초록 ▼

A punch is disclosed, which can be used with an automatic paper feeder or a plane paper copier for receiving sheet-like members one by one from such machine and forming punched holes in each sheet-like member at a punching position thereof. A punching member is disposed in correspondence to the punching position for effecting punching with a predetermined stroke. A dimensional strain generated in an electrical-to-mechanical conversion element such as a piezoelectric element or a magnetostriction element is transmitted after enlargement by an enlarging member disposed to surround the element through a movable output terminal and an operation transmission lever to the punching member to cause high speed operation thereof in a predetermined stroke range. High quality punched holes free from curved edges or the like difficiency thus can be formed even in a continuous feed state without holding the sheet-like members stationary for a while.

대표청구항 ▼

A punch connected to a machine such as an automatic paper feeder or a copying machine for receiving sheet-like members one by one, which are sent from said machine, and forming punched holes for filing in each sheet-like member at a predetermined punching position thereof, comprising: feeding means for feeding each received sheet-like member along a feed path, said feeding means including a feed roller mechanism and a DC motor driving said feed roller mechanism; position determination means for determining said predetermined punching position, at which each sheet-like member fed by said feeding means is punched, said position determination means including sensor means operative for detecting one of the leading and trailing ends of the sheet-like member in said feed path and providing an electrical detection signal; a punching member opposing said predetermined punching position and capable of executing a punching operation with a predetermined stroke to form punched holes for filing in the sheet-like member at said punching position thereof; first electrical-to-mechanical conversion element means for generating a predetermined amount of dimensional strain upon receipt of said electrical detection signal; first enlargement means for enlarging the dimensional strain generated in said first electrical-to-mechanical conversion element means and transmitting the enlarged dimensional strain to said punching member, thereby causing execution of the punching operation of said punching member with said predetermined stroke; and guide means defining said feed path and offering a predetermined feed resistance to the sheet-like member being fed along said feed path, wherein: said feed roller mechanism includes a drive roller and a driven roller, said feed roller mechanism being shiftable between an operative position, in which said driven roller is urged against the drive roller to feed said sheet-like member in a pinched state with a predetermined feeding force and an inoperative position, in which said driven roller is disengaged from the drive roller to provide substantially no feeding force to said sheet-like member, without stopping the driving of the DC motor; said position determination means further includes a shifting mechanism for shifting said driven roller from said operative position to said inoperative position temporarily in response to the operation of said sensor means to have said sheet-like member released from said feeding force and held stationary momentarily at said predetermined punching position; and said guide means includes a pair of substantially parallel guide plates defining said feed path therebetween, and includes a brake portion operable in response to the shift of said driven roller from said operative position to said inoperative position to urge the running sheet-like member against one of said guide plates, thereby braking the sheet-like member.
