In the conventional structure, for example, as shown in Japanese Utility Model Application Publication No. 50-153855, the zero axis of the totalizer provided in the speedometer display section passes through a transparent plate covering the scale number and the front surface. A knob is attached to the tip of the zero return shaft, which protrudes toward the driver, and the totalizer is returned to zero by pushing, pulling or rotating the knob.

However, in the conventional configuration described above, a rubber tube is attached to the zero return shaft in order to prevent chatter noise caused by the zero return shaft hitting the transparent plate due to vibration, etc., and to prevent dust from entering the case. ,
In order to ensure smooth movement of the zero return axis, it is necessary to provide a certain amount of play between the rubber tube and the transparent plate, which has the drawback that it is difficult to ensure good dustproof performance. Furthermore, since the zero return axis protrudes, there is a drawback that the zero return operation may be performed against one's will.

According to the above configuration, the zero return axis does not protrude from the transparent plate, and when necessary, the zero return axis is operated by inserting an operating member such as a key into the through hole of the transparent plate from the outside, so that the zero return axis cannot be operated by the driver. presses against one's will,
Children will not be able to manipulate the device by mischief.
This has the effect of being able to prevent erroneous operations. In addition, since a closing member that can be opened and closed is attached to the through hole in the transparent plate, the through hole in the transparent plate is always closed by the closing member except during the zero return operation, thereby preventing the above-mentioned penetration into the case. This has the excellent effect of reliably preventing dust from entering through the holes with a simple structure.

The present invention will be explained below based on the embodiments shown in the drawings. FIG. 1 shows an example in which the structure of the present invention is used in an operational recorder, where 1 is the recorder main body, a case 10 having a recording drive section (not shown), and a cover body having a recording paper, a clock 15, and a speedometer display section 14. 11 and 12
They are connected so that they can be opened and closed using the fulcrum, and are locked by operating the lock 8 with the key 9. 5
is a scale plate that displays speed and time, and a total totalizer 3 and a zero totalizer 2 are displayed from the display window. A speedometer pointer 13 is rotated by a drive unit (not shown) to display the vehicle speed, and a clock 15 in the center displays the time. Reference numeral 4 denotes a zero return axis having a groove 4a at its tip, and as shown in FIG. The height may be slightly lower than the scale plate 5). 7 is a transparent plate that covers the front surface of the scale plate 5;
A through hole 7a is provided at a position corresponding to the zero return axis 4, and a grommet 6 made of an elastic material such as rubber or vinyl chloride is fitted into this hole 7a. As shown in FIGS. 2 and 3, this grommet 6 has a groove 6b on its outer periphery for fitting into the hole 7a of the transparent plate 7, and a key 9 as an operating member is passed through the center of the grommet 6. It has a cross-shaped cut 6a that is normally closed.

Next, its operation will be explained. In the above configuration, when the totalizer does not need to return to zero, the speedometer,
The hands of the clock 15 etc. indicate normally without any trouble. Furthermore, the cutout 6a of the grommet 6 is closed to prevent dust and the like from entering the instrument. When returning to zero, insert the opening/closing key 9 of the cover 11 through the cut 6a of the grommet 6, fit the tip of the key 9 into the groove 4a of the zero return shaft 4, and press the key 9. Alternatively, by rotating it, the totalizer 2 can be returned to zero.

Note that the key 9 is not only a key for opening and closing the cover, but also a key for opening and closing the cover.
A similar key, such as a driver changeover key or a vehicle ignition key, may be used, as long as it is a key normally provided when the vehicle is in operation.
