A reader includes a smartphone configured to read information from an image of a symbol included in a photographed image created by a camera module, and a unit attached to the smartphone. The unit includes a semiconductor laser to display a marker in a photographing range of the camera module. A user simply adjusts the orientation of the reader so that the marker overlaps on the symbol for reading processing of the smartphone, whereby information can be read from the symbol.

A reading device includes a housing, an imaging unit, a reading lighting unit, a guiding unit, and a guiding lighting unit. The housing has an opening covered with a transparent opening cover. An imaging unit is disposed inside the housing. The reading lighting unit illuminates the opening cover from inside the housing. The guiding unit is provided on the same plane as the opening cover at a position separated from the opening cover. The guiding lighting unit emits light from the guiding unit to the outside of the housing.

Scanner, in particular a back-of-hand scanner, with a holder, which essentially consists of a two-part housing with an integrated scanner and further assemblies for data transmission, with at least two commercially available, two-part or four-part push buttons being arranged on the housing of the scanner, which consist of a lower part and an upper part, which can be brought into operative engagement, the upper part of the respective push button on the underside of the housing of the scanner and the lower part of the respective push button are provided on a holder/fastening option for the scanner, characterized in that the push buttons (6) are made electrically conductive material and are designed as electrical interface contacts, on the one hand the upper parts (6) of the push buttons (6) of the scanner (1) have electrical connecting elements that connect to the additional electrical/electronic assemblies in the housing (2) of the scanner (1), while on the other hand lower parts (6) of the push buttons 6 of the holder (7) are equipped with electrical connecting elements (9) which lead to the additional electrical/electronic assemblies in or on the holder (7).

An image forming device includes a CPU. The CPU causes an image reader to collectively read a plurality of documents placed in each divided area of a document placement table and acquire individual images according to a user operation. Furthermore, the CPU generates, for each divided area, an image file that includes the image. In addition, if document reading is executed in a state where a document is placed in an inappropriate position, a notification screen for notifying the user that the document is not appropriately placed is displayed on a display before the image file data is generated.

Portable devices for capturing images of a surface of a building material and associated methods are disclosed. In some embodiments, the portable device includes (i) a housing, (ii) an image sensor positioned in the housing and configured to capture images of the surface at multiple time points when the housing is moved along a trajectory on the surface; (iii) a lighting component configured to illuminate the surface; (iv) an encoder configured to measure a distance travelled by the housing; and (v) a controller communicably coupled to the image sensor and the encoder. The controller instructs the image sensor to capture the images of the surface at least partially based on the measured distance travelled by the housing.

A communication terminal communicates with an image forming apparatus to be moved on a medium to perform image formation. The communication terminal includes a display and circuitry configured to receive a notification from the image forming apparatus and to display a preview of an image to be formed by the image forming apparatus. The circuitry is further configured to distinguish, on the preview, one of a plurality of lines included in the image to be formed from a rest of the plurality of lines in accordance with a content of the notification and display operation aiding information for aiding an operation of the image forming apparatus in accordance with the content of the notification.

Systems, methods, and devices for laser mapping and color imaging with increased dynamic range are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation, wherein the pixel array comprises a plurality of pixels each configurable as a short exposure pixel or a long exposure pixel. The system includes a controller comprising a processor in electrical communication with the image sensor and the emitter. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises a laser mapping pattern.

An image reading device includes: a first reading unit that is provided at an intermediate position of a transport path and that reads an image of a document transported on the transport path; and a transport unit that is disposed on the transport path further upstream than the first reading unit and that transports the document to the first reading unit. The transport unit includes a third driving roller and third driven rollers that hold the document between the third driving roller and the third driven rollers. The third driving roller is provided on a frame main body, and the third driven rollers are provided on a holder member. When a cover is displaced from a closed position to an open position, the holder member is moved so as to separate the third driven rollers from the third driving roller.

An image forming apparatus includes a body, an image forming device configured to form an image on a recording medium and supported by the body, an attachment configured to be removably attached to the body, and a cover configured to be removably attached to the body. The cover is configured to cover the attachment attached to the body. The attachment is configured to switch a state in use of the image forming apparatus by attaching and removing of the attachment to and from the body.
