Description

[Detailed Description of the Invention] The present invention relates to an odometer that cumulatively displays the distance traveled by an automobile.

Conventional totalizers are configured so that each time the number wheel rotates once due to the rotation of the drive shaft, the rotating number wheel that displays the adjacent high-order digit totalizes by 1/10 rotation due to the action of the pinion between the number wheels. 1 The lowest point for a normal automobile odometer is 0. I Ian, and it is composed of 6 digits so that the maximum digit is displayed in tens of thousands.

When the drive shaft is reversed, the subtraction is performed in the opposite manner to the above.

There have also been proposals that indicate when the reverse rotation occurs by making a scratch on the outer periphery of the rotation indicator wheel of the used upper digit with a cutting tool or applying paint or ink.

Incidentally, in conventional configurations, fraud is often carried out by taking advantage of the fact that the display on the totalizer decreases due to reverse rotation of the drive shaft.

for example. When it comes to used car odometers, fewer mileage is more advantageous in terms of sales, so fraud is particularly likely to occur when it comes to 10,000 units.

In addition, in the case of the anti-tamper display totalizers that have been proposed in the past, if they are scratch-resistant, the load placed on the rotating number wheel is large, and in severe cases, it may be difficult to perform normal totalization due to wear or idling of the drive gear. In addition, in the case where ink or paint is applied, there is a problem that the □ display cannot be performed reliably due to drying or evaporation over a long period of time.

In order to improve this point, the present invention uses pressure-sensitive recording to display a used mark on the surface of the high-order digit rotation number wheel of a used totalizer, so that if the number wheel is rotated backwards for one rotation and fraud is committed. , the purpose is to reliably display fraud without interfering with the totalization function.

The present invention will be described below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an integrator that displays an integrated value based on the rotation □ of a drive source (not shown).

In the totalizer 1, rotary number wheels 2 and 2' with numbers 2a printed on their outer peripheries are rotatably supported on a shaft 7.
In order to display blood in tens of thousands, there are six adjacent ones.

A spacer plate 3 is provided between each number ring 2, 2' and rotatably supports a pinion (not shown).

This pinion meshes with both two teeth and twenty teeth (not shown) of each number ring 2, 2'.

Only the most significant digit of the number wheels 2 and 2' has the following configuration,
The other number rings are molded with black or white resin, and the number 2a is displayed on the outer peripheral surface of the number ring using a white or black hot stamp.

A pressure-sensitive recording paper 4 is fixed to the outer periphery of the top number wheel 2' by means such as double-sided adhesive tape.

The recording paper 4 has a red colored layer 4b formed on the surface of a recording base paper 4d, a white paraffin layer 4a formed thereon, and a black colored layer 4c formed thereon except for the number 2a part ( However, the color is not relevant to this invention).

This recording paper may be formed as described in Japanese Patent Publication No. 35-7879, for example.

A pressure-sensitive recording pen 5 is provided opposite the most significant digit number wheel 2'.

One end of this pen 5 has a 3-point tip so that the tip forms three pens.
It is divided.

The other end of the pen 5 is fixed to a frame portion 6 of the totalizer body or the like with a screw 6a.

The pen 5 is made of a phosphor bronze spring material with elasticity in order to keep the pressure of the recording pen 5 at the tip constant.

Therefore, the pressure at the tip of the pen 5 is about 5-209.

With the above structure, the rotating number wheels 2 and 2' accumulate numbers sequentially from the lower digits as the drive source rotates, and when the number wheel 2' of the highest digit is driven, this number wheel 2' Since the black colored layer 4c and the white paraffin layer 4a in the vicinity of the numbers immediately after the display of the pressure-sensitive recording layer 4 on the surface of the number wheel 2' are scraped off by the pen 5 provided in opposition to each other, the red colored layer 4b is scraped off.
appears as a marking line 8 to indicate that it has been used.

Here, the recording density of the pressure-sensitive recording paper 4 can be adjusted by the pressure of the pen tip 5, and for the recording paper of the embodiment, 5 to 2 (Bi' is suitable, but if a soft recording layer 4 is used, 5 g
It can also be used below.

In the above embodiment, the pressure-sensitive recording paper 4 was fixed to the outer periphery of the one-turn number wheel 2' using double-sided adhesive tape, but the red colored layer 4b was formed directly on the number wheel 2'. A white paraffin layer 4a and a black colored layer 4c may be formed thereon as described above, or the number wheel 2 may be molded with red resin, and the white paraffin layer 4a, on the surface of the number ring 20.
A black colored layer 4c may also be formed.

Further, if there is no need to make the display color stand out as described above, the red colored layer 4b may be omitted and the numbers may be displayed using the number ring 2' and the black colored layer 4c on top of the white paraffin layer 4a. There is no problem even if only the paraffin layer 4a is provided directly on the outer periphery of the number ring 2'.

Alternatively, the pen 5 may be made of other non-elastic material and fixed to the frame portion 6 via an elastic material such as a spring or rubber.

In addition, the reason why the tip of the pen 5 is divided into three parts is to make the recording line 8 thinner to reduce the recording resistance, and to make the display clearer by making multiple displays. It is not necessarily necessary to divide.

As described above, in the present invention, a pressure-sensitive recording layer is formed on the outer circumferential surface of the rotary number wheel of the uppermost digit, and a recording member □ that is in contact with the rotary number wheel and allows pressure-sensitive recording to be made on the recording layer.
Since it is constructed to have elasticity, it is possible to display the used part of the 1-turn number wheel, and it is possible to reliably display fraud even if the totalizer is reversed, and because it has a pressure-sensitive recording layer. Recording can be performed reliably without drying out or evaporating even after a long period of time, and since the recording member is constructed to have elasticity, the resistance applied to the rotating number wheel is less likely to cause scratches. It is significantly smaller than the conventional one, does not cause gear wear or slippage, and has excellent effects such as reliable recording and display.
