Title: Copy machine and storage medium
Inventor: MIZUTANI TETSUYA
IPC: B41J29/38
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a copy machine in which a recording sheet can be carried stably when recording data is copied while being transferred through an I/O buffer. SOLUTION: A CPU 10 adjusts the carrying speed of recording sheet in three stages, i.e., ultralow speed, low speed and high speed, depending on the content of data stored in an I/O buffer (RAM 12) and the volume of stored data. The CPU 10 makes a decision whether the volume of data stored in the I/O buffer exceeds a specified level or not and if it is lower than the specified level, switches the carrying speed of the recording sheet from high speed to low speed. After the carrying speed is switched from high speed to low speed, the CPU 10 prohibits switching operation from high speed to low speed and executes recording operation while keeping low or ultralow carrying speed of recording sheet.

Title: Carrying type writing implement with seal
Inventor: GOTSU MASAKI
IPC: B43K29/013
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To solve the disadvantage of a usual carrying type writing implement that the diameter of a seal thereof is small or that the implement is only a product obtained by making a part thereof thick and large and this causes dissatisfaction and imbalance, taking it into consideration that a signature and sealing have great parts for specifying a person even in the times when most of office work is conducted by a word processor or a computer and they are used frequently also in miscellaneous household or daily duties and that it is often desired on journey or in a place of staying that the carrying type writing implement should have the seal. SOLUTION: The diameter of the seal can be enlarged by expanding a holder, a cap or a part thereof to be elliptical with the thickness requisite for the carrying type writing implement left as it is. In other words, the part expanded to be elliptical is cut bias in the direction of the minor axis, so that a round face of the seal being wider by about 50% than a usual one be formed in the part. The writing implement thus obtained is excellent in a design and balance, brings about a large print of the seal and also is worthy to have.
