The present invention relates to a hand-operated and foot-operated knapsack-type sprayer. The knapsack-type sprayer includes a hand-operated lever (18) operating through a leverage effect. The hand-operated lever (18) mounted on the bottom end of a rod (15) is connected with an operating piece (16) assembled with a connection part (11) through a hinge at a bottom frame of a tank (10). The operating piece (16) includes a &sup shape groove (16&prime) and a long hole (16&prime&prime) which are formed on the top end thereof so that the hand-operated lever (18) is assembled with the long hole (16&prime&prime) by a hinge. The hand-operated lever (18&prime) also includes a projection (18&prime) formed thereon in order to be inserted in the &sup shape groove (16&prime). A support part (21) is formed at a top side of the tank (10). A foot-operated lever (23) is installed at the top end of the support part (21). The foot-operated lever (23) includes a pressurizing rod (22) for pressurizing a pump (13). A connection string (24) for the connection with the user&primes foot is connected with the foot-operated lever (23). The foot-operated lever (23) is formed to be restored through a spring (25). Accordingly, the pump (13) can be compressed by hand or by foot. When a user with the knapsack-type sprayer on his/her back operates the pump while walking, he/she can naturally compress the tank while walking. The user can also operate the pump by using the hand-operated lever with his/her hand. Thus, a user can select a more convenient technique for himself/herself so that reliability is maximized.COPYRIGHT KIPO 2014본 발명은 수동 및 족동 겸용 등짐분무기에 관한 것이다.구성에 있어서, 지렛대방식으로 작동하는 수동레버(18)가 구비된 수동식 등짐분무기에 있어서, 로드(15) 하단에 장착된 수동레버(18)는 탱크(10) 하부 프레임의 연결부(11)에 힌지 조립하여서 된 작동편(16)에 연결하되, 상기 작동편(16)은 선단에 ⊃형 홈(16)과 장공(16")을 형성하여 상기 장공(16")에 수동레버(18)가 힌지 조립되고, 또 수동레버(18)에는 상기 ⊃형 홈(16)에 끼워지도록 돌부(18)를 형성하며,탱크(10) 상부 일 측에 지지부(21)를 형성하되, 상기 지지부(21) 상단에 펌프(13)를 가압하는 가압로드(22)가 구비된 족동레버(23)를 설치하고, 상기 족동레버(23) 끝
