分針４及びアラーム針５を取り付けて組立を終了する。At the time of assembly, a timepiece mechanical body (not shown) is attached to the back surface of the timepiece frame 1, the pointer shaft is made to project to the front surface, the printed circuit board 8 is fixed to the front surface of the bottom portion 1c, and then the concave portion 1e and the projection portion are provided. The double-sided adhesive tape 10 is attached so as to straddle the recess 1e and the recess 1e. Then, the light diffusion plate 7 is locked with the positioning tongue 7h in the positioning hole 1h, and the light receiving plate 1b is received.
When pressed upward, as shown in FIG. 5, the back surfaces on both sides of the cutout portion 7d of the light diffusion plate 7 are adhered to the tape on both ends of the double-sided adhesive tape 10 and above the recess 1e. Nothing has yet been adhered to the tape on the protrusion 1d, which is the central portion of the double-sided adhesive tape 10. Subsequently, when the dial 2 is pressed against the receiving surface 1b by engaging the positioning tongue 2h with the positioning hole 1h, the protrusion 1 located in the notch 7d of the light diffusing plate 7 is pressed.
The back surface of the dial 2 is bonded to the double-sided adhesive tape 10 on d. Since the double-sided adhesive tape 10 projects from both ends by the projections 1d, the back surface of the dial 2 and the front surface of the light diffusion plate 7 are at substantially the same level in the bonded state. For this reason, there will be no inconvenience such as waviness at the bonded portion of the dial plate 2. The hour hand 3 on the pointer shaft protruding from the dial 2,
The minute hand 4 and the alarm hand 5 are attached to complete the assembly.

This light passes through the light transmitting portion 7e and the light transmitting scale 2e and emits light in the forward direction, which brightly displays the position at the hour in the dark. Further, the light from the LEDs 9 spreads through the light diffusing plate 7 and causes a stripe pattern due to the light to appear on the light transmitting portion 2a, as shown at 3:00, 4:00 and 5:00 in FIG. As a result, the hour hand 3, the minute hand 4, the alarm hand 5 and the alarm scale 2f can be easily seen.
