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 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.

A handheld print scanner and translator may be shaped as a working pen, and may provide for a scanner on one side of its body and a display screen on the other side of its body. In some embodiments, the present invention may provide for a button wheel on the present invention's base that may be configured to operate the scanner and determine what form or type of output may be displayed on the display screen. In some embodiments, a processor may translate one or more scanned words or phrases from a printed page, whether physical page or electronic screen, and may display a translation of the text on the display screen.

The disclosure is related to a positioning module and a handheld scanner using the same. The positioning module includes a base, a rotation support member, a shaft body, a wheel, a first sensor, and a second sensor. The rotation support member is pivoted to the base and rotates relative to the base about the first axis. The shaft body and the wheel are pivotally contacted to the main body and in constant contact with each other. When the wheel is rotated about a second axis due to a frictional force, the main body displace linearly and the shaft body is driven to rotate. Since the second axis is offset by the first axis, the rotation support member is driven to rotate at an angular displacement synchronously. The first and second sensors detect the shaft body and the main body to obtain the linear and angular displacements for positioning.

An image acquisition system according to the present invention includes: a display device including a display surface on which a subject can be mounted; and the image acquisition device that is disposed face-down at a position above the display device in a manner spaced apart from the display surface, the display device being disposed with the display surface face-up, and that acquires images of the display surface and the subject placed on the display surface, wherein the image acquisition device includes a transmission unit that transmits the acquired images, and the display device includes: a reception unit that receives the transmitted images; a relative-position calculation unit that calculates the relative position between the display device and the image acquisition device on the basis of the received image; and a display control unit that controls content displayed on the display surface on the basis of the calculated relative position.
