JPS59194952A - Two-stage type business form accommodating box - Google Patents

Abstract

PURPOSE:To permit two kinds of business forms having different size to be accommodated into an accommodation box by forming concaved parts at the front and rear parts of the both outside wall of a business sheet cassette and installing a hinge part which is fitted into said concaved part and rotatably holds the business sheet cassette into the business-sheet accommodating box. CONSTITUTION:Four concaved parts 2 for rotatably inserting a business sheet cassette 1 into the hinge part 5 of a business sheet accommodating box 3 are arranged at the front and rear parts on the both sides of the business sheet cassette 1. Said business sheet accommodating box 3 is equipped with a stopper 4 for engaging the upper part of the upper-stage business sheet cassette 1 when said business sheet cassette 1 is not used, in the upper part on the both sides, besides the above-described hinge part 5. Therefore, when the upper-stage cassette 1 is used, the concaved part 2 in each rear part of the both cassettes 1 and 1' in the upper and the lower stages is fitted onto the above-described hinge part 5, and the business sheet in the upper-stage cassette 1 is press-attached onto a feed roller 6 by the urging force of a spring 7. While, when the lower-stage cassette 1' is to be used, the upper-stage cassette 1 is pulled-out, and the hinge 5 is fitted into the concaved part 2 in the front part.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a paper storage container used in a copying machine.

Conventional paper storage containers used in prior art copying machines can only store one type of paper in one container. Therefore, a number of paper storage containers are required depending on the size of paper to be used, and the paper storage containers must be replaced frequently, which is also inconvenient in terms of container storage.Purpose of the InventionThis Invention It is an object of the present invention to provide a paper storage container for a copying machine that can reduce the number of replacement operations and facilitate storage.

Structure of the Invention The present invention allows two types of paper of different sizes to be stored in one container.

In other words, a part of the trap provided on the side plate of the storage container,
The hinge part and the spring mechanism provided on the bottom plate allow the upper and lower two
Two cassettes are housed in each stage, and the paper in the cassette corresponding to the size of the paper to be used is pressed against the feed roll either directly by the spring mechanism or via the lower cassette.

Embodiments An embodiment of the storage container of the present invention will be described based on the accompanying drawings.

FIG. 1 is a perspective view of a paper cassette 1 stored in a paper storage container of the present invention, and FIG. 2 is a perspective view of a paper cassette 1 of the present invention.
FIG. The paper cassette 1 is provided with a total of four parts on both sides, front and rear, for rotatably fitting the cassette to the hinge parts 5, 5' of the storage container. In addition to the hinge portion 5.5', the storage container 3 is provided with stoppers 4.4' at the top of both sides for hanging the upper part of the upper cassette when it is not in use.

Figures 3 and 4 are side views of the storage container of the present invention in which paper cassettes are stored in two stages, with Figure 3 showing the use of the upper cassette, and Figure 4 showing the use of the lower cassette. Represents the state of being.

Although not shown in FIG. 2, a spring mechanism (the leaf spring 7 in FIGS. 3 and 4) is provided at the bottom of the storage container. When the upper cassette is used, the hinge 5.5' of the storage container fits into the recess at the rear of both the upper and lower cassettes.
The paper stored in the upper cassette is moved to the feed roll 6 by the restoring force transmitted from the spring 7 via the lower cassette.
The topmost sheet of paper is conveyed one by one by the rotation of the feed roll.

When using the lower cassette, when the upper cassette is pulled out and the hinges 5 of the storage container are fitted into the front four parts, the action of the spring transmitted from the stopper 4 and the lower cassette (thus, the upper cassette is held). On the other hand, the paper stored in the main cassette is directly pressed against the feed roll 6 by the restoring force of the seven springs, and as the roll rotates,
The sheets are transported one by one.

When the unused upper cassette is to be used again, the cassette may be pushed into the storage container 3 and the hinges 5 fitted to the four rear parts.

Effects of the invention The number of paper replacement operations is halved, and the number of paper storage containers required is also halved, which is extremely convenient from a storage standpoint.
