Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table-embedded printing apparatus which is used in transactions of financial institutions such as banks and which is stored in a table and prints on a passbook, a slip, or a certificate. In particular, the present invention relates to a desk-bed embedded printing apparatus that has improved operability when replacing an ink ribbon or removing a jam.

2. Description of the Related Art Generally, among various OA devices, a printing device has a mechanical mechanism, so that a probability of occurrence of a failure is high. Particularly, a paper jam (jam) in a mechanism such as a paper feeding mechanism. Easy to cause. In some cases, when a paper jam occurs, a part of the transport path can be opened and closed in order to remove the jammed paper inside the printer.
For example, Japanese Patent Application Laid-Open No. 2-69273 describes a printing device in which the printing device is divided into upper and lower parts with a paper feed path as a boundary and the upper part can be opened and closed in order to easily remove jammed paper. ing. However, for a table-type embedded printer in which the printer itself cannot be opened or closed, that is, the printer itself is housed inside the table, the printer body must be placed inside the table when removing paper. The problem is how to expose it, and none was designed with due consideration of operability.

In a table-embedded printer, the printer body is once exposed from the inside so that the printer is exposed to the outside in order to remove jammed paper and replace the ink ribbon. Open the top of the table by providing a mechanism for taking it out or pulling it out and then pulling it out from the table, or by providing a mechanism for rotating and moving part of the table and the printer body with one point as a fulcrum. I was trying to create a space.

FIG. 5 shows the movable table 52 and the printer main body 5.
3 is a diagram showing the appearance when a slide rail type 3 is adopted and a method of pulling it out to the front side is adopted. This method does not cause much problem because the operation force is small, but since the printer main body is recessed, There is a problem that it is difficult to replace the ink ribbon and remove the jammed paper. FIG. 6 is an external view of a case in which the table movable unit 62 and the printing apparatus main body 63 are integrally rotated so that the printing apparatus main body is recessed as in the case of FIG. It is difficult to operate, and if the balance spring is not attached, it has the drawbacks that the movable part falls down toward you when it is pulled out, and the operating force when closing it is large.

[0005]

In recent years, in desk-top embedded printers such as those found in bank terminals, a page turning mechanism of a passbook, a page bar code reading mechanism, a printed line detecting mechanism, etc. Due to the increase in additional functions, the size of the device has been increased, and there is a demand for miniaturization of the table itself because it saves space, and as a result, instead of simply embedding the printing device inside the table, It has become necessary to incorporate it three-dimensionally. Specifically, it has become necessary to arrange the large-sized printing apparatus main body obliquely instead of horizontally. Here, in the extension of the above-mentioned conventional technique, there is a problem that the operability at the time of replacing the ink ribbon or removing the jammed paper is deteriorated due to the enlargement of the apparatus and the oblique arrangement. For example, the printer itself is heavy and cannot be taken out, or it requires a large amount of force to pull it out from the table. Even if it is pulled out, it is necessary to replace the ink ribbon or remove jams in the back of the table. There are various problems such as difficult work. The present invention solves the above-mentioned problems, and when exchanging an ink ribbon or removing a jam, the printing apparatus main body can be easily exposed from the inside of the table with a small force, and the table is embedded in the table. To provide a printing device.

[0006]

