Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recorder used, for example, in an underwater object detection device of 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 member, 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, the present 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 or set into the unwinding woodwind or the winding woodwind, or the recording paper can be removed from 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 edge of the paper between the back, front, and back 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.

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

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 end of the paper to the paper hanging roller 7 and belt 8.
It is necessary to take the paper through a complicated path such as bringing it out to the surface through the gap between the sheets, pulling it out onto the recording board 2, guiding it to the back side again through the gap between the paper feed roller 4 and presser roller 9, and winding it around the winding woodwind 11. Not only was this not an easy task to do on a ship, but it also caused meandering paper feed and poor winding.

In this invention, a feeding woodwind and a winding woodwind are arranged on the back side of a plane determined by a paper hanging roller and a paper feeding roller, and the recording paper, which is fed out from the feeding woodwind and on which a record is drawn at an appropriate position on the paper hanging roller side, is hung. In a recording device in which the recording paper is stretched and held between a roller and a paper feeding roller, and the paper feeding roller is rotated to sequentially move the recording paper and wind it onto a winding woodwind, the above-mentioned unwinding woodwind or winding woodwind is rolled from the top surface of the recording board. It is an object of the present invention to provide a recording device that can eliminate the above-mentioned disadvantages by movably holding the paper hanging roller and paper feeding roller so that they can be taken out or inserted and installed.

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 FIG. 3 or 4, the recording plate is composed of 55 and 56 made of approximately equal length, and one end of the recording plate 55 has a paper hanging roller 7, and one end of the recording plate 56 has a paper feeding roller 7. A roller 4 is rotatably attached. A hinge 57 is attached to the other end of the recording plate 55, and a holding fitting 40 for rotatably holding the payout woodwind 10 to which the recording paper 3 is attached is attached to the recording plate 55 so as to be positioned at a proper position on the back side. . Further, a handle 19 is attached to a suitable position on the recording plate 55. A holding fitting 40 for rotatably holding the winding woodwind 11 for winding the recording paper 3 is attached to the back surface of another recording plate 56, and a hinge attached to the recording plate 55 mentioned above is attached to the other end of the recording plate 56. 5
By attaching the other end of 7, the recording plate 5
5 and the recording plate 56 are bendably connected. Furthermore, fulcrums 58 and 59 are provided at appropriate positions on the back surfaces of the recording plates 55 and 56, respectively. The recording plate 55 is pivotally supported by a fulcrum shaft 60 that fits into the fulcrum 58, and is rotatably attached to predetermined positions of two side plates 12, 12 forming both sides of the frame of the recorder. The two side plates 12, 12 have an elongated hole 61 as shown in the figure, located at an appropriate distance from the mounting position of the fulcrum shaft 60.
61, and the recording plate 56 is mounted so as to be movable within the elongated hole 61 while being pivotally supported by a fulcrum shaft 62 that fits into the fulcrum 59. The paper feed roller 4 is rotated at a constant speed by a drive source (not shown), and the winding woodwind 11 is also driven at the same time.

The presser roller 9 has both ends connected to arms 26, 2.
6, and by the action of springs 27, 27 with appropriate tension, it is always in contact with the paper feed roller 4 while maintaining an appropriate contact pressure during the paper feeding state. A belt 8 to which a recording pen is fixed is stretched between two pulleys and rotated. Recording paper 3 is fed out woodwind 10
The sheet is unwound from the sheet, passes through the paper hanging roller 7, the surface of the recording plate, and the sheet feed roller 4, and is then wound onto the winding woodwind 11.

In Figure 3, when this recorder is operated,
The recording paper 3 fed out from the payout woodwind 10 has an underwater situation drawn with a recording pen, and then is sequentially fed by the action of the paper feeding roller 4 and the presser roller 9 and wound up on the winding woodwind 11.

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 55 and pull it up to release the hinge 57.
Due to the action of the elongated hole 61, the recording plate 56 is rotated as shown in FIG. 4, and the recording plate 56 is also raised at the same time. Therefore, as shown in the figure, the work of replacing the recording paper can be carried out extremely easily by simply operating the user's hand in the directions of the arrows L and L'. When the recording plate 55 is pushed down using the handle 19 after replacing the recording paper, the recording plate 56 is also pushed down at the same time, and the operation preparation state is set as shown in FIG.

As described above, according to the present invention, the recording paper 3 wound around the winding woodwind 11 located below the recording board and the feeding woodwind 10 are exposed by the action of simply pulling up the handle 19 when replacing the recording paper. A series of recording paper exchange operations such as removing used recording paper and inserting and installing unused recording paper into both wood pipes can be performed extremely easily.

In the above description, the recording plates 55 and 56 have been described as plate-shaped structures, but they are not limited to plate-shaped structures, and the same effect can be obtained with other shapes such as frame bodies or U-shaped structures. I can do it. Further, although the case has been described in which the handle 19 is attached to the recording plate 55, the handle 19 may be attached to the recording plate 56 depending on restrictions on the arrangement of surrounding structures. In that case, the fulcrum shaft 62 becomes a fixed position, and the other fulcrum shaft 60
A long hole 61 may be provided on the side.

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