A conventional mechanical totalizer mechanism has a structure as shown in FIG. This is a partial structure showing the main part, 1 is the instrument frame, this instrument frame 1
The support shaft 2 and the sub-support shaft 3 provided parallel to the support shaft 2 are constructed and held, and one of the support shafts 2
A drive gear 5 rotated by the rotation of the drive gear 4 and a plurality of integration wheels 6 are inserted and supported in a skewed manner, and the other support shaft 3 is provided with a drive gear 5 that is rotated by the rotation of the drive gear 4, and a plurality of integration wheels 6 are inserted and supported in the form of a skewer. , a plurality of shift pinions 7 that are engaged with a shift claw group 6' formed on the side surface of each integration wheel 6, and are engaged with the integration wheel 6 of the lowest digit and the drive gear 5. is inserted and supported in the form of a skewer. A flange 8 having the same diameter as the outer diameter of the integrating wheel 6 is integrally formed on the drive gear 5 from resin. Two gear teeth 9 are formed to mesh with each other to rotate the gear pinion 7.

お７ｂは桁送りピニオン７の長歯を示す。 However, in the case of the resin drive gear 5, due to dimensional errors during molding, etc., when the drive gear 5 is inserted and supported on the support shaft 2, there is a gap between the drive gear 5 and the support shaft 2. If a large gap or the like occurs, the shaft will be tilted with respect to the support shaft 2, as shown in FIG. 5, for example. When the drive gear 5 is tilted in this way, the tips of the short teeth 7a of the shift pinion 7, which normally would not come into contact with the circumferential surface of the flange 8, may
As shown in FIGS. 5 and 6, the tip of the shift pinion 7 is not rotated due to the rotation of the flange 8 because the tip thereof is in contact with the circumferential surface of the flange 8, as shown in FIGS. There was a problem that an accident such as damage to the shift pinion 7 or the shift pinion 7 could occur. Note that 7b indicates long teeth of the shift pinion 7.

The present invention was developed by focusing on such conventional problems, and it is possible to approach the front and rear of the two teeth formed on the flange of the drive gear so that the short teeth of the shift pinion come into contact with the flange circumferential surface. It is an object of the present invention to provide a totalizer that can solve the above problems by providing a chamfered portion (notch) to prevent contact.
以下に本考案を第１乃至第３図に示す実施例に

The present invention will be explained in detail below based on the embodiment shown in FIGS. 1 to 3. The same parts between the structure in this embodiment and the structure shown in the conventional example will be designated by the reference numerals cited in the conventional example. The structural description will be omitted.

That is, in the case of this drive gear 5, chamfered portions 10 are formed at the front and rear adjacent peripheral edges of the two shift teeth 9 provided on the flange 8 to reduce the thickness of the flange 8. .

円滑に動作させることができる。 By providing the chamfered portions 10 adjacent to the front and rear of the two shift teeth 9 of the drive gear 5, the use of this drive gear prevents the support shaft 2 Even if the second
As shown in the figure, the end of the short tooth 7a of the shift pinion 7 does not come into contact with the circumferential surface of the flange 8, in other words, the end of the short tooth 7a does not come into contact with the chamfered surface. 10 allows the shift pinion 7 to rotate smoothly as the drive gear 5 rotates.

される等の効果もある。 Therefore, according to this embodiment, there is a dimensional error in resin molding of the drive gear 5, and the error may cause the drive gear 5 to be assembled in an inclined manner with respect to the support shaft 2. However, the circumferential surface of the flange part of the drive gear and the shift pinion 7
The provision of the chamfered portion 10 prevents the two from coming into contact (meshing), so the rotational force of the drive gear is smoothly transmitted to the shift pinion.
As a result, the drive gear 5 and the shift pinion 7 are not damaged, and durability and reliability are improved.

As described above, in the present invention, the drive gear 5 adjacent to the lowest digit integration car of the plurality of integration cars 6 is connected to the support shaft 2.
an auxiliary support shaft 3 that is pivotally supported by the support shaft 2 and extends parallel to the support shaft 2;
A group of digit-feeding pawls 6' and two teeth 9 for digit-feeding are interposed between each of the totalizing wheels 6 and between the lowest-digit totalizing wheel 6 and the drive gear 5, and are provided on the side thereof. In the totalizer, a matching shift pinion 7 is pivotally supported and the integration wheel 6 is sequentially driven for integration according to the rotation of the drive gear 5. This totalizer is characterized in that a chamfered portion 10 is formed on the periphery of the drive gear 5 at the front and rear.

Therefore, according to the totalizer of this invention, there is a dimensional error in the resin molding of the drive gear 5,
Due to this error, the drive gear 5
Even if it is assembled in an inclined manner,
Since the circumferential surface of the flange portion of the drive gear and the shift pinion 7 do not come into contact (mesh) with each other due to the provision of the chamfered portion 10, the rotational force of the drive gear is transferred to the shift pinion. The transmission is carried out smoothly, and as a result, the drive gear 5 and the shift pinion 7 are not damaged, and durability and reliability are improved.
