Description

Description Recording medium package Technical field

The present invention relates to a recording medium package for storing a recording medium such as paper. Background art

Conventionally, this type of recording medium package has been disclosed in Japanese Patent Application Laid-Open No. 63-180806.

There is a sheet feeding force set as a recording medium package as described in Japanese Patent No. 29. The paper feed cassette described in Japanese Patent Application Laid-Open No. 63-180629 includes a case portion of a wrapping paper wrapping member for wrapping the cut paper, and a cover of the cut paper wrapping member. And a pressure-sensitive adhesive tape which is a member for bonding the case portion and the lid portion, and cardboard used as holding means for cut paper. When using the paper cassette, the user using the paper cassette first removes the adhesive tape adhered to the paper cassette and puts the cut paper in the case of the packaging member. Remove the lid part of the cut paper packaging member from the case part of the cut paper packaging member. Then, when the user attaches the case portion of the cut paper packaging member containing the cut paper to the paper feeding section of the image recording device, a desired image is formed on the cut paper by the image recording device, and the desired image is formed. The cut paper on which the image was formed had been output from the image recording device.

However, in the conventional paper feed cassette, the adhesive tape has a complicated shape and has a complicated shape in order to adhere the case portion of the cut paper packaging member for wrapping the cut paper and the lid portion of the cut paper packaging member. Paper packaging case There is a problem that the work of removing the lid of the cut paper packaging member becomes complicated because the cover and the lid of the cut paper packaging member are bonded to each other.

In addition, the cover part of the cut paper wrapping member is removed from the case part of the cut paper wrapping member, and the case part of the cut paper wrapping member in which the cut paper 4 is stored is attached to the paper feeding portion of the image recording apparatus, and the cardboard is cut. If the separation pad is also used as a separation pad for separating cut paper, there is a problem that the feeding of cut paper by the image recording apparatus becomes unstable.

On the other hand, if thick paper is also used as a separation pad to stabilize the feeding of cut paper, the state of the part that comes into contact with the cut paper is an important factor.

For example, in an image recording apparatus that picks up cut sheets one by one with a pickup roller and records the cut sheets, the last cut sheet among the cut sheets stored in the sheet feed cassette depends on the state of the portion in contact with the cut sheet. There was a problem that the paper was picked up at the same time as the previous cut paper. This problem is not only a waste of paper, but also causes problems such as occurrence of jams and deterioration of recording quality.

This problem arises in large-scale image recording devices and desktop-size image recording devices that record on regular-size cut paper such as A4 size paper because there is a dimensional margin in the paper cassette or paper storage space. Although it is relatively easy to improve the coefficient of friction by attaching a material of sufficient thickness to the plate, such a material is not suitable for paper cassettes used in small, portable image recording devices. There is no dimensional space for mounting Since the number of sheets that can be stored in a sheet cassette used in such a small-sized image recording apparatus is limited, it is desirable that the last sheet be reliably supplied.

Furthermore, the paper cassette (hereinafter referred to as the recording medium package) itself Therefore, it is desirable that it be formed as simply as possible. Disclosure of the invention

The present invention has been made to solve such a problem, and a first object of the present invention is to provide a recording medium package capable of easily removing a cover.

The second object is that even when a recording medium package is mounted on an image recording apparatus and a part of the recording medium package is also used as a separation pad for separating the recording medium, the recording medium is not used by the image recording apparatus. An object of the present invention is to provide a recording medium package capable of stably feeding paper. -Further, a third object is to provide a recording medium package that can be easily formed.

In order to achieve this object, a recording medium package according to the present invention is for accommodating a plurality of recording media, and in particular, a holding unit for holding the plurality of recording media, and at least the holding unit And a storage part for storing the plurality of recording media so as to cover the storage medium, wherein the storage part is separable so that a part of the holding part is exposed, and a boundary where the storage part is separated is: It is characterized by being formed by linear perforations before separation.

In the recording medium package having such a configuration, the storage section is separable so that a part of the holding section is exposed, and a boundary where the storage section is separated is formed by a linear perforation before separation. The storage section can be easily separated. Also, when the recording medium package is mounted on a recording device, the separated portion does not directly support the recording medium, but is located above the recording medium, and the holding portion itself supporting the recording medium includes: Since there is no separated part, the hair on the edge after separation It is possible to ensure stable conveyance of the recording medium without being affected by feathering or the like.

In such a recording medium package, at least the holding portion is formed by cutting with a mold, and a surface corresponding to the sag portion among the ends of the holding portion formed by cutting with the mold is formed on the recording medium. They are arranged facing each other.

At least the holding portion is formed by cutting with a mold, and the end of the holding portion formed by cutting with the mold is arranged so that the surface corresponding to the sagging portion faces the recording medium. When the recording medium package is mounted on the recording device, the frictional force between the recording medium and the holding unit is stabilized, and more stable conveyance of the recording medium can be secured. That is, the cutting by the mold forms a sagging portion that is depressed near the cut surface and a projecting burr portion. Force The sagging portion faces the recording medium and does not protrude from the recording medium. It does not hinder.

