Thereby, if the terminal end portion 5b of the guide rail 5 is expanded and contracted, the position where the straw is supplied to the binding device can be adjusted in the direction of the stem. Then, the user manually sets and operates the binding stitch position so that the set binding position set by the setting means becomes a desired binding position. Then, when the length of the waste straw changes and the stock position of the waste straw supplied to the binding device changes, the device moving actuator is automatically operated based on the information from the stock sensor, and the knocking device is ejected. It is moved in the direction of the straw culm and acts on the straw. When the position of the tapping and aligning device with respect to the binding device changes in this manner, the operating means automatically operates the rail expansion / contraction actuator to move the end side portion of the guide rail based on the position change and the binding position set by the setting means. By performing the expansion and contraction operation, the position of supplying the straw to the binding device is adjusted. That is, adjustment is performed so that the binding position by the binding device becomes the binding position set by the setting means. As a result, even if the length of the waste straw is changed, it is possible to prevent the hitting and aligning device from hitting or hitting easily.Also, the binding device is fixed at an appropriate position while the binding device is fixed.
