A color measurement apparatus includes an opening portion that is formed in an opening portion forming member arranged in a bottom portion of the apparatus and causes light arriving from a measurement target to enter inside the apparatus, a light emission portion that emits light for measurement toward the measurement target, and a shutter unit that is configured to switch between a closed state in which the opening portion is covered, and an open state in which the opening portion is open, and that has a reflection reference surface at a position facing the opening portion in the closed state as a reference of reflectance, in which the shutter unit is disposed such that the shutter unit is configured to switch to, in addition to the closed state and the open state, an exposed state in which the reflection reference surface is exposed outside the apparatus.

Color measurement apparatus

A medium feeder includes: a path blocking member configured to rotate to switch between a blocking state that blocks a feed path for a medium fed out from a tray at a position of the guide member, and an open state that opens the feed path; and a switching unit that performs switching of the path blocking member, wherein the switching unit includes a rack configured to be displaced in a feeding direction in which a medium is fed from the tray to thereby perform switching of the path blocking member, and a pinion gear that drives the rack.

Medium transport device and recording apparatus

A printer includes a printer body, a hopper, an open-and-close cover, a paper support, and a support holder. The hopper pushes paper up while supporting the paper. The open-and-close cover is able to be opened from and closed toward the printer body. The paper support is provided in such a way as to be able to be housed inside and drawn away from the open-and-close cover, and is configured to support the paper by being drawn out. The support holder supports the paper, together with the hopper and the paper support. The support holder switches between an upright orientation for being housed into the printer body and a tilted orientation for supporting the paper together with the hopper and the paper support by the opening and closing of the open-and-close cover.

Image forming apparatus

A recording apparatus includes a medium mounting section, a feed mechanism, a recording section, a housing, and a reading unit. The reading unit is provided on top of the housing and includes a document feed opening, a transport section, and a reading section. A back cover moves in tandem with a mounting tray, and moves to a closed position in which the back cover covers the opening when the mounting tray is closed and an open position in which the back cover does not prevent the mounting tray from rotating for stowage in the opening when the mounting tray is open. When in the closed position, the mounting tray covers the document feed opening of the reading unit.

Recording apparatus

A printer includes a first upper face cover and a second upper face cover. The first upper face cover is formed such that when a medium is set in a setting port, the width direction of the medium is a first direction, and the first upper face cover has a smaller dimension in the first direction than a dimension of an apparatus main body in the first direction. The first upper face cover in a closed state is included inside the second upper face cover in plan view when the second upper face cover is in a closed state. The first upper face cover and the second upper face cover both in the closed states form a shape that corresponds to an outline of an upper portion of the apparatus main body.

Of at least three drive sources provided inside a printer body, a carriage-driving motor and a transport motor are disposed on one side with respect to a center portion in a width direction that intersects a medium transport direction while a sheet-feed motor is disposed on the other side with respect to the center portion in the width direction. The battery that provides electric power to the three drive sources is disposed such that the center of gravity of the battery is on the other side with respect to the center portion in the width direction.

A printer includes an encoder scale having a reading region that is read by an encoder that detects a motion of a transport driving roller, and an anti-static unit having an anti-static brush that is in contact with the encoder scale and a base that supports the anti-static brush, wherein the anti-static brush is in contact with a region of the encoder scale other than the reading region.

A recording apparatus includes a medium container to store a medium, feeding rollers to be switched between a feeding state in which the feeding rollers are in contact with the medium and a separated state in which the feeding rollers are separated from the medium, a reversing path for reversing the medium that has been fed from the medium container, a recorder to perform recording on the medium that has been reversed by the reversing path, a back-feed path for introducing the medium that has been fed in the reverse direction from the recording region in which recording has been performed by the recorder toward the reversing path, and a nip roller configured to nip the medium within the back-feed path. At least a portion of the feeding rollers that are in the separated state overlaps the nip roller in the direction of the height of the recording apparatus.

A printer includes a first sensor configured to identify a section to be identified of a movable tray. A computer in the printer drives a motor in a direction where the movable tray heads to a supplying position and stops driving the motor when an impact, where the drive load on the motor exceeds a threshold due to the movable tray hitting a separating mechanism which is at the supplying position, is detected. In addition, the computer drives the motor in a direction where the movable tray heads to a setting position, and stops driving the motor and arranges the movable tray at the setting position when the first sensor is on due to the section to be identified being identified.

Printing apparatus

A feeder unit includes: a first tray that keeps a storage position in which the first tray is stored within the base portion and an operation position, and is provided at one end of a feeding path of a medium so as to place the medium thereon; a cover member that is openably and closeably provided to cover the first tray in the storage position when being closed or uncover the first tray when being open; and a first power transmitter that transmits power to open and close the cover member to the first tray, and the first power transmitter is configured so as to displace the first tray to the operation position with the displacement of the cover member when the cover member is switched to an open-state, and to the storage position with the displacement of the cover member when the cover member is switched to a closed-state.

Feeder unit

A feeding device includes: a hopper, adapted to support a medium; a feeder, operable to feed the medium in a first direction; a separator, operable to nip the medium with the feeder at a nip point; and a guide, having a guide surface which guides the medium in the first direction and is provided with a recessed portion at a downstream side of the nip point in the first direction.

Feeding device

A liquid ejection head is operable to eject a liquid droplet toward a target position. A transporter feeds a first target medium toward the target position in a first direction. An ejector ejects the first target medium to the outside of the apparatus. The ejector includes a first roller and a second roller adapted to nip the first target medium transported from the target position in the first direction. A guide member is disposed at a position closer to the outside of the apparatus than the ejector, and has a guide face along which a tray member on which a second target medium is mounted is fed toward the target position in a second direction which is opposite to the first direction. The guide member is pivotable between a first position for closing the guide face and a second position for opening the guide face to support the tray member.
