An image reading device includes a motor, a reading sectionthat reads an image on a medium, a first transporting rollerthat transports the medium in a transport direction F by driving force of the motor and that is provided upstream of the reading section in the transport direction, a second transporting rollerthat transports the medium in the transport direction by driving force of the motor and that is provided downstream of the reading section in the transport direction, and a measuring section, using an encoder sensor, configured to measure the rotational position of an encoder scale, wherein the encoder scaleis provided on a rotation shaftof the second transporting roller

Image reading device having measuring section with encoder

A medium transport apparatus includes a controller that determines how many transport roller pairs disposed on a medium transport route are transporting a medium, based on detection information from detectors disposed in relation to respective transport roller pairs. Then, the controller sets a threshold to a larger value as a larger number of transport roller pairs are transporting the medium and sets the threshold to a lower value as a smaller number of transport roller pairs are transporting the medium.

Medium transport apparatus, image read apparatus, jam detection method, and storage medium

A battery mount portion includes a recessed portion into which a portion of a battery enters, a coupling terminal provided inside the recessed portion and configured to be electrically coupled to the battery, and a covering portion that covers the coupling terminal and that constitutes a portion of the housing. In a state in which the battery is unmounted, a cover that covers an area in the battery mount portion other than the covering portion is detachably attachable, and a portion where the cover and the housing overlap each other in a depth direction of the recessed portion is located outside a path of a liquid heading towards the coupling terminal after entering the recessed portion through a portion where the cover and the covering portion oppose each other.

Recording apparatus

A first transport roller that is positioned upstream of a reading member and that applies sending force to an original, a second transport roller that is positioned downstream of the reading member and that applies sending force to the original. A first transporting mode is included in a plurality of transporting modes executable by a control member. The first transporting mode includes a period in which a largest set velocity value in transporting the original while in a first state in which reading is performed while the original receives sending force from, among the first transport roller and the second transport roller, the first transport roller alone is set higher than a largest set velocity value in transporting the original while in a second state in which reading is performed while the original receives sending force from both the first transport roller and the second transport roller.
