<p>PROBLEM TO BE SOLVED: To safely recognize the time at outdoor walking time by installing a time display means in a part visible from the outside of a case to house a baggage so as to be fixable and mountable/demountable. SOLUTION: A fixable or mountable/demountable watch 2 is arranged in a part of a briefcase 1. It is better to form a time display figure of the watch 2 larger so as to be visible, for example, even when walking by carrying the briefcase 1 by hand. A line 9 of sight when the time is recognized by the watch 2 of the briefcase 1 having a watch, can sufficiently recognize an obstacle 8 at walking time, and a user can safely walk by avoiding the obstacle 8. Since a forward visual field-hindering object does not come into view, the user can more safely walk. About 80 cm of a distance up to the watch 2 of the briefcase 1 carried by hand and about 160 cm of a distance up to the foot side become far nearer, and since the directions of the lines 9 of sight to the foot side is almost equal to each other, a visual field of the foot side can also be secured while recognizing the time by the watch 2, and the existence of an obstacle on a road can be sensed, and the user can safely walk.</p> |
