Abstract
Abstract A picture reading apparatus is disclosed which comprises a camera which converts a picture to be read to an electric signal, a supporting member for supporting the camera movably, and a voice input unit. A control device serves to minimize the output from the voice input unit during movement of the supporting member. Thus while a mechanism for moving the camera is in operation, the output from the voice input unit is minimized to suppress the output of operational noise.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
54 words
A picture reading apparatus comprising: photoelectric conversion means for converting an image of an object to an electric signal; support means for movably supporting said photoelectric conversion means; voice input means for inputting a voice signal; and control means for reducing an output from said voice input means when said support means is moved.
Claim 2
Dependent Claim
54 words
A picture reading apparatus comprising: photoelectric conversion means for converting an image of an object to an electric signal; support means for movably supporting said photoelectric conversion means; voice input means for inputting a voice signal; and control means for reducing an output from said voice input means when said support means is moved.
Claim 3
Dependent Claim
20 words
A picture reading apparatus of claim 1, further comprising means for detecting whether or not said support means is movable.
Claim 4
Dependent Claim
23 words
A picture reading apparatus of claim 1, wherein said control means includes mean for virtually nullifying the output from said voice input means.
Claim 5
Dependent Claim
18 words
A picture reading apparatus of claim 1, wherein said voice input means is supported by said support means.
Claim 6
Dependent Claim
24 words
A picture reading apparatus of claim 1, wherein said support means includes a locking mechanism for limiting the movement of said photoelectric conversion means.
Claim 7
Dependent Claim
48 words
A picture reading apparatus of claim 5, further comprising means for detecting the unlocked state of said locking mechanism, and wherein said control means includes means for reducing the output from said voice input means in response to the detection of said unlocked state by said detecting means.
Claim 8
Dependent Claim
95 words
A picture reading apparatus comprising: an object plate on which an object to be read is placed; photoelectric conversion means, supported by a supporting member including a support section connected to said object plate, for converting an image of said object to an electric signal, said support section being extendable; first lock means for setting said support section continuously at any position in an extension thereof; second lock means for fixing said support section at a predetermined position; and unlock means for unlocking said first and second lock means simultaneously using a single operation member.
Claim 9
Dependent Claim
95 words
A picture reading apparatus comprising: an object plate on which an object to be read is placed; photoelectric conversion means, supported by a supporting member including a support section connected to said object plate, for converting an image of said object to an electric signal, said support section being extendable; first lock means for setting said support section continuously at any position in an extension thereof; second lock means for fixing said support section at a predetermined position; and unlock means for unlocking said first and second lock means simultaneously using a single operation member.
Claim 10
Dependent Claim
32 words
A picture reading apparatus of claim 7, wherein said support section includes: (a) a fixed stand fixed to said object plate; and (b) a movable stand movable relative to said fixed stand.
Claim 11
Dependent Claim
23 words
A picture reading apparatus of claim 8, wherein said first lock means includes an engagement member provided between said fixed and movable stands.
Claim 12
Dependent Claim
31 words