Further, it is preferable that the holding section and the storage section are formed of one sheet of paper. Since the holding section and the storage section are formed of one sheet of paper, the recording medium package can be formed more easily. Further, it is preferable that the storage section covers one or more of the recording media by hanging one end of the sheet on the other end of the sheet. Since the storage unit covers one or more recording media by hanging one end of the paper on the other end of the paper, the recording medium package can be easily formed without using an adhesive.

Further, it is preferable that the holding section has a conductive member at least in a portion in contact with the recording medium. Since the holding section is formed of a conductive member at least in a portion in contact with the recording medium, static electricity generated by friction with the recording medium can be prevented, and more stable conveyance of the recording medium can be secured. it can. Further, it is preferable that the storage section can be mounted on the recording apparatus in a state where the storage section is separated. Since the storage unit can be attached to the recording device in a separated state, the operator of the recording device can operate the recording device simply by simply separating the recording medium package and mounting it on the recording device. Handling of the recording medium to the device becomes easy. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, a recording medium package according to an embodiment of the present invention will be described with reference to the drawings.

The recording medium package 1 is entirely made of paper and is 55 mm long, 77 mm wide, and 5 mm thick. It is a thin rectangular parallelepiped of about mm, and can accommodate about 20 sheets of thermal paper 19 (see Fig. 2) as an A8 size recording medium. The recording medium package 1 includes a holding portion 3 (see FIG. 2) for holding the thermal paper 19 and a storage portion 23 for storing a plurality of thermal papers 19 so as to cover at least the holding portion 3. The storage section 23 is composed of a lid section 13 and a base section 15 with a straight perforation 17 as a boundary.

As shown in FIG. 2, the recording medium package 1 has a configuration in which the lid 13 can be separated from the base 15 with a straight perforation 17 as a boundary. When the user cuts the lid 13 along the perforation and removes it from the base 15, a part of the holder 3 and a part of the thermal paper 19 held by the holder 3 are exposed. Since the perforations 17 are formed in a straight line, the user can easily separate the storage portion 23 simply by holding and pulling the lid portion 13.

Note that the recording medium package 1 can be mounted as it is in a paper storage unit of a printer as a recording device with the lid 13 removed.

When the thermal paper 19 is held in the base 15 of the recording medium package 1 and set in the printer, the pickup roller 33 (see FIG. 5) of the recording medium package 1 Covers the paper feed side 19 a of the thermal paper 19 in contact. Therefore, when the paper compartment 13 is removed when the printer is loaded in the paper storage section, the paper feed side 19 a of the thermal paper 19 appears, and the pickup roller 33 becomes the base 1 of the recording medium package 1. It comes into contact with the thermal paper 19 held in 5. On the other hand, the holding portion 3 protrudes from the base 15 on the back side opposite to the side where the pick-up roller 33 is in contact with the thermal paper 19 (this surface is referred to as the front side in this embodiment). However, the holding portion 3 is an underlay for supporting the thermal paper 19. After removing the lid 13, the recording medium package 1 according to the present embodiment can be mounted in the paper storage of the printer while the thermal paper 19 is held by the holder 3.

As shown in FIG. 3, the recording medium package 1 in the present embodiment is formed by one sheet of paper, and is formed by cutting with a mold (for example, pressing). Therefore, while burrs are generated on the back side (back side of the paper) of the recording medium package 1, the front side (front side of the paper) forms a so-called sagging portion where no spar occurs. The perforations 17 are also formed linearly in the developed view of FIG. In the exploded view of the recording medium package 1, the recording medium package 1 has a holding portion 3 for holding the thermal paper 19, and a storage portion including the upper portion 5, the left side portion 9, the right side portion 7, and the center portion 11. At the end of the left side 9 and the end of the right side 7 are provided hooks 9A, 7A which project in opposite directions and can be engaged with each other. To assemble the recording medium package 1, first, with the thermal paper 19 placed on the back side of the center part 11, bend the holding part 3 along the two-dot chain line toward the back side of the paper, and then The left side part 9 and the right side part 7 are folded along the two-dot chain line toward the back of the paper along the two-dot chain line so as to cover 3, and the hook part 9A at the end of the left side part 9 and the hook part at the end of the right side part 7 Hang the attachment part 7 A and fix it. Then, the recording medium package 1 is completed by inserting the upper part 5 into an area 21 (see FIG. 4) formed by the hooked left side part 9 and right side part 7. FIG. 4 is a set diagram of the completed recording medium package 1 in the present embodiment.

As described above, since the recording medium package 1 according to the present embodiment is formed from one sheet of paper, it can be easily formed, and the end of the left side surface 9 is connected to the end of the right side surface 7. To cover multiple thermal papers 19, making it easy to use a recording medium package without using an adhesive. Di 1 can be formed.

FIG. 5 is a view showing a state in which the recording medium package 1 according to the present embodiment is mounted on the paper storage section 37 of the printer 30 and the thermal paper 19 is fully loaded, and FIG. FIG. 6 is a diagram showing a state in which the recording medium package 1 in the embodiment is mounted on a printer 30 and the number of thermal papers 19 is reduced.

