Abstract

PURPOSE:To prevent sheets from absorption of moisture during storage and to enable the sheets to be separated one by one during feed of the sheets, by a method wherein a sheet feed opening and a separating member are located to a cartridge body containing the sheets, and the sheet feed opening is closed with a member which is openable. CONSTITUTION:A cartridge body 1 is formed into an enclosed hollow boxform body surrounded with vertical, lateral, and longitudinal walls 1a-1f, and sheets 2 are contained in the hollow part thereof. This prevents the sheets 2 from absorption of moisture through maintenance of airtightness. Perforations 3 are formed on the sheet delivery side of an upper wall 1a, a front wall 1e, left and right walls 1c and 1d to form an opening part 4. In a condition in which the opening part 4 is removed, separating members 5, matching the stifness of the sheet 2, are attached to the corner parts formed by the left and right walls 1c and 1d, and the front wall 1e. This prevents the sheets 2 from absorption of moisture during storage, and enables the sheets 2 to be reliably separated one by one during feed of the sheets.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a paper car (IJ) that is loaded into the main body of a copying machine, printer, etc. and supplies paper thereto.

Conventional technology Conventionally, paper for copying machines, printers, etc. is fed by a paper tray attached to the main body of the copying machine, printer, etc., or by setting paper in a paper feed cassette and feeding one sheet by a paper feeding mechanism provided on the main body side. I try to feed the paper one by one.

These paper trays and paper feed cassettes are equipped with separation claws that separate the sheets one by one during paper feeding, but these separation claws are used to separate all types of paper with different stiffness. Therefore, depending on the paper, there were problems such as folding at the leading edge of the paper or failure to feed the paper.

In addition, conventionally, the number of sheets of paper was 100 sheets, 500 sheets, or 100 sheets.
The sheets are packaged in moisture-proof paper, etc., and when replenishing paper into a copier, printer, etc., it is necessary to open the aforementioned package and reload the paper into the paper tray or paper cassette. The problem is that the work becomes troublesome.

Also, the paper tray and paper cassette are copy machine.

The problem is that it is necessary to prepare as many paper sizes as the types of paper used in the printer, etc.

OBJECTS OF THE INVENTION It is an object of the invention to reliably separate sheets and feed them one by one when feeding them, to easily replenish the sheets, and to prevent the sheets from absorbing moisture when stored.

Components of the Invention A cartridge body containing paper is provided with a separation member.

Embodiment FIG. 1 is a perspective view of the overall appearance, and the cartridge body 1 has upper and lower sides, left and right walls, front and rear walls 1α*1bel'+ltt, is,
It is a closed hollow box-like body surrounded by 1f, and the paper 2 is stored in the hollow interior. Additionally, airtightness is maintained to prevent the paper 2 from absorbing moisture.

Perforations 3 are continuously formed on the paper feeding section side of the upper wall 1α, the front wall 1e, the left and right walls 1r, and Id to form an opening section 4.

Note that a thin Mylar film (not shown) is pasted on the back (inner surface) of the part where the perforation 3 is located to prevent outside air from coming into contact with the paper 2 from the perforation 3 to maintain airtightness. There is.

FIG. 2 is an external perspective view of the opening portion 4 removed from the cartridge body 1, showing the left and right wall ICs.

1d and the front wall 1e are provided with separation claws 5 which serve as a special separation member suitable for the stiffness of the paper 2, and the paper 2 is exposed in the paper feed opening 6. .

Therefore, when feeding paper, 3 perforations are provided at the opening section 4.
Tear it off and load it into the main body A of a copying machine, printer, etc. as shown in Fig. 3, position the paper feed row 27 provided on the main body A side in the paper feed opening 6, and insert it into the paper feed roller ruff. Separation claw 5
Separate the sheets one by one and feed them.

In this way, the paper is separated and fed one by one by the separation claw 5 provided in the cartridge main body l that matches the stiffness of the paper 2, so paper folds may occur at the leading edge of the paper, and paper feeding errors may occur. Paper can be reliably separated and fed one by one without causing any problems.

Also, replenishment of paper for copying machines, printers, printers, etc.

car) Unseal part 4 of the IJ body l and use the copy machine.
Since all you have to do is load it into a printer, etc., it is extremely easy to replenish paper.

In addition, since the cartridge body 1 is provided with the separation claws 5, there is no need to prepare multiple types of paper trays or paper feed cassettes each equipped with a pair of separation claws with different spacing depending on the paper size. Copy machines, printers, etc. can be made cheaper.

Although not shown in the drawings, there is a pressure applying member configured such that the lower wall 1h of the cartridge main body 1 is raised according to the paper feeding means of a copying machine, printer, etc., and this lower wall I6 is provided on the main body A side. In addition, a bottom plate is provided in the cartridge body j so as to be able to swing upwards, and a portion of the lower wall 1b corresponding to the pressure applying member is torn off. It is also possible to lift the bottom plate by a pressure applying member from a portion.

Moreover, when the paper is used up, the cartridge main body I is taken out, a new cartridge main body 1 is unsealed, and a new cartridge main body 1 is loaded. 1. Also, as shown in Fig. m4, a friction member 8tl serving as a separation member is provided at the upper end of the front wall 1e of the cartridge main body 1,
When loaded into a copying machine, a printer, etc., the friction member 8 is brought into pressure contact with a paper feed belt 9 that serves as a paper feed member, and the friction member 8 has a friction coefficient between the paper feed belt 9 and the paper 2 that also has a friction coefficient with the paper. The structure may be such that the coefficient of friction with the member 8 is smaller, and the paper 2 may be separated and sent out using the difference in the friction coefficient described above.

In FIG. 4, IQ is a bottom plate, 11 is a pressure applying member, and the lower wall 1i5 is an opening part 12 where the pressure applying member 11 faces.
is formed.

Note that FIG. 5 is a sectional view of an embodiment in which the paper feeding member is a paper feeding roller 9.

Further, as shown in FIG. 2, a cartridge main body 1 is formed in which a paper feed opening 6 is formed in advance, and this cartridge main body 1 is sealed and packaged in a bag 13 as shown in FIG. It is also possible to tear the bag 13 and take out the cartridge body 1 as shown in FIG.

Effects of the Invention Since the cartridge main body is provided with a separation member that is suitable for the stiffness of the paper stored therein, the paper can be separated reliably without folding the paper or making mistakes in feeding the paper. In addition to being able to feed sheets one by one, the paper can be easily replenished, and furthermore, the paper does not absorb moisture when stored.
