摘要:
A mobile terminal as a mobile terminal includes a storage unit which stores an action pattern record table having at least one action pattern registered preliminarily in correlation with addressee information, a control unit which obtains position information of the mobile terminal via a GPS antenna to identify the action pattern based on the position information obtained by a receiver in reference to the stored action pattern record table responding to the request for activating a redial function, and a main display which displays the addressee information in accordance with the priority of the addressee information correlated with the action pattern identified by the control unit in reference to the action pattern record table.
摘要:
If a print misregistration amount on a sheet is larger than a predetermined threshold before determining whether a printed image is appropriate or not, an abnormal status of the image printed on the sheet is detected without correcting image data for inspection. A control method for controlling a detecting apparatus for inspecting a print status of an image printed on a sheet by a printing apparatus includes detecting, in a case where it is determined that a print misregistration amount of the image printed on the sheet with respect to the sheet is larger than a predetermined threshold, an abnormality of the print status of the image read by a reading unit without performing correction.
摘要:
The present invention provides an antenna that is small in size and has band frequencies corresponding to multibands, and a wireless communication apparatus including the antenna. The antenna according to the present invention has two radiation elements 12a and 12b connected to a ground plate 11 via a shorting pin. The two radiation elements 12a and 12b each have a lower arm and an upper arm that are formed through bending. The lower arm is connected to the shorting pin and is located closer to the ground plate 11 than the upper arm is. At least one of the lower arm and the upper arm has a meandered structure.
