Abstract
A light transmitting type display plate 5 is arranged above a cell 2 such as an EL element or a solar cell or the like, and the display plate 5 is fixed to the support member 4 through the engagement of a positioning section 5b formed on the light transmitting type display plate 5 with a positioning section 4b formed on a support member 4. In the case where the light transmitting type display plate is a transparent plate 5, a spacer 6 or the like forms a gap 7 between the cell 2 and the transparent plate 5.
Claims21
A watch comprising,
- a movement,
- a cell made of one of a light-emitting member and a light-absorbing member laminated onto the movement,
- a support member disposed above the cell for fixing the same,
- a light transmitting type display plate formed of one of a transparent plate and a semitransparent plate add arranged above the cell,
- means for forming a gap disposed between the display plate and the cell, said gap forming means preventing formation of light interference fringes over the cell, and
- positioning means having a first positioning section formed on the support member and a second positioning section formed on an outer periphery of the light transmitting type display plate, said first and second positioning sections being engaged together so that the display plate and the cell are fixed relative to the support member, and an additional gap is formed between the outer periphery of the display plate except the second positioning section and an inner periphery of the support member except the first positioning section.
