BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording pen lifting device.

[0002]

2. Description of the Related Art A recording pen lifting / lowering device used in a pen recorder or the like is, as shown in FIG.
, A prismatic rod 22 having a right end connected to the upper end, and an upper plate 23.
And a U-shaped holding member 25 for inserting the rod 22 into square holes formed in the lower plate 24 and holding the rod 22 upright, and a spring 26 for urging the rod 22 upward.
The recording pen 1 is moved up and down as follows. That is, after the rod 22 is pushed down, the rod 22 is rotated at an angle of 45 °
2 is fixed to the back surface of the square hole of the upper plate 23 by the pressing force of the spring 26.
, The lever 21 moves downward in parallel, and the recording pen 1 descends on the recording paper. On the other hand, when the rod 22 is rotated in the opposite direction by an angle of 45 ° about its axis, the locking surface 22a is disengaged from the square hole of the upper plate 23, and the rod 22 moves upward by the restoring force of the spring 26. ,
Following the rod 22, the lever 21 translates upward,
Accompanying this, the recording pen 1 is raised. A stopper 27 prevents the rod 22 from rotating beyond a predetermined angle.

[0003]

However, in such a conventional recording pen lifting device, the recording pen 1
When the rod 22 is moved up and down, the height of the rod 22 is increased due to the vertical movement of the rod 22 (that is, the depth of the recording apparatus is increased). Installation of the device becomes difficult. If the rod 22 is accidentally removed during the operation of the elevating device, the recording pen 1 is vibrated in the vertical direction, so that the recording pen 1 is damaged or a large amount of ink is ejected and the recording paper 1 is ejected. There is a fear of soiling.

The present invention has been proposed in view of such circumstances, and provides a recording pen lifting / lowering device that reduces the height of the recording device, reduces the depth of the recording device, and stably raises / lowers the recording pen. I do.

[0005]

According to the present invention, the recording pen is vertically supported by vertically supporting the recording pen, and the recording pen is raised and lowered by a quarter turn in the forward and reverse directions via a handle. A horizontal strip-shaped movable support plate having an eccentric pivot for changing the height thereof, a stopper piece and a handle piece protruding in the left and right direction on the left and right of one end in the longitudinal direction of the movable support plate, and the movable support plate. A pair of front and rear bearings that hold horizontally and rotatably support a pair of eccentric pivots coaxially protruded at both ends thereof, between the other end in the longitudinal direction of the movable support plate and the eccentric pivots. A spring, which is interposed and urges the movable support plate toward the one end, and a rear bearing which supports an eccentric pivot at one end of the movable support plate, is engaged with the stopper piece to allow the movable support plate to be engaged. Place the board in the horizontal position before turning over. The standing posture is upright inverted after moving axially abolish engaged by the elastic force of the spring
And a locking portion .

[0006]

According to this configuration, after the support plate is moved through the operation piece against the resilience of the resilient member and then rotated to a predetermined angle, the support plate is moved to a predetermined position by the stop mechanism. Is fixed in the stopped state. On the other hand, the recording pen rises away from the recording paper following the inversion of the support plate. When the support plate is inverted by the restoring force of the resilient member after the support plate is reversed in the opposite direction via the operation piece, the support plate is fixed in a predetermined stop state by the stop mechanism. On the other hand, the recording pen descends onto the recording paper following the reversal of the support plate.

FIG. 1 is a plan view, FIG. 2 is an overall perspective view showing a support plate of FIG. 1, and FIG. 3 is a partially enlarged view showing a part III in FIG. It is. 4, the same reference numerals as in FIG. 4 denote the same members as in FIG. 4, and the structure of the present invention is significantly different from that in FIG. The mold support plate 1 is provided. That is, 2 is a support plate made of a strip-shaped thin plate that is long in the horizontal direction,
At the front and rear ends, a front shaft 3a and a rear shaft 3b in the front-rear direction for supporting the tip of the recording pen 1 in the vertical direction are eccentrically protruded on the same axis, and the shafts 3a and 3b are front and rear bearings 4 respectively.
It is rotatably supported by a rear bearing 5. Support plate 2
A spring 6 is mounted between the front shaft 3a and the front bearing 4 in the longitudinal direction, and the support plate 2 is urged in the axial direction (rearward ) toward the rear bearing 5 by the elastic force of the spring 6. And
As shown in FIG. 2, a stopper 7 protruding rightward on one side and a handle 8 protruding leftward on the other side are provided at the rear end of the support plate 2, respectively. As shown in the figure, a horizontal base 9 formed integrally with the rear bearing 5
Front notch 13 of the horizontal locking portion 10
The vertical locking portion 11 facing rightward with the end face 12f is a plan view.
By forming a vertical plane that forms an L-shaped notch,
A stop mechanism for the support plate 2 in a horizontal to vertical position.
ing. That is, in the horizontal state before the support plate 2 is inverted, as shown in FIG. 3, the stopper 7 and the handle 8 abut against and lock the horizontal locking portions 10 corresponding to the upper surface of the base 9, respectively. support plate 2 by pressing against the elastic force to the rear of the spring 6 only the δ the handle 8 in the direction of the front bearing 4
When the stopper 7 is moved away from the locking portion 10 and then turned 90 ° in the direction of the arrow in the figure, the stopper 7 comes into contact with the vertical locking portion 11 and stops, and the elastic force of the spring 6 is released. As a result, it is pressed against the front end face 12f and fixed in the upright posture. After the support plate 2 is slightly moved in the axial direction via the handle 8 as described above, the support plate 2 is supported upright around its axis by reversing 90 °. Rise away from above. Further, in the upright state, after the support plate 2 is reversed and leveled through the handle 8 to the original position by the restoring force of the spring 6, the recording pen 1 is driven by this to move it back. It is supported on the horizontal surface of the support plate 2 and descends onto the recording paper 15 (FIG. 1).

[0008]

According to such a structure, the support plate 2 is not moved in the vertical direction, but is inverted by 90 ° in the forward direction and the reverse direction, so that the support plate 2 stands up or down around the axis. Since the recording pen 1 is moved up and down while lying down, the height of the elevating device is reduced, and as a result, the pen recorder can be made thinner. The reversal of the support plate 2 is based solely on human operation, and the resilience of the spring 6 is not involved in this. Therefore, the operator accidentally removes the handle 8 from the hand during the operation of moving the recording pen 1 up and down. However, the recording pen 1 can be stably moved up and down without giving any vibration in the vertical direction. In short, according to the present invention, an eccentric pivot that vertically supports the recording pen in a vertical position and rotates the recording pen up and down by a quarter turn in the forward and reverse directions via a handle to change its height. A horizontal strip-shaped movable support plate having: a stopper piece and a handle piece protruding in the left-right direction on the left and right ends of one end in the longitudinal direction of the movable support plate, and holding the movable support plate horizontally and at both ends thereof A pair of front and rear bearings rotatably supporting a pair of eccentric pivots protruded coaxially and interposed between the other end in the longitudinal direction of the movable support plate and the eccentric pivot; A spring that biases the movable support plate toward the one end, and a rear bearing that supports an eccentric pivot at one end of the movable support plate. And then flip after moving in the axial direction The resilient force of the spring in the standing has been standing posture Te
By providing a locking portion for locking more , the height dimension is shortened, the depth dimension of the recording apparatus is reduced, and a recording pen lifting / lowering device that stably raises / lowers the recording pen is obtained. It is extremely useful in industry.
