という欠点があつた。 Conventionally, one end of the number wheel of the totalizer was fixed with a bushing, and the other end was constantly pressed by a spring, so that the lower digits were rotated in order and the totalization was performed normally.When changing the displayed value, ,
Press the number ring against the spring side, disengage the pinion between the number rings and the 2 teeth or 20 teeth of the number ring, rotate the number ring to change the numerical display, and then release the spring. However, in this conventional method, the number wheel is constantly pressed by a spring, so the drive load is large, causing wear on the drive gear and meter deflection. If this occurs and the spring is weakened, the high-order digit wheel will not be driven.

消できることを目的とする。 In order to solve the above-mentioned drawbacks, the present invention is configured so that the spacer is pressed against the spring number ring side, and the number ring and the spacer are provided with a gap by an appropriate thrust using the locking part.With this configuration, the rotation of the totalizer is Since the torque is reduced, it is possible to prevent wear of the drive gear, and since the spring can be used even if it is strong, the purpose is to eliminate problems such as idling of the number wheels of high-order digits.

落しない寸法に設定してある。 The present invention will be described below with reference to embodiments shown in the drawings. In FIG. 1, reference numeral 1 denotes a cover for a tachograph of an automobile, which houses a clock device 2, a totalizer 7, a speedometer display section (not shown), and the like. 3 is a recording paper, which is rotated at a constant speed by a clock device 2; Reference numeral 4 denotes a main body section, which incorporates a vehicle speed detection section and a recording mechanism section (not shown), and is connected to the cover 1 by a hinge 5.
The cover 1 can be opened and closed with respect to the main body part 4. 6 is the totalizer cover, and the totalizer 7 is fixed with screw 9 etc.
is sealed to prevent unauthorized manipulation. Reference numeral 8 denotes a transmission shaft that drives the totalizer from a vehicle speed detection section (not shown) of the main body 4 via a reduction gear. In FIG. 2 showing the totalizer 7, a frame 11 includes a support hole 11a for a shaft 14, a rotation prevention locking portion 11b for a support plate 17, and a gear receiving portion 11c. The transmission shaft 8 is adapted to drive a gear shaft 12 by a gear (not shown) in a gear receiving portion 11c, and a gear 12a on the gear shaft 12 is meshed with a first gear 13 of an integrated meter. The protrusion 13a provided on the outer periphery of the gear 13 is 20 of the number wheel 16 of the lowest digit.
Engages with the teeth. Two teeth are formed on the higher side side of the number ring 16, and a pinion 18 meshes with these two teeth and the 20 teeth of the higher digit at the same time, and the pinion 18 is arranged between each number ring 16. The support plate 17 rotates in a fixed position. Then, there are buttons 15 and 1 on the highest digit and lowest digit sides of these number wheels 16, respectively.
9 is press-fitted and fixed to prevent it from coming off. Note that this totalizer is the same as a known built-in totalizer. The number wheel 16 and the support plate 17 are supported by the shaft 14, so that the number wheel 16 can rotate. The bush 19 only on the highest digit number wheel 16 side has a gap B so that the number wheel 16 can move somewhat in the axial direction of the shaft 14. A cup-shaped spacer 20 having a flange 20a and a locking portion 20b is provided on the shaft 4 between the pusher 19 and the frame 11, and this spacer 20 comes into contact with the pusher 19 by an elastic member 21 such as a spring. It is pressed until At this time, the flange 20a has the number ring 16.
The highest digit side and appropriate gap (usually 0.1 to 0.3 mm)
A. Spacer 20
is movable in the axial direction of the shaft 14 by a distance B' against the pressing force of the spring 21. Dimensions B and B' are slightly larger than the meshing amount C between the pinion 18 and the 2 teeth and 20 teeth of the number ring 16, and the pinion 1
8 is set to such a size that it will not fall off from the support shaft 17a of the support plate 17.

荷が加わることなく円滑に積算駆動できる。 The operation will be explained in the above embodiment. A transmission shaft 8, a gear shaft 12, and a first gear 1 are connected to a drive shaft (not shown).
3, the number wheel 16 performs one rotation of the lower digit, and the adjacent upper digits are integrated by 1/10 rotation. Here, since the spacer 19 is pressed by the spring 21 and its locking portion 20b comes into contact with the bush 20, a proper gap A is created between the flange 20a of the spacer 20 and the highest digit of the number ring 16.
is formed, and the spring force of the spring 21 is not applied to each number wheel 16, so that each number wheel 16 can be smoothly cumulatively driven without applying an excessive load.

高位桁側から同様に行なつても可能である。 Furthermore, in the case where the totalizer 7 is out of order and only the totalizer 7 is replaced with a new one, the display on the totalizer must match the previous one. In this way, when changing the number displayed on the totalizer 7 to match the previous one, push the number wheel 16 of the lowest digit toward the higher digit to adjust the meshing with the first gear 13. Remove it, turn the number wheel of the lowest digit to display the desired number, and engage it with the first gear 13. Then,
The pinion 18 and the support plate 17 are brought together to the number ring of the lowest digit, and the two pinions 18 are engaged with the tooth surfaces. The pinion 18 is engaged with the support plate 17 by turning the number wheel of the next digit so as to display the desired number. By performing the above operations for the upper digits in order, all number rings can be adjusted to match the desired digits. Then, when all the digits are finished, release your hand and the spacer 20 will spring 21.
is pressed and returns to the original position, and is set while maintaining the predetermined gap dimension A. Note that this operation can also be performed in the same way from the higher-order digit side.
