ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a coder 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 and reproducing the entered speech from a loudspeaker.
The assignee of the present patent application has proposed a recording apparatus for recording 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).
FIGS. 1A and 1B
of the accompanying drawings 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
in 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 matter that can be achieved by no other known one-dimensional or two-dimensional bar code system 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 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 they get a high market value.
More specifically, with a code image recording apparatus of the type under consideration comprising speech input means such as microphone for speech input, code image converting means for encoding the input speech and converting it into a code image of dot codes, a printer for printing and recording the code image obtained by the code image converting means as optically readable image and a loudspeaker for outputting the speech entered by the speech input means, that are contained in a single cabinet, the faint vibrations generated at the time of speech output from the loudspeaker can be transmitted to the printer to interfere with the operation of printing fine dots to deform all or some of the dot codes being printed and adversely affect the operation of reading the printed and recorded dot codes of the code image.
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 adverse effect of the vibrations generated at the time of speech output from the loudspeaker on the operation of printing and recording a code image.
According to a first aspect of the present invention, there is provided a code image recording apparatus comprising:
speech input means for inputting speech;
code image converting means for converting the speech input by the speech input means 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;
a loudspeaker for outputting the speech input by the speech input means, and wherein the speech input means, the code image converting means, the printer and the loudspeaker are all contained in a single cabinet;
operation mode setting (i) means for setting a speech output mode adapted to make the loudspeaker output the speech input by the speech input means, and (ii) 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 said speech output mode and said printing/recording mode and prohibiting said operation mode setting means to select the other of said modes.
According to a second aspect of the present invention, there is provided a code image recording apparatus comprising:
speech input means for inputting speech;
code image converting means for converting the speech input by the speech input means 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;
a loudspeaker for outputting the speech input by the speech input means, and wherein the speech input means, the code image converting means, the printer and the loudspeaker are all contained in a single cabinet;
operation mode setting (i) means for setting a speech output mode adapted to make the loudspeaker output the speech input by the speech input means, and (ii) 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 operation mode setting means has set the speech output mode.
According to a third aspect of the present invention, there is provided a code image recording apparatus comprising:
speech input means for inputting speech;
code image converting means for converting the speech input by the speech input means 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;
a loudspeaker for outputting the speech input by the speech input means, and wherein the speech input means, the code image converting means, the printer and the loudspeaker are all contained in a single cabinet;
operation mode setting (i) means for setting a speech output mode adapted to make the loudspeaker output the speech input by the speech input means, and (ii) 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 opera
