Abstract
A force multiplier (5) configured to assist movement of the operating rod (22) in its axial direction is provided. An engagement recess (52) provided on an outer periphery of the operating rod (22) has a cam surface (52a) configured to make engagement with an engagement ball (51). There is provided a support hole (53) configured to allow movement of the engagement ball (51) in a radial direction of operating rod (22) and to restrict movement of the engagement ball (51) in the axial direction of the operating rod (22). A pressing member (54) configured to press the engagement ball (51) is provided, and the pressing member (54) has a force-multiplying surface (54a).
Claims5
An output device comprising:
- an operating rod (22) inserted into a housing (1) so as to be movable in an axial direction of the operating rod (22), the operating rod (22) being configured to be moved in the axial direction by an external force in the axial direction applied to an end portion of the operating rod (22);
- a force multiplier (5) provided between the housing (1) and the operating rod (22), the force multiplier (5) being configured to assist movement of the operating rod (22) in the axial direction;
- and
- an output rod (21) configured to be moved by the operating rod (22) in a direction crossing the axial direction of the operating rod (22), wherein
- the force multiplier (5) includes:
- an engagement member (51);
- an engagement recess (52) provided on an outer periphery of the operating rod (22) and configured to receive the engagement member (51) in a fitted manner, the engagement recess (52) having a cam surface (52a) configured to make engagement with the engagement member (51);
- an engagement member supporter (53) configured to allow movement of the engagement member (51) in a radial direction of the operating rod (22) and to restrict movement of the engagement member (51) in the axial direction of the operating rod (22);
- a pressing member (54) configured to be biased by a spring (55) thereby to press the engagement member (51), the pressing member (54) having a force-multiplying surface (54a) configured to make engagement with the engagement member (51);
- a guide member (35) provided at a base-side portion of the output rod (21);
- and
- a cam groove (38) provided in the operating rod (22) so as to be directly or indirectly make engagement with the guide member (35), the cam groove (38) having a driving groove portion (40) extending so that a distance from an axis of the operating rod (22) increases toward one of opposite axial ends of the operating rod (22).

An output system comprising:
- an output device including:
- an operating rod (22) inserted into a housing (1) so as to be movable in an axial direction of the operating rod (22), the operating rod (22) being configured to be moved in the axial direction by an external force in the axial direction applied to an end portion of the operating rod (22);
- a force multiplier (5) provided between the housing (1) and the operating rod (22), the force multiplier (5) being configured to assist movement of the operating rod (22) in the axial direction;
- and
- an output rod (21) configured to be moved by the operating rod (22) in a direction crossing the axial direction of the operating rod (22), wherein
- the force multiplier (5) includes:
- an engagement member (51);
- an engagement recess (52) provided on an outer periphery of the operating rod (22) and configured to receive the engagement member (51) in a fitted manner, the engagement recess (52) having a cam surface (52a) configured to make engagement with the en-gagement member (51);
- an engagement member supporter (53) configured to allow movement of the engagement member (51) in a radial direction of the operating rod (22) and to restrict movement of the engagement member (51) in the axial direction of the operating rod (22);
- and
- a pressing member (54) configured to be biased by a spring (55) thereby to press the engagement member (51), the pressing member (54) having a force-multiplying surface (54a) configured to make engagement with the engagement member (51);
- and
- a stocker (100) including a guide surface (90b, 91a) for the movement of the operating rod (22) in the axial direction,
- the stocker (100) comprising:
- a placement table portion (86, 87) configured to support an object (70) placed thereon and to be clamped by the output device;
- and
- a guide groove (90, 91) including the guide surface (90b, 91a) provided on an inner surface of the guide groove (90, 91), and functioning as a guide for the end portion of the operating rod (22), the guide surface (90b, 91a) having a tapered shape, wherein
- the movement of the operating rod (22) in the axial direction is achieved through insertion of the end portion of the operating rod (22) protruding from the housing (1) into the guide groove (90, 91) to bring the end portion into contact with the tapered guide surface (90b, 91a).
