Title: Sorter
Inventor: HIGAKI MASAHIRO
IPC: G03G15/00
Filed: 1984-11-13
Abstract: PURPOSE:To reduce the cost and easily manage a jam, according to a method wherein the sheet conveying belt between a receiving portion and a deflecting portion is enabled to reversely rotated, so that the load of a motor is decreased. CONSTITUTION:When sorting operation is finished, the motor M1 of a deflecting portion an a conveying motor are reversely rotated at the same time. Therefore, when it is confirmed that a deflecting portion 10 is raised and returned to a home position, the reverse rotations of the conveying motor and the motor M1 are stopped at the same time. When a jam is generated in a sorter 1, the rotation of the conveying motor is stopped, and an operator turns on a switch SW at his option, and then the conveying motor is reversely rotated, and a jammed sheet S is returned to the position in which the jammed sheet can be easily removed. As described above, a cost can be reduced and jam managing operation is improved because an excess load is not loaded to the driving motor of the deflecting portion and a motor having high torque is not required.

Filed: 1990-09-12
Abstract: PURPOSE:To prevent the adherence of foreign matters and the occurrence of scratches for a surface acoustic wave SAW element in its assembling or packaging state by attaching a protecting cover right after the formation of an SAW electrode. CONSTITUTION:An SAW element which generates the deflected or modulated radiated laser light 10 is obtained by making an SAW 6 affect colinearly or coplanarly the incident laser light 9.

Title: Winning ball pay-out device and method of controlling thereof
Inventor: MIWA MINORU
IPC: A63F7/02
Filed: 1994-10-04
Abstract: PURPOSE: To enhance the freedom of setting pay-out of game balls by providing such an arrangement that a game ball run down in a row through an awarding ball passage from an awarding ball tank under the gravity, are caught by an upper sprocket on rotation so that the ball is fed through the passage to a lower sprocket which is rotated in association with the upper sprocket so that the ball runs down further. CONSTITUTION: A control circuit actuates a lever 13 in response to a game ball detecting signal from a photosensor 19 so as to cause a rack part 12 from retracting. Accordingly, a game ball B1 which has been inhibited by a hook part 12 from dropping, drops down through an awarding ball passage 2 onto a discharge port 2. At this time, the game ball B1 serves as a bearing ball so that the hook part 12 can smoothly retract, overcoming the loads of game balls B2, B3, B4. Then, the game ball B2 comes off from an upper sprocket 6 in response to a detection signal delivered from an optical sensor 18, so that the shift of the ball B2 onto a lower sprocket 7 is determined. Thus, the control part returns the lever 13 to its original position, and accordingly, the hook part 12 extends into the awarding ball passage 2 so as to inhibit the ball B2 from dropping.

IPC: G11B15/30
Filed: 1983-12-20
Abstract: PURPOSE:To simplify the constitution and to eliminate the assembling time for a reel shaft for tape recorder by forming plural engaging pieces in a body with the main body of a columnar reel shaft at the outer circumference of said reel shaft main body with a gap secured between them and thus producing the reel shaft in a single unit. CONSTITUTION:For reel shafts 2a and 2b, a flange part 9 is formed at the outer circumference of the lower edge of a columnar reel shaft main body 8 having a truncated conical form at its tip. Three elastic engaging piece 10 are protruded in the circumferential direction and equidistantly on the upper surface of the flange 9. These component parts are unified with a synthetic resin. When a cassette is loaded, the main body 8 is put into a reel hub within the cassette. At the same time, the three bars 10 are engaged with the engaging projected parts within the reel hub in the revolving direction. Thus, the revolutions of the shafts 2a and 2b are transmitted to the reel hub. When the engaging projection within the reel hub touches the top end of the piece 10, the piece 10 is deformed elastically toward the inside. Thus the engaging projection in the reel hub slips down along a sloping surface 12. During this slip-down process, the engaging projection is detached from the piece to secure 10 proper cassette loading state.
