Description of the Related Art Conventionally, images from a personal computer, a camera-integrated video tape recorder, an electronic still camera, etc. have been soft-copied by a display device or the like capable of displaying high resolution. However, in recent years, a color printing device (video printer device) has been developed which is capable of displaying an image as a video image of these information sources as a full-color, high-definition hard copy.

Generally, a printing device such as a small printer device for a computer, a video printer device, a copying machine, etc., sequentially prints (prints) characters or the like in the digit direction (or the opposite direction) according to its printing method. ) Serial printers, (2) line printers that perform print processing for each line of print data, and (3) page printers that perform print processing for each page of print data It can be roughly divided into three types. In addition, each is divided into impact type that prints by mechanical impact force and non-impact type that does not have a hitting sound that uses heat or static electricity, and is further classified into a method according to the printing mechanism and the printing color method. To be done.

As described above, the present invention is mainly applied to a printing apparatus in a desktop printer (video printer apparatus) which is a non-impact type printing apparatus that does not generate a striking sound using heat or static electricity according to the classification. The present invention relates to a paper feed case for a printing device.

The video printer device is a color in which dyes of three colors, for example, yellow (Y), magenta (M), and cyan (C) are cyclically applied in a predetermined order in accordance with a video signal of an information source. A printing ink sheet (hereinafter abbreviated as an ink sheet) is circulated, and the Samar head is heated to sublimate the dye in the ink sheet to perform one-screen color printing on the recording paper (thermal transfer recording paper). There is. Further, this video printer controls the time width of the current applied to the samar head to adjust the amount of dye sublimated to perform gradation.

After recording by the above-mentioned method, the recording paper conveying mechanism of the printer device conveys the recorded recording paper, sends it out to the paper discharge case, and stores it. The recording phase of is completed.

Hereinafter, the structure of the paper feed case in the conventional video printer apparatus, which is one of the desktop line printers, will be described as an example. FIG. 4 is a diagram showing a paper feed case structure in a conventional printing apparatus (video printer apparatus). Further, FIG. 5 is a cross-sectional view of a conventional printing apparatus (video printer apparatus) showing a printing paper feeding and discharging mechanism.

In FIG. 4, the printing paper 1 is a paper feed case 2
Multiple sheets are stored in a stacked state. The paper feed case 2 is provided with a lid-like cover 3 to prevent the printing paper from coming out of the regular position after the printing paper is stored. This cover 3 has a widthwise dimension in the paper feed case 2.
It is formed to be smaller and is provided with an opening 2a for taking out the printing paper 1 by the paper feeding mechanism when it is attached to the paper feeding case 2. In such a state, the paper feed case 2 has the video printer device 4
3 The main body is loaded at the position indicated by the arrow X.

In most cases, the (discharged paper temporary storage space 10) is used for it. In the discharged paper temporary storage space 10 for receiving the discharged paper, the discharge paper temporary storage space 10 for receiving the discharged paper and the paper feed case 2 are partitioned from each other so that the discharged paper does not return to the paper feed case again. A paper receiving plate (paper discharging tray) 11 is installed for the purpose of. still,
The paper discharge tray 11 has an effect of preventing a paper jam generated when the discharged paper returns to the paper feed case again, and is configured to be removable.

However, according to the printer device having the above-mentioned configuration, the plate portion of the paper discharge tray 11 has a large member size (thickness), but its function is only to receive the discharged paper. The discharge paper temporary storage space 10, which is the upper part of the discharge tray 11, requires a predetermined height. Therefore, it has been an obstacle to making the printer thin and low in price. Therefore, in view of the arrangement, the paper feed cover 3 and the paper discharge tray 11 which are arranged at substantially the same position are partially used in common, and it is attempted to realize a thin type and a low price.

However, in the case of the above method, the paper feed case cover 3 is a cheap component which is forgotten to be attached, and the paper discharge tray 1
Since 1 is also used as the paper feed case cover 3, if the paper feed case cover 3 is forgotten to be attached, the ejected paper returns to the paper feed case again (to an irregular position), and However, there is a problem that the next paper to be supplied is not normally supplied or the next paper to be discharged (paper discharge) is obstructed to cause a paper jam (jam).
Furthermore, even if the paper feed case cover 3 is correctly attached, the ejected paper is provided with the opening 2 provided in the paper feed case 2.
There is a problem that the paper is again returned to the paper feed case from a and paper jam occurs in the same manner.

[0014]

As described above, it is necessary to effectively use the limited space in the desk-top type printing apparatus as described above. Therefore, in terms of the layout, the paper feed cover and the paper discharge tray, which are arranged at almost the same position, are partially used as one part, and it is attempted to realize a thin type and a low price. However, as a matter of experience, the paper feed case cover 3 is a cheap part that is forgotten to be attached. Therefore, according to such a method, when the paper feed case cover 3 is forgotten to be attached, since the paper discharge tray 11 shares the paper feed case cover 3, the discharged paper is placed on the paper feed case again. Returning to (non-regular position), this paper (paper ejection) becomes an obstacle and the next paper to be fed is not fed normally, or the next paper to be ejected (paper ejection) is obstructed and a paper jam occurs. There was a problem (defect) of causing (jam). Further, even if the paper feed case cover 3 is properly attached, there is a problem that the ejected paper returns to the paper feed case from the opening 2a provided in the paper feed case 2 and causes a paper jam. .

Therefore, the present invention has been made in view of such a problem,
An object of the present invention is to provide a printing device and a paper feeding case for the printing device, which can share the parts, that is, can share the paper ejection tray and the paper feeding case cover while avoiding the problem of paper jam. Is.
