Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
A photographic information setting device for a camera usable with a power source, comprising: a first switch, means connectable to the power source through the first switch to generate pulses, an UP-DOWN counter having photographic information set therein by said pulses, means to display the photographic information set at said UP-DOWN counter, a second switch to place said UP-DOWN counter in an activated state, and a single handling member to simultaneously handle said first switch and second switch.
Claim 2
Dependent Claim
78 words
A photographic information setting device for a camera usable with a power source, comprising: a first switch, means connectable to the power source through the first switch to generate pulses, an UP-DOWN counter having photographic information set therein by said pulses, means to display the photographic information set at said UP-DOWN counter, a second switch to place said UP-DOWN counter in an activated state, and a single handling member to simultaneously handle said first switch and second switch.
Claim 3
Dependent Claim
73 words
A photographic information setting device of a camera, having a power source, means connected to said power source through a first switch to generate pulses, an UP-DOWN counter having photographic information set therein by said pulses, means to display the photographic information set at said UP-DOWN counter, a second switch to place said UP-DOWN counter in an activated state, and a single handling member to simultaneously handle said first switch and second switch.
Claim 4
Dependent Claim
73 words
A photographic information setting device of a camera, having a power source, means connected to said power source through a first switch to generate pulses, an UP-DOWN counter having photographic information set therein by said pulses, means to display the photographic information set at said UP-DOWN counter, a second switch to place said UP-DOWN counter in an activated state, and a single handling member to simultaneously handle said first switch and second switch.
Claim 5
Dependent Claim
59 words
A device according to claim 1 or 2, in which said second switch consists of an insulating type base plate and a conductive portion on the base plate as well as a first contacting piece at said single handling member, said first switch consists of at least two conductive parts and a second contacting piece at said handling member.
Claim 6
Dependent Claim
27 words
A device according to claim 3, in which said handling member is elastically retained and keeps said contacting pieces in a neutral position in a free state.
Claim 7
Dependent Claim
71 words
A device according to claim 1 or 2, in which said second switch to place the photographic information setting circuit in an activated state includes an insulating type base plate and a conductive portion on the base plate as well as a first contacting piece at said single handling member, said switch for setting photographic information includes at least two conductive parts and a second contacting piece at said handling member.
