Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an XY recorder such as an XY plotter. To be more specific, drawing is performed using multiple pens, and multiple recording pens are stored in a fixed holder at the end of the device, and the pen holder is made to select from among these multiple pens. ,
This invention relates to an XY recorder that automatically holds any recording pen in a pen holder to draw a diagram.

Conventional structure and its problems Conventionally, as shown in FIG.
The pen 16 is attached and detached by operating the arm 15 and the like, which has the disadvantage of a complicated structure and increased cost.

Furthermore, as shown in FIG. 2, the fixed holder part 21 and the pen holder part 22 are provided with magnets 23 and 24, respectively, and it is also necessary to have a magnetic material part 25 in a part of the pen body in order to be attracted by the magnet. As a result, the load on the holder increases and the pen tip wears out more quickly.

Purpose of the Invention In order to eliminate the above-mentioned drawbacks, the present invention provides a pen holder and a fixed holder for replacing a recording pen.
The purpose is to have a simple structure, be lightweight, have reliable pen exchange operation, and reduce costs.

Structure of the Invention In order to achieve the above-mentioned object, the present invention has a pen holder part and a fixed holder part each composed of an integral molded product made of synthetic resin that is lightweight and has a simple shape, so that pen replacement can be performed reliably. In addition to having a devised shape, it is equipped with guide protrusions that allow the recording pen to be positioned accurately, and the elasticity of the synthetic resin is used to facilitate replacement of the recording pen. There are few parts that can cause instability in operation, and since it is a molded product, the appearance is easy to maintain, and it is designed to prevent the recording paper from floating up from a part of the fixed holder and coming into contact with the pen tip. It is an object of the present invention to provide a recording pen holding device for an XY recorder which has high cost performance and also has a paper holding part.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be explained below based on the drawings.
This is a diagram showing the external appearance of the recorder, where 30 is the main body of the X-Y plotter, 40 is a plurality of fixed holders for storing pens, and 32 is the Y-axis carriage of the X-Y plotter, which moves in the X direction of the drawing. . A movable pen holder 33 is attached to the Y-axis carriage 32 and is movable in the Y direction in the drawing. 50 is a frame to which the fixed holder part 40 is attached, and 60 is a recording pen housed in the fixed holder part 40, respectively. Next, as shown in FIGS. 4 to 6, the fixed holder part 40
The relationship between the frame 50 and the recording pen 60 will be explained in detail. First, FIG. 4 is a perspective view of the fixed holder section 40, and FIG. 5 shows that the fixed holder section 40 is connected to the frame 50.
It is a figure which is attached to and holds the recording pen 60.

41 is an arm portion that holds the recording pen shown in Fig. 6;
The recording pen 60 is designed to enter from the direction of the arrow shown in FIG. Here, the inner diameter of the arm portion 41 is set to be equal to the diameter of the portion 63 of the recording pen 60, and 43 is a protrusion provided at the tip of the arm portion 41 to prevent the recording pen 60 from slipping out. I'm hugging you.

42 and 48 are guide protrusions that engage with grooves 61 and 62 provided in the recording pen 60.

Reference numerals 65 and 66 are semicircular bulges at the ends of the protrusions 42 and 48 on the arm 41 side, and the recording pen 60 is held at a position corresponding to this portion. ing.

Therefore, the recording pen 60 is held under pressure by the fixed holder portion 40 in both the vertical and horizontal directions.

45 and 46 connect the fixed holder part 40 to the frame 50
These are bosses for mounting on holes 51 and 52, respectively.
The fixed holder part 40 is fitted into the frame 5.
Fixed to 0.

Reference numeral 44 denotes a papilla-shaped protrusion, and the bosses 45 and 46 can be easily fitted into the holes 51 and 52 provided in the frame 50 by bending a portion 47 connected thereto.

Since the protrusion 44 is located below the pen tip 64, it holds down the recording paper 53 and prevents the pen tip 64 from contacting the recording paper 53 and staining the surface of the recording paper.

Next, as shown in FIGS. 7 and 8, the movable pen holder 33
The relationship between the recording pen 60 and the recording pen 60 will be explained in detail. FIG. 7 shows the movable pen holder 33, and FIG. 8 shows the movable pen holder 3.
3 is a diagram showing a recording pen 60 being held.

The claws 71 and 72 that hold the recording pen 60 are
Each has a locking portion 75, 76 at its tip.

In order to hold the recording pen 60 in the movable pen holder 33, the recording pen 60 is advanced from the direction of the arrow in FIG. At this time, the locking parts 75 and 7
When passing through 6, the claws 71 and 7 are removed by the amount of protrusion.
2 opens, but when it moves further inward past the locking parts 75 and 76 and reaches the point where the grooves 61 and 62 touch the curved parts 77 and 78, the recording pen 60 stops. Then, it is held by the spring force caused by the deflection of the claws 71 and 72.

Therefore, the recording pen 60 is always held at a fixed position under pressure by the locking parts 75 and 76 and the curved parts 77 and 78.

In this way, since the recording pen 60 is held in two places, the upper and lower positions, it is very stable, and the recording pen 60 can be made to move in accordance with the movement of the pen holder 33. Note that 73 and 74 are protruding pieces provided with curved parts 77 and 78, and the claws 7
He is facing 1,72.

FIG. 9 shows a fixed holder 40 and a movable pen holder 33.
FIG. 3 shows the recording pen 60 being held in each other's arms.

Next, the operation of holding a recording pen in the above configuration will be explained with reference to FIG. 3
If you are trying to attach it to pen holder 33,
enter from the direction of ◯A, stop at the position shown in the figure, and hold the recording pen 60 together. After that, as you move in the direction of ○○, the protrusion 43 at the tip of the arm 41 opens,
The recording pen 60 is moved to the movable pen holder 33.

Conversely, if you want to move the recording pen 60 from the state in which the movable pen holder 33 is holding the recording pen 60 to the fixed holder 40, the pen holder 33 enters from the direction of ○C and moves to the same position as shown above. They stop at the position and hold the recording pen 60 together in the same way as above. After that, when moving in the direction of ○D, click the tabs 71 and 72.
The locking parts 75 and 76 at the tip of the recording pen 6 are opened.
0 will be held by the fixed holder 40. Note that the movable pen holder 33 moves in various directions by relative movement with the Y-axis carriage 32, but since this is not the main focus of the present invention, a description thereof will be omitted.

Effects of the Invention As is clear from the above embodiments, the present invention has a structure in which a fixed holder is provided with an arm portion that holds a recording pen, a protrusion that engages with a groove, and a boss that engages with a hole in a frame. Therefore, reliability can be improved with a simple shape, and even if only the fixed holder part is damaged, only the corresponding fixed holder part needs to be replaced, so the overall cost is extremely low.

In addition, since the pen holder part and the fixed holder part of the present invention are each made of lightweight and simple-shaped synthetic resin integrally molded parts, the overall elasticity of the synthetic resin is utilized to make the recording pen It can be replaced and has excellent effects in terms of reliability, appearance, and paper retention.
