【考案が解決しようとする課題】[Problems to be solved by the device]

従来の回転カム構造は、以上のように構成されていたため、次のような課題が 存在していた。 すなわち、前述の構成による回転カム構造を用いて、例えば、パチンコ装置の 玉を打出す場合、このモータ側の振動がパチンコ装置の部品に伝達又は共振する ことにより、パチンコ装置自体が不快な振動あるいは騒音を出すことになり、パ チンコ装置の騒音の増大となっていた。 Since the conventional rotary cam structure is configured as described above, there are the following problems. That is, for example, when a ball of a pachinko machine is shot using the rotating cam structure having the above-described structure, the vibration on the motor side is transmitted to or resonates with the parts of the pachinko machine, which may cause an uncomfortable vibration or Noise was generated, and the noise of the pachinko machine increased.

【0005】 本考案は、以上のような課題を解決するためになされたもので、特に、モータ の回転軸に設けられたカム体に対してモータからの振動及びモータと打出し装置 との共振音を抑えるようにした回転カム構造を提供することを目的とする。The present invention has been made to solve the above problems, and in particular, the vibration from the motor and the resonance between the motor and the driving device with respect to the cam body provided on the rotating shaft of the motor. It is an object of the present invention to provide a rotating cam structure that suppresses noise.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

本考案による回転カム構造は、モータの回転軸に設けられたカム体を有し、こ のカム体が前記回転軸と共に回転するようにした回転カム構造において、前記回 転軸とカム体間に弾性体が設けられている構成である。 The rotary cam structure according to the present invention has a cam body provided on a rotary shaft of a motor, and the cam body is configured to rotate together with the rotary shaft, wherein between the rotary shaft and the cam body. This is a configuration in which an elastic body is provided.

【0007】 さらに詳細には、前記カム体を固定するため前記カム体及び弾性体を貫通して 前記回転軸に固定された取付ねじと、前記取付ねじと前記カム体及び弾性体間に 設けられた弾性ブッシュとを備えた構成である。More specifically, the mounting screw is fixed to the rotating shaft by penetrating the cam body and the elastic body for fixing the cam body, and is provided between the mounting screw and the cam body and the elastic body. And an elastic bush.

【0008】 本考案による回転カム構造は、モータの回転軸に設けられたカム体を有し、こ のカム体が前記回転軸と共に回転するようにした回転カム構造において、前記カ ム体は弾性体よりなる構成である。The rotating cam structure according to the present invention has a cam body provided on a rotating shaft of a motor, and the cam body rotates together with the rotating shaft, wherein the cam body is elastic. It is composed of a body.

【0009】[0009]

【作用】[Action]

本考案による回転カム構造においては、カム体自体が弾性体よりなるか、又は 、カム体と回転軸間に弾性体が設けられているため、回転軸を伝達するモータの 振動等は、カム体を介して他の打出し装置等への伝達が抑えられ、従来のような 振動の伝達及び共振を防止することができる。 In the rotating cam structure according to the present invention, since the cam body itself is made of an elastic body or an elastic body is provided between the cam body and the rotating shaft, the vibration of the motor transmitting the rotating shaft, etc. It is possible to suppress the transmission to other driving devices and the like through the via, and to prevent the transmission and resonance of vibration as in the conventional case.

【実施例】【Example】

以下、図面と共に本考案による回転カム構造の好適な実施例について詳細に説 明する。なお、従来例と同一又は同等部分については同一符号を用いて説明する 。 図1において、符号1で示されるものは、前蓋2及び後蓋3で挟持されたステ ータであり、このステータ1内のロータ(図示せず)に接続された回転軸4の軸 端4aにはキャップ状の弾性体10を介してカム体5が取付ねじ6により固定さ れている。 Hereinafter, preferred embodiments of the rotating cam structure according to the present invention will be described in detail with reference to the drawings. The same or equivalent parts as those of the conventional example will be described using the same reference numerals. In FIG. 1, reference numeral 1 is a stator sandwiched by a front lid 2 and a rear lid 3, and a shaft end of a rotary shaft 4 connected to a rotor (not shown) in the stator 1. A cam body 5 is fixed to 4a by a mounting screw 6 via a cap-shaped elastic body 10.

【0011】 前記カム体5は、カム部5aと取付部5bとからなり、この取付部5bの凹部 5ba内に前記弾性体10が挿入されている。この取付部5bに形成された取付 孔5bb内には全体形状がほぼT字型をなす弾性ブッシュ11が設けられ、この 弾性ブッシュ11の孔11a及び弾性体10の孔10aを貫通して設けられた取 付ねじ6のねじ部6aは前記回転軸4の軸端4aに形成されたねじ孔4bに螺入 されている。The cam body 5 includes a cam portion 5a and a mounting portion 5b, and the elastic body 10 is inserted into a recess 5ba of the mounting portion 5b. In the mounting hole 5bb formed in the mounting portion 5b, an elastic bush 11 whose overall shape is substantially T-shaped is provided. The elastic bush 11 is provided so as to penetrate the hole 11a of the elastic bush 11 and the hole 10a of the elastic body 10. The screw portion 6a of the mounting screw 6 is screwed into the screw hole 4b formed in the shaft end 4a of the rotary shaft 4.

【0012】 従って、このモータの回転時に、ロータから伝わる振動は、この弾性体10及 び弾性ブッシュ11を介してカム体5に伝達されにくく、従来のように、このカ ム体5に連動する例えばパチンコ装置の打出し部へ伝達して共振するような現象 を防止することができる。Therefore, when the motor rotates, the vibration transmitted from the rotor is difficult to be transmitted to the cam body 5 through the elastic body 10 and the elastic bush 11, and is linked to the cam body 5 as in the conventional case. For example, it is possible to prevent a phenomenon in which the pachinko machine is resonated by being transmitted to the launching section.

【0013】 なお、前述の実施例において、弾性ブッシュ11を用いず、弾性体10のみの 場合も十分な効果を得ることができると共に、前述の弾性体10及び弾性ブッシ ュ11を用いることなく、前記カム体5自体を弾性体で構成した場合も同様の効 果を得ることができるものである。It should be noted that in the above-described embodiment, sufficient effects can be obtained even when the elastic bush 11 is not used and only the elastic body 10 is used, and the elastic body 10 and the elastic bush 11 are not used. The same effect can be obtained when the cam body 5 itself is made of an elastic body.

【考案の効果】[Effect of device]

本考案による回転カム構造は、以上のように構成されているため、カム体に伝 達される振動やそれにより発生する共振を防止し、例えば、パチンコ装置等の騒 音や共振を防止することができる。 Since the rotary cam structure according to the present invention is configured as described above, it is possible to prevent the vibration transmitted to the cam body and the resonance generated thereby, for example, to prevent the noise and resonance of the pachinko machine. You can
