PURPOSE:To obtain tasteful changing patterns and to guess the time while obtaining a fixed pattern at a fixed time by moving a pattern linearly and in a fixed direction in the display window of a case with the passage of time. CONSTITUTION:A gear 20 rotates at a specified speed and rotates a gear 15 of a rotating mechanism 11 at a specified rotation ratio, and drives a roller 12 and rotates a film 13 at a fixed speed once in 2hr. At the same time, a gear 10 of a rotating mechanism 6 is rotated at specified rotation ratio, and a roller 7 is driven to rotate a film 8 at a fixed speed once in 24hr. Consequently, a background pattern 17 is visible in a display window 5 through films 8, 13, and at the same time, a pattern 9a for indicating hour moves linearly to the right at a fixed speed, and a pattern 14a for indicating minute moves linearly to the left. Accordingly, patterns 9a, 14a become a fixed positional condition at a fixed time in the window 5. Thus, time can be guessed by positional condition of patterns 9a, 14a. |
