[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer having a feature in an assembly portion of a printing mechanism and a paper feeding mechanism.

[0002]

2. Description of the Related Art In a serial printer which performs recording and writing by moving a head in a main scanning direction, a long part such as a platen, a carriage guide, or a sheet guide is temporarily assembled between left and right side frames, and these side parts are mounted. An assembling method, which is called "yagra assembly", in which the frame is fixed and integrated on both sides of the main frame, is adopted.

However, among printers of this type, in particular, a printer in which a paper feed cassette is mounted on the lower surface of the main body must have a slanted paper feed path so that the paper feed side is higher. Then, after assembling the long parts, when assembling the movable parts for printing and paper feeding, all of these must be assembled diagonally to the main frame, which is extremely troublesome. Not only was there a lot of obstacles to automation.

[0004]

[Problem to be solved by the present invention] The present invention has been made in view of such a problem.
It is an object of the present invention to provide a new printer in which a group of movable members can be easily inclined and assembled to a main body frame by using a frame different from the main body frame.

[0005]

That is, the present invention [SUMMARY OF] as a printer for accomplishing the above problems, assembling the print mechanism and paper feed mechanism to the base frame relative to the lower surface
And bent at the front and rear ends of the base frame according to the angle of the base frame to be attached at an angle.
To form a downward mounting piece and an upward mounting piece
On the other hand, this base frame
Corresponds to each of the downward and upward mounting pieces
Where the upper and lower mounting points are formed.
And fix the mounting piece to each corresponding mounting part
This allows the base frame to be integrated with the body frame
It is intended to be attached .

Embodiments of the present invention will be described below. FIG. 1 is an exploded view of a serial printer according to an embodiment of the present invention, and FIG. 2 is an exploded view of a main part thereof. The base frame denoted by reference numeral 1 in the drawing is configured separately from the main body frame 30 as a frame incorporating a group of movable parts for printing and paper feeding.

FIG. 2 shows an embodiment of the base frame 1. The base frame 1 is configured so that recording and writing can be performed on both cut sheets and continuous tone sheets. The base frame 1 is provided at the center thereof with a slit 2 through which cut sheets can be pulled out from a sheet cassette 5 (FIG. 3) loaded below.
The first half is mainly configured as an assembly area of the printing mechanism, and the second half is configured as an assembly area of the paper feed mechanism.

The base frame 1 has, on both sides thereof,
Platen 11, paper feed roller 12, carriage guide 1
3. Left and right side frames 15, 20 for supporting a long member such as the paper guide plate 14 are attached. One of these side frames 15 is provided at its lower end with a pulley shaft support 16 parallel to the base frame 1 so that a belt pulley 17 and a ribbon drive shaft 18 can be fitted therein. A drive motor 21 for driving a paper feed mechanism such as the platen 11 via a wheel train is attached to the other side frame 20. Further, on the outside of the side frame 20, a carriage driving motor 22 is mounted so that its axis is perpendicular to the surface of the base frame 1 and the bracket 23 and the belt pulley 2
4 is attached.

On the other hand, a carriage 26 for supporting the print head 25 is slidably mounted on the carriage guide 13 so that the surface thereof is parallel to the base frame 1, and is mounted on belt pulleys 17 and 24. The timing belt 27 is connected.

By the way, the base frame 1, which carries a group of movable members for printing and paper feeding, has
At the front end sides and the rear end sides, mounting pieces 3, 3, and 4 having a downward inclination angle and an upward inclination angle corresponding to the mounting angle θ (FIG. 3) of the base frame 1 are provided. Are fixed to bolts 33... On upper mounting portions 31, 31 formed on both sides of the front end and lower mounting portions 32 provided on the bottom surface on both sides of the center.

Reference numeral 28 in the drawing denotes a ribbon cassette, 2
Reference numeral 9 denotes a pull tractor which is detachably mounted above the rear portions of the side frames 15 and 20, reference numeral 34 denotes a circuit board which is mounted on the main body frame 30, reference numeral 40 denotes a cover main body which covers the main body frame 20, and reference numeral 41 denotes a front surface thereof. Each panel to be mounted is shown.

Next, the process of assembling the printer constructed as described above will be described.
Left and right guide frames 1 on which long objects such as a paper feed roller 12, a carriage guide 13, and a paper guide plate 14 are attached.
5 and 20 are fixed to both sides of the base frame 1. Next, the base frame 1 is supported by a jig so as to be parallel to the surface of the conveyor, and in this state, the belt pulley 17 and the ribbon drive shaft 18 are vertically dropped into the pulley shaft support 16 of one side frame 15, and On the outside of the side frame 20, a carriage driving motor 22 is fixed on the base frame 1 via a bracket 23 together with a belt pulley 24. Further, on a carriage 26 held horizontally by the carriage guide 13, Print head 2
5 is mounted perpendicular to the surface of the base frame 1.

When a group of printing mechanisms and paper feed mechanisms are mounted on the base frame 1 in this manner, the base frame 1 is finally provided with mounting pieces 3, which are bent at both front and rear ends thereof. 3, 4, and 4
Abut the high and low mounting portions 31 and 32 provided on both sides of the front end and the central portion of the central portion.
3 to fix integrally. As a result, the base frame 1 and a group of printing mechanisms and paper feeding mechanisms carried thereon are mounted at a predetermined angle on the main body frame 30 as shown in FIG. When the case body 40 is covered, the printer is completely assembled .

[0014]

As described above, according to the present invention, a printing mechanism and a paper feeding mechanism are mounted on a base frame on the basis of the lower surface, and the front and rear ends of the base frame are adjusted to the mounting inclination angle. The lower and upper mounting pieces are bent and fixed to the higher and lower mounting parts provided in the corresponding parts of the body frame. It is possible to accurately assemble the components on the main body frame with a given group of components having a predetermined angle.

Further, after assembling the printing mechanism and the paper feeding mechanism, if the base frame is dropped into a required position on the main body frame, each of these mounting pieces can be attached to the corresponding high and low mounting parts on the main body frame. The base frame can be easily mounted on the main body frame at a required angle by simply fixing them with bolts or the like.
