BACKGROUND OF THE INVENTION
  The present invention provides a portable learning device in which a first operating means is arranged at a position where it can be operated with one thumb when held with both hands, and a second operating means is arranged at a position where it can be operated with the other thumb. It is about.
[0002]
[Prior art]
  As is well known, a portable learning machine with a liquid crystal display has been proposed in which a portable game machine type main body is equipped with a cartridge containing a storage element storing learning support program data so that learning can be performed anywhere. For example, Japanese Utility Model Publication No. 7-14462 discloses a portable game machine type portable learning machine that helps memorize word idioms.
[0003]
  Further, in the portable game machine employed in the conventional portable learning machine, a cross-shaped direction key having both upper, lower, left and right end portions as push buttons, and a cross having raised crosses having the same up, down, left and right push buttons. A direction key consisting of a plate-shaped direction key and four push buttons positioned at the tip of the cross shape is arranged on the left side of the liquid crystal display unit, and a determination function and a setting function are provided on the right side of the liquid crystal display unit. A plurality of push buttons are provided apart from each other and arranged as decision / setting keys.
[0004]
[Problems to be solved by the invention]
  In the conventional portable game machine type portable learning machine, the direction key and the determination / setting key of the portable game machine are used as they are, but the shape and arrangement position of the push button of the portable game machine is in progress. In order to transmit character trouble avoidance movements and instantaneous active movements from the above keys immediately without stress, the direction key push buttons are formed in the same shape and height to enable integrated movement, allowing them to move vertically and horizontally The direction to move the character required to capture the game in order to avoid the erroneous operation by realizing the push and providing the push button of the decision / setting key separated by the same shape and the same height. And the agility of the pressing operation can be increased. In addition, since it is assumed that the operation is always performed with both thumbs, the game machine main body is held with both hands during the operation, so there is no need to consider the fluctuation of the display screen of the liquid crystal display unit. The outer shape has a uniform thickness.
[0005]
  However, for example, in a learning support program that increases the academic ability of a subject, in a subject that is studied at elementary, junior high and high schools, the contents of the subject are understood and the degree of achievement is memorized. Therefore, a long sentence explaining the important matter is displayed on the liquid crystal display unit, and a learning method that evokes the important matter and a card that describes the question that answers the important matter A learning method is used to repeatedly review the wrong question cards.
[0006]
  Therefore, in the former learning method, there are many operations for moving a long sentence, and in the latter learning method, there are many operations for hitting a question card or for separating a remembered question card from an unremembered question card. If the direction key and the determination / setting key of the portable game machine are adopted as they are, there is a case where either the direction key or the determination / setting key is operated depending on the learning method, and the learning in the former learning method is performed. When the support program is executed and when the learning support program in the latter learning method is executed, the direction key and the determination / setting key are used differently, and the main body holding force by the operating thumb and the main body by the playing thumb Since the difference between the holding force and the decision / setting key, the push button that is far away is pressed, so the thumb on the operating side is pressed. Because it has to be moved, the main body shakes during learning, the display screen fluctuates, and it is difficult to learn for learners who take time to concentrate and concentrate. There is a problem that the shape and the push button arrangement are not suitable for a learning machine that requires poor concentration and concentration.
[0007]
  Furthermore, it is required that the portable learning machine does not choose the place and time to use it. Depending on the place and the learning method of the learning support program, it is often operated with one hand, so hold it with both hands. The conventional portable learning machine that adopts the shape of the main body of the portable game machine, which is assumed to be operated, has a problem in that the display screen of the liquid crystal display unit fluctuates and the learning cannot be concentrated.
[0008]
  Therefore, the present inventors are able to use learners who take time to concentrate as well as learners who regularly use portable game machines without resistance, and can learn without disturbing the display screen even if they are operated with one hand. As a technical problem to provide a portable learning device that can concentrate on the mobile phone, as a result of repeated research and experimentation to realize its implementation, the direction key in the portable game machine, the up and down push buttons, If the left and right push buttons are separated into the left and right push buttons, which are horizontally long between the lower push buttons and both ends are raised higher than the upper and lower push buttons and are left and right push buttons, Even if you hold it, you can read the text displayed in horizontal writing, just by turning the thumb left and right according to the movement of your eyes, pressing the left and right push buttons without pressing the up and down push buttons Display according to movement The left and right push buttons are integrated, so that the thumb can be easily pressed by moving the center of gravity of the thumb by turning the thumb, and the minimum pressing force of the thumb Therefore, the above technical problem has been achieved by obtaining a remarkable knowledge that the display screen does not fluctuate even when the main body is held with one hand.
[0009]
  In addition, a round-headed circular push button for a determination / setting key in the portable game machine, and a round-headed first-cursor moon-shaped push button arranged on the upper side adjacent to the circular push button and away from the liquid crystal display unit; The upper and lower lunar push buttons have the same height as the round crescent push button that divides into the circular push button and is located on the lower side adjacent to the liquid crystal display. If the center push button and the upper and lower push buttons are adjacent to each other, the head of the center push button higher than the upper and lower push buttons is spherical. Therefore, it is possible to take a distance between the center push button and the upper and lower push buttons, and when the center push button is pressed by the thumb touching the head of the push button, a sufficient sense of distance is felt. Incorrect push buttons up and down There is no pressing, and the heads of the upper and lower push buttons are also spherical, so the contact area with the thumb is expanded, and the thumb placed on the central push button feels a sense of unity with the upper and lower push buttons. Furthermore, since the three push buttons are lined up in a direction away from the liquid crystal display unit, the upper and lower push buttons can be easily pressed by simply turning left and right without moving the thumb. The above technical problem has been achieved by obtaining a remarkable knowledge that the display screen does not fluctuate.
[0010]
  Further, the left and right push buttons of the first operation means and the round-headed circular push button of the second operation means are set on the center line on the lower side of the main body or on the center line near the center line. Because it is positioned on a parallel line, even if you operate with one hand and press one of the push buttons of the first operation means and the second operation means, the balance of the main body with one hand will not be lost, The inventors have obtained a remarkable knowledge that further stability can be ensured, and have achieved the technical problem.
[0011]
