Abstract

PURPOSE:To simplify a discharge mechanism, by a method wherein, a belt is so disposed longitudinally to a printer body as to face a printing paper mount, and a recording paper discharge member fixed to the belt is moved together with the belt to press the trailing edge of the recording paper for discharging the recording paper from a recording paper discharge port. CONSTITUTION:A recording paper in a paper feed case 3 is moved rightwards in the width direction of a printer body to be fed to a printer device part A and printed therein, thereafter being carried leftwards in the width direction of the printer body by a feed roller 20 to be loaded on a recording paper mount 21. A pulley 23 is driven through a worm gear mechanism 25 due to the actuation of a motor 25, whereby a belt 22 is peripherally rotated and a recording paper discharge member 27 mounted on the belt 22 moves toward the front of the printer body along a groove 21b while pressing the trailing edge of the recording paper to discharge the recording paper 5 from a recording paper discharge port 6 on a front panel 7a. In this manner, two or more drive mechanisms are not required, and a recording paper discharge is realized with a remarkably simple mechanism.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a cassette insertion slot for inserting an ink ribbon cassette, and a slot for inserting a sheet of recording paper! i-paper insertion slot,
The present invention also relates to a recording paper ejection mechanism in a front-operated printer in which a recording paper ejection port for ejecting printed paper is provided on the front of the printer main body.

[Prior Art] Full-color printers capable of multilevel g expression are generally used as hard copy devices for making hard copies of images on displays such as televisions. Although it is preferable to use an operator-operated type printer, in conventional printers of this type, the inlet/outlet for the paper feed case that stores the sheet-like recording paper, and the ejection outlet for the recording paper after printing are provided on the front of the printer body. However, the ink ribbon cassette was designed to be inserted from the side of the printer body due to the paper feeding path in which the recording paper was fed from the front and ejected from the front. Since this is inconvenient to operate, the applicant has created a cassette insertion slot 2 for inserting the ink ribbon cassette 1, and a paper feed case, as shown in Figure t54, in order to enable all operations from the front of the printer main body. A front-operated printer 7 has been developed in which a paper feed case slot 4 for taking in and taking out a paper feed case 3 and a recording paper ejection port 6 for discharging a printed recording paper 5 are all provided on the front panel 7a of the printer body. txt
, A to explain, 9 is a feed roller that sends the printed recording paper 5 to the left in the width direction of the printer main body (in the direction of arrow (A)), 10 is a recording paper base, and 11 is perpendicular to the feed roller 9. The ejection roller 11 is disposed in the direction (that is, parallel to the width direction of the printer main body). , and a twist/id 1 for rotating the arm 12 around the shaft 16.

In this way, the conveyed recording paper after printing is turned by the discharge roller 11 by 9 degrees in the direction of the arrow (b) and j, and is discharged from the curved recording paper discharge port 6.

[Problems to be Solved by the Invention] Since the recording paper feeding direction in the printing device section is perpendicular to the direction in which the ink ribbon cassette is inserted, it is necessary to adopt a front scratching type structure in which the ink ribbon cassette is inserted from the front. However, in the conventional mechanism using the ejection roller 11, when the recording paper is fed by the feed roller 9 after printing, the ejection roller 11 must be changed by 90 degrees as described above. The structure is complicated and the device is complicated because it requires a complicated operation of raising the discharge port 211, lowering the discharge port 211 when the feeding of the feed roller 9 is completed, and then driving the discharge port 211 to rotate. There is a drawback of increasing the size.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to simplify and downsize the structure of recording paper discharge m, hM in a front-operated printer.
