Abstract

A movable unit of an electronic apparatus is movable between an accommodated position within an apparatus body and a use position projected therefrom. The movable unit popped up by pop-up springs are further popped up by an assist lever and a toggle spring. The toggle spring urges the assist lever in a first arc direction and urges the same in a second arc direction opposite to the first arc direction after passing an inflexion point. The assist lever is brought into contact with a first latching pin when the movable unit reaches an end point of a movement stroke After the movable unit has reached the end point of the movement stroke, the assist lever is brought into contact with the first latching pin to urge the movable unit in the same direction as urged by the pop-up spring.

First claim

What is claimed is:

1. An electronic apparatus comprising:
an apparatus body;
a movable member configured to be movable between an accommodated position within the apparatus body and a use position in which the movable member is projected from the apparatus body;
a fixed member configured to slidably hold the movable member and fixed to a predetermined position in the apparatus body;
an urging unit configured to urge the movable member from the accommodated position toward the use position;
a lever member rotatably held by the fixed member;
a first latching member fixed to the movable member;
an urging member that has one end engaged with the lever member and the other end engaged with the fixed member, and urges the lever member such that the lever member is caused to be rotated,
wherein the lever member urges the lever member in a first arc direction, and urges the lever member in a second arc direction opposite to the first arc direction after passing an inflexion point,
wherein the lever member includes a contact portion that is brought into contact with the first latching member when the movable member reaches an end point of a movement stroke by which the movable member is moved by an urging force of the urging unit, and
wherein the lever member is brought into contact with the first latching member to urge the movable member in a direction opposite to a direction in which the movable member is urged by the urging unit, before the movable member reaches the end point of the movement stroke, and after the movable member has reached the end point of the movement stroke, the lever member is in contact with the first latching member to urge the movable member in the same direction as the direction in which the movable member is urged by the urging unit.

2. The electronic apparatus according to claim 1 , wherein when the movable member reaches the end point of the movement stroke, the urging member reaches the inflexion point.

3. The electronic apparatus according to claim 2 , wherein a straight line connecting the center of a rotational shaft of the lever member and the center of an engagement portion for engagement between the lever member and the urging member, and a straight line connecting the centers of opposite right and left ends of the urging member overlap each other at a crossing angle of 0 degrees.

4. The electronic apparatus according to claim 1 , wherein the lever member includes a first contact portion and a second contact portion which rotate about a rotational axis, and
and wherein before the urging member reaches the inflexion point, the first contact portion is brought into contact with the first latching member, and after the urging member has reached the inflexion point, the second contact portion is brought into contact with the first latching member.

5. The electronic apparatus according to claim 4 , wherein shock-absorbing members are affixed to surfaces of the first contact portion and the second contact portion of the lever member, respectively.

6. The electronic apparatus according to claim 5 , wherein the lever member and the shock-absorbing member are formed of a conductive material, and the movable member has a second latching member disposed at a location spaced from the first latching member in a moving direction of the movable member,
wherein in a case where the movable member is in the accommodated position, the first contact portion of the lever member is brought into contact with the second latching member to electrically connect between the movable member and the fixed member, and in a case where the movable member is in the use position, the second contact portion of the lever member is brought into contact with the first latching member to electrically connect between the movable member and the fixed member.

7. The electronic apparatus according to claim 6 , wherein in a case where the movable member is in the accommodated position, the second latching member pushes the first contact portion of the lever member to prevent the lever member from rotating.

8. The electronic apparatus according to claim 7 , wherein the movable member is an electronic viewfinder including an eyepiece, or a strobe device including a light emission section.

9. The electronic apparatus according to claim 1 , wherein the lever member urges the movable member in a direction opposite to the direction in which the movable member is urged by the urging unit, when the lever member is urged in the first arc direction, and urges the movable member in the same direction as the direction in which the movable member is urged by the urging unit, when the lever member is urged in the second arc direction.

10. The electronic apparatus according to claim 1 , wherein the moving speed of the movable member urged by the urging unit becomes lower as the movable member comes closer to the end point of the movement stroke.

11. The electronic apparatus according to claim 1 , wherein after the movable member has reached the end point of the movement stroke, the lever member urges the first latching member to move the movable member to the use position.
