In the state shown in FIG. 1, the photoelectric conversion unit Ll+L! of the optical reading device S! The digital values stored on the memory medium M are read by +L3+, and the digital values 1, 1 are read from the photoelectric conversion units L+, Lx, and Ls.
．． O is being read. This digital value 1,1. O is the photoelectric conversion unit La, L3 . LA,
This is a signal to indicate that the digital value read by . . . is the digital value of actual data. That is, all the photoelectric conversion sections located on the left side in FIG. 1 of the photoelectric conversion sections only receive the reflected light from the surface of the memory medium section, so they all output 0. In this way, when reading the presence or absence of the printing status of the recording points DIF+D, D, A, ... of each line, the output signal of the optical reading device S is transmitted to the photoelectric conversion section disposed on the left side of the photoelectric conversion section L1. output digital signal 0

This shows a case where they overlap.

Assume that the colored dots are black and the amount of light reflected from them is O, and if the amount of reflected light from the surface of the memory medium where no colored dots are printed is 100%, as can be seen from the figure, The amount of light received by the photoelectric conversion section on the left side of the photoelectric conversion section is 100%, and the amount of light received by the photoelectric conversion section is 70%.

In this case, the photoelectric conversion part L+ of 170% and 60% of light reception
, a photoelectric conversion section that outputs a digital value of 1 from the output signal of Lx and receives 90% of the amount of light.

Signal processing is performed to output a digital value of 0 from the output signal. And photoelectric conversion units La and Ls.

The output signals of LA, ... are 60% and 70% of the received light amount.

If you perform signal processing to output 0 in the case of 00%,
Photoelectric conversion section L4. Digital values of actual data are obtained from Ls, LA, .

Figure 2 (B) shows each recording point D + y+ D zy+ D

Come to the middle position of 10% of the area of the colored dot
The figure shows a case where 30% overlaps with the photoelectric conversion section on the left side and 30% overlaps with the photoelectric conversion section on the right side.

Now, as in the case of FIG. 2(A), if the amount of light reflected from the colored dots is O, and the amount of reflected light from the surface of the memory medium M on which no colored dots are printed is 100%, then FIG. As can be seen, the amount of light received by the photoelectric conversion section on the left side of the photoelectric conversion section L1 is 100%, the amount of light received by the photoelectric conversion section Lx is 90%, the amount of light received by the photoelectric conversion section Lx is 60%, and the amount of light received by the photoelectric conversion section L3 is 60%. , L-, LS, Lt, Lt, and ri are 70%, 90%, 60%, 70%, and 9, respectively.
0% and 70%.

In this case, the photoelectric conversion unit Lt with 60% and 70% of the received light amount
It outputs a digital value 1 from the output signals of and, and performs signal processing so as to output a digital value O from the output signal of the photoelectric conversion unit L4 whose received light amount is 90%. and,
The output signals of the photoelectric converters 1, 65, L, ... output 1 when the amount of light received is 60% and 70%, and output O when the amount of received light is 90% and 100%. If signal processing is performed, photoelectric conversion units Ls and Lh

ffF+... is the photoelectric conversion unit Ll, Lt, L,...
・Come to the exact middle position of 20% of the area of the colored dot.
A case is shown in which each overlaps with the left and right photoelectric conversion sections, respectively.

Now, as in the case of FIG. 2(A), if the amount of light reflected from the colored dots is 0%, and the amount of reflected light from the surface of the memory medium M on which no colored dots are printed is 100%, then As can be seen from the figure, the amount of light received by the photoelectric conversion section on the left side of the photoelectric conversion section L1 is 100%, the amount of light received by the photoelectric conversion section L1 is 80%, and the amount of light received by the photoelectric conversion section L1 is 80%. The amount of light received is 60%, and the photoelectric conversion parts Lx, La, Ls, Lb, Lt, and
The amount of light received is 80%, 80%, 60%, and 80%, respectively.
, 80%, and 80%.

