と夫々互いに係合する様になされている。 Conventionally, timers for electrical appliances, etc. are often set for relatively short time periods, and although many require setting for long time periods, the set time periods are generally displayed approximately equally. It is used as a scale. Therefore, the accuracy of the time limit setting is constant, and sufficient setting accuracy cannot be obtained for parts that are frequently set and require setting accuracy. In view of this, for example, a speed change gear system installed on the main shaft of a timer is used to rotate the pointer in stages according to the rotational speed of the main shaft, which is frequently set and requires high setting accuracy. An enlarged display timer has been proposed in which the time limit display is enlarged and the setting accuracy of this part is improved. Regarding one example, the first
To explain with reference to the drawings and FIGS. 2 and 2, first, as shown in FIG. It is assumed that it is familiar.

をオフしてタイマーは停止する。 To explain the operation of a conventional example having such a configuration, FIGS. 1 and 2 each show a timer stopped state, and from this state, when the main shaft 1 is set in the direction of arrow a with a knob (not shown) according to a desired time, Due to the rotation of the first transmission gear 4 in the direction of arrow a,
The spindle wheel 10 rotates in the direction of arrow C, thereby causing the first deformation gear 5 and the pointer 7 to rotate in the direction of arrow a. At this time, the large-diameter portion 14 of the second deformable gear 11 and the small-diameter portion 15 of the first deformable gear 5 rotate together, and the pointer 7 rotates at a higher speed than the rotational speed of the main shaft 1. Small diameter portion 16 of deformed gear 11
At the same time, the pointer 7 rotates at a speed lower than the rotational speed of the main shaft 1. After setting, the clock device is driven by the repulsive force of the mainspring, and the main shaft 1 starts moving in the direction of arrow b at a constant speed. And the support wheel 10 is indicated by the arrow d
The first deformable gear 5 and the pointer 7
The part where the small diameter part 16 of the second deformable gear 11 and the large diameter part 13 of the first deformable gear 5 rotate at a low speed relative to the rotational speed of the main shaft 1, and then the second deformed gear The portion where the large diameter portion 14 of the gear 11 and the small diameter portion 15 of the first deformable gear 5 rotate in conjunction with each other rotates at a higher speed than the rotational speed of the main shaft 1. When the set time elapses in this way, that is, when the pointer 7 reaches the 0 indication on the time scale, a switch (not shown) is activated by a cam mechanism (not shown) connected to the main shaft 1.
is turned off and the timer stops.

時限目盛の０の目盛位置を指示しないという難点
があつた。 However, in the conventional example explained above, the second
Due to the backlash between the transmission gear 12 and the first transmission gear 4 and the backlash between the second deformation gear 11 and the first deformation gear 5, etc., the first deformation gear 5 moves freely with respect to the main shaft 1. (backlash) becomes very large, and therefore, the pointer 7 fixed to the upper sword barrel 6 of the first deformable gear 5 has a drawback that it moves widely. For this reason, even if an attempt is made to set an accurate time limit, it becomes inaccurate due to the amount of movement of the pointer 7, and it is difficult to set the time limit accurately in accordance with the time scale. Another problem is that the pointer 7 moves loosely due to vibrations caused by the operation of the cam mechanism at the moment the timer is turned off from the operating state, so that the pointer 7 does not indicate the zero position of the time scale.
以上の様に従来の拡大表示タイマーでは指針の
遊動のために頻繁に設定され且つ設定精度を必要

つた。 As described above, the conventional enlarged display timer has the disadvantage that it cannot achieve the purpose of the enlarged display timer, which is to improve the setting accuracy of a part that is frequently set due to the movement of the pointer and requires setting accuracy.

防止する様にしたものである。 The present invention was developed in view of the above drawbacks, and an elastic member is attached to the first deformable gear loosely fitted to the main shaft of the enlarged display timer, and the pointer is always urged in a fixed direction by the repulsive force of the elastic member. This prevents the pointer from fluctuating due to backlash in the speed change gear system.

ものとする。 An embodiment of this invention will be explained below with reference to FIGS. 3 and 4. 1 to 12 in FIG. 3 have the same structure as the conventional example shown in FIG. 1, and 17 is a coil spring, for example. The upper and lower ends 18 and 19 of the elastic member are connected to the first deformable gear 5.
and the upper surface of the first transmission gear 4, respectively, and always urges the first deformable gear 5 in a constant direction (direction of arrow b) with respect to the first transmission gear 4. .

回転する。 To explain the operation in such a configuration, the third
As shown in the figure, when the main shaft 1 is set using a knob (not shown) in the direction of the arrow a according to a desired time, the first deformable gear 5 is moved along with the pointer 7 via the first transmission gear 4 and the spindle 10 to the direction indicated by the arrow a. Rotate in the direction. At this time, since the elastic member 17 always urges the first deformation gear 5 in the direction of arrow b, the pointer 7 fixed to the upper sword barrel 6 of the deformation gear 5 always moves in the direction of arrow b with respect to the main shaft 1. Even when the watch device is driven by the repulsive force of the mainspring after being set and the main shaft 1 rotates at a constant speed in the direction of arrow b, the elastic member 17 remains in the first deformation state. gear 5
Since the pointer 7 is always urged in the direction of the arrow b, the pointer 7 is always urged in the direction of the arrow b with respect to the main shaft 1, and the pointer 7 is not affected by the backlash of each gear and is always in the direction of the main shaft 1. Rotates following the rotation of.

ない実用的効果がある。 As described above, according to this invention, since the pointer is prevented from drifting, it becomes possible to accurately align the pointer with the time scale, and the setting accuracy is dramatically improved. In addition, it is possible to eliminate the movement of the pointer due to the vibration of the cam mechanism at the moment the timer is turned off from the operating state, that is, the pointer moves from the 0 scale indicating state of the time scale, which has not been seen in the past. It has practical effects.
