Abstract

PURPOSE:To reduce the height and the thickness and to improve the storage space efficiency by bending a guide member downward at the rear then arranging a rotary fulcrum at the intermediate section of the holding section of an ink sheet cassette to be contained therein and providing a means for retracting a recording head to the rear of the guide member. CONSTITUTION:Guide member 5 for an ink sheet cassette 4 is bent downward at the rear and the fulcrum 10a of a head holder 10 is positioned slightly in the rear of the inclining section 5b of the guide member 5. Furthermore, the head holder 10 is bent perpendicularly thereby the ink sheet cassette 4 retracts to the rear of the guide member 5 when it is mounted on the body. By such arrangement, height and thickness of a transfer recorder can be reduced. Furthermore, since the arm 4b of the ink sheet cassette 4 is rotatable around the fulcrum 4C, it can be folded and stored in a limited space.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a thermal transfer type or electric transfer type recording device that presses a recording head against a platen via an ink sheet and recording paper to perform transfer recording on recording paper. In particular, the present invention relates to a transfer recording device characterized by a mechanism for attaching an ink sheet cassette to a main body.

[Conventional technology]

In this type of transfer recording apparatus, an ink sheet cassette that holds a take-up roll around which an ink sheet is wound and a supply roll at both ends of the ink sheet cassette is removable from the apparatus main body.

Recently, a mechanism has been proposed in which the ink sheet cassette is mounted from the front of the main body of the apparatus in order to improve operability, as disclosed in, for example, Japanese Patent Application Laid-Open No. 62-187059.

[Problem to be solved by the invention]

Generally, when installing an ink sheet cassette into the apparatus main body, the recording head is retracted so as not to interfere with the installation, but in the above conventional technology, when inserting the ink sheet cassette into the apparatus, the recording head is moved into the insertion Because it is retracted to the upper side, the height of the device becomes high, which is a disadvantage in that it goes against the trend of making devices thinner.

The present invention is based on the premise that an ink sheet cassette is installed from the front of the apparatus main body, and an object of the present invention is to provide a transfer recording apparatus that can reduce the height and thickness of the apparatus main body. Another purpose is to increase space efficiency when storing ink sheet cassettes.

[Means to solve the problem]

For this purpose, the present invention provides an ink sheet cassette that has a take-up roll with an ink sheet wound around each roll shaft and a supply roll on both ends of a holding part, which can be installed from the front of the apparatus main body along a guide member. In addition, in a thermal transfer type or electric transfer type transfer recording device in which an ink sheet and a recording paper are pressed against each other by a recording head using a platen, and information from the recording head is printed on the recording paper via the ink sheet, a guide member is used. The back side is bent downward, and a rotation fulcrum is provided in the middle of the holding part of the ink sheet cassette housed in this guide member, and when the ink sheet cassette is installed, the recording head is moved to the back side of the guide member. It is characterized by providing a means for evacuating the area.

[Effect]

In the present invention, the ink sheet cassette is bent and loaded to the back side of the platen, and the recording head is retracted further to the back side at that time, so that the apparatus can be made thinner.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a transfer recording apparatus according to an embodiment of the present invention, FIG. 2 is a simplified explanatory diagram of an ink sheet cassette mounting mechanism, FIG. 3 is a perspective view of an ink sheet cassette, and FIG. 4 is an ink sheet cassette mounting mechanism. FIG. 3 is a simplified side view of the sheet cassette in a stored state.

In FIG. 1, reference numeral 1 denotes an ink sheet wound around a take-up roll 2 and a supply roll 3, respectively, and the take-up roll 2 and supply roll 3 are at both ends of arms 4a and 4b, which serve as holding parts for an ink sheet cassette 4. is rotatably supported. Arm 4a.

4b is rotatably connected at a fulcrum 40.

Reference numeral 5 denotes a guide member that guides the ink sheet cassette 4 inserted from the front side of the apparatus main body (in the direction of arrow a), and has a shape in which the rear side is bent downward. The ink sheet cassette 4 is arranged such that the fulcrum 4c is exactly located at the bending part of the guide member 5, and the arm 4a is attached to the horizontal part 5a on the front side in the direction of arrow a, and the arm 4a is attached to the downwardly inclined part 5b on the back side. 4b facing the guide member 5. 6 is a platen, 7 is a recording head, and the ink sheet 1 and the recording paper 8 are placed on top of each other and are moved to a pressing roller 9.
The recording head 7 is pressed by the platen 6 and the recording head 7. Reference numeral 10 denotes a hook-shaped head holder bent at right angles, which has a recording head 7 attached to its tip and rotates about a fulcrum 10a. There is. This head holder IO is rotated by a mechanism (not shown) so as not to obstruct when the ink sheet cassette 4 is guided by the guide member 5 and installed in the main body.

11 is a manual feed stand for the recording paper 8, 12 is a paper feed roller, 13
is a paper conveyance guide. The paper feed roller 12 is driven by a drive source (not shown), grips and conveys the recording paper 8 inserted from the manual feed table 11, and guides it to a recording section consisting of a platen 6 and a recording head 7. The recording paper 8 is further conveyed along a paper conveyance guide 13.

The fulcrum 10a of the head holder 10 is located slightly below the inclined portion 5b of the guide member 5, and the fulcrum 10a of the head holder 10
Since the shape of is bent at a right angle, the second
As shown in the figure, when the ink sheet cassette 4 is attached to the main body, the guide member 5 is retracted backward rather than above.

As shown in FIG. 3, the arm 4b of the ink sheet cassette 4 is rotatable in the direction of the arrow around the fulcrum (connecting pin) 4c, so when storing it, it can be folded as shown in FIG. Small storage space is required. In addition, 4d is a take-up roll storage part, and 4e is a supply roll storage part.

〔Effect of the invention〕

As described above, according to the present invention, since the recording head does not protrude upward when the recording head is retracted, the height of the apparatus main body can be kept low and the apparatus can be made thinner.