This printer 30 is a thermal printer including a thermal head 31 and a platen roller 32. Therefore, a plurality of thermal papers 19 are stored in the recording medium package 1, and when the lid 13 is cut out along the perforation, the leading end 19 a of the thermal paper 19 appears. The surface 19b of the thermal paper 19 to which the thermal material is applied is directed upward. The tip 19 a of the thermal paper 19, which appears when the lid 13 is cut off, comes into contact with the pickup roller 33 when attached to the printer 30. Therefore, when the pickup roller 33 rotates in the paper feeding direction, a force in the paper feeding direction acts on the thermal paper 19, and the thermal paper 19 is sent out in the paper feeding direction, that is, in the direction of the thermal head 31. At this time, even if a plurality of thermal papers 19 are sent out, the leading ends of the thermal papers 19 come into contact with the separation wall 34, so only the thermal paper 19 in contact with the uppermost pick-up roller 33 is separated and transferred to the thermal paper. It is sent out in the direction of head 31.

In this embodiment, in order to secure the contact pressure between the pickup roller 33 and the thermal paper 20, the potom plate 36 is pushed up in the direction of the pickup roller 33 by the spring 35. . Then, as shown in FIG. 6, even when the thermal paper 19 is consumed and its thickness is reduced, the thermal paper 19 is pressed against the pickup roller 33 with a substantially constant pressure. Further, when the recording medium package 1 of the present embodiment is employed, the holding portion 3 is inserted between the final thermal paper 19 c and the bottom plate 36 like an underlay. The front side of the holding section 3 is Since it has the same friction coefficient as the front side, the same thermal force acts on the final thermal paper 19c as on other papers, so that the last few sheets are not picked up and fed at the same time.

FIG. 7 is an enlarged view showing a state in which the recording medium package 1 according to the present embodiment is mounted on the printer 30 and the thermal paper 19 is fully loaded, and FIG. 8 is a recording medium according to the present embodiment. FIG. 3 is an enlarged view showing a state where the package 1 is mounted on the printer 30 and the number of thermal papers 19 is reduced.

7 and 8, the holding portion 3 is arranged such that, of the ends formed by cutting with a mold, the surface on the side corresponding to the sag portion comes into contact with the thermal paper 19. . This is performed to stabilize the transfer of the thermal paper 19, and in particular, to stably transport the final thermal paper 19.

Here, when the amount of the thermal paper 19 mounted on the recording medium package 1 is sufficient, the thermal paper 19 and the recording medium package 1 are oriented substantially horizontally as shown in FIG. However, when the amount of the thermal paper 19 mounted on the recording medium package 1 decreases, as shown in FIG. 6, the recording medium package 1 moves around a predetermined position of the box portion of the recording medium package 1. It turns and tilts. The portion of the holder 3 protruding in the transport direction from the opening end of the recording medium package 1 box is no longer affected by the gravitational force of the thermal paper 19, so that the protrusion of the holder 3 The part bends upward from the open end of the package box. At this time, if the length of the holding section 3 in the thermal paper transport direction is shorter than the dimension of the thermal paper 19 in the transport direction, the upwardly bent portion becomes steeply inclined, and the leading edge of the holding section 3 becomes sharp. The thermal paper 1 comes into contact with the thermal paper 1 in line contact, and there is a possibility that the transport of the thermal paper 1 may become a resistance.

However, in the present embodiment, since the length of the holding section 3 in the thermal paper transport direction is approximately the same as the dimension of the thermal paper 19 in the transport direction, the recording medium package Even when the number of thermal papers 19 mounted on the cartridge 1 decreases, the part of the holder 3 that projects from the opening end of the recording medium package 1 box toward the conveyance direction does not have a steep inclination. As shown in (2), the holding section 3 can secure a certain degree of surface contact with the thermal paper 1.9, and the transport of the thermal paper 19 can be more stable.

Note that, in the present embodiment, the holding section 3 has been described as being simply formed of paper, but the holding section 3 is a portion that is constantly rubbed by the thermal paper 19 transported by the pickup roller 33. The possibility of triboelectric charging is high. Therefore, the transfer of the thermal paper 19 can be stabilized by applying or containing a conductive member (for example, carbon) in the portion of the holding section 3 where the thermal paper 19 rubs.

If a conductive member is coated or included in at least a portion of the holding portion 3 where the thermal paper 19 abuts, static electricity generated by friction with the thermal paper 19 can be prevented, and a more stable thermal paper 19 transports can be secured.

Also, in the recording medium package of the present embodiment, the form in which the thermal paper is mounted has been described, but a recording medium such as plain paper, carbon paper, or OHP paper other than the thermal paper is mounted in the recording medium package. You may. Industrial applicability

It can be used for various devices such as an image forming apparatus using a sheet-shaped recording medium, for example, a printer, a facsimile, a copying machine, and the like, and is highly useful.
