Title: Power tool
Inventor: WATANABE SHOTA
IPC: B25F5/00
Filed: 2019-10-28
Abstract: To provide a power tool configured so that a state of friction of a clutch mechanism can be monitored without disassembling the mechanism.SOLUTION: In an electric driver 1, a clutch mechanism 22 is arranged between a planetary gear mechanism 20 connected to a rotary driving shaft 18 of an electric motor 12 and an output shaft 16 which is mounted with a driver bit. When loads more than predetermined maximum torque acts on the clutch mechanism 22, a spherical engagement member 68 is displaced together with a displacing member 70 in a direction of a rotation axis line R by a columnar engagement member 60. This can release engagement in a rotating direction of the columnar engagement member 60 with the spherical engagement member 68, so that transmission of rotation torque is released. When the transmission of the rotation torque is released, a sensor pin 80 enters a space between a light casting part and a light receiving part 26a of a photoelectric sensor 26 for a brake, so that output values of the photoelectric sensor 26 for a brake increases. A calculating part 30 determines a state of friction of the clutch mechanism 22 on the basis of the output values.SELECTED DRAWING: Figure 3

Filed: 2019-11-22
Abstract: To provide an image forming apparatus which solves a problem in which bookbinding processing may be stopped during paper feed instructions after starting cut processing of binding members in ring bookbinding processing which performs cut processing of the ring-shaped binding members prior to the start of sheet printing, and in that case, the binding members which are already cut and printing papers need to be removed by a user, so subsequent jobs cannot be printed until the processing is complete, thereby reducing productivity, and by performing the binding processing when the binding processing during the paper feed instructions is stopped after starting the cut processing of the binding members, it is considered that labor for removing the binding members which are already cut and the printing papers is saved, thereby preventing the reduction in the productivity, but at this time, an unfinished item on which bookbinding processing is stopped is mixed with a product on which the bookbinding is performed, so that it is necessary to sort out the unfinished item being mixed in a post-process, thereby wasting time.SOLUTION: When bookbinding processing is stopped during paper feed instructions after cut processing of binding members, bookbinding is carried out with a binding volume which is different from the binding volume for bookbinding when paper feed is completed to the last.SELECTED DRAWING: Figure 12
