Abstract

An insert carriage having a manipulating member attached thereto for inserting an enclosure into an envelope is arranged reciprocally in the direction of said envelope. By moving said insert carriage, said manipulating member may be reciprocated between the basic position and the position of the fold line of said envelope which is the inserting position. A carriage motor for driving said insert carriage is provided. A control unit is provided, said control unit comprising a variable amount inputting section adapted to input the variable amount is respect to the inserting position of the manipulating member in conformity with the thickness or quality of paper of said envelope, a memory section adapted to store said variable amount and a CPU section adapted to controllably drive said carriage motor in accordance with the variable amount store in said memory section to adjust the inserting position of said manipulating member.

Dependent claims

A method of enclosing and sealing comprising the steps of;

arranging an insert carriage in a manner to be reciprocatable in the direction of an envelope, said insert carriage having a manipulating member for abutting an enclosure against an enclosure attached to a base having the upper surface onto which a specified enclosure is supplied, the envelope being disposed with a foldable flap connected to the mouth portion of the envelope via a fold line being located to the side of said enclosure at one side of the base;
reciprocally moving said manipulating member between a basic position and an insert position corresponding to said fold line of the envelope by moving said insert carriage;
providing a carriage motor for driving said insert carriage;
inputting variable amounts for indicating the desired insert positions of said manipulating member in conformity with the thickness or quality of paper of the enclosure;
storing an insert pulse number based on said variable amounts;
detecting the starting timing respectively of an insert operation and a return operation in accordance with the rotary angle of the carriage motor;
and
rotationally controlling said carriage motor toward said envelope by the amount corresponding to said insert pulse number when said detecting step has detected that the insert operation can be started and away from said envelope by the amount corresponding to a return pulse number when said detecting step has detected that the return operation can be started.

An enclosing and sealing apparatus comprising a base having an upper surface onto which a specified enclosure is supplied, a specified envelope being disposed with a foldable flap connected to the mouth portion of the envelope via a fold line being located to the side of said enclosure, and an insert carriage with a manipulating member for abutting against the enclosure being arranged on the base in a manner to be reciprocatable toward the envelope, and adapted to reciprocatably move the manipulating member between a basic position and an insert position by moving the insert carriage, said enclosing and sealing apparatus further comprising:

a carriage motor for driving said insert carriage;
a variable amount inputting section for inputting variable amounts for designating the desired insert positions of said manipulating member in conformity with the thickness or quality of paper of the enclosure;
a memory section for storing an insert pulse number based on the variable amounts;
an operation starting position comparison section for detecting the starting timing respectively of an insert operation and a return operation in accordance with the rotary angle of the carriage motor;
and
a control unit for rotating said carriage motor in the direction of said envelope by said insert pulse number when said operation starting position comparison section detects the possibility of starting of the insert operation and for rotating said carriage motor in the opposite direction of said envelope by a return pulse number when said operation starting position comparison section detects the possibility of starting of the return operation.