In this case, if the presence or absence of printing of a colored dot at the recording point DXA is detected by the photoelectric conversion unit facing the left half of the recording point D1y, the presence or absence of printing of a colored dot at the recording point D1y can be detected by the photoelectric conversion unit facing the left half of the recording point D1y. This will be detected by the converter L1. Therefore, a digital value 1 is output from the output signal of the photoelectric conversion section that receives 180% of the light and the photoelectric conversion section Lt that receives 60% of the light, and a digital value of 0 is output from the output signal of the photoelectric conversion section that receives 80% of the light. Perform signal processing to output. Such signal processing, i.e., the same amount of received light 80
Signal processing in which one of the photoelectric conversion units L1 and L1 outputs a digital value 1 and the other L3 outputs a digital value O is performed as follows.

That is, the photoelectric conversion unit Lo located on the left side of the photoelectric conversion unit L1
Since the received light is 1tloo%, it outputs a digital value O. In this case, the photoelectric conversion section.

This means that there is no colored dot between the photoelectric conversion section L0 and the photoelectric conversion section L0 on the left side, and it is the photoelectric conversion section that receives 80% of the amount of light received by the photoelectric conversion section L1.

This is because a colored dot is printed at the recording point D+y on the right side of the image.

Also, since the digital value l is output by the photoelectric conversion unit Lt adjacent to the left side of this photoelectric conversion unit L2, the recording point D2 detected by this photoelectric conversion unit L2 is
There is a colored dot printed on y, and it can be seen that the right half of the colored dot indicates that the amount of light received by the photoelectric conversion unit L3 is 80%.

Therefore, in the case of a photoelectric conversion unit that receives 80% of the amount of light, if the photoelectric conversion unit adjacent to the left side of the photoelectric conversion unit outputs a digital value of 1, it outputs a digital value of 0,
When the photoelectric conversion section adjacent to the left side outputs a digital value of 0, signal processing is performed so as to output a digital value of 1.

Therefore, photoelectric conversion parts L4, Ls, I-b
The output signals of , . In addition, signal processing is performed to output a digital value l when the amount of received light is 100%, and when the amount of received light is 8
0% and a digital value 1 is output from the output signal of the photoelectric conversion unit placed on the left side of the photoelectric conversion unit, if signal processing is performed to output a digital value 0,

In the explanation of FIGS. 1 and 2 above, recording points D+ y+
The pitch of D zy+ D iF+ ... and the pitch of the photoelectric conversion sections L1, Lz, Ls, ... have been described as always being equal, but if the memory medium M is made of a material with large thermal expansion, If the temperature at the time of recording differs from the temperature at the time of reading, the recording point of the memory medium M will change due to reasons such as thermal expansion.

The colored dot at the recording point DI has 25% of its area on the left side facing the photoelectric conversion section L2, and the colored dot at the recording point Dty has its area on the right side 15% facing the photoelectric conversion section L2. It is assumed that there is Also, recording point D4°4. 20% of the area on the left and right sides are photoelectric conversion parts L4°4. It faces L4.7. In this case, the positions of the recording points DIy are the photoelectric conversion units LI+ and L2. This means that it is deviated slightly closer to than in the middle of . The amount of deviation is (X/4)X (25
%-20%)+(25%+15%), the offset position becomes X/32. That is, the center point of the recording point Dly is (x/2)−(X/

It can be assumed that x/32 is on the right side. Also,

It has come to a position shifted by 65x/32 from 4y°).

This recording point D4°4. is 41 counting from recording point D3V
Since it is the first one, the recording point is D 4/+ D SF+
D & y+ . . . are arranged at a pitch of x+(65x/32) x (1/401) based on the position of the recording point D zy. Therefore, it can be seen in what positional relationship each recording point, . . . , DSy+ D6a, .

The presence or absence of printed colored dots is read sequentially from left to right, so the recording point D□1. which was read just before the recording point DX which is currently being read. ．． The presence or absence of colored dots is known. Therefore, as explained in FIG. 2(C) above, the output signal of the photoelectric converter facing the recording point Dxy that is currently being read is
It is possible to calculate how much it is influenced by y. If the output signal is compensated for the above influence, the recording point D that is currently being read will be
