Abstract

PURPOSE:To prolong the length of supporting a paper sheet with a table surface at time of use and make the paper sheet easily insertable into a paper sheet inserting port as well as to control a leakage of noise being produced in a box body in reducing an opening area of this paper sheet inserting port by attaching a slide cover to the box body free of movement in the longitudinal direction. CONSTITUTION:At time of use, a slide cover 18 is slid in the rear, thereby exposing a table surface 11, and the length of supporting a paper sheet 3 is lengthened by this table surface 11. With this formation, the paper sheet 3 is easily insertable into a paper sheet inserting port 13, and an opening area of this paper sheet inserting port 13 is reduced so that a leakage of noise being produced in a box body is controllable. In addition, since the paper sheet inserting port 13 is opened in front of the box body 1, dust penetration can be lessened. In addition, the slide cover 18 is slid forward, whereby the table surface is covered and, what is more, an external form of the box body 1 is maintainable in a simple form with no irregularity.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to industrial applications such as printing devices, image input devices, copying machines,
This invention relates to a paper sheet insertion device for office machines such as facsimile machines.

Conventional technical office machines are equipped with various information processing sections for printing, copying, image input, etc., and a paper sheet transport section for transporting paper sheets to this information processing section, depending on the purpose, inside the housing. are doing. There are two types of paper sheet insertion slots for inserting paper sheets: one is formed on the -E surface of the casing, and the other is formed on the front surface of the casing. Those that push paper sheets through the paper sheet insertion slot formed on the top surface of the casing,
A guide plate is provided that extends to the upper part of the rear so that the paper leaves can fall down.
When paper sheets are inserted from the front of the housing, it is desirable to guide the paper sheets by increasing the length of the table that supports them.

Problems to be Solved by the Invention When inserting paper sheets from the top surface of the casing, it is necessary to attach and remove the guide plate, and unless you look into the paper sheet insertion slot from the top of the casing, the insertion end of the paper sheet will be damaged. Since the edge (lower edge) is not visible, it becomes difficult to insert the paper sheet straight, and furthermore, dust easily enters the paper sheet insertion slot from above.

Further, in a case where a table is provided in the case for inserting paper sheets from the front side of the case, the case protrudes by the table, making it impossible to simplify the shape of the case.

Means for Solving the Problems A housing in which an information processing section and a paper sheet transport section are built has an opening that opens the periphery of the information processing section and the paper sheet transport section, and a paper sheet is placed on the top surface. a front plate having a table surface and a protrusion protruding forward from the lower part of the opening, the lower edge of which faces between the table surface and the front plate to form a slit-shaped paper sheet insertion opening; A slide cover having an upper plate extending rearward from the upper edge of the front plate was attached to the housing so as to be movable in the front-rear direction.

When in use, the table surface is exposed by sliding the slide cover backwards, and the length of the table surface supporting paper sheets is increased, allowing the paper sheets to be easily inserted into the paper sheet insertion slot. This makes it possible to reduce the opening area of the paper sheet insertion slot and suppress the leakage of noise generated within the housing.Furthermore, since the paper sheet insertion slot opens at the front of the housing, it is possible to reduce the intrusion of dust. Furthermore, by sliding the slide cover forward, it is possible to cover the table surface and maintain the external shape of the casing in a simple shape with no irregularities.

Example An embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, inside the housing 1, there are provided a printing section 2, which is an information processing section, and a sheet transport section 4, which transports sheets 3. The printing unit 2 includes a platen 5, a print head 6 facing the platen 5, and an ink ribbon 7 between them.
It consists of a ribbon cassette 8 that supplies the ribbon. In addition, case 1
has an opening 9 that opens the periphery of the printing section 2 and the sheet transport section 4, and a table surface 1 on which the sheet 3 is placed.
1 and protruding forward from the lower part of the opening 9, and a slit-like horizontally elongated sheet discharge port 12 opening at the center of the upper surface. The sheet conveying section 4 includes a plurality of pairs of feed rollers 14 arranged in a sheet path 13 extending from the table surface 11 through the front surface of the print head 6 to the sheet discharge port 12. 1
The drive side of 4 and the platen 5 are connected to a motor 17 by a transmission 16 including a belt 15.

A slide cover 18 that covers the opening 9 is attached to the housing 1 so as to be movable in the front-rear direction along the direction in which the paper sheet 3 is inserted. This slide cover 18
consists of a vertical front plate 19 and an upper plate 20 extending rearward from the upper edge of the front plate 19, and between the lower edge of the front plate 19 and the table surface 11 is a slit-shaped horizontally long paper sheet. An insertion port 21 is formed. Note that, although not shown, functional parts such as a drive unit for driving the Moe inscription printing unit 2 are housed inside the protrusion lO of the housing 1.

In such a configuration, as shown by the solid line in FIG. 1 and FIG. By increasing the length at which the paper sheet 3 is supported at 11, the paper sheet 3 can be easily inserted into the paper sheet insertion slot 21. Thereby, the opening area of the sheet insertion slot 21 can be reduced, and therefore, leakage of noise generated within the housing 1 can be suppressed.

Moreover, since the paper sheet insertion slot 21 is opened at the front of the housing 1, the intrusion of dust can be reduced.

In addition, by sliding the slide cover 18 forward as shown in the imaginary line in FIG. 1 and in FIG. be able to.

Effects of the Invention Since the present invention is configured as described above, when in use, the table surface is exposed by sliding the slide cover backward, and the length of the table surface supporting the paper sheet is increased, and the paper sheet is It can be easily inserted into the leaf insertion slot, which makes it possible to reduce the opening area of the leaf insertion slot and suppress the leakage of noise generated inside the housing. The front opening reduces dust intrusion, and by sliding the slide cover forward, you can cover the table surface and maintain a simple exterior shape with no irregularities. It has the effect of being able to.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention; FIG. 1 is a longitudinal side view, FIG. 2 is a side view with the table surface open, and FIG. 3 is a side view with the table surface covered. It is.
