Abstract: PURPOSE:To certainly and automatically separate electronic parts one by one without being damaged, by inserting and pulling-out a needle-shaped member into between the electronic part whose slide-down is suspended by a stopper and the succeeding electronic part, interlocked with the operation of the stopper. CONSTITUTION:When a movable stopper 5 rises and a needle-shaped member 10 lowers, a top IC 3a which slides-down on a chute rail 4 is stopped by a stopper 5, and the succeeding IC 3b contacts with the top IC 3a and stops.

Therefore, the sliding-down of the succeeding IC 3b is suspended and a little pushed-back. The movable stopper 5 is lowered in this state, and then only the top IC 3a is slided-down and separated. Then, the stopper 5 rises, and the needle-shaped member 10 lowers, and then IC 3b slides-down to the vacant position E where IC 3a exists before. Therefore, the electronic parts which slide-down on the chute rail can be automatically separated one by one without being damaged.

Abstract: PURPOSE:To improve evaporation efficiency and to prolong the life of a crucible of the device using the target impregnated with a metal to be evaporated into a porous high melting metal by providing a heat insulating space between the target and the crucible contg. this target. CONSTITUTION:The circular cylindrical target 4 formed by impregnating the metal 3 to be evaporated into the porous member 2 to be not deposited by evaporation is housed in, for example, the blind cylindrical copper crucible 1 opened at the upper part. The heat insulating space 5 is formed between the inside wall surface of the crucible 1 and the target 4. The member 2 to be not evaporated is irradiated with an electron beam 6 from an electron gun and the metal 3 to be evaporated is evaporated by the energy of this time. The heat conduction between the target 4 and the crucible 1 is executed by radiation as the heat insulating space 5 exists in this case and, therefore, the heat transmission loss is decreased and the evaporation efficiency is improved. Further, the life of the crucible 1 is long and the long-term operation is possible as the metal 3 does not come into contact with the inside wall of the crucible 1.

Abstract: PURPOSE:To improve reliability of a paper sheet detection means to detect existence of paper sheets by constituting it to change a working point of the paper sheet detection means at a proper point of time in accordance with an output level of a light reception part and a state of a transfer system and by enabling automatic adjustment of it against change in time series of a sensor. CONSTITUTION:Load resistance R2, R2' of a light receiving element is previously adjusted so that output of a transistor Tr1 is more than VH in the state with paper sheets, especially with semi-transparent paper sheets and it is VL in the state with no paper sheets in the state where the transistor Tr1 is switched ON. The transistor Tr1 is at first in the ON state, but when it is put in the OFF state, the load resistance of the light receiving element comes to be only R2, and the load resistance grows large and a voltage level at the time with no paper sheets is lowered. Thereby, output voltage V0 of the light receiving element at the time with no paper sheets is monitored by a CPU, and at the time of V0>=VTH, V0 approaches voltage VH due to attachment of paper dust on the light receiving element part or lowering of quantity of light of a luminous element, it is judged as paper sheet detection capacity is lowered, the load resistance of the light receiving element is changed over and the voltage level at the time with no paper sheets of V0 is lowered.
