Abstract: This electronic information terminal includes a display panel having a rectangular display area, an angle sensor detecting rotation angle information, and a display control portion controlling switching of the display orientation of the display panel on the basis of a detection result of the angle sensor. The display control portion is configured not to switch the display orientation when the turning angle velocity of the display panel based on the rotation angle information is smaller than a first threshold.

Abstract: In a printer that forms an image on a color thermal recording paper by using a thermal recording head, a preheating region of the recording paper that is used for preheating the thermal recording head in a process prior to formation of the image and disposed of as a cut piece can effectively be used. An image forming control unit preheats a part of the thermal recording head in each end region that contact with the recording paper for heating the thermal recording heat to a proper temperature just before forming an image on the recording paper. While preheating of the thermal recording head, the image forming control unit further controls the thermal recording head for printing arbitrary information such as residual quantity of the recording paper on a portion between preheated portions of the recording paper to be disposed as the cut sheet.

Abstract: A printer having a function for printing index prints comprises a connector to which a recording medium can be connected, a data reader for reading image data from the recording medium through the connector, a memory for memorizing a plurality of kinds of templates, a controller for selecting the most suitable template corresponding to a number of thumbnail images to be printed as the index prints, and a printing mechanism for printing the index prints on paper sheets. The controller calculates a minimum number of the paper sheets necessary for printing the index prints corresponding to the numbers of the boxes of the templates and a number of thumbnail images to be printed as the index prints, and selects one template having the largest size of the boxes among the templates by which all the thumbnail images can be arranged on the minimum number of the paper sheets.
