Further, the B direction is a direction substantially parallel to the Y direction in a state where the component supply device 200 is attached to the component mounting device 100.

<Configuration of device body>
As shown in FIG. 3, the parts supply device 200 includes a device main body 201 (parts supply device main body). The apparatus main body 201 sends the component supply tape T supplied from the reel R to the component supply position Pb (component holding position, component suction position). The reel R has a substantially circular shape. A component supply tape T is wound around the axis Ra of the reel R.

The apparatus main body 201 includes a tape feeding mechanism 211 for feeding the component supply tape T. The tape feeding mechanism 211 is configured to feed the component supply tape T along the tape passage 212 in the feeding direction (approximately B1 direction). The tape passage 212 is a passage through which the component supply tape T formed in the apparatus main body 201 passes. The tape passage 212 includes a first passage 212a through which the component supply tape T of the preceding reel R passes, and a second passage 212b through which the component supply tape T of the succeeding reel R passes.

The sprockets 211a and 211b are arranged in the third passage 212c of the tape passage 212. By feeding the component supply tape T, the sprockets 211a and 211b send the component E stored in the component supply tape T to the component supply position Pb on the third passage 212c of the tape passage 212.

The drive motor 211c is a motor that rotates the sprockets 211a and 211b. The drive motor 211c is connected to the sprockets 211a and 211b by a drive force transmission mechanism 211d that transmits the driving force of the drive motor 211c to the sprockets 211a and 211b. The sprockets 211a and 211b are synchronously driven by a single drive motor 211c. The driving force transmission mechanism 211d is, for example, a belt-pulley mechanism.

Further, the apparatus main body 201 includes a first tape detection unit 213a, a second tape detection unit 213b, and a third tape detection unit 213c for detecting the component supply tape T in the tape passage 212. The first tape detection unit 213a is arranged in the third passage 212c of the tape passage 212. The first tape detection unit 213a detects the component supply tape T in the third passage 212c of the tape passage 212. The second tape detection unit 213b is arranged in the first passage 212a of the tape passage 212. The second tape detection unit 213b detects the component supply tape T of the preceding reel R in the first passage 212a of the tape passage 212. The third tape detection unit 213c is arranged in the second passage 212b of the tape passage 212. The third tape detection unit 213c detects the component supply tape T of the subsequent reel R in the second passage 212b of the tape passage 212.

The first tape detection unit 213a, the second tape detection unit 213b, and the third tape detection unit 213c are, for example, sensors that indicate two detection values of on / off. In this case, the first tape detection unit 213a, the second tape detection unit 213b, and the third tape detection unit 213c detect that the component supply tape T is present when the detection value is on. Further, the first tape detection unit 213a, the second tape detection unit 213b, and the third tape detection unit 213c detect that there is no component supply tape T when the detection value is off.

Further, the apparatus main body 201 includes a feeder control unit 214 which is a control circuit for controlling the operation of the component supply apparatus 200. The feeder control unit 214 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The feeder control unit 214 sends the component supply tape T based on the control signal of the machine control unit 7, the detection results of the first tape detection unit 213a, the second tape detection unit 213b, the third tape detection unit 213c, and the like. It is configured to provide control.
