The base body is substantially rectangular-parallelepiped-shaped and includes a pair of principal faces that are opposite to each other, a pair of side faces that are opposite to each other and adjacent to the principal faces, and two end faces that are opposite to each other and adjacent to the principal and side faces. Two extended sections extend from respective ones of two extending points on an outer periphery of the wound section. The two extended sections include respective transition portions and respective exposed portions, the transition portions connect the extending points to exposed points exposed on the two end faces of the base body, and the exposed portions are exposed on the end faces.

  • Publication number: 20240059520
    Abstract: A post-processing unit includes a stapler, a driving section, and a controller. The stapler is moved in a Y direction and executes a stapling process on a paper sheet. The driving section moves the stapler in the Y direction. The controller controls an operation of the stapler and an operation of the driving section. The controller executes first control to supply a set current or a set voltage to the driving section, second control to supply, to the driving section, the same supply current as the set current or the same supply voltage as the set voltage, and third control to stop the supply of the supply current or the supply voltage. When the stapler executes the stapling process a plurality of times, the controller repeatedly executes the second control and the third control and causes the stapler to execute the stapling process during the execution of the second control.

  • Publication number: 20230126048
    Abstract: A controller can acquire, as information of a recording device, first information that can determine that a recording type of the recording device is an ink-jet type, and second information that can determine the recording type of the recording device is a laser type. The controller acquires the information of the recording device, performs the post-processing based on a first setting when the information of the recording device includes the first information capable of determining that the recording type is the ink-jet type, and performs the control of the post-processing based on a second setting different from the first setting when the information of the recording device includes the second information capable of determining that the recording type is the laser type.
