【考案の詳細な説明】 本考案は緩衝装置に係り、特に過負荷時に駆動電源を自
動的に遮断又は離脱させる様にした緩衝装置に関する。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shock absorbing device, and more particularly to a shock absorbing device that automatically shuts off or disconnects the driving power supply in the event of an overload.

従来、駆動源よりの駆動力をギヤ等の伝達手段を介して
負荷を駆動させるものに於ては負荷を急激に伴出させた
場合、負荷の変動が直ちに駆動源に応答せず、負荷を破
損に導く等の幣害を生ずる。
Conventionally, in a device that drives a load by using the driving force from a drive source through a transmission means such as a gear, when the load is suddenly applied, the load fluctuation does not immediately respond to the drive source and the load is This may cause financial damage such as damage.

このため負荷を停止させるためのスイッチ「オフ」操作

For this reason, a device is known in which a brake force is applied to the drive source at the same time as the switch is turned off to stop the load.

然し、この装置によると直ちに駆動源は停土せず負荷を
破損に導く等の欠点を生ずる。
However, with this device, the drive source does not come to a standstill immediately, resulting in disadvantages such as the load leading to damage.

Alternatively, when the driving force is transmitted to the load via a transmission means, it is possible to remove the transmission means, such as a gear, using a plunger or the like, but this increases the cost and causes problems such as generation of noise.

Further, in the case where a belt is used as a transmission means, it may be possible to make the drive source respond to sudden changes in load by utilizing the elongation or slippage of the belt, but this poses problems such as the longevity of the belt.

Furthermore, as shown in FIG. 1, the driving force from the driving source 1 rotates the first gear 3 fitted on the shaft 2 of the drive motor of the driving source, and the gear 5 is connected to the first intermediate shaft 6. The third gear meshes with the second gear 4 of the fitted second and third gears 4 and 5, and the third gear meshes with the fourth and fifth gears 8 and 9 fitted onto the second intermediate shaft T. It meshes with the fifth gear 9 and is arranged so that the load is driven by the fourth gear 8 (not shown).
A friction member 10 having a relatively large friction coefficient, such as a friction washer, is inserted into the first intermediate shaft 6 to prevent sudden changes in the load on the drive motor 1 and to buffer it. There are also known devices that do this.

然し、この構成では熱的な変化により摩擦部材の摩擦係
数が変化し、不安定に成る欠点を有する。
However, this configuration has the disadvantage that the friction coefficient of the friction member changes due to thermal changes, resulting in instability.

Further, the plate 11 is fixed to the drive motor 1 with a screw 12, and the plate 11 is rotatably attached to the intermediate shaft 6 to which the second gear 4 is attached, and the first gear and the second gear are meshed. The first gear 3 transmits the driving force of the drive motor, and the first gear 3 makes a planetary motion with respect to the second gear 4. In the case of the springs 13' and 14' shown by broken lines in FIG. 2, the direction of tension of the springs is set within the tangent to reduce the planetary motion. It is a stage designed in a similar manner.

In this state, when the cassette hits the head or pinch roller, even if the drive motor 1 is turned off, due to the inertia of the drive motor 1 and the transmission means, the end position of the cassette will reach the point indicated by the arrow.
A large pressing force is applied in this direction, leading to damage to the cassette, drive motor, etc. Therefore, in the case of the present invention, when such a reaction force is applied, the drive source is moved through the opposite path to the first intermediate Since it is instructed to rotate around the shaft 6, in this case, the drive source rotates by the amount that the spring 13, 140 is unbalanced, and the sudden change in load is compensated for.
