deterioration of recording linearity in the recording section. .

This invention was made for the purpose of improving the above-mentioned problems.

Means and Effects for Solving Problems: A retracting means is provided for retracting one of the paper ejection rollers that ejects the paper on which information has been recorded from the thermal head and the ink donor film to the paper ejection tray until the recording is completed. This is a transfer type thermal recording device that prevents external force from being applied to the paper during recording.

Embodiment One embodiment of the present invention will be described in detail with reference to FIG. 1. In the figure, reference numeral 1 denotes a main body, inside which a thermal head 2 and a back roller 3 are installed facing each other. 4 is a supply roller, and the ink donor film 5 sent out from this supply roller 4 is guided between the thermal head 2 and the back roller 3 on one side of the idler shaft 6 installed on both sides of the thermal head 2. Yet another idler @
6 and then wound onto a winding flora 7.

On the other hand, g is a paper cassette containing paper 9.

The sheets 9 stacked in the paper cassette 8 are fed out one by one from the top by a feed roller. The fed paper 9 is guided by the guide 1 between the thermal hand 2 and the back roller 3, and image information etc. are recorded on the paper 9 by the thermal head 2, and the paper 9 recorded with 15i88 is guided by the guide (2) and reaches the paper ejection roller 13. The paper discharge roller 13 is made of a pair of rollers that are in pressure contact with each other, and one of the rollers (for example, the upper side) can be retracted upward by a retracting means (not shown). While information is being recorded on the paper 9, one of the paper ejection rollers 13 is retracted upward, so that information can be recorded without applying external force to the paper 9 during recording.Also, the recording is completed. Then.

In response to the end signal, the evacuation means presses the retracted paper ejection rollers 13 against each other, so that the paper 9 is thereafter transported by the ejection rollers 13 and ejected to the paper ejection tray 14.

Effects of the Invention As described in detail above, in this invention, one of the paper ejection rollers is retracted by the evacuation means until the paper 9 being recorded passes through the recording section. No external force is applied. This makes it possible to reliably prevent recording linearity from being impaired.

Claims (1)

[Claims] In a device that records information on paper 9 fed from a paper cassette 8 using a thermal head 2 and an ink donor film 5, the paper 9 on which information has been recorded by the thermal head 2 is discharged to a paper output tray 14. A transfer type thermal recording apparatus is provided with a retracting means for retracting one of the paper ejection rollers 13 until recording is completed.
