A first temperature sensor detects (53) a first temperature of a region in a heating device (52). A second temperature sensor (54) detects a second temperature of a portion of the heating device (52) between one end, and an end of the region on the side of the one end. A sheet sensor (55) detects a medium passing a position in a nip region corresponding to a portion of the heating device (52) between the other end, and the other end of the region on the side of the other end of the heating device (52). A controller (100) starts successive transport of the medium at a first number. Upon deciding that a temperature difference is smaller than a first threshold, and that the medium has not been detected, the controller (100) changes the number of sheets of the successive transport to a second number, fewer than the first number.

A document sheet (101) is put on a feeding tray (11). A lifting device (22) lifts and lowers the feeding tray. A feeding roller (12a) receives contact with the document sheet and feeds the document sheet. A sensor (42) detects that the document sheet on the feeding tray makes contact with the feeding roller. A controller (51) controls the lifting device and thereby controls a height position of the feeding tray, and performs feeding and transportation of the document sheet using the feeding roller when the sensor detects that the document sheet makes contact with the feeding roller. Further, when the feeding and transportation of the document sheet is failed, the controller performs additional lifting of the feeding tray by a specific retry distance using the lifting device and thereafter performs feeding and transportation of the document sheet again. Here, the retry distance is set on the basis of a type of the document sheet.

An electronic apparatus includes a controller circuit board, and an internal device configured to be controlled by the controller circuit board. Further, the controller circuit board includes a memory module and a processor configured to transmit and receive a transmission signal to/from the memory module and thereby perform read and write of data. The processor includes a first input/output circuit configured to transmit and receive the transmission signal, and the memory module includes a second input/output circuit configured to transmit and receive the transmission signal. If the read or the write is not performed properly due to waveform distortion of the transmission signal, the processor changes an output condition or an input condition of the transmission signal in at least one of the first and second input/output circuits such that the waveform distortion does not cross a level detection threshold value of the transmission signal.

A punching device (PU) includes a punching member (1), a pin (2) that protrudes one end portion (21) and the other end portion (22) thereof in the second direction (D2) from the punching member (1), a holder (3) that is coupled to the one end portion (21) and the other end portion (22), and a guide (4) that accommodates the punching member (1). The guide (4) has pin insertion holes (40). The one end portion (21) and the other end portion (22) protrude to outside the guide (4) through the pin insertion holes (4). The holder (3) has a fitting hole (30), and the guide (4) is fitted into the fitting hole (30) such that the holder (3) is held so as to be movable along an outer circumferential surface of the guide (4). The fitting hole (30) has a recessed portion (31) that is recessed outward in a radial direction. The guide (4) has a protruding portion (41) that is positioned within the recessed portion (31).

A fixing device (13) includes: a heat roller (31); a heating device (52) disposed inside the heat roller (31) to heat the heat roller (31); a pressure roller (32) opposed to the heat roller (31) and forming, together with the heat roller (31), a nip (N) where a recording medium (P) to be subjected to fixing processing is to be passed through; a conveyance guide (61) that guides the recording medium (P) to the nip (N) and is provided with a gap (G) from the pressure roller (32) in a direction in which the conveyance guide (61) guides the recording medium (P), and an air blower (71) disposed in a region located on the pressure roller (32) side of the conveyance guide (61) in a direction of alignment of the heat roller 4520251207 (31) and the pressure roller (32) to blow air toward the heat roller (31) through the gap (G).

An optical scanning device includes a polygon mirror, a mirror cover, and a position sensing portion. The polygon mirror rotates about a rotation axis extending along the top-bottom direction to reflect laser light and scans the circumferential surface of an image carrying member along a main scanning direction. The mirror cover covers the polygon mirror. The position sensing portion senses the rotation position of the polygon mirror. The mirror cover has an opening part. The opening part penetrates, along the radial direction, part of a circumferential wall part covering the polygon mirror from radially outward. The position sensing portion is disposed on the mirror cover with at least part of it disposed in the opening part.

The inkjet recording apparatus (100) includes a head unit (HU), a cleaning member (2), and a container member (3) which, by being pressed from above to below, is displaced from a first position to a second position, the container member (3) functioning in the second position to supply the cleaning member (2) with a detergent. The container member (3) includes a containing part (31) for containing the detergent, and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The head unit (HU) has a head base (11), and the head base (11) presses the base part (32) from above to below without making contact with the containing part (31) so that the container member (3) is displaced from the first position to the second position.

The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), and a container member (3). The container member (3) includes a containing part (31) which has an upwardly opening recessed area (310) and in which detergent supplied from above is contained in the recessed area (310), and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The containing part (31) has a discharge hole (311) extending through the recessed area (310) in the up/down direction, and supplies the cleaning member (2) with the detergent flowing out downward from the discharge hole (311). An upper surface (32S) of the base part (32) is higher in liquid repellency to the detergent than an upper surface (31S) of the containing part (31).

The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), a container member (3) which, by being pressed from above to below, is displaced from a first position to a second position and which, while in the second position, accepts supply of detergent, and a supply member (5) which is placed above the container member (3) to supply the container member (3) with the detergent. The container member (3) includes a containing part (31) for accepting supply of the detergent, and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The supply member (5) presses the base part (32) from above to below without making contact with the containing part (31) so that the container member (3) is displaced from the first position to the second position.

A device registration system (40) allows an electronic device (60) to be registered into an application providing system (20) that provides an application for use by the electronic device (60). When receiving from the electronic device (60) a request to register the electronic device (60) into the application providing system (20), the device registration system (40) allows the application providing system (20) to create a tenant in association with which the electronic device (60) as a source of the request is to be registered and allows the application providing system (20) to register the electronic device (60) as the source of the request in association with the tenant created by the application providing system (20).
