Abstract

PURPOSE:To improve the visual readability by providing a light shielding cover, with which the gap between display wheels is covered, between display wheels to prevent leaked light from this gap. CONSTITUTION:An outer pinion type counter is provided with a light shielding cover 5, with which at least the gap between display wheels 4 corresponding to display windows of a display plate is covered, between display wheels 4. The gap between display wheels 4 is covered with the light shielding cover 5 provided between display wheels 4 in this manner to not only intercept the illumination light but also conceal teeth of display wheels from view. Thus, the satisfactory visual readability is obtained though the direction of user's eyes is oblique to the display part.

[Prior Art] Generally, this type of 7-outer pinion type counter has two support shafts horizontally installed in parallel between the left and right side plates of the frame, and a plurality of display wheels are mounted on one support shaft at predetermined intervals. rotatably supported,
A pinion for digit feeding is provided on the other support shaft between the display wheels, and long teeth and short teeth are formed alternately on this pinion. The long teeth mesh with continuous teeth formed on the entire periphery of the digit side, and the long teeth mesh with intermittent teeth formed at, for example, one location on the periphery of the upper digit side of the lower digit display wheel. When the rotational force is appropriately transmitted to the lowest display wheel by the rotation transmission means, each display wheel is sequentially rotated from the lower digit side to the higher digit side via the shift pinion. It has become. In this case, a step is formed on the periphery of the upper digit side of the indicator wheel, excluding the intermittent tooth portion, and when the indicator wheel rotates, two adjacent long teeth of the pinion come into contact with the periphery of the step. This contact prevents the pinion from rotating, and when the indicator wheel on the lower digit side rotates once and the intermittent teeth of this indicator wheel reach the pinion position, the pinion rotates a predetermined angle due to the engagement between the intermittent teeth and the long teeth, and the upper digit The display wheel on the side is rotated in advance.

In an inner pinion type counter, a pinion gear for carry is interposed inside the inner peripheral surface of the display wheel, and the carry is operated from the display wheel of the lower digit to the display wheel of the higher digit in order. Therefore, when the pinion gear meshes with continuous teeth or intermittent teeth provided on the display ring, the amount of backlash between each gear is relatively small as a deviation in the display value (Equation 11) applied to the outer circumferential surface of the display ring. Because of the magnification, when viewed from the position of the display window provided for reading the display values, a phenomenon in which the display values provided on each display wheel are likely to be uneven may appear.

In this regard, in the case of an outer pinion type counter, since a pinion gear is engaged between the outer peripheral surface position of each display wheel, the gears provided on the display wheel and the pinion gear, such as continuous teeth or intermittent teeth, mesh with each other. Even if there is backlash, the pinion gear and the gear provided on the display wheel are engaged at the meshing position, that is, the position on the outer circumference of the display wheel, so the deviation in the displayed value provided on the outer circumference of the display wheel is the maximum. Even if there is, it will only be the amount of backlash between each gear, and as a result, when reading the displayed value from the display window of a counter installed on the front side of the display wheel, for example, the window frame of the display window The advantage is that you don't have to worry about it coming off.

However, in this type of outer pinion type counter, a pinion for digit feeding is provided outside between each display wheel, and the teeth of this pinion are meshed with the teeth of two adjacent display wheels. A gap of a predetermined width is inevitably created between the rings and the teeth of each adjacent indicator ring, so that the continuous teeth of the indicator ring or the intermittent teeth can be seen from the gap between each indicator ring. There is a problem in that the visibility of the displayed value is poor because the illumination light from the light source provided below the display wheel passes through the gap and leaks light.

In this way, in the above embodiment, the light-shielding cover 5 is provided between each display ring 4, and the annular peripheral wall portion 18 of this light-shielding cover 5 is formed so as to completely cover the gap between the display wheels 4, so that the display When visually reading the numbers on the display ring 4 from the display [22] on the plate 21, the annular peripheral wall portion 18 of the light-shielding cover 5 is disposed between the display wheels 4, and the continuous teeth 7 are disposed as in the conventional case.
5th stage section 9. The m-missing tooth 8 is not visible and visibility is improved. In addition, since the illumination light from a light source (not shown) is blocked by the light-shielding cover 5 and does not pass through the gap between the display wheels 411J, even if the viewing direction is oblique to the numbers, light leaks from between the display wheels 4 as in the conventional case. Good without having to? !
4. Good readability. In addition, since the light-shielding cover 5 has annular peripheral wall parts 18 and 19 integrally formed on the flat plate part 17 having the shaft hole 16, the light-shielding cover 5 can be assembled between the display wheels 4 by simply assembling the light-shielding cover 5 as a single member onto the support shaft 3. The gap and pinion 6 can be covered, assembly is easy, and the indicator wheel 4 can be covered.
The display wheel 4 can be operated from the gap between the pinions 6 and 6.
It is possible to prevent a problem in which the counter display value is intentionally subtracted by operating the counter.

FIG. 9 shows a fifth embodiment of the present invention. The same reference numerals are used for the same parts as in the first embodiment, and explanations of the same parts are omitted. In this example, a light shielding cover 50 is attached to the peripheral edge of the flat plate part 11 An annular peripheral wall part 18 is integrally formed, and an engagement recess 23 for fixing the cover is integrally formed on this annular peripheral wall part 18, and a shaft horizontally stepped on the left and right side plates 2 of the frame 1 is inserted into the engagement recess 23. 24 to fix the light shielding cover 5D. Moreover, FIG. 10 shows the sixth fruiting example of the present invention,
In this example, the light-shielding cover 5E is formed in the same manner as shown in FIG.
This makes it possible to prevent the light-shielding cover 5E from rotating by coming into contact with the inner surface of the light-shielding cover 5E. And the fifth. In the sixth embodiment as well, by covering the r1 gap between the display wheels 4 with the annular peripheral wall portion 18, the gap is hidden and light leakage is prevented.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the light shielding cover may be provided at least between the display wheels corresponding to the display windows. Further, the basic configuration of the counter can be applied to various types.
