Patent number: 5619292Abstract: A camera using films each having a development processing solution in a solution accommodating bag includes rollers feeding photographed film outside of the camera or into an accommodating chamber, a piezoelectric press member held between an electrode and an elastic member also serving as an electrode presses photographed film and spreads development processing solution in the solution bag over an entire exposing portion. A piezoelectric member vibrated by AC voltages applied to the electrode and elastic member reduces a frictional force of the film caused by the press member. The processing solution is heated by vibrating the press member to generate heat.Type: GrantFiled: May 22, 1995Date of Patent: April 8, 1997Assignee: Olympus Optical Co., Ltd.Inventors: Minoru Matsuzaki, Yuta Sato, Sumio Kawai, Hiroyuki Takizawa, Masaharu Hamada, Tomoki Funakubo

Patent number: 5469237Abstract: A data printing apparatus of this invention controls the emission timing or the emission interval of a light-emitting means on the basis of a signal according to traveling of a sheet film along a traveling path so as to print data free from blurring of characters or a variation in interval between characters on the sheet film having no perforations. After an exposure operation is ended, the apparatus feeds the sheet film from an exposure position along a spool wall. Light corresponding to digital numerals representing a date is emitted by light-emitting elements, and the date to be printed by the light-emitting elements is focused on the sheet film by an optical system. The date on the sheet film is printed during traveling of the sheet film along the spool wall.Type: GrantFiled: December 8, 1993Date of Patent: November 21, 1995Assignee: Olympus Optical Co., Ltd.Inventors: Junichi Itoh, Yuta Sato, Minoru Matsuzaki, Masaharu Hamada, Yuji Imai
