CONSTITUTION:When a cut sheet is used, a separator 4 is set in a standing position and the sheet is made slide on the surface of a paper guide 3 and fed from the direction of the arrow A to the periphery of a feed roller 13. And, recording or reading is carried out by a head 14 while the fed sheet is conveyed by the feed roller 13 and the sheet is discharged in the direction of the arrow B. When a roll sheet is used, the separator 4 is set6 in a laid position, and the roll sheet is inserted from the direction of the arrow C through the underside of a positioning member 11, and fed from the direction of the arrow D toward the feed roller 13 through an opening 15 in between the back side on the lower end part of the paper guide 3 and a body case 2. After recording or reading is carried out by the head 14 while the sheet is conveyed by the feed roller 13, it is discharged from the direction of the arrow B.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Technical Field] The present invention relates to a shape-variable paper stand used in recording devices, image reading devices, and the like.

[Conventional technology]

2. Description of the Related Art In recording devices or image reading devices such as printers and facsimiles, a paper stand is sometimes attached to smoothly supply and discharge recording media such as sheets, paper, and manuscripts.

This paper stand is generally configured to guide the sheet so that it does not fall over when being fed toward the sheet 1/feeding mechanism within the apparatus and when coming out of the apparatus.

By the way, when a conventional paper stand guides sheets of different lengths, the entire length of the paper stand]-' (
The structure was designed to accommodate this by changing the slope angle and height.

On the other hand, in large-scale recording devices and reading devices produced in small quantities, in order to keep the initial investment low, the paper stand is made of a sheet metal structure rather than a mold, thereby reducing costs.

However, conventional paper stands with a sheet metal structure change the overall inclination angle and height, so they require a mechanism for attaching and detaching the entire device, a hinge means for collapsing, and a storage place for the metal rod. The problem was that the structure was complicated and large, and as a result, it was difficult to reduce costs.

〔the purpose〕

An object of the present invention is to solve the problems of the prior art, to have a simple structure even if it is a sheet metal structure, and to smoothly supply and discharge sheets to and from an apparatus body even when sheets have different lengths. An object of the present invention is to provide a wet paper stand 1'.

[Means to achieve the purpose]

The invention consists of a plate-shaped paper guide that is removably attached to the main body case at a predetermined angle, and a metal rod, and the paper guide is positioned at an angle of 100 degrees in a standing position approximately extending from the paper guide and in a lying position approximately horizontally with respect to the paper guide. With a paper stand consisting of a seperately attached sepa I note,
This aims to achieve the above objectives.

〔Example〕

The present invention will be specifically described below with reference to the drawings.

1 is a longitudinal cross-sectional view of a paper stand according to an embodiment of the present invention, FIG. 2 is a front exploded irl view of FIG. 1, and FIG. 3 is a rear view of FIG. 1.

1 to 3, the paper stand 1 includes a plate-shaped paper guide 3 that is detachably attached to the main body case 2 at a predetermined inclination angle, and a plate-shaped paper guide 3 that is attached to the paper guide so that the angle can be changed ((t B-1 separator 4
It is made up of.

The paper guy [-3 is attached to the flange portions 5.5 formed on both sides of the main body case 2 by pushing and fitting the fixtures 6.6 into the square holes 7.7 formed in the main body case 2. It is removably attached to 2. The paper guys 1 and 3 shown in the figure are made of steel plate after forming it. It is constructed by assembling with a U-connection or the like.

On the other hand, the separator 4 is formed by molding and welding metal rods. The illustrated separator I/-4 has a structure in which three guide men halves A, 7B, and 7C formed in an inverted tJ shape are welded to a horizontal shaft 8 and integrated.

Therefore, the separator 4 has two positions with respect to the paper guide 3: a standing position approximately on the extension of the paper guide as shown by the solid line in FIG. It is installed so that the angle can be changed.

On the back surface of the paper guide 3, as shown in FIGS. 1 and 3, holding portions +, I']O (three locations) forming a slide hole 9 for holding the horizontal axis 8 of the separator 4, and A positioning member 11 is secured to the lower end of the separator 4 and protrudes so as to come into contact with the lower end of the separator 4 and hold the separator in an upright position.

Further, at the upper end bent portion of the paper guide 3, the guide men halves A, 7B, 7 are attached at the standing position of the separator 4.
Notches 12 where C engages (6 locations in total in the example shown)
is formed.

Therefore, as shown in the solid line in FIG. 1 and in FIGS. 2 and 3, the separator 4 engages each of the guide members 7A, 7B, and 7C with each notch 12, and connects their lower ends to the positioning member 11. It is held in a standing position by hitting it. Note that the horizontal shaft 8 is always held movably downward in a slide hole 9 that is elongated in the vertical direction.

When changing the angle of the separator 4 to the twisted position (double-dashed line in FIG. 1), each guide member 7A, 7B, 7
When the lower end of C is removed from the positioning member 11 and rotated until it becomes almost horizontal, each guide member half A is removed as shown by the two-dot chain line.

The lower portions of 7B and 7C contact the back surface of the paper guide 3 and are held in the folded position.

By lifting the separator 4 from the folded position, the angle can be changed to the standing position again.

When the paper guide 3 is attached to the main body case 2, a space is formed between the lower side of the positioning member 11 and the upper surface of the main body case 2, as shown in FIG. An opening (or passage) for supplying sheets between the back surface of the lower end and the main body case 2 15
is starting to form.

Next, the feeding and discharging of sheets will be explained with reference to FIG.

When using a normal cut sheet, the separator 4 is kept in a standing position, and the sheet is fed to the circumferential surface of the feed roller 13 from the direction of arrow A by sliding the surface of the paper guide 3.

The supplied sheet is recorded or read by the head 4 while being conveyed by the feed roller 13, and is then outputted in the direction of arrow B.

When using a long cut sheet, place the separator 4 at the wrinkling position (the position indicated by the two-dot chain line in FIG. 1).

As a result, guide member 7A is almost horizontal to sea 1.
, 7B, and 7Cj, even if the sheet is weak or long, the feed roller 1
Through 3, a system for smooth supply and discharge is created,
Sheet jams can be prevented.

When using a roll sheet, place the separator 4 in the lying position, insert the roll sheet from the direction of arrow C through the bottom of the positioning member 11, and then press the underlined back side of the paper guide 3 and the main body case 2. The feed roller 13 is fed from the direction of force (arrow I) through the opening 15 between the rollers (Jt).

The recording material is recorded (or read) by the head 14 while being conveyed by the feed roller 13, and is then discharged in the direction of arrow B.

In the case of this roll sheet (including the case of a long paper sheet), after being discharged from the direction of arrow B, as shown by arrow E, it goes over the earthen floor 1 of paper guy 1" 3 and reaches the upper position. is guided in the opposite direction along the upper surface of the separator 4.

In this way, when the roll sheet 1 is in use, the separator 4 prevents the sheets reciprocating from rubbing against each other, and prevents problems in the sheet 1 feeding due to the generation of static electricity.

〔effect〕

As is clear from the explanation below-4-, according to the present invention,
It is made up of a plate-shaped paper guide that can be attached to and removed from the main body case at a predetermined angle, and a metal rod that is attached to the finger, and the angle can be changed to a standing position and a substantially horizontal lying position. Since the paper stand is constructed with a separator that can be removed, it has a simple structure and can be used to hold various sheets of different lengths and stiffness.
- Even when using roll sheets (including roll sheets 1 to 1), it is possible to easily feed and discharge the sheets.
