BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side holder used for transportation and storage of a transfer ink film roll used in a transfer recording apparatus.

[0002]

2. Description of the Related Art In recent years, various recording apparatuses have been developed and used, and transfer recording apparatuses are also widely used. Transfer type recording apparatuses include a serial type printer in which a recording head scans in a direction perpendicular to a traveling direction of a recording sheet for recording, and a line type printer using a recording head corresponding to the entire width of the recording sheet. . Line type printers usually use a transfer ink film having a width substantially equal to the width of the recording paper.

In a line type printer, the transfer ink film is usually supplied in the form of a roll, and in order to mount the ink film roll on the printer, an operator sets the transfer ink film roll at a predetermined position of the printer, and then the ink film. The leading end of the ink film is manually pulled out, passed through a predetermined path, and then the leading end of the ink film is wound around a winding core. However, this work is not only troublesome, but it is difficult to properly wind the ink film having a wide width on the winding core on the winding side so that wrinkles do not occur and meandering does not occur.

Therefore, as a solution to this problem,
The tip of the ink film of the ink film roll is wound around the winding-side winding core in advance, and the supply-side winding core and the winding-side winding core are kept at a constant interval by a press plate provided with a protrusion to be inserted into each winding core. The ink film structure has
No. 0-9784.

[0005]

However, as shown in the above-mentioned Japanese Patent Laid-Open No. 60-9784, a pressing plate simply provided with protrusions is used to fix the cores on the supply side and the winding side. In some cases, it turned out to have the following problems. That is, the strength of the restraining plate is weak and the two cores may be twisted, and the core may rotate during transportation to loosen the ink film and cause wrinkles.

The present invention has been made in view of the above conventional problems, and includes a supply roll formed by winding a transfer ink film around a core, and a winding roll formed by winding the leading end of the ink film around the core. Provided is a side holder that can be integrated with each other by being attached to the end portion of the ink cartridge, and can prevent the supply roll and the take-up roll from twisting and prevent the ink film from loosening or wrinkling. The purpose is to

[0007]

A side holder of the present invention is a plate-shaped portion having a size that covers the end faces of a supply roll and a take-up roll, and is inserted into each core of the supply roll and the take-up roll. A spring-like protrusion formed on one surface of the plate-shaped portion so as to contact the skirt, and a skirt portion formed around the plate-shaped portion so as to protect the outer circumferences of the end portions of the supply roll and the winding roll. It is characterized by having.

[0008]

The side holder having the above structure is attached to the ends of the supply roll and the winding roll by inserting the spring-like protrusions into the ends of the cores of the supply roll and the winding roll.
Both can be integrated to facilitate transportation and storage. At this time, the spring-shaped protrusions contact the inner surfaces of the cores of the supply roll and the take-up roll by a spring action, so that the rotation of the core can be prevented and the wrinkles of the ink film can be prevented. Since the rigidity is imparted to the roller, the twist of the supply roll and the take-up roll can be prevented, and the skirt portion covers the outer circumference of the end of the supply roll and the take-up roll, so that the outer circumference of the end of the ink film can be protected. Therefore, by using the side holder having the above structure, the ink film can be well protected during transportation and storage of the supply roll and the take-up roll.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of a transfer ink film package (hereinafter referred to as a transfer ink film structure) using a side holder according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view thereof. In the figure, a transfer ink film structure generally designated by reference numeral 1 is a supply roll 4 formed by winding a transfer ink film 2 around a winding core 3, and a winding roll formed by winding the leading end of the ink film 2 around a winding core 5. The roll 6 and the roll 6 are lined up with a minute gap therebetween, side holders 7, 7 are attached to both ends of the roll 6 to fix the supply roll 4 and the winding roll 6, and a protective cover 8 is provided on the outer periphery of the supply roll 4 and the winding roll 6. Is provided.

