PURPOSE:To take out tablets by a necessary number by detecting the presence of tablets in plural tablet pits installed to a shifting plate by means of a photoelectric conversion element. CONSTITUTION:Plural tablet pits 4 are installed to a shifting plate 3 and a photoreceptor cylinder 7 equipped with a photoelectric conversion element 8 is obliquely installed so that the photoreceptor cylinder 7 can face to each tablet pit 4. When tablets (a) supplied from a tablet hopper 2 are put in the pits 4, the photoelectric conversion element 8 detects this fact. When it is detected that the tablets (a) are put in the pits 4, an entry opening and closing plate 10 is opened and the tablets (a) in each tablet pit 4 falls onto a tablet receiving device 9. When all the tablet pits 4 are not filled with the tablets, the photoreceptor cylinder 7 senses light and the opening and closing plate 10 is not opened. Therefore, tablets can be taken out by a necessary number. |
