Abstract: A cutter of the present invention comprises a punching member having a punching edge and a receiving member for receiving the punching force of the punching member, the receiving member having a sandwich structure comprising two plate materials and an elastic body held therebetween. Therefore, the receiving member is capable of elastically holding the punching edge during punching.

Abstract: A cassette which retains a plurality of stacked resin sheets is loaded on a retaining member of a driving device. A plurality of press-heating stations and a number of cooling stations which is smaller than the number of press-heating stations are disposed around the driving device, and the retaining member is sequentially sent to each of the stations by means of the driving device. In each press-heating station, each of the resin sheets in the cassette retained by the retaining member is thermowelded, and the press-heated resin sheets are cooled in the cooling station. The cassette comprises a cassette body for accommodating a plurality of stacked resin sheets, and a pressing plate brought into contact with the stacked resin sheets so as to press them by means of a resilient member such as a coned disk spring. Thus, the resin sheets are moved from one press-heating station to another while being maintained in a pressed state.

Abstract: In a film cutter which is activated at the end of the film by a film end detection signal, the length of film transported is monitored and the cutter is activated only if the film end detection signal occurs during predetermined ranges of film length.
