Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a lid that also serves as a paper feed plate for a printer used in a printing device such as an electronic printer.

[Prior art]

Generally, in the case of an electronic printer, a lid member 13 covering the internal mechanism of the electronic printer 12 is placed between the paper feed port 10 and the paper ejection port 11 of the paper A, as shown in FIG. It is installed integrally with the

Therefore, since there is nothing to support the paper A that is ejected from the ejection port 11, the paper may curl up while being ejected, or become tangled in the paper feed port 10 after being ejected to the paper feed port 10. In addition to the paper A being bent or damaged, there were other problems such as causing the printer 12 to malfunction.

As a countermeasure for this, there is a method in which the paper A that is ejected from the output port 11 of the printer 12 is attached separately to the upper case 14 of the printer 12, and a splint is attached to the paper A, but in this case, the splice is attached. In addition to being time-consuming, a separate place is required to store and store the plate.

[Purpose of this invention]

This invention was developed to solve the above-mentioned problems, and its purpose is to automatically eject the lid from the ejection port when paper is fed, without the need for a separate plate. A convenient paper feed for printers that serves as a backing plate for the paper that is ejected, prevents damage to the paper that is ejected, and also allows you to check the print on the paper that has been printed and is ejected, making it possible to print more accurately. The object of the present invention is to provide a structure for a lid that also serves as a sprinkling plate.

[Summary of the invention]

In order to achieve this purpose, the present invention provides a rotatable cover between the paper feed port and the paper output port provided in the upper case of the printer so that it can be used also as a splicing plate. means for detecting rotation control of the lid;
This feature is characterized in that it can be automatically unlocked using a lock release means or the like.

[Example of the present invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment in which the structure of a paper feed plate and lid for a printer according to the present invention is applied to an electronic printer will be described with reference to the drawings.

FIG. 1A is a perspective view of an embodiment of the present invention, and FIG. 1B is an enlarged sectional view taken along the arrow X in FIG. 1A.

FIG. 2A is a perspective view showing the state in which the paper feeding plate and cover of the printer of the present invention is used, and FIG. 2B is an enlarged sectional view of the section indicated by the arrow X in FIG. In FIGS. 1 and 2, 1 is an electronic printer.

The electronic printer 1 includes a keyboard 3, a print display section 4, and a paper feed port 10 for paper A on an upper case 2.
It has a discharge port 11. A lid 5 between a paper feed port 10 and a paper discharge port 11 for paper A is pivotally attached at its end to the upper case 2 so as to be rotatable. That is, the lid body 5
The free end side 5a is formed into a substantially hook shape so that the paper A can be easily inserted, and the base side thereof has a rotating cam 6.
is integrally attached to the

The tip 6a of the cam 6 is urged in the direction of the arrow by a spring 7, and when the paper is not fed, the arm 8 of the locking means 8
It is locked at a. This arm 8a is locked by the shaft 8c of the solenoid 8b of the locking means 8.
is released by being pulled to the left.

A sensor 9 (a reflective photo sensor is used here, but is not limited to this) is provided near the paper feed port 10 as a detection means for sending a detection signal to the solenoid 8b.

Note that the top surface 5a of the lid 5 is locked by a locking member 15, so that the paper A to be ejected from the lid 5 is secured to the paper feed port 10.
The inclination angle is set at a height that does not get tangled with the keyboard 3 and at an angle that makes it easy to see the print on the paper A that is printed and discharged from the keyboard 3 side. Further, in the figure, 16 is an ink ribbon cartridge for printing, 17 is a platen used as a support plate for paper A, and 18 is a feed plate for paper A.

[Operation of the present invention]

According to the present invention having the above configuration, the paper A is
When the paper A is inserted, the sensor 9 detects the paper A, the detection signal is sent to the solenoid 8b, the shaft 8c of the solenoid 8b is activated, the lock of the protruding part of the cam 6 by the arm 8a is released, and the Accordingly, the free end side 5a of the lid 5 automatically rotates and stops until it is locked by the locking member 15.

Next, when a key on the keyboard 3 is operated, printing is performed on the fed paper A, and the printed paper A is ejected from the ejection port 11 along the inclined upper surface 5a of the lid body 5, and is printed on the electronic printer. The person operating the printer 1 operates the keys one after another while confirming the characters printed on the paper A supported by the top surface 5a, thereby enabling more accurate printing.

[Effects of this invention]

According to the present invention having the above configuration, the lid body automatically acts as a splice plate without attaching a splice plate or the like to the printer, thereby preventing the ejected paper from getting tangled, resulting in damage to the paper or damage to the printer. Malfunctions can be prevented, and since the ejected paper is supported by the lid that also serves as a splint and moves upwards, printing can be checked smoothly and printing can be done accurately on paper, among other benefits. play.
