10. PRECAUTIONS REGARDING OUTER COVER DESIGNS
To prevent jams at the presenter discharge outlet, consider designing the casing so that recording paper does
not enter between the presenter unit and the case.
1 Gap of *1 must be a maximum of 1 mm. (See Figure 10-1)
2 The dimensions of *2 must be larger than the presenter discharge outlet (2 mm), but it should be
small enough that it does not block the paper discharge outlet.(See Figure 10-1) If it is too large,
interfering light (from the sun, etc.) will enter from outside of the apparatus from the recording
paper outlet causing the paper detectors (sensors) to mis-operate, so do not make them too large.
1) The casing for the recording paper discharge outlet should have an outlet portion established such as
*3 so that coins and clips do not fall into the casing. (See Figure 10-1)
2) Storage space for the recovery of recording paper should consider the length of the recording paper
and degree of curling to all plenty of space. It is recommended to ensure approximately 100 mm or
more space for storage depth. (See Figure 10-2)
