Abstract
Abstract A manual sweeping apparatus having a housing, an image sensor, a printer, and a memory. As the housing is manually swept across an original, while keeping the housing in contact with the original, information read by the image sensor is written into the memory. Thereafter, as the housing is manually moved across a piece of recording paper, while keeping the housing in contact with the paper, the information is read out from the memory and subsequently printed on the paper. During the data-reading operation, the apparatus detects and indicates whether or not any unwritten memory area exists in the memory. During the data-printing operation, the apparatus detects said indicates whether or not any items of data to be printed are stored in the memory.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
438 words
A manual sweeping apparatus including a manually manipulatable housing, said housing comprising: input means for producing image information signals while said housing is manually swept across a material having thereon image information to be copied, said image information signals corresponding to said image to be copied; memory means for storing the image information signals derived from said input means; printing means for printing image information on a printing medium while said housing is manually swept across said printing medium; position detecting means for detecting the relative position of said housing while said housing is being swept across either of said material and said printing medium, and for producing a position signal every time said housing is swept over a predetermined distance, said position signal representing the position of said housing with respect to either of said material and said printing medium; control means for controlling said printing means in synchronism with the position signal produced by said position-detecting means, for causing said printing means to print image information on said printing medium, the image information printed on said printing medium corresponding to said image information on said material to be copied; addressing means for addressing an area of said memory means in response to a position signal produced by said position-detecting means, when an image information signal from said input means is written in an addressed area of said memory means, and for addressing an area of said memory means before the position signal produced by said position-detecting means, when said image information signal is read out from said memory means and supplied to said printing means, so that image information is printed on said printing medium in correspondence with the signal produced by said position-detecting means; first detecting means for detecting whether an address value which is addressed by said addressing means, when an image information signal from said input means is written in the addressed area of said memory means, coincides with a predetermined address value; address storage means for storing the address value which is finally addressed by said addressing means while an image information signal from said input means is written in the addressed area of said memory means; second detecting means for detecting whether the address value which is addressed by said addressing means, when said image information signal is read out from said memory means and supplied to said printing means, coincides with the address value stored in said address storage means; and informing means for informing a user of the condition of said memory means in accordance with the results obtained by said first detecting means and said second detecting means.
Claim 2
Dependent Claim
438 words
A manual sweeping apparatus including a manually manipulatable housing, said housing comprising: input means for producing image information signals while said housing is manually swept across a material having thereon image information to be copied, said image information signals corresponding to said image to be copied; memory means for storing the image information signals derived from said input means; printing means for printing image information on a printing medium while said housing is manually swept across said printing medium; position detecting means for detecting the relative position of said housing while said housing is being swept across either of said material and said printing medium, and for producing a position signal every time said housing is swept over a predetermined distance, said position signal representing the position of said housing with respect to either of said material and said printing medium; control means for controlling said printing means in synchronism with the position signal produced by said position-detecting means, for causing said printing means to print image information on said printing medium, the image information printed on said printing medium corresponding to said image information on said material to be copied; addressing means for addressing an area of said memory means in response to a position signal produced by said position-detecting means, when an image information signal from said input means is written in an addressed area of said memory means, and for addressing an area of said memory means before the position signal produced by said position-detecting means, when said image information signal is read out from said memory means and supplied to said printing means, so that image information is printed on said printing medium in correspondence with the signal produced by said position-detecting means; first detecting means for detecting whether an address value which is addressed by said addressing means, when an image information signal from said input means is written in the addressed area of said memory means, coincides with a predetermined address value; address storage means for storing the address value which is finally addressed by said addressing means while an image information signal from said input means is written in the addressed area of said memory means; second detecting means for detecting whether the address value which is addressed by said addressing means, when said image information signal is read out from said memory means and supplied to said printing means, coincides with the address value stored in said address storage means; and informing means for informing a user of the condition of said memory means in accordance with the results obtained by said first detecting means and said second detecting means.
Claim 3
Dependent Claim
37 words
The manual sweeping apparatus of claim 1, wherein said first detecting means includes means for detecting whether or not the address value output from said addressing means coincides with a last address value of said memory means.
Claim 4
Dependent Claim
45 words
The manual sweeping apparatus of claim 2, wherein said first detecting means includes means for detecting whether or not the address value output from said addressing means coincides with a specified address value existing between a first and last address value of said memory means.
Claim 5
Dependent Claim
36 words
The manual sweeping apparatus of claim 3, wherein said informing means includes a light-emitting diode; and drive means for driving said light-emitting diode in accordance with the results of detection obtained by said first detecting means.
Claim 6
Dependent Claim
132 words
The manual sweeping apparatus of claim 3, wherein said informing means includes: display means; means for turning on said display means continuously until said first detecting means detects that an address value output from said addressing means coincides with a specified address value existing between first and last address values of said memory means; means for repeatedly turning on and off said display means after said first detecting means detects that an address value output from said addressing means coincides with a specified address value existing between a first and last address value of said memory means; and means for turning off said display means at a time when said first detecting means detects that an address value output from said addressing means coincides with a last address of said memory means.