Here, the side holder 7 is, as shown in an enlarged manner in FIGS. 3 and 4, a plate-like portion 9 having a size that covers the end faces of the supply roll 4 and the winding roll 6, the supply roll 4 and the winding roll. The spring-like projections 10 formed on one surface of the plate-like portion 9 so as to be inserted into the respective winding cores 3 and 5 of the take-up roll 6 and contact the inner surface thereof.
10 and the spring-like projections 10 and 10 are raised from the plate-like portion 9 at the roots of the spring-like projections 10 and 10 so as to come into contact with the end faces of the cores when they are inserted into the cores 3 and 5. The formed ridges 11 and 11, the supply roll 4 and the winding roll 6
It is provided with a skirt portion 12 formed around the plate-shaped portion 9 so as to protect the outer periphery of the end portion of, and can be manufactured at low cost by molding plastic, for example. The spring-like projection 10 is formed by providing a longitudinal groove 10A in a cylinder so that it can be easily elastically deformed, and has a tapered portion 10B at its tip. The maximum outer diameter of the protrusion 10 is selected to be slightly larger than the inner diameters of the winding cores 3 and 5. With this configuration, each winding core 3 of the supply roll 4 and the winding roll 6,
5, the protrusions 10 and 10 of the side holder 7 can be easily inserted, and in the inserted state, the protrusions 10 and 10 are strongly contacted with the inner surface of the core by their own elastic force and fixed to the cores 3 and 5. That is, in other words, the cores 3 and 5 are the side holders 7.
The cores are fixed to each other via the protrusions 10 and 10, so that the cores are kept at a constant interval and their rotation is prevented. For this reason, it is possible to prevent the winding cores 3 and 5 from rotating during transportation or the like to cause slack in the ink film 2 to cause wrinkles.

In the supply roll 4 and the winding roll 6,
Normally, the end surfaces of the winding cores 3 and 5 and the end surface of the ink film 2 wound around the same are the same surface, but the side holder 7

Therefore, it is possible to prevent the end surface of the ink film 2 from coming into contact with the plate-shaped portion 9 of the side holder 7 and causing damage during transportation or the like. Further, the skirt portion 12 is the plate-shaped portion 9
To the plate-shaped part 9 in the assembled state as shown in FIG.
This prevents bending of the supply roll 4 and the take-up roll 6 due to bending and protects the end portion of the ink film 2. The protective cover 8 may be any paper, film, etc., so that when the transfer ink film structure 1 is handled, it does not come into direct contact with the ink film 2, and when the side holders 7, 7 are removed, the protective cover 8 is wound around the supply roll 4. The take-up roll 6 is provided so as not to come apart.

Next, a method of using the transfer ink film structure 1 having the above structure will be described. After the transfer ink film structure 1 is assembled as shown in FIG. 1, the transfer ink film structure 1 is packaged in a suitable packaging material such as a bag or a box and then transported. FIG. 5 shows a schematic configuration of an example of a color recording apparatus using a transfer ink film. Reference numeral 15 is a paper feed cassette, 16 is a recording paper,
17 is a paper feed roller, 18 is a drum around which recording paper is wound, 1
Reference numeral 9 denotes a thermal head, and the supply roller 4 and the take-up roller 6 are attached to the thermal head 9 with the drum 18 and the thermal head 19 interposed therebetween. To set the transfer ink film structure 1 of FIG. 1 in this color recording device, the thermal head 19 is kept away from the drum 18, first the side holders 7, 7 are removed, and the supply roll 4 is set at a predetermined position. Then, it is only necessary to break the protective cover 8 and move the winding roll 6 to set it at a predetermined position. In this way, the ink film 2 can be properly set by simply setting the supply roll 4 and the winding roll 6 at predetermined positions. Since the recording operation is the same as the conventional one, the description is omitted.

As described above, in the side holder of the present invention, the plate-shaped portion has the spring-like protrusions inserted into the respective cores of the ink film supply roll and the winding roll, and the supply roll and the winding roll. Since it is provided with a skirt portion for protecting the outer periphery of the above, by fixing the skirt portion to both ends of the supply roll and the winding roll, the both can be integrated and transportation, storage, etc. can be facilitated. Moreover, at that time, since the spring-like projections contact the inner surfaces of the cores of the supply roll and the take-up roll by the spring action, it is possible to prevent the core from rotating and prevent wrinkles from being formed on the ink film. Since the skirt portion gives rigidity to the side holder, twisting between the supply roll and the take-up roll can be prevented, and the skirt portion covers the outer circumference of the end portions of the supply roll and the take-up roll, so that the end portion of the ink film can be prevented. It has an effect that the outer periphery can be protected and, finally, the ink film can be well protected during transportation and storage.

As shown in the embodiments of the drawings, if a ridge portion is provided at the base of the spring-like projection so as to contact the end face of each winding core, the end face of the ink film is substantially flush with the end face of the winding core. In the case where the plate-shaped portion is wound on the ink film, the raised portion comes into contact with the end surface of each winding core and holds the plate-shaped portion away from the end surface of the ink film. Can be prevented, which is preferable.
