Abstract

PURPOSE:To enable a paper feeding and delivery unit to be easily taken off and be attached by rotation by a method wherein the paper feeding and delivery unit is attached to a printer box body through a rotatable shaft and further, a groove capable of detaching and attaching the paper feeding and delivery unit is provided in a bearing part attached to the body. CONSTITUTION:A pair of shafts 1c are attached on the same axis to a rear part of a paper feeding and delivery unit 1, and a detent member 1d extends towards the end farther than the shaft parts. Further, grooves are formed vertically in guide bearings 2a for guiding the shafts 1c formed in the rear part of a printer box body 2 and further, detent parts 2d are provided together with the bearing in the front part of this bearing part 2a. The paper feeding and delivery unit 1 is moved in this groove direction to perform detaching and attaching. In a state wherein the paper feeding and delivery unit 1 is mounted on the printer body 2, a rotation detent member 1d is rotated by an angle 20 in contact with the detent member 2b, and an opening capable of mounting an automatic paper feeding and delivery unit 3 is secured. Further, the paper feeding and delivery unit 1 can be removed by rotating it by an angle 4 by which the detent member 1d and the detent member 2b do not interfere with each other in a direction wherein the groove of the guide bearing is formed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a printer housing structure.

[Conventional technology]

The main body of the conventional printer is used for single-sheet paper and continuous printing.

A metal or resin sheet kite is attached to guide the paper to the machine body, and an automatic paper feed/discharge device (hereinafter abbreviated as C8F) with an on-joy setting is attached to the housing body or the machine body. The housing structure was such that all of the guides for feeding and discharging paper and the cover 1 had to be removed when doing so.

　　　　　,.

[Problem to be solved by the invention]

In conventional technology, - In many cases, a sheet kite and multiple printer covers are attached independently to nine body parts as a standard or semi-standard condition, and all of these have to be removed when installing an automatic paper feed/eject device. There must be. It was also necessary to install a special cover for the automatic paper feed/discharge device. It was also difficult to store these parts. Furthermore, it was not easy to satisfy a unified design of the main body, the paper feed/delivery unit, and the automatic paper feed/delivery device.

Therefore, the present invention is intended to solve these problems, and its purpose is to automatically feed and eject paper, install a device,
At this time, the automatic paper feed/discharge device can be attached to the top of the printer housing by rotating the paper feed/discharge unit, which has the sheet guide, cover, and print cover fixed together, backwards around the shaft connected to the printer body. .

In addition, 1. The paper feed/discharge unit can be removed from the shaft to reduce the desk space occupied by the printer.

It is an object of the present invention to provide a printer casing structure that can increase the degree of design freedom when attaching a link body and an automatic paper feed/discharge device.

[Means to solve the problem]

The structure of the printer of the present invention includes a pair of bearings provided on the rear back surface of the printer casing, and a supply/discharge system mounted on the top surface of the casing via a pair of rotatable shafts corresponding to the bearings. In the housing structure of a printer having a paper unit, the bearing part has a kite groove, and further includes a locking member in front of the bearing part that locks the paper supply/discharge unit, and the paper is supplied/discharged from the housing body. It is characterized by the unit being removable.

〔Example〕 Embodiments of the present invention will be described below based on the drawings.

In Fig. 1, a printer cover 1a, a seat kite 1b
is connected to the paper feed/discharge unit 1 via a rotatable shaft (not shown).
installed on. A pair of axis ICs are coaxially attached to the rear of the paper feed/discharge unit 1. Further, a locking member 1d extends from the tip of the pair of shaft portions of the paper feed/discharge unit 1.

Furthermore, a kite bearing 2a is formed at the rear of the printer housing body 2 to guide the shaft IC. Further, as shown in FIG. 2, the guide bearing 2a has a groove formed in the vertical direction, and furthermore, a locking part 2b which is not formed integrally with the bearing is provided at the front part of the bearing part 2a. (FIG. 2) The paper feed/discharge unit 1 can be moved in the direction of this groove and can be attached and detached.

When the paper feed/discharge unit 1 is attached to the printer main body 2, as shown in FIG. It rotates to secure an opening where the automatic paper feed/discharge device 3 can be attached to the top surface of the printer. Next, paper feed/discharge unit 1
When removing the kite bearing, as shown in Fig. 2, remove it at an angle 4 such that the locking member 1d of the paper feed/discharge unit 1 and the locking member 2b of the printer main body side do not interfere in the direction in which the grooves of the kite bearing are formed. be able to. Further, at the angle of interference, the shaft IC is prevented from being removed.

Here, interference means that the rotational locking member 1d and the locking member 2
b, or a state where they collide.

FIGS. 3(a) and 3(b) are diagrams showing the state in which the paper feed/discharge unit 1 is rotated backward and locked. At this time, as shown in FIG. 2, members 1d and 2b are locked. The sheet feeding/discharging unit 1 is fixed by fitting together.

〔Effect of the invention〕

As explained above, the present invention attaches a paper feed/discharge unit and one printer housing main body via a rotatable shaft, and furthermore, a groove is provided in a bearing section attached to the main body to allow the paper feed/discharge unit to be attached and detached. Therefore, when installing the automatic paper feed/discharge device, the paper feed/discharge unit can be easily removed or rotated and installed.

Furthermore, even when the paper feed/discharge unit is removed, the design can be unified with the automatic paper feed/discharge device and the main body.
