ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a code image recording apparatus for recording a speech entered through a microphone by printing it on a predetermined printing medium in the form of an optically readable code image.
The assignee of the present patent application has proposed a recording apparatus for recording a speech by printing it on a predetermined printing medium in the form of an optically readable code image of dot codes in EP 0,670,555 A1 (U.S. Ser. No. 08/407,018 now issued as U.S. Pat. No. 5,896,403).
FIGS. 1A and 1B
of the accompanying drawing schematically illustrate the configuration of the physical format of dot codes to be used for the proposed recording apparatus. The code pattern
1
comprises a plurality of blocks
2
arranged two-dimensionally on a side by side basis. Each block
2
by turn comprises a data area
3
, markers
4
and a block address pattern
5
.
The data area
3
contains white dots and black dots representing respective data values of “0s” and “1s” that are assigned to each block as speech data and arranged according to a predetermined format of arrangement to produce a white dot image or a black dot image. The markers
4
are black markers arranged at the four corners of the block
12
to provide a reference point for detecting each dot in the data area
3
, each of the markers
4
being formed by a certain number of consecutively arranged black dots. The block address pattern
5
is arranged between adjacently located markers
4
to make the block
2
discriminable from other blocks
2
and contains white dots and black dots representing respective data values of “0s” and “1s” that are assigned to each block as address data including an error detecting or error correcting code. The vertical and horizontal lines connecting the dots in the drawing are used for the ease of understanding and they do not exist in real code images.
A system using dot codes arranged with the above described physical format provides an advantage that the original data can be restored by rearranging the data of the blocks according to their respective addresses if all the dot codes of the data covers an area greater than the area that can be taken by the solid state image sensing device of the image reader or, differently stated, if the entire dot codes of the data cannot be picked up by a single shot, provided that the address of each of the blocks is contained in any of the images taken by the image reader. Therefore, such a dot code system can store a huge volume of data on a single sheet of paper in a manner that no known one-dimensional or two-dimensional bar code system can ever do, and as a result so that speech data can be transmitted or transported in a simple manner by means of a recording medium such as paper. Thus, the dot code system may have a wide variety of applications that are not conceivable with any known code systems.
The code image recording apparatus may be an ordinary printer or a label printer adapted to print and record optically readable dot codes continuously on label-like sheets of paper being fed also continuously along a given direction.
The use of a label printer for a code image recording apparatus is very promising because it is portable and easy to use and hence provides a broad opportunity of utilization.
However, label printers or not, known code image recording apparatuses have problems to be overcome before they get a high market value.
More specifically, with a code image recording apparatus of the type under consideration comprising a microphone for speech input, code image converting means for encoding the input speech and converting it into a code image of dot codes and a printer for printing and recording the code image obtained by the code image converting means as optically readable image contained in a single cabinet, the microphone picks up the noise emitted by the printer to adversely affect the input speech and remarkably degrade the quality of speech if the speech input operation of the microphone and the code image printing operation of the printer take place concurrently.
BRIEF SUMMARY OF THE INVENTION
In view of the above identified problem, it is therefore the object of the present invention to provide a code image recording apparatus that can minimize the degradation of the quality of the speech input through the microphone given rise to by a code image printing operation of the printer.
According to a first aspect of the present invention, there is provided a code image recording apparatus comprising:
a microphone for inputting a speech;
code image converting means for converting the speech input by the microphone into a code image of encoded data arranged according to a predetermined format;
a printer for printing the code image converted by the code image converting means on a predetermined printing medium as an optically readable image, the microphone, the code image converting means and the printer being contained in a single cabinet;
operation mode setting means for setting a speech input mode adapted to make the microphone input a speech to be converted into a code image by the code image converting means and a printing/recording mode adapted to make the printer print and record the code image converted by the code image converting means on a printing medium; and
mode selection control means for controlling the operation mode setting means so as to set only one of the above operation modes and prohibiting it to set the other operation mode.
According to a second aspect of the present invention, there is provided a code image recording apparatus comprising:
a microphone for inputting a speech;
code image converting means for converting the speech input by the microphone into a code image of encoded data arranged according to a predetermined format;
a printer for printing the code image converted by the code image converting means on a predetermined printing medium as an optically readable images, the microphone, the code image converting means and the printer being contained in a single cabinet;
operation mode setting means for setting a speech input mode adapted to make the microphone input a speech to be converted into a code image by the code image converting means and a printing/recording mode adapted to make the printer print and record the code image converted by the code image converting means on a printing medium; and
mode selection control means for prohibiting the operation mode setting means to set the printing/ recording mode if the latter has set the speech input mode.
According to a third aspect of the present invention, there is provided a code image recording apparatus comprising:
a microphone for inputting a speech;
code image converting means for converting the speech input by the microphone into a code image of encoded data arranged according to a predetermined format;
a printer for printing the code image converted by the code image converting means on a predetermined printing medium as an optically readable image, the microphone, the code image converting means and the printer being contained in a single cabinet;
operation mode setting means for setting a speech input mode adapted to make the microphone input a speech to be converted into a code image by the code image converting means and a printing/recording mode adapted to make the printer print and record the code image converted by the code image converting means on a printing medium; and
mode selection control means for prohibiting the operation mode setting means to set the speech input mode if the latter has set the printing/recording mode.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.
