An image reading apparatus includes: a movable body configured to illuminate a document with light; and an apparatus body configured to wirelessly transmit power to the movable body, wherein the movable body includes receiver coils, and a feed circuit in which the receiver coils uses receiving power to supply power to a load, the apparatus body includes transmitter coils placed along a track of the receiver coils, the transmitter coils and the receiver coils are placed such that power supply efficiency of any receiver coil with the transmitter coil placed along the track of the receiver coil fluctuates, and power supply efficiency related to one receiver coil increases at a position where power supply efficiency related to the other receiver coil drops, and the feed circuit supplies power sequentially using the receiving power of the receiver coil whose power supply efficiency is increased to highest among the receiver coils.

A support device is applied to support a contact image sensor of an image capture apparatus, which includes a guide rod. The support device includes a slide sleeve and an elastic rod. The slide sleeve, which has a groove, is movably disposed on the guide rod, and a portion of the guide rod is accommodated within the groove. The elastic rod is disposed on the slide sleeve to directly support the contact image sensor. The elastic rod abuts against the contact image sensor, so that the contact image sensor is pushed upwardly, and the contact image sensor is stably kept in the same direction while the slide sleeve is slid on the guide rod. Therefore, the entirety of the support device can achieve the advantages of stably supporting the contact image sensor in balance without using any sliding bracket.

According to one embodiment, an image reading apparatus includes a light emitting unit, a first carriage, a first photoelectric conversion unit, a first lens, and a second carriage. The light emitting unit irradiates a reading object with light. The first carriage includes a first optical member for guiding reflected light from the reading object. The first carriage is movable in a sub-scanning direction along the reading object. The first photoelectric conversion unit receives the reflected light from the reading object guided through the first optical member and outputs an image signal. The first lens is disposed on an optical path of the reflected light between the first optical member and the first photoelectric conversion unit, and images the reflected light from the reading object on the first photoelectric conversion unit. The second carriage is movable in a main scanning direction orthogonal to the sub-scanning direction along the reading object with respect to the first carriage. The second carriage includes a second optical member for guiding the reflected light from the reading object, a second photoelectric conversion unit that receives the reflected light from the reading object guided through the second optical member to output an image signal, and a second lens that is disposed on an optical path of the reflected light between the second optical member and the second photoelectric conversion unit and images the reflected light from the reading object on the second photoelectric conversion unit at a magnification different from the first lens.

A mechanism for supporting a traveling body includes a traveling body which reciprocates and shifts, a track member extending in a direction in which the traveling body shifts, a track surface provided in the track member to slide the traveling body, a drive section that drives the traveling body, and a slide member provided in the traveling body to support the traveling body slidably via a lubricant between the track surface and the slide member. The slide member includes a slide contact portion that slides on the track surface, a slide barrier portion provided on at least one side of the slide contact portion along a slide direction of the slide contact portion, and a guide portion which scrapes the lubricant in association with sliding of the slide contact portion, and guides the lubricant to between the slide contact portion and the slide barrier portion.

A guide mechanism guides a carriage from a first position to a second position in a sub scanning direction, guides the carriage from the second position to a third position that is different, in a main scanning direction, from the second position, guides the carriage from the third position to a fourth position in the sub scanning direction, and guides the carriage from the fourth position to the first position. A first interval maintaining portion maintains a first interval between the carriage and a platen glass when the carriage moves in a first driving direction in a scan range in the sub scanning direction. A second interval maintaining portion maintains a second interval between the carriage and the platen glass when the carriage moves in a second driving direction in the scan range, the second interval being different from the first interval.

An image reading apparatus, including: a guide rail configured to guide an image reading unit; and a fixing portion having configured to fix the guide rail with an adhesive.

Example implementations relate to a scan carriage of a print apparatus. In some examples, a system may include a print carriage to transit across a print zone of the print apparatus and a scan carriage selectably attachable to the print carriage to transit across the print zone of the print apparatus.

A guide mechanism guides a carriage from a first position to a second position in a sub scanning direction, guides the carriage from the second position to a third position that is different, in a main scanning direction, from the second position, guides the carriage from the third position to a fourth position in the sub scanning direction, and guides the carriage from the fourth position to the first position. A first interval maintaining portion maintains a first interval between the carriage and a platen glass when the carriage moves in a first driving direction in a scan range in the sub scanning direction. A second interval maintaining portion maintains a second interval between the carriage and the platen glass when the carriage moves in a second driving direction in the scan range, the second interval being different from the first interval.

An image scanning unit an image forming apparatus having the same to scan an image recorded on a document. The image scanning unit includes: a transparent window on which a document to be scanned is laid; an image sensor running straightly under the transparent window for capturing an image recorded on the document, a unit for driving the image sensor; a guide shaft for guiding the straight movement of the image sensor; and an image sensor carrier connected to the driving unit and the guide shaft for straightly moving the image sensor along the guide shaft when the driving unit operates. The image sensor carrier has an image sensor mounting surface on which the image sensor is mounted, and a guide shaft holder integrally formed with the image sensor mounting surface and mounted on the guide shaft.

An image reading device includes an image reading unit that reads an image while moving in a sub-scanning direction, a casing that houses the image reading unit, a guiding member that is movable relative to the casing in the sub-scanning direction and guides the casing in the sub-scanning direction, and an endless member to which the casing is fixed and that endlessly travels between a starting position and a terminal position in the sub-scanning direction.
