Claim 2
Dependent Claim
69 words
A video phone unit in claim 1 in which the first selecting means (9, 35) selects the photographed picture taken in the photographing means (2, 21, 32, 51, 61) when the first detecting signal is provided from the detecting means (8, 23, 41) and selects the received picture received in the receiving means (4, 5) when the second detecting signal is provided from the detecting means (8, 23, 41).
Claim 3
Dependent Claim

A video phone unit in claim 1 further including: a second selecting means (25) for selecting either arbitrary pictures or the photographed picture taken in the photographing means (2, 21, 32, 51, 61) when the first or second detecting signal is provided from the detecting means (8, 23, 41) and transmitting the selected picture to the other party through the transmitting means (6, 7).
Claim 4
Dependent Claim
75 words
A video phone unit in claim 3 in which the second selecting means (25) stops transmitting the photographed picture taken in the photographing means (2, 21, 32, 51, 61) to the other party when the first detecting signal is provided from the detecting means (8, 23, 41), while the second selecting means (25) transmits the photographed picture to the other party when the second detecting signal is provided from the detecting means (8, 23, 41).
Claim 5
Dependent Claim
61 words
A video phone unit in claim 3 further including: an internal memory means (24)for memorizing in advance a prescribed picture transmitted to the other party through the transmitting means (6, 7) instead of the photographed picture taken in the photographing means (2, 21, 32, 51, 61) while the second selecting means (25) stops transmitting the photographed picture to the other party.
Claim 6
Dependent Claim
69 words
A video phone unit in claim 3 further including: an external memory means for memorizing an arbitrary picture transmitted to the other party through both an input terminal for receiving the arbitrary picture and the transmitting means (6, 7) instead of the photographed picture taken in the photographing means (2, 21, 32, 51, 61) while the second selecting means (25) stops transmitting the photographed picture to the other party.
