Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recorder used in an underwater object detection device such as a fish finder. In these recorders, a feeding woodwind and a winding woodwind are arranged on the back side of a plane determined by a paper hanging part, for example, a paper hanging roller and a paper feeding roller, and a record is drawn at an appropriate place on the paper hanging roller side as it is fed out from the feeding woodwind. The recording paper is stretched and held between a paper hanging roller and a paper feeding roller, and the paper feeding roller is rotated to sequentially move the recording paper and wind it up on a winding woodwind. In particular, this invention allows the unwinding woodwind or the winding woodwind to be taken out or inserted into the recording observation side, and therefore the recording paper can be inserted into or set into the winding woodwind or the winding woodwind, or the recording paper can be inserted into the winding woodwind. The present invention relates to a recorder that can be easily removed.

Many underwater object detection devices use a method that receives reflected ultrasonic waves and records continuous underwater cross-sectional images on recording paper, but the recording paper is automatically re-rolled after recording. Many have mechanisms. Generally, in this type of recorder, the recording paper is stretched over almost the entire surface of the recorder, as shown in Figure 1, in order to make it possible to observe the underwater cross-sectional image drawn on the paper over as wide a range as possible. , it is customary to store the wound woodwind on the back side. Therefore, both unused recording paper and recorded recording paper are stored on the back side of the recorder, so when replacing the recorder, raise the recorder and fold the edges of the paper into the back, front, and rear sides. It had to be rotated around the ship, which was troublesome and required some skill, especially when replacing it on a shaky ship.

FIG. 1 shows a perspective view of a conventional apparatus, and FIG. 2 shows an explanatory view of a cross section of the recorder shown in FIG. 1, viewed from the direction of arrow A.

In FIG. 1 or 2, an unused recording paper 1 is fed out to the back side of a recording plate 2 and rotatably supported by a woodwind 10, and the leading edge of the recording paper 3 is fed through the surface of the recording plate 2 as shown in the figure. It is fed out at a constant speed by a roller 4, and then wound onto a winding woodwind 11 again on the back side of the recording plate 2.

In this case, as described above, the recorded underwater image is designed to be displayed as widely as possible, so both the unused recording paper 1 and the winding woodwind 11 are stored on the back side of the recording plate 2 and cannot be seen from the direction of arrow B. It is normal not to have one. Therefore, when replacing the recording paper, raise the entire recording device 6 and insert the new recording paper 1 from the back side.
Attach the paper, bring the leading edge of the paper out through the gap between the paper hanging roller 7 and the belt 8, and pull it out onto the recording plate 2.
It is necessary to guide the paper through the gap between the paper feed roller 4 and the presser roller 9 to the back side again and wind it around the winding wood pipe 11, which is not an easy task on a ship that is moving, but also makes it difficult to feed the paper. This caused meandering and winding problems.

This invention provides a recorder that can eliminate the above-mentioned problems by moving only the recording plate so that the above-mentioned unwinding woodwind or wound-up woodwind can be taken out or inserted and installed from the recording observation side. It is.

FIG. 3 is an explanatory diagram of one embodiment of the present invention, and FIG. 4 is an explanatory diagram showing the state of the embodiment shown in FIG. 3 when the recording paper is replaced.

In FIGS. 3 and 4, an arm 36 is rotatably supported around the center of the winding woodwind 11 by a gear 35 fixed to the side plate 12 concentrically with the winding woodwind 11. A pivotally supported gear 37 meshes with the arm 36, and a gear 38, which will be described later, is rotatably supported on the other end of the arm 36 and meshes with the gear 37.

The above-mentioned gear 38 is fixed concentrically with the paper feed roller 4 on the side surface of a recording plate 39, which has a paper hanging roller 7 rotatably attached to one end and a paper feed roller 4 rotatably attached to the other end. Further, on the back side of the recording plate 39, an unused recording paper 1 is placed on a feeding wood pipe 10 which is rotatably held by a holding fitting 40.

When recording using this recording device, as shown in FIG. 3, the paper feed roller 4 comes into contact with the presser roller 9, which is rotated at a constant speed by a drive source (not shown), so that the recording paper 3 is fed out at a constant speed. , and wind it up on the winding woodwind 11. Further, instead of rotating the presser roller 9, it is also possible to rotate the paper feed roller 4 and bring the presser roller 9 into contact with it.

When you finish using the unused recording paper 1 after a long period of use and want to replace the recording paper, hold the handle 19 provided on the recording plate 39 and pull it up.
9 rotates about the center of the gear 38, that is, the paper feed roller shaft as a fulcrum. At this time, the gear 37 meshing with the gear 38 tries to rotate in the direction of the arrow as shown in FIG. Rotate it to the right. Since the paper feed roller 4 is supported at the tip of the arm 36,
1 installed in the unwinding woodwind 10 by this movement.
Both the recording paper 5 wound up on the winding woodwind 11 are exposed. Therefore, as shown in the figure, the recording paper replacement work can be carried out extremely easily by simply operating the user's hand in the directions of arrows G and G'.

Once a new recording sheet has been installed, the state shown in FIG. 3 can be restored by simply pushing the handle 19 and folding down the recording board, and no skill is required at all.

As described above, according to the present invention, when replacing the recording paper, the paper hanging roller and the paper feeding roller are moved by one action of moving the handle provided at the appropriate position in a predetermined direction, and the recording paper is fed out into the woodwind or unused. It is possible to provide a recording device that exposes the recording paper, the wound woodwind, or the recorded recording paper, and allows insertion and installation of unused recording paper or removal of used recording paper with great ease.

In the above embodiment, the recording plate 39 has been described as a plate-like structure, but it is not limited to a plate-like structure, and the same effect can be obtained with other shapes such as a frame or a U-shape. Can be done.

Incidentally, instead of the paper hanging roller 7 in the above embodiment, it is also possible to use a flat plate suitably bent to have a curved surface.