In order to achieve the above-mentioned object, the table-embedded printer according to the present invention divides the table into a table-fixed portion (1) and a table-movable portion (2), Movable table (2)
Is rotatably engaged with the table fixing part (1) at a fulcrum (2c) substantially below the printer main body (3), and the printer main body (3) near the print medium insertion port (3c). Characterized in that a cam sliding mechanism is provided between the table fixing part (1) and the vicinity of the printing mechanism part of the printer main body (3) so as to be rotatably engaged with the table moving part (2). There is. In addition, the cam sliding mechanism,
It is characterized in that it is composed of a cam portion (1a) provided on the table fixing portion (1) and a cam sliding roller (3a) provided on the printer main body (3). Furthermore, the shape of the cam portion (1a) provided on the table fixing portion (1) is substantially the same as the center of gravity of the table when the table movable portion (2) and the printer main body (3) are rotated. The feature is that it has a certain height.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a table-embedded printing apparatus is divided into a table-fixed portion, a table-movable portion, and a printer main body.
The table movable part is rotatably engaged with the table fixed part, the printer main body is rotatably engaged with the table movable part, and a cam is provided between the table fixed part and the printer main body. A sliding function is provided. In addition, the cam portion provided on the table fixing portion has a shape that reduces vertical movement of the center of gravity of the entire printer when the printer main body is pulled out.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a cross-sectional view of a table-embedded printer of this embodiment seen through from the side, and FIG. 2 is a diagram for explaining the operating state thereof, and FIGS. FIG. 3 is a perspective external view of FIG. 1 and FIG. 2. In this embodiment, the table is composed of a table fixed part 1 and a table movable part 2,
The printer main body 3 is built in. The printing apparatus main body 3 includes a medium insertion opening 3c, a transport roller group 3e, and a print head 3d, as a normal printing apparatus has, and a medium inserted from the medium insertion opening 3c by a known method. It is configured to be able to convey the sheet and perform predetermined printing. Although omitted in FIG. 1, a page turning mechanism such as a passbook, a page bar code reading mechanism, a magnetic stripe reading / writing mechanism, and a printed line detecting mechanism are arranged on the conveying path 3f of the printer body 3 as required. To be done.

In this embodiment, the table movable portion 2 is rotatable with respect to the table fixing portion 1 with the lower portion 2c of the printer body 3 as a fulcrum. The printing apparatus main body 3 is rotatably supported by the pedestal movable portion 2 at a fulcrum 2b near the medium insertion port 3c, and is provided with a cam sliding roller 3a near the printing mechanism portion to fix the table. It is in contact with a cam portion 1a provided on the portion 1. The shape 2 of the cam portion 1a will be described later. With this configuration, the following two effects are produced.

(1) When replacing the ink ribbon, or
When removing the jammed paper, it is necessary to open a space above the printer body and operate from there. In this embodiment,
Pull out the table movable part 2 toward the front around the fulcrum 2c. At this time, the printer main body 3 is pulled out by the engagement with the fulcrum 2b, but at the same time, the rear portion is lifted upward by the cam sliding roller 3a and the cam portion 1a. The movements of the center of gravity GD of the table movable part 2, the center of gravity GP of the main body of the printing apparatus, and the combined center of gravity G thereof are traced in FIGS. 1 and 2, respectively, GD1 → GD2, GP1 → GP2, G1 → G2, Although it moves to, it can be seen that there is no vertical movement of the composite center of gravity when moving from G1 to G2, because the movement is almost horizontal. In other words, when performing this operation, the height of the center of gravity does not change, so the operation force need only be friction, and it is stable even when the table movable part 2 is closed (Fig. 1) and opened (Fig. 2). It doesn't fall to either side. The shape of the cam portion 1a is formed so that the combined center of gravity (entire center of gravity) does not move up and down as much as possible when this operation is performed. It should be noted that by slightly changing the shapes of the start point and the end point of the cam portion so that the combined center of gravity becomes lower, it is possible to achieve two stabilization in the closed state and the open state. It goes without saying that various operation feelings can be easily obtained by combining balance springs and the like. The above is the first effect.

(2) Further, in the opened state, by the action of the cam mechanism including the cam portion 1a and the cam sliding roller 3a, the printer main body 3 (in particular, the portion inside the table fixing portion 1). However, as shown in FIGS. 2 and 4, since it is lifted and approaches the opening formed in the upper part of the table so as to be horizontal, the operability such as replacement of the ink ribbon and removal of jammed paper is improved. This is the second effect.

[0012]

According to the present invention, the printer body can be easily exposed from the inside of the table with a small force when replacing the ink ribbon or removing the jam with a simple structure.
It is possible to obtain a desk-bed embedded printing device with good operability.
