Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording pen holding mechanism of a recorder for recording measured values while a recording pen moves on a recording paper surface.

[0002]

2. Description of the Related Art In a recording meter, a large number of recording pens are arranged, and a recording means provided with a recording pen for drawing and recording a measured value on the recording paper while traveling while being pressed against the conveyed recording paper is widely used. . For example, the recording pen 1 in the recording meter as shown in FIG. 5 is fixed to the ink supply unit 2. The ink supply unit 2 is placed on a movable pen holder 3, and in the axial support portion of the overhanging piece 3a of the pen holder 3, a horizontal rod 7 such as a beam member installed on the recorder main body is arranged in the width direction of the recording paper. Fixed shaft 6 of pen holder base 6 slidably loosely fitted
It is fitted to a. The fixed shaft 6a and the projecting piece 3a are fixed to each other by an adjusting collar 5 and a retaining ring 11 at the shaft supporting portion thereof, and the adjusting collar 5 is adjusted in position in the width direction by an adjusting screw 4 and the like. Is attached to the fixed shaft 6a. Since the gap between the recording pen holding base and the pen holder base that is the moving member causes lateral vibrations and the like and greatly affects the recording accuracy, it has been desired to minimize the gap between the two. Conventionally, this position accuracy is performed by the adjusting collar 5 and the adjusting screw 4, but since this position adjustment is performed in a very narrow place, it takes a long time for adjustment, and an operation work such as requiring a special tool is required. Was very troublesome.

[0003]

In the conventional recording pen holding mechanism, it is necessary to operate the adjusting screw 4 to adjust the gap between the pen holder and the pen holder base, and this adjusting work is troublesome. An object of the present invention is to provide a recording pen holding mechanism having a simple structure that does not require a collar for adjusting the rotation axis of the pen holder base when adjusting the gap between the pen holder base and the pen holder that prevents the recording pen from rolling. is there.
A second object of the present invention is to provide a recording pen holding mechanism capable of holding the pen holder of the recording pen at a predetermined position when replacing the recording pen.

[0004]

The above object of the present invention can be achieved by the following constitution. The configuration is such that a recording pen that draws and records by press-contacting the surface of the recording paper, an ink supply unit that is fixed to the recording pen and that has an ink supply member that supplies ink to the recording pen, and an ink supply unit. A pen holder that movably supports in the pressing direction of the recording paper surface, a pen holder rotatably supported on a fixed shaft and movably in the width direction of the recording paper, and a pen holder base loosely fitted on a horizontal rod installed on the main body, and the pen holder An adjusting spring is arranged at a position that regulates the lateral movement in the recording paper width direction, and the adjusting spring biases the pen holder so that the tip of the recording pen presses the recording paper surface. The configuration is such that recording is performed while pressing against the recording paper surface.

[0005]

In the recording pen holding mechanism of the present invention, the recording pen is rotatably supported on the fixed shaft. For example, by using a coil spring, the recording pen tip is pressed against the recording paper surface at a constant pressure by the pressing spring. Not only is the recorded state clear, but the spring member also has a positioning mechanism that presses against one side of the pen holder base.
There is no need for complicated adjustment work for adjusting the gap between the pen holder and the pen holder stand, such as adjusting collars and adjusting screws, unlike the conventional case. Also, up the recording pen (UP)
The setting can be done by fitting the pen holder fitting hole into the pen holder stand projection and holding it at a predetermined position. Therefore, the recording pen can be held in the up (UP) state by a simple method of lifting the recording pen holder portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a recording pen holding mechanism of the present invention is shown in the drawings. FIG. 1 is an exploded perspective view of an embodiment of a recording pen holding mechanism of the present invention. FIG. 2 is a plan view of FIG. FIG. 3A is a partial cross-sectional side view showing a drawing recording state of the recording pen holding mechanism. FIG. 3B is a partial cross-sectional side view when the recording pen of the recording pen holding mechanism is retracted from the recording unit. FIG. 4 is a perspective view of a recorder equipped with the recording pen holding mechanism of the present invention. FIG. 5 is a plan view of a conventional recording pen holding mechanism.

A recording pen holding mechanism of the present invention will be described based on an embodiment shown in the drawings. The ink supply unit 2 to which the recording pen 1 is fixed is placed on the pen holder 3. On the fixed shaft 6a provided on the pen holder base 6 movably fitted to the horizontal rod 7, the protruding pieces 3a, 3 of the pen holder 3 are attached.
b is pivotally supported. The protruding piece 3a of the pen holder 3,
A coil spring 8 is provided so as to be urged to one side between 3b and press one protruding piece 3a toward the fixed shaft 6a side of the pen holder base 6. One end thereof is hung on the pen holder base 6, and the other end is hung on the back surface of the pen holder 3. As a result, the pen holder 3 is biased in the direction in which the recording pen 1 is pressed against the recording paper.

Further, the overhanging piece 3a of the pen holder 3
A fitting hole 9 is formed at a position where it engages with a projection 10 provided on the inner surface of the pen holder base 6, and this is a positioning mechanism for locking the pen holder 3 at a predetermined position. Figure 2
As shown in FIG. 3, this positioning mechanism is provided close to the shaft support (fixed shaft 6a) of the overhanging piece 3a provided at the end of the pen holder 3, and holds the recording pen 1 at a predetermined position when lifted.

[0009]

According to the recording pen holding mechanism of the present invention, the elastic member is arranged between the pen holder base and the pen holder to constantly press the recording pen in the recording paper surface direction. The recording is reliably performed, the position is regulated to one side by being urged by the elastic member, and the recording pen can be held by a simple mechanism without requiring an adjusting screw for adjusting the gap between the pen holder and the pen holder base. it can. Moreover, since the holding portion can be easily lifted and held at a predetermined position when the recording paper is replaced, the replacement work and maintenance can be easily performed.
