Electrically driven camera mechanisms

Claim 2

A mechanism for controlling an electrically driven camera having an electric motor, a release member operated by rotation of the electric motor, and a film winding means driven by the electric motor with the operation of the release member after the completion of an exposure, comprising: a release button; a first switch connecting said electric motor to a power source; a switching means for selectively connecting said release button with said first switch and said release button with said release member, said switching means comprising: a selection member displaceable between a first position and a second position; means for connecting said release button to said release member when said selection member is at said first position; and a first switch actuating member closing said first switch by releasing said release button when said selection member is in said second position.

Claim 3

A mechanism as in claim 1, wherein said switching means further comprises: a shaft rotatable between a first position and a second position; a cam plate mounted to said shaft; a connecting lever operated by said cam plate and urged to a position for connecting said release button with said release member with said shaft in said second position; and first switch actuating lever operated by said cam plate and closing said first switch in association with the release movement of said release button with said shaft in said second position.

Claim 4

A mechanism as in claim 1, wherein said switching means further comprises: a lock member for arresting the release of said release button to disconnect said release button and said release member.

Claim 5

A mechanism for controlling an electrically driven camera having an electric motor, a release member operated by rotation of the electric motor, and a film winding means driven by the electric motor with the operation of the release member after the completion of an exposure, comprising: a release button; a first switch connecting said electric motor to a power source; a switching means for selectively connecting said release button with said first switch and said release button with said release member; a differential gear driven by said electric motor to produce first and second outputs, said differential gear generating said first and second outputs depending upon the variation of a load applied to both said outputs; a film winding mechanism operated by said first output; and a cam driven by said second output for actuating said release member.

Claim 6

A mechanism for controlling an electrically driven camera having an electric motor, a release member operated by rotation of the electric motor, and a film winding means driven by the electric motor with the operation of the release member after the completion of an exposure, comprising: a release button; a first switch connecting said electric motor to a power source; a switching means for selectively connecting said release button with said first switch and said release button with said release member; a differential gear driven by said electric motor to produce first and second outputs, said differential gear generating said first and second outputs depending upon the variation of a load applied to both said outputs; a film winding mechanism operated by said first output; and a cam driven by said second output for actuating said release member.

Claim 7

A mechanism as in claim 4, further comprising: an electromagnet connected to said power source when said first switch is closed; a second switch operated by said electromagnet and connecting said power source to said electric motor; a third switch operated by said electromagnet and switching between a circuit for short-circuiting said electric motor and a circuit connected in parallel with said second switch and connecting said electric motor to said power source; a second switch actuating lever operated in association with said cam; a second switching means for connecting or disconnecting a fourth switch connected in series with said third switch and operated by said second switch lever and a fifth switch connected to said second switch and operated by said second switch lever; and a sixth switch connected in parallel with said second switch and manipulated to switch between one-frame photography and continuous photography.

Claim 8

A mechanism for controlling an electrically driven camera having an electric motor, a release member operated by rotation of the electric motor, and a film winDing means driven by the electric motor with the operation of the release member after the completion of an exposure, comprising: a release button axially movable for the release operation and displaceable in another direction between a first position and a second position; a first switch connecting an electric motor with a power source; and a means for directing the axial directional displacement of said release button to said release member when said release button is in said first position and for directing the axial displacement of said release button to the opening or closing of said first switch when said release button is in said second position.

Claim 9

A mechanism for controlling an electrically driven camera having an electric motor, a release member operated by rotation of the electric motor, and a film winDing means driven by the electric motor with the operation of the release member after the completion of an exposure, comprising: a release button axially movable for the release operation and displaceable in another direction between a first position and a second position; a first switch connecting an electric motor with a power source; and a means for directing the axial directional displacement of said release button to said release member when said release button is in said first position and for directing the axial displacement of said release button to the opening or closing of said first switch when said release button is in said second position.

Claim 10

A mechanism as in claim 6, wherein said release button is rotatable in said another direction about the axial movement thereof between said first position and said second position.

Claim 11

A mechanism as in claim 6, wherein said release button is slidable between said first position and said second position in a direction normal to the axial directional movement thereof.
