[0035] figure 1 is an explanatory view of the structure of the image forming apparatus. figure 2 is an explanatory view of the structure of the sheet information detection apparatus according to the first embodiment of the present invention. Figures 3A to 3D is an explanatory view showing a collision process of moving members. Figure 4 is a graphical representation of the results detected by the motion detector. Figure 5 is a flowchart showing the operation of the sheet information detection device.

[0036] Such as figure 1 As shown, the image forming apparatus 300 is a color copier for performing image formation on a sheet P by an image formation processing section 340 . The reading unit 311 reads image information of a color original 312 . The read information is converted into color signals corresponding to four colors of toners (cyan, magenta, yellow, and black).

[0101] Figure 6 is a flowchart of the control of the sheet processing apparatus according to the second embodiment of the present invention. Figure 7 It is a table for outputting sheet information using the measurement unit and piezoelectric element. In the second embodiment of the present invention, it will be described in reference figure 2 and Figure 4 Control in a case where the sheet information detection apparatus 100 described above is installed in a sheet processing apparatus other than the image forming apparatus 300 .

[0102] First, the sheet processing apparatus starts a sheet processing operation to start conveying the sheet (S21). Starting a sheet processing operation is performed by a user (operator) of the sheet processing apparatus pressing a start button on the apparatus main body, by sending a processing instruction from a peripheral device such as an external computer or a camera connected thereto, or the like.

[0120] Figure 8 is an exemplary view of the structure of a sheet information detection apparatus according to a third embodiment of the present invention. The sheet information detection apparatus 200 according to the third embodiment of the present invention includes as its main components: a moving member 31 for colliding with the sheet; an acceleration unit for making the moving member 31 have a predetermined speed; a supporting member for the sheet; and a measuring unit for measuring the movement of the moving member 31 . In the third embodiment of the present invention, the moving member 31 is allowed to collide with the sheet through a rotational motion in which the moving member 31 is allowed to swing about the support 33 . Furthermore, for the measurement section 47, a transmission optical sensor that is less expensive than the laser Doppler velocimeter used in the first embodiment is employed. The measurement section 47 has a structure in which the light shielding ...

Abstract

A motion member (1) urged by an application spring (4) is made to collide with a surface of a sheet material supported by a support member (14) so as to be deflectable and deformable. The velocity of the motion member (1) during the collision process is detected every second by a measuring portion (17) of a laser Doppler velocimeter. A control circuit (121) measures the velocity of the motion member (1) immediately before the collision of the motion member (1) with the sheet material, the time period of deflection deformation until the sheet material collides with an opposing member (15), and the time period of compression deformation after the collision of the sheet material with the opposing member (15), and outputs a result thereof as sheet material information to a control portion (120). The timing at which the sheet material collides with the opposing member (15) is detected by an output of a piezoelectric element (16) connected to the opposing member (15).

Description

technical field [0001] The present invention relates to a sheet information detection device that allows a moving member to collide with a sheet to generate an output that can identify the sheet, and more particularly, the present invention relates to a device for detecting impact mechanism. Furthermore, the present invention relates to a sheet processing apparatus and a sheet information detection method. Background technique [0002] In recent years, in the technical field of sheet processing apparatuses typified by image forming apparatuses such as LBPs, copiers, and inkjet printers, the types of sheets to be processed have become diversified, and the The use environment and users have also become diverse. As for the image forming apparatuses involved, there is an increasing need for quality improvement (higher image quality, faster processing speed, etc.) for such a variety of sheets. On the other hand, with diversification of sheets and diversification of processing ...
