Information terminal device and biological sample measurement device

A biological sample measurement device for use by at least one user for measuring a biological sample of at least one patient, comprising:

• a substantially cuboid main body case;
• a display component provided on a surface on the first end side of the main body case;
• an input component provided near the display component adjacent to a center of the main body case;
• a controller connected to the input component and the display component, the controller being configured to control a display of the display component;
• a sensor mounting component configured to mount a sensor thereon, the sensor being configured to have a biological sample deposited thereon, the sensor mounting component provided on a second end side opposite from the first end side of the main body case;
• a data reader provided on a first end side of the main body case, the data reader being configured to read ID's of the at least one user, the at least one patient, and the sensor;
• a finger groove provided on both sides of a part of the main body case on which the input component is provided;
• and
• a measurement component connected to the controller, the measurement component being configured to detect and measure the biological sample, wherein:
• the display component is configured to switch between a measurement screen and an input screen during a process during which input information is being displayed,
• the display component is configured to display, based on commands from the controller:
• a plurality of character keys,
• an enter key for entering input information including one or more characters inputted by selecting one or more of the plurality of character keys, and
• a selection marker indicating one of the plurality of character keys and the enter key being selected;
• the input component includes:
• a select key that causes the controller to successively move the selection marker displayed on the display component over the plurality of character keys so as to select one of the character keys,
• a first key for changing a display content displayed on the display component, and
• a set key for setting a character selected with the select key;
• the select key is formed by a cross key;
• the set key is formed by a first push button in a center of the cross key;
• the first key is formed by a second push button provided near the cross key;
• and
• the controller is further configured to:
• accept input of the input information via the input component after a start of measurement processing by the measurement component,
• display the character corresponding to a first character key in the display component when the set key has been operated in a state in which the first character key is being selected with the select key among the plurality of character keys, and
• move the selection marker displayed on the display component from the selected character key directly to the enter key when the first key has been operated in a state in which the input information is being displayed on the display component.
