A game apparatus being a non-limiting example information processing apparatus includes a display, and a game screen of a baseball game is displayed on the display. In a defensive (fielding team) side, in the game screen, a batter object and a catcher object are displayed, and an index object is displayed in front of the catcher object. Using the index object, a player designates a target position of a position that a ball object is to be thrown (pitching course) and a pitch type of the ball object, and instructs pitching. Even if the player designates the target position and the pitch type in any order, the target position and the pitch type can be set according to a designated order.

Provided is an objective lens including a diffraction portion provided on a laser beam incident plane or output plane. The diffraction portion includes first second, and third diffraction regions, wherein first laser beams corresponding to a first optical disc having a first transmissive layer are condensed on a data recording portion of the first optical disc, second laser beams corresponding to a second optical disc having a second transmissive layer thicker than the first transmissive layer are condensed on a data recording portion of the second optical disc, and third laser beams corresponding to a third optical disc having a third transmissive layer thicker than the second transmissive layer are condensed on a data recording portion of the third optical disc. An evaluation parameter calculated on the basis of an in-plane efficiency distribution function has a value corresponding to a symbol error rate that is less than a predetermined value.

A printhead mechanism and printing device capable of readily achieving adequate printing pressure are provided. The printhead mechanism includes a thermal printhead supported and pressed to a paper sheet or ink ribbon moving in a predetermined conveyance direction, a pressing mechanism pressing the thermal printhead in a direction orthogonal to the conveyance direction, a head supporting mechanism supporting the thermal printhead movably in head-pressing direction, wherein an acting point Pof a pressing-force W, at which the thermal printhead is pressed, is disposed downstream of a supporting point pat which the thermal printhead is supported.

Disclosed is a printer including a paper feeder for accommodating a rolled paper to be pulled out and recorded thereon. The feeder has a container section to set the roll, in which first and second support walls are arranged to rotatably support the roll. While paper from the roil is taken out, a contact force produced by the roll against the first support wall is kept larger than that in a stationary state, and a contact force produced by the roll against second support wall is kept smaller than that in the stationary state. A friction coefficient between the second support wall and the roll is larger than one between first support wall and the roll, the roll being in slidable contact with the first and second support walls. Therefore, when the recording is started, an impact force to the roll can be alleviated, resulting in reducing unevenness in image in a feeding direction of the paper.

An optical pick-up device in which two object lenses correct comatic aberration with respect to object lenses. First and second optical systems converge either one of light beams having first, second and third wavelengths onto an optical disc. Object lenses are displaced in three axial focusing directions including a direction perpendicular to the recording surface of the optical disc, a tracking direction radial to the optical disc, and either one of a radial tilt direction in a circular arc form on the axis of the radial direction and a tangential tilt direction in a circular arc form on the axis in a tangential direction perpendicular to the radial direction. Comatic aberration of the second optical system is corrected relative to the first optical system in the other direction of the radial tilt direction and the tangential tilt direction, which is not controlled by the object lens drive unit, is corrected.
